Technical Field

The invention belongs to the technical field of blockage clearing, and particularly relates to a blockage clearing structure and a blockage clearing system.

Background

In the fields of petroleum, chemical industry, building, environmental protection, steel and the like, a large number of containers and pipelines are applied, many containers are pressure containers or pressure pipelines, and a part of the containers are normal pressure containers or normal pressure pipelines (which are not specifically described below and are called as 'equipment' or 'container' for convenience of description), media in the containers mostly contain impurities, and the materials in the containers can be divided into the following types according to the phase states of the media and the impurities: gas medium + liquid impurity, gas medium + solid impurity, liquid medium + solid impurity, gas medium + liquid impurity + solid impurity, solid medium + liquid impurity + solid impurity, etc. During the operation of the apparatus, some substances may accumulate to some extent at the bottom of the vessel due to separation or due to gravity, temperature changes, flow changes, etc. The accumulated substances are solid (such as sand, rust, dust and other solids), liquid (such as water, oil, liquid hydrocarbon and other liquids), liquid + solid (such as water + sand, oil + sand, water + oil + sand, water hydrocarbon oil + solid substances), and the accumulated substances need to be discharged through a sewage pipeline and a sewage valve according to a certain time. In the actual process of petroleum, petrochemical and industrial production, solid substances (such as sand grains and powder) or liquid with high viscosity are gradually accumulated at the bottom of the container due to various reasons, such as failure of a sewage discharge system, overlong sewage discharge period, impurity content exceeding the sewage discharge capacity of the sewage discharge system, untimely sewage discharge and other factors and process parameter changes, and gaps among the blocking objects are gradually reduced and the stacking density is gradually increased under the combined action of gravity and medium pressure in the container. If the blockage prevention measures are not adopted for dredging in time, the accumulated substances can continue to accumulate to a certain degree, a sewage discharge pipeline at the bottom of the container or the lower part of the container can be blocked, a sewage discharge system loses the sewage discharge function, and the risk is brought to the normal operation of equipment.

Since the interior of the vessel needs to be maintained at the same pressure as the medium during operation, a typical unblocking structure needs to be disposed in the vessel or in the same space as the interior of the vessel in order to maintain the pressure inside the vessel. The current blockage clearing structure meeting the conditions usually adopts a linear transmission part to drive the blockage clearing piece to do linear reciprocating movement, and the aim of clearing the blockage of the sewage system is achieved through the linear reciprocating movement of the blockage clearing piece near the sewage discharge outlet or in the sewage discharge pipeline. Especially when the length of a sewage pipeline to be cleaned is long, the reciprocating movement stroke of the blockage cleaning piece needs to be correspondingly increased, and the occupied space is increased in proportion, so that the blockage cleaning structure is difficult to arrange.

Therefore, it is necessary to provide a blockage clearing structure and a blockage clearing system.

The specific meaning of the above terms can be understood by those of ordinary skill in the art as appropriate.

Reference herein to the terms "first, second, third and fourth" are intended merely to distinguish similar objects and do not denote a particular order or importance to the objects, but rather the terms "first, second, third and fourth" are intended to be interchangeable under the appropriate circumstances. It should be understood that the terms "first," "second," "third," and "fourth" are used interchangeably where appropriate to refer to embodiments of the application described herein and may be implemented in sequences other than those illustrated or described herein.

As shown in fig. 1 to 2, according to an embodiment of the present application, there is provided a blockage clearing structure including: the transmission piece 10 is provided with a first section 101, a blockage removing section 102 and a second section 103 which extend in sequence along the length direction, wherein the first section is a flexible section; two pressure-resistant chambers, for example, a first pressure-resistant chamber 20 and a second pressure-resistant chamber 30, the first pressure-resistant chamber 20 having a first pressure-resistant chamber connection inlet 201, the second pressure-resistant chamber 30 having a second pressure-resistant chamber connection inlet 301 and a second pressure-resistant chamber connection outlet 302; the first driving assembly 40 includes a first rotating member 401, at least a portion of the first rotating member 401 is located in the first pressure-resistant chamber 20, the first rotating member 401 is capable of rotating around a first rotating shaft, and the first section 101 extends from the first pressure-resistant chamber connection port 201 into the first pressure-resistant chamber 20 and is connected to the first rotating member 401; the first segment 101 can be wound by the first rotating member 401 in the process that the first rotating member 401 rotates around the first rotating shaft in the first direction, and the first segment 101 can be unwound by the first rotating member in the process that the first rotating member 401 rotates around the first rotating shaft in the direction opposite to the first direction; the second driving assembly 50 comprises a tension member 501, at least a part of the tension member 501 is located in the second pressure-resistant chamber 30, and the second segment 103 extends into the second pressure-resistant chamber 30 from the second pressure-resistant chamber connection inlet 301 and is fixedly connected with the tension member 501; the tension piece 501 can apply tension far away from the first section 101 to the second section 103 in the processes of winding and unwinding the first section 101 by the first rotating piece 401; in the process of winding and unwinding the first section 101, the blockage removing section 102 reciprocates along a straight line and is simultaneously subjected to reverse tension from the first section 101 and the second section 103; the block clearing member 60 is disposed on the block clearing section 102.

In order to achieve a better blockage clearing effect, the blockage clearing piece and the movement direction of the blockage clearing section can form an angle, and the angle can be larger than zero and smaller than 180 degrees, for example. For example, in the present embodiment, the direction of movement of the block removing member and the block removing section is 90 degrees. It should be understood that the block clearing member may be arranged parallel to the moving direction of the block clearing section, and in this case, it is understood that the solution also includes the case where the block clearing member forms part of the block clearing section, thereby increasing the cross-sectional area of the block clearing section to improve the block clearing effect.

Considering that the blockage clearing structure adopting the linear transmission part to drive the blockage clearing part to do the linear reciprocating movement needs to occupy a larger space in the reciprocating movement direction of the blockage clearing part, in order to save the occupied space of the blockage clearing structure as much as possible, the blockage clearing structure can also comprise a first guide part 70, as the first section 101 is a flexible section, the first section 101 can rotate around a first rotating shaft by arranging a first rotating part 401, and the first section 101 can be wound by the first rotating part 401 in the process that the first rotating part rotates around the first rotating shaft in the first direction, and then the guiding effect of the first guide part 70 is assisted, so that the extending direction of the first section 101 is changed after passing through the first guide part 70. The first guiding element 70 may be in the form of a guiding rod, and the extending direction of the first segment 101 is changed after passing through the first guiding element 70, for example, an angle α 1 may be formed between the initial extending direction of the first segment 101 and the extending direction after passing through the first guiding element 70, where α 1 ≧ 0 (which is a special case of changing the extending direction when α 1 ═ 0). As shown in fig. 1, in the present embodiment, as a specific implementation manner, α 1 is 90 degrees.

In this embodiment, the blockage clearing structure may further include a first limiting member 80 for limiting a travel track of the first segment 101 between the first guide member 70 and the first rotating member 401, so as to prevent the first segment 101 from swinging back and forth between the first guide member 70 and the first rotating member 401 when blockage clearing is performed. The first limiting member 80 can take various forms. For example, the first limiting member 80 may be a groove extending between the first rotating member 401 and the first guiding member 70, the groove may be U-shaped, and the first segment 101 moves in the groove; as an alternative, the first limiting member 80 may be a pipe disposed to extend between the first rotating member 401 and the first guiding member 70, and the first segment 101 moves in the pipe; as another alternative, the first retaining member 80 may be two blocking members disposed on the first guide member, and the first segment 101 moves between the two blocking members; as a further alternative, the first limiting member includes at least one set of limiting members disposed between the first rotating member 401 and the first guiding member 70, each set of limiting members includes two limiting members disposed on opposite sides of the first segment, and the axial directions of the two limiting members are perpendicular to the axial direction of the first segment sandwiched between the two limiting members. Specifically, as shown in fig. 2, the first limiting member 80 includes a first set of limiting members 801 and a second set of limiting members 802 disposed between the first rotating member 401 and the first guiding member 70, the first set of limiting members 801 and the second set of limiting members 802 respectively include two limiting members disposed on two opposite sides of the first segment, and an axial direction of the two limiting members is perpendicular to an axial direction of the first segment 101 sandwiched between the two limiting members.

In this embodiment, in order to further save the occupied space of the anti-blocking structure and increase the flexibility of the blockage clearing operation, the second section 103 may be a flexible section; the tension member 501 may be a second rotating member, and the second rotating member can rotate around a second rotating shaft; the second segment 103 can be wound by the second rotating member in the process that the second rotating member rotates around the second rotating shaft in the second direction, and the second segment 103 can be unwound by the second rotating member in the process that the second rotating member rotates around the second rotating shaft in the direction opposite to the second direction.

Further, the block clearing structure may further include a second guide 90, and the extending direction of the second section 103 is changed after passing through the second guide 90. Similar to the first guide 70, the second guide 90 may be in the form of a steering rod, the extension direction of the second segment 103 being changed after passing through the steering rod, for example, the initial extension direction of the second segment 103 and the extension direction after passing through the second guide 90 may have an angle α 2, α 2 ≧ 0. As shown in fig. 1, in the present embodiment, as a specific implementation manner, α 2 is 90 degrees.

In this embodiment, the blockage clearing structure may further include a second limiting member 100 for limiting a travel track of the second segment 103 between the second guide 90 and the pulling member 501, so as to prevent the second segment 103 from swinging back and forth between the second guide 90 and the pulling member 501 when blockage clearing is performed. The second limiting member 100 can take various forms. The second position-limiting element 100 may be in the form of a groove, a pipe, two blocking elements disposed on the second guiding element 90, or at least one set of position-limiting elements disposed between the second guiding element 90 and the pulling element 501, in the same manner as the first position-limiting element 80, and will not be described herein again. Specifically, in the present embodiment, the second limiting member 100 may include a third limiting member and a fourth limiting member (not shown) disposed between the second guiding member 90 and the pulling member 501, where the third limiting member and the fourth limiting member respectively include two limiting members disposed on two opposite sides of the second segment 103, and an axial direction of the two limiting members is perpendicular to an axial direction of the second segment 103 sandwiched between the two limiting members.

In this embodiment, the first driving assembly 40 may further include a first driving member, and the first rotating member 401 is coaxially connected to the first driving member 40 and is configured to drive the first rotating member 401 to rotate around the first rotating shaft; the second driving assembly 50 further comprises a second driving member, and the second rotating member is coaxially connected to the second driving member and is configured to drive the second rotating member to rotate around the second rotating shaft.

In this embodiment, the first pressure-resistant chamber 20, the first driving assembly 40, the first rotating member 401 and the first driving member may be integrated into a valve structure, for example, a gate valve with a valve plate removed, and the valve structure may be used in the blockage removing structure of the present application by modifying the valve structure.

Because the valve rod and the valve body are connected through the sealing structure, when the valve structure is communicated with the container (the container to be cleaned), the pressure in the container can be kept not to be decompressed. Correspondingly, the second pressure-resistant chamber 30, the second driving assembly 50 and the second turning member and the second driving member may also be integrated into another valve structure, for example, another gate valve with the valve plate removed, wherein the space inside the valve body forms the second pressure-resistant chamber 30, the valve stem of the gate valve may be used as the second turning member in this application, and the handle of the gate valve may be used as the driving member in this application to provide the power for the turning of the second turning member. Of course, it should be understood by those skilled in the art that the power for rotating the first rotating member 401 or the second rotating member may be manual or non-manual, or powered by both manual and non-manual. If manual operation is adopted, the handle or the hand wheel is replaced by the driving head through at least one of the handle or the hand wheel, the ratchet mechanism, the wrench and the sleeve, and if the manual operation is not adopted, the driving force of the driving head can be an electric motor or a pneumatic or hydraulic motor.

In another embodiment, the tension member 501 may be an energy storage element fixed in the second pressurizable chamber 30 and connected to the second segment 103; the energy accumulating element is capable of increasing and accumulating the energy in the energy accumulating element during rotation of the first rotating member 401 about the first axis of revolution in the first direction, and the energy accumulating element is capable of releasing the accumulated energy during rotation of the first rotating member 401 about the first axis of revolution in the direction opposite to the first direction, in which case the second pressure withstanding chamber 30 accommodating at least a part of the tensile member 501 may take the form of an integrated valve structure as described above, in which case one end of the energy accumulating element is fixed in the valve structure and the other end is connected to the second section 103; alternatively, a portion of the waste pipe described below may be provided as the second pressure chamber 30, in which case one end of the energy accumulating element is fixed in the waste pipe. In this embodiment, the second segment 103 may be in the form of a flexible segment or a rigid segment, and the energy storage element may be one or a combination of a spring, an energy storage, and a damper. As an embodiment, when the tension member 501 is a spring as shown in fig. 1, the left end of the spring is fixed, and the right end is connected to the second segment 103, the spring is gradually elongated and stores energy during the rotation of the first rotating member 401 around the first rotating shaft in the first direction, and the stored energy is released and gradually restored during the rotation of the first rotating member 401 around the first rotating shaft in the direction opposite to the first direction. As another embodiment, when the tension member 501 is a spring as shown in fig. 1, the right end of the spring is fixed, and the left end of the spring is connected to the second segment 103, the spring is gradually compressed and stores energy while the first rotating member 401 rotates in the first direction around the first rotating shaft, and the stored energy is released and is gradually restored while the first rotating member 401 rotates in the direction opposite to the first direction around the first rotating shaft.

When the energy storage element is fixed at the left end, the piston rod is pulled to move to the left during the rotation of the first rotating member 401 around the first rotating shaft in the first direction, the compressible fluid in the piston cylinder is compressed and stores energy, and the compressible fluid releases the stored energy and causes the piston to move to the right during the rotation of the first rotating member 401 around the first rotating shaft in the direction opposite to the first direction.

According to a third embodiment of the present application, there is provided a blockage clearing method including: (1) the first rotating member 401 is driven by an external force to rotate around the first rotating shaft in the first direction, so that the first section 101 of the transmission member 10 is wound by the first rotating member 401, and the blockage removing section 102 of the transmission member 10 is driven to move upwards along a straight line. At this time, when the tension member 501 is a second rotating member, the second rotating member rotates with the traction of the transmission member 10, and when the tension member 501 is an energy storage element, the energy storage element is gradually elongated and stores energy under the traction of the transmission member;

(2) when the tension member 501 is a second rotating member, the second rotating member is driven to rotate around the second rotating shaft in the second direction by an external force, so that the second section 103 of the transmission member 10 is wound by the second rotating member, and the blockage removing section 102 of the transmission member 10 is driven to move downwards along a straight line; when the tension member 501 is an energy storage element, the energy storage element releases the energy stored in step (1) and gradually resets, thereby driving the blockage removing section 102 of the transmission member 10 to move downwards along a straight line.

When the step (2) is performed, an appropriate operation may be selected according to the blockage condition of the container, for example, in the case of serious blockage, an external force may be applied to the first rotating member 401 to rotate the first rotating member 401 around the first rotating shaft in the direction opposite to the first direction in the process of driving the second rotating member to rotate around the second rotating shaft in the second direction or gradually resetting the energy storage element; whereas in the case of a light jam, an external force may be applied to the first rotating member 401 to reduce the speed at which the first rotating member 401 rotates following.

(3) And (3) repeating the step (1) and the step (2) until the pollution discharge is smooth.

In the above steps, the driving order of the first rotating member 401 and the second rotating member may be interchanged, that is, the second rotating member may be driven in step (1) first, and then the first rotating member may be driven in step (2).

In this embodiment, the triggering principle of the opening blockage removal step may include three ways, one way is: starting the steps every certain time; the second method comprises the following steps: through the pressure difference between the inlet and the outlet of the container (which can be the pressure difference between the inlet and the outlet of the medium gas, or the pressure difference between the atmosphere and the medium in the equipment when the container and the blow-down valve are opened, or the pressure difference between the blow-down valve and the atmosphere after the blow-down valve is opened), the pressure difference can be detected as a differential pressure gauge or a differential pressure transmitter or a front pressure gauge and a rear pressure gauge (a is more than or equal to 2), and when the pressure difference reaches q bar (q is more than or equal to; the third method comprises the following steps: and when the second sewage draining pipeline discharges the sewage smoothly, starting the steps.

Wherein, in the blockage removing process, the blowoff valve can be operated according to the following method to increase the blockage removing effect:

the first mode is as follows: before the action of the block cleaning valve, the blow-down valve is opened for a few times. And in the blockage clearing process, the switch is intermittently switched. The method specifically comprises the following steps: before the blockage clearing action, a downstream blow-down valve is opened, the opening degree is a 1% (a 1 is more than 0 and less than or equal to 100), and the downstream blow-down valve is closed after a certain time; then, in the process of clearing the blockage, opening a downstream blow-down valve with the opening degree of a 2% (a 2 is more than 0 and less than or equal to 100), and closing after a certain time; and finally, after the action of the blockage clearing valve is finished, opening the downstream blow-down valve, wherein the opening degree is a 3% (a 3 is more than 0 and less than or equal to 100), and closing the downstream blow-down valve after a certain time, so that the aim of clearing blockage is fulfilled and a certain amount of dirty liquid is discharged smoothly.

The second mode is as follows: before the blockage clearing action, the drain valve is opened, and is kept open in the blockage clearing process until the blockage clearing is finished.

A third mode: before the blockage cleaning action, the drain valve is not moved. In the process of clearing the blockage, the device starts to move, and is switched on and off intermittently in the blockage clearing process until the blockage clearing is finished.

A fourth formula: before the action of the block cleaning valve, the drain valve is not moved. The blockage removing process is started and kept open until the blockage removing is finished.
