Technical Field

Background

At present, a pipeline cleaning machine is generally used in the industry for cleaning an internal circulation pipeline of the equipment, and is limited by the structure of the cleaning machine, and most of the existing cleaning machines generally adopt a circulating chemical pickling method and a water-gas mixed flushing method; the circulating chemical acid washing method can effectively remove scales, deposited sands, rusty spots and the like, but has high use cost (depending on the cost of chemical reagents), is easy to pollute the environment, and has certain safety risks (for example, once the chemical reagents leak and contact the skin, the skin can be itchy, or the eyes of operators can be easily damaged); the water-gas mixed flushing method has the problems of unclean pipeline cleaning, incapability of removing firm water scale or rust spots, long cleaning period and the like. Meanwhile, in order to ensure the smooth completion of the cleaning operation of the circulating pipeline, the tightness of the circulating pipeline can be tested before the cleaning operation, a common mode in the industry is to adopt a hand pressure pump or an electromotive force pressure pump to be connected with the circulating pipeline and use a pressure gauge to visually inspect and judge whether the pipeline has a leakage point, and due to the existence of phenomena such as pipeline blockage, the mode can not accurately detect whether the pipeline is unblocked or whether the pipeline reaches the sealing standard, and once the problems such as pipeline blockage occur, the pipeline needs to be cleaned and then sealed and tested again, and the process is repeated, so that the period of the pipeline processing operation is greatly increased; in addition, the independent use of the sealing test equipment and the cleaning equipment also increases the complexity of pipeline treatment and the acquisition cost of the equipment, and reduces the working efficiency. In view of this, there is a need for improvements to existing cleaning equipment.

Therefore, when the cleaning machine of the embodiment is actually used, the related operations can be executed in the following manner, specifically: 1. performing sealing test operation, namely butting the two ends of the workpiece circulating pipeline with a first test on-off connecting pipe E21 and a second test on-off connecting pipe E22, and performing switching control on a water filling water pump B2 and a one-inlet multi-outlet type electromagnetic integrated valve group and on-off switching between corresponding pipelines by using a system centralized control assembly to realize operation procedures of water filling, pressurization, pressure maintaining and the like on the workpiece circulating pipeline; in the process, the pressure of the pipeline is detected in real time by using the test pipeline pressure sensor G21, so that the condition of the pipeline can be obtained by the system centralized control assembly through comparison with a preset threshold value. 2. And (3) cleaning the pipeline, according to the detection result of the sealing test operation, butting the two ends of the workpiece circulating pipeline with a first cleaning on-off connecting pipe E11 and a second cleaning on-off connecting pipe E12 under the condition that the pipeline is unblocked, and performing switching control on a cleaning water pump B1 and a large-flow electromagnetic switch valve D109 and on-off switching between corresponding pipelines by using a system centralized control assembly, so that the working procedures of high-pressure flushing, high-pressure steel shot mixed flushing, exhaust air drying and the like of the workpiece circulating pipeline can be realized, and the cleaning effect is effectively ensured.

In order to ensure the cleaning effect of the workpiece circulating pipeline, in particular to realize the bidirectional high-pressure steel ball mixed flushing operation of the pipeline, the waterway cleaning assembly of the embodiment also comprises a second steel ball shot storage barrel Q12 which has the same structure with the first steel ball shot storage barrel Q11, a fluid inlet of the second steel ball shot storage barrel Q12 is communicated with a fluid inlet of the first steel ball shot storage barrel Q11 through a pneumatic three-way valve K111 and a water outlet of a backwater material separation tank H1, a steel ball outlet is communicated with a second connecting pipe E12 for cleaning, a backwater water outlet is communicated with a backwater port of a cleaning water storage tank T1, a high-pressure drainage port is communicated with a water outlet of a cleaning water pump B1 in an on-off mode, and a pneumatic three-way valve K111 is communicated with a one-inlet multi-outlet type electromagnetic integrated valve group (specifically, the on-off control of two air outlets can be realized by a first three-way electromagnetic valve D103 for cleaning on the valve group); wherein, the first cleaning on-off connecting pipe E11 and the second cleaning on-off connecting pipe E12 are respectively in on-off communication with the downstream of the cleaning water path one-way valve F11, the downstream of the cleaning air path one-way valve F12 and the water return port of the backwater material separating tank H1.

Therefore, a parallel pipeline network which can be communicated and converted is formed at the water outlet end of the cleaning water pump B1 and the water inlet end of the backwater substance separating tank H1 by the second steel ball pill storage barrel Q12 and the corresponding devices through the communication relation between the corresponding devices and the first steel ball pill storage barrel Q11 and the on-off connecting pipe, when the workpiece circulating pipeline is positively flushed, after water conveyed by the cleaning water pump B1 is mixed with steel balls conveyed by the first steel ball pill storage barrel Q11, flows back to the backwater substance separation tank H1 via the first on-off connection pipe for cleaning E11, the workpiece circulation pipe and the second on-off connection pipe for cleaning E12 to separate impurities and steel balls, wherein, the impurities are retained in the backwater substance separating tank H1, the steel balls enter the second steel ball pill storage barrel Q12, and most of water flows back to the cleaning water storage tank T1 through the backwater substance separating tank H1 and the second steel ball pill storage barrel Q12; when the steel ball storage amount in the second steel ball storage barrel Q12 exceeds the upper limit value or the steel ball storage amount in the first steel ball storage barrel Q11 is lower than the lower limit value, the system centralized control assembly can output the steel balls from the second steel ball storage barrel Q12 through the switching control of the pneumatic three-way valve K111 and the on-off switching of corresponding pipelines, so that the reverse flushing operation is executed, and the cleaning effect on the pipelines can be ensured by reciprocating in this way; after the cleaning operation is finished, the large-flow electromagnetic switch valve D109 is started to inflate the workpiece circulation pipeline, so that residual accumulated water is discharged by utilizing gas.

In order to ensure the reaction speed of the waterway cleaning assembly when the operation mode is converted and improve the intelligent control effect of the machine, the steel shot flow outlet of the first steel ball shot storage barrel Q11 is in on-off communication with a first cleaning on-off connecting pipe E11 through a first electric proportional control valve M11 and a ninth pneumatic ball valve K109 which are sequentially arranged, the high-pressure drainage port is in on-off communication with the water outlet of a cleaning water pump B1 through a first differential pressure solenoid valve D101, the backwater water outlet is in on-off communication with the backwater port of a cleaning water storage tank T1 through a sixth pneumatic ball valve K106, the steel shot flow outlet of the second steel ball shot storage barrel Q12 is in on-off communication with a second cleaning on-off connecting pipe E12 through a second electric proportional control valve M12 and a tenth pneumatic ball valve K110 which are sequentially arranged, the high-pressure drainage port is in on-off communication with a cleaning water pump D102 through a second differential pressure solenoid valve D102, and the backwater water outlet is in on-off communication with the backwater port of a cleaning water storage tank T36; the first electric proportional control valve M11, the second electric proportional control valve M12, the first differential pressure solenoid valve D101 and the second differential pressure solenoid valve D102 are respectively in control connection with the system centralized control assembly, and the fifth pneumatic ball valve K105, the sixth pneumatic ball valve K106, the ninth pneumatic ball valve K109 and the tenth pneumatic ball valve K110 are respectively communicated with the one-inlet-multiple-outlet type electromagnetic integrated valve group (the on-off control can be realized by specifically utilizing the first three-way solenoid valve D103 for cleaning, the second three-way solenoid valve D104 for cleaning, the third three-way solenoid valve D105 for cleaning and the like on the valve group).

In order to ensure that the steel balls flowing back to the backwater substance separation tank H1 can be smoothly recovered into the corresponding pill storage barrel, the water outlet of the backwater substance separation tank H1 of the present embodiment is also in on-off communication with the water outlet of the cleaning water pump B1 through the first electromagnetic cleaning switch valve D106. Therefore, water which is shunted by the water outlet of the cleaning water pump B1 can directly enter the backwater material separating tank H1, so that the material (especially steel balls) accumulated in the backwater material separating tank H1 can smoothly enter the corresponding pill storage barrel by utilizing the flushing effect of the water flow. Certainly, in order to ensure the separation effect of the backwater substance separation tank H1 on the components of the mixed fluid, as shown in fig. 11, the backwater substance separation tank H1 of this embodiment includes a backwater tank body H11, a specific gravity baffle H14 disposed in the backwater tank body H11 to separate the tank body space of the backwater tank body H11 into a steel shot collecting tank H12 and an impurity filtering tank H13 which are mutually distributed in parallel, and a steel ball filtering funnel H15 disposed at the bottom of the steel shot collecting tank H12 and used as a water outlet of the backwater substance separation tank H1; meanwhile, a water inlet of the backwater substance separation tank H1 is arranged in the steel shot collecting tank H12, the impurity filtering tank H13 is connected with a backwater port of the water storage tank T1 for cleaning, and an upper limit steel ball induction switch (not shown in the figure) connected with a system centralized control assembly is further arranged on the backwater tank body H11 and positioned at the upper end of the steel ball filtering building funnel H15. Therefore, in the actual use process of the system, because the mixed fluid discharged from the workpiece circulating pipeline mainly comprises water, steel balls and impurities (such as settled sand, rusty spots, water scales and the like), the characteristics of density difference between the water, the steel balls and the impurities can be utilized to separate the two components through the specific gravity baffle plate H14, namely: after the mixed fluid enters the steel ball collecting tank H12, the steel balls sink into the steel ball filter funnel H15 due to the fact that the density of the steel balls is larger than that of water, and finally enter the ball storage barrel along with water flow, impurities floating on the water are shunted to the impurity filter tank H13 along with the water flow through the specific gravity baffle H14, at the moment, a corresponding filter screen can be arranged in the impurity filter tank H13, the impurities are deposited on the filter screen, and therefore the effect of separating the complete substances is achieved.

In order to realize effective on-off control of water inlet or water outlet of the on-off connecting pipe for cleaning, the first on-off connecting pipe E11 for cleaning of the embodiment is simultaneously in on-off communication with the downstream of the one-way valve F11 for cleaning and the downstream of the one-way valve F12 for cleaning through a first pneumatic ball valve K101 and is in on-off communication with the water return port of the backwater material separating tank H1 through a second pneumatic ball valve K102, and the second on-off connecting pipe E12 for cleaning is simultaneously in on-off communication with the downstream of the one-way valve F11 for cleaning and the downstream of the one-way valve F12 for cleaning through a fourth pneumatic ball valve K104 and is in on-off communication with the backwater material separating tank H1 through a third pneumatic ball valve K103; the first pneumatic ball valve K101, the second pneumatic ball valve K102, the third pneumatic ball valve K103 and the fourth pneumatic ball valve K104 are respectively communicated with a one-inlet-multiple-outlet type electromagnetic integrated valve group (specifically, on-off control can be realized by using a first three-way electromagnetic valve D103 for cleaning on the valve group).

In addition, in order to ensure that the whole waterway cleaning assembly can simultaneously perform simultaneous operation on multiple workpiece circulation pipelines and enrich the function of the whole assembly, the first on-off connecting pipe E11 for cleaning in the present embodiment can be specifically designed with reference to fig. 8 to 10, that is: the air injection valve assembly comprises a second channel current collection block E101, a driving cylinder assembly E102 and a plurality of (such as four) air injection valves E103, wherein the second channel current collection block E101 is of a cuboid structure in the whole shape, the driving cylinder assembly E102 is arranged on the left side wall or the right side wall of the second channel current collection block E101, and outputs power along the front-back direction of the second channel current collection block E101, and the air injection valves E103 are arranged on the rear side wall of the second channel current collection block E101 and are arranged in a vertical side-by-side mode; a second water channel E104 which is distributed along the vertical direction and one end of which is communicated with the downstream of the cleaning water channel one-way valve F11, a cylinder opening air channel E105 which is communicated with an opening chamber of the driving cylinder assembly E102, a cylinder closing air channel E106 which is communicated with a closing chamber of the driving cylinder assembly E102 and a plurality of second fluid circulation channels E107 which are communicated with the second water channel E103 and are positioned at the front end side of the second channel flow collecting block E101 are arranged in the second channel flow collecting block E101, and a second fluid nozzle E108 is arranged in each second fluid circulation channel E107 in a penetrating way; wherein, the second fluid flow channel E107 corresponds to the air injection valve E103 one by one (namely: each second fluid flow channel E107 and the corresponding second fluid nozzle E108 has an air injection valve E103 in one-to-one alignment, the body of each air injection valve E103 is arranged on a power shaft of the driving cylinder assembly E102, a valve core penetrates through a corresponding second fluid nozzle E108 through a second water channel E104, and an air inlet of each air injection valve E103 is communicated with an air outlet of the air storage tank P through a second electromagnetic switch valve D107 for cleaning and a valve pressure sensor G15; correspondingly, the cylinder opening air passage E105 and the cylinder closing air passage E106 are both communicated with the one-inlet and multi-outlet type electromagnetic integrated valve group, and on-off control can be realized by a fourth three-way electromagnetic valve D108 for cleaning on the valve group; of course, the second opening/closing connection pipe E12 for washing may have substantially the same or simplified structure as that of the first opening/closing connection pipe E11 for washing.

Therefore, the second fluid nozzle E108 and the second water channel E104 can be isolated by using the inserting and sleeving relation between the valve core (which may adopt a structure similar to a tube) of the air injection valve E103 and the second fluid nozzle E108, and the second water channel E104 and the second fluid nozzle E108 can be conducted after the valve core is drawn away from the second fluid nozzle E108; when the ventilation detection is carried out on the workpiece circulating pipeline, a system centralized control assembly can be used for opening a pipeline which flows back to a cleaning water storage tank T1 or a backwater material separation tank H1 through a cleaning second on-off connecting pipe E12 in advance, then the gas injection valve E103 is inflated through the opening of a cleaning second electromagnetic switch valve D107, compressed gas enters the workpiece circulating pipeline through a valve core and a second fluid nozzle E108, and in the process, the gas pressure can be detected in real time through a valve pressure sensor G15, so that data support is provided for judging whether the workpiece circulating pipeline is blocked or not; when the pipeline is flushed, the driving cylinder assembly E102 is opened by the control of the system centralized control assembly on the fourth three-way electromagnetic valve D108 for cleaning, so that the driving cylinder assembly E102 can drive the gas injection valve E103 to move backward relative to the second channel manifold block E101, and the valve core is pulled away from the second fluid nozzle E108 to communicate with the second water channel E104, thereby performing the flushing operation.

Therefore, when the workpiece circulating pipeline is pressurized, water remained in a water cavity in the gas-liquid pressure cylinder Z21 can be conveyed into the workpiece circulating pipeline through charging the air into the forward cavity of the gas-liquid pressure cylinder Z21 so as to be pressurized completely, in the process, the pressurized pressure can be stably increased by storing compressed air through the buffer gas bottle Z22, and when the pipe pressure detected by the test pipeline pipe pressure sensor G21 reaches the upper limit value, the backward cavity of the gas-pressure cylinder Z2 can be charged through controlling the one-inlet and multi-outlet type electromagnetic integrated valve group (specifically, the test second three-way electromagnetic valve D203), so that the pipeline pressurizing operation is finished.

In order to enable the system mode of the whole assembly to be rapidly changed, a first test on-off connecting pipe E21 is in on-off communication with the downstream of a test waterway one-way valve F21 through a first pneumatic stop valve C21, a second test on-off connecting pipe E22 is in on-off communication with the water inlet of a test backwater filter tank H2 through a second pneumatic stop valve C22, the first pneumatic stop valve C21 and the second pneumatic stop valve C22 are simultaneously communicated with a multi-inlet electromagnetic integrated valve group (on-off control can be realized by a first test three-way electromagnetic valve D202 on the valve group), and the first pneumatic stop valve C21 is in on-off communication with the air outlet of an air storage tank P through a first test electromagnetic switch valve D201 between the first pneumatic stop valve C21 and the test waterway one-way valve F21. Therefore, the system centralized control assembly can indirectly control the first pneumatic stop valve C21 and the second pneumatic stop valve C22 by controlling the first three-way electromagnetic valve D202 for testing, and can quickly utilize compressed gas to synchronously open or close the first pneumatic stop valve C21 and the second pneumatic stop valve C22 when the first three-way electromagnetic valve D202 for testing is opened; meanwhile, when the pneumatic cutoff valve is closed, the first electromagnetic opening/closing valve D201 for testing may be used to directly vent the inside of the workpiece circulation pipe to previously test whether the pipe is completely blocked.

Therefore, the system centralized control assembly can be used for controlling the opening and closing of the priming water pump B3 in pairs, water which is stored in the universal water storage tank T3 and mixed with a descaling agent is conveyed into a workpiece circulating pipeline through the universal first priming on-off connecting pipe E31, impurities are separated from the inner wall of the pipeline through the chemical reaction of the descaling agent and the impurities in the pipeline, so that the pipeline is dredged, and then the impurities flow back into the universal water return filter tank H3 through the universal second priming on-off connecting pipe E32 to be filtered (the filtered impurities can be manually taken out from the water return filter tank, and the rest fluid flows back into the universal water storage tank T3 to be continuously used); in the process, the universal waterway one-way valve F31 for filling is utilized to avoid the backflow of fluid when the workpiece circulating pipeline is seriously blocked, thereby providing conditions for the chemical reaction between the descaling agent and impurities; meanwhile, the universal filling air path check valve F32 and the universal filling first electromagnetic switch valve D301 can be used for ventilating or draining the pipeline when the water path filling assembly performs operation. In practical application, especially before cleaning the work piece circulating line, the system can be utilized to dredge the seriously blocked water way so as to form a flow channel with a certain aperture in the pipeline and for the steel balls to pass through, thereby providing convenience for the follow-up steel ball mixed flushing operation and avoiding the problems of failure of cleaning operation and the like caused by directly cleaning the workpiece circulating line when the workpiece circulating line is seriously blocked.
