The operating lever has one end pivotally connected to the fixed member and the other end having a handle, and further has a slide groove in which a pin fixed to the movable table moves.

The guide mechanism comprises 4 elongated members, the 4 members being divided into two groups, one group being 2, located on each side of the connector means, each two elongated members forming a pivotable connection at a central intersection and forming an X-shape; two ends of the 4 slender components are connected with pins, two side surfaces of the same end of the fixed component and the movable working platform are provided with horizontal grooves, and the pin connected with one end of the slender component can horizontally move in the horizontal grooves. When the operating rod is pivoted, the pin fixed on the movable workbench moves in the sliding groove on the operating rod, the pin connected to one end of the elongated member moves horizontally in the horizontal groove, the included angle between the two X-shaped elongated members is closed or opened, so that the movable workbench is guided to move upwards or downwards, and a plurality of joints penetrating through the lower surface of the fixing piece can be in sealing connection with or disconnected from corresponding pipe fittings of the filtering unit.

In this connection device, it is necessary to convert the pivotal movement of the operating lever into the horizontal movement of the pin, which in turn is converted into the vertical movement of the movable table and the filter. The above process involves two motion transformations, which require very precise control of the length of the elongated member, of the length of the horizontal slot of the fixed part and of the movable table, and of the external diameter of the pin located in the horizontal slot, i.e. higher requirements are placed on the manufacture of the components of the connection device, ensuring precise control of all the dimensional parameters, increasing the difficulty of manufacture.

Further, the guide mechanism has a large number of parts, and when assembling, the 4 elongated members are first connected by pins to form 2X-shaped forks, and then the 2X-shaped forks are connected by pins to the fixed portion and the movable table, respectively.

The driving assembly 4 is respectively connected with each side plate 14 through a pivot pin 12, the pivot pin 12 is arranged at one end part of the side plate 14 and the driving assembly 4, the extension direction of the pivot pin 12 is vertical to the movement direction of the supporting assembly 3, and when the other end part of the driving assembly 4 is far away from the fixing assembly 1, an opening 5 for mounting and dismounting the filtering unit 2 is formed between the driving assembly 4 and the fixing assembly 1.

Specifically, taking the direction shown in fig. 5 as an example, the pivot pin 12 is located at the lower end portions of the fixing component 1 and the driving component 4 and is located below the supporting component 3, taking the installation direction of the fixing component 1 as an example, the fixing component 1 is fixed in a pipeline, the driving component 4 is located right in front of an operator, the moving direction of the supporting component 3 is front and back, the extending direction of the pivot pin 12 is left and right, that is, the extending direction of the pivot pin 12 is perpendicular to the moving direction of the supporting component 3. When the driving member 4 rotates about the pivot pin 12 relative to the fixed member 1, the upper end of the driving member 4 is away from the fixed member 1, so that an opening 5 for mounting and dismounting the filter unit 2 is formed between one side of the fixed member 1 and the driving member 4. Because the opening 5 is positioned between one side of the fixed component 1 and the driving component 4, the axial height involved in the whole assembly process is greatly smaller than the sum of the axial heights of the filtering unit 2 and the fixed component 1, namely, the space occupied by the assembly process, particularly the space in the axial direction, can adapt to narrower installation environment, and has higher installation adaptability.

Further, one of the support member 3 and the side plate 14 has a guide projection 31, and the other has a guide groove 13, and the guide projection 31 is slidably inserted into the guide groove 13 to movably connect the support member 3 to the side plate 14. In the present embodiment, as shown in fig. 1 and 5, 2 guide protrusions 31 are fixed to opposite sides of the outer periphery of the support member 3, two side plates 14 each have one guide groove 13, and the 2 guide protrusions 31 are respectively inserted into the guide grooves 13 and can be relatively slid. Of course in other embodiments the guide projections 31 may be located in the side plates 14 and the guide slots 13 provided on the support assembly 3.

As shown in fig. 4, in order to ensure the stability of the guide projection 31, a stopper projection 311 is formed on the guide projection 31, and the stopper projection 311 is configured to abut against the opening edge of the guide groove 13. After the guide projection 31 is clamped into each guide groove 13, the limiting boss 311 is attached to the opening edge of the guide groove 13, so that the guide projection 31 can be stably matched with the guide groove 13, and the guide projection 31 is prevented from being separated or deviating.

As shown in fig. 1, 3 and 5, the guiding groove 13 at least includes a limiting section 131, and the limiting section 131 extends along a direction perpendicular to the axial direction of the filter unit 2, so that when the guiding protrusion 31 and the limiting section 131 slide relatively, the supporting assembly 3 and the filter unit 2 can be driven to move along the direction perpendicular to the axial direction of the filter unit 2, so that the first engaging section 111 and the second engaging section 211 form a sealing connection or separation. The length of the limiting section 131 is greater than or equal to the length of the sealing stroke of the first engaging section 111 and the second engaging section 211. When the guide projection 31 and the limiting section 131 of the guide groove 13 slide relative to each other, the support assembly 3 drives the filter unit 2 to move together in a direction perpendicular to the axial direction of the filter unit 2, so that the second engagement section 211 extending in the axial direction of the pipe 21 of the filter unit 2 is in sealing connection with or disconnected from the first engagement section 111 of the joint 11.

Wherein, during the sealing stroke of the second engagement section 211 extending axially of the tube 21 of the filter unit 2 and the first engagement section 111 of the joint 11, namely the end of the second engagement section 211 extending perpendicularly to the axial direction of the tube 21 of the filter unit 2 and the end of the first engagement section 111 of the joint 11 are just aligned to form a sealing connection, the tube 21 moves relative to the first engagement section 111 in the direction perpendicular to the axial direction, and the length of the limiting section 131 extending perpendicularly to the axial direction is not less than the displacement, so that the axial height of the filter unit 2 is constant during the process that the second engagement section 211 extending perpendicularly to the axial direction of the tube 21 and the first engagement section 111 of the joint 11 form a sealing connection, and the second engagement section 211 extending axially of the tube 21 and the first engagement section 111 of the joint 11 are aligned, and after the installation, an axial press with enough strength is formed on a sealing ring installed between the two, thereby forming a sealed connection.

In other embodiments, as shown in fig. 8, the guiding slot 13 further includes a guiding section 132 extending obliquely to the axial direction and located on a side of the limiting section 131 far from the joint 11. The guide section 132 can reduce the resistance of the guide projection 31 and the guide groove 13 to sliding relative to each other, thereby making the operation of the driving assembly 4 more labor-saving. When the guide projection 31 slides relative to the guide section 132, the movement direction of the support member 3 is inclined relative to the axial direction. However, during the sealing stroke of the first engaging section 111 and the second engaging section 211, i.e. the stroke of the corresponding limiting section 131, the support assembly 3 and the filter unit 2 move in a direction perpendicular to the axis of the filter unit 2.

As shown in fig. 4 and 5, the driving assembly 4 and the supporting assembly 3 are connected by a link 32, and when the driving assembly 4 performs a pivoting motion relative to the side plate 14, the driving assembly drives the link 32 to generate a pushing action on the supporting assembly 3 so as to push the guide projection 31 and the guide groove 13 to slide relatively, and the supporting assembly 3 moves towards a direction close to or away from the joint 11, so that the overall structure is stable and effective in matching. Specifically, one end of the connecting rod 32 is connected to the guiding protrusion 31, and a shaft 34 passes through the guiding protrusion 31 and the connecting rod 32 to connect with the supporting component 3.

The driving assembly 4 includes a driving arm 41, the driving arm 41 including a driving section 411 and a connecting section 412 integrally connected, the connecting section 412 and the side plate 14 being connected by a pivot pin 12, the driving section 411 being connected to one end of the connecting rod 32. The number of the driving arms 41 is two, and the two driving segments 411 are connected into a whole by a connecting arm 413. 2 lateral plates 14 are respectively attached to 2 driving arms 41, so that stable rotation between the driving assembly 4 and the fixing assembly 1 is ensured. The above-mentioned guide projections 31 and guide grooves 13 are provided between the two side plates 14 and the opposite sides of the periphery of the support member 3; the connecting arms 413 and the fixing plate 15 are located on opposite sides of the side plate 14. In other words, taking the orientation shown in fig. 5 as an example, the connecting arm 413 is located on the right side of the side plate 14, and the fixing plate 15 is located on the left side of the side plate 14. The two driving arms 41 are respectively located at two sides of the side plate 14 and are attached to the side plate, so that the movement stability of the driving arms 41 is ensured, and the stability of the driving assembly 4 during the pivoting motion relative to the side plate 14 is also ensured.

A support 17 is formed at the axially lower end inside the side plate 14 for supporting the filter unit 2, and a gap 16 for accommodating a pipe 21 is formed between the two support 17. The supporting part 17 is used for forming a gap to provide a containing space for the pipe fitting 21 of the filtering unit 2 while ensuring that the filtering unit 2 is stably supported, and the structural design is reasonable.

As shown in fig. 4 to 7, the support member 3 has a mounting groove 33 extending downward in the axial direction from the upper axial end of the support member 3, and a mounting projection 22 matching the mounting groove 33 is provided on the outer wall of the filter unit 2, the mounting projection 22 being located on the outer surface of the housing 20. When the fitting projection 22 is inserted into the fitting groove 33, the filter unit 2 is restrained in the support member 3, i.e., the filter unit 2 is not moved up and down and shifted left and right. Mounting groove 33 and installation lug 22 cooperation have guaranteed filter element 2 spacing, prevent that filter element 2 axial from breaking away from supporting component 3, or relative supporting component 3 takes place and controls the skew, and whole assembly stable in structure.

Specifically, the supporting member 3 includes a supporting body 35 penetrating up and down, the mounting groove 33 is a U-shaped groove with an opening at the top of the supporting body 35, and the guiding protrusion 31 or the guiding groove 13 is disposed below the mounting groove 33. In the present embodiment, the support body 35 has a C-shape, and the opening thereof faces the side of the fixing member 1 where the joint 11 is located, and more specifically, the opening of the support body 35 faces the fixing plate 15. The C-shaped support body 35 enables the inner diameter of the support body 35 to be expanded and contracted in a small range so as to adapt to the filter units 2 with different outer diameters, and the assembly adaptability is high. The support body 35 is vertically penetrated to facilitate the insertion or extraction of the filter unit 2.

In addition, in order to facilitate the assembly and disassembly of the filter unit 2 and reduce the axial space occupied by the assembly and disassembly of the filter unit 2, the support assembly 3 can rotate relative to the side plate 14. Supporting component 3 can rotate for curb plate 14 relatively for supporting component 3 can incline for curb plate 14 relatively, be convenient for taking out or putting into of filter unit 2, especially filter unit 2 can incline and take out or put into, and the dismouting is more convenient, and has reduced the shared axial space of filter unit 2 dismouting.

In addition, as shown in fig. 6, the present application provides a filter unit 2 including a housing 20 and a filter element (not shown) inside the housing 20, the housing 20 having at least 2 pipe members 21, and the pipe members 21 communicating with the inside of the housing 20. More specifically, one of them communicates with the space between the inner wall of the housing 20 and the outer periphery of the filter element as a raw material liquid inlet, and the other communicates with the inside of the filter element as a clean filtrate outlet. In this embodiment, there are 3 pipe members 21, and the third pipe member 21 is also communicated with the space between the inner wall of the housing 20 and the outer periphery of the filter element as an air outlet.

Each pipe member 21 has a second coupling section 211 perpendicular to the axial direction of the filter unit 2 and an extension section 212 parallel to the axial direction of the filter unit 2, the extension section 212 being integrally formed at an end of the housing 20, one end of which is connected to an end of the housing 20 and the other end of which is connected to the second coupling section 211. The extension section 212 and the second engagement section 211 are integrally formed, and each pipe 21 is located at an end of the housing 20. The pipe members 21 are provided at both ends of the housing 20, respectively, and 2 pipe members 21 as an exhaust port and a clean filtrate discharge port are provided at an upper end in the axial direction of the housing 20, and a raw material liquid inlet is provided at a lower end in the axial direction of the housing 20.

The filter unit 2 is detachably fixed to the fixing device, specifically, the filter unit 2 is detachably fixed to the supporting component 3, and when the driving component 4 performs a pivoting motion relative to the fixing component 1, the supporting component 3 and the filter unit 2 can be pushed to move along an axial direction perpendicular to the filter unit 2 to be close to or far away from the joint 11 of the fixing component 1, so that the second engaging section 211 can be in sealing connection with or separated from the first engaging section 111 of the joint 11.

Of course, the pipe member 21 may also include only the second engagement section 211 perpendicular to the axial direction of the filter unit 2 without the extension section 212 described above, in which case the at least 2 pipe members 21 are provided on the side wall of the housing 20. The filter unit 2 is moved in a direction perpendicular to the axial direction, and when approaching the joint 11, the second engagement section 211 of the pipe member 21 on the side wall of the housing 20 also forms a sealing connection with the first engagement section 111 of the joint 11.

As shown in fig. 9, the filter unit 2 is installed by rotating the driving component 4 clockwise relative to the fixing component 1 until an opening 5 is formed between one side of the fixing component 1 and the driving component 4, and axially placing the filter unit 2 into the supporting component 3 until the installation bump 22 completely falls into the installation groove 33, at which time the joint 11 on the fixing component 1 is opposite to the pipe 21 on the filter unit 2; then, an external force is applied to rotate the driving assembly 4 counterclockwise relative to the fixed assembly 1, and the guiding protrusion 31 is translated in the guiding groove 13 in a direction close to the fixed plate 15, i.e. the supporting assembly 3 and the filter unit 2 are pushed close to the joint 11, and the first engaging segment 111 and the second engaging segment 211 are translated relatively to form a sealing connection.

Of course, in the case that the supporting component 3 can rotate relative to the fixing component 1, the supporting component 3 can be tilted relative to the fixing component 1, then the filtering unit 2 can be tilted and fixed to the supporting component 3, and then the supporting component 3 can be rotated, so that the supporting component 3 and the filtering unit 2 are parallel to the fixing component 1.

The present application further provides a filtration system comprising,

a filter unit 2 having at least two pipe members 21, the pipe members 21 forming a second coupling section 211 perpendicular to an axial direction of the filter unit 2;

the supporting component 3 is movably connected with the fixing component 1 and is used for fixing the filtering unit 2;

a driving component 4 which is pivoted to the fixed component 1 from the axial lower part of the supporting component 3 and is movably connected with the supporting component 3;

application of an external force to cause pivotal movement of the driving assembly 4 relative to the fixing assembly 1 can push the support assembly 3 and the filter unit 2 to move in an axial direction perpendicular to the filter unit 2 to approach or separate from the joint 11, so that the first engaging section 111 and the second engaging section 211 form a sealed connection or separation.

The specific structures of the fixing assembly 1, the filtering unit 2, the supporting assembly 3, and the driving assembly 4 are the same as those described above, and are not described again.
