Description

Technical Field

[0001] The present application relates to the technical field of mining equipment, and in particular to a temporary filtration device for a branch line dedicated to a gold mine. Background Art

[0002] In the process of gold mining, slurry filtration is a key step, which directly affects the efficiency and effect of the subsequent purification and concentration process. A large amount of gold-containing solid waste will be generated during the extraction and preliminary processing of the ore. These wastes often contain a certain amount of recyclable gold particles or other valuable metals. If they are directly discarded, it will cause a waste of resources. Therefore, it is necessary to further extract the valuable components through sorting and filtration.

[0003] In the prior art, a gold mine filtering device comprises a main pipeline, a main valve is arranged on the main pipeline, and a filtering system for filtering the ore pulp is arranged on the main pipeline.

[0004] However, existing filtration systems are usually designed for continuous operation and lack flexibility. When workers need to inspect or maintain the equipment, they often need to stop the entire production line. They are unable to quickly adapt to temporary changes in the ore processing process or small-scale branch processing needs, which not only affects production efficiency, but may also lead to waste of resources and economic losses. Summary of the invention

[0005] In order to carry out equipment inspection and maintenance without affecting the operation of the production line, thereby improving production continuity and production efficiency, and further improving the economic benefits of the enterprise, the present application provides a temporary branch filtering device for gold mines.

[0006] The present application provides a temporary filtration device for gold mines using the following technical solution:

[0007] A temporary filtration device for branch lines dedicated to gold mines, comprising a main pipeline, the main pipeline being connected to a secondary pipeline, the secondary pipeline being provided with a valve, the secondary pipeline being provided with a multi-stage filtration mechanism for filtering slurry, the multi-stage filtration mechanism comprising a plurality of filter plates, the filter holes on the plurality of filter plates having different aperture sizes, the plurality of filter plates being sequentially installed in the secondary pipeline along the length direction of the secondary pipeline according to the different aperture sizes of the filter holes; the ends of the filter plates sliding horizontally on the inner wall of the secondary pipeline, the multi-stage filtration mechanism comprising a plurality of groups of vibration components for driving the filter plates to vibrate; the multi-stage filtration mechanism further comprising a scraper and a first drive component for driving the scraper to rotate, the scraper being arranged in the secondary pipeline and rotatably arranged on the surface of the filter plate.

[0008] By adopting the above technical solution, when the filtering system or equipment on the main pipeline needs to be repaired, the main valve on the main pipeline can be closed first, and then the valve on the secondary pipeline can be opened. At this time, the slurry can flow in the secondary pipeline, and the multi-stage filtering mechanism arranged in the secondary pipeline can temporarily filter the slurry. The multi-stage filtration can gradually remove particles of different sizes, and each stage is aimed at a specific particle size, thereby improving the overall filtration efficiency; at the same time, pre-filtration can intercept larger particles, reduce the wear on subsequent filter media, and extend its service life; the whole process is convenient for staff to carry out equipment inspection and maintenance without affecting the operation of the production line, thereby improving production continuity and production efficiency, and then improving the economic benefits of the enterprise; when the slurry flows normally in the secondary pipeline, the vibration component can drive the filter plate to vibrate, and the first drive component can drive the scraper to rotate, thereby reducing the risk of filter plate clogging.

[0009] Preferably, multiple groups of the vibration components are arranged corresponding to the multiple filter plates; the vibration components include a motor, a push plate and a connecting rod, the motor is installed on the side wall of the auxiliary pipe; the push plate slides on the auxiliary pipe, and the push plate abuts against the filter plate; a rotating plate is fixedly arranged on the motor shaft, a sliding block is arranged on the push plate, universal joints are installed on the rotating plate and the sliding block, and the two ends of the connecting rod are respectively fixedly connected to the ball heads on the two universal joints; a spring 1 is arranged in the auxiliary pipe, and the two ends of the spring 1 are respectively fixedly arranged on the filter plate and the inner wall of the auxiliary pipe.

[0010] By adopting the above technical solution, when the slurry flows normally in the auxiliary pipeline, the staff can turn on the motor, the motor can drive the rotating plate to rotate, and the rotating plate can drive the universal joint on it to rotate. At this time, the end of the connecting rod close to the rotating plate rotates with the rotating plate. Due to the continuous change of the position of the universal joint on the rotating plate, the distance between the universal joint on the rotating plate and the universal joint on the slider is also constantly changing. Therefore, the connecting rod can rotate with the rotating plate and continuously drive the slider and the push plate to move back and forth. The push plate can push the filter plate to move, and the spring 1 is continuously squeezed and stretched. At this time, the filter plate can continuously vibrate under the push of the push plate and the elastic force of the spring 1, thereby helping the filter plate to separate solid particles and liquids faster and improve the overall filtration speed; at the same time, vibration can prevent excessive accumulation of solid particles on the surface of the filter medium and reduce the risk of clogging; in addition, since the clogging of materials and the frequency of replacement of the filter medium can be reduced, the maintenance cost is reduced.

[0011] Preferably, the first driving assembly includes a belt 1, a telescopic rod and two rollers 1, wherein one of the rollers 1 is fixedly arranged on the rotating shaft of the motor, and the other roller 1 is rotatably arranged in the auxiliary pipe, and the belt 1 is transmitted through the two rollers 1; the telescopic rod is arranged in the auxiliary pipe, and one end of the telescopic rod is fixedly arranged on the roller 1, and the other end of the telescopic rod is fixedly arranged on the scraper, and the first driving assembly includes a rotating part for driving the scraper to rotate.

[0012] By adopting the above technical solution, the motor can drive roller one to rotate in the process of driving its rotating shaft to rotate. At this time, belt one can be transmitted through two rollers, thereby driving another roller one to rotate, and the other roller one can drive the telescopic rod to rotate. The telescopic rod can be continuously stretched and contracted following the reciprocating movement of the filter screen, so that the scraper can always fit the surface of the filter plate. The driving member can drive the scraper to rotate while the telescopic rod rotates. The rotation of the scraper can remove solid particles on the surface of the filter plate and prevent the filter plate from being blocked due to the accumulation of solid particles, thereby improving the filtration efficiency. At the same time, it can also reduce the wear of the filter plate on the solid particles and extend its service life.

[0013] Preferably, a sealing box is provided before the filter plate of the secondary pipeline, a hose is provided in the sealing box, and two ends of the hose are respectively connected to ports of the secondary pipeline at two ends.

[0014] By adopting the above technical solution, when there are many solid particles accumulated in the auxiliary pipeline, the filter plate will be blocked, resulting in an increase in pressure in the upstream part of the auxiliary pipeline. The hose usually has a certain expansion capacity. When the liquid in the pipeline increases, the hose can expand to adapt to the pressure change, thereby reducing the pressure impact on other parts of the pipeline system; the hose set at the same time can reduce noise and structural stress; at the same time, the hose can adapt to the expansion or contraction of the pipeline caused by the liquid flow, maintaining the integrity of the pipeline system; the hose can distribute the pressure more evenly and reduce the pressure concentration in local areas of the pipeline system.

[0015] Preferably, a driving plate is provided in the sealing box for sliding movement, the driving plate abuts against the outer wall of the hose, a sliding plate is provided on the secondary pipe for horizontal sliding movement, two rollers 2 are rotatably provided on the sliding plate, the sliding block slides vertically on the push plate, a lead screw is rotatably provided on the push plate, the sliding block is threadedly engaged with the lead screw, one end of the lead screw is fixedly provided on one of the rollers 2, and a guide member for guiding the sliding block is provided on the push plate; a threaded rod is provided for vertical sliding movement in the sealing box, one end of the threaded rod is in contact with the driving plate and slides horizontally on the driving plate, the threaded rod is threadedly engaged with the other roller 2, a belt 2 is provided on the sliding plate, and the belt 2 is transmitted through the two rollers 2; a return spring is provided on the sliding plate, and both ends of the return spring are respectively fixedly provided on the threaded rod and the sliding plate.

[0016] By adopting the above technical solution, when the filter plate is blocked, the hose expands, and at this time the hose can push the drive plate to move, and the drive plate can push the threaded rod to move vertically, and the threaded rod drives one of the rollers 2 to rotate, and the roller 2 drives the other roller 2 to rotate through the belt 2, and the other roller 2 drives the lead screw to rotate, and the lead screw drives the slider to move, thereby changing the distance between the universal joint on the slider and the universal joint on the rotating plate, so that the distance between the universal joint on the slider and the universal joint on the rotating plate is increased, and then the movement amplitude of the push plate is increased, and the vibration amplitude of the filter plate is increased, which further reduces the possibility of blockage of the filter plate, improves the filtration efficiency of the filter plate, and thus helps to alleviate the local pressure of the auxiliary pipeline.

[0017] Preferably, the bottom of the auxiliary pipeline located before each of the filter plates is connected to a dredging pipe, a through hole is provided on the side wall of the auxiliary pipeline, the through hole is connected to the dredging pipe, and the outlet of the dredging pipe is connected to a collecting box; a sealing plate is rotatably arranged at the through hole, a sliding limit block is provided on the side wall of the auxiliary pipeline, and a limit groove is provided on the side wall of the sealing plate for the limit block to be plugged in; the valve is a gate valve, and a control component for controlling the movement of the gate plate in the gate valve is provided on the auxiliary pipeline; a second driving component for driving the limit block to move is provided on the auxiliary pipeline.

[0018] By adopting the above technical solution, when the slurry in the pipeline flows normally, the sealing plate is in a closed state, and the limit block is inserted into the limit groove on the sealing plate. When the pressure in the auxiliary pipeline continues to increase, the control component can be triggered, and the control component can first drive the gate plate in the gate valve to close. During the closing process of the gate plate in the gate valve, the second drive component can be triggered, and the second drive component can drive the limit block to move to a position away from the sealing plate. Then the sealing plate can be rotated to open, and the slurry in the auxiliary pipeline can flow out from the dredging pipe to the collection box, thereby reducing the accumulated solid particles in the pipeline, reducing the possibility of the filter plate being blocked, and then reducing the pressure in the pipeline.

[0019] Preferably, the second driving assembly includes a driving rod and an abutting rod, the driving rod slides on the side wall of the secondary pipeline, one end of the limit block is fixedly arranged on the driving rod, one end of the abutting rod is fixedly arranged on the driving rod, the abutting rod slides in the side wall of the secondary pipeline, and the abutting rod is provided with an inclined surface on the side close to the gate valve, a push block is hinged on the side wall of the gate plate in the gate valve, a stop block is arranged above the push block, the stop block is fixedly arranged on the gate plate in the gate valve, and the abutting rod is slidably matched with the push block through the inclined surface; the second driving assembly also has a reset component for resetting the driving rod.

[0020] By adopting the above technical solution, the gate plate in the gate valve can drive the push block to move during the closing process. When the gate plate in the gate valve is gradually closed, the push block can contact the abutment rod and push the abutment rod to move through the inclined surface on the abutment rod. At this time, the push block abuts on the stop block and the push block does not rotate. The abutment rod can drive the drive rod to move in the direction away from the auxiliary pipeline, and the drive rod drives the limit block to move in the direction away from the sealing plate, thereby reducing the difficulty of moving the limit block; then the gate plate in the gate valve continues to move, and when the push block moves to a position away from the abutment rod, the drive rod and the abutment rod can be reset under the action of the reset member; then when the slurry in the auxiliary pipeline flows out, the sealing plate is closed, and the limit block is re-inserted into the limit groove on the sealing plate. When the gate plate in the gate valve is opened, the push block contacts the abutment rod, and the push block rotates, thereby failing to push the drive rod and the limit block to move. The limit block is always inserted in the sealing plate, and the sealing plate always remains in a closed state, thereby preventing the slurry from flowing out of the through hole when the gate valve is opened.

[0021] Preferably, a second spring is provided on the side wall of the auxiliary pipeline, and the two ends of the second spring are respectively fixedly arranged on the limit block and the auxiliary pipeline; the limit block is provided with an inclined surface, and the limit block is slidably matched with the sealing plate through the inclined surface.

[0022] By adopting the above technical solution, when the sealing plate needs to be closed, the limit block can be pushed to move through the inclined surface on the limit block during the rotation of the sealing plate, and the spring 2 is stretched. When the sealing plate rotates to the position corresponding to the limit block and the limit groove, the elastic force of the spring 2 can pull the limit block to be inserted into the limit groove on the sealing plate, thereby reducing the difficulty of limiting the sealing plate and reducing the possibility of the sealing plate rotating open.

[0023] Preferably, the reset member is a spring three, and two ends of the spring three are respectively fixedly arranged on the side wall of the secondary pipe and the driving rod.

[0024] By adopting the above technical solution, when the driving rod moves in the direction away from the auxiliary pipeline, spring three is stretched. Then, when the push block moves away from the abutment rod, the elastic force of spring three can pull the driving rod to the initial position, so as to drive the limit block to move again.

[0025] Preferably, a reset plate is vertically slidable in the dredging tube, a spring four is provided on the reset plate, two ends of the spring four are respectively fixed on the reset plate and the inner wall of the dredging tube, a connecting rod is also provided in the dredging tube, two ends of the connecting rod are respectively hinged to the sealing plate and the reset plate.

[0026] By adopting the above technical solution, when the sealing plate is rotated and opened, the weight of the slurry can press the sealing plate to rotate, and the sealing plate can drive the connecting rod to rotate, and the connecting rod can push the reset plate to move downward, and the spring four is compressed. When the slurry gradually flows out, the weight of the slurry on the sealing plate gradually decreases, and the elastic force of the spring four can gradually push the sealing plate to close, thereby reducing the difficulty of closing the sealing plate and reducing the work intensity of the staff.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] When the filtration system or equipment on the main pipeline needs to be repaired, the main valve on the main pipeline can be closed first, and then the valve on the secondary pipeline can be opened. At this time, the slurry can flow through the secondary pipeline. The multi-stage filtration mechanism set in the secondary pipeline can temporarily filter the slurry. The multi-stage filtration can gradually remove particles of different sizes, and each stage is targeted at a specific particle size, thereby improving the overall filtration efficiency; at the same time, pre-filtration can intercept larger particles, reduce wear on subsequent filter media, and extend its service life; the whole process is convenient for staff to repair and maintain equipment without affecting the operation of the production line, thereby improving production continuity and production efficiency, and thus improving the economic benefits of the enterprise;

[0029] When the slurry flows normally in the secondary pipeline, the staff can turn on the motor, and the motor can drive the rotating plate to rotate, and the rotating plate can drive the universal joint on it to rotate. At this time, the end of the connecting rod close to the rotating plate rotates with the rotating plate. Due to the continuous change of the position of the universal joint on the rotating plate, the distance between the universal joint on the rotating plate and the universal joint on the slider is also constantly changing. Therefore, the connecting rod can rotate with the rotating plate and continuously drive the slider and the push plate to move back and forth. The push plate can push the filter plate to move, and the spring 1 is constantly squeezed and stretched. At this time, the filter plate can continuously vibrate under the push of the push plate and the elastic force of the spring 1, thereby helping the filter plate to separate solid particles and liquids faster and improve the overall filtration speed; at the same time, vibration can prevent excessive solid particles from accumulating on the surface of the filter medium and reduce the risk of blockage; in addition, since it can reduce material blockage and the frequency of filter medium replacement, it reduces maintenance costs;

[0030] When the motor drives its rotating shaft to rotate, it can drive roller one to rotate. At this time, belt one can be transmitted through two rollers, so as to drive another roller one to rotate. The other roller one can drive the telescopic rod to rotate. The telescopic rod can be continuously stretched and contracted following the reciprocating movement of the filter screen, so that the scraper can always fit the surface of the filter plate. The driving member can drive the scraper to rotate while the telescopic rod rotates. The rotation of the scraper can remove solid particles on the surface of the filter plate and prevent the filter plate from being blocked due to the accumulation of solid particles, thereby improving the filtration efficiency. At the same time, it can also reduce the wear of the filter plate on the solid particles and extend its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following is combined with Figure 1-8 This application is described in further detail.

[0042] The present application embodiment discloses a temporary filtration device for gold mines, such as Figure 1 and Figure 2 As shown, it includes a main pipeline 1, which is connected to a secondary pipeline 2, and a valve is arranged on the secondary pipeline 2. A multi-stage filtering mechanism 4 for filtering the slurry is arranged in the secondary pipeline 2. The multi-stage filtering mechanism 4 includes a plurality of filter plates 41, and the filter holes on the plurality of filter plates 41 have different aperture sizes. The plurality of filter plates 41 are sequentially installed in the secondary pipeline 2 along the length direction of the secondary pipeline 2 according to the different aperture sizes of the filter holes, and the aperture sizes on the plurality of filter plates 41 decrease sequentially from the upstream to the downstream direction of the secondary pipeline 2.

[0043] like Figure 1 and Figure 2As shown, when the filtering system or equipment on the main pipeline 1 needs to be repaired, the main valve on the main pipeline 1 can be closed first, and then the valve on the secondary pipeline 2 can be opened. At this time, the slurry can flow in the secondary pipeline 2, and the multi-stage filtering mechanism 4 arranged in the secondary pipeline 2 can temporarily filter the slurry. The multi-stage filtration can gradually remove particles of different sizes, and each stage is targeted at a specific particle size, thereby improving the overall filtration efficiency; at the same time, pre-filtration can intercept larger particles, reduce wear on subsequent filter media, and extend its service life; the whole process is convenient for staff to carry out equipment inspection and maintenance without affecting the operation of the production line, thereby improving production continuity and production efficiency, and then improving the economic benefits of the enterprise.

[0044] like Figure 2 and Figure 3 As shown, the upper and lower ends of the filter plate 41 are respectively inserted into the upper and lower inner walls of the auxiliary pipe 2, and slide horizontally on the inner wall of the auxiliary pipe 2. The upper and lower ends of the filter plate 41 are fixedly provided with sealing plates 5 on the opposite sides, and the sealing plates 5 slide horizontally on the inner wall of the auxiliary pipe 2. The multi-stage filtering mechanism 4 includes multiple groups of vibration components 42, and the multiple groups of vibration components 42 are correspondingly arranged with multiple filter plates 41.

[0045] like Figure 2 and Figure 3 As shown, the vibration assembly 42 includes a motor 421, a push plate 422 and a connecting rod 423. A bracket 424 is fixedly provided on the outer side wall of the top of the auxiliary pipe 2, and the motor 421 is installed on the bracket 424; the push plate 422 slides horizontally on the auxiliary pipe 2 along the length direction of the auxiliary pipe 2, and a connecting block 425 is fixedly connected to the top of the filter plate 41. The connecting block 425 slides horizontally on the side wall of the auxiliary pipe 2 and extends to the outer side of the top of the auxiliary pipe 2. The push plate 422 abuts against the connecting block 425; A rotating plate 426 is fixedly arranged on the rotating shaft of the machine 421, a sliding block 427 is arranged on the pushing plate 422, universal joints 428 are installed on the rotating plate 426 and the sliding block 427, the universal joint 428 on the rotating plate 426 is installed at an eccentric position on the rotating plate 426, and the two ends of the connecting rod 423 are respectively fixedly connected to the ball heads on the two universal joints 428; a spring 429 is arranged in the auxiliary pipe 2, and the two ends of the spring 429 are respectively fixedly arranged on the inner wall of the filter plate 41 and the auxiliary pipe 2.

[0046] like Figure 2 and Figure 3As shown, when the slurry flows normally in the auxiliary pipe 2, the staff can turn on the motor 421, the motor 421 can drive the rotating plate 426 to rotate, and the rotating plate 426 can drive the universal joint 428 thereon to rotate. At this time, the end of the connecting rod 423 close to the rotating plate 426 rotates with the rotating plate 426. Due to the continuous change of the position of the universal joint 428 on the rotating plate 426, the distance between the universal joint 428 on the rotating plate 426 and the universal joint 428 on the slider 427 is also constantly changing. Therefore, the connecting rod 423 can rotate with the rotating plate 426 and continuously drive the slider 427. The push plate 422 moves back and forth, and the push plate 422 can push the filter plate 41 to move. The spring 429 is constantly squeezed and stretched. At this time, the filter plate 41 can be pushed by the push plate 422 and the elastic force of the spring 429 to continuously vibrate, thereby helping the filter plate 41 to separate solid particles and liquids faster and improve the overall filtration speed; at the same time, vibration can prevent excessive accumulation of solid particles on the surface of the filter medium and reduce the risk of clogging; in addition, since the clogging of the material and the replacement frequency of the filter medium can be reduced, the maintenance cost is reduced.

The driving member can make the telescopic rod 442 drive the scraper 43 to rotate while rotating. The rotation of the scraper 43 can remove solid particles on the surface of the filter plate 41 and prevent the filter plate 41 from being blocked due to the accumulation of solid particles, thereby improving the filtration efficiency. At the same time, it can also reduce the wear of the filter plate 41 by solid particles and extend its service life.

The hose 7 usually has a certain expansion capacity. When the liquid in the pipeline increases, the hose 7 can expand to adapt to the pressure change, thereby reducing the pressure impact on other parts of the pipeline system; the hose 7 set at the same time can reduce noise and structural stress; at the same time, the hose 7 can adapt to the expansion or contraction of the pipeline caused by the flow of liquid, and maintain the integrity of the pipeline system; the hose 7 can distribute the pressure more evenly and reduce the pressure concentration in local areas of the pipeline system.

[0054] like Figure 2 , Figure 3 and Figure 5As shown, when the filter plate 41 is blocked, the hose 7 expands, and at this time the hose 7 can push the drive plate 8 to move, and the drive plate 8 can push the threaded rod 16 to move vertically, and the threaded rod 16 drives one of the rollers 2 12 to rotate, and the roller 2 12 drives the other roller 2 12 to rotate through the belt 20, and the other roller 2 12 drives the lead screw 13 to rotate, and the lead screw 13 drives the slider 427 to move, so that the distance between the universal joint 428 on the slider 427 and the universal joint 428 on the rotating plate 426 can be changed, so that the distance between the universal joint 428 on the slider 427 and the universal joint 428 on the rotating plate 426 is increased, and then the movement amplitude of the push plate 422 can be increased, and the vibration amplitude of the filter plate 41 is increased, and the possibility of blockage of the filter plate 41 is further reduced, and the filtering efficiency of the filter plate 41 is improved, which helps to relieve the local pressure of the auxiliary pipeline 2.

[0055] like Figure 1 , Figure 2 and Figure 5 As shown, the bottom of the auxiliary pipeline 2 before each filter plate 41 is connected to the dredging pipe 22, and the side wall of the bottom of the auxiliary pipeline 2 is provided with a through hole 23, which is connected to the dredging pipe 22, and the outlet of the dredging pipe 22 is connected to the collecting box 24; a sealing plate 25 is provided at the through hole 23, one end of the sealing plate 25 is hinged to the side wall of the auxiliary pipeline 2, and the opposite side walls of the auxiliary pipeline 2 are provided with horizontal sliding limit blocks 26, and the opposite side walls of the sealing plate 25 are provided with limit grooves 27 for the limit blocks 26 to be inserted; the valve is a gate valve 270, and the control component on the auxiliary pipeline 2 is used to control the movement of the gate plate in the gate valve 270; the auxiliary pipeline 2 is provided with a second driving component 28 for driving the limit block 26 to move.

[0056] like Figure 5 As shown, the control component includes a controller and a pressure sensor. The input end of the controller is electrically connected to the output end of the pressure sensor to receive a pressure sensing signal; the control end of the controller is electrically connected to the control end of the gate valve 270 to control the switch of the electric valve in response to the pressure sensing signal.

[0057] like Figure 1 , Figure 2 and Figure 5As shown, when the slurry in the pipeline flows normally, the sealing plate 25 is in a closed state, and the limit block 26 is inserted into the limit groove 27 on the sealing plate 25. When the pressure in the auxiliary pipeline 2 continues to increase, the pressure sensor can detect the pressure in the auxiliary pipeline 2. After receiving the pressure signal, the controller can control the gate plate in the gate valve 270 to close. During the closing process of the gate plate in the gate valve 270, the second drive component 28 can be triggered. The second drive component 28 can drive the limit block 26 to move to a position away from the sealing plate 25, and then the sealing plate 25 can be rotated to open, and the slurry in the auxiliary pipeline 2 can flow out from the dredging pipe 22 to the collecting box 24, thereby reducing the accumulated solid particles in the pipeline, reducing the possibility of the filter plate 41 being blocked, and thus reducing the pressure in the pipeline.

[0058] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the second driving assembly 28 includes a driving rod 281 and an abutting rod 282. The driving rod 281 slides horizontally on the side wall of the auxiliary pipeline 2. A plurality of guide rods 283 are fixedly arranged on the side wall of the auxiliary pipeline 2. The guide rods 283 are arranged horizontally. The guide rods 283 are penetrated and slide on the driving rod 281. One end of the limit block 26 is fixedly arranged on the driving rod 281, and one end of the abutting rod 282 is fixedly arranged on the driving rod 281. One end of the abutting rod 282 slides horizontally in the side wall of the auxiliary pipeline 2, and the top of the abutting rod 282 close to the gate valve 270 is provided with an inclined surface. The side wall of the gate plate in the gate valve 270 is hinged with a push block 284 through a torsion spring. A stop block 285 is arranged above the push block 284. The stop block 285 is fixedly arranged on the gate plate in the gate valve 270, and the abutting rod 282 slides with the push block 284 through the inclined surface.

[0059] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the gate plate in the gate valve 270 can drive the push block 284 to move during the closing process. When the gate plate in the gate valve 270 is gradually closed, the push block 284 can contact the abutment rod 282 and push the abutment rod 282 to move through the inclined surface on the abutment rod 282. At this time, the push block 284 abuts against the stopper 285, and the push block 284 does not rotate. The abutment rod 282 can drive the drive rod 281 to move away from the auxiliary pipeline 2, and the drive rod 281 drives the limit block 26 to move away from the sealing plate 25, thereby reducing the difficulty of moving the limit block 26; then the gate plate in the gate valve 270 continues to move, and when the push block 284 When it moves to a position away from the abutment rod 282, the driving rod 281 and the abutment rod 282 can be reset under the action of the reset member; thereafter, when the slurry in the auxiliary pipeline 2 flows out, the sealing plate 25 is closed, and the limit block 26 is re-inserted into the limit groove 27 on the sealing plate 25. When the gate plate in the gate valve 270 is opened, the push block 284 contacts the abutment rod 282, and the push block 284 rotates, thereby failing to push the driving rod 281 and the limit block 26 to move. The limit block 26 is always inserted in the sealing plate 25, and the sealing plate 25 always remains in a closed state, thereby preventing the slurry from flowing out of the through hole 23 when the gate valve 270 is opened.

[0060] like Figure 2 , Figure 5 and Figure 8 As shown, a spring 29 is provided on the side wall of the auxiliary pipe 2. The spring 29 is horizontally arranged, and the two ends of the spring 29 are respectively fixed to the limit block 26 and the auxiliary pipe 2; the limit block 26 is provided with an inclined surface at the bottom near one end of the sealing plate 25, and the limit block 26 is slidably matched with the sealing plate 25 through the inclined surface.

[0061] like Figure 5 and Figure 6 As shown, the second driving assembly 28 also has a reset member for resetting the driving rod 281, and the reset member is a spring three 286, and both ends of the spring three 286 are respectively fixedly arranged on the side wall of the auxiliary pipeline 2 and the driving rod 281.

[0062] like Figure 5 , Figure 6 and Figure 8 As shown, when the driving rod 281 moves away from the auxiliary pipeline 2, the spring three 286 is stretched. Then, when the push block 284 moves away from the abutment rod 282, the elastic force of the spring three 286 can pull the driving rod 281 to move to the initial position, so as to drive the limit block 26 to move again.

[0063] like Figure 2 , Figure 5 and Figure 8As shown, when the sealing plate 25 needs to be closed, the limiting block 26 can be pushed to move by the inclined surface on the limiting block 26 during the rotation of the sealing plate 25, and the spring 29 is stretched. When the sealing plate 25 rotates to the position corresponding to the limiting block 26 and the limiting groove 27, the elastic force of the spring 29 can pull the limiting block 26 to be inserted into the limiting groove 27 on the sealing plate 25, thereby reducing the difficulty of limiting the sealing plate 25 and reducing the possibility of the sealing plate 25 rotating open.

[0064] like Figure 1 and Figure 5 As shown, a reset plate 30 is provided in the dredging tube 22, and guide rods 5 31 are vertically fixedly provided on the inner wall of the dredging tube 22 on opposite sides of the reset plate 30, and the reset plate 30 slides on the guide rods 5 31. Springs 4 32 are provided on opposite sides of the reset plate 30, and the springs 4 32 are vertically provided. The two ends of the springs 4 32 are respectively fixedly provided on the reset plate 30 and the inner wall of the dredging tube 22. A connecting rod 33 is also provided in the dredging tube 22, and the two ends of the connecting rod 33 are respectively hinged to the sealing plate 25 and the reset plate 30.

[0065] like Figure 1 and Figure 5 As shown, when the sealing plate 25 is rotated to open, the weight of the slurry can press the sealing plate 25 to rotate, and the sealing plate 25 can drive the connecting rod 33 to rotate, and the connecting rod 33 can push the reset plate 30 to move downward, and the spring four 32 is compressed. When the slurry gradually flows out, the weight of the slurry on the sealing plate 25 gradually decreases, and the elastic force of the spring four 32 can gradually push the sealing plate 25 to close, thereby reducing the difficulty of closing the sealing plate 25 and reducing the work intensity of the staff.

[0066] The implementation principle of the embodiment of the present application is: when the filtering system or equipment on the main pipeline 1 needs to be repaired, the main valve on the main pipeline 1 can be closed first, and then the valve on the secondary pipeline 2 can be opened. At this time, the slurry can flow in the secondary pipeline 2, and the multi-stage filtering mechanism 4 arranged in the secondary pipeline 2 can temporarily filter the slurry. The multi-stage filtration can gradually remove particles of different sizes, and each stage is targeted at a specific particle size, thereby improving the overall filtration efficiency; at the same time, pre-filtration can intercept larger particles, reduce the wear on subsequent filter media, and extend its service life; the whole process is convenient for the staff to carry out equipment inspection and maintenance without affecting the operation of the production line, thereby improving production continuity and production efficiency, and then improving the economic benefits of the enterprise.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
