Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically relating to a wastewater treatment device and method for water jet looms. Background Technology

[0002] Water jet looms are shuttleless looms that use jet water to pull the weft yarn through the shed. High-pressure water flow drives the weft yarn to interweave with the warp yarn at high speed. They are characterized by high speed, high efficiency, low noise, and suitability for the production of hydrophobic fabrics. They are commonly used equipment in the manufacture of chemical fiber fabrics.

[0003] Patent application CN217148809U discloses a wastewater treatment device for water-jet looms. This device can not only agitate the wastewater but also filter it with fibrous materials, thereby improving the wastewater treatment efficiency. Although the device can filter fibrous materials, in actual use, after the filter plate assembly filters wastewater for a long time, a large amount of fibrous materials will adhere to the filter plate assembly, affecting the filtration effect and the passage of wastewater. To ensure the normal use of the filter plate assembly, it is necessary to clean it. However, the filter plate assembly is located inside the wastewater treatment inner cylinder. Cleaning the filter plate assembly requires removing the wastewater treatment inner cylinder, and after cleaning the filter plate assembly, the wastewater treatment inner cylinder needs to be reinstalled. Moreover, cleaning the filter plate assembly requires stopping the wastewater treatment operation, which is cumbersome and complicated, and will affect the progress of the wastewater treatment operation, reducing work efficiency.

[0004] Patent application CN214990692U discloses a dynamic filtration and adsorption device for treating wastewater from water-jet loom production. By setting up a filtration component and an adsorption component, with three layers of filter screens inside the filtration component, the filtration effect is better than a single filter screen. Although the device can treat wastewater, after a period of use, in order to maintain high efficiency, the filtration and adsorption components need to be removed and the filter plates cleaned. This operation is cumbersome and complex, and the wastewater treatment process cannot continue while the filter plates are being cleaned, affecting the progress of wastewater treatment and reducing work efficiency. Summary of the Invention

The second connecting rod and the positioning plate are provided with symmetrically arranged slots at the positions corresponding to the insertion rods. The upper end of the insertion rod is connected to a pull ring, and a first spring is connected between the pull ring and the second connecting rod.

[0008] Preferably, the motor drives the fourth sprocket, which rotates synchronously with one of the first sprockets via the third sprocket and the second chain. The middle of the side of the first sprocket away from the synchronous shaft passes through the outer frame and is connected to the third sprocket. A motor is installed on the upper part of the outer frame corresponding to the position of the third sprocket. The output end of the motor is connected to the fourth sprocket. The second chain is engaged on the outer sides of both the third sprocket and the fourth sprocket.

[0009] Preferably, the impurities in the collection box are conveyed and discharged through the first rotating rod and the auger blades. The collection box is connected to the upper part of the outer frame away from the water inlet pipe. The first rotating rod is rotatably connected inside the collection box, and the auger blades are connected to the outside of the first rotating rod.

[0010] Preferably, the first rotating rod and the third rotating rod rotate synchronously through the fifth sprocket, the sixth sprocket and the third chain. The end of the first rotating rod near the motor passes through the collection box and is connected to the fifth sprocket. The sixth sprocket is connected to the middle of the side of the third sprocket away from the outer frame. The third chain meshes with the outer sides of the fifth sprocket and the sixth sprocket.

[0011] Preferably, the first sprocket and the second rotating rod rotate synchronously through the first pulley, the second pulley and the belt. The second rotating rod is set above the outer frame at the position corresponding to the collecting plate. The end of the second rotating rod away from the third chain is connected to the first pulley. The middle part of the side of the first sprocket away from the third chain that is away from the synchronous shaft passes through the outer frame and is connected to the second pulley. A belt is slidably connected between the first pulley and the second pulley.

[0012] Preferably, the second rotating rod and the reciprocating lead screw are rotated synchronously by the first bevel gear and the second bevel gear. The first bevel gear is connected to the middle of the second rotating rod, and the second bevel gear is engaged on the outer side of the first bevel gear away from the outer frame. The reciprocating lead screw is connected to the middle of the side of the second bevel gear away from the first bevel gear.

[0013] Preferably, the moving rod, the first push plate and the second push plate are moved back and forth by a reciprocating screw. The moving rod is threaded to the outside of the reciprocating screw, the lower end of the moving rod is connected to the first push plate, the second push plate is slidably connected inside the first push plate, and a plurality of evenly arranged second springs are connected between the first push plate and the second push plate.

[0014] Preferably, the second push plate is brought into the first push plate by means of the rotating block and the extrusion plate. A symmetrically arranged receiving groove is provided at the lower part of the processing pool near the feed pipe. A rotating block is rotatably connected to the receiving groove near the feed pipe. The rotating block is rotatably connected to the processing pool by means of a sleeve rod. A torsion spring is connected between the processing pool and the rotating block. An extrusion plate is connected to the side of the rotating block away from the receiving groove.

[0015] The present invention also provides a wastewater treatment method for water jet looms, comprising the following steps: S1: Check if the cutting blade needs to be replaced.

[0016] S2: Wastewater is sent into the treatment tank through the inlet pipe. After the wastewater in the treatment tank reaches a certain height, the outlet pipe is opened. Through the first valve and the second valve, the inflow and outflow are made consistent, so that the wastewater in the treatment tank flows.

[0017] S3: Start the motor to make the fourth sprocket and the third sprocket rotate synchronously. The third sprocket drives the first sprocket to rotate, which in turn drives the first chain to rotate. The first chain drives the first connecting rod and the toothed rake to move in a cycle. During the movement, the toothed rake will enter the collection trough and carry out the impurities in the collection trough. The impurities that are carried out will be above the V-shaped toothed rake, and the toothed rake will transport the impurities.

[0018] S4: During the rotation of the first chain, the second connecting rod and the cutting blade will move in a cycle. During the movement, the cutting blade will enter the collection trough and cut the weft yarn wrapped on the collection plate.

[0019] S5: The third sprocket drives the sixth sprocket to rotate. The sixth sprocket rotates synchronously with the fifth sprocket. The fifth sprocket drives the first rotating rod and the auger blades to rotate, conveying the impurities in the collection box to the discharge pipe for discharge and collection.

[0020] S6: The first sprocket drives the second pulley to rotate. The first pulley and the second pulley rotate synchronously. The first pulley drives the second rotating rod to rotate. The second rotating rod cooperates with the first bevel gear and the second bevel gear to make the reciprocating screw and the second rotating rod rotate synchronously, driving the moving plate, the first push plate and the second push plate to move back and forth, pushing the impurities in the treatment pool toward the collection plate.

[0021] S7: When the second push plate moves away from the collection plate, it contacts the extrusion plate, causing the second push plate to enter the first push plate. After the second push plate moves past the extrusion plate, it moves out of the first push plate, so that one side of the first push plate is close to the inner wall of the treatment tank and the lower surface is close to the bottom of the treatment tank. When the second push plate moves towards the collection plate, it pushes the impurities that have moved away from the collection plate back towards the collection plate.

[0022] S8: When the second push plate moves closer to the collecting plate, it contacts the extrusion plate, causing the second push plate to push the extrusion plate. The rotating block rotates around the sleeve rod as the center and causes the extrusion plate to enter the collection slot. After the second push plate moves past the collection slot, the extrusion plate will reset to prepare for the next blocking of the second push plate.

[0023] The beneficial effects of this invention are: 1) Wastewater is fed into the treatment tank through the inlet pipe. Once the wastewater reaches a certain height, the outlet pipe is opened, and the inflow and outflow of the inlet pipe are matched by the first and second valves, thus ensuring the wastewater flows freely. As the wastewater flows past the collection plate, impurities are blocked and concentrated in the collection trough, achieving filtration. The filtered wastewater is then discharged through the outlet pipe, achieving the purpose of wastewater filtration. 2) By starting the motor, the first chain rotates, driving the first connecting rod and the rake to move in a cycle. The rake enters the collection trough during its movement, carrying out impurities. These impurities are then transported above the V-shaped rake, and with the help of the anti-fall plate, they are guided into the collection box for collection, preventing them from falling into the treatment tank during transport. This allows for the collection and treatment of impurities in the wastewater during the treatment process, making operation simple and convenient, without affecting the wastewater treatment process, and improving work efficiency.

[0024] 2) The wastewater contains weft yarn. During the process of the collection plate filtering the wastewater, the weft yarn may get tangled on the collection plate, which will affect the normal operation of the rake. When the first chain rotates, it will drive the second connecting rod and the cutting blade to move in a cycle. During the movement, the cutting blade will enter the collection trough, thereby cutting off the weft yarn tangled on the collection plate and avoiding affecting the operation of the rake.

[0025] 3) The rotation of the first rotating rod drives the auger blades to rotate. During the rotation of the auger blades, the impurities in the collection box are transported. When the impurities are transported to the position of the discharge pipe, they can be discharged and collected to prevent the collection box from accumulating too many impurities and causing them to overflow.

[0026] 4) The reciprocating screw rotates, driving the moving plate to move back and forth. During the reciprocating movement of the moving plate, the first push plate and the second push plate move back and forth, thereby pushing the impurities in the treatment tank toward the collection plate and preventing the impurities from accumulating at the bottom of the treatment tank. When the second push plate moves away from the collection plate, it contacts the extrusion plate, causing the second push plate to enter the first push plate. After the second push plate moves past the extrusion plate, it moves out of the first push plate, so that one side of the first push plate is close to the inner wall of the treatment tank and the lower surface is close to the bottom of the treatment tank. When the second push plate moves away from the collection plate, it will push some impurities away from the collection plate. With the cooperation of the extrusion plate, when the second push plate moves toward the collection plate, it can push these impurities back toward the collection plate for collection.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 - Figure 3 As shown, a wastewater treatment device for a water jet loom includes a treatment tank 1, which is used to collect wastewater.

[0032] A water inlet pipe 11 is connected to the upper part of one end of the treatment tank 1. A first valve 12 is connected to the middle of the water inlet pipe 11. The water inlet pipe 11 is used to introduce wastewater into the treatment tank 1, and the first valve 12 is used to control the opening and closing of the water inlet pipe 11.

[0033] The treatment tank 1 is connected to an outlet pipe 13 at the lower end away from the inlet pipe 11. A second valve 14 is connected to the middle of the outlet pipe 13. The outlet pipe 13 is used to discharge the treated wastewater, and the second valve 14 is used to control the opening and closing of the outlet pipe 13.

[0034] A collection plate 15 is installed inside the treatment tank 1 at a position away from the inlet pipe 11. The collection plate 15 is used to collect impurities in the wastewater.

[0035] The upper end of the collecting plate 15 is arc-shaped. This design ensures that the upper end of the collecting plate 15 will not obstruct the rake 241 when it is cleaning impurities in the collection trough 242.

[0036] An outer frame 2 is installed inside the treatment tank 1 at a position away from the water inlet pipe 11, and the outer frame 2 corresponds to the collection plate 15. The outer frame 2 is used to support and fix the first sprocket 22 and the second sprocket 221.

[0037] The outer frame 2 is connected to a symmetrically arranged first support plate 21 at a position above the treatment pool 1. The outer side of the treatment pool 1 is connected to a symmetrically arranged second support plate 211 at a position above the first support plate 21. Multiple evenly arranged bolts 212 are threaded between the first support plate 21 and the second support plate 211. Through the cooperation of the first support plate 21, the second support plate 211 and the bolts 212, the outer frame 2 can be fixed on the treatment pool 1.

[0038] A first sprocket 22 is rotatably connected to the upper part of the outer frame 2 near the water outlet pipe 13. A second sprocket 221 is rotatably connected to the lower part of the outer frame 2. Synchronous shafts 222 are connected between the first sprockets 22 and between the second sprockets 221. A first chain 223 is meshed on the outer side of the first sprockets 22 and the second sprockets 221. Through the cooperation of the synchronous shafts 222 and the first chain 223, the first sprockets 22 and the second sprockets 221 can rotate synchronously.

[0039] Two arc-shaped guide plates 224 are connected to the upper part of the outer frame 2, corresponding to the position of the first chain 223. The first chain 223 is in contact with the upper surface of the guide plate 224. The guide plate 224 is used to support, guide and tension the first chain 223. The first chain 223 is tensioned into an L shape under the action of the guide plate 224 to ensure that impurities are sent into the collection box 4.

[0040] Multiple evenly arranged first connecting rods 24 are connected between the first chain 223. Evenly arranged V-shaped rakes 241 are connected to the outside of the first connecting rods 24. The rakes 241 are used to clean and collect impurities in the collection trough 242. When transporting impurities, the rakes 241 are set in a V shape to prevent impurities from falling out of the rakes 241.

[0041] The collecting plate 15 has multiple evenly arranged collecting troughs 242 at the position corresponding to the toothed rake 241. The toothed rake 241 moves between the toothed rakes 241 and the collecting troughs 242 are used to collect impurities in the wastewater.

[0042] An L-shaped anti-fall plate 243 is connected inside the outer frame 2 at the position corresponding to the toothed rake 241, and the anti-fall plate 243 is located inside the first chain 223. The anti-fall plate 243 is used to block impurities and prevent impurities from falling from the toothed rake 241.

[0043] In practical use, wastewater is sent into treatment tank 1 through inlet pipe 11. After the wastewater in treatment tank 1 reaches a certain height, outlet pipe 13 is opened, and the inflow rate of inlet pipe 11 and the outflow rate of outlet pipe 13 are made consistent through first valve 12 and second valve 14, thereby achieving the purpose of wastewater flow in treatment tank 1. After the wastewater flows through collection plate 15, impurities in the wastewater are blocked and concentrated in collection trough 242, thus filtering the wastewater. The filtered wastewater is discharged through outlet pipe 13, achieving the purpose of wastewater filtration. The rotation of one of the first sprockets 22, under the action of synchronous shaft 222, enables the two first sprockets 22 to rotate synchronously. The first sprocket 22 cooperates with the second sprocket. 221, causing the two first chains 223 to rotate synchronously. During the rotation of the first chains 223, the first connecting rod 24 and the toothed rake 241 move in a cycle. During the movement, the toothed rake 241 enters the collection trough 242 and carries out the impurities in the collection trough 242. The impurities carried out will be above the V-shaped toothed rake 241. The toothed rake 241 transports the impurities. With the cooperation of the anti-fall plate 243, the impurities can be guided into the collection box 4 for collection, preventing the impurities from falling into the treatment pool 1 during the transportation process. During the wastewater treatment process, the impurities in the wastewater can be collected and treated. The operation is simple and convenient, does not affect the progress of wastewater treatment, and improves work efficiency.

[0044] Please see Figure 1 , Figure 3 , Figure 4 as well as Figure 6 As shown, a second connecting rod 3 is connected between the first chain 223, and the second connecting rod 3 is used to support the positioning plate 32 and the cutting blade 33.

[0045] The positioning plate 32 is fixed in the positioning groove 31 of the second connecting rod 3 by means of the insertion rod 35 and the slot 34.

[0046] The second connecting rod 3 has a positioning groove 31 near the collecting plate 15. A positioning plate 32 is inserted into the positioning groove 31. A cutting blade 33 is connected to the side of the positioning plate 32 away from the second connecting rod 3. The positioning groove 31 is used to determine the installation position of the positioning plate 32. The positioning plate 32 is used to support the cutting blade 33. The cutting blade 33 is used to cut the weft yarn wrapped on the collecting plate 15.

[0047] The second connecting rod 3 is provided with symmetrically arranged insert rods 35 above it. The second connecting rod 3 and the positioning plate 32 are provided with symmetrically arranged slots 34 at the positions corresponding to the insert rods 35. The insert rods 35 are inserted into the slots 34. Through the cooperation between the insert rods 35 and the slots 34, the positioning plate 32 can be fixed in the positioning groove 31.

[0048] A pull ring 37 is connected to the upper end of the insertion rod 35. The pull ring 37 is used to pull the insertion rod 35 out of the slot 34.

[0049] A first spring 36 is connected between the pull ring 37 and the second connecting rod 3. The first spring 36 is used to reset the insert rod 35.

[0050] In practical use, the wastewater contains weft yarn. During the process of filtering the wastewater by the collection plate 15, the weft yarn may get tangled on the collection plate 15, which may affect the normal operation of the toothed rake 241. During the rotation of the first chain 223, the second connecting rod 3 and the cutting blade 33 will move in a cycle. During the movement, the cutting blade 33 will enter the collection trough 242, thereby cutting off the weft yarn tangled on the collection plate 15 and avoiding affecting the operation of the toothed rake 241. When the cutting blade 33 needs to be replaced after it is damaged, pull the two pull rings 37 upward to move the insertion rod 35 out of the slot 34, thereby causing the positioning plate 32 to lose its fixation. As the pull rings 37 are pulled upward, they will stretch the first spring 36. After the first spring 36 is stretched, it will store a restoring force. After the positioning plate 32 loses its fixation, it can be removed from the positioning groove 31, and a new positioning plate 32 and cutting blade 33 can be replaced. After inserting the new positioning plate 32 into the positioning groove 31, slowly release the pull rings 37. Under the action of the restoring force of the first spring 36, the insertion rod 35 will reset and insert into the slot 34, thus fixing the positioning plate 32. This makes the installation and removal of the positioning plate 32 more convenient and can improve work efficiency.

[0051] Please see Figure 1 , Figure 2 as well as Figure 4 As shown, one of the first sprockets 22 passes through the outer frame 2 in the middle of the side away from the synchronous shaft 222 and is connected to the third sprocket 23. A motor 231 is provided on the upper part of the outer frame 2 at the position corresponding to the third sprocket 23.

[0052] Motor 231 drives fourth sprocket 232, which in turn rotates synchronously with one of the first sprockets 22 via third sprocket 23 and second chain 233.

[0053] The output end of the motor 231 is connected to the fourth sprocket 232. The third sprocket 23 and the fourth sprocket 232 are both meshed with the second chain 233. The motor 231 is used to drive the third sprocket 23 to rotate. With the cooperation of the fourth sprocket 232 and the second chain 233, the third sprocket 23 and the fourth sprocket 232 can rotate synchronously, thereby enabling the synchronous shaft 222 to rotate.

[0054] A support base 234 is connected to the upper surface of the outer frame 2 at the position corresponding to the motor 231. The motor 231 is connected to the support base 234, and the support base 234 is used to support and fix the motor 231.

[0055] In practical use, by starting the motor 231, the motor 231 drives the fourth sprocket 232 to rotate. With the cooperation of the second chain 233, the fourth sprocket 232 rotates synchronously with the third sprocket 23. The rotation of the third sprocket 23 drives the first sprocket 22 to rotate, thereby driving the first chain 223 to rotate.

[0056] Please see Figure 1 - Figure 4 As shown, a collection box 4 is connected above the end of the outer frame 2 away from the water inlet pipe 11, and the collection box 4 is located below the first sprocket 22. The collection box 4 is used to collect impurities.

[0057] Impurities in the collection box 4 are conveyed and discharged through the first rotating rod 41 and the auger blades 42.

[0058] The first rotating rod 41 is rotatably connected inside the collection box 4, and the auger blade 42 is connected to the outside of the first rotating rod 41. By rotating the first rotating rod 41, the auger blade 42 can be driven to rotate, thus conveying impurities.

[0059] The bottom of the collection box 4, away from the motor 231, is connected to a discharge pipe 43, which is used to discharge impurities.

[0060] The first rotating rod 41 and the third sprocket 23 rotate synchronously through the fifth sprocket 44, the sixth sprocket 45 and the third chain 46.

[0061] The first rotating rod 41, near the motor 231, passes through the collection box 4 and is connected to the fifth sprocket 44. The third sprocket 23 is connected to the middle of the side away from the outer frame 2 by the sixth sprocket 45. The fifth sprocket 44 and the sixth sprocket 45 are meshed with the third chain 46 on their outer sides. Through the cooperation of the fifth sprocket 44, the sixth sprocket 45 and the third chain 46, the first rotating rod 41 and the third chain 46 can rotate synchronously.

[0062] In practical use, the rotation of the third sprocket 23 drives the rotation of the sixth sprocket 45. The sixth sprocket 45, in conjunction with the third chain 46, causes the sixth sprocket 45 to rotate synchronously with the fifth sprocket 44. The rotation of the fifth sprocket 44 drives the first rotating rod 41 to rotate, and the rotation of the first rotating rod 41 drives the auger blades 42 to rotate. During the rotation of the auger blades 42, the impurities in the collection box 4 are conveyed. When the impurities are conveyed to the position of the discharge pipe 43, they can be discharged and collected, preventing the collection box 4 from accumulating too many impurities and causing them to overflow.

[0063] Please see Figure 1 - Figure 5 , Figure 7 as well as Figure 8 As shown, a second rotating rod 5 is provided above the outer frame 2 at the position corresponding to the collection plate 15. The first sprocket 22 and the second rotating rod 5 rotate synchronously through the first pulley 51, the second pulley 52 and the belt 53.

[0064] The second rotating rod 5 is connected to the first pulley 51 at the end away from the third chain 46. The first sprocket 22, which is away from the third chain 46, passes through the outer frame 2 at the middle of the side away from the synchronous shaft 222 and is connected to the second pulley 52. ​​A belt 53 is slidably connected between the first pulley 51 and the second pulley 52. ​​Through the cooperation of the first pulley 51, the second pulley 52 and the belt 53, the second rotating rod 5 can rotate synchronously with the first sprocket 22.

[0065] The second rotating rod 5 and the reciprocating lead screw 56 rotate synchronously through the first bevel gear 54 and the second bevel gear 55.

[0066] The second rotating rod 5 is connected to the middle of the first bevel gear 54. The outer side of the first bevel gear 54, away from the outer frame 2, is engaged with the second bevel gear 55. The middle of the side of the second bevel gear 55 away from the first bevel gear 54 is connected to the reciprocating screw 56. Through the cooperation of the first bevel gear 54 and the second bevel gear 55, the reciprocating screw 56 can rotate synchronously with the second rotating rod 5. The reciprocating screw 56 is used to drive the moving rod 59 to move back and forth.

[0067] The reciprocating screw 56 causes the moving rod 59, the first push plate 591, and the second push plate 595 to move back and forth.

[0068] A first fixing plate 57 is connected to the upper surface of the outer frame 2 at the position corresponding to the second rotating rod 5 and the reciprocating screw 56. The second rotating rod 5 and the reciprocating screw 56 are rotatably connected to the first fixing plate 57. The first fixing plate 57 is used to support and fix the second rotating rod 5 and the reciprocating screw 56.

[0069] A second fixing plate 58 is connected to the end of the reciprocating screw 56 away from the first bevel gear 54 on the upper surface of the outer frame 2. The reciprocating screw 56 is rotatably connected to the second fixing plate 58, and the second fixing plate 58 is used to support and fix the reciprocating screw 56.

[0070] The reciprocating lead screw 56 is threaded to a moving rod 59 on its outer side, which is used to drive the first push plate 591 to move.

[0071] The lower end of the moving rod 59 is connected to a first push plate 591, which is located in the treatment pool 1. The first push plate 591 is used to push the impurities in the treatment pool 1 and at the same time drive the second push plate 595 to move.

[0072] A first limiting block 592 is connected to the upper surface of the first push plate 591. A limiting rod 593 is connected to the processing pool 1 at the position corresponding to the first limiting block 592. A second limiting block 594 is connected to the end of the limiting rod 593 near the collection plate 15 in the processing pool 1. The limiting rod 593 is connected to the second limiting block 594. The limiting rod 593 is used to limit the movement position of the first push plate 591 to prevent the first push plate 591 from deflecting when moving, which would prevent the first push plate 591 from moving. The second limiting block 594 is used to support and fix the limiting rod 593.

[0073] A second pusher plate 595 is slidably connected inside the first pusher plate 591. The second pusher plate 595 is used to push the impurities in the treatment pool 1.

[0074] A plurality of evenly arranged second springs 596 are connected between the first push plate 591 and the second push plate 595. The second springs 596 are used to reset the first push plate 591.

[0075] The second push plate 595 is brought into the first push plate 591 by the rotating block 61 and the pressing plate 64.

[0076] A symmetrically arranged storage trough 6 is provided inside the lower part of the processing tank 1 near the feed pipe. The storage trough 6 is used to store the extrusion plate 64.

[0077] A rotating block 61 is rotatably connected inside the storage tank 6 near the feed pipe, and the side of the rotating block 61 near the feed pipe is in close contact with the inner wall of the storage tank 6. The rotating block 61 is used to connect the extrusion plate 64 and drive the extrusion plate 64 to rotate.

[0078] The rotating block 61 is rotatably connected to the treatment tank 1 via a sleeve rod 62, which is used to fix the position of the rotating block 61.

[0079] A torsion spring 63 is connected between the processing pool 1 and the rotating block 61, and the torsion spring 63 is located inside the sleeve rod 62. The torsion spring 63 is used to reset the rotating block 61 and the pressing plate 64.

[0080] A pressing plate 64 is connected to the side of the rotating block 61 away from the storage slot 6. The pressing plate 64 is used to squeeze the second push plate 595 into the first push plate 591.

[0081] The second push plate 595 has a first inclined surface 65 on the side near the extrusion plate 64, and the extrusion plate 64 has a second inclined surface 66 on the side near the second push plate 595. The first inclined surface 65 and the second inclined surface 66 have the same inclination angle, and the first inclined surface 65 and the second inclined surface 66 are used in conjunction. Through the cooperation of the first inclined surface 65 and the second inclined surface 66, the second push plate 595 can enter the first push plate 591 more smoothly.

[0082] The processing pool 1 has a symmetrically arranged third inclined surface 67 at the position corresponding to the storage tank 6. The third inclined surface 67 is connected to the storage tank 6. The third inclined surface 67 is used to prevent impurities from being pushed into the storage tank 6, which would prevent the extrusion plate 64 from entering the storage tank 6.

[0083] In practical use, when the first sprocket 22 rotates, it drives the second pulley 52 to rotate. With the cooperation of the belt 53, the first pulley 51 and the second pulley 52 rotate synchronously. The rotation of the first pulley 51 drives the second rotating rod 5 to rotate. The rotation of the second rotating rod 5 cooperates with the first bevel gear 54 and the second bevel gear 55, so that the reciprocating screw 56 and the second rotating rod 5 rotate synchronously. The rotation of the reciprocating screw 56 drives the moving plate to move back and forth. During the reciprocating movement of the moving plate, it drives the first push plate 591 and the second push plate 595 to move back and forth, thereby pushing the impurities in the treatment tank 1 toward the collection plate 15 and preventing the impurities from accumulating in the lower part of the treatment tank 1. As the second push plate 595 moves away from the collecting plate 15, its second inclined surface 66 contacts the first inclined surface 65 of the extrusion plate 64. Because the side of the rotating block 61 closest to the feed pipe is pressed against the inner wall of the receiving groove 6, the second push plate 595 cannot push the extrusion plate 64 after contact. With the cooperation of the first inclined surface 65 and the second inclined surface 66, the second push plate 595 enters the first push plate 591. During its entry into the first push plate 591, the second push plate 595 compresses the second spring 596. After being compressed, the second spring 596 contracts and stores its restoring force. After the pusher plate 595 moves past the extrusion plate 64, the second pusher plate 595 loses its obstruction. Under the restoring force of the second spring 596, the second pusher plate 595 will move out of the first pusher plate 591. After the second pusher plate 595 moves out of the first pusher plate 591, one side of the first pusher plate 591 will approach the inner wall of the treatment tank 1, and the lower surface of the first pusher plate 591 will approach the bottom of the treatment tank 1. When the second pusher plate 595 moves away from the collection plate 15, it will push some impurities away from the collection plate 15. With the cooperation of the extrusion plate 64, when the second pusher plate 595 moves towards the collection plate 15, it can push these impurities closer to the collection plate 15 again for collection. When the second push plate 595 moves closer to the collecting plate 15, the plane of the second push plate 595 will contact the plane of the extrusion plate 64, causing the second push plate 595 to push the extrusion plate 64, causing the rotating block 61 to rotate around the sleeve rod 62 and put the extrusion plate 64 into the receiving groove 6. When the rotating block 61 rotates, it will tighten the torsion spring 63. After the torsion spring 63 tightens, it will store the restoring force. After the second push plate 595 moves past the receiving groove 6, the extrusion plate 64 will reset under the action of the restoring force of the torsion spring 63, preparing for the next blocking of the second push plate 595.

[0084] A method for treating wastewater from a water-jet loom includes the following steps: S1: Check if the cutting blade 33 needs to be replaced.

[0085] S2: Wastewater is sent into treatment tank 1 through inlet pipe 11. After the wastewater in treatment tank 1 reaches a certain height, outlet pipe 13 is opened. Through first valve 12 and second valve 14, the inflow and outflow are made consistent, so that the wastewater in treatment tank 1 flows.

[0086] S3: Start motor 231 to make the fourth sprocket 232 and the third sprocket 23 rotate synchronously. The third sprocket 23 drives the first sprocket 22 to rotate, which in turn drives the first chain 223 to rotate. The first chain 223 drives the first connecting rod 24 and the toothed rake 241 to move in a cycle. During the movement, the toothed rake 241 will enter the collection trough 242 and carry out the impurities in the collection trough 242. The impurities after being carried out will be above the V-shaped toothed rake 241, and the impurities will be transported by the toothed rake 241.

[0087] S4: During the rotation of the first chain 223, the second connecting rod 3 and the cutting blade 33 will move in a cycle. During the movement, the cutting blade 33 will enter the collection trough 242 and cut the weft yarn wrapped on the collection plate 15.

[0088] S5: The third sprocket 23 drives the sixth sprocket 45 to rotate. The sixth sprocket 45 and the fifth sprocket 44 rotate synchronously. The fifth sprocket 44 drives the first rotating rod 41 and the auger blade 42 to rotate, conveying the impurities in the collection box 4 to the position of the discharge pipe 43 for discharge and collection.

[0089] S6: The first sprocket 22 drives the second pulley 52 to rotate. The first pulley 51 and the second pulley 52 rotate synchronously. The first pulley 51 drives the second rotating rod 5 to rotate. The second rotating rod 5 cooperates with the first bevel gear 54 and the second bevel gear 55 to make the reciprocating screw 56 and the second rotating rod 5 rotate synchronously, driving the moving plate, the first push plate 591 and the second push plate 595 to reciprocate, pushing the impurities in the treatment pool 1 toward the collection plate 15.

[0090] S7: When the second push plate 595 moves away from the collection plate 15, the second push plate 595 contacts the extrusion plate 64, causing the second push plate 595 to enter the first push plate 591. After the second push plate 595 moves past the extrusion plate 64, the second push plate 595 moves out of the first push plate 591, so that one side of the first push plate 591 is close to the inner wall of the treatment tank 1 and the lower surface is close to the bottom of the treatment tank 1. When the second push plate 595 moves towards the collection plate 15, it pushes the impurities that have moved away from the collection plate 15 back towards the collection plate 15.

[0091] S8: When the second push plate 595 moves closer to the collecting plate 15, the second push plate 595 contacts the extrusion plate 64, causing the second push plate 595 to push the extrusion plate 64. The rotating block 61 rotates around the sleeve rod 62 as the center and causes the extrusion plate 64 to enter the storage groove 6. After the second push plate 595 moves past the storage groove 6, the extrusion plate 64 will reset, preparing for the next blocking of the second push plate 595.
