The water storage tank and the collection box are integrally formed with the central frame; it also includes: a diversion frame, which is arranged at the bottom position of the central frame, the diversion frame is communicated with the inside of the central frame, and an air extraction frame is arranged at the lower end of the diversion frame, and the air extraction frame is communicated with the inside of the diversion frame; an air extraction pump, which is arranged inside the central frame, and communication air pipes are arranged at both the air inlet end and the air outlet end of the air extraction pump, and both ends of the communication air pipe are respectively communicated with the air extraction frame and the collection box. However, this patent has the problem that the polyester filaments are likely to block the nozzles, which easily affects the water spraying and reduces the dust removal effect. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a dust removal device for a polyester filament texturing machine, which solves the problems mentioned in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A dust removal device for a polyester filament texturing machine includes a support frame, a lower layer guard plate is fixedly connected to the outer side of the lower half of the support frame, an upper layer guard plate is fixedly connected to the outer side of the upper half of the support frame, a top plate is fixedly connected to the top surface of the support frame, a dust removal mechanism is arranged inside the support frame, a collection mechanism is arranged behind the dust removal mechanism, a filtering mechanism is arranged behind the collection mechanism, and a water tank is arranged in the dust removal mechanism; The dust removal mechanism includes an air inlet groove, an air outlet groove is arranged above the air inlet groove, a branch air duct is fixedly connected to the right end of the rear side of the air inlet groove, a water spraying groove is fixedly connected to the front half of the inner wall of the water tank, two vertical plates are slidably connected inside the water spraying groove, a buoyancy block is fixedly connected to the bottom end of each vertical plate, an inclined block is fixedly connected to the front side of the left vertical plate, two guide rails are fixedly connected to the bottom surface of the water spraying groove, a flow baffle is slidably connected between the two guide rails, a thin column is fixedly connected to the left side surface of the flow baffle, a plurality of equally spaced inclined strips are fixedly connected to the bottom surface of the flow baffle, and a plurality of nozzles are fixedly connected to the bottom surface of the water spraying groove.

[0006] According to the above technical solution, a water injection port is arranged on the left side surface of the lower protective plate, a discharge chute is fixedly connected to the rear side surface of the upper protective plate, an installation groove is formed on the right side surface of the upper protective plate, a water tank is fixedly connected to the bottom surface of the water tank, and a fan is installed on the front side surface of the water tank.

[0007] According to the above technical solution, a swing handle is rotatably connected to the inner wall of the right side of the upper protective plate, three peristaltic wheels are rotatably connected to the outer edge of the swing handle, a peristaltic tube is arranged on the outer side surface of the peristaltic wheel, a connecting tube is fixedly connected to the rear end of the peristaltic tube, and a water outlet pipe is fixedly connected to the front end of the peristaltic tube.

[0008] According to the above technical solution, the water spraying groove is fixedly connected to the top end of the water outlet pipe, a strip groove is formed on the bottom surface of the flow baffle, and the strip groove corresponds to the position of the nozzle. The air inlet groove is fixedly connected to the fan. A spring piece is arranged at the rear side of the flow baffle, and two ends of the spring piece are respectively fixedly connected to the flow baffle and the bottom surface of the water spraying groove. When the fan is in a working state, the fan sucks the polyester filaments and dust mixed in the ambient air into the fan through the air inlet groove connected to the air inlet, and then discharges the air containing polyester filaments and dust from the air outlet of the fan into the air outlet groove. The air containing polyester filaments and dust in the air outlet groove is introduced into the water tank. At this time, the swing handle driven by an external motor makes the peristaltic wheel squeeze the air in the peristaltic tube. The air pressure in the peristaltic tube decreases, adsorbing the water in the connecting tube to fill the pressure. As the peristaltic wheel continues to rotate, the water in the peristaltic tube continuously drains into the water spraying groove through the water outlet pipe. The water entering the water spraying groove is sprayed out through the nozzle. The sprayed water makes the floating polyester filaments and dust settle and mix into the water, thereby playing a role in dust removal. When the water level in the water tank rises, the rising water surface will drive the buoyancy block to move up and push the vertical plate. At this time, the vertical plate will push the thin column, so that the thin column drives the connected flow baffle and inclined strips to slide along the guide rail together. The moved flow baffle will press the spring piece and rub against the end of the nozzle to block the nozzle. At this time, the nozzle no longer sprays water, resulting in a rapid drop in the water level of the water tank, and the buoyancy block also drops and resets together. At this time, the nozzle continues to spray water.

[0009] According to the above technical solution, the collection mechanism includes a filter screen cylinder, the filter screen cylinder is rotatably connected to the inner wall of the water tank, a claw is fixedly connected to the outer surface of the filter screen cylinder, a rotating shaft seat is rotatably connected to both the left and right sides of the filter screen cylinder, a rotary joint is threadedly connected to the left side of the filter screen cylinder, a discharge pipe is rotatably connected to the left side of the rotary joint, a water draining plate is fixedly connected to the rear inner wall of the water tank, a plurality of staggered groove plates are fixedly connected to the front side of the water draining plate, touch pressure rods are fixedly connected to both the left and right sides of the water draining plate, a crank is arranged between the filter screen cylinder and the rotating shaft seat, a push plate is fixedly connected between the two touch pressure rods, a partition board is arranged below the push plate, a filter plate is fixedly connected to the top inner wall of the branch air duct, a blanking baffle is rotatably connected to the inner wall of the discharge chute, and a guide bar is arranged directly below the blanking baffle.

[0010] According to the above technical solution, the filter screen cylinder and the swing handle are fixedly connected coaxially, the rotating shaft seat is fixedly connected to the support frame, the crank is fixedly connected to the filter screen cylinder, the blanking baffle is fixedly connected to the touch pressure rod, the partition board slides through to the inner side of the top of the branch air duct, the bottom surface of the filter plate is slidably connected to the top surface of the partition board, the top surface of the filter plate is slidably connected to the push plate, a elastic spring is arranged on the bottom surface of the rear end of the touch pressure rod, and both ends of the elastic spring are fixedly connected to the touch pressure rod and the water tank respectively, the guide bar is fixedly connected to the discharge chute. The polyester filaments floating in the water tank pass through the discharge pipe connected to the filter screen cylinder through the rotary joint to drain the water, driving the water flow to flow, so that the polyester filaments floating in the water tank flow towards the filter screen cylinder along with the water flow. As the filter screen cylinder rotates, the claws drive the polyester filaments floating on the water surface to be picked up. The polyester filaments collected outside the filter screen cylinder move relative to the staggered groove plates, and the polyester filaments are pushed onto the staggered groove plates by the claws. The polyester filaments on the staggered groove plates are adsorbed above the water draining plate through the branch air duct connected in the discharge chute. The polyester filaments pass above the water draining plate to drain the excess water and are adsorbed on the filter plate. While the filter screen cylinder rotates, it will drive the connected crank to swing and push the touch pressure rod to slide along the inner wall of the water tank and stretch the elastic spring. At this time, the movement of the touch pressure rod drives the partition board to block the branch air duct. At the same time, the touch pressure rod drives the push plate to push the polyester filaments on the filter plate into the discharge chute. During this process, the touch pressure rod will push the blanking baffle to turn over. When the elastic spring makes the touch pressure rod reset, the blanking baffle will also reset accordingly. The polyester filaments are separated from the dust mixed in the water through the filter screen cylinder, and the polyester filaments are separately collected through the claws and the staggered groove plates.

[0011] According to the above technical solution, the filtering mechanism includes a filtering box. A drainage end housing is fixedly connected to the outer side of the bottom end of the filtering box. A partition plate is fixedly connected to the inner wall in the middle of the filtering box. A water flow blade is rotatably connected to the bottom surface of the partition plate. A connecting shaft is fixedly connected to the axial center of the water flow blade. The top end of the connecting shaft is fixedly connected to a vortex disk. A vortex blade is fixedly connected to the top surface of the vortex disk. A cylinder disk is fixedly connected to the top surface of the vortex blade. A scraping net cylinder is fixedly connected to the top surface of the cylinder disk. A supporting ring is fixedly connected to the top end of the inner wall of the filtering box. A filter net cover is arranged inside the supporting ring. An upper discharge pipe and a lower discharge pipe are respectively fixedly connected to the front side of the filtering box.

[0012] According to the above technical solution, the top surface of the filtering box is fixedly connected to a discharge pipe. The drainage end housing is communicated with the inside of the filtering box. The filter net cover is rotatably connected to the scraping net cylinder. The upper discharge pipe is located above the lower discharge pipe. The ends of the upper discharge pipe and the lower discharge pipe away from the filtering box are both fixedly connected to a water tank. The bottom end of the connecting pipe is fixedly connected to the drainage end housing. When the water discharged from the discharge pipe enters the inside of the filtering box and reaches above the filter net cover, the dust is filtered. The water then enters the periphery of the vortex blade through the lower part of the filter net cover. At this time, the connecting pipe is in a water pumping state. The water below the partition plate is pumped through the connecting pipe, so that the water in the water tank enters the periphery of the water flow blade through the lower discharge pipe. When the water flows through the water flow blade, it will drive the water flow blade to rotate around the connection part of the partition plate, and the water is discharged through the connecting pipe. The rotation of the water flow blade drives the coaxial vortex blade to rotate, and the water around the vortex blade is discharged into the water tank through the upper discharge pipe, and the filtered dust is collected into the filter net cover, improving the purity of the recycled water in the water tank, reducing the number of times of water replacement, reducing water resource consumption, filtering and collecting the dust to prevent the blocked pipeline caused by the recycled water, and collecting the dust uniformly for convenient regular treatment.

[0013] The present invention provides a dust removal device for a polyester texturing machine, which has the following beneficial effects: In the present invention, by providing a dust removal mechanism, the sprayed water causes the floating polyester filaments and dust to settle and mix into the water, thereby playing a role in dust removal. At the same time, through the inclined strip guide, the influence of the attachment of polyester filaments on the air blowing direction can be reduced. When the baffle plate wipes across the nozzle, the attached polyester filaments will be removed, avoiding the polyester filaments blocking the nozzle and affecting the water spraying, resulting in a reduction in the dust removal effect. In the present invention, by providing a collection mechanism, the dust mixed with water and polyester filaments is separated by a filter net cylinder, and the polyester filaments are separately collected through a hook claw and a dislocation groove plate. The suction force of the branch air duct can adsorb the polyester filaments at the dislocation groove plate to avoid accumulation, so that the collected polyester filaments are stored in the discharge chute. When the materials in the discharge chute increase, they can be discharged in time, avoiding the need for manual treatment when the traditional equipment accumulates too much, improving the practicality of processing polyester filaments, and facilitating the recycling treatment of the collected polyester filaments. The present invention is provided with a filtering mechanism, which discharges the water into the water tank through the upper discharge pipe, and collects the filtered dust into the filter cover, thereby improving the purity of the return water in the water tank, reducing the number of water replacement times, and reducing water resource consumption. The filtered and collected dust avoids the return water from clogging the pipe, and the unified collection of dust is convenient for regular treatment. In addition, the vortex blades drive the drum disc to rotate, so that the drum disc drives the connected scraper drum to rotate, and the scraper drum rotates to fit the inner wall of the filter cover, so as to scrape off the dust attached to the inner wall of the filter cover, avoid the accumulation of dust in the filter cover that affects the water filtration efficiency, and maintain the dust removal effect for long-term use.

[0017] Please refer to Figures 1-9 , the embodiment of the present invention is: a dust removal device for a polyester filament texturing machine, including a support frame 1, a lower protective plate 2 is fixedly connected to the outer side of the lower half of the support frame 1, an upper protective plate 3 is fixedly connected to the outer side of the upper half of the support frame 1, a top plate 4 is fixedly connected to the top surface of the support frame 1, a dust removal mechanism 5 is arranged inside the support frame 1, a collection mechanism 6 is arranged behind the dust removal mechanism 5, a filtering mechanism 7 is arranged behind the collection mechanism 6, and a water pool 13 is arranged in the dust removal mechanism 5; The dust removal mechanism 5 includes an air inlet groove 51, an air outlet groove 53 is arranged above the air inlet groove 51, a branch air duct 52 is fixedly connected to the right end of the rear side of the air inlet groove 51, a water spraying groove 59 is fixedly connected to the front half of the inner wall of the water pool 13, two vertical plates 510 are slidably connected to the inner side of the water spraying groove 59, a buoyancy block 516 is fixedly connected to the bottom end of each vertical plate 510, an inclined block 511 is fixedly connected to the front side surface of the left vertical plate 510, two guide rails 512 are fixedly connected to the bottom surface of the water spraying groove 59, a baffle plate 513 is slidably connected between the two guide rails 512, a thin column 517 is fixedly connected to the left side surface of the baffle plate 513, a plurality of inclined strips 514 are fixedly connected to the bottom surface of the baffle plate 513 at equal intervals, and a plurality of spray heads 515 are fixedly connected to the bottom surface of the water spraying groove 59.

[0018] The left side of the lower guard plate 2 is provided with a water injection port 8. The rear side of the upper guard plate 3 is fixedly connected with a discharge chute 10. An installation groove 9 is formed on the right side of the upper guard plate 3. The bottom surface of the water tank 13 is fixedly connected with a water tank 11. A blower 12 is installed on the front side of the water tank 11. The right inner wall of the upper guard plate 3 is rotatably connected with a swing handle 54. Three peristaltic wheels 55 are rotatably connected to the outer edge of the swing handle 54. A peristaltic tube 56 is arranged on the outer side of the peristaltic wheel 55. The rear end of the peristaltic tube 56 is fixedly connected with a connecting tube 58. The front end of the peristaltic tube 56 is fixedly connected with a water outlet pipe 57. The water spray trough 59 is fixedly connected to the top end of the water outlet pipe 57. A strip groove is formed on the bottom surface of the baffle 513, and the strip groove corresponds to the position where the nozzle 515 is located. The air inlet groove 51 is fixedly connected with the blower 12. A spring piece is arranged at the rear side of the baffle 513, and the two ends of the spring piece are respectively fixedly connected with the bottom surface of the baffle 513 and the water spray trough 59. When the blower 12 is in the working state, the blower 12 sucks the polyester filaments and dust mixed in the ambient air into the blower 12 through the air inlet groove 51 connected to the air inlet, and then discharges the air containing polyester filaments and dust in the blower 12 into the air outlet groove 53. The air containing polyester filaments and dust in the air outlet groove 53 is introduced into the water tank 13. At this time, the swing handle 54 driven by an external motor makes the peristaltic wheel 55 squeeze the air in the peristaltic tube 56. The air pressure in the peristaltic tube 56 decreases, adsorbing the water in the connecting tube 58 to fill the pressure. As the peristaltic wheel 55 continues to rotate, the water in the peristaltic tube 56 continuously drains into the water spray trough 59 through the water outlet pipe 57. The water entering the water spray trough 59 sprays the water through the nozzle 515. The sprayed water makes the floating polyester filaments and dust settle and mix into the water, thus playing a role in dust removal. When the water level in the water tank 13 rises, the rising water surface drives the buoyancy block 516 to move upward and push the vertical plate 510. At this time, the vertical plate 510 will push the thin column 517, so that the thin column 517 drives the connected baffle 513 and the inclined strip 514 to slide along the guide rail 512 together. After the baffle 513 moves, the pressed spring piece is compressed and rubs against the end of the nozzle 515 to block the nozzle 515. At this time, the nozzle 515 no longer sprays water, resulting in a rapid drop in the water level of the water tank 13, and the buoyancy block 516 also drops and resets together. At this time, the nozzle 515 continues to spray water. The inclined strip 514 can guide to reduce the influence of polyester filament adhesion on the air blowing direction. When the baffle 513 rubs against the nozzle 515, the attached polyester filaments will be removed, avoiding the polyester filaments blocking the nozzle 515 and affecting the water spraying, resulting in a reduction in the dust removal effect.

[0019] The collecting mechanism 6 includes a filter screen cylinder 61 which is rotatably connected to the inner wall of the water tank 13. A claw 62 is fixedly connected to the outer surface of the filter screen cylinder 61. Rotating shaft seats 63 are rotatably connected to both the left and right sides of the filter screen cylinder 61. A rotary joint 64 is threadedly connected to the left side of the filter screen cylinder 61. A discharge pipe 65 is rotatably connected to the left side of the rotary joint 64. A water draining plate 67 is fixedly connected to the rear inner wall of the water tank 13. A plurality of staggered groove plates 66 are fixedly connected to the front side of the water draining plate 67. Touch rods 69 are fixedly connected to both the left and right sides of the water draining plate 67. A crank 68 is arranged between the filter screen cylinder 61 and the rotating shaft seat 63. A push plate 610 is fixedly connected between the two touch rods 69. A blocking plate 614 is arranged below the push plate 610. A filter plate 612 is fixedly connected to the top inner wall of the branch air duct 52. A blanking baffle 611 is rotatably connected to the inner wall of the discharge chute 10. A guide bar 613 is arranged directly below the blanking baffle 611. The filter screen cylinder 61 and the swing handle 54 are fixedly connected coaxially. The rotating shaft seat 63 is fixedly connected to the support frame 1. The crank 68 is fixedly connected to the filter screen cylinder 61. The blanking baffle 611 is fixedly connected to the touch rod 69. The blocking plate 614 slides through to the inner side of the top of the branch air duct 52. The bottom surface of the filter plate 612 is slidably connected to the top surface of the blocking plate 614. The top surface of the filter plate 612 is slidably connected to the push plate 610. A elastic spring is arranged on the bottom surface of the rear end of the touch rod 69, and the two ends of the elastic spring are respectively fixedly connected to the touch rod 69 and the water tank 13. The guide bar 613 is fixedly connected to the discharge chute 10. The polyester filaments floating in the water tank 13 pass through. The water is discharged through the discharge pipe 65 connected to the filter screen cylinder 61 through the rotary joint 64, driving the water flow. The polyester filaments floating in the water tank 13 flow towards the filter screen cylinder 61 along with the water flow. As the filter screen cylinder 61 rotates, the claw 62 is driven to pick up the polyester filaments floating on the water surface. The polyester filaments collected outside the filter screen cylinder 61 move relative to the staggered groove plates 66, and the polyester filaments are pushed onto the staggered groove plates 66 by the claw 62. The polyester filaments on the staggered groove plates 66 are adsorbed through the branch air duct 52 connected in the discharge chute 10 above the water draining plate 67. The polyester filaments pass above the water draining plate 67 to drain the excess water and are adsorbed on the filter plate 612. While the filter screen cylinder 61 rotates, it will drive the connected crank 68 to swing and push the touch rod 69 to slide along the inner wall of the water tank 13 and stretch the elastic spring. At this time, the movement of the touch rod 69 drives the blocking plate 614 to block the branch air duct 52. At the same time, the touch rod 69 drives the push plate 610 to push the polyester filaments on the filter plate 612 into the discharge chute 10. During this process, the touch rod 69 will push the blanking baffle 611 to flip. When the elastic spring causes the touch rod 69 to reset, the blanking baffle 611 also resets accordingly. The polyester filaments are separated from the dust mixed in the water through the filter screen cylinder 61, and the polyester filaments are separately collected through the claw 62 and the staggered groove plates 66. The suction force of the branch air duct 52 can adsorb the polyester filaments at the staggered groove plates 66 to avoid accumulation, so that the collected polyester filaments are stored in the discharge chute 10. After the materials in the discharge chute 10 increase, they can be discharged in time, avoiding the need to stop the machine and manually handle when the traditional equipment accumulates too much.Improve the practicality of processing polyester filaments and facilitate the recycling of collected polyester filaments.

[0020] The filtering mechanism 7 includes a filtering box 71. A drain end shell 74 is fixedly connected to the outer side of the bottom end of the filtering box 71. A partition plate 76 is fixedly connected to the middle inner wall of the filtering box 71. A water flow blade 75 is rotatably connected to the bottom surface of the partition plate 76. A connecting shaft is fixedly connected to the axial center of the water flow blade 75, and a vortex disk 77 is fixedly connected to the top end of the connecting shaft. A vortex blade 78 is fixedly connected to the top surface of the vortex disk 77. A cylinder disk 712 is fixedly connected to the top surface of the vortex blade 78. A scraping net cylinder 711 is fixedly connected to the top surface of the cylinder disk 712. A support ring 79 is fixedly connected to the top end inner wall of the filtering box 71. A filter screen cover 710 is arranged inside the support ring 79. An upper drain pipe 72 and a lower drain pipe 73 are respectively fixedly connected to the front side of the filtering box 71. The top surface of the filtering box 71 is fixedly connected to a discharge pipe 65. The drain end shell 74 is communicated with the inside of the filtering box 71. The filter screen cover 710 is rotatably connected to the scraping net cylinder 711. The upper drain pipe 72 is located above the lower drain pipe 73. The ends of the upper drain pipe 72 and the lower drain pipe 73 far from the filtering box 71 are both fixedly connected to a water tank 11. The bottom end of a connecting pipe 58 is fixedly connected to the drain end shell 74. When the water discharged from the discharge pipe 65 enters the inside of the filtering box 71 and reaches above the filter screen cover 710, the dust is filtered. The water then enters the area around the vortex blade 78 through the lower part of the filter screen cover 710. At this time, the connecting pipe 58 is in a water pumping state. The water below the partition plate 76 is pumped through the connecting pipe 58, so that the water in the water tank 11 enters the area around the water flow blade 75 through the lower drain pipe 73. The flowing water drives the water flow blade 75 to rotate around the connection part of the partition plate 76, and the water is discharged through the connecting pipe 58. The rotation of the water flow blade 75 drives the coaxial vortex blade 78 to rotate, and the water around the vortex blade 78 is discharged into the water tank 11 through the upper drain pipe 72, and the filtered dust is collected into the filter screen cover 710, improving the purity of the recycled water in the water tank 11, reducing the frequency of water replacement, reducing water resource consumption, filtering and collecting the dust to prevent the blocked pipeline caused by the backflow of the used water, and uniformly collecting the dust for convenient regular treatment. In addition, the rotation of the vortex blade 78 drives the cylinder disk 712 to rotate, and the cylinder disk 712 drives the connected scraping net cylinder 711 to rotate. The scraping net cylinder 711 rotates and fits against the inner wall of the filter screen cover 710 to scrape off the dust attached to the inner wall of the filter screen cover 710, preventing the dust accumulation in the filter screen cover 710 from affecting the water filtering efficiency and maintaining the dust removal effect during long-term use.

[0021] Working principle: When the fan 12 is in the working state, the fan 12 sucks the polyester filaments and dust mixed in the ambient air into the fan 12 through the air inlet groove 51 connected to the air inlet, and then discharges it into the air outlet groove 53 from the air outlet of the fan 12. The air containing polyester filaments and dust in the air outlet groove 53 is introduced into the water tank 13. At this time, the swing handle 54 driven by an external motor makes the peristaltic wheel 55 squeeze the air in the peristaltic tube 56. The air pressure in the peristaltic tube 56 decreases, adsorbing the water in the connecting tube 58 to fill the pressure. As the peristaltic wheel 55 continues to rotate, the water in the peristaltic tube 56 continuously drains into the water spraying groove 59 through the water outlet pipe 57. The water entering the water spraying groove 59 is sprayed out through the nozzle 515. The sprayed water causes the floating polyester filaments and dust to settle and mix into the water, thus playing a role in dust removal. When the water level in the water tank 13 rises, the rising water surface will drive the buoyancy block 516 to move upward and push the vertical plate 510. At this time, the vertical plate 510 will push the thin column 517, so that the thin column 517 drives the connected baffle plate 513 and the inclined strip 514 to slide along the guide rail 512 together. After the moved baffle plate 513 presses the spring piece and rubs against the end of the nozzle 515 to block the nozzle 515, the nozzle 515 no longer sprays water, resulting in a rapid drop in the water level of the water tank 13, and the buoyancy block 516 also drops and resets together. At this time, the nozzle 515 continues to spray water. The inclined strip 514 can guide to reduce the influence of the attachment of polyester filaments on the blowing direction of the air. When the baffle plate 513 rubs against the nozzle 515, the attached polyester filaments will be removed, avoiding the polyester filaments blocking the nozzle 515 and affecting the water spraying, resulting in a reduction in the dust removal effect; The polyester filaments floating in the water tank 13 pass through. The drain pipe 65 connected to the filter screen cylinder 61 through the rotary joint 64 discharges water to drive the water flow, so that the polyester filaments floating in the water tank 13 flow towards the filter screen cylinder 61 along with the water flow. As the filter screen cylinder 61 rotates, the hook claws 62 are driven to pick up the polyester filaments floating on the water surface. The polyester filaments collected outside the filter screen cylinder 61 move relative to the dislocation groove plate 66, and the polyester filaments are pushed onto the dislocation groove plate 66 through the hook claws 62. The polyester filaments on the dislocation groove plate 66 are adsorbed above the drain plate 67 through the branch air duct 52 connected in the discharge chute 10. The polyester filaments pass above the drain plate 67 to drain the excess water and are adsorbed on the filter plate 612. While the filter screen cylinder 61 rotates, it will drive the connected crank 68 to swing and push the pressure contact rod 69 to slide along the inner wall of the water tank 13 and stretch the elastic spring. At this time, the movement of the pressure contact rod 69 drives the baffle 614 to block the branch air duct 52. At the same time, the pressure contact rod 69 drives the push plate 610 to push the polyester filaments on the filter plate 612 into the discharge chute 10. During this process, the pressure contact rod 69 will push the blanking baffle 611 to turn over. When the elastic spring makes the pressure contact rod 69 reset, the blanking baffle 611 also resets accordingly. The polyester filaments are separated from the dust mixed in the water through the filter screen cylinder 61, and the polyester filaments are separately collected through the hook claws 62 and the dislocation groove plate 66. The suction of the branch air duct 52 can adsorb the polyester filaments at the dislocation groove plate 66 to avoid accumulation, so that the collected polyester filaments are stored in the discharge chute 10. After the materials in the discharge chute 10 increase, they can be discharged in time, avoiding the need to stop the machine manually for processing when traditional equipment accumulates too much, improving the practicability of processing polyester filaments, and facilitating the recycling treatment of the collected polyester filaments; When the water discharged from the drain pipe 65 enters the inside of the filter box 71, it enters above the filter screen cover 710 to filter the dust, and the water enters around the eddy current blade 78 below the filter screen cover 710. At this time, the connecting pipe 58 is in the state of pumping water, and the water below the partition plate 76 is pumped through the connecting pipe 58, so that the water in the water tank 11 enters around the water flow blade 75 through the lower drain pipe 73. The water flowing through the water flow blade 75 will drive the water flow blade 75 to rotate around the connection of the partition plate 76, and the water is discharged through the connecting pipe 58. The rotation of the water flow blade 75 drives the coaxial eddy current blade 78 to rotate, and the water around the eddy current blade 78 is discharged into the water tank 11 through the upper drain pipe 72, and the filtered dust is collected into the filter screen cover 710, improving the purity of the recycled water in the water tank 11, reducing the number of water replacements, reducing water resource consumption, filtering and collecting the dust to avoid blocking the pipeline with the recycled water, collecting the dust uniformly for convenient regular treatment. In addition, the rotation of the eddy current blade 78 drives the cylinder disc 712 to rotate, and the cylinder disc 712 drives the connected scraping net cylinder 711 to rotate. The scraping net cylinder 711 rotates to fit the inner wall of the filter screen cover 710 to scrape off the dust attached to the inner wall of the filter screen cover 710, avoiding the accumulation of dust in the filter screen cover 710 and affecting the water filtering efficiency, and maintaining the dust removal effect for long-term use.
