Description

Technical Field

[0001] This invention relates to the field of dyeing and printing wastewater treatment technology, specifically to a waste textile recycling water recycling system. Background Technology

[0002] During the processing of waste textiles, processes such as bleaching and dyeing generate a large amount of wastewater. This wastewater contains organic pollutants and impurities such as dyeing lint. Direct discharge of this wastewater will cause environmental pollution and waste of water resources. Therefore, it is necessary to recycle the wastewater from waste textiles.

[0003] Patent application number 202110925294.9 discloses an environmental protection dyeing and printing wastewater recycling device, specifically disclosing that an electrolyzed impurity is filtered by a filter plate that is flipped. When flipping the filter plate, the device needs to be stopped for a short time to prevent impurities from entering the system. Furthermore, due to the varying heights of impurities in the water, the impurities cannot be evenly distributed on the filter screen. After flipping the filter plate, the quality of dyeing and printing lint will adhere to the mesh areas with fewer impurities, resulting in poor cleaning effect on the filter plate. Summary of the Invention

[0004] The purpose of this invention is to provide a water recycling system for waste textiles.

[0005] The technical problem solved by this invention is to address the issue of poor wastewater treatment efficiency caused by the need to shut down the machine when cleaning or replacing filter plates in the prior art.

[0006] The present invention can be achieved through the following technical solution: a waste textile recycling water circulation system, including a water circulation tank, with inlet pipes and outlet pipes symmetrically arranged on both sides of the water circulation tank, a filter screen installed inside the water circulation tank and located between the inlet pipes and outlet pipes, a first winding assembly installed at the bottom of the water circulation tank, and a second winding assembly installed at the top of the water circulation tank, the first winding assembly and the second winding assembly being fixedly connected to both ends of the filter screen respectively.

[0007] A further technical improvement of the present invention is that: a first guide component is fixed at the top inside the water circulation tank, and a second guide component is fixed at the top outside the water circulation tank; the second guide component and the second winding component are at the same height.

[0008] A further technical improvement of the present invention is that: the first winding assembly includes a winding roller, which is rotatably arranged inside the water circulation tank and is driven by a drive motor.

[0009] A further technical improvement of the present invention is that: a limiting rod is fixed inside the water circulation tank, a receiving cavity is left between the limiting rod and the winding roller, the filter screen passes through the receiving cavity, and the filter screen is wound on the winding roller.

[0010] A further technical improvement of the present invention is that a drying component is provided between the second guiding component and the second winding component. The drying component includes a drying and suction box, with side bases symmetrically installed on both sides of the drying and suction box. The output end of the drying and suction box is provided with a drying and suction mesh and a dust suction hood.

[0011] A further technical improvement of the present invention is that: a side groove is provided on the side of the side base, an internal telescopic rod is fixed inside the side groove, an end seat is fixed at the end of the internal telescopic rod, and the side of the end seat is fixedly connected to the second winding assembly.

[0012] A further technical improvement of the present invention is that the second winding assembly includes an end roller, which is driven by an end motor, and the end of the filter screen is fixed on the end roller.

[0013] A further technical improvement of the present invention is that: the filter screen includes a perforated plate and a flat plate, the perforated plate and the flat plate are fixedly connected, the end of the perforated plate is connected to an end roller, and the end of the flat plate is connected to a take-up roller.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This application fixes the first winding assembly and the second winding assembly to both ends of the filter screen respectively, so that the first winding assembly can be used to wind up one end of the filter screen and the second winding assembly can be used to wind up the other end of the filter screen. When the second winding assembly is used to wind up the filter screen, the filter screen containing impurities can be wound up, thereby allowing the filter screen located inside the water circulation tank to be directly replaced. In this process, the filter screen can be replaced without stopping the machine, ensuring the efficiency of water purification.

[0016] 2. This application uses a drying component to dry the collected filter screen, thereby separating the flocculent impurities from the mesh. When the dust collection hood is in operation, the flocculent impurities are adsorbed, thus cleaning the filter screen. This allows the filter screen to be directly recycled, saving the time required to replace the filter screen and ensuring the efficiency of water purification.

[0017] 3. By using a flat plate, this application separates the water circulation tank after the perforated plate is used, preventing impurities in the water from entering the other end of the water circulation tank and ensuring the effect of wastewater purification. That is, when in use, wastewater input is stopped and the wastewater is blocked by the flat plate until the perforated plate re-enters the water circulation tank. Attached Figure Description

[0027] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0028] Please see Figure 1-7 As shown, the waste textile recycling water recycling system includes a water recycling tank 21, wherein an inlet pipe 20 is connected to the side of the water recycling tank 21, and an outlet pipe assembly is provided at the end of the water recycling tank 21 away from the inlet pipe 20. The dyeing wastewater enters the interior of the water recycling tank 21 through the inlet pipe 20 and is then discharged through the outlet pipe assembly.

[0029] In order to purify textile wastewater, a filtration mechanism is installed inside the water circulation tank 21. The wastewater entering through the inlet pipe 20 is filtered by the filtration mechanism to obtain preliminarily purified wastewater and remove impurities from the wastewater.

[0030] Specifically, the water outlet pipe assembly includes a drain pipe 22, which is connected to the side of the water circulation tank 21. The drain pipe 22 is located away from the inlet pipe 20 and is used to discharge the filtered wastewater. Two output pipes are connected to the drain pipe 22, namely a circulation pipe 23 and a branch pipe 25. The circulation pipe 23 is used to discharge the treated wastewater, while the branch pipe 25 is connected to the re-purification pipe 24. This allows the wastewater to enter the interior of the water circulation tank 21 through the re-purification pipe 24 for secondary purification when the wastewater purification effect is poor. During this process, the speed of water entering through the inlet pipe 20 can be controlled, and water inside the water circulation tank 21 can be drawn out by a water pump and left inside the water circulation tank 21 for secondary purification using its internal filtration mechanism.

[0031] Furthermore, the filtration mechanism includes a filter screen 5, which is used to separate the inlet pipe 20 and the outlet pipe 22 to filter the wastewater entering the water circulation tank 21. The flocculent impurities in the wastewater are separated by the filter screen 5. The flocculent impurities will flow from the inlet pipe 20 to the outlet pipe 22 due to the direction of water flow, and the flocculent impurities will be distributed on the filter screen 5.

[0032] Because the filter screen 5 can be cleaned without stopping the machine, it can be replaced and cleaned by winding it up. Therefore, in this application, a first winding assembly 1 is provided at the bottom of the water circulation tank 21, on which the filter screen 5 is wound up. A first guide assembly 2 is provided at the top of the water circulation tank 21. The first winding assembly 1 is used to wind up the filter screen 5, and the first guide assembly 2 is used to initially guide the filter screen 5, so that the filter screen 5 can be tautly placed inside the water circulation tank 21. A second guide assembly is provided laterally on the outside of the water circulation tank 21. Component 3 and the second winding component 6, in this application, guide the filter screen 5 through the first guiding component 2, and then guide the filter screen 5 further through the second guiding component 3 before winding it up through the second winding component 6. During this process, the flocculent impurities adhering to the mesh of the filter screen 5 can be collected uniformly. In use, the filter screen 5 can be directly wound up by the second winding component 6, allowing the filter screen 5 to be replaced without stopping the machine. At the same time, during use, the flocculent impurities can be evenly distributed above the filter screen 5, thereby achieving stability in the interception efficiency of the filter screen 5.

[0033] In order to clean the impurities on the filter screen 5 after it has been wound up by the second winding assembly 6, a drying assembly 4 is provided between the second guiding assembly 3 and the second winding assembly 6. The drying assembly 4 is used to dry the wound filter screen 5 so that the moisture in the flocculent impurities is dried. After that, the flocculent impurities are adsorbed by an adsorption device to achieve automatic cleaning of the filter screen 5.

[0034] Specifically, the first winding assembly 1 and the first guiding assembly 2 have the same mechanism, and the second guiding assembly 3 and the second winding assembly 6 have the same structure. Taking the first winding assembly 1 as an example, the first winding assembly 1 includes a winding roller 8, which is rotatably installed inside the water circulation tank 21. A winding wheel 9 is installed on the winding roller 8. A drive motor 12 is fixedly installed inside the water circulation tank 21, and a drive wheel 11 is provided at the output end of the drive motor 12. A drive belt 10 is provided between the drive wheel 11 and the winding wheel 9. That is, the drive motor 12 drives the drive wheel 11 to rotate, so that under the transmission action of the drive belt 10, the winding wheel 9 is driven to rotate, thereby driving the winding roller 8 to rotate, realizing the winding and unwinding of the filter screen 5.

[0035] In order to ensure that the filter screen 5 is pressed tightly onto the take-up roller 8, a limiting rod 7 is provided on the side of the take-up roller 8. The limiting rod 7 is fixed inside the water circulation tank 21. A certain gap is left between the limiting rod 7 and the take-up surface of the take-up roller 8 to allow the filter screen 5 to be placed.

[0036] The second guiding component 3 and the second winding component 6 have the same structure. In this application, the second winding component 6 is taken as an example. The second winding component 6 includes an end motor 18, which drives the end roller 19. That is, the end motor 18 directly drives the end roller 19 to rotate, so as to realize the winding of the filter screen 5 or the guidance of the filter screen 5.

[0037] The end motor 18 on the second guide assembly 3 is fixed at the fixed point, while the end motor 18 on the second winding assembly 6 is mounted on the drying assembly 4.

[0038] Specifically, the drying assembly 4 includes an integrated drying and suction box 14 and a side base 16. The side base 16 is symmetrically fixed on both sides of the integrated drying and suction box 14, that is, the integrated drying and suction box 14 and the side base 16 are in an "n" shape. The filter screen 5 passes through the side of the side base 16. An end roller 19 is installed on the side of the side base 16. The end roller 19 is rotated by the end motor 18. The filter screen 5 passes through the bottom of the integrated drying and suction box 14 and is dried by the integrated drying and suction box 14. Then, the integrated drying and suction box 14 adsorbs the dried flocculent impurities on the filter screen 5 to clean the filter screen 5.

[0039] Specifically, to maximize the drying efficiency of the filter screen 5, a side groove 17 is provided on the side of the side base 16. An internal telescopic rod 15 is fixed inside the side groove 17, and an end seat is fixed to the output end of the internal telescopic rod 15. An end motor 18 is installed on the side of the end seat. The internal telescopic rod 15 is used to adjust the movement of the end seat and control the position of the end motor 18. At this time, the position of the end roller 19 can be controlled. When the filter screen 5 is initially used, the filter screen 5 is fully inserted into the water circulation box 21. If the filter screen 5 needs to be replaced, the internal telescopic rod 15 is used to control the position of the end roller 19, so that the filter screen 5 is stretched to the bottom of the drying and suction box 14. The drying and suction box 14 is used to clean the filter screen 5. After cleaning, when the filter screen 5 is replaced again, the end motor 18 is used to control the rotation of the end roller 19 to achieve the winding process of the filter screen 5.

[0040] The bottom of the drying and suction box 14 is provided with a drying and suction mesh 13, and a dust suction hood 26 is provided on the side of the drying and suction mesh 13. The drying and suction mesh 13 is provided with a drying heating wire, which is used to preliminarily dry the flocculent impurities on the filter screen 5. Then, when the filter screen 5 rotates onto the dust suction hood 26, the dust suction pump is used to adsorb the preliminarily dried flocculent impurities, thereby achieving the initial cleaning of the filter screen 5.

[0041] The filter screen 5 includes a perforated plate 27 and a flat plate 28, which are fixedly connected. The flat plate 28 is located at the bottom of the perforated plate 27. When the filter screen 5 is fully replaced, that is, when the perforated plate 27 is used up, the flat plate 28 is used to separate the incoming water. This can prevent wastewater containing flocculent impurities from flowing into the next system and also prevent flocculent impurities from blocking the mesh. The perforated plate 27 and the flat plate 28 are both soft boards that can be rolled up. After the flocculent impurities on the perforated plate 27 are fully adsorbed, the drive motor 12 is reversed to retract the filter screen 5. During this process, the machine can be stopped for a short time to replace the filter screen 5.

[0042] In this application, the height of the first guide component 2 is lower than that of the second guide component 3, and the heights of the second guide component 3 and the second winding component 6 are flush. This process is to allow impurities that can be adhered to the filter screen 5 to be naturally filtered out of moisture when passing between the height of the first guide component 2 and the second guide component 3. Then, the second guide component 3 is dried when passing through the second winding component 6, which can prevent fibrous impurities from falling naturally into the interior of the water circulation tank 21 during drying.

[0043] In use, textile wastewater is first introduced into the water circulation tank 21 through the inlet pipe 20. Then, the flocculent impurities in the flowing wastewater are filtered through the filter screen 5. The filtered wastewater is then discharged through the drain pipe 22. If there are too many impurities in the discharged wastewater, it enters the re-purification pipe 24 through the branch pipe 25 for re-filtration. If there are too few impurities in the discharged wastewater, it is discharged through the circulation pipe 23 and enters the next treatment process.

[0044] If there are too many flocculent impurities on the filter screen 5, affecting its operation, the extension of the internal telescopic rod 15 is used to control the end seat to slide inside the side groove 17 until the control end roller 19 moves laterally to the position of the dust collection hood 26. During this process, the drying and suction mesh 13 is used to dry the moving filter screen 5. At this time, the drive motor 12 drives the drive wheel 11 to rotate, thereby causing the winding roller 8 to rotate under the action of the drive belt 10. The winding roller 8 releases part of the filter screen 5, so that the filter screen 5 is located between the water inlet pipe 20 and the drain pipe 22 to filter the wastewater. During this process, the filter screen 5 can be replaced without stopping the machine.

[0045] If the filter screen 5 in the second part is clogged with flocculent impurities, the dust suction hood 26 is used to adsorb the flocculent impurities. Then, under the rotation of the end motor 18, the end roller 19 is used to wind up the cleaned filter screen 5. This process continues until the flat plate 28 on the winding roller 8 enters the interior of the water circulation box 21. At this time, the flocculent impurities on the mesh plate 27 are all adsorbed by the dust suction hood 26. Then, the drive motor 12 is reversed and the winding roller 8 is used to rewind the cleaned filter screen 5.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
