Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and more particularly to a self-cleaning industrial wastewater treatment system. Background Technology

[0002] In industrial production processes, wastewater typically contains a large number of suspended particles, fibers, oil, and other impurities. If discharged directly without effective treatment, it will cause serious environmental pollution. Therefore, industrial wastewater treatment systems generally use physical filtration as a pretreatment step to remove large particulate impurities and protect the normal operation of subsequent treatment units (such as membrane separation, biochemical reactors, etc.).

[0003] However, traditional filtration devices mostly use single-chamber or fixed filter element structures. During operation, the filter pores are easily clogged by impurities, leading to a rapid decline in filtration efficiency, an increase in differential pressure, and even system shutdown. To restore filtration performance, manual disassembly, cleaning, or replacement of the filter element is usually required. This is not only cumbersome and costly to maintain, but also forces the entire process to be interrupted during cleaning, seriously affecting the continuity of production and processing efficiency.

[0004] Although some existing filtration devices have self-cleaning functions, such as those that regenerate the filter screen through backwashing, scraping, or air blowing, most still have the following shortcomings: the cleaning process and the filtration process cannot be carried out in parallel, and a short shutdown is still required to switch operating conditions; and impurities are not thoroughly removed, and residues are easily caked in the filter pores, resulting in significant performance degradation after long-term use. Summary of the Invention

[0005] This application aims to at least partially address one of the technical problems in the related art.

[0006] Therefore, the purpose of this application is to provide a self-cleaning industrial wastewater treatment system. By arranging multiple filter shells in a circumferential array on a diversion pipe and driving them to rotate periodically by a drive mechanism, some filter shells filter wastewater while the others are cleaned simultaneously, thereby achieving continuous and efficient filtration without stopping the system and significantly improving the continuity of system operation and treatment efficiency.

[0007] To achieve the above objectives, the first aspect of this application proposes a self-cleaning industrial wastewater treatment system, comprising a wastewater impurity removal tank, an inlet pipe and an outlet pipe disposed on the wastewater impurity removal tank, and a cleaning assembly disposed within the wastewater impurity removal tank. The cleaning assembly includes a diversion pipe rotatably disposed within the wastewater impurity removal tank; filter shells communicating with the diversion pipe are mounted in a circular array on the outer surface of the diversion pipe; a water storage tank fixedly connected to the inlet pipe is rotatably disposed on the diversion pipe; multiple drainage troughs communicating with the water storage tank are formed on the outer circumference of the water storage tank; a collection trough not communicating with the water storage tank is disposed on the top of the water storage tank; a spiral cleaning rod is rotatably disposed within the collection trough; a driving mechanism is disposed on one side of the wastewater impurity removal tank; an extrusion mechanism is disposed on the top surface of the wastewater impurity removal tank and directly above the diversion pipe; and scraping mechanisms are disposed within each of the multiple filter shells.

[0008] In addition, the self-cleaning industrial wastewater treatment system proposed in this application may also have the following additional technical features: In one embodiment of this application, the driving mechanism includes a transmission cylinder that is rotatably sealed on the wastewater impurity removal tank; a drive motor is fixedly installed on the surface of the wastewater impurity removal tank and on one side of the transmission cylinder; a drive gear is fixedly installed at the output end of the drive motor; a first toothed groove that meshes with the drive gear is formed on the surface of the transmission cylinder; a transmission gear is fixedly installed at one end of the spiral cleaning rod inside the transmission cylinder; and a second toothed groove that meshes with the transmission gear is formed on the inner surface of the transmission cylinder.

[0009] In one embodiment of this application, the inner wall of the transmission cylinder is sloped, and the inner diameter of the end of the transmission cylinder near the wastewater impurity removal box is smaller than the inner diameter of the other end of the transmission cylinder.

[0010] In one embodiment of this application, a collection box is fixedly installed on the surface of the wastewater impurity removal box and below the transmission cylinder, and a foreign matter removal area is reserved between the transmission gear and the collection tank.

[0011] In one embodiment of this application, the extrusion mechanism includes a treatment box slidably disposed on the wastewater impurity removal box; an electric telescopic rod for lifting and lowering the treatment box is fixedly installed on the treatment box; a blower frame is fixedly installed on the inner side of the bottom end of the treatment box; multiple partition plates are fixedly installed inside the blower frame; a gas distribution pipe is fixedly installed between two adjacent partition plates; a gas supply pipe is fixedly installed at one end of the multiple gas distribution pipes; and a gas supply component is fixedly installed at one end of the gas supply pipe.

[0012] In one embodiment of this application, a control valve is provided on each of the plurality of gas distribution pipes, and the gas supply component is fixedly installed on the processing box.

[0013] In one embodiment of this application, the processing box is located above the filter housing, and a sealing element is provided on the side of the blower frame near the filter housing.

[0014] In one embodiment of this application, the scraping mechanism includes movable grooves formed on both sides of the inner wall of the filter housing; a cleaning plate is slidably disposed inside the filter housing; movable blocks are fixedly installed at both ends of the cleaning plate and slidably disposed in the movable grooves; a locking groove is formed on the movable block; a positioning block is slidably disposed inside the filter housing; a return spring is fixedly installed on one side of the positioning block; a transmission rope connected to the positioning block is slidably disposed inside the positioning block; and a trigger rod is fixedly installed on the filter housing.

[0015] In one embodiment of this application, the bottom surface of the positioning block near the locking groove is designed as a slope.

[0016] In one embodiment of this application, one end of the trigger rod is located outside the filter housing, and one end of the transmission rope is connected to the end of the trigger rod located inside the filter housing.

[0017] The beneficial effects of the self-cleaning industrial wastewater treatment system in this application embodiment are as follows: 1. By arranging multiple filter housings in a circumferential array on the diversion pipe and controlling their periodic rotation by a drive mechanism, the filtration and cleaning stations can be alternated. This allows some filter housings to continuously filter wastewater while others are simultaneously cleaned, achieving continuous and efficient filtration without shutdown and significantly improving the continuity and efficiency of the system.

[0018] 2. High-pressure airflow is applied to the inside of the filter housing through the extrusion mechanism, performing a combined "back-blowing + extrusion" action on the filter pores. This removes attached impurities from the filter pores and pushes them into the housing cavity. Subsequently, the scraping mechanism automatically unlocks after the air blowing is completed and slides down the inner wall of the filter housing under gravity, scraping away residual dirt. The impact vibration generated when it touches the bottom further loosens stubborn impurities, achieving a deep cleaning of the filter housing and preventing filter pore clogging and performance degradation. The two mechanisms work together to achieve a highly reliable and thorough self-cleaning function.

[0019] 3. During cleaning, the extrusion mechanism presses down the trigger rod to automatically release the cleaning plate. After cleaning, the plate rotates with the filter housing to the filtration station. Under the action of water flow and gravity, the positioning block and locking groove are precisely engaged, achieving a reliable reset without power or electricity. This mechanism has a simple structure, rapid response, and low failure rate, ensuring that each filter unit can be accurately positioned and work stably in each cycle.

[0020] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0023] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The self-cleaning industrial wastewater treatment system of this application embodiment will now be described with reference to the accompanying drawings.

[0025] like Figures 1-7 As shown in the figure, the self-cleaning industrial wastewater treatment system of this application includes a wastewater impurity removal tank 100, an inlet pipe 200 and an outlet pipe 300 disposed on the wastewater impurity removal tank 100, and a cleaning assembly 400 disposed inside the wastewater impurity removal tank 100. The cleaning assembly 400 includes a diversion pipe 401 rotatably disposed inside the wastewater impurity removal tank 100; filter shells 402, communicating with each other, are mounted in a circular array on the outer surface of the diversion pipe 401; and the diversion pipe 401 is rotatably fixedly connected to the inlet pipe 200. The water storage tank 403 has multiple drainage troughs 404 connected to it on its outer circular surface; a collection trough 405 not connected to the water storage tank 403 is provided on the top of the water storage tank 403; a spiral cleaning rod 406 is rotatably installed in the collection trough 405; a driving mechanism 500 is provided on one side of the wastewater impurity removal tank 100; an extrusion mechanism 600 is provided on the top surface of the wastewater impurity removal tank 100 and directly above the diversion pipe 401; and a scraping mechanism 700 is provided in each of the multiple filter shells 402.

[0026] It should be noted that, in order to avoid the filtered water affecting the rinsing of the filter housing 402 during wastewater filtration, the highest water level in the wastewater impurity removal tank 100 should not exceed the height of the diversion pipe 401. The inlet pipe 200 is used for water flow pressure during filtration, while the outlet pipe 300 relies on the natural flow of water. Therefore, the drainage speed is related to the diameter of the outlet pipe 300. However, an active water pump or suction pump can be added to increase the water flow speed and prevent the water level in the wastewater impurity removal tank 100 from being too high.

[0027] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the drive mechanism 500 includes a transmission cylinder 501 rotatably sealed on the wastewater removal tank 100; a drive motor 502 is fixedly installed on the surface of the wastewater removal tank 100 and on one side of the transmission cylinder 501; a drive gear 503 is fixedly installed at the output end of the drive motor 502; a first tooth groove 504 that meshes with the drive gear 503 is opened on the surface of the transmission cylinder 501; a transmission gear 505 is fixedly installed at one end of the spiral cleaning rod 406 inside the transmission cylinder 501; and a second tooth groove 506 that meshes with the transmission gear 505 is opened on the inner surface of the transmission cylinder 501.

[0028] It should be noted that the drive motor 502 is a stepper motor. After each rotation, a filter housing 402 will be positioned directly above the diverter tube 401. Furthermore, the drive motor 502 has an automatic locking function after rotation to ensure the stability of the diverter tube 401 after the drive motor 502 drives it to rotate.

[0029] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the inner wall of the transmission cylinder 501 is inclined, and the inner diameter of the end of the transmission cylinder 501 near the wastewater impurity removal box 100 is smaller than the inner diameter of the other end of the transmission cylinder 501.

[0030] It should be noted that one end of the transmission cylinder 501 is fixedly connected to one end of the diversion pipe 401, so that the diversion pipe 401 can rotate synchronously when the transmission cylinder 501 rotates. The transmission cylinder 501 is also sealed and rotatedly connected to the wastewater removal tank 100, which can prevent water in the wastewater removal tank 100 from flowing out through the space between the transmission cylinder 501 and the wastewater removal tank 100.

[0031] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, a collection box is fixedly installed on the surface of the wastewater impurity removal box 100 and below the transmission cylinder 501, and a foreign matter removal area is reserved between the transmission gear 505 and the collection trough 405.

[0032] It should be noted that the foreign object removal area between the transmission gear 505 and the collection tank 405 is to prevent obstruction or contact between foreign objects and the transmission gear 505 during discharge, thus limiting the discharge of foreign objects. A discharge trough is fixedly installed on the water storage tank 403, inclined below the collection tank 405, to guide foreign objects discharged from the collection tank 405 into the collection box, reducing contact between foreign objects and the drive mechanism 500 and minimizing their impact. Furthermore, the collection box and the wastewater removal tank 100 are connected by a quick-release structure to facilitate the cleaning of foreign objects from the collection box.

[0033] In one embodiment of this application, such as Figure 6 and Figure 7 As shown, the extrusion mechanism 600 includes a treatment box 601 slidably disposed on the wastewater impurity removal box 100; an electric telescopic rod 602 for raising and lowering the treatment box 601 is fixedly installed on the treatment box 601; a blower frame 603 is fixedly installed on the inner side of the bottom end of the treatment box 601; a plurality of partition plates 604 are fixedly installed inside the blower frame 603; a gas distribution pipe 605 is fixedly installed between two adjacent partition plates 604; a gas supply pipe 606 is fixedly installed at one end of the plurality of gas distribution pipes 605; and a gas supply component 607 is fixedly installed at one end of the gas supply pipe 606.

[0034] It should be noted that when cleaning the filter housing 402, the output end of the electric telescopic rod 602 needs to be moved down slowly. When it is fully extended, that is, after the processing box 601 completely covers the filter housing 402, the electric telescopic rod 602 can be retracted to facilitate cleaning the next filter housing 402.

[0035] In one embodiment of this application, such as Figure 6 and Figure 7 As shown, each of the multiple gas distribution pipes 605 is equipped with a control valve, and the gas supply component 607 is fixedly installed on the processing box 601.

[0036] It should be noted that, in order to ensure the cleaning force of the filter holes on the filter housing 402, the blower frame 603 is divided into sections, and then multiple control valves are used to open the multiple control valves in sequence. When one control valve is opened, another control valve is closed, so that the gas at the same pressure can better flush the filter holes.

[0037] In one embodiment of this application, such as Figure 6 and Figure 7 As shown, the processing box 601 is located above the filter housing 402, and the blower frame 603 is provided with a sealing element on the side near the filter housing 402.

[0038] It should be noted that the seal is used to improve the sealing between the blower frame 603 and the filter housing 402. The seal is used to reduce the gap between the two. Even if there is a certain amount of air leakage, the amount of leakage is limited and will not affect the initial cleaning of the filter holes on the filter housing 402.

[0039] In one embodiment of this application, such as Figure 4 and Figure 7 As shown, the scraping mechanism 700 includes movable grooves 701 formed on both sides of the inner wall of the filter housing 402; a cleaning plate 702 is slidably disposed inside the filter housing 402; movable blocks 703 are fixedly installed at both ends of the cleaning plate 702 and slidably disposed in the movable grooves 701; a locking groove 704 is formed on the movable block 703; a positioning block 705 is slidably disposed inside the filter housing 402; a return spring 706 is fixedly installed on one side of the positioning block 705; a transmission rope 707 connected to the positioning block 705 is slidably disposed inside the positioning block 705; and a trigger rod 708 is fixedly installed on the filter housing 402.

[0040] It should be noted that a counterweight is appropriately added to the cleaning plate 702 to improve its mass and make it move more smoothly downwards. In order to prevent foreign objects from entering the moving groove 701 during filtration and causing them to obstruct the downward movement of the cleaning plate 702 or the moving block 703, the moving groove 701 is designed in a trapezoidal shape with a smaller opening on the side near the cleaning plate 702, which can greatly reduce the amount of foreign objects entering. At the same time, a flexible rubber strip is provided at the opening on the side near the cleaning plate 702, so that the moving block 703 is not restricted when it moves. After moving, due to its automatic plasticity, it can quickly reset to form a relatively sealed area, further blocking foreign objects.

[0041] In one embodiment of this application, such as Figure 4 and Figure 7 As shown, the bottom surface of the positioning block 705 near the locking groove 704 is designed with a slope.

[0042] It should be noted that the bottom of the processing box 601 is provided with a through groove, and the transmission rope 707 is horizontally arranged in the through groove. One end of the transmission rope 707 is fixedly connected to one side of the through groove, and the transmission rope 707 is slidably connected to the other side of the through groove. When the processing box 601 moves the transmission rope 707 down to above the trigger rod 708, the trigger rod 708 restricts the transmission rope 707, thereby causing the transmission rope 707 to pull the positioning block 705.

[0043] In one embodiment of this application, such as Figure 4 and Figure 7 As shown, one end of the trigger rod 708 is located outside the filter housing 402, and one end of the transmission rope 707 is connected to the end of the trigger rod 708 located inside the filter housing 402.

[0044] Specifically, in the actual treatment process, industrial wastewater enters the storage tank 403 through the inlet pipe 200, and then flows into the diversion pipe 401 connected to it through the drain trough 404. The diversion pipe 401 has multiple filter shells 402 arranged in a circumferential array. Under pressure, the wastewater enters the filter shells 402 located below the storage tank 403 from the diversion pipe 401. After filtration, it flows into the wastewater impurity removal tank 100 and is finally discharged from the outlet pipe 300. During this process, impurities are trapped inside the filter shells 402. When the filter housing 402 needs to be rinsed, the output end of the drive motor 502 is first rotated by the control switch. The rotation of the output end of the drive motor 502 will drive the drive gear 503 to rotate. Since the drive gear 503 meshes with the first tooth groove 504, the rotation of the output end of the drive motor 502 will drive the transmission cylinder 501 to rotate. The rotation of the transmission cylinder 501 will drive the diversion pipe 401 to rotate. Then, after a period of time, the transmission cylinder 501 will rotate multiple filter housings 402 to the top of the diversion pipe 401 in turn. When a filter housing 402 rotates to a position directly below the processing box 601, the electric telescopic rod 602 drives the processing box 601 to move downwards until the seal at the bottom of the air blowing frame 603 is tightly fitted with the upper edge of the filter housing 402, forming a closed cleaning chamber. Then, the air supply component 607 is activated, and compressed air enters each air distribution pipe 605 sequentially through the air supply pipe 606, causing the high-pressure gas to blow on the filter holes on the filter housing 402, thereby blowing away the impurities in the filter holes on the filter housing 402. This airflow can peel off the impurities from the filter holes and also "squeeze" them in and push them into the cavity of the filter housing 402 below. As the electric telescopic rod 602 moves, the air blowing frame 603 moves downwards, thereby allowing the air blowing frame 603 to perform a comprehensive initial cleaning of the filter housing 402, preparing for subsequent scraping and collection. Under normal filtration conditions, the positioning block 705, under the action of the return spring 706, has its inclined end embedded in the locking groove 704 on the moving block 703 of the cleaning plate 702, fixing the cleaning plate 702 to the top of the filter housing 402. When the extrusion mechanism 600 continues to move downward, it will squeeze the trigger rod 708, thereby pulling the transmission rope 707. The transmission rope 707 pulls the positioning block 705 backward against the elastic force of the return spring 706, causing it to disengage from the locking groove 704. The cleaning plate 702, now unrestrained, moves backward. 02 Under the action of gravity, it slides down along the moving groove 701, scraping all the impurities in its path to the bottom of the filter shell 402. When it touches the bottom, a certain collision occurs, and the vibration generated by the collision causes the foreign objects to fall into the collection groove 405 below. When the subsequent drive mechanism 500 runs, it will drive the transmission gear 505 to rotate through the second tooth groove 506. The rotation of the transmission gear 505 will drive the spiral cleaning rod 406 to rotate, and then the spiral cleaning rod 406 will transmit the foreign objects in the collection groove 405 out and drop them into the collection box. After the cleaning operation is completed, the cleaned filter housing 402 will continue to rotate in the subsequent process. At this time, the trigger rod 708 is no longer squeezed. Under the action of the return spring 706, the positioning block 705 returns to the initial position. When the filter housing 402 rotates to directly below the diversion pipe 401, its interior is connected to the drain tank 404. Under the combined action of water flow impact and the weight of the filter housing, the cleaning plate 702 begins to move towards the positioning block 705. During the movement, the cleaning plate 702 squeezes the positioning block 705, causing it to retract. When the locking groove 704 on the moving block 703 moves to the corresponding position of the positioning block 705, the positioning block 705 pops out under the push of the return spring 706 and locks into the locking groove 704, thereby achieving reliable positioning of the moving block 703 and the cleaning plate 702. This mechanism ensures that the cleaning mechanism can be accurately reset after each working cycle, preparing for the next cleaning operation.

[0045] In summary, the self-cleaning industrial wastewater treatment system of this application embodiment arranges multiple filter housings 402 in a circumferential array on the diversion pipe 401, and controls their periodic rotation by the drive mechanism 500 to achieve alternating operation of the filtration and cleaning stations. Thus, while some filter housings 402 are continuously filtering wastewater, other filter housings are simultaneously cleaned, achieving continuous and efficient filtration without stopping the system, significantly improving the continuity of system operation and treatment efficiency.

[0046] High-pressure airflow is applied to the inside of the filter housing 402 by the extrusion mechanism 600, which performs a "back-blowing + extrusion" combined action on the filter pores to peel off the attached impurities from the filter pores and push them into the housing cavity. Subsequently, the scraping mechanism 700 automatically unlocks after the air blowing is completed and slides down the inner wall of the filter housing under the action of gravity to scrape off the residual dirt. The impact vibration generated when it touches the bottom further loosens the stubborn impurities, achieving the effect of deep cleaning of the filter housing, preventing filter pore blockage and performance degradation. The two mechanisms work together to achieve a highly reliable and thorough self-cleaning function.
