[0001] This invention belongs to the technical field of wastewater treatment, specifically relating to a prefabricated wastewater treatment device for non-woven fabric dyeing wastewater treatment. Background Technology

[0002] The wastewater generated by the nonwoven fabric dyeing industry is complex, containing a large amount of organic dyes, fiber debris and chemical auxiliaries. Traditional wastewater treatment equipment often uses fixed filter screens or single filter cartridges, which are difficult to deal with impurities of different particle sizes, and are inconvenient to clean and replace, affecting continuous operation.

[0003] To address the aforementioned issues, this patent proposes an integrated wastewater treatment device capable of multi-stage collaborative processing, continuous forced filtration, and easy maintenance, thereby resolving the technical problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated wastewater treatment device for non-woven fabric dyeing wastewater treatment, in order to solve the problem mentioned in the background art that traditional wastewater treatment devices using fixed filter screens or single filter cartridges are difficult to deal with impurities of different particle sizes.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated wastewater treatment device for non-woven fabric dyeing wastewater treatment, comprising a wastewater tank, a clear water tank being provided outside the wastewater tank, and a multi-port pipe being connected to the upper side of the wastewater tank and the clear water tank at their respective ends. The wastewater tank is connected to multiple tee pipes through multiple ports of the multi-port pipes, and multiple symmetrically arranged side connecting pipes are symmetrically connected through the other two ports of the tee pipes. A strong filter assembly is connected between two symmetrical side connecting pipes, and the multiple strong filter assemblies are connected to the clear water tank through multiple ports of another multi-port pipe.

[0006] Preferably, the high-pressure filtration assembly includes a clear water tank, which is disposed between the two side connecting pipes, and the outside of the clear water tank is connected to a connecting pipe head, and is connected to the clear water pool through the connecting pipe head and a multi-port pipe.

[0007] Preferably, a filter pipe connected to the side connecting pipe is provided at both ends of the clean water tank, and a flow control plate is provided between the two filter pipes and the two side connecting pipes.

[0008] Preferably, the filter tube has multiple flow control holes at the end near the clean water tank and inside the flow control plate, and each of the multiple flow control holes has a limit ring at the end away from the clean water tank.

[0009] Preferably, the limiting ring is connected to a plurality of limiting slide rods that pass through the control flow hole on the outer side of the end near the clean water tank, and a sealing plate located on the side of the control flow hole near the clean water tank is connected to the plurality of limiting slide rods.

[0010] Preferably, the clean water tank is provided with a linkage frame inside, and the upper and lower ends of the linkage frame are respectively attached to the inner walls of the upper and lower ends of the clean water tank and are slidably connected to the clean water tank.

[0011] Preferably, both ends of the linkage frame near the two ports of the clean water tank are connected to piston rods that penetrate inside the filter tube, and the ends of the two piston rods away from the linkage frame are connected to filter pistons.

[0012] Preferably, the filter piston is slidably connected inside the filter tube, and a drive motor is provided outside the clean water tank, with the output shaft of the drive motor passing through the inside of the clean water tank.

[0013] Preferably, the output shaft of the drive motor is externally fitted with a connecting seat fixed by bolts, and a connecting rod is radially connected to the outside of the connecting seat.

[0014] Preferably, the connecting rod is externally connected to an eccentric rod parallel to the output shaft of the drive motor, and the eccentric rod passes through the inside of the linkage frame and is slidably connected inside the linkage frame.

[0015] Compared with the prior art, the present invention provides a prefabricated wastewater treatment device for non-woven fabric dyeing wastewater treatment, which has the following beneficial effects:

[0016] 1. The wastewater tank of this invention is provided with a decolorization chamber, a sedimentation chamber and a clear liquid chamber in sequence to continuously treat wastewater. The decolorization chamber introduces air through an aeration pipe frame and introduces biological liquid through a biological liquid pipe head. Aerobic microorganisms decompose organic matter to reduce COD. The sedimentation chamber uses a stepped deceleration plate to slow down the water flow and promote the sedimentation of impurities. The clear liquid chamber collects the upper clear liquid and transfers it to a strong filter component for forced filtration. The combination of biodegradation and physical sedimentation improves the efficiency of pollutant removal.

[0017] 2. This invention uses a strong filtration assembly to form a one-way valve mechanism through a flow control plate, a sealing plate, and a limiting slide rod. When the filter piston slides, negative and positive pressures are used to control the opening and closing of the flow control orifice, ensuring that the wastewater and clear liquid can only flow into the filter pipe in one direction from the side connecting pipe, and the filtered clear water is discharged into the clear water tank in one direction, preventing liquid backflow and ensuring the continuity and stability of the filtration process. At the same time, the reciprocating motion of the piston achieves forced suction and squeezing, improving filtration efficiency.

[0018] 3. The filter piston of this invention consists of a piston seat and multiple detachable filter units. Each filter unit consists of a sealing frame and a filter element. The filter elements of different materials can be arranged in stages according to the pore size, which can accurately intercept impurities of different particle sizes. The detachable filter elements can be quickly installed and replaced, which improves the filtration accuracy and water output stability, and reduces maintenance costs.

[0019] 4. The drive motor inside the water tank of this invention drives the linkage frame to slide laterally back and forth through the eccentric rod, thereby causing the filter pistons on both sides to alternately perform suction and squeezing actions, ensuring that the two filter cylinders work alternately and achieve uninterrupted forced filtration. At the same time, the sliding cooperation between the linkage frame and the inner wall of the water tank restricts the position of the linkage frame and avoids it from flipping and getting stuck.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This invention provides, for example Figures 1-9 The wastewater treatment equipment shown is a prefabricated wastewater treatment device for non-woven fabric dyeing. It includes a wastewater tank 1 and a clear water tank 2 located outside the wastewater tank 1. Both the wastewater tank 1 and the clear water tank 2 are connected to a multi-port pipe 3 at their upper sides. Multiple tee pipes 4 are connected to the wastewater tank 1 through multiple ports of the multi-port pipes 3, and multiple symmetrically arranged side connecting pipes 5 are symmetrically connected to the other two ports of the tee pipes 4. Each pair of symmetrical side connecting pipes 5 is connected to a high-pressure filter assembly, and the multiple high-pressure filter assemblies are connected to the clear water through multiple ports of another multi-port pipe 3. Pool 2 is connected. The end of sewage pool 1 furthest from multi-port pipe 3 is connected to an inlet pipe and a biological liquid pipe. A decolorization chamber 24 is located inside sewage pool 1 near the inlet pipe, and a clear liquid chamber 26 is located inside sewage pool 1 near multi-port pipe 3. A sedimentation chamber 25 is located between the decolorization chamber 24 and the clear liquid chamber 26. The sedimentation chamber 25 contains multiple speed-reducing plates with stepped upper ends. The bottom of the sedimentation chamber 25 is connected to a sewage discharge pipe outside sewage pool 1, which is sealed with a pipe cap. The bottom of the decolorization chamber 24 is... An aeration pipe frame 27 is provided, and an air guide pipe head is connected to the outside of the sewage tank 1. A filter screen 28 is installed on the upper end of the decolorization chamber 24 near the water inlet pipe head, and an inlet opening connected to the water inlet pipe head is opened on the outer wall of the filter screen 28. During the sewage treatment process, the sewage tank 1 is connected to the non-woven fabric dyeing sewage pipe through the water inlet pipe head and to the biological liquid pipe through the biological liquid pipe head. At the same time, the aeration pipe frame 27 is connected to the aeration pipe through the air guide pipe head. The sewage from the non-woven fabric dyeing process is carried out through the water inlet pipe. The wastewater is introduced into the decolorization chamber 24 of the wastewater tank 1 and then into the filter screen 28 through the inlet for preliminary filtration, removing confining debris from the wastewater. At the same time, biological liquid, such as aerobic microbial agents, for decomposing pollutants is introduced through the biological liquid pipeline, and air is introduced through the aeration pipe frame 27. This allows the aerobic microorganisms in the biological liquid to use the oxygen in the introduced air to adsorb, oxidize, and decompose organic matter. The introduced air also stirs and mixes the wastewater and prevents the sedimentation of pollutants, thereby gradually reducing the COD of the wastewater.

[0032] Furthermore, the wastewater treated with aerobic microbial agents enters the sedimentation chamber 25, and the water flow velocity is reduced by the stepped deceleration plate inside the sedimentation chamber 25, so that the pollutants in the wastewater settle inside the sedimentation chamber 25. The settled pollutants can be discharged through the sewage pipe, while the clear liquid in the upper layer inside the sedimentation chamber 25 flows into the clear liquid chamber 26 for collection.

[0033] Furthermore, the clear liquid inside the clear liquid chamber 26 is drawn into the three-way pipe 4 through the multi-way pipe 3, and then introduced into the strong filter assembly for forced filtration through the side connecting pipe 5. Finally, it is introduced into the clear water tank 2 for collection through the multi-way pipe 3 on the other side. The bottom outer end of the clear water tank 2 is connected to a drain pipe head, which is connected to the drainage pipe to discharge the treated clear water inside the clear water tank 2.

[0034] like Figures 3-6 As shown, the high-pressure filtration assembly includes a clear water tank 6, which is located between two side connecting pipes 5. A connecting pipe head 7 is connected to the outside of the clear water tank 6, and it is connected to the clear water pool 2 via the connecting pipe head 7 and a multi-port pipe 3. Filter pipes 8 connected to the side connecting pipes 5 are located at both ends of the clear water tank 6. A flow control plate 9 is located between the two filter pipes 8 and the two side connecting pipes 5. Multiple flow control holes 10 are provided at the end of the filter pipes 8 near the clear water tank 6 and inside the flow control plate 9. Limiting rings 11 are provided at the ends of the multiple flow control holes 10 away from the clear water tank 6. Multiple limiting sliding rods 12, penetrating inside the flow control holes 10, are connected to the outer side of the limiting rings 11 near the clear water tank 6. A sealing plate 13 located on the side of the flow control hole 10 near the clear water tank 6 is connected via the multiple limiting sliding rods 12. A linkage frame 14 is provided inside the clear water tank 6, and the linkage frame 14 is positioned vertically and horizontally. The ends are respectively attached to the inner walls of the upper and lower ends of the clear water tank 6 and are slidably connected to the clear water tank 6. The two ends of the linkage frame 14 near the two ports of the clear water tank 6 are connected to piston rods 15 that pass through the inside of the filter tube 8. The ends of the two piston rods 15 away from the linkage frame 14 are connected to filter pistons 16. The filter pistons 16 are slidably connected inside the filter tube 8. During the process of strong filtration of the clear liquid inside the clear liquid chamber 26, the filter tube 8 and the flow control plate 9 can form a forced suction filter cylinder. The filter cylinder can be connected to the side connecting pipe 5 and the clear water tank 6 through multiple flow control holes 10 at both ends. In addition, the limiting ring 11 can be connected to the sealing plate 13 through multiple limiting slide rods 12 to form a sealing piston. It can seal and open the flow control holes 10 according to the direction of water flow, so that the sewage can flow unidirectionally from the side connecting pipe 5 to the clear water tank 6 inside the filter cylinder.

[0035] Furthermore, during the sliding process of the filter piston 16 inside the filter tube 8, when the filter piston 16 slides towards the side closer to the clear water tank 6, the space in the filter tube 8 on the side of the filter piston 16 away from the clear water tank 6 increases, generating negative pressure. This negative pressure draws the sealing disc 13 on the side away from the clear water tank 6 out from the control flow hole 10, connecting the side connecting pipe 5 and the filter tube 8, and drawing in the sewage and clear liquid inside the side connecting pipe 5. At the same time, the filtered water in the filter tube 8 on the side of the filter piston 16 closer to the clear water tank 6 is squeezed, increasing the water pressure. This water pressure then forces the sealing disc 13 on the side closer to the clear water tank 6 out from the control flow hole 10, connecting the clear water tank 6 and the filter tube 8, and guiding the filtered water inside the filter tube 8 into the clear water tank 6. Finally, it is guided into the clear water pool 2 for collection through the connecting pipe head 7 and the multi-port pipe 3.

[0036] At this time, the filter cartridge is in a connected state. By sliding the filter piston 16 inside the filter tube 8, one end draws in the sewage and clear liquid inside the side connecting pipe 5, and the other end discharges the filtered clear water.

[0037] Furthermore, when the filter piston 16 slides away from the clear water tank 6, the wastewater and clear liquid on the side of the filter pipe 8 away from the clear water tank 6 are squeezed and generate high pressure. This high pressure forces the sealing disc 13 on the side away from the clear water tank 6 into the control flow hole 10, sealing the space between the side connecting pipe 5 and the filter pipe 8 and preventing the wastewater and clear liquid drawn into the filter pipe 8 from flowing back into the side connecting pipe 5. At the same time, the space on the side of the filter pipe 8 near the clear water tank 6 increases, generating negative pressure. This negative pressure forces the sealing disc 13 on the side near the clear water tank 6 into the control flow hole 10, sealing the space between the clear water tank 6 and the filter pipe 8 and preventing the filtered water introduced into the clear water tank 6 from flowing back into the filter pipe 8.

[0038] At this time, the filter cartridge is in a closed state. The sewage and clean liquid drawn into the filter tube 8 are forced to pass through the filter piston 16 by the sliding of the filter piston 16. The filtered clean water is collected in the inner cavity of the filter tube 8 on the side of the filter piston 16 near the clean water tank 6, and is introduced into the clean water tank 6 when the filter piston 16 slides in a certain direction.

[0039] Thus, the filter pistons 16 located on both sides of the clear water tank 6 are connected as a whole through the linkage frame 14 in the middle and the piston rod 15, and are slidably connected to the inside of the filter cylinders on both sides, so that the filter cylinders on both sides of the clear water tank 6 can alternately suck in the sewage liquid, perform strong filtration, and discharge the filtered clear water. This alternating filtration ensures the continuity of filtration and improves filtration efficiency in conjunction with forced filtration.

[0040] Among them, such as Figure 9As shown, the filter piston 16 consists of a piston seat 21 and multiple filter units. Each filter unit consists of a sealing frame 22 and a filter element 23. The piston seat 21 is threadedly connected to the piston rod 15 and further fixed by bolts. A rubber sealing ring is provided between the sealing frame 22 and the inner wall of the filter tube 8, and is threadedly connected to the piston seat 21 and the adjacent sealing frame 22. When the filter tube is in a closed state and the filter piston 16 slides inside the filter tube 8, the wastewater clear liquid can pass through multiple filter elements 23 for multiple filtrations. The multiple filter elements 23 are made of various different materials, allowing the multiple filter elements 23 to intercept the impurities inside the wastewater clear liquid step by step according to the particle size of the impurities inside the wastewater clear liquid through the design of the size of the internal gap of different materials. This can improve the filtration efficiency and the stability of the effluent, ensuring filtration efficiency.

[0041] In addition, multiple filter elements 23 made of different materials can accurately filter impurities of different natures, and can simultaneously intercept impurities of various forms, thereby improving the filtration effect. Furthermore, multiple filter elements 23 can be quickly installed and removed through the sealing frame 22, making subsequent maintenance and replacement more convenient.

[0042] like Figures 4-8 As shown, a drive motor 17 is installed outside the clean water tank 6, and the output shaft of the drive motor 17 passes through the inside of the clean water tank 6. A connecting seat 18, which is fixed by bolts, is sleeved on the outside of the output shaft of the drive motor 17, and a connecting rod 19 is radially connected to the outside of the connecting seat 18. An eccentric rod 20, which is parallel to the output shaft of the drive motor 17, is connected to the outside of the connecting rod 19. The eccentric rod 20 passes through the inside of the linkage frame 14 and is slidably connected inside the linkage frame 14. During the process of strong filtration of wastewater and clean liquid, the drive motor 17 is electrically connected to an external power source through a wiring harness. After the drive motor 17 is started, the drive motor 17 drives the connecting seat 18, the connecting rod 19 and the eccentric rod 20 to rotate through the output shaft, and drives the linkage frame 14 to slide inside the clean water tank 6 through the eccentric rod 20.

[0043] Furthermore, since the eccentric rod 20 rotates eccentrically around the output shaft of the drive motor 17, and the outer walls of the upper and lower ends of the linkage frame 14 are attached to and slide against the inner walls of the upper and lower ends of the clean water tank 6, the eccentric rod 20 will drive the linkage frame 14 to slide laterally repeatedly inside the clean water tank 6. Under the restriction of the inner wall of the clean water tank 6, it will not flip over. At the same time, the limit formed between the clean water tank 6 and the linkage frame 14 will not cause significant wear, allowing the linkage frame 14 to drive the filter pistons 16 on both sides to repeatedly draw inside the filter cylinder through the piston rod 15, thereby achieving continuous forced filtration of wastewater and clean liquid.

[0044] In addition, rubber sealing gaskets are provided at the connection points of the above-mentioned water inlet pipe head, biological liquid pipe head, aeration pipe head, drain pipe head, multi-way pipe 3, tee pipe 4, side connecting pipe 5, clear water tank 6, connecting pipe head 7 and flow control plate 9.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
