Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to an integrated wastewater treatment device for chemical fiber and textile industries. Background Technology

[0002] The chemical fiber and textile industry generates a large amount of wastewater containing fiber impurities, suspended particulate matter, and organic pollutants during the production process. This type of wastewater has a complex composition and high pollutant concentration. Direct discharge would cause serious harm to the ecological environment. Therefore, it must be strictly treated before it can be discharged in compliance with standards.

[0003] Chinese Patent Publication No. CN118594077A discloses a fiber interception and filtration device for textile wastewater. This device uses an inclined conveying pipe, with the textile wastewater tank positioned higher than the intermediate transfer box. The textile wastewater inside the conveying pipe creates an impact force, causing the connecting plate to rotate around a fixed axis. This causes the fiber collection box to rotate around the inner side of a circular hole, scraping off fibers adsorbed on the outer side of the fine filter plate, preventing fiber blockage and reduced drainage efficiency. The fibers adsorbed on the outer side of the fine filter plate are self-cleaning, requiring no external force. However, in this device, the intermediate transfer box is disc-shaped, and the fine filter plate is arc-shaped. After entering the intermediate transfer box, the wastewater must flow through the circular hole to the fine filter plate. The water flow easily forms eddies inside the intermediate transfer box, causing some wastewater to stagnate and reducing drainage efficiency. Furthermore, in some existing wastewater treatment devices, the right-angled inner wall of the conveying pipe during interception leads to uneven water flow velocity distribution, making it easy for impurities to accumulate at the bottom and corners of the pipe. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: an integrated treatment device for chemical fiber textile wastewater, comprising: a pre-filtration component, wherein the pre-filtration component is configured as a bent pipe structure with an inverted triangular cross section, a support frame is fixedly installed at the bottom of the pre-filtration component, and an inlet plate and an outlet component are fixedly installed on the outer surface of the pre-filtration component respectively, and both the inlet plate and the outlet component are configured as V-shaped structures adapted to the pre-filtration component. The top of the pre-filtration component is fixedly installed with a dispensing component, which is used for uniform spraying of wastewater treatment agents. The pre-filtration component is connected to the treatment tank through an outlet component. The pre-filtration assembly includes a V-shaped conduit. A splash guard is fixedly installed on the top of the V-shaped conduit. Protective frames are fixedly installed on both sides of the outer surface of the V-shaped conduit. A buffer pad is fixedly installed between the protective frames and the V-shaped conduit. Fixed seats are fixedly installed on both sides of the inner wall of the V-shaped conduit. An extension rod is fixedly installed inside the fixed seat. A positioning rod is fixedly installed on the surface of the extension rod. A hook and auger are rotatably installed on the surface of the positioning rod. Chemical fiber textile wastewater flows into the V-shaped conduit through the inlet plate. Its curved, inverted triangular cross-section structure guides the water flow in a specific direction, causing fibers and flocculent impurities to initially gather at the bottom due to gravity. The curved, inverted triangular cross-section design not only achieves directional flow of wastewater but also utilizes gravity to promote impurity aggregation, improving the interception efficiency of the subsequent hook and auger. The adaptable connection between the two ends of the V-shaped conduit and the inlet plate and outlet assembly ensures the continuity of wastewater treatment and eliminates dead zones.

[0005] Preferably, the V-shaped conduit is configured with a curved structure, and its two ends are fixedly connected to the inlet plate and the outlet assembly, respectively. The protective frame is fixedly installed on both sides of the top of the support frame, and the buffer pad is made of rubber and is attached to the surface of the V-shaped conduit. The protective frames on both sides of the conduit are fixed to the top of the support frame and are in close contact with the rubber buffer pad between the conduit and the conduit. The impact vibration generated when wastewater flows in the V-shaped conduit can be absorbed by the rubber buffer pad, avoiding rigid collision between the V-shaped conduit and the protective frame, reducing structural wear of the V-shaped conduit, ensuring the structural stability of the assembly, and preventing the conduit from deforming or loosening due to long-term impact.

[0006] Preferably, the hook and auger component includes a sleeve, with rotating rings fixedly installed at both ends of the sleeve. Outer expansion plates are fixedly installed on the outer surface of the sleeve, and each outer expansion plate has hook grooves on its surface. When water flows through the inside of the guide tube, it drives the hook and auger component to rotate. The hook and auger component is rotatably mounted on a positioning rod via the sleeve and rotating rings. The positioning rod is supported and fixed by a fixed seat to ensure structural stability. The flexible outer expansion plates are circumferentially distributed and rotate adaptively with the water flow. The hook grooves on their surface can efficiently hook and entangle fibrous impurities in the wastewater. The rotating outer expansion plates achieve dynamic interception, solving the problem of easy clogging of traditional filter screens.

[0007] Preferably, the sleeve is rotatably mounted on the outer surface of the positioning rod via a swivel ring, and the outer expansion plates are circumferentially distributed on the surface of the sleeve, and the outer expansion plates are made of a flexible material. Wastewater that has passed through the hook and twist member to intercept fibrous impurities flows along the V-shaped conduit to the outlet assembly, entering the subsequent treatment stage. The intercepted impurities can be cleaned by disassembling the hook and twist member.

[0008] Preferably, the dosing assembly includes a mounting plate, an injection hopper fixedly mounted on the top of the mounting plate, and a spray pipe fixedly mounted on the bottom of the injection hopper. The spray pipe has spray holes on its surface, and stabilizing rods are fixedly mounted on both sides of its outer surface. The operator pours the wastewater treatment agent into the injection hopper, which is fixed to the top of the mounting plate, guiding the agent to flow into the spray pipe below. After entering the spray pipe, the agent is dispersed through the evenly distributed spray holes on its surface and enters the V-shaped conduit of the pre-filtration assembly in a dispersed spray manner. This adapts to the overall structure of the pre-filtration assembly, ensuring that the agent evenly covers the wastewater flowing through the conduit, avoiding problems of excessively high or low local concentrations of the agent, ensuring thorough mixing of the agent and wastewater, and improving the reaction efficiency of subsequent treatment.

[0009] Preferably, the mounting plate is fixedly installed on top of the splash guard, and the two ends of the stabilizing rod abut against the inner wall of the V-shaped guide tube. The spray pipe is supported between the opposite sides of the V-shaped guide tube by the stabilizing rod. The spray pipe is supported between the inner walls of the V-shaped guide tube by the stabilizing rods on both sides, and the two ends of the stabilizing rod abut against the inner wall of the guide tube, ensuring that the spray pipe remains stable under the impact of water flow and ensuring that the dispensing component does not shift or shake during the operation of the device.

[0010] Preferably, the outlet component includes a guide V-plate, on the surface of which a filter hook is fixedly installed, and the bottom of the filter hook has a filter hole. After the wastewater completes preliminary filtration and mixes with the reagent through the V-shaped conduit of the pre-filtration component, it flows into the guide V-plate. The guide V-plate guides the wastewater to flow towards the outlet of the device and concentrates the wastewater in the area of ​​the filter hook. Both the guide V-plate and the positioning baffle plate adopt a V-shaped structure, which is fully compatible with the V-shaped conduit of the pre-filtration component, and can guide the wastewater to flow in a specific direction, avoiding water flow turbulence or dead corners, and ensuring the smooth flow of wastewater.

[0011] Preferably, the guide V-plate is fixedly connected to the V-shaped conduit, and the filter hook is installed on the side of the outer surface of the V-shaped conduit via the guide V-plate. The wastewater, after secondary filtration, passes through the filter holes and is stably discharged to the subsequent treatment tank via the guide V-plate, completing the final stage of the pretreatment process.

[0012] Preferably, the filter hook includes a positioning baffle plate. A barrier rubber sheet is fixedly installed on the outer surface of the positioning baffle plate. A raised pad is fixedly installed on the surface of the barrier rubber sheet. A fixing ring is fixedly installed at the bottom of the barrier rubber sheet. A barb is fixedly installed on the surface of the fixing ring. The positioning baffle plate of the filter hook has a V-shaped structure and fits against the side of the guide V-plate. The filter holes on its side are the main flow channels for wastewater. Before passing through the filter holes, the wastewater first comes into contact with the barrier rubber sheet above the positioning baffle plate. The barrier rubber sheet can block fine suspended impurities that have not been intercepted by the pre-filtration component. At the same time, the barb on the fixing ring at the bottom of the positioning baffle plate will hook and catch residual fibrous impurities in the wastewater, achieving deep interception of impurities, further reducing the pollutant load of the subsequent treatment tank, and improving the overall treatment efficiency.

[0013] Preferably, the positioning folding plate is configured with a V-shaped structure, the filter hole is opened on the side of the positioning folding plate that fits against the flow guiding V plate, and the barrier rubber sheet is mounted above the filter hole.

[0014] This invention provides an integrated treatment device for chemical fiber textile wastewater. It has the following beneficial effects: (I) This integrated wastewater treatment device for chemical fiber textiles allows wastewater to flow into a V-shaped conduit via an inlet plate. The curved, inverted triangular cross-section guides the water flow in a specific direction, causing fibers and flocculent impurities to initially accumulate at the bottom due to gravity. The curved, inverted triangular cross-section design not only directs the wastewater flow but also utilizes gravity to promote impurity accumulation, improving the interception efficiency of subsequent hooks and tangles. The adaptable connections at both ends of the V-shaped conduit with the inlet plate and outlet components ensure continuous wastewater treatment without any dead zones.

[0015] (II) The integrated treatment device for chemical fiber and textile wastewater is fixed to the top of the support frame by the protective frames on both sides of the conduit. The rubber buffer pad between the conduit and the conduit is tightly fitted. The impact vibration generated when the wastewater flows in the V-shaped conduit can be absorbed by the rubber buffer pad, avoiding rigid collision between the V-shaped conduit and the protective frame, reducing structural wear of the V-shaped conduit, ensuring the stability of the component structure, and preventing the conduit from deforming or loosening due to long-term impact.

[0016] (III) This integrated wastewater treatment device for chemical fiber textiles utilizes a mechanism where water flow through the conduit drives the hook-and-loop mechanism to rotate. The hook-and-loop mechanism is mounted on a positioning rod via a sleeve and a rotating ring. The positioning rod is supported and fixed by a fixed base to ensure structural stability. The flexible outer expansion plates are circumferentially distributed and rotate adaptively with the water flow. The hook grooves on their surface can efficiently hook and entangle fiber impurities in the wastewater. The rotating outer expansion plates achieve dynamic interception, solving the problem of easy clogging in traditional filters.

[0017] (iv) In this integrated wastewater treatment device for chemical fiber textiles, the operator pours the wastewater treatment agent into the injection hopper, which is fixed to the top of the mounting plate, guiding the agent to flow into the spray pipe below. After entering the spray pipe, the agent is sprayed into the V-shaped conduit of the pre-filtration component through evenly distributed nozzles on its surface. This adapts to the overall structure of the pre-filtration component, ensuring that the agent evenly covers the wastewater flowing through the conduit, avoiding problems of excessively high or low local concentrations of the agent, ensuring thorough mixing of the agent and wastewater, and improving the reaction efficiency of subsequent treatment.

[0018] (V) This integrated wastewater treatment device for chemical fiber textiles utilizes a V-shaped positioning baffle plate for the filter hook, which fits against the side of the guide V-plate. The filter holes on its side serve as the main flow channel for wastewater. Before passing through the filter holes, the wastewater first contacts the barrier rubber sheet above the positioning baffle plate. This barrier rubber sheet blocks fine suspended impurities that have not been intercepted by the pre-filtration components. Simultaneously, the barbs on the fixing ring at the bottom of the positioning baffle plate further hook and catch any remaining fibrous impurities in the wastewater, achieving deep interception of impurities, further reducing the pollutant load on subsequent treatment tanks, and improving overall treatment efficiency.

The pre-filtration component 3 is connected to the treatment tank through the outlet component 2. The pre-filtration component 3 includes a V-shaped conduit 36. A splash guard 31 is fixedly installed on the top of the V-shaped conduit 36. Protective frames 32 are fixedly installed on both sides of the outer surface of the V-shaped conduit 36. A buffer pad 37 is fixedly installed between the protective frame 32 and the V-shaped conduit 36. Fixed seats 33 are fixedly installed on both sides of the inner wall of the V-shaped conduit 36. An extension rod 35 is fixedly installed inside the fixed seat 33. A positioning rod 38 is fixedly installed on the surface of the extension rod 35. A hook and tether 34 is rotatably installed on the surface of the positioning rod 38. Chemical fiber textile wastewater flows into the V-shaped conduit 36 ​​through the inlet plate 5. Its curved inverted triangular cross-section structure guides the water flow in a specific direction, causing fibers and flocculent impurities to initially gather at the bottom due to gravity. The curved inverted triangular cross-section design not only achieves directional flow of wastewater, but also uses gravity to promote the aggregation of impurities, thereby improving the interception efficiency of the subsequent hook and auger 34. The V-shaped conduit 36 ​​is adapted to the inlet plate 5 and the outlet component 2 at both ends, ensuring the continuity of wastewater treatment and eliminating dead corners.

[0023] The V-shaped conduit 36 ​​is configured with a curved structure. Both ends of the V-shaped conduit 36 ​​are fixedly connected to the inlet plate 5 and the outlet component 2, respectively. The protective frame 32 is fixedly installed on both sides of the top of the support frame 1. The buffer pad 37 is made of rubber and is fitted against the surface of the V-shaped conduit 36. The protective frames 32 on both sides of the conduit are fixed to the top of the support frame 1 and are tightly fitted with the rubber buffer pad 37 between the conduit and the conduit. The impact vibration generated when wastewater flows inside the V-shaped conduit 36 ​​can be absorbed by the rubber buffer pad 37, avoiding rigid collisions between the V-shaped conduit 36 ​​and the protective frame 32, reducing structural wear of the V-shaped conduit 36, ensuring the stability of the component structure, and preventing deformation or loosening of the conduit due to long-term impact.

[0024] The hook and entanglement component 34 includes a sleeve 341, with rotating rings 343 fixedly installed at both ends of the sleeve 341. Outer expansion plates 342 are fixedly installed on the outer surface of the sleeve 341, and hook grooves 344 are formed on the surface of each outer expansion plate 342. When water flows through the inside of the guide tube, it drives the hook and entanglement component 34 to rotate. The hook and entanglement component 34 is rotatably mounted on a positioning rod 38 via the sleeve 341 and rotating rings 343. The positioning rod 38 is supported and fixed by a fixing seat 33 to ensure structural stability. The flexible outer expansion plates 342 are circumferentially distributed and rotate adaptively with the water flow. The hook grooves 344 on their surface can efficiently hook and entangle fibrous impurities in the wastewater. The rotating outer expansion plates 342 achieve dynamic interception, solving the problem of easy clogging of traditional filter screens.

[0025] The sleeve 341 is rotatably mounted on the outer surface of the positioning rod 38 via the swivel ring 343. The outer expansion piece 342 is circumferentially distributed on the surface of the sleeve 341 and is made of a flexible material. Wastewater that has passed through the hook and twist member 34 to intercept fibrous impurities flows along the V-shaped conduit 36 ​​to the outlet assembly 2 and enters the subsequent processing stage. The intercepted impurities can be cleaned by disassembling the hook and twist member 34.

[0026] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 2 , Figure 4 , Figure 7 and Figure 8As shown, the dosing component 4 includes a mounting plate 42. An injection hopper 41 is fixedly mounted on the top of the mounting plate 42, and a spray pipe 43 is fixedly mounted on the bottom of the injection hopper 41. Spray holes 45 are formed on the surface of the spray pipe 43, and stabilizing rods 44 are fixedly mounted on both sides of the outer surface of the spray pipe 43. The operator pours the wastewater treatment agent into the injection hopper 41, which is fixed to the top of the mounting plate 42, guiding the agent to flow into the spray pipe 43 below. After entering the spray pipe 43, the agent is dispersed and sprayed into the V-shaped conduit 36 ​​of the pre-filtration component 3 through the evenly distributed spray holes 45 on its surface. This adapts to the overall structure of the pre-filtration component 3, ensuring that the agent evenly covers the wastewater flowing through the conduit, avoiding problems of excessively high or low local concentrations of the agent, ensuring thorough mixing of the agent and wastewater, and improving the reaction efficiency of subsequent treatment.

[0027] The mounting plate 42 is fixedly installed on top of the splash guard 31. The two ends of the stabilizing rod 44 abut against the inner wall of the V-shaped guide tube 36. The spray pipe 43 is supported between the opposite sides of the V-shaped guide tube 36 via the stabilizing rod 44. The spray pipe 43 is supported between the inner walls of the V-shaped guide tube 36 via the stabilizing rods 44 on both sides, with the two ends of the stabilizing rods 44 abutting against the inner wall of the guide tube, ensuring that the spray pipe 43 remains stable under the impact of water flow and ensuring that the dispensing component 4 does not shift or shake during device operation.

[0028] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figure 3 , Figure 5 and Figure 6 As shown, the outlet component 2 includes a guide V-plate 22, on the surface of which a filter hook 21 is fixedly installed. The bottom of the filter hook 21 has a filter hole 23. After the wastewater undergoes preliminary filtration and mixes with the reagent through the V-shaped conduit 36 ​​of the pre-filtration component 3, it flows into the guide V-plate 22. The guide V-plate 22 guides the wastewater towards the outlet of the device and concentrates it in the area of ​​the filter hook 21. Both the guide V-plate 22 and the positioning baffle 211 adopt a V-shaped structure, which is perfectly compatible with the V-shaped conduit 36 ​​of the pre-filtration component 3. This allows for directional flow of wastewater, avoiding turbulent flow or dead zones, and ensuring smooth wastewater flow.

[0029] The guide V-plate 22 is fixedly connected to the V-shaped conduit 36, and the filter hook 21 is set on the side of the outer surface of the V-shaped conduit 36 ​​through the guide V-plate 22. The wastewater after secondary filtration passes through the filter hole 23 and is stably discharged to the subsequent treatment tank through the guide V-plate 22, completing the final stage of the pretreatment phase.

[0030] The filter hook 21 includes a positioning baffle 211. A barrier rubber sheet 212 is fixedly installed on the outer surface of the positioning baffle 211. A raised pad 214 is fixedly installed on the surface of the barrier rubber sheet 212. A fixing ring 215 is fixedly installed at the bottom of the barrier rubber sheet 212. A barb 213 is fixedly installed on the surface of the fixing ring 215. The positioning baffle 211 of the filter hook 21 has a V-shaped structure and fits against the side of the guide V-plate 22. The filter holes 23 on its side are the main flow channels for wastewater. Before the wastewater passes through the filter holes 23, it will first come into contact with the barrier rubber sheet 212 above the positioning baffle 211. The barrier rubber sheet 212 can block fine suspended impurities that have not been intercepted by the pre-filtration component 3. At the same time, the barb 213 on the fixing ring 215 at the bottom of the positioning baffle 211 will hook and catch the fibrous impurities remaining in the wastewater, achieving deep interception of impurities, further reducing the pollutant load of the subsequent treatment tank, and improving the overall treatment efficiency.

[0031] The positioning folding plate 211 is configured with a V-shaped structure, the filter hole 23 is opened on the side of the positioning folding plate 211 that is attached to the flow guiding V plate 22, and the barrier rubber sheet 212 is mounted above the filter hole 23.

[0032] In use, chemical fiber textile wastewater flows into the V-shaped conduit 36 ​​through the inlet plate 5. Its curved inverted triangular cross-section structure guides the water flow in a specific direction, causing fibers and flocculent impurities to initially gather at the bottom due to gravity. The curved inverted triangular cross-section design not only achieves directional flow of wastewater but also utilizes gravity to promote the aggregation of impurities, improving the interception efficiency of the subsequent hook and tangling component 34. The two ends of the V-shaped conduit 36 ​​are adapted to connect with the inlet plate 5 and the outlet component 2, ensuring the continuity of wastewater treatment and eliminating dead zones.

[0033] The protective frames 32 on both sides of the conduit are fixed to the top of the support frame 1 and are tightly fitted with the rubber buffer pads 37 between the conduit and the conduit. The impact vibration generated by the wastewater flowing in the V-shaped conduit 36 ​​can be absorbed by the rubber buffer pads 37, avoiding rigid collision between the V-shaped conduit 36 ​​and the protective frames 32, reducing structural wear of the V-shaped conduit 36, ensuring the stability of the component structure, and preventing the conduit from deforming or loosening due to long-term impact.

[0034] As water flows through the conduit, it drives the hook and loop component 34 to rotate. The hook and loop component 34 is rotatably mounted on the positioning rod 38 via the sleeve 341 and the rotating ring 343. The positioning rod 38 is supported and fixed by the fixing seat 33 to ensure structural stability. The flexible material outward expansion piece 342 is circumferentially distributed and rotates adaptively with the water flow. The hook grooves 344 on its surface can efficiently hook and entangle fibrous impurities in the wastewater. The rotating outward expansion piece 342 achieves dynamic interception, solving the problem of easy clogging of traditional filter screens.

[0035] The operator pours the wastewater treatment agent into the injection hopper 41, which is fixed to the top of the mounting plate 42, guiding the agent to flow into the spray pipe 43 below. After entering the spray pipe 43, the agent is sprayed in a dispersed manner through the evenly distributed nozzles 45 on its surface into the V-shaped conduit 36 ​​of the pre-filter assembly 3. This adapts to the overall structure of the pre-filter assembly 3, ensuring that the agent evenly covers the wastewater flowing through the conduit, avoiding problems of excessively high or low local concentrations of the agent, ensuring thorough mixing of the agent and wastewater, and improving the reaction efficiency of subsequent treatment.

[0036] The spray pipe 43 is mounted between the inner walls of the V-shaped guide tube 36 by the stabilizing rods 44 on both sides. The two ends of the stabilizing rods 44 abut against the inner wall of the guide tube to ensure that the spray pipe 43 remains stable under the impact of water flow and to ensure that the dispensing component 4 does not shift or shake during the operation of the device.

[0037] Wastewater that has passed through the hook and twist member 34 to intercept fiber impurities flows along the V-shaped conduit 36 ​​to the outlet component 2 and enters the subsequent treatment stage. The intercepted impurities can be cleaned by disassembling the hook and twist member 34.

[0038] After the wastewater undergoes preliminary filtration and is mixed with the reagent through the V-shaped conduit 36 ​​of the pre-filtration component 3, it flows into the guide V-plate 22. The guide V-plate 22 guides the wastewater to flow towards the outlet of the device and concentrates the wastewater in the area of ​​the filter hook 21. The guide V-plate 22 and the positioning baffle 211 both adopt a V-shaped structure, which is fully compatible with the V-shaped conduit 36 ​​of the pre-filtration component 3. This can guide the wastewater to flow in a directional manner, avoid water flow turbulence or dead corners, and ensure the smooth flow of wastewater.

[0039] The positioning baffle 211 of the filter hook 21 has a V-shaped structure and fits against the side of the guide V-plate 22. The filter holes 23 on its side are the main flow channels for wastewater. Before passing through the filter holes 23, the wastewater will first come into contact with the barrier rubber sheet 212 above the positioning baffle 211. The barrier rubber sheet 212 can block fine suspended impurities that have not been intercepted by the pre-filtration component 3. At the same time, the barbs 213 on the fixing ring 215 at the bottom of the positioning baffle 211 will hook and catch the fibrous impurities remaining in the wastewater, achieving deep interception of impurities, further reducing the pollutant load of the subsequent treatment tank, and improving the overall treatment efficiency.

[0040] The wastewater, after secondary filtration, passes through filter holes 23 and is stably discharged to the subsequent treatment tank via guide plate 22, completing the final stage of the pretreatment process.
