Description

Technical Field

[0001] This invention relates to the field of wastewater recycling technology, specifically to a textile wastewater recycling and reuse system. Background Technology

[0002] The recycling system treats and recycles wastewater generated during textile production to achieve resource recycling and reduce environmental pollution. It includes three stages: pretreatment, advanced treatment, and reuse. Textile wastewater comprises various types of wastewater generated during spinning and weaving, with dyeing and printing wastewater and chemical fiber textile wastewater being the most heavily polluted. Wastewater from textile processing contains various pollutants, thus requiring a wastewater recycling system. Currently, the recycling of textile wastewater requires pretreatment equipment within the system to filter the textile threads carried in the wastewater. The pretreatment equipment uses a screen to filter the textile threads in the wastewater. However, due to the large number of textile threads in the wastewater, the screen is prone to clogging. Therefore, cleaning blades are needed to clean the surface of the screen to ensure normal wastewater flow and filtration. During the cleaning process, the cleaning blades easily entangle and adhere the dispersed textile threads to their surface, causing a buildup of threads that clogs the screen, hindering the smooth flow of wastewater and reducing the equipment's treatment efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a textile wastewater recycling system. By using a first and second arc-shaped blade, which combine to form an S-shaped structure, the system not only cleans the space between the first and second arc-shaped blades and the booster pump, but also removes impurities from their surfaces. This reduces the likelihood of textile threads adsorbing or entangled on the first and second arc-shaped blades, ensuring that the first arc-shaped blades effectively clean the textile threads on the grid, preventing grid blockage, ensuring smooth wastewater flow, improving the equipment's wastewater treatment efficiency, and facilitating wastewater recycling. This addresses the aforementioned shortcomings in the existing technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a textile wastewater recycling system, comprising: a bar screen filter for filtering textile threads from wastewater; an outlet of the bar screen filter connected to a grit and oil separator; an outlet of the grit and oil separator connected to a water collection and equalization tank; an outlet of the water collection and equalization tank connected to a hydrolysis tank; an outlet of the hydrolysis tank connected to an inclined tube sedimentation tank; an inclined tube sedimentation tank connected to a reaction tank and a sludge storage tank; a reaction tank connected to a hydraulic circulation tank and a sludge thickening tank; water discharged from the hydraulic circulation tank being used for water reuse; an outlet of the hydraulic circulation tank connected to an inlet of the sludge thickening tank; and an outlet of the sludge thickening tank connected to the sludge storage tank. The grit and oil separator is mainly used to remove suspended solids and oily substances from the wastewater; the water collection and equalization tank is used to collect, store, and equalize the water quality and quantity of the wastewater to ensure the continuous operation of subsequent treatment equipment; and the hydrolysis tank is used for... The biochemical reaction transforms complex organic matter in wastewater into smaller molecules that are more easily biodegradable, thus effectively improving the biodegradability of the wastewater. The inclined tube sedimentation tank creates a smaller settling path as the water flows through the inclined tubes, allowing suspended particles to settle along the inclined tubes under gravity and eventually settle at the bottom of the tank, shortening the particle settling distance. The reaction tank is a CASS reaction tank, which operates cyclically according to the procedure of "aeration, idle, sedimentation, and drainage," allowing the wastewater to complete carbon and nitrogen removal in the repeated cycles of "aerobic-anoxic" and phosphorus removal in the repeated cycles of "aerobic-anaerobic," resulting in effluent that meets discharge standards. The hydraulic circulation tank draws active sludge from the bottom of the tank into the mixing chamber through high-speed water flow, where it is fully mixed with raw water and coagulant to form flocs. Then, under gravity, the sludge settles and separates, with clear water overflowing from the top and the sludge continuing to participate in the recycling process. The sludge thickening tank is used to reduce the water content of the sludge, and the sludge storage tank is used to store the sediment.

[0005] The bar screen filter includes a wastewater tank and a filter. A lift pump is installed on the wastewater tank and is used to transport wastewater to the filter. A bar screen is installed in the filter and is used to filter textile threads in the wastewater.

[0006] Two sets of filter components are used to clean the textile threads on the surface of the bar screen and to remove the textile threads wrapped around the surface of the filter components, ensuring smooth passage and filtration of wastewater through the bar screen. Each set of filter components includes a rotating column rotatably mounted on the bar screen, a first arc-shaped blade and a second arc-shaped blade respectively mounted on the outside of the rotating column, and an ear plate fixed to the bar screen. The ear plate is equipped with a scraper that cooperates with the first and second arc-shaped blades, and the scraper is used to clean the textile threads on the outside of the first and second arc-shaped blades. The ear plate is provided with a push-out component. The ejector assembly drives the scraper plate to slide and fits it against the outside of the second and first arc-shaped blades. The ear plate is equipped with a rotating assembly that drives the two sets of filter components to rotate clockwise and counterclockwise along the grid. When one of the first arc-shaped blades rotates clockwise, the other rotates counterclockwise, causing the outside of the other first arc-shaped blade to partially contact one of the first arc-shaped blades and clean the weave threads between them. The rotating assembly contains a wave-like component to direct the flow direction of wastewater in front of the second and first arc-shaped blades. The design changes the orientation of the two second arc-shaped blades and the two first arc-shaped blades. The two second arc-shaped blades and the two first arc-shaped blades combine to form an S-shaped structure. As the two second arc-shaped blades rotate clockwise and the two first arc-shaped blades rotate counter-clockwise, the outer parts of one first arc-shaped blade contact the outer parts of the other first arc-shaped blade, cleaning the woven threads between them. Similarly, the two second arc-shaped blades do the same, reducing the adhesion or entanglement of woven threads on the first and second arc-shaped blades. This ensures that the first arc-shaped blades clean the woven threads on the grid, reducing grid blockage. Simultaneously, as the first and second arc-shaped blades rotate along the grid, they change the direction of wastewater flow around the grid, increasing the residence time of wastewater in the treatment system and allowing for more thorough contact with the grid. This helps improve the removal efficiency of pollutants in the wastewater. Furthermore, the change in wastewater flow direction reduces unidirectional impact and wear on the equipment, extending its service life.

[0007] Preferably, the ear plate is further provided with a scraping groove for the scraper plate to slide, and a lifting strip is installed on one side of the scraper plate; and the lifting strip has a wave structure, which can better adapt to the unevenness of the surface of the first and second arc-shaped blades when textile threads are wrapped or adsorbed on the surface of the first and second arc-shaped blades, ensuring that each part can be thoroughly cleaned, facilitating the effective treatment of impurities on the surface of the grid by the first and second arc-shaped blades, further preventing the grid from becoming clogged, and facilitating the recycling and treatment of wastewater.

[0008] Preferably, the ejection assembly includes a connecting seat fixed to one end of the scraper plate and in contact with the first and second arc-shaped blades, a connecting groove formed on the ear plate and communicating with the inside of the scraper groove for the connecting seat to slide, and a stabilizing arc block fixed in the scraper groove. The outer side of the scraper plate has a stabilizing groove for the stabilizing arc block to slide in. A guide block is fixed in the stabilizing groove, and a spring is installed between one side of the stabilizing arc block and the guide block. By setting the ejection assembly, the scraper plate and the first and second arc-shaped blades are arranged opposite to each other, so that the first and second arc-shaped blades and the scraper plate generate a large shearing force, which helps to clean the impurities on the first and second arc-shaped blades and prevent them from re-adhering. At the same time, the connecting seat, the connecting groove, the first and second arc-shaped blades are inclined to each other, which facilitates the contact between the outer side of the first and second arc-shaped blades and the connecting seat and pushes the connecting seat to slide along the connecting groove into the scraper groove. Then, the outer side of the connecting seat passes over the outer side of the first and second arc-shaped blades.

[0009] Preferably, a guide bar is also fixed on the stabilizing arc block, and a limiting groove for the guide bar to slide is provided at the top of the guide block.

[0010] Preferably, a guide block is fixed inside the scraper groove, and a guide groove is provided at the top of the scraper plate for the guide block to slide; and the size of the guide groove is adapted to the guide block, so that the scraper plate slides along the scraper groove, causing the guide groove and the guide block to slide, and is used to restrict the movement position of the scraper plate in the scraper groove, so as to ensure that the scraper plate can move stably.

[0011] Preferably, the rotating assembly includes two mounting boxes fixed to the top of the two ear plates, a rotating column fixed to the top of the rotating column, and a connecting column rotatably installed in the two mounting boxes. A second gear is sleeved on the connecting column. A first gear is fixed to the top of the rotating column and is located in the mounting box and meshes with the second gear. A servo motor is installed on the filter and is used to drive the connecting column to rotate. The number of first gears and second gears is equal to the number of rotating columns, and the first gears and second gears are combined into a set. The two sets of first gears and second gears rotate in different directions, so that the two rotating columns rotate synchronously in both directions on the grid.

[0012] Preferably, the undulating assembly includes two support frames fixed on two mounting boxes, a cam sleeved on a connecting column, and a slide rod slidably connected within the two support frames. The cam is located between the two mounting boxes. Both ends of each support frame are fixed with undulating blocks. Two support rings are fixedly sleeved on each support frame, and the bottom ends of each support ring are fixed with two mating rings that cooperate with the cam. The cam is inclined and located between the two support rings and the mating rings. The ends of the two mating rings that contact the cam are inclined, so that the cam and the two mating rings are inclinedly fitted, causing the slide rod to reciprocate within the two support frames.

[0013] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0014] 1. By setting the first and second arc-shaped blades, and combining the first and second arc-shaped blades to form an S-shaped structure, not only can the first and second arc-shaped blades be cleaned between themselves and the booster pump, but also impurities on the surfaces of the first and second arc-shaped blades can be cleaned. This reduces the possibility of textile threads adsorbing or entangled on the first and second arc-shaped blades, ensuring that the first arc-shaped blades clean the textile threads on the grid, preventing grid blockage, ensuring smooth passage of wastewater, improving the equipment's wastewater treatment effect, and facilitating wastewater recycling.

[0015] 2. By setting the ejection component, the scraper plate can be positioned relative to the first and second arc-shaped blades, resulting in a large shearing force between the first and second arc-shaped blades and the scraper plate. This helps to clean impurities on the first and second arc-shaped blades and prevents them from re-adhering, thus keeping the surfaces of the first and second arc-shaped blades clean.

[0016] 3. By incorporating the lifting strip, the second arc-shaped blade, and the first arc-shaped blade, the corrugated scraper can better adapt to the uneven surfaces of the first and second arc-shaped blades when textile threads are wrapped or adsorbed on them. This ensures thorough cleaning of each part, facilitating effective removal of impurities from the grid surface by the first and second arc-shaped blades, further preventing grid blockage, and facilitating wastewater recycling.

[0017] 4. By setting the oscillating components, the first and second arc-shaped blades can change the flow direction of wastewater around the bar screen when they rotate along the lift pump. This avoids dead water zones or slow-flowing areas caused by a fixed flow direction, helps to evenly distribute and agitate suspended solids, prevents impurities in the wastewater from accumulating in certain parts for a long time, reduces the risk of bar screen blockage, and thus improves the equipment's efficiency in removing impurities from wastewater, facilitating the recycling and treatment of wastewater.

[0018] 5. The rotating component enables the synchronous movement of the first arc blade, the second arc blade, and the slide bar, reducing unnecessary energy transfer, thereby improving the power transmission efficiency of the equipment, enhancing the wastewater agitation effect, improving overall operating efficiency, improving the equipment's wastewater treatment effect, and facilitating wastewater recycling.

[0034] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] This invention provides, for example Figures 1-6The illustrated textile wastewater recycling system includes: a bar screen filter for filtering textile threads from the wastewater; an outlet of the bar screen filter connected to a grit and oil separator; an outlet of the grit and oil separator connected to a water collection and equalization tank; an outlet of the water collection and equalization tank connected to a hydrolysis tank; an outlet of the hydrolysis tank connected to an inclined tube sedimentation tank; the inclined tube sedimentation tank connected to a reaction tank and a sludge storage tank; and the reaction tank connected to a hydraulic circulation tank and a sludge thickening tank. The system discharges wastewater from the hydraulic circulation tank... Water is used for water reuse. The outlet of the hydraulic circulation tank is connected to the inlet of the sludge thickening tank, and the outlet of the sludge thickening tank is connected to the sludge storage tank. The grit and oil separator is mainly used to remove suspended solids and oil from the wastewater. The water collection and equalization tank is used to collect, store, and balance the water quality and quantity of wastewater to ensure the continuous operation of subsequent treatment equipment. The hydrolysis tank is used for biochemical reactions to convert complex organic matter in the wastewater into smaller molecules that are more easily biodegradable, thereby effectively improving the biodegradability of the wastewater. The inclined tube sedimentation tank... As water flows through the inclined tubes, it creates a narrow settling path. Suspended particles sink along the inclined tubes under gravity and eventually settle at the bottom of the tank, shortening the particle settling distance. The reaction tank is a CASS reaction tank, operating cyclically according to the procedure of "aeration, idle, sedimentation, and drainage." This allows the wastewater to complete carbon and nitrogen removal through repeated cycles of "aerobic-anoxic" processes, and phosphorus removal through repeated cycles of "aerobic-anaerobic" processes, resulting in effluent that meets discharge standards. The hydraulic circulation tank uses high-speed water flow to draw activated sludge from the bottom of the tank into the mixing chamber, where it mixes with the raw water. The coagulant is fully mixed to form flocs, which then settle and separate under gravity. Clear water overflows from the top, while the sludge continues to participate in the recycling process. The sludge thickening tank is used to reduce the water content of the sludge, and the sludge storage tank is used to store the sediment. The bar screen filter includes a wastewater tank 1 and a filter 12. A lift pump 11 is installed on the wastewater tank 1, and the lift pump 11 is used to transport wastewater to the filter 12. A bar screen 13 is installed in the filter 12, and the bar screen 13 is used to filter the textile threads in the wastewater.

[0036] Two sets of filter components 2 are used to clean the textile threads on the surface of the bar screen 13 and the textile threads wrapped around the surface of the filter components 2, ensuring that the bar screen 13 can smoothly pass through and filter wastewater. Each set of filter components 2 includes a rotating column 21 rotatably mounted on the bar screen 13, a first arc-shaped blade 22 and a second arc-shaped blade 23 respectively mounted on the outside of the rotating column 21, and an ear plate 24 fixed on the bar screen 13. A scraper 25 that cooperates with the first arc-shaped blade 22 and the second arc-shaped blade 23 is installed in the ear plate 24, and the scraper 25 is used to clean the textile threads on the outside of the first arc-shaped blade 22 and the second arc-shaped blade 23. An ejection component is provided in the ear plate 24. 3. The ejector component 3 is used to drive the scraper plate 25 to slide and to fit the scraper plate 25 with the outside of the second arc-shaped blade 23 and the first arc-shaped blade 22. The ear plate 24 is provided with a rotating component 4, which is used to drive the two sets of filter components 2 to rotate in both directions along the grid 13. When one of the first arc-shaped blades 22 rotates clockwise, the other first arc-shaped blade 22 rotates counterclockwise. Then, the outside of the other first arc-shaped blade 22 comes into contact with part of one of the first arc-shaped blades 22 and cleans the weaving threads between them. The rotating component 4 is provided with a wave component 5, which is used to change the flow direction of wastewater in front of the second arc-shaped blade 23 and the first arc-shaped blade 22.

[0037] The ear plate 24 is also provided with a scraper groove 26 for the scraper plate 25 to slide, and a lifting strip 27 is installed on one side of the scraper plate 25;

[0038] The rotating assembly 4 includes two mounting boxes 41 fixed to the top of the two ear plates 24, a rotating column 46 fixed to the top of the rotating column 21, and a connecting column 43 rotatably installed in the two mounting boxes 41. A second gear 45 is sleeved on the connecting column 43. A first gear 44 is fixed to the top of the rotating column 46. The first gear 44 is located in the mounting box 41 and meshes with the second gear 45. A servo motor 42 is installed on the filter 12 and is used to drive the connecting column 43 to rotate.

[0039] When wastewater is filtered and recycled, the booster pump 11 first absorbs the wastewater inside the wastewater tank 1 and transports the absorbed wastewater to the filter 12. The filter 12's internal grid screen 13 filters the wastewater to ensure further treatment. The servo motor 42 rotates, driving the connecting column 43 to rotate within the mounting box 41. The rotating connecting column 43 then drives the two second gears 45 to rotate. At this time, the two second gears 45 mesh with the two first gears 44, causing the two rotating columns 46 to rotate in both directions within the mounting box 41. Furthermore, the rotation of the two rotating columns 46 drives the two rotating columns 21 to rotate along the grid screen 13. The rotation of the two rotating columns 21 also drives the externally mounted first arc-shaped blades 22 and second arc-shaped blades 23 to rotate, which are used to spin the surface of the grid screen 13. The yarn is cleaned by rotating the first arc-shaped blade 22 and the second arc-shaped blade 23, which alternate with each other and slide along one side of the ear plate 24. Subsequently, the first arc-shaped blade 22 and the second arc-shaped blade 23 are located on one side of the ear plate 24 and are attached to the side of the scraper plate 25 and the lifting bar 27 to process the external yarn of the first arc-shaped blade 22 and the second arc-shaped blade 23. Then, one of the first arc-shaped blades 22 rotates and is attached to the other first arc-shaped blade 22. Similarly, one of the second arc-shaped blades 23 rotates and is attached to the other second arc-shaped blade 23 to clean the externally adsorbed or entangled yarn. This can prevent the grid 13 from becoming blocked, ensure the smooth passage of wastewater, improve the treatment effect of the equipment on wastewater, and facilitate the recycling of wastewater.

[0040] refer to Figures 1-8 As shown, the ejector assembly 3 includes a connecting seat 31 fixed to one end of the scraper plate 25 and in contact with the first arc-shaped blade 22 and the second arc-shaped blade 23; a connecting groove 32 opened on the ear plate 24 and communicating with the inside of the scraper groove 26 for the connecting seat 31 to slide; and a stabilizing arc block 33 fixed in the scraper groove 26. A stabilizing groove 34 is opened on the outside of the scraper plate 25 for the stabilizing arc block 33 to slide. A guide block 35 is fixed in the stabilizing groove 34. A spring 36 is installed between one side of the stabilizing arc block 33 and the guide block 35. A guide strip 37 is also fixed on the stabilizing arc block 33. A limiting groove is opened at the top of the guide block 35 for the guide strip 37 to slide. A guide block 39 is fixed in the scraper groove 26. A guide groove 38 is opened at the top of the scraper plate 25 for the guide block 39 to slide.

[0041] Through the above technical solution:

[0042] When the first arc-shaped blade 22 and the second arc-shaped blade 23 slide along one side of the ear plate 24, the first arc-shaped blade 22 and the second arc-shaped blade 23 first alternately slide along one side of the ear plate 24, and push the connecting seat 31 by contacting and pushing the connecting seat 31 through the inclined surface of one end of the scraper groove 26. Then the connecting seat 31 slides into the connecting groove 32 and pushes the scraper plate 25 to slide along the scraper groove 26. At this time, the scraper plate 25 moves and slides the stabilizing groove 34 opened on one side of it along the outside of the stabilizing arc block 33, and the guide block 35 slides along one side of the stabilizing arc block 33, squeezing the spring 36 between the connecting seat 31 and the guide block 35. Moreover, the movement of the scraper plate 25 drives the guide block 39 to slide along the guide groove 38, thereby As the inclined surface of one end of the connecting seat 31 and the inclined surface of one end of the scraper groove 26 gradually decrease, the connecting seat 31 moves and slides over the inclined surface of one end of the first arc-shaped blade 22. As the spring 36 exerts its own elastic force on one side of the guide block 35, it pushes the guide block 35 to move in the opposite direction along one side of the stabilizing arc block 33. Subsequently, it pushes the scraper plate 25 to move and reset along the scraper groove 26. Then, the outside of the scraper groove 26 moves towards the scraper plate 25 and engages with the inclined surface of one side of the scraper plate 25, which facilitates the relative sliding between the scraper plate 25 and the scraper groove 26. This helps to clean the impurities on the first arc-shaped blade 22 and the second arc-shaped blade 23 and prevents them from re-adhering, which is beneficial to keeping the surfaces of the first arc-shaped blade 22 and the second arc-shaped blade 23 clean.

[0043] refer to Figure 2 and Figure 4 As shown, the wave assembly 5 includes two support frames 52 fixed on two mounting boxes 41, a cam 51 sleeved on a connecting column 43, and a slide rod 53 slidably connected in the two support frames 52. The cam 51 is located between the two mounting boxes 41. Wave blocks 55 are fixed at both ends of the support frame 52. Two support rings 54 are fixedly sleeved on the support frame 52. Two mating rings 56 that cooperate with the cam 51 are fixed at the bottom of the two support rings 54.

[0044] Through the above technical solution:

[0045] When the connecting column 43, the first arc-shaped blade 22, and the second arc-shaped blade 23 rotate, the first arc-shaped blade 22 and the second arc-shaped blade 23 rotate first, which can change the direction of wastewater flow around the grid 13, maintain the flow of wastewater in the filter 12, facilitate the dispersion of textile threads in the wastewater, and drive the cam 51 to rotate through the rotation of the connecting column 43. Then the cam 51 rotates and makes an oblique engagement with one of the mating rings 56. At this time, the rotation of the cam 51 and the mating ring 56 continuously squeeze and push the mating ring 56 to the left. The movement of the mating ring 56 drives the slide rod 53 to move to the left along the two support frames 52, and the slide rod 53... 3. The moving mechanism pushes one of the oscillating blocks 55 to move synchronously. The other end of the cam 51 is engaged with another mating ring 56 at an angle, which pushes the other mating ring 56 to move to the right, causing the slide rod 53 to move to the right along the two support frames 52. This process is repeated, causing the slide rod 53 to move back and forth along the support frame 52. This changes the flow direction of the wastewater around the first arc-shaped blade 22 and the second arc-shaped blade 23, which helps to evenly distribute and agitate suspended solids. This can prevent impurities in the wastewater from accumulating in certain parts for a long time, reduce the risk of clogging the screen 13, and thus improve the equipment's efficiency in removing impurities from wastewater, making it easier to recycle and treat wastewater.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
