Description

Technical Field

[0001] The invention relates to the technical field of wastewater recycling, and in particular to a textile wastewater recycling system. Background Art

[0002] The recycling and reuse system treats and recycles the wastewater generated in the textile production process to achieve the recycling of resources and reduce environmental pollution. It includes three stages: pretreatment, deep treatment and reuse. Textile wastewater is various wastewater generated in the spinning and weaving process, among which the most polluted are printing and dyeing wastewater and chemical fiber textile wastewater. The wastewater generated by textile processing contains various pollutants. Therefore, a wastewater recycling and reuse system is needed. At present, when recycling textile wastewater, it is necessary to use the pretreatment equipment in the wastewater recycling and reuse system to ensure that the textile threads carried in the textile wastewater are filtered. The pretreatment equipment uses a grid net to filter the textile threads in the wastewater. Since there are many textile threads in the wastewater, it is easy to cause blockage to the grid net. Therefore, it is necessary to clean the textile threads on the surface of the grid net with cleaning blades to ensure the normal circulation and filtration of the wastewater. Since the cleaning blades are in the process of cleaning the textile threads, it is easy to entangle the scattered textile threads with each other and adsorb them on the surface of the cleaning blades, so that more textile threads are accumulated and entangled on the surface of the cleaning blades, which is easy to cause blockage to the grid net, affecting the smooth passage of wastewater and reducing the treatment effect of the equipment on wastewater. Summary of the invention

[0003] The purpose of the present invention is to provide a textile wastewater recycling and reuse system. Through the arrangement of a first curved blade and a second curved blade, and the first curved blade and the second curved blade are combined to form an S-shaped structure, not only can the first curved blade and the second curved blade be cleaned from the lifting pump, but also the impurities on the surface of the first curved blade and the second curved blade can be cleaned, reducing the adsorption or entanglement of the textile thread on the first curved blade and the second curved blade, ensuring that the first curved blade cleans the textile thread on the grille net, preventing the grille net from being blocked, ensuring the smooth passage of wastewater, and improving the treatment effect of the equipment on wastewater, facilitating the recycling and treatment of wastewater, so as to solve the above-mentioned deficiencies in the technology.

The inclined tube sedimentation tank allows water to form a smaller sedimentation path when flowing in the inclined tube. Suspended particles sink along the inclined tube under the action of gravity and eventually settle at the bottom of the pool, shortening the particle sedimentation distance. The reaction tank is a CASS reaction tank, and it operates in a program cycle of "aeration, idleness, sedimentation, and drainage", so that the sewage can complete carbon removal and nitrogen removal in the repeated "aerobic-anoxic" cycle, and complete phosphorus removal in the repeated "aerobic-anaerobic" cycle, and the effluent can meet the discharge standards. The hydraulic circulation tank uses high-speed water flow to suck the active sludge at the bottom of the pool into the mixing chamber, fully mix it with raw water and coagulant to form flocs, and then precipitate and separate under the action of gravity. Clean water overflows from the upper layer, and the sludge continues to participate in the circulation treatment. The sludge concentration tank is used to reduce the water content of the sludge, and the sludge storage tank is used to store the sediment.

Similarly, the two second arc blades are also the same, reducing the adsorption or entanglement of the textile threads on the first arc blade and the second arc blade, ensuring that the first arc blade cleans the textile threads on the grille net, and reducing the blockage of the grille net. At the same time, when the first arc blade and the second arc blade rotate along the grille net, the direction of the wastewater flow around the grille net can be changed, which can increase the residence time of the wastewater in the treatment system, make it more fully contact with the grille net, and help improve the removal efficiency of pollutants in the wastewater.

At this time, the two second gears 45 rotate and mesh with the two first gears 44, driving the two rotating columns 46 to rotate forward and reversely in the installation box 41, and the two rotating columns 46 rotate to drive the two rotating columns 21 to rotate along the grid net 13, and the two rotating columns 21 rotate to drive the first arc blade 22 and the second arc blade 23 installed on the outside to rotate, which is used to spin the surface of the grid net 13. The weaving thread is cleaned, and as the first arc blade 22 and the second arc blade 23 rotate, they are used to alternate with each other and slide along one side of the ear plate 24. Then, the first arc blade 22 and the second arc blade 23 are located on one side of the ear plate 24 and fit with the scraping plate 25 and the lifting bar 27 to process the external textile thread of the first arc blade 22 and the second arc blade 23.

[0041] Through the above technical solution:

[0042] When the first arc blade 22 and the second arc blade 23 slide along one side of the ear plate 24, first the first arc blade 22 and the second arc blade 23 slide along one side of the ear plate 24 alternately, and fit between the inclined surface at one end of the scraping groove 26 and the inclined surface at one end of the connecting seat 31 and push the connecting seat 31, and then the connecting seat 31 slides into the connecting groove 32 and pushes the scraping plate 25 to slide along the scraping groove 26. At this time, the scraping plate 25 moves to slide the stabilizing groove 34 opened on one side 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, and the scraping plate 25 moves to drive the guide block 39 to slide along the guide groove 38, so that The inclined surface at one end of the connecting seat 31 and the inclined surface at one end of the scraping groove 26 are continuously reduced, and then the connecting seat 31 moves and slides over the inclined surface at one end of the first arc-shaped blade 22. As the elastic force of the spring 36 itself gives a thrust to one side of the guide block 35, the guide block 35 is pushed to move in the opposite direction along the side of the stabilizing arc block 33, and then the scraping plate 25 is pushed to move along the scraping groove 26 to reset. Then the outside of the scraping groove 26 moves toward the side of the scraping plate 25 and cooperates with the inclined surface of the side of the scraping plate 25, so as to maintain relative sliding between the scraping plate 25 and the scraping groove 26, which helps to clean the impurities on the first arc-shaped blade 22 and the second arc-shaped blade 23 and prevent them from re-adhering, which is beneficial to keep the surface of the first arc-shaped blade 22 and the second arc-shaped blade 23 clean.

Two support rings 54 are fixedly sleeved on the support frames 52, and two matching rings 56 matching with the convex plate 51 are fixed at the bottom ends 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, first the first arc-shaped blade 22 and the second arc-shaped blade 23 rotate, which can change the direction of the wastewater flow around the grille 13, maintain the fluidity of the wastewater in the filter 12, and facilitate the dispersion of the textile threads in the wastewater. The convex disc 51 is driven to rotate by the rotation of the connecting column 43, and then the convex disc 51 rotates to match the slope between one end of the convex disc 51 and one of the matching rings 56. At this time, the convex disc 51 rotates and continuously squeezes and pushes one of the matching rings 56 to move to the left, and the movement of the matching ring 56 drives the slide bar 53 to move to the left along the two support frames 52, and the slide bar 5 The movement of the undulating block 55 is driven to move synchronously, and the other end of the convex plate 51 is rotated to match the slope of the other matching ring 56, so as to drive the other matching ring 56 to move rightward, and drive the slide bar 53 to move rightward along the two support frames 52, and reciprocate in sequence, so that the slide bar 53 reciprocates left and right along the support frame 52, and then changes the flow direction of the wastewater around the first arc blade 22 and the second arc blade 23, which is helpful for uniform distribution and stirring of suspended matter, and can prevent impurities in the wastewater from being deposited for a long time in certain parts, reduce the risk of clogging of the grid net 13, thereby improving the removal efficiency of the equipment for wastewater impurities, and facilitating the recycling of wastewater.
