It is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. The textile dyeing and finishing process consumes a lot of water resources and is one of the major water users. A large amount of dyes remain in the industrial wastewater discharged during the dyeing process. If the wastewater is discharged directly, it will cause serious pollution to the environment. Therefore, it is necessary to treat the wastewater generated by fabric dyeing.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 - Figure 4 As shown, a fabric processing wastewater treatment device comprises a treatment box 1, a mixing device 2 is arranged at the bottom of the treatment box 1, a primary filtering device 3 is fixedly installed at the upper end of the treatment box 1, a secondary filtering device 4 is arranged at the lower end of the treatment box 1, and a drainage component 5 is fixedly installed at one side of the bottom of the treatment box 1;

[0033] The treatment box 1 includes a box body 11, a box cover 12 is hingedly installed on the top of the box body 11, a sewage inlet 13 is fixedly connected to the top of the box body 11 near the hinge of the box cover 12, a first filter screen 14 is fixedly connected to the upper end of the interior of the box body 11, a medicine hopper 15 is fixedly connected to the upper end of the side of the box body 11, a medicine tube 16 is fixedly connected to the bottom of the medicine hopper 15, and the tail end of the medicine tube 16 is fixedly connected to the side of the box body 11.

[0034] By arranging a medicine pipe 16 on one side of the box body 11, the treatment agent can be put into the interior of the box body 11 through the medicine feeding hopper 15, through the medicine pipe 16, and mixed through the mixing device 2 to achieve chemical treatment of wastewater.

[0035] like Figure 4 As shown, the primary filtering device 3 includes a fixed frame 31, which is fixedly installed on the top of the first filter screen plate 14. Sliding grooves 32 are provided on both sides of the upper end of the fixed frame 31. A filter screen frame 33 is fixedly installed inside the fixed frame 31. Fixed plates 34 are fixedly installed on the left and right sides of the bottom of the filter screen frame 33. Support rods 35 are fixedly installed inside both ends of the fixed plates 34. A movable spring 37 is movably sleeved on the outer surface of one end of the support rod 35. A sliding frame 38 is movably sleeved on the outer surface of the support rod 35. The movable spring 37 is located between the fixed plate 34 and the sliding frame 38.

[0036] Among them, scrapers 39 are fixedly installed on both sides and the middle of the sliding frame 38, and the scraper 39 is slidably installed on the top of the filter frame 33. The two sides of the upper end of the filter frame 33 are inclined surfaces. The scraper 39 in the middle of the sliding frame 38 is located on one side of the tail end of the sewage inlet 13. The sliding frame 38 is slidably installed inside the sliding groove 32, and slag boxes 36 are placed on both sides of the filter frame 33.

[0037] By setting the sliding groove 32, when the water flow on the top of the filter rack 33 is at the top of the filter rack 33, the pressure of the water flow will push the scraper 39 on one side of the sliding rack 38, so that the sliding rack 38 moves inside the sliding groove 32, and the scraper 39 will slide on the top of the filter rack 33, push the impurities on the top of the filter rack 33 to accumulate, and under the action of the inclined surface of the filter rack 33, slide into the inside of the residue box 36.

[0038] The slag box 36 is placed on the top of the first filter screen plate 14 , and the slag box 36 is placed between the filter screen frame 33 and the fixing frame 31 .

[0039] In this embodiment, since the scraper 39 in the middle of the sliding frame 38 is located on one side of the tail end of the sewage inlet 13, when the fabric wastewater passes through the sewage inlet 13 and passes through the primary filtering device 3 for primary filtration, the wastewater will pass through the top of the filter rack 33, which is located on one side of the middle of the sliding frame 38. For example, the tail end of the sewage inlet 13 is located on the right side of the scraper 39 in the middle of the sliding frame 38. At this time, the wastewater passes through the top of the right side of the filter rack 33, and the fluff impurities are filtered through the right end of the filter rack 33. The fluff impurities are intercepted by the filter rack 33. When the right end of the filter rack 33 is blocked, the water in the filter rack is blocked. The top of the frame 33 cannot pass and will flow to the right. At this time, the scraper 39 intercepts the water, and the scraper 39 on the right side of the sliding frame 38 is affected by the water pressure and moves to the right and compresses the movable spring 37. After the water flows through the right side of the filter frame 33 and is filtered, the scraper 39 on the right side of the sliding frame 38 loses the water pressure. At this time, the movable spring 37 is reset and pushes the sliding frame 38 to move to the left. Under the reciprocating motion of the scraper 39 on the right side of the sliding frame 38, the fluff impurities on the top of the filter frame 33 are accumulated and roll down to the inside of the slag box 36 through the inclined surface of the filter frame 33, realizing automatic cleaning and automatic collection.

[0040] Embodiment 2, as Figure 1 - Figure 6 As shown, a wastewater treatment device for fabric processing, the mixing device 2 includes an air pump 21 fixedly installed on one side of the lower end of the box body 11, the output end of the air pump 21 is fixedly connected to a connecting air pipe 22, the tail end of the connecting air pipe 22 is fixedly connected to a ventilation box 23, the four sides of the ventilation box 23 are fixedly connected to air outlet nozzles 24, and the air outlet nozzles 24 are fixedly installed at the bottom of the box body 11.

[0041] like Figure 6 As shown, the mixing device 2 also includes a stirring motor 25, which is fixedly mounted at the bottom of the box body 11, and a stirring knife group 26 is fixedly connected to the output end of the stirring motor 25, and the stirring knife group 26 is rotatably mounted inside the box body 11, and the stirring knife group 26 is rotatably mounted at the bottom of the first filter screen plate 14, and a scraper bar 27 is rotatably mounted on the lower end of the stirring knife group 26, and a sliding block 28 is fixedly mounted on one side of the scraper bar 27, and a polygonal block 29 is fixedly sleeved on the lower end of the stirring knife group 26, and the polygonal block 29 is located between the scraper bar 27 and the stirring motor 25.

[0042] The air pump 21 is used to generate gas to generate bubbles in the wastewater inside the box 11. The stirring motor 25 controls the stirring knife group 26 to stir the wastewater inside the box 11. When the medicine is added into the box 11, the bubbles generated by the air outlet nozzle 24 and the stirring of the stirring knife group 26 are used to reduce the precipitation of the medicine and make the wastewater mixed more evenly.

[0043] Embodiment 3, as attached Figure 1- Figure 5 , Figure 7 - Figure 8 As shown, a wastewater treatment device for fabric processing, both sides of the lower end of the box body 11 are fixedly connected with a fixing frame 18, the top of the fixing frame 18 is fixedly installed with an electric telescopic rod 19, the bottom of the electric telescopic rod 19 is fixedly connected with a slider frame 110, the interior of the slider frame 110 is embedded with a first magnet 111, and the slider frame 110 is slidably installed inside the fixing frame 18.

[0044] like Figure 5 As shown, the four sides of the lower end of the inner wall of the box body 11 are fixedly connected with the limiting frames 17 , the limiting frames 17 on both sides are located on one side of the two fixed frames 18 , and the limiting frames 17 are movably sleeved inside the sliding block 28 .

[0045] like Figure 7 As shown, the secondary filtering device 4 includes a second filter screen plate 41, and the four sides of the second filter screen plate 41 are fixedly connected with second magnets 43, the second magnet 43 is slidably installed inside the limit frame 17, the second magnet 43 is magnetically connected to the first magnet 111, and a slag discharge groove 44 is opened on one side inside the second filter screen plate 41, and a polygonal groove 42 corresponding to the polygonal block 29 is opened in the middle of the polygonal groove 42, and the second filter screen plate 41 is rotatably installed between the bottom of the limit frame 17 and the inner bottom surface of the box body 11.

[0046] Through the mutual magnetic attraction between the second magnet 43 and the first magnet 111, when the electric telescopic rod 19 is extended or retracted, the slider frame 110 is controlled to rise and fall inside the fixed frame 18, so that the second filter screen plate 41 is lifted or lowered inside the limit frame 17 by the second magnet 43, and the lifting or lowering of the second filter screen plate 41 is controlled, thereby realizing the separate discharge of treated water and impurities.

[0047] In addition, a polygonal groove 42 corresponding to the polygonal block 29 is opened in the middle of the polygonal groove 42. When the polygonal block 29 and the stirring knife group 26 rotate, the second filter screen plate 41 will be controlled to rotate. At this time, during the rotation of the second filter screen plate 41, the scraper bar 27 pushes the precipitated impurities on the surface of the second filter screen plate 41. When the slag discharge groove 44 reaches one side of the scraper bar 27, the impurities pass through the slag discharge groove 44 and fall into the inside of the water guide groove 52, and are discharged through the water guide groove 52, so that the drain pipe 53 can discharge sewage and impurities separately, discharge them in a classified manner, reduce the treatment process, and improve the performance of the wastewater device.

[0048] like Figure 8As shown, the drainage assembly 5 includes a water guide box 51, a water guide groove 52 is provided on the top of the water guide box 51, the bottom of the water guide groove 52 is an inclined surface, one side of the water guide box 51 is fixedly connected to a drainage pipe 53, one side of the drainage pipe 53 is provided with a solenoid valve 54, the top of the water guide groove 52 is connected to the bottom surface of the box body 11, and is located on one side of the scraper strip 27.

[0049] It should be noted that the present invention is a wastewater treatment device for fabric processing. When in use, the sewage inlet 13 is connected to the discharge end of the wastewater, and the wastewater passes through the primary filtering device 3 through the sewage inlet 13. The tail end of the sewage inlet 13 is located on the right side of the scraper 39 in the middle of the sliding frame 38. At this time, the wastewater passes through the top of the right side of the filter rack 33, and the fluff impurities are filtered through the right end of the filter rack 33, and the fluff impurities are intercepted by the filter rack 33. When the right end of the filter rack 33 is blocked, the water cannot pass through the top of the filter rack 33 and will flow to the right. At this time, the scraper 39 intercepts the water, and the scraper 39 on the right side of the sliding frame 38 is subjected to the pressure of the water and will flow to the right. The movable spring 37 moves and compresses the movable spring 37. At this time, the waste water passes through the outer surface of the filter frame 33 on the left side of the scraper 39 in the middle of the sliding frame 38. After the water flows through the unblocked end of the right side of the filter frame 33 and is filtered, the scraper 39 on the right side of the sliding frame 38 will lose the water pressure. At this time, the movable spring 37 resets and pushes the sliding frame 38 to move to the left. The scraper 39 reciprocates left and right on the top of the filter frame 33, so that the fluff impurities on the top of the filter frame 33 accumulate, and in the process of the scraper 39 moving, through the inclined surface of the filter frame 33, roll down to the inside of the slag box 36, realizing automatic cleaning and automatic collection. The slag box 36 can be taken out and cleaned by opening the box cover 12.

[0050] After the wastewater is initially filtered, the treatment agent is put into the interior of the box 11 through the drug feeding hopper 15 and the drug pipe 16, and mixed through the mixing device 2. At this time, the stirring motor 25 and the air pump 21 are working, and the gas generated by the air pump 21 enters the interior of the box 11 from the air outlet nozzle 24 through the connecting air pipe 22, so that bubbles are generated in the wastewater of the box 11. The bubbles rise in the wastewater and carry some suspended particles to rise, which has a stirring effect. Under the action of the stirring motor 25 controlling the stirring blade group 26 to stir in the wastewater, the mixing effect of the wastewater and the agent is improved;

[0051] After the wastewater is mixed with the reagent, the solenoid valve 54 is activated to filter the wastewater through the second filter screen 41 and discharge it from the drain pipe 53 through the water guide groove 52. When the treated wastewater is discharged, the second magnet 43 and the first magnet 111 are attracted to each other. When the electric telescopic rod 19 is extended, the slider frame 110 is controlled to descend inside the fixing frame 18, so that the second filter screen 41 descends inside the limiting frame 17 through the second magnet 43. The second magnet 43 moves out of the limiting frame 17, and the polygonal groove 42 is sleeved on the outer surface of the polygonal block 29. At this time, The scraper bar 27 is affected by gravity. As the second filter screen plate 41 descends, it is attached to the top of the second filter screen plate 41. During the process of the ventilation box 23 controlling the stirring knife group 26 to rotate, the polygonal block 29 rotates and controls the second filter screen plate 41 to rotate through the polygonal groove 42. At this time, during the rotation of the second filter screen plate 41, the scraper bar 27 pushes the precipitated impurities on the surface of the second filter screen plate 41. When the slag discharge groove 44 reaches one side of the scraper bar 27, the precipitated impurities pass through the slag discharge groove 44 and fall into the inside of the water guide groove 52, and are discharged through the water guide groove 52.

[0052] After the impurities are cleaned, the stirring motor 25 controls the stirring knife group 26 and the polygonal block 29 at the lower end to rotate, so that when the second magnet 43 stops rotating, it is magnetically attracted to the first magnet 111. At this time, the scraper bar 27 is located above the slag discharge trough 44, and the electric telescopic rod 19 contracts, so that the first magnet 111 inside the slider frame 110 rises, and the second filter screen plate 41 pushes the scraper bar 27 to rise together, and the second magnet 43 moves into the interior of the limit frame 17 to complete the reset.

[0053] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
