Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for fabric processing. Background Technology

[0002] Fabric dyeing and finishing, also known as dyeing and finishing, is a processing method for fabrics. It is a general term encompassing pretreatment, dyeing, printing, finishing, washing, etc. Textile dyeing and finishing processes consume a large amount of water resources and are among the largest water users. A large amount of dye remains in the industrial wastewater discharged during the dyeing process. If the wastewater is discharged directly, it will cause serious environmental pollution. Therefore, it is necessary to treat the wastewater generated from fabric dyeing. Wastewater treatment uses physical, chemical, and biological methods to purify the wastewater, reduce pollution, and even achieve wastewater recycling and reuse, making full use of water resources.

[0003] Fabric dyeing wastewater contains a large amount of floating matter such as lint, which is not easily dissolved. Therefore, the lint must be filtered out first during wastewater treatment before it is mixed with chemical solutions for further treatment. However, existing wastewater treatment equipment mainly uses filter screens to remove lint and impurities. Over time, the filter screens become clogged with impurities, requiring cleaning and affecting the wastewater treatment efficiency. To address the shortcomings of existing technologies, we propose a wastewater treatment device for fabric processing. Summary of the Invention

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the set movable spring, when the water flow is at the top of the filter screen frame, the pressure of the water flow will push the scraper on one side of the sliding frame, causing the sliding frame to move inside the sliding groove. The scraper will slide on the top of the filter screen frame, pushing and accumulating the impurities on the top of the filter screen frame. Under the action of the inclined surface of the filter screen frame, the impurities will slide into the inside of the sludge box, realizing automatic cleaning and automatic collection.

[0019] 2. Gas is generated by an air pump, which creates bubbles inside the wastewater tank. The stirring motor controls the stirring blades inside the tank to stir the wastewater. When the reagent is added to the tank, the bubbles generated by the air outlet, combined with the stirring action of the stirring blades, reduce the sedimentation of the reagent and make the wastewater more evenly mixed.

[0020] 3. By leveraging the mutual magnetic attraction between the second magnet and the first magnet, when the electric telescopic rod extends or retracts, it controls the sliding block frame to rise and fall within the fixed frame. This allows the second filter screen to rise and fall within the limiting frame via the second magnet, thereby controlling the separate discharge of treated water and impurities, reducing treatment steps, and improving the performance of the wastewater treatment device.

[0021] 4. The primary filtration device is installed to achieve primary filtration of fabric processing wastewater. The treatment agent is added into the tank through the dosing hopper and the dosing pipe.

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1, as Figure 1 - Figure 4 As shown, a wastewater treatment device for fabric processing includes a treatment tank 1, a mixing device 2 at the bottom of the treatment tank 1, a primary filter device 3 fixedly installed at the upper end of the inside of the treatment tank 1, a secondary filter device 4 installed at the lower end of the inside of the treatment tank 1, and a drainage component 5 fixedly installed on one side of the bottom of the treatment tank 1.

[0033] The treatment box 1 includes a box body 11. A box cover 12 is hinged to 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 part of the inside of the box body 11. A dosing hopper 15 is fixedly connected to the upper part of the side of the box body 11. A medicine pipe 16 is fixedly connected to the bottom of the dosing hopper 15. The tail end of the medicine pipe 16 is fixedly connected to the side of the box body 11.

[0034] By installing a chemical tube 16 on one side of the tank 11, the treatment agent can be added into the tank 11 through the dosing hopper 15 and the chemical tube 16, and then mixed by the mixing device 2 to achieve chemical treatment of wastewater.

[0035] like Figure 4 As shown, the primary filtration 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] Scraper 39 is fixedly installed on both sides and the middle of the sliding frame 38. The scraper 39 is slidably installed on the top of the filter screen frame 33. The two sides of the upper end of the filter screen frame 33 are inclined. 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. Sludge boxes 36 are placed on both sides of the filter screen frame 33.

[0037] By setting the sliding groove 32, when the water flow is at the top of the filter screen frame 33, the pressure of the water flow will push the scraper 39 on one side of the sliding frame 38, causing the sliding frame 38 to move inside the sliding groove 32. The scraper 39 will slide on the top of the filter screen frame 33, pushing and accumulating the impurities on the top of the filter screen frame 33, and under the action of the inclined surface of the filter screen frame 33, they will slide into the interior of the sludge box 36.

[0038] The sludge collection box 36 is placed on top of the first filter screen plate 14, and the sludge collection box 36 is placed between the filter screen frame 33 and the fixed 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 undergoes primary filtration through the primary filtration device 3, the wastewater will pass through the top of the filter screen frame 33, 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 right side of the filter screen frame 33 and is filtered by the lint impurities through the right end of the filter screen frame 33. Due to the interception of lint impurities by the filter screen frame 33, when the right end of the filter screen frame 33 is blocked, the water is filtered through the filter screen. The water cannot pass through the top of the filter frame 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 pressured by the water and moves to the right, compressing the movable spring 37. After the water flows through the right side of the filter frame 33, the scraper 39 on the right side of the sliding frame 38 will lose the water pressure. At this time, the movable spring 37 will reset and push the sliding frame 38 to the left. Under the reciprocating motion of the scraper 39 on the right side of the sliding frame 38, the lint and impurities on the top of the filter frame 33 will accumulate and roll into the sludge box 36 through the slope of the filter frame 33, realizing automatic cleaning and automatic collection.

[0040] Example 2, as Figure 1 - Figure 6 As shown, a wastewater treatment device for fabric processing includes a mixing device 2, which is fixedly installed on one side of the lower end of a housing 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. Air outlets 24 are fixedly connected to the four sides of the ventilation box 23. The air outlets 24 are fixedly installed at the bottom of the housing 11.

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

[0042] Gas is generated by air pump 21, which causes bubbles to form inside the wastewater in tank 11. Stirring motor 25 controls stirring blade assembly 26 to stir the wastewater inside tank 11. When the agent is added to the inside of tank 11, the bubbles generated by air outlet 24 and the stirring action of stirring blade assembly 26 reduce the precipitation of the agent and make the wastewater more uniformly mixed.

[0043] Example 3, as shown in the appendix Figure 1- Figure 5 , Figure 7 - Figure 8 As shown, a wastewater treatment device for fabric processing has a fixed frame 18 fixedly connected to both sides of the lower end of the box 11. An electric telescopic rod 19 is fixedly installed on the top of the fixed frame 18. A slider frame 110 is fixedly connected to the bottom of the electric telescopic rod 19. A first magnet 111 is embedded in the inside of the slider frame 110. The slider frame 110 is slidably installed inside the fixed frame 18.

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

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

[0046] By leveraging the mutual attraction between the second magnet 43 and the first magnet 111, when the electric telescopic rod 19 extends or retracts, the slider frame 110 is controlled to rise and fall within the fixed frame 18. This allows the second filter screen 41 to rise and fall within the limiting frame 17 via the second magnet 43, thereby controlling the separate discharge of treated water and impurities.

[0047] Furthermore, a polygonal groove 42 corresponding to the polygonal block 29 is provided in the middle of the polygonal groove 42. When the polygonal block 29 and the stirring blade assembly 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 27 pushes the impurities deposited on the surface of the second filter screen plate 41. When the slag discharge groove 44 reaches one side of the scraper 27, the impurities fall into the interior of the water guide groove 52 through the slag discharge groove 44 and are discharged through the water guide groove 52. This allows the drain pipe 53 to discharge sewage and impurities separately, reducing treatment steps and improving the performance of the wastewater treatment 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 a slope, a drain pipe 53 is fixedly connected to one side of the water guide box 51, a solenoid valve 54 is provided on one side of the drain pipe 53, the top of the water guide groove 52 is connected to the bottom surface of the box 11 and is located on one side of the scraper 27.

[0049] It should be noted that this invention is a wastewater treatment device for fabric processing. In use, the wastewater inlet 13 is connected to the wastewater discharge end. The wastewater passes through the primary filter 3 via the wastewater inlet 13. The tail end of the wastewater inlet 13 is located to the right of the scraper 39 in the middle of the sliding frame 38. At this time, the wastewater passes through the top right side of the filter screen 33 and is filtered for lint and impurities through the right end of the filter screen 33. Due to the interception of lint and impurities by the filter screen 33, when the right end of the filter screen 33 becomes blocked, the water cannot pass through the top of the filter screen 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 water pressure, causing it to flow to the right. Move and compress the movable spring 37. At this time, the wastewater passes through the outer surface of the filter screen 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 filter screen frame 33 on the right side, the scraper 39 on the right side of the sliding frame 38 will lose water pressure. At this time, the movable spring 37 will reset and push the sliding frame 38 to move to the left. The scraper 39 will move back and forth on the top of the filter screen frame 33, causing the lint and impurities on the top of the filter screen frame 33 to accumulate. During the movement of the scraper 39, the lint and impurities will roll down through the inclined surface of the filter screen frame 33 into the interior of the sludge box 36, realizing automatic cleaning and automatic collection. The sludge box 36 can be taken out for cleaning by opening the box cover 12.

[0050] After the wastewater is initially filtered, the treatment agent is added into the tank 11 through the dosing hopper 15 and the dosing pipe 16, and mixed by the mixing device 2. At this time, the stirring motor 25 and the air pump 21 are working. The gas generated by the air pump 21 enters the tank 11 through the air outlet 24 through the connecting air pipe 22, causing bubbles to be generated in the wastewater in the tank 11. The bubbles rise in the wastewater and carry some suspended particles, which plays a stirring role. Under the action of the stirring blade assembly 26 controlled by the stirring motor 25 to stir the wastewater, the mixing effect of wastewater and agent is improved.

[0051] After the wastewater and reagents are mixed, the solenoid valve 54 is activated to filter the wastewater through the second filter screen 41, and it is discharged from the drain pipe 53 through the water guide trough 52. After the treated wastewater is discharged, the electric telescopic rod 19 extends due to the magnetic attraction between the second magnet 43 and the first magnet 111. This causes the slider frame 110 to descend inside the fixed frame 18, allowing the second filter screen 41 to descend inside the limiting frame 17 via the second magnet 43. The second magnet 43 then moves out of the limiting frame 17, and the polygonal groove 42 fits onto the outer surface of the polygonal block 29. At this point... As the second filter plate 41 descends under the influence of gravity, the scraper 27 adheres to the top of the second filter plate 41. During the rotation of the stirring blade assembly 26 controlled by the vent box 23, the polygonal block 29 rotates and controls the rotation of the second filter plate 41 through the polygonal groove 42. At this time, during the rotation of the second filter plate 41, the scraper 27 pushes the precipitated impurities on the surface of the second filter plate 41. When the slag discharge groove 44 reaches one side of the scraper 27, the precipitated impurities fall into the interior of the water guide groove 52 through the slag discharge groove 44 and are discharged through the water guide groove 52.

[0052] After the impurities are cleaned, the stirring motor 25 controls the stirring blade assembly 26 and the lower polygonal block 29 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 27 is located above the slag discharge trough 44, the electric telescopic rod 19 retracts, causing the first magnet 111 inside the slider frame 110 to rise, and the second filter screen plate 41 pushes the scraper 27 to rise together. The second magnet 43 moves into the interior of the limiting frame 17, completing the reset.

[0053] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
