Description

Technical Field

[0001] The present invention belongs to the technical field of wastewater treatment, and more specifically, particularly relates to a wastewater treatment device for clothing washing. Background Art

[0002] With the development of the clothing manufacturing industry, the discharge of clothing washing wastewater is increasing day by day. This type of wastewater contains a large amount of fibers. If directly discharged without treatment, it will cause serious pollution to water bodies, harm aquatic organisms, and may also affect the surrounding ecological environment through soil infiltration and other means. Therefore, wastewater treatment equipment is needed.

[0003] Currently, the existing device (such as publication number: CN112960809A) discloses a sewage treatment device for dyed denim clothing. This device can stir the sewage during sewage treatment through a stirring component, can discharge the sewage with more sediment at the bottom of the reaction barrel through a switch component, can pour reaction drugs into the reaction barrel and stir them together while stirring through a drug component, thereby converting the sewage into clean water, can discharge the water in the reaction barrel through a floating component, can filter out the floating impurities in the sewage through an impurity removal component, can further purify the water through a filtering component, and can collect the treated clean water through a collection component; However, during the implementation of the above technical solution, it is found that there are at least the following technical problems: During the use of clothing, due to wear, some fibers are likely to fall off during the cleaning process. When this device is in use, it cannot perform pre-treatment of fiber salvage on the conveyed wastewater. Since fibers have strong adsorption properties, they will adsorb sewage treatment agents, thereby reducing the effective drug concentration and easily affecting the wastewater treatment effect.

[0010] Preferably, the dosing structure further includes a first one-way valve, a second one-way valve, an aeration device, a feed pipe, and a medicine delivery pipe.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by setting up a fiber collection structure, in the pretreatment tank, the high-speed rotating synchronous belt, with its certain linear speed and surface area, drives part of the wastewater to rotate together, generating a strong water flow disturbance. The fibers doped in the wastewater, under the entrainment of the water flow and the centrifugal force generated by the rotation of the synchronous belt, the scraping comb plates fixedly installed on the surface filtering structure of the synchronous belt will collect the fibers, avoiding the fibers remaining inside the wastewater, which may cause fiber-like and wool-like balls to wrap the flocculant molecules, reducing the effective drug concentration and affecting the subsequent wastewater treatment effect, thus improving the practicability. In the present invention, when the synchronous belt drives the filtering structure to rotate, whenever the filtering structure rotates to the top wheel area, the top strip on the filtering structure will actively hit the top wheel, and through the flexible connection of the spring, the top strip drives the scraping comb plate to move downward inside the slide rail bracket, so that the fibers remaining on the scraping comb plate are scraped off, avoiding the fibers remaining on the scraping comb plate and further reducing the fiber residue in the wastewater. In the present invention, by setting up the first baffle, the second baffle and the scraping plate, after the fibers on the filtering structure are scraped off, the first baffle and the second baffle can play a guiding role for the fibers to ensure that the fibers can smoothly enter the extrusion cavity. At the same time, when the extrusion block squeezes the fibers in the extrusion cavity, some of the fibers scraped off from the filtering structure may fall on the upper surface of the extrusion block. During the reset process of the extrusion block, the scraping plate can scrape these fibers into the extrusion cavity, preventing the fibers from accumulating on the extrusion block. The scraping plate can ensure that the fibers can be continuously collected and processed, avoiding the influence of fiber residue on the fiber treatment effect of the device, and making the whole fiber collection and treatment process smoother and more efficient. In the present invention, when the output shaft of the motor rotates, the motor will drive the rotating rod to rotate through the conveyor belt at this time, so that the disc and the eccentric shaft on the disc rotate, making the slide bar drive the extrusion block to reciprocate between the extrusion cavity and the side shell, and generating a radial force on the rotating shaft through the connecting rod to pull the slide bar to complete the crank reciprocating motion, thereby squeezing the fibers in the extrusion cavity, extruding the liquid absorbed by the fibers, and flowing into the pretreatment tank through the circulation pipe, so that the liquid with the pollutant concentration contained in the fibers is centrally treated, improving the treatment convenience. In the present invention, by installing the aeration device on an inclined bracket, different-direction forces are generated on the wastewater when the bubbles rise, forming a more complex water flow movement. This water flow movement helps to better drive the fibers in the wastewater to the working area of the filtering structure, facilitating the salvage treatment by the synchronous belt and improving the removal effect of the fibers in the wastewater. In the present invention, by setting the first one-way valve and the second one-way valve, when the slide bar drives the extrusion block and the piston gasket to move reciprocally, the piston gasket will complete the effects of inhaling and compressing air inside the side shell through the first one-way valve and the second one-way valve, enabling the air to be squeezed into the aeration device through the first one-way valve and the feed pipe. When the bubbles generated by the aeration device are discharged upward, the fibers float to the working area of the filtering structure through the air flotation effect, allowing more fibers inside the wastewater to be salvaged and processed by the synchronous belt, further improving the treatment effect. At the same time, there is no need to externally connect an air pump, improving energy conservation. And by setting a medicine delivery pipe on the circumferential surface of the feed pipe, when the staff treats the wastewater, they can convey the prepared wastewater treatment liquid into the aeration device through the medicine delivery pipe and the feed pipe by an external liquid medicine conveyor. Also, when the piston gasket returns to its original position, the conveyance of the compressed air can further discharge the residual treatment liquid inside the feed pipe.

Detailed implementation manners

[0015] The following further describes in detail the implementation manners of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0016] Please refer to Figure 1 - Figure 10 , the present invention provides a wastewater treatment device for clothing washing, including a pretreatment tank 11, and fixed plates 12 are symmetrically and fixedly installed at the upper end of the pretreatment tank 11; A fiber collection structure is provided between the inside of the pretreatment tank 11 and the fixed plates 12; The fiber collection structure includes a plurality of driving rollers 13 and a synchronous belt 14. The plurality of driving rollers 13 are respectively rotatably installed between the inside of the pretreatment tank 11 and the fixed plates 12. The synchronous belt 14 is sleeved outside the plurality of driving rollers 13. Motors 15 are fixedly installed on the surfaces of both fixed plates 12, and the output shafts of both motors 15 are fixedly connected to the driving rollers 13 on the fixed plates 12. A plurality of filtering structures 16 are provided on the surface of the synchronous belt 14; By setting the fiber collection structure, in the pretreatment tank 11, the high-speed rotating synchronous belt 14 drives part of the wastewater to rotate together with its certain linear speed and surface area, generating a strong water flow disturbance. The fibers doped in the wastewater, under the entrainment of the water flow and the centrifugal force generated by the rotation of the synchronous belt 14, the scraping comb plate 52 of the filtering structure 16 fixedly installed on the surface of the synchronous belt 14 will collect the fibers, preventing the fibers from remaining in the wastewater, which may cause fiber-like and wool ball-like substances to wrap the flocculant molecules, reducing the effective drug concentration and affecting the subsequent wastewater treatment effect, thereby improving the practicability.

[0017] Top wheels 17 are fixedly installed on the opposite sides of both fixed plates 12, and a medicine dosing structure is symmetrically and fixedly installed inside the pretreatment tank 11. The medicine dosing structure includes an inclined bracket 42; By installing the aeration device 43 on the inclined bracket 42, different-direction forces are generated on the wastewater when the bubbles rise, forming a more complex water flow motion. This water flow motion helps to better drive the fibers in the wastewater to the working area of the filtering structure 16, facilitating the salvage treatment by the synchronous belt 14 and improving the removal effect of the fibers in the wastewater.

[0018] Each filtering structure 16 includes a slide rail bracket 51, a scraping comb plate 52 and a pair of springs 54. Each slide rail bracket 51 is fixedly connected to the synchronous belt 14. The scraping comb plate 52 is slidably installed inside the slide rail bracket 51. Each pair of springs 54 is fixedly connected to the lower end of the scraping comb plate 52 and the surface of the synchronous belt 14. Symmetrically fixed to the upper end of the bracket of each scraping comb plate 52 are top bars 53, and each top bar 53 is adapted to the top wheel 17. When the synchronous belt 14 drives the filtering structure 16 to rotate, whenever the filtering structure 16 rotates to the area of the top wheel 17, the top bar 53 on the filtering structure 16 will actively impact the top wheel 17. Through the flexible connection of the spring 54, the top bar 53 drives the scraping comb plate 52 to move downward inside the slide rail bracket 51, so that the fibers remaining on the scraping comb plate 52 are scraped off, preventing the fibers from remaining on the scraping comb plate 52 and further reducing the fiber residue in the wastewater.

[0019] A first baffle 18 is fixedly installed between the two fixing plates 12, a second baffle 19 is fixedly installed between the two fixing plates 12, the second baffle 19 is located on the same side of the pretreatment tank 11, and a scraping plate 21 is fixedly installed on the side of the fixing plates 12 away from the second baffle 19. By providing the first baffle 18, the second baffle 19 and the scraping plate 21, after the fibers on the filtering structure 16 are scraped off, the first baffle 18 and the second baffle 19 can guide the fibers to ensure that the fibers can smoothly enter the inside of the extrusion cavity 23. At the same time, when the extrusion block 29 extrudes the fibers in the extrusion cavity 23, some of the fibers scraped off from the filtering structure 16 may fall on the upper surface of the extrusion block 29. During the reset process of the extrusion block 29, the scraping plate 21 can scrape these fibers into the inside of the extrusion cavity 23, preventing the fibers from accumulating on the extrusion block 29. The scraping plate 21 can ensure that the fibers can be continuously collected and processed, avoiding the influence of fiber residue on the treatment effect of the device on the fibers and making the entire fiber collection and treatment process smoother and more efficient.

[0020] A lower housing 22 is fixedly installed on the side wall of the pretreatment tank 11. The lower housing 22 is fixedly connected to the fixing plate 12. An extrusion cavity 23 is provided inside the lower housing 22. A through groove 24 is provided through the bottom of the extrusion cavity 23, and a circulation pipe 25 is provided inside the through groove 24. A filter screen 26 is provided at the upper end of the circulation pipe 25. By setting up the circulation pipe 25, the water source after fiber extrusion can be recycled. By setting up the filter screen 26, fibers can be prevented from entering the subsequent wastewater treatment process again, improving reliability. At the same time, the circulation pipe 25 installed by threading can be disassembled to handle the fibers on the filter screen 26.

[0021] On the side wall of the lower housing 22, a side housing 27 is fixedly installed. Inside the side housing 27, sliding grooves 28 are symmetrically formed through. An extrusion block 29 is slidably installed between the extrusion cavity 23 and the inside of the side housing 27. The scraping plate 21 is attached to the upper surface of the extrusion block 29. A piston seal gasket 31 is fixedly installed on the side wall of the extrusion block 29. Slide bars 32 are symmetrically and fixedly installed on the side wall of the extrusion block 29. Both of the two slide bars 32 are slidably installed inside the sliding grooves 28. One end of each of the two slide bars 32 extends to the outside of the side housing 27. Rotating shafts 33 are rotatably installed on the surfaces of both of the two slide bars 32. Rotating rods 34 are rotatably installed on the surface of the lower housing 22 symmetrically. Transmission belts 35 are sleeved between the two rotating rods 34 and the output shaft of the motor 15. Discs 36 are fixedly installed on the circumferential surfaces of both of the two rotating rods 34. Eccentric shafts 37 are fixedly installed on the surfaces of both of the two discs 36. A connecting rod 38 is rotatably installed between the two eccentric shafts 37 and the rotating shafts 33. The motor 15 can drive the discs 36 and the eccentric shafts 37 to rotate through the transmission belt 35, generating a radial force on the rotating shafts 33 to make the extrusion block 29 and the slide bars 32 complete a crank reciprocating motion. When the output shaft of the motor 15 rotates, at this time, the motor 15 will drive the rotating rod 34 to rotate through the transmission belt 35, making the discs 36 and the eccentric shafts 37 on the discs 36 rotate, making the slide bars 32 drive the extrusion block 29 to reciprocate between the extrusion cavity 23 and the side housing 27 and generating a radial force on the rotating shafts 33 through the connecting rod 38, pulling the slide bars 32 to complete a crank reciprocating motion, thereby squeezing the fibers inside the extrusion cavity 23, squeezing out the liquid absorbed by the fibers, and flowing through the circulation pipe 25 into the pretreatment tank 11, enabling centralized treatment of the liquid with the pollutant concentration contained in the fibers and improving the convenience of treatment.

[0022] The chemical dosing structure further includes first one-way valves 39, second one-way valves 41, aeration devices 43, feed pipes 44 and chemical medicine pipes 55. The two first one-way valves 39 are both arranged on the surface of the side housing 27. The second one-way valves 41 are arranged on the side wall of the side housing 27. The two aeration devices 43 are both arranged at the ends of the inclined brackets 42. The two feed pipes 44 are fixedly connected between the aeration devices 43 and the first one-way valves 39. The two chemical medicine pipes 55 are fixedly connected to the circumferential surfaces of the feed pipes 44. A cover plate 45 is fixedly installed between the two fixing plates 12. By setting the first one-way valve 39 and the second one-way valve 41, when the slide bar 32 drives the extrusion block 29 and the piston gasket 31 to reciprocate, the piston gasket 31 will complete the effects of inhaling and compressing air inside the side housing 27 through the first one-way valve 39 and the second one-way valve 41, so that the air is squeezed into the aeration device 43 through the first one-way valve 39 and the feed pipe 44. When the bubbles generated by the aeration device 43 are discharged upward, the fibers float to the working area of the filtering structure 16 through the air flotation effect, enabling more fibers in the wastewater to be fished by the synchronous belt 14 for treatment, further improving the treatment effect. At the same time, there is no need to externally connect an air pump, improving energy efficiency; By arranging a chemical feed pipe 55 on the circumferential surface of the feed pipe 44, when the staff treats the wastewater, the prepared wastewater treatment chemical liquid can be conveyed into the aeration device 43 through the chemical feed pipe 55 and the feed pipe 44 by an external chemical liquid conveyor. At the same time, when the piston gasket 31 resets, the conveyance of its compressed air can further discharge the residual treatment chemical liquid in the feed pipe 44.

[0023] A water delivery pipe 46 is provided on the side wall of the pretreatment tank 11. A water outlet pipe 47 is fixedly communicated with the side wall of the pretreatment tank 11 on the side far from the water delivery pipe 46. An electric control valve 48 is provided at the lower end of the water outlet pipe 47. A third one-way valve 49 is provided at the end of the circulation pipe 25, and the third one-way valve 49 is fixedly communicated with the pretreatment tank 11; By setting the water outlet pipe 47 and the electric control valve 48, after the wastewater finishes treating the fibers inside the pretreatment tank 11, the staff can use the electric control valve 48 to convey the pretreated sewage, and by setting the third one-way valve 49, the wastewater after being squeezed by the filtering structure 16 can be discharged into the pretreatment tank 11, while preventing the wastewater inside the pretreatment tank 11 from flowing back.

[0024] Working principle: First step, during use, the staff can first turn on the motor 15, so that the motor 15 drives the driving roller 13 to rotate, and then drives the synchronous belt 14 to rotate around the outside of the driving roller 13. At this time, the staff can transport the wastewater into the pretreatment tank 11 through the water delivery pipe 46. At this time, the rotation of the synchronous belt 14 will drive the filtering structure 16 to move together, so that the scraping comb plate 52 on the filtering structure 16 takes away part of the wastewater and part of the fibers mixed in the wastewater. At the same time, whenever the filtering structure 16 rotates to the area of the top wheel 17, the top bar 53 on the filtering structure 16 will actively hit the top wheel 17, and through the flexible connection of the spring 54, the top bar 53 drives the scraping comb plate 52 to move downward inside the slide rail bracket 51, so that the fibers remaining on the scraping comb plate 52 are scraped off by the slide rail bracket 51, avoiding the fibers remaining on the scraping comb plate 52, and through the blocking and limiting of the second baffle 19 and the first baffle 18, it can be ensured that the fibers are scraped onto the second baffle 19 and the extrusion cavity 23, and the filtering structure 16 and the wastewater with the fibers being extruded will flow into the pretreatment tank 11 through the circulation pipe 25; Second step, when the output shaft of the motor 15 rotates, at this time the motor 15 will drive the rotating rod 34 to rotate through the conveyor belt 35, so that the disc 36 and the eccentric shaft 37 on the disc 36 rotate, and a radial force is generated on the rotating shaft 33 through the connecting rod 38, pulling the slide bar 32 to complete the reciprocating motion of the crank, so that the slide bar 32 drives the extrusion block 29 to reciprocate between the extrusion cavity 23 and the side housing 27, and then the fibers inside the extrusion cavity 23 can be extruded, so that the liquid absorbed by the fibers is extruded. The extruded liquid will flow into the pretreatment tank 11 through the circulation pipe 25. At the same time, when the extrusion block 29 extrudes the fibers to make a reciprocating motion, at this time some of the scraped fibers may fall on the upper surface of the extrusion block 29. By setting the scraping plate 21, when the extrusion block 29 returns to its original position, the scraping plate 21 can scrape the fibers down into the extrusion cavity 23 to ensure the treatment of the fibers; Third step, when the slide bar 32 drives the extrusion block 29 and the piston gasket 31 to move towards the extrusion cavity 23, at this time the movement of the piston gasket 31 will suck air into the side housing 27 through the second one-way valve 41, so that the air volume inside the side housing 27 increases and the pressure decreases. When the extrusion block 29 and the piston gasket 31 return to their original positions, the piston gasket 31 will squeeze the air inside the side housing 27, so that the air can be in a compressed state and be squeezed into the aeration device 43 through the first one-way valve 39 and the feed pipe 44, so that the aeration device 43 aerates the wastewater. When the bubbles generated by the aeration device 43 rise and discharge, the bubbles make the fibers float to the working area of the filtering structure 16 through the air flotation effect, enabling more fibers inside the wastewater to be fished out by the filtering structure 16.
