Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, and more specifically, relates to a wastewater treatment device for cotton yarn processing. Background Technology

[0002] Cotton yarn, as a crucial raw material in the textile industry, undergoes numerous processing steps, including opening, carding, drawing, roving, and spinning. Among these steps, particularly washing, dyeing, and rinsing, a large amount of wastewater is generated. Direct discharge of this wastewater would severely pollute water bodies, soil, and the ecological environment. This wastewater is characterized by high organic matter content, large pH fluctuations, and high color intensity. Therefore, its treatment requires a combination of processes to ensure compliance with discharge standards.

[0003] Chinese patent publication number "CN118851476A" discloses a wastewater treatment system for cotton fiber processing, including a sedimentation tank, an equalization tank, a shallow flotation tank, and a clear water tank. A wastewater inlet pipe is fixedly installed on the tank body. Through a designed cleaning mechanism, when a lot of coarse sludge accumulates on the surface of the filter screen during use, the drive motor is started. The drive motor drives the active roller to rotate, which in turn drives the transmission belt to rotate. At this time, the rotating transmission belt drives the long strip brush to move. The long strip brush can sweep the coarse sludge accumulated on the surface of the filter screen into the collection tank. Then, the active roller is opened, so that the scraper moves in the collection tank to move the coarse sludge located in the collection tank towards the discharge port. Then, the coarse sludge is discharged from the discharge port, which can clean the coarse sludge on the filter screen in a timely manner.

[0004] During later use, the device still had the following problems: it lacked a device to treat organic matter in cotton yarn processing wastewater. If it was discharged directly, it would easily cause eutrophication of the water body and disrupt the ecological balance of the water body; after the wastewater was treated, a lot of suspended solids would be generated, and the device lacked the relevant structure for treating suspended impurities. Summary of the Invention

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a wastewater treatment device for cotton yarn processing includes a stirred flocculation tank 1. By setting the stirred flocculation tank 1, the wastewater is subjected to neutralization treatment, air flotation treatment, and flocculation treatment. A valve 6 is fixedly connected to the bottom of the stirred flocculation tank 1, and a biological treatment tank 7 is fixedly connected to the bottom of the valve 6. By setting the biological treatment tank 7, the organic matter in the wastewater is degraded. A support frame 101 is also fixedly connected to the bottom of the stirred flocculation tank 1, and an installation arm 102 is fixedly connected to the top of the stirred flocculation tank 1. An adjustment mechanism 2 is fixedly installed on the installation arm 102.

[0018] By setting the regulating mechanism 2, the drive motor 203 rotates at high speed in the forward direction, causing wastewater to flow into the mixing flocculation tank 1 through the bottom through-hole 402 and the top through-hole 404. After colliding and mixing, the wastewater is discharged from the middle through-hole 403, which accelerates the mixing of wastewater and chemicals and allows the water to circulate in the mixing flocculation tank 1, avoiding the formation of mixing dead zones. When the drive motor 203 rotates slowly in the reverse direction, the mixed wastewater is further stirred and mixed. Water flows in through the bottom through-hole 402 and flows upward through the outlet bend 501D on the scum cleaning rotating frame 5, impacting the scum pusher 501C and carrying the scum into the filter ring 501B. After filtration, it returns to the mixing and flocculation tank 1. At the same time, the scraper 3 rotates to scrape and stir the inner wall, and the scum cleaning rotating frame 5 rotates to scrape the suspended solids on the top layer of the sewage. Meanwhile, the impurities in the filter ring 501B are pushed into the scum trough 103 by the propeller 502, completing the cleaning of the scum.

[0019] A scum trough 103 is fixedly connected to the outer top of the stirred flocculation tank 1, and a scum discharge pipe 104 is fixedly connected to the bottom of the scum trough 103. Impurities in the scum trough 103 are discharged from the scum discharge pipe 104. An aeration ring 105 is embedded in the inner wall of the bottom of the stirred flocculation tank 1. An air pump blows air out from the aeration ring 105 to perform air flotation treatment on the mixture of sewage and chemicals, treating a large number of fine suspended solids, emulsified oil and colloidal substances in the sewage. It also works with the scum cleaning rotating frame 5 to filter and collect the scum. A scraper 3 is rotatably connected to the bottom of the stirred flocculation tank 1. The scraper 3 can prevent some sediment from settling and clumping, thus avoiding blockage. At the same time, the sediment and flocs after the cotton yarn processing sewage is usually soft and loose. After being stirred, they are sucked in through the through hole 402 and pushed into the filter ring 501B to filter the sediment, flocs and scum.

[0020] The top of the scraper 3 is rotatably connected to a fixed guide tube 4, which is fixedly connected to the inner wall of the mixing flocculation tank 1. The top of the fixed guide tube 4 is rotatably connected to a scum cleaning rotating frame 5. By setting the scum cleaning rotating frame 5, the scum pusher plate 501C is driven to scrape and clean the suspended solids in the sewage. The water drawn up from the through hole 402 is guided to spray out from the outlet bend plate 501D. The sewage carrying the sediment washes the scum pusher plate 501C and pushes the scum on it into the filter ring 501B. like Figure 12 and Figure 13As shown, a support frame 701 is fixedly connected to the bottom of the biological treatment tank 7. The biological treatment tank 7 has a reaction chamber 702 inside, where activated sludge and sewage are mixed. The microorganisms in the activated sludge decompose the organic matter in the sewage. An aeration ring 8 is fixedly installed on the inner side wall of the reaction chamber 702. The aeration ring 8 aerates the reaction chamber 702. In conjunction with the spiral lifter 902, the activated sludge is broken up and dispersed, and then fully mixed with the sewage. A guide pipe 704 is fixedly connected inside the reaction chamber 702. The guide pipe 704, in conjunction with the spiral lifter 902, sucks the activated sludge at the bottom of the reaction chamber 702 into the opening 704A and pushes it upward. Driven by the dispersing disc 904, the sludge is dispersed.

[0021] An opening 704A is fixedly provided at the bottom of the guide pipe 704. A filter chamber 703 is provided at the bottom of the reaction chamber 702. After the organic matter in the sewage is treated, it is filtered by the filter cartridge 705 and discharged into the filter chamber 703, and then discharged from the valve 11. In order to prevent the activated sludge from clogging the filter cartridge 705 during the filtration process, the spiral lifting paddle 902 keeps rotating to scrape the filter cartridge 705 in time. The filter cartridge 705 is fixedly connected inside the filter chamber 703. A power mechanism 9 is also fixedly installed inside the biological treatment tank 7. A sealing assembly 10 is rotatably connected to the power mechanism 9. By setting the sealing component 10, when the biological treatment tank 7 is not performing treatment operations, the sealing component 10 seals the opening 704A to prevent excessive activated sludge from sliding into the filter cartridge 705 and clogging the filter holes; when the power mechanism 9 rotates, the spiral lifter 902 pushes the sewage in the guide pipe 704 upward, squeezing the dispersion disc 904 upward, and the dispersion disc 904 pushes the sealing component 10 upward, opening the opening 704A, and the activated sludge enters the spiral lifter 902 through the opening 704A for dispersion and mixing; a valve 2 11 is fixedly connected to the bottom of the biological treatment tank 7.

[0022] like Figure 4 and Figure 6 As shown, the adjustment mechanism 2 includes a mounting plate 201. A drive motor 203 is fixedly connected to the top center of the mounting plate 201. Push rod mechanisms 202 are fixedly installed on both sides of the top of the mounting plate 201. The push rod end of the push rod mechanism 202 is fixedly connected to the mounting arm 102. An adjustment transmission shaft 204 is fixedly connected to the output shaft of the drive motor 203. A transmission gear ring 204A is fixedly connected to the upper side wall of the adjustment transmission shaft 204. A retaining ring 204B is fixedly connected to the middle side wall of the adjustment transmission shaft 204. A positive propeller 204C is fixedly installed at the lower part of the retaining ring 204B. A retaining ring 204D is fixedly connected to the outer arm of the positive propeller 204C. A reverse propeller 204E is fixedly connected to the lower side wall of the adjustment transmission shaft 204. A transmission gear ring 204F is fixedly installed at the lower part of the reverse propeller 204E.

[0023] The push rod mechanism 202 extends the push rod, and the mounting plate 201 drives the drive motor 203 away from the mounting arm 102. At this time, the positive propeller 204C and the negative propeller 204E rotate at high speed. The sewage at the bottom of the mixing flocculation tank 1 is sucked in through the through hole 402 and through hole 3 404 and sprayed out through the through hole 2 403. The push rod mechanism 202 retracts the push rod, and the mounting plate 201 drives the drive motor 203 to approach the mounting arm 102. At this time, the transmission gear ring 204F meshes with the tooth groove 301. The negative propeller 204E lowers below the through hole 402, and the retaining ring 204D moves downward to block the through hole 2 403. B blocks the lower half of the through hole 3 404 downwards. At this time, the propeller 204C rotates slowly in the opposite direction, sucking in sewage and flocculents from the through hole 1 402, into the inlet tank 501E from the upper half of the through hole 3 404, and through the water channel 501F, sprayed from the outlet bend plate 501D onto the scum pusher plate 501C, and into the filter ring 501B. With the rotation of the mounting frame 501, under the condition that the bevel gear 1 405 and the bevel gear 2 503 mesh with each other, the bevel gear 2 503 drives the propeller 502 to rotate, pushing the scum, flocculent impurities, etc. on the filter ring 501B into the scum tank 103, completing the cleaning operation.

[0024] like Figure 7 As shown, the scraper 3 has a toothed groove 301 fixedly opened in the center. The toothed groove 301 is engaged with the transmission gear ring 204F. After the two mesh, the scraper 3 rotates under the drive of the drive motor 203, agitating the sediment and scraping the inner wall. The fixed guide tube 4 has a fixed support arm 401 fixedly connected to the outer wall. The fixed support arm 401 is fixedly connected to the inner wall of the stirring flocculation tank 1. The lower side wall of the fixed guide tube 4 has multiple sets of through holes 402, the middle side wall of the fixed guide tube 4 has multiple sets of through holes 403, the upper side wall of the fixed guide tube 4 has multiple sets of through holes 404, and the top of the fixed guide tube 4 is fixedly connected to a bevel gear 405.

[0025] like Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the scum cleaning rotating frame 5 includes a mounting frame 501, which is rotatably connected to the top of the fixed guide cylinder 4. A toothed groove 501A is fixedly opened at the center of the top of the mounting frame 501. The toothed groove 501A cooperates with the transmission gear ring 204A. When the two mesh, the power of the drive motor 203 can be transmitted to the scum cleaning rotating frame 5, driving the mounting frame 501 to rotate and treat suspended impurities. Filter rings 501B extend outward from both sides of the mounting frame 501. A push propeller 502 is rotatably connected to both side walls of the mounting frame 501. A bevel gear 503 is fixedly connected to one end of the push propeller 502. The bevel gear 503 meshes with the bevel gear 405. When the scum cleaning rotating frame 5 rotates, the bevel gear 503 drives the push propeller 502 to rotate, pushing away the impurities on the filter rings 501B and pushing the filtered impurities into the scum tank 103.

[0026] The filter ring 501B extends forward to form a scum pusher plate 501C. Multiple sets of guide plates are fixedly connected to the upper surface of the scum pusher plate 501C. An outlet bend plate 501D is fixedly connected to the front of the scum pusher plate 501C. A water passage trough 501F is fixedly opened inside the scum pusher plate 501C. An inlet tank 501E is fixedly connected to the bottom of the mounting bracket 501, and the inlet tank 501E is connected to the water passage trough 501F. The wastewater mixture entering the inlet tank 501E is sprayed out through the water passage trough 501F and outwards towards the scum pusher plate 501C, cleaning the suspended impurities on the scum pusher plate 501C and allowing them to smoothly enter the filter ring 501B.

[0027] like Figure 14 As shown, the power mechanism 9 includes a second drive motor 901 and a dispersing disc 904. The second drive motor 901 is fixedly connected to the top of the biological treatment tank 7. The output shaft of the second drive motor 901 is fixedly connected to a spiral lifting paddle 902. The spiral lifting paddle 902 is rotatably connected to the inner wall of the guide pipe 704 and the inner wall of the filter cylinder 705. A transmission gear ring 902A is fixedly connected to the upper side wall of the spiral lifting paddle 902. A sealing cover 902B is fixedly installed on the upper part of the transmission gear ring 902A. A compression spring 903 is fixedly connected to the inner wall of the top of the sealing cover 902B. By setting up the power mechanism 9, the spiral lifting paddle 902 lifts the wastewater and activated sludge from the guide pipe 704 and the filter cylinder 705 upwards to the dispersing disc 904. Under the push of the dispersing disc 904, the wastewater and activated sludge are radially diffused, allowing the microorganisms to fully contact the organic matter in the wastewater.

[0028] like Figure 16 and Figure 17As shown, a toothed groove 904A is fixedly provided on the inner wall of the center of the dispersing turntable 904. The toothed groove 904A is slidably connected to the transmission gear ring 902A. The dispersing turntable 904 can slide axially on the spiral lifting paddle 902 and rotate under the drive of the spiral lifting paddle 902 to disperse the activated sludge. A sealing lower cover 904B is fixedly connected to the top of the dispersing turntable 904. The sealing lower cover 904B and the sealing upper cover 902B are in sliding contact. By setting the sealing lower cover 904B and the sealing upper cover 902B, the pressure spring 903 is sealed and protected to prevent sewage from corroding the pressure spring 903. The other end of the pressure spring 903 is fixedly connected to the top of the dispersing turntable 904. Under the push of the pressure spring 903, the dispersing turntable 904 keeps the top of the guide pipe 704 close.

[0029] like Figure 15 As shown, the sealing assembly 10 includes a connecting ring 1001, which is rotatably connected to the outer wall of the dispersing disc 904. A connecting rod 1002 is fixedly connected to the bottom of the connecting ring 1001, and a sealing retaining ring 1003 is fixedly connected to the other end of the connecting rod 1002. The sealing retaining ring 1003 is slidably connected to the outer wall of the guide pipe 704. The sealing retaining ring 1003 cooperates with the opening 704A. When the dispersing disc 904 is held to its lowest position under the push of the compression spring 903, the sealing retaining ring 1003 blocks the opening 704A to prevent the activated sludge from passing through the opening 704A and falling into the filter cylinder 705. When the spiral lifting paddle 902 starts to rotate, the sewage pushes the dispersing disc 904 upward. The dispersing disc 904 moves upward and drives the sealing assembly 10, opening the opening 704A. The activated sludge and the sewage at the bottom are spirally lifted up and dispersed again.

[0030] The operating principle of stirred flocculation tank 1 is as follows: Figure 18 and Figure 19 As shown: 1. Pour cotton yarn processing wastewater and neutralizing agent into the stirring flocculation tank 1, start the drive motor 203, adjust the transmission shaft 204 to drive the positive propeller 204C and the negative propeller 204E to rotate, and draw the wastewater mixture into the fixed guide tube 4 through the through hole 3 404 and through hole 1 402, where it will collide and mix, and then be discharged through the through hole 2 403. After neutralization, add flocculant to mix the flocculant and wastewater thoroughly again. 2. Air is introduced into the aeration buffer to perform air flotation treatment on the sewage. The push rod mechanism 202 is adjusted to retract the push rod, and the drive motor 203 is rotated in the opposite direction. The lower half of the through hole 403 and the through hole 404 are blocked. The propeller 204C sucks the sewage and flocculated sediment from the bottom through the through hole 402 and pushes it into the inlet tank 501E through the upper half of the through hole 404. It is then sprayed from the outlet bend 501D through the water channel 501F to the filter ring 501B for filtration. 3. At the same time, the scraper 3 and the scum cleaning frame 5 mesh with the adjusting drive shaft 204 to agitate the flocs deposited at the bottom of the tank and collect and filter the suspended solids floating on the top of the sewage.

[0031] Operating principle of biological treatment tank 7: 1. Wastewater that has undergone neutralization and flocculation treatment enters the biological treatment tank 7 through valve 6. As the water level in the tank gradually rises, the wastewater flows in from the gap between the dispersion disc 904 and the guide pipe 704 and fills the guide pipe 704. 2. Start the drive motor 901. The spiral lifting paddle 902 drives the sewage in the guide pipe 704 to flow upward, pushing the dispersion disc 904 open. The dispersion disc 904 overcomes the thrust of the compression spring 903 and widens the gap with the guide pipe 704. 3. The sealing component 10 is pushed upward, the opening 704A is opened, and the activated sludge and bottom sewage continuously enter the guide pipe 704 and are pushed upward by the spiral lifting paddle 902. Under the disturbance of the redispersing disc 904, radial diffusion occurs, which promotes full contact between the microorganisms in the activated sludge and the sewage. Air is introduced into the biological treatment tank 7 through the aeration ring 8 to ensure the aerobic decomposition treatment of organic matter by the microorganisms. 4. Open valve 2 11. The treated wastewater enters the filter chamber 703 through the filter cylinder 705 and is discharged from the bottom valve 2 11. Because the filter cylinder 705 is set up, the activated sludge is blocked and prevented from being lost. Because the spiral lifting paddle 902 continuously scrapes the inner wall of the filter cylinder 705 upward, the activated sludge will not be in contact with the filter holes for a long time, thus preventing the filter holes from being blocked. 5. After processing is completed, drive motor 901 is turned off, and the dispersing turntable 904 is pushed down by the compression spring 903, which drives the sealing assembly 10 to descend and block the opening 704A, so as to prevent a large amount of activated sludge from depositing in the filter cartridge 705 through the opening 704A, which would cause the filter holes to become clogged during the next use and affect the filtration efficiency.

[0032] This invention utilizes an adjustment mechanism 2 to drive a motor 203 to rotate at high speed in the forward direction, causing the wastewater to collide and mix, thus accelerating the mixing of wastewater and chemicals. When the motor 203 rotates slowly in the reverse direction, the mixed wastewater is discharged upwards from the outlet bend 501D on the scum cleaning rotating frame 5, impacting the scum pusher 501C and carrying the scum into the filter ring 501B, thus completing the scum cleaning. The scum cleaning rotating frame 5 drives the scum pusher 501C to scrape and clean suspended solids in the wastewater. Water drawn up from the through-hole 402 is guided and sprayed out from the outlet bend 501D, carrying the scum... The wastewater from the sediment flushes the scum pusher plate 501C, pushing the scum onto the plate into the filter ring 501B. When the biological treatment tank 7 is not in operation, the sealing assembly 10 blocks the opening 704A to prevent activated sludge from slipping into the filter cylinder 705 and clogging the filter holes. When the power mechanism 9 rotates, the spiral lifter 902 pushes the wastewater in the guide pipe 704 upwards, squeezing the dispersion disc 904. The dispersion disc 904 then pushes the sealing assembly 10 upwards, opening the opening 704A. The activated sludge then enters the spiral lifter 902 through the opening 704A for dispersion and mixing.

The sealing retaining ring is slidably connected to the outer wall of the guide tube, and the sealing retaining ring cooperates with the opening at the bottom of the guide tube. The push rod mechanism can extend and retract to drive the mounting plate and drive motor 1 to move axially. When the push rod extends, the mounting plate drives the drive motor 1 away from the mounting arm, and the positive and negative propellers rotate at high speed. The sewage at the bottom of the mixing flocculation tank is sucked into the fixed guide tube through through holes 1 and 3 and then collides and mixes before being discharged through through hole 2. When the push rod retracts, the mounting plate drives the drive motor 1 to approach the mounting arm. The transmission gear ring 2 meshes with the tooth groove 1 of the scraper and the transmission gear ring 1 meshes with the tooth groove 2 of the mounting frame. The retaining ring 2 moves downward to block through hole 2, and the retaining ring 1 blocks the lower half of through hole 3.

The sewage is sprayed from the outlet bend plate through the water channel to the scum push plate and into the filter ring. Furthermore, the compression spring pushes the dispersing turntable to keep it close to the top of the guide pipe, thereby causing the sealing ring to block the opening at the bottom of the guide pipe; when the spiral lifter rotates, the sewage in the guide pipe pushes the dispersing turntable upward, causing the dispersing turntable to move the sealing assembly upward and open the opening, and the activated sludge enters the spiral lifter through the opening for dispersion and mixing.
