Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and specifically to a textile printing and dyeing wastewater treatment device. Background Art

[0002] A textile printing and dyeing wastewater treatment device is a device specifically used for treating wastewater generated during the textile printing and dyeing process.

[0003] The patent with the patent announcement number CN209143919U relates to a printing and dyeing box. A conveying pipe is fixedly installed at the bottom of the printing and dyeing box. A water pump is fixedly installed at one end of the conveying pipe away from the printing and dyeing box. A wastewater treatment box is arranged on the right side of the printing and dyeing box. In this textile printing and dyeing wastewater treatment device, through the cooperation of a driving wheel and a driven wheel, the blades fixed on the gear rotate to cut sundries such as waste yarns brought in when textile wastewater enters, and will not block the leaking through holes. Through the cooperation of a negative electrode and a positive electrode, the water filtered into the electrolytic water reaction box is subjected to electrolytic water treatment, effectively purifying the wastewater. An air diffuser pipe is provided, and the gas introduced makes the wastewater quickly diffuse from the negative electrode tube to the positive electrode tube. When the wastewater diffuses in the negative electrode tube, an oxidation-reduction reaction occurs, reducing the occurrence of side reactions such as oxygen evolution or hydrogen evolution, increasing the yield of free radicals, thereby improving the current efficiency and reducing energy consumption.

[0004] In the above patent, the blades fixed on the gear rotate to cut sundries such as waste yarns brought in when textile wastewater enters, and will not block the leaking through holes. However, there are still problems. When the blades cut the waste yarns, the blades may be wound, resulting in the scrapping of the blades, and no matter how these things are cut, they still cannot be effectively removed inside. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a textile printing and dyeing wastewater treatment device, which solves the problems raised in the above background art.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A textile printing and dyeing wastewater treatment device includes a sewage tank. A motor is arranged on the top of the sewage tank. A rotating shaft is fixedly installed on the right side of the motor. A pre-cleaning mechanism is arranged inside the sewage tank; Among them, the pre-cleaning mechanism includes a push rod, an inclined panel, a roller, an arc column, and a square plate. The push rod is fixedly installed on the right side of the rotating shaft. The inclined panel is fixedly installed on the top of the sewage tank. The roller is rotatably installed inside the sewage tank. The arc column is rotatably installed on the circumferential surface of the roller. The square plate is fixedly installed on the side of the arc column close to the motor; Among them, a recycling mechanism for recycling rags and a collecting device for fiber recycling inside the sewage tank are provided on the front of the sewage tank. When the rags fall to the top of the inclined panel, since the push rod is rotating, the rags at the top of the inclined panel will be pushed to the next step. Since the rags in the sewage may be too large, when the rags between the two arc columns are too large, the rags will be scraped off due to the convex plate.

[0007] According to the above technical solution, the cleaning mechanism further includes a convex plate, a transmission rod and a gear. The convex plate is fixedly installed on the top of the inclined panel. The transmission rod is arranged at the back of the motor. The gear is fixedly installed at one end of the roller close to the transmission rod. When the rotating shaft rotates clockwise, it will drive the transmission rod to rotate counterclockwise through the belt. When the transmission rod rotates, it will drive the gear to rotate clockwise.

[0008] According to the above technical solution, the square plate is a flexible plate. The transmission rod contacts the gear, and the arc column contacts the inclined panel. When the roller continues to rotate, the arc column will contact the top of the inclined panel. When the arc column contacts the top of the inclined panel, the rags on the arc column will be scraped onto the top of the inclined panel.

[0009] According to the above technical solution, the recycling device includes a collecting box, a reciprocating lead screw, a square column, a push plate, a lower toothed plate, a pushing plate, a toothed column and an upper toothed plate. The collecting box is fixedly installed on the front of the sewage tank. The reciprocating lead screw is rotatably installed at one end of the roller away from the transmission rod. The square column is threadedly installed on the circumferential surface of the reciprocating lead screw. The push plate is fixedly installed at the bottom of the square column. The lower toothed plate is fixedly installed on the side of the push plate close to the collecting box. The toothed column is rotatably installed on the inner wall of the collecting box. The pushing plate is slidably installed on the inner wall of the collecting box. The upper toothed plate is slidably installed on the inner wall of the collecting box. When the roller rotates, it will drive the reciprocating lead screw to rotate. When the reciprocating lead screw rotates, it will drive the square column to move reciprocally. When the square column moves reciprocally, it will drive the push plate at the bottom of the square column to move reciprocally. When the push plate moves away from the roller, it will drive the lower toothed plate to move.

[0010] According to the above technical solution, the recycling device further includes an L-shaped rod, a protection plate, an elastic telescopic block and a limiting plate. One end of the L-shaped rod is fixedly installed at one end of the toothed column close to the push plate, and the other end of the L-shaped rod is fixedly connected to the bottom of the pushing plate. The protection plate is fixedly installed on the inner wall of the collecting box. The elastic telescopic block is fixedly installed on the outer wall of the collecting box. The limiting plate is rotatably installed on the front of the collecting box. When there are too many rags, the squeezed rags will be squeezed into the elastic telescopic block. When the internal pressure of the elastic telescopic block is too large, it will drive the elastic telescopic block to move outwards.

[0011] According to the above technical solution, the lower toothed plate meshes with the toothed column, the toothed column meshes with the upper toothed plate, a clockwork spring is arranged between the limiting plate and the collection box, the elastic telescopic block contacts the limiting plate, and when the limit of the collection box is released, the debris inside the collection box can be cleaned, and at the same time, the protection plate will protect the toothed column below.

[0012] According to the above technical solution, the collection device includes an irregular plate, a scraping plate, a thin plate, a collection sieve box, a rounded plate, a long push column, and a flat plate. One end of the irregular plate is fixedly installed on the top of the square column, the scraping plate is fixedly installed at the other end of the irregular plate, one end of the thin plate is fixedly installed on the top of the scraping plate, the collection sieve box is fixedly installed at the other end of the thin plate, the flat plate is fixedly installed at one end of the scraping plate close to the collection sieve box, the rounded plate is fixedly installed on the side of the flat plate close to the collection sieve box, and the long push column is rotatably installed at the bottom of the inner wall of the sewage tank. When the irregular plate moves, it will drive the scraping plate to move. When the scraping plate moves, it will stir the sewage inside the sewage tank to prevent large pieces of rags from sinking to the bottom.

[0013] According to the above technical solution, the long push column contacts the flat plate, and the rounded plate contacts the long push column. When the thin plate moves, it will drive the collection sieve box to move. When the collection sieve box moves, it will collect the fibers falling off the long push column to prevent the fibers from flowing in.

[0014] The present invention provides a textile printing and dyeing wastewater treatment device. It has the following beneficial effects: (1) In this invention, when the push rod rotates, it will drive the rags above the inclined panel to be pushed downward, which can help transfer the rags above and prevent them from affecting and hindering the subsequent cleaning of rags. When the roller rotates, it will drive the arc column to rotate. When the arc column rotates, it will drive the rags to flip. At the same time, the square plate on the arc column will prevent the rags from falling when rotating on the arc column, and can effectively collect and clean the rags.

[0015] (2) In this invention, when the reciprocating lead screw rotates, it can drive the square column to move. When the square column moves, it will drive the push plate to move. When the push plate moves, it can squeeze the rags inside the collection box. At first, it will squeeze and dehydrate the rags. When the rags accumulate too much, it will push the rags out. When the lower toothed plate moves, it will drive the toothed column to rotate. When the toothed column rotates, it will drive the upper toothed plate to move. When the upper toothed plate moves, it will drive the L rod to move. When the L rod moves, it will push the pushing plate outward and push the rags inside outward to prevent the rags from conflicting with the push plate.

[0016] (3) In this invention, when the irregular plate moves, it drives the scraping plate to move. When the sewage in the sewage tank tumbles, it can prevent a large amount of rags from depositing at the bottom of the sewage. When the flat plate moves, it drives the long push column to move. When the rounded plate moves, it drives the long push column to fall completely flat. At the same time, the collection sieve box collects the fibers on the long push column, preventing the fibers in the sewage tank from flowing into the next link. It also avoids the need for workers to operate on the sewage in the sewage tank multiple times, reducing the work process and saving time. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 7, an embodiment of the present invention is: a textile printing and dyeing wastewater treatment device, including a sewage tank 1, a motor 2 is arranged on the top of the sewage tank 1, a rotating shaft 3 is fixedly installed on the right side of the motor 2, and a pre-cleaning mechanism is arranged inside the sewage tank 1; Among them, the pre-cleaning mechanism includes a push rod 4, an inclined panel 5, a drum 6, an arc column 7 and a square plate 8. The push rod 4 is fixedly installed on the right side of the rotating shaft 3, the inclined panel 5 is fixedly installed on the top of the sewage tank 1, the drum 6 is rotatably installed inside the sewage tank 1, the arc column 7 is rotatably installed on the circumferential surface of the drum 6, and the square plate 8 is fixedly installed on the side of the arc column 7 close to the motor 2. When the arc column 7 rotates, it will drive the shredded cloth to flip. At the same time, the square plate 8 on the arc column 7 can prevent the shredded cloth from falling when rotating on the arc column 7, and can effectively collect and clean the shredded cloth.

[0021] The cleaning mechanism further includes a convex plate 9, a transmission rod 10 and a gear 11. The convex plate 9 is fixedly installed on the top of the inclined panel 5, the transmission rod 10 is arranged on the back of the motor 2, and the gear 11 is fixedly installed at one end of the drum 6 close to the transmission rod 10. When the rotating shaft 3 rotates clockwise, it will drive the transmission rod 10 to rotate counterclockwise through a belt. When the transmission rod 10 rotates, it will drive the gear 11 to rotate clockwise.

[0022] The square plate 8 is a flexible plate. The transmission rod 10 is in contact with the gear 11, and the arc column 7 is in contact with the inclined panel 5. When the drum 6 continues to rotate, the arc column 7 will contact the top of the inclined panel 5. When the arc column 7 contacts the top of the inclined panel 5, the shredded cloth on the arc column 7 will be scraped onto the top of the inclined panel 5.

[0023] When this embodiment works: Place the sewage tank 1 in a suitable position and start the motor 2. When the motor 2 starts, it will drive the rotating shaft 3 to rotate clockwise. When the rotating shaft 3 rotates clockwise, it will drive the push rod 4 to rotate. When the rotating shaft 3 rotates clockwise, it will drive the transmission rod 10 to rotate counterclockwise through a belt. When the transmission rod 10 rotates, it will drive the gear 11 to rotate clockwise. When the gear 11 rotates clockwise, it will drive the arc column 7 on the circumferential surface of the drum 6 to rotate. When the arc column 7 rotates, it will salvage the large shredded cloth in the sewage in the sewage tank 1. When shredded cloth is salvaged on the arc column 7, since there is a square plate 8 above the arc column 7, when the arc column 7 rotates to the top, the shredded cloth can be prevented from falling onto the drum 6. When the drum 6 continues to rotate, the arc column 7 will contact the top of the inclined panel 5. When the arc column 7 contacts the top of the inclined panel 5, the shredded cloth on the arc column 7 will be scraped onto the top of the inclined panel 5. When the shredded cloth falls onto the top of the inclined panel 5, since the push rod 4 is rotating, the shredded cloth on the top of the inclined panel 5 will be pushed to the next step. Since the shredded cloth in the sewage may be too large, when the shredded cloth between two arc columns 7 is too large, the shredded cloth will be scraped off due to the convex plate 9.

[0024] Please refer to Figures 1 - 7 , based on the above embodiments, in another embodiment of the present invention, a recycling mechanism for recycling rags and a collecting device for fiber recycling inside the sewage tank 1 are provided on the front surface of the sewage tank 1. The recycling device includes a collecting box 21, a reciprocating screw rod 22, a square column 23, a push plate 24, a lower toothed plate 25, a pushing plate 26, a toothed column 27, and an upper toothed plate 28. The collecting box 21 is fixedly installed on the front surface of the sewage tank 1. The reciprocating screw rod 22 is rotatably installed at one end of the roller 6 away from the transmission rod 10. The square column 23 is threadedly installed on the circumferential surface of the reciprocating screw rod 22. The push plate 24 is fixedly installed at the bottom of the square column 23. The lower toothed plate 25 is fixedly installed on the surface of the push plate 24 close to the collecting box 21. The toothed column 27 is rotatably installed on the inner wall of the collecting box 21. The pushing plate 26 is slidably installed on the inner wall of the collecting box 21. The upper toothed plate 28 is slidably installed on the inner wall of the collecting box 21. When the upper toothed plate 28 moves, it will drive the L rod 29 to move. When the L rod 29 moves, it will push the pushing plate 26 outwards to push the rags inside out, avoiding the rags from colliding with the push plate 24.

[0025] The recycling device further includes an L rod 29, a protection plate 30, an elastic telescopic block 31, and a limiting plate 32. One end of the L rod 29 is fixedly installed at one end of the toothed column 27 close to the push plate 24. The other end of the L rod 29 is fixedly connected to the bottom of the pushing plate 26. The protection plate 30 is fixedly installed on the inner wall of the collecting box 21. The elastic telescopic block 31 is fixedly installed on the outer wall of the collecting box 21. The limiting plate 32 is rotatably installed on the front surface of the collecting box 21. When there are too many rags, the squeezed rags will be squeezed into the elastic telescopic block 31. When the pressure inside the elastic telescopic block 31 is too large, it will drive the elastic telescopic block 31 to move outwards.

[0026] The lower toothed plate 25 meshes with the toothed column 27. The toothed column 27 meshes with the upper toothed plate 28. A clockwork spring is provided between the limiting plate 32 and the collecting box 21. The elastic telescopic block 31 contacts the limiting plate 32. When the limit of the collecting box 21 is released, the debris inside the collecting box 21 can be cleaned, and at the same time, the protection plate 30 will protect the toothed column 27 below.

[0027] The collection device includes an irregular plate 41, a scraping plate 42, a thin plate 43, a collection sieve box 44, a rounded plate 45, a long push rod 46, and a flat plate 47. One end of the irregular plate 41 is fixedly installed at the top of the square column 23, the scraping plate 42 is fixedly installed at the other end of the irregular plate 41, one end of the thin plate 43 is fixedly installed at the top of the scraping plate 42, the collection sieve box 44 is fixedly installed at the other end of the thin plate 43, the flat plate 47 is fixedly installed at one end of the scraping plate 42 close to the collection sieve box 44, the rounded plate 45 is fixedly installed on the side of the flat plate 47 close to the collection sieve box 44, the long push rod 46 is rotatably installed at the bottom of the inner wall of the sewage tank 1, and the collection sieve box 44 will collect the fibers on the long push rod 46, preventing the fibers inside the sewage tank 1 from flowing into the next step. At the same time, it can also prevent the staff from operating the sewage inside the sewage tank 1 multiple times, reducing the work process and saving time.

[0028] The long push rod 46 contacts the flat plate 47, and the rounded plate 45 contacts the long push rod 46. When the thin plate 43 moves, it will drive the collection sieve box 44 to move. When the collection sieve box 44 moves, it will collect the fibers falling off the long push rod 46 to prevent the fibers from flowing in.

[0029] During the operation of this embodiment: When the rags pushed by the push rod 4 at the top of the inclined panel 5 enter the collection box 21, the rags will be stacked and dewatered. When the roller 6 rotates, it will drive the reciprocating lead screw 22 to rotate. When the reciprocating lead screw 22 rotates, it will drive the square column 23 to move reciprocally. When the square column 23 moves reciprocally, it will drive the push plate 24 at the bottom of the square column 23 to move reciprocally. When the push plate 24 moves away from the roller 6, it will drive the lower toothed plate 25 to move. When the lower toothed plate 25 moves, it will drive the toothed column 27 to rotate. When the toothed column 27 rotates, it will drive the upper toothed plate 28 to move in the direction close to the roller 6. When the upper toothed plate 28 moves, it will drive the L rod 29 to move. When the L rod 29 moves, it will drive the pushing plate 26 to move. And because the bottom of the push plate 24 is a movable plate and the bottom plate is rotationally connected to the right side of the upper plate, the push plate 24 can only push the rags away from the roller 6 and will not affect the rags close to the roller 6. When the push plate 24 moves towards the roller 6, it will drive the lower toothed plate 25 to move. When the lower toothed plate 25 moves, it will drive the toothed column 27 to rotate. When the toothed column 27 rotates, it will drive the upper toothed plate 28 to move. When the upper toothed plate 28 moves, it will drive the L rod 29 to move. When the L rod 29 moves, it will drive the pushing plate 26 to move downward. When the pushing plate 26 moves downward, it will push the garbage at the bottom outward to prevent the push plate 24 from being blocked by the bottom garbage when it comes back, so that the push plate 24 can push all the rags during the second cleaning. When the push plate 24 pushes the rags away from the roller 6, it will first squeeze the rags to squeeze out the liquid inside. When there are too many rags, the squeezed rags will be squeezed into the elastic telescopic block 31. When the internal pressure of the elastic telescopic block 31 is too large, it will drive the elastic telescopic block 31 to move outward. When the elastic telescopic block 31 moves outward, it will drive the limit plate 32 to move. When the limit plate 32 moves, the limit on the collection box 21 will be released. After the limit on the collection box 21 is released, the debris inside the collection box 21 can be cleaned, and at the same time, the protection plate 30 will protect the toothed column 27 below.

[0030] When the square column 23 moves, it will drive the irregular plate 41 to move. When the irregular plate 41 moves, it will drive the scraping plate 42 to move. When the scraping plate 42 moves, it will stir the sewage in the sewage tank 1 to prevent large pieces of rags from sinking to the bottom. At the same time, since there are still many fibers in the sewage tank 1 that have not been cleaned, these fibers will wrap around the long push column 46. When the scraping plate 42 moves, it will drive the flat plate 47 to move. When the flat plate 47 moves, it will push the long push column 46. When the long push column 46 is pushed, the rounded corner plate 45 will also push the long push column 46 again until the long push column 46 falls horizontally. At the same time, when the scraping plate 42 moves, it will drive the thin plate 43 to move. When the thin plate 43 moves, it will drive the collection sieve box 44 to move. When the collection sieve box 44 moves, it will collect the fibers that have fallen off the long push column 46 to prevent the fibers from flowing in.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
