Description

Technical Field

[0001] The invention belongs to the technical field of textile printing and dyeing wastewater treatment, and in particular relates to a textile printing and dyeing wastewater treatment system. Background Art

[0002] There are many ways to treat printing and dyeing wastewater, among which biological treatment is considered to be the most effective and environmentally friendly treatment method. In the biological treatment method, activated sludge is placed in the sewage, and there are a large number of complex microorganisms in the activated sludge. The complex microorganisms in the activated sludge come into contact with the organic waste in the wastewater, causing the organic waste in the wastewater to be degraded.

[0003] However, the above method has some shortcomings. There are not only a large number of organic substances such as fabric residues and lint fibers in textile printing and dyeing wastewater, but also harmful chemicals. The microorganisms in the activated sludge can only degrade organic matter and do not react with chemical substances. Generally, in order to screen the fabric residues and lint fibers in textile printing and dyeing wastewater, it is necessary to screen the fabric residues first, so that the wastewater after the initial screening enters the next purification tank, and then screen the lint fibers. The separate screening increases the number of purification tanks used, thereby increasing the cost of use. In addition, during the screening of the lint fibers, the screening box is used for a long time, and a large amount of lint fibers are easily deposited inside, which needs to be replaced in time. During the replacement process, the screening of the lint fibers needs to be suspended for a long time, thereby reducing the efficiency of textile printing and dyeing wastewater treatment. To this end, we provide a textile printing and dyeing wastewater treatment system to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a textile printing and dyeing wastewater treatment system, which ensures the screening effect and sewage fluidity inside the first screening box and the second screening box by alternately replacing the first screening box and the second screening box, and completes the screening of fabric residues and fluff fibers at one time through the coordinated work of the first screening component and the second screening component, without the need to use multiple purification tanks in steps, effectively reducing the use cost and improving the efficiency of sewage purification, and solves the existing screening of fabric residues and fluff fibers in textile printing and dyeing wastewater. It is necessary to screen the fabric residue first, so that the sewage after the initial screening enters the next purification tank, and then the fluff fibers are screened. The separate screening increases the number of purification tanks used, thereby increasing the use cost, and in the process of screening the fluff fibers, the screening box is used for a long time, and a large amount of fluff fibers are easily deposited inside, which needs to be replaced in time.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1-13The present invention provides the following technical solutions: a textile printing and dyeing wastewater treatment system, comprising a support assembly 1; the support assembly 1 comprises a base 101, a water reservoir 102 is fixedly connected to the top of the base 101, a cushion 103 is fixedly connected to the top of the base 101, and a first screening assembly 2 is fixedly matched to the top of the cushion 103; the first screening assembly 2 comprises a guide plate 201 fixedly connected to the top of the cushion 103, a first vertical plate 202 is symmetrically fixedly connected to the top of the guide plate 201, the first screening assembly 2 also comprises a second vertical plate 203 fixedly connected to the top of the cushion 103, and a first rotating shaft 204 is rotatably connected between the two first vertical plates 202. A second rotating shaft 205 is rotatably connected between the two second vertical plates 203, and conveying rollers 206 are fixedly connected to the outer walls of the first rotating shaft 204 and the second rotating shaft 205. A conveying belt 207 is transmitted between the two conveying rollers 206, and a plurality of paddles 208 are evenly and fixedly connected to the outer wall of the conveying belt 207; a second screening assembly 3 is rotatably matched with one side of the cushion seat 103, and the second screening assembly 3 includes a rotating rod 301 rotatably connected to the cushion seat 103, and a turntable 302 is fixedly connected to the end of the rotating rod 301, and a first screening box 303 and a second screening box 304 arranged at 120° are slidably connected to one side of the turntable 302.

[0035] The operation process of this embodiment is as follows: first, the first spur gear 209 is controlled to rotate counterclockwise, so that the first spur gear 209 drives the conveying roller 206 to rotate counterclockwise through the second rotating shaft 205 (such as Figure 6 As shown in the figure, the conveyor belt 207 and the plurality of paddles 208 are driven to rotate counterclockwise, and then the sewage is poured onto the conveyor belt 207 from directly above the first screening component 2 through the external conveying pipe (a solenoid valve is provided on the conveying pipe to control the discharge of sewage). With the counterclockwise rotation of the conveyor belt 207 and the plurality of paddles 208, the fabric residue in the sewage is screened out by the paddles 208, and the sewage after the initial screening falls from the conveyor belt 207 onto the guide plate 201, and then the sewage flows along the guide plate 201 into the first screening box 303 and the second screening box 303 corresponding to the guide plate 201. In the screening box 304, the fluff fibers in the sewage are screened by the corresponding first screening box 303 and the second screening box 304, so as to remove impurities in the sewage, and provide a guarantee for the subsequent activated sludge to better purify the sewage. After the sewage passes through the first screening component 2 and the second screening component 3 and flows into the water reservoir 102, the sewage in the water reservoir 102 can be chemically purified to purify harmful substances in the sewage. After the chemical purification is completed, the sewage in the water reservoir 102 is transferred to the activated sludge tank, and the organic matter in the sewage is degraded by the activated sludge, so as to purify the sewage;

[0036] Initially, the first screening box 303 is fitted with the tail end of the guide plate 201. As the fluff fibers inside the first screening box 303 increase, the weight of the first screening box 303 exceeds the set threshold value. At this time, the solenoid valve on the external delivery pipe is controlled to start, so that the sewage stops being injected into the first screening component 2. After waiting for the water flow to stop flowing into the first screening component 2, the driven gear 307 is controlled to rotate, so that the driven gear 307 drives the rotating disk 302 to rotate through the rotating rod 301, so that the rotating disk 302 drives the first screening box 303 to move away from the guide plate 2. 01, synchronously causing the turntable 302 to drive the second screening box 304 to rotate toward the direction close to the guide plate 201, so that the second screening box 304 fits the tail end of the guide plate 201 (synchronously controlling the solenoid valve of the external delivery pipe so that the external delivery pipe continues to inject sewage), thereby realizing the replacement of the second screening box 304 with the first screening box 303, so that the fluff fibers in the first screening box 303 are dumped out (the inside of the first screening box 303 can be flushed with a water pipe to improve the cleanliness of the first screening box 303);

[0037] When the fluff fibers inside the second screening box 304 increase and the weight of the second screening box 304 exceeds the set threshold, the solenoid valve on the external delivery pipe is controlled to start, so that the sewage stops being injected into the second screening box 304, and the driven gear 307 is controlled to rotate in the opposite direction, so that the driven gear 307 drives the turntable 302 to rotate in the opposite direction through the rotating rod 301, so that the turntable 302 drives the second screening box 304 to rotate away from the guide plate 201, and synchronously drives the turntable 302 to rotate the first screening box 303 towards the guide plate 201, so that the first screening box 303 fits with the tail end of the guide plate 201 (synchronously controlling the solenoid valve of the external delivery pipe so that the external delivery pipe continues to inject sewage), thereby achieving the second screening box 304. By replacing the first screening box 303 with the second screening box 304, the fluff fibers in the second screening box 304 are dumped out (a water pipe can be used to flush the inside of the second screening box 304 to improve the cleanliness of the first screening box 303). By alternately replacing the first screening box 303 and the second screening box 304, the screening effect and sewage fluidity inside the first screening box 303 and the second screening box 304 are guaranteed, avoiding the replacement of a single screening box and affecting the efficiency of sewage filtration. Through the coordinated work of the first screening component 2 and the second screening component 3, the screening of fabric residues and fluff fibers is completed at one time, without the need to use multiple purification tanks in steps, effectively reducing the use cost and improving the efficiency of sewage purification.

[0038] For example 2, please refer to Figure 1-13, the second embodiment is improved on the basis of the first embodiment as follows: the support assembly 1 also includes a control box 104 fixedly connected to the top of the cushion 103, a right-angle groove 105 is opened on the top of the cushion 103, and a first slide groove 106 is symmetrically opened on one side of the cushion 103. A first abutment plate 107 and a second abutment plate 108 that conflict with the first screening box 303 and the second screening box 304 are fixedly connected to one side of the cushion 103.

A drainage pipe 110 is connected to the outer side of the water reservoir 102, and the first abutment plate 107 and the second abutment plate 108 are fixedly connected to the outer side of the water reservoir 102. 7. The top of the second abutment plate 108 is fixedly connected to an electromagnet 111. The first screening assembly 2 also includes a partition plate 210 fixedly connected to the top of the guide plate 201 and located between the two second vertical plates 203. One end of the second rotating shaft 205 is fixedly connected to the first spur gear 209. One side of the second vertical plate 203 is rotatably connected to the third rotating shaft 211. The side surface of the third rotating shaft 211 is fixedly connected to a second spur gear 212 that meshes with the first spur gear 209. The end of the third rotating shaft 211 is fixedly connected to a first sprocket 213. A plurality of through holes 214 are opened on the outer wall of the conveyor belt 207.

[0039] The operation process of this embodiment is as follows: initially, the second screening box 304 is in conflict with the electromagnet 111 on the second abutment plate 108 (at this time, the electromagnet 111 on the second abutment plate 108 is working, so that the electromagnet 111 adsorbs the second screening box 304), and at the same time, the second screening box 304 triggers the third switch 109 on the second abutment plate 108, and then the control box 104 controls the solenoid valve on the delivery pipe to work, so that the delivery pipe injects sewage into the first screening assembly 2;

[0040] The third sprocket 409 is driven to rotate by the motor 403, thereby driving the first sprocket 213 to rotate clockwise, so that the first sprocket 213 drives the second spur gear 212 to rotate clockwise through the third rotating shaft 211, and the second spur gear 212 engages to drive the first spur gear 209 to rotate counterclockwise, providing power for the counterclockwise rotation of the first spur gear 209.

[0041] For example 3, please refer to Figure 1-13, the third embodiment is improved on the basis of the first embodiment as follows: the second screening component 3 also includes two second slide grooves 308 opened on one side of the turntable 302 and arranged at 120 degrees; a first switch 305 and a second switch 306 matched with the first screening box 303 and the second screening box 304 are fixedly connected on one side of the turntable 302; a driven gear 307 is fixedly connected to the side of the rotating rod 301; a guide rod 309 is fixedly connected to the inside of the second slide groove 308; a slider 310 slidingly matched with the second slide groove 308 is slidably connected to the side of the guide rod 309; a return spring 311 sleeved on the guide rod 309 is fixedly connected between the slider 310 and the second slide groove 308; the two sliders 310 are fixedly matched with the first screening box 303 and the second screening box 304 respectively; a stripping component 4 is fixedly matched on the top of the cushion seat 103; the stripping component 4 includes a support column 401 fixedly connected to the top of the cushion seat 103, a mounting seat 402 is fixedly connected to the top of the support column 401, a motor 403 is fixedly connected to the top of the mounting seat 402, and a first transmission rod 404 is fixedly connected to the output end of the motor 403; the stripping assembly 4 also includes a horizontal plate 405 fixedly connected to one side of the two second vertical plates 203, the two horizontal plates 405 are rotatably matched with the first transmission rod 404, a roller 406 located between the two horizontal plates 405 is fixedly connected to the side surface of the first transmission rod 404, and a plurality of stripping plates 407 arranged in an alternating manner with the paddle plate 208 are fixedly connected to the outer wall of the roller 406; a second sprocket 408 is fixedly connected to the side surface of the first transmission rod 404, a first chain is meshed and transmitted between the second sprocket 408 and the first sprocket 213, and a third sprocket 409 is fixedly connected to the side surface of the first transmission rod 404.

[0042] The operation process of this embodiment is as follows: initially, the first screening box 303 is in contact with the tail end of the guide plate 201. As the fluff fibers inside the first screening box 303 increase, the weight of the first screening box 303 increases, thereby causing the first screening box 303 to move downward, causing the first screening box 303 to contact the first switch 305 downward, thereby further controlling the rotation of the turntable 302, causing the first screening box 303 to rotate to be in contact with the electromagnet 111 on the first abutment plate 107, further triggering the third switch 109 on the first abutment plate 107, causing the electromagnet 111 on the first abutment plate 107 to absorb the first screening box 303 (at this time, the second screening box 304 rotates to be in contact with the tail end of the guide plate 201);

[0043] By controlling the motor 403 to drive the first transmission rod 404 to rotate clockwise, the first transmission rod 404 drives the roller 406, the second sprocket 408 and the third sprocket 409 to rotate clockwise. The roller 406 rotates clockwise, which further drives the plurality of stripping plates 407 to rotate clockwise, so that the stripping plates 407 can remove the fabric residues adhering to the paddle plate 208, thereby ensuring the cleanliness of the paddle plate 208 and further improving the screening effect. The second sprocket 408 rotates clockwise, so that the second sprocket 408 drives the first sprocket 213 to rotate clockwise through the first chain, thereby providing power for the rotation of the first sprocket 213.
