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 methods for treating printing and dyeing wastewater, among which biological treatment is considered the most effective and environmentally friendly. In biological treatment, activated sludge, which contains a large number of complex microorganisms, is introduced into the wastewater. These complex microorganisms come into contact with the organic waste in the wastewater, degrading it.

[0003] However, the above method has some shortcomings. There are not only a large amount of organic matter such as fabric residues and lint fibers in textile printing and dyeing wastewater, but also harmful chemicals. The microorganisms in 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 sewage 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 the process of screening 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. The replacement process requires a long suspension of the lint fiber screening, 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

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 and screened separately, which increases the number of purification tanks used, thereby increasing the use cost. 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 clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0034] For example 1, please refer to Figure 1-13The present invention provides the following technical solutions: A textile printing and dyeing wastewater treatment system includes a support assembly 1; the support assembly 1 includes 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 with the top of the cushion 103; the first screening assembly 2 includes 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 includes 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 a conveying roller 206 is fixedly connected to the outer walls of the first rotating shaft 204 and the second rotating shaft 205. A conveyor belt 207 is transmitted between the two conveying rollers 206, and a plurality of dial plates 208 are evenly and fixedly connected to the outer wall of the conveyor belt 207; a second screening assembly 3 is rotatably engaged with one side of the cushion 103, and the second screening assembly 3 includes a rotating rod 301 rotatably connected to the cushion 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 straight gear 209 is controlled to rotate counterclockwise, so that the first straight gear 209 drives the conveying roller 206 to rotate counterclockwise through the second rotating shaft 205 (as shown in FIG. Figure 6 As shown), 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 just 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). As the conveyor belt 207 and the plurality of paddles 208 rotate counterclockwise, 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, thereby achieving the removal of impurities in the sewage, providing 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, thereby achieving the purification of the sewage.

[0036] 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 exceeds the set threshold. 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 the water flow stops flowing into the first screening component 2, the driven gear 307 is controlled to rotate, so that the driven gear 307 drives the turntable 302 to rotate through the rotating rod 301, so that the turntable 302 drives the first screening box 303 away from the guide plate 2. 01, synchronously causing the turntable 302 to drive the second screening box 304 to rotate in the direction close to the guide plate 201, so that the second screening box 304 is in contact with the tail end of the guide plate 201 (synchronously controlling the solenoid valve of the external delivery pipe to continue to inject sewage into the external delivery pipe), 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 in the direction away from the guide plate 201, and synchronously drives the turntable 302 to rotate in the direction close to the guide plate 201, so that the first screening box 303 is fitted with the tail end of the guide plate 201 (the solenoid valve of the external delivery pipe is synchronously controlled to allow the external delivery pipe to continue 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, which affects 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 as follows on the basis of the first embodiment, 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, 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 are fixedly connected to one side of the cushion 103 and are in conflict with the first screening box 303 and the second screening box 304, a third switch 109 is installed on the top of the first abutment plate 107 and the second abutment plate 108, a drain pipe 110 is connected to the outer side of the water reservoir 102, and the first abutment plate 10 7.

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 the first sprocket 213. A number 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 contacts the electromagnet 111 on the second abutment plate 108 (at this time, the electromagnet 111 on the second abutment plate 108 is activated, causing the electromagnet 111 to adsorb the second screening box 304). 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 operate, causing the delivery pipe to inject 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, so that the second spur gear 212 engages and drives the first spur gear 209 to rotate counterclockwise, providing power for the counterclockwise rotation of the first spur gear 209.

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

[0042] The operation process of this embodiment is as follows: initially, the first screening box 303 is in contact with the rear 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 downwardly abut the first switch 305, 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 adsorb the first screening box 303 (at this time, the second screening box 304 rotates to be in contact with the rear 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 stripping plates 407 to rotate clockwise, so that the stripping plates 407 remove the fabric residues adhering to the paddle plate 208, thereby ensuring the cleanliness of the paddle plate 208 and 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, providing power for the rotation of the first sprocket 213.
