Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile wastewater, in particular to a cloth fiber-containing wastewater pretreatment device and treatment equipment. BACKGROUND

[0002] At present, a large amount of textile wastewater is generated in textile production, and the textile wastewater contains many pollutants, such as dyeing agents. If the textile wastewater generated in production is directly discharged, it will increase the environmental pressure. Therefore, before the textile wastewater is discharged, the textile wastewater needs to be treated so that the various indexes in the textile wastewater can meet the discharge standard, thereby effectively avoiding the pollution of the discharged textile wastewater to the environment.

[0003] In the process of treating the textile wastewater, a pretreatment device is usually used to pretreat the textile wastewater, so as to effectively intercept the cloth, thread and other lint fiber impurities in the textile wastewater, so that the textile wastewater after the pretreatment device can enter the next process of wastewater treatment well.

[0004] However, since the cloth, thread and other lint fiber impurities in the textile wastewater are in irregular shapes, such as short strip shape, long strip shape, lint shape and the like, the long strip-shaped lint fiber impurities are easy to wrap around the filter holes when flowing with the textile wastewater, thereby causing serious blockage of the filter holes of the pretreatment device, and further increasing the difficulty of cleaning the filter holes. In this way, not only the cleaning efficiency is slow, but also the inside of the filter holes is not cleaned well, that is, there is a poor cleaning effect.

[0005] For example, a textile printing and dyeing wastewater pretreatment equipment is disclosed in patent CN 217430974 U, and specifically disclosed is that the textile printing and dyeing wastewater pretreatment equipment comprises a machine body, a filter screen fixed at the upper end in the machine body, a water tank movably connected at the lower end of the filter screen in the machine body, a rotating disc movably connected at the lower end of the machine body, a plurality of filter cylinders fixed at the upper end of the rotating disc, a plurality of filter holes provided on the outer side of the filter cylinders, a scraper provided in the filter cylinder and movable to scrape the filter cylinder, a plurality of floating balls provided on the outer side of the filter cylinder and movable to move the scraper, a notch provided at the lower end of the outer side of the machine body, a collection cylinder fixed at the lower end of the outer side of the machine body, a drain pipe fixed at the lower end of one side of the machine body, and a second motor fixed at the lower end of the machine body and capable of driving the rotating disc to rotate. Mainly through the cooperation of the first motor, the drive shaft, the lever, the cleaning plate, the collection box and the slag discharge port, the first motor drives the drive shaft, the lever and the cleaning plate to rotate. When the lever rotates, the intercepted impurities on the upper end of the filter screen can be hung and then thrown into the slag discharge port. The intercepted impurities are guided into the collection box for collection through the slag discharge port. Meanwhile, the cleaning plate rotates to clean the inner wall of the machine body, so as to prevent the intercepted impurities from being thrown on the inner wall of the machine body. As can be seen, CN 217430974 U only uses the lever to clean the impurities intercepted on the upper end of the filter screen, and does not clean the inside of the filter holes, so that the inside of the filter holes has a poor cleaning effect.

DETAILED DESCRIPTION

[0037] For the purposes of this disclosure, like reference numerals in the description and in the drawings will be understood to refer to like parts, steps and features. The following description is presented to enable any person skilled in the art to make and use the application. Descriptions of specific devices and applications are provided only as examples. Any such specific examples of components and applications are not intended to limit the scope of the present application in any way.

[0038] It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. It is also possible in the present application that steps can be executed in different sequence, where this is explicitly indicated or otherwise is apparent from this disclosure.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting. The use of the terms "and / or" includes any and all combinations of one or more of the associated listed items.

[0040] The application provides a cloth fiber-containing wastewater pretreatment device, which comprises a tank body, a filter plate, a folding cleaning assembly and a driving assembly. The tank body is provided with a cavity, and a sewage outlet is formed in the cavity. The filter plate is arranged in the cavity and is provided with a plurality of filter holes. The folding cleaning assembly comprises a folding plate and a plurality of cleaning nozzles. The folding plate is movably arranged on the side wall of the cavity and is formed with a channel. The channel is provided with a water inlet. Each cleaning nozzle is arranged on one side of the folding plate facing the filter plate. Each cleaning nozzle is in communication with the channel. Each cleaning nozzle is arranged in one-to-one correspondence with each filter hole and is adapted to each filter hole. A first cleaning layer is arranged on the outer peripheral wall of each cleaning nozzle. The driving assembly comprises a first driver and a second driver. The output end of the first driver is connected with the first end of the folding plate. The first driver is used for driving the folding cleaning assembly to approach or move away from the filter plate. The output end of the second driver is connected with the second end of the folding plate. The second driver is used for driving the folding plate to unfold or fold.

[0041] The cloth fiber-containing wastewater pretreatment device has the following advantages. The cleaning nozzles are arranged one by one in correspondence with the filter holes, and the cleaning nozzles are matched with the filter holes. The output end of the first driver is connected with the first end of the folding plate, so that the first driver can drive the plurality of cleaning nozzles on the folding plate to enter the filter holes of the filter plate. Each cleaning nozzle is arranged on the side of the folding plate facing the filter plate and is in communication with the channel. At this time, when the external water source flows into the channel from the water inlet of the channel and is sprayed from the plurality of cleaning nozzles, a relatively strong water pressure can be generated inside the filter hole, thereby playing a good backwashing effect on the blockage in the filter hole. The cleaning nozzles can flush out the blockage in the filter hole. In this way, each cleaning nozzle repeatedly flushes the corresponding filter hole, which can more comprehensively flush out the blockage in the filter hole. The blockage flushed out is discharged from the sewage outlet, so as to realize rapid and comprehensive cleaning of the inside of each filter hole without dead angles. That is, the cleaning efficiency is improved, and the cleaning depth of the inside of the filter hole is improved. Further, the first cleaning layer is arranged on the outer peripheral wall of each cleaning nozzle, so that the first driver can continuously drive the folding plate to move back and forth, so that the cleaning nozzle can move back and forth in the filter hole. The first cleaning layer of the cleaning nozzle can scrub off the lint fiber impurities on the inner wall of the filter hole and also play a certain cleaning effect on both sides of the filter plate. In this way, the cleaning depth of the inside of the filter hole is further improved to better ensure the effect of cleaning the inside of the filter hole without dead angles. In addition, the cleaning effect on both sides of the filter plate is good, so that the cleaning effect of the filter plate is improved. Further, the output end of the second driver is connected with the second end of the folding plate, so that the second driver can drive the folding plate to unfold or fold. The folding plate can be well folded in the cavity, so as to avoid affecting the flow of the textile wastewater due to the unfolded folding plate. That is, the cloth fiber-containing wastewater pretreatment device can dredge the filter holes of the filter plate according to the actual filter hole blockage during production, so as to avoid the phenomenon that the filter holes are seriously blocked to affect the pretreatment efficiency of the cloth fiber-containing wastewater, improve the pretreatment efficiency of the cloth fiber-containing wastewater, and reduce the difficulty of subsequent cleaning of the filter holes.

[0042] In order to better understand the technical solutions and beneficial effects of the present application, the present application will be further described in detail below in combination with specific embodiments.

[0043] Please refer to Figures 1 to 3The processing device of one embodiment (not shown in the figure) comprises the cloth fiber-containing wastewater pretreatment device 10, a secondary filtration device (not shown in the figure) and a biochemical treatment device (not shown in the figure), so that the cloth fiber-containing wastewater is initially filtered through the cloth fiber-containing wastewater pretreatment device 10 to effectively remove the lint fiber impurities in the cloth fiber-containing wastewater, then is further filtered through the secondary filtration device to more effectively remove the fine lint and impurities in the cloth fiber-containing wastewater, and finally is treated in the biochemical treatment device to make the cloth fiber-containing wastewater meet the discharge standard, thereby effectively avoiding the pollution of the discharged textile wastewater to the environment.

[0044] Please refer to Figures 1 to 3 The cloth fiber-containing wastewater pretreatment device 10 of one embodiment comprises a tank body 100, a filter plate 200, a folding cleaning assembly 300 and a driving assembly 400, the tank body 100 is provided with a cavity 110, a sewage outlet 111 is formed in the cavity 110, the filter plate 200 is arranged in the cavity 110, the filter plate 200 is provided with a plurality of filter holes 210, the folding cleaning assembly 300 comprises a folding plate 310 and a plurality of cleaning nozzles 320, the folding plate 310 is movably arranged on the side wall of the cavity 110, please refer to Figure 7 the folding plate 310 is provided with a channel 311, the channel 311 is provided with a water inlet, each of the cleaning nozzles 320 is arranged on the side of the folding plate 310 facing the filter plate 200, each of the cleaning nozzles 320 is in communication with the channel 311, each of the cleaning nozzles 320 is arranged in one-to-one correspondence with each of the filter holes 210, and each of the cleaning nozzles 320 is adapted to each of the filter holes 210, and each of the cleaning nozzles 320 is provided with a first cleaning layer 326 on the outer peripheral wall thereof; please refer to Figures 4 to 5 the driving assembly 400 comprises a first driver 410 and a second driver 420, the output end of the first driver 410 is connected with the first end of the folding plate 310, the first driver 410 is used to drive the folding cleaning assembly 300 to approach or move away from the filter plate 200, the output end of the second driver 420 is connected with the second end of the folding plate 310, and the second driver 420 is used to drive the folding plate 310 to unfold or fold.

[0045] It should be noted that, since the cloth fiber-containing wastewater contains cloth scraps, lint and relatively high fibers, and is mostly irregular and easy to shape, it is more likely to wrap the filter hole 210 during filtration, thereby causing the cleaning frequency to be relatively high. If the inner wall of the filter hole 210 has a dead cleaning angle, the side wall of the filter hole 210 has a protrusion, thereby making the long strip-shaped lint fibers in the cloth fiber-containing wastewater more likely to wrap around the protrusion, thereby causing the filter hole 210 to be blocked. Since the cloth fiber-containing wastewater is continuously flowing in the tank 100, the long strip-shaped lint fibers wrapped around the filter hole 210 are continuously swinging above the filter plate 200, thereby causing more long strip-shaped lint fibers and short strip-shaped lint fibers to be wrapped, thereby being able to wrap a mesh above the filter plate 200, thereby enabling the wrapped mesh to quickly wrap the short strip-shaped, long strip-shaped and lint-shaped lint fibers, thereby quickly causing the filter hole 210 to be more severely blocked. Therefore, it is particularly important to ensure that the inside of the filter hole 210 is cleaned without dead angles.

[0046] Therefore, in the present application, since each cleaning nozzle 320 is arranged one-to-one corresponding to each filter hole 210, and each cleaning nozzle 320 is adapted to each filter hole 210, and the output end of the first driver 410 is connected to the first end of the folding plate 310, the first driver 410 can drive the plurality of cleaning nozzles 320 on the folding plate 310 into the filter hole 210 of the filter plate 200. Each cleaning nozzle 320 is arranged on the side of the folding plate 310 facing the filter plate 200, and each cleaning nozzle 320 is in communication with the channel 311. At this time, when the external water source flows into the channel 311 from the water inlet of the channel 311 and is sprayed out from the plurality of cleaning nozzles 320, a strong water pressure can be generated inside the filter hole 210, thereby playing a good backwashing effect on the blockage in the filter hole 210, so that the cleaning nozzle 320 can flush the blockage in the filter hole 210 out. In this way, each cleaning nozzle 320 can repeatedly flush the corresponding filter hole 210, which can more comprehensively flush the blockage in the filter hole 210 out, and then discharge the flushed blockage out of the sewage discharge port 111, so as to realize rapid and comprehensive cleaning without dead angles inside each filter hole 210, that is, not only improve the cleaning efficiency, but also improve the cleaning depth of the inside of the filter hole 210.

[0047] Further, please refer to Figure 8Since the first cleaning layer 326 is arranged on the outer peripheral wall of each cleaning nozzle 320, the first driver 410 can continuously drive the folding plate 310 to move back and forth, so that the cleaning nozzle 320 can move back and forth in the filter hole 210, and the first cleaning layer 326 of the cleaning nozzle 320 can wipe off the lint impurities on the inner wall of the filter hole 210 and clean the two surfaces of the filter plate 200. In this way, the cleaning depth of the inside of the filter hole 210 is further improved, the effect of cleaning the inside of the filter hole 210 without dead angles is better ensured, and the two surfaces of the filter plate 200 are better cleaned, thereby improving the cleaning effect of the filter plate 200.

[0048] Further, referring to Figure 2 The above-mentioned cloth fiber-containing wastewater pretreatment device 10, since the output end of the second driver 420 is connected with the second end of the folding plate 310, the second driver 420 can drive the folding plate 310 to unfold or fold, so that the folding plate 310 can be well folded in the cavity 110, avoiding the unfolded folding plate 310 affecting the flow of the textile wastewater, that is, the cloth fiber-containing wastewater pretreatment device 10 can dredge the filter hole 210 of the filter plate 200 according to the actual filter hole 210 blockage during production, to avoid the filter hole 210 being seriously blocked to affect the pretreatment efficiency of the cloth fiber-containing wastewater, to improve the pretreatment efficiency of the cloth fiber-containing wastewater and reduce the difficulty of subsequent cleaning of the filter hole 210.

[0049] It should be further noted that when the cloth fiber-containing wastewater pretreatment device 10 is used to treat the cloth fiber-containing wastewater, the user can start the folding cleaning assembly 300 to dredge the filter hole 210 according to the actual filter hole 210 blockage. When dredging is needed, the second driver 420 can be started to unfold the folding plate 310, so that each cleaning nozzle 320 faces each filter hole 210, and then the first driver 410 is started to make each cleaning nozzle 320 shuttle back and forth in the corresponding filter hole 210, so that each cleaning nozzle 320 can better dredge the filter hole 210, to realize rapid pretreatment of the cloth fiber-containing wastewater.

[0050] Referring to Figure 1 , Figure 2In some other embodiments, the cavity 110 is provided with an inlet 112 above the cavity 110 to allow the fabric-fiber-containing wastewater to flow in from the inlet 112; in some other embodiments, the drain outlet 111 includes a first drain outlet 1111 and a second drain outlet 1112, and the second drain outlet 1112 is arranged at the bottom of the tank 100 to allow the fabric-fiber-containing wastewater to flow in from the inlet 112 above the cavity 110, pass through the filter holes 210 of the filter plate 200 under the action of gravity, and then be drained out of the second drain outlet at the bottom, thereby achieving the primary filtration of the fabric-fiber-containing wastewater. When the filter holes 210 are blocked, the entangled mesh is usually attached to the top of the filter plate 200, and the entangled mesh at the bottom of the filter plate 200 is less. Therefore, in some other embodiments, the folding cleaning assembly 300 is arranged below the filter plate 200, so that the water flow sprayed out of each cleaning nozzle 320 can be back-flushed from the bottom of the filter plate 200 to the top, thereby driving the less entangled mesh at the bottom of the filter plate 200 to be separated from the filter holes 210, to achieve the rapid separation of the entangled mesh from the filter holes 210.

[0051] It is worth mentioning that, since there is less entangled mesh at the bottom of the filter plate 200 and more entangled mesh at the top of the filter plate 200, and the entanglement of the entangled mesh at the top of the filter plate 200 is more solid than that at the bottom of the filter plate 200, if the folding cleaning assembly 300 is arranged above the filter plate 200, since the filter holes 210 are already blocked, the water flow sprayed out of each cleaning nozzle 320 will further increase the blocking of the filter holes 210 when back-flushed from the top of the filter plate 200 to the bottom, thereby causing the filter plate 200 to easily expand and bend. That is, when the folding cleaning assembly 300 is arranged above the filter plate 200, a larger water flow is required to back-flush the filter holes 210 to separate the entangled mesh from the filter holes 210, which not only reduces the cleaning efficiency of the filter holes 210, but also causes a large amount of water resources to be wasted, resulting in a higher cost, and also causes the filter plate 200 to easily expand and bend, affecting normal use. Therefore, the folding cleaning assembly 300 is arranged below the filter plate 200 in the present application, which can quickly and effectively separate the less entangled mesh at the bottom of the filter plate 200 from the filter holes 210, achieve the rapid separation of the entangled mesh from the filter holes 210, use less water resources, and avoid the deformation of the filter plate 200.

[0052] Please refer to Figure 1In some other embodiments, the drain port 111 comprises a first drain port 1111 and a second drain port 1112, the first drain port 1111 is arranged adjacent to the filter plate 200, and the second drain port 1112 is arranged at the bottom of the tank body 100 to realize the discharge of the blockage in the filter hole 210 after cleaning.

[0053] Referring to Figure 2 In some other embodiments, the first drain port 1111 is formed with an inclined discharge port to enable the blockage in the filter hole 210 after cleaning to better enter the first drain port 1111 to realize the rapid discharge of the blockage in the filter hole 210 after cleaning.

The second end of the folding main rod 313 is provided with a sliding block 3131, which is slidably disposed on the second lead screw 440, so that the second driver can drive the folding main rod 313 to unfold or retract, thereby realizing the unfolding or retraction of the folding plate 310. Of course, the second driver 420 driving the folding plate 310 to unfold or retract is not limited to the technical solutions mentioned in this embodiment, and can also be achieved by existing technologies, such as the second driver 420 being a cylinder. Furthermore, in one embodiment, the motor is provided with an acid and alkali resistant cover, which can effectively ensure the service life of the motor.

[0058] Please see Figure 7 In some other embodiments, the channel 311 includes a main channel 3111, a first sub-channel 3112, and a second sub-channel 3113. The main channel 3111 is disposed on the folding main rod 313 and has a water inlet. The first sub-channel 3112 is disposed on the first folding part 314, and the second sub-channel 3113 is disposed on the second folding part 315. The first sub-channel 3112 and the second sub-channel 3113 are respectively connected to the main channel 3111. Each cleaning nozzle 320 is divided into a first cleaning nozzle group 321, a second cleaning nozzle group 322, and a third cleaning nozzle group 323. The first cleaning nozzle group 321 is connected to the main channel 3111, the second cleaning nozzle group 322 is connected to the first sub-channel 3112, and the third cleaning nozzle group 323 is connected to the second sub-channel 3113, so as to realize the mutual communication between each cleaning nozzle 320 and the main channel 3111, the first sub-channel 3112, and the second sub-channel 3113. Furthermore, in one of its instances, the channel 311 is formed by foldable water pipes.

[0059] In one example, the folding main rod 313 protrudes from the first folding portion 314 and the second folding portion 315, so that the first cleaning nozzle group 321, the second cleaning nozzle group 322 and the third cleaning nozzle group 323 can be on the folding plate 310, thereby enabling each cleaning nozzle 320 to spray water at different levels on the folding plate 310, so as to effectively avoid the phenomenon that the filter plate 200 is easily deformed under high water flow.

[0060] Please see Figure 4 andFigure 5 In some other embodiments, the first folding portion 314 comprises a plurality of first supporting members 3141 and a plurality of first folding members 3142, each of the first supporting members 3141 is arranged on the first side wall of the folding main rod 313 at intervals, and each adjacent first supporting member 3141 is arranged with a first folding member 3142 therebetween to achieve the folding or folding up of the first folding portion 314. Similarly, in some other embodiments, the second folding portion 315 comprises a plurality of second supporting members 3151 and a plurality of second folding members 3152, each of the second supporting members 3151 is arranged on the second side wall of the folding main rod 313 at intervals, and each adjacent second supporting member 3151 is arranged with a second folding member 3152 therebetween to achieve the folding or folding up of the second folding portion 315.

[0061] In some other embodiments, the first supporting members 3141 are metal members, and the first folding members 3142 are foldable plastic members with better hardness, so that the plurality of first supporting members 3141 can provide better support for the plurality of first folding members 3142 when unfolded, so that each cleaning nozzle 320 can reliably and smoothly spray water into each filter hole 210.

[0062] Similarly, in some other embodiments, the second supporting members 3151 are metal members, and the second folding members 3152 are foldable plastic members with better hardness, so that the plurality of second supporting members 3151 can provide better support for the plurality of second folding members 3152 when unfolded, so that each cleaning nozzle 320 can reliably and smoothly spray water into each filter hole 210.

[0063] Further, in some other embodiments, the metal members are corrosion-resistant stainless steel, which not only ensures that the first supporting members 3141 and the second supporting members 3151 have better hardness, but also improves the service life of the first supporting members 3141 and the second supporting members 3151.

[0064] Further, in some other embodiments, the plastic members are corrosion-resistant foldable silica gel members to ensure that the water sprayed by the cleaning nozzles 320 can be accurately sprayed into the filter holes 210, so that the water sprayed by the cleaning nozzles 320 can play a good backwashing effect on the blockages in the filter holes 210. Further, the hardness of the silica gel members is 40 degrees to 60 degrees, so that the silica gel members have better hardness and a certain softness.

[0065] It should be noted that, since the first support 3141, the second support 3151, the first folding piece 3142 and the second folding piece 3152 are respectively made of materials with two different material hardness, that is, a structure combining soft and hard materials, so that the second lead screw 440, the plurality of first supports 3141 and the plurality of second supports 3151 can provide a better support framework for the folding main rod 313, the plurality of first folding pieces 3142 and the plurality of second folding pieces 3152, to ensure that the cleaning nozzle 320 can better spray water flow into the inside of the filter hole 210, and cooperate with the first folding piece 3142 and the second folding piece 3152 with a hardness of 40 degrees to 60 degrees of the silica gel piece to be used at the same time, so that each cleaning nozzle 320 provided on the first folding piece 3142 and the second folding piece 3152 will have a small range of swing during the process of spraying water flow, thereby causing the first folding piece 3142 and the second folding piece 3152 to swing, and then causing the water in the first sub-channel 3112 provided on the first folding piece 3142 and the second sub-channel 3113 provided on the second folding piece 3152 to also fluctuate, thereby causing the water flow finally flowing into the cleaning nozzle 320 to have a certain fluctuation difference, so that the water pressure in the cleaning nozzle 320 is high at one time and low at another time, thereby enabling the cleaning nozzle 320 to better perform backwashing cleaning on the blockage in the filter hole 210, that is, a lower water pressure enables the water flow sprayed out of the cleaning nozzle 320 to form a water flow with a smaller amplitude in the filter hole 210, while a higher water pressure enables the water flow sprayed out of the cleaning nozzle 320 to form a water flow with a larger amplitude in the filter hole 210, so that the cleaning nozzle 320 can form a water flow with a certain vibration amplitude in the filter hole 210 when cleaning the blockage in the filter hole 210, enabling the water flow entering the filter hole 210 to form a vibration fluctuation in the filter hole 210, so that the smaller water flow formed in the filter hole 210 when the water pressure is lower can avoid the phenomenon that the filter plate 200 is easily deformed when being washed by a higher water pressure for a long time, thereby ensuring that the filter plate 200 can still maintain a better structure after being used for a long time, thereby prolonging the service life of the filter plate 200, and at the same time, cooperating with the use of the cleaning nozzle 320 when the water pressure is higher, enabling the cleaning nozzle 320 to form a water flow with a larger vibration amplitude in the filter hole 210, so as to better and faster wash out the entangled mesh in the filter hole 210, that is, under the condition of ensuring a fast cleaning effect, the phenomenon that the filter plate 200 is easily deformed is also effectively ensured, thereby prolonging the service life of the filter plate 200.

[0066] It should be noted that, due to the combination of soft and hard structure formed by the first support 3141, the second support 3151, the first folding part 3142 and the second folding part 3152, the second cleaning nozzle group 322 on the first folding part 3142 can swing, while the second cleaning nozzle group 322 on the first support 3141 does not swing, the third cleaning nozzle group 323 on the second folding part 3152 can swing, while the third cleaning nozzle group 323 on the second support 3151 does not swing, so that the water flow sprayed by the second cleaning nozzle group 322 and the third cleaning nozzle group 323 to each filter hole 210 has different amplitude fluctuations, and the water flow sprayed by the second cleaning nozzle group 322 and the third cleaning nozzle group 323 has different washing forces on the filter plate 200, so as to effectively avoid the phenomenon that the high water pressure causes the filter plate 200 to be deformed, thereby ensuring that the filter plate 200 has a good structure, and further prolonging the service life of the filter plate 200.

[0067] Please refer to Figure 7 In other embodiments, the cleaning nozzle 320 comprises a folding body 324 and a nozzle 325, and the nozzle 325 is in communication with the channel 311 through the folding body 324, so that the folding body 324 can be well folded to ensure that the cloth fiber-containing wastewater pretreatment device 10 can normally operate. Further, in other embodiments, the nozzle 325 is exposed on the folding plate 310 after being folded, so as to avoid scratching the folding plate 310 during folding.

[0068] In other embodiments, the cross section of the nozzle 325 is inverted funnel-shaped, so as to ensure that the water flow in the nozzle 325 has good spraying force, so as to ensure that the water flow sprayed by the nozzle 325 can better wash the entangled mesh in the filter hole 210, so as to ensure that the water flow can better wash the entangled mesh in the filter hole 210.

[0069] Please refer to Figure 8 In other embodiments, the folding body 324 forms a wave-shaped buffer channel 311, the nozzle 325 forms an inverted funnel-shaped inner nozzle 3251 and a trapezoidal outer nozzle 3252 which are in communication with each other, and the trapezoidal outer nozzle 3252 is in communication with the wave-shaped buffer channel 3241 through the inverted funnel-shaped inner nozzle 3251.

[0070] It should be noted that, due to the action force of the jet flow on the cleaning nozzle 320, the cleaning nozzle 320 will swing on the first folding part 314 and the second folding part 315, that is, the force of the swing of the cleaning nozzle 320 is mainly the water pressure generated by the water flow inside the nozzle 325, and the water pressure inside the nozzle 325 is mainly composed of the wave-shaped buffer channel 311 of the folding body 324, the inverted funnel-shaped inner nozzle 3251 and the trapezoidal outer nozzle 3252 in the nozzle 325, so that the water flow passing through the wave-shaped buffer channel 311 will fluctuate, thereby enabling the folding body 324 to swing slightly, and further enabling the nozzle 325 to swing when jetting the water flow, thereby increasing the jetting range around the side wall of the filter hole 210, that is, the filter plate 200 can be cleaned to a certain extent, and at the same time, the water flow entering the inverted funnel-shaped inner nozzle 3251 can be ensured to have fluctuation difference, so as to ensure that the water flow jetted out of the trapezoidal outer nozzle 3252 will appear high and low at different times, and at the same time, the use of the inverted funnel-shaped inner nozzle 3251 and the trapezoidal outer nozzle 3252 enables the cleaning nozzle 320 to swing regularly when jetting the water flow to the blockage in the filter hole 210, thereby driving the first folding part 314 and the second folding part 315 to swing, and further ensuring that the water flow in the first sub-channel 3112 arranged in the first folding part 314 and the water flow in the second sub-channel 3113 arranged in the second folding part 315 can better fluctuate, so as to ensure that the water flow flowing into the wave-shaped buffer channel 3241 can better fluctuate in the wave-shaped buffer channel 3241, so that the water flow is continuously circulated, thereby ensuring that the cleaning nozzle 320 can swing regularly on the first folding part 314 and the second folding part 315, which can clean the filter plate 200 to a certain extent on the one hand, and can quickly flush out the blockage in the filter hole 210 on the other hand, thereby improving the cleaning efficiency; on the other hand, it also avoids the phenomenon that the filter plate 200 is easily deformed during the cleaning process, thereby ensuring the service life of the filter plate 200.

[0071] Please refer to Figure 8 In some other embodiments, the cleaning nozzle 320 further comprises a first filter screen 327 arranged on the outside of the trapezoidal outer nozzle 3252, so as to effectively block the blockage in the splashing liquid generated when the nozzle 325 jets the water flow to the filter hole 210 from entering the trapezoidal outer nozzle 3252 to cause the trapezoidal outer nozzle 3252 to be blocked.

[0072] Please refer to Figure 8 In one embodiment, the cleaning nozzle 320 further comprises a second filter screen 328, and the trapezoidal outer nozzle 3252 is connected in communication with the inverted funnel-shaped inner nozzle 3251 through the second filter screen, so as to effectively avoid the blockage in the splashing liquid from entering the wave-shaped buffer channel 3241.

[0073] Further, please refer to Figure 8 In one embodiment, the cleaning nozzle 320 further comprises a third filter screen 329, and the inverted funnel-shaped inner nozzle 3251 is connected to the wavy buffer channel 3241 through the third filter screen, so as to further prevent the blockage from entering the buffer channel 311, and to ensure that the nozzle 325 can remain unblocked after long-term use.

[0074] Please refer to Figure 8 In one embodiment, the first cleaning layer 326 comprises a first cleaning sub-layer 3261 and a second cleaning sub-layer 3262, the first cleaning sub-layer 3261 is arranged around the outer peripheral wall of the folding body 324, and the second cleaning sub-layer 3262 is arranged on the outer peripheral wall of the nozzle 325, so that when the cleaning nozzle 320 moves back and forth under the driving of the first driver 410, the first cleaning sub-layer 3261 and the second cleaning sub-layer 3262 can clean the inner wall of the filter hole 210 in all directions without dead angle, thereby improving the cleaning effect of the inner wall of the filter hole 210.

[0075] In other embodiments, the first cleaning layer 326 is a brush, and because the brush has a good deformation structure and cleaning effect, the cleaning nozzle 320 can smoothly move back and forth in the filter hole 210, thereby cleaning the inner wall of the filter hole 210. Further, in one embodiment, the brush is a soft brush, so that the soft brush can more smoothly brush the inner wall of the filter hole 210, thereby improving the cleaning effect and efficiency of the inner wall of the filter hole 210.

[0076] It should be noted that because the nozzle 325 is inverted funnel-shaped, the nozzle 325 forms a detour, so that when the cleaning nozzle 320 moves back and forth in the filter hole 210, the blockage in the filter hole 210 can be easily hooked out, thereby achieving rapid cleaning of the filter hole 210.

[0077] Please refer to Figure 8In some other embodiments, the second cleaning sub-layer 3262 is formed with bent-beard-shaped cleaning portions 3262a, and the cleaning portions 3262a are arranged adjacent to the outer periphery wall of the inverted-trapezoidal outer nozzle 3252, so that the bent-beard-shaped cleaning portions 3262a can form larger meanders on the outer periphery wall of the inverted-trapezoidal outer nozzle 3252, on one hand, so that the second cleaning sub-layer 3262 can be deformed better, so that the cleaning nozzle 320 can be smoothly back and forth wiped in the filter hole 210, and at the same time, the meanders can carry out more blockages in the filter hole 210, so as to improve the cleaning efficiency of the filter hole 210, on the other hand, when the nozzle 325 passes through the filter hole 210, the bent-beard-shaped cleaning portions 3262a can be exposed on the other side of the filter plate 200, so that the bent-beard-shaped cleaning portions 3262a can play a good cleaning role on the other side of the filter plate 200 when the cleaning nozzle 325 is back and forth wiped in the filter hole 210, thereby improving the cleaning effect of the filter plate 200. Further, in one of the embodiments, the number of the bent-beard-shaped cleaning portions 3262a is multiple, and the multiple bent-beard-shaped cleaning portions 3262a are arranged around the outer periphery wall of the inverted-trapezoidal outer nozzle 3252, so that the multiple bent-beard-shaped cleaning portions 3262a can clean the inside of the filter hole 210 and the other side of the filter plate 200 more completely, thereby improving the cleaning effect of the filter plate 200, that is, completely and thoroughly.

[0078] In some other embodiments, the folding plate 310 is provided with a through hole, so that the through hole can discharge the waste liquid of the filter hole 210 backwashed on the folding plate 310.

[0079] Please refer to Figure 7 In some other embodiments, the outer side wall of the folding plate 310 is provided with a second cleaning layer 316, so that the second cleaning layer 316 can play a cleaning role on the inner wall of the tank 100 when the folding plate 310 is unfolded. Further, the second cleaning layer 316 is arranged on the outer side wall of the folding plate 310, so as to ensure that the second cleaning layer 316 can play a comprehensive cleaning role on the side wall of the tank 100. Further, the second cleaning layer 316 is a sponge layer.

[0080] In some other embodiments, the folding cleaning assembly 300 is arranged at the bottom of the tank 100. It can be understood that, by arranging the folding cleaning assembly 300 at the bottom of the tank 100, the first driver 410 can drive the folding cleaning assembly 300 to move back and forth between the bottom of the tank 100 and the filter plate 200, so that the second cleaning layer 316 of the folding plate 310 can play a cleaning role on the side wall between the bottom of the tank 100 and the filter plate 200.

[0081] In some other embodiments, the length of the cleaning nozzle 320 is greater than the depth of the filter hole 210, so that the cleaning nozzle 320 can be exposed on the other side of the filter plate 200 when passing through the filter hole 210, so that the cleaning nozzle 320 can clean the sidewall between the top of the tank 100 and the filter plate 200, thereby ensuring a more comprehensive cleaning of the sidewall of the tank 100.

[0082] In one embodiment, the cloth-containing wastewater pretreatment device 10 further comprises an automatic water adding assembly for adding water flow to the water inlet. Further, in one embodiment, the automatic water adding assembly is provided with a high-pressure water pump to ensure that the water flow entering the channel 311 has good water pressure.

[0083] Compared with the prior art, the present application has at least the following advantages:

[0084] 1. In the aforementioned pretreatment device 10 for wastewater containing textile fibers, each cleaning nozzle 320 is correspondingly arranged with each filter hole 210, and each cleaning nozzle 320 is adapted to each filter hole 210. Furthermore, the output end of the first driver 410 is connected to the first end of the folded plate 310, enabling the first driver 410 to drive multiple cleaning nozzles 320 on the folded plate 310 into the filter holes 210 of the filter plate 200. Each cleaning nozzle 320 is located on the side of the folded plate 310 facing the filter plate 200, and each cleaning nozzle 320 is connected to the channel 311. At this time, when external water flows into the channel 311 from the inlet, and from... Multiple cleaning nozzles 320 spray water, generating strong water pressure inside the filter holes 210. This effectively backwashes the blockages inside the filter holes 210, allowing the cleaning nozzles 320 to flush them out. The cleaning nozzles 320 continuously and repeatedly flush the corresponding filter holes 210, thoroughly removing the blockages. The cleaned blockages are then discharged through the drain port 111, achieving rapid and comprehensive cleaning of each filter hole 210 without any blind spots. This not only improves cleaning efficiency but also increases the cleaning depth inside the filter holes 210. Furthermore, since each cleaning nozzle 320 has a first cleaning layer 326 on its outer peripheral wall, the first driver 410 can continuously drive the folding plate 310 to move back and forth, thereby enabling the cleaning nozzle 320 to move back and forth inside the filter hole 210. This allows the first cleaning layer 326 of the cleaning nozzle 320 to scrub away the lint and fiber impurities on the inner wall of the filter hole 210, while also cleaning both sides of the filter plate 200. In this way, not only is the cleaning depth inside the filter hole 210 further improved to better ensure the cleaning effect of the filter hole 210 without dead corners, but it also has a better cleaning effect on both sides of the filter plate 200, thereby improving the cleaning effect of the filter plate 200.

[0085] 2. In the above-mentioned pretreatment device 10 for textile fiber-containing wastewater, since the output end of the second driver 420 is connected to the second end of the folding plate 310, the second driver 420 can drive the folding plate 310 to unfold or retract, so that the folding plate 310 can be well retracted in the cavity 110, avoiding the unfolded folding plate 310 from affecting the flow of textile wastewater. This allows the pretreatment device 10 for textile fiber-containing wastewater to clear the filter holes 210 of the filter plate 200 according to the actual blockage of the filter holes 210 during operation, so as to avoid serious blockage of the filter holes 210 affecting the pretreatment efficiency of textile fiber-containing wastewater, thereby improving the pretreatment efficiency of textile fiber-containing wastewater and reducing the difficulty of subsequent cleaning of the filter holes 210.

[0086] The above embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as the restriction of the patent scope of the present application. It should be pointed out that, for ordinary skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, which all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
