Description

[0001] The present application relates to the field of textile wastewater treatment, in particular to a fiber filtering device in the process of textile wastewater discharge. BACKGROUND

[0002] The fiber pollutants in the textile industrial wastewater are the key factors causing the over-standard of water body suspended solids, which are easy to accumulate in the pipeline and equipment to cause blockage and increase the system operation pressure. The current mainstream technology adopts single-stage metal filter screen for physical interception, but the fiber, especially the hydrophobic synthetic fiber, will quickly block the mesh hole, causing the filter pressure difference to rise significantly in a short time. For example, the filter pressure of the water jet loom wastewater system rises by more than 35% after 2 hours of continuous operation, the treatment efficiency decreases by nearly half, frequent shutdown cleaning or replacement of the filter screen is required, which seriously restricts the production efficiency.

[0003] In addition, some manufacturers use chemical cleaning method to reduce fiber pollution, such as citric acid-hydrogen peroxide combination. Although this method can alleviate the blockage, the residual cleaning agent reacts with the pollutants to generate toxic by-products, which has the risk of secondary pollution and increases the treatment cost. In addition, the chemical cleaning method cannot effectively realize the recycling and utilization of the fiber, causing further waste of cost.

[0004] In recent years, the improved technology reduces fiber pollution by biological enzymatic method, which can degrade dye organic matter, but cannot decompose physical fibers, making it difficult to realize the coordinated treatment of pollutants. SUMMARY

[0026] Referring to Figure 2 、 Figure 4 A sealing plate 105 is fixedly installed at the bottom of the cylinder body 101, the sealing plate 105 can be sealingly installed in a sewage outlet 106, so that the sealing property of the side surface of the cylinder body 101 is maintained, and the sewage outlet 106 is formed in the bottom of the side surface of the cylinder body 101 along the length direction, when the fiber impurities in the inside of the cylinder body 101 accumulate to a certain degree, the sealing plate 105 is disassembled, and the fiber impurities in the inside of the cylinder body 101 are discharged outward.

[0027] Referring to Figure 4 、 Figure 5 Both ends of the inner surface of the cylinder body 101 are coaxially fixed with mounting rings 107, the mounting rings 107 are used for rotatingly mounting a filtering mechanism 200, and the two mounting rings 107 are arranged at both ends of an annular cavity formed by the filtering mechanism 200 and the cylinder body 101, so that after textile wastewater enters the inside of the cylinder body 101 from the water inlet 104, the wastewater flows in the annular cavity formed by the cylinder body 101 and the filtering mechanism 200, and in this process, the filtering and removal of fibers in the textile wastewater are completed, and the treated wastewater is discharged outward through the water outlet 103.

[0028] Referring to Figure 3 、 Figure 4 、 Figure 8 A driving mechanism 300 is installed in the inside of the filtering mechanism 200, the driving mechanism 300 is used for driving the forward and reverse rotation of the filtering mechanism 200 in cooperation with the filtering mechanism 200, when the filtering mechanism 200 rotates forward, the filtering of fibers in the wastewater is completed, when the filtering mechanism 200 rotates reversely, a cleaning mechanism 400 arranged on the side surface of the cylinder body 101 is used for cleaning and collecting the accumulated fiber impurities, and then the fiber impurities are discharged outward through the sewage outlet 106.

[0029] As a further explanation of the above embodiment, referring toFigure 6 、 Figure 7 、 Figure 8 、 Figure 9 The filtering mechanism 200 comprises a rotating drum 201 rotatably mounted on the inner surface of the mounting ring 107, and a through hole 202 with a regular polygonal cross section is coaxially arranged in the rotating drum 201, and a plurality of groups of guide holes 203 are arranged on the rotating drum 201, each group of guide holes 203 penetrates the side wall of the rotating drum 201 and communicates the outer surface of the rotating drum 201 with the through hole 202.

[0030] A fiber blocking needle 204 slidingly arranged in the guide hole 203 is sealingly arranged in each guide hole 203, the fiber blocking needle 204 is fixedly mounted on a sliding block 205, a guide groove 206 is arranged on the side surface of the sliding block 205, the guide groove 206 is in sliding cooperation with a guide rail 207, and the guide rail 207 is fixed on the side surface of the through hole 202.

[0031] A driving pin 208 is fixedly mounted on the end surface of the sliding block 205, the driving pin 208 cooperates with a driving mechanism 300 to drive the reciprocating movement of the sliding block 205 along the length direction of the guide rail 207, so as to drive the extension and retraction of the plurality of fiber blocking needles 204 in the guide holes 203 through the sliding block 205.

[0032] A plurality of limiting blocks 209 are uniformly fixed on one end of the rotating drum 201 in the circumferential direction, and the limiting blocks 209 are in the shape of a sector, and a sensor 210 is fixedly mounted on the side surface of one of the limiting blocks 209.

[0033] The guide rail 207 is a dovetail-shaped guide rail, and the cross-sectional shape of the guide groove 206 is dovetail-shaped, which cooperates with the cross-sectional shape of the guide rail 207, so that the guide rail 207 smoothly guides the sliding block 205, and facilitates the movement of the fiber blocking needle 204 in the guide hole 203.

[0034] The driving mechanism 300 comprises a first motor 301 fixedly mounted on the end cover 102, the output end of the first motor 301 penetrates the end cover 102 and is coaxially fixed with a first end of a transmission shaft 303 through a shaft coupling 302, driving plates 304 are coaxially fixed on both ends of the transmission shaft 303, the outer surface of the driving plate 304 away from the first motor 301 abuts against the inner surface of the limiting block 209, a plurality of long holes 305 are uniformly arranged on the driving plate 304, the long holes 305 are distributed along the radial direction of the driving plate 304, and the driving pins 208 are arranged in the long holes 305 and move along the long holes 305.

[0035] A plurality of driving blocks 306 are uniformly fixed on the outer circumferential surface of the driving plate 304 in the circumferential direction, each driving block 306 is arranged between two adjacent limiting blocks 209, the side surface of the driving block 306 can be overlapped with the side surface of the limiting block 209, and the driving block 306 can be overlapped with the sensor 210 and trigger a signal.

[0036] The number of the sliding block 205, the limiting block 209, the long hole 305 and the driving block 306 is equal to the number of the edges of the through hole 202, so that the same group of the blocking fiber needle 204 can be extended and retracted in the guide hole 203.

[0037] In the process of filtering the textile wastewater, the output end of the first motor 301 drives the transmission shaft 303 to rotate forward through the shaft coupling 302, so that the clockwise rotation of the long hole 305 in the driving plate 304 is taken as the forward rotation direction. Figure 8 At this time, the forward rotation of the transmission shaft 303 drives the synchronous rotation of the driving plate 304, and the cooperation between the long hole 305 and the driving pin 208 drives the driving pin 208 and the sliding block 205 to move away from the axis of the transmission shaft 303, so as to push the blocking fiber needle 204 to pass through the guide hole 203 and extend out of the outer surface of the rotating drum 201.

[0038] At the same time, when the long hole 305 drives the synchronous rotation of the driving block 306, the driving block 306 is overlapped with the side surface of one side of the limiting block 209, so as to drive the limiting block 209 and the rotating drum 201 to rotate, at this time, the rotating drum 201 drives the several blocking fiber needles 204 distributed along the circumference to rotate in the cylinder body 101, so as to wind the fibers mixed in the textile wastewater on the blocking fiber needle 204, reduce the free fibers in the wastewater, and complete the filtering and removal of the fibers in the wastewater.

[0039] When too many fiber impurities are wound on the blocking fiber needle 204, after the wastewater in the annular gap between the cylinder body 101 and the filtering mechanism 200 is exhausted through the water inlet 104, the first motor 301 reversely rotates to drive the synchronous reverse rotation of the transmission shaft 303 and the driving plate 304, at this time, due to the configuration relationship between the driving pin 208 and the long hole 305, the driving pin 208 moves to the position close to the axis of the long hole 305, so as to drive the several blocking fiber needles 204 to retract into the guide hole 203, and the fiber impurities wound on the blocking fiber needle 204 are blocked on the outer surface of the rotating drum 201.

[0040] At the same time, the long hole 305 drives the reverse rotation of the driving block 306, and the driving block 306 is overlapped with the side surface of the other side of the limiting block 209, so as to drive the reverse rotation of the limiting block 209 and the rotating drum 201.

[0041] At the same time, the driving block 306 is overlapped with the sensor 210 installed on the limiting block 209, and triggers the sensor 210, and the sensor 210 sends a signal to the cleaning mechanism 400, so that the cleaning mechanism 400 is started, and cooperates with the rotation of the rotating drum 201 to scrape and remove the fiber impurities on the outer surface of the rotating drum 201.

[0042] The fiber impurities removed from the outer surface of the rotating drum 201 are collected at the bottom of the inner side of the cylinder body 101. At this time, the sealing plate 105 at the bottom of the cylinder body 101 is disassembled, the residual fiber impurities in the cylinder body 101 are discharged, and after the sealing plate 105 is reassembled, the work of removing the fiber impurities from the textile wastewater can be continued.

[0043] As a further explanation of the above embodiment, see Figure 4 、 Figure 10 、 Figure 11 The removal mechanism 400 includes a mounting hole 401 provided on the side surface of the cylinder body 101, a sealing scraper 402 sealingly arranged in the mounting hole 401, the sealing scraper 402 being rotatably mounted in the mounting hole 401 by a mounting shaft 403, the mounting shaft 403 being coaxially fixed with a first gear 404, the first gear 404 being engaged with a second gear 405, the second gear 405 being coaxially fixed with the output end of a second motor 406, and the second motor 406 being fixedly mounted in a blind hole provided at the end of the cylinder body 101.

[0044] The sealing scraper 402 is provided with a plurality of water spraying channels 407, the water spraying channels 407 being in communication with a water delivery pipe 408, the water delivery pipe 408 being fixedly mounted on the outer side of the sealing scraper 402, and the water delivery pipe 408 being in communication with a high-pressure water pipe.

[0045] The second motor 406 is signal connected with the sensor 210. When the driving block 306 is overlapped with the sensor 210 and triggers the sensor 210, the second motor 406 is started, and drives the first gear 404 and the sealing scraper 402 to rotate around the axis of the mounting shaft 403 through the meshing relationship between the second gear 405 and the first gear 404, the rotating direction being clockwise in the figure, so that the bottom end of the sealing scraper 402 is overlapped with the outer surface of the rotating drum 201. Since the rotating drum 201 is in a rotating state at this time, the overlapping of the sealing scraper 402 with the outer surface of the rotating drum 201 is beneficial to quickly remove the fiber impurities on the surface of the rotating drum 201. Figure 10

[0046] At the same time, the high-pressure water pipe delivers water into the plurality of water spraying channels 407 through the water delivery pipe 408, and the outer surface of the rotating drum 201 is washed by the water spraying channels 407, so as to improve the cleaning rate of the outer surface of the rotating drum 201.

[0047] In addition, the fiber impurities after washing are beneficial to be concentrated at the bottom of the cylinder body 101, so as to be easily discharged from the sewage outlet 106.

As is apparent to one of ordinary skill in the art, many choices and modifications can be made to adapt the illustrated embodiments to various uses and conditions. The above description is therefore not to be taken in a limiting sense, and the scope of the present application is defined by the appended claims.
