Description

Technical Field

[0001] This invention relates to the field of textile dyeing wastewater recycling technology, specifically to a textile dyeing wastewater recycling and utilization device. Background Technology

[0002] Textile dyeing and printing wastewater is a type of industrial wastewater with a large discharge volume and complex composition in the textile industry. It mainly comes from processes such as desizing, scouring, bleaching, dyeing, printing, and finishing in the dyeing and printing process. Textile dyeing and printing wastewater is an industrial wastewater generated in the textile dyeing and printing production process. It is characterized by large water volume, complex water quality, high color, high organic content, and unstable composition. If it is discharged directly without effective treatment, it will cause serious environmental pollution. It can be recycled and reused through technologies such as membrane osmosis and ultrafiltration. However, the recycling process faces many problems in terms of technology, economy, operation and management.

[0003] In the textile printing and dyeing process, aqueous solutions are used as a medium for production processes such as desizing, scouring, bleaching, dyeing, printing, and finishing. This process generates a large amount of water that is discharged. If the wastewater is directly treated, it will waste water resources and cannot be recycled for other uses in the textile process. Therefore, different recycling devices are needed for treatment. However, existing textile printing and dyeing wastewater recycling devices require frequent cleaning and maintenance, which is inconvenient. Furthermore, single devices have reduced efficiency when treating wastewater and cannot be combined to adjust the filtration effect according to the needs of the printing and dyeing process. Based on this, a textile printing and dyeing wastewater recycling device is proposed. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When using the device, the operator places the filter element assembly inside the main curved coil and installs the cleaning mechanism assembly on the top of the main curved coil, thereby fixing and limiting the filter element assembly. The inlet pipe and outlet pipe are connected to the wastewater inlet and outlet respectively. Then, the wastewater enters the main curved coil. At this time, the water is pressurized by the booster pump and flows inside the main curved coil under the limitation of the spiral auger plate. The sedimentable impurities in the wastewater settle at the bottom of the bend of the main curved coil, and the slag discharge mechanism provides a guide position for the impurities. Then, the water flows through the flow-limiting cone ring. The flow is guided into the inner side of the hollow tube by the support ring, and then guided through the hollow tube to the inner side of the ultrafiltration filter element and the sparse metal mesh cylinder. The sparse metal mesh cylinder intercepts the flocculent fibers, and then the wastewater is filtered through the ultrafiltration filter element. Next, the water flows through the outer side of the ultrafiltration filter element and the drainage hole, and is guided through the bend of the main curved coil. After being filtered through multiple filter element components, it is pumped by a pressure pump and discharged through the drainage pipe. This multi-stage filtration process increases the filtration efficiency. Furthermore, multiple curved coil mechanisms and the second treatment mechanism can be connected in parallel to filter according to the flow rate of the wastewater treatment, further increasing the filtration efficiency.

[0016] 2. This solution utilizes the S-shaped and U-shaped main curved coil and the curved shape of the straight pipe to facilitate the installation of the filter element assembly, the deposition of impurities, and cleaning. Furthermore, the multi-circulation curved pipe design allows for step-by-step filtration of wastewater. Therefore, as needed, the filter element assembly can be replaced with different filter pore sizes to achieve a step-by-step filtration effect and enable circulating filtration. This allows for adjustments to the filtration status according to different processes in the dyeing and printing process, facilitating filtration in multiple processes and enhancing the overall performance of the structure.

[0017] 3. When sediment needs to be cleaned, the deposits will accumulate at the bottom of the main curved coil after the valve is opened. The deposits will gradually accumulate inside the slag discharge pipe. With the sealing effect of the threaded sealing cap, the deposited impurities will accumulate inside the slag discharge pipe without leakage. They will then enter the inner side of the filter cartridge through the rubber guide cone ring. The valve will be closed, and the threaded sealing cap will be rotated to release the blockage of the slag discharge pipe. At this time, the water will be discharged from the gap between the threaded sealing cap and the slag discharge pipe, while the impurities will be carried out from the bottom of the filter screen of the filter cartridge. After cleaning, the filter cartridge will be refilled, and the valve will be opened to continue the next cycle. This facilitates cleaning and maintenance, reduces the labor intensity of the operators, and increases the service effectiveness of the structure. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-11This invention provides a technical solution: a textile dyeing and printing wastewater recycling device, comprising a base 1, a bending coil mechanism 5, a second processing mechanism 12, and a filter element assembly 15. The bending coil mechanism 5 includes a main bending coil 501, a support rod frame 6 fixedly sleeved on the outer side of the main bending coil 501, a shock absorber 7 fixedly installed at the bottom end of the support rod frame 6, a slag discharge mechanism 8 connected to the bottom end of the U-shaped tube of the main bending coil 501, a cleaning mechanism 10 connected to the top of the main bending coil 501, and a spiral auger plate 503 fixedly installed inside the bottom end of the main bending coil 501. A support ring 504 is fixedly installed inside the coil 501. Two sealing ring grooves 505 are opened at the top of the support ring 504. A flow-limiting cone ring 507 is fixedly installed at the bottom of the support ring 504. A hollow tube 502 is fixedly sleeved on the inner side of the support ring 504. Several water-permeable holes 506 are opened inside the hollow tube 502. A flow guide groove 508 is opened on the inner side of the support ring 504. Several flow guide holes 509 are opened at the bottom of the hollow tube 502. One end of the main bending coil 501 is connected to a corrugated pipe 402. The other end of the main bending coil 501 is connected to a pump 11.

[0032] The filter element assembly 15 includes an ultrafiltration filter element 1502. A top support plate 1501 is fixedly installed on the top of the ultrafiltration filter element 1502. Several drainage holes 1503 are opened on the outer side of the top support plate 1501. A bottom ring plate 1504 is fixedly installed on the bottom of the ultrafiltration filter element 1502. Two sealing rings 1505 are fixedly installed on the bottom of the bottom ring plate 1504. A sparse metal mesh cylinder 1506 is movably sleeved on the inner side of the ultrafiltration filter element 1502.

[0033] The working principle of the above technical solution is as follows: During use, the operator places the filter element assembly 15 inside the main bending coil 501 and installs the cleaning mechanism 10 assembly on top of the main bending coil 501, thereby fixing and limiting the filter element assembly 15. The inlet pipe 2 and the outlet pipe 13 are connected to the wastewater inlet and outlet ends, respectively. Then, the wastewater enters the main bending coil 501. At this time, the water is pressurized by the booster pump 4 and flows inside the main bending coil 501 under the limitation of the spiral auger plate 503. The sedimentable impurities in the wastewater settle at the bottom of the bend of the main bending coil 501, and the slag discharge mechanism 8 provides a guide position for the impurities. Then, the water flows into the main bending coil 501 through the flow limiting cone ring 507 and the support ring 504. The wastewater flows through the inner side of the hollow tube 502 and is guided to the inner side of the ultrafiltration filter element 1502 and the sparse metal mesh cylinder 1506. The sparse metal mesh cylinder 1506 intercepts the flocculent fibers, and then the wastewater is filtered through the ultrafiltration filter element 1502. The water then flows through the outer side of the ultrafiltration filter element 1502 and the drainage hole 1503, and is guided by the bend of the main curved coil 501. After being filtered by multiple filter element assemblies 15, the wastewater is pumped by the pump 11 and discharged through the drainage pipe 13. This multi-stage filtration process increases the filtration efficiency. Furthermore, the multiple curved coil mechanisms 5 and the second treatment mechanism 12 can be connected in parallel to filter according to the flow rate of the wastewater treatment, further increasing the filtration efficiency.

[0034] In another implementation scheme, such as Figures 1-5 As shown, the support rods 6 are linearly and evenly distributed on the outside of the bending coil mechanism 5, and the shock absorbers 7 are linearly and symmetrically distributed on the top of the base 1. The bottom end of the shock absorbers 7 is fixedly installed on the top of the base 1.

[0035] The support rod 6 provides support for the main bending coil 501, while the shock absorber 7 provides a bottom buffer for the support rod 6 and the bending coil mechanism 5. During operation, if there are too many impurities in the dyeing process, they may cause internal accumulation and blockage. At this time, a vibrating hammer or vibrating motor is used to apply vibration to the main bending coil 501, and the power of the booster pump 4 and the pump 11 is reduced. At the same time, the water flow rate and water pressure inside the main bending coil 501 are reduced. Under the action of vibration and gravity, the impurities are deposited at the U-shaped bottom end of the main bending coil 501, and the slag discharge mechanism 8 is opened to discharge them, which is convenient for cleaning maintenance and maintenance without disassembly.

[0036] In another implementation scheme, such as Figures 1-11As shown, the main bending coil 501 has a continuous S-shaped bending pipe structure, which is composed of multiple U-shaped bending sections connected in sequence. Each U-shaped bending section is connected by a straight pipe section, and the bending point is a rounded transition. The pipe ends are provided with connection ports. The spiral auger plate 503 is located at the U-shaped bend of the main bending coil 501, and the support ring 504 and the hollow pipe 502 are located at the straight pipe of the main bending coil 501.

[0037] The S-shaped, U-shaped, and straight-tube curved shapes of the main curved coil 501 facilitate the installation of the filter element assembly 15, the deposition of impurities, and cleaning. Furthermore, the multi-circulation curved tube design allows for step-by-step filtration of wastewater. Therefore, the filter element assembly 15 can be designed and replaced with different filter pore sizes as needed, achieving a step-by-step filtration effect and enabling circulating filtration. Additionally, the installation of the filter element assembly 15 and the main curved coil 501 can be changed to a multi-layer filter stack, allowing for adjustments to the filtration operation state according to different processes in the dyeing and printing process. This facilitates filtration in multiple processes, enhancing the overall effectiveness of the structure.

[0038] In another implementation scheme, such as Figures 1-11 As shown, the permeable holes 506 are evenly distributed in a circular linear pattern inside the hollow tube 502, and the guide holes 509 are evenly distributed in a circular pattern at the bottom end of the hollow tube 502. The positions of the guide holes 509 correspond to the positions of the guide grooves 508. The cleaning mechanism 10 includes a cleaning tube 1001, the bottom end of which is connected to the bend at the top of the main bending coil 501. The internal dimensions of the bottom end of the cleaning tube 1001 are adapted to the dimensions of the main bending coil 501. A top sealing cap 1004 is movably sleeved on the top of the cleaning tube 1001, and a sealing ring 1007 is fixedly installed at the bottom of the top sealing cap 1004. The dimensions of the sealing ring 1007 are adapted to the dimensions of the cleaning tube 1001. The outer surface of the top end of the cleaning tube 1001 is... A flange ring 1005 is fixedly fitted on the side. The top sealing cover 1004 and the flange ring 1005 are fixedly connected by bolts. A connecting rod 1002 is fixedly installed at the bottom of the top sealing cover 1004. A hollow ring plate 1006 is fixedly installed at the bottom end of the connecting rod 1002. The specifications and dimensions of the hollow ring plate 1006 are adapted to the specifications and dimensions of the main bending coil 501. The bottom of the hollow ring plate 1006 is in contact with the top of the hollow tube 502. The top of the hollow tube 502 is sealed. A guide arc 1003 is fixedly fitted on the outside of the connecting rod 1002. The outside of the guide arc 1003 is in sliding contact with the inner wall of the cleaning tube 1001. The specifications and dimensions of the guide arc 1003 are adapted to the specifications and dimensions of the bend at the top of the main bending coil 501.

[0039] When wastewater flows into the main curved coil 501, the larger impurities in the water flow are separated from the water flow by the spiral separation of the spiral auger plate 503. The larger impurities are then deposited at the bottom of the bend of the main curved coil 501 by the spiral guidance of the spiral auger plate 503, and gradually deposited inside the slag discharge mechanism 8. Then, the water flow enters the hollow tube 502 through the flow limiting cone ring 507. A portion of the water flow is guided to the outside of the hollow tube 502 by the guide hole 509 and the guide groove 508. At this time, most of the wastewater enters the ultrafiltration system under the guidance of the hollow tube 502 and the water permeable hole 506. The inner side of the filter element 1502 is filtered by a sparse metal mesh cylinder 1506, which intercepts light impurities such as fibers. After filtration by the ultrafiltration filter element 1502, the water flows to the outer side of the ultrafiltration filter element 1502, and is guided through the drain hole 1503 and through the hollow ring plate 1006. Under the guidance of the guide arc 1003, it enters the bend at the top of the main curved coil 501 and continues to the next filtration cycle. The overall filtration effect is perfect. If the sparse metal mesh cylinder 1506 and the ultrafiltration filter element 1502 become clogged during filtration, the booster pump 4 and the pump 11 are synchronized in power. The system controls the flow of water inside the main curved coil 501 to achieve pressurization and pressure stabilization. At this point, the connection between the top sealing cover 1004 and the flange ring 1005 is opened, and the top sealing cover 1004 is pulled out, bringing out the guide arc 1003 and the hollow ring plate 1006 via the connecting rod 1002. The filter element assembly 15 is then removed. Under the action of the booster pump 4 and the pumping and pressure-reducing pump 11, the water pressure inside the main curved coil 501 remains unchanged. The filter element assembly 15 can then be hooked out, cleaned, and promptly reinserted. The connecting rod 1002, guide arc 1003, and top sealing cover 1004 are then returned to their original positions. Returning to its original position facilitates cleaning and maintenance during wastewater operation, increasing convenience without requiring shutdown. Furthermore, if blockage occurs, the vibration force, supported by the shock absorber 7 and support rod 6, causes the main curved coil 501 to vibrate and dislodge the blockage particles. These particles fall inside the ultrafiltration filter element 1502 and the sparse metal mesh cylinder 1506, through the folds and gaps of the ultrafiltration filter element 1502, and are guided back to the bottom of the bend in the main curved coil 501 via the guide groove 508 and guide hole 509. This, combined with the vibration effect, further enhances the cleaning effect.

[0040] In another implementation scheme, such as Figures 1-8As shown, the top of the corrugated pipe 402 is connected to a booster pump 4, the input end of the booster pump 4 is connected to a water inlet pipe 2, the other end of the water inlet pipe 2 is connected to a main threaded connector 201, the outer side of the booster pump 4 is fixedly sleeved with a support frame 401, the bottom of the support frame 401 is fixedly installed on the top of the base 1, the output end of the pump 11 is connected to a corrugated pipe 1102, the other end of the corrugated pipe 1102 is connected to a drain pipe 13, the outer side of the pump 11 is fixedly sleeved with a support frame 1101, the bottom end of the support frame 1101 is fixedly installed on the top of the base 1, both sides of the water inlet pipe 2 are connected to threaded connectors 3, both sides of the drain pipe 13 are connected to threaded connectors 14, and threaded connectors 9 are movably installed on the opposite sides of threaded connectors 3 and 14.

[0041] The booster pump 4 and the depressurization pump 11 are designed to internally pressurize and depressurize the two ends of the main curved coil 501, thereby balancing the pressure as needed and enabling filtration with the ultrafiltration filter element, which helps to increase the filtration effect. The function of the first bellows 402 and the second bellows 1102 is to dampen the vibration when the main curved coil 501 vibrates, so that the vibration force is not transmitted. The first threaded connector 3 and the second threaded connector 14 are used to connect multiple curved coil mechanisms 5 and the second processing mechanism 12 in series, which facilitates the expansion of the filtration effect, thereby increasing the filtration efficiency and reducing the cleaning and maintenance cycle, and making it convenient for multiple devices to be connected in series.

[0042] In another implementation scheme, such as Figures 1-8 As shown, the threaded connector 9 includes a reverse nut 901, several fastening bolts 903, and two flange rings 902. The two flange rings 902 are respectively fixedly sleeved on the outside of the threaded connector 3 and the threaded connector 14. The fastening bolts 903 are movably inserted into the inside of the flange rings 902. A sealing washer 904 is movably sleeved on the inside of the reverse nut 901. Symmetrical threads are opened inside both ends of the reverse nut 901. The inside of the reverse nut 901 is threadedly connected to the outside of the two threaded connectors 3 through the symmetrical threads.

[0043] When connecting, the flange plate of flange ring 902 is connected to the outside of threaded connector 3 and threaded connector 2 14, and is connected to threaded connector 3 and threaded connector 2 14 by reverse nut 901. Threaded connector 3 and threaded connector 2 14 are provided with threads on the outside that are compatible with reverse nut 901. Rotating reverse nut 901 causes threaded connector 3 and threaded connector 2 14 connected at both ends to be connected and match in the connection of opposing threads. The sealing gasket 904 is located at the connection position of threaded connector 3 or threaded connector 2 14. After rotational connection, the connection is fixed by inserting fastening bolt 903 into the flange, which facilitates fixed connection and facilitates connection between bending coil mechanism 5 and second processing mechanism 12 and bending coil mechanism 5, and facilitates tandem assembly.

[0044] In another implementation scheme, such as Figures 1-5 As shown, the slag discharge mechanism 8 includes a slag discharge pipe 801, which is L-shaped and its top end is connected to the inside of the main bending coil 501. A filter cylinder 804 is movably sleeved on the inner side of the far end of the slag discharge pipe 801. A rubber guide cone ring 805 is fixedly installed on one end of the filter cylinder 804 and is movably sleeved inside the slag discharge pipe 801. A threaded sealing cap 802 is fixedly installed on the other end of the filter cylinder 804. The inner side of the threaded sealing cap 802 is threadedly connected to the outer side of the slag discharge pipe 801. A switch valve 803 is movably installed inside the top end of the slag discharge pipe 801.

[0045] When it is necessary to clean the sediment, first open the switch valve 803. After opening the switch valve 803, the sediment will accumulate at the bottom of the bend of the main curved coil 501. The sediment will gradually accumulate inside the slag discharge pipe 801. With the sealing effect of the threaded sealing cap 802 on the slag discharge pipe 801, the sediment accumulates inside the slag discharge pipe 801 without leakage. It then enters the inner side of the filter cylinder 804 through the guide ring 805. When cleaning is required, close the switch valve 803 and rotate the threaded sealing cap 802 to release the blockage of the slag discharge pipe 801. At this time, the water flows out from the gap between the threaded sealing cap 802 and the slag discharge pipe 801, while the impurities are carried out under the filter screen of the filter cylinder 804. After cleaning, the filter cylinder is refilled, and the switch valve 803 is opened to continue the next cycle. This facilitates cleaning and maintenance, reduces the labor intensity of the operators, and increases the service effectiveness of the structure.

The sparse metal mesh cylinder 1506 and the ultrafiltration filter element 1502 are movably sleeved on the outer side of the hollow tube 502. The dimensions of the sealing ring 1505 are adapted to the dimensions of the sealing ring groove 505. The bottom of the bottom ring plate 1504 is in movable contact with the top of the support ring 504. The top of the top support plate 1501 is in movable contact with the bottom of the hollow ring plate 1006. The dimensions of the ultrafiltration filter element 1502 are adapted to the dimensions of the hollow tube 502.

[0047] The ultrafiltration filter element 1502 has a specially designed folded, corrugated shape for easy operation. The filter element assembly 15 is installed inside the main curved coil 501 and outside the hollow tube 502 for easy installation. The filter pores of the ultrafiltration filter element 1502 are available in various sizes, allowing for different settings from large pores to ultrafiltration effects to meet different needs. During the series assembly process, different sizes of filter element assemblies 15 can be installed inside the main curved coil 501 according to different needs, facilitating coordinated operation, easy disassembly, cleaning and maintenance, convenient filtration operation, and wastewater recycling.

[0048] In another implementation scheme, such as Figure 1 and Figure 2 As shown, the specifications and dimensions of the second processing mechanism 12 are consistent with those of the bending coil mechanism 5. The two ends of the second processing mechanism 12 are connected to the threaded connecting part 3 and the threaded connecting part 14 respectively through the threaded connecting parts 9.

[0049] The second processing mechanism 12 is connected to the bending coil mechanism 5 through a connector that adapts to the bend and threaded connector 3 and threaded connector 14. The second processing mechanism 12 is the edge connecting component of the bending coil mechanism 5 in the series state. After multiple bending coil mechanisms 5 are connected in series, they are distributed at the edge through the second processing mechanism 12, which increases the effect of multiple series groups and makes it easy to use.
