Description

Technical Field

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

[0002] Printing and dyeing, also known as dyeing and finishing, is a processing method in the textile process. It is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. The surface of rayon is colored by dyes to change the color of rayon, improve the color diversity during textile production, and enhance the textile effect. In the silk printing and dyeing process, printing and dyeing wastewater is generally recycled and treated through treatment equipment to reduce the pollution of wastewater to the environment. The treatment equipment includes a pre-treatment unit that uses a grid to preliminarily remove large particles, sediments and other impurities in the wastewater, a biological treatment unit that uses a biofilm method to convert organic matter in the wastewater into more stable inorganic matter, a deep treatment unit that further treats the wastewater through adsorption to remove difficult-to-degrade organic matter and color substances, and a post-treatment unit for the final adjustment and purification of the treated water quality to meet reuse or discharge standards. Then the treatment equipment mainly relies on a combination of physical, chemical and biological methods to remove pollutants in the wastewater or convert them into harmless substances.

[0003] In existing treatment equipment, the pretreatment unit uses a grid to preliminarily remove large particles, sediments and other impurities in the wastewater. Generally, the grid is used to salvage, separate and remove impurities in the wastewater. The grid blocks the generated fluff, especially the fluff. After the fluff is blocked by the grid, the filter holes of the grid will be blocked. Dense fluff will block the filter holes to a higher degree. Even if the wastewater is salvaged through the grid, the wastewater is not filtered effectively. During the filtration, the fluff is collected and returned to the wastewater through the filter holes. Therefore, when the fluff needs to be cleaned, it needs to be processed without wastewater. Waiting for the wastewater to be filtered before cleaning the fluff will result in poor filtration effect. Based on this, it is necessary to clean the fluff synchronously during the filtration of the wastewater and prevent the fluff from returning to the filtered wastewater. Summary of the Invention

DETAILED DESCRIPTION

[0032] 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 creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-10The present invention provides a technical solution. When cleaning the lint, it is necessary to process it without wastewater. Waiting for the wastewater to be filtered before cleaning the lint will make the filtering effect poor. It is necessary to clean the lint synchronously during the filtration of the wastewater, and prevent the lint from returning to the filtered wastewater. A textile printing and dyeing wastewater recycling and treatment device is proposed, including a frame 1, a support cylinder 2 and a rotating drum 3. The support cylinder 2 is rotatably installed in the frame 1, and the rotating drum 3 is supported on the support cylinder 2. The rotating drum 3 is rotatable. End covers 4 are fixed at both ends of the rotating drum 3. A gear end 5 is fixed outside the end cover 4. The axis of the gear end 5 A water diversion pipe 6 is inserted on the top, and the water diversion pipe 6 is used to transmit wastewater through the drum 3. An inner filter drum 9 and an inner support frame 10 are provided inside the drum 3. An inner mesh drum 11 is provided inside the inner filter drum 9. An inner cleaning part 12 is provided inside the inner mesh drum 11. The inner cleaning part 12 is used to clean the fluff on the inner wall of the inner mesh drum 11. The inner filter drum 9 is used to block the cleaned outer side of the inner mesh drum 11 to prevent the fluff from moving out with the wastewater. The wastewater enters from the water diversion pipe 6 at one end, moves out of the inner filter drum 9 through the inner mesh drum 11, and then passes through the inner support frame 10 and is discharged from the water diversion pipe 6 at the other end. The wastewater is filtered inside the inner mesh drum 11.

[0034] like Figure 1 As shown, a bracket 7 is fixed to the outside of the water pipe 6, and the bracket 7 is fixed on the frame 1. The bracket 7 is used to support the water pipe 6. A motor 8 is provided on the outside of the gear end 5 at one end. The motor 8 is installed on the frame 1 and is used to drive the gear end 5 to rotate. The water pipes 6 at both ends remain stationary, and the motor 8 drives the gear end 5 and the end cover 4 to rotate, and the rotating drum 3 rotates accordingly.

[0035] like Figure 5 As shown, the inner filter cartridge 9 and the inner support frame 10 are respectively fixed to the inner sides of the end covers 4 at both ends. The inner filter cartridge 9 rotates with the end cover 4, and the inner filter cartridge 9 is abutted against the inner support frame 10. The inner support frame 10 is hollowed out and is used to connect the rotating drum 3 with the water diversion pipe 6 at one end, and the water diversion pipe 6 at the other end is connected to the inside of the inner net cylinder 11, so that the wastewater moves from the inner net cylinder 11 to the outside of the inner filter cartridge 9, and then moves out from the water diversion pipe 6 at one end. It should be noted that the inner support frame 10 is used to support the inner filter cartridge 9, while also keeping the water diversion pipe 6 at one end connected to the inside of the rotating drum 3, and remains stable during the rotation of the rotating drum 3.

[0036] like Figure 5As shown, the outer wall of the inner filter cylinder 9 is provided with an array of water outlet grooves 91, and the water outlet grooves 91 are used for discharging waste water. An array of inner retaining rings 92 are fixed on the inner wall of the inner filter cylinder 9. The inner retaining rings 92 and the water outlet grooves 91 are arranged at intervals. The water outlet grooves 91 connect the inner net cylinder 11 with the inside of the rotating drum 3 and are used to discharge the waste water inside the inner net cylinder 11 to avoid blockage. The inner retaining ring 92 contacts the inner net cylinder 11, so that the position where the inner net cylinder 11 is contacted is prevented from moving outward. The inner net cylinder 11 at the position blocked by the inner retaining ring 92 can be cleaned by the inner cleaning part 12. During the cleaning process, it is easy for lint to move out of the inner net cylinder 11. After being blocked, outward water flow is avoided, and lint is prevented from moving outward during the cleaning process.

[0037] like Figure 5 As shown, there is a circle of filter screen on the outer wall of the inner net tube 11, so that the wastewater is filtered from the inside to the outside. The outer side of the inner net tube 11 is in contact with the inner retaining ring 92 of the array, and the inner cleaning part 12 is used to clean the inner net tube 11 that is blocked on the inner side of the inner retaining ring 92.

[0038] like Figure 6 As shown, one end of the inner net tube 11 is sleeved with the water diversion pipe 6, and a guide edge 113 is provided on the outer wall of the water diversion pipe 6. The end of the inner net tube 11 that cooperates with the guide edge 113 has a polygonal opening 111. The water diversion pipe 6 and the guide edge 113 are sleeved in the polygonal opening 111. When the water diversion pipe 6 remains stationary, the water diversion pipe 6 and the guide edge 113 cooperate with the polygonal opening 111, so that the position of the polygonal opening 111 is maintained to avoid rotation. When the inner net tube 11 performs telescopic movement, the polygonal opening 111 slides along the water diversion pipe 6 and the guide edge 113, so that the inner net tube 11 can perform telescopic reciprocating movement. In addition, under the support of the outer inner retaining ring 92, the inner net tube 11 can be prevented from being deformed.

[0039] like Figure 6 As shown, a circle of driving ring 112 is fixed to one end of the inner net cylinder 11. The outer side of the driving ring 112 is concave and convex, and its outer side surface is provided with a push rod 114. The push rod 114 is fixed to the end cover 4. When the push rod 114 rotates with the end cover 4, the push rod 114 moves along the end face of the driving ring 112. The end face of the driving ring 112 is concave and convex, so that the inner net cylinder 11 can move back and forth. When the push rod 114 rotates, it cooperates with the concave and convex surface of the outer side of the driving ring 112 to push the inner net cylinder 11 to move back and forth. The other end of the inner net cylinder 11 is fixed with a support spring 115 for supporting the inner net cylinder 11. The support spring 115 is supported in the inner filter cylinder 9. The support spring 115 is used to reset the inner net cylinder 11 after movement.

[0040] like Figure 8As shown, there is a cavity 121 between the ends of the inner filter cylinder 9 and the inner mesh cylinder 11. The support spring 115 is arranged inside the cavity 121, so that the inner mesh cylinder 11 can perform telescopic movement, and there is a certain space. At the same time, the support spring 115 also has installation space.

[0041] like Figure 8 As shown, the inner end face of the inner filter cylinder 9 is also fixed with an inner shaft 122 extending into the inner mesh cylinder 11, and the end face of the inner shaft 122 is provided with a polygonal hole 123. The inner cleaning part 12 includes a polygonal shaft 124 embedded in the polygonal hole 123, and a cleaning rod 125 is fixed to the outer end of the polygonal shaft 124. A plurality of cleaning sheets 13 are fixed to the outer side of the cleaning rod 125. The cleaning sheets 13 correspond to the inner retaining ring 92 one by one. When the inner mesh cylinder 11 moves in a telescopic manner, the inner filter cylinder 9 and the inner cleaning part 12 cooperate and can only rotate to clean the fluff on the inner wall of the inner mesh cylinder 11.

[0042] like Figure 9 As shown, the cleaning sheet 13 includes a ring body 131, and rigid fluff 132 is fixed to the outside of the ring body 131. The fluff 132 is used to clean the lint on the inner wall of the inner net cylinder 11. The fluff 132 is used to brush off the lint to prevent it from adhering to the inner wall of the inner net cylinder 11. At the same time, during the cleaning process, the inner net cylinder 11 reciprocates and is cleaned back and forth, ensuring that the position after cleaning can filter the wastewater, avoiding the increase of internal water pressure as much as possible, and avoiding squeezing out the lint;

[0043] like Figure 10 As shown, the interior of the ring body 131 has an integrally formed triangular piece 133 and a triangular opening 134. The triangular piece 133 has a filter hole. The triangular piece 133 is fixed to the cleaning rod 125. The triangular openings 134 of adjacent ring bodies 131 are staggered. The triangular piece 133 is used to block lint, but wastewater and lint can move inward from the triangular openings 134. The staggered triangular openings 134 of adjacent ring bodies 131 ensure the passage of wastewater and also block lint on the triangular piece 133 as much as possible, reducing the lint from adhering to the inner net cylinder 11. It can also prevent the water pressure in a local position inside the inner net cylinder 11 from increasing, causing the lint to be squeezed out of the inner net cylinder 11. It should be noted that one end of the drive ring 112 of the inner net cylinder 11 is detachable, so that the inner net cylinder 11 can be opened and the internal cleaning part 12 inserted therein can be removed for cleaning, thereby preventing excessive accumulation of lint and affecting the filtering effect.

[0044] The working principle of the present invention is as follows: the motor 8 drives the gear end 5 and the drum 3 to rotate, and the water pipes 6 at both ends are used to transmit wastewater, and the wastewater is processed through the drum 3, wherein the water pipes 6 at both ends remain fixed, and the inner filter drum 9 and the inner cleaning part 12 inside the drum 3 rotate with the drum 3, and the inner net drum 11 is limited by the water pipe 6 at one end and remains fixed. It rotates through the push rod 114, and the drive ring 112 remains stationary. The push rod 114 moves along the concave and convex surface of the drive ring 112, squeezing the drive ring 112, so that the drive ring 112 drives the inner net drum 11 to telescopically move along the inner filter drum 9, and the inner net drum 111 is supported by the support spring. The inner mesh tube 11 is reset under the action of the spring 115, so that the inner retaining ring 92 is covered at different positions of the inner mesh tube 11, so that the different positions of the inner mesh tube 11 cooperate with the water outlet trough 91, so that the water in the inner mesh tube 11 moves out from the water outlet trough 91 to complete the filtration. Since the cleaning piece 13 corresponds to the inner retaining ring 92, when the cleaning piece 13 cleans the fluff on the inside of the inner mesh tube 11, it ensures that the cleaning position will not have wastewater moving outward, and avoids the fluff being filtered out with the wastewater as much as possible. In addition, during the reciprocating motion of the inner mesh tube 11, different positions of the inner mesh tube 11 can be cleaned, which solves the problem of filtration and avoids the problem of blockage.

[0045] Secondly, by driving the motor 8, the inner net cylinder 11 can be cleaned during filtering without the need for additional driving action, thereby simplifying the structure and making it less prone to damage.

[0046] Adjacent ring bodies 131 have triangular pieces 133 arranged alternately, so that when wastewater enters the inner mesh tube 11, it can be preliminarily filtered by the triangular pieces 133, so that the wastewater can fill the inner mesh tube 11, avoiding excessive pressure in the local position of the inner mesh tube 11, which may cause the fluff to be squeezed out of the inner mesh tube 11.
