Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically referring to a wastewater treatment device for textiles. Background Technology

[0002] The textile industry is a vital pillar industry for people's livelihood in my country, but it is also a high-water-consuming and high-polluting industry. It is estimated that dyeing and printing enterprises consume 3 to 5 tons of water to process 100 meters of fabric. The resulting large amount of wastewater has a complex composition, containing various pollutants such as short fibers, dyes, sizing agents, and surfactants, making it extremely difficult to treat. In particular, the special solid-liquid mixing characteristics of textile wastewater, especially the coexistence of high concentrations of short fibers (cotton wadding, chemical fibers, etc.) and viscous flocculent matter, pose a severe challenge to traditional wastewater treatment equipment in the pretreatment stage.

[0003] Textile wastewater, after initial filtration, produces a large amount of fibrous flocculent precipitate. This precipitate has extremely poor fluidity at the bottom of the sedimentation tank, leading to poor sludge discharge. In severe cases, the sludge discharge pipe becomes completely blocked, requiring manual cleaning to restore its function. Long-term accumulation of precipitate also occupies the effective volume of the tank, shortening the hydraulic retention time of the wastewater and reducing the efficiency of subsequent biological or advanced treatment. Existing sludge discharge methods mostly rely on gravity flow, but gravity sludge discharge is insufficient for viscous precipitate. It can only clean some precipitate that still retains some fluidity and cannot completely remove precipitate attached to the bottom wall of the tank. Some mechanical sludge scraping devices, while cleaning precipitate, also stir up the already settled impurities, causing pollution. The only way to deal with this is by increasing the maintenance frequency and adding redundant equipment, rather than fundamentally solving the problem at the mechanical structure level. Therefore, there is an urgent need for a wastewater treatment device that fundamentally improves the mechanical structure to break through the existing technological bottlenecks. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a wastewater treatment device for textiles, which effectively solves the above problems.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides a wastewater treatment device for textiles, including a wastewater tank, a tilting bottom plate, a driving mechanism and a filter cake mechanism. The wastewater tank includes a water storage area and a filter cake area. The filter cake area is located at the bottom of the water storage area. The tilting bottom plate is rotatably located between the filter cake area and the water storage area. The tilting bottom plate is arranged in a linear array. The driving mechanism is symmetrically located on both sides of the wastewater tank. The filter cake mechanism is slidably located within the filter cake area.

[0006] Furthermore, the bottom wall of the sewage tank is provided with a sliding groove, and an electric screw is rotatably installed in the sliding groove. A reserved groove is provided at one end of the filter residue area, and an auxiliary groove is provided above the sliding groove. The width of the sliding groove is smaller than the width of the auxiliary groove. Reserved openings are provided at both ends of the auxiliary groove. The reserved openings penetrate the wall of the sewage tank. A storage roller is provided at the top of the reserved opening. The storage roller can be electrically controlled to rotate. Drive motors are symmetrically provided on the outer wall of the sewage tank. Rotating rods are symmetrically provided on both sides of the sewage tank. The output end of the drive motor is connected to the rotating rod. The rotating rod is provided with a threaded section. Through holes are linearly arrayed on the side wall of the sewage tank.

[0007] Furthermore, the flip-over base plate includes a partition and gears. The partition is rotatably positioned at the through hole, and the gears are symmetrically positioned at both ends of the partition. The gears pass through the through hole and are positioned outside the sewage tank. A sealing strip is provided along the outer edge of the partition.

[0008] When the flip-over base plate is in a horizontal state, the flip-over base plates are tightly attached to each other by sealing strips, separating the water storage area from the filter residue area.

[0009] Furthermore, the filter cake mechanism includes a slider and a filter plate. The slider is slidably disposed in the chute, and the filter plate is disposed on the top of the slider. The filter plate is L-shaped, and a vibration module is provided on the top of the filter plate. When the slider is located at one end of the chute close to the reserved groove, the filter plate is located in the reserved groove. Sealing strips are provided on both sides of the slider, and the sealing strips are disposed in the auxiliary groove. The two ends of the sealing strips pass through the reserved opening and are coiled on the storage roller. A second threaded hole is provided on the slider, and the second threaded hole engages with the threaded electric screw.

[0010] The sealing strip prevents sediment from entering the chute and adhering to the electric screw, thus affecting the operation of the thread structure.

[0011] The height of the filter plate can separate the filter cake zone. Through the cooperation of the electric screw and the threaded hole two, rotating the electric screw can make the filter cake mechanism slide along the slide groove, thereby controlling the filter plate to filter the sediment in the filter cake zone by physical extrusion. At the same time, the vibration module can clean the bottom of the flip-over base plate by vibration and remove the impurities attached to its surface.

[0012] Furthermore, the driving mechanism includes a rack that meshes with a gear. The rack is in close contact with the outer wall of the sewage tank, and a threaded hole is provided inside the rack, which meshes with a threaded section.

[0013] The drive motor controls the rotation of the rotating rod, and through the cooperation of the threaded section and the threaded hole, controls the movement of the rack, thereby controlling the flipping of the base plate through the gear.

[0014] The water storage area and the filter residue area have independent drainage outlets.

[0015] The wastewater tank has a cleaning port on the side wall of the filter cake area. The cleaning port is located on the side of the filter cake mechanism away from the reserved groove. The cleaning port is equipped with a cover plate, which can be opened by the staff to clean the impurities in the filter cake area and the filter plate.

[0016] The beneficial effects of the present invention using the above structure are as follows: The textile wastewater treatment device provided by this solution, under normal conditions, allows wastewater to be treated in a storage area. The rotating bottom plate is in a horizontal state, separating the storage area from the filter cake area. When it is necessary to clean the sediment, the rotating bottom plate is slightly opened. Under the influence of gravity and water pressure, the sediment with a certain degree of flowability at the bottom of the water quickly flows into the filter cake area through the gaps between the rotating bottom plates, preventing it from being stirred up and polluting the water during the cleaning process. After the filter cake area is filled with water, the rotating bottom plate is slowly rotated completely 180°, so that the surface that was originally the bottom wall of the storage area becomes the top wall of the filter cake area. Subsequently, the filter cake mechanism is controlled to slide along the chute, cleaning the filter cake area... Wastewater is physically intercepted and separated, trapping impurities on the side of the filter plate away from the pre-reserved groove. During the process, the vibration module also cleans the impurities attached to the flipping bottom plate, ensuring that the cleaned surface is clean when flipped back to the water storage area. The remaining wastewater in the water storage area and the filter residue area can enter the next step of wastewater treatment through the drain outlet. This method can effectively clean the water storage tank of textile wastewater rich in a large amount of sediment, keeping the tank unobstructed, preventing blockages and sediment accumulation that would occupy the effective volume of the tank, and improving wastewater treatment efficiency. At the same time, the direction of sediment is controlled during the cleaning process to prevent the sediment from being broken up and causing pollution again, greatly reducing the maintenance frequency and improving the efficiency of textile wastewater treatment.

[0022] like Figures 1-8 As shown, the present invention provides a wastewater treatment device for textiles, including a wastewater tank 1, a tilting bottom plate 2, a drive mechanism 3, and a filter cake mechanism 4. The wastewater tank 1 includes a water storage area 101 and a filter cake area 102. The filter cake area 102 is located at the bottom of the water storage area 101. The tilting bottom plate 2 is rotatably located between the filter cake area 102 and the water storage area 101. The tilting bottom plates 2 are arranged in a linear array. The drive mechanism 3 is symmetrically located on both sides of the wastewater tank 1. The filter cake mechanism 4 is slidably located within the filter cake area 102.

[0023] The bottom wall of the sewage tank 1 is provided with a chute 103, and an electric screw 104 is rotatably installed in the chute 103. A reserved groove 106 is provided at one end of the filter cake area 102. An auxiliary groove 105 is provided above the chute 103. The width of the chute 103 is smaller than the width of the auxiliary groove 105. Reserved openings 111 are provided at both ends of the auxiliary groove 105. The reserved openings 111 penetrate the tank wall of the sewage tank 1. A storage roller 112 is provided at the top of the reserved opening 111. The storage roller 112 can be electrically controlled to rotate. A drive motor 110 is symmetrically provided on the outer wall of the sewage tank 1. Rotating rods 108 are symmetrically provided on both sides of the sewage tank 1. The output end of the drive motor 110 is connected to the rotating rod 108. A threaded section 109 is provided on the rotating rod 108. Through holes 107 are linearly arrayed on the side wall of the sewage tank 1.

[0024] The flip-over base plate 2 includes a partition 201 and a gear 203. The partition 201 is rotatably positioned at the through hole 107. The gear 203 is symmetrically positioned at both ends of the partition 201. The gear 203 passes through the through hole 107 and is positioned on the outside of the sewage tank 1. A sealing strip 202 is provided on the outer edge of the partition 201.

[0025] When the flip-top plate 2 is in a horizontal state, the flip-top plate 2 is tightly attached to each other by the sealing strip 202, separating the water storage area 101 from the filter residue area 102.

[0026] The filter mechanism 4 includes a slider 401 and a filter plate 404. The slider 401 is slidably disposed in the chute 103, and the filter plate 404 is disposed on the top of the slider 401. The filter plate 404 is L-shaped, and a vibration module 405 is provided on the top of the filter plate 404. When the slider 401 is located at one end of the chute 103 near the reserved groove 106, the filter plate 404 is located in the reserved groove 106. Sealing strips 403 are provided on both sides of the slider 401. The sealing strips 403 are disposed in the auxiliary groove 105. The two ends of the sealing strips 403 pass through the reserved opening 111 and are coiled on the storage roller 112. A threaded hole 402 is provided on the slider 401, and the threaded hole 402 is threadedly engaged with the electric screw 104.

[0027] The height of the filter plate 404 can separate the filter cake zone 102. Through the cooperation of the electric screw 104 and the threaded hole 402, rotating the electric screw 104 can make the filter cake mechanism 4 slide along the slide groove 103, thereby controlling the filter plate 404 to filter the sediment in the filter cake zone 102 by physical extrusion. At the same time, the vibration module 405 can clean the bottom of the flipped bottom plate 2 and remove the sediment attached to its surface.

[0028] The drive mechanism 3 includes a rack 301, which meshes with a gear 203. The rack 301 is in close contact with the outer wall of the sewage tank 1. A threaded hole 302 is provided in the rack 301, which meshes with the threaded section 109.

[0029] The drive motor 110 controls the rotating rod 108 to rotate, and through the engagement of the threaded section 109 and the threaded hole 302, controls the rack 301 to move, thereby controlling the flipping of the flipping base plate 2 through the gear 203.

[0030] The water storage area 101 and the filter residue area 102 have independent drainage outlets.

[0031] The wastewater tank 1 has a cleaning port 113 on the side wall of the filter cake area 102. The cleaning port 113 is located on the side of the filter cake mechanism 4 away from the reserved groove 106. The cleaning port 113 is equipped with a cover plate 114. The staff can open the cover plate 114 to clean the impurities on the filter cake area 102 and the filter plate 404.

[0032] In practical use, under normal conditions, the wastewater is in the water storage area 101, and the wastewater tank 1 only serves as a container, which can be used for different scenarios as needed. The flip-top plate 2 is in a horizontal state, separating the water storage area 101 from the filter cake area 102. When it is necessary to clean the sediment, the drive motor 110 is started. The drive motor 110 controls the movement of the rack 301 by rotating the rotating rod 108. The rack 301 controls the flip-top plate 2 to tilt and open slightly through the gear 203. At this time, under the influence of gravity and water pressure, the sediment with a certain degree of flowability at the bottom of the water quickly flows into the filter cake area 102 through the gap between the flip-top plates 2 for partitioned storage, preventing it from being stirred up during the cleaning process and polluting the water quality. After the filter cake area 102 is filled with water, the flip-top plate 2 is controlled to rotate completely 180°. The flip-top plate 2 rotates slowly to prevent stirring up impurities. The flip-top plate 2 is originally the water storage area 102. The bottom wall of 01 flips over to become the top wall of the filter cake area 102, and at the same time, it separates the water storage area 101 from the filter cake area 102 again. Then, the electric screw 104 is controlled to rotate. The electric screw 104 controls the filter cake mechanism 4 to slide along the slide groove 103 through the threaded hole 402 on the slider 401. The filter plate 404 intercepts the sewage in the filter cake area 102 by physical interception and precipitation, and the impurities are intercepted on the side of the filter plate 404 away from the reserved groove 106. During the process, the vibration module 405 will also clean the impurities attached to the flipped bottom plate 2 by vibration, ensuring that the cleaned surface is clean after flipping back to the water storage area 101. After cleaning, the remaining wastewater in the water storage area 101 and the filter cake area 102 can enter the next step of wastewater treatment through the drain outlet. When the water in the filter cake area 102 is drained, the cover plate 114 can be opened and the impurities can be cleaned through the cleaning port 113.
