Description

Technical Field

[0001] This utility model relates to the field of cleaning tanks, specifically a sheet immersion cleaning tank and tank system. Background Technology

[0002] When producing sheet materials, such as filter membranes and coated membranes, multiple cleaning processes based on immersion are required. These processes may include washing, reaction, and cooling. The carrier for these reactions is a cleaning tank, which is filled with water, and the sheet material is then immersed in the cleaning tank to complete the process.

[0003] Existing cleaning tanks are mostly square tanks made of stainless steel or blocks. While these tanks are large, their processing efficiency is poor. Sheets cannot be fully cleaned or reacted during the process of entering and exiting the tank, resulting in large tank volumes, large floor space requirements, and low efficiency. Furthermore, each time new sheets are initially passed through the tank, manual intervention is required when problems such as shifting or wrinkling occur during the reaction, or when the reaction needs to be interrupted for other auxiliary processing. This is difficult and poses safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a sheet immersion cleaning tank and tank system that allows the sheet to repeatedly move in a serpentine pattern while being immersed, making full use of the space inside the tank and improving processing efficiency.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A sheet immersion cleaning tank includes a tank body with a groove at the top. A mounting frame is provided inside the tank body. The mounting frame includes a side frame and a base frame. The two sides of the base frame are fixedly connected to the bottom of the side frame to form a U-shaped structure. Upper rollers are equidistantly mounted on the top side of the side frame, and lower rollers are equidistantly mounted on the bottom side of the side frame. The number of lower rollers is one more than the number of upper rollers. The upper and lower rollers are staggered and of equal diameter. A horizontal shaft parallel to the upper rollers is symmetrically provided above the mounting frame. Both ends of the horizontal shaft are rotatably mounted to the side frame on the same side. Guide sprockets are provided at both ends of the horizontal shaft. Lower sprockets are provided at both ends of the lower rollers, and upper sprockets are provided at both ends of the upper rollers. Chains are provided on both sides of the mounting frame. The chains pass over two guide sprockets and then sequentially pass over adjacent upper and lower sprockets.

[0007] One of the horizontal shafts has a handwheel at one end.

[0008] The two ends of the top side of the side frame are respectively provided with rollers. The rollers are parallel to the upper rollers and at the same height, and the two rollers are symmetrically arranged relative to the outer side of all the upper rollers.

[0009] The side frame is equipped with multiple light rods, and a sliding sleeve is fixed on the side wall of the trough. The sliding sleeve is fixed to the upper part of the trough, and the light rod passes through the sliding sleeve and slides with the sliding sleeve.

[0010] The trough has an overflow weir on the top of one side wall parallel to the upper roller. The overflow weir includes a weir plate lower than the trough opening. The weir plate is arranged in parallel with the adjacent trough wall. The weir plate has triangular toothed grooves. The side wall of the trough has an overflow port that communicates with the bottom of the overflow weir.

[0011] The side wall of the tank is provided with an inlet and an outlet. The outlet is located at the bottom of the tank, and the inlet is located away from the overflow weir.

[0012] The water inlet is connected to the overflow outlet of the adjacent downstream tank via a pipeline.

[0013] A horizontal tube is provided above the groove, and the horizontal tube is arranged parallel to the upper roller. Liquid outlet pipes are provided at equal intervals below the horizontal tube.

[0014] The horizontal tube has fixing components at both ends. The fixing components include a lower mounting plate, an upper mounting plate, and a hoop plate. The lower mounting plate is welded and fixed to the groove. The upper mounting plates are arranged horizontally above the lower mounting plate. The middle part of the hoop plate is an upward-arched arc structure. The two ends of the horizontal tube are inserted into the arc structure. The two sides of the hoop plate are horizontal ear plates. The ear plates, the upper mounting plate, and the lower mounting plate are respectively provided with mounting holes on both sides. The mounting holes on each side pass through the mounting screws, and multiple large nuts are fitted on the mounting screws.

[0015] A sheet immersion tank system includes multiple sheet immersion cleaning tanks. The overflow port of one cleaning tank is connected to the inlet of an adjacent cleaning tank located upstream of it via a pipeline. The inlet of the cleaning tank located downstream is supplied with clean water.

[0024] The present invention will be further illustrated below with reference to specific embodiments.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0025] Example 1: A sheet immersion cleaning tank

[0026] This cleaning tank features an improved sheet material guiding structure, detailed below:

[0027] The cleaning tank includes a tank body 1 as a reaction vessel. The tank body 1 is a stainless steel settling tank structure with a rectangular cross-section, and the top of the tank body 1 is provided with a slot.

[0028] The side wall of the tank 1 is provided with an overflow weir 2, an inlet 5, an overflow outlet 3, and an outlet.

[0029] The water outlet is located at the bottom, and there are two water outlets located at the two sides of the side wall of the tank body 1. Each water outlet is equipped with an independently controlled electric valve. By starting and closing the water outlet valve, one side can be emptied or both outlets can be emptied.

[0030] The tank body 1 has an overflow weir 2 on one side wall adjacent to the outlet. The overflow weir 2 is located at the upper part of the tank body 1. The overflow weir 2 includes a weir plate 4 lower than the tank opening. The weir plate 4 is arranged side by side with the adjacent tank wall, and triangular grooves are distributed on the weir plate 4. An overflow port 3 is connected through the side wall of the tank body 1 and communicates with the overflow weir 2.

[0031] The inlet 5 is located at the upper part of the tank body 1, and is positioned away from the edge of the tank wall away from the overflow weir 2. It is used to connect and replenish the liquid, or to connect with the overflow port 3 of the downstream cleaning tank via a pipeline, introducing water from the downstream cleaning tank into this cleaning tank to replenish it with cleaner water.

[0032] A horizontal pipe 6 is provided above the groove opening. The horizontal pipe 6 is set perpendicular to the material conveying direction of the sheet. The horizontal pipe 6 is fixed horizontally above the groove opening. Liquid outlet pipes 7 are provided at equal intervals below the horizontal pipe 6. The liquid outlet pipes 7 are used to discharge water downwards to beat the liquid in the tank 1, improve the mixing and disturbance effect, promote full contact between the clean water and the sheet, and improve the rinsing effect.

[0033] The horizontal pipe 6 has fixing components at both ends, including a lower mounting plate 8, an upper mounting plate 9, and a clamping plate 10. The lower mounting plate 8 is welded and fixed to the groove. The upper mounting plates 9 are arranged horizontally above the lower mounting plate 8. The middle part of the clamping plate 10 is an upward-arched arc structure, and the two ends of the horizontal pipe 6 are inserted into the arc structure. The two sides of the clamping plate 10 are horizontal ear plates 11. The ear plates 11, the upper mounting plate 9, and the lower mounting plate 8 are respectively provided with mounting holes. The mounting holes on each side pass through the mounting screws 12. The mounting screws 12 are fitted with multiple large nuts. The clamping of the clamping plate 10 and the upper mounting plate 9 by the large nuts achieves the clamping and fixing of the two ends of the horizontal pipe 6. The large nuts also fix the lower mounting plate 8 and the upper mounting plate 9, and make the fixing height of the upper mounting plate 9 relative to the lower mounting plate 8 adjustable. This makes the height of the horizontal pipe 6 relative to the groove adjustable, thereby changing the effect of water flow and improving the adjustment of turbulence.

[0034] The tank 1 is provided with a U-shaped mounting frame, which includes a side frame 13 and a base frame 14. The two sides of the base frame 14 are fixedly connected to the bottom side of the side frame 13 to form a U-shaped structure. The base frame 14 is adapted to the bottom surface of the tank 1. One side of the side frame 13 is located near the water outlet and water inlet 5.

[0035] Upper rollers 15 are equidistantly mounted on the top side of the side frame 13, and lower rollers 16 are equidistantly mounted on the bottom side of the side frame 13. The upper rollers 15 and lower rollers 16 have the same diameter. The lower rollers 16 are arranged between adjacent upper rollers 15, so that the upper rollers 15 and lower rollers 16 are staggered. The spacing between the upper rollers 15 and the spacing between the lower rollers 16 are equal and are both equal to the diameter of the upper rollers 15 and lower rollers 16. When the sheet alternately passes around the upper rollers 15 and lower rollers 16, it can achieve serpentine conveying, maximize the use of the space in the groove, and allow the sheet to be retained in the groove for a longer time.

[0036] In this example, there are 155 upper rollers and 166 lower rollers. Therefore, the lower rollers 16 are wider than the upper rollers 15. After the sheet enters, it first passes around the lower rollers 16, then repeatedly passes around the upper rollers 15 and the lower rollers 16, and finally passes around the lower rollers 16 again before leaving the tank 1. This more effectively pulls the sheet into the immersion tank.

[0037] The two ends of the top side of the side frame 13 are respectively provided with rollers 17. The rollers 17 are used to constrain the sheet and prevent the sheet from touching the tank wall when entering and leaving the tank body 1. The rollers 17 are set at the same height as the upper roller 15.

[0038] A horizontal shaft 18 is symmetrically arranged above the mounting frame. The horizontal shaft 18 is parallel to the upper rollers 15 and is symmetrically arranged on both sides of all the upper rollers 15. Specifically, bearing seats are symmetrically arranged above the side frame 13, and both ends of the horizontal shaft 18 are respectively installed with the bearing seats on the same side, allowing the horizontal shaft 18 to be rotatably installed relative to the mounting frame. One end of one of the horizontal shafts 18 is equipped with a handwheel 19, which allows for convenient manual control of the rotation of this horizontal shaft 18.

[0039] The horizontal shaft 18 has guide sprockets 20 at both ends, the lower roller 16 has lower sprockets 21 at both ends, and the upper roller 15 has upper sprockets 22 at both ends. Chains 23, which are loop-shaped roller chains, are provided on both sides of the mounting frame. These chains pass over two guide sprockets 20 and then sequentially pass over adjacent upper and lower sprockets 22 and 21, ensuring that all upper rollers 15 and lower rollers 16 rotate synchronously and in the same direction. Rotation can be manually controlled during machine stop, sheet loading / unloading, or adjustments, facilitating sheet handling. Not limited to this example, additional power can be added to drive the rotation of the upper rollers 15 and lower rollers 16.

[0040] Two optical rods 24 are symmetrically arranged on the side frame 13. The optical rods 24 are circular optical axes. A sliding sleeve 25 is fixed on the side wall of the groove 1. The sliding sleeve 25 is fixed to the upper part of the groove 1. The optical rods 24 pass through the sliding sleeve 25 and slide with the sliding sleeve 25 to realize the lifting and guiding of the entire mounting frame relative to the groove 1.

[0041] After the horizontal tube 6 is disassembled, the entire mounting frame can be lifted manually or using tools and equipment (such as lifting equipment). Workers can then complete the lifting and adjustment of the sheet material on the workbench on one side of the tank 1. Alternatively, a power structure can be added between the side frame 13 and the tank 1, such as installing a hydraulic cylinder on the tank 1. The end of the cylinder rod is fixed to the side frame 13, and the mounting frame is lifted by the hydraulic cylinder, which facilitates the lifting and operation of the entire mounting frame.

[0042] Therefore, the improved cleaning tank allows workers to easily handle sheet loading, unloading, sheet forming, and speed adjustment, greatly simplifying operations, reducing labor costs, and improving safety. Simultaneously, the alternating upper roller 15 and lower roller 16 guide the sheet, allowing it to repeatedly move in a serpentine pattern while immersed, fully utilizing the tank space and improving processing efficiency.

[0043] Example 2: A sheet immersion tank system

[0044] The system includes three sets of cleaning tanks as described in Example 1. During installation, the tanks are designated as tank 1, tank 2, and tank 3 according to the conveying direction of the sheet material. The overflow port 3 of tank 3 is connected to the inlet 5 of tank 2 via a pipeline. The overflow port 3 of tank 2 is connected to the inlet 5 of tank 1 via a pipeline. The outlet of tank 1 is kept draining water, which is collected for water treatment. The inlet 5 of tank 1 is connected to purified water to supplement the cleaning water for the entire system.

[0045] The water supply in the horizontal pipe 6 is drawn from the cleaning tank by a water pump, achieving self-circulation and self-disturbance to improve the cleaning effect.

[0046] After the water channels are connected as described above, the water in each cleaning tank is cleaner as it is soaked in the tanks. The last cleaning tank is for the final washing of the sheet, so it is necessary to continuously replenish clean water to keep it clean. By replenishing water in a sequential manner from back to front, water resources can be used efficiently and saved, which can both clean the sheet thoroughly and save water.
