Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, specifically to a cleaning tank for a chemically formed foil production line. Background Technology

[0002] With the development of electrolytic foil technology, product quality requirements are becoming increasingly stringent. The industry has placed higher demands on the electrolytic foil industry, requiring comprehensive control over the appearance of electrolytic foil and full inspection of the foil surface. Since the equipment was put into use, dirt has accounted for a large proportion of the defects that have caused the most trouble for the production line. Currently, the cleaning tanks of electrolytic foil production lines contain chemical raw materials (organic matter), and the temperature inside the tanks is maintained at 30-40 degrees Celsius year-round. The temperature of the cleaning water in the tanks is suitable for bacterial growth, and a group of bacteria that easily form flocculent matter will be adsorbed onto the foil surface. If it cannot be rinsed off, it will form dirt.

[0003] Existing cleaning tanks for electrolytic foil production lines reduce bacterial growth and accumulation by lowering the water level and controlling the water temperature. However, while lowering the water level can reduce water consumption in the short term, long-term water consumption due to repeated water changes is still a problem. Therefore, this method does not meet the current requirements. To address this, we propose a new cleaning tank for electrolytic foil production lines. Summary of the Invention

[0004] The purpose of this utility model is to provide a cleaning tank for a chemical foil production line, in order to solve the problem mentioned in the background art that the existing cleaning tanks for chemical foil production lines reduce the growth and accumulation of bacteria by lowering the water level in the washing tank and controlling the water temperature. However, although lowering the water level in the washing tank can reduce water consumption in the short term, long-term accumulation and water replacement will still cause water consumption problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleaning tank for a chemical foil production line, comprising a cleaning tank and a filtering tank, wherein the filtering tank is fixedly disposed on one side of the cleaning tank, a guide roller is provided inside the cleaning tank, an overflow hole is provided on one side above the guide roller and on the side wall of the cleaning tank, and a through hole is provided on one side of the filtering tank that communicates with the overflow hole, a fixing plate is fixedly disposed on both sides below the through hole and inside the filtering tank, a rectangular frame is placed between the upper parts of the two fixing plates, a filter screen is fixedly disposed inside the rectangular frame and near the through hole, and an activated carbon filter layer is fixedly disposed below the filter screen and inside the rectangular frame.

[0006] Preferably, a water pump is connected to one side of the filter tank via a connecting pipe, and a T-pipe is connected to the upper end of the water pump. Spray pipes are provided on both sides of the upper end of the cleaning tank. One end of each of the two spray pipes is connected to the T-pipe via a water pipe. Several downward-sloping nozzles are provided on the side of each of the two spray pipes that are close to each other.

[0007] Preferably, movable cavities are provided on both sides of the front end of the filter tank and above the fixed plate. Limiting blocks are slidably provided inside the movable cavities on both sides, and the ends of the two limiting blocks near the inside of the filter tank move through the movable cavities and extend into the inside of the filter tank.

[0008] Preferably, the upper end of the limiting block is provided with a driving groove with a right-angled trapezoidal structure, and the ends of the two limiting blocks away from the inside of the filter tank are fixedly connected to the inner wall of the movable cavity with springs, and the ends of the limiting blocks away from the springs in the natural state extend through the inside of the filter tank.

[0009] Preferably, the rectangular frame has limiting grooves corresponding to the limiting blocks at both ends on the side away from the through hole, and the end of the limiting block that extends through into the filter tank is inserted into the corresponding limiting groove.

[0010] Preferably, a threaded groove is vertically opened through one side of the upper end of the movable cavity, and a threaded rod is provided at the top of the filter groove and extends into the movable cavity. The bottom end of the threaded rod is in sliding contact with the inside of the drive groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, when the water level inside the cleaning tank exceeds the height of the overflow hole, the water enters the filter tank through the overflow hole and the through hole. The water entering the filter tank first passes through the filter screen to filter out flocculent matter, and then passes through the activated carbon filter layer to adsorb some organic matter in the water, thereby purifying the water entering the filter tank. Then, the water pump is started to transport the purified water through the three-way pipe to the water pipes on both sides. Through the connection with the spray pipe, the purified water is sprayed onto the foil surface through the nozzles in a cross-shear manner. This cycle is repeated so that the cleaning water can be purified and reused, which greatly reduces the consumption of fresh water and the amount of wastewater discharged. It can also remove stubborn pollutants from the foil surface and avoid uneven cleaning. 2. This utility model rotates the threaded rods on both sides of the upper end of the filter tank, so that both threaded rods are threaded through the threaded groove and move towards the inside of the movable cavity. The bottom end of the threaded rod is slidably connected to the inside of the drive groove, and along the inclined surface of the drive groove, pushes the limiting block to compress the spring, so that the limiting block is disengaged from the limiting groove and moves into the inside of the movable cavity, thereby releasing the limitation on the rectangular frame. Subsequently, the rectangular frame with filter screen and activated carbon filter layer can be disassembled from the inside of the filter tank for replacement or cleaning, thereby avoiding filter screen clogging or activated carbon filter layer adsorption saturation, which would affect the filtration of cleaning water.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figures 1 to 4 The present invention provides an embodiment of a cleaning tank for a chemical foil production line, comprising a cleaning tank 1 and a filter tank 3.

A through hole 301 is provided on one side of the filter tank 3 and is connected to the overflow hole 101. A fixing plate 9 is fixedly disposed on both sides below the through hole 301 and inside the filter tank 3. A rectangular frame 10 is placed between the upper parts of the two fixing plates 9. A filter screen 11 is fixedly disposed inside the rectangular frame 10 and on the side near the through hole 301. An activated carbon filter layer 12 is fixedly disposed below the filter screen 11 and inside the rectangular frame 10.

[0016] A water pump 4 is connected to one side of the filter tank 3 through a connecting pipe. A three-way pipe 5 is connected to the upper end of the water pump 4. Spray pipes 7 are provided on both sides of the upper end of the cleaning tank 1. One end of each spray pipe 7 is connected to the three-way pipe 5 through a water pipe 6. Several downward-sloping nozzles 8 are provided on the side of each spray pipe 7 that is close to each other.

[0017] The water entering the filter tank 3 first passes through the filter screen 11 to filter out flocculent matter, and then passes through the activated carbon filter layer 12 to adsorb some organic matter in the water, thereby purifying the water entering the filter tank 3. Then, the water pump 4 is started to transport the purified water through the three-way pipe 5 to the water pipes 6 on both sides. Then, through the connection with the spray pipe 7, the purified water is sprayed onto the foil surface through the nozzles 8 in a cross-cutting manner. This cycle is repeated so that the cleaning water can be purified and reused, which greatly reduces the consumption of new water and the amount of wastewater discharged. It can also remove stubborn pollutants from the foil surface and avoid uneven cleaning.

[0018] Movable cavities 303 are provided on both sides of the front end of the filter tank 3, above the fixed plate 9. Limiting blocks 13 are slidably installed inside each of the two movable cavities 303. The ends of the two limiting blocks 13 closest to the inside of the filter tank 3 penetrate the movable cavity 303 and extend into the interior of the filter tank 3. A drive groove 1301 with a right-angled trapezoidal structure is provided at the upper end of each limiting block 13. A spring 14 is fixedly connected between the ends of the two limiting blocks 13 furthest from the inside of the filter tank 3 and the inner wall of the movable cavity 303. In the natural state, the limiting blocks 13... The end of the filter 3 away from the spring 14 extends through into the interior of the filter 3. Both ends of the rectangular frame 10 away from the through hole 301 are provided with limiting grooves 1001 corresponding to the limiting block 13. The end of the limiting block 13 extending through into the interior of the filter 3 is inserted into the corresponding limiting groove 1001. A threaded groove 302 is vertically opened through one side of the upper end of the movable cavity 303. The top of the filter 3 is provided with a threaded rod 15 that extends through the threaded groove 302 and into the interior of the movable cavity 303. The bottom end of the threaded rod 15 slides in contact with the interior of the drive groove 1301.

[0019] By rotating the threaded rod 15, the threaded rod 15 is threaded through the threaded groove 302 and moves towards the interior of the movable cavity 303. The bottom end of the threaded rod 15 is slidably connected to the interior of the drive groove 1301, and along the inclined surface of the drive groove 1301, it pushes the limiting block 13 to compress the spring 14, causing the limiting block 13 to disengage from the limiting groove 1001 and move into the interior of the movable cavity 303, thereby releasing the restriction on the rectangular frame 10. Subsequently, the rectangular frame 10 equipped with the filter screen 11 and the activated carbon filter layer 12 can be disassembled from the interior of the filter tank 3 for replacement or cleaning.

[0020] When the cleaning tank of the electrolytic foil production line is in use, the electrolytic foil is guided into the cleaning tank 1 by the guide roller 2 for cleaning. When the water in the cleaning tank 1 exceeds the height of the overflow hole 101, the water enters the filter tank 3 through the overflow hole 101 and the through hole 301. The water entering the filter tank 3 first passes through the filter screen 11 to filter flocculent matter, and then passes through the activated carbon filter layer 12 to adsorb some organic matter in the water, thereby purifying the water entering the filter tank 3. Then, the water pump 4 is started to transport the purified water through the three-way pipe 5 to the water pipes 6 on both sides. Then, through the connection with the spray pipe 7, the purified water is sprayed onto the foil surface through the nozzles 8 in a cross-shear manner. This cycle is repeated so that the cleaning water can be purified and reused, which greatly reduces the consumption of new water and the amount of wastewater discharged. It can also remove stubborn contaminants from the foil surface and avoid uneven cleaning. After the cleaning tank of the electrolytic foil production line is used, the threaded rods 15 on both sides of the upper end of the filter tank 3 are rotated so that both threaded rods 15 are threaded through the threaded groove 302 and move into the interior of the movable cavity 303. The bottom end of the threaded rod 15 is slidably connected to the interior of the drive groove 1301, and along the inclined surface of the drive groove 1301, the limiting block 13 is pushed to compress the spring 14, so that the limiting block 13 is disengaged from the limiting groove 1001 and moved into the interior of the movable cavity 303, thereby releasing the limitation on the rectangular frame 10. Then the rectangular frame 10 with the filter screen 11 and activated carbon filter layer 12 can be disassembled from the interior of the filter tank 3 for replacement or cleaning, thereby avoiding the clogging of the filter screen 11 or the saturation of the activated carbon filter layer 12, which would affect the filtration of the cleaning water.
