Description

Technical Field

[0001] This utility model relates to the field of high-pressure aluminum foil production technology, and in particular to a chemical cleaning component for the production of medium and high-pressure anode foil. Background Technology

[0002] Anode foil is a key material in aluminum electrolytic capacitors, playing a decisive role in the capacitor's capacitance. With the rapid development of the information industry and the integration and miniaturization of electrical products, there is a growing demand for small-volume, high-capacity aluminum electrolytic capacitors, thus necessitating an improvement in the capacitance of the anode foil.

[0003] Traditional chemical cleaning equipment consists of a cleaning tank, fixed conveyor rollers, spray pipes, and waste liquid collection tanks. The working principle is that the anode foil is fed into the cleaning tank through the conveyor rollers, the spray pipes spray out cleaning liquid to rinse the surface of the foil, and the waste liquid after rinsing is directly discharged into the collection tank, and then discharged or discarded after simple filtration.

[0004] Traditional cleaning methods often involve a single spray followed by direct discharge. Even with simple filtration systems, these methods can only remove large particles and cannot effectively adsorb organic matter or adjust concentration. This results in high consumption and frequent replacement of the cleaning solution, increasing production costs and creating environmental pressure due to wastewater containing chemicals. Furthermore, the anode foil is conveyed via fixed rollers, lacking dynamic tension adjustment mechanisms at the feeding and discharging stages. Because the foil varies in thickness and is thin, sudden tension changes during start-up, acceleration, or deceleration can easily cause wrinkles or even tears. Especially under the impact of the cleaning solution spray, the foil is prone to lateral shift, leading to scratches from friction between the edges and the equipment, severely impacting the yield of the finished product.

[0005] Therefore, a chemical cleaning assembly for the production of medium and high voltage anode foil is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a chemical cleaning component for the production of medium and high pressure anode foil, which aims to improve the problems of high consumption of cleaning fluid, pollution emissions, and low yield of foil due to unstable tension in traditional equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a chemical cleaning assembly for the production of medium and high pressure anode foil, comprising a cleaning tank, a feed roller and a discharge roller fixedly installed on the upper side of the cleaning tank, a guide roller rotatably connected inside the cleaning tank, a storage tank installed on the cleaning tank, a water pump fixedly installed on the upper side of the storage tank, a water spray frame fixedly installed on the upper side of the storage tank, a nozzle fixedly installed on the lower side of the water spray frame, the output end of the water pump communicating with the water spray frame, a filter box fixedly installed on the right side of the cleaning tank, a filter screen and an activated carbon adsorption layer disposed inside the filter box, a replenishment tank fixedly installed on the right side of the storage tank, a circulation pump fixedly connected to the right side of the replenishment tank, a concentration sensor fixedly installed on the inner wall of the replenishment tank, and an adjustment assembly disposed between the feed roller and the discharge roller.

[0008] Furthermore, the adjustment assembly includes a sliding seat disposed between the feed roller and the discharge roller. A tension roller is rotatably connected to the inner side of the sliding seat, and a slider is fixedly connected to the outer side of the sliding seat. A vertical plate is fixedly connected to the washing tank, and a spring is fixedly connected to the lower side of the sliding seat. The side of the spring away from the sliding seat is fixedly connected to the washing tank.

[0009] Furthermore, a limiting groove is formed inside the vertical plate, and the slider is slidably connected inside the limiting groove.

[0010] Furthermore, the filter screen is positioned directly below the activated carbon adsorption layer.

[0011] Furthermore, the feed roller is located directly to the left of the discharge roller, and the guide roller is located below the feed roller and the discharge roller.

[0012] Furthermore, the circulating pump is connected to the upper side of the filter box, and the front side of the filter box is connected to the cleaning tank.

[0013] Furthermore, the tensioning roller is slidably connected to the upper side of the cleaning tank.

[0014] Furthermore, a controller is fixedly installed on the outer wall of the cleaning tank, and the controller is electrically connected to the circulation pump, water pump, circulation pump and concentration sensor.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, through multi-stage treatment of filtration, adsorption, and concentration adjustment, the cleaning solution is regenerated and circulated in a closed loop. The filter screen and activated carbon adsorption layer remove impurities, and the concentration sensor and replenishment mechanism maintain the cleaning solution's efficiency. While ensuring the cleaning effect, the consumption of new solution and wastewater discharge are reduced, thereby lowering the material costs and environmental pressure of production.

[0017] 2. In this utility model, the sliding structure of tension roller, spring and slider can be used to buffer and adjust the foil tension in real time according to the changes in foil tension, so as to avoid wrinkles, tears and other problems caused by sudden tension changes, and ensure the physical integrity of the anode foil during the cleaning process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3This utility model provides an embodiment of a chemical cleaning assembly for the production of medium and high voltage anode foil, comprising a cleaning tank 1, a feed roller 2 and a discharge roller 3 fixedly mounted on the upper side of the cleaning tank 1, a guide roller 4 rotatably connected inside the cleaning tank 1, the feed roller 2 being positioned directly to the left of the discharge roller 3, and the guide roller 4 being positioned below the feed roller 2 and the discharge roller 3, a storage tank 5 mounted on the cleaning tank 1, a water pump 6 fixedly mounted on the upper side of the storage tank 5, a spray frame 13 fixedly mounted on the upper side of the storage tank 5, and a spray nozzle 14 fixedly mounted on the lower side of the spray frame 13, the output end of the water pump 6 being connected to the spray frame 13. A filter box 7 is fixedly installed on the right side of the storage tank 5. The filter box 7 is equipped with a filter screen 8 and an activated carbon adsorption layer 9. The filter screen 8 is located directly below the activated carbon adsorption layer 9. A replenishment tank 11 is fixedly installed on the right side of the storage tank 5. A circulation pump 10 is fixedly connected to the right side of the replenishment tank 11. The circulation pump 10 is connected to the upper side of the filter box 7. The front side of the filter box 7 is connected to the cleaning tank 1. A concentration sensor 12 is fixedly installed on the inner wall of the replenishment tank 11. A controller 16 is fixedly installed on the outer wall of the cleaning tank 1. The controller 16 is electrically connected to the circulation pump 10, the water pump 6, the circulation pump 10, and the concentration sensor 12.

[0027] Specifically, the anode foil is smoothly introduced into the cleaning tank 1 via the feed roller 2, forming a continuous S-shaped path under the precise guidance of the guide roller 4. The discharge roller 3 is arranged horizontally and in a straight line with the feed roller 2 to ensure stable output of the anode foil. The water pump 6 delivers the cleaning solution in the storage tank 5 to the spray frame 13 at a constant pressure. The upper and lower surfaces of the anode foil are sprayed and cleaned by high-pressure spraying through the high-density arrangement of the nozzles 14. The used cleaning solution flows into the filter box 7 through the guide channel. First, it passes through the lower stainless steel filter screen 8 to intercept particulate impurities with a diameter greater than 5 micrometers. Then, it passes through the upper activated carbon adsorption layer 9 to remove organic matter and heavy metal ions from the cleaning solution. The circulation pump 10 delivers the two-stage purified cleaning solution to the replenishment tank 11. The concentration sensor 12 in the tank monitors the ion concentration of the cleaning solution in real time. When the detected value is lower than the preset threshold, the controller 16 triggers the alarm system to prompt the staff to replenish the concentrate. The replenished cleaning solution is mixed evenly and then sent back to the cleaning tank 1, forming a complete closed-loop cycle. This achieves efficient recycling of the cleaning solution, reducing production costs and wastewater discharge while ensuring the cleaning effect.

[0028] Reference Figures 4-5An adjustment assembly 15 is provided between the feed roller 2 and the discharge roller 3. The adjustment assembly 15 includes a sliding seat 156, which is located between the feed roller 2 and the discharge roller 3. A tension roller 151 is rotatably connected to the inner side of the sliding seat 156, and a slider 152 is fixedly connected to the outer side of the sliding seat 156. A vertical plate 153 is fixedly connected to the cleaning tank 1. A spring 155 is fixedly connected to the lower side of the sliding seat 156. The side of the spring 155 away from the sliding seat 156 is fixedly connected to the cleaning tank 1. A limiting groove 154 is opened inside the vertical plate 153. The slider 152 is slidably connected inside the limiting groove 154. The tension roller 151 is slidably connected to the upper side of the cleaning tank 1.

[0029] Specifically, when the tension of the anode foil fluctuates, the tension roller 151 slides vertically within the limiting groove 154 of the vertical plate 153 via the sliders 152 on both sides of the sliding seat 156, simultaneously compressing or stretching the spring 155 to achieve tension buffering. The preload of the spring 155 can be precisely adjusted according to the actual thickness of the anode foil through a mechanical adjustment mechanism to ensure stable tension support under various working conditions. In this way, real-time dynamic adjustment of the anode foil tension is achieved, avoiding quality problems such as wrinkles and tears caused by sudden tension changes, and ensuring the integrity and surface quality of the anode foil during the cleaning process.

[0030] Working principle: When using this device, the anode foil enters the cleaning tank 1 through the feed roller 2 and forms an S-shaped path under the guidance of the guide roller 4. The discharge roller 3 is located to the right of the feed roller 2 to ensure horizontal output. When the foil tension changes, the tension roller 151 slides in the limiting groove 154 of the vertical plate 153 through the sliders 152 on both sides of the sliding seat 156. The compression or tension spring 155 achieves buffering. The preload of the spring 155 can be adjusted according to the foil thickness to avoid sudden tension changes that may cause wrinkles or tears.

[0031] Pump 6 delivers the cleaning solution from storage tank 5 to spray frame 13, where it is sprayed at high pressure onto the upper and lower surfaces of the anode foil through nozzle 14. The used cleaning solution flows into filter tank 7, where it first passes through lower filter screen 8 to intercept particulate impurities, and then through upper activated carbon adsorption layer 9 to remove organic matter. Circulation pump 10 delivers the filtered liquid to replenishment tank 11. Concentration sensor 12 monitors the concentration in real time; when the concentration falls below a threshold, controller 16 allows personnel to replenish concentrated solution to maintain the cleaning effect. The regenerated cleaning solution is returned to cleaning tank 1, forming a closed-loop cycle.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
