Description

Technical Field

[0001] This utility model belongs to the field of aluminum foil corrosive acid technology, and in particular relates to an aluminum foil corrosive acid recycling device. Background Technology

[0002] Aluminum foil etching acid is a specific acid system used in aluminum foil production to chemically etch and expand the pores on the surface of aluminum foil. It is essentially a "functional acid" whose core function is to etch a uniform and dense porous structure on the surface of aluminum foil. These porous structures can significantly increase the specific surface area of ​​aluminum foil, meeting the requirements of electrolytic capacitors.

[0003] Currently, in waste acid recovery equipment, regenerated acid needs to be manually transferred to a separate compounding tank. After the acid concentration is manually sampled and tested, fresh acid and additives are manually added. This process is time-consuming and labor-intensive, and is prone to instability of electrolyte composition due to human error. In addition, most equipment does not have a pretreatment unit, and suspended impurities in the waste acid directly enter the separation component, which can easily cause component blockage and require frequent shutdowns for cleaning, resulting in reduced recovery efficiency.

[0004] Therefore, we propose an aluminum foil corrosion acid recovery and utilization device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the prior art, such as unstable electrolyte composition due to human operation errors, and the fact that most equipment does not have a pretreatment unit, allowing suspended impurities in waste acid to directly enter the separation component, which easily causes component blockage, requires frequent shutdowns for cleaning, and leads to reduced recovery efficiency. Therefore, this invention proposes an aluminum foil corrosion acid recovery and utilization device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A device for recycling aluminum foil corroding acid includes a waste acid storage tank.

A first water pump is fixedly connected to the upper surface of the waste acid storage tank, and a liquid storage pipe is fixedly connected to the output end of the first water pump. Several identical spray nozzles are fixedly connected to the outer surface of the liquid storage pipe. A second water pump is fixedly connected to the upper surface of the water storage tank, and a water storage pipe is fixedly connected to the output end of the second water pump. Several identical water spray nozzles are fixedly connected to the outer surface of the water storage pipe. A stepper motor is fixedly connected to the upper surface of the mixing tank.

[0007] Preferably, a reinforcing frame is fixedly connected to the outer surface of the control panel, and the right side of the reinforcing frame is fixedly connected to the left side of the waste acid storage tank.

[0008] Preferably, a fixing frame is fixedly connected to the outer surface of the first water pump, and the bottom surface of the fixing frame is fixedly connected to the upper surface of the waste acid storage tank.

[0009] Preferably, a support frame is fixedly connected to the outer surface of the second water pump, and the bottom surface of the support frame is fixedly connected to the upper surface of the water storage tank.

[0010] Preferably, a protective box is fixedly connected to the outer surface of the stepper motor, and the bottom surface of the protective box is fixedly connected to the upper surface of the compound box.

[0011] Preferably, a pull handle is fixedly connected to the outer surface of the movable frame, and two limiting frames are fixedly connected to the outer surface of the pull handle. The outer surface of each limiting frame is fixedly connected to the outer surface of the movable frame. A first discharge valve is fixedly connected to the outer surface of the separation box, and a second discharge valve is fixedly connected to the left side of the compounding box.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. By setting up a filter screen, suspended impurities in the waste acid can be intercepted before entering the waste acid storage tank, preventing impurities from entering the membrane body of the separation tank with the waste acid. This solves the problem of frequent shutdowns for cleaning of existing equipment due to impurities clogging the membrane module, reduces downtime, and significantly improves the continuity and efficiency of the recycling process. 2. By setting up an automated conveying structure with a first and a second conveying pump, fresh medicine and separated pure acid can be directly conveyed to the compounding tank, replacing manual transfer and avoiding spillage and inefficiency problems caused by manual operation. The controller can accurately control the conveying volume of the two pumps according to preset process parameters, avoiding concentration deviations caused by manual sampling and addition. At the same time, the stepper motor in the compounding tank drives the stirring rod to rotate, which can fully mix the medicine and acid, further ensuring the uniformity of the regenerated acid components and meeting the "functional" requirements of the acid system for aluminum foil corrosion.

The output end of the second delivery pump 29 is fixedly connected to the outer surface of the compounding box 13. A movable frame 8 is snapped into the inside of the separation box 7.

[0020] Several identical membrane bodies 22 are fixedly connected to the inner wall of the movable frame 8. The upper surface of the waste acid storage tank 1 is fixedly connected to the feed pipe 4. The inner wall of the feed pipe 4 is fixedly connected to the filter screen 5. The outer surface of the movable frame 8 is fixedly connected to the pull handle 23.

[0021] The working principle of this utility model is as follows: When in use, the waste acid generated by the corrosion of aluminum foil is first introduced through the feed pipe 4. When the waste acid flows through the feed pipe 4, the filter screen 5 directly intercepts the suspended impurities in the waste acid, preventing the impurities from entering the subsequent separation stage with the waste acid. The pretreated waste acid is temporarily stored in the waste acid storage tank 1. After the waste acid in the waste acid storage tank 1 reaches the preset liquid level, the second delivery pump 29 is started to transport the pretreated waste acid in the waste acid storage tank 1 to the separation tank 7. The membrane body 22 in the separation tank 7 performs deep filtration on the waste acid, intercepting the fine impurities that are not intercepted by the filter screen 5. The pure acid liquid permeates to the other side of the membrane body 22 and collects at the bottom of the separation tank 7. If a decrease in separation efficiency is detected, such as an increase in the pressure of the second delivery pump 29, the movable frame 8 can be pulled out from the separation tank 7 by pulling the handle 23, and a new membrane body 22 can be replaced and reinstalled. There is no need to shut down and disassemble the entire equipment. The first delivery pump 28 is started to transport the fresh acid and additives in the drug storage tank 6 to the compounding tank 13. At the same time, the second delivery pump 29 is started to transport the pure acid in the separation tank 7 to the compounding tank 13 according to the preset ratio. The stepper motor 25 in the upper surface protection box 11 of the compounding tank 13 is started. The output end of the stepper motor 25 drives the stirring rod 27 to rotate at high speed through the bearing 26, so that the fresh drug and pure acid are fully mixed. The control panel 2 monitors the acid concentration in the compounding tank 13 in real time and provides feedback through the built-in sensor. After the concentration reaches the requirements of the aluminum foil etching process, the second discharge valve 10 on the left side of the compounding tank 13 is opened to transport the qualified regenerated acid to the aluminum foil etching production line.
