Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically a flow and conductivity stabilization system for electrolytic foil. Background Technology

[0002] In modern industrial production, especially in the field of electronic component manufacturing, such as the production of aluminum electrolytic capacitors, the quality of the formed foil directly affects the performance of the final product. The forming foil processing involves multiple chemical reactions that need to be carried out under precise control to ensure product consistency and reliability. Among these, the flow rate and conductivity of the mixing bath are two key parameters, crucial for maintaining a uniform chemical reaction on the surface of the formed foil.

[0003] In traditional electrolytic foil processing systems, the flow rate and conductivity control of the blending bath solution typically relies on manual operation or simple mechanical devices, which has several drawbacks. First, manual monitoring cannot achieve continuous, real-time data acquisition, resulting in low control accuracy and susceptibility to fluctuations. Second, traditional methods struggle to quickly respond to environmental changes (such as temperature and humidity) affecting the properties of the blending bath solution, thus impacting product quality. Furthermore, the lack of effective automated control methods leads to high system maintenance costs and low operating efficiency. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a flow and conductivity stabilization system for electroforming foil, which can ensure the stability of the flow and conductivity of the mixing tank solution, thereby improving the processing quality and production efficiency of electroforming foil.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a flow conductivity stabilization system for electrolytic foil, including a mixing tank, a circulation pipeline provided on the mixing tank, the inlet end of the circulation pipeline being connected to the bottom of the mixing tank, the outlet end of the circulation pipeline extending from the top of the mixing tank, and multiple branch pipes connected to different machines provided on the circulation pipeline;

[0006] The circulation pipeline is equipped with an online conductivity electrode and a circulation pump. The online conductivity electrode is connected to an online conductivity meter, and the online conductivity meter is connected to a PLC controller.

[0007] The mixing tank is equipped with a platinum resistance thermometer, which is also connected to the PLC controller.

[0008] In a preferred embodiment, a high-concentration raw material tank is also included, and a high-concentration raw material pipeline extending into the high-concentration raw material tank is provided on the high-concentration raw material pipeline, and a peristaltic pump is provided on the high-concentration raw material pipeline.

[0009] In a preferred embodiment, the top of the mixing tank is equipped with a pure water pipeline, and the pure water pipeline is equipped with a fully automatic liquid level control valve.

[0010] In a preferred embodiment, the peristaltic pump and the fully automatic liquid level control valve are connected to a PLC controller.

[0011] The flow conductivity stabilization system for electrolytic foil provided by this utility model, by adopting the above-described structure, has the following beneficial effects:

[0012] (1) Through real-time monitoring by online conductivity electrodes and online conductivity meters, combined with intelligent control by a PLC controller, the conductivity of the mixing bath can be quickly and accurately detected and adjusted to ensure that it is always within the set range. This not only improves the consistency and reliability of the electrolytic foil processing, but also reduces product quality problems caused by conductivity fluctuations;

[0013] (2) Through the fully automatic liquid level control valve, the system can automatically adjust the amount of pure water added according to the changes in the liquid level in the mixing tank, and maintain the stability of the liquid level. This not only reduces the need for manual intervention, but also avoids production interruptions caused by liquid level fluctuations, and improves production efficiency;

[0014] (3) The platinum resistance thermometer can monitor the temperature in the mixing tank in real time and transmit the data to the PLC controller. The PLC controls the peristaltic pump to drive the raw materials in the high-concentration raw material pipeline into the mixing tank, ensuring that the mixing tank liquid works under the best temperature conditions, which further improves the quality of the electrolytic foil treatment.

[0018] like Figure 1 In the present invention, a flow conductivity stabilization system for electrolytic foil includes a mixing tank 1, wherein a circulation pipe 10 is provided on the mixing tank 1, the inlet of the circulation pipe 10 is connected to the bottom of the mixing tank 1, the outlet of the circulation pipe 10 extends into the top of the mixing tank 1, and multiple branch pipes connected to different machines are provided on the circulation pipe 10.

[0019] The circulation pipeline 10 is equipped with an online conductivity electrode 3 and a circulation pump 4. The online conductivity electrode 3 is connected to an online conductivity meter 6, and the online conductivity meter 6 is connected to a PLC controller 2.

[0020] The mixing tank 1 is equipped with a platinum resistance thermometer 5, which is also connected to the PLC controller 2.

[0021] In a preferred embodiment, a high-concentration raw material tank 9 is also included, and a high-concentration raw material pipeline 11 extending into the high-concentration raw material tank 9 is provided on the high-concentration raw material tank 9. A peristaltic pump 7 is provided on the high-concentration raw material pipeline 11.

[0022] In a preferred embodiment, the top of the mixing tank 1 is provided with a pure water pipeline 12, and the pure water pipeline 12 is provided with a fully automatic liquid level control valve 8.

[0023] In a preferred embodiment, the peristaltic pump 7 and the fully automatic liquid level control valve 8 are connected to the PLC controller 2.

[0024] This utility model provides a flow and conductivity stabilization system for chemically formed foil. By integrating a mixing tank liquid circulation device, an automatic water addition device, and an online conductivity control system, it achieves precise control of the flow rate and conductivity of the mixing tank liquid. The following is a detailed description of the system's working principle:

[0025] The inlet of the circulation pipe 10 is connected to the bottom of the mixing tank 1, and the outlet extends from the top of the mixing tank 1. The purpose of this design is to ensure that the liquid in the mixing tank can be drawn out from the bottom, circulated, and then evenly returned to the mixing tank 1, thus ensuring the circulation of the liquid in the tank. The circulation pipe 10 is equipped with multiple branch pipes connected to different machines to ensure that each machine can obtain a uniform supply of liquid in the tank.

[0026] The circulating pump 4 is installed on the circulating pipeline 10 and is responsible for pumping the liquid from the bottom of the mixing tank 1 to the top and distributing it to each machine through the branch pipe. The working status of the circulating pump 4 is controlled by the PLC controller 2 as needed.

[0027] The online conductivity electrode 3 is installed on the circulation pipeline 10 to monitor the conductivity of the mixing tank liquid in real time. The conductivity electrode 3 transmits the detected conductivity data to the online conductivity meter 6. The online conductivity meter 6 receives the conductivity data from the online conductivity electrode 3 and transmits it to the PLC controller 2.

[0028] The PLC controller 2 analyzes the data transmitted by the online conductivity meter 6 in real time according to the preset conductivity range. If the conductivity is detected to be lower than the set value, the PLC controller 2 will issue a command to start the peristaltic pump 7 to add high-concentration raw materials from the high-concentration raw material tank 9 to the mixing tank 1 through the high-concentration raw material pipeline 11 until the conductivity is restored to the set range.

[0029] The high-concentration raw material tank 9 stores a high-concentration raw material solution. The high-concentration raw material pipeline 11 leads out from the high-concentration raw material tank 9 and transports the high-concentration raw material to the mixing tank 1 through the peristaltic pump 7. The peristaltic pump 7 is installed on the high-concentration raw material pipeline 11 and is controlled by the PLC controller 2. When it is necessary to adjust the conductivity, the peristaltic pump 7 is started to add the high-concentration raw material to the mixing tank 1.

[0030] Pure water pipeline 12 is connected from the top of mixing tank 1 and is used to replenish pure water into mixing tank 1. Fully automatic liquid level control valve 8 is installed on pure water pipeline 12 and is controlled by PLC controller 2. When the liquid level in mixing tank 1 is lower than the set value, fully automatic liquid level control valve 8 automatically opens to replenish pure water; when the liquid level reaches the set value, the valve closes and stops adding water.

[0031] Platinum resistance thermometer 5 is installed in the mixing tank 1 to monitor the temperature of the liquid in the mixing tank in real time. Platinum resistance thermometer 5 transmits temperature data to PLC controller 2. PLC controller 2 analyzes the temperature data transmitted by platinum resistance thermometer 5 in real time according to the preset temperature range. If the temperature exceeds the set range, PLC controller 2 can take corresponding control measures, such as starting cooling (by installing cooling coils inside or outside the mixing tank) or heating (by setting electric heating tubes in the mixing tank) equipment to ensure that the liquid in the mixing tank works under the optimal temperature conditions.
