Description

Technical Field

[0001] This utility model relates to battery processing equipment, and more particularly to an electrolytic device for electrolyzing manganese dioxide. Background Technology

[0002] With the rapid development of the battery industry, especially the advent of the Internet of Things era, not only are there increasingly higher energy requirements for rechargeable batteries, but also for primary batteries such as alkaline zinc-manganese batteries, which require higher capacity and higher rate of operation. It is expected that as the market gradually drives development, lead-acid batteries will be phased out, and electrolytic manganese dioxide for new batteries will experience rapid growth, driving the overall development of the electrolytic manganese dioxide product market.

[0003] However, current equipment for electrolytic manganese dioxide production is polarized: laboratory equipment produces only grams of product per electrolysis cycle, and electrolysis parameters are mostly manually controlled, resulting in significant differences from actual production line processes and making it difficult to reproduce experimental results on the production line; production line equipment produces hundreds of kilograms to tons of product per electrolysis cycle, also requiring manual monitoring of key parameters during the electrolysis process and subsequent manual adjustments and optimizations. Furthermore, the instability of the electrolytic cell due to changes in electrolyte volume further restricts the production efficiency and product stability of electrolytic manganese dioxide. Therefore, there is an urgent need to develop equipment capable of automatically controlling the electrolysis process and monitoring the electrolyte state and temperature in real time. Utility Model Content

[0004] The purpose of this invention is to provide an electrolysis device for electrolyzing manganese dioxide.

[0005] The technical solution to achieve the purpose of this utility model is: an electrolytic device for electrolyzing manganese dioxide, comprising an electrolytic cell, a replenishment tank and a waste liquid collection tank arranged below the electrolytic cell, the replenishment tank being connected to the electrolytic cell via a replenishment pipe, and a constant flow pump being installed on the replenishment pipe; an overflow port being arranged on the side of the electrolytic cell near the upper end, the overflow port being connected to the waste liquid collection tank via an overflow pipe; a pH electrode being installed inside the electrolytic cell, and both the constant flow pump and the pH electrode being communicatively connected to a controller.

[0006] Furthermore, the electrolytic cell is equipped with a level sensor for monitoring the electrolyte level, and the level sensor is communicatively connected to the controller. When the level sensor detects that the electrolyte level in the electrolytic cell is lower than the working level, the system issues a power-off command, and the electrolysis equipment stops working.

[0007] Furthermore, the bottom of the replenishment tank and the waste liquid collection tank is provided with a gap for the forklift arm to be inserted so that the forklift can move the tank out.

[0008] Furthermore, the electrolytic cell is equipped with a temperature sensor to monitor the electrolyte temperature, and a heating device for heating the electrolyte is installed at the bottom of the electrolytic cell. Both the temperature sensor and the heating device are communicatively connected to the controller. Through the automatic temperature control function of the heating system, precise temperature control during the electrolysis process is achieved, solving the problem of insufficient temperature control accuracy in existing technologies and ensuring the stability of the electrolysis process and product quality.

[0009] The electrolytic equipment for electrolyzing manganese dioxide developed in this invention features a compact structure and achieves automated control of the electrolysis process, freeing up manpower and significantly reducing experimental costs. The pH electrode collects the pH value of the electrolyte in real time and adjusts the electrolyte replenishment based on fluctuations between the real-time pH value and the set value, effectively improving the purity and quality of the electrolyte and avoiding fluctuations during electrolysis. The combined design of the constant flow pump and replenishment tank enables continuous electrolyte replenishment, effectively improving electrolysis efficiency. Furthermore, the overflow port design of the electrolytic cell ensures a constant electrolyte volume within the cell, achieving stability in the electrolysis process and solving the problem of unstable operating conditions in the electrolytic cell.

Detailed Implementation

[0011] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0012] like Figure 1 and Figure 2 As shown, an electrolytic device for electrolyzing manganese dioxide includes an electrolytic cell 1. A temperature sensor 2 is installed inside the electrolytic cell 1 to monitor the temperature of the electrolyte. A heating device 3 is installed at the bottom of the electrolytic cell 1 to heat the electrolyte. A replenishment tank 4 and a waste liquid collection tank 5 are located below the electrolytic cell 1. The replenishment tank 4 is connected to the electrolytic cell 1 via a replenishment pipe 6, and a constant flow pump 61 is installed on the replenishment pipe 6. An overflow port 12 is located on the side of the electrolytic cell 1 near its upper end 11, and the overflow port 12 is connected to the waste liquid collection tank 5 via an overflow pipe 7. A pH electrode 8 and a level sensor 9 for monitoring the electrolyte level are also installed inside the electrolytic cell 1. The constant flow pump 61, the pH electrode 8, the level sensor 9, the heating device 3, and the temperature sensor 2 are all communicatively connected to a controller 10.

[0013] The workflow of the electrolytic equipment for electrolyzing manganese dioxide implemented in this embodiment is as follows: The prepared electrolyte (a mixed solution of sulfuric acid and manganese sulfate, plus electrolyte additives; sulfuric acid concentration 40-100 g / L, manganese sulfate concentration 50-100 g / L) is poured into the electrolytic cell. The electrolytic current / voltage, electrolytic temperature, electrolyte pH, and electrolyte replenishment rate are then set on the controller. After electrolysis begins, a constant flow pump continuously replenishes the electrolyte. A pH electrode periodically collects the real-time pH value of the electrolyte. The pH electrode is electrically connected to a pH analysis and control instrument. When the real-time pH value fluctuates from the set value, it is fed back to the controller. The controller then issues instructions based on the data from the pH electrode to adjust the real-time replenishment rate of the constant flow pump. The electrolytic cell is equipped with an overflow port to ensure a constant electrolyte volume throughout the cell. During electrolysis, electrolytic manganese dioxide is deposited on the anode titanium plate. After electrolysis, the electrolytic manganese dioxide is peeled off the titanium plate, crushed, washed, and ground to obtain electrolytic manganese dioxide powder. This electrolysis equipment automatically controls the electrolyte temperature and pH value within the electrolytic cell to maintain a constant level, ensuring the stability of the entire electrolysis system and improving electrolysis efficiency and product quality. Based on this, by configuring a suitable number of electrodes and a sufficiently large electrolytic cell volume, electrolysis output can reach the kilogram level.

[0014] The controller described in this invention is a PLC controller or an MCU controller, etc. The constant flow pump is a pump device that can output a stable flow rate of liquid. The temperature sensor, liquid level sensor and pH electrode are also existing technologies and will not be described in detail here.

[0015] The temperature sensor is set as needed, and the heating device can be a conventional heating device such as a jacketed heating device or a coil heating device. Through the automatic temperature control function of the heating device, the temperature during the electrolysis process is precisely controlled, which solves the problem of insufficient temperature control accuracy in the prior art and ensures the stability of the electrolysis process and product quality.

[0016] The liquid level sensor is configured as needed. When the liquid level sensor detects that the liquid level of the electrolyte in the electrolytic cell is lower than the working liquid level, the system issues a power-off command, and the electrolysis equipment stops working.

[0017] The bottom of the replenishment tank and waste collection tank is provided with a gap for the forklift arm to be inserted so that the forklift can move the tank out.

[0018] The number of electrolytic cells can be increased according to production / experimental needs. Each electrolytic cell is equipped with a replenishment tank and a constant flow pump to improve working efficiency. The spacing between the anode titanium plate and the anode graphite plate in the electrolytic cell can be adjusted as needed. This is existing technology and will not be described in detail here.

[0019] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent process transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
