Key Features of Industrial Electrolyte Mixer for Solvent Extraction For Metallurgical Industry
______ Top brands Agitator Manufacturers in China For more than 40 Years.
An electrolyte agitator is essentially a device specifically designed to mix electrolyte solutions. It combines the mixing function of a normal mixer with special consideration of the characteristics of the electrolyte solution (such as conductivity, possible corrosiveness, the need to maintain uniformity to ensure electrochemical reaction efficiency, etc.).
Core purpose:
Even mixing:
Ensure that the solutes (salts, acids, bases, etc.) in the electrolyte solution are completely dissolved and evenly distributed to avoid local concentrations that are too high or too low.
Prevent precipitation: Continuous stirring can prevent solid particles from settling in the solution or agglomerating at the bottom of the container/electrode surface, which is essential for maintaining the conductivity of the solution and the stability of the reaction.
Promote mass transfer:
In scenarios involving electrochemical reactions (such as electrolysis, electroplating, battery charging and discharging, and electrosynthesis), stirring can accelerate the transfer of reactants to the electrode surface and the departure of products from the electrode surface, thereby increasing the reaction rate and efficiency.
Temperature homogenization:
Helps disperse the heat in the solution to make the temperature of the entire solution system more uniform, especially when the electrochemical reaction may generate heat or require temperature control.
Avoid concentration polarization:
In an electrochemical system, the ion concentration near the electrode will change due to the reaction, forming a concentration gradient (concentration polarization), which hinders the reaction. Stirring can effectively reduce this polarization phenomenon.
Common types:
Magnetic Drive Agitator:
Most commonly used. A rotating magnet is placed under the container, and a magnetic stirrer wrapped in polytetrafluoroethylene is placed in the container. The advantages are good sealing, no external rotating parts invading the solution, easy sealing, suitable for small-scale laboratory applications and occasions where contamination needs to be avoided. The stirring intensity is usually medium.
Vertical Mixers:
The motor is above the container, and the stirring shaft and blades are extended into the solution for stirring. The advantages are strong stirring force and high controllability, suitable for medium and large containers, high viscosity solutions or occasions where strong mixing is required. It is necessary to select corrosion-resistant stirring paddles (such as stainless steel, titanium, Hastelloy or coated) and well-sealed stirring shaft sleeves.
Mechanical mixers (fixed):
Similar to the overhead type, but usually fixed on the reaction tank, used for large electrolytic cells, electroplating tanks, etc. in industrial production.
Gas bubbling stirring: Inert gas (such as nitrogen, argon) is introduced into the bottom of the solution, and the rising process of bubbles drives the solution to flow. It is often used in occasions where oxidation needs to be avoided or deoxygenation is required, and the stirring intensity is relatively mild.
Circulation pump stirring:
The solution is pumped out from one end of the tank through an external pump and then pumped back from the other end to form a circulation flow. Suitable for very large tanks or when it needs to be used in conjunction with other equipment (such as heat exchangers).
Key application areas:
Electrochemical research: Ensure uniform solution in the electrolytic cell when conducting electrolysis, battery testing, corrosion research, electroanalytical chemistry and other experiments in the laboratory.
Electroplating and surface treatment: Electroplating tanks, anodizing tanks, etc., ensure uniform distribution of plating solution components, obtain uniform coatings, and prevent impurities from depositing on the surface of the workpiece.
Battery manufacturing and R&D: Stirring and mixing when preparing electrolytes for lithium-ion batteries, flow batteries, etc.; maintaining electrolyte uniformity during battery testing.
Electrolytic industry: large electrolytic cells such as chlor-alkali industry (electrolysis of salt water), electrolysis of water to produce hydrogen/oxygen, and electrolytic metallurgy (such as electrolytic refining of copper and aluminum).
Chemical synthesis: Synthesis reactions involving electrochemical steps.
Wastewater treatment: When treating wastewater by electrochemical oxidation/reduction.
Key factors to consider when selecting an electrolyte stirrer:
Solution properties: Corrosiveness (determines the material selection of the stirring paddle, stirrer, and sealing material - commonly used glass, polytetrafluoroethylene, ceramics, corrosion-resistant metals/alloys), viscosity, density, and whether it contains solid particles.
Stirring intensity requirements: Gentle mixing or strong shear or high mass transfer rate?
Container size and shape: Determines the power of the stirrer and the size of the stirring paddle/stirrer.
Operating environment: laboratory, pilot or industrial scale? Is sealing, temperature control, and atmosphere control required?
Electrochemical system requirements: Is it close to the electrode? Is it necessary to avoid introducing metal ion contamination (magnetic stirrers or PTFE stirring paddles are better in this case)?
Safety: Ensure that motors, wires, etc. are away from the solution to prevent leakage; highly corrosive or flammable and explosive solutions require special protection.
In summary
Electrolyte stirrers are indispensable tools for handling electrolyte solutions. They maintain the uniformity, stability, and reactivity of the solution by mechanical or physical means, and are widely used in many electrochemical related fields from laboratory research to industrial production. Selecting the right type and material is crucial to the success of an experiment or production.
