Description

Technical Field

[0001] This utility model relates to the technical field of chemical nickel solution preparation equipment, specifically a pump-in quantitative metering device for automated production of chemical nickel solution. Background Technology

[0002] Chemical nickel plating solutions are high-performance plating solutions widely used in the electroplating industry. They are typically used to deposit nickel coatings on metal surfaces to enhance their corrosion resistance, hardness, and wear resistance. Precise control of the solution ratio, concentration, and additives is crucial in the preparation of chemical nickel plating solutions. The preparation of the solution involves multiple chemical components, many of which are highly corrosive; therefore, the precise metering and preparation of the solution require extremely strict control. To ensure the stability, performance consistency, and high efficiency of chemical nickel plating solutions, the application of automated control systems in solution production is receiving increasing attention.

[0003] Traditional nickel chemical production typically relies on manual operation for the quantitative metering and delivery of the concentrate, which has certain drawbacks:

[0004] 1. Instability of manual operation: Traditional manual metering is easily affected by factors such as operator experience and operating environment, resulting in inaccurate drug metering and affecting the quality and production stability of the drug.

[0005] 2. Poor safety: The preparation of chemical nickel solution involves a variety of highly corrosive liquids. Traditional manual operation is prone to safety accidents such as leakage and misoperation, which poses a threat to personnel safety.

[0006] 3. Low production efficiency: Manual operation is not only inefficient, but also prone to errors, affecting overall production efficiency, especially in large-scale continuous production, which cannot meet the needs of modern production.

[0007] 4. Environmental pollution issues: In traditional manual operation, improper handling often causes splashing and leakage of the liquid medicine, which not only wastes raw materials, but may also pollute the production environment.

[0008] With the rapid development of automation technology, the adoption of automated metering equipment has gradually become an important development trend in the production of electroless nickel solutions. Automated equipment can monitor the flow rate, level, and ratio of the solution in real time through precise sensors and control systems, achieving accurate and stable metering and delivery, greatly improving production efficiency, ensuring solution quality, reducing manual intervention, and effectively avoiding problems such as solution leakage and splashing, thereby ensuring production safety and environmental protection.

[0009] Currently, some liquid metering devices are used in chemical production, but most of them have the following shortcomings:

[0010] 1. Insufficient measurement accuracy, especially when dealing with complex chemical reaction systems, may lead to measurement deviations.

[0011] 2. The equipment is not intelligent enough and lacks real-time feedback and self-adjustment mechanisms, which can easily lead to the accumulation of errors in the production process.

[0012] 3. The lack of an efficient liquid reflux and reprocessing system leads to waste of raw materials and inefficient use of resources.

[0013] Therefore, designing a device with high-precision metering, automated control, liquid reflux and reuse functions has become an urgent need in the automated production of electroless nickel solutions. Utility Model Content

If the measured data differs significantly from the set value, the raw liquid is returned to the storage tank through the return pipe and the return pump. At the same time, the delivery pump is adjusted accordingly. If the measured data does not differ significantly from the set value, the filling pump is started.
