Description

TECHNICAL FIELD

[0001] The utility model relates to tungsten smelting equipment field, concretely relates to a tungsten wet smelting complexing agent feeding equipment. BACKGROUND

[0002] Tungsten is widely used in industrial fields due to its outstanding physical and chemical properties. Tungsten is known for its extremely high melting point, excellent hardness and good electrical conductivity, making it an ideal material for manufacturing high-temperature alloys, hard alloys, electronic devices and other products.

[0003] In the extraction and refining process of tungsten, wet smelting is an important process method. In order to produce environmentally friendly, today's production process is improving step by step, for example, in the ammonia-free tungsten smelting process developed by our company, the complexing agent with selective coordination performance to tungsten is used to dissolve tungstic acid from the tungsten calcium material obtained by ore acid leaching, so as to avoid the generation of ammonia-nitrogen waste. In this process, the reaction kettle provides a key environment, so that the complexing agent can react with tungstic acid. The effective operation of the reaction kettle is crucial to the efficiency and product quality of the entire smelting process, as it directly affects the dissolution rate of tungstic acid and the reaction efficiency of the complexing agent.

[0004] However, the existing technology has obvious limitations. In particular, after the complexing agent is added to the reaction kettle, there is a lack of effective real-time monitoring means to obtain the reaction conditions inside the reaction kettle. This lack of monitoring can lead to insufficient reaction, which in turn affects production efficiency and product quality, and may even trigger side reactions, increasing production costs and environmental risks. Therefore, developing a feeding equipment that can monitor the reaction conditions inside the reaction kettle in real time and automatically control the addition of complexing agent is of great significance to improving production efficiency and product quality.

The control mechanism is used to automatically control the delivery of the complexing agent. A detector is provided on the reaction kettle to monitor the dissolution degree of the tungsten calcium material in the reaction kettle in real time. The detector is electrically connected to the control mechanism.

[0007] Further, the control mechanism includes a bracket, an electric push rod, a piston, a piston sleeve, a tee pipe and a check valve; the reaction kettle includes a kettle cover, the top end of the kettle cover is fixedly connected with the bracket, the top of the bracket is fixedly connected with the electric push rod, the telescopic end of the electric push rod is fixedly connected with the piston, the piston is sleeved in the piston sleeve, the left end of the piston sleeve is fixedly connected with the tee pipe, the upper end of the tee pipe is in communication with the bottom end of the discharge port, the lower end of the tee pipe is in communication with the reaction kettle, the upper part in the tee pipe is fixedly connected with the check valve, and the lower part in the tee pipe is also fixedly connected with the check valve.

[0013] Compared with the prior art, the beneficial effects of the present application are as follows:

[0014] 1. Real-time monitoring and automatic quantitative control. The tungsten wet metallurgy complexing agent feeding equipment of the present application realizes real-time monitoring of the dissolution degree of tungsten-calcium material in the reaction kettle by arranging a detector. Through the accurate data provided by the detector and the automatic quantitative control of the control mechanism, it can be determined whether to supplement the complexing agent and how much complexing agent to supplement, so as to ensure that the complexing dissolution reaction of tungsten-calcium material in the reaction kettle is sufficient. This automatic control method not only improves the uniformity and sufficiency of the reaction, but also reduces the uncertainty of manual operation, thereby significantly improving the production efficiency and product quality.

[0015] 2. Automatic stirring to avoid precipitation.

Through regular automatic stirring, the present equipment ensures the uniform distribution and activity of the complexing agent, thereby ensuring the sufficient reaction. This design not only improves the utilization rate of the complexing agent, but also reduces the equipment maintenance and cleaning work caused by precipitation, thereby reducing the production cost.
