Intelligent continuous solidification separator for crude tin purification and crystallization method

Abstract

The invention discloses an intelligent continuous solidification separator for crude tin purification and a crystallization method. The separator comprises a separator support, a motor, a rotating shaft, a U-shaped crystallization tank, a spiral blade, a modular heating body, a bottom patch type temperature sensor, a shaft sleeve type temperature sensor, a blade patch type temperature sensor, a high-definition infrared temperature sensor, an infrared temperature measurement system support, a speed sensor, a material melting pot, a crystal pot, a melt pot and a 5G wireless transceiver. The temperature of the solidification separator is monitored and controlled in real time through a multi-dimensional temperature measurement system and a modular heating system, the rotating speed of a solidification separator is controlled in real time through an intelligent speed regulation system, meanwhile, the high-temperature-resistant 5G wireless transceiver is adopted for real-time online transmission of data, the data is fed back to a mobile terminal after being processed by the server, and the mobile terminal can also directly regulate and control the separator in real time.

Description

technical field [0001] The invention belongs to the technical field of pyrometallurgy of nonferrous metals, and in particular relates to an intelligent continuous solidification separator and a crystallization method for purifying crude tin. Background technique [0002] Purification of crude tin by crystallization separation is to put the crude tin containing impurities such as lead and bismuth into a certain temperature gradient. In the process of heating and cooling, crystals and liquids will be produced in different temperature ranges, and the two flow countercurrently. Impurities such as bismuth and bismuth are enriched at the end of the liquid phase with low temperature, and the solid phase with high temperature is purified crude tin crystals. The electrothermal continuous crystallizer developed in my country in 1975 is a refining equipment that uses this method to remove lead and bismuth from crude tin. . Since the equipment was put into production, it is still at the ...

Problems solved by technology

The three-stage heating power ratio mentioned in this patent cannot ensure that the actual temperature of each stage is consistent with the theoretical temperature, so the temperature of each stage cannot be precisely controlled, and the quality of the final product may not meet the national standard. A high-efficiency electrothermal continuous crystallizer is disclosed in the new model, which is characterized in that a large-diameter and a small-diameter spiral stirrer are arranged on the rotating shaft, which improves the current electrothermal continuous crystallizer equipment in tin smelters, but the temperature range of the crystallizer is not enough , there are doubts about whether the product quality of the final product meets the national standard

In the utility model with the publication number CN206069975U, an electrothermal continuous crystallizer for processing crude tin is mentioned, which is characterized in that the solder discharge port is equipped with an electric heating element, which replaces the original way of diesel heating and discharging solder, and adopts six stages Type heating, there is heat conduction between the heating sections of this patent, and a uniform temperature gradient cannot be guaranteed
