Description

Infrared heating tin refining equipment Technical Field The utility model relates to the technical field of nonferrous metal smelting equipment, in particular to infrared heating tin refining equipment. Background In the same industry, the heating modes of the tin refining pot mostly adopt modes of coal burning, coal gas, natural gas, electric heating, diesel oil and the like. In the metallurgical industry, the heating of a tin heating pot at the present stage is carried out by using a natural gas heating technology, and in the heating process, the fuel consumption and the air quantity are regulated by the opening of a valve, so that the temperature control of metal liquid in the pot body is realized. However, this conventional heating method has the following problems: 1. The traditional heating mode controls the temperature by adjusting the fuel consumption and the air quantity, but the mode is difficult to realize accurate temperature control, and has low heat utilization rate, high energy consumption and high carbon emission. 2. The traditional heating mode easily causes that the pot body is heated unevenly, and the heated part is easy to carbonize due to strong heat exchange, thereby reducing the service life of the pot body. 3. In the heating process, the hearth is required to be kept at negative pressure, toxic and harmful gases are generated in the combustion process and are timely discharged, and a large amount of energy consumption is lost in the process, and safety and environmental protection facilities are also required to be matched. Therefore, research on infrared heating tin refining equipment with accurate temperature control and uniform heating of a pot body is a problem to be solved by those skilled in the art. Disclosure of utility model In view of the above, the utility model provides infrared heating tin refining equipment with accurate temperature control and uniform heating of the pot body. In order to achieve the above purpose, the present utility model adopts the following technical scheme: An infrared heated tin refining apparatus comprising: The stove body shell is provided with a fireproof lining at the bottom surface and the inner wall of the inner cavity of the stove body shell, and the fireproof lining forms a stove chamber; the cone frustum is arranged at the bottom of the hearth; the pot body is placed in the hearth from the top opening of the cooker body shell, and the bottom of the pot body is arranged at the top end of the cone frustum; The infrared heaters are positioned at the bottom of the hearth and are uniformly distributed along the side wall of the hearth; The thermocouple is arranged in the pot body; And the control cabinet is connected with the thermocouple and the infrared heater. The technical scheme has the advantages that the tin liquor temperature can be accurately controlled, different process requirements are met, the infrared heaters are uniformly distributed along the side wall of the hearth, the heating area of the pot body is large and uniform, the service life of the pot body is prolonged, the infrared heating mode is noiseless and free of exhaust gas, energy consumption loss is reduced, and additional safety and environmental protection facilities are not needed.
