Semi-automatic constant-temperature melt trough

Abstract

The invention relates to a semi-automatic constant-temperature melt trough. The semi-automatic constant-temperature melt trough consists of a melt trough (1), a temperature measurement resistor (2), a temperature measurement instrument (3), a pneumatic electromagnetic valve control circuit (4), a pneumatic electromagnetic valve (5), a pneumatic steam valve (6), a manual steam regulating valve (7), an air pipe (8), an air compressor (9), a steam pipeline (10) and small steam pipeline holes (11). When the semi-automatic constant-temperature melt trough is used, if the temperature of liquid in the melt trough (1) is required to be constantly kept within a specific temperature range, the value of low-temperature warning of the temperature measurement instrument (3) is regulated at the value of a lower limit temperature of the temperature range, and the value of high-temperature warning of the temperature measurement instrument (3) is regulated at the value of an lower limit temperature of the temperature range. According to the semi-automatic constant-temperature melt trough, the structure is simple, the effect is obvious, steam heat is adequately adopted, and the temperature is constant in a certain range, so that the volatilization of materials is reduced.

Description

technical field [0001] The invention relates to a molten material tank, in particular to a semi-automatic constant temperature molten material tank. Background technique [0002] In the production process of the factory, the melting tank is often used to dissolve the raw materials. The general heating of the melting tank adopts electric heating and steam heating. The cost of electric heating is high, so many factories use steam heating to save energy and production. Cost, the ordinary steam heating melt tank has no temperature control device, and the steam valve will not be closed during production, which will not only cause waste of steam, but also cause material volatilization due to excessive temperature. Contents of the invention [0003] The purpose of the present invention is to provide a simple and convenient semi-automatic constant temperature melting tank, which can make full use of steam heat and keep the temperature constant within a certain range, thus reducing...
