Description

Technical Field

[0001] The utility model relates to the technical field of filter press tanks, in particular to a filter press tank for production. Background Art

[0002] The body of the filter press tank is mostly made of metal. The high thermal conductivity of metal makes it easy for the heat in the tank to be transferred to the outside through the tank wall. In the filter press tank that processes high-temperature chemical raw materials, the tank wall continuously dissipates heat to the surrounding low-temperature environment. Especially in cold weather, heat is lost faster. Although traditional insulation materials have an insulation effect, rock wool is easily affected by moisture, and its insulation performance drops significantly after being damp. In a workshop with high humidity, the insulation effect of the filter press tank wrapped with rock wool will be greatly reduced. At the same time, there are often fewer temperature measurement points in the filter press tank, which leads to a decrease in measurement accuracy and affects its use. Utility Model Content
