Description

technical field [0001] The invention relates to a controllable heating type vacuum filter press solid-liquid separation device, which belongs to the technical field of chemical analysis experiment equipment. Background technique [0002] The process of separating solid and liquid is solid-liquid separation, which completely separates the solid and liquid phases to obtain their respective pure components. For the current metallurgical chemical experiments, the materials that need to be separated from solid and liquid generally have a high temperature, and the temperature drops suddenly during the separation, resulting in other reactions, such as the hydrolysis of iron, the formation of silica gel, and the occurrence of remelting and other phenomena, which affect the solid state. The effect of liquid separation. In order to achieve the purpose of suction filtration, a vacuum pump or a filter press is generally used. The traditional solid-liquid separation device does not add ...
