Abstract

The invention relates to the field of filter press equipment, especially to a vacuum screw filter press with a heat transfer function. The vacuum screw filter press comprises a first pipeline, a second pipeline, a feeding device and a negative pressure pipe, wherein the first pipeline is horizontally arranged in the second pipeline; a heat source cavity for providing heat is formed between the first pipeline and the second pipeline, and heat is transferred via a heat source to increase the evaporation amount of a material; the feeding device includes a feeding drum arranged above the second pipeline; heat source cavities for providing heat are formed among a feeding pipe, the first pipeline and the second pipeline, and heat can be transferred via the heat source in virtue of the setting of the heat source cavities so as to increase the evaporation amount of the material and improve press filtration effect; the negative pressure pipe communicates with the first pipeline, a negative pressure fan is connected with one end of the negative pressure pipe, and a suction force is generated by the negative pressure fan to further accelerate the evaporation amount of liquid in the material; and a screw blade is arranged, and a screw extrusion manner is adopted to realize more smooth forward transport of the material.

Description

technical field [0001] The invention relates to the field of filter press equipment, in particular to a vacuum screw filter press with heat transfer function. Background technique [0002] Vacuum filter press is a device that realizes solid-liquid separation with vacuum negative pressure as the driving force. It can be widely used in solid-liquid separation in metallurgy, mining, chemical industry, papermaking, food, pharmaceutical, environmental protection and other fields. However, the existing vacuum filter press only uses two filter cloths to squeeze up and down, and relies on the pressure generated by the two filter cloths to filter the feed material. This kind of filtering effect is not good, and the material after pressure filtering often still contains a lot of Therefore, there is currently a lack of a vacuum screw filter press with good filtering effect. SUMMARY OF THE INVENTION [0003] (1) Technical problems to be solved [0004] Solve the problem that the exi...
