Efficient vacuum spiral dehydration and reagent removal equipment

The invention discloses high-efficiency vacuum spiral dehydration and reagent removal equipment, which comprises a dehydration system which comprises a spiral dehydration equipment main body, a main shaft, blades, a main shaft motor and a speed reducer; and a suction filtration system which comprises a water filtering tank, a water filtering plate, a water filtering pipe, a filtrate tank, a vacuumpump, a pneumatic valve and a controller. Compared with traditional spiral dehydration equipment, the efficient vacuum spiral dehydration and reagent removal equipment has the advantages that the discharge concentration is increased from 60-65% to 80-90%; the application range is wider, and the equipment can be suitable for dehydration and reagent removal of reagent-containing, viscious, fine-graded other materials; the dehydration process is simplified, the cyclic utilization rate of reagent-containing liquid is increased, and the wastewater treatment capacity and the production cost are reduced; and the area of a t
