Fixed belt type vacuum extrusion filter

The utility model discloses a fixed belt type vacuum extrusion filter, which belongs to the field of solid-liquid separation machinery and comprises a rack and a filter belt. Traditional independent vacuum filtration or plate-and-frame filter pressing is difficult to achieve an ideal dehydration effect and has certain limitations. In order to solve the existing problems, the utility model providesthe fixed belt type vacuum extrusion filter which can simultaneously realize the vacuum negative pressure suction filtration effect and the filter pressing function of the plate-and-frame filter press and can continuously work. According to the fixed belt type vacuum extrusion filter disclosed by the utility model, a material passes through the vacuum water absorption belt on the left side on thefilter belt to realize primary dehydration of the material, and then the transmission wheel rotates to drive the filter belt to move so as to drive the material to enter the extrusion wheel, so thatsecondary dehydration is re
