Novel belt type vibratory rolling filtering device

Abstract

The invention provides a novel belt type vibratory rolling filtering device. The novel belt type vibratory rolling filtering device comprises belt type vibratory rolling filtering machines which are oppositely arranged, wherein each filtering machine comprises a rack; the rack comprises an upper supporting frame and a lower supporting frame; a layering distribution device is arranged at the upstream end of the upper supporting frame; in the material flowing direction, the rack is provided with a guiding roll, a vibrating part, a driving rolling part and a tensioning roll in sequence; a ring-shaped filtering belt is arranged around the guiding roll, the vibrating part, the driving rolling part and the tensioning roll; the left driving rolling part comprises a first extruding and dewateringroller positioned on the upper supporting frame and a second driving electric roller positioned on the lower supporting frame; the right driving rolling part comprises a second extruding and dewatering roller positioned on the lower supporting frame and a first driving electric roller positioned on the upper supporting frame; extruding gaps are respectively formed between the first extruding and dewatering roller and the first driving electric roller, between the two filtering belts surrounding the left driving rolling part and the right driving rolling part and between the second extruding and dewatering roller and the second driving electric roller. The novel belt type vibratory rolling filtering device provided by the invention has the advantages that the liquid content of filter cakesis low and the productivity is improved.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation and filtration, and in particular relates to a novel belt-type vibration roller pressure filtration device. Background technique [0002] Solid-liquid separation is an important process link in mining, metallurgy, chemical industry, papermaking, food, environmental protection and other industries. High-efficiency and energy-saving solid-liquid separation equipment is the key to ensure the stable and reliable operation of the process. The main equipment for solid-liquid separation of fine-grained mud is the filter, but the existing various filters generally have disadvantages such as low efficiency, high energy consumption, large liquid content in the filter cake, and cloudy filtrate. [0003] At present, the existing filters mainly include vacuum filters, pressure filters, centrifugal filters and belt filters. Among them, the vacuum filter relies on vacuum negative pressure dehyd...
