Abstract

The invention relates to the technical field of environmental engineering equipment, in particular to a belt type filtering device. A belt type filtering device comprises a rack, a first roller shaft and a second roller shaft which are installed on the rack, and a filter belt with an annular structure which is installed on the first roller shaft and the second roller shaft. A suction device used for drying the filter belt on the upper layer and solids on the filter belt and an air injection device used for removing solids on the filter belt on the lower layer are arranged in the annular structure and connected with the rack. The suction device is used for drying the filter belt on the upper layer and solids on the filter belt, and the air injection device is used for blowing off the solids adhered to the filter belt on the lower layer, so that the belt type filtering device can be applied to solid-liquid separation of viscous solids which are difficult to dehydrate.

Description

technical field [0001] The invention relates to the technical field of environmental engineering equipment, and more specifically, to a belt filter device. Background technique [0002] In the existing industry, a belt filter is a common filter, which is similar to a belt conveyor, but the belt is replaced by a belt filter, which has the advantages of wide application range, continuous operation, and energy saving. However, the existing belt filters mainly rely on gravity to naturally drain water, and the solid-liquid separation efficiency is low for large specific surface areas, resulting in high water content in the obtained solids, thus limiting the application range of this technology in the chemical and environmental protection industries. Chinese patent application, publication number is: CN205832734U, discloses a kind of solid-liquid separation transmission device, and it comprises first roller and second roller, is provided with first conveyor belt and between descri...
