Description

Inclined tube thickener Technical Field The utility model relates to a thickener, in particular to a diagonal tube thickener. Background The thickener (also called thickener) is a key device in the fields of mining, metallurgy, chemical industry and environmental protection, is mainly used for solid-liquid separation, and is used for concentrating solid particles in slurry by gravity sedimentation and discharging high-density underflow, and simultaneously recovering clarified liquid. The operation stability directly affects the production efficiency, the resource recovery rate and the operation cost. In the conventional inclined plate thickener, small particles are adsorbed on the surface of the inclined plate in the process of filling the material through the inclined plate, and the particles are accumulated more and more after long-time adsorption, so that the water passing area of the inclined plate is blocked, and the cleaning is very difficult. Therefore, the common method is to empty the sedimentation tank during overhauling or temporary shutdown, thoroughly wash and clean the sludge stored in the sloping plate by using high-pressure water, and eliminate the influence caused by the blockage of the sloping plate by the sludge. The cleaning in a short period affects normal operation, and has long working period and large workload. Disclosure of Invention The utility model aims to solve the technical problem of providing a chute thickener which has a compact structure and can effectively clean small particles on a sloping plate so as to ensure the integral solid-liquid separation efficiency.
