Efficient solid-liquid thickener

Abstract

The invention discloses an efficient solid-liquid thicker, which comprises a container, a stirrer, a filtering medium and a slow flow piece, wherein the stirrer is stretched into the container, the filtering medium is arranged on the side wall in the container, a clearance exists between the side wall and the filtering medium, the bottom of the container is provided with a solid-liquid concentrate discharge outlet, the side wall of the container is also provided with a filtrate discharge outlet, the slow flow piece is arranged in the container and is used for slowing down the downward slowing speed of the solid-liquid mixture in the container, a plurality of flow disturbing pieces are uniformly distributed on the inner side wall of the container, the flow disturbing end of the flow disturbing piece is arc, the arc flow disturbing end is arranged between the filtering medium and the stirrer, the side wall of the container is also provided with a pulse valve which is connected with a high-pressure air source, and a gas outlet valve port faces the filtering medium. According to the efficient solid-liquid thicker, the problems that the existing sewage thicker device has low efficiency and cannot meet the requirement of continuous treatment of large amount of sewage are solved, and the efficient solid-liquid thicker has the advantages that the filtration and concentration efficiency is high, the requirement of continuous treatment of large amount of sewage can be met, the work is reliable and the use cost is low.

Description

Technical field [0001] The invention relates to a thickener mainly used for concentrating a solid-liquid mixture. Background technique [0002] According to the requirements of environmental protection, all kinds of industrial wastewater must be treated accordingly before being allowed to be discharged to the outside world. There are two common sewage treatment methods, one is to separate the harmful substances in the sewage from the water after various treatments, and the other is to concentrate the sewage to reduce the water content before proceeding to the next step. For the treatment of sewage containing a small amount of solid impurities, a coagulant is usually added to the sewage, and the various impurities are further solidified after thorough stirring, and then the solid matter is separated from the water by filtration. The Chinese invention patent application with publication number '102241467A' discloses a thickening device that can reduce the water content of mud. It ...
