Abstract

The invention discloses a high-efficiency solid-liquid thickener which comprises a container, a stirrer, a filtering medium and a slow flow piece, wherein the stirrer comprises a stirring shaft and a stirring paddle arranged on the stirring shaft; the stirrer stretches into the container; the filtering medium is arranged on a side wall of the container; a certain gap is formed between the filtering medium and the side wall of the container; the bottom of the container is provided with a solid-liquid concentrate discharge port; a filtrate discharge port is formed in a side wall of the container; the slow flow piece is arranged in the container and is used for reducing the flowing speed of the solid-liquid mixture in the container; a plurality of turbulent flow pieces are uniformly distributed on the inner wall of the container; turbulent flow ends of the turbulent flow pieces are arc; and the arc-shaped turbulent flow ends are positioned between the filtering medium and the stirrer. The problems that the conventional sewage concentration device is low in efficiency and the requirement of continuous treatment of a great quantity of sewage cannot be met are solved, and the high-efficiency solid-liquid thickener has the advantages of meeting the requirement of continuous treatment of a great quantity of sewage, and having high filtering concentration efficiency, reliability in operation and low using cost.

Description

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