Raw material preparation device for sewage treatment

Abstract

The invention discloses a raw material preparation device for sewage treatment. The device comprises a shell, the shell is a hollow cylindrical structure, the top end of the shell is connected with afirst rotating motor, the output shaft of the first rotating motor faces downwards, goes through the top end of the shell, extends to the internal of the shell and is connected with a rotating plate,the bottom end of the rotating plate is rotatably connected with the inner wall of the bottom end of the shell, the sidewalls of two sides of the rotating plate are connected with two symmetrically arranged cylindrical shells along the length direction, the cylindrical shells are hollow structures, and an opening is arranged in one end, away from the rotating plate, of every cylindrical shell. Thedevice has a novel structure, can quantitatively store the preparation material of the raw material for sewage treatment, avoids material wastes, allows the preparation material to be fully stirred in the shell in order to achieve uniform mixing, and allows the raw material adhered to the inner wall of the shell to be timely cleaned during stirring in order to avoid the influences of the adherence of the material to the inner wall of the shell on later use.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to raw material preparation equipment for sewage treatment. Background technique [0002] The most commonly used sewage treatment chemicals are flocculants, which are divided into two categories: inorganic flocculants and organic flocculants. The flocculation and precipitation method is to select an inorganic flocculant (such as aluminum sulfate) and an organic anionic flocculant polyacrylamide (PAM) to prepare an aqueous solution and add it to the wastewater, which will produce a compressed double layer, making the suspended particles in the wastewater lose stability. Colloidal particles coagulate with each other to increase the size of particles, forming flocs and alum flowers. After the floc grows to a certain volume, it will separate from the water phase and settle under the action of gravity, thereby removing a large amount of suspended solids in the wastewater, there...

AI Technical Summary

Problems solved by technology

[0003] In the preparation of sewage raw materials, ordinary preparation equipment does not stir sufficiently when preparing raw materials, and cannot control the ratio of raw materials well, so it will lead to waste of part of the preparation materials, causing them to adhere to the side wall of the preparation, and the long-term Therefore, in order to solve such problems, we propose a raw material preparation equipment for sewage treatment
