Sewage treatment device capable of quantitatively feeding treatment agent

Abstract

The utility model discloses a sewage treatment device capable of quantitatively putting a treating agent, and relates to the technical field of sewage treatment, the sewage treatment device comprises a protective shell and a stirring treatment cylinder, the inner wall of the protective shell is fixedly connected with a concentric-square-shaped guide frame, the inner wall of the concentric-square-shaped guide frame is slidably connected with a blocking flat plate, and the bottom of the blocking flat plate is fixedly connected with a metering cylinder; the outer circumferential face of the metering cylinder is fixedly connected with a special-shaped threaded block, the special-shaped threaded block is rotationally connected with a stress linkage plate through a positioning single rod, and one end of the stress linkage plate is fixedly connected with a throwing plate. Through the arrangement of the protective shell, the guide frame shaped like a Chinese character'hui ', a blocking flat plate, a metering cylinder, a special-shaped threaded block, a positioning single rod, a stress linkage plate, a throwing plate, a supporting frame, a limiting bottom plate, a one-way lead screw, a first direct current motor and a treating agent containing hopper, the effect of quantitatively throwing a treating agent can be effectively achieved, and the problem that the throwing amount of the treating agent is too large or too small is solved; and the structure is simple, and subsequent maintenance work is facilitated.
