Mixed reaction tank

Abstract

The invention discloses a mixed reaction tank which comprises a tank body and a stirring device, the lower parts of the front side of the tank body is provided with a water inlet pipe, the lower part of the tank body is provided with a medicament feeding pipe at the left side of the water inlet pipe, a 90 degree angle is between the water inlet pipe and the medicament feeding pipe, the right side surface of the upper part of the tank body is provided with a water outlet pipe, the inner wall of the tank body is provided with an overflow groove at the position of the water outlet pipe, and the bottom of the tank body is provided with a sludge discharge pipe. The mixed reaction tank adopts a motor to drive a three bladed propeller to stir so as to ensure full, uniform and quick mixing of a flocculant and sewage; and the overflow groove is arranged at the position of the water outlet pipe to prevent an unevenly-mixed fluid from flowing out; in addition, the bottom of the tank body is designed into a bucket shape to facilitate collection and discharge of sludge.

Description

technical field [0001] The invention relates to the field of water treatment equipment, in particular to a mixing reaction tank for sewage flocculation and sedimentation. Background technique [0002] In the process of sewage flocculation and sedimentation, it is necessary to put the flocculant into the mixing reaction tank and mix with the sewage to undergo a chemical reaction, so that the suspended particles in the sewage aggregate and become larger to form flocs, thereby accelerating the coagulation of particles and achieving solid-liquid separation. Purpose. At this time, the sewage treatment efficiency is not only related to the depth of the reaction tank, but also depends on the collision velocity of the flocculant and the particles. Most of the existing mixing reaction tanks are free flocculation mixing reaction tanks, which lack the stirring of the stirring device. , often cannot be fully mixed, resulting in insufficient flocculation, unable to meet the sewage discha...
