Coagulant feeding apparatus of water purifying device

Abstract

The invention discloses a coagulant feeding apparatus of a water purifying device. The coagulant feeding apparatus comprises a settling pond, wherein the top of the settling pond is fixedly connectedwith first tracks which are disposed on two sides of a first straight rack, the top of the settling pond is fixedly connected with second tracks which are disposed on two sides of a second straight rack, the top of each first track is connected with a first driving apparatus in a sliding manner, the top of each second track is connected with a second driving apparatus in a sliding manner, a movingplate is arranged between the first driving apparatus and the second driving apparatus in a threading manner by virtue of a lead screw, the top of the moving plate is fixedly connected with a feedingpump, a water inlet end of the feeding pump is communicated with a water inlet pipe, a water outlet end of the feeding pump is communicated with a water outlet pipe, one end, away from the feeding pump, of the water outlet pipe is communicated with a first three-way connector, and two ends of the first three-way connector are communicated with a feeding pipe. The invention relates to the technical field of water purification. By adopting the coagulant feeding apparatus of the water purifying device, the problem that the addition amount of the coagulant is difficult to control due to differentturbidity in the settling pond can be solved, and the water purifying efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a coagulant dosing device for water purification equipment. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water and is an equipment for purifying water quality. Using the natural precipitation or coagulation and sedimentation of water to remove suspended solids in water, sedimentation tanks are widely used in water treatment. Since the coagulant is put into water, most of them can provide a large amount of positive ions, and the positive ions can neutralize the negative charge on the surface of the colloidal particles, so that the repulsion between the particles is reduced, so that they are easy to approach and condense into flocculent fine particles. The process of destabilizing the fine colloidal particles in water and agglomerating them into tiny fine particles is realized. Tiny fine particles...
