Automatic dosing device in feed water treatment process

Abstract

The invention discloses an automatic dosing device in a feed water treatment process, and relates to the technical field of water treatment. The device comprises a rectangular dosing box body and a speed reducer, the speed reducer is installed in the dosing box body through a supporting plate, and a partition plate is fixed to one opposite side wall of the dosing box body and a top surface; a first liquid gathering funnel is fixed between one side of the partition plate and the inner wall of the dosing box body; a water inlet pipe is fixedly arranged on the upper surface of the dosing box bodyand located just above the first liquid gathering funnel in a penetrating mode; a second liquid gathering funnel is fixed between the lower end of the partition plate and the inner wall of the dosingbox body; the side wall of the partition plate is rotationally connected with a first spindle through a bearing; and a water wheel is fixed to one end of the first spindle and located below the firstliquid gathering funnel. The designed dosing box body pushes a feeding disc assembly to rotate through water flow for dosing, mixing is conducted in a mixing box body, the mixing effect is good, automatic dosing is conducted with the entered water flow as power, and the problem that existing fixed dosing equipment is high in cost is solved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, in particular to an automatic dosing device in the water treatment process. Background technique [0002] At present, drugs such as coagulants and coagulants are required to be added to the water supply and sewage treatment of urban water purification plants and sewage plants. Make the water body meet the national drinking water or discharge water quality requirements. There are two existing dosing methods: dry dosing method and wet dosing method. At present, the wet dosing method is generally used, that is, the solid medicine is put into the medicine dilution device to mix the medicine and water, and then injected into the water body. At present, the mixing and stirring after drug administration is completed by driving the stirring shaft through the driving motor, which requires a large number of electronic devices for detection and subsequent mixing equipment, and the overall cost is r...
