Submersible type mixing system based on water turbine

Abstract

The invention relates to a submersible type mixing system based on a water turbine. The submersible type mixing system based on the water turbine comprises a water turbine, a stirring impeller, a pedestal guide rail frame, a water suction pipe, a water pump and a water outlet flexible pipe, wherein the water suction pipe, the water pump and the water outlet flexible pipe is used for supplying water to the water turbine as a source of power and the water supply flow of the water pump is controlled by a regulating valve; the water turbine is installed on the pedestal guide frame and placed under the water; the stirring impeller is connected with a water turbine and is driven by a water turbine; the stirring impeller rotates to produce a thrust of water which pushes the flow of water. The working process of the submersible type mixing system is that the water pump pumps water from the pond to boost the pressure, the flow is controlled by the regulating valve, and enters a micro water turbine through a water inlet flexible pipe. The impeller is driven by the rotation of the water turbine, the installation position and direction of the hydraulic turbine can be controlled by the lifting and adjusting mechanism. The submersible type mixing system adopts a micro water turbine instead of a conventional submersible motor to drive the stirring impeller, thus submersible type mixing system can be adopted to various abominable working conditions, increase the continuous working time and service life of the stirrer are increased and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a water turbine-based submersible mixing system. Background technique [0002] In the sewage treatment process, especially when using MBBR packing or membrane technology and other treatment processes, due to the need for uniform mixing, submersible motor agitators are commonly used to generate push flow. The submersible motor agitator is mainly composed of a submersible motor, a stirring impeller and a mounting bracket. When working, the submersible motor drives the stirring impeller to rotate to generate water thrust, which promotes the uniform mixing of sewage. Sewage contains a variety of impurities, including microorganisms, sediment, solid particles, fibrous substances and various chemical substances. Therefore, submersible mixers need to operate continuously for a long time under harsh conditions, and reliability is very important. During the operation of the submersible mo...

AI Technical Summary

Problems solved by technology

During the operation of the submersible motor agitator, tiny solid particles in the sewage easily enter the gap between the sealing system and the shaft, and form a grinding effect during the rotation of the shaft, resulting in damage to the sealing system, sewage seeping into the motor cavity, and causing the motor to be short-circuited and burned

In order to prevent sewage from entering the motor cavity, on the one hand, it is necessary to enhance the sealing of the motor, which often affects the heat dissipation of the motor and shortens the service life of the motor; It will become shorter and shorter, greatly increasing maintenance costs, and frequent maintenance will also adversely affect the continuity of the water treatment process
