Circular agitating and dispensing device for double-port hand pump

Abstract

The invention discloses a circular agitating and dispensing device for a double-port hand pump and belongs to the dispensing field of sewage treatment. The circular agitating and dispensing device comprises a dispensing tank, a liquid level sensor, an upper suction pipe, a lower suction pipe, a plastic pump suction pipe, a solenoid valve, a plastic pump, a measuring pump, a liquid medicine storage tank and an agitating spray nozzle and is characterized in that a pipe orifice of the upper suction pipe and a pipe orifice of the lower suction pipe are positioned in a circle center of the dispensing tank; the upper suction pipe and the lower suction pipe are connected with the plastic pump suction pipe; the plastic pump suction pipe is connected with a plastic pump inlet; the plastic pump is connected with an agitating pipe; and the agitating pipe is connected with the agitating spray nozzle. The dispensing tank is characterized in that the bottom of the dispensing tank is connected with a liquid medicine conveying pipe, and the agitating spray nozzle is installed at the lower side part of the dispensing tank; and the upper suction pipe is characterized in that the pipe orifice is positioned at 1 / 2-1 / 3 of the total height of the dispensing tank and in the center of the dispensing tank, and the upper suction pipe is horizontal. The liquid medicine storage tank is installed below the dispensing tank, and the upper part of the liquid medicine storage tank is connected with the liquid medicine conveying pipe; and the end of the pipe orifice of the lower suction pipe inclines downwards. The circular agitating and dispensing device has the characteristics of low equipment investment, simple structure, uneasiness in blockage, pump overload prevention and easiness in maintenance and replacement.

Description

technical field [0001] The double-port parallel pump circulation stirring dispensing device of the present invention relates to a pump circulation stirring medicine dispensing device. Background technique [0002] The mixing and dispensing method of the agitator driven by the variable speed of the motor that is generally sold on the market and is being used in general sewage stations. [0003] The mixing form is mainly composed of a stirring motor, a high transmission ratio reducer, a mixing blade, a dispensing tank, a support stand, etc. The high transmission ratio reducer generally adopts a cycloidal pinwheel reducer, which has a complex structure and high manufacturing precision requirements , high cost, difficult maintenance, and high technical requirements for maintenance workers. Generally, when this kind of reducer fails, it will be replaced with a new one, resulting in high maintenance and repair costs. [0004] For a long time, the rated power of the various sizes ...
