Gas-liquid mixing pump

Abstract

The invention provides a gas-liquid mixing pump. The gas-liquid mixing pump comprises a pressure gauge, an air intake duct, an automatic control mechanism, an air intake, a connecting pipe, an air chamber, a first pressure measuring port, a pressure meter, a second pressure measuring port, a pressure transducer, a liquid inlet, a liquid outlet, a stirring wheel, a bearing, a gearbox and a motor; the pressure gauge is arranged on the air intake duct and the air intake duct is connected to the automatic control mechanism; the air intake is arranged below the automatic control mechanism, and the automatic control mechanism is connected to the first pressure measuring port and the second pressure measuring port in order by the connecting pipe; the pressure meter is arranged above the first pressure measuring port with connection, and a connecting base is arranged below the first pressure measuring port with connection; the pressure transducer is arranged above the second pressure measuring port with connection, and a connecting base is arranged below the second pressure measuring port with connection; the motor is connected to the gearbox, the bearing and the stirring wheel in order; the liquid inlet and the liquid outlet are arranged at the left side of a pump case. The gas-liquid mixing pump has the beneficial effects that air input can be accurately controlled according requirements of different mixed liquors and self-adjustment of air pressure in the operation process is realized, the air pressure is constant, so that fully mixing of gas and liquid is realized and scrubbing effect is improved.

Description

technical field [0001] The invention relates to the field of gas-liquid mixing devices for air flotation machines, in particular to a gas-liquid mixing pump. Background technique [0002] In the decontamination process of the air flotation machine, the gas-liquid mixing process is particularly important and critical. The gas-liquid mixing pump is a commonly used gas-liquid mixing equipment for the air flotation machine, but most of the existing gas-liquid mixing equipment simply mixes gas and liquid. Through simple mechanical stirring movement, the gas is dissolved in the liquid, the dissolved amount cannot be guaranteed, and the efficiency is low. Contents of the invention [0003] The problem to be solved by the invention is: by precisely controlling the air pressure and the amount of the intake air, the gas-liquid can be fully mixed, and through precise feedback adjustment, the gas-liquid mixing can be kept in a stable state to ensure the dissolved amount and improve th...
