Walking type air floatation mixer

Abstract

The invention discloses a walking type air floatation mixer which comprises a walking platform; the upper surface of the walking platform is provided with a motor, a dosing pump, a fan and a dosing tank connected with the dosing pump; a walking roller wheel capable of moving in a guide rail is arranged at each of the two ends of the walking platform; the motor is connected with the walking roller wheels by transmission shafts; the bottom of the walking platform is provided with a support frame; a liquid distribution pipe connected with the dosing box and an aerator pipe connected with the fan are respectively fixed on the support frame; and an outlet end of the liquid distribution pipe is higher than that of the aerator pipe. The walking type air floatation mixer is simple in structure, low in energy consumption, even in dosing and rapid in mixed reaction; the walking type air floatation mixer gives priority to air agitation and is supplemented by mechanical agitation, and the solution in a tank can be completely mixed, so that the power is saved, and precipitate is prevented in an acidification pool; and the walking type air floatation mixer is simple to operate and can be automatically controlled in the whole process.

Description

technical field [0001] The invention relates to a device for preventing precipitation in an acidification tank, in particular to a walking air flotation mixer. Background technique [0002] At present, most acidification tanks do not have anti-sedimentation equipment. The acidic waste liquid (PH1-2) enters the acidification tank and undergoes neutralization reaction with the added alkali. The solution is pumped into the sewage treatment system through the sludge pump, and most of the sludge is deposited at the bottom of the tank, which is usually removed manually, which greatly increases the labor intensity of the workers and is accompanied by greater safety hazards. There are also some acidification tanks equipped with mechanical stirring devices. When adding alkali, turn on the stirring device to accelerate the reaction and prevent the reaction of precipitation. This device can better promote the mixing of the solution in the initial stage of operation, and has a certain e...

Problems solved by technology

[0002] At present, most acidification tanks do not have anti-sedimentation equipment. The acidic waste liquid (PH1-2) enters the acidification tank and undergoes neutralization reaction with the added alkali. The solution is pumped into the sewage treatment system through the sludge pump, and most of the sludge is deposited at the bottom of the tank, which is usually removed manually, which greatly increases the labor intensity of the workers and is accompanied by greater safety hazards

There are also some acidification tanks equipped with mechanical stirring devices. When adding alkali, turn on the stirring device to accelerate the reaction and prevent the reaction of precipitation. This device can better promote the mixing of the solution in the initial stage of operation, and has a certain effect on the control of the dosage. It has a positive impact and can fully discharge the sludge at the bottom of the pool, but the mechanical stirring device is immersed in acidic wastewater for a long time, seriously affecting its service life, insufficient safety and reliability, and high energy consumption
