Water washing flotation machine capable of efficiently discharging and separating sludge and working method thereof

Abstract

The invention discloses a water washing flotation machine capable of efficiently discharging and separating sludge and a working method thereof. The water washing flotation machine comprises a heavy material conveyor immersed in water and a light material collector floating in the water surface, wherein a feeding cylinder partially immersed in water is arranged above the heavy material conveyor, alifting material pressing plate is arranged above the feeding cylinder, an aeration mechanism is arranged below the heavy material conveyor below the feeding cylinder, gas generated by the aeration mechanism penetrates through the heavy material conveyor and can drive a light material to move upwards, the output end of the heavy material conveyor is connected with a vibrating screen, a material collecting box is arranged below the vibrating screen, and the material collecting box is connected to the feeding cylinder through a conveying mechanism. A flap valve at the bottom of a box body of the water washing flotation machine adopts an electric air valve for replacing manual operation, so that man-hours are greatly reduced; a sludge discharging spiral reamer adopts chain wheel transmissionfor replacing triangular belt transmission, so that the probability of faults of the system is reduced; and the screening equipment effectively separates small construction waste regeneration particles from the sludge, so that the discharged sludge is classified and utilized.

Description

technical field [0001] The invention relates to the technical field of water-washing flotation machines, and provides a water-washing flotation machine with high-efficiency sewage discharge and discharge classification and a working method thereof. Background technique [0002] Washing flotation machine is one of the main equipment to remove light impurities such as wood, rubber, packaging waste, waste paper, cloth and plastic in construction waste. The construction waste containing light matter enters the water from the feed port of the washing flotation machine, and the light matter and pure construction waste are separated according to the difference in density between the mixed material and water. Heavy material (pure construction waste) settles to the receiving section of the belt conveyor under water and moves to the dewatering screen along with the belt, and enters the material receiving point of the next process after dehydration; light material floats to the scrapin...

AI Technical Summary

Problems solved by technology

In the actual working process, once more particles enter the gap of the mud discharge reamer, when the rotation of the reamer is greatly hindered, the V-belt cannot transmit large power to eliminate the resistance, and the reamer stops working as a result. When the problem is serious even burn the motor

[0006] The sludge discharged from the bottom of the water washing flotation machine contains more small particles of recycled aggregate. After dehydration, this sludge can only be used as green planting soil, and the use effect is poor.
