Concrete conveying pump for mine sump

Abstract

The invention discloses a concrete conveying pump for a mine sump. The concrete conveying pump comprises a hopper, a motor and stirring mechanism, an S pipe valve and swing mechanism, an outer cover,a setting accelerator box, a hydraulic system, a conveying pump motor, an oil tank, a vacuum magnetic force starter, and a rack; the hopper is arranged on the right side of the rack, the motor and stirring mechanism is arranged in the hopper, the S pipe valve and swing mechanism is arranged on the left side of the hopper, the outer cover is wholly arranged on the top of the rack, the setting accelerator box is arranged on the top of the right side in the outer cover, the hydraulic system is arranged in the middle of the right side in the outer cover, the conveying pump motor is arranged on theleft side in the outer cover, the oil tank is arranged on the left side of the outer cover, and the vacuum magnetic force starter is arranged on the left side of the top of the rack. The conveying pump is simple in structure, reasonable in design, stable in work state, reliable in property, high in environment adaptation capacity and capable of achieving mechanical automation of mine sump clearing and excavating.

Description

technical field [0001] The invention relates to a concrete conveying pump for a coal mine water tank. Background technique [0002] The existing coal bunker dredging method has poor working conditions, high labor intensity, low efficiency, and high labor cost; the excavation cycle of the water bunker is long, and the single water bin runs for a long time, which threatens the drainage system; the clearing and excavation of the water bunker takes up vehicles, Reduce the turnover rate of vehicles, and the silt and water along the way will affect the safety of employees and the environment. [0003] In order to solve the current situation of dredging in the existing coal bunker, it was decided to adopt the combined dredging system of MQC mine car dredging trolley + HBMD mine concrete delivery pump. In the early stage of the application of this system, the combination of slurry pump and dredging trolley was used to clear the water tank. Because the slurry pump has high requireme...

AI Technical Summary

Problems solved by technology

In the early stage of application of this system, the combination of slurry pump and dredging trolley was used to clear the water tank. Because the slurry pump has high requirements on the viscosity of coal slime and the insufficient conveying capacity once affected the progress of clearing the water tank.
