Description

Novel mine bottomless valve drainage device

Technical Field

The utility model belongs to the technical field of mining equipment, concretely relates to novel mining bottomless valve drainage device.

Background

The centrifugal water pump is mainly composed of impeller, pump shaft, pump shell and bearing, before starting, the water pump is filled with water, then the motor is started, the water is driven by the motor to rotate to produce centrifugal force, the water in the impeller flows from inlet to outlet of the water pump under the action of centrifugal force, and is discharged from spiral diffusion chamber into drainage pipeline, at the same time the pressure of inlet of the impeller is reduced due to discharge of water to form partial vacuum, the water in underground water storage tank is pressed into inlet of the impeller through suction pipe under the action of atmospheric pressure, so that the rotating impeller can continuously suck and discharge water, and before starting the water pump, the conventional drainage system requires that the water pump body and water inlet pipe are in vacuum state, and the bottom valve mounted at lower end of suction pipe is equivalent to a one-way valve, when the water pump is filled with water and stopped running, the bottom valve is closed to make the water pump body and water inlet pipeline full of water and not leak, when the water pump is operated, the water in the pump is discharged to form vacuum, so that the water in the underground reservoir jacks the valve core of the bottom valve under the action of atmospheric pressure, and is pressed into the impeller through the water suction pipe. Thereby allowing water to be continuously sucked and discharged.

The existing bottom valve has the following problems in use:

1. the damage often can appear because mineral substance and coal slime grit in the mine in the water pump bottom valve in the operation, perhaps causes the sealed damage of bottom valve because operating personnel's misoperation, leads to can't filling the diversion and can't start.

2. The existing water pump bottom valve is large in size and heavy, the underground condition is poor, the environment is severe, the labor intensity of overhauling and replacing the bottom valve is high, and the normal drainage of the water pump is easily influenced.
