A full negative pressure automatic slag discharge water release device for mining

Abstract

The invention relates to the technical field of automatic drains, and discloses a mine-used full negative pressure automatic slag discharge water release device, which includes a cylinder body, a water discharge valve is arranged at the bottom of one side of the cylinder body, and the upper end of the water discharge valve is fixedly connected There is a protective cover, the upper part of the other side of the cylinder is provided with a water inlet valve, the upper end of the cylinder is fixedly installed with an upper end cover, and both sides of the middle part of the upper end cover are provided with an air valve through the setting of the stirring device , the connecting rod can use the pulling force of the float. Since the collar is threadedly engaged with the bottom of the center guide rod, it can rotate when the collar rises and falls with the float, and drives the stirring blade to stir the water body at the bottom of the drainer to ensure the water body inside the drainer It is always in an active state, avoiding the sedimentation of waste residue at the bottom of the water release device, and can effectively mix the water body and waste residue and flow fully, so that the waste residue and wastewater can be discharged at the same time, and the waste residue can be discharged in a timely and effective manner to achieve the purpose of automatic slag discharge.

Description

technical field [0001] The invention relates to the technical field of automatic drains, in particular to a mine-used full negative pressure automatic slag discharge water drainer. Background technique [0002] In the mine gas drainage pipeline, the full negative pressure automatic slag discharge water release device is a water discharge device used under the negative pressure state of the pipeline, and the full negative pressure automatic slag discharge water discharge device is an indispensable automatic water discharge system for the coal mine gas drainage system The device is suitable for automatic drainage of main pipes, main pipes and branch pipes of the gas drainage and utilization system. The valve is opened, and the water discharge valve is closed under the negative pressure of the gas pipeline. At this time, the water in the gas pipeline can flow into the water discharge device through the water inlet pipe, and the float will rise with the rise of the water level. ...

AI Technical Summary

Problems solved by technology

[0003] However, there are still some defects in the actual use of the full negative pressure automatic slag discharge device: because the water discharge device is repeatedly watered and drained, and because the waste residue in the cylinder is in a relatively calm water body, almost every time it enters the water, After draining, there will be residues at the bottom of the cylinder, and the drainer needs to be cleaned after about a week of normal use; secondly, because the float is movably socketed on the upper part of the center guide rod, and the float slides relative to the center guide rod, once the center guide There is waste residue attached to the bottom of the rod, which will increase the friction of the float, make it difficult to move up and down, and even get stuck on the central guide rod, which seriously affects the normal operation of the water release device and brings great inconvenience to the enterprise.
