Automatic high-pressure spray dust-settling device

Abstract

The invention discloses an automatic high-pressure spray dust-settling device which comprises a base plate. A water tank, a high-pressure spray pump and a motor are arranged on the base plate; the high-pressure spray pump is connected with a spraying device; and the water tank is connected with the high-pressure spray pump which is driven by the motor. A vacuum electromagnetic starter and a master control box are also arranged on the base plate; the vacuum electromagnetic starter is connected with the motor and the master control box, and an electronic control system is installed in the master control box. An electric ball valve I is arranged on a water inlet pipe, and an electric ball valve II is arranged on a water pipe which is used for connecting the high-pressure spray pump and the spraying device. A water level sensor is arranged in an inner cavity of the water tank, and a flow pressure sensor is arranged at a water discharge outlet of the high-pressure spray pump. A remote control signal receiver is arranged in the master control box which is further connected with an on-off sensor. The automatic high-pressure spray dust-settling device can be controlled remotely, can run automatically and can be in linkage operation with a coal mining machine; besides, spray efficiency of the automatic high-pressure spray dust-settling device is improved while water usage for spray can be saved.

Description

technical field [0001] The invention relates to coal mine dedusting technology, in particular to an automatic high-pressure spray dedusting device. Background technique [0002] Dust hazard is one of the six major disasters in coal mine production. Among the dust sources in coal mines, the dust produced by shearers and roadheaders accounts for the vast majority. The prevention and control of dust produced by coal shearers and roadheaders in all mines It is also the most important dust control project, such as coal mining machine dust source tracking, coal mining machine external spray, roadheader external spray, dust removal fan, roadheader foam dust removal, etc., are all dust removal equipment used for this. Among these dust removal equipment, the high-pressure external spraying of coal shearers and the high-pressure external spraying of roadheaders have the best dust reduction effect and are the most widely used. [0003] Most of the previously known methods of using the...

AI Technical Summary

Problems solved by technology

[0003] Most of the previously known methods of using the two dust suppression methods are to manually start the spray when the dust production equipment is running, and to manually close it when it stops, and the degree of automation is not high.

In addition, the dust suppression booster pumps used in the actual field are usually very large, and it is inconvenient to move in many occasions, and in most cases, there is no need for such a large amount of spraying water, which causes unnecessary waste

In addition, most of the existing spray pump stations for underground spraying and dust removal in coal mines on the market are independent working equipment, which do not have functions such as automatic control, remote monitoring, and intelligent linkage operation with mining machines, and the degree of intelligence is not high enough.
