Description

Spraying dust-settling mechanism for coal conveyor Technical Field The utility model relates to the technical field of auxiliary dust fall of coal conveying equipment, in particular to a spray dust fall mechanism for a coal conveyor. Background In the process of mining, transporting and processing coal, a coal conveyor is one of the common devices, however, in the process of conveying coal, because the particles of the coal are small and dry, a large amount of dust is easy to generate, and the dust not only pollutes the working environment, but also can cause serious harm to the health of operators, and can cause safety accidents such as explosion and the like, so that the development of a spraying dust-settling mechanism for the coal conveyor is particularly important for improving the phenomenon. The dust settling device applied to the belt conveyor comprises a humidity sensor, a coal dust concentration sensor, a spraying device and a main controller, wherein the humidity sensor is used for detecting the humidity of coal, the coal dust concentration sensor is arranged at the transfer position of the belt conveyor and used for detecting the coal dust concentration, the main controller is respectively connected with the humidity sensor, the coal dust concentration sensor and the spraying device, when the humidity detected by the humidity sensor is lower than a preset humidity threshold value, and the coal dust concentration detected by the coal dust concentration sensor is higher than the preset concentration threshold value, the main controller controls the spraying device to spray at the transfer position, because a large amount of coal dust is not generated during transfer, dust removal operation can not be performed at this time, so that the problem of more water content caused by spraying excessive water mist can be avoided, in addition, the problem of more resources can be avoided, according to the above, the device can be applied better, but is generally not convenient to uniformly distribute in the area above the coal conveyor, the coal conveyor is not easy to be covered by the device, and the coal conveyor is not required to be improved, although the dust settling device has a certain limitation on the conveyor.
