Dust removing device for open pit mine

Abstract

The invention discloses a dust removing device for open pit mine. The dust removing device sequentially comprises a mist spraying device, an air spraying device and a supporting seat from outside to inside; the mist spraying device comprises a water tank, a water pump, a water supplying pipe and a high-pressure water distribution main pipe, the high-pressure water distribution main pipe is of an annular structure, a plurality of high-pressure water distribution branch pipes are arranged on the inner side of the high-pressure water distribution main pipe in a communicating mode, and a pluralityof mist spraying heads are evenly arranged on the high-pressure water distribution branch pipes; the air spraying device comprises an air compressor, an air supplying pipe and a high-pressure air distribution main pipe, the high-pressure air distribution main pipe is of an annular structure, a plurality of high-pressure air distribution branch pipes are arranged on the inner side of the high-pressure air distribution main pipe in a communicating mode, and a plurality of air spraying heads are evenly arranged on the high-pressure air distribution branch pipes; and the inner ends of the high-pressure water distribution branch pipes and the inner ends of the high-pressure air distribution branch pipes are each of a closed structure. According to the dust removing device, a dust suppression mechanism arranged in the field for operation does not involve electrical components, and the safety in the using process is effectively ensured.

Description

technical field [0001] The invention belongs to the technical field of mining equipment, and in particular relates to a dust removal device for open-pit mines. Background technique [0002] In the mining process of open-pit mines, due to the use of various large-scale mobile machinery, dust and toxic gases have increased greatly. Through the dust detection on site, loading equipment, transportation equipment, and mining equipment are the main dust-producing equipment. [0003] Practice has proved that taking appropriate dust control measures according to the operating characteristics of each link can achieve good dust suppression effects. Usually, mining equipment will be equipped with corresponding dust suppression equipment to achieve instant dust suppression as mining progresses. However, for Due to the fluidity of the process, the dust generated by the installation and transportation equipment needs to be sprayed with water on a large area to suppress the dust on the job...

AI Technical Summary

Problems solved by technology

The dust suppression device adopted by this mechanism sprays through the high-pressure nozzle. Under the action of the fan, the coverage area of ​​the spray is increased. During long-term use, the fan works in a dusty and humid environment for a long time, and dust can easily enter the motor. or water, there are unsafe factors
