Blasting impact fog-spray head protecting device

Abstract

The invention relates to a blasting impact spray head protection device, belonging to the technical field of mining machinery, comprising a Y-shaped spray head protection cavity (1), and the Y-shaped spray head protection cavity (1) includes a matching upper Y-shaped semicircular cavity (4) After being connected with the lower Y-shaped semicircular cavity (8), the upper Y-shaped semicircular cavity (4) and the lower Y-shaped semicircular cavity (8), one end is fixed by the connector (6), and the other end is fixed by the nut (2). A jet hole (10) is arranged in the middle of the cap (2), the lower Y-shaped semicircular cavity (8) is welded on the support fixed plate (7), and the bottom of the support fixed plate (7) is provided with an internally threaded installation pipe (9). The invention is simple in structure, easy to use, can increase the anti-collapse strength, reduce the damage rate of the high-pressure nozzle, reduce the operating cost, has good dust removal effect, can effectively reduce disposable dust, and avoids personal injury caused by toxic other to the staff, greatly improving the Work efficiency, with strong practicability.

Description

technical field [0001] The invention relates to a protection device for blasting impact spray heads, which belongs to the technical field of mining machinery. Background technique [0002] Blasting operations are required in the mining process, but a large amount of dust will be generated after blasting. In order to effectively prevent and control dust on the excavation face of blasting operations, the method of blasting high-pressure remote spraying is usually used for dust removal. The principle is blasting shock wave shock After the sensor in the main control box, the solenoid valve automatically opens to spray dust at the blasting point. The one-time dust source control effect is good and can effectively reduce the harmful and toxic gas content of the blasting smoke. However, due to the large destructive power of the blasting, the high-pressure nozzle is easily damaged by the blasting. It affects the dust removal effect, thereby reducing work efficiency, and the high-pre...
