Automatic arch breaking device for ammonium nitrate fuel oil explosive mixing and charging vehicle

Abstract

The invention provides an automatic arch breaking device for an ammonium nitrate fuel oil explosive mixing and charging vehicle. The device comprises a compressor driving the mixing and charging vehicle, a gas storage tank connected with the compressor, a stock bin used for storing ammonium nitrate fuel oil explosives. The automatic arch breaking device further comprises a gas pressure switch connected with the gas storage tank, a compression gas pipe connected with the gas pressure switch, a plurality of arch breaking gas discs installed on the inner wall of the stock bin, and a compressed air distribution unit eclectically connected with the gas pressure switch. The arch breaking gas discs are connected with the compression gas pipe. The problems that in a high-temperature and humid environment, porous granular ammonium nitrate is likely to cake and normal discharge can not be achieved are solved. Besides, the labor intensity of operators is reduced, safety hidden hazards are avoided, the quality of the ammonium nitrate fuel oil explosives is improved, waste high-pressure air of the mixing and charging vehicle is reasonably used, extra power consumption can not be generated, and energy conservation and environmental friendliness are achieved.

Description

technical field [0001] The invention relates to the field of ammonium oil explosives transportation, in particular to an automatic arch-breaking device for ammonium oil explosives mixed loading vehicles. Background technique [0002] On-site mixing truck is currently the most used explosive transport vehicle in the process of mine blasting. Among them, porous granular ammonium nitrate, one of the main raw materials of ammonium oil explosives, has the physical characteristics of easy moisture absorption and agglomeration. From the beginning of April to the end of October every year, the porous granular ammonium nitrate will agglomerate to varying degrees in the vehicle box and form an arched structure, resulting in difficulties in cutting materials and spiral idling at the bottom, especially in subtropical climate conditions. This phenomenon is particularly serious. Moreover, after the loading of the mixed truck is completed, long-term storage and long-distance transportati...

AI Technical Summary

Problems solved by technology

[0004]Although manual tamping can break the arched structure, when the agglomeration is serious, the operator needs to stand on the top to carry out the tamping operation. The labor intensity is high, and the vehicle When moving, it is necessary to go up and down the roof frequently, which not only delays production but also poses a safety hazard of falling from the roof
