Automatic control system for producing emulsion ammonium nitrate-fuel oil explosive

Abstract

The invention relates to an automatic control system for producing an emulsion ammonium nitrate-fuel oil explosive. The automatic control system for producing the emulsion ammonium nitrate-fuel oil explosive is characterized in that the automatic production line comprises an explosive preparation assembly, a packaging assembly, a stacking assembly and a loading assembly which are sequentially arranged along the production order of the emulsion ammonium nitrate-fuel oil explosive, and the automatic control system includes a porous granular ammonium nitrate unpackaging control module, a materiallevel detection control module, a motor control module, a package spacing control module and an online explosive quantity control module. The system realizes continuous automatic and safe production,reduces the labor intensity, achieves the unmanned purpose, specifically realizes continuous automatic metering and feeding of raw materials, continuous automatic mixing, continuous automatic packingand large package automatic stacking and loading, achieves intelligent linkage across the entire line, and is provided with safety interlock protection; and the control of the spacing between the explosive packages effectively realizes the anti-sympathetic detonation function, reduces the possibility of explosion in the production process, and further improves the safety of the production line.

Description

technical field [0001] The invention belongs to the field of production of emulsified ammonium oil explosives, in particular to an automatic control system for the production of emulsified ammonium oil explosives. Background technique [0002] Emulsified granular ammonium oil explosive (also known as heavy ammonium oil explosive) is an industrial explosive mixed with emulsion explosive matrix and porous granular ammonium oil explosive, that is: porous granular ammonium nitrate and light diesel oil are mixed in proportion to form a porous granular Ammonium oil explosives, porous granular ammonium oil explosives and different ratios of latex matrix form emulsified granular ammonium oil explosives with different properties. The explosive has the advantages of intrinsic safety, high density, high detonation energy, and low cost, and has certain water resistance; the explosive can flexibly adjust the ratio according to engineering requirements, and combines the technologies of la...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the domestic ground fixed production line is not highly automated. The latex matrix needs to be pre-prepared in the storage tank and then mixed with porous ammonium nitrate. Continuous mixing with the emulsified matrix and automatic packaging and loading after mixing cannot be realized. And the labor intensity is high, there are still too many online personnel, and the whole line needs 9 people

[0005] In short, there are existing fixed production lines for emulsified granular ammonium oil explosives in China, and the degree of automation of the process technology is not high. Ammonium oil mixing still needs to be mixed with ammonium oil trucks and then poured into the mixing tank in the workshop. Workers use small carts to add latex to the mixing tank. Internal mixing, backward technology, low safety, unautomated drug filling, packaging and loading, resulting in too many online operators, unable to adapt to the national industrial policy requirements of less (no) humanized production lines
