Waste emulsion explosive treatment method and device

Abstract

The invention discloses a waste emulsion explosive treatment method and device, belongs to the technical field of civil explosive chemical production, and solves the problems of miss-fire explosion and the like of waste emulsion explosive treatment products in the prior art. The waste emulsion explosive treatment method comprises the following steps that waste explosive is added into a discharging hopper; the waste explosive is sieved by a sieve; waste explosive enters the material distributing and conveying screw device and is conveyed to the discharge port through a material distributing and conveying screw; waste explosive enters the conveying device from the discharge hole; the conveying device is used for heating the waste explosive; and the heated waste explosive enters a sensitizing machine through a conveying device, enters an automatic explosive charging machine and is finally subjected to plastic film packaging. The waste emulsion explosive treatment device comprises a discharging hopper, a screen, a distributing and conveying screw device, a distributing and conveying screw, a discharging port and a conveying device, the screen is arranged at the lower end of the discharging hopper, the discharging hopper is arranged at the input end of the distributing and conveying screw device, the discharging port is formed in the output end of the distributing and conveying screw device, and the conveying device is provided with a heating device.

Description

technical field [0001] The invention belongs to the field of emulsion explosive production in the civil explosive industry, and relates to a treatment method and device for emulsion explosive waste. Background technique [0002] At present, the automation degree of the emulsion explosive production line in the civil explosive industry is getting higher and higher, and the speed of the emulsion explosive charging machine in the production process is also very fast, but the higher the degree of automation, the higher the requirements for equipment and raw materials. Emulsion explosives are packaged in plastic film, glued together by plastic film, and fixed at both ends by buckles to form a sausage-style packaged product. During the production process of emulsion explosives, for example, when the equipment is turned on, the residues in the equipment and pipelines, that is, the head and tail of the material, etc., and the plastic film is not completely glued, the buckle is not t...

AI Technical Summary

Problems solved by technology

According to industry standards, waste emulsion explosives need to be processed separately in the rework workshop. However, in order to save time and manpower in the actual production process, enterprises often carry out waste treatment in the sensitization process of the existing emulsion explosive production line, which is different from the production process. The production of mixed products is not conducive to the safe production of the civil explosive industry

[0003] First, when the equipment is turned on, the materials such as the head and tail of the equipment and pipelines are processed in the normal production line, and the product temperature has dropped to the ambient temperature, which is quite different from the sensitization temperature of the normal emulsification matrix by 50-60 degrees. Add the normal product When the overall temperature is lowered, it directly affects the performance of the product, resulting in the failure of the product to explode when used in blasting engineering, which directly affects the safety of blasting engineering.

[0004] Second, when there are problems such as incomplete gluing of the plastic film and loose clamping of the buckles, due to the high production efficiency of the charge machine equipment, the amount of waste emulsion explosives that appear is large, and the operators of the production line will pile up the waste medicines. Or the equipment removes the plastic film or buckle, then puts the waste medicine into the waste medicine collection barrel, and then puts it into the production line medicine filling machine to mix with the normal product for medicine filling. The product is not treated separately. During the waste medicine treatment process, due to waste The medicine contains impurities such as plastic film, metal buckles, etc., and enters the normal production equipment, causing friction to cause local overheating and explosion accidents. The amount of medicine on the production line is large, and serious safety accidents occur. It may lead to the failure of blasting when the product is used in blasting engineering, which directly affects the safety of blasting engineering
