Background
At present, two blasting modes of the packaged emulsion explosive blasting and the bulk emulsion explosive blasting exist in China, the packaged emulsion explosive is high in cost, inconvenient and unsafe to produce, store and transport, and easy to pollute the environment during blasting, and the bulk emulsion explosive is safe, environment-friendly and low in cost and is strongly supported by national policies, but the usage ratio of the bulk emulsion explosive in China in the total usage amount of the explosive is not more than 30% every year, while the usage ratio of the bulk emulsion explosive in developed countries in Europe and America is more than 90%, so that the low usage ratio of the bulk emulsion explosive in China is mainly caused by the fact that the field mixing production process and the mechanized explosive loading equipment of the bulk emulsion explosive are lagged behind.
In addition, at present, more than 3 thousands of mining enterprises exist in China, most of mining modes of the mining enterprises mainly use open-air packaged emulsion explosive manual charging for blasting, dust and noise generated by the blasting modes cause serious environmental pollution, the efficiency is low, the labor intensity is high, the safety is high, the cost is high, the national policy has been issued to guide and support the mining enterprises to gradually change from open-air blasting to underground blasting, and simultaneously, with the vigorous investment of national infrastructure construction and highway, railway and tunnel construction, the market demands of mixed bulk emulsion explosives in underground, tunnel and roadway fields and blasting mechanical charging equipment become obvious day by day.
The prior art scheme has the following defects: at present, only a small number of blasting enterprises use a charging machine when carrying out underground, tunnel and roadway blasting, the existing charging machines all use a screw pump to convey an emulsion matrix, and simultaneously add a sensitizing agent into an emulsion matrix conveying pipeline through a peristaltic pump to be mixed and then convey the mixture into a blast hole to form bulk emulsion explosive for blasting, wherein, firstly, the proportioning of the emulsion matrix and the sensitizing agent controls the flow of the two pumps to carry out proportioning by controlling the rotating speed of the screw pump and the peristaltic pump, the peristaltic pump and the screw pump usually adopt an independent pumping system, and then the moving speed of the peristaltic pump and the screw pump is controlled by a control program of the control system to enable the peristaltic pump and the peristaltic pump to operate according to the speed set by the program, but in the actual operation process, the proportional movement of the matrix pump and the sensitizing agent pump is very difficult to realize, and the fluctuation of the system pressure often causes the inaccurate proportioning of the sensitizing agent and the emulsion matrix, secondly, no pumping system for adding catalyst is arranged in the prior art, so that the emulsion matrix sensitization effect is poor in sections and areas in cold weather due to too low sensitization temperature and incapability of adding catalyst, the mixed bulk emulsion explosive has poor performance and unsatisfactory explosion effect, or the emulsion matrix cannot be mixed due to too low temperature, and then, when a screw pump rotates to convey the emulsion matrix, the emulsion matrix is extruded out of a cavity by virtue of interference fit of a rotor and a stator, the rotor and the stator are in direct contact, the abrasion of the rotor and the stator is large, the rotor and the stator generally need to be replaced once a year, the maintenance cost is high, and the emulsion matrix is subjected to large shearing force when the emulsion matrix is extruded out of the cavity by the interference fit of the rotor and the stator, the emulsion matrix is seriously damaged, the temperature rise is fast, demulsification and crystallization are started after 3 times of repeated pumping generally, the explosive performance is seriously influenced, when an outlet is blocked or feeding is not smooth, a screw pump repeatedly rubs materials in a cavity, safety accidents are easily caused, when no materials exist, a rotor and a stator repeatedly rub, the temperature rise can reach more than 100 ℃ within 5 minutes, the safety risk is extremely high, 20 detonating accidents happen only in the civil explosion industry, and almost all the accidents happen every year.
