The device includes a rack 1, a reducer I2, an end cover 3, a rotating stand 4, a rotary joint 5, a mixer 6, a sealing cover 7, a shaft bed 8, an air cylinder 9, a guidepost 10, a rotating arm 11, a reducer II12, a bearing I13, a seal ring 14, a groove plate 15, a bearing II16, a gear I17, a gear II18, a motor 19, a rotary shaft I20, a rotary shaft II21, a temperature sensor 22, a sealing cap 23, a filter cap 24, a bearing III 25 and a pipeline 26. The mixer 6 is connected with the reducer I2 and the reducer II12 through the rotating stand 4 so as to achieve adjustment of the inclination angle of the mixer 6 and adaptation to mixing of materials of different in-process quantities; the mixer 6 has the functions of real-time temperature measurement and dust filtering, and no manual operation is needed at the mixing site so as to achieve safe operation; and through the device, the function of mixing of solid-liquid explosive materials can be achieved, and the safety and efficiency of material mixing can be improved.

Description

technical field [0001] The application belongs to the field of propellant and explosive material mixing, and relates to a device capable of safely mixing different solid-liquid propellant and explosive materials in preparation, which improves the safety and efficiency of material mixing. Background technique [0002] In the molding process of propellant and explosive products, the materials of the formula should be mixed first, and the given mixing uniformity and flow state should be achieved, so as to facilitate the subsequent charge molding. Due to the extremely high risk of propellant and explosive materials, there are strict requirements on the quantity of materials in the mixing process, so low-quality mixing methods seriously affect the safety and efficiency of operations.

AI Technical Summary

Problems solved by technology

Due to the high risk of propellant and explosive materials, there are strict requirements on the quantity of materials in the mixing process, so the low-quality mixing method seriously affects the safety and efficiency of the operation.

[0003] In the current situation where the explosives formula materials are mixed with operators operating equipment on site, the mixed production volume is single, the operation efficiency is low, and the risk is high, and there are potential safety hazards for the operators.

By searching the existing material mixing equipment and analyzing its operation process, there are the following problems: 1. In traditional material mixing equipment, the mixer is designed according to a fixed volume, and the mixer is fixed, resulting in an adjustable volume of material mixing The range is single; 2. The existing material mixing equipment contains paddles, and there is extrusion between the paddles and the wall surface of the material, and personnel are required to open and close the valve and end cover on site, which has potential safety hazards in the mixing process; 3. In addition, traditional materials The inner wall of the mixer of the mixing equipment has no groove plate, which weakens the fluidity of the material in the cavity and affects the mixing efficiency
