Problems solved by technology

The traditional method of cutting with knives requires manual close-range operations. Not only the propellant medicine is harmful to the body, but also the propellant can easily cause accidents such as combustion and explosion after being subjected to mechanical action; or use high-pressure water jets for cutting, although it reduces The cutting temperature is lowered, but the cutting efficiency of this technology is extremely low, which can easily lead to aerosol accumulation and increase the probability of secondary disasters
[0003] Existing solid rockets and missile motors are postponed for replacement and propellant cleaning has the following problems: 1. Most of the solid propellant cleaning process is boring and turning powder columns. The production efficiency is very low, and there are certain safety risks in the cleaning process; 2. Large-scale engine solid propellant adopts high-pressure water cutting to generate a large amount of industrial wastewater. The cutting wastewater contains a large amount of oxidant ammonium perchlorate and other harmful components, which is difficult to be harmless 3. Due to the participation of desensitizers and high-pressure water, the propellant formula undergoes physical and chemical changes during the cleaning process, resulting in the basic failure of the cleaned propellant, resulting in a waste of energetic material resources

Embodiment 1

[0025] In order to overcome the problems of low production efficiency, potential safety hazards in the existing cutting tool cleaning operation, and large pollution of water jet cutting cleaning chemicals, the present invention provides such figure 1 A solid rocket motor physical medicine cleaning device is shown. The invention cuts the propellant to form an annular groove array through the revolution of the engine + the rotation of the cutter, and cuts the propellant to form strips of medicine by cutting the propellant through the revolution of the engine and the linear motion of the cutter; the whole cleaning The medicine process realizes the low-speed and high-efficiency cleaning of the propellant, and the invention uses a physical tool to clean the medicine. Compared with the high-pressure water cutting method, it is green and environmentally friendly, and the cut propellant can be reused to avoid environmental protection problems caused by destruction.

Abstract

The invention belongs to the technical field of solid rocket engine reloading and explosive cleaning, and particularly relates to a physical explosive cleaning device and method for a solid rocket engine. The physical explosive cleaning device for the solid rocket engine comprises an equipment base and an obliquely-arranged working platform, parallel sliding rails are arranged on the working platform, and a cutter feeding mechanism, a first rocket engine slide base and a second rocket engine slide base are sequentially arranged on the parallel sliding rails; a cutter conversion disc is arranged on the cutter feeding mechanism, and an annular cutter and a scraper knife are fixedly connected to the cutter conversion disc; and an anti-explosion servo motor, a second transmission gear and a second rocket engine fixing chuck are arranged on the second rocket engine slide base, and a first transmission gear and a first rocket engine fixing chuck are arranged on the first rocket engine slide base. By adopting a low-temperature annular cutting mode, the explosive cleaning efficiency and the safety of the explosive cleaning process are improved, the environmental pollution is reduced, and meanwhile, a cut retired propellant material is safely cleaned and recycled.

Description

technical field [0001] The invention belongs to the technical field of solid rocket motor repacking and clearing medicine, and in particular relates to a physical medicine clearing device and a medicine clearing method of a solid rocket motor. Background technique [0002] The "disposal" of existing solid rockets and missile engines is a task with great difficulty, high technical content and low safety factor. How to effectively remove the solid propellant in the engine, while ensuring a certain safety factor, and realize the effective recycling of the engine casing is one of the difficult problems to be solved by scientific research and technical personnel. The traditional method of cutting with knives requires manual close-range operations. Not only the propellant medicine is harmful to the body, but also the propellant can easily cause accidents such as combustion and explosion after being subjected to mechanical action; or use high-pressure water jets for cutting, althou...
