Abstract
Description
Technical Field
[0001] This utility model belongs to the field of solid rocket engine propellant technology, and in particular relates to a tool for cleaning propellant slurry. Background Technology
[0002] Currently, cleaning the propellant slurry during rocket loading is a highly dangerous operation. Since the components of the slurry are mostly flammable and explosive hazardous chemicals with extremely high energy, they can burn and explode under external stimuli such as heating, friction, compression, and static electricity. Once an explosion occurs, it can cause casualties and huge property damage.
[0003] Meanwhile, the slurry has a certain degree of toxicity, as does the ethyl acetate used in cleaning it. If absorbed by the human body, it can cause damage.
[0004] Currently, bamboo strips are used to clean the slurry during the casting process. Bamboo strips are widely used because they are anti-static and do not easily generate sparks. Cleaning the discharge sleeve during the casting process is relatively difficult, especially due to its length and sometimes narrow diameter. The structure of the discharge sleeve and the distribution pipe is as follows: Figure 1 As shown.
[0005] Because the bamboo strips are narrow, multiple passes along the circumference are required to remove the slurry during cleaning. For longer sleeves, the sleeve must be flipped over to clean from the other side. The bamboo strips are also hard and do not fit well into the straight pipe channel, leaving a significant amount of slurry residue after cleaning. Using solvents increases the amount of solvent needed. The cleaning process is time-consuming and ineffective, resulting in both poor cleaning results and low efficiency. Utility Model Content
[0006] The technical problem solved by this utility model is to overcome the shortcomings of the prior art and provide a tool for cleaning slurry, which can improve cleaning efficiency and cleaning effect.
