Automatically controllable explosive slurry casting system

Abstract

The invention discloses an automatically controllable explosive slurry casting system. A castable tank is communicated with a casting tank through a charging valve; a suspension valve is arranged in the castable tank and has a cone-like structure; the outer diameter of the suspension valve is matched with the inner diameter of the castable tank; and the lower structure of the suspension valve is matched with a charging hole of the castable tank. The suspension valve is used for controlling the liquid level of the explosive slurry in the casting process and cutting off the slurry charging whenthe casting is completed. Meanwhile, in order to facilitate controlling, detaching and cleaning the suspension valve, the slurry castable tank is modularly designed. The slurry in the castable tank can be automatically cleaned in real time, the system can be automatically closed when the slurry casting is completed, and safety accidents due to leakage of a vacuum system cannot be caused; meanwhile, the operation of personnel on dangerous goods is reduced.

Description

technical field [0001] The invention relates to an automatically controllable propellant slurry pouring system, which belongs to the technical field of propellant production equipment and is mainly used for pouring propellant slurry to reduce or avoid excessive exposure of operators to dangerous environments. Background technique [0002] The manufacture of thermosetting explosives (such as composite solid propellants, plastic bonded explosives (PBX), etc.) generally consists of mixing, slurry pouring, curing and other processes. Slurry pouring is to remove the gas wrapped in the explosives slurry to obtain dense explosives products. The specific operation is to put the uniformly mixed and flowable propellant slurry into a constant temperature pouring material tank, let it drip into the mold or product shell to be formed at a certain speed, and maintain a vacuum state during the drip irrigation of the slurry , to remove the gas in the slurry. See attached figure 1 . Due ...

AI Technical Summary

Problems solved by technology

However, on the one hand, this system is expensive and requires large capital investment, so it is not suitable for small pouring systems; on the other hand, it cannot clean the medicine slurry in the material tank in real time, and there is a lot of medicine slurry in the material tank, and when there is little medicine slurry residue Can cause safety accidents due to air leakage in the vacuum system
