Technical Field

The invention relates to the field of ammunition retirement treatment, in particular to a retired ammunition crushing system and method based on a hydraulic fracturing method.

Background

The existence of retired ammunition poses great threat to the life and property safety of people on one hand, and causes extra burden to storage, transportation, management and the like on the other hand, so that the safe and scientific treatment of the retired ammunition is very important. The ammunition processing method can be divided into a physical decomposition method, a chemical dissolution method and a biological degradation method, the explosive structural member is required to be physically separated before dissolution and degradation, and the explosive structural member is mechanically separated into a plurality of small explosives for subsequent processing by the technologies of water jet cutting, mechanical cutting, ultrasonic crushing and the like at present. However, mechanical cutting has a great safety risk to explosives, and the water jet cutting and ultrasonic crushing mode has high requirements on equipment and high cost.

Disclosure of Invention

The invention aims to make up the defects of high safety risk of mechanical cutting, high cost of a water jet cutting and ultrasonic crushing mode and the like, and provides a novel method which is based on a hydraulic fracturing method and can be applied to crushing of retired ammunition.

In order to achieve the technical effects, the invention adopts the following technical scheme:

the utility model provides a broken system of retired ammunition based on hydraulic fracturing method, this system includes computer, controller, servo hydraulic loading system and send and split the syringe needle, the computer is used for sending the pressurization instruction to the controller, the controller is used for issuing the instruction to servo hydraulic loading system, servo hydraulic loading system is used for exerting pressure to splitting the syringe needle, it acts on the retired ammunition to split the syringe needle to send.

The further technical scheme is that the number of the servo hydraulic loading systems is 1-5, the number of the fracturing needle heads is 1-5, and each servo hydraulic loading system corresponds to one fracturing needle head.

The invention also provides a decommissioned ammunition crushing method based on the hydraulic fracturing method, which comprises the following steps: firstly, drilling a plurality of holes on the explosive to be crushed, putting a fracturing needle head into the holes, sealing the holes, sending a pressurizing instruction to a controller through a computer, enabling a servo hydraulic loading system to apply pressure to the fracturing needle head until the holes are fractured, continuing pressurizing to rapidly expand cracks until the pressure cannot be maintained, and sequentially fracturing the holes by adopting the same method to achieve the purpose of crushing the explosive.

The method has the further technical scheme that the method can also place a plurality of fracturing needle heads into a plurality of drill holes simultaneously, and the computer sends a pressurizing instruction to the controller at the same time, so that a plurality of servo hydraulic loading systems apply pressure to the fracturing needle heads simultaneously, and a plurality of holes can be fractured simultaneously.

The further technical scheme is that the diameter of the hole is larger than that of the fracturing needle head.

Compared with the prior art, the invention has the following beneficial effects: the system is simple, convenient to operate and low in cost, the crushing process belongs to a quasi-static process, and the safety risk is low. The degree of crushing can be controlled by controlling the drill hole spacing. Meanwhile, the crushing efficiency can be greatly improved by adopting an array pressurization fracturing mode.
