preparation example Construction

[0015] To achieve the above object, the preparation method of the present invention comprises the following steps:

[0016] Step 1: Take No. 30 engine oil (or 50°C kinematic viscosity at 25mm 2 / s~35mm 2 Oil products with high ignition point between / s) are soaked to form an oil film on the surface of waste products and sensitive chemicals exposed to them, and use the viscosity of the oil and the characteristics of being difficult to ignite at room temperature to effectively passivate the friction of such products. , electrostatic and impact sensitivity purposes;

[0017] The working principle is: suitable viscosity (kinematic viscosity at 50°C is 25mm 2 / s~35mm 2 / s) oil products use their flow rate to avoid the danger of combustion and explosion caused by friction, impact and static electricity between products caused by too fast flow rate; suitable viscosity (kinematic viscosity at 50°C is 25mm 2 / s~35mm 2 / s) oil makes use of its viscosity to make the oil form an isol...

Embodiment

[0021] Waste handling process:

[0022] Put the product into the special container → put the specified number of containers into the special manual transport device → load it into the special transportation tool → reach the passivation treatment room → put it into the special immersion device → start the immersion operation → reach the immersion Immersion requirements → release the flooded oil → load it into a special transportation tool → transport it to the destruction process.

[0023] Put the carton filled with the product into the product containing device, and then put the containing device into the passivation liquid filling box (this box has been placed in the passivation device in advance), and then the operator evacuates from the passivation device operating room Inside, close the explosion-proof door. Open the passivation solution filling valve at the working position, so that the passivation solution flows from the passivation solution tank into the bottom of the ...

Abstract

The invention discloses a passivation method for waste initiating explosive devices, and relates to the technical field of passivation of primer and igniter cap type initiating explosive devices. The method comprises the following steps: extracting an oil product, forming an oil film on the surface of the waste product and the exposed sensitive medicament by adopting an immersion mode, and achieving the purpose of effectively passivating the friction, static electricity and impact sensitivity of the product by utilizing the characteristics of viscosity, difficulty in ignition at normal temperature and the like of the oil product. Passivating the immersed wastes, wherein the dose of all passivated products does not exceed 80% of the designed anti-explosion equivalent weight of the passivated anti-explosion room; after passivation is completed, oil filtering is carried out; a carrying device, a packaging device, a bearing device, an oil charging and discharging device and the like which are used in the passivation operation all adopt a structural design capable of enabling an oil product to smoothly immerse and flow out, so that safety accidents caused by the fact that high-sensitivity chemicals are detonated by sparks and heat generated by accidental collision in the passivation treatment process are avoided; except the one-time action of putting the product to be destroyed into the special containing appliance, the waste product is not directly contacted in the whole processes of transportation, soaking and filtering.

Description

technical field [0001] The invention belongs to the technical field of passivation of pyrotechnic products such as primers and caps, and in particular relates to a passivation method for waste pyrotechnic products. Background technique [0002] Primer and flash cap products are a large category of pyrotechnic products, and are the basic original components of bullets, shells and other products. It is characterized by sensitivity to impact, friction and static electricity. The original passivation method simply puts it into the destruction furnace for incineration, and does not pay attention to the passivation treatment before destruction. It is very easy to cause safety accidents due to impact, friction and static electricity during the handling of destruction and incineration work, and delivery. Contents of the invention [0003] In order to solve the defects and deficiencies of the prior art, the object of the present invention is to provide a passivation method for py...
