Problems solved by technology

At present, there are two main methods for crushing shaped powder columns / blocks: one is to use a crocodile crusher for crushing; the other is to use a roll crusher for crushing. These two crushing methods have two major disadvantages: 1. Its working principle is to give the explosive column / block a rapid high impact pressure greater than its compressive strength to make it rupture. Since the explosive is a substance that easily forms hot spots and detonation under the action of external impact force, therefore Its risk is very high, and explosive explosions often occur during the crushing process, causing casualties and equipment damage. Craft brings great difficulty
In view of the above two shortcomings, it is generally impossible to effectively recycle and utilize the formed grains / blocks, but directly burn them or detonate them, which not only causes huge economic losses, but also causes environmental pollution and damage

Embodiment 1

[0027] refer to Figure 1 to Figure 8 , this embodiment gives a specific structure and manufacturing and assembly example of a shaped explosive column / block mechanical crushing device. The shaped explosive column / block mechanical crushing device at least includes a feeding cylinder 1 , a crushing cartridge 2 , a variable pitch worm 3 , a sieve plate 4 , a feeding cylinder 5 and a bracket 6 .

[0028] see figure 2 , There are flanges at both ends of the feeding cylinder 1, the upper end is an open cylinder, and the lower end is in the shape of an inverted basin. The specific structure includes: an upper flange 1-1, an upper straight cylinder 1-2, a feed inlet 1-3, a lower flange 1-4, a rolling bearing 1-5, a bearing frame 1-6 and fastening bolts 1-7. The upper straight cylinder 1-2 and the feed inlet 1-3 are integrally cast with cast steel, with a thickness of 8mm to 10mm; the upper straight cylinder 1-2 has a height of 100mm, an outer diameter of 170mm, and the height of th...

Embodiment 2

[0038] This embodiment provides the press-packed explosive column 10 by using the shaped explosive column / block mechanical crushing device prepared in Example 1. # -159 broken instances.

[0039] The used shaped explosive 10 of the present embodiment # The charge of -159 is cylindrical in shape with a size of 120mm in diameter and 135mm in height.

[0040] Before breaking the powder column, inject tap water into the water bath, and the water surface height reaches the upper end surface of the feed port 1-3, and 10 # -159 explosive column is put into the crushed cartridge 2 through the feed port 1-3, turn on the power supply of the explosion-proof speed-regulating motor, adjust the motor speed to 5rad / min~10rad / min, the rotation of the explosion-proof speed-regulating motor drives the variable-pitch worm 3 at the same speed Rotate, so that the drug column is broken under the extrusion action of the variable pitch worm 3 and the barrel 2-2 of the crushing cartridge 2. Through ...

Abstract

The invention discloses a forming explosive column / block mechanical disruption device which mainly comprises a charge-in barrel, a disruption barrel, a distance-changeable worm, a sieve plate, a material-collecting barrel and a support, when a disruption explosive column / block is completely immerged in the water environment, a speed-regulating motor is used for driving the distance-changeable worm to slowly rotate. Pressure capable of ensuring that the explosive column / block reaches the disruption intensity is acted on the explosive column / block according to the squeezing and conveying principle of a screw, and accordingly the explosive column / block is crumbled. Rotating of the distance-changeable can gradually disrupt an explosive block into small uniform explosive partials from above down in a gradation mode, the small explosive partials are conveyed to the sieve plate connected with the low end of the disruption barrel, and the sizes of the finally obtained explosive partials are about 2mm-4mm by sieving of the sieve plate. The sizes of the explosive partials after being disrupted can be controlled through replacement of sieve plate s with different sizes of hole space, and control of particle size after cracking of the disruption partials and uniformity of granularity of the explosive column / block are achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and relates to a mechanical crushing device, in particular to a shaped explosive column / block mechanical crushing device. Background technique [0002] The recycling of waste propellant and explosives has always been a hot and difficult point of research at home and abroad, especially for the powder column / block that has been pressed, it must be broken into fine particles with a relatively uniform particle size before recycling. At present, there are two main methods for crushing shaped powder columns / blocks: one is to use a crocodile crusher for crushing; the other is to use a roll crusher for crushing. These two crushing methods have two major disadvantages: 1. Its working principle is to give the explosive column / block a rapid high impact pressure greater than its compressive strength to make it rupture. Since the explosive is a substance that easily forms hot spots and detona...
