Powdered ammonium nitrate explosive waste roll automatic stripping recovery device

Abstract

The invention discloses an automatic stripping and recycling device for waste cartridges of powder ammonium nitrate explosives. The device comprises a rack, a charging hopper, a motor, a transmission device, a paper shredding device, an explosive guiding board, a vibration device, a shaft coupler and an explosive screening device, wherein the charging hopper is arranged above the paper shredding device; the motor is connected with the paper shredding device by virtue of the transmission device and also connected with the explosive screening device by virtue of the shaft coupler; the upper end of the explosive guiding board is arranged on the rack by virtue of a rotary pin; the explosive guiding board is arranged aslant; the vibration device is arranged under the explosive guiding board; the lower end of the explosive guiding board extends into a drum screen frame of the explosive screening device; an explosive powder outlet and a waste paper outlet are formed in the rack which is arranged under the drum screen frame. The manual stripping and recycling of the waste cartridges of the powder ammonium nitrate explosives is replaced by the automatic stripping and recycling device for the waste cartridges of the powder ammonium nitrate explosives, so that the working intensity of operators is reduced to the great extent, the time and the labor are reduced, the production efficiency can be improved, the production cost is reduced, and the device is safely operated.

Description

technical field [0001] The invention relates to the technical field of ammonium nitrate explosive production, in particular to an automatic stripping and recovery device for powdered ammonium nitrate explosive waste coils. Background technique [0002] Powdered ammonium nitrate explosive has a series of advantages such as simple composition, easy manufacture, stable performance, high power, low cost, and no TNT, so it is welcomed by users. The explosives are generally packed into φ32mm, φ35mm and φ38mm rolls, and the material of the rolls is wax-impregnated paper rolls. However, due to improper operation or the impact of external forces during the production of packaging, some medicine rolls with damaged packaging often occur. In order to adapt to the technical progress guidance of the civilian explosives industry in the direction of safety, cleanliness, and conservation, according to the treatment process for damaged rolls of expanded ammonium nitrate explosives, it is nec...

Problems solved by technology

[0003] At present, the stripping, recycling and reuse of powdered ammonium nitrate explosive waste rolls is usually done by the operator using a blade to cut open the waste roll and sieve it before recycling. This method is time-consuming, laborious, and inefficient. Safety

In the Chinese patent with the authorized notification number CN202705264U, a device for dismantling unqualified emulsion explosive coils is disclosed, including a frame, a demolition tube, a push plate, a thrust device and a demolition tool. The roll is pushed to the fixed breaking knife to break open the waste medicine roll, and the thrust device is pushed forward to break a waste medicine roll and needs to be retracted and returned to its original position, that is, one working cycle (forward push and backward retraction) can only break open A waste medicine volume, although this breaking device can break the waste medicine volume, but there are still shortcomings: 1. Only one waste medicine volume can be broken in one working cycle, and the work efficiency is not high; 2. After breaking open The waste medicine roll still needs to shake off the explosives in the medicine roll by manual operation, which is time-consuming, laborious and unsafe to operate; 3. Use the thrust device to push the waste medicine roll to the fixed demolition tool to break the waste medicine roll, and the explosive is subjected to impact load Strong force, suitable for colloidal emulsion explosives with good fluidity, not suitable for powdery ammonium nitrate explosives, there are potential safety hazards
