Problems solved by technology

In the charging process, if manual loading is used, although the physical structure of the emulsion explosive can be guaranteed not to be damaged, the efficiency is low, especially there is a great potential safety hazard
However, if the existing machinery is used for filling, the physical structure of the emulsion explosive may be destroyed, resulting in a decrease in the performance of the explosive, or even complete failure; and the existing mechanical filling is difficult to meet the safety requirements of the emulsion explosive charge

Abstract

The invention provides an emulsion explosive charging device which comprises a pump body. The pump body comprises a pump cover (1), a pump bottom (2) and a pump body inner sleeve (3), wherein a rotor(4) is arranged in the pump body inner sleeve (3), the rotor (4) is peripherally provided with a guiding plate (5), the guiding plate (5) divides the inner cavity of the pump body inner sleeve into anupper-portion material conveying area (6) and a lower-portion negative pressure area (7), the lower-portion negative pressure area (7) is connected with a negative pressure device, the upper-portionmaterial conveying area is provided with a material conveying port and a material output port, the guiding plate is peripherally provided with a plurality of guiding grooves (8) distributed radially,each guiding groove is provided with a vertical sliding plate (9), the pump cover is provided with an upper-portion guiding curved surface (10) extending towards the upper-portion material conveying area, the pump bottom is provided with a lower guiding curved surface (11) extending towards the lower-portion negative pressure area, and the upper-portion guiding curved surface and the lower guidingcurved surface make the inner cavity of the pump body inner sleeve to form high-point and low-point annular cavities. The emulsion explosive charging device achieves low shear, low pulse and high conveying and can effectively reduce friction and impact.

Description

technical field [0001] The invention belongs to the technical field of emulsion explosive charging, in particular to an emulsion explosive charging device. Background technique [0002] Colloidal emulsion explosive is a new type of industrial explosive with special physical structure. In the charging process, if manual loading is used, although it can ensure that the physical structure of the emulsion explosive is not destroyed, the efficiency is low, and there is a great potential safety hazard in particular. However, if the existing machinery is used for loading, the physical structure of the emulsion explosive may be destroyed, resulting in a decrease in the performance of the explosive, or even complete failure; and the existing mechanical loading is difficult to meet the safety requirements of the emulsion explosive charge. Therefore, how to provide an emulsion explosive charging pump with simple structure, high loading efficiency and safety has become the focus of att...
