Static sensitization device and its cutting body

Abstract

The invention discloses a static sensitizing device which can be produced continuously, and a cutting blade body of the static sensitizing device. The static sensitizing device comprises an inlet, an outlet, and a channel between the inlet and the outlet, wherein the channel from the inlet to the outlet comprises at least two first units; cutting blades are distributed at intervals in the first units, and the distribution density of the cutting blades is determined according to technical requirements; a second unit is arranged between every two adjacent first units and comprises at least one layer of grids; and the quantity of meshes of the grids, the number of the layers of the grids, and the spacing of the grids are determined according to the technical requirements. The cutting blade body is I-shaped, and provided with four edges of which a plane is different from a plane of the centre line of an axle hole; and each edge is cut to form each cutting blade. With adoption of the static sensitizing device, an emulsifying base and foaming agent can be uniformly mixed, the sensitizing process can be continuously carried out, the technical quality index of emulsion explosives can be completely met, and explosion accidents caused by agitating at a high speed of equipment can be avoided; and the static sensitizing device is particularly suitable for the field of emulsion explosive production.

Description

technical field [0001] The invention relates to the field of emulsion explosive production equipment, in particular to an emulsion explosive static sensitization device. Background technique [0002] In the production process of emulsion explosives, it is necessary to chemically sensitize the semi-finished emulsion, which is usually called "emulsion matrix", so that it can be transformed into the emulsion explosive required by the process. The sensitization mixer is one of the important equipments for domestic production of emulsion explosives. At present, in explosives production enterprises, a sensitization mixer is generally used to stir and shear the emulsified matrix to make it sensitized at a low temperature of 40°-50°. The stirring can form the emulsion explosive required by the process. Since the blades of the agitator are in contact with the emulsified matrix during high-speed rotation, the emulsion explosive gradually transformed from the emulsified matrix may be...

AI Technical Summary

Problems solved by technology

Since the blades of the agitator are in contact with the emulsified matrix during high-speed rotation, the emulsion explosive gradually transformed from the emulsified matrix may be overheated by the impact and friction of the blades, which may easily cause explosion accidents

It is also for this reason that the mixer cannot work continuously, but after one tank of emulsion explosive is stirred, it is released before stirring another tank, and the production efficiency is low.
