Problems solved by technology

[0002] Powdered explosives are sensitive to humidity, and the humidity of powdered explosives must be well controlled during the production process. At present, the main method of controlling the humidity of powdered explosives is to add powdered explosive additives with a quantitative screw machine, and powdered explosive additives are very fine The granules need only a little steam to be damp and sticky. During the addition process of the quantitative screw machine, powdery explosive additives often block the outlet of the quantitative screw machine due to moisture, making the addition of additives uneven, which seriously affects the powdery explosives. product quality

Embodiment Construction

[0009] Such as figure 1 Among them, the uniform feeding device for powdery explosive additives includes a quantitative screw machine 1 and a conical nozzle 2 located at the discharge port 3 of the quantitative screw machine 1. The discharge port 3 of the quantitative screw machine 1 passes through the sealing assembly 4 and the conical nozzle 2. Connected, the conical nozzle 2 is provided with a high-pressure air intake device 5; there are two high-pressure air intake devices 5, which are horizontally and symmetrically distributed on the conical nozzle 2.

[0010] The working principle of the present invention: when the powdery explosive additive is added, the quantitative screw machine 1 quantitatively transmits the powdery explosive additive into the conical nozzle 2 through the discharge port 3, and at the same time passes the high-pressure air through the high-pressure air provided on the conical nozzle 2 The air intake device 5 is input into the conical nozzle 2, and the ...

Abstract

The invention discloses a uniform feeding device for a powdery explosive additive. The uniform feeding device for the powdery explosive additive comprises a quantitative screw machine and a conical spray nozzle, wherein the conical spray nozzle is arranged at a material outlet of the quantitative screw machine; the conical spray nozzle is provided with a high-pressure air inlet. According to the device, the additives can be uniformly fed in a powdery explosive.

Description

technical field [0001] The invention relates to a powdery explosive additive feeding device, in particular to a powdery explosive additive uniform feeding device. Background technique [0002] Powdered explosives are sensitive to humidity, and the humidity of powdered explosives must be well controlled during the production process. At present, the main method of controlling the humidity of powdered explosives is to add powdered explosive additives with a quantitative screw machine, and powdered explosive additives are very fine The granules need only a little steam to be damp and sticky. During the addition process of the quantitative screw machine, powdery explosive additives often block the outlet of the quantitative screw machine due to moisture, making the addition of additives uneven, which seriously affects the powdery explosives. product quality. Contents of the invention [0003] The technical problem to be solved by the invention is to overcome the influence of ...
