Embodiment Construction

[0016] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] This embodiment proposes a kind of internal screw quantitative feeding device, its structure is as follows figure 1 shown. The device comprises a bracket 1, a motor mount 2, a motor and a reducer 3, a rear bearing 4, a silo 5, a silo cover 6, a barrel 7, a front bearing 8 and a baffle plate 9.

[0018] Wherein, the barrel 7 is divided into a cone section and a straight section, and the inner wall of the barrel 7 is provided with a plurality of spiral grooves. The cone section of the barrel 7 is fixedly connected with the feed bin 5 through bolts, and the feed bin 5 is installed on the support 1 through the rear bearing 4; the straight section of the feed barrel 7 is installed on the support 1 through the front b...

Abstract

The invention belongs to the technical field of explosive feeding equipment, and particularly relates to an internal screw quantitative feeding device for uniform-speed conveying of explosive powder.The feeding device comprises a support frame, a motor mounting seat, a motor, a speed reducer, a rear bearing, a stock bin, a stock bin lid, a material barrel, a front bearing and a baffle. The internal screw quantitative feeding device provided by the invention has the benefits that by utilizing spiral grooves in the inner wall of the material barrel and relying on the gravity of materials, quantitative forward conveying of the materials when the material barrel rotates is realized, and the forward conveying speed of the materials is controlled by controlling the rotating speed of the material barrel, therefore, the mechanical stimuli such as extrusion and impact of the feeding device on the materials are avoided, and the safety is improved; the feeding speed can be controlled by controlling the rotating speed of the material barrel and has nothing to do with the amount of the materials in the stock bin; the problem of material bridging in the stock bin of an existing feeding device can be solved.

Description

technical field [0001] The invention belongs to the technical field of propellant and explosive feeding equipment, and in particular relates to an internal spiral quantitative feeding device for conveying propellant and explosive powder at a uniform speed. Background technique [0002] In the production process of explosives, it is often necessary to transport and add various powdered raw materials of explosives to the processing equipment at a uniform speed, so as to produce the required products according to the ratio of each component in the formula. In the current explosives production industry, commonly used powdered explosives feeding methods include single-screw feeding, twin-screw feeding, vibration feeding, etc. Most of the raw materials used in the explosives production industry have high mechanical sensitivity, and will be dangerous when encountering certain stimuli such as extrusion, friction, impact, etc., but the feeding technology and devices currently used ha...
