A charging device for high-viscosity liquid charge

Abstract

A collecting device used during charging of high-viscosity liquid comprises a rotating cylinder, a mounting plate, a shaft sleeve seat, a shaft and a rotating basin stand, wherein the shaft sleeve seat is fixed on the lower surface of the mounting plate through a flange; a central hole of the shaft sleeve seat and a shaft penetrating hole in the mounting hole are concentric; the rotating cylinder is arranged on the upper surface of the mounting plate; an outputting end of the rotating cylinder is fixedly connected with one end of the shaft; the other end of the shaft penetrates in the shaft penetrating hole in the mounting plate, is fixed on the shaft sleeve seat on the lower surface of the mounting plate, is arranged in a shaft hole in the rotating basin stand and is fixedly connected with the rotating basin stand; and the mounting plate is fixed on a flange at the position of an outlet of a slurry pot. When used, the collecting device is hung on the lower portion of a hopper, at the later period of feeding, a basin supporting frame drives a collecting basin to move to a position below a discharging valve by action of the rotating cylinder, continuous dripping materials are cut off, a small amount of dripping high-viscosity liquid is collected in the collecting basin, the weighing precision is guaranteed, and the circumstance that the high-viscosity liquid drips on the ground and health of operators is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of solid rocket motor charging, in particular to a feeding device for an automatic weighing system of energetic high-viscosity liquid materials in the preparation process of solid propellant raw materials. Background technique [0002] High-viscosity liquids refer to energetic liquid materials with a viscosity of 4mPa·S, which are the main raw materials of solid rocket motors. When weighing high-viscosity liquid materials of solid propellants, automatic viscous scales are often used for weighing: the weighing system is controlled by an industrial control computer, and the viscous materials in the viscous automatic scale hopper pass through the fast discharge valve, slow discharge valve and so on. The material is unloaded into the mixing pot under the scale body by weighing by subtraction method. The specific weighing method is: a certain amount of viscous material is stored in the viscous hopper, when the m...
