Automatic sticky liquid scale material-receiving tray capable of preventing adhesive sagging

Abstract

The utility model discloses an automatic sticky liquid scale material-receiving tray capable of preventing sticky liquid sagging. The material-receiving tray comprises a material bearing tray and a cylinder body, and a port at the top end of the barrel is a horn mouth. The material bearing tray is sleeved and fixed on the outer circumference of the cylinder body. Drainage through holes are uniformly distributed on the outer circumference of the cylinder body and are positioned above the root of the material bearing tray. Sticky liquid flowing down linearly is cut off through the horn mouth located at the top end of the cylinder body and flows into the material-receiving tray along with the inner wall of the horn mouth. Sticky liquid adhered to the outer wall of the horn mouth at the top end of the cylinder body is collected through the material bearing tray, and the collected sticky liquid is guided into the cylinder body of the material-receiving tray through the drainage through holes. According to the invention, the propellant weighing accuracy can be guaranteed, sticky liquid sagging on the wall of the material-receiving tray is recycled, sagging waste of raw materials is avoided, and the beneficial effect of saving the propellant raw materials is achieved.

Description

technical field [0001] The invention relates to the field of weighing solid propellant raw materials, in particular to an anti-slime flow-mounted feeding tray of a viscous automatic weighing scale for propellant. Background technique [0002] Solid rocket propellant raw materials can be divided into three categories according to their physical characteristics: liquid, powder and viscous liquid. Among them, the viscous liquid has been automatically and accurately weighed, and the weighing device used is an automatic mucus scale. [0003] The weighing method adopted by the automatic slime scale is the first increase and then the subtraction method, that is, the slime is added to the weighing storage tank through the automatic feeding method through the incremental method, and the electronic scale on the weighing storage tank reads the feeding process and adds The quality of the slime requires that the quality of the slime added to the weighing storage tank should be greater t...
