Embodiment Construction

[0021] This embodiment is a dynamic weighing and feeding device for a spherical oxidant, which includes a weighing hopper 2, a mass scale 3, a feeding cart 6 and a feeding valve. The spherical oxidizer dynamic weighing and feeding device is obtained after improving the prior art. Wherein, the discharge port of the weighing hopper 2 is communicated with the feed port of the transport truck 6 through the discharge pipeline, and an adapter plate 7 is fixed on the discharge port of the weighing hopper 2, and there are two A discharge pipe interface is respectively connected with one end of the first discharge pipe 8 and the second discharge pipe 9 located below the adapter plate. The other ends of the first discharge pipeline 8 and the second discharge pipeline 9 are respectively connected to the feed port of the transport truck 6 . The pipe diameter of the first discharge pipeline: the pipe diameter of the second discharge pipeline=3:1.

[0022] The feed valve includes a first ...

Abstract

The invention provides a dynamic weighing and feeding device for a spherical oxidant and a control method. The dynamic weighing and feeding device adopts the structure that the discharge opening of a weighing hopper is communicated with the feed opening of a material conveying wagon, a changeover panel is fixed to the discharge opening of the weighing hopper and provided with two discharge pipeline connectors which are respectively connected with one end of a first discharge pipeline and one end of a second discharge pipeline below the changeover panel, the other end of the first discharge pipeline and the other end of the second discharge pipeline are respectively connected with the feed opening of the material conveying wagon, the scale of the pipe diameter of the first discharge pipeline to the pipe diameter of the second discharge pipeline is 3: 1, a feeding valve is mounted on each of the two discharge pipelines, and the two feeding valves are respectively used for rapidly feeding and accurately controlling the later-period feeding quantity. The dynamic weighing and feeding device ensures that an operator in a control cabin away from the weighing site can achieve automatic weighing, improves the working conditions, eliminates potential safety hazards and effectively improves the work efficiency.

Description

technical field [0001] The invention relates to the automatic control of the charging process of solid rockets, in particular to an automatic control method for dynamic weighing of a spherical oxidizer. Background technique [0002] Spherical oxidizer is an important component of solid rocket motor propellant. The mass of spherical oxidant accounts for 47% of the total mass of the propellant, and this percentage is fixed. Higher or lower than this mass percentage will affect the performance of the propellant , thereby affecting the performance of the rocket. Therefore, it is necessary to accurately weigh the spherical oxidant when producing solid rocket motor propellants. [0003] The spherical oxidizer referred to in this system is ammonium perchlorate spherical particles covered by the surface coating agent-sodium dodecylsulfonate. Ammonium perchlorate is a white orthorhombic crystal at room temperature, and changes from an orthorhombic crystal to a cubic crystal at 240°...
