Embodiment Construction
[0047] This embodiment is a method for quantitatively feeding energetic liquid raw materials.
[0048] The feeding device adopted adopts the existing technology, including a ton bag 1, a single-girder crane, multiple ton bag weighing tooling 2, a weighing platform 3, a mixing pot 7 and a second-floor operation platform 4. Among them, the ton bag 1 is used for packaging energetic adhesives to realize large-capacity and overall transfer; the platform 4 on the second floor is used for the overall weighing of the ton bag 1, feeding and fixed operation area.
[0049] The concrete process of this embodiment is:
[0050] Step 1: Preparation of ton bag weighing tooling:
[0051] The weighing platform of Zhongjiali Weighing Equipment System Co., Ltd. and the sensors and instruments of Sartorius Industrial Weighing Equipment Co., Ltd. are used. The weighing range of the weighing platform 3 is 1500-2000kg, the verification division value e=200g, and the display division value d=200g. ...

According to a quantitative feeding method and tool for the energetic liquid raw materials, a ton bag barrel weighing tool is utilized, and the method of packaging ton bag barrel overall weighing, rapid discharging, decrement method charging, flow guide pipe efficient charging and real-time control is adopted. The problems of volatilization of key components, change of physical and chemical properties of raw materials, adhesion and dripping of dangerous components, low manual operation efficiency and the like are effectively solved, and potential quality hazards of key component failure and sudden change of physical and chemical properties, health hazards of human occupational health and potential safety hazards of dangerous operation are avoided. The method and tool are suitable for weighing and feeding energetic liquid raw materials of propellants of various models in the field of solid rocket engine production, and can be popularized to related fields such as quantitative addition of bulk liquid components.
Description
technical field [0001] The invention belongs to the technical field of solid rocket motors, in particular to a method for real-time weighing and quantitative feeding of energetic liquid raw materials for propellants and a feeding tool. Background technique [0002] Energetic liquid raw materials are mainly represented by nitrate plasticized polyether adhesives, which have been used in large quantities, also known as NEPE adhesives; this type of adhesive is a polymer liquid prepolymer. The elastic matrix constituting the propellant is also the fuel with specific energy, which occupies an extremely important position in all components of the propellant. The solid rocket propellant produced with NEPE binder as raw material is also called NEPE propellant, which has the advantages of high energy and good mechanical properties, and its energy performance and mechanical properties exceed the original various propulsion Propellants are the most advanced class of propellants that ha...
