Description

Technical Field

[0001] The present invention relates to a gunpowder quantitative mixing device, belonging to the technical field of gunpowder quantitative mixing. Background Art

[0002] Solid propellant is an energetic composite material with specific properties. Its most important use is as an energy source and working medium in solid rocket and missile engines. When burning, it rapidly generates a large amount of high-temperature gas, and generates thrust through the expansion of the nozzle, converting the chemical energy of the propellant into the kinetic energy of rocket flight, thereby achieving the purpose of carrying and attacking and damaging. As the "heart" of solid rocket and missile engines, the quality of its performance directly affects the performance of rockets or missiles.

[0003] During the production process of propellant, it is necessary to mix gunpowder of various components. At present, there are still factories using manual semi-automatic mixing, with low mixing efficiency and difficult to achieve quantitative mixing.

[0004] Moreover, most current gunpowder mixing is carried out in an open environment. Due to the weak safety awareness of factory workers, if the operation is improper during the gunpowder mixing process, it is very easy for the gunpowder to spontaneously combust and cause an explosion accident. Summary of the Invention

[0005] The purpose of the present invention is to provide a gunpowder quantitative mixing device to solve the problems of low mixing efficiency and poor safety in traditional gunpowder mixing processes.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] A gunpowder quantitative mixing device of the present invention includes an upper support plate and a lower support plate horizontally fixed by columns, a set of loading hoppers fixed on the upper support plate, a set of pouring components correspondingly arranged around the upper plate surface of the lower support plate, a set of transfer and receiving components correspondingly arranged in the middle of the upper plate surface of the lower support plate, a stirring component arranged on the lower plate surface of the lower support plate, and a product receiving component arranged below the lower support plate;

[0008] The pouring component includes a telescopic cylinder on the upper plate surface of the lower support plate, a quantitative hopper hinged and installed at the upper end of the telescopic cylinder through a connecting rod, and an electronic scale arranged at the bottom of the inner cavity of the quantitative hopper;

[0009] The transfer and receiving component includes a receiving hopper and a guide pipe connected below the receiving hopper;

[0010] The stirring component includes a stirring cylinder, a rotating rod rotatably connected in the middle of the inner cavity of the stirring cylinder, stirring fins arranged on the side wall of the rotating rod, and a rotating rod driving component for driving the rotation of the rotating rod;

[0011] The product receiving assembly includes a turntable, a group of collecting cylinders arranged on the upper surface of the turntable, and a turntable driving assembly for driving the turntable to rotate;

[0012] Each metering hopper of the material pouring assembly is connected to each receiving hopper of the intermediate material receiving assembly through a rotating shaft. When the telescopic rod of the telescopic cylinder is extended, the metering hopper flips to the corresponding side of the receiving hopper; the lower ends of the material guide pipes of the intermediate material receiving assembly are inserted into the upper end of the inner cavity of the mixing drum; the turntable driving assembly drives the turntable to rotate, so that each collecting drum is aligned with the bottom of the mixing drum in turn;

[0013] A discharge valve is provided at the discharge port of each loading hopper, and the discharge valve is connected to the electronic scale circuit in the corresponding quantitative hopper below. When the electronic scale reaches a weight threshold, the corresponding discharge valve is controlled to close.

[0014] Working process

[0015] When the gunpowder is quantitatively mixed, firstly, gunpowder of different components is loaded into different loading hoppers respectively, and the discharge valve is opened, and the gunpowder in the loading hopper will fall into the corresponding quantitative hopper, and the electronic scale weighs the gunpowder in the quantitative hopper. When the weight of the gunpowder reaches a predetermined weight, the corresponding discharge valve is controlled to close, so that each component of the gunpowder is quantitatively taken, and the rotating rod driving assembly is turned on; then each telescopic cylinder simultaneously controls its telescopic rod to extend, so that all the quantitative hoppers are flipped toward the corresponding receiving hopper side, thereby guiding the gunpowder in the quantitative hopper into the corresponding receiving hopper, and the gunpowder entering the receiving hopper will enter from the upper end of the mixing drum through the corresponding material guide pipe; the rotating rod driving assembly drives the stirring wing to rotate through the rotating rod, stirs the respective component gunpowders entering the mixing drum, and the mixed gunpowder falls into the collecting drum.

[0016] The turntable is driven to rotate by the turntable driving assembly, so that the next empty collecting cylinder is rotated to the bottom of the mixing cylinder, and the above-mentioned medicine mixing process can be repeated until all the collecting cylinders are fully filled.

[0017] Beneficial Effects

[0018] The gunpowder quantitative mixing device of the present invention realizes quantitative mixing of various gunpowder components without the need for manual operation, effectively improves mixing efficiency, greatly reduces the probability of misoperation and the influence of external factors, and thus further improves safety.
