The utility model relates to the technical field of
propellant buffer tank supplementation, and discloses a
propellant buffer tank supplementation device which comprises a base, a material taking
barrel is arranged on the base, a feeding port is formed in the top of the material taking
barrel, end covers are arranged on the two sides of the material taking
barrel, and a first supplementation
pipe and a second supplementation
pipe are arranged on the end covers respectively. A material suction
assembly is arranged in the material taking cylinder and comprises a motor, the output end of the motor is connected with a main belt wheel, an auxiliary belt wheel is arranged on the opposite side of the main belt wheel, a rotating cylinder is arranged in a shaft hole of the auxiliary belt wheel and located in the material taking cylinder, a plurality of blades are arranged outside the rotating cylinder, and the auxiliary belt wheel is connected with the main belt wheel through a leather strip. The arranged material suction
assembly is driven by a motor, a rotating cylinder is driven by a main belt wheel and an auxiliary belt wheel to rotate in a material taking cylinder, propellants are pumped out through blades and supplemented into a
buffer tank through a supplementing
pipe, and rapid and efficient supplementing is achieved. Sealing rubber strips on the edges of the blades are attached to the inner wall of the material taking barrel, sealing performance is improved, and leakage is reduced. And the filter
cartridge filters impurities to ensure the purity of the
propellant. The device is compact in structure, easy and convenient to operate and high in supplementing efficiency, and the requirement for efficient and stable supplementing of the propellant buffer tank is met.
