There are dozens of common types, including general-purpose plastics, engineering plastics, and specialty plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane; engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, and polycarbonate silicone; and specialty plastics include thermosetting plastics and functional polymer plastics. Medical PVC pellets are a type of plastic pellet. Currently, the production of medical PVC pellets has reached a high level of automation, and storage tanks are required for their production.

[0003] However, after storing medical PVC granules, the storage tanks currently used are usually vacuum-extracted by a negative pressure machine to achieve the purpose of moisture-proofing. However, when the medical PVC granules in the storage tank need to be used, the storage tank must be vacuum-treated again by the negative pressure machine after taking them out. This process not only consumes a lot of time, but also leads to unnecessary consumption of energy. Utility Model Content

At this time, the inside of the storage chamber 11 maintains a negative pressure state. When the material is taken out, the second sealing valve 62 in the discharge pipe 61 is closed, and the transfer chamber 12 is evacuated into a vacuum by the negative pressure machine 7, thereby reducing the vacuuming time and energy consumption, and solving the problem that when the medical PVC granules in the storage tank need to be used, the negative pressure machine 7 must be used again to vacuum the storage tank after taking it out. This process not only consumes a lot of time, but also leads to unnecessary energy consumption.

The lower end of the storage chamber 11 is fixedly connected to the conveying pipe 31, the upper end of the conveying pipe 31 passes through the transfer chamber 12, and the auger 32 is rotatably connected inside the conveying pipe 31. The lower end of the storage tank 1 is fixedly connected to the motor 33, and the output shaft end of the motor 33 passes through the interior of the storage chamber 11 and is fixedly connected to the lower end of the auger 32.

[0024] In this embodiment, the auger 32 is driven to rotate by the driving motor 33, and the rotating auger 32 moves the material inside the storage chamber 11 to the transfer chamber 12, thereby achieving a preliminary effect of transferring the material.

[0025] In a further embodiment, referring to Figure 2-Figure 3 The lower end of the storage tank 1 is fixedly connected to a sealing box 13 , and the motor 33 is located inside the sealing box 13 .

[0026] In this embodiment, by providing a seal and wrapping the motor 33 , on the one hand, the motor 33 is protected, and on the other hand, external gas is prevented from leaking into the storage tank 1 .
