Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to a PVC storage tank for the chemical industry. Background Technology

[0002] PVC storage tanks are containers specifically designed for storing PVC (polyvinyl chloride) and related chemicals. These tanks are typically made of plastic materials such as polypropylene or polyethylene to ensure good corrosion resistance and safety against chemicals.

[0003] Existing PVC storage tanks in the chemical industry are problematic because PVC material itself has a certain degree of viscosity and poor flowability. During storage, it is prone to clumping or adhering to the discharge port, which may lead to discharge blockage. Once the discharge port is blocked, manual unblocking is required, which not only increases the labor intensity of workers but also affects the smoothness of the production process. Discharge blockage of PVC storage tanks not only affects production efficiency and increases production costs but may also have an adverse impact on product quality. Utility Model Content

[0004] In view of the technical problem that existing PVC storage tanks in the chemical industry are prone to clumping or adhering to the discharge port during storage due to the inherent viscosity and poor flowability of PVC material, which may lead to discharge blockage, this utility model provides a PVC storage tank for the chemical industry.

[0005] The technical solution of this utility model is as follows: a PVC storage tank for the chemical industry, comprising a storage tank body, a drive motor, and a baffle assembly; a support column for supporting the storage tank body is provided at the lower end of the storage tank body, a discharge pipe for discharging material is provided at the lower end of the storage tank body, a feed pipe is provided at the upper end of the storage tank body, a sealing cap is provided on the outside of the feed pipe, a baffle assembly is provided on one side of the discharge pipe, a drive motor is provided at the upper end of the storage tank body, a first bevel gear is provided at the output end of the drive motor, a second bevel gear is provided on one side of the first bevel gear, the second bevel gear meshes with the first bevel gear, a first rotating rod is provided on the inner side of the second bevel gear, a stirring blade for agitating PVC is provided on the outer side of the first rotating rod, a third bevel gear is provided on one side of the first bevel gear, the third bevel gear meshes with the first bevel gear, a second rotating rod is provided on one side of the third bevel gear, and a spiral blade for preventing PVC blockage during discharge is provided on one side of the second rotating rod.

[0006] Preferably, a groove is provided at the corresponding position of the storage tank body and the first rotating rod, and the first rotating rod is rotatably connected inside the groove of the storage tank body.

[0011] Preferably, a groove is provided at the corresponding position of the discharge pipe and the third rotating rod, and the third rotating rod is rotatably connected inside the groove of the discharge pipe.

[0012] The beneficial effects of this invention are as follows: Compared with traditional PVC storage tanks in the chemical industry, PVC material itself has certain viscosity and poor flowability, which can easily cause it to clump or adhere to the discharge port during storage, potentially leading to discharge blockage. This device, by starting the drive motor, drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the first rotating rod to rotate, which in turn drives the stirring blade to rotate, thereby agitating the PVC inside the storage tank. The first bevel gear drives the third bevel gear to rotate, which in turn drives the second rotating rod to rotate, which in turn drives the spiral blade to rotate, which in turn drives the PVC to be discharged from the discharge pipe. This effectively prevents material blockage during storage and transportation, ensuring the continuity and stability of the production process. Attached Figure Description
