Description

Technical Field

[0001] This utility model relates to the field of PVC technology, specifically to an anti-sticking device for the production of PVC heat stabilizers. Background Technology

[0002] Polyvinyl chloride (PVC) is the second most produced general-purpose plastic after polyethylene (PE). It possesses advantages such as self-extinguishing properties, flame retardancy, wear resistance, high strength, good electrical insulation, and chemical stability, and is inexpensive. It is widely used in industry, agriculture, defense, and construction. However, PVC has a unique structure; it is processed under high temperature and high shear conditions, which easily leads to the removal of HCl from the molecules, causing polymer degradation. This results in discoloration and a decrease in the mechanical properties of the finished product, affecting its service life. Therefore, heat stabilizers are needed to increase its stability. In the processing of PVC heat stabilizers, raw materials are stirred, filtered, dried, and pulverized to produce the finished product. The raw materials for PVC heat stabilizers are various metal blocks, such as zinc and lead blocks, which are processed into powder. When this powder is conveyed by a conveying device, it often adheres to the rotating shaft of the conveying device, accumulating and forming lumps. This severely affects the conveying process, reduces material quality, and the falling lumps may block the discharge port, affecting the normal operation of the equipment.

[0003] For example, CN205132148U discloses an anti-sticking device for PVC heat stabilizer production, belonging to the field of chemical equipment. It includes a hollow tank and a push rod; the tank is horizontally positioned with a discharge port at the bottom, and a rotating shaft inside the tank with rotating blades; one end of the rotating shaft extends beyond the front end of the tank; the push rod is a long rod-shaped structure, with one end connected to the end of the rotating shaft extending beyond the front end of the tank, and the length direction of the push rod is perpendicular to the axis of the rotating shaft; a cantilever beam parallel to the rotating shaft is fixed to the upper part of the front end of the tank, and a striking hammer is suspended from the front end of the cantilever beam; the striking hammer is located on the same side of the push rod and the rotating shaft. This invention can prevent materials from sticking to the rotating shaft, making it less prone to clumping and clogging the discharge port, ensuring the normal operation of the device and improving product quality.

[0004] However, in actual use, it was found that the surface of the tank lacked heating and cooling structural components, which reduced the production efficiency of the equipment. Utility Model Content
