Description

Technical Field

[0001] The utility model belongs to the technical field of polyvinyl alcohol grinding, and relates to a grinding machine with reduced floor space. Background Art

[0002] Polyvinyl alcohol (PVA) is an important chemical raw material widely used in coatings, adhesives, fibers and other fields. Polyvinyl alcohol powder is a widely used water-soluble polymer with performance between plastics and rubbers. Through grinding, the particle size of polyvinyl alcohol becomes smaller, which can increase its dispersibility and solubility in the solution, so that it can be better mixed with other substances. In some application fields, such as paper coating, adhesive preparation, etc., the fineness and uniformity of polyvinyl alcohol powder are crucial to its performance. Through grinding, the fineness and uniformity of polyvinyl alcohol powder can be improved, thereby improving its application performance. During the grinding process, if it cannot be cleaned quickly, it may cause a series of problems, as follows:

[0003] As the PVA powder accumulates during the grinding process, the mill's processing capacity will gradually decrease. This is because the accumulation of powder will reduce the internal space of the mill, which will reduce the grinding efficiency. In addition, the accumulated powder may cause blockages, increasing the frequency of equipment maintenance, further affecting production efficiency.

[0004] Due to the accumulation of PVA powder, the temperature and pressure of the mill may change, which may affect the quality of the product. For example, too high temperature may cause the degradation of PVA, while changes in pressure may affect the particle size and distribution of the powder. These factors will make the quality of the product unstable.

[0005] The metal parts and bearings inside the mill may wear out under the long-term and continuous impact of polyvinyl alcohol powder. This wear not only shortens the service life of the equipment, but may also cause equipment failure.

[0006] As PVA powder accumulates, the internal temperature and pressure of the mill may increase, which may cause safety issues such as fire and explosion. Therefore, for the PVA grinding process, it is crucial to keep the equipment clean and well maintained.

[0007] If the polyvinyl alcohol powder is not cleaned up in time, it may cause environmental pollution. The leakage and discharge of the powder will not only pollute the surrounding environment, but also may affect the health of workers.

[0008] Therefore, in order to ensure the smooth progress of the polyvinyl alcohol grinding process and the stability of production, effective measures must be taken to solve the cleaning problem. This includes regular cleaning of equipment, use of appropriate cleaning tools, and strengthening of equipment maintenance. At the same time, it is also necessary to pay attention to production safety and environmental protection to ensure the sustainable development of the polyvinyl alcohol grinding process. Therefore, a grinding machine with a reduced footprint is urgently needed to solve the above problems. Utility Model Content
