Description

Technical Field

[0001] The utility model relates to the technical field of crushing devices, in particular to a crushing device for block phenolic resin. Background Art

[0002] Phenolic resin is mainly used in the manufacture of various plastics, coatings, adhesives and synthetic fibers, etc. From 1905 to 1909, L.H. Baekeland conducted systematic research on phenolic resin and its molding process. In 1910, the General Phenolic Resin Company was established at the Lurgis Factory in Berlin to realize industrial production. In 1911, J.W. Ellsworth proposed to cure thermoplastic phenolic resin with hexamethylenetetramine and obtained plastic products with good performance, which have been widely used. In 1969, fibers made from phenol-formaldehyde resin were developed by the Carborundum Company of the United States, and then put into production by the Kynol Company of Japan. Now the United States, the Soviet Union and China also produce it. The production of phenolic resin has not declined so far. In 1984, the world's total output was about 1946 kt, ranking first among thermosetting resins. When processing phenolic resin, it is necessary to crush the phenolic resin.

[0003] During the process of crushing phenolic resin, it is necessary to conduct two-layer filtration and screening on the phenolic resin. When conducting the second-layer filtration and screening, at this time the phenolic resin has been crushed very finely, and this will cause the filter screen openings to be blocked during filtration. Moreover, fine particles after crushing of phenolic resin will adhere to the inner wall of the conveying pipe when the phenolic resin passes through the filter screen and reaches the collection box. If not cleaned for a long time, this will lead to the blockage of the filter screen and the pipeline. Therefore, it is necessary to improve this situation. Summary of the Utility Model
