Description

Technical Field

[0001] The utility model relates to the field of silicon carbide micropowder, in particular to a filtering structure used for pressure filtration of silicon carbide micropowder. Background Art

[0002] Silicon carbide micropowder refers to micron-sized silicon carbide powder that is ultra-finely ground and graded using JZFZ equipment. Silicon carbide micropowders are primarily 1200# and 1500#. Because silicon carbide micropowders are primarily used in the abrasive industry, special requirements apply to their grading. Large particles must be avoided within the powder. Therefore, to meet international and domestic product requirements, JZF grading equipment is generally used for high-precision grading. After washing, silicon carbide micropowders require a filter press to remove moisture. However, current filter presses often clog the filter plates with silicon carbide micropowder due to repeated filtration, hindering water extraction and making disassembly and cleaning time-consuming.
