Grooved perforated porcelain ball

Abstract

The utility model relates to the technical field of perforated porcelain balls, in particular to a grooved perforated porcelain ball which comprises a ball body, a first wear-resistant layer is coated on the outer surface of the ball body, a plurality of left through holes are formed in the left portion of the upper end of the ball body in a penetrating mode, a plurality of right through holes are formed in the right portion of the upper end of the ball body in a penetrating mode, and an upper groove is formed in the upper portion of the outer surface of the ball body. A lower groove is formed in the lower portion of the outer surface of the ball body, a plurality of right communicating grooves are formed in the right portion of the inner cavity wall of the ball body, a plurality of left communicating grooves are formed in the left portion of the inner cavity wall of the ball body, an inner circular groove is formed in the middle of the inner cavity wall of the ball body, and the inner groove wall of the inner circular groove is coated with a second abrasion-resistant layer. According to the ceramic ball with the grooves and the holes, the upper grooves and the lower grooves are formed in the whole ceramic ball with the holes, and the inner circular grooves are formed in the ceramic ball with the holes, so that the ceramic ball with the holes can be used as a cushion material for supporting and covering a catalyst and can be used as tower packing.
