Centrifugal machine screen basket with screen net capable of being replaced conveniently

Abstract

The invention discloses a centrifugal machine screen basket with a screen net capable of being replaced conveniently. The centrifugal machine screen basket comprises a first lower flange, a first upper flange is arranged on the first lower flange, a plurality of first reinforcing ribs are fixedly arranged between the first lower flange and the first upper flange, the number of the first reinforcing ribs is eight, and grooves are formed in the inner walls of the first reinforcing ribs; a lifting device is arranged on the first lower flange, the lifting device comprises a tray, and four cavity channels are arranged in the tray; and sliding rods are arranged in the cavity channels, limiting sliding blocks are fixedly arranged at one ends of the sliding rods, one ends, far away from the limiting sliding blocks, of the sliding rods extend out of the cavity channels, threaded holes are formed in one ends, away from the limiting sliding blocks, of the sliding rods, and threaded rods are arranged in the threaded holes. The centrifugal machine screen basket with the screen net capable of being replaced conveniently has the beneficial effects that the replacement of the large screen net is greatly facilitated, the labor force for replacing the screen net is liberated, moreover, the replacement process is stable, and the screen net cannot collide with the screen basket.

Description

technical field [0001] The invention relates to the field of coal mine machinery, in particular to a centrifuge screen basket which is convenient for replacing the screen mesh. Background technique [0002] The screen basket is mainly composed of an upper flange, a lower flange, a reinforcing rib, a reinforcing ring, and a stainless steel conical mesh cylinder. The mold is independently designed and outsourced), the fan-shaped screen is rolled by stainless steel wire into a special shape of the screen bar and the support bar is welded and formed by special equipment, and the screen bar is arranged along the conical generatrix of the screen basket. [0003] The role of the centrifuge in the coal preparation plant is to dehydrate clean coal and medium coal. It mainly relies on the high-speed operation of the screen basket to achieve dehydration. The screen is large in size and heavy in weight. According to the patent CN201720893180.X, a centrifuge is disclosed Although the ...
