Abstract

The invention discloses an impeller cover plate connecting structure for a GF type flotation machine and a transformation and installation method of the impeller cover plate connecting structure, belongs to the field of GF type flotation machine equipment, and can remarkably reduce abrasion of ore pulp to a connecting piece of an impeller cover plate and prolong the service life of the equipment. The impeller cover plate connecting structure for the GF type flotation machine comprises a machine body assembly and an impeller cover plate, the impeller cover plate is installed on the machine body assembly through a connecting piece, a threaded blind hole is formed in the impeller cover plate, and the connecting piece is connected with the threaded blind hole in the impeller cover plate so that the impeller cover plate can be installed on the machine body assembly. According to the invention, the threaded blind hole is formed to replace traditional bolt through holes, meanwhile, the connecting piece which does not penetrate through the impeller cover plate is adopted for connection, and therefore the connecting piece can be prevented from penetrating through the impeller cover plate, the situation that the connecting piece of the impeller cover plate is abraded and damaged by ore pulp can be effectively reduced, and the overall service life of equipment can be prolonged.

Description

technical field [0001] The invention relates to the field of GF-type flotation machine equipment, in particular to a connection structure of an impeller cover plate for a GF-type flotation machine and a modification and installation method thereof. Background technique [0002] GF type flotation machine is a device used for flotation of materials. The impeller cover plate of GF type flotation machine is now fixed on the flotation machine assembly with conical bolts. After merging with the inhaled gas, it leaves the impeller blades with a large tangential and radial momentum, and evenly disperses into the flotation tank. The installation structure of the original impeller cover plate has the following defects: the tail of the tapered bolt is directly exposed after passing through the bolt through hole on the impeller cover plate and is in contact with the slurry. Cause the impeller cover plate to fall off, causing production shutdown. Contents of the invention [0003] Th...
