Flotation machine with integrated bolts and cover board

Abstract

The invention discloses a flotation machine with integrated bolts and cover board. The flotation machine comprises a trough body, a bearing body, an air cylinder, a main shaft, a cover board, tapered square-head bolts and an impeller, wherein three cast iron brackets are arranged on the back part of a hollow disk; tapered square holes are formed in the cast iron brackets; the sizes of the tapered square holes are matched with those of the tapered square heads; the positions of the tapered square holes correspond to those of ear holes in the air cylinder; the tapered square heads of the tapered square-head bolts are arranged in the tapered square holes of the cast iron brackets and are locked through lock nuts; and a polyurethane layer is sprayed on the surface of each cast iron bracket, so that the tapered square heads are buried into the polyurethane layers. The tapered square heads of the tapered square-head bolts are buried into polyurethane; the tapered square heads do not directly contact ore pulp when working and are not easily abraded; and the cover board is not easy to fall off, so that the flotation machine has the advantages of abrasive resistance and long service life.

Description

technical field [0001] The invention relates to mine metallurgical equipment, especially a flotation machine. Background technique [0002] The mechanical stirring flotation machine is mainly used for sorting non-ferrous metals such as lead, zinc, copper, nickel, gold, etc., and can also be used for rough selection and selection of ferrous metals and non-metals. The flotation machine is composed of motor, tank body, bearing body, air cylinder, main shaft, impeller, cover plate and so on. The tank body is a container for containing ore pulp. The bearing body is installed above the tank body with angle steel. The upper end of the air cylinder is connected to the bearing body through a flange, and the lower end has three ears with holes connected to the cover plate. The main shaft is installed in the bearing body. The first bearing is fixed, the lower end of the main shaft is equipped with an impeller, the distance between the impeller and the cover plate is 5-8 mm, the impell...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to solve the problems in the prior art that the conical lag bolts of the cover plate wear fast, and the service life of the conical lag bolts and the cover plate does not match, which causes the pulp to easily produce eddy currents and the cover plate is easy to drop. , providing an integrated flotation machine with tapered lag bolts that are wear-resistant and have a long service life.
