A semi-shaft type magnetic separator drum with compression type end cover installation

Abstract

The invention provides a semi-shaft type magnetic separator drum with a compact end cover. The drum comprises a drum body, the end cover, a main shaft, a bearing, an inner gland cover, an outer gland cover, a magnetic system and the like, wherein a flange and the end cover which are arranged at two ends of the body are connected by bolts; the end cover is tightly clamped by the inner gland cover and the outer gland cover; the bearing is arranged in an inner cavity formed by the inner gland cover and the outer gland cover; the bearing is a tapered bore bearing, and the bearing and the main shaft are connected by a taper sleeve; the main shaft is of a plain shaft structure, and has no pillow block; all parts are sealed by O-shaped rings. The semi-shaft type magnetic separator drum based on the structure has a simple structure, and can be made of stainless steel plates without needing casting process; the bearing and the main shaft are conveniently dismounted and mounted without using special tools; the main shaft is designed into the plain shaft, the processing cost is low, and the mounting of the parts is simple.

Description

technical field [0001] The invention belongs to the technical field of magnetic separator parts, and in particular relates to a half-shaft magnetic separator drum installed with a compression type end cover. Background technique [0002] Magnetic separator is a kind of iron ore beneficiation equipment, the working principle is to use the magnetic field of the magnetic system and the operation of the drum to separate the useful minerals in the pulp. The drum is one of the main components of the magnetic separator. It is usually composed of a cylinder, an end cover, a main shaft and a bearing, and its inner cavity is used to install the magnetic system. The cylinder is connected to the main shaft through the end cover, bearing and other parts at the side end, and rotates around the fixed main shaft under the drive of the external drive. The end cover of the drum mainly plays the role of supporting the cylinder and transmitting torque, and the bearing is installed in the inner...

AI Technical Summary

Problems solved by technology

The drum is immersed in water, so the sealing requirements are very high when the drum is assembled. Rubber pads or asbestos pads are often used to seal the parts on the drum. Often due to poor sealing, the pulp or water vapor enters the drum and corrodes the internal parts. The magnetic block and parts will also have poor assembly accuracy due to the size of the gasket, and the rotation of the drum is prone to failure
