AI Technical Summary

Problems solved by technology

In this structure, the weight of the magnetic system on the driving end side of the main shaft is all supported by the bearing, and the load of the bearing is very large. Therefore, the service life of the general bearing is not high. Once the bearing is damaged, the magnetic system will fall, causing the magnetic system and the cylinder to scratch. Touch, easy to scratch the magnetic system or cylinder

Embodiment Construction

[0007] As shown in the figure, the present invention includes a cylinder body 2 , an end cover 3 , a main shaft 1 , a magnetic system 8 and a bearing 6 . The main shaft 1 runs through the barrel 2, and its main and driven ends 9, 10 pass through the bearing 6 respectively and are supported on the shaft seat 7 fixed on the frame. The bearing 6 is positioned through the bearing gland 5. The bearing seat 5 on one side of the driven end 10 is connected to the end cover 3 on the inner side by bolts 11 . The bearing cover 5 on one side of the driving end 9 is respectively connected to the end cover 3 and the gear 4 on both sides by bolts 11 . In this way, the driving device can drive the cylindrical body to rotate around the main shaft 1 through the gear 4 . The magnetic system 8 is fixed on the main shaft 1 in the cylinder body 2, placed inside the cylinder body 2, and is a fixed non-rotating part.

Abstract

The invention discloses a through-shaft rotary drum of magnetic separator, comprising a drum body, and end cover, a main shaft, a magnetic system and bearings. The main shaft passes through the drum body, two ends of the main shaft support the drum body trough the bearings, and thus, the drum body can rotate around the main shaft; the driven end of the main shaft passes through the bearing and supports a shaft seat; and the driving end of the main shaft also penetrates through the bearing and supports the shaft seat. By the structure, since the driving end of the main shaft also penetrates through the bearing and supports the shaft seat, namely, the main shaft is of a through-shaft structure of which two ends both support the shaft seat at outside of the rotary drum, and the weight of the magnetic system can be directly transferred to the shaft seat at outside of the rotary drum through the main shaft. The bearings only support weight of the drum body, stress on the bearings is reduced greatly, and the service life is prolonged greatly. Moreover, when the bearings are broken, the magnetic system cannot fall down and scrape or strike the drum body, the equipment reliability is improved greatly, and the workload of maintenance for workers is reduced.

Description

technical field [0001] The invention belongs to the technical field of magnetic separator components, and in particular relates to a through-shaft magnetic separator drum. 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 parts of the magnetic separator, usually composed of cylinder body, end cover, main shaft, magnetic system, bearing and other parts. The main shaft runs through the barrel, the driven end passes through the bearing and is supported on the shaft seat, and the driving end is supported on the bearing. The magnetic system is fixed on the main shaft in the cylinder and placed inside the cylinder, which is a fixed non-rotating part. The barrel is a rotating part, which is connected with the driving device through the end cover. The magnetic ...
