Double-slide-shoe-bearing tube mill cylinder with effective insulating discharge end

Abstract

The invention discloses a double-slide-shoe-bearing tube mill cylinder with an effective insulating discharge end. The double-slide-shoe-bearing tube mill cylinder with the effective insulating discharge end comprises a cylindrical cylinder, a feed end slide ring welded to the feed end of the cylindrical cylinder, and a discharge end slide ring sleeved to the outer side of the outlet end of the cylindrical cylinder. The discharge end slide ring comprises a cylinder connecting part, a heat conducting cavity and an insulating connecting part sequentially arranged from the cylindrical cylinder to an outlet direction; a first insulating protruded ring is arranged at the inner wall of the cylinder connecting part; a second insulating protruded ring is arranged in the insulating connecting part; and correspondingly, a first insulating gasket is lap-jointed at a position, located on the first insulating protruded ring, of the cylinder connecting part, in a direction towards the cylindrical cylinder, and a second insulating gasket is arranged at the outer side, located on the second insulating protruded ring, of the insulating connecting part. According to the double-slide-shoe-bearing tube mill cylinder provided by the invention, the discharge end slide ring is insulated through the first insulating gasket, the second insulating gasket, the first insulating protruded ring and the second insulating protrude ring arranged sequentially, so that the temperature of the double-slide-shoe-bearing tube mill cylinder during a working process is reduced.

Description

technical field [0001] The invention relates to the technical field of a tube mill with double sliding shoe bearings, in particular to a cylinder body of a tube mill with double sliding shoe bearings and high-efficiency heat insulation at the discharge end. Background technique [0002] At present, compared with the hollow shaft tube mill, the double sliding shoe tube mill has the following advantages: [0003] 1. Since the sliding shoe bearing cancels the hollow shaft and the main bearing, the rotating part of the whole mill is shortened a lot. [0004] 2. The distance between the supporting points at both ends of the mill is shortened, so the bending stress of the mill barrel is reduced, which improves the force condition of the barrel and thus improves the safety factor of the mill. Therefore, the mill shell can be made of thinner steel plate. In addition to saving manufacturing costs, grinding bodies can also be added to increase the output of finished products. [00...

AI Technical Summary

Problems solved by technology

In the prior art double-shoe bearing tube mill, the slip ring at the discharge end and the cylinder are directly welded together. Therefore, a large amount of heat inside the cylinder will be transferred to the sliding shoe bearing pad through the cylinder slip ring. As a result, the temperature of Towa is as high as 75 degrees or more

The lining tile of the sliding shoe bearing pad is Babbitt alloy, and the working temperature of Babbitt alloy is relatively low. When the temperature of the paddle reaches a certain temperature, the Babbitt alloy will be melted, which is commonly referred to as paddle burning. Bad

This can render the entire mill inoperable, causing serious economic losses
