Vertical mill roll sleeve

Abstract

The invention belongs to the technical field of roll sleeves, and specifically discloses a vertical mill roll sleeve. The vertical mill roll sleeve comprises a roll sleeve main body, an arc-shaped plate, a semi-ring rubber ring, a bolt, a nut, a slide groove, a magnetic ring I, a spring I, a press rod, a circular groove, a spring II, a press sheet, an oil spray pipe, an oil spray hole, a connection pipe, a magnetic ring II, a magnetic block and a ring groove. According to the vertical mill roll sleeve, the bolt is unscrewed, the bolt rotates so that the nut moves along the bolt, the nut movesto drive the arc-shaped plate to move, the arc-shaped plate moves to drive the press sheet to move and then extrudes the semi-ring rubber ring, the semi-ring rubber ring carries out reverse extrusionon the press sheet, so that the spring II generates elasticity, and the semi-ring rubber ring is facilitated to cling to a mill roll due to the elasticity of the spring II, so that the probability ofthe entrance of dust into the roll sleeve main body is lowered; and the connection pipe is connected with an oil conveying pipe, then an oil pot is extruded, oil in the oil pot enters the oil spray pipe through the oil conveying pipe and the connection pipe, the oil flows onto the inner wall of the roll sleeve main body through the oil spray hole, and fixing for one end of the connection pipe intoa groove can be facilitated through the magnetic ring I and the magnetic block.

Description

technical field [0001] The invention belongs to the technical field of roller sleeves, in particular to a vertical mill roller sleeve. Background technique [0002] As a main grinding equipment, the vertical mill is widely used in grinding raw materials, cement, coal powder and other occasions. The vertical mill has stable mechanism performance, high abrasive efficiency and long service life. At present, most domestic vertical mill roller sleeves are in the form of conical surface tension. There is no or only one key inside the roller sleeve, and the grinding roller is connected to the main body of the roller sleeve through interference fit. [0003] There are certain defects in the currently used roller sleeves of vertical mills. The lack of sealing mechanism causes rainwater or other impurities to enter the main body of the roller sleeve through the gap between the grinding roller and the main body of the roller sleeve, causing damage to the grinding roller. At the same t...

Problems solved by technology

[0003] There are certain defects in the currently used roller sleeves of vertical mills. The lack of sealing mechanism causes rainwater or other impurities to enter the main body of the roller sleeve through the gap between the grinding roller and the main body of the roller sleeve, causing damage to the grinding roller. At the same time, it lacks a convenient lubrication mechanism. It is inconvenient to apply oil to the inside of the sleeve body, and it is inconvenient to press the grinding roller into or out of the inside of the sleeve body
