Description

TECHNICAL FIELD

[0001] The utility model relates to a roll press device accessory in the field of cement production equipment, in particular to a roll press feeding device roll sleeve two end face side baffle. BACKGROUND

[0002] The side baffle is a device for ensuring that the material passes through the feeding pipe and goes through the roll face, and the material is discharged from the roll gap after being extruded by the roll face. Since the roll sleeve end face and the side baffle are matched with a gap, part of the material enters the gap between the roll sleeve two end faces and the side baffle in the extrusion process, which causes the roll sleeve two end faces to be severely worn or to have edge collapse in a short time, reduces the service life of the roll sleeve, and causes material leakage and unstable internal material pressure, which affects the grinding effect. SUMMARY

[0003] The utility model discloses a roll press feeding device roll sleeve two end face side baffle, solves the situation that the roll sleeve two end faces are easily worn or have edge collapse to cause material leakage, keeps the internal material pressure of the roll press stable, and produces better grinding effect, and can prolong the service life of the wear-resistant layer of the roll sleeve.

[0004] The utility model discloses a roll press feeding device roll sleeve two end face side baffle, solves the situation that the roll sleeve two end faces are easily worn or have edge collapse to cause material leakage, keeps the internal material pressure of the roll press stable, and produces better grinding effect, and can prolong the service life of the wear-resistant layer of the roll sleeve.

[0005] A roll press feeding device roll sleeve two end face side baffle, characterized in that: including end face sealing baffle, lower part radial sealing herringbone wear -resistant board and upper part radial sealing wear -resistant board, end face sealing baffle for axial roll end face sealing is set up in roll sleeve two end faces, and is fixed on the frame, and lower part radial sealing herringbone wear -resistant board and upper part radial sealing wear -resistant board are fixed on end face sealing baffle, and are close to inverted herringbone, are formed by the straight edge of upper part and the two arc edges of side, and the arc edge cooperates with the roll face, and forms the radial sealing to the roll face.

[0006] Further, the end face sealing baffle is arranged on the outer side of the roll width.

[0007] The lower part radial sealing herringbone wear-resistant plate and the upper part radial sealing wear-resistant plate are located on the inner side of the roll width of the two side edges of the roll width, and the side edges of the two rollers are in arc shape matched with the roll face.

[0008] The utility model discloses, the roller sleeve two end faces set end face sealing baffle, roller sleeve two end faces set lower part radial seal herringbone wear plate and upper part radial seal wear plate, end face sealing baffle is used for the baffle of axial roller end face sealing, this baffle is between the roller between certain distance, lower part radial seal herringbone wear plate and upper part radial seal wear plate are in the roller width both sides edge roller width, its opposite two rollers'side edge is with the roller face matching's circular arc, and is spaced apart with the roller face, its two side edges form the radial seal of opposite roller face with the roller face matching, the material that is discharged from the crushing cavity is blocked by the herringbone wear plate of this device, is difficult to reach the roller edge, to solve the wear or the collapse edge of roller sleeve two end faces easily produces the leakage condition, makes the material pressure of roller press internal keep stable, produces better grinding effect, and can prolong the service life of roller sleeve wear layer.

[0009] The utility model discloses the beneficial effect:

[0010] Solve the wear or the collapse edge of roller sleeve two end faces easily produces the leakage condition, make the material pressure of roller press internal keep stable, produce better grinding effect, and can prolong the service life of roller sleeve wear layer. DRAWINGS
