Abstract

The utility model relates to a grind the mill immediately, specifically a grind mill abrasionproof structure immediately. Including disk body and welt, the disk body is installed in the mill, is supported by the speed reducer, is connected with the flange of speed reducer through the bolt, and the upper portion working face of disk body sets up the welt, and the welt compresses tightly on the disk body through the wedge briquetting, and welt surfacing has the wearing material layer, and disk body and welt outer peripheral edge seam department open have the through-hole that top-down link up wearing material layer, welt and disk body, and the through-hole is evenly arranged along the welt circumference. The utility model discloses with the help of the rotatory centrifugal action that produces the material of mill, iron fillings are got rid of to welt periphery in-process, utilize the dead weight of iron fillings to pass through the perforating hole and fall down, avoid or reduced the wearing and tearing of iron fillings to the mill, improved the life of mill.

Description

Wear-resistant structure of grinding disc of vertical mill

Technical Field

The utility model relates to a grind the mill immediately, specifically a grind mill abrasionproof structure immediately.

Background

The millstone is a main part of the vertical mill, materials (slag) fall to the center of the millstone through two air locking valves and a blanking pipe, the millstone rotating at a constant speed uniformly disperses and flattens the materials outwards under the action of centrifugal force to form a material bed with certain thickness, the materials are rolled by a plurality of grinding rollers on the millstone in the process and are crushed under the action of a pressure roller, and the iron filings exist in the materials, so that the iron filings and the millstone can generate serious friction in the grinding process, and the service life of the millstone is shortened.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem to provide a can reduce iron fillings and the friction of mill, improve mill life's vertical mill abrasionproof structure.

The utility model provides a problem, the technical scheme who adopts is:

the utility model provides a vertical mill disc abrasionproof decreases structure, includes disk body and welt, and the disk body is installed in the mill, is supported by the speed reducer, is connected with the flange of speed reducer through the bolt, and the upper portion working face of disk body sets up the welt, and the welt compresses tightly on the disk body through the wedge briquetting, and welt surfacing has the wearing layer, and disk body and welt outer peripheral edge seam department open have the through-hole that top-down link up wearing layer, welt and disk body, and the through-hole is evenly arranged along the welt circumference.

Adopt above-mentioned technical scheme the utility model discloses, compare with prior art, its outstanding characteristics are:

with the help of the centrifugal action of the grinding disc rotation on the material, the scrap iron is thrown to the periphery of the lining plate and falls down through the through hole by utilizing the dead weight of the scrap iron, so that the abrasion of the scrap iron on the grinding disc is avoided or reduced, and the service life of the grinding disc is prolonged.

Preferably, the present invention further provides:

the through hole is a conical through hole with a small upper hole diameter and a large lower hole diameter, and the structure is more beneficial to discharging scrap iron.

Drawings

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

in the figure: a tray body 1; pressing the blocks 2; a lining plate 3; a wear-resistant material 4; a through hole 5.

The specific implementation mode is as follows:

the invention will be further described with reference to the following examples, which are intended only for better understanding of the invention and therefore do not limit the scope of the invention.

Referring to fig. 1, an anti-abrasion structure of a vertical grinding disc comprises a disc body 1, a wedge-shaped pressing block 2 and a lining plate 3, wherein the disc body 1 is installed in a grinding machine and supported by a speed reducer and connected with a flange of the speed reducer through a bolt, the lining plate 3 is arranged on the working surface of the upper part of the disc body 1, the lining plate 3 is tightly pressed on the disc body 1 through the wedge-shaped pressing block 2, a wear-resistant material layer 4 is welded on the surface of the lining plate 3 in a stacking mode, materials are ground on the wear-resistant material layer 4, and the wear-resistant material layer 4 can be subjected to repair welding after being worn; the disk body 1 and 3 outer peripheral edge seams of welt department open and have top-down to link up wearing material layer 4, the perforating hole 5 of welt 3 and disk body 1, perforating hole 5 evenly arranges along 3 circumference of welt, and the big conical through-hole that is big end down in the aperture, iron fillings in the material are got rid of to 3 periphery in-process of welt with the help of the rotatory centrifugal action that produces the material of mill, lean on its dead weight can fall into perforating hole 5 and outside the discharge mill, avoid or reduce the wearing and tearing of iron fillings to the mill.

The utility model discloses with the help of the rotatory centrifugal action that produces the material of mill, iron fillings are got rid of to 3 periphery in-processes of welt, utilize the dead weight of iron fillings to pass through perforating hole 5 and fall down, avoid or reduced the wearing and tearing of iron fillings to the mill, improved the life of mill.

The above description is only a preferred and practical embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent variations made by using the contents of the specification and the drawings are included in the scope of the present invention.

Claims

1. The utility model provides a vertical mill abrasionproof decreases structure, includes disk body and welt, and the disk body is installed in the mill, is supported by the speed reducer, is connected through the flange of bolt with the speed reducer, and the upper portion working face of disk body sets up the welt, and the welt compresses tightly on the disk body through the wedge briquetting, and the welt surface surfacing has the wearing material layer, its characterized in that: the joint of the disc body and the outer periphery of the lining plate is provided with through holes which penetrate through the wear-resistant material layer, the lining plate and the disc body from top to bottom, and the through holes are uniformly distributed along the circumference of the lining plate; the through hole is a conical through hole with a small upper hole diameter and a big lower hole diameter.
