Description

Wear-resisting roll surface wear online homogenizing mechanism

Technical Field

The utility model relates to a cement processing technology field, concretely relates to online homogenization mechanism of wear-resisting roll surface wearing and tearing.

Background

The roller press, also known as a high-pressure roller mill, is a novel energy-saving cement grinding device developed in the middle of the 80 s of the 20 th century, is widely applied to superfine grinding operation in the fields of metallurgical mines, chemical industry, building material cement and the like, and has the advantages of high efficiency, energy conservation, environmental protection and the like. The roller press generally comprises 2 rollers, and the material is fed from the middle of the two rollers, and pressure is applied to the material through the relative rotation of the two rollers. The crushed material is extruded to form a compact material bed, and enters the next procedure from the lower parts of the two rollers. After a period of normal operation, the stud roll surface has wearing and tearing of different degrees, and edge effect will lead to roll surface width middle part wearing and tearing big, edge wearing and tearing little for two rollers are at the ascending interval of width direction inconsistent, can lead to the material of middle part to directly get into next process through not extrudeing when serious. Therefore, when the wear-resistant roller surface still has a long service life, the working efficiency of the roller mill is reduced sharply.

In the prior art, two methods of off-line repair and on-line repair are generally adopted to carry out grinding repair on a roller surface, wherein the off-line repair refers to that when a roller press is stopped, a grinding wheel is driven by a grinder to rotate so as to carry out off-line grinding on the roller surface; in the on-line repair, a fixed grinding wheel is used to grind the edge roll surface when the roller press is in normal operation.

For the on-line repairing scheme, patent CN 204487299U discloses a roller surface wear homogenizing mechanism of a high-pressure roller mill, which is installed inside a frame, and a grinding wheel is pre-tightened by a screw and a disc spring, and the roller surface is ground and homogenized by the rotation of the roller when the roller mill normally operates. However, the following technical problems still exist: 1. because the roll squeezer has large dust in the operation process, the interior of the whole roll squeezer is in a sealed state, the roll surface has high wear resistance, a large amount of grinding wheels are consumed, and the grinding wheel loss state is difficult to observe by a homogenizing mechanism arranged on the inner side of a frame; 2. the patent needs to enter the interior of the roller press to replace the grinding wheel, but the roller press has compact structure, internal sealing and narrow space, and the grinding wheel fixed by the bolt is difficult to replace; 3. the abrasion height at the edge of the roller surface of the roller press is gradually changed, the width of the roller surface is generally 1000mm to 2000mm, the whole roller width is frequently required to be homogenized, and the device is inconvenient to move to carry out homogenization; 4. because the grinding wheel is fixed by the bolts, the grinding wheel needs to be replaced when still having more service life, and waste is caused.
