Description

TECHNICAL FIELD

[0001] The utility model relates to a liner measuring tool for a millstone of a vertical mill. BACKGROUND

[0002] A vertical mill is an ideal large-scale grinding equipment, and is a large-scale core equipment in the process industry of cement, electric power, metallurgy, chemical industry, non-metallic mineral and the like, and its running state directly affects the production safety and economic benefits of an enterprise. Therefore, each enterprise highly values the daily maintenance and repair quality thereof.

[0003] The vertical mill adopts a material layer grinding principle to grind materials, and has low energy consumption, and the power consumption of a grinding system is 20%-30% lower than that of a ball mill. However, the average proportion of the wear loss to the original weight of a part is only 5%-20%. In the use process of a mill roller body and a wear-resistant liner plate, once a fit clearance occurs, the wear between the body and the liner plate will be aggravated, and in addition, the fit surface is continuously washed by hot air and cement particles, which results in the occurrence of wear grooves in the mill roller and the millstone liner plate, and will seriously affect the use effect. If the wear is serious, the mill roller and the millstone liner plate must be replaced, and the replaced parts are directly scrapped, which will cause huge economic losses to the enterprise. The repair of the millstone liner plate is one of the indispensable parts of the daily maintenance of the vertical mill, and the repair quality plays a decisive role in the stable operation of the whole unit.

[0004] Since most of the produced vertical mill units are not equipped with special measuring tools for the millstone liner plate, the measuring methods adopted by the repair personnel are mostly not in conformity with the requirements, and the most primitive method is generally adopted in the measuring process: a card plate is used to measure the curvature of the millstone liner plate, and the clearance between the card plate and the millstone liner plate is measured by a tape measure. If it is unqualified, the vertical mill liner plate is continuously built up on the arc surface and the above steps are repeated until the clearance between the card plate and the millstone liner plate reaches the specified value. The whole measuring process usually needs to be completed by multiple people, and is not only low in efficiency and high in labor intensity, but also difficult to guarantee the repair precision. In addition, since the inner circle and the outer circle of the millstone liner plate are different in height, the card plate has no fulcrum, the level meter will lose support, and will fall on the millstone liner plate if not careful, which will easily damage the level meter and the arc surface of the millstone liner plate, and will result in the necessity of re-building and repairing. Since the repair time of the millstone liner plate is relatively long, the start-up time of the equipment is delayed, and the production is affected.

[0005] Therefore, the vertical mill millstone liner plate measuring tool is proposed to solve the above-mentioned problems. CONTENT OF THE UTILITY MODEL
