[0004] At present, the scraper device 105 of the vertical mill is fixed on the shell of the mill through a spiral structure. When there are coarse materials or unbreakable large miscellaneous iron encountering the scraper, the scraper cannot avoid it and will cause huge damage. impact and damage, and the current scraper is inconvenient to compensate and adjust after wear
After the scraper or the scraper device is broken, it will cause great damage to the grinding roller and the entire operating system

Abstract
The invention discloses a scraping plate protection mechanism of a vertical mill. The scraping plate protection mechanism of the vertical mill is used for protecting a scraping plate device of the vertical mill. A through hole through which the scraping plate device stretches into a mill shell is formed in the mill shell of the vertical mill; and a cover plate which covers the through hole is arranged at the outer end of the through hole. The scraping plate protection mechanism of the vertical mill comprises an elastic buffering device which is arranged on the cover plate, wherein an installation rod of the scraping plate device is connected with the elastic buffering device; and the installation rod is hinged on a supporting seat. The scraping plate protection mechanism provided by the invention has the advantages that: when too-large particles or large pig irons occur in the operation process of a scraping plate, the scraping plate can be impacted and forced to move to the inside ofa milling cylinder along the inner wall of the milling cylinder, the installation rod of the scraping plate device pulls the elastic buffering device, the elastic buffering device is forced to be compressed under the action of a pulling force, and a clearance between the scraping plate and a milling surface of the milling cylinder is correspondingly enlarged, so that the scraping plate can be protected after crossing obstacles, and the elastic buffering device returns to an initial state after the scraping plate crosses the obstacles.
Description
technical field [0001] The invention relates to the technical field of vertical mills, in particular to a scraper protection mechanism for vertical mills. Background technique [0002] The vertical mill is suitable for grinding and crushing various materials. The materials produced by the vertical mill have uniform particle size and fine particles. The vertical ball mill can also mix several kinds of materials very uniformly. It is widely used in cement, chemical industry Raw materials, abrasives, ceramics, ores, coal powder, metal powder, magnetic materials, etc. Due to the unique grinding performance of the vertical mill, it has been widely used in the industry. [0003] Such as figure 1 As shown, the current vertical mill comprises a housing 102, a driving device 101, a vertical grinding cylinder 103 driven by the driving device 101, a grinding roller 106, and a pressurizing device 108 acting on the grinding roller 106. 108 is provided with pressure by oil cylinder 109...
