Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of vertical mill grinding disc application, specifically a vertical mill grinding disc cleaning device. Background Technology
[0002] Vertical roller mills are widely used in the cement, metallurgy, and mining industries for grinding materials. During long-term operation, materials (such as slag and cement raw materials) easily adhere to the grinding discs, forming a hardened layer. If this material is not cleaned promptly, it will cause unevenness on the grinding disc's working surface, reducing grinding efficiency, increasing energy consumption, and even affecting the equipment's lifespan.
[0003] Currently, common cleaning methods include manual cleaning and mechanical scraper cleaning. Manual cleaning is inefficient, labor-intensive, and poses safety hazards; while traditional mechanical scrapers are mostly rigid structures, which can easily damage the grinding disc surface due to excessive pressure during the cleaning process, or result in incomplete cleaning due to uneven material thickness. In addition, some cleaning devices only use a single scraping method, resulting in limited cleaning effectiveness. Therefore, there is an urgent need for a vertical mill grinding disc material cleaning device to solve the above technical problems. Utility Model Content
[0004] To address the above problems, this utility model provides a vertical mill grinding disc cleaning device to solve the technical problems of low efficiency and damage to the grinding disc in the existing vertical mill grinding disc cleaning process.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A vertical mill grinding disc cleaning device is installed inside the grinding disc. A support frame is installed inside the grinding disc, and a fixed plate is installed on one side of the support frame. An electric push rod is installed on the fixed plate. The telescopic end of the electric push rod is connected to a movable block. The side end of the movable block is connected to a scraper through a spring assembly. A brush body is installed at the lower end of the movable block, and the upper end of the movable block is mounted on a guide rail through a slider. The spring assembly includes a first connecting block installed at the side end of the movable block, a second connecting block installed at the side end of the first connecting block, and a spring installed on the second connecting block. The other side of the spring is installed inside a fixed block, which is located at the side end of the scraper.
[0007] As a further improvement to the above solution, the first connecting block and the second connecting block are connected by bolts.
[0008] As a further improvement to the above solution, the fixing block is set to a U-shape.
[0009] As a further improvement to the above solution, limit plates are provided on both sides of the guide rail.
[0010] As a further improvement to the above solution, the fixing plate is set to L-shape, and the fixing plate is connected to the support frame by bolts.
[0011] As a further improvement to the above solution, the brush body is mounted on the movable block via a mounting block.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] This invention provides a vertical mill grinding disc cleaning device. An electric push rod drives a movable block, simultaneously moving the scraper and brush body to achieve dual cleaning of scraped material and brushed residue, improving cleaning efficiency. The spring assembly design allows the scraper to elastically adjust pressure when in contact with the grinding disc, avoiding rigid contact that could damage the disc surface, while ensuring adaptability to different thicknesses of adhesive material.
