Description

Technical Field

[0001] The utility model relates to the technical field of scrapers for coal vertical mills in cement production, and specifically relates to a scraper device for a coal vertical mill in cement production. Background Technique

[0002] Cement is a powdery inorganic gel material. Various equipment will be used in the production process of cement. The coal vertical mill is one of them. When the coal vertical mill is in use, a scraper device for a coal vertical mill in cement production is required.

[0003] According to a scraper device for a coal vertical mill in cement production (authorization announcement number: CN217940347U) disclosed on the patent network, it is described that "the utility model discloses a scraper device for a coal vertical mill in cement production, including a grinding disc. Installation blocks are evenly installed at the bottom end of the outer side wall of the grinding disc. One end of each installation block is installed with a scraper main body. Installation holes are arranged at the top end inside the scraper main body, and first bolts are installed inside the installation holes. First reinforcing ribs are arranged inside the reinforcing strips, and second reinforcing ribs are arranged inside the first reinforcing ribs. Through the setting of an anti-deformation structure, the anti-deformation structure is arranged inside the scraper main body, and the reinforcing strips, first reinforcing ribs and second reinforcing ribs included therein form a welded integration, enhancing the overall structural strength of the scraper main body, making the scraper main body not easily deformed or bent and damaged as the scraping working time increases, making the use effect of the scraper main body better, and effectively extending the service life of the scraper main body."

[0029] The replacement mechanism 3 includes an installation component 31 and an automatic adjustment component 32, and the automatic adjustment component 32 is arranged inside the installation component 31.

[0030] Furthermore, the installation component 31 includes four fixed shafts 311, all four fixed shafts 311 are fixedly installed inside the installation block 2, a fixed block 312 is fixedly installed outside the fixed shaft 311, a movable groove 313 is opened inside the fixed shaft 311, a spring A 314 is fixedly installed inside the fixed shaft 311, one end of the spring A 314 away from the fixed shaft 311 is fixedly installed with a movable column 315, a movable block 316 is fixedly installed outside the movable column 315, one end of the movable column 315 away from the spring A 314 is fixedly installed with a baffle 317, and a control block 318 is fixedly installed on one side of the baffle 317 away from the movable column 315 to control the movement of the baffle 317.

[0031] Furthermore, the movable block 316 is movably installed inside the movable groove 313, and the movable column 315 is movably installed inside the fixed shaft 311 to drive the movement of the baffle 317.

[0032] Further, the automatic adjustment component 32 includes four insertion blocks 321 which are respectively arranged inside the four fixed blocks 312. A rectangular block 322 is fixedly installed at the bottom of the insertion block 321. Two spring Bs 323 are fixedly installed inside the rectangular block 322. One end of the two spring Bs 323 away from the rectangular block 322 is fixedly installed with a slider 324. Two anti - detachment blocks 325 are fixedly installed on the outer part of the slider 324 to prevent the slider 324 from completely detaching from the inside of the rectangular block 322.

[0033] Further, the anti - detachment block 325 is slidably installed inside the rectangular block 322, the slider 324 is slidably installed inside the rectangular block 322, and the baffle 317 contacts the insertion block 321, enabling the installation of the insertion block 321.

[0034] Embodiment Two:

[0035] Please refer to Figure 5 , and in combination with Embodiment One, it is further obtained that the protection mechanism 4 includes four scraping plates 41 which are respectively fixedly installed at the bottoms of the four sliders 324. Two threaded holes 42 are opened in each of the four scraping plates 41. A limiting post 43 is fixedly installed inside the scraping plate 41. A reinforcing edge 44 is arranged outside the scraping plate 41. An installation groove 45 is opened inside the reinforcing edge 44. Two bolts 46 are threadedly installed inside the reinforcing edge 44 for installing the reinforcing edge 44.

[0036] Further, the bolt 46 is threadedly installed inside the threaded hole 42, the limiting post 43 is movably installed inside the installation groove 45, and the top of the reinforcement edge 44 contacts the slider 324, making the installation closer.
