Description

Technical Field

[0001] The utility model belongs to the technical field of flotation machines, and in particular relates to a flotation machine scraper cleaning device. Background Art

[0002] When scrapers of flotation machines scrape up foam attached to mineral particles, they scrape and contact repeatedly. A small amount of pulp and mineral particles are likely to adhere to the surface of the scrapers, affecting the scraping and sorting effect of the mineral particle foam. Current flotation machines generally do not have a special cleaning device for the scrapers. Generally, the scrapers are disassembled, replaced or cleaned only after the mineral material sorting is completed. However, during the sorting process, the scrapers are not cleaned in time, and the mineral particle foam scraped up by the scrapers is not quickly cleaned away. A small amount of mineral particle foam is transferred back to the pulp surface with the scrapers, which will affect the effect of scraping up the mineral particle foam next time and affect the overall efficiency of mineral particle sorting. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide a flotation machine scraper cleaning device to solve the problem that when the flotation machine scraper scrapes up the foam attached to the mineral particles, a small amount of mineral pulp and mineral particles are easily partially attached to the surface of the scraper due to repeated scraping and contact, thereby affecting its scraping and sorting effect on the mineral particle foam. Current flotation machines generally do not have a special cleaning device for the scraper. Generally, the scraper is disassembled, replaced or cleaned only after the mineral material sorting is completed. However, during the sorting process, the scraper is not cleaned in time, and the mineral particle foam scraped up on the scraper is not quickly cleaned away. A small amount of mineral particle foam is transferred back to the pulp surface with the scraper, which will affect the effect of scraping up the mineral particle foam next time and affect the overall efficiency of the mineral particle sorting.

[0012] As a further improvement of the above technical solution: the outer diameter of the driving wheel 1 is larger than the combined driving wheel, the driven wheel 1 and the driven wheel 2.

[0013] The beneficial effect of this improvement is that it is used to increase the transmission speed of the driven wheel 1 and the driven wheel 2, thereby increasing the rotation speed of the bristles and the spiral feeding rod.

[0014] As a further improvement of the above technical solution: the connecting rod consists of rod body one, rod body two and a spring, rod body one is fixedly connected to the sleeve, a spring is provided on the inner side of rod body one, rod body two is plug-inly connected on the side of rod body one away from the sleeve, the end of rod body two away from the sleeve is fixedly connected to the scraper, a clamping groove is provided on the end of the scraper away from the sleeve, a clamping strip is provided on the inner side of the clamping groove for sliding clamping, and a rubber scraper strip is provided on the side of the clamping strip away from the scraper.
