FIELD: glass production.
SUBSTANCE: invention relates to methods for granulating glass, it can be used in the production of glass containers and other glass products. The method involves feeding molten glass and defective hot glass products into a granulator bath filled with cold water, in which the hot glass is crushed by thermal shock. Inside the bath there is a scraper conveyor, to the two traction chains of which scraper elements are attached that transport the glass granulate to the inclined gutter of the bath, located in the granulator discharge zone. The initial height of the scraper elements provides a gap of 20-25 mm between their lower edges and the bottom of the bath. In this gap, a bottom insulating layer of glass granulate is formed, which prevents abrasive wear of the bath bottom when the scraper elements move and the glass granulate is moved. For mechanized cleaning and removal of the insulating layer contaminated with silt deposits, several (one scraper element for 5-8 m of the conveyor length) of the initial scraper elements are replaced with scraper elements having a height of 20-25 mm more. These scraper elements in the process of movement rake out the contaminated glass granulate and move it to the discharge area, where it is redirected from the conveyor of the cullet recycling line to the bucket using the flow switch. Cleaning of the granulator is carried out at a reduced speed of the scraper conveyor by 20-30% and lasts 10-15 minutes. After cleaning, the scraper elements that are 20-25 mm higher than the others are replaced with the initial scraper elements.
EFFECT: increase in the reliability and service life of the scraper granulator, as well as mechanization and facilitation of the process of cleaning the granulator bath from contaminated glass granulate.
