APPARATUS FOR THE MANUFACTURING OF BUILDING MATERIALS Russian patent published in 2023 - IPC B28B5/02 B07B1/28 B07B1/52 

FIELD: manufacturing of building materials; sheet materials.

SUBSTANCE: apparatus for the manufacturing of building materials comprises a screening unit, which includes at least one screening sheet having an inclination and having screening cells and a cleaning mechanism unit, which includes a scraper unit. The screening sheet is made with the possibility of making a wave-like movement when the apparatus is operating in the mode of manufacturing a building material and with the possibility of not making a wave-like movement when the apparatus is operating in the cleaning mode. The scraper block is made with the possibility of rotation and contact with the screening sheet when the device is operating in the cleaning mode and with the possibility of separating from the screening surface when the device is operating in the building material production mode. The cleaning mechanism unit additionally includes a purge unit for supplying air in the direction of the scraper unit, the purge unit being located on the upper side of the scraper unit in the direction of inclination of the screening sheet. According to the second variant of the device, the cleaning mechanism block includes a scraper block that is rotatable and in contact with the screening sheet when the device is in the cleaning mode and with the possibility of separating from the screening surface when the device is in the building material production mode, and a suction block for suction of the original building material, scraped from the screening sheet by the scraper block.

EFFECT: reduced clogging of screening sheets in the manufacture of building material.
