BULK CATAPULT Russian patent published in 2021 - IPC B02C23/02 

FIELD: mechanical engineering; chemical industry; construction industry.

SUBSTANCE: invention relates to the field of technology intended for the ejection of bulk materials and can be used in mechanical engineering, chemical industry, in the construction industry and in other industries. The catapult consists of a sluice catapult, including a sluice housing (1), consisting of a shell (2) and two sidewalls (upper and lower) attached to the base (6). The catapult also has a rotor (11) with elastic replaceable blades (12) radially placed on it for ejection of bulk material and an eccentric (17) and a movable stop (16) fixed on the outer side of the base (6) for adjusting the elastic deformation of the blades (12). The upper sidewall has a hole (4) with a diameter of at least 0.5 of the radius of the shell (2) for feeding bulk material into the sluice body (1), and the hole (4) for feeding bulk material into the sluice body (1) is as close as possible to the shell (2). The shell (2) has an opening in the direction of rotation of the rotor (11) for ejection of bulk material.

EFFECT: catapult, while providing high performance, is characterized by low material consumption and energy consumption.
