AIR PURIFICATION DEVICE Russian patent published in 2004 - IPC

FIELD: purification of air from the dust-like particles of transporting air in pneumotransporting installations.

SUBSTANCE: the invention is intended for a purification of air, in particular from the dust-like particles air in pneumotransporting installations. The device contains: a body with a storage bin; branch-pipes for intake of dusty air and withdrawal of purified air; a filtering member and a mechanism of its regeneration, that is located on the filtering member and made in the form of a fixed on the-driven shaft of the feed screw. The filtering member is made in the form of in parallel stretched strings. The feed screw on the drive side is supplied with the gear of its axial movement. The feed screw shaft is linked to an output driving element of the gear of the axial movement, kinematically connected with the pin of the pinion, the shaft of which is pivotally linked to a driving carrier. The pinion is in mesh with a fixed toothed gear wheel, and one end of the driving carrier is fixed in a bearing support of a body of an axial movement gear and its other end is connected through a connecting rod to a crank, fixed on the end of the driven shaft of the gear of the feed screw of axial movement. The crank is shifted relatively to the shaft of the driving carrier. The driven shaft of the gear of an axial movement of a feed screw is linked to the drive through a gear. In the storage bin there is a unloading gear made in the form of a pressure-relief valve installed there. The device has improved characteristics.

EFFECT: the invention allows to improve characteristics of the device.
