FIELD: environmental protection; production of the air purification devices used in the pneumatic transportation equipment. ^ SUBSTANCE: the invention is pertaining to the air purification devices, in particular, to the air purification devices used in the pneumatic transportation equipment for purification of the transported air from the dusty particle. The device contains the body with the hopper, the branch-pipes for feeding in and withdrawal of polluted and purified air, the filtering component and the mechanism of its regeneration, which is located on the filtering component and is made in the form of the feed screw. The filtering component is made in the form of the in parallel strained strings. The feed screw is established on the driving shaft with the capability of the angular and axial relocations concerning the shaft by means of the coaxially located on it the helicoidal springs, one side ends of which are fixed on the driving shaft, and other ends - on the cylindrical shell of the feed screw. The device is supplied with the fitting of the compulsory oscillations of the feed screw. The fitting of the compulsory oscillations of the feed screw contains the stop plate mounted on the butt surface of the support component of the cylindrical shell of the feed screw at the angle alpha to it and the roller fixed on the frame of the device bearing support with the possibility of interaction with the stop plate. The stop plate is made with the possibility to change the setting angle alpha, is mounted on the hinge and fixed by the bar. The roller is made out with the possibility of the adjusting relocation along the driving shaft of the feed screw. For this purpose in the threaded bush there is the mounted pusher bar of the roller. The technical result of the invention is the improved operational and technical characteristics of the air purification device. ^ EFFECT: the invention ensures the improved operational and technical characteristics of the air purification device. ^ 2 cl, 5 dwg |
