FIELD: gas cleaning devices; various industries. ^ SUBSTANCE: proposed device has two-section body with inlet and outlet branch pipes which is mounted on dust collecting bin. Filtration is performed by means of filtering grain layer located on gas permeable partition in form of flexible screen suspended from holding mechanism by means of cable. Holding mechanism is made in form of uprights 10 and 11 with rollers 12 and 13 located above center of each section and lever-cam 14 rotating by means of drive 18; axis of rotation of this cam lies along central axis of body. Free end of lever is provided with two rollers. At one end, cables 19 and 20 are secured in center of flexible net and at other end they are secured on upright of holding mechanism passing over roller of respective upright and rollers of lever-cam. Regeneration is performed during rotation of lever-cam creating vertical reciprocating motion of rope, thus stirring of grain layer. ^ EFFECT: increased productivity. ^ 3 dwg |
