The invention discloses an oil screen
smoke hood with oil removing and
dirt purifying functions. The oil screen
smoke hood comprises a hood body, wherein a
smoke pipe is connected to the top of the hood body, and a
centrifugal fan is installed at the inner top of the hood body. According to the oil screen
smoke hood, oil stains in smoke are filtered through a continuously rotating filter screen belt, the oil stains are prevented from directly entering a
centrifugal fan, the service life of the
centrifugal fan is prolonged, and the maintenance cost of the fan is reduced; a scraper is used for carrying out primary oil removal on the filter screen belt, then the bristles on a
brush plate are used for being matched with an oil
stain cleaning agent to carry out secondary oil removal on the filter screen belt, the filtering efficiency of the filter screen belt is improved through double oil removal, and automatic equipment maintenance is achieved; and when the
smoke hood is used, flow guideplates are in a non-horizontal state, different in inclination angle and different in
suction force of the
smoke hood, when the smoke hood is in a vertical state, the
suction force is maximum and canbe adjusted according to different use environments, and when the flow guide plates are in a horizontal state, the multiple flow guide plates are spliced into a flat plate, so that the smoke hood is neat in appearance and extremely easy and convenient to clean.
