The invention discloses a wall-hung thin type lampblack depurating
machine, which is provided with flat cuboid-shaped shell, wherein a double-
volute is arranged in the shell, and two isolated chambers of the double-
volute share an air outlet passage on the top of the shell; a turbo-fan with a horizontal output shaft is arranged in the two isolated chambers of the double-
volute respectively, and the front end of the output shaft of the turbo-fan extends out of the double-volute and is connected with at least one vertical rotary centrifugal filter screen plate; and the outside of the rotary centrifugal filter screen plate is provided with an annular oil guide ring, the bottom of the annular oil guide ring is provided with an oil leak opening, a fume flow distribution plate is arranged below the annular oil guide ring, an oil guide tank is arranged on the fume flow distribution plate, and the bottom of the shell is provided with an air inlet passage and an oil collection box. The wall-hung thin type lampblack depurating
machine has ultra-high efficiency for holding up and collecting lampblack, can basically put an end to the
pollution caused by the lampblack to the air, the shell and the external wall of a building, and has the characteristics of overall closure, simple structure, convenient cleaning, energy saving and
noise reduction, large cooking space, safe running and long service life.
