Air hose is crossed with centrifugal blower outlet to be connected.Breast hole is set immediately below between air inlet and sieve.Sieve back is expansion chamber, is sunk
Drop room be divided into material room, gas chamber two parts composition, between with air permeable plate sealing separate.Gas chamber is half slot structure, and lower section sets air feed
Mouthful.Material room utilizes part slag removal tank shell, it is arranged above opening connection deduster.Dust catcher gas purifying chamber outlet connection from
Heart fan inlet.
Material is flowed into from feed inlet during work, after the stop of gate valve current limliting along the distribution of slag removal tank width range and it is natural under
Fall.The wind of centrifugal blower blowout at this time reaches air inlet through air hose, and after adjusting suitable wind speed, angle by adjusting valve, will
Naturally the powder to fall blows to the sieve being obliquely installed.Due to the effect of wind-force, the impurity such as larger particles and thin when powder falls
Powder certain drop angle since weight differential can produce.Fine powder can be blown slightly remote, and the sedimentation of back is fallen into through sieve
Room（Sieve can fall the contaminant filter partly blown afloat, be allowed to be slipped in the breast hole of lower section）.And larger particles can come to compared with
Closely, fall directly into the breast hole of lower section.The first step so utilizes the ingenious separation impurity of angle drop.Treat that powder falls into back
When expansion chamber is deposited on air permeable plate, high-pressure blast that gas chamber is passed through, being mixed into through air permeable plate in powder makes powders flowing purification, along going out
Material mouth flows out.It will be deposited in during this on air permeable plate if any failing fully erased part little particle early period, when depositing to
It can be removed when to a certain degree by access hole is opened manually.Be blown up in expansion chamber also fail to fall or blanking after and lacking of evoking
Airborne dust is measured, is upwardly into inside deduster and is filtered with air-flow by the suction that centrifugal blower produces, the dust after filtering
Drop back into expansion chamber, the air of discharge enters centrifugal blower through dust catcher gas purifying chamber, from centrifugal blower outlet reach again slag removal tank into
Continue selection by winnowing slagging-off, so circulation in air port.
The beneficial effects of the invention are as follows：The impurity such as particle, sand effectively in removing powder, can ensure air-driven chute at the same time
Conveying capacity and slagging-off effect.Greatly enhance system stability.
