97792 PUOLIKSI SULJETTU ILMAKULJETUSJÄRJESTELMÄ97792 HALF - CLOSED AIR TRANSPORT SYSTEM
Keksinnön kohteena on raemaisen aineksen ilmakuljetinlaitteisto, joka käsittää tavallisesti keskipakoispuhaltimen ja erotussyklo-5 nin sekä näiden välisen kanaviston.The invention relates to an air conveyor apparatus for granular material, which usually comprises a centrifugal fan and a separation cyclone and a ductwork between them.
Tunnetuissa ilmakuljetinlaitteissa rakeinen aines sekotetaan kantoi Imaan puhaltimen imuaukossa, josta se ilmavirran mukana siirtyy käyttöpaikalle» missä kantoilma poistetaan laitteistosta syklonin tai suodattimen avulla. Käytännössä tästä aiheutuu kuiten-10 kin kaksi kiusallista haittaa: 1) Jos halutaan lisätä kuljettimen kapasiteettia» kasvaa myös ilmavirran mukana ympäristöön vapautuva hienopölyn määrä pur-kauspaikalla.In known air conveyor devices, the granular material is mixed at the suction opening of the carrier Ima, from where it is transferred with the air flow to the place of use »where the carrier air is removed from the equipment by means of a cyclone or filter. In practice, however, this causes two embarrassing disadvantages: 1) If it is desired to increase the capacity of the conveyor, the amount of fine dust released into the environment at the discharge site also increases with the air flow.
15 2) Jos halutaan vähentää käyttöpaikalla ympäristöön kulkeutuvaa pölypitoisuutta, on syklonien tai suodattimien erotusastetta parannettava, mikä puolestaan pienentää ilmavirtaa, koska vastus kasvaa.15 2) If it is desired to reduce the concentration of dust released into the environment at the place of use, the degree of separation of cyclones or filters must be improved, which in turn reduces the air flow as the resistance increases.
