Abstract

Wewnątrz walcowatego kosza osłonowego (1), na trójniku złączeniowym (2), do którego przyłączona jest instalacja przewodów sprężonego powietrza (3), zamocowany jest wirnik (4). Wirnik (4) ma wydrążony trzpień, na którym osadzona jest tuleja, która od góry ma pierścień czołowy zabezpieczony śrubą blokującą ampulową. Tuleja ma dwa naprzeciwległe przelotowe otwory, w których zamocowane są rurkowe dysze o średnicy otworu 8 mm, do których dospawane są łopatki hamujące. Kosz osłonowy (1) ma od zewnątrz dwa naprzeciwległe zawiesia (11), do których od spodu kosza osłonowego (1) zamocowana jest belka (12) do instalacji (13) przewodów sprężonego powietrza. Łopatki hamujące wspomagają rozrzucanie powietrza, powodując równomierny nadmuch w orbicie wirnika. Urządzenie ma zastosowanie w górnictwie do rozrzedzania metanu za pomocą sprężonego powietrza wprawionego w ruch turbulentny.Inside the cylindrical shielding basket (1), on the connecting tee (2), to which the compressed air pipe installation (3) is connected, the rotor (4) is mounted. The rotor (4) has a hollow shaft on which a sleeve is mounted, which has a front ring secured from the top with an Allen locking screw. The sleeve has two opposite through holes, in which tubular nozzles with a hole diameter of 8 mm are mounted, to which braking blades are welded. The shielding basket (1) has two opposite suspensions (11) on the outside, to which a beam (12) for the compressed air pipe installation (13) is attached from the bottom of the shielding basket (1). The braking blades support the air dispersion, causing uniform blowing in the rotor orbit. The device is used in mining to dilute methane using compressed air set in turbulent motion.
