Abstract
Sposób przygotowania mieszanki pylowo-powietrznej do opylania wyrobisk górniczych charakteryzuje sie tym, ze zasysany z pojemnika proszkowa pompa membranowa (1) pyl mineralny (7) jest fluidyzowany wtryskiem powietrza (9) w obrebie co najmniej jednego zaworu kulowego (8) komory ssaco - tloczacej (5) proszkowej pompy membranowej (1), a nastepnie tak wytworzony fluidyzowany pyl mineralny (11) rura podawcza (12) jest dostarczany do trójnika mieszajacego (16) skad strumien sprezonego powietrza (SP) dostarczanego rurociagiem (17), transportuje mieszanine pylowo -powietrzna przy pomocy rurociagu podawczego (23) do dyszy rozpylajacej (24). Urzadzenie do opylania wyrobisk sklada sie z proszkowej pompy membranowej (1) gdzie wylot fluidyzowanego pylu mineralnego (11) z proszkowej pompy membranowej (1) podlaczony do koncówki rury podawczej (12) osadzonej drugim koncem w trójniku mieszajacym (16) zamontowanym w ciagu trasy rurociagu sprezonego powietrza (17) zaopatrzonego w zawór odcinajacy (19), trójnik (20) z króccem redukcyjnym (15) podlaczonym do przewodu sprezonego powietrza (13) z zaworem regulacyjnym (14) zasilajacego sprezonym powietrzem rozdzielacz (3) napedu proszkowej pompy membranowej (1), zaworu zwrotnego (22) zamontowanego pomiedzy zaworem regulacyjnym (21) i trójnikiem mieszajacym (16), do którego polaczony jest rurociag podawczy (23) i dysza rozpylajaca (24).The method of preparing the dust-air mixture for dusting mining excavations is characterized by the fact that the powder membrane pump sucked from the container (1) mineral dust (7) is fluidized with air injection (9) within at least one ball valve (8) of the suction and pumping chamber (5) the powder membrane pump (1), and then the fluidized mineral dust (11) thus formed, the feed tube (12) is supplied to the mixing tee (16), from where the compressed air stream (SP) supplied by the pipeline (17) transports the dust mixture air by means of a supply pipe (23) to the spray nozzle (24). The excavation dusting device consists of a powder membrane pump (1) where the fluidized mineral dust outlet (11) from a powder membrane pump (1) connected to the end of the feed pipe (12) mounted with a second end in a mixing tee (16) installed along the pipeline route compressed air (17) supplied with a shut-off valve (19), T-piece (20) with reducing adapter (15) connected to the compressed air line (13) with a control valve (14) supplying compressed air to the manifold (3) of the diaphragm pump powder drive (1) ), a non-return valve (22) mounted between the control valve (21) and the mixing tee (16), to which the inlet pipe (23) and the spray nozzle (24) are connected.
