Background technology
Current ore deposit groove feeding bin generally adopts belt conveyer and mobile electric dummy car to feed to each feed bin, at when filling with substance because the drop of material is large, again malleation during charging in storehouse, therefore the gas containing a large amount of dust is overflowed from feed bin inlet point, environment around gross pollution feed bin, harm operator's is healthy.
For the dust effusion phenomenon that above-mentioned when filling with substance produces, two kinds of sealing means below usual employing: first, each feed bin is provided with exhausting arm, establish a windlass main again, access dust pelletizing system, each exhausting arm is provided with switch valve, and switch valve and mobile dummy car are to any one ore deposit groove discharging chain (opening and closing), make just in the ore deposit groove of discharging, to cause negative pressure, ore deposit groove and discharge port adopt the sealing of press belt type II type sealing-tape machine simultaneously; Second, an exhausting arm is established on the discharge port side of mobile dummy car at whole ore deposit groove, this exhausting arm moves with mobile dummy car, exhausting arm other end access Mobile ventilation groove, this Mobile ventilation groove can allow exhausting arm move with mobile dummy car, exhausting groove access dust removal unit below time mobile, exhausting arm is opened all the time, make to cause negative pressure all the time in the groove of discharging ore deposit, in case flour dust overflow, discharge port and Mobile ventilation groove adopt the sealing of press belt type II type sealing-tape machine.
Above-mentioned two kinds of sealing arrangements and method all need press belt type II type sealing-tape machine, facts have proved that sealing adhesive tape easy sideslip, serious wear, maintenance load when reality uses are large, easily occur when ore deposit groove is long partially sealed less than phenomenon, affect the production run of dummy car and the sealing effectiveness of whole feed bin.
Summary of the invention
For the problems referred to above, the invention provides a kind of mobile dummy car to the sealing dust removing device of movable ore slot discharging vehicle of good sealing effect during the groove discharging of ore deposit and method.
For achieving the above object, sealing dust removing device of movable ore slot discharging vehicle of the present invention, comprise the plow-shape be arranged on dummy car feed opening to cut somebody's hair, dedust air duct is provided with on described plow-shape is cut somebody's hair, the ventilation inlet of described dedust air duct is connected with ore deposit groove, and the air outlet of described dedust air duct is connected on dust removal unit; Be respectively equipped with a channel-section steel in groove both sides, described ore deposit along groove direction, ore deposit, described in each, the track of channel-section steel is provided with the flexible sealing rubber plate of some sealings described ore deposit groove, and described flexible sealing rubber plate is symmetrical arranged relative to the line of centers of described ore deposit groove; Described flexible sealing rubber plate is by chain or be hingedly connected on described channel-section steel, and described flexible sealing rubber plate is horizontally disposed with.
