The specific embodiment
Below in conjunction with accompanying drawing one embodiment of the present of invention are further described:
Dry sand of the present invention storehouse device for discharging mainly is made of discharge duct 1, discharge valve and leakage material Through Flow Line (TFL) 8; Described discharge duct 1 is integral by two joint straight tube weldings up and down, wherein go up the lower right surface that straight tube vertically is fixed on valve body 3, and lower straighttube tilts to be fixed on the lower end of straight tube, and the two angle α that save straight tubes are 145 ~ 155 ° up and down; Be welded with a semicircle flute profile brace panel on the lower semi-circular surface, top of lower straighttube.Described discharge valve comprises valve body 3, sealing arrangement 5, bulkhgead gate 6 and cylinder 9, valve body 3 is connected into left and right two box type constructions by a plurality of steel weldings, right case top is bolted on the lower end mount pad in dry sand storehouse 4, the bottom has been bolted discharge duct 1, inner parallel 3 axles that are equipped with, each slidingly is equipped with a holder pulley 2 on the every axle; The bottom of left box body is processed with Lou material mouth, and inside is equipped with two guide wheel group 7 by four anchor shafts, and each guide wheel group 7 comprises the pulleys of two sliding dresses; The piston rod of bulkhgead gate 6 left ends and cylinder 9 is hinged and connected, and oblique prone wedge angle is processed in the right part, passes successively two guide wheel group 7 and is sandwiched among the sealing arrangement 5 afterwards; Sealing arrangement 5 comprises sealing member 5-1, briquetting 5-2 and set screw 5-3, has two covers, is installed in symmetrically the up and down both sides of bulkhgead gate 6; Sealing member 5-1 is clipped between two angle steel, and carries out the spacing of above-below direction by set screw 5-3 and briquetting 5-2.Described leakage material Through Flow Line (TFL) 8 comprises upper conical pipe and downtake, and upper conical pipe upper end is fixed on the leakage material mouth place below the left box body of valve body 3, and the lower end of downtake is connected with the lower straighttube of discharge duct 1.
Principle of work: when carrying out discharging, control cylinder 9 orders about bulkhgead gate 6 and bounces back in the left box-like body of valve body 3, with the passage conducting between dry sand storehouse 4 and the discharge duct 1, dry sand material in the dry sand storehouse 4 falls into the lower straighttube that is in tilted layout through the upper straight tube of discharge duct 1, and the dry sand material of free fall is carried out buffer deceleration.
When not needing discharging, control cylinder 9 orders about bulkhgead gate 6 and moves to right, and by guide wheel group 7 directional taggings, inserts in the dry sand material stream of whereabouts, until with the passage Close All between dry sand storehouse 4 and the discharge duct 1 along each holder pulley 2 successively.
When increasing because of wearing clearance between bulkhgead gate 6 and the sealing, its gap can compensate by sealing regulating, namely unscrew the jam nut on the set screw 5-3, again with set screw 5-3 precession certain distance, sealing member 5-1 is close on the bulkhgead gate 6; The sand material that spills during for bulkhgead gate 6 retraction can fall into discharge duct by leaking the material Through Flow Line (TFL), prevents that it from impacting cylinder.
