Description
Technical field
The utility model relates to a kind of powder returning and recycling device of underground mine granular powder explosive charge equipment, relates in particular to a kind of powder returning and recycling device that is applicable to underground mine granular powder explosive charge car.
Background technology
The up-hole granular powder explosive charge equipment of existing underground mine mainly adopts homemade pneumatic loading device or import explosive loading truck.Although the loading rate of these two kinds of methods is higher, its back powder rate height (reaching 10% ~ 25%) causes a large amount of wastes and the environmental pollution of explosive.With underground mine granular powder explosive charge car is example, generally is by machinery (or manpower) grug transportation tube to be aimed at the big gun hole, grug transportation tube is delivered at the bottom of the hole, big gun hole then, on one side pipe is moved back in powder charge on one side again; In powder shaped explosive charge filling process; through regular meeting because of the grug transportation tube velocity of displacement and problem such as the loading amount does not match, grug transportation tube outlet spray efficacy of a drug degree is improper or explosive viscosity is improper; make a part can turn back to the aperture along the annular space of big gun hole and grug transportation tube from the powder charge face explosive of returning that rebounds; unrestrained to ground; not only cause the explosive waste; also increased the mining integrated cost; and the downhole production environment that has been sprinkling upon on the ground residual medicine severe contamination; influence underground work personnel's physical and mental health, buried potential safety hazard simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of powder returning and recycling device of underground mine granular powder explosive charge equipment, to realize increasing substantially the back powder rate of recovery in the powder charge process, in powder charge process, can not produce dust, can not pollute the downhole production environment, guarantee underground labour's physical and mental health and consume energy to lack handling safety.
The technical solution of the utility model is: comprise the grug transportation tube that is communicated with the loading medicine storing pot, grug transportation tube passes from the center that is fixed on the pipe conveyor conduit on the pipe conveyor, one end of pipe conveyor conduit is connected with the big gun hole, it is characterized in that, an end that is connected with the big gun hole at the pipe conveyor conduit is provided with the aperture sealing shroud, an end fixing at pipe conveyor conduit and pipe conveyor is provided with a furcation area pipe, be provided with the drug blocking sealing plate in the bifurcated pipe periphery, bifurcated pipe is communicated with the back powder collection box of collecting box right-hand member by inhaling the medicine flexible pipe, collect the box left end and is connected with inlet scoop by the air-introduced machine of motor or fluid motor-driven by flange, the negative-pressure sucking of air-introduced machine generation makes back disability medicine enter into back powder collection box.
Leave an annular space that allows return air and residual medicine pass through between described grug transportation tube and the pipe conveyor conduit.
Be provided with return air dust removal by filtration bag in the described collection tank, muddy return air filters the back from the air-introduced machine exhaust outlet clean air that spues through dust settling pocket.
Described collecting box right-hand member one side is provided with collects door and chamber door locking device.Back powder collection box and dust settling pocket can conveniently be taken out from the collecting box doorway or put into.
Advantage of the present utility model: (1) can increase substantially the back powder rate of recovery in the mechanical powder charge process; Bring up to 91% ~ 95% through testing the back powder rate of recovery of the present utility model; Reduce explosive consumption and reduced the mining production cost; (2) environmental protection: can not produce dust, noise is little, and powder charge return air is carried out filtration, purification, keeps on-the-spot good operating environment, guarantees operator ' s health; (3) power consumption is few, only 1.5 kilowatts of power; (4) eliminated the potential safety hazard that unrestrained back powder explosive is on the ground buried.
Description of drawings
Fig. 1 is a structure principle chart of the present invention.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
With reference to Fig. 1, present embodiment comprises that the grug transportation tube 1, the grug transportation tube that are communicated with loading medicine storing pot 16 pass from the center that is fixed on the pipe conveyor conduit 4 on the pipe conveyor 3, leave an annular space that allows return air and residual medicine pass through between grug transportation tube and the pipe conveyor conduit.One end of pipe conveyor conduit is connected with big gun hole 2, an end that is connected with the big gun hole at pipe conveyor conduit 4 is provided with aperture sealing shroud 5, a termination that is connected with pipe conveyor 3 at pipe conveyor conduit 4 has a furcation area pipe 6, be provided with drug blocking sealing plate 7 in the bifurcated pipe periphery, bifurcated pipe is communicated with the back powder collection box 10 of collecting box 9 right-hand members by inhaling medicine flexible pipe 8, is provided with in collecting box right-hand member one side and collects door 11 and chamber door locking device 12.The left end of collecting box 9 is connected with inlet scoop by the air-introduced machine 14 of motor or fluid motor-driven by flange; In collecting box, be provided with dust-removal cloth-bag 13.Dust-removal cloth-bag filters the return air of muddiness, and the air of cleaning is discharged from air-introduced machine exhaust outlet 15.
During use, earlier back powder is collected box and put into collection tank, shut the collection chamber door, by mechanical arm the aperture sealing shroud of pipe conveyor conduit is aimed at the big gun aperture simultaneously, grug transportation tube 1 is sent at the bottom of the hole in big gun hole 2; After preparation finishes, start the air-introduced machine 14 by motor or fluid motor-driven in powder charge, in powder charge process, aperture sealing shroud 5 seals big gun aperture 2, and the residual medicine that returns with return air can't be trickled down outside; The drug blocking sealing plate that is fixed on pipe conveyor conduit bifurcated pipe periphery blocks residual medicine, the collection tank left end is drawn into return air in the big gun hole and residual medicine in the back powder collection box by the huge negative-pressure sucking of the air-introduced machine generation of motor or fluid motor-driven, and the medicinal powder centralized collection is got up; In the collecting box dust settling pocket the return air of muddiness is filtered, final, the air of cleaning is discharged from air-introduced machine exhaust outlet 15, thereby reaches zero emission.Powder charge process is closed air-introduced machine after finishing, and opens the collection chamber door, the medicinal powder that back powder is collected in the box is poured in the Bag for holding medicine, for using next time.
