Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the sealed dust removing device for drilling of empty set of the present utility model;
Fig. 2 is the structural representation of the empty set sealing device in Fig. 1.
The specific embodiment
As shown in Figure 1 and Figure 2, the embodiment of the sealed dust removing device for drilling of empty set of the present utility model, comprise the dust hood 3 with inner chamber, dust hood 3 front portions are connected with built-in pipe 5, rear portion is connected with empty set sealing device 2, dust hood 3 bottoms are connected with dust collecting sleeve 8, the side of dust hood 3 is connected with negative pressure generator 6, and the jet head sets 7 of dust hood 3 inner chambers is also equipped with shower nozzle and stretches at the rear portion of dust hood 3.Built-in pipe 5 links together with dust hood 3 by centering clip 4, dust collecting sleeve 8 materials are for having flexible kiss-coating canvas, jet head sets 7 180 ° of rotations as required, regulate jet head sets 7 towards the direction spraying of built-in pipe 5 imports or spray towards the direction of negative pressure generator 6 imports.
Empty set sealing device 2 comprises sleeve 11, sleeve 11 has the endoporus that is communicated with dust hood 3 inner chambers and penetrates dust hood for drilling rod, sleeve 11 front ends are drill bit upstream end, rear end is drill bit traversing through end, sleeve 11 rear and front ends are coaxially respectively equipped with brush seal circle 9, brush seal circle 9 comprise the retainer ring that is connected with sleeve 11 with on retainer ring inner peripheral surface along circumferentially distribute and radially extend internally for contact the elastomeric bristles of cooperation with drilling rod sealing, elastomeric bristles is nylon yarn.Empty set sealing device 2 also comprises that correspondence is fixedly installed on each brush seal circle 9 joint ring 10 below, joint ring 10 has the endoporus passing for hole drill bar gap, the part block of the close root of the elastomeric bristles of brush seal circle 9 fits on the leading flank of joint ring 10, and joint ring 10 is for eliminating the root gap between elastomeric bristles.
In addition, sleeve 11 is connected with the inlet suction port 12 that produces the sealing gas of shielding action to being filled with in sleeve 11 endoporus between the inner chamber of dust hood and ambient atmosphere.
During use, drilling rod 1 inserts dust hood 3 from empty set sealing device 2, from built-in pipe 5, stretches out, and built-in pipe 5 gos deep into rib, guarantees that drilling rod 1, empty set sealing device 2, dust hood 3 export, built-in pipe 5 is on same axis.During rotary drilling due to the elasticity of twice annulars sealer 9 elastomeric bristles on empty set sealing device 2, each elastomeric bristles contacts laminating with irregular drilling rod 1 each dot encapsulation, during drilling rod 1 circular motion, elastomeric bristles is followed tangent some motion, after reaching capacity, return to original position, it is tangent that new elastomeric bristles alternately forms new contact, so ceaselessly motion, forms the dynamic seal (packing) of self compensation character.And eliminate the root gap between elastomeric bristles bunch by joint ring 10.And in sleeve 11, by inlet suction port 12, be filled with the gas of 0.4～0.7 MPa, because the air pressure in dust hood 3 is negative pressure, sealing gas can produce shielding action between the inner chamber of dust hood 3 and ambient atmosphere, to reduce the impact of inside and outside differential pressure on elastomeric bristles sealing contact form.Dust collecting sleeve 8 cinder that will wet is discharged, and, due to when dust hood 6 is interior canvas contraction while there is negative pressure, is isolated from the outside simultaneously.
When drilling rod is normally drilled, a large amount of coal dusts enters in dust hood 3 by the water conservancy diversion of built-in pipe 5, two shower nozzles of jet head sets 7 towards built-in pipe 5 importers to spraying, a large amount of cinders and moistening coal dust are discharged by mud hole, the gas that negative pressure generator 6 contains coal dust and gas by residue is extracted out, by negative pressure generator 6, by gas-powered, like this methane gas is played to diluting effect, harm reduction.Jet head sets 7 180 ° of rotations as required, jet head sets to towards built-in pipe 5 importers to spraying, as round bur bar, Rhizoma Sparganii, spiral.When drilling rod can not water breakthrough, by after 180 ° of rotations of shower nozzle to negative pressure generator 6 imports sprayings, solved the problem of the scope of application.
The structure of the embodiment of empty set sealing device of the present utility model is identical with the structure of the empty set sealing device of the embodiment of the sealed dust removing device for drilling of above-mentioned empty set, repeats no more herein.
In other embodiment of the present utility model, can be provided with brush seal circle at least one place in sleeve front and back ends or sleeve, and be not limited to the twice that must relatively be located at place, sleeve front and back end, can be more than one Huo San road.In addition, the joint ring 10 of the empty set sealing device 2 in above-described embodiment, inlet suction port 12 are all the sealing effectivenesss in order to improve elastomeric bristles, and in the case of the sealing needs that meet actual condition, joint ring 10, inlet suction port 12 can be selected install or do not fill.In addition, in other embodiment of the present utility model, the retainer ring of brush seal circle 9, joint ring 10 can mutually be connected or be wholely set, or both one is located on sleeve 11, or elastomeric bristles is directly connected on sleeve 11 and retainer ring not.
