From the above, the utility model comprises dust collect plant, communicating pipe, deduster, dust collect plant has sealing of hole, gathers dust, drifting dust, four kinds of functions of generation water smoke, select for use communicating pipe inner wall smooth, wear-resisting, tube wall is bright, resistance to compression, have flexible but unpliant steel wire transparent hose, communicating pipe is as outside the passage of carrying dust-contained airflow, the continuous gallery of dedusting especially, look the drill site layout and determine deduster riding position and communicating pipe length (being generally 3～5 meters), the optional 75～100mm of communicating pipe nominal bore.Communicating pipe internal diameter and dust collect plant, deduster connecting portion external diameter coupling, communicating pipe and the two back of pegging graft are with firm this plugging position of anchor ear bundle.
The profile of deduster is the cylinder that a top has dished (torispherical) head, deduster is made of upright leg 21, dished (torispherical) head 23 and cylinder 22, through hole 41 and the air flow inlet that the balance pressure release of dished (torispherical) head appearance is used is diagonal angle layout up and down, the flow area of through hole is communicating pipe 1～2 times of flow area, with spacing is the grid wire lath capping through hole aperture of 6～8mm, prevents that foreign matter from falling into.Dished (torispherical) head and cylinder are suit.Dished (torispherical) head top is provided with: the strainer and the decompression venting valve of spraying water, gas circuit element (being water-separating gas filter and pneumatic ball valve).In deduster inside, wrong up and down second shower nozzle 14 of layout and the thicker thick fog space that the 3rd shower nozzle 13 forms split, the middle part is the load-bearing hyoplastron switching mechanism that has balancing weight and exit passageway 17, the bottom is the grey ash bucket that falls.The end face of the hyoplastron front end of load-bearing hyoplastron switching mechanism and cylinder internal face cut the Jiao Chu lower edge and are equiped with wear-resisting, the water-fast seal 25 that is fixed on the cylinder internal face, and balancing weight is suspended on the suspension ring that are welded in the hyoplastron below by hook.The replacing balancing weight that outside protrusion arranged on the cylinder in balancing weight left side is with, openable hermatic door 28, and the unusual pendulum of balancing weight hit the generation spark when sheath 29 that the polyurethane on balancing weight top layer is made can prevent the hyoplastron upset.Need establish the cylindrical shell handgrip of two symmetries on the cylinder outer wall, be used to move deduster, the dished (torispherical) head end is symmetrical arranged two end socket handgrips and is convenient to the dimension inspection.
For making deduster stable, easy to adjust, it (is water-separating gas filter and pneumatic ball valve that dished (torispherical) head upper brace centralized arrangement has the water source treatment element (being strainer and adjustable decompression venting valve) and the gas circuit element of spraying water, the effect of pneumatic ball valve is a gas control spraying interlocking switch), the gas of deduster, water is by the gas of rig, the water supply, static pressure water in the 4th water pipe is from ground or down-hole clear water pump house, the air valve 36 of the 3rd tracheae and rig is connected, and the compressed air of rig air valve outlet enters first tracheae 10 respectively, second tracheae 37 and water-separating gas filter 35.
Working condition of the present utility model is, (diameter is greater than normally using bit diameter 15～20mm) to be drilled to 1.2～1.5 meters deep holes (concrete hole depth adds 100mm again as straight tube and cone length of tube sum) at desired location with a reaming bit earlier, dust collect plant is pushed into deep hole and uses normal drill instead after firm, drilling rod passes sealing ring 4 to begin to creep into, dust is under the compressed air effect in drilling rod core hole at the bottom of the boring hole, at the bottom of the hole through the gap of the straight tube inwall of drilling rod and dust collect plant, move to the oblique place of the tee piece of dust collect plant, the compressed air of about 0.4～0.5MPa forms behind the 4th needle-valve and the 4th shower nozzle forces jet, this jet rear portion negative pressuren zone entrainments, the boosting dust-contained airflow, dust collection capacity improves relatively, jet reduces the air-flow dust content, (hydrodynamic form 40 is the abrasion-proof stainless steel cylinder to the air-flow that dust content reduces through hydrodynamic form, the hydrodynamic form level pass through be inserted in tee piece lower part outlet in) after become staggered whirlpool, vortex row and eddy current, this eddy current fully mixes with the water smoke of first shower nozzle, 6 ejections, this mixing has the effect of elementary depositing dust, also creates good conditions for back level dedusting.Wherein, mix and to be meant big in the eddy current, granule is subjected to wet the soaking of water smoke and big back of viscosity change and powder bonded, the particle of bonding rolls the phenomenon of tying growth with dust gradually along journey and grows in intensity in communicating pipe, streamline, the flow field is disorderly more, finally the air flow inlet 11 at deduster forms more plastic particle with constant weight, these particles are moved and are reduced to thick stainless hyoplastron 12 surfaces of 3～4mm under air-flow and gravity inertial effect, under the through hole acting in conjunction that the shape that expands on the air flow inlet and balance pressure release are used, can do not raised up to by second shower nozzle 14 by the ultra-fine dust of particle bond, the bottom of the open dense fog-zone, top that the 3rd shower nozzle 13 is staggered to form, the nuclear group that ultra-fine dust and bottom, fog-zone drop bonding form is descending, become big, until tumbling to the hyoplastron surface.Hyoplastron whole upset (less than 90 °) the around the shaft when weight of hyoplastron surface area polymers increases to above the weight of balancing weight 15, accumulation comes down in torrents and falls into the ash bucket of bottom, balancing weight resets hyoplastron rapidly, thereafter repeat above-mentioned pulse action process, hyoplastron and rotating shaft weld together (upper left side area little light, the lower right side area is heavier greatly) prejudicially.Look on-the-spot the hitch point position that needs to select different balancing weights or change same balancing weight.
The air that purifies is discharged from exit passageway 17, the ash bucket 18 of hyoplastron rear end.First shower nozzle 6, second shower nozzle 14, the 3rd shower nozzle 13 are atomizer, the 4th shower nozzle 7 is a fluid jet nozzle, adjusts first needle-valve 5, second needle-valve 20, the 3rd needle-valve 19 and the 4th needle-valve 8 and make that accumulation is between dry state and the hygrometric state, the cleaned air passes qualified discharge when ash bucket is discharged.
The utility model is simple in structure, easy to adjust, water consumption is less, easy to maintenance, dust collection capacity is big, total dust efficiency of dust collection and respirable dust efficiency of dust collection are all greater than 90%, safe and reliable, can be used for having the environment of gas and dust explosion, is to utilize compressed air and water smoke that the equipment one of boring dedusting is innovated greatly under the coal mine.
