One end of each suspension hook is suspended on the corresponding end of a roadway section anchor rod or anchor cable, and the other end of the suspension hook fixes the cross beam; the movable hook is slidingly connected onto the cross beam; one end of the rotatable suspender is movably connected with the movable hook, and the other end of the rotatable suspender is fixed onto the ring-shaped steel tube; the ring-shaped steel tube is symmetrically provided with a plurality of the inner spray nozzles and a plurality of the outer spray nozzles; the Venturi tubes are fixed onto the ring-shaped steel tube through the metal plates and sleeve the outer spray nozzles; the inner side of the ring-shaped steel tube is provided with the water inlet connector connected with a high-pressure water pipe. The full-section rotatable mobile type negative-pressure dust collecting device achieves a full-section dust falling function and meanwhile can rotate freely and move left and right in a cross section, thereby facilitating safe passing of other mining equipment and guaranteeing safe and efficient extraction of coal mines.
Description
Technical field
The utility model relates to a kind of mine dust removing device, is specifically related to a kind of complete rotatable mobile negative-pressure dust trapping device of section.
Background technology
At present in the middle of the higher coal mining of mechanization degree, the production efficiency of fully-mechanized mining working has determined the overall manufacturing level of coal mining enterprise, but due to the very large feature of fully mechanized coal face coal dust, bring extremely severe working environment to down-hole employee, the bulk deposition of coal dust in return airway simultaneously, for follow-up cleaning work brings great difficulty, can not very effectively address this problem even if strengthen ventilation.In order effectively to alleviate staff's labour intensity, improve the working environment of down-hole, improve trouble free service coefficient, ensure that ore deposit looks forward to back production safely and efficiently, now design the rotatable mobile atomizer of full section and negative pressure dust trapping device.
Utility model content
In order to address the above problem, the utility model has adopted a kind of rotatable mobile negative-pressure dust trapping device of negative pressure being caught to dirt and the combination of atomizing de-dusting structure, thereby this structure can not only realize the effect that reaches depositing dust at full section formation water smoke barrier, and can in section, rotate freely, move left and right, improve the flexibility of device, be conducive to the safety of mining other equipment.
The utility model is achieved through the following technical solutions: a kind of complete rotatable mobile negative-pressure dust trapping device of section, it comprises annular steel pipe, inner nozzle, outer nozzle, crossbeam, movable hanger, rotatable boom, suspention hook, Venturi tube, water supply connector and panel beating.It is characterized in that: described annular steel pipe inner side is provided with multiple inner nozzles and a water supply connector, and described inner nozzle and water supply connector are symmetrically distributed in annular steel pipe inner side.Described annular steel pipe outside is symmetrically installed with multiple outer nozzles.Described Venturi tube is fixed on annular steel pipe by panel beating, and is sleeved on outer nozzle top.Described top, annular steel pipe outside is fixed with rotatable boom.Described movable hanger is the U-shaped pipe of hollow, and the described rotatable boom other end is flexibly connected with movable hanger, and movable hanger upper end sliding fit is arranged on described crossbeam.Described crossbeam two ends are fixed on suspention hook.
Described panel beating and rotatable boom are welded on respectively on annular steel pipe.
Described water supply connector is arranged on the inside front of annular steel pipe.
Described crossbeam is circular pin.
The beneficial effects of the utility model are: the utility model is caught dirt principle by negative pressure and combined with atomizing de-dusting principle, thereby realize the effect that reaches depositing dust at full section formation water smoke barrier, and can in section, rotate freely, move left and right, improve the flexibility of device, be conducive to the safety of mining other equipment.Effectively alleviate staff's labour intensity, improve the working environment of down-hole, improve trouble free service coefficient, ensure that ore deposit looks forward to back production safely and efficiently.

In figure: 1, inner nozzle, 2, annular steel pipe, 3, outer nozzle, 4, crossbeam, 5, movable hanger, 6, rotatable boom, 7, suspention hook, 8, Venturi tube, 9, water supply connector, 10, panel beating.
Detailed description of the invention
As shown in Figure 1, a kind of complete rotatable mobile negative-pressure dust trapping device of section, it comprises annular steel pipe 2, inner nozzle 1, outer nozzle 3, crossbeam 4, movable hanger 5, rotatable boom 6, suspention hook 7, Venturi tube 8, water supply connector 9 and panel beating 10.It is characterized in that: in described annular steel pipe 2 inner sides, 7 inner nozzles 1 and a water supply connector 9 are installed, described inner nozzle 1 and water supply connector 9 are symmetrically distributed in annular steel pipe 2 inner sides, and water supply connector 9 is connected with high-pressure water pipe.Described annular steel pipe 2 outsides are symmetrically installed with 8.Described Venturi tube 8 is fixed on annular steel pipe 2 by panel beating 10, and is sleeved on outer nozzle 3 tops.Described annular steel pipe 2 tops, outside are fixed with rotatable boom 6.Described movable hanger 5 is the U-shaped pipe of hollow, and described rotatable boom 6 other ends are flexibly connected with movable hanger 5, and can rotate, and movable hanger 5 upper end sliding fits are arranged on crossbeam 4.Described crossbeam 4 is circular pin, and crossbeam 4 two ends are fixed on suspention hook 7, and suspention hook 7 is suspended on drift section anchor pole or anchor cable termination.
Described panel beating 10 and rotatable boom 6 are welded on respectively on annular steel pipe 2.
Described water supply connector 9 is arranged on the inside front of annular steel pipe 2.
When work, water in high-pressure water pipe enters in annular steel pipe 2 by water supply connector 9, and the water that outer nozzle 3 sprays enters Venturi tube 8, and sprays from the other end, because overpressure reduces, reach the object of depositing dust by being combined with water in the air intake pipe with a large amount of coal dusts in section; Water sprays from inner nozzle 1 simultaneously, and formation water smoke barrier reaches the object of depositing dust.Under outer nozzle 3 and inner nozzle 1 acting in conjunction, thereby reach the object of full section depositing dust.Rotatable boom 6 drives annular steel pipe 2 on movable hanger 5, to rotate, and movable hanger 5 can move left and right on crossbeam 4, has improved the flexibility of device, is conducive to the safety of mining other equipment.
