Description
Technical field
The utility model relates to coal production fields, and in particular to a kind of underground mine use wet ventilating dust-extraction unit.
Background technique
Underground mine automation examination supplies fresh wind to operation area using mechanical indentation ventilation equipment at present, stipulated that
Air duct outlet distance is met head in 5 meters, generate when " big gun head " excavation operation of fully-mechanized digging machine break up coal palisades a large amount of dust (coal dust or
Rock dust), but driving face in coal mine majority operating personnel works in fully-mechanized digging machine Background Region, and fully-mechanized digging machine working environment causes
It pollutes and distinguished and admirable flows through workspace.The dust-proof practice of tradition is to set spray for dust suppression dress apart from driving face 20 meter of -50 meter ampere of meeting head on
It sets, shortcoming is the harmful dust for being difficult to handle in distinguished and admirable in tunnel: first is that installation, mobile inconvenience, and often lag has
People operating area.To improve working environment, random movement, dust removal are installed on the scalable bridge conveyor in fully-mechanized digging machine rear portion
Air-draft-type local fan extracts fully-mechanized digging machine " big gun head " dust laden air nearby out, is discharged after dedusting to operating area, can avoid in this way
Dust laden air flows through outside operation area, substantially improves working environment and pollutes.Existing local fan ventilating dust-arrester is more
For dry dust removal, effect is poor；Or some filter devices are often provided in pipeline, however filter device mounting means is multiple
Miscellaneous, maintenance is inconvenient, leads to that filter effect variation is used for a long time, service life is short.
Utility model content
To solve the above problems, the utility model provides a kind of underground mine use wet ventilating dust-extraction unit.
The utility model is achieved through the following technical solutions:
A kind of underground mine use wet ventilating dust-extraction unit, including main air duct are provided with arc on the main air duct
Filter box, the inlet and outlet of the filter box in shifting to install up and down, and the filter box is imported and exported up and down and main air hose
Road connection is fixed, and is provided with several seepage flow holes on the curved plate of the filter box, the bottom plate of the filter box it is minimum
Place is provided with a strip-shaped hole, and there are two water-supply-pipes for the top side setting of the filter box, if being provided on the water-supply-pipe
Dry is connected to fixed jet pipe with filter box inside, and two water-supply-pipes pass through connecting tube respectively and are connected to fixation with union,
The collecting tank of opening is provided with immediately below the filter box, the collecting tank side is provided with switch gate.
Compared with prior art, the beneficial effects of the utility model are: this is practical by the way that arc is arranged on main air duct
The filter box and curved plate of shape, dust settling will be blown on curved plate and from seepage flow hole by spraying water mist by jet pipe
It flows in collecting tank, when the dust in mine is more, the dust of sedimentation can be entered from the strip-shaped hole of curved plate lowest part
Collecting tank is collected, and carries out depositing dust processing to the air in main air duct by filter box in this way, will not be to working environment
It pollutes and protects environment well, the relatively simple install convenient of the apparatus structure safeguards more convenient, mistake after long-time service
It is preferable to filter the preferable reliability of effect.
Detailed description of the invention
Fig. 1 is the schematic diagram of structure described in the utility model；
Fig. 2 is the partial structurtes diagrammatic cross-section of structure described in the utility model；
Fig. 3 is another visual angle figure in Fig. 2；
In figure: main air duct 1, filter box 2, curved plate 3, seepage flow hole 4, strip-shaped hole 5, water-supply-pipe 6, jet pipe 7, connection
Pipe 8, union 9, collecting tank 10, switch gate 11.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of underground mine use wet ventilating dust-extraction unit, including main air duct 1, the master
The filter box 2 of arc is provided in air piping 1, the inlet and outlet of the filter box 2 are in shift to install up and down, the Rose Box
About 2 body inlet and outlet are connected to fixation with main air duct 1, several seepage flow holes 4 are provided on the curved plate 3 of the filter box 2,
The lowest part of the bottom plate of the filter box 2 is provided with a strip-shaped hole 5, and there are two the top side settings of the filter box 2
Water-supply-pipe 6, be provided on the water-supply-pipe 6 several with fixed jet pipe 7, two water deliverys are connected to inside filter box 2
Pipe 6 is connected to fixation with union 9 by connecting tube 8 respectively, and the underface of the filter box 2 is provided with the collecting tank 10 of opening,
10 side of collecting tank is provided with switch gate 11.
Working principle: the utility model is in use, and exhaust fan passes through main air duct 1 for the air and dust pumping in mine
It goes out, when passing through filter box 2, the water in dust removal entered from union 9 is entered in water-supply-pipe 6 and final by connecting tube 8
It is sprayed onto the water mist that 2 lower inside of filter box forms atomization by jet pipe 7, the dust in air in main air duct 1 is sunk
Drop processing, since filter box 2, curved plate 3 are arranged using arc, water mist will be blown to dust settling on curved plate 3
And flowed in collecting tank 10 from seepage flow hole 4, when the dust in mine is more, the dust of sedimentation can be from 3 lowest part of curved plate
Strip-shaped hole 5 enter collecting tank 10, when the dirt in collecting tank 10 is more, turns on the switch 11 staff of door and carry out concentration receipts
Collection processing carries out depositing dust processing to the air in main air duct 1 by filter box 2 in this way, will not cause dirt to working environment
Dye protects environment well, and the relatively simple install convenient of the device safeguards more convenient, filter effect after long-time service
Preferable reliability is preferable.
