Abstract
The utility model discloses an air duct collector for coal mine, which comprises a dust collecting cavity enclosed by a casing. The dust collecting cavity is provided with an air inlet and an air outlet, the air outlet is provided with an electric air exhaust fan, a secondary filter layer is disposed on the air outlet on the front of the electric air exhaust fan, a primary filter layer is disposed on the air inlet, the filter aperture of the primary filter layer is larger than that of the secondary filter layer, a dust discharge passage in the shape of a chute is arranged on the bottom of the dust collecting cavity, and a discharge opening on the lower portion of the dust discharge passage can be sealed on a bottom cover via a retractable manner. The air duct collector for coal mine adopts a structure of combining the dust collecting cavity with the electric air exhaust fan, utilizes the primary filter layer to generate negative pressure inside the dust collecting cavity to absorb duct in space, enables air to become clean by aid of two steps of filter and duct collection, can effectively eliminate coal duct in work space, can move arbitrarily according to needs due to small volume, improves work efficiency, keeps air clean and reduces harm of the dust to work staff.
Description
Technical field
The utility model relates to a kind of safety of coal mines environmental protecting device, and particularly a kind of colliery is with aerial dust dust catcher.
Background technology
Coal will be main energy sources in quite long period.Safety of coal mines and environmental protection are the necessary conditions of colliery ordinary production, can guarantee that coal industry continues, stable, sound development.In progress of coal mining, dust pollution is to the harm of human body and a kind of colliery pollution sources that come into one's own gradually.
In progress of coal mining, dust pollution is inevitable, for solving the pollution that dust causes, generally adopt deduster to carry out dedusting in the prior art, and the specific aim of these dedusters is stronger, is mainly used in dedusting use in the smoke dust duct, does not have the space dedusting function.And in the working space in colliery, dust is to float in the air, thereby the deduster of prior art can't be suitable for.Cause for a long time, the workers with long time in the coal mine working space is perplexed by coal dust.
Therefore, need a kind of colliery, can remove the coal dust of working space, and can arbitrarily move as required, keep the cleaning of air, reduce the harm of dust the staff with aerial dust dust catcher.
The utility model content
In view of this, the utility model provides a kind of colliery with aerial dust dust catcher, can remove the coal dust of working space, and can arbitrarily move as required, keeps the cleaning of air, reduces the harm of dust to the staff.
Colliery of the present utility model is with aerial dust dust catcher, comprise the dust-collecting cavity that surrounds by housing, dust-collecting cavity is provided with exhaust outlet and air inlet, described exhaust outlet is provided with electronic air exhauster, the secondary filter layer before being positioned at electronic air exhauster, exhaust outlet is set, air inlet is provided with the primary filter layer, and the pore size filter of described primary filter layer is greater than the pore size filter of secondary filter layer; The dust discharge passage of chute shape is made in described dust-collecting cavity bottom, but dust discharge passage bottom discharging opening seals in the mode of folding bottom is set.
Further, described primary filter layer bottom is obliquely installed causing dust plate to airintake direction from top to bottom, and the causing dust plate lower end is stretched in the dust collecting trough of causing dust plate bottom setting;
Further, but described dust-collecting cavity top seal in the mode of folding top cover be set;
Further, the suction surface of described primary filter layer and secondary filter layer is by upwards being obliquely installed to sucking direction down.
The beneficial effects of the utility model: colliery of the present utility model is with aerial dust dust catcher, adopt dust-collecting cavity and electronic air exhauster structure combining, and utilize the primary filter layer in dust-collecting cavity, to produce negative pressure, absorb dust in the space, and by two-layer dust removal by filtration, make air become clean, can effectively remove the coal dust of working space, because volume is less, can can arbitrarily move as required, increase work efficiency, keep the cleaning of air, reduce the harm of dust the staff.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Accompanying drawing is a structural representation of the present utility model, as shown in the figure: the colliery of present embodiment is with aerial dust dust catcher, comprise the dust-collecting cavity 1 that surrounds by housing, dust-collecting cavity 1 is provided with exhaust outlet and air inlet, described exhaust outlet is provided with electronic air exhauster 3, before exhaust outlet is positioned at electronic air exhauster 3 secondary filter layer 2 is set, air inlet is provided with primary filter layer 7, and the pore size filter of described primary filter layer 7 is greater than the pore size filter 2 of secondary filter layer; The dust discharge passage of chute shape is made in described dust-collecting cavity 1 bottom, but dust discharge passage bottom discharging opening seals in the mode of folding bottom 4 is set.
During use, dust laden air enters dust-collecting cavity 1 by primary filter layer 7 under 3 effects of electronic air exhauster, and primary filter layer 7 filters out the bigger dust of particle diameter, and is beneficial to and keeps in the dust-collecting cavity 1 high negative being arranged, and is beneficial to dust-collecting cavity 1 efficient operation; Air in the dust-collecting cavity 1 is discharged by exhaust outlet through electronic air exhauster 3, and filters 2 by the secondary filter layer, removes remaining small particle diameter dust, and is discharged by the dust discharge passage.
In the present embodiment, described primary filter layer 7 bottom are obliquely installed causing dust plate 6 to airintake direction from top to bottom, and causing dust plate 6 lower ends are stretched in the dust collecting trough 5 of causing dust plate bottom setting; The bigger grit of particle diameter under secondary filter layer 2 filters drops in the dust collecting trough along causing dust plate 6, is beneficial to the protection environmental sanitation.
In the present embodiment, but described dust-collecting cavity 1 top seal in the mode of folding top cover 8 be set, the convenient incrustation of removing in the dust-collecting cavity 1 keeps the useful space of dust-collecting cavity 1;
In the present embodiment, coming off of back dust filtered by upwards being obliquely installed to sucking direction down, being beneficial in the suction surface of described primary filter layer 7 and secondary filter layer 2, reduces disposal costs.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
