Description
Technical field
This utility model relates to dispersed granules filtration art, particularly to a kind of cigarette with washable fine particle filter net
Dirt fume trap cover.
Background technology
Particulate, also known as PM2.5, is that one flies away aerial particulate matter, in order to reduce the wound that human body is caused by particulate
Evil, generally uses drainage screen to intercept it.The fume amount especially produced in metallurgical technology steelmaking process is huge, needs
By the waste gas produced being processed with the smoke catching cover of drainage screen.This smoke catching cover uses kuppe relief stove
Interior flue gas is directly from by discharging.
At present, the Chinese patent of Publication No. 205164345U discloses a kind of smoke catching with detachable drainage screen
Covering, it includes outlet, and the cone-shaped hood being connected with outlet, cone-shaped hood end joint skirt cover, and skirt cover is that one side opens wide,
Other side-closed structures, are inserted with drainage screen by open side bottom skirt cover, and drainage screen is grid or grid section structure, and this blocks up
Plate constitutes enclosing cover with the closed side of skirt cover.
When the flue dust supplementary set of the detachable drainage screen of this band covers on dismounting drainage screen, owing to drainage screen is grid or grid section knot
Structure, during so drainage screen is disassembled cleaning, needs bottom whole drainage screen pull-out cone-shaped hood, owing to drainage screen needs
Filling up the large end face of whole cone-shaped hood, therefore its area is big, if working place is little, then pull-out is not easy to operation when cleaning.
Utility model content
The purpose of this utility model is to provide a kind of smoke catching cover with washable fine particle filter net, when it has dismounting
Action required space advantage little, easy-to-dismount.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of smoke catching cover with washable fine particle filter net, the airscoop shroud being connected with outlet including outlet, position
Deviate from first extension board of outlet one end, the second extension board, the 3rd extension board in airscoop shroud, also include dust-separation device, described
Dust-separation device includes the cylinder being positioned on the first extension board, the net-filter assembly being connected with the piston rod of cylinder, described net-filter assembly
Including some filtering net plates that head and the tail are hinged, the filtering net plate near piston rod removably connects with piston rod, deviates from the filter of piston rod
Mesh sheet is provided with the fixed plate for removably connecting with the second extension board, the 3rd extension board.
It is arranged such, when the gas with particulate enters airscoop shroud, first passes through dust-separation device and filter；Work as dust-separation
When needing disassembly, cleaning after device life-time service, driving cylinder, the piston rod on cylinder ejects, and executes the filtering net plate being hinged
Power, by push-tight after filtering net plate stress, owing to filtering net plate head and the tail are hinged, the filtering net plate after push-tight is by the coplanar shape of original state
State is converted to the state being mutually stacked together, and large-area filter screen becomes the filter screen of little area, now fixed plate is prolonged with second
Stretch plate, the 3rd extension board is separated, and during pull-out net-filter assembly, net-filter assembly is taken up space little, and staff can flexible operating；Again
Net-filter assembly is separated with the connection sheet on piston rod, i.e. the net-filter assembly building up little area can be taken out outside airscoop shroud.
Arrange further: described piston rod deviates from one end of cylinder and is hinged with the connecting plate for connecting filtering net plate, described
Connecting plate is removably connected by connector with filtering net plate.
Being arranged such, hinged setting can make connecting plate relatively rotate with filter screen, when filtering net plate is shunk by thrust,
Connecting plate moves therewith, it is possible to the process making push-tight filtering net plate is smooth and easy unobstructed.Connector connects and can ensure that connection is strong
While degree, it is also convenient for dismounting.
Arrange further: described fixed plate is hinged with filtering net plate, described fixed plate be provided with for the second extension board, the
The buckle that three extension boards connect, the second extension board and the 3rd extension board are provided with the draw-in groove for accommodating buckle.
Being arranged such, when the piston rod of cylinder shrinks, filtering net plate is coplanar, is covered with the large end face of whole airscoop shroud, now
Fixed plate being limited on the second extension board and the 3rd extension board by buckle and draw-in groove, in use filtering net plate is by completely
Spacing, it is difficult to loosen.
Arrange further: described buckle is positioned at fixed plate and deviates from the side hinged with filtering net plate, and described draw-in groove is positioned at second
Extension board, the 3rd extension board deviate from airscoop shroud side.
Being arranged such, when filtering net plate is straightened, fixed plate can rotate around hinged place, it is possible to turns to extend with second
Plate and the 3rd extension board bearing, now fixed plate deviates from the side hinged with filtering net plate and second and third extension board deviates from air inlet
Cover side moves closer to, and buckle and draw-in groove can cooperate.
Arrange further: described filtering net plate includes rectangle dictyosome, is coated on the rectangle screen frame of dictyosome surrounding.
Being arranged such, dictyosome is played a protective role by screen frame, the flush edge that rectangle is arranged, it is simple to the company between filtering net plate
Connect.
Arrange further: described screen frame is provided with hinge, described hinge include the first hinge eyes and the second hinge eyes, for
The 3rd hinge eyes matched with the first hinge eyes and the second hinge eyes, the width of described 3rd hinge eyes is less than the first hinge eyes
And the gap width that second between hinge eyes.
Being arranged such, when adjacent two panels filtering net plate connects, the 3rd hinge eyes of front a piece of filtering net plate is a piece of after being placed in
Between first hinge eyes and second hinge eyes of filtering net plate, reduce the gap between two filtering net plates, prevent too much particulate from
Spill between gap.
Arrange further: described hinge also includes the bearing pin being arranged in hinge.
Being arranged such, bearing pin is for connecting the first hinge eyes of later filtering net plate, the second hinge eyes and previous filter screen
3rd hinge eyes of sheet, and compared to screw element, bearing pin frictional force with hinge eyes in rotation process is little, and is not easy to hinged
The raw relative displacement of environment-development causes and comes off.
Arrange further: one end of described bearing pin is provided with for spacing folding hook portion.
Being arranged such, folding hook portion is for when bearing pin positions, owing to folding hook portion is arranged for bending, so folding hook can be by pin
Axle is stuck in hinge eyes, is limited at hinge eyes by bearing pin.
Arrange further: described outlet deviates from one end of airscoop shroud and is provided with filtering net plate.
Being arranged such, the filtering net plate of outlet can carry out secondary filter to the most filtered gas with particulate,
Effectively reduce the content of particulate in gas.
As preferably, described filtering net plate is removably connected with outlet by screw.
Being arranged such, the filtering net plate at outlet also is able to be unpicked and washed, it is simple to piles up dirt reduction after long-term use and makes
Use effect.
In sum, this utility model has the advantages that filtering net plate can either fold and can unpick and wash, and it takies
Space can flexible, it is simple to work during dismounting；The promotion of cylinder is compared to manually tightening up force evenly.
