Description
Technical field
A kind of machining servicing unit is the utility model is related to, especially a kind of flue dustproof device.
Background technology
With expanding economy, country is also to advocate energetically to energy-saving and emission-reduction, therefore to prevent that dust is in flue in flue gas
Middle deposition, the flue gas flow rate for typically requiring flue are 10 ~ 15 meter per seconds because cause specific must reduce flue gas flow rate to 7 meters/
Second or so, inevitably dust stratification is caused in flue, and if smoke moisture is big and ash can be in cigarette when cigarette temperature is less than acid dew point
Fouling on road wallboard.Easy cleaning is not allowed after product fouling, service life shortens, under operating efficiency.
Therefore, the present inventor makes further research to this, develops a kind of flue dustproof device, thus this case produces.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of flue dustproof device, can solve the problem that prior art
Present in problem.
In order to solve the above technical problems, technical solution of the present utility model is：
A kind of flue dustproof device, including end cover, net gas intake valve, net gas venthole, outer barrel and inner cylinder；Inner cylinder is put
Put and cylindrical drum is formed in outer barrel, end cover is arranged on the both sides connection inner cylinder and outer barrel of cylindrical drum；A plurality of net gas air inlets
Valve is arranged on outer barrel, and a plurality of net gas ventholes are arranged on inner cylinder；Net gas intake valve connects with net gas venthole.
Further, net gas intake valve has appendix connection end, and appendix connection end exposes to the outer wall of outer barrel.
Further, in addition to seal washer, seal washer are arranged on the junction of net gas intake valve and outer barrel.
Further, in addition to separation frame, division rack are arranged on and a plurality of air chambers are formed between outer barrel and inner cylinder, each gas
Room includes a net gas intake valve and a plurality of net gas ventholes.
Further, net gas venthole is the aperture of trapezoidal cone shape.
Further, aperture and inner cylinder are in 15 ° ~ 30 ° of angle.
Further, end cover is fixed with outer barrel by the way of seamless welding, is bolted with inner cylinder.
Further, the net gas air inlet valve position in each air chamber has tapered gas diffusion piece.
After such scheme, the utility model sprays net gas into cylindrical drum by the net gas intake valve to gather in outer barrel,
Net gas dissipates whole inner cylindrical surface by the effect of net gas venthole can form a layer of air diaphragm so that ash will not
The fouling on wall panel, operating efficiency is effectively improved, extend life of product.

Label declaration
1 bolt hole of end cover, 11 net gas intake valve 2
The net outer barrel 4 of gas venthole 3 of the tapered gas diffusion piece 22 in appendix connection end 21
The separation frame 7 of 5 seal washer of inner cylinder 6.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.Disclosed in the utility model is
A kind of flue dustproof device, it is preferred embodiment of the present utility model as depicted in figs. 1 and 2, including end cover 1, net gas enter
Air valve 2, net gas venthole 3, outer barrel 4 and inner cylinder 5.
Inner cylinder 5, which is placed in outer barrel 4, forms cylindrical drum, and end cover 1 is arranged on the both sides of cylindrical drum, and is symmetrically distributed in
Both sides, so that inner cylinder 5 and outer barrel 4 connect.Meanwhile ensure that cylindrical drum will not gas leakage.
A plurality of net gas intake valves 2 are arranged on outer barrel 4, and a plurality of net gas ventholes 3 are arranged on inner cylinder 5；Net gas enters
Air valve 2 connects with net gas venthole 3.Net gas is sprayed into cylindrical drum by the net gas intake valve 2 to gather in outer barrel 4.
Further, net gas intake valve 2 has appendix connection end 21, and appendix connection end 21 exposes to the outer wall of outer barrel 4.
Clean gas is blown into by the tracheae being connected on appendix connection end 21.
Further, as shown in figure 4, also including seal washer 6, in order to prevent gas leakage, seal washer 6 is arranged on net gas air inlet
The junction of valve 2 and outer barrel 4.
Further, in addition to separation frame 7, division rack 7 is arranged between outer barrel 4 and inner cylinder 5, and outer barrel 4 and inner cylinder 5 it
Between form a plurality of air chambers, each air chamber includes a net gas intake valve 2 and a plurality of gas ventholes 3 only.Air chamber it is main
Effect is：First, play a part of support inwall punching net, second, after net gas intake valve 2 blows into gas, prevent because everywhere
Air pressure it is different, the excessively scattered effect for blowing into gas, reduce effect.As shown in figure 5, the net gas air inlet in each air chamber
There is tapered gas diffusion piece 22 at valve 2, gas diffusion piece 22 helps each indoor gas to be uniformly dispersed, and is unlikely to violent because blowing
It is strong to cause gas directly to be blown out from part mesh, this ensure that the inwall pressure of flue is everywhere relative to stable and uniform.
Further, as shown in figure 3, net gas venthole 3 is the aperture of trapezoidal cone shape, there is hair to the clean gas blown into
Dissipate effect.Aperture has certain gradient, i.e., aperture is in 15 ° ~ 30 ° of angle with inner cylinder, rather than is put down with the wall of flue
OK, the purpose for the arrangement is that because having a large amount of dusts in flue, dust is easier precipitation because flue be it is horizontal positioned without
It is to place vertically, so the gas that the hole with certain gradient is produced by boasting contributes to gas flow in the horizontal direction, radially
Direction helps to offset the gravity of dust, avoids dust from contacting wall.
Further, end cover 1 is fixed with outer barrel 4 by the way of seamless welding, is bolted with inner cylinder 5.
Inner side is distributed bolt hole 11 corresponding to fixing bolt on end cover 1.
The utility model interference in air flow dustproof device operation principle is as follows：First, when flue gas flows into from flue one end, do
Net gas is blown into by the tracheae being connected on appendix connection end 21, and air pressure is formed in each air chamber.Furthermore gas passes through
Net gas venthole 3 forms a layer of air diaphragm in the inner surface of inner cylinder 5 so that will not by the dust among the flue gas of flue
Touching the inner surface of inner cylinder 5 causes ash deposit and slag buildup, to reach the purpose of anti-gray deashing.
It is described above, only it is preferred embodiment of the present utility model, not technical scope of the present utility model is made
Any restrictions, therefore the change or modification done in every case according to claim of the present utility model and specification, should all belong to this practicality
Within the scope of new patent is covered.
