Description
Technical field
The utility model belongs to fluidized-bed combustion boiler technical field of structures, particularly a kind of bell-type windshield of slip-off preventing.
Background technology
Blast cap is the requisite part of CFBB, and its major function is to make fluidized wind uniformly from fluidisation
Bed air compartment is input into burner hearth to realize fluidized bed combustion.Because blast cap location is special, the medium of its working region is high-temperature and high concentration
, in the blast cap in existing CFBB using other forms, there is blast cap head easy in the strong material of degree abrasiveness
Come off, and the increase with run time, the blast cap head quantity that comes off is more and more, so that a large amount of bed is poured in down a chimney into air compartment, serious shadow
Ring boiler normally to run.While returning the of short duration banking fire operation of boiler difficulty is brought, the continuous operation of boiler is constrained.
The main cause that blast cap head comes off is：Tied by the spot welding of external draw-in groove between former blast cap head and blast cap connecting tube
Structure is come off being fixed against blast cap head.Because the solderability of foundry goods is poor, easily produce weld crack and cause damage to come off, and apply
Welding position sets low and should not weld, and causes welding difficulty.Meanwhile, the cavity interface of blast cap head bottom is excessive, and itself and sleeve pipe boss it
Between contact face thickness less, the spacing reinforcement effect to blast cap head is very weak, if blast cap head is slightly inclined, easily under blast cap head
Portion constantly pads slag and raises blast cap head, more easily causes coming off for blast cap head.
Application No. 200520023506.0, the Chinese patent of patent entitled " easily changing chuck bell-type windshield ", provide
A kind of bell-type windshield, the utility model cover an easily changeable tubular type chuck on core pipe top, it is to avoid core pipe is particularly out
The abrasion in air port, place easy to wear for blast cap is converted into removable structure, changes chuck, extend wind after jacket wear
The service life of cap；Blast cap head, core pipe can select different materials from chuck according to condition of work, and the entirety for reducing blast cap is made
Valency；The sealing surface of two foldings is formed between blast cap head bottom and blast cap head gripper shoe, and the sealed bottom of blast cap head is good；Using draw-in groove
Matched structure with dop, simple structure, accurate positioning, easy accessibility.
Content of the invention
In consideration of it, the utility model is present for current blast cap, and blast cap head is easy to fall off, impact boiler normally continuously runs
Problem, and provide a kind of slip-off preventing, easily change, easy to operate, it is ensured that the bell-type windshield of boiler safety stable operation.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
A kind of bell-type windshield of slip-off preventing, including blast cap head, blast cap connecting tube and sleeve pipe, blast cap head is closed upper part bottom
The housing that portion is opened wide, the bottom of blast cap head have multiple vents by edge, and vent is circumferentially uniformly distributed, blast cap connecting tube
Cylindrical, blast cap headgear is arranged with the sleeve pipe of certain length located at the top of blast cap connecting tube on the outside of blast cap connecting tube upper end,
Below the vent of the blast cap head, the ring-like boss that aweather cap head inner chamber extends is provided with a certain distance from blast cap head bottom,
Casing part is provided with outside boss, and the ring-like boss inner circle gap on the inside of the cylindrical and blast cap head of boss coordinates, sleeve pipe boss
Periphery is provided with a number of convex dop outwardly, and blast cap headring type boss inner headed face is provided with a number of L-type
Interior caulking groove.
Gripper shoe is also fixed with the blast cap connecting tube, gripper shoe is rounded and is placed in blast cap head inner chamber, supports
Plate lower surface is concordant with blast cap head lower edge, upper surface is concordant with ring-like boss lower edge, the cylindrical and blast cap head bottom inner circle of gripper shoe
Gap coordinates, and gripper shoe periphery is provided with a number of convex dop outwardly, and blast cap head bottom inner headed face is provided with one
Caulking groove in the L-type of fixed number amount.
The vent is from blast cap head to outer downward-sloping setting.
The edge thickness of the blast cap headring type boss is identical or approximately the same with sleeve pipe boss edge thickness, blast cap headring
The upper surface of type boss is concordant with the upper surface of sleeve pipe boss and angle of inclination is consistent.
The quantity of the convex dop of described sleeve pipe boss and caulking groove in the L-type of blast cap headring type boss and arrangement mode phase
With.
The quantity of the convex dop of the gripper shoe and caulking groove in the L-type of blast cap head bottom inner headed face and arrangement mode phase
With.
The beneficial effects of the utility model are：
1. pass through for blast cap head and sleeve pipe to constitute an association, then assemble with blast cap connecting tube.Highly remote due to sleeve pipe
More than the thickness of blast cap headring type boss, the structure is equivalent to the height that is connected that increased indirectly blast cap head and blast cap connecting tube
Degree, along with the ring-like boss that blast cap head lower inside is arranged, also accordingly reduces the lower cavity interface size of blast cap head,
The inclination of blast cap head is thoroughly prevented, has been more conducive to realize the anti-drop function of blast cap head；
2. the utility model is remaining the lower resistance of former blast cap, anti-wear, not deslagging, outside easily changeable characteristic, is adopting
Improved structure described in the utility model scheme, makes blast cap have slip-off preventing, easily changes and easy-operating new features, also thoroughly solves
Determine and caused to damage the welding of blast cap because of solderability difference, thoroughly solved the difficult problem that blast cap head comes off, more conducively boiler
Safe and stable operation.
