The utility model has the advantages of simple structure, be provided with three thickening gusset between apron and sleeve for add the deformation that reduces sleeve and apron man -hour, the sleeve is inside smooth, reduce with the frictional force of buggy, improve the life of product, be provided with the threaded holes and seal groove on the flange, improve the sealing performance that the product used, reduce air pollution when using.
Description
Technical field
The utility model belongs to mechanical field, more particularly to coal burner wear strip.
Background technology
Coal burner elbow be located at power station boiler burner First air coal dust channel in, be connected to power transportation pipe and
Air channel of burner, while elbow part wall just washes away direction to coal dust, easily produces abrasion, jeopardizes burner operation peace
Entirely.Therefore, rational structure is designed, can effectively protects combustor elbow to wear and tear, while burner First air can be facilitated again
The installation and maintenance of consumable accessory in road, with very practical realistic meaning.
The patent of Application No. CN200920047954.2 discloses a kind of elbow anti-wear plate for pulverized coal burner, by center
Sleeve D, flange face A, semicircle cover plate B are constituted, and flange face A is 30-40 ° with the angle α of horizontal plane, and center is provided with center
Sleeve D, its top is provided with semicircle cover plate B, and lower section is provided with bottom-thickened gusset C.The utility model is easy for installation, not only
The wear-out life of combustor elbow can effectively be extended, increased the service life, and can conveniently make in burner consumable accessory overall from
Dismantled outside stove, install and safeguard very convenient.But in process of production, sleeve D with flange welding when easily deform, using
When, sometimes have micro coal dust and spill, influence the quality and real-world environment of product.
The content of the invention
The purpose of this utility model provides coal burner wear strip, solves above technical problem.
What the purpose of this utility model was realized in：Coal burner wear strip, comprising flange, flange upper end right side
Cover plate is provided with, described cover plate lower end is arranged with sleeve weld in parallel in flange right side, it is characterised in that：Described sleeve with
Three reinforcements are evenly arranged between cover plate, the supporting thickening gusset that is provided with of sleeve extends to sleeve and flange intersection；It is described
Flange be set to ellipse, oblong surface is provided with two seals groove, and seal groove surrounding is provided with six in ellipse
Mounting hole.
Described reinforcement is set to rectangle, and described rectangle is provided with rounding angle with sleeve and cover plate intersection.
Described two seals groove intermediate distance is 10mm, and seal groove is set to semicircle, and described semicircle radius sets
It is set to 1mm.
The inner arm of described sleeve is smooth.
Described flange is set to 15 ° with the centerlines of sleeve.
Simple structure of the present utility model, is provided with three reinforcements between cover plate and sleeve, and set is reduced during for processing
Cylinder and the deformation of cover plate；Sleeve inner is smooth, reduces the frictional force with coal dust, improves the service life of product；Set on flange
There are screwed hole and seal groove, improve the sealing property that product is used, air pollution when reduction is used.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the right view of Fig. 1.
Fig. 3 is I close-up schematic views of the present utility model.
In figure：1st, flange, 2, thicken gusset, 3, sleeve, 4, reinforcing plate, 5, cover plate, 6, seal groove.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, but not as to limitation of the present utility model：
During specific implementation：Coal burner wear strip, comprising flange 1, the upper end of flange 1 right side is provided with cover plate 5, described
The lower end of cover plate 5 be arranged with sleeve 3 in parallel and be welded in the right side of flange 1, it is characterised in that：It is uniform between described sleeve 3 and cover plate 5
Three reinforcements 4 are provided with, the supporting thickening gusset 2 that is provided with of sleeve 3 extends to sleeve 3 and the intersection of flange 1；Described flange
1 is set to ellipse, and oblong surface is provided with two seals groove 6, and the surrounding of seal groove 6 is provided with six installations in ellipse
Hole, is bolted the firmness and sealing property that product connection is improve with the structure design of seal groove 6.
Described reinforcement 4 is set to rectangle, and described rectangle is provided with rounding with sleeve 3 and the intersection of cover plate 5
Angle.During specific implementation, during assembled spot welding, by reinforcement, 4 points are welded between sleeve 3 and cover plate 5, and reinforcement 4 is used to reduce production
Process middle sleeve 3 and the welding deformation amount of cover plate 5, after the completion of sleeve 3 and cover plate 5 are welded with flange 1 respectively, can be dismantled.
The described intermediate distance of two seals groove 6 is 10mm, and seal groove 6 is set to semicircle, described semicircle radius
1mm is set to, when mounted using the fluorubber of Wear-resistant, high-temperature resistant in seal groove 6, the sealing property that wear strip is installed is improved.
The inner arm of described sleeve 3 is smooth, reduces the friction with coal dust, extends the service life of product.
Described flange 1 is set to 35 ° with the centerlines of sleeve 3, and this structure design is conducive to wear strip with burning
The installation of device elbow.
Above-described embodiment is only intended to clearly illustrate the utility model description, and not to the limit of implementation method
It is fixed, to those of ordinary skill in the art, the change of other multi-forms can also be made on the basis of the above description
Or change, there is no need and unable to be exhaustive to all of implementation method, and the obvious change thus amplified out
Or among changing still in protection domain of the present utility model.
