Abstract
The utility model provides a backup pad abrasionproof fixture block for coal burner, contains backup pad and abrasionproof fixture block, its characterized in that: the backup pad set up to the arc, backup pad front surface bilateral symmetry welding has two backup pad gussets, the backup pad gusset set up to the cross, backup pad gusset parcel in the abrasionproof fixture block, the abrasionproof fixture block set up to the U -shaped, the U -shaped is inside be provided with with backup pad gusset assorted cross -shaped groove. The utility model discloses a silica combines the abrasionproof fixture block of carbonization silicon pottery material, silica miropowder, silicon carbide particle, ceramic fibre intensive mixing, and through ramming process, dry back, the high -sintering forms, wherein does silica account for 10% does 15%, carborundum account for 80% 90%, having wear -resisting oxytolerant heat -transmission, to shake stability good, and the cost is low, and effectual protection backup pad gusset is not is not worn and torn, the backup pad gusset passes through cross grafting mode with the abrasionproof fixture block to be connected, and is provided with the elastic material bonding in the junction for the connection fastening of product.
Description
Technical field
The utility model belongs to mechanical field, is specifically designed a kind of spiral winding piece wheel piece.
Background technology
Burner (or burner) is the indispensable core apparatus of combustion furnace kiln plant, and its performance is excellent with structure
Whether directly influence the fuel availability of stove, the thermal efficiency and whether meet the requirement of energy-conserving and environment-protective.For using diffusion
The burner of combustion system has completed progressively to be transitioned into the rectangular burner of comb shape air nozzle from sleeve type burner
Conversion, and develop into the annular multiple nozzle spraying eddy flow mixing steady flame combustion technology of backflow preheating or annular multiinjector interlocks upper spray
The steady flame overheavy firing technology of air-flow turn-back pre-heating after premixed combustion.The damageable zone of current coal burner uses heat-resistance and wear-resistance steel
Make, anti-wear performance can not meet requirement, serious only cannot be just continuing with using 2,3 months because wearing and tearing, important to center
Fixed formation threatens the safety of part, more allows the overall performance of burner cannot be guaranteed.Supporting plate in burner uses resistance to
Hot abrasion-resistant stee is made, and protective case is cased with outside it, but protection Analysis of Nested Design is unreasonable, it is easy to is come off, is not played not only
The effect of protection, while the protective case for dropping influences the use of burner.
The content of the invention
The purpose of this utility model provides a kind of coal dust firing and enables supporting plate abrasionproof fixture block, solves above technology and asks
Topic.
What the purpose of this utility model was realized in：A kind of coal burner supporting plate abrasionproof fixture block, comprising support
Plate and abrasionproof fixture block, it is characterised in that：Described supporting plate is set to arc, and the preceding surface of supporting plate is symmetrical to be welded with two
Supporting plate gusset, described supporting plate gusset is set to cross, and described supporting plate gusset is wrapped in abrasionproof fixture block, institute
The abrasionproof fixture block stated is set to U-shaped, and U-shaped is internally provided with the cross bath matched with supporting plate gusset.
Described abrasionproof fixture block material is set to silicon-carborundum ceramics, described abrasionproof fixture block and supporting plate muscle
The contact surface of plate sets resilient material bonding.
Described supporting plate is set to circular arc, and arcuate surface is symmetrically set between being located at two supporting plate gussets
Four supporting plate mounting holes.
The utility model uses the abrasionproof fixture block of silicon-carborundum ceramic material, fine silica powder, carborundum
Particle, ceramic fibre are sufficiently mixed, and through ramming process, after drying, high temperature sintering is formed, and wherein silica accounts for 10%-15%,
Carborundum accounts for 80%-90%, good with wear-resisting resistance to oxidation heat shaken stability, and low cost, is effectively protected supporting plate gusset not
It is worn；Supporting plate gusset is connected with abrasionproof fixture block by cross inserting mode, and it is viscous to set resilient material in junction
Connect, it is to avoid silicon-carborundum ceramic ring, in use because expansion rate is different, and causes silica from metal parts
Silicon carbide ceramic ring spalling comes off so that the connection fastening of product.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Fig. 2 be Fig. 1 in abrasionproof fixture block A to schematic diagram.
Fig. 3 be Fig. 1 in supporting plate A to structural representation.
In figure：1st, supporting plate, 2, supporting plate gusset, 3, supporting plate mounting hole, 4, abrasionproof fixture block.
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：A kind of coal burner supporting plate abrasionproof fixture block, comprising supporting plate 1 and abrasionproof fixture block 4, it is special
Levy and be：Described supporting plate 1 is set to arc, and the preceding surface of supporting plate 1 is symmetrical to be welded with two supporting plate gussets 2, institute
The supporting plate gusset 2 stated is set to cross, and described supporting plate gusset 2 is wrapped in abrasionproof fixture block 4, described abrasionproof card
Block 4 is set to U-shaped, and U-shaped is internally provided with the cross bath matched with supporting plate gusset 2, using cross socket connection,
So that connection is reasonable.
The described material of abrasionproof fixture block 4 is set to silicon-carborundum ceramics, is effectively protected supporting plate gusset
It is not worn, extends its service life；Described abrasionproof fixture block 4 sets resilient material and glues with the contact surface of supporting plate gusset 2
Connect, it is to avoid silicon-carborundum ceramic ring, in use because expansion rate is different, and causes silica from metal parts
Silicon carbide ceramic ring spalling comes off.
Described supporting plate 1 is set to circular arc, and arcuate surface is symmetrical set between being located at two supporting plate gussets 2
There are four supporting plate mounting holes, be easy to being connected for supporting plate 1 and burner.
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.
