Abstract
The utility model discloses a kind of abrasionproof dividing plate for coal powder fired boiler burner spout, it is related to coal powder fired boiler burner technical field.Including clapboard body, also include an anti-wearing ceramic part, the anti-wearing ceramic part is provided with a fixing groove and projecting part, the end of clapboard body stretches into fixing groove and positions anti-wearing ceramic part, projecting part is located at the windward side of clapboard body, set on projecting part and carve hole, set fixed carve to fix anti-wearing ceramic part and clapboard body through carving hole.The anti-wearing ceramic part is made up of carborundum.By increasing dividing plate windward side silicon carbide ceramics shoe, without removing spout repairing, extend the overall service life of dividing plate and spout.Silicon carbide ceramics can free wxpansion, solve carborundum and the casting coefficient of expansion be different causes carborundum spalling.
Description
Technical field
It the utility model is related to coal powder fired boiler burner technical field, and in particular to a kind of coal powder fired boiler burner spout
Abrasionproof dividing plate.
Background technology
The main force that pulverized coal firing boiler provides as China's electric power, indispensable effect is played in economic development,
Burner is the core of the whole combustion system of station boiler, is the key device for solving the problems, such as coal dust firing, for station boiler
Burner for, nozzle uses at present dividing plate windward side serious wear typically uses 1 year rear bulkhead wear and rupture, sternly
Blade on severe one dividing plate drops burner hearth, causes security incident.The dividing plate of serious wear needs integral replacing spout, has a strong impact on pot
Stove is run, while cost increases, causes significant wastage.
Utility model content
The technical problems to be solved in the utility model is that solve above-mentioned the deficiencies in the prior art, there is provided one kind is used for coal dust pot
The abrasionproof dividing plate of burner spout.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：One kind is used for coal powder boiler combustion
The abrasionproof dividing plate of device spout, including clapboard body, in addition to an anti-wearing ceramic part, the anti-wearing ceramic part are provided with one admittedly
Determine groove and projecting part, the end of clapboard body stretches into fixing groove and positions anti-wearing ceramic part, and projecting part is located at clapboard body
Windward side, set on projecting part and carve hole, set fixed carve to fix anti-wearing ceramic part and clapboard body through carving hole.
Further, in addition to a fixation steel plate, welded between fixation steel plate and clapboard body, it is fixed carve being arranged on it is solid
Determine on steel plate.
Further, the projecting part is in step-like, and at the step and end face of fixation steel plate offsets, projecting part it is interior
Surface fits with fixation steel plate surface.
Further, the anti-wearing ceramic part is made up of carborundum.
From above-mentioned technical proposal it can be seen that the utility model has advantages below：By increasing dividing plate windward side carborundum
Ceramic shoe, without removing spout repairing, extend the overall service life of dividing plate and spout.Silicon carbide ceramics can be certainly
By expanding, solve carborundum and the casting coefficient of expansion is different causes carborundum spalling
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of anti-wearing ceramic part in the utility model.
Embodiment
Specific embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the abrasionproof dividing plate of the present utility model for coal powder fired boiler burner spout, including dividing plate
Body 1, in addition to an anti-wearing ceramic part 2, the anti-wearing ceramic part 2 are provided with a fixing groove 3 and projecting part 4, dividing plate
The end of body 1 stretches into fixing groove 3 and positions anti-wearing ceramic part, and projecting part is located at the windward side of clapboard body, in protuberance
Set on part and carve hole 5, set and fixed carve 6 and fix anti-wearing ceramic part 2 and clapboard body 1 through carving hole 5.
In order to facilitate the fixation between anti-wearing ceramic part 2 and clapboard body 1, also also welding is solid on the windward side of clapboard body
A fixed fixation steel plate 7, it is fixed to carve 6 and be arranged on fixation steel plate, it is fixed to carve 6 and be formed in one structure with fixation steel plate 7.It is prominent
Part 4 is in step-like, and the end face at step with fixation steel plate 7 offsets, inner surface and the surface phase of fixation steel plate 7 of projecting part 4
Fitting.The anti-wearing ceramic part is made up of carborundum.
By increasing dividing plate windward side silicon carbide ceramics shoe, without removing spout repairing, extend dividing plate and spout
Overall service life.Silicon carbide ceramics can free wxpansion, solve carborundum and the casting coefficient of expansion be different causes carbon
SiClx spalling.
