Description
Technical field
Detachable shoe the utility model relates to boiler plant technical field, on especially a kind of coal spout.
Background technique
Circulating fluidized bed boiler, using the highest clean coal combustion technology of industrialization degree.Circulating fluidized bed boiler
Using fluidized combustion, primary structure includes combustion chamber (including emulsion zone and dilute-phase zone) and circulation melts down (including high-temperature gas-solid
Separator and revert system) two large divisions.Maximum difference with bubbling fluidized bed combustion technology is operating air velocity height, enhances combustion
Burn and the heterogeneous reactions process such as desulfurization, boiler capacity can be expanded to power industry acceptable large capacity (600MW or with
Upper grade), the circulating fluidized bed boiler underlying issues such as very good solution calorifics, mechanics, materialogy and expansion, abrasion,
The engineering problems such as overtemperature become fire retardant solid fuel (such as gangue, oil shale, municipal refuse, mud and other wastes) energy
The advanced technology that source utilizes.
Coal is usually inputted boiler by coal spout by the coal supply system of circulating fluidized bed boiler.Due to boiler coal feeding vertical drop
Impact wear is caused to the coal breakage inclined tube section of underface, is easy coal breakage tube bottom plate worn out, has seriously affected boiler and normally given birth to
Operation is produced, production efficiency is reduced.
Utility model content
The applicant provides the detachable abrasionproof dress on a kind of coal spout for the disadvantage in above-mentioned existing production technology
It sets, to pass through fast quick-detach, replace wear-resistant block and achieve the effect that coal spout and be used for a long time.
Technical solution used by the utility model is as follows:
A kind of detachable shoe on coal spout, including coal spout, the coal spout is at bending structure, in coal breakage
It is provided with rectangular opening in bottom of the tube one side wall, is vertically installed with corresponding rectangular frame at the rectangular opening outward, under rectangular frame
Square inner side is equipped with one block of supporting plate, and the upper port exterior rim of the rectangular frame is equipped with connecting flange, the supporting plate
Top surface is equipped with blind flange, and the outer ring of the blind flange is locked by gasket and fastener and connecting flange, the blind flange
Outer end face middle position is equipped with handle, is equipped with wear-resistant block in the space formed inside the blind flange and rectangular frame.
Its further technical solution is:
The rectangular frame passes through the first steel plate and the second steel plate welding besieged city quadrilateral structure.
Handle is welded in the outer end face middle position of the blind flange, forms first between root part of handle and blind flange outer end face
Solder joint.
The top surface of the supporting plate and blind flange inner face form the second solder joint using welded connecting.
The inner ring of the upper port exterior rim of the rectangular frame and top surface and connecting flange forms the using being welded to connect
Three solder joints.
The beneficial effects of the utility model are as follows:
The utility model is compact-sized, reasonable, easy to operate, by installing wear-resistant block on the side wall of coal breakage bottom of the tube,
And using the type of attachment of bolt fastener, prefabricated wear-resistant block can be with quick-replaceable.Therefore it can reach coal spout long-time service
Effect.

Specific embodiment
With reference to the accompanying drawing, illustrate specific embodiment of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the detachable shoe on the coal spout of the present embodiment, including coal breakage
Pipe 1, coal spout 1 are provided with rectangular opening on 1 bottom side wall of coal spout, are vertically installed with outward at rectangular opening at bending structure
Corresponding rectangular frame 4,4 lower section inner side of rectangular frame are equipped with one block of supporting plate 3, the upper port exterior rim of rectangular frame 4
Connecting flange 8 is installed, the top surface of supporting plate 3 is equipped with blind flange 6, and the outer ring of blind flange 6 passes through gasket 5 and fastener and connection
Flange 8 is locked, and the outer end face middle position of blind flange 6 is equipped with handle 7, the space formed inside blind flange 6 and rectangular frame 4
Wear-resistant block 2 is inside installed.
Rectangular frame 4 passes through the first steel plate 401 and the second steel plate 402 welding besieged city quadrilateral structure.
Handle 7 is welded in the outer end face middle position of blind flange 6, forms first between 6 outer end face of 7 root of handle and blind flange
Solder joint 9.
The top surface of supporting plate 3 and 6 inner face of blind flange form the second solder joint 10 using welded connecting.
The inner ring of the upper port exterior rim of rectangular frame 4 and top surface and connecting flange 8 forms third using welded connecting
Solder joint 11.
The specific structure of the utility model are as follows: rectangular opening is opened on 1 bottom edge of coal spout, and steel plate group is welded into rectangle frame one end along coal breakage
1 bottom edge rectangular opening of pipe welds the other end and connecting flange 8 welds, and supporting plate 3 and handle 7 and blind flange 6 weld, and gasket 5 is placed in
Between connecting flange 8 and blind flange 6, wear-resistant block 2 is placed in blind flange 6 and 4 groups of rectangular frame are welded into rectangle frame, 6 He of blind flange
The bolt of connecting flange 8, nut and the connection locking of gasket 5.
The working principle of the utility model are as follows:
As long as being unloaded when wear-resistant block 2 is using bolt is removed when being influenced to convey to coal after a period of time by the abrasion of coal
Then prefabricated wear-resistant block 2 is changed and is resetted together with blind flange 6 by blind flange 6 and wear-resistant block 2, can so reach coal breakage
The effect that pipe is used for a long time.Therefore it can achieve the effect that coal spout is used for a long time.
