Description
Technical field
The utility model is related to a kind of coal-feeding tube water conservancy diversion air seal set.
Background technology
It is malleation in CFBB running, in burner hearth, to prevent that high-temperature flue gas time is channeled to coal in burner hearth
Machine, burns out belt, and sealing air is connected on feeder head, and works as, and can close feeder automatically when feeder detects high temperature and go out
Mouth door.But when coal bunker burns it is empty after, due to, feeder outlet portal can not be closed in time, in burner hearth high-temperature flue gas still can anti-channeling arrive
Feeder, burns out belt.
Utility model content
The technical problems to be solved in the utility model is：In order to overcome the deficiencies in the prior art to be led there is provided a kind of coal-feeding tube
Gas seal apparatus.
The utility model solves the technical scheme that its technical problem used：A kind of coal-feeding tube water conservancy diversion air seal set, bag
Air inlet pipe, seal closure and kuppe are included, the seal closure and kuppe are circular cone cylindricality, and the seal closure and kuppe are coaxial
Set, the axis of the seal closure is vertically arranged, the lower end of the kuppe is stretched into seal closure, the outer wall of the kuppe with
The inwall formation cavity of seal closure, the air inlet pipe is arranged on the side of seal closure, the lower end of the kuppe and seal closure
Gap is provided between lower end；
The area of the seal closure upper surface is more than the area of seal closure lower surface；
The area of the kuppe upper surface is more than the area of kuppe lower surface.
Preferably, one end of the remote seal closure of the air inlet pipe is provided with flange.
Preferably, the external air blower of air inlet pipe.
Preferably, the upper end of the kuppe is provided with flange.
Preferably, the air inlet pipe is provided with valve.
The beneficial effects of the utility model are that the coal-feeding tube water conservancy diversion air seal set is passed through air in air inlet pipe, run
Cheng Zhong, pressure-air can form a downward annular sealing gland by kuppe, on the one hand can isolate connecing for coal breakage and coal-feeding tube
Touch, reduce chute blockage；Meanwhile, the sealing gland of downward injection can prevent in burner hearth that high-temperature flue gas anti-channeling is to feeder, even if there is coal
Storehouse burns empty, occurs inner flue gas of the stove anti-channeling, due to having the closing of cold air and being mixed into so that enter the flue-gas temperature of feeder not
Can be very high, so as to protect feeder belt, ensure that belt will not be burnt out.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the attachment structure schematic diagram of a kind of coal-feeding tube water conservancy diversion air seal set of the present utility model and burner hearth.
Fig. 2 is a kind of structural representation of coal-feeding tube water conservancy diversion air seal set of the present utility model.
In figure：1st, burner hearth, 2, kuppe, 3, seal closure, 4, air inlet pipe.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in figure 1, illustrating for the attachment structure of a kind of coal-feeding tube water conservancy diversion air seal set of the present utility model and burner hearth 1
Figure, the lower end of seal closure 3 is set directly at the top of burner hearth 1, and the sealing gland formed between seal closure 3 and kuppe 2 is just sealed
The flue gas that firmly burner hearth 1 is altered upwards.
As shown in Fig. 2 a kind of coal-feeding tube water conservancy diversion air seal set, including air inlet pipe 4, seal closure 3 and kuppe 2, it is described close
Sealing cover 3 and kuppe 2 are circular cone cylindricality, and the seal closure 3 and kuppe 2 are coaxially disposed, and the axis of the seal closure 3 is vertical
Set, the lower end of the kuppe 2 is stretched into seal closure 3, the outer wall of the kuppe 2 and the inwall formation cavity of seal closure 3,
The air inlet pipe 4 is arranged on the side of seal closure 3, and gap is provided between the lower end of the kuppe 2 and the lower end of seal closure 3；
The area of the upper surface of seal closure 3 is more than the area of the lower surface of seal closure 3；
The area of the upper surface of kuppe 2 is more than the area of the lower surface of kuppe 2.
Seal closure 3 and kuppe 2 are actually inverted, so design and easily cause shape between kuppe 2 and seal closure 3
Into sealing gland.
Preferably, one end of the remote seal closure 3 of the air inlet pipe 4 is provided with flange.
Preferably, the external air blower of the air inlet pipe 4.
Preferably, the upper end of the kuppe 2 is provided with flange.
Preferably, the air inlet pipe 4 is provided with valve.
Compared with prior art, the coal-feeding tube water conservancy diversion air seal set, is passed through air, air is by air inlet pipe 4 in air inlet pipe 4
Enter in the cavity between kuppe 2 and seal closure 3, in running, a downward annular sealing gland can be formed, on the one hand
Contact of the coal breakage with coal-feeding tube can be isolated, chute blockage is reduced；Meanwhile, the sealing gland of downward injection can prevent high-temperature flue gas in burner hearth 1
To feeder, even if coal bunker occur burns empty, inner flue gas of the stove anti-channeling occurs for anti-channeling, due to having the closing of cold air and being mixed into so that
Flue-gas temperature into feeder will not be very high, so as to protect feeder belt, ensures that belt will not be burnt out.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
