Abstract
The utility model relates to an expansion joint, in particular to an expansion joint used in the connection position of a bottom slag pipe and a slag inlet pipe of a slag cooler, and aims to solve the problem that the service life is short due to the fact that dust is prone to accumulation in a metal expansion joint in the prior art. The expansion joint used in the connection position of the bottom slag pipe and the slag inlet pipe of the slag cooler comprises a corrugated pipe arranged between the bottom slag pipe and the slag inlet pipe of the slag cooler, wherein an inner slag pipe which is communicated with the bottom slag pipe and used for protecting the corrugated pipe is arranged in the corrugated pipe; the lower end of the corrugated pipe is flush with the upper end of the slag inlet pipe; and a cavity body formed by the inner slag pipe and the corrugated pipe is communicated with the slag inlet pipe of the slag cooler. According to the expansion joint used in the bottom slag pipe and the slag inlet pipe of the slag cooler, the lower end of the corrugated pipe is flush with the upper end of the slag inlet pipe, the cavity body formed by the inner slag pipe and the corrugated pipe is communicated with the slag inlet pipe of the slag cooler, so that the dust can be eliminated smoothly when smoke enters the cavity body, accumulation of a large amount of dust can be prevented, and the service life is prolonged to a large extent.
Description
Technical field
The utility model relates to a kind of expansion joint, relates in particular to end slag Guan Yuleng slag machine slag feed pipe joint expansion joint.
Background technique
Because water cooled furnace wall and end slag pipe can expanded by heating, thus all adopt slag pipe of the simple end to insert the mode of cold slag machine slag feed pipe at present, due to joint blow-by, the flue gas in stove and the dust serious environment pollution that easily comes up from gap.
Conventionally everybody adopts general type metal expansion joint to carry out encapsulation process, if notification number is the special expansion joint of a kind of slag discharge pipe of circulating fluidized bed boiler that CN202647740U describes, is provided with movable sealing inner core in it, is divided into movable inner core and lower movable inner core; When type metal expansion joint is stretched, flue gas can enter in the cavity between threaded pipe and movable sealing inner core along the gap between upper movable inner core and lower movable inner core, in cavity, can because being full of dust, cause expansion joint to scrap very soon.
Model utility content
The utility model provides end slag Guan Yuleng slag machine slag feed pipe joint expansion joint, is intended to solve in prior art type metal expansion joint inside and causes short problem in working life because of easy dust stratification.
In order to solve above technical problem; the utility model is achieved through the following technical solutions: comprise the bellows being arranged between end slag Guan Yuleng slag machine slag feed pipe; in described bellows, be provided with and communicate with end slag pipe and for the protection of the interior slag pipe of bellows; the lower end of described bellows is concordant with the upper end of slag feed pipe, and described interior slag pipe communicates with cold slag machine slag feed pipe with the cavity of bellows composition.
Further, also comprise the annular slab that is arranged on bellows upper end-hole, the upper end of described interior slag pipe is connected in annular slab lower surface, and end slag pipe is connected in the upper surface of annular slab; Be provided with annular slab, be convenient to connect.
Further, the end slag seal of tube is welded on the lower surface of annular slab, and the end slag seal of tube is welded on the upper surface of annular slab, and cold slag machine slag feed pipe seal welding is at bellows lower end mouth place; Adopt seal welding, can effectively prevent that flue gas from exposing from joint.
Further, the lower end of described interior slag pipe is suspended in cold slag machine slag feed pipe, can effectively protect bellows, has reduced flue gas and enter the cavity of interior slag pipe and bellows composition.
Further, the size of described interior slag pipe external diameter is 3/4ths of slag feed pipe internal diameter size; Gap in guaranteeing between extension pipe and the slag feed pipe of slag pipe can allow dust discharge smoothly in the inner chamber of bellows, annular slab and interior slag pipe composition.
Compared with prior art the utility model has the advantages that: in the utility model, the lower end of bellows and the upper end of slag feed pipe are concordant, interior slag pipe communicates with cold slag machine slag feed pipe with the cavity of bellows composition, when flue gas enters this cavity, dust can be got rid of smoothly, can not cause the accumulation of dust, obtain significantly working life and improve.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
Consult Fig. 1, end slag Guan Yuleng slag machine slag feed pipe joint expansion joint, comprise the bellows 1 being arranged between end slag pipe 2 and cold slag machine slag feed pipe 3, in described bellows 1, be provided with and communicate with end slag pipe 2 and for the protection of the interior slag pipe 4 of bellows 1, the lower end of described bellows 1 is concordant with the upper end of slag feed pipe 3, and the cavity 6 that described interior slag pipe 4 forms with bellows 1 communicates with cold slag machine slag feed pipe 3; Also comprise the annular slab 5 that is arranged on bellows 1 upper end-hole, the upper end of described interior slag pipe 4 is connected in annular slab 5 lower surfaces, and end slag pipe 2 is connected in the upper surface of annular slab 5; End slag pipe 2 seal weldings are at the lower surface of annular slab 5, and end slag pipe 2 seal weldings are at the upper surface of annular slab 5, and cold slag machine slag feed pipe 3 seal weldings are at bellows 1 lower end mouth place; The lower end of described interior slag pipe 4 is suspended in cold slag machine slag feed pipe 3; The size of described interior slag pipe 4 external diameters is 3/4ths of slag feed pipe 3 internal diameter sizes.
During use, waste material enters from end slag pipe 2, from then entering interior slag pipe 4, finally enters in cold slag machine slag feed pipe 3; In this process, partial fume and dust can enter in cavity 6, and because cavity 6 communicates with cold slag machine slag feed pipe 3, flue gas and dust can be drained in slag feed pipe 3 smoothly, can not cause dust accretion.
The inner chamber lower end of interior slag pipe of the present utility model, bellows and annular slab composition communicates with end slag pipe; when flue gas enters this inner chamber; can not cause the accumulation of dust; can not make flue gas leak; and working life obtain significantly and improve, the lower end of interior slag pipe is suspended in cold slag machine slag feed pipe, has reduced the inner chamber that can effectively reduce flue gas and enter bellows, annular slab and interior slag pipe composition; protect bellows, reduced heat loss.
The foregoing is only specific embodiment of the utility model, but technical characteristics of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification are all encompassed among the scope of the claims of the present utility model.
