Abstract
The invention relates to an expansion joint, in particular to an expansion joint used at the connecting position of a bottom slag tube and a slag cooler slag inlet tube in order to solve the problem that in the prior art, because dust is accumulated in a metal expansion joint easily, the service life of the metal expansion joint is short. The bottom slag tube and the slag cooler slag inlet tube are connected through the expansion joint, the expansion joint comprises a corrugated pipe arranged between the bottom slag tube and the slag cooler slag inlet tube, an inner slag tube communicated with the bottom slag tube and used for protecting the corrugated tube is arranged in the corrugated tube, the lower end of the corrugated tube is flush with the upper end of the slag inlet tube, and a cavity formed by the inner slag tube and the corrugated tube is communicated with the slag cooler slag inlet tube. According to the expansion joint, the lower end of the corrugated tube is flush with the upper end of the slag inlet tube, the cavity formed by the inner slag tube and the corrugated tube is communicated with the slag cooler slag inlet tube, when smoke enters the cavity, dust can be smoothly discharged out, the dust can not be accumulated, and the service life of the expansion joint is prolonged to a large extent.
Description
Technical field
The present invention relates to a kind of expansion joint, relate 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-purpose 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.
Summary of the invention
The invention provides end slag Guan Yuleng slag machine slag feed pipe joint expansion joint, be intended to solve in prior art that type metal expansion joint is inner causes short problem in working life because of easy dust stratification.
In order to solve above technical problem; the present invention 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 that bellows forms.
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 has entered the cavity that interior slag pipe and bellows form.
Further, the size of described interior slag pipe external diameter is 3/4ths of slag feed pipe internal diameter size; In the inner chamber that in guaranteeing, the extension pipe of slag pipe and the gap between slag feed pipe can allow dust form from bellows, annular slab and interior slag pipe, discharge smoothly.
Compared with prior art advantage of the present invention is: in the present invention, 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 that bellows forms, 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 invention will be further described:
Fig. 1 is structural representation of the present invention.
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 described interior slag pipe 4 communicates with cold slag machine slag feed pipe 3 with the cavity 6 that bellows 1 forms; 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 that interior slag pipe of the present invention, bellows and annular slab form 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 acquisition in working life raising significantly, the lower end of interior slag pipe is suspended in cold slag machine slag feed pipe, has reduced and can effectively reduce the inner chamber that flue gas enters bellows, annular slab and interior slag pipe composition; protect bellows, reduced heat loss.
The foregoing is only specific embodiments of the invention, but technical characteristics of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and the variation of doing or modification are all encompassed among the scope of the claims of the present invention.
