As shown in Figure 1, water-cooled non-metal expansion joint of the present utility model comprises water cooled furnace wall 100, goes up metal framework 200, metal framework 300, live metal frame 400, two sections pouring material 500, collet 600, telescopic cover 700 and dust rings 800 down.
Wherein water cooled furnace wall 100 by bend to "
" the carbon steel path seamless steel pipe 101 of shape is around forming; weld by fin between the carbon steel path seamless steel pipe 101; make water cooled furnace wall 100 have first cylindrical wall 102 and be positioned at the first ring-like end plate 103 in the outside, first cylindrical wall, 102 upper ends; first ring-like end plate 103 outer edges also have the ring-like outer wall 104 of downward extension; and at the two ends of water cooled furnace wall 100, promptly the lower end of the lower end of first cylindrical wall 102 and ring-like outer wall 104 is connected with the header tank 105,106 of the ring-type that is communicated with each carbon steel path seamless steel pipe 101.By these two header tanks 105,106, can in each carbon steel path seamless steel pipe 101, lead to cooling water.
The top that is positioned at water cooled furnace wall 100 of following metal framework 300, its axial symmetrical half section be "
" shape; integral body is flat-shaped; have circular radial ring flat-plate 301, be connected in circular radial end plate 301 outer edges on cylinder plate 302 in succession, be connected in and connect radially connecting Circular Plate 303 and being connected the rectangular shape connecting ring 304 that radially connects Circular Plate 303 inside edges of cylinder plate 303 lower ends.This time metal framework 300 is welded on the water cooled furnace wall 100, concrete welding manner is: rectangular shape connecting ring 304 is welded on the ring-like outer wall 104 of water cooled furnace wall 100, thereby forms radially interlayer 902 between the first ring-like end plate 103 of the circular radial ring flat-plate 301 of feasible metal framework 300 down and water cooled furnace wall 100.
The axial symmetrical half section of live metal frame 400 be "
" shape, tricyclic end plate 402, the three cylindrical walls 401 that have the 3rd cylindrical wall 401 and be connected the 3rd cylindrical wall 401 lower ends outsides insert in the axial interlayer 901, and this tricyclic end plate 402 inserts radially in the interlayer 902.So, be encircled into ring-like frame space 900 by last metal framework 200, following metal framework 300 and live metal frame 400.The collet 600 that ceramic fiber blanket is made just is filled in this frame space 900, particularly, this collet 600 is divided into inside and outside two-part and fills, wherein, inner collet is fixed on metal framework 200 and the following live metal frame 400 by bitch, and the external insulation cover is enclosed within on the inner collet again.And telescopic cover 700 adopts composite material to make; has certain elasticity; then outer wrapping on the collet 600, its upper and lower end is connected with the outer edge of last metal framework 200 and following metal framework 300 respectively, thus air flue protection collet 600 and the effect that prevents collet 600 landings.In order further to protect telescopic cover 700, the telescopic cover 700 outer mobile plates 903 that also are with.
Two sections pouring materials 500 are separately fixed at the inboard of first cylindrical wall 102 of the inboard of second cylindrical wall 201 of metal framework 200 and water cooled furnace wall 100, and the lower end surface that is positioned at that section pouring material of first cylindrical wall, 102 inboards has the inclined-plane that cooperatively interacts.Particularly, the epimere pouring material is fixed on the inboard of second cylindrical wall 201 of metal framework 200 with bitch, the hypomere pouring material is fixed on the inboard of first cylindrical wall 102 of water cooled furnace wall 100 when then by the user stove smoke pipe road being installed at the scene.800 of the dust rings that ceramic fiber blanket is made are installed between the two ends pouring material 500, be corresponding live metal frame 400 positions, be used for the 3rd cylindrical wall 401 and the slit of axial interlayer 901 and the slit of tricyclic end plate 402 and axial interlayer 902 of shutoff live metal frame 400, prevent that the High Temperature Furnaces cigarette from entering nonmetallic collet 600 of damage and telescopic cover 700 in the frame space 900 from this two slit.In order to prevent dust ring 800 landings, the inclined-plane that the lower end surface of the upper-end surface of this dust ring 800 and upper end pouring material is designed to cooperatively interact.
It more than is exactly water-cooled non-metal expansion joint of the present utility model, wherein the 3rd cylindrical wall 401 of live metal frame 400 and tricyclic end plate 402 can be at axial interlayers 901 and are radially moved in the motion in the interlayer 902, thereby can effectively absorb the three direction displacement in stove smoke pipe road, thereby avoid the distortion in stove smoke pipe road impaired.Two sections pouring material 500 can play wear-resisting heat-blocking action, the protection non-metal expansion joint.Collet 600 can play the heat-insulation and heat-preservation effect to the stove cigarette of the non-metal expansion joint of flowing through, and reduces the heat loss of stove cigarette.And the frame space 900 that is encircled into by last metal framework 200, following metal framework 300 and live metal frame 400 can be fixed on collet 600 well, prevents coming off of collet 600.Because the tricyclic end plate 402 of live metal frame 400 and the heat that axially slit enters between the interlayer are many; damage the nonmetallic material of frame space 900 easily; can effectively reduce this part heating temperature by being connected with cooling water in the water cooled furnace wall 100; thereby more effectively protect nonmetallic material, make the life-span of non-metal expansion joint improve greatly.
In sum, the utility model water-cooled non-metal expansion joint have can effectively absorb stove smoke pipe road three direction displacement and can guarantee to absorb three direction displacement after the advantage that still can work reliably and with long-term of inner wearing-proof refractory material and collet.
But; those skilled in the art will recognize that; above-mentioned embodiment is exemplary; be in order better to make those skilled in the art can understand this patent; can not be interpreted as it is restriction to this patent protection domain; so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.
