Abstract
The utility model discloses a movable flue joint sealing structure which comprises a movable smoke expelling rack (1), a groove-shaped socket plate (2), an annular pipe (3), an annular groove (7), a groove sealing heat insulating pad (6), a socket groove (5) and a sealing heat insulating pad (4), wherein the groove-shaped socket plate (2) is fixed on the movable smoke expelling rack (1), the opening end the annular groove (7) is downward and is connected to the outer side of the groove-shaped socket plate (2), the inner part of the annular groove (7) is provided with the hollow and inflatable annular pipe (3), the sealing heat insulating pad (6) is arranged between the annular groove (7) and the annular pipe (3), and the sealing heat insulating pad (4) is arranged in the socket groove (5) of an annular collecting flue joint. The utility model provides a movable flue joint sealing structure with good sealing performance, simple structure and convenient maintenance and overcomes the defects of existing sealing structures.
Description
Technical field
The utility model relates to a kind of movable flue sealing joint structure, particularly the hermetically-sealed construction of a kind of activity of anode-baking furnace smoke evacuation frame and collecting flue interface.
Background technology
The activity smoke evacuation frame of anode-baking furnace is to be used to connect each quirk of anode-baking furnace and the equipment of annular collecting flue, its effect is: utilize the negative pressure in the annular collecting flue, after useless flue gas in each quirk of anode-baking furnace collected by movable smoke evacuation frame, enter in the annular collecting flue, carry out the baking flue gas purified treatment again.The quality of movable smoke evacuation frame and the sealing of annular collecting flue interface is related to what and composition of the exhaust gas volumn of baking flue gas purification; Air be drawn into cigarette wherein after, can reduce flue-gas temperature, dilution flue gas concentration, increase exhaust gas volumn, change system's negative pressure of annular collecting flue and smoke evacuation frame etc., increase the production run expense.
At present, because exhaust gas temperature is higher, the activity smoke evacuation frame of existing anode-baking furnace and the hermetically-sealed construction of annular collecting flue interface mainly contain following two kinds of versions; 1. there is poor sealing performance in socket joint sand seal formula structure, the flimsy shortcoming of sealing gasket, and 2. dull and stereotyped weight is sealed, and the sealing gasket material is an alumina silicate fibre, and sealing effectiveness is also undesirable.
Summary of the invention
The purpose of this utility model is: a kind of good seal performance is provided, and movable flue sealing joint structure simple in structure, easy to maintenance overcomes the defective that has hermetically-sealed construction now.
The utility model is to constitute like this: comprise movable smoke evacuation frame (1), flute profile socket joint plate (2), endless tube (3), annular groove (7), groove sealing heat insulating mattress (6), socket joint groove (5), sealing heat insulating mattress (4); Flute profile socket joint plate (2) is fixed on the movable smoke evacuation frame (1), annular groove (7) openend is downward, and be connected the outside of flute profile socket joint plate (2), place an inflatable endless tube of hollow (3) in the annular groove (7), place groove sealing heat insulating mattress (6) between endless tube (3) and the annular groove (7), sealing heat insulating mattress (4) places the socket joint groove (5) of annular collecting flue interface, and flute profile socket joint plate (2) inserts in the socket joint groove (5) of annular collecting flue interface; Inflatable endless tube (3) is inflated, make its expansion, or inflation in advance, owing to be subjected to from activity smoke evacuation frame (1) weight, make rubber grommet (3) pressurized of inflation, sealing heat insulating mattress (4) and groove that the surface is close in the annular collecting flue socket joint groove (5) seal on the heat insulating mattress (6), form the soft closely sealing surface of one deck, thereby reach the purpose of sealing joint.
The beneficial effects of the utility model are: sealing surface is soft and tight, good seal performance, and sealing is reliable, and is simple in structure, easy to maintenance.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
In Fig. 1, be welded on the movable smoke evacuation frame (1) by flute profile socket joint plate (2), annular groove (7) openend is downward, and be connected the outside of flute profile socket joint plate (2), place an inflatable endless tube of hollow (3) (being similar to bicycle tube) in the annular groove (7), place groove sealing heat insulating mattress (6) between endless tube (3) and the annular groove (7), sealing heat insulating mattress (4) places the socket joint groove (5) of annular collecting flue interface; Groove sealing heat insulating mattress (6) and sealing heat insulating mattress (4) play sealing function and have heat insulating function again, flute profile socket joint plate (2) inserts the socket joint groove (5) of annular collecting flue interface, movable smoke evacuation frame (1) is with after the socket joint groove (5) of annular collecting flue interface is connected, inflatable rubber grommet (3) is inflated, make its expansion, or inflation in advance, because it bears from activity smoke evacuation frame (1) weight, make rubber grommet (3) pressurized of inflation, sealing heat insulating mattress (4) and groove that the surface is close in the annular collecting flue socket joint groove (5) seal on the heat insulating mattress (6), sealing heat insulating mattress (4) and groove sealing heat insulating mattress (6) play sealing function and have heat insulating function again, form the soft closely sealing surface of one deck, thereby reach the purpose of sealing joint.
Claims (2)
1. movable flue sealing joint structure, comprise movable smoke evacuation frame (1), flute profile socket joint plate (2), endless tube (3), annular groove (7), groove sealing heat insulating mattress (6), socket joint groove (5), sealing heat insulating mattress (4) is characterized in that: flute profile socket joint plate (2) is fixed on the movable smoke evacuation frame (1), and annular groove (7) openend is downward, and be connected the outside of flute profile socket joint plate (2), place the endless tube (3) of inflation in the annular groove (7), place groove sealing heat insulating mattress (6) between annular groove (7) and the endless tube (3), sealing heat insulating mattress (4) places the socket joint groove (5) of annular collecting flue interface.
2. movable flue sealing joint structure according to claim 1 is characterized in that: inflation ring (3) pipe is made by the inflatable material of pressurized.
