In addition; It is terminal that part between wedge wedging big arch of kiln and the bearing has a wedge; The height of this wedge end is identical with the height of the bearing boss facade that is contacted; Promptly when the space between wedge wedging big arch of kiln and the bearing, can fit like a glove, guarantee that further hot flue gas can not flow out.
Consider that from the angle of structural stability this wedge end is usually located at the inboard of the bearing bottom surface center line of bearing bottom surface, promptly more inboard near the furnace wall.
For the ease of the length according to timely adjustment of the expanded by heating of kiln and the contacted adjusting screw(rod) of wedge, the column of install adjustment screw rod is detachable steel frame construction.This structure can adapt to the big arch of kiln because of the different expansions that produce of heating temperature, through the length of adjustment column adjusted screw rod, and makes the arch top of kiln become the firm arch top of a kind of safety.
In order to guarantee the uniformity of big arch of kiln and bearing expanded by heating, big arch of kiln and bearing adopt the refractory material of same-type to process.Further, big arch of wedge and kiln and bearing also adopt the refractory material of same-type to process.
The beneficial effect of the utility model is:
(1) the big arch of the kiln of the utility model is an arc-shaped structure, and bearing is that a front is the plane, and the back is the structure of circular arc, and the circular arc of this circular arc and the big arch of kiln just in time coincides together, and the refractory material of big arch of kiln and bearing employing same-type.Guaranteed the uniformity of big arch of kiln and bearing expanded by heating like this, hot flue gas can not be flowed out.
(2) wedge that adopts of the utility model is the parts that just in time can fix the space between big arch of kiln and the bearing, and simultaneously, wedge is provided with column at the back, and column is provided with the screw rod that can adjust length, and the screw rod front overlaps with wedge at the back.When the big arch of kiln produces expansion because of being heated,, can make the arch top of kiln can access effective fixing like this, become the firm arch of a kind of safety and push up through the length of adjustment column screw rod.
(3) in the kiln arch roof construction of the utility model, install owing to employing between arch top and the bearing is similar to modular mode, and fix, be convenient to maintenance (can dismantle or change) disparate modules to whole kiln through wedge.Simultaneously, big arch structure can be maked somebody a mere figurehead on column, and such structure is convenient to cold repair at the bottom of pool wall, the pond, and the big arch of needn't dismantling again can reduce input.
(4) the kiln arch roof construction of the utility model has very strong adaptability, can be widely used in above the different kilns.
