Description
Technical Field
The utility model relates to a put out stove technical field futilely, especially relate to a put out protection architecture of stove ramp bracket futilely.
Background
The coke dry quenching refers to a coke quenching method for cooling red coke by adopting inert gas. During the coke dry quenching process, red coke is loaded from the top of the coke dry quenching furnace, low-temperature inert gas is blown into a red coke layer of a coke dry quenching cooling chamber by a circulating fan, and after the sensible heat of the red coke is absorbed, the red coke passes through a chute and an annular air duct and is transferred to a boiler area to generate steam.
The dry quenching furnace is divided into a pre-storage area, an annular air duct area, a chute area and a cooling area from top to bottom, the chute area plays a role in bearing the weight of an annular wall in the annular air duct area in the middle of the dry quenching furnace, and the bracket is an important component of the chute area. The dry quenching furnace is not only stressed by the upper masonry, but also scoured by circulating gas and coke powder, and the temperature fluctuation is frequent, so that the refractory bricks at the bracket part can frequently fall off due to damage and fracture, and the bracket part can even collapse to cause the shutdown of the dry quenching furnace in severe cases. Currently, minor and intermediate repairs of the dry quenching furnace are mainly performed around the bracket of the chute area. By changing the material of the bracket brick and improving the structures of the annular air duct area and the inclined duct area, the service life of the bracket is prolonged, and a large part of maintenance cost can be saved.
SUMMERY OF THE UTILITY MODEL
The utility model provides a protection architecture of putting out stove ramp bracket futilely, through the institutional advancement to annular duct district and ramp district combination position, can effectively protect the ramp bracket, alleviate coke and upper portion brickwork to the extrusion stress of bracket, the live time of extension bracket.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a protection structure for a bracket of a chute of a dry quenching furnace comprises a reducing section and a supporting section which are sequentially arranged between an annular air duct area and the chute area from top to bottom; the reducing section is of a conical structure with a large upper opening and a small lower opening, the inner diameter of the top of the reducing section is the same as that of the annular air duct area, the inner diameter of the bottom of the reducing section is the same as that of the supporting section, and the inner diameter of the supporting section is smaller than that of the annular air duct area and that of the top of the chute bracket.
The included angle between the inner surface of the reducing section and the center line of the dry quenching furnace is 15-30 degrees.
The inner diameter of the support section is (50-80) mm of the inner diameter of the bracket of the chute.
The reducing section and the supporting section are built by refractory bricks or precast blocks or cast by castable on site.
The inclined channel bracket is a single inclined channel bracket, a double inclined channel bracket or a multi-inclined channel bracket.
Compared with the prior art, the beneficial effects of the utility model are that:
through the structural improvement to the annular air duct area and the inclined flue area, the bracket of the inclined flue can be effectively protected, the extrusion stress of coke and upper masonry to the bracket is reduced, and the service time of the bracket is prolonged.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
as shown in figure 1, in the conventional dry quenching furnace, the transition section between the annular air duct area 1 and the inclined duct area is a straight section, the inner diameter of the annular air duct area 1 is equal to the inner diameter of the top of the inclined duct bracket 2, the contact area of coke in the dry quenching furnace and the inclined duct bracket 2 is large in the downward moving process, and the inclined duct bracket 2 is easily damaged under the action of long-time strong stress of the coke.
As shown in fig. 2, the protection structure 3 for a bracket of a chute of a dry quenching furnace of the present invention comprises a reducing section 31 and a supporting section 32 sequentially arranged between an annular air duct area 1 and the chute area from top to bottom; the reducing section 31 is of a conical structure with a large upper opening and a small lower opening, the inner diameter of the top of the reducing section 31 is the same as the inner diameter of the annular air duct area 1, the inner diameter of the bottom of the reducing section 31 is the same as the inner diameter of the supporting section 32, and the inner diameter of the supporting section is smaller than the inner diameter of the annular air duct area 1 and the inner diameter of the top of the chute bracket 2.
The included angle between the inner surface of the reducing section 31 and the center line of the dry quenching furnace is 15-30 degrees.
The inner diameter of the support section 32 is (50-80) mm of the inner diameter of the bracket of the chute 2.
The reducing section 31 and the supporting section 32 are made of refractory bricks or precast blocks by masonry, or are cast in situ by casting materials.
The inclined channel bracket 2 is a single inclined channel bracket, a double inclined channel bracket or a multi-inclined channel bracket.
The internal diameter of protection architecture 3 of ramp bracket is less than 2 top internal diameters of ramp bracket, and the coke that falls from the top is guided by the undergauge section and is fallen into below cooling space, and the coke of whereabouts and the contact extrusion and the frictional stress of ramp bracket 2 obviously reduce, are favorable to protecting the bracket and prolong its life.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
