Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.Should be understood that embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
On the one hand, the utility model provides a kind of bracket column of coke dry quenching furnace.This bracket column comprises the masonry 1 that is built into by refractory brick, also comprises the protective guard that covers masonry 1.Install protective guard additional by the outside at masonry 1, can effectively improve the antiwear property of bracket column.
With reference to figure 1 and Fig. 2, according to embodiment of the present utility model, protective guard covers the surface in the dry quenched coke oven chute district of being exposed to of masonry 1.These surfaces comprise: the front 11 in the face of the medullary ray of coke dry quenching furnace of masonry 1, and masonry 1 with positive 11 adjacent two sides 13 that roughly are parallel to each other.The surface of these masonries 1 that protective guard covers protrudes from the furnace wall along the radial direction of coke dry quenching furnace, is washed away by high-temperature flue gas and the main region of the frequent change of operating temperature, also is the position of easy breakage of masonry 1.
According to embodiment of the present utility model, protective guard comprises refractory masses 3 and high temperaturesteel flaggy 5.Wherein, the material of refractory masses 3 comprises fire-retardent fiber felt-rug, and the utility model preferably adopts the refractory ceramic fibre felt.According to embodiment of the present utility model, the refractory ceramic fibre felt is compacted to the thickness of 8mm-12mm from the thickness of 15mm-20mm after, paving is on the above-mentioned surface of masonry 1.Should guarantee in the paving technique that the junction between each surface of masonry 1 does not expose.Can use whole refractory ceramic fibre felt directly to carry out paving, also can guarantee to adopt the mode of several refractory ceramic fibre felt overlap joints to carry out paving under the unexposed prerequisite of overlapping part.
After refractory masses 3 pavings are complete, high temperaturesteel flaggy 5 is set in the outside of refractory masses 3.According to embodiment of the present utility model, high temperaturesteel flaggy 5 part that is formed in one can reduce welding like this, guarantees that it has enough intensity.With reference to figure 1, integrated high temperaturesteel flaggy 5 has elasticity, can be clamped in the outside of masonry 1 and refractory masses 3, and fixing refractory masses 3.Simultaneously, the furnace wall also has supporting role to high temperaturesteel flaggy 5.The material of high temperaturesteel flaggy 5 is preferably resistant to elevated temperatures stainless steel plate, and its thickness is preferably 2mm-5mm.By this, provide the protective layer of high-strength heat-resistant on the surface of masonry 1, antiwear property that can Effective Raise bracket column.
Continuation is with reference to figure 1 and Fig. 2.According to embodiment of the present utility model, protective guard also comprises built-in fitting 7.This built-in fitting 7 is embedded in the position that masonry 1 is connected with the furnace wall of coke dry quenching furnace.The part of built-in fitting 7 is embedded in the masonry 1, and another part exposes on masonry 1 surface.Should exposed part weld together with high temperaturesteel flaggy 5, with the mounting block of the high temperature resistant steel plate layer 5 that fixes.The shape of built-in fitting 7 can have multiple choices, such as but not limited to long strip shape or U-shaped.According to embodiment of the present utility model, built-in fitting 7 takes the shape of the letter U, and its bottom is embedded in the masonry 1, and two shanks expose respectively on the surface of two sides of masonry 1 and with high temperaturesteel flaggy 5 and weld together.So, can prevent high temperaturesteel flaggy 5 along the radial direction activity of furnace chamber, cause high velocity air that refractory masses 3 and masonry 1 formed at a high speed washing away thereby avoid crossing from the slit flow between high temperaturesteel flaggy 5 and the refractory masses 3 because of high velocity air.Simultaneously, can also avoid damaging the discharging device for coke that the high temperaturesteel flaggy 5 of disintegration drops in the furnace chamber bottom and cause fault.According to embodiment of the present utility model, in order to strengthen the strength of joint between built-in fitting 7 and the high temperaturesteel flaggy 5, a plurality of built-in fittings 7 be arranged in parallel.In addition, in order to reduce the welding difficulty, according to embodiment of the present utility model, built-in fitting 7 is selected the material identical with high temperaturesteel flaggy 5.
Still with reference to figure 1 and Fig. 2, protective guard also comprises suspender member 9.This suspender member 9 takes the shape of the letter U, opening down top of hanging at masonry 1.Two shanks and the high temperaturesteel flaggy 5 of U-shaped suspender member 9 weld together, in order to prevent that high temperaturesteel flaggy 5 is along the direction activity of the medullary ray that is parallel to coke dry quenching furnace.Suspender member 9 is set avoids equally high velocity air that refractory masses 3 and masonry 1 formed at a high speed washing away, and avoid damaging the discharging device for coke that the high temperaturesteel flaggy 5 of disintegration drops in the furnace chamber bottom and cause fault.According to embodiment of the present utility model, in order to strengthen the strength of joint between suspender member 9 and the high temperaturesteel flaggy 5, a plurality of suspender members 9 be arranged in parallel.In addition, in order to reduce the welding difficulty, according to embodiment of the present utility model, suspender member 9 is selected the material identical with high temperaturesteel flaggy 5.
To sum up, the construction process of bracket column of the present utility model is: utilize die stamping once shaped high temperaturesteel flaggy 5; When building masonry 1 by laying bricks or stones built-in fitting 7 is embedded in the position that is connected with the furnace wall of masonry 1; At the front 11 of building complete masonry 1 by laying bricks or stones and two side 13 paving refractory masses 3; Suspender member 9 is hung top at masonry 1; High temperaturesteel flaggy 5 is set in refractory masses 3 outsides, and shank and the high temperaturesteel flaggy 5 of built-in fitting 7 and suspender member 9 welded together the weld seam full weld.
On the other hand, the utility model also provides a kind of coke dry quenching furnace, and this coke dry quenching furnace has above-mentioned bracket column.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove that in addition each the concrete technical characterictic described in above-mentioned embodiment in reconcilable situation, can make up by any suitable mode.For fear of unnecessary repetition, the utility model is to the no longer separately explanation of various possible array modes.
In addition, also can carry out arbitrary combination between the various embodiment of the present utility model, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
