Abstract
The utility model relates to the field of coke dry quenching devices, in particular to a dry quenching chamber adopting an air-cooling chute technology, which comprises a cooling chamber, an inclined flue, a circular air duct and a pre-storing chamber, and is characterized in that the inside of the partition wall of the inclined flue is provided with a cooling device and the outside thereof is provided with refractory bricks. The cooling device adopts a metal structure; and a zigzag air channel is arranged in the cooling device, and the air channel is connected with an external air pipeline through a branch pipe. The upper part of the cooling device is provided with a refractory brick support plate, and refractory materials at the upper part and the lower part of the refractory brick support plate are divided into two parts. The dry quenching chamber adopting the air-cooling chute technology has the advantages that the structure can prolong the service life of the partition wall of the chute of the dry quenching chamber, simultaneously simplifies the repairing method of the partition wall of the chute of the dry quenching chamber, shortens the repairing cycle, and reduces the investment of an air lead-in and cooling air returning system.
Description
Technical field
The utility model relates to the dry coke quenching auxiliary field, particularly a kind of dried stove that puts out that adopts air cooling slant flue technique.
Background technology
In the prior art, the dried partition wall that puts out between the oblique flue of stove is to put out the structure of encorbelmenting in the stove center to dried, and the chute partition wall all is firebrick structure, and the weight of chute partition wall top refractory brick and the downward frictional force of coke all focus on the chute partition wall; In addition, to expand or shrink when being subjected to cold and hot variation owing to the chute partition wall.Owing to above two reasons, the chute partition wall cracks easily, ruptures when ordinary production is operated, and at dried repair time that stove do not reach regulation shutdown maintenance of just having to that puts out, greatly reduces dried work-ing life of putting out stove.In addition, in the prior art, the dried stove that puts out generally adopts by peephole and imports air and reflux gas to annular passage, and this just need be provided with two and overlap independently tubing system, and the pipeline of reflux gas is long, invests many accordingly.
Summary of the invention
The purpose of this utility model is to provide a kind of dried stove that puts out that adopts air cooling slant flue technique, this technology can prolong dried work-ing life of putting out stove chute partition wall, simplified the dried method for maintaining that puts out stove chute partition wall simultaneously, shorten maintenance cycle, reduced the investment of air importing and cooling gas return-flow system.
For achieving the above object, the utility model is realized with following technical scheme:
A kind of dried stove that puts out that adopts air cooling slant flue technique comprises cooling room, oblique flue, annular passage, the chamber that prestores, and it is characterized in that tiltedly mid-feather inside is refrigerating unit, and the outside is a refractory brick.
Described refrigerating unit adopts metal construction.
Be provided with full of twists and turns gas passage in the described refrigerating unit, this gas passage is connected by the gas pipeline of arm with the outside.
Described arm is provided with the air volume regulating valve door.
Described refrigerating unit is provided with thermometer hole.
Described refrigerating unit top is provided with brick plate, and the refractory materials of brick plate upper and lower part is divided into two parts.
Compared with prior art, the utility model has the advantages that:
1) because inner refrigerating unit, the outside structure that adopts refractory brick of adopting of oblique mid-feather, and in refrigerating unit, be provided with full of twists and turns gas passage and carry out air cooling, the heat of refrigerating unit is passed in absorption by coke, thereby refrigerating unit is shielded, and the too high refrigerating unit that causes of prevention Yin Wendu damages;
2) owing to be provided with brick plate, make the refractory materials of brick plate upper and lower part be divided into two parts, thereby make the expansion of top refractory brick not influence bottom refractory brick, two portions refractory materials is divided into two integral body about making, and has prevented that two portions refractory brick makes the drawing crack of chute partition wall because of swell increment is inconsistent up and down;
3) this structure can prolong dried work-ing life of putting out stove chute partition wall, has simplified the dried method for maintaining that puts out stove chute partition wall simultaneously, has shortened maintenance cycle, has reduced the investment of air importing and cooling gas return-flow system.
