Abstract
The utility model discloses an external connecting bend of small -size hot -blast furnace, including major part and microcephaly, pass through welded connection between major part and the microcephaly, the welding of capitular bottom has square flange, square flange and furnace cooperation, the bottom welding of major part has rectangle flange, rectangle flange and heat exchanger cooperation, the microcephaly is convex structure, the last strengthening rib that is equipped with of microcephaly. The utility model discloses an external connecting bend of small -size hot -blast furnace, the elbow is external, has saved built -in conical head structure, reduces the whole length of hot -blast furnace, has increased the headspace of heat exchanger, deashing, dismantlement, easy maintenance, the microcephaly is convex structure, and messenger's air is quicker in the circulation of heat exchanger joint department.
Description
Technical field
The utility model relates to hot-blast stove technical field, particularly relates to the external connecting bend of a kind of small-sized air heating furnace.
Background technology
The burner hearth of hot-blast stove connects heat exchanger by elbow, elbow between current connection burner hearth and heat exchanger is 90 ° of rounded bend, the mode that the two ends of elbow are all passed through to weld coordinates with other parts, make the length of hot-blast stove entirety longer like this, reduce the headspace of heat exchanger, and service life is shorter.
Utility model content
The purpose of this utility model there is provided the external connecting bend of a kind of small-sized air heating furnace, elbow is external, eliminate built-in conehead structure, reduce hot-blast stove entire length, increase the headspace of heat exchanger, deashing, dismounting, easy to maintenance, described microcephaly is arc-shaped structure, makes air quicker in the circulation at heat exchanger joint place.
The technical solution adopted in the utility model is as follows:
The external connecting bend of a kind of small-sized air heating furnace, comprise major part and microcephaly, by being welded to connect between described major part and microcephaly, the bottom welding of described microcephaly has square adpting flange, square adpting flange coordinates with burner hearth, and the bottom welding of described major part has rectangle adpting flange, and rectangle adpting flange coordinates with heat exchanger, described microcephaly is arc-shaped structure, and microcephaly is provided with reinforcement.
Flame retardant coating has all been built in described major part and microcephaly inside.
Compared with the prior art, the beneficial effects of the utility model are as follows:
The external connecting bend of small-sized air heating furnace of the present utility model, elbow is external, eliminate built-in conehead structure, reduce hot-blast stove entire length, increase the headspace of heat exchanger, deashing, dismounting, easy to maintenance, described microcephaly is arc-shaped structure, make the circulation of air at heat exchanger joint place more quick, flame retardant coating has all been built in described major part and microcephaly inside, improves the service life of elbow.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model will be further described.
See accompanying drawing, the external connecting bend of a kind of small-sized air heating furnace, comprise major part 1 and microcephaly 2, by being welded to connect between described major part 1 and microcephaly 2, the bottom welding of described microcephaly 2 has square adpting flange 3, square adpting flange 3 coordinates with burner hearth, the bottom welding of described major part 1 has rectangle adpting flange 4, and rectangle adpting flange 4 coordinates with heat exchanger, and described microcephaly 2 is arc-shaped structure, microcephaly 2 is provided with reinforcement 5, and flame retardant coating has all been built in described major part and microcephaly inside.The external connecting bend of small-sized air heating furnace of the present utility model, elbow is external, eliminate built-in conehead structure, reduce hot-blast stove entire length, increase the headspace of heat exchanger, deashing, dismounting, easy to maintenance, described microcephaly is arc-shaped structure, make the circulation of air at heat exchanger joint place more quick, flame retardant coating has all been built in described major part and microcephaly inside, improves the service life of elbow.
