Description

Effective partition device for hanging and tempering blast furnace

Technical Field

The utility model relates to a blast furnace hanging and tempering partition device, belonging to the technical field of blast furnace production equipment.

Background

The blast furnace air supply system of the iron and steel enterprise comprises: the blast furnace tuyere sleeve comprises an air supply surrounding pipe, a hanging system, a blowing pipe, a large sleeve, a middle sleeve and a small sleeve, wherein the inner side of the small sleeve is arranged in the furnace, the outer side of the small sleeve is in contact with the spherical surface of the blowing pipe, and the blowing pipe is required to be detached when the tuyere sleeve is replaced during blast furnace damping down operation, so that the tuyere sleeve can be detached. Blast furnace damping down operation, because the furnace hearth part has residual coal gas, the incident takes place easily during the operation, so open the refluence valve after damping down and take away residual coal gas in the blast furnace, but the refluence suction power is limited, can not take away residual coal gas in the furnace hearth completely, when the workman unloads the wind gap blowpipe, hang and burn after blowpipe junction furnace hearth residual coal gas malleation blowout, the flame is too big, in the past the stokehold worker need wait to flame little after, just can carry out the operation of next change tuyere small cover, the latency is long, seriously influence the maintenance progress, extension blast furnace damping down time is unfavorable for blast furnace fast reblowing production. Therefore, the invention needs to invent an effective partition device for blast furnace hanging tempering, shortens the blast furnace damping down time, and simultaneously eliminates the potential safety hazard of burning and scalding when a tuyere is replaced by a worker.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a device which can effectively cut off and prevent the blast furnace from hanging and tempering, shorten the damping down time of the blast furnace and improve the efficiency; the potential safety hazard that workers are burned and scalded when replacing the air port is eliminated.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is:

the utility model provides a tempering cut-off device is hung to blast furnace, includes asbestos pad, cuts off diaphragm, fixed frame, keep off the fire board, it is octagon to cut off the diaphragm, and three limits constitute and insert the end, and five limits constitute and hang the end, fixed frame, keep off fire board symmetry set up in the end that hangs that cuts off the diaphragm, and the asbestos pad passes through the bolt fastening in one side that cuts off the diaphragm.

The fixed frame and the fire baffle plate are respectively symmetrically provided with a pair of handles.

One side of the hanging end of the partition transverse plate is provided with a striking pad, and the striking pad is a rubber pad and is fixed on the partition transverse plate through a bolt.

The fixed frame is in an inverted L shape, the height of the fixed frame is 20-40 mm, and the width of the upper edge of the fixed frame is 20-40 mm.

The thickness of the asbestos pad is 5-15 mm.

The center of the asbestos pad and the partition transverse plate is provided with an observation hole with the diameter of 150 plus 250 mm.

The fire baffle plate is 150 mm high and 300 mm long.

The partition transverse plates are steel plates with the thickness of 1-3 mm.

The utility model has the advantages that:

the device has the advantages of simple structure and convenient operation, can effectively isolate and suspend tempering, and greatly reduces the waiting time when the tuyere of the blast furnace is replaced.

labeled as: partition diaphragm 1, fixed frame 2, keep off hot plate 3, handle 4, strike pad 5, bolt 6, asbestos pad 7, observation hole 8.

Detailed Description

The embodiments of the present invention are described below with reference to the accompanying drawings:

asbestos with the thickness of 5mm is taken, a hole with the diameter of 220mm is formed in the center of the asbestos, and the asbestos is cut into an octagonal asbestos pad 7 with the shape and the size consistent with the cross section of a blast furnace hanger. Selecting a steel plate with the thickness of 2 mm, cutting the steel plate into an octagonal partition transverse plate 1 with the shape and the size consistent with those of a blast furnace hanger, tiling an asbestos pad 7 and fastening the asbestos pad on the partition transverse plate 1 by using bolts. The inverted L-shaped fixed frame 2 is made of a steel plate, the height is 30 mm, and the width of the upper edge is 25 mm. The fixed frame 2 is vertically welded on the partition transverse plate 7, and the fire baffles 3 with the height of 120mm and the length of 260mm are respectively welded on the two sides of the fixed frame 2. The rubber pad is fixed at the tail part of the fixed frame 2 by using bolts to form the striking pad 5. A pair of handles 4 are symmetrically welded on the side surfaces of the fixed frame 2 and the fire baffle plate 3 respectively.

After the blast furnace stops blowing, the insertion end of the partition transverse plate 1 is inserted into the lower edge of the hanger by moving the handle 4, and the striking pad 5 is struck by a sledge hammer, so that the fixed frame 2 on the suspension end of the partition transverse plate 1 is fully matched with the hanger. The inside of the hanger can be seen through the observation hole 8. When observing, the fire baffle 3 can effectively block the baking of flame.

The device has simple structure and convenient operation, and the waiting time for replacing the tuyere of the blast furnace by using the device can be shortened to 3 minutes from about 30 minutes before, thereby effectively reducing the damping down time of the blast furnace and being beneficial to the quick reblowing of the blast furnace to achieve the yield; meanwhile, the hanging part is effectively sealed, so that the occurrence of burn accidents caused by external fire is reduced.
