Description

Galvanizing iron wire annealing furnace

Technical field

The utility model belongs to change ferrous metal physical structure group, i.e. C21D, particularly wire anneling production line on International Patent Classification (IPC).

Background technology

Wire particularly iron wire need be zinc-plated for corrosion protection, and its former process is annealing, to increase toughness.Annealing furnace has well formula, bell-jar, also has tunnel like.The former belongs to batch production, and efficient is not high.The latter has realized continuous production.Chinese patent 02269892.2 has proposed intelligent control wire annealing device, has announced the scheme that wire is heat-treated by the stainless steel tube that protective atmosphere is arranged, and the intelligent control that focuses on putting silk and receive silk is not open to the integral body of annealing device.Chinese patent 00205096.X then discloses the multi-chamber continuous annealing furnace scheme.But boiler tube is owing to expanding with heat and contract with cold the production dimensional change, and the mobile splicing between the furnace chamber is not all made contributions.

The utility model content

The purpose of this utility model is to provide a kind of galvanizing iron wire annealing furnace, and it can quick travel also be regulated, splice, and realizes continuous high-efficient production.For expanding with heat and contract with cold of boiler tube setting device has been arranged, overcome dimensional change and the technical barrier that brings.

It is as follows to disclose new technical scheme:

A kind of galvanizing iron wire annealing furnace has boiler tube at least, it is characterized in that this stove is spliced by 2-10 unit, and bell, furnace side plate and furnace bottom and inboard thermal insulation layer thereof surround burner hearth:

The burner hearth left end has opening for feed and charging to seal up a door;

The burner hearth right-hand member has discharge port and discharging to seal up a door;

Boiler tube runs through opening for feed and discharge port;

There is heating unit the below of boiler tube;

Be fixed with the feed combinations frame on the opening for feed, on pulley is arranged, the plumb line that hangs with weight links to each other with boiler tube by pulley;

There are two pack supports each unit, and there are setting device and castor in its lower end.

Press such scheme, because there is support each unit, but therefore quick travel is regulated height, realizes splicing; The plumb line of feed combinations frame links to each other with boiler tube, by pulley, weight the flexible of boiler tube is regulated automatically.But this annealing furnace continuous high-efficient operation has also overcome a plurality of difficult problems of prior art.

Description of drawings

Fig. 1 is the utility model overall schematic, and unit omits in the middle of it.

Fig. 2 is the A-A sectional view of Fig. 1.

Wherein: 1, feed combinations frame 1-1, weight 1-2, plumb line 1-3, pulley 2, boiler tube 3, opening for feed 4, charging seal up a door 5, bell 6, furnace side plate 7, discharging seal up a door 8, discharge port 9, support 10, setting device 11, castor 12, protective tube group 13, ceramic fiber cotton 14, heating unit 15, furnace bottom.

Embodiment

A kind of galvanizing iron wire annealing furnace has boiler tube 2 at least, it is characterized in that this stove is spliced by 2-10 unit, and bell 5, furnace side plate 6 and furnace bottom 15 and inboard thermal insulation layer thereof surround burner hearth:

The burner hearth left end has opening for feed 3 and charging to seal up a door 4;

The burner hearth right-hand member has discharge port 8 and discharging to seal up a door 7;

Boiler tube 2 runs through opening for feed 3 and discharge port 8;

There is heating unit 14 below of boiler tube 2;

Be fixed with feed combinations frame 1 on the opening for feed 3, on pulley 1-3 is arranged, the plumb line 1-2 that hangs with weight 1-1 links to each other with boiler tube 2 by pulley 1-3;

There are two pack supports 9 each unit, and there are setting device 10 and castor 11 in its lower end.

The thermal insulation layer of bell 5 inboards is mainly folding pyroceram fibre cotton 13, forms rack by protective tube group 12 and fixes.

Boiler tube 2 props up for 2-36 side by side.

Thermal insulation layer has woven asbesto, refractory brick, insulating brick, pyroceram fibre cotton or plate usually.Bell 5 inboards upwards are fixed with asbestos plate, pyroceram fibre cotton 13 folding fillings successively, catch protection with protective tube group 12.The inboard of furnace bottom 15 upwards is fixed with asbestos plate, refractory brick, insulating brick successively.For preventing boiler tube 2 displacement up and down, therefore rest in the tube seat of putting brick that is provided with at interval.Put brick on insulating brick.Electric heating device 14 is being put between the brick.

Iron wire passes through in boiler tube 2, is filled with protection gas routinely, nitrogen, hydrogen that this example adopts ammonia to decompose.Setting device 10 as long as offer the challenge, can be expected lifting and fixed scheme, for example: copy the refrigerator pin.

Production line length of the present utility model can be according to the technology adjustment, and this example adopts 10 unit, and length reaches 24m, width 2.9m, 36 in boiler tube.So scale is that prior art can not realize.
