Description
Technical field
This utility model belongs to heating furnace field, the heat-exchanger rig on a kind of heating furnace.
Background technology
In prior art, normalizing/annealing furnace use blower fan directly blow into inside burner hearth by extraneous air, to work
Part carries out direct contact cooling, it is done so that shortcoming be that the oxygen in extraneous air also can be brought into together
Come, and in the case of furnace high-temperature, easily surface of the work is aoxidized, form layer oxide film.Cause
Workpiece processes the decline of quality, adds material and the machining cost of later stage removal surface oxide layer simultaneously.
The blower fan blow-through type of cooling can cause the inhomogeneous cooling of workpiece even simultaneously, directly reduces one-piece machine member quality.
Utility model content
The purpose of this utility model be to provide a kind of simple in construction, design ingenious, prevent workpiece oxidation, burner hearth
Interior lowering temperature uniform, lifting workpieces quality heating furnace on heat-exchanger rig.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that the heat exchange dress on a kind of heating furnace
Putting, it is located at furnace interior, and it includes the fan being arranged on furnace roof, and it also includes air inlet, air-out
Mouthful, heat exchanger tube and collecting pipe, wherein said air inlet is set up in parallel with described air outlet, described air inlet and
Described air outlet stretches out outside body of heater, and described collecting pipe is right against described air inlet and arranges with air outlet, described
Collecting pipe is hollow sealing structure, and described heat exchanger tube has a plurality of, and the semi-connected described collecting pipe of one is with described
Air inlet, second half connects described collecting pipe and described air outlet, respectively with described air inlet and described air-out
The heat exchanger tube that mouth is connected outwards arches upward curved from intermediate position, and position forms circular pod apertures therebetween,
Fan is placed in described pod apertures.
Further, do not connect mutually between described air inlet and air outlet.
Further, described heat exchanger tube is vertically installed with one or more layers.
Further, described collecting pipe is rectangular shape, and its side, side is connected with described heat exchanger tube.
This utility model uses heat-exchanger rig to cool down burner hearth inside, takes away heat by heat-exchanger rig,
By the stirring of stove internal fan, workpiece is lowered the temperature equably simultaneously, improve the overall quality of workpiece.Can also
Prevent local from quickly cooling down the impact of material resistance to burner hearth, extend the use side life of burner hearth.And heat exchanger tube hinders
Oxygen in air absolutely enters burner hearth, prevents surface of the work from forming oxide-film, and the machine reducing later stage process adds
Work cost.
Accompanying drawing explanation
Fig. 1 is the perspective view of the heat-exchanger rig on this utility model heating furnace.
Structural representation when Fig. 2 is that in Fig. 1, heat-exchanger rig does not has a fan.
Detailed description of the invention
By technological means that this utility model used and the technique effect that reach are expanded on further, below in conjunction with
Drawings and Examples elaborate.
With reference to Fig. 1 and Fig. 2, the heat-exchanger rig on this utility model heating furnace, it includes fan 1, air intake
Mouth 2, air outlet 3, heat exchanger tube 4 and collecting pipe 5.Wherein air inlet 2 is set up in parallel with air outlet 3, enters
Air port 2 and air outlet 3 stretch out outside body of heater.Do not connect mutually between air inlet 2 with air outlet 3 so that air
Flow to single and rapid, do not have sinuous flow, a shunting, air inlet 2 or air outlet 3 are with blower fan (not simultaneously
Illustrate) it is connected so that air flowing is more rapid.Collecting pipe 5 is right against air inlet 2 and arranges with air outlet 3,
Collecting pipe 5 is the rectangular shape of hollow sealing, and collecting pipe 5 flows to air outlet as air from air inlet 2
The transfer of 3.In one embodiment, heat exchanger tube 4 has 6, wherein 3 connection sides, collecting pipe 5 side
With air inlet 2, the same side of 3 connection collecting pipes 5 and air outlet 3.Further, respectively with air inlet 2
The heat exchanger tube 4 being connected with air outlet 3 outwards arches upward curved from intermediate position, forms circle therebetween
Pod apertures 6, place fan 1 in pod apertures 6.In another embodiment, heat exchanger tube 4 is vertically installed with
Two-layer, increases the area of dissipation of heat exchanger tube 4 further.
Operation principle of the present utility model is: inside heating furnace increases heat-exchanger rig, the air intake in heat-exchanger rig
Mouth is connected with extraneous air with air outlet, and heat exchanger tube is respectively communicated with collecting pipe and air inlet, air outlet, outward
Portion's air enters heat-exchanger rig from air inlet, again from going out after being then passed through heat exchanger tube, collecting pipe, heat exchanger tube
Air port is discharged to outside body of heater, is only taken out of by the heat of furnace interior, and the workpiece in body of heater does not cause oxidation,
And to workpiece lowering temperature uniform in burner hearth.
Described above the most fully discloses detailed description of the invention of the present utility model.It is pointed out that ripe
Know any change that detailed description of the invention of the present utility model done by person skilled in art all without departing from this
The scope of claims of utility model.Correspondingly, the scope of claim of the present utility model is the most not
It is limited only to previous embodiment.
