Abstract
The invention provides a heat exchange device on a heating furnace. The heat exchange device on the heating furnace is arranged inside a furnace body and comprises a fan arranged on a furnace roof and further comprises an air inlet, an air outlet, heat exchange pipes and a collecting pipe, wherein the air inlet and the air outlet are arranged in parallel and extend out of the furnace body; the collecting pipe right faces the air inlet and the air outlet; the collecting pipe is of a hollow sealed structure; one half of the heat exchange pipes communicate with the air inlet and the collecting pipe, and the other half of the heat exchange pipes communicate with the air outlet and the collecting pipe; and the heat exchange pipes connected with the air inlet and the air outlet are outwards arched to be in an arc shape from the middle positions, a round guide hole is formed in the middle positions, and the fan is arranged inside the guide hole. The heat exchange device on the heating furnace has the advantages of being simple in structure, ingenious in design, capable of preventing workpieces from oxidizing, uniform in cooling of the interior of a hearth, capable of improving the quality of the workpieces, and the like.
Description
Technical field
The invention 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.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, design ingenious, prevent fall in workpiece oxidation, burner hearth
Temperature heat-exchanger rig uniformly, on the heating furnace of lifting workpieces quality.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that the heat-exchanger rig on a kind of heating furnace,
It is located at furnace interior, and it includes the fan being arranged on furnace roof, its also include air inlet, air outlet,
Heat exchanger tube and collecting pipe, wherein said air inlet is set up in parallel with described air outlet, and described air inlet is with described
Air outlet stretches out outside body of heater, and described collecting pipe is right against described air inlet and air outlet and arranges, described in conflux
Pipe is hollow sealing structure, and described heat exchanger tube has a plurality of, the semi-connected described collecting pipe of one and described air intake
Mouthful, second half connects described collecting pipe and described air outlet, respectively with described air inlet and described air outlet phase
Heat exchanger tube even outwards arches upward curved from intermediate position, and position forms circular pod apertures, institute therebetween
Fan is placed in stating 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.
The present invention uses heat-exchanger rig to cool down burner hearth inside, takes away heat by heat-exchanger rig, simultaneously
By the stirring of stove internal fan, workpiece is lowered the temperature equably, improve the overall quality of workpiece.Can also prevent
Local quickly cools down the impact of material resistance to burner hearth, extends the use side life of burner hearth.And heat exchanger tube blocks sky
Oxygen in gas enters burner hearth, prevents surface of the work from forming oxide-film, reduces being machined to of later stage process
This.
Accompanying drawing explanation
Fig. 1 is the perspective view of the heat-exchanger rig on heating furnace of the present invention.
Structural representation when Fig. 2 is that in Fig. 1, heat-exchanger rig does not has a fan.
Detailed description of the invention
For the technology used in the present invention means and the technique effect that reach being expanded on further, below in conjunction with accompanying drawing
Elaborate with embodiment.
With reference to Fig. 1 and Fig. 2, the heat-exchanger rig on heating furnace of the present invention, its include fan 1, air inlet 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, air inlet 2
Stretch out outside body of heater with air outlet 3.Do not connect mutually between air inlet 2 with air outlet 3 so that the flow direction of air
Single and rapid, do not have sinuous flow, a shunting, simultaneously air inlet 2 or air outlet 3 and blower fan (not shown)
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 3 from air inlet 2 as air
Turn.In one embodiment, heat exchanger tube 4 has 6, wherein 3 connection sides, collecting pipe 5 side and air intake
The same sides of 2,3, mouth connection collecting pipes 5 and air outlet 3.Further, respectively with air inlet 2 and air-out
The heat exchanger tubes 4 that mouth 3 is connected outwards arch upward curved from intermediate position, the conglobate water conservancy diversion of shape therebetween
Hole 6, places fan 1 in pod apertures 6.In another embodiment, heat exchanger tube 4 is vertically installed with two-layer,
Increase the area of dissipation of heat exchanger tube 4 further.
The operation principle of the present invention is: inside heating furnace increase heat-exchanger rig, the air inlet in heat-exchanger rig with
Air outlet is connected with extraneous air, and heat exchanger tube is respectively communicated with collecting pipe and air inlet, air outlet, outside empty
Gas enters heat-exchanger rig from air inlet, is then passed through after heat exchanger tube, collecting pipe, heat exchanger tube again from air outlet
It is discharged to outside body of heater, only the heat of furnace interior is taken out of, and the workpiece in body of heater is not caused oxidation, and
And to workpiece lowering temperature uniform in burner hearth.
Described above the most fully discloses the detailed description of the invention of the present invention.It is pointed out that and be familiar with being somebody's turn to do
Any change that the detailed description of the invention of the present invention is done by the technical staff in field is all without departing from the power of the present invention
The scope of profit claim.Correspondingly, the scope of the claim of the present invention is also not limited only to aforementioned tool
Body embodiment.
