A kind of Novel backfire stove thermocirculator
Technical field
This utility model relates to Field of Heat-treatment, particularly relates to a kind of Novel backfire stove thermocirculator.
Background technology
In stove, heated air circulation device is directly connected to the uniformity of in-furnace temperature and the quality of heat treated part, currently used hot blast
In circulating device has defect in various degree, mainly stove, hot air apparatus is unreasonable, lacks order cycle, causes heat treatment work
Part is heated uneven, and unstable with a batch of workpiece processing quality, blower fan poor work stability, in heated air circulation device
When motor is maintained, dismantlement work is loaded down with trivial details, can not meet the requirement of heat treatment.
Chinese utility model patent: for the air duct type heated-air circulation device of tempering furnace, patent No. application number: 201020581096.2,
Disclose a kind of air duct type heated-air circulation device, it is possible to make metal material in tempering furnace, heat treatment process be heated evenly, rationally,
Fully, effectively make use of the heat treatment space in stove and heat energy.But the blower fan structure of this air duct type heated-air circulation device is more
Complexity, vibration is big, and poor work stability, noise is the biggest.And the resistor in body of heater needs often to change, because resistor is complete
Entirely it is arranged on furnace interior, needs whole motor to remove during replacing, change trouble.
Utility model content
For problem above, this utility model devises a kind of Novel backfire stove thermocirculator, to solve existing tempering furnace thermal cycle
Device also exists blower fan and shakes big, poor work stability, and troublesome problem is changed in maintenance.
The technical solution of the utility model is: this assembling is in body of heater upper end, and blower fan includes motor, fan seat, bearing and wind
Leaf, fan seat is connected with motor, and bearing lower end connects fan blade, and fan blade is located in body of heater;Body of heater includes stove outer covering, guipure, spoke
Penetrating pipe and wind deflector, guipure lower end is provided with guipure bracket, and stove outer covering is provided with radial canal jack, and radial canal passes through radial canal jack
Insert in body of heater.
As preferably, the quantity of radial canal is two, is respectively arranged on body of heater both sides, and the radial canal efficiency of heating surface is high, uses more steady
Fixed.
As preferably, being provided with air channel between guipure and radial canal, air channel makes heat be circulated.
As preferably, stove outer covering is provided with heat-insulation layer, and heat-insulation layer can reduce heat and scatter and disappear.
The beneficial effects of the utility model are: this utility model blower fan is high-temperature long-shaft fan, have vibration little, working stability,
The feature that noise is little, makes the wind circulation in air channel more uniform;Secondly detachable radial canal substitutional resistance band, radiation are used
Pipe is directly inserted in body of heater, keeps in repair and change more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of blower fan of the present utility model.
Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1-2: this blower fan 1 is installed on body of heater 1A upper end, blower fan 1 includes motor 8, fan seat 10, bearing 9 and
Fan blade 11, motor 8 is arranged on body of heater 1A upper end by fan seat 10 by motor 8, and bearing 9 lower end connects fan blade 11, fan blade
11 are located in body of heater 1A.
Body of heater 1A includes that stove outer covering 2, guipure 5, radial canal 4 and wind deflector 7, guipure 5 lower end are provided with guipure bracket 6, outside stove
Shell 2 is provided with radial canal jack, and radial canal 4 is inserted in body of heater 1A by radial canal jack.
The quantity of radial canal 4 is two, is respectively arranged on body of heater 1A both sides, and radial canal 4 efficiency of heating surface is high, uses more stable.
Being provided with air channel 5A, air channel 5A between guipure 5 and radial canal 4 makes heat be circulated.
Stove outer covering 2 is provided with heat-insulation layer 3, and heat-insulation layer 3 can reduce heat and scatter and disappear.
Tempering furnace operationally, starts blower fan 1, and the fan blade 11 of extension set 1 lower end starts to rotate, two radial canals 4 in body of heater
The air around heat produced, the hot blast that the fan blade 11 of rotation promotes the air of heating and formed starts along three-back-shaped wind
Road order cycle.
When radial canal 4 changed by needs, only be replaced after radial canal need to be extracted, easy to operate.
The above is only preferred implementation of the present utility model, for those skilled in the art, not
On the premise of departing from this utility model principle, it is also possible to making some improvement, these improvement also should be regarded as protection of the present utility model
Scope.
