Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that, accompanying drawing all adopts the form that simplifies very much and all uses non-ratio accurately, only in order to object that is convenient, aid illustration the utility model embodiment lucidly.
As shown in Figure 1, the utility model provides a kind of resistance furnace, and the furnace chamber 20 comprising body of heater 10 and be arranged in described body of heater 10, described furnace chamber 20 comprises center furnace chamber 21 and is looped around the periphery furnace chamber 22 around described center furnace chamber 21.Wherein the material of body of heater 10 is heat-barrier material, and the temperature of furnace chamber 20 and stove external environment are completely cut off.Heat-barrier material from inside to outside form positive thermograde in the radial direction, the utility model is on this thermograde direction, outputs new furnace chamber 20.
Preferably, the quantity of described periphery furnace chamber 22 has multiple, each other equidistant arrangement and form furnace chamber array; The quantity of described furnace chamber array has multiple, outwards arranges successively centered by described center furnace chamber 21.In the present embodiment, the periphery furnace chamber 22 of equidistant arrangement has two circles, and form two furnace chamber arrays, furnace chamber array forms multiple cellular furnace chamber 20 in body of heater 10.As shown in Figure 1, when using described resistance furnace, center furnace chamber 21 temperature is the highest, outside by center, is heat loss direction along radial direction, formation temperature gradient; First lap array furnace chamber is opened in distance center furnace chamber 21 a distance, has 8 the second furnace chambers 22; Second coil array furnace chamber opens the radial location in distance first lap more lateral, has 12 the second furnace chambers 22.
As shown in Figure 2, in the present embodiment, in each described furnace chamber 20, be provided with combustion chamber 30 and temperature control system (not shown), make each furnace chamber can carry out temperature control independently of one another.The heater strip 32 that combustion chamber 30 comprises boiler tube 31 and is positioned on described boiler tube.Described boiler tube 31 is hollow boiler tube, and described heater strip 32 is arranged around described boiler tube.When using resistance furnace heating, combustion chamber 30 is fixedly installed in furnace chamber, then the boiler tube 31 that will the workpiece of heating needed to put into combustion chamber 30, utilize heater strip 32 to heat, and control the temperature of combustion chamber 30 by controlling heater strip 32 by temperature control system.
As shown in Figure 3, the furnace chamber 20 of resistance furnace described in the utility model can run through described body of heater 10, also can not run through body of heater 10, freely can arrange according to the difference of workpiece to be processed.When furnace chamber 20 runs through described body of heater 10, can lie low resistance furnace placement, makes furnace chamber 20 be parallel to ground, now can put into workpiece to be heated by both direction; When furnace chamber 20 does not run through described body of heater 10, resistance furnace vertically can be placed, make furnace chamber 20 perpendicular to ground, now directly can put into workpiece to be heated from top.
The center furnace chamber 21 of above-described embodiment is cylindrical, multiple described periphery furnace chamber 22 is outwards arranged along described columniform radial direction, and the example of now heating to workpiece is as follows: combustion chamber 30 (comprising boiler tube 31 and heater strip 32) and the temperature control system of location arrangements 1200 degree in center furnace chamber 21; About 10 centimeters on center furnace chamber 21 radial direction, within the scope of 360 degree of radial location, evenly output 8 periphery furnace chambers 22 (its combustion chamber 30 comprises boiler tube 31 and heater strip 32) and respective independently temperature control system, realize the array furnace chamber of 900 degree; On distance center furnace chamber 21 radial direction, 360 degree of scopes of about 15 centimeters output 12 identical periphery furnace chambers 22 (its combustion chamber 30 comprises boiler tube 31 and heater strip 32), realize the independent furnace chamber array of 650 degree.
Above example obtains the furnace chamber workspace of three kinds of temperature: the furnace chamber of 1200 degree, and the furnace chamber of 8 900 degree of furnace chambers and 12 650 degree, can carry out the heat treatment of three kinds of temperature, totally 21 batches of workpiece simultaneously.
Another embodiment of the present utility model as shown in Figure 4, is similar to the situation of above-mentioned cylindrical center furnace chamber 21, and the center furnace chamber 21 in this embodiment is square, and center furnace chamber 21 temperature is 1200 degree.Thermograde due to square center furnace chamber 21 is main to spread along the direction perpendicular to the square length of side, therefore along the direction of the vertical described square length of side evenly being outputed 4 periphery furnace chambers 22 (its combustion chamber 30 comprises boiler tube 31 and heater strip 32) and respective independently temperature control system, each periphery furnace chamber 22 distance center furnace chamber 21 is apart from identical, and temperature is 900 degree; Output 4 periphery furnace chambers 22 again toward outside certain distance again, temperature is 650 degree.Such one heat treatment having three kinds of temperature can be carried out simultaneously, 1200 degree, a place, 4 900 degree, places, 4 650 degree, places, can process 9 batches of workpiece altogether simultaneously.
Resistance furnace of the present utility model comprises body of heater and is arranged at the furnace chamber in described body of heater, and furnace chamber comprises center furnace chamber and is looped around the periphery furnace chamber around the furnace chamber of described center.The utility model, on the thermograde direction of center furnace chamber, outputs new furnace chamber, to make full use of the heat loss effect in thermograde; Meanwhile, multiple periphery furnace chamber can also be made all to have the function of carrying out independent temperature control, reach the object that many furnace chambers work simultaneously.
Above example is applicable to multiple devices, power consumption minimizing 70%, improved efficiency more than 4 times.
Obviously, those skilled in the art can carry out various change and modification to utility model and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of the utility model claim and equivalent technologies thereof, then the utility model is also intended to comprise these change and modification.
