Fig. 2 is intermediate frequency furnace body baker isolating construction schematic diagram described in the utility model.
Among the figure:
The 1-heater; The 2-pedestal; Temperature sensor in the 3-stove; The outer temperature sensor of 4-stove; The 5-electric cabinet; The 6-binding post; The 7-furnace lining; The 8-connecting line.
The specific embodiment
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings:
Such as Fig. 1, shown in Figure 2, a kind of intermediate frequency furnace body baker of the present utility model, comprise temperature sensor 3 in the stove, the outer temperature sensor 4 of stove, heater 1, binding post 6, furnace lining 7 according to the different size size, select the heater 1 of different capacity, after being connected and fixed with pedestal 2 stainless steels, binding post 6 adopts as required △ corner connection or Y star to connect wire and wears porcelain tube outward, temperature sensor is located at pedestal 2 lower surface central parts and is fixedly connected with line 8 and passes from pedestal 2 upper surfaces, mid portion is filled alumina silicate fibre or rock wool, its effect is heat insulation and insulation, on, lower stainless steel pedestal 2 usefulness screw mandrel overcoat heat-barrier materials fix, and not only structure uniqueness and heat insulating effect are very good for it.Heater 1 is connected with electric cabinet 5, and the outer temperature sensor of body of heater is connected with electric cabinet 5.Heater 1 connects (can according to power selection) 3*X2+1 wire with adopting the conductor wire end aviation plug being connected of electric cabinet 5.Temperature sensor 3 can adopt the conductor wire end aviation plug to be connected with electric cabinet 5 in the stove.The outer temperature sensor 4 of stove adopts the conductor wire end aviation plug to be connected with electric cabinet 5.Can be connected with thermometer by band switch in the electric cabinet 5, rotatable band switch shows the temperature of diverse location when temperature detection, and can as required temperature be printed.
Electric electric power system adopts Intelligent temperature control device, and it is controlled by the automatic instrument of 4-20MA/ PWM number or the manual setting signal of temperature controller or the output of other equipment, produces cycle zero passage formula.(PWM Duty ratio control) and two kinds of outputs of cycle zero passage formula (CYC limit cycle) are controlled its power output by the cycle of regulating conducting in the unit interval, thereby realize the automatic adjusting of temperature in the heating system.Electric power system has high-resolution, temperature fluctuation is little, continuously adjustable characteristics, be a kind of novel temperature control mode, noise is little during controlling run, the life-span long, efficient sets high than electromagnetic installing, is conducive to save energy and reduce the cost, the sine voltage zero passage is open-minded, current over-zero turn-offs, and output is sinusoidal wave completely, so radiation, transmission disturbs little and the electrical surge electric current is also little.
Heater adopts the design of new ideas design idea, and pedestal 2 profiles, the cold system of pedestal 2 material selection corrosion resistant plates form, just like flying saucer in the sky.All polish on upper and lower surface, and it is anticorrosion, favorable rust preventing effect under the environment of weak acid, weak base, humidity, and its lower surface can effectively reflex to far infrared the action effect that furnace lining 7 inwalls fully play far infra-red heater 1 simultaneously.Thermal source is supplied with and is adopted far infra-red heater 1, main is that its far infrared refraction heat by conduction in quartz sand (or magnesia) furnace lining 7 is can effect good especially, and its distinctive contour structures design can not replace other heaters 1, it has uniqueness simple in structure, and heat conduction and the thermal efficiency are high.
The process of baker: intermediate frequency furnace and water circulation water pump need not start, baker is put into the furnace lining 7 that has knotting, heater 1 and electric cabinet 5 are connected by the wire aviation plug, each temperature sensor lead aviation plug connects, the outer temperature sensor 4 of stove is fixed between the controlled intermediate frequency furnace induction coil and installs, electric cabinet 5 energisings, the design temperature curve also can directly use manually etc., when just having begun to heat, heater 1 pedestal 2 can some slits be arranged with fire door, mainly be in heating process, to discharge some moisture, can be with heater 1 pedestal 2 and the sealing of stove inwall after 4-6 hour, all act on energy in the stove, thermal conductance and heat energy are forced out the outside from inside to outside with moisture and the boric acid crystallization water of quartz sand in the stove (magnesia), the induction coil in the outside, aqueous vapor condensation on bakelite bar and the yoke can occur, the aqueous vapor condensation can be in the situation that continuous rising of temperature of furnace wall distributes gradually, until oven dry, insulation all right (time is generally at the 16-24 hour) body of heater in the body of heater outside is dried rear outage.Take out the temperature sensor of stove outside each point and keep well, be placed on the fixed position, in order to using next time, disconnect each aviation plug, take out heater 1, throw low-carbon (LC) become rusty less steel material or normally blow-on smelting of iron charge, temperature is about 1550-1600 ℃.
Adopting intermediate frequency furnace body is the class roaster, it is not only energy-conservation, consumption reduction, environmental protection, to zero loss of equipment bake process, and available 1 people, can be interrupted monitoring and judge the baker effect, and greatly save furnace drying time, more energy-conservation than the safer low-carbon environment-friendly of other baker mode, what baking quality did not have especially says, intermediate frequency furnace body baker structural design is simple in a word, fashion, heat energy, heat conduction efficiency is high, high insulating effect, it is in safety, energy-conservation, consumption reduction, environmental protection aspect successful, it is saving manpower, material resources, the aspects such as furnace drying time are remarkably productive, more outstanding is that coming into operation of it is reduced to zero to equipment loss, body to intermediate frequency furnace uses the safe life raising that positive effect is arranged, and cured effect is very good, can say that it is that the intermediate frequency furnace body oven dry is first-selected, his utilization can be described as the revolution of intermediate frequency furnace body stoving process, and the raising of body of heater stoving process is had positive impact and effect.
