Abstract
The utility model relates to a kind of intermediate frequency furnace automatic safety device; comprise control circuit, the first infrared sensor, the second infrared sensor and control the magnetic valve that heating system is closed; wherein the first infrared sensor is arranged on intermediate frequency furnace charging aperture; the second infrared sensor is arranged on intermediate frequency furnace discharging opening; the signal that the first infrared sensor and the second infrared sensor sense sends control circuit to, and control circuit is controlled the shutoff of magnetic valve according to signal condition.Sensor detects and adds thermal material when discontinuous, and heating system automatically shuts down.The utility model is realized heating power and is automatically controlled, and reaches the object of protection heating furnace, and simple in structure, easily realizes.
Description
Technical field
The utility model relates to apparatus for melting metal, is specially a kind of automatic safety device of intermediate frequency furnace.
Background technology
In forging industry, add thermal recovery drill autofeeder, according to the time of design, carry out step promotion and add thermal material, intermediate frequency furnace will be according to predefined power parameter, carry out power stage, conventionally the power of output and continuously the object forming energy balance of propelling heating, the temperature in stove remains on stationary value.But when advance add thermal material and occur non-continuous event time, constant due to power output, the temperature in stove is by fast rise, there is hot melt in the material of heating, easily damages and lost efficacy.
Utility model content
The technical problems to be solved in the utility model is that in stove, temperature keeps constant, makes to add thermal material and occurs hot melt when adding thermal material and advance intermediate frequency furnace discontinuous.
For achieving the above object, the utility model provides a kind of intermediate frequency furnace automatic safety device, and sensor detects and adds thermal material when discontinuous, and heating system automatically shuts down.
The utility model is achieved through the following technical solutions: a kind of intermediate frequency furnace automatic safety device; comprise control circuit, the first infrared sensor, the second infrared sensor and control the magnetic valve that heating system is closed; wherein the first infrared sensor is arranged on intermediate frequency furnace charging aperture; the second infrared sensor is arranged on intermediate frequency furnace discharging opening; the signal that the first infrared sensor and the second infrared sensor sense sends control circuit to, and control circuit is controlled the shutoff of magnetic valve according to signal condition.
Because the temperature of charge of being discharged by discharging opening after intermediate frequency heating is higher, the second infrared sensor is preferably high temperature resistant sensor.
When asymmetric information that the first infrared sensor and the second infrared sensor sense, by control circuit, control closed electromagnetic valve heating system.The unlatching of magnetic valve needs Artificial Control.Magnetic valve cuts out heating system by controlling transmission device, and the speed of transmission device is adjustable.
Control circuit is M68HC16 type single-chip microcomputer, and its peripheral circuit is superior element and the shielding device of anti-electromagnetic interference performance preferably.
The utility model adopts jamproof integrated circuit, according to existing equipment frequency, automatically detects continuity material-to-be-heated in production process, thereby realize heating power, automatically controls, and reaches the object of protection heating furnace.And simple in structure, easily realize.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Reference numeral: 1-intermediate frequency furnace; 2-add thermal material; The 3-the first infrared sensor; The 4-the second infrared sensor; 5-control circuit; 6-magnetic valve; 7-transmission device.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, add thermal material 2 and enter intermediate frequency furnace 1 from feeding mouth, after heating, from discharging opening, discharge.The first infrared sensor 3 is set at feeding mouth place, and discharging opening arranges the second infrared sensor 4, and wherein the second infrared sensor 4 is high temperature resistant sensor.When adding thermal material 2 according to the continuous inlet/outlet of certain frequency, the first infrared sensor 3 is identical with the signal that the second infrared sensor 4 senses, control circuit 5 is not done trigger action; When adding thermal material 2 when discontinuous, the first infrared sensor 3 is different with the signal that the second infrared sensor 4 senses, and converts the different signals of telecommunication to, makes control circuit 5 trigger magnetic valve 6, magnetic valve 6 drives transmission device 7 to cut out intermediate frequency furnace 1, stops the heating to material.But the unlatching of heating system need to manually be carried out, to guarantee the reliability of start.Control circuit 5 can be relay and peripheral circuit, single-chip microcomputer and peripheral circuit thereof, but is not limited to this, and all circuit that can realize sensor-lodging and can trigger magnetic valve 6 turn-off functions all drop in protection domain of the present utility model.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned embodiment, also comprises the technical scheme being comprised of above technical characterictic.
