Abstract
The utility model discloses an energy-saving safety device for an electromagnetic heated crucible. The outer wall of the crucible is provided with a temperature sensing probe connected with a programmable controller; the programmable controller is connected with a heating resonator; the heating resonator is in a connection with a sensing coil; the temperature sensing probe collects temperature data and then transmits the data to the programmable controller; and the programmable controller sends out a signal to the heating resonator to control connection or disconnection of the sensing coil. By the use of the energy-saving safety device of electromagnetic heated crucible, a temperature of the outer wall of the crucible can be controlled in a rational range, thereby achieving a purpose of energy saving and safety guaranteeing.
Description
Technical field
The utility model relates to the crucible heating of alloy material electromagnetism smelting furnace to be controlled, particularly a kind of Electromagnetic Heating crucible energy-saving safeguard device.
Background technology
At present, the alloy material electromagnetism smelting furnace using in industry is the state that adopts continuous high temperature heating, and the inner and outer wall temperature difference of crucible is larger, does not make full use of heat conduction, cause the waste of heat, meanwhile, the excess Temperature of outer wall, easily cause loss of excitation, damage controller, poor stability.
Utility model content
The purpose of this utility model is to provide a kind of Electromagnetic Heating crucible energy-saving safeguard device, and the outside wall temperature of crucible is controlled in the reasonable scope, reaches energy-conservation and safe object.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of Electromagnetic Heating crucible energy-saving safeguard device, at crucible outer wall, temperature sense probe is installed, temperature sense probe is connected with Programmable Logic Controller PLC, Programmable Logic Controller is connected with heating resonator, heating resonator is connected with induction coil, temperature sense probe collecting temperature data are transferred to Programmable Logic Controller by signal, and Programmable Logic Controller sends signal to heating resonator, controls induction coil energising or power-off.
Described temperature sense probe is thermocouple.
Described induction coil is around the home on the outer wall of crucible.
Adopt after such scheme, the outside wall temperature that the utility model can be controlled crucible in the reasonable scope, when reaching default definite value (as 600 ℃), the outside wall temperature of crucible stops heating, because the inner wall temperature of crucible can be well below outside wall temperature, so now although heating system stops heating, still can make full use of outside wall temperature and play energy-saving effect to inwall conduction, the outer wall of while crucible reaches 600 ℃ and is easy to above loss of excitation, the moment electromagnetic field of loss of excitation discharges nowhere and easily causes controlling aircraft bombing, the utility model has been controlled the outside wall temperature of crucible effectively, not only can avoid damaging heating element heater and controller, more can reach safe object.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model has disclosed a kind of Electromagnetic Heating crucible energy-saving safeguard device, at crucible 1 outer wall, thermocouple 2 is installed, thermocouple 2 is connected with Programmable Logic Controller 3, Programmable Logic Controller 3 is connected with heating resonator 4, heating resonator 4 is connected with induction coil 5, and induction coil 5 is around the home on the outer wall of crucible 1.
During the utility model work, thermocouple 2 collecting temperature data, signal is transferred to Programmable Logic Controller 3, when the outside wall temperature of crucible 1 reaches default definite value (as 600 ℃), Programmable Logic Controller 3 sends to heating resonator 4 signal that stops heating, control induction coil 5 and can not produce magnetic field in off-position, thereby reach the object that stops heating.
The utility model is because install temperature sense probe (thermocouple 2) in the outer wall employing of crucible 1, the outside wall temperature of crucible 1 is controlled in 600 ℃, when the outside wall temperature of crucible 1 reaches 600 ℃, the inner wall temperature of crucible 1 can be well below 600 ℃, now heating system can stop heating, and make full use of outside wall temperature, to inwall, conduct, play energy-saving effect, the outside wall temperature of while crucible 1 reaches 600 ℃ and is easy to above loss of excitation, the moment electromagnetic field of loss of excitation discharges nowhere and easily causes controlling aircraft bombing, after stopping heating, controlled temperature rising, avoid outside wall temperature to reach more than 600 ℃, reach safe object.
