Detailed Description

The utility model is further explained below with reference to the drawings and the embodiments.

Please refer to fig. 1, this embodiment provides an automatic control device for a high temperature furnace in a laboratory, which includes a control unit, an ac contactor, an integrated muffle furnace, a temperature measurement module, a timing module and an audible and visual alarm module; the control unit is used for sequentially connecting the alternating current contactor and the integrated muffle furnace; the integrated muffle furnace is also connected with a timing module and an acousto-optic alarm module respectively; the control unit is also connected with the temperature measuring module, the timing module and the acousto-optic alarm module respectively.

In the embodiment, preferably, the control unit adopts a leading control ZK2N-1-PLC control module;

in the embodiment, the temperature measuring module preferably adopts a PT100-K type temperature sensor.

In this embodiment, preferably, the timing module uses an SRD-05VDC band signal input time switch.

In the present embodiment, an 220/380V ac contactor is preferably used as the ac contactor.

In this embodiment, the device operates as follows:

(1) the whole device is powered on, temperature (for example, 550 ℃) and time (for example, 2 hours) parameters are set on the PLC control unit and the high-temperature furnace, and the device is started. At the moment, the high-temperature furnace is electrified to work, the temperature measuring module also starts to work, the temperature in the furnace is monitored in real time, and when the temperature in the furnace reaches a preset temperature (for example, 550 ℃), a signal is given to the control unit to tell the control unit that the temperature reaches a set degree.

(2) The control unit receives that the temperature reaches the set degree, gives a signal to the timing module, and the timing module starts to count down for 2 hours, and sends a power-off signal to the control unit after 2 hours.

(3) After receiving the signal, the control unit triggers the alternating current contactor to power off, triggers the alarm module to make a sound and an indicator lamp to alarm, and reminds workers.

The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
