Abstract
The utility model is mainly used in electric heating steam generator, be specifically related to a kind ofly on electric heating steam generator, prevent heating tube dry burning device, the heater comprise water level probe, heating tube being heated and the control system be connected with heater, also comprise thermocouple and temperature controller, thermocouple is fixed on heating tube, temperature controller is arranged on the outside of electric heating steam generator body, and thermocouple, heater all connect temperature controller.Can the variations in temperature of Real-Time Monitoring heating tube by thermocouple fixing on heating tube; when at water level probe, malfunctioning or water level does not reach the scope that water level probe can measure; by thermocouple monitoring to heating tube temperature situation of change judge the duty of heating tube fast; when temperature controller monitor temperature exceedes setting value; can close by automatic control heating device; heating is stopped to heating tube; prevent heating tube dry combustion method; thus provide double shield for the safe heating of heating tube; available protecting heating tube, extends the service life of heating tube.
Description
Technical field
The utility model relates to and a kind ofly on electric heating steam generator, prevents heating tube dry burning device, belongs to electric heating steam generator field.
Background technology
At present, on market, the heating tube of most electric heating steam generator controls not protective device, normally control the duty of heating tube (that is: when the water level of water level probe detection reaches the low water level value of setting by water level probe detecting water level height, heating tube stops heating automatically), this independent control mode too relies on the reliability of water level probe, and water level probe is too harsh to the requirement of water quality, if malfunctioning at water level probe and there is no water extreme case under, heating tube is also working on, then can cause the fault that heating tube burns out, good measure is not also had to solve this problem at present.
Utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of reasonable in design for electric heating steam generator is provided and double shield can be provided for the safe heating of heating tube prevent heating tube dry burning device.
Described in the utility modelly on electric heating steam generator, prevent heating tube dry burning device, the heater comprise water level probe, heating tube being heated and the control system be connected with heater, also comprise thermocouple and temperature controller, thermocouple is fixed on heating tube, temperature controller is arranged on the outside of electric heating steam generator body, and thermocouple, heater all connect temperature controller.
Operation principle and process as follows:
When water level probe normally works, water level probe can water level in accurate detection electric heating steam generator body, when water level is lower than minimum (this minimum is not less than the peak of heating tube) that set, this water level information is fed back to control system by water level probe, and automatically close heater by control system, heating is stopped to heating tube, prevents heating tube dry combustion method.
When water level probe is malfunctioning or water level in electric heating steam generator does not reach the scope that water level probe can measure, water level probe cannot detect water level conditions, also cannot be controlled heating tube by control system.But when water level is lower than heating tube, heating tube can temperature raise in a heated state gradually, the thermocouple be fixed on heating tube can carry out Real-Time Monitoring to the temperature of heating tube and temperature signal be fed back to temperature controller, when the heating tube temperature detected too high (exceeding the maximum temperature value that temperature controller sets), temperature controller will control heater and automatically close, and prevents heating tube dry combustion method.
In sum, the utility model is that the safe heating of heating tube provides double shield, thus available protecting heating tube, prevent its dry combustion method, extend its service life.
The beneficial effect that the utility model is compared with prior art had is:
This apparatus structure is simple, reasonable in design, can the variations in temperature of Real-Time Monitoring heating tube by thermocouple fixing on heating tube, when at water level probe, malfunctioning or water level does not reach the scope that water level probe can measure, by thermocouple monitoring to heating tube temperature situation of change judge the duty of heating tube fast, by the temperature-measurement principle of thermocouple, when temperature controller monitor temperature exceedes setting value, can close by automatic control heating device, heating is stopped to heating tube, prevent heating tube dry combustion method, thus provide double shield for the safe heating of heating tube, available protecting heating tube, extend the service life of heating tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, water level probe; 2, heating tube; 3, thermocouple; 4, electric heating steam generator body; 5, temperature controller.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
Originally heating tube dry burning device is prevented to be mainly used on electric heating steam generator, its structure as shown in Figure 1, mainly comprise water level probe 1, heater, thermocouple 3 and temperature controller 5, thermocouple 3 is fixed on heating tube 2, Real-Time Monitoring is carried out to the variations in temperature of heating tube 2, temperature controller 5 is arranged on the outside of electric heating steam generator body 4, thermocouple 3, heater all connect temperature controller 5, heater is used for the heating to heating tube in electric heating steam generator 2, heater connection control system.
The utility model is that the safe heating of heating tube provides double shield, thus available protecting heating tube, prevents its dry combustion method, extends its service life, its operation principle and process as follows:
(1) when water level probe 1 normally works, water level probe 1 can water level in accurate detection electric heating steam generator body 4, when water level is lower than minimum (this minimum is not less than the peak of heating tube 2) that set, this water level information is fed back to control system by water level probe 1, and automatically close heater by control system, heating is stopped to heating tube 2, prevents heating tube dry combustion method.
(2) when water level probe 1 is malfunctioning or water level in electric heating steam generator does not reach the scope that water level probe 1 can measure, water level probe 1 cannot detect water level conditions, also cannot be controlled heating tube by control system.But when water level is lower than heating tube 2, heating tube 2 can temperature raise in a heated state gradually, the thermocouple 3 be fixed on heating tube 2 can carry out Real-Time Monitoring to the temperature of heating tube 2 and temperature signal be fed back to temperature controller 5, when heating tube 2 temperature detected too high (exceeding the maximum temperature value of setting on temperature controller 5), temperature controller 5 will control heater and automatically close, and prevents heating tube dry combustion method.
Claims (1)
1. one kind prevents heating tube dry burning device on electric heating steam generator, the heater comprise water level probe (1), heating tube being heated and the control system be connected with heater, it is characterized in that: also comprise thermocouple (3) and temperature controller (5), thermocouple (3) is fixed on heating tube (2), temperature controller (5) is arranged on the outside of electric heating steam generator body (4), and thermocouple (3), heater all connect temperature controller (5).
