In fig. 1, the fire-proof valve with an alarm function 1, a thermocouple 2, a thermocouple temperature collector 3, a controllable relay 4, a display screen 5, a first warning device 6 and the like are included.
As shown in fig. 1, the utility model relates to a fritting furnace fire prevention valve structure, including main air pipe, main air pipe communicates several branch air pipe, branch air pipe intercommunication fritting furnace equipment air outlet, installation area alarming function's fire prevention valve 1 and thermocouple 2 among the branch air pipe, thermocouple 2 connects thermocouple temperature collector 3 inputs, and controllable relay 4 input and display screen 5 are connected respectively to thermocouple temperature collector 3 outputs, and first warning device 6 is connected to controllable relay 4 output.
The output end of the fire damper 1 with the alarm function is respectively connected with the input end of the safety relay 8 and the second warning device 7. The output end of the safety relay 8 is connected with a sintering furnace equipment power supply 9.
The main ventilating duct and the branch ventilating duct are made of stainless steel materials, have long service life and are not easy to corrode.
The fire damper 1 with the alarm function is characterized in that a proximity switch is arranged on the side of a fire damper valve plate of the fire damper, and when the temperature in the fire damper rises and a fuse wire is fused, the fire damper valve plate overturns to close a valve channel and simultaneously triggers the proximity switch to send out a fusing signal.
The thermocouple 2 converts the temperature in the branch ventilation pipeline into an electric signal and transmits the electric signal to the thermocouple temperature collector 3, and the model of the thermocouple 2 is PT 100.
A temperature preset value is set in the thermocouple temperature collector 3, and the temperature preset value is higher than the normal working temperature and lower than the fusing temperature of a fuse wire of a fire damper. This minimizes the consumption of the fire damper. The model of the thermocouple temperature collector 3 is 'JY-DAM-TC 08'.
And after receiving the signal of the thermocouple temperature collector 3, the controllable relay 4 opens and closes the first warning device 6.
The display screen 5 is an embedded integrated touch screen, and the model is 'TPC 7062TX (KX)'. The temperature in the current branch ventilation pipe can be displayed in real time for monitoring by operators.

The second warning device 7 is a rotary alarm lamp or a buzzer.
The controllable relay 4 and the safety relay 8 use small current to control the operation of large current.
The working process of the utility model is as follows:
the thermocouple 2 feeds back the temperature of the branch ventilation pipeline in real time, and when the temperature of the air outlet of the sintering furnace equipment rises to reach the preset alarm temperature, the thermocouple temperature collector 3 starts the first warning device 6 through the controllable relay 4.
When the temperature is continuously raised due to no measures taken by workers, the fuse wire in the fireproof valve 1 with the alarm function is fused, the fireproof valve plate is turned over to close the valve channel and simultaneously trigger the proximity switch, a fusing signal is sent to trigger the second warning device 7, the power supply 9 of the sintering furnace equipment is closed through the safety relay 8, and the sintering furnace mesh belt stops transmission and heating.
