In the present embodiment, control cabinet 230 further includes distributor 232 and analog-to-digital conversion module 234, pressure transmitter 220
It passes sequentially through distributor 232 and analog-to-digital conversion module 234 is electrically connected with display device 236.Fig. 3 is pressure in the embodiment of the present invention
Wiring diagram between transmitter 220 and control cabinet 230.Distributor 232 provides 24V DC power supply, pressure to pressure transmitter 220
The barometric information of acquisition is transferred to distributor 232 with the current signal of 4-20mA by transmitter 220, then is isolated by distributor 232
It exports to analog-to-digital conversion module 234.Current signal is calculated the number letter being converted into comprising pressure information by analog-to-digital conversion module 234
It number is transferred to display device 236, display device 236 and then shows the pressure information in flue 110, it thus can be to flue
110 pressure carries out on-line checking.
Specifically, the electric current that pressure transmitter 220 exports is linearly related with the pressure value detected, such as pressure transmitter
220 range is -300Pa~0Pa (relative value that pressure value here is relative standard's atmospheric pressure), and -300Pa corresponds to 4mA,
0Pa then corresponds to 20mA, then the every change 1mA of electric current means that actual pressure changes 18.75Pa.If digital-to-analogue conversion module
Received current value is 12mA, then the pressure in furnace is -150Pa.When the air pressure change of flue 110, corresponding milliampere value
Linear change therewith thus can carry out on-line checking to the air pressure of flue 110.In this way, it can also monitor every
The variation of air pressure when secondary pumping records the air pressure change curve of flue 110.
It is appreciated that in other embodiments of the invention, what the air pressure range and correspondence of pressure transmitter 220 exported
Current value range can also be changed as needed；Distributor 232 can also basis to the voltage that pressure transmitter 220 exports
Actual conditions are adjusted, for example are adjusted between 18.5V~28.5V.
In embodiments of the present invention, it is connected between pressure transmitter 220 and distributor 232 by fire resistant shielding cable,
To resist destruction of the hot environment to cable.
Flue air pressure measuring apparatus 200 provided in an embodiment of the present invention and furnace flue structure 100 can facilitate, stablize
Ground detects the air pressure in flue 110, to help technical staff preferably to control the negative pressure in flue 110, keeps kiln
The micro-positive pressure of furnace interior.By setting three-way connection 216 and plug 218, the cleaning of pressure pipe can be made to become convenient.Pass through
High temperature resistant stainless steel is reasonably set by the first tube body 210, the second tube body 212, equipment is further enhanced and transports at high temperature
Capable stability.Digital signal is converted analog signals by analog-digital commutator to export to display device 236, can facilitate skill
Art personnel preferably observe and record.
Fig. 4 is the flow chart of flue air pressure measurement method provided in an embodiment of the present invention.The embodiment of the present invention also provides one
Kind flue air pressure measurement method, applies flue air pressure measuring apparatus 200 provided in this embodiment, this method comprises:
Step S100, pressure transmitter detect the air pressure in flue by pressure pipe.
In the present embodiment, pressure transmitter 220 detects the air pressure in flue 110, pressure transmitter 220 in the present embodiment
Range be -300Pa~0Pa (relative value that pressure value here is relative standard's atmospheric pressure).
Step S200, display device show the pressure information in flue 110 according to the air pressure that pressure transmitter detects.
In the present embodiment, pressure transmitter 220 exports 4mA~20mA to distributor 232 according to the pressure value detected
Electric current, then by the isolation output of distributor 232 to analog-to-digital conversion module 234, analog-to-digital conversion module 234 is by current signal (simulation
Signal) it is converted into digital signal and is sent to display device 236, display device 236 shows pressure information according to the signal.For example ,-
300Pa corresponds to 4mA, and 0Pa then corresponds to 20mA, then the every change 1mA of electric current means that actual pressure changes 18.75Pa.Such as
The received current value of fruit digital-to-analogue conversion module is 12mA, then the pressure in furnace is -150Pa.When the air pressure change of flue 110,
Corresponding milliampere value also linear change therewith, thus can carry out on-line checking to the air pressure of flue 110.Pass through this side
Formula, the variation of air pressure when can also monitor each pumping record the air pressure change curve of flue 110.
