Abstract
The invention relates to a fan control device. The fan control device comprises a remote-transmitting pressure gauge, a pressure sensor, a draught fan, a frequency changer, a transmitter and a PID (Proportion Integration Differentiation) regulator, wherein the remote-transmitting pressure gauge, the pressure sensor and the draught fan are arranged on a flue, the frequency changer is connected to a fan motor on the draught fan, and the transmitter is connected to the pressure sensor; and the remote-transmitting pressure gauge, the PID regulator and the transmitter are connected to the frequency changer. The pressure sensor is used for measuring an actual pressure value in the flue and transmitting a signal value to the frequency changer through the transmitter, the PID regulator is used for regulating required set pressure, the remote-transmitting pressure gauge is used for transmitting a set pressure numerical signal to the frequency changer, and the frequency changer automatically regulates alternating-current frequency so as to control the rotating speed of the fan motor in a manner that the comparison between the signal of the pressure sensor and the set pressure signal of the remote-transmitting pressure gauge is aimed, thereby realizing an accurate wind pressure regulation role.
Description
Technical field
The present invention relates to a kind of electric control equipment, be specifically related to a kind of fan controller.
Background technique
Aluminum carbon anode production is the process of one-period, and requirement can provide according to the needs in cycle suitable negative pressure.As shown in Figure 1, in actual production, usually adopt at the two ends of flue 1 valve plate 2 is installed, control the size of electric precipitation 3 and induced draught fan 4 required blast by the switching value of valve plate 2.Utilize valve plate 2 control blast to have inconvenient operation, the large energy consumption of resistance is high, the drawback of control accuracy low precision.
Summary of the invention
The present invention provides a kind of fan controller in order to overcome the deficiency of above technology.
The present invention overcomes the technological scheme that its technical problem adopts:
This fan controller, comprise distance-transmission pressure gauge, pressure transducer and the induced draught fan that is arranged on the flue, the frequency variator that is connected in the fan motor on the induced draught fan, the transmitter that is connected in pressure transducer and PID regulator, described distance-transmission pressure gauge, PID regulator and transmitter are connected in frequency variator.
The invention has the beneficial effects as follows: pressure transducer is used for measuring the actual pressure value of flue and by transmitter signal value is passed to frequency variator, regulate required setting pressure by PID, distance-transmission pressure gauge is sent to frequency variator with the setting pressure numerical signal, frequency variator is regulated a-c cycle with the rotating speed of control fan motor automatically for the setting pressure signal of the signal contrast distance-transmission pressure gauge of pressure transducer, thereby realizes the effect of fine adjustment blast size.
