Abstract
The utility model discloses a hot air control system for a process fan of a cut tobacco expansion line. The hot air control system comprises a PID controller, a wind speed sensor and a frequency converter for controlling rotating speed of the hot air process fan. The wind speed sensor acquires wind speed of hot air, the signal output end of the wind speed sensor is connected with the PID controller connected with a wind speed setting unit, the signal output end of the PID controller is connected with the frequency converter, and the frequency converter controlling the rotating speed of the hot wind process fan can achieve automatic adjustment of the wind speed and ensure stable wind speed. The hot air control system is low in cost, can improve the effective operation rate of a device, and further can reduce energy consumption of a motor in the production process, reduce vibration of the motor and prolong the service life of the motor.
Description
Technical field
The utility model relates to a kind of tobacco pipe tobacco manufacturing, relates in particular to a kind of novel tobacco shred expansion line technique blower fan hot blast control system.
Background technique
At present, in the expansion system of tobacco workshop carbon dioxide bulked thread hot junction, it is 30 meter per seconds that the wind speed of hot blast requires, and current hot blast control principle is the rotating speed of stationary heat wind process blower fan, and realizes by the aperture that regulates hot blast air door.And technique air damper controller adopts, be the equipment of German AOMA company, more expensive; The motor of hot air technique blower fan is by transducer drive, and frequency setting is 45HZ.There are two problems in this pattern: the one, increase investment, and need to increase air damper controller, if there is fault, both increased spare part investment, increase again maintenance load; The 2nd, can not give full play to efficiency and the function of frequency variator, motor consumption is large.
Model utility content
The purpose of this utility model is to provide a kind of tobacco expanding Wiring technology blower fan hot blast control system, can realize the automatic adjusting of wind speed and guarantee that wind speed is stable, raising equipment efficiency.
The utility model adopts following technical proposals: a kind of tobacco expanding Wiring technology blower fan hot blast control system, include the frequency variator of PID controller, air velocity transducer, control hot air technique rotation speed of fan, described air velocity transducer gathers the wind speed of hot blast, the signal output part of air velocity transducer connects PID controller, described PID controller is connected with wind speed setup unit, the signal output part of PID controller connects frequency variator, the signal output part of frequency variator connects hot air technique blower fan, controls the rotating speed of hot air technique blower fan.
The setting value of described wind speed setup unit is 30 meter per seconds.
The utility model is for the problem of prior art, by controlling frequency variator, thereby the rotating speed of controlling hot air technique blower fan is controlled the wind speed of hot blast, can realize the automatic adjusting of wind speed and guarantee that wind speed is stable, cost is low and can improve equipment efficiency, can also lower motor in production process energy consumption, reduce the vibration of motor, extend the working life of motor.
Accompanying drawing explanation
Fig. 1 is control block diagram of the present utility model.
Embodiment
According to existing appointed condition, by analysis, abandon recruitment ethics and practice door controller completely and go to change the aperture of air door, remove air damper controller circuit, change the wind speed of being controlled hot blast by the rotating speed that regulates hot air technique blower fan into.
As shown in Figure 1, the utility model discloses a kind of tobacco expanding Wiring technology blower fan hot blast control system, include the frequency variator of PID controller, air velocity transducer, control hot air technique rotation speed of fan, described air velocity transducer gathers the wind speed of hot air technique blower fan, the signal output part of air velocity transducer connects PID controller, described PID controller is connected with wind speed setup unit, the signal output part of PID controller connects frequency variator, thereby frequency variator connects the rotating speed of hot air technique blower fan control hot air technique blower fan.Wherein PID controller can pass through chip microcontroller.
The utility model is the closed loop control system of a standard, and the setting value of wherein said wind speed setup unit is 30 meter per seconds (can change as requested).After the actual wind speed that wind speed setting and air velocity transducer record is subtracted each other, deviation signal is as the input signal of PID controller, and the frequency of the output signal control frequency variator of PID controller is controlled the rotating speed of hot air technique blower fan, thereby controls the wind speed of hot blast.
Claims (2)
1. a tobacco expanding Wiring technology blower fan hot blast control system, it is characterized in that: the frequency variator that includes PID controller, air velocity transducer, control hot air technique rotation speed of fan, described air velocity transducer gathers the wind speed of hot blast, the signal output part of air velocity transducer connects PID controller, described PID controller is connected with wind speed setup unit, the signal output part of PID controller connects frequency variator, and the signal output part of frequency variator connects hot air technique blower fan, controls the rotating speed of hot air technique blower fan.
2. tobacco expanding Wiring technology blower fan hot blast control system according to claim 1, is characterized in that: the setting value of described wind speed setup unit is 30 meter per seconds.
