Abstract
The utility model discloses a blower fan negative pressure detection control apparatus, including a sensor, a microprocessor and a frequency converter. The sensor and the frequency converter are respectively connected with the microprocessor by communication. In the utility model, the blower fan negative pressure detection control apparatus possesses the technology effects as following: when the real negative pressure is different from the set negative pressure, the air quantity of the blower fan is automatically adjusted to the value near the set negative pressure, the closed-loop automatic adjustment of the negative pressure is realized, and after the blower fan negative pressure detection control apparatus is arranged on the blower fan of a cigarette maker practically, the bearing process capability index of a tobacco rod can be raised by about 0.14 indicated by practical tests. Because the valve is open to the maximum degree, the requirement can be satisfied when the output frequency of the frequency converter is in the range from 40 to 45 Hz, electric energy is saved by about 10% to 15%, and simultaneously, the blower fan negative pressure detection control apparatus can be applied on the control of a dedusting blower fan or a wind supplying blower fan, which is convenient and practical.
Description
Technical field
The utility model relates to a kind of blower fan detection of negative pressure control gear, and particularly a kind of cigarette machine, dusting apparatus, wind of can be applicable to send the blower fan detection of negative pressure control gear in the blower fan control that equipment provides air quantity.
Background technique
At present, sending the negative pressure control of equipment fans such as equipment at cigarette machine, dusting apparatus, wind all is through manually coming regulating valve folding size to control, belonging to passive adjusting; So problem that exists adjustment to lag behind; And it is bigger that the adjustment of this negative pressure is influenced by shutdown and the startup of other boards, when the cigarette hands-operation, very easily causes pipe tobacco inhaling skewness on the silk ribbon especially; Influence the Cigarette Weight Control precision, the end product quality problem of unstable occurs.
The model utility content
Rely on adjusting manually in order to solve existing blower fan negative pressure adjustment; Can't accomplish according to circumstances to change real-time regulated; And negative pressure influences the inconstant technical problem of build-up of pressure because of receiving other aspects; The utility model provides a kind of close-loop automatic adjustment that can realize negative pressure, the blower fan detection of negative pressure control gear that automaticity is high.
In order to realize above-mentioned technical purpose, the technological scheme of the utility model is, a kind of blower fan detection of negative pressure control gear comprises sensor, microprocessor and frequency variator, and described sensor and frequency variator communication link respectively are connected to microprocessor.
Described a kind of blower fan detection of negative pressure control gear also comprises man-machine interface, and described man-machine interface communication link is connected to microprocessor.
Described a kind of blower fan detection of negative pressure control gear, described sensor is the blast transmitter.
Described a kind of blower fan detection of negative pressure control gear, described microprocessor is a programmable controller.
Described a kind of blower fan detection of negative pressure control gear, described man-machine interface is a text display.
The technique effect of the utility model is; When actual suction pressure and setting negative pressure are variant, regulate fan delivery automatically, make it to be stabilized near the negative pressure setting value; Realize the close-loop automatic adjustment of negative pressure; After as installed was on the cigarette machine blower fan, through actual test, the Zhi Chonggong Process capabi l i ty 32 index that cigarette props up can improve about 0.14.Because valve can reach maximum, the frequency variator output frequency is just can reach requirement between the 40--45Hz for this reason, so about saving power 10%-15%, the utility model also can be applicable on dedusting fan or the wind gas fan Electric Machine Control simultaneously, and is convenient and practical.
Below in conjunction with accompanying drawing the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, comprise sensor, microprocessor, man-machine interface and frequency variator, sensor is the blast transmitter, and microprocessor is that programmable controller is PLC, and man-machine interface is a text display.Sensor, man-machine interface and frequency variator communication link respectively are connected to microprocessor.The utility model is in when work, through blast transmitters sense pipe negative pressure, and after changing negative pressure signal into voltage (electric current) signal; This signal is exported to the analog amount load module of programmable controller; Programmable controller compares processing with setting value after computing, the control frequency variator is brought in the analog amount input that exports the analog output module of result through programmable controller to the control frequency variator then, when blast is higher than setting value; The Frequency Converter Control motor is run slowly; Otherwise, make the Frequency Converter Control motor quicken operation, thereby reach the running of adjusting motor speed stabilizing through frequency variator; That is to say and realize blower fan negative pressure close-loop automatic adjustment, finally reach the purpose of steady wind pressure.Text display is imported the setting value of negative pressure signal, so that the negative pressure of adjustment control at any time also is presented at negative pressure value on the display device simultaneously in real time.
