Abstract
The invention discloses a kind of vacuum-control(led) systems and paper machine for paper machine, wherein the vacuum-control(led) system includes vacuum pump, discharge duct, drive motor, frequency converter and vacuum pipe, the discharge duct, vacuum pump and vacuum pipe are sequentially connected, the vacuum pump is connected with drive motor and frequency converter, at least one absorption vacuum tank is provided on the vacuum pipe, the absorption vacuum tank side is provided with vacuum meter.Paper machine added with vacuum control system provided by the present invention can be realized to the control of drive motor reduction of speed by changing the frequency of frequency converter, be finally reached the control to vacuum degree, to meet technique productions requirement.
Description
Technical field
The present invention relates to a kind of paper machine, more particularly to a kind of vacuum-control(led) systems and paper machine for paper machine.
Background technology
The physics of specialty board and electrical characteristic transformer safety can be stablized long-term hanging net operation have it is most important
Effect.The inter-layer bonding force of cardboard is exactly one of index, this is related to the dehydration control of papermaking link, directly affects the index performance
It is exactly the vacuum degree control in paper-making process, vacuum degree cannot be adjusted, and the cardboard produced is easy layering, not only affects production
The quality of product, and also cause energy waste.
Invention content
To overcome paper machine vacuum degree existing in the prior art cannot be adjusted, the cardboard produced is easy asking for layering
Topic, the present invention provides a kind of vacuum-control(led) systems and paper machine for paper machine.
Specific technical solution is as follows：
A kind of vacuum-control(led) system for paper machine, including vacuum pump, discharge duct, drive motor, frequency converter and true
Vacant duct, the discharge duct, vacuum pump and vacuum pipe are sequentially connected, the vacuum pump and drive motor and frequency converter phase
Even, it is provided at least one absorption vacuum tank on the vacuum pipe, the absorption vacuum tank side is provided with vacuum meter.
Preferably, there are two absorption vacuum tanks for setting on the vacuum pipe, and are correspondingly arranged on vacuum meter respectively.
Preferably, the frequency of the frequency converter is 20Hz~40Hz.
Preferably, the frequency of the frequency converter is 28Hz.
A kind of paper machine, including it is used for the vacuum-control(led) system of paper machine as described above.
The present invention has the advantages that compared with prior art：
(1) paper machine provided by the present invention is closed by resetting the running frequency parameter inside frequency converter to find
Suitable vacuum degree, the perfect modification scope of vacuum degree meet more products specification but also production vacuum ranges are wider
It is required that.
(2) paper machine provided by the present invention can set suitable vacuum in production process according to product specification
Degree loads without prolonged oepration at full load, changes the frequency of frequency converter, also by the V/F control modes of frequency converter
The input voltage for changing drive motor, reduces running current, reduces whole operation cost.
Description of the drawings
Fig. 1 is a kind of vacuum-control(led) system structure chart for paper machine of the invention.
In figure, 1- frequency converters, 2- motors, 3- adsorbs vacuum tank, and 4- vacuum meters, 5- vacuum pipes, 6- discharge ducts, 7- is true
Sky pump.
Specific implementation mode
The specific implementation mode of the present invention is described further below in conjunction with the accompanying drawings.It should be noted that for
The explanation of these embodiments is used to help understand the present invention, but does not constitute limitation of the invention.In addition, disclosed below
The each embodiment of the present invention in involved technical characteristic can be combined with each other as long as they do not conflict with each other.
The invention discloses a kind of vacuum-control(led) systems for paper machine, as shown in Figure 1, including vacuum pump 7, exhaust pipe
Road 6, drive motor 2, frequency converter 1 and vacuum pipe 5, discharge duct 6, vacuum pump 7 and vacuum pipe 5 are sequentially connected, vacuum pump 7
It is connected with drive motor 2 and frequency converter 1, at least one absorption vacuum tank 3,3 side of absorption vacuum tank is provided on vacuum pipe 5
It is provided with vacuum meter 4.Preferably, there are two absorption vacuum tanks 3 for setting on the vacuum pipe 5 in the present invention, and correspondence is set respectively
It is equipped with vacuum meter 4.The setting of the vacuum meter 4 can directly observe the vacuum degree of field pipes.Preferably, frequency converter in the present invention
1 frequency is 20Hz~40Hz, the frequency converter frequency setting range 0-50Hz, and the working frequency for meeting manufacturing technique requirent sets
Determine range 20Hz~40Hz.It is further preferred that the frequency of frequency converter 1 is 28Hz.It is seen by adjusting the different frequency of frequency converter 1
Cases of dehydration on wet paper machine when making, increases frequency converter 1, control of the frequency to vacuum degree may be implemented by operation panel,
Such as when the frequency of frequency converter 1 is 50Hz or so, corresponding l Water Paper moisture is 68%, and left and right, vacuum degree is -0.05mpa；Work as frequency converter
1 frequency is 28Hz or so, and corresponding l Water Paper moisture is 80% or so, and vacuum degree is -0.02mpa.Due to original vacuum control
Be driving to vacuum motor 2 is realized by soft start, once but after system stable operation its operation load be at full capacity,
So vacuum degree can reach a uncontrollable maximum value, this is by product structure, motor type selecting, papermaking vacuum structure institute
Congenital decision.If being not necessarily to the vacuum degree of bigger in production process, after the present invention changes the frequency of frequency converter 1,
The input voltage that drive motor 2 is also just changed by the V/F control modes of frequency converter 1 reduces running current, whole fortune
Battalion's cost can decline.Further, manual modulation valve is had additional on the vacuum pipe 5 in the present invention, by adjusting this valve
Aperture allows into a part of air in vacuum pipe 5, to reach required vacuum degree control requirement.
The present invention also provides a kind of paper machines, including the above-mentioned vacuum-control(led) system for paper machine.
Embodiments of the present invention are explained in detail above in association with attached drawing, but the present invention is not limited to described implementations
Mode.For a person skilled in the art, in the case where not departing from the principle of the invention and spirit, to these embodiments
A variety of change, modification, replacement and modification are carried out, are still fallen in protection scope of the present invention.
