Fig. 2 is the block diagram of the pipe tobacco separator in the tobacco leaf dedusting system of machine for cutting of the present invention.
The specific embodiment
Basic design of the present invention is the wind speed in the cleaning shaft to be remained between first target wind speed and second target wind speed, thereby pipe tobacco and flue dust are separated.
Below in conjunction with drawings and Examples the present invention is further described.
Referring to Fig. 1, this figure is the flow chart of the pipe tobacco separation method in the tobacco leaf dedusting system of machine for cutting of the present invention, may further comprise the steps:
S101, obtain the actual wind speed in the cleaning shaft.
Specifically can detect wind speed in the cleaning shaft, when this wind speed remains on reasonable range, tobacco leaf, pipe tobacco are separated by air velocity transducer.Especially, obtaining the many places wind speed in the cleaning shaft, is actual wind speed in the cleaning shaft with its mean value, to reduce departure.
S102, whether judge actual wind speed greater than first target wind speed, described first target wind speed is for just siphoning away the minimum wind force of pipe tobacco;
If enter step S103;
If not, enter step S104.
S103, output first control signal reduce the valve opening of cleaning shaft according to this first control signal.
After the valve opening of cleaning shaft reduced, exhaust air rate reduced, wind speed reduces, and made pipe tobacco fall, and realized separating with flue dust.
S104, whether judge actual wind speed less than second target wind speed, described second target wind speed is for just siphoning away the minimum wind force of flue dust;
If enter step S105;
If not, return step S101.
S105, output second control signal, according to this second control signal increase cleaning shaft valve opening.
After the valve opening of cleaning shaft increased, exhaust air rate strengthened, wind speed increases, and makes flue dust be sucked away, and realized that pipe tobacco, flue dust separate.
For the physical parameter of different pipe tobaccos, flue dust, first target wind speed and described second target wind speed be difference to some extent, at this moment, can detect pipe tobacco and flue dust parameter in advance, obtains described first target wind speed and described second target wind speed, guarantees the accurate of control procedure.
Thus, the wind speed in the cleaning shaft remains between first target wind speed and second target wind speed, and pipe tobacco and flue dust are separated.Pipe tobacco can further be recycled after separating, and realizes the maximum utilization of resource.
Referring to Fig. 2, this figure is the block diagram of the pipe tobacco separator in the tobacco leaf dedusting system of machine for cutting of the present invention, comprising:
Some air velocity transducers 4 are arranged in the cleaning shaft 5, are used to detect and export the wind velocity signal in the cleaning shaft 5.Preferably, air velocity transducer 4 is temperature-sensitive wind speed probe, is particularly suitable for surveying in the pipeline wind.In addition, air velocity transducer 4 is a plurality of, with each air velocity transducer 4 detect and the wind velocity signal mean value of output as the actual wind speed in the cleaning shaft 5.
Input block 1 is used for writing first echo signal, second target wind speed etc. to controller 3 and controls parameters.
Therefore for different tobacco and dust, can detect pipe tobacco and flue dust parameter in advance, obtain after described first echo signal, second target wind speed writing controller 3 again, can revise the control parameter of controller 3 thus easily.
Only be preferred implementation of the present invention below, should be pointed out that above-mentioned preferred implementation should not be considered as limitation of the present invention, protection scope of the present invention should be as the criterion with claim institute restricted portion.For those skilled in the art, without departing from the spirit and scope of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
