The structure of the tobacco leaf vibration screening device of the specific embodiment of the utility model one is carried out below according to Fig. 3 to Fig. 7
Describe in detail.
As shown in figure 3, the tobacco leaf vibration screening device of the present embodiment includes three-level screening structure, respectively in short transverse
On set gradually first screening structure 1, second sieve structure 2 and the 3rd sieve structure 3.Wherein, the sieve of the first screening structure 1
The equivalent diameter in hole is 12mm, and the equivalent diameter of the sieve aperture of the second screening structure 2 be 6mm, the 3rd sieve the sieve aperture of structure 3 etc.
Imitate a diameter of 2mm.Compared with prior art, it is only necessary to increase one-level 12mm the first screening structure on the basis of original device,
Change is smaller, is easy to promote the use of in production practices.
It is as shown in Figure 4 that the tobacco leaf vibration screening device of the present embodiment carries out tobacco leaf screening idiographic flow.Tobacco leaf is from feeding end I
Progress one-level screening in the first screening structure 1 is fallen into, now tobacco leaf of the diameter more than 12mm is directly in the upper of the first screening structure 1
Surface, which is conveyed and enters roller from discharging opening I, carries out Ordering and casing.And tobacco leaf of the diameter less than 12mm falls into the second screening
Two level screening is carried out in structure 2, now, tobacco leaf of the diameter more than 6mm also enters roller from discharge end O and carries out Ordering and casing, and
Tobacco leaf of the diameter less than 6mm then drops into the 3rd screening structure 03 and carries out three-level screening, and now, diameter is more than 2mm tobacco leaf
Storage leaf is directly entered, and tobacco leaf of the diameter less than 2mm is discharged to dust pelletizing system from waste material end R.The tobacco leaf vibratory sieve of the present embodiment
Separating device is first sieved 12mm tobacco leaf, the screening pressure of the second screening structure is reduced, so as to improve screening efficiency.
Preferably, the depth direction of the sieve aperture of the first screening structure 1 of the present embodiment and tobacco leaf conveying direction are at an acute angle.
Specifically, as shown in figure 5, the first screening structure 1 of the present embodiment includes venetian blind type structure.
First screening structure includes framework 11 and the multiple plates 12 being arranged at intervals in framework 11.Phase in multiple plates 12
The distance between two adjacent plates 12 are 12mm.When tobacco leaf flows through the first screening structure of venetian blind type structure, tobacco leaf exists
In being constantly fed forward by plate effect of vibration repeatedly and with seething motion, by the fragment being mingled with tobacco leaf and powder with
Large stretch of tobacco leaf is separated, and under fall in the second screening structure, and most of tobacco leaf can be from the upper of venetian blind type structure
Side transfers out, and screening efficiency significantly improves., can be with and the sieve aperture of the first screening structure of venetian blind type structure is obliquely installed
Reduce the blocking of sieve aperture.
As shown in Figure 6 and Figure 7, the second screening structure 2 of the present embodiment includes the sieve plate 21 with opening, is respectively arranged at
The first end of the first convex wall 22 and the second convex wall 23 of sieve plate both sides about 21, the first end of the first convex wall and the second convex wall is along cigarette
Leaf conveying direction is respectively arranged at the both ends of opening, the second end of the first convex wall and the second end of the second convex wall be free end and
Extend to the middle part of opening, the passage between the first convex wall and the second convex wall forms the sieve aperture of the second screening structure.So set
The depth direction for putting the sieve aperture for causing the second screening structure 2 is inverse logistics direction, alleviates supplied materials side of the sieve aperture directly with tobacco leaf
The problem of to relative and caused sieve pore blockade.And first convex wall tobacco leaf convey during can stir tobacco leaf, and then
Play a part of preventing from blocking sieve aperture.
Preferably, the first convex wall and the second convex wall are the conical surface.First convex wall and the second convex wall are arranged to the conical surface and cause
The face that one convex wall and the second convex wall contact with tobacco leaf is smooth, tobacco leaf clamping stagnation or indwelling is prevented in convex wall, beneficial to the screening of tobacco leaf.
Specifically in the present embodiment, the effective diameter of the sieve aperture of the second screening structure is 6mm.
As shown in figure 3, the tobacco leaf vibration screening device of the present embodiment also includes the 3rd screening structure 3.The of the present embodiment
The powder of three screening structures is smaller and loose, and the risk that adhesion blocks, therefore the 3rd sieve of the present embodiment will not be produced to sieve aperture
Separation structure uses the structure of common stamped sieve.
Original two-stage screening structure optimization is that three-level sieves structure, increase by the tobacco leaf vibration screening device of the present embodiment
The contact area of tobacco leaf and screening structure simultaneously extends the passage time of tobacco leaf, is effectively improved the problem of tobacco leaf blocks sieve aperture.And
Tobacco dust showed increased under sieve, lifts the screening efficiency of tobacco cutting, and effectively alleviation powder, which enters in subsequent handling, causes
Barrel sizing, reduce the loss of tobacco leaf.
Applicant of the present utility model vibrates to the tobacco leaf vibration screening device of the present embodiment and tobacco leaf of the prior art
Screening plant has carried out online sieve test.Tobacco leaf vibration screening device of the prior art puts into tobacco leaf 2298.62kg, screening
Go out 29.58kg, screen rate 1.3%.And the tobacco leaf vibration screening device input 2202.41kg of the present embodiment, screen out
41.52kg, screen rate 1.9%, sieving capacity significantly improves.
Finally it should be noted that：Above example is only illustrating the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
Understand：Specific embodiment of the present utility model can still be modified or some technical characteristics are equally replaced
Change；Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model
Among scope.
