Description
Technical field
The utility model relates to the removal of impurities of tobacco business cut tobacco more particularly to a kind of selection by winnowing trash separators for tobacco cut tobacco.
Background technique
In tobacco business, tobacco leaf production workshop requires to add flexible pneumatic separator after drying silk according to processing quality.In order to
It realizes to the Effective selection and flexible delivery of the material containing sundries, skill is separated with the tobacco flexibility for selecting principle to combine of floaing using flotation
Art is effectively reduced the production cost of cigarette to improve the product quality of cigarette.
Flexible isolation technics passes through flexible pneumatic separator and realizes, flexible pneumatic separator includes cabinet, and cabinet is equipped with charging
Mouth, impurity removal bucket and conveyer belt, feeding mechanism side and impurity removal bucket side are respectively equipped with air door, and cabinet is connected by air hose and dedusting room
Logical, be mounted on winnowing machine on air hose and control total air door intake volume, basic principle is: sorted materials assign one by feeding mechanism
Determine freely to fall after initial velocity is sent into cabinet, side air admission identical with material direction once floats to material during this
Choosing, the relatively large substance of density such as wet mass pipe tobacco, stalk label and a shape stalk grain are fallen into float tank, by vertically enter the wind to its into
Row secondary flotation, by floaing, floating selection by winnowing, larger (unqualified) material of density twice fallen by float tank lower exit port, conjunction
Lattice pipe tobacco sends out cabinet by conveying mechanism, and powder dust then passes through sieve and is pumped by air hose, and passes through quilt after peculiar odor treatment
It is discharged in atmosphere.
It finds, because air door is without adjustment benchmark, effectively wind speed can not be detected in use in use

Specific embodiment
Structure depicted in Figure of description, ratio, size etc., only to cooperate the revealed content of specification, with
Understand for those skilled in the art and read, is not intended to limit the utility model enforceable qualifications, therefore does not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the utility model institute
Under the effect of capable of generating and the purpose that can reach, the model that the revealed technology contents of the utility model can be covered should all be fallen in
In enclosing.Meanwhile cited such as "upper", "lower", "front", "rear", " centre " term in this specification, it is merely convenient to describe
Be illustrated, rather than to limit the enforceable range of the utility model, relativeness is altered or modified, without substantive change
Under technology contents, when being also considered as the enforceable scope of the utility model.
As Figure 1-Figure 2, the utility model is a kind of tobacco cut tobacco selection by winnowing trash separator, including cabinet 1, is set on cabinet 1
There are feeding mechanism 11, impurity removal bucket 12 and conveyer belt 13,11 side of feeding mechanism and 12 side of impurity removal bucket are respectively equipped with air door, described
Cabinet 1 is connected to by air hose 2 with dedusting room；It further include testing agency, testing agency includes differential pressure indicator 3, and the differential pressure indicator 3 is equipped with
High voltage interface 31 and low-voltage interface 32, high voltage interface 31 connects with by the first pipeline 4 with detector 5, low-voltage interface 32 with greatly
Gas connection, the detector 5 are located in the air hose 2, and the detector 5 is also connect with the second pipeline 6, second pipeline 6
It is connected to compressed air source.Valve 7 is respectively equipped on first pipeline 4 and the second pipeline 6.
The selection of differential pressure indicator 3 selects to determine according to such as under type in the utility model, i.e., is obtained according to Bernoulli equation
Wind-pressure relationship, the dynamic pressure of wind are as follows:
Wp=0.5rov2
Wherein wp is wind pressure [kN/m2], ro is atmospheric density [kg/m3], v is wind speed [m].Due to atmospheric density (ro) and
The relationship of severe (r) is r=rog, therefore has ro=r/g.Also it can obtain:
Wp=0.5rv2/g。
This formula is standard wind pressure formula, in normal conditions (air pressure 1013hPa, temperature are 15 DEG C), air severe r=
0.01225[kN/m3].Latitude is the gravity acceleration g=9.8 [m/s at 45 °2],
Obtain wp=v2/1600
Wp=0.176 [kN/m3]=176pa
Therefore, 3 selected range of pressure gauge is the mechanical differential pressure indicator of ± 250pa.
In the operating condition, with reference to Fig. 1 and its arrow direction, air hose 2 makes generation in cabinet 1 negative by winnowing machine air-breathing
Pressure, the air door of 12 side of 11 side of feeding mechanism and impurity removal bucket generate wind under the action of negative pressure, and cut tobacco is assigned by feeding mechanism 11
It gives after certain initial velocity is sent into cabinet 1 and freely falling, during this, the air door of 11 side of feeding mechanism is generated and feedstock direction phase
For same wind to dispel cut tobacco, the primary choosing of floaing of progress, the relatively large wet mass cut tobacco of density, stalk label and shape obstruct the impurity such as grain to out
Miscellaneous bucket 12 is fallen, and the air door of 12 side of impurity removal bucket carries out secondary flotation for it to up-draught, by floaing, floats selection by winnowing twice, close
It spends larger (unqualified) impurity to be discharged from impurity removal bucket 12, qualified cut tobacco sends out cabinet 1 by conveyer belt 13, and powder dust then passes through
Air hose 2 is pumped, and by being discharged in atmosphere after peculiar odor treatment.
During the work time, the valve 7 on the first pipeline 4 is opened, and the valve 7 on the second pipeline 6 is closed, and differential pressure indicator 3 is logical
5 measuring wind speed in real time of detector is crossed, according to the size of wind speed, adjusts the power of winnowing machine, and then the air quantity for adjusting air hose 2 is big
It is small.The valve 7 on the first pipeline 4 is closed before it need to clean to detector 5, is protected differential pressure indicator 3 not to be hit, is then opened
Cleaning is blowed to detector 5 in valve 7 on second pipeline 6, compressed air.
In actual use, when negative pressure value is adjusted to -140pa or less in cabinet, selection by winnowing is rejected rate containing silk in object stalk and is accounted for
Than significantly improving, reaches 30% or so, do not meet technique requirement, cause the waste of material；It even will cause wind lower than -120pa
Machine is selected to block.When negative pressure value is adjusted to -170pa or more, although selection by winnowing is rejected in object stalk, the accounting of rate containing silk is low, and cut tobacco is done
Moisture difference reaches 1.0 between the two for dry moisture content and the cut tobacco selection by winnowing index of aridity, and moisture content scatters and disappears big；Therefore, negative pressure value -140 is chosen
~-160pa is as adjustment section.
As shown in Figure 1, being equipped with comb roll dies 121 in the impurity removal bucket 12.
As shown in Figure 1, the air hose 2 is mounted on the top of cabinet 1 in order to make overall structure more reasonable.
As shown in Figure 1, being cased with porous protective cover outside the detector 4.
In conclusion the utility model is used for the selection by winnowing trash separator of tobacco cut tobacco, in the prior art one is effectively overcome
A little practical problems are to have very high utility value and use meaning.
Above embodiment is only illustrative of the principle and efficacy of the utility model, and not for limitation, this is practical new
Type.The utility model can be improved there are many more aspect under the premise of without prejudice to overall thought, for being familiar with this technology
Personage can all be carried out modifications and changes to above-described embodiment under the spirit and scope without prejudice to the utility model.Therefore,
Such as those of ordinary skill in the art is in spirit revealed without departing from the utility model and institute under technical idea
All equivalent modifications or change completed, should be covered by the claim of the utility model.
