Abstract
The present invention relates to the blowing technology for eliminating non-tobacco impurities, particularly to a technology link for eliminating the non-tobacco impurities between a first moistening procedure and a second moistening procedure in the technology process of redrying tobacco. The present invention is orderly provided with a narrow conveying belt (2), a disc distributor (3), a high-speed conveying belt (4) and a wind classifier (5) behind a sand sieving drum (1), wherein the disc distributor (3) comprises two symmetrical discs which are rotated in opposite direction; the wind classifier comprises a wind classifying chamber (6), a fan (7), a wind pipe (8), a feed inlet (9), a discharge outlet (10) and an impurity discharging opening (11). The present invention is the wind classification technology of non-tobacco impurities, which has the advantages of high production efficiency, less investment, simple maintenance and high impurity eliminating efficiency.
Description
Technical field
The non-cigarettes, wines and miscellaneous goods thing that the invention belongs to cigarette fiber tow production and tobacco redrying production and processing technology is rejected the process procedure technical field.
Background technology
Because non-cigarettes, wines and miscellaneous goods thing can produce the assorted gas of excitant in smoking property of cigarette, and flammability is poor, resistance to suction is big, cigarette product is produced harm, even the toxic gas that produces because of the polyethylene kind substance combustion liability to pay compensation that causes the actual bodily harm to the consumer to cause, have a strong impact on the prestige of cigarette product and manufacturing enterprise.It is the non-metal kind foreign material that present non-cigarettes, wines and miscellaneous goods owner wants difficult point, because the physical behavior of these class foreign material is comparatively similar to tobacco leaf, does not still have equipment so far and can effectively it be separated from tobacco leaf, and what adopt substantially is that the hand picking method is separated.Be difficult to satisfy the large-scale industrial production needs and manually separate non-cigarettes, wines and miscellaneous goods thing, efficient is extremely low, and the rejecting rate is lower, has been difficult to adapt to the production technology demand of tobacco product now.In recent years begin to adopt the spectrum impurity removing technology abroad, the separating substances that color and tobacco leaf differ bigger is come out, but the foreign material little to aberration are then powerless, and the investment of spectrum impurity removing equipment is big, technical sophistication, difficult in maintenance.
Summary of the invention
The objective of the invention is provides a kind of small investment for the weak point that overcomes above-mentioned prior art existence, safeguards simply the non-cigarettes, wines and miscellaneous goods thing selection by winnowing remover apparatus that dust removal rate is high.
The objective of the invention is to realize by following technical solution.
Behind sieve sand tube, be disposed with: conveyer belt and round tray cloth glassware and high-speed conveyer belt and air classifier; Wherein, the round tray cloth glassware is two symmetrical reverse rotating circular disks; Air classifier includes air separating bin, blower fan, airduct, charging aperture, discharging opening and impurity discharging port.
The present invention also is provided with a material casting roller on the conveyer belt top, and is provided with a ribbon conveyer between round tray cloth glassware and high-speed conveyer belt; On the motor of high-speed conveyer belt, also be provided with arrangements for speed regulation; And be provided with a material casting roller at the head end of high-speed conveyer belt.
Because the physical characteristic of non-cigarettes, wines and miscellaneous goods thing is similar to the fragment tobacco leaf, adopt drainage wind branch principle itself and most of complete tobacco leaf can be separated.Its technical process be the material that will come out from the sand tube by conveyer belt by the round tray cloth glassware with its draw thin, cloth is wide, make it loose, be evenly distributed on the high-speed conveyer belt charging aperture that enters air classifier by charging aperture and be thrown into air separating bin, heavier tobacco leaf falls to discharging opening and is sent to next procedure under the effect of blower fan wind-force, and lighter crumbled tobacco foreign material are blown to import again after hand picking on low flow velocity belt to impurity discharging port by wind-force and enter next procedure in the major ingredient.
Further set forth content of the present invention below in conjunction with Figure of description and embodiment.
Description of drawings
Fig. 1 is an embodiment of the invention schematic flow sheet;
Fig. 2 is the apparatus arrangement schematic diagram of Fig. 1.
The specific embodiment
Because of about the thicker about 80mm of material thickness that transports by narrow conveyer belt 2 from sieve sand tube 1, be provided with a material casting roller 12 on narrow conveyer belt 2 tops and shed material for satisfying the selection by winnowing condition, adopt the round tray cloth glassware 3 of pair of discs symmetrical reverse rotation material to be drawn thin simultaneously, cloth is wide, make material loosening, place on the ribbon conveyer 13 of broad equably, make material thickness greatly about about 20mm.Deliver to then on the high speed belt conveyer 4, high speed belt conveyer 4 is provided with arrangements for speed regulation, adapting to the variation of mass flow, also be provided with a material casting roller 14 at the head end of high speed belt conveyer 4 and enter material loosening that air classifier 5 cavitys partly are air separating bin 6, uniform to impel from charging aperture 9.Air classifier 5 is a mature equipment on the present structure, there is multiple model to choose, what present embodiment was chosen is closed-loop path formula air classifier, this air classifier has two symmetrically arranged blower fans 7, airduct 8 by the closed-loop path structure is sent to air separating bin 6 with wind, how many rotating speed of blower fan 7 and air outputs are generally determined according to dust diameter and air separating bin size and material, the air quantity of being regulated can drop down onto discharging opening 10 smoothly with the complete substantially tobacco leaf of complete sum, but not cigarettes, wines and miscellaneous goods thing and more broken tobacco leaf then by wind to impurity discharging port 11, the tobacco leaf that complete sum is complete is substantially delivered to next process 15 through the conveyer belt that discharging opening 11 is set at interface.Non-cigarettes, wines and miscellaneous goods thing that comes out by impurity discharging port and crumbled tobacco then by drop down onto a speed more slowly ribbon conveyer after the artificial hand inspection, import again again and enter next process 15 in the major ingredient.
Pneumatic separator of the present invention is applicable to the front-end process in the cigarette throwing too.
