According to the invention, the different sieves at different layers are used for effectively separating cabo heads, overlong stems, long stems, short stems, crushed stems and smashed pieces of the stemmed caboes subjected to threshing and redrying, and accordingly, the cabo specification is uniform, which can more meet the requirements of tobacco primary process procedures, and facilitate classification packaging, storage and transportation of the caboes.
Description
Technical field
The invention belongs to the tobacco processing equipment technical field, be specifically related to a kind of offal Multi-stage refined screening plant that can separate respectively the different shape offal materials such as stalk head, broken stalk, length stalk, stalk foam.
Background technology
Compare with tobacco leaf, the offal tar content is lower, and its physical arrangement and tobacco leaf approach, and it is strong, with low cost to hold fiery ability.During the tradition tobacco produced, offal was used as usually that waste material processes.In order to adapt to the development trend of " lowering harm and decreasing coking ", usually can add tobacco stalk raw material in the present production of cigarettes.For this reason, how to process offal, make it more can adapt to the study hotspot that tobacco produces becomes tobacco business.Domestic redrying enterprise, process usually only this specifications parameter of 20mm for offal, namely＞20mm is above to be long offal, existing cabo sifting equipment designs based on this, only is provided with two-layer screen cloth, is used for screening length stalk and broken stalk, broken foam, the screen cloth specification is simply single on the one hand, do not have further refinement cabo sifting specification, effectively eliminating stems head, long stalk etc. are unfavorable for the material of offal following process, the uniformity coefficient of offal after the impact screening; The chopping equipment that adopts of present domestic cigarette enterprise all adopts inch for designing on the basis all from abroad on the other hand, and the offal screen cloth that uses does not at present all carry out screen cloth length with inch as standard and obstructs screen designs; While, the short stalk of part can directly fall into broken stalk groove owing to present short stalk screen cloth use is metal knitted square screen cloth, caused packing offal degree of purity relatively poor, made the rear offal of packing of screening can not well adapt to follow-up stem production.For this reason, develop a kind of offal Multi-stage refined screening plant that can separate respectively the different shape offal materials such as stalk head, broken stalk, length stalk, stalk foam, be very important for taking full advantage of of offal.
Summary of the invention
The object of the present invention is to provide the offal Multi-stage refined screening plant of the different shape offal materials such as a kind of energy separated in synchronization stalk head, long stalk, broken stalk, length stalk, stalk foam.
The object of the present invention is achieved like this, comprises screening drive unit, charging aperture, particle outlet, sieve tool, and the screening drive unit drives the sieve tool; Bar comb shape sieve tool, square hole screen tool, oval slotted hole sieve tool, the round-hole mesh tool of described sieve tool for setting gradually from high to low, the sieve tool comprises baffle plate, screen cloth and oversize outlet; The screen cloth of the corresponding bar comb of charging aperture shape sieve tool, the screen cloth of the screen cloth counterparty hole sizer tool of bar comb shape sieve tool; The corresponding particle feeder of the screen cloth of square hole screen tool, its oversize export the screen cloth of corresponding oval slotted hole sieve tool; The screen cloth of the screen cloth corresponding circle hole sizer tool of oval slotted hole sieve tool, the corresponding particle feeder of the screen cloth of round-hole mesh tool.
Layering of the present invention arranges different sieve tools, the stalk head of the offal to beating and double roasting, after going to obstruct, long stalk (＞101.6mm), long stalk, short stalk, broken stalk, broken foam effective separation sieve, improve and beat the long stalk of flue-cured tobacco stalk screening efficiency, in the situation that guarantee big-and-middle qualification rate, effectively promote long stalk screening efficiency, the uniform specification of offal has more easily satisfied the needs of silk producing procedures, is convenient to offal class wrapping, storage and transportation.

Operation principle of the present invention:
The cabo sifting of prior art adopts secondary sieve tool, often is mixed with the stalk head in the tobacco stalk raw material that sifts out, long stalk content is high, the uniformity is not good.The level Four sieve tool that layering of the present invention arranges, the offal refinement screening of the different size after respectively beating and double roasting being gone to obstruct.As shown in Figure 4, the sieve tool of one-level screening is bar comb shape screen cloth, and bar comb shape screen cloth is according to offal stalk head and long stalk size design, can effectively sieve rejecting to stalk head and long stalk, reduce the quantity of such offal in finished product, for stalk throwing provides quality raw materials.As shown in Figure 5, the sieve tool of secondary screening is square-mesh screen, arranges in order to screen out broken stalk, reduces broken stalk and sneaks in the next stage material.As shown in Figure 6, the sieve tool of three grades of screenings is oval slotted hole screen cloth, adopts the sieve aperture of 3 ~ 5mm * 20 ~ 32mm, is convenient to the offal sieve that meets need of production (length) lower; The most Recipe leaf beatings that adopt of present beating and double roasting, to beat the tobacco leaf of different parts, grade is mixed, offal had different after offal was processed owing to the position is different after beating, in order to adapt to this situation, adopt the sieve aperture (adapting to respectively top offal and middle and lower part offal) of two kinds of specifications, can be better the offal of required specification be sieved.As shown in Figure 7, the sieve tool of level Four screening is the circular hole screen cloth, can further sift out broken stalk, and the circular hole that is stamped to form can reduce short stalk and be sifted out, and improves the utilization rate of raw material.
The course of work of the present invention:
Offal after beating and double roasting goes to obstruct enters bar comb shape sieve tool 5 through charging aperture 1, and stalk head, long stalk are separated out, stay above the screen cloth by grid section, isolates through the oversize outlet 3 of bar comb shape sieve tool 5, and other offal materials enter the screen cloth of square hole screen tool 6 through grid section; Broken stalk falls into particle feeder 4 through the sifting out of square hole screen tool 6 in the offal material, and other offal materials are stayed above the screen cloth, through square hole screen tool 6 oversize outlet 3 enter the screen cloth of oval slotted hole sieve tool 7; The on-the-sieve material of oval slotted hole sieve tool 7 is the offal that meets the production length requirement, sends into gathering-device through the oversize outlet 3 of oval slotted hole sieve tool 7, and oval slotted hole sieve tool 7 undersize materials fall into the long stalk that round-hole mesh tool 8(also has minute quantity and fall into); Through 8 screenings of round-hole mesh tool, broken stalk and broken end fall into particle feeder 4, and the on-the-sieve material of round-hole mesh tool 8 is sent into gathering-device through oversize outlet 3 and gone out (being similarly qualified offal material).
