The specific embodiment
As shown in Figure 1, the utility model comprises supplied materials belt conveyor, be positioned at the tobacco stalk straightening screening plant after belt conveyor and be positioned at the drawing mechanism below screening plant: described tobacco stalk straightening screening plant is divided into the upper, middle and lower-ranking sieve 1,2,3 that shakes, wherein go up, in two-layer shake sieve 1,2 each by two sections, form, sieve 1 and intermediate layer sieve 2 the screen cloth cross section that shakes that shakes, upper strata is variform waveform, and sieve 3 shakes for the flat board groove that shakes in lower floor.
Upper strata shake sieve 1 shape of cross section be waveform, divide two sections of front and back, as shown in Figure 4, leading portion screen cloth 11 cross sections are uniform wave-likes, such as sine curve, the offal of being convenient to arrange is in a jumble adjusted gradually direction in vibrating transportation process, and length arragement direction is consistent with mass transport direction, and falls in trough groove; As shown in Figure 5, back segment screen cloth 12 cross sections are wave-likes wide under upper point, the crest ratio of wave is compared with sharp and trough is wider, or crest is narrow and trough is wider, also can be connected " U " shape in front and back, the offal that assurance is made in order direction in trough groove remains unchanged, and also can not jump in other wave.。
Upper strata shake sieve 1 on sieve aperture comprise circular port section 8 and rectangular opening section 9, as shown in Figure 2, circular port section 8 and rectangular opening section 9 intervals are arranged alternately, or after a circular port section 8, establish two rectangular opening sections 9 as required, and then are circular port section 8.Circular port section 8 is distributed with the circular aperture 4 of 1.5mm-5mm, and it is 0.5cm-5cm that rectangular opening section 9 is distributed with length, the rectangular opening that width is 2mm-5mm, and circular aperture 4 and rectangular opening 5 are mesh; Rectangular opening 5 length direction consistent with material movement direction, like this can be so that thin stalk more easily falls from rectangular opening 5.
As shown in Figure 3,4, sieve 2 the screen cloth cross section that shakes, intermediate layer is variform waveform or flat board, if employing waveform, as shown in Figure 4,5, same leading portion screen cloth 11 is uniform wave-likes, back segment screen cloth 12 cross sections are wave-likes wide under upper point, and the intermediate layer sieve that shakes 2 is provided with a plurality of circular port sections 8, and circular port section 8 is similarly circular aperture 4 or the slotted eye of diameter 1.5mm-5mm.Between two sections of circular port sections 8, can be to be provided with certain intervals, also can not establish interval, directly be connected.Shake circular port section 8 or rectangular opening section 9 positions of sieve 1 of sieve 2 circular port section 8 positions and its upper strata, top that shake, intermediate layer are corresponding, and width is also corresponding, and the broken stalk under the sieve 1 that can better upper strata be shaken sieves sifts out.
Sieve 3 shakes for the flat board groove that shakes in lower floor.
Discharging gathering-device is positioned at the tobacco stalk straightening screening plant back lower place, discharging gathering-device comprises normal stalk conveying device 10, carefully obstructs collector 6 or carefully obstruct conveying device, broken stalk collector 7, thin stalk collector 6 or carefully obstruct conveying device and be located at the shake exit of sieve 2, intermediate layer, broken stalk collector 7 is located at the shake exit of sieve 3 of lower floor.
Offal before expanding or after expanding is delivered to tobacco stalk straightening screening plant by belt conveyor, and under the vibration of equipment, offal moves on corrugated upper strata shakes sieve 1, and vibration falls into corrugated groove position gradually, and offal is arranged along flow direction of material; Through shake sieve 1 o'clock of upper strata, broken stalk can fall into circular aperture 4 simultaneously, enters the intermediate layer sieve 2 that shakes, and through regrading, falls into lower floor's sieve 3 that shakes, and delivers into broken stalk collector 7; Thin stalk upper strata shake that sieve 1 is carried and vibration under, by rectangular opening 5, drop down onto the intermediate layer sieve 2 that shakes, be delivered to the shake outlet of sieve 2 of intermediate layer, fall into thin stalk collector 6 or enter thin stalk conveying device.
When the utility model is processed for the sieve classification of former stalk, be placed on before cabo expansion or moisture regain, broken stalk can be sieved out and does other purposes, to normally obstruct and carefully obstruct sieve classification and carry out grouping Processing, adopt different moisture regain modes, moisture regain parameter to process, to improve the moisture regain quality of moisture regain efficiency and different size offal;
The utility model can be used for two kinds of techniques:
1, the utility model can be used for the offal processing technology of " cabo expansion---moisture regain---is cut stem ".Be divided into again two kinds of situations: before (1) the utility model gets damp again after being placed on and expanding, the mesh size of device adopts large-size, sifts out broken stalk, by elongated stalk and the thick stalk classification of different size after expanding, adopt different moisture regain PROCESS FOR TREATMENT, improve moisture regain efficiency and moisture regain quality; (2) the utility model is placed on expanded cabo and cuts before stem, sift out broken stalk, by elongated stalk and the thick stalk classification of different size after expanding, improve the uniformity of cutting stem supplied materials, then adopt the different stem parameter processing of classifying of cutting, can reduce the generation of running stalk, stalk head and broken end, improve homogeneity of stalk shreds, improve and cut stem quality.
2, the utility model can be used for the offal processing technology of " regaining moisture of cabo---is cut stem---, and stem expands ".The utility model is placed on to be cut before stem, can be by the thin stalk after moisture regain and the offal classification of normal size, improve the uniformity of cutting stem supplied materials, then adopt difference to cut the processing of classifying of stem parameter, can reduce the generation of running stalk, stalk head and broken end, improve homogeneity of stalk shreds, improve and cut stem quality.
The utility model is used for cutting before stem, and the upper strata of making screening plant in order sieve 1, the intermediate layer sieve 3 that shakes that shakes adopts the waveforms sieve that shakes, and by tobacco stalk straightening, can improve the uniformity of cutting stem size.
Before the selective basis sieve classification of the mesh size of screen cloth, raw materials size is determined.This device, for the processing of former stalk, is placed on before cabo expansion or moisture regain, and mesh can adopt reduced size; This device is for after cabo expansion, after moisture regain or before chopping, and mesh adopts large-size.
