The specific embodiment
Feature based on leftover bits and pieces, inventor thinks and is necessary that the source to leftover bits and pieces describes, and especially how to obtain and the proterties of the leftover bits and pieces that obtains describes.
With reference to Figure of description 1, it is the structure principle chart of current conventional a kind of cottonseed stripping cotton lint production line, the arrow of top represents to collect suede blower fan 6 to the direction of cyclone dust collectors 7 convey materials, and the material that cottonseed stripping cotton lint production line has determined to enter cyclone dust collectors has the equipment of what character feature.
Correspondingly, corresponding cottonseed stripping cotton lint production line associated production flow process comprises the following steps:
A) on stripping suede production line: cottonseed distribution auger 1 is assigned to cottonseed on corresponding delinter 2 shells suede, isolate cottonseed and the short flannel mixture with the first feature, the short flannel mixture of this first feature comprises dust and short flannel, and dust wherein is here understood as should separated foreign material in conventional dust and other short flannel.
This step completes in delinter 2, and delinter has many conventionally, and this above delinter, is provided with cottonseed storage case and cottonseed distributes auger 1, and cottonseed is assigned in each delinter equably, by delinter, according to the stripping suede in conventional Yi Er tri-roads, sequentially shells suede.
The short flannel mixture with the first feature being stripped from is admitted to collection suede machine 4: in Fig. 1, between delinter 2 and collection suede machine 4, be connected with pipeline, collect between the blower fan for air inducing (the collection suede blower fan of Fig. 1) air inlet of suede machine inlet scoop and configuration simultaneously and be also connected with air-suction duct, by wind-force, short flannel is adsorbed on the dust cage wire side by the collection suede machine rotation of wind-force effect, then by the short flannel of dialing of the brushing roller on collection suede machine, this short flannel is cleared up and packed.
The passage that the wind-force tube road that blower fan produces connects acts on again collection suede machine dust cage wire side, having dust and short suede is inhaled into via the mesh of dust cage wire side, then between the outlet of blower fan and cyclone dust collectors 7, there is pipeline to be connected, the mixture (main component is shorter short flannel, dust and air) of the second feature that collection suede machine 4 is produced is blown in cyclone dust collectors, forms leftover bits and pieces and enters the follow-up cleaning of cyclone dust collectors leftover bits and pieces and recovery process.
In the stripping suede stage before, the cottonseed that proportion is larger falls into drag conveyor 3 and is transported to appointed area.
In addition, those skilled in the art can be with reference to following content: delinter 2 seed feeding rollers are under the driving of variable frequency reducer motor, cottonseed feeding is equipped with on the seed dripping plate of magnet arrangement, assorted being adsorbed on seed dripping plate of iron in cottonseed manually cleaned out, cottonseed enters working box by self gravitation, the larger impurity of proportion wherein follows cottonseed together separated conventionally, there will not be in the cyclone dust removal stage.
The cottonseed drive of seed-poking roller and hook of saw blade in working box draw effect, form the cottonseed volume of rotation, because cottonseed volume is different with saw blade rotating speed, form like this linear speed poor, are beneficial to shell suede.The short flannel being drawn by sawtooth hook is sucked collection suede machine by the gap of rib row by wind-force, gap, rib row operating point is 3mm ~ 3.3mm, cottonseed waist footpath is generally the 5mm of 5 mm ~ 7., because cottonseed waist footpath is greater than the gap of rib row, cottonseed is stopped by rib row in the hook of sawtooth is pulled through journey, make it that adhesion in cottonseed volume reduces and in drag conveyor below rib row drops to delinter naturally, be transported to the region of appointment, also relate to the separation of the larger thing of proportion here.Above step mostly is conventionally known to one of skill in the art.
So further reclaim, be just embodied in the processing after the cyclone dust removal stage of the present invention.
Short flannel collects and clears up: in accompanying drawing 2, the blast pipe in left side, the top of cyclone dust collectors 7 connects the blast pipe of collection suede blower fan 6, for receiving the main mixture being comprised of short flannel, dust and air of the second feature; The passage that has iron sheet to make between collection suede machine 4 and short flannel descaling machine 5 is connected, and the short flannel after stripping suede relies on the wind-force effect in pipeline to be adsorbed on dust cage wire side, and by dialing of its fuzz-peeling machine, short flannel is fed in short flannel descaling machine and is cleared up.
Collecting of leftover bits and pieces: the air outlet of collection suede blower fan 6 is connected by pipeline with the air inlet of cyclone dust collectors 7, the impurity discharging port of cyclone dust collectors 7 bottoms is connected with Impurity Diffusion case, Impurity Diffusion lower box part is connected with ∮ 200mm ~ ∮ 250mm helical feed auger, is less than mixture that the short flannel of 3mm and dust forms and by pipeline, by linear velocity, is not less than centrifugal force that the draught fan impeller rotating speed of 60 m/s produces in the lump and enters into cyclone dust collectors with the speed of 12 m/s ~ 18 m/s.Heavy impurity drops into the Impurity Diffusion case being connected with cyclone dust collectors impurity discharging port, and formation the present invention leftover bits and pieces to be dealt with, then falls into helical feed auger, air from the exhaust outlet on cyclone dust collectors 7 tops discharged to atmosphere.
There is above description known, the ventilative amount absorption delinter sawtooth of the dust cage net that wind-force is rotating by collection suede machine 4 is scraped the short flannel of stripping, while also easily length is less than to the short flannel of 3mm and the leftover bits and pieces of dust composition enters collection suede blower fan 6 by pipeline in the lump, and then under the effect of draught fan impeller centrifugal force, the speed with 12 m/s ~ 18 m/s enters into cyclone dust collectors.Leftover bits and pieces in cyclone dust collectors along top-down spiral motion, heavy impurity drops into Impurity Diffusion case, area sudden enlargement due to diffusion chamber, cause the speed of impurity to decline suddenly, by self gravitation, land and collect in helical feed auger, air from the exhaust outlet on cyclone dust collectors top discharged to atmosphere.
The basic characteristics of the leftover bits and pieces obtaining according to said method are, contain the less or individual minimum impurity (as dust) of proportion, and length is less than the short flannel of 3mm, and what need to reclaim is short flannel wherein.
Thereby according to the present invention, first leftover bits and pieces makes short flannel and dust initial gross separation by the cleaning of rod descaling machine; The structure of rod descaling machine is depended in separation process, the rod of beating in rod descaling machine becomes screw type to arrange and be fixed on driving shaft, one wire side becomes 160 ° ~ 190 ° cornerites, be coated on driving shaft below, play rod and be adjusted at 2.5mm ~ 5mm with the gap of wire side, wire side is gone into battle and is shown the mesh of 1.2mm ~ 3mm, rely on excellent shredding and the helical feed effect of beating, make leftover bits and pieces and impurities removal wire side produce friction, in the auger of dust below falling into, be transported to one end and discharge from mesh, short flannel is played rod and is shifted one end onto and discharge from discharging opening.
Because mesh size can exert an influence to the rate of recovery of short flannel, if too large, obviously more short flannel can be taken as impurity discharge, less reserved more impurity in short flannel, but the separation is here preliminary separation, and therefore, mesh can be selected smaller value.
About tailing over, those skilled in the art should be noted that, the mesh of 3mm does not represent all crosses net the foreign material of all 3mm of being less than, but there is one, pass through constant, can be with reference to screening, but it should be noted that simultaneously due to here cross the not screening to weight of net, especially wherein short flannel proportion is very little, is easily subject to the disturbance of air-flow.Therefore, adopt the selection of beating rod and wire side gap, be conducive to the net of crossing of the impurity such as dust.
Further instruction, the mesh of 3mm, allows the foreign material of 2.1mm to pass through, and the material of 2.1 ~ 3mm is tailed over, and conventionally contains the coefficient of 0.7.Here lay particular emphasis on the less mesh of selection, when adopting 1.2 mesh, corresponding crosses net material particle diameter at 0.84mm, and unblocking dust can be crossed net substantially, and therefore, sieve aperture selects little, preferably selects the mesh of 1.2 ~ 2mm.And too short short flannel does not have value, minimum can not be less than 1.2mm, otherwise also can affect percentage of impurity, and subsequent treatment is more difficult.
Through the short flannel mixture obtaining after 10 cleanings of rod descaling machine, collect, the dust after separated is discharged from.Short flannel mixture after initial gross separation is carried by wind-force, meets the transporting that facilitates of light material.
The short flannel of discharging from rod descaling machine 10, also contain certain dust, need to collect machine through short flannel and reclaim and collect.
The short flannel that contains a certain amount of dust after treatment, the short flannel that namely rod descaling machine 10 is discharged is drawn in by short flannel descaling machine carries out secondary cleaning, further the dust in short flannel is discharged.Short flannel descaling machine increases circular arc type baffle plate by feeding suede roller bottom 8, make short flannel be unlikely to drop and can fully short flannel be fed in licker-in by the gap of hello suede roller, by linear velocity, in the hook effect of drawing of the licker-in of 40m/s High Rotation Speed, rely on centrifugal force that dust is kept off outside discharge machine by impurities removal plate resistance, the short flannel on licker-in is adsorbed on dust cage wire side and is stopped rear discharge by hairbrush by wind.
Finally complete the recovery of the rear short flannel of leftover bits and pieces cleaning: by wind-force, carry and carry out packing hollow-square receipts.
