Description
Technical field
The present invention relates to tobacco threshing redrying Processes and apparatus technical field, specifically is circulate the again method and apparatus of selection by winnowing of a kind of tobacco leaf after threshing machine is handled.
Background technology
At present, in China's tobacco threshing and redrying technical field, the afterbody of threshing machine group returns the stalk treatment system after beating leaf, and its working method is generally wind system and adopts open loop approach, and full negative pressure wind returns stalk selection by winnowing, conveying, dedusting method is full dedusting form, for guaranteeing back the conveying of when stalk offal, setting to return the stalk fan delivery generally all bigger because employing open loop, whole air quantity enter the full dedusting method of deduster, the deduster of corresponding configuration is also bigger, has increased equipment investment and energy consumption.
Summary of the invention
The objective of the invention is to solve the deficiency that above-mentioned prior art exists, provide a kind of material that is fit to more after air exercise leaf unit afterbody wind dispensing is handled to return the method and apparatus of stalk circulation selection by winnowing, threshing machine group afterbody wind can not only be divided the discharging of device to carry out more completely selection by winnowing and beat leaf, and adopt closed loop cycle wind form that material is carried out selection by winnowing and conveying, and control has only a small amount of air quantity to enter dust arrester, realize the part dedusting but not full dedusting, to reduce cleaner investment and energy consumption.
For achieving the above object, the present invention has adopted following technical scheme.
A kind of tobacco leaf returns stalk circulated air choosing method, be connected the circulated air pipeline and blower fan is set between the feeder above threshing machine group afterbody wind divides device and is arranged at threshing machine group feed arrangement, constitute the circulated air closed-loop system, the circulated air mode is adopted in the selection by winnowing of material and conveying, the running orbit of whole wind and conveyance conduit are closed loop, connect the dedusting breeches pipe that joins with dust arrester on the circulated air pipeline; Divide the discharging of device to split into two parts threshing machine group afterbody wind, with lighter part is that the feed arrangement that blade and the more stalk of band leaf send pipeline and feeder to be recycled to the threshing machine group by wind carries out once more selection by winnowing and beats leaf, and heavier part is pure offal and is with the less stalk of leaf to divide device to enter subsequent technique by wind and handles; Be back to the air inlet of blower fan after the wind that fan outlet is sent is carried by the circulated air pipeline again, the small part air quantity enters dust arrester and carries out the part dedusting.
Tobacco leaf returns stalk circulated air optional equipment, comprises that discharge end is provided with the threshing machine group of air classifier, and this equipment also is provided with blower fan, circulated air pipeline and feeder; Described circulated air pipeline is a closed-loop system, comprise the selection by winnowing pipeline that is connected between blower fan and the air classifier, be connected in air delivery pipe between air classifier and the feeder, be connected in the tube connector between feeder and the blower fan, be connected with the dedusting breeches pipe that is connected with dust arrester with the interface of selection by winnowing pipeline at blower fan.
Present device respectively is connected with a typhoon machine by symmetrically arranged tube connector respectively in the feeder both sides, also be connected with blower fan by symmetrically arranged selection by winnowing pipeline respectively in the air classifier both sides, connect an air delivery pipe from the top between feeder and air classifier, the blower fan in both sides all is connected with the dedusting breeches pipe that is connected with dust arrester with the interface of selection by winnowing pipeline.
Adopt the inventive method and equipment, the circulated air mode is adopted in the selection by winnowing of material and conveying, and the running orbit of whole wind and transfer pipeline are closed loop.After carrying by circulation line, the wind that fan outlet is sent is back to the air inlet of blower fan again, have only the small part air quantity to enter dust arrester, be the part dedusting, be different from the open loop mode that wind that existing fan outlet sends all is delivered to deduster, thereby realize effectively reducing the dedusting air quantity, reach and reduce deduster quantity, reduce the purpose of equipment investment and energy consumption.Simultaneously, also threshing machine group afterbody wind can be divided the discharging of device to carry out more completely selection by winnowing and beat leaf.
Device structure of the present invention is simple, the reliability height.Can directly on existing threshing machine group equipment, transform and realize.
Further set forth content of the present invention below in conjunction with Figure of description and embodiment.
