Abstract
The invention discloses a method for flexibly transmitting tobacco via wind, wherein the material is fed into vertical wind tube via a transmitter, to remove foreign material via the suspension speed difference, to move upwards in vertical wind tube, and enter into the large bended end whose section is larger than vertical wind tube, to be decelerated and steered to enter into a horizontal transmission tube to be fed into preset point. The invention has the advantages in increased section at turn, reduced airflow speeds, steered forward directions and reduced impact on tube wall or the like.
Description
Technical field
The present invention relates to the technical method that a kind of tobacco is carried, specifically relate to the method that a kind of tobacco flexible wind is carried.
Background technology
In the tobacco production process, a large amount of methods of using strength to carry are grown the distance conveying to tobacco or are promoted, in the predetermined area, utilize the gas material separating device with tobacco and burbling, under many occasions, strength is carried has clear superiority, simple, floor area is little, is irreplaceable.But, because it is often lower to carry out the material moisture that strength carries, through being everlasting about 12.5%, and often be accompanied by bigger mechanical force in the process of pneumatic transmission, so strength carries to exist and makes broken big defective, form huge waste.
Make broken in the easy generation of following key link tobacco in the air-transport system that uses at present: charging, pipeline turning, separation place of gas material; And in order to ensure the delivery system reliable operation, air-flow velocity is far above the needed speed of normal drive in air-transport system, and high-speed motion has also aggravated material and made broken degree.
For easy construction, use the delivery duct of circular section at present in the air-transport system that uses mostly, and system's delivery duct everywhere is prismatic.
Therefore, the making of back stem of expanding in the minimizing process of pneumatic transmission is broken, to reduce the production of cigarettes cost, improves the product design of cigarette, is tobacco business technical matters suddenly to be solved.
Summary of the invention
The objective of the invention is easily to make tobacco make broken deficiency at existing on turn in the existing air-transport system, and the method that a kind of tobacco that proposes carries flexible wind to carry.
Technical scheme of the present invention is: the method that a kind of tobacco flexible wind is carried, after tobacco is sent in the vertical airduct by load transfer device, at first utilize the difference of floating velocity to carry out the removal of impurities purification, tobacco after removal of impurities is purified is at the vertical airduct upward movement in the drive lower edge of air-flow, enter the vertical big heavy in section elbow of airduct in cross section then, tobacco finishes that deceleration, conversion working direction are laggard goes into horizontal delivery pipe and be transported to the predetermined area in the elbow of heavy in section.
The device that a kind of tobacco flexible wind is carried, comprise vertical airduct, horizontal conveying pipe is connected the bend pipe of vertical airduct and horizontal conveying pipe, described bend pipe is the elbow tube with varying section of sectional area greater than the sectional area of vertical airduct and horizontal conveying pipe, is bottom-up magnify gradually horn-like.
When bend pipe was rectangular tube with vertical airduct, the top sectional area S1 of bend pipe was 0.8-2 a times of the long-pending S2 of vertically-supplying air tube section, and the height h of bend pipe equals 3-5 times of vertical airduct width.
When bend pipe was cylindrical tube with vertical airduct, the top sectional area S1 of bend pipe was 0.8-2 a times of the long-pending S2 of vertically-supplying air tube section, and the height h of bend pipe equals 3-5 times of vertical dust diameter.
Because the on turn sectional area progressively increases, air-flow velocity just progressively reduces, and the conversion working direction, thereby has reduced the impulsive force of on turn tobacco to tube wall, makes brokenly also to significantly reduce.
Major advantage of the present invention is:
1, adopts flexible pneumatic conveying method of tobacco provided by the invention and device, tobacco is carried out making when strength is carried broken little, can significantly reduce the waste in the production process degree, reduce production costs.
2, the device loss of pressure is low, energy consumption is little, and productive costs is low.
3, apparatus structure is simple, fault rate is low, long service life.
Description of drawings
Accompanying drawing is the scheme drawing of one embodiment of the present of invention;
Among the figure: 1, vertical airduct, 1-1, inlet point, 2, elbow tube with varying section, 3, horizontal conveying pipe, 4, the gas material separates casing, 5, the discharging gas lock, 6, dust removing tube, 7, material conveyor.
The specific embodiment
Below with reference to drawings and Examples the present invention is described in further detail.
As shown in drawings, the chief component of flexible selection by winnowing blast system has vertical air separation tube 1, elbow tube with varying section 2, horizontal conveying pipe 3, gas material to separate casing 4, discharging gas lock 5, dust removing tube 6 etc.Vertical in the present embodiment airduct 1, elbow tube with varying section 2, horizontal conveying pipe 3 is rectangular tube.Elbow tube with varying section 2 one ends link to each other with vertical airduct 1, and the other end links to each other with horizontal conveying pipe 3, and with 1 one-tenth 90 ° of vertical air separation tubes.Elbow tube with varying section 2 bottom-up chaps gradually, its top sectional area S1 is 1.9 times of vertical airduct 1 sectional area S2, the height h of bend pipe 2 equals 3 times of vertical airduct 1 width.The experiment proved that, if the top sectional area S1 of bend pipe 2 then is prone to the buildup phenomenon greater than 2 times of vertical airduct 1 sectional area S2; If the top sectional area S1 of bend pipe 2 is less than 0.8 times of vertical airduct 1 sectional area S2, then tobacco is made broken still more.
The principle of work of flexible selection by winnowing blast system provided by the invention is such: after material is sent in the vertical airduct 1 by conveyer 7 from inlet point 1-1, because of in vertical air separation tube 1, remaining air-flow vertically upward, the moving speed of this air-flow is slightly larger than the floating velocity of convey materials, at first utilize the difference of floating velocity to carry out the removal of impurities purification, the foreign material that mass density is big can not be taken away by air-flow, fall from the bottom of vertical airduct 1; Material is vertical airduct 1 upward movement in the drive lower edge of air-flow then, enter elbow tube with varying section 2 after being promoted to certain altitude, after air-flow enters variable section elbow 2 from vertical air separation tube 1, because sectional area progressively increases, air-flow velocity progressively reduces, and the conversion working direction, equally, material enters variable section elbow 2 speed also progressively to be reduced, and the impulsive force to tube wall when the conversion working direction reduces greatly, makes broken also reduction greatly.Material has finished that deceleration, conversion working direction are laggard goes into horizontal delivery pipe 3 in elbow tube with varying section 2, be transported to the predetermined area, below in the predetermined area is that the gas material separates casing 4, finishing the gas material in the gas material separates casing 4 separates, material is discharged from the discharging gas lock 5 that the gas material separates casing 4 belows, and air-flow discharges after entering dust removing tube 6 dust removal process.
