The utility model provides a winnowing machine 100, include:
a feed duct 110 for inputting cut tobacco; that is, the feeding duct 110 may convey the cut tobacco along its extending direction, for example, the feeding duct 110 is a belt conveyor.
The discharging conveying pipe 120 is arranged opposite to the feeding conveying pipe 110 at intervals and used for outputting tobacco shreds; that is, the output conveying pipe 120 can convey the cut tobacco along the extending direction thereof, for example, the output conveying pipe 120 is a belt conveyer.
An air inlet pipe 130 arranged between the feeding conveying pipe 110 and the discharging conveying pipe 120, wherein the generated air is used for screening the cut tobacco of the feeding conveying pipe 110, the cut tobacco with the qualified quality is blown to the discharging conveying pipe 120, and the cut tobacco with the unqualified quality falls down from the gap between the feeding conveying pipe 110 and the discharging conveying pipe 120 and is removed; that is, air inlet duct 130 is provided with an air jet head facing the gap between feed duct 110 and discharge duct 120 so that the cut tobacco moves parabolically by the push of the air and falls onto discharge duct 120.
The air disposed in the air inlet pipe 130 is warm air.
Specifically, when the winnowing machine 100 is in operation, the cut tobacco is conveyed along the feeding conveying pipe 110, the cut tobacco is screened by the warm air generated by the air inlet pipe 130, wherein the cut tobacco (standard quality) with satisfactory quality is blown to the discharging conveying pipe 120, and the cut tobacco (larger quality) with unsatisfactory quality falls down from the gap between the feeding conveying pipe 110 and the discharging conveying pipe 120 and is removed; because the flavor warm air generated by the air inlet pipe 130 can avoid a large temperature difference with the cut tobacco, the 'breaking' rate of the cut tobacco is greatly reduced, the screening effect is ensured, and the device has a simple structure and high screening efficiency.
In an example of the present invention, the present invention further includes: the air separation box 140 is provided with a plurality of air separation boxes,
a chamber 141 is arranged inside, wherein the feeding conveying pipe 110 and the discharging conveying pipe 120 are respectively arranged at two opposite sides of the air separation box 140, so that a gap between the feeding conveying pipe 110 and the discharging conveying pipe 120 is formed in the chamber 141;
that is to say, the tobacco shred screening of the winnowing machine 100 is completed in the winnowing box 140, so that the tobacco shred is always in the chamber 141 in the screening process, thereby avoiding the influence on the screening effect and efficiency due to the scattering of the tobacco shred everywhere caused by the wind of the air inlet, and ensuring the screening environment.
In an example of the present invention, the present invention further includes: an air outlet pipe 150 is arranged on the air outlet pipe,
which is disposed on the winnowing box 140 and communicated with the chamber 141;
through setting up out tuber pipe 150, can be with the stable discharge of the wind that is located winnowing box 140, avoid the air current to appear disorderly and influence the screening effect of air-supply line 130.
Preferably, the air outlet pipe 150 is disposed at the upper end of the air selecting box and is located at the side opposite to the air inlet pipe 130; the air outlet pipe 150 is arranged to facilitate the air to be discharged from the chamber 141 because the air of the air inlet pipe 130 is blown from the bottom to the top and toward the discharging duct 120.
In an example of the present invention, a filter screen is disposed on the air outlet pipe 150 to limit the cut tobacco in the chamber 141;
through setting up the filter screen can prevent that the pipe tobacco from discharging from the port that goes out tuber pipe 150, avoid the pipe tobacco to scatter and cause the influence to workshop environment, also can avoid the waste of pipe tobacco simultaneously.
In one example of the present invention, the height of the feeding duct 110 in the height direction H is higher than the height of the discharging duct 120 in the height direction H;
because the air inlet pipe 130 blows obliquely, a pushing force is given to the cut tobacco output by the feeding conveying pipe 110, so that the cut tobacco completes parabolic movement, and the feeding conveying pipe 110 and the discharging conveying pipe 120 are provided with a height difference, so that the cut tobacco is received by the discharging conveying pipe 120 under the action of wind power.
It is of course also possible, as shown in fig. 1, that the feeding duct 110 and the discharging duct 120 are at the same height, in short, the height difference between them depends on the wind pressure of the air inlet duct 130 and the direction of the air jet head thereof, as long as the tobacco shreds with the consistent quality can fall to the discharging duct 120 under the action of the gas, and the tobacco shreds with the inconsistent quality can fall to the gap.
In an example of the present invention, the present invention further includes: the conveyor belt(s) 160 are,
fitted at the lower ends of said infeed and outfeed ducts 110, 120 and such that the spacing between said infeed and outfeed ducts 110, 120 is at least partially projectable onto the belt face of the conveyor belt 160;
wherein, the direction of delivery of conveyer belt 160 is by ejection of compact conveyer pipe 120 towards feeding conveyer pipe 110 direction, can make the pipe tobacco of being rejected can carry to appointed processing place under the transport of conveyer belt 160 through setting up conveyer belt 160, conveniently to the recovery of rejecting the pipe tobacco.
In one example of the present invention, the space between the feed duct 110 and the discharge duct 120 can be projected completely on the belt surface of the conveyor belt 160;
therefore, the rejected cut tobacco can be completely received by the conveying belt 160, and the cut tobacco is prevented from splashing, so that the recovery effect is better.
In an example of the present invention, a warm air device 170 is disposed on the air inlet pipe 130 to heat the air in the air inlet pipe 130 to form the warm air;
the air in the air inlet pipe 130 can be effectively heated by the air heating device 170, so that the difference between the temperature of the air in the air inlet pipe 130 and the temperature of the cut tobacco on the feeding conveying pipe 110 is reduced, and the probability of the broken cut tobacco clusters is greatly reduced. Preferably, the heater unit 170 is a steam heat exchanger, which has a small size, high heat exchange efficiency and low noise.
In an example of the present invention, the temperature of the warm air is close to or equal to the temperature of the cut tobacco input by the feeding duct 110, so that the "breaking up" rate of the cut tobacco can be reduced to the maximum extent, and the screening effect is optimal.
The exemplary embodiment of the air classifier 100 proposed by the present invention has been described in detail with reference to the preferred embodiments, however, it will be understood by those skilled in the art that various modifications and changes can be made to the above specific embodiments without departing from the concept of the present invention, and various combinations of the various technical features and structures proposed by the present invention can be made without departing from the scope of the present invention, which is defined by the appended claims.
