[0027] Optionally, for the stem-separation automatic recovery device with two-stage air separation and multi-channel sedimentation chambers according to the present invention, a secondary vibrating upward sieve is further provided at the output port of the rotary air lock to finally screen the cut tobacco after being screened again by the two-stage air separation mechanism;

[0028] A material conveying channel is provided at the cut tobacco outlet of the secondary vibrating upward sieve, and a conveyor is provided below the material conveying channel. The conveyor is located on one side of the platform and is used to convey the screened cut tobacco to the next process. The secondary vibrating upward sieve and the conveyor are both electrically connected to the electric control cabinet.

[0029] Optionally, for the stem-separation automatic recovery device with two-stage air separation and multi-channel sedimentation chambers according to the present invention, a ladder is further provided on one side of the platform. The ladder is used for the staff to climb onto the platform and detect the operation of each mechanism.

[0030] The beneficial effects of the present invention compared with the prior art are as follows:

[0031] 1. The ladder and the platform facilitate the operation and observation of the staff. The frame plays a fixing role. The feeding equipment can lift and convey the raw materials onto the primary vibrating upward sieve. After vibration classification, the raw materials are conveyed onto the two-stage air separation mechanism. Due to the action of the blower, the wind generated by the blower enables the raw materials to complete two-stage separation on the two-stage air separation mechanism. Those that are too large in volume or weight do not meet the requirements, and this part is recycled through the collection channel. Those that meet the requirements reach the sedimentation chamber through the conveying channel and then settle into the rotary air lock. The secondary vibrating upward sieve vibrates the raw materials at the second stage. After being screened by the secondary vibration, the raw materials reach the conveyor through the material conveying channel.

[0032] 2. The primary vibrating upward sieve is a three-layer vibrating sieve, which can classify and screen the raw materials according to the volume size. Then, the unqualified parts are removed through the subsequent two-stage air separation. Among them, the raw materials coming out of the outlet A of the vibrating sieve have the smallest volume, the raw materials coming out of the outlet B of the vibrating sieve are the second, and the raw materials coming out of the outlet C of the vibrating sieve have the largest volume.

[0033] 3. The primary air inlet A and the secondary air inlet of the primary air separation channel A play a role in ventilation, and can cooperate with the fan to generate an upward flowing wind force for air separation of the raw materials. The raw materials coming out from the outlet A of the vibrating screen enter the primary air separation channel through the feed inlet A. The raw materials with smaller volume or weight directly enter the conveying channel through the primary air separation channel A, and the remaining raw materials enter the secondary air separation channel A through the primary air separation channel A, and then undergo secondary air separation. The remaining raw materials with too large volume or weight are recycled through the collection channel. The working principles of the primary air separation channel B, the secondary air separation channel B, the primary air separation channel C, and the secondary air separation channel C are the same as above.

[0034] 4. Since the primary vibrating inclined screen and the two-stage air separation mechanism have divided the mixed cut tobacco materials into three categories according to their volume sizes, in order to avoid re-mixing of the materials during air separation, the present invention opens different channels in the conveying channel, so that the materials with different volume sizes enter different conveying channels respectively, and the air-separated cut tobacco is separately conveyed through the primary conveying channel A, the secondary conveying channel A, the primary conveying channel B, the secondary conveying channel B, the primary conveying channel C, and the secondary conveying channel C.

[0035] 5. The tobacco leaves coming from the primary conveying channel A and the secondary conveying channel A reach the swirling area at the top of the collection bin A through the sedimentation channel A, and then fall into the rotary valve through the collection bin. The size of the connection between the fan bin A and the collection bin A is smaller than the size of the fan bin A. The narrower connection can prevent the tobacco leaves from entering the fan bin A. The fan bin A, in cooperation with the primary air inlet A and the secondary air inlet, can ensure the wind speed and wind force of the entire channel. The working principles of the sedimentation channel B, the fan bin B, the collection bin B, the sedimentation channel C, the fan bin C, and the collection bin C are the same as above.

[0054] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that: unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0056] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification.

[0057] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as limitations. Thus, other examples of the exemplary embodiments may have different values.

[0058] It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0059] According to Figures 1 to 12 as shown, the present invention provides a stem separation automatic recovery device with two-stage air separation and a multi-channel sedimentation chamber, including a platform 2, an electric control cabinet 15, a lifting and feeding device 4, a first-stage vibrating upward sieve 5, a two-stage air separation mechanism 6, a conveying channel 7, and a sedimentation chamber 9.

[0060] A frame 1 for support is provided below the platform 2, and the lifting and feeding device 4 is arranged on one side of the platform 2, which is used for lifting and conveying the mixed materials; the first-stage vibrating upward sieve 5 is connected to the material outlet of the lifting and feeding device 4, which is used for preliminarily vibrating and screening the stem silk in the mixed materials.

[0061] The two-stage air separation mechanism 6 is connected to the material outlet of the first-stage vibrating upward sieve 5, which is used for secondarily air separating the preliminarily screened stem silk to re-screen the tobacco stems and tobacco leaves; the conveying channel 7 connects the sedimentation chamber 9 with the two-stage air separation mechanism 6, and a blower 10 is provided on one side of the sedimentation chamber 9. An air inlet cooperating with the blower 10 is provided at the bottom of the two-stage air separation mechanism 6, and the air inlet is also used for discharging the tobacco stems. The conveying channel 7 is used for adjusting the air volume in the two-stage air separation mechanism 6.

[0062] A rotary air lock 11 is further provided at the bottom on the other side of the sedimentation chamber 9, and the rotary air lock 11 is used for conveying the tobacco leaves sedimented in the sedimentation chamber 9 out; the electric control cabinet 15 is used for controlling the start and stop of the lifting and feeding device 4, the first-stage vibrating upward sieve 5, the conveying channel 7, and the blower 10.

[0063] In this embodiment, the platform 2 is used to support the overall structure of the present invention. The feeding device 4 can convey raw materials onto the first-stage vibrating upward sieve 5. After vibration classification, the raw materials are then conveyed onto the two-stage air separation mechanism 6. Due to the action of the fan 10, the wind generated by the fan 10 enables the raw materials to complete two-stage separation on the two-stage air separation mechanism 6. Those that are too large in volume or weight do not meet the requirements, and this part is discharged and recycled through the air inlet. Those that meet the requirements then reach the sedimentation chamber 9 through the conveying channel 7 and are further sedimented into the air lock 11. The air lock 11 is used to convey the cut tobacco sedimented in the sedimentation chamber 9 out.

[0064] Further, the first-stage vibrating upward sieve 5 is a three-layer vibrating sieve. The first-stage vibrating upward sieve 5 is provided with a vibrating sieve outlet A16, a vibrating sieve outlet B17, and a vibrating sieve outlet C18, which are respectively connected to the low, middle, and high layers of the first-stage vibrating upward sieve 5. The vibrating sieve outlet A16, the vibrating sieve outlet B17, and the vibrating sieve outlet C18 are respectively connected to the two-stage air separation mechanism 6. The first-stage vibrating upward sieve 5 being a three-layer vibrating sieve can classify and screen the raw materials according to their volume size, and then eliminate the parts that do not meet the requirements through the subsequent two-stage air separation. Among them, the raw materials coming out of the vibrating sieve outlet A16 have the smallest volume, the raw materials coming out of the vibrating sieve outlet B17 are the second, and the raw materials coming out of the vibrating sieve outlet C18 have the largest volume.

[0065] Still further, the two-stage air separation mechanism 6 includes a first-stage air separation channel A19, a second-stage air separation channel A21, a first-stage air separation channel B23, a second-stage air separation channel B25, a first-stage air separation channel C27, and a second-stage air separation channel C29 that are arranged in a 2*3 arrangement and are closely distributed. And the first-stage air separation channel A19, the first-stage air separation channel B23, and the first-stage air separation channel C27 are located on the side facing the first-stage vibrating upward sieve 5.

[0066] The first-stage air separation channel A19 is provided with a feed port A20 connected to the vibrating sieve outlet A16, the first-stage air separation channel B23 is provided with a feed port B24 connected to the vibrating sieve outlet B17, and the first-stage air separation channel C27 is provided with a feed port C28 connected to the vibrating sieve outlet C18.

[0067] The first-stage air separation channel A19, the first-stage air separation channel B23, and the first-stage air separation channel C27 are used to perform air separation on the cut tobacco from the three outlets of the first-stage vibrating upward sieve 5; the second-stage air separation channel A21, the second-stage air separation channel B25, and the second-stage air separation channel C29 are used to perform air separation on the cut tobacco that falls to the air inlet.

[0068] In this embodiment, since the primary vibrating upward sieve 5 has already classified the mixed cut tobacco materials into three categories according to their volume sizes, in order to prevent the materials from being mixed again during the air separation process, the present invention provides different feed inlets on the two-stage air separation mechanism 6, so that materials of different volume sizes enter different air separation channels respectively, ensuring the air separation effect of the two-stage air separation mechanism 6 on the cut tobacco. Moreover, the cut tobacco after air separation has been preliminarily screened by the primary vibrating upward sieve 5 in advance, which facilitates the subsequent conveying channel 7 to adjust the air volume according to the cut tobacco of different volume sizes, improving the air separation effect of the present invention.

[0069] Furthermore, the air inlets include a primary air inlet A22, a primary air inlet B26, a primary air inlet C30, and a secondary air inlet 31. The primary air inlet A22 is arranged below the feed inlet A20, and its interior is connected to the primary air separation channel A19 and the secondary air separation channel A21; the primary air inlet B26 is arranged below the feed inlet B24, and its interior is connected to the primary air separation channel B23 and the secondary air separation channel B25; the primary air inlet C30 is arranged below the feed inlet C28, and its interior is connected to the primary air separation channel C27 and the secondary air separation channel C29.

[0070] The secondary air inlet 31 is arranged below the secondary air separation channel A21, the secondary air separation channel B25, and the secondary air separation channel C29, and it is also connected to a collection channel 8, which is used to discharge the tobacco stems.

[0071] In this embodiment, the primary air inlet A22 of the primary air separation channel A19 and the secondary air inlet 31 play a role in ventilation, and can cooperate with the fan 10 to generate an upward flowing wind force for air separating the raw materials. The raw materials coming out from the vibrating sieve outlet A16 enter the primary air separation channel through the feed inlet A20. The materials with smaller volume or weight directly enter the conveying channel 7 through the primary air separation channel A19, and the remaining raw materials enter the secondary air separation channel A21 through the primary air separation channel A19, and then undergo secondary air separation. The remaining materials with too large volume or weight are recycled through the collection channel 8. The working principles of the primary air separation channel B23, the secondary air separation channel B25, the primary air separation channel C27, and the secondary air separation channel C29 are the same as above.

[0072] Furthermore, the conveying channel 7 includes a primary conveying channel A34, a secondary conveying channel A38, a primary conveying channel B42, a secondary conveying channel B46, a primary conveying channel C50, and a secondary conveying channel C54 arranged in a 2*3 array and distributed in a fitting manner, which are used to adjust the air volume sizes of different air separation channels in the two-stage air separation mechanism 6 respectively.

[0073] The primary conveying channel A34 is connected to the upper end of the primary air separation channel A19, the primary conveying channel B42 is connected to the upper end of the primary air separation channel B23, and the primary conveying channel C50 is connected to the upper end of the primary air separation channel C27.

[0074] The upper end of the secondary conveying channel A38 is connected to the upper end of the secondary air separation channel A21. The upper end of the secondary conveying channel B46 is connected to the upper end of the secondary air separation channel B25. The upper end of the secondary conveying channel C54 is connected to the upper end of the secondary air separation channel C29.

[0075] In this embodiment, since the primary vibrating inclined screen 5 and the two-stage air separation mechanism 6 have already classified the mixed cut tobacco materials into three categories according to their volume sizes, in order to avoid the materials being mixed again during air separation, the present invention opens different channels in the conveying channel 7, so that materials of different volume sizes enter different conveying channels 7 respectively, and the cut tobacco after air separation is separately conveyed through the primary conveying channel A34, the secondary conveying channel A38, the primary conveying channel B42, the secondary conveying channel B46, the primary conveying channel C50, and the secondary conveying channel C54.

[0076] Furthermore, transparent glass observation windows 58 are provided on the respective independent side walls of the primary conveying channel A34, the primary conveying channel B42, the primary conveying channel C50, the secondary conveying channel A38, the secondary conveying channel B46, and the primary conveying channel C50. Through the glass observation windows 58, the air separation situation in the conveying channel 7 can be viewed in real time, so as to facilitate the operator to adjust the air volume in different conveying channels 7.

[0077] Furthermore, the sedimentation chamber 9 includes a sedimentation channel A59, a sedimentation channel B62, and a sedimentation channel C65 for separately sedimenting cut tobacco of different volumes.

[0078] The sedimentation channel A59 communicates with the upper ends of the primary conveying channel A34 and the secondary conveying channel A38. The sedimentation channel B62 communicates with the upper ends of the primary conveying channel B42 and the secondary conveying channel B46. The sedimentation channel C65 communicates with the upper ends of the primary conveying channel C50 and the secondary conveying channel C54.

[0079] In this embodiment, it is mentioned above that the primary vibrating inclined screen 5 has classified the mixed cut tobacco materials into three categories according to their volume sizes. In order to avoid the materials being mixed again after air separation, the present invention opens different sedimentation channels in the sedimentation chamber 9. Since both the primary air separation channel A19 and the secondary air separation channel A21 are connected to the feed port A20, the sedimentation channel A59 can be directly connected to the primary conveying channel A34 and the secondary conveying channel A38. Correspondingly, the sedimentation channel B62 should also be connected to the upper ends of the primary conveying channel B42 and the secondary conveying channel B46, and the sedimentation channel C65 should be connected to the upper ends of the primary conveying channel C50 and the secondary conveying channel C54, so as to achieve the purpose of sedimenting cut tobacco of different volumes.

[0080] Furthermore, there is a collection bin at the bottom of the other side of the sedimentation chamber 9 away from the conveying channel 7. The air lock 11 is arranged at the bottom of the collection bin. The collection bin includes collection bin A60, collection bin B63, and collection bin C66.

[0081] The outlet of the sedimentation channel A59 and the collection bin A60 form an arc-shaped swirling area. Above the collection bin A60, there is also a blower bin A61 connected to the collection bin A60; the outlet of the sedimentation channel B62 and the collection bin B63 form an arc-shaped swirling area. Above the collection bin B63, there is also a blower bin B64 connected to the collection bin A60.

[0082] The outlet of the sedimentation channel C65 and the collection bin C66 form an arc-shaped swirling area. Above the collection bin C66, there is also a blower bin C67 connected to the collection bin A60; the blower bin A61, the blower bin B64, and the blower bin C67 are all connected to the blower 10 so that the blower 10 is connected to the air inlet.

[0083] In this embodiment, the tobacco leaves from the primary conveying channel A34 and the secondary conveying channel A38 reach the swirling area at the top of the collection bin A60 through the sedimentation channel A59, and then fall into the air lock 11 through the collection bin. The size of the connection between the blower bin A61 and the collection bin A60 is smaller than the size of the blower bin A61. The narrower connection can prevent tobacco leaves from entering the blower bin A61. The blower bin A61, in cooperation with the primary air inlet A22 and the secondary air inlet 31, can ensure the air speed and wind force of the entire channel. The working principles of the sedimentation channel B62, the blower bin B64, the collection bin B63, the sedimentation channel C65, the blower bin C67, and the collection bin C66 are the same as above.

[0084] Furthermore, a secondary vibrating upward sieve 12 is also arranged at the output port of the air lock 11 to perform a final screening on the cut tobacco that has been screened again by the two-stage air separation mechanism 6.

[0085] At the cut tobacco outlet of the secondary vibrating upward sieve 12, there is a material conveying channel 13. Below the material conveying channel 13, there is a conveyor 14. The conveyor 14 is located on one side of the platform 2 and is used to convey the screened cut tobacco to the next process. The secondary vibrating upward sieve 12 and the conveyor 14 are both electrically connected to the electric control cabinet 15. The secondary vibrating upward sieve 12 performs secondary vibration on the air-separated cut tobacco, and the quality of the cut tobacco after the secondary vibration screening is effectively improved.
