Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, and in particular to a vertical wind separator for tobacco leaves. Background Technology

[0002] In the tobacco (leaf) processing, after drying (baking), the tobacco leaves are usually cooled by an air classifier. This air classifier rapidly reduces the temperature of the leaves from around 60°C to 35°C, while simultaneously separating out the stems and stalks. Air classifiers typically employ two types of equipment: VAS (Flow Cooling Air Classifier) ​​and in-situ FS (In-situ Air Classifier). Each type has its own advantages and disadvantages.

[0003] Since the stem content in leaf shreds is approximately 1.5% to 2.0% (based on the total leaf shreds content, the same below), the VAS air separation equipment is effective at removing stems, generally able to remove 1% of stems, but it cannot remove clumps or wet clumps of leaf shreds. The FS air separation equipment is effective at removing clumps and wet clumps of leaf shreds, but can only remove 0.35% of stems, placing greater pressure on subsequent cigarette rolling processes.

[0004] In addition to air separation devices for other filamentous structures such as stems, there are also chamber air separation devices, such as internal feeding air separation devices. Their air separation efficiency is generally higher than other air separation devices. However, if applied to leaf filaments, it will cause leaf filament breakage, that is, the leaf filament foam content will increase, and it cannot effectively deal with the clumped leaf filaments and wet leaf filaments, resulting in a great waste of leaf filaments.

[0005] Therefore, there is an urgent need for a vertical blade air separator to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a vertical air separator for leaf filaments, which can improve the air separation efficiency of stems and stalks in leaf filaments, solve the problem of leaf filament clumping and wet clumping, and improve the utilization rate of leaf filaments.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] Vertical air separator with blades, including:

[0009] The air separation chamber has an air extraction device connected to its top to allow airflow from bottom to top within it. The air separation chamber includes a first air separation chamber and a second air separation chamber. The second air separation chamber is connected to the bottom of the first air separation chamber. The air velocity in the first air separation chamber is lower than that in the second air separation chamber. The air separation chamber also has a feed inlet for supplying blades. The feeding direction of the blades is opposite to the airflow direction.

[0010] The blade filament shuffling component is disposed at the bottom of the second air separation chamber and is used to block and break up the clumps of blade filaments.

[0011] Optionally, the air separation cavity further includes a waist-shaped connecting cavity, the two ends of which are respectively connected to the first air separation cavity and the second air separation cavity, and the maximum diameter ratio of the first air separation cavity, the waist-shaped connecting cavity and the second air separation cavity is 1:(0.5-0.65):(0.7-0.85).

[0012] Optionally, the height ratio of the first air separation chamber to the air separation chamber body is 1:(2.5-4.0).

[0013] Optionally, the aforementioned filament shuffling assembly includes a drive member, a first rotating filament-breaking knife, and a second rotating filament-breaking knife. The first rotating filament-breaking knife is disposed on top of the second rotating filament-breaking knife, and the blades of the first rotating filament-breaking knife and the second rotating filament-breaking knife are arranged facing each other. The drive end of the drive member is connected to the first rotating filament-breaking knife and / or the second rotating filament-breaking knife to drive the first rotating filament-breaking knife and / or the second rotating filament-breaking knife to rotate.

[0014] Optionally, the above-mentioned leaf filament shuffling component also includes a wire-blocking mesh, which is spaced at the bottom of the second rotating wire-breaking knife. The wire-blocking mesh has multiple through holes with a cross-sectional area of ​​S. The minimum cross-sectional area of ​​the leaf filament is S1, and the maximum cross-sectional area of ​​the stem is S2, where S2≤S≤S1.

[0015] Optionally, it also includes a feed pipe, which is disposed at the feed inlet of the air separation chamber. The feed pipe includes a feed end and an extension end. The feed end can be connected to an external feeding device, and the extension end is disposed in the middle of the first air separation chamber to supply blades to the air separation chamber.

[0016] Optionally, the cross-sectional area of ​​the feed tube gradually decreases from the feed end to the extension end.

[0017] Optionally, the cross-sectional shape of the feed end of the feed pipe is elliptical.

[0018] Optionally, it also includes an airflow diversion shuttle, which is disposed at the bottom of the second air selection chamber, and the blade shuffling assembly is sleeved on the outer periphery of the airflow diversion shuttle. The airflow diversion shuttle is used to divert the airflow in the second air selection chamber.

[0019] Optionally, it also includes a blade splitter shuttle, which is disposed in the first air separation chamber and located at the bottom of the feed inlet of the air separation chamber.

[0020] The beneficial effects of this utility model are:

[0021] This invention provides a vertical tobacco leaf air separator. By setting up a first air separation chamber, a second air separation chamber, and a tobacco leaf shredding component, and employing a feeding-type material delivery, it avoids the problem of tobacco leaf breakage caused by throwing materials. The tobacco leaves enter the first air separation chamber for air separation. During air separation, the separated tobacco leaves are discharged to the next process, while tobacco leaves with many stems and clumps fall into the second air separation chamber for air separation. The separated tobacco leaves return to the first air separation chamber for further air separation, and the separated stems fall and are discharged. Clumps of tobacco leaves fall to the tobacco leaf shredding component for dispersal, allowing the dispersed tobacco leaves to undergo air separation in the second air separation chamber. This achieves the processing and effective utilization of clumps of tobacco leaves, improving tobacco leaf utilization. Furthermore, the different air separation methods in the two air separation chambers improve air separation efficiency, accuracy, and tobacco leaf purity. Moreover, this vertical tobacco leaf air separator has a simple structure, is easy to operate, and is inexpensive, significantly reducing equipment costs. Attached Figure Description

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] The following reference Figures 1 to 5 This invention introduces the blade-type vertical air separator provided by this utility model.

[0039] Please refer to Figure 1 and Figure 2This embodiment provides a vertical air separator for leaf filaments, which includes an air separation chamber 10 and a leaf filament shuffling assembly 20. The top of the air separation chamber 10 is connected to an air extraction device so that airflow flows from the bottom to the top within the air separation chamber 10. The air separation chamber 10 includes a first air separation chamber 11 and a second air separation chamber 12. The second air separation chamber 12 is connected to the bottom of the first air separation chamber 11. The wind speed in the first air separation chamber 11 is lower than the wind speed in the second air separation chamber 12. The air separation chamber 10 is also provided with a feed inlet for supplying leaf filaments. The feeding direction of the leaf filaments is opposite to the flow direction of the airflow. The leaf filament shuffling assembly 20 is disposed at the bottom of the second air separation chamber 12 and is used to block and break up clumps of leaf filaments.

[0040] The vertical tobacco leaf air separator in this embodiment, by setting up a first air separation chamber 11, a second air separation chamber 12, and a tobacco leaf shredding component 20, adopts a feeding-type material delivery to avoid the problem of tobacco leaf breakage caused by throwing material. The tobacco leaves enter the first air separation chamber 11 for air separation. During the tobacco leaf air separation, the air-separated tobacco leaves are discharged to the next process, while tobacco leaves with a large number of stems and clumps fall into the second air separation chamber 12 for air separation. The air-separated tobacco leaves return to the first air separation chamber 11 for air separation again. The stems and clumps separated by air separation fall and are discharged. The clumps of tobacco leaves fall to the tobacco leaf shredding component 20 for breaking up, so that the broken tobacco leaves are air-separated again in the second air separation chamber 12. This realizes the processing and effective utilization of clumps of tobacco leaves, improves the utilization rate of tobacco leaves, and improves the air separation efficiency, air separation accuracy, and tobacco leaf purity by using different air separation methods in the two air separation chambers. Furthermore, this blade vertical air separator has a simple structure, is easy to operate, and is inexpensive, which can significantly reduce equipment costs.

[0041] Furthermore, tests show that when using the vertical air separator for leaf separation in this embodiment, the leaf separation efficiency is as high as 99.5%, and the stem removal rate can reach more than 1.45%.

[0042] Optionally, the wind speed in the second air separation chamber 12 is 1.6 times the wind speed in the first air separation chamber 11. For example, the wind speed in the first air separation chamber 11 is approximately 4 m / s, and the wind speed in the second air separation chamber 12 is approximately 6.4 m / s. This is because the suspension velocity of pure leaf filaments ranges from 2.15 m / s to 4.5 m / s, the suspension velocity of leaf filaments containing stems ranges from 3.5 m / s to 6.75 m / s, and the suspension velocity of stems ranges from 6.75 m / s to 10.8 m / s. This ensures that the wind speed selection in the air separation chambers guarantees that pure leaf filaments are air-separated and rise to the surface in the first air separation chamber 11, while leaf filaments containing stems fall into the second air separation chamber 12 for secondary air separation, separating the pure leaf filaments from the stems. The pure leaf filaments then enter the first air separation chamber 11, while the stems fall and are discharged.

[0043] Furthermore, the air separation cavity 10 also includes a waist-shaped connecting cavity 13, the two ends of which are connected to the first air separation cavity 11 and the second air separation cavity 12 respectively, thereby making the air separation cavity 10 form a gourd-shaped structure. This shape is more conducive to the formation of the first air separation cavity 11 and the second air separation cavity 12, and optimizes the internal airflow path and air separation area.

[0044] Optionally, the maximum diameter ratio of the first air separation chamber 11, the waist-shaped connecting chamber 13, and the second air separation chamber 12 is 1:(0.5-0.65):(0.7-0.85). This is a suitable maximum diameter range for the air separation chamber 10, ensuring that the wind speed and air separation area in the first air separation chamber 11 and the second air separation chamber 12 meet the requirements. This allows air separation to be carried out in the air separation chamber 10 within this range, which is beneficial to improving the efficiency of leaf filament air separation, air separation accuracy, and stem removal effect.

[0045] For example, the maximum diameter ratio of the first air separation cavity 11, the waist-shaped connecting cavity 13, and the second air separation cavity 12 is 1:0.5:0.7, 1:0.5:0.75, 1:0.5:0.8, 1:0.5:0.85, 1:0.55:0.7, 1:0.55:0.75, 1:0.55:0.8, 1:0.55:0.85, 1:0.6:0.7, 1:0.6:0.75, 1:0.6:0.8, 1:0.6:0.85, 1:0.65:0.7, 1:0.65:0.75, 1:0.65:0.8, or 1:0.65:0.85.

[0046] Optionally, the height ratio of the first air separation chamber 11 to the air separation chamber 10 is 1:(2.5-4.0). By changing the height, the air separation area in the first air separation chamber 11 can be changed. This is a suitable height range for the air separation chamber 10, so that the wind speed and air separation area in the first air separation chamber 11 and the second air separation chamber 12 both meet the requirements. This allows air separation to be carried out in the air separation chamber 10 within this range, which is beneficial to improving the efficiency, accuracy and purity of the leaf filament air separation.

[0047] For example, the height ratio of the first air separation chamber 11 to the air separation chamber 10 is 1:2.5, 1:3, 1:3.5 or 1:4.

[0048] It is understandable that the dimensions of each position of the air separation chamber 10 can be adapted to the airflow rate, and no specific limitation is made here.

[0049] Furthermore, the air separation chamber 10 also includes a discharge port 101 and a waste port 102. The discharge port 101 and the waste port 102 are respectively located at the top and bottom of the air separation chamber 10. The discharge port 101 is used for the flow of pure leaf filaments separated by air separation, and the waste port 102 is used for the flow of waste materials such as stems and twigs. The discharge port 101 is also connected to an air extraction device, while the waste port 102 serves as an air inlet so that an airflow from the bottom to the top flows through the air separation chamber 10.

[0050] Optionally, a dust collection hopper is also provided at the waste outlet 102 to collect waste such as guide sticks, so as to avoid splashing and pollution when the waste is discharged.

[0051] Please refer to Figures 3 to 5 In this embodiment, the leaf filament shuffling assembly 20 includes a driving member 23, a first rotating filament-breaking blade 21, and a second rotating filament-breaking blade 22. The first rotating filament-breaking blade 21 is disposed on top of the second rotating filament-breaking blade 22, and the blades of the first rotating filament-breaking blade 21 and the second rotating filament-breaking blade 22 are arranged facing each other. The driving end of the driving member 23 is connected to the first rotating filament-breaking blade 21 and / or the second rotating filament-breaking blade 22 to drive the first rotating filament-breaking blade 21 and / or the second rotating filament-breaking blade 22 to rotate. That is, by driving the driving member 23, the first rotating filament-breaking blade 21 and / or the second rotating filament-breaking blade 22 can be rotated, thereby breaking up the clumps of leaf filaments.

[0052] Specifically, both the first rotating filament-breaking knife 21 and the second rotating filament-breaking knife 22 are arranged in a ring array of multiple cutting blades to facilitate the cutting and breaking up of clumps of leaf filaments during rotation.

[0053] Optionally, the blade edge is wavy to prevent the blade fibers from slipping.

[0054] Optionally, the rotation direction of the first rotating filament cutter 21 is opposite to that of the second rotating filament cutter 22, which makes it easier to cut and break up the clumps of filaments.

[0055] Optionally, the distance between the first rotating filament-breaking knife 21 and the second rotating filament-breaking knife 22 is 1mm-3mm, and the operating speed is 30r / min-100r / min, which can achieve better cutting and breaking of the clump of leaf filaments.

[0056] Optionally, one drive unit 23 is provided, and the output end of the drive unit 23 is connected to the first rotating wire breaking cutter 21 and the second rotating wire breaking cutter 22, wherein the rotation direction can be changed by the transmission assembly. Alternatively, two drive units 23 are provided, and the output ends of the two drive units 23 are respectively connected to the first rotating wire breaking cutter 21 and the second rotating wire breaking cutter 22, and the rotation directions of the two drive units 23 are opposite.

[0057] Optionally, the driving component 23 can be a driving structure such as a motor, which is not specifically limited here.

[0058] Furthermore, the leaf filament shuffling component 20 also includes a baffle mesh 24, which is spaced at the bottom of the second rotating filament breaking knife 22. The baffle mesh 24 has multiple through holes 241, the cross-sectional area of ​​which is S. The minimum cross-sectional area of ​​the leaf filament is S1, and the maximum cross-sectional area of ​​the stem is S2, where S2≤S≤S1. This allows for the discharge of the stem and the retention of the pure leaf filament, thereby shuffling it and allowing it to be air-separated again to the discharge port 101.

[0059] Optionally, the shape of the through hole 241 can be square, circular, etc., and no specific limitation is made here.

[0060] For example, in this embodiment, the wire-blocking mesh 24 is a mesh structure with square through holes 241. The diameter of the square through holes 241 is in the range of 24.5mm-45mm, which can realize the discharge of the stems and the blocking of clumps of tobacco.

[0061] Optionally, the distance between the bottom of the wire-blocking mesh 24 and the second rotating wire-breaking knife 22 is 3mm-5mm to avoid obstruction and affect the rotation of the second rotating wire-breaking knife 22.

[0062] Please return to the reference. Figure 1 and Figure 2 In this embodiment, the vertical air separator for leaf blades further includes a feed pipe 30, which is disposed at the feed inlet of the air separator chamber 10. The feed pipe 30 includes a feed end 31 and an extension end 32. The feed end 31 can be connected to an external feeding device, and the extension end 32 is disposed in the middle of the first air separator chamber 11 to supply leaf blades to the air separator chamber 10. The feed pipe 30 is provided for the feeding of leaf blades, thereby realizing the entry of materials.

[0063] Optionally, the cross-sectional area of ​​the feed pipe 30 gradually decreases from the feed end 31 to the extension end 32, specifically by gradually decreasing the change in the movement speed of the blades. This arrangement avoids the wind speed and air volume of the feed pipe 30 affecting the air separation inside the air separation chamber 10, thereby improving the air separation effect and reliability of the blade vertical air separator.

[0064] Optionally, the feed end 31 of the feed pipe 30 has an elliptical cross-sectional shape, while other positions are circular, which facilitates feeding.

[0065] Furthermore, the vertical air separator also includes an airflow diversion shuttle 40, which is located at the bottom of the second air separation chamber 12. The airflow shuffling component 20 is sleeved on the outer periphery of the airflow diversion shuttle 40. The airflow diversion shuttle 40 is used to divert the airflow in the second air separation chamber 12 to prevent the stalks from being mixed into the airflow due to the high wind speed in the second air separation chamber 12, thereby improving the air separation effect.

[0066] Optionally, since the blade shuffling assembly 20 is fitted around the outer periphery of the airflow diversion shuttle 40, the drive component 23 and other structures in the blade shuffling assembly 20 can be directly installed inside the airflow diversion shuttle 40. This not only improves space utilization but also does not affect the airflow velocity in the second air separation chamber 12, thereby improving the air separation effect and reliability of the blade vertical air separator.

[0067] Optionally, the airflow splitter 40 has a spindle-shaped structure to achieve the function of splitting the airflow.

[0068] Furthermore, the vertical air separator for blades also includes a blade diverter 50, which is disposed within the first air separation chamber 11 and located at the bottom of the feed inlet of the air separation chamber 10. This arrangement, on the one hand, reasonably controls the air separation speed and air separation area of ​​the first air separation chamber 11, thereby solving the problem of wind speed variation caused by the direct insertion of the feed pipe 30 into the first air separation chamber 11; on the other hand, it can also divert the blades, thereby changing the direction of blade movement and improving the air separation effect of the first air separation chamber 11.

[0069] Optionally, the blade splitter 50 has a top conical structure and a bottom semi-spindle structure to achieve the splitting of the blades and the splitting of the airflow in the first air selection chamber 11.

[0070] The following describes some preferred specific embodiments to illustrate the vertical air separator with blades.

[0071] Example 1

[0072] Please refer to Figure 1 and Figure 6 This embodiment provides a blade-filament vertical air separator, which includes all the structures described above, with a blade filament flow rate of 5000 kg / h. The design parameters of this blade-filament vertical air separator are as follows: Figure 6 As shown.

[0073] Specifically, the vertical air separator for leaf filaments includes an air separation chamber 10, a leaf filament shuffling assembly 20, a feed pipe 30, an airflow diversion shuttle 40, and a leaf filament diversion shuttle 50. The wind speed and air separation area of ​​the first air separation chamber 11 are further controlled by the leaf filament diversion shuttle 50 to improve the air separation effect of the first air separation chamber 11.

[0074] Example 2

[0075] Please refer to Figure 2 and Figure 7 This embodiment provides a vertical air separator with blades. The main difference between this vertical air separator and Embodiment 1 is that it does not have a blade diverter shuttle 50, and its blade flow rate is 5000 kg / h. The design parameters of this vertical air separator are as follows: Figure 7 As shown.

[0076] Specifically, the vertical air separator for leaf filaments includes an air separation chamber 10, a leaf filament shuffling assembly 20, a feed pipe 30, and an airflow diversion shuttle 40. The wind speed and air separation area of ​​the first air separation chamber 11 are further controlled by changing the height and diameter of the first air separation chamber 11, that is, reducing the air separation area of ​​the first air separation chamber 11 to improve the air separation effect of the first air separation chamber 11.
