Description

Technical Field

[0001] This utility model relates to the technical field of cigarette production equipment, specifically to a tobacco material separation device. Background Technology

[0002] Using negative pressure dust collection for tobacco shred transport is a common technique in the tobacco forming process. However, some tobacco shreds may remain untransported during this process. These residual shreds, after passing through the negative pressure dust collector and entering the dust collection fan or system, become fragmented and contaminated, rendering them unusable and resulting in tobacco loss. Existing technologies address this problem by installing filtration devices in the channel, using sieving and separation methods to separate the tobacco shreds. However, these separation methods are ineffective and prone to clogging. Utility Model Content

[0004] This utility model proposes a tobacco material separation device, including a main body with an air inlet and an air outlet. A cavity flow channel is provided inside the main body. The air inlet and air outlet are respectively connected to the two ends of the cavity flow channel.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0022] Please see Figures 1 to 5 A tobacco material separation device includes a main body 10, within which a cavity flow channel 101 is provided. The cavity flow channel 101 is a curved channel, including a first sidewall 102 and a second sidewall 103 disposed opposite to each other. The main body 10 is provided with an air inlet 11 and an air outlet 12 respectively connecting the two ends of the cavity flow channel 101. Both the first sidewall 102 and the second sidewall 103 are curved surfaces curving in the same direction. The second sidewall 103 is located outward relative to the first sidewall 102. A discharge port 104 is provided on the second sidewall 103 near the air outlet 12, and the discharge port 104 is connected to a receiving box. The airflow carrying tobacco material enters the cavity flow channel 101 through the air inlet 11, is guided upward by the second sidewall 103, and is discharged from the discharge port 104, thereby achieving the separation of airflow and material.

[0023] In this embodiment, the first sidewall 102 is a curved surface that bends in one direction. The second sidewall 103 is opposite to the first sidewall 102 and bends in the same direction as the first sidewall 102. The first sidewall 102 and the second sidewall 103 are connected on both sides by two opposite side plates to form a cavity flow channel 101. The second sidewall 103 is located on the outer side relative to the first sidewall 102. When the airflow enters the cavity flow channel 101 from the air inlet 11, guided by the shape of the cavity flow channel 101, the gas moves towards the outlet. Under the guidance of the second sidewall 103 and the first sidewall 102, the tobacco material in the airflow moves close to the second sidewall 103. Therefore, an outlet 104 is opened on the second sidewall 103. After the tobacco moving along the second sidewall 103 moves to the outlet 104, it leaves the cavity flow channel 101 from the outlet 104, thus realizing the separation of materials in the airflow.

[0024] Furthermore, the middle of the cavity flow channel 101 has the smallest cross-sectional area. Along the direction from the middle of the cavity flow channel 101 to the air outlet 12, the cross-sectional area of ​​the cavity flow channel 101 gradually decreases, so that during the movement of the airflow carrying the material in the cavity flow channel 101, the airflow has a higher flow velocity at the position with the smallest cross-sectional area, and the airflow is further accelerated, providing power for the movement of the material, so that the material in the airflow moves closer to the second side wall 103. Along the direction from the air inlet 11 to the middle of the cavity flow channel 101, the cross-sectional area of ​​the cavity flow channel 101 gradually increases, and the distance between the first side wall 102 and the second side wall 103 increases. The accelerated material moves closer to the second side wall 103, and the airflow moves towards the air outlet 12, improving the separation effect of airflow and material.

[0025] The discharge port 104 is located on the second side wall 103 and near the air outlet 12. A discharge pipe 20 is provided at the discharge port 104. The discharge pipe 20 is located outside the cavity flow channel 101 and is connected to a receiving box to collect the separated material. The receiving box is a sealed container, and the discharge pipe 20 and the discharge port 104 are sealed together, as are the discharge pipe 20 and the receiving box. The airflow only moves within the cavity flow channel 101 to ensure effective material separation.

[0026] The receiving box is located below the discharge port 104. Preferably, the discharge pipe 20 includes a baffle 21, which is connected to the upper end of the discharge port 104. The baffle 21 has an arc-shaped cross section and extends downward to guide the material discharged from the discharge port 104 downward into the receiving box.

[0027] A guide plate 13 is provided at the discharge port 104. The guide plate 13 is located inside the cavity flow channel 101 and is connected to the upper end of the discharge port 104. The guide plate 13 is inclined and the distance between the guide plate 13 and the second side wall 103 gradually increases from the air outlet 12 to the air inlet 11. The tail end of the guide plate 13 is closer to the first side wall 102 than its head end. The airflow moves in the cavity flow channel 101, is guided and accelerated by the first side wall 102 and the second side wall 103, and the material moves close to the second side wall 103. When the material moves to the vicinity of the discharge port 104, the guide plate 13 forms a stop on the front side of the material movement, guiding the material moving close to the second side wall 103 to the discharge port 104. The material is discharged through the discharge port 104 and enters the receiving box downward through the baffle 21, completing the separation of airflow and material.

[0028] In this application, the main body 10 is connected to a dust removal device, which is a vacuum negative pressure dust removal device. In order to ensure the airflow balance inside the cavity flow channel 101, the area of ​​the air inlet 11 is the same as the area of ​​the air outlet 12.

[0029] In this embodiment, the main body 10 is a ring-shaped shell structure with an internal cavity flow channel 101. The central ring is eccentrically oriented downward relative to its outer ring contour, so that the cavity flow channel 101 has the smallest cross-sectional area in the middle. The cross-sectional area of ​​the cavity flow channel 101 gradually increases from decreasing to increasing, providing acceleration for material movement and facilitating the separation of material from airflow. The main body 10 has a cross-section, with the air inlet 11 and the air outlet 12 located on the cross-section. The air inlet 11 and the air outlet 12 are respectively located at both ends of the cavity flow channel 101 and are connected only through the cavity flow channel 101. Since the main body 10 is in the shape of a ring in this embodiment, the middle ring is eccentric relative to the outer circle contour. In order to ensure that the air inlet 11 and the air outlet 12 have the same area, an isolation plate 14 is provided at the air outlet 12. The isolation plate 14 is located in the cavity flow channel 101. The lower end of the isolation plate 14 is connected to the first side wall 102, and its upper end is connected to the air outlet 12 to change the area of ​​the air outlet 12.

[0030] A connecting seat 30 is provided on the cross-section, and an air inlet pipe 31 and an air outlet pipe 32 are provided on the connecting seat 30. The connecting seat 30 is connected to the main body 10. The air inlet pipe 31 is connected to the air inlet 11, and the air outlet pipe 32 is connected to the air outlet 12. The airflow mixed with material enters the main body 10 through the air inlet pipe 31, and the material and airflow are separated by the main body 10. The separated material enters the receiving box, and the separated airflow is discharged from the air outlet pipe 32.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
