[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides an example of a non-smoke substance filtration device for flue-cured tobacco. In this embodiment, the filtration device includes a mounting platform 1, which includes an outer frame 11. An inner frame 12 is fixedly connected to the inner side of the outer frame 11. An outer rod 21 is placed on top of the inner frame 12 to facilitate support for the mesh frame 2. Four sets of support legs 13 are fixedly connected to the bottom of the outer frame 11 and the inner frame 12. A horizontal bar 14 is fixedly connected between adjacent sets of support legs 13, and a vertical bar 15 is fixedly connected between the horizontal bar 14 and the outer frame 11. The horizontal bar 14 and the vertical bar 15 are used to increase structural strength and prevent deformation of the mounting platform 1. Multiple sets of support rods 16 are fixedly connected in the inner frame 12. The support rods 16 are used to support the bottom of the mesh frame 2 and prevent the mesh frame 2 from deforming due to heavy pressure.

[0025] Furthermore, the aforementioned filtration device includes a mesh frame 2 installed on the mounting platform 1. The mesh frame 2 includes a "U"-shaped structure composed of four sets of outer rods 21. Multiple sets of partition rods 22 are fixedly connected between two sets of oppositely arranged outer rods 21. Connecting rods 23 are fixedly connected to both sides of the partition rods 22. The partition rods 22 and the connecting rods 23 are equidistantly arrayed to support the tobacco leaves and to filter non-smoke substances through the holes formed.

[0026] Furthermore, the aforementioned filtration device also includes a collection box 3 located below the mesh frame 2. The bottom of the collection box 3 is inclined to facilitate the movement of non-smoke substances under the influence of gravity. A collection box 4 is located below the lowest point of the collection box 3. The collection box 4 is used to collect non-smoke substances for centralized processing. A through hole 31 is provided at the bottom of the collection box 3, located directly above the collection box 4. This allows the collection box 3 to catch non-smoke impurities that leak from the mesh frame 2 and collect them in the collection box 4 for centralized processing.

[0027] For details, please refer toFigure 2 And Figure 3 The filter device further comprises a cleaning assembly 5 mounted on the collecting box 3, and the cleaning assembly 5 is used for facilitating the discharge of the non-smoke substance in the collecting box 3. The cleaning assembly 5 comprises four groups of first fixed plates 51 fixedly connected to the bottom of the collecting box 3, and a limiting rod 52 is fixedly connected between each group of oppositely arranged first fixed plates 51. The limiting rod 52 is slidably connected with a limiting block 53, and the two groups of limiting blocks 53 are fixedly connected with a moving frame 54. The moving frame 54 is arranged in a "N" shape, and moves stably under the limiting action of the limiting block 53 and the limiting rod 52. The moving frame 54 is fixedly connected with a mounting plate 55, and the mounting plate 55 is arranged on one side of the collecting box 3. A first servo motor 56 is arranged on the side of the mounting plate 55 away from the collecting box 3 and is mounted on the moving frame 54. The output end of the first servo motor 56 penetrates through the mounting plate 55 and is fixedly connected with a rotating rod 57. The first servo motor 56 is used for driving the rotating rod 57 to move after being started. A brush roller 58 is mounted on the rotating rod 57 and is arranged in the inside of the collecting box 3. The rotating rod 57 drives the brush roller 58 to rotate synchronously when rotating, so as to clean the non-smoke impurities at the bottom of the collecting box 3 and help the non-smoke impurities to be concentrated in the concentrating box 4. Meanwhile, the slow rotation of the brush roller 58 avoids dust raising. Sliding grooves 32 are arranged on both sides of the collecting box 3, and the rotating rod 57 is in sliding cooperation with the sliding grooves 32. The arrangement of the sliding grooves 32 facilitates the movement of the rotating rod 57 and the brush roller 58. A threaded sleeve 59 is fixedly connected to the bottom of the moving frame 54 and drives the moving frame 54 to move synchronously when moving. A threaded rod 510 is threadedly connected in the threaded sleeve 59, and second fixed plates 511 are rotatably connected to both ends of the threaded rod 510. The two groups of second fixed plates 511 are fixedly connected to the bottom of the collecting box 3. The threaded rod 510 remains in place and rotates, and can drive the threaded sleeve 59 to move along the length direction of the threaded rod 510 when the threaded rod 510 rotates. A mounting bracket 512 is mounted on the side of the collecting box 3 away from the through hole 31, and a second servo motor 513 is mounted in the mounting bracket 512. The output end of the second servo motor 513 is fixedly connected with the threaded rod 510, and the position of the second servo motor 513 is fixed, so as to drive the threaded rod 510 to rotate.

[0028] In the process of placing the tobacco leaves on the net rack 2, the tobacco leaves are supported by the partition rods 22 and the connecting rods 23, and the holes formed between them are used for primary filtering of the non-smoke substance. The non-smoke substance falls downward after passing through the holes. The falling non-smoke substance is caught by the collecting box 3 arranged below the net rack 2. Since the bottom of the collecting box 3 is arranged in an inclined manner, the non-smoke substance moves to the lowest position of the collecting box 3 under the action of gravity. The concentrating box 4 below the lowest position of the collecting box 3 further collects the non-smoke substance in the collecting box 3 through the through hole 31 arranged at the bottom of the collecting box 3, so as to be conveniently concentrated and treated subsequently.

[0029] In order to promote the discharge of non-smoking matter in the collection box 3, the cleaning assembly 5 works. The second servo motor 513 is started, and the output end drives the threaded rod 510 to rotate. Since the threaded sleeve 59 is threadedly connected with the threaded rod 510, and the threaded sleeve 59 is fixedly connected at the bottom of the moving frame 54, the rotation of the threaded rod 510 drives the threaded sleeve 59 to move along the length direction of the threaded rod 510, thereby stably moving the moving frame 54 under the limiting action of the limiting block 53 and the limiting rod 52. The mounting plate 55 fixedly connected with the moving frame 54 moves synchronously with the moving frame 54, and the first servo motor 56 mounted on the moving frame 54 also moves synchronously.

[0030] The first servo motor 56 is started, and the output end drives the rotating rod 57 to rotate, and the brush roller 58 mounted on the rotating rod 57 rotates synchronously. The rotating rod 57 is slidably connected with the sliding groove 32 formed on both sides of the collection box 3. During the movement of the moving frame 54, the brush roller 58 slowly rotates inside the collection box 3, sweeps the non-smoking impurities on the bottom of the collection box 3, and sweeps them to the direction of the concentrating box 4, thereby avoiding dust raising and helping the non-smoking matter to be concentrated in the concentrating box 4, and completing the whole work flow of filtering, collecting and cleaning the non-smoking matter.

[0031] The specific embodiments of the utility model are described in detail above, but it is only as an example, and the utility model is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modification or replacement to the utility model is also within the scope of the utility model, therefore, equivalent transformation, modification, improvement, etc. made without departing from the spirit and principle range of the utility model should be covered in the scope of the utility model.
