Abstract
Description
Technical Field
[0001] The present application relates to the technical field of cigarette production, and in particular to a fluidized bed device and a tobacco production system. Background Art
[0002] In the process of cigarette production, a fluidized bed is usually required to transport tobacco. The fluidized bed has an arc surface for tobacco to flow. When tobacco flows along the arc surface, the friction of the tobacco flow will cause the area near the nozzle at the end of the arc surface in the direction of tobacco flow to wear out, making it uneven and not smooth enough, resulting in unsmooth tobacco flow and unstable cigarette weight. Therefore, the entire nozzle of the fluidized bed needs to be replaced, which leads to higher production and a more complicated replacement process.
[0003] It should be noted that the statements in this background technology section only provide background technology related to the present application and do not necessarily constitute prior art. Utility Model Content

The device may also be positioned in other different ways, and the spatially relative descriptions used here are interpreted accordingly.
[0027] refer to Figure 1 and 2The present application provides a fluidized bed device including an air distribution box 01 and a flow channel 02. At least a portion of the flow channel 02 is arranged on the air distribution box 01. The flow channel 02 is used for material flow. The air distribution box 01 is used to spray airflow to the flow channel 02 to provide power for the material during the material flow process. The flow channel 02 includes a common flow channel and a branch flow channel arranged in sequence along the flow direction of the material. The branch flow channel includes a first flow channel 2a and a second flow channel 2b. The first flow channel 2a and the second flow channel 2b extend from the end of the common flow channel in the flow direction along different paths to form two arcuate flow channel surfaces with different extension directions. At least one of the first flow channel 2a and the second flow channel 2b includes a guide portion. The guide portion includes a first guide body 1 and a second guide body 2. The first guide body 1 is arranged on the air distribution box 01. The second flow guide 2 is arranged on the air distribution box 01 and is located downstream of the first flow guide 1 in the flow direction. The first end of the second flow guide 2 is adjacent to the first flow guide 1. The second end of the second flow guide 2 is used to cooperate with the air distribution box 01 to form a terminal nozzle. The terminal nozzle is used to spray air flow to cause the material to flow out of the flow channel 02. The second flow guide 2 includes a mounting base 21 and a guide plate 22. The guide plate 22 is detachably mounted on the mounting base 21 to form a part of the arc flow channel surface.
[0028] The guide plate 22 is configured to be detachable. After the fluidized bed device has been working for a long time, when the surface of the guide plate 22 is worn, only the guide plate 22 needs to be replaced for continued use, and the mounting base 21 can be reused, thereby reducing production costs. In addition, there are fewer parts to be disassembled, and disassembly is convenient and time-saving, which reduces the time for the fluidized bed device to be shut down to replace the guide plate 22, thereby improving the equipment capacity.
[0029] In some embodiments, both the first flow channel 2a and the second flow channel 2b include a guide body, so that after the arcuate flow channel surfaces of the first flow channel 2a and the second flow channel 2b are worn, the guide plate 22 can be quickly replaced without replacing the mounting base 21.
[0030] In some embodiments, the first guide body 1 is detachably mounted on the air distribution box 01. The surface of the first guide body 1 is an arc surface, which is used to cooperate with the guide plate 22 to form an arc-shaped flow channel surface. In addition, there is a first gap at the connection between the first guide body 1 and the second guide body 2, and the gas in the air distribution box 01 can be ejected through the first gap to provide power for the material and promote the material to flow to the end nozzle.
[0031] It is understandable that, in the flow direction of the material, the flow channel 02 may also have a second gap at a position upstream of the first flow guide body 1 , and the gas in the air distribution box 01 may be ejected from the second gap to provide power for the material and cause the material to flow toward the first flow guide body 1 .
[0032] refer to Figure 1The fluidized bed device also includes a negative pressure box 03, which is arranged at the end of the flow direction of the flow channel 02 and is located directly above the end of the flow channel 02 in height. The negative pressure box has two suction ports that generate negative pressure. The direction perpendicular to the width direction Y in the horizontal plane is defined as the length direction X, and the two suction ports are spaced apart in the length direction X. The two suction ports are respectively connected to the ends of the first flow channel 2a and the second flow channel 2b. After the material flows to the common flow channel, it is split and flows to the two suction ports through the first flow channel 2a and the second flow channel 2b respectively. After the material enters the negative pressure box 03 from the two suction ports, it is separated into two columns in the length direction X and transported to the next process in the width direction Y.
[0033] Further, refer to Figure 1 The second flow channel 2b is constructed to extend a longer distance in the length direction X relative to the first flow channel 2a, and the first flow channel 2a and the second flow channel 2b are constructed to allow the material to flow along the arc-shaped flow channel surface and be lifted until the end of the first flow channel 2a and the second flow channel 2b, the flow direction of the material is perpendicular to the horizontal plane and upward. At this time, the end nozzle provides the material with power to continue moving vertically upward, and the suction port cooperates with the end nozzle to allow the material to flow out of the flow channel 02 and enter the negative pressure box 03.
[0034] refer to Figure 3 In some embodiments, the end nozzle includes a plurality of injection slots A disposed at the second end of the mounting base 21 and spaced apart along the width direction Y of the flow channel 02. The air distribution box 01 injects airflow through the plurality of injection slots A to cause the material to flow out of the flow channel 02.
[0035] Such arrangement enables the end of the flow channel 02 to spray airflow in the entire width direction Y to provide power for the material, and can increase the flow rate of the airflow flowing out of the spray slot A to better provide power for the material.
[0036] In some embodiments, the extending direction of the injection slot A is at an angle to the width direction Y. This helps the airflow to act on the material, prompting the material to enter the negative pressure box 03.
[0037] For example, refer to Figure 3 and 4 , the extension direction of the injection slot A can be configured to be perpendicular to the width direction Y. In other embodiments, Figure 5 , the angle between the extension direction of the injection slot A and the width direction Y is an acute angle or an obtuse angle.
[0038] In some embodiments, a plurality of injection slots A are distributed at equal intervals in the width direction Y. This helps to make the airflow distribution more uniform in the entire width direction Y, and improves the uniformity of the effect of the end nozzle on the material.
[0039] refer to Figure 3 and4 In some embodiments, the mounting base 21 includes a front mounting surface 21a and a rear mounting surface 21b. The front mounting surface 21a is used to mount the guide plate 22. The rear mounting surface 21b is used to connect the air distribution box 01. The front mounting surface 21a is an arc-shaped surface, the guide plate 22 is an arc-shaped plate, and the front mounting surface 21a and the guide plate 22 are consistent in shape, so that the guide plate 22 can be well fitted with the front mounting surface 21a, thereby improving the stability of the guide plate 22 after being mounted on the mounting base 21. A mounting groove is provided on the air distribution box 01, and the mounting groove is adapted to the shape of the rear mounting surface 21b, so that the mounting base 21 can be easily mounted on the air distribution box 01.
[0040] refer to Figure 2 In some embodiments, the mounting base 21 is threadedly connected to the guide plate 22. This can simplify the assembly of the guide plate 22 and the mounting base 21, has a simple structure, and has strong stability after assembly. Specifically, a plurality of through holes are provided on the front mounting surface 21a, and the plurality of through holes are spaced apart and penetrate the mounting base 21 in the thickness direction. A plurality of spaced apart threaded cylindrical pins are provided on one surface of the guide plate 22 for cooperating with the front mounting surface 21a. The plurality of cylindrical pins are respectively passed through the plurality of through holes, and the plurality of cylindrical pins are fastened by nuts on one side of the rear mounting surface 21b, thereby completing the installation of the guide plate 22.
[0041] refer to Figure 3 In some embodiments, the mounting base 21 further includes a rear guide surface 21c. The rear guide surface 21c and the rear mounting surface 21b are both planes and are connected to each other at an angle. The first end of the rear guide surface 21c is connected to the rear mounting surface 21b. The second end of the rear guide surface 21c extends toward the end of the front mounting surface 21a away from the first flow guide body 1 so that the thickness of the mounting base 21 gradually decreases from the first end of the rear guide surface 21c to the second end of the rear guide surface 21c. Such a configuration helps the airflow in the air distribution box 01 to be ejected through the ejection slot A in the thickness direction of the mounting base 21, thereby enhancing the power of the ejected airflow and prompting the material to enter the negative pressure box 03.
[0042] In some embodiments, a terminal guide plate is further included. The first end of the terminal guide plate is connected to the rear guide surface 21c. The second end of the terminal guide plate 21c extends in a direction away from the mounting base 21 in a manner parallel to the rear guide surface 21c. The terminal guide plate is used to cooperate with the terminal nozzle to guide the material to flow out of the flow channel 02. The second end of the terminal guide plate extends to the suction port of the negative pressure box, and the terminal guide plate can guide the flow direction of the material, which helps the material enter the negative pressure box 03.
[0043] refer to Figure 3In some embodiments, a recessed area is provided on the surface of the mounting base 21 opposite to the front mounting surface 21a, and the surface of the recessed area constitutes the rear guide surface 21c. The recessed area is provided to facilitate the installation of the end guide plate on the mounting base 21.
[0044] In some embodiments, the surface of the guide plate 22 is coated with a wear-resistant coating. Providing the wear-resistant coating can reduce the wear on the guide plate 22, increase the service life of the guide plate 22, reduce the number of times the fluidized bed device is shut down to replace the guide plate 22, and thus improve the equipment capacity.
[0045] The present application also provides a tobacco production system, comprising the fluidized bed device described above.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present application rather than to limit it. Although the present application has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present application can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present application, which should be included in the scope of the technical solution for protection in the present application.
