Description

Technical Field

[0001] This invention relates to the field of cigarette making machine technology, and more particularly to a dust removal device. Background Technology

[0002] The ZJ118 cigarette rolling machine is a cigarette rolling equipment independently developed by Changde Tobacco Machinery. It operates at a speed of 8,000 cigarettes per minute and is a major cigarette production equipment for domestic cigarette manufacturers.

[0003] The fluidized bed component in this equipment is a crucial part of tobacco feeding, primarily conveying tobacco shreds and separating stems via jet airflow. The fluidized bed component includes a fan, fluidized bed, gas distribution boxes, primary separator, cyclone dust collector, and connecting pipes. Gas distribution boxes are located at both ends of the fluidized bed, connected by pipes. The right-side gas distribution box connects to the fan outlet, while the fan inlet connects to the cyclone dust collector, which is connected to the area above the fluidized bed via pipes. The primary separator is located behind the fluidized bed and communicates with the gas distribution boxes on both sides. Positive pressure airflow generated by the fan enters both gas distribution boxes. The fluidized bed and primary separator, connected to the gas distribution boxes, simultaneously receive this positive pressure airflow. This positive pressure airflow passes through the primary separator and fluidized bed nozzles, forming a jet airflow that sorts and conveys the tobacco shreds. Dust particles in the tobacco shreds, under the negative pressure above the fluidized bed, enter the cyclone dust collector. After being removed by the cyclone dust collector, the dust enters the fan inlet, forming an internal airflow circulation loop.

[0004] Because the airflow is constantly circulating internally, its temperature gradually increases, causing moisture in the tobacco to evaporate and reducing its moisture content, thus affecting the quality of the cigarette. Furthermore, the lower moisture content makes the tobacco lighter and more brittle, significantly increasing the breakage rate during transport. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a dust removal device to solve the problem that the temperature of the circulating airflow inside the fluidized bed component gradually increases, affecting the quality of cigarettes.

[0006] The present invention solves the above-mentioned technical problems through the following technical means:

[0007] A dust removal device includes a cylinder, a cone, and a dust hopper. Several heat dissipation components are installed on the cone. Each heat dissipation component includes heat dissipation fins and several heat dissipation columns. The heat dissipation columns are fixedly connected to the heat dissipation fins. Several through holes are opened on the cone. The heat dissipation fins are located on the outside of the cone. The heat dissipation columns pass through the through holes and are located inside the cone. Heat inside the cone can be transferred to the outside of the cone through the heat dissipation columns and heat dissipation fins.

[0008] Furthermore, the heat dissipation column is provided with multiple dust collection grooves, which are used to capture small dust particles in the airflow.

[0009] Furthermore, the through hole is provided with multiple protrusions, each of which corresponds to a dust collection groove. The protrusions are engaged in the dust collection grooves, and when the heat dissipation column moves outward toward the cone, the protrusions can scrape away the dust in the dust collection grooves.

[0010] Furthermore, a driving assembly is provided outside the cone, which is used to drive several heat sinks to move synchronously. When the heat sinks move, they can drive the heat dissipation column to move.

[0011] Furthermore, the driving assembly includes a driving rod and multiple driving rings, all of which are fixedly connected to the driving rod. The heat sink has multiple driving slots, each corresponding to a driving ring. The driving rings pass through the driving slots. When the driving rod moves the driving rings upward, the driving rings drive the heat sink and heat dissipation column to move away from the cone through the driving slots. When the driving rod moves the driving rings downward, the driving rings drive the heat sink and heat dissipation column to move closer to the cone through the driving slots.

[0012] Furthermore, the cylinder is provided with a mounting ear, and the top of the drive rod is slidably connected to the mounting ear.

[0013] Furthermore, a limit block is provided on the drive rod, and a spring is sleeved on the drive rod. One end of the spring is fixedly connected to the mounting ear, and the other end is fixedly connected to the limit block.

[0014] Furthermore, a sealing groove is provided inside the through hole, and a sealing ring is provided inside the sealing groove.

[0015] Furthermore, the top of the heat sink is provided with an arc-shaped surface.

[0016] The beneficial effects of this invention are:

[0017] 1. The heat is absorbed by the heat dissipation column and then transferred to the heat dissipation fins, thereby transferring the heat from inside the cone to the outside of the cone, reducing the heat inside the cone, reducing the evaporation of moisture in the tobacco, and ensuring the quality of the tobacco.

[0018] 2. By setting up a dust collection trough, when the airflow flows through the heat dissipation column, small dust particles in the airflow are captured by the dust collection trough, thereby reducing the amount of small dust particles in the airflow. Large dust particles are forced to leave the airflow under the centrifugal force when the airflow rotates and slide down along the cyclone body wall into the ash hopper, reducing the dust in the fluidized bed components and effectively reducing the occurrence of nozzle blockage in the fluidized bed components due to dust deposition.

[0019] 3. By setting up a drive assembly, when the machine stops, moving the drive rod can drive the drive ring to move. The drive ring cooperates with the drive groove, thereby driving the heat sink and heat sink column to move. When the heat sink column moves, the protrusions in the through hole scrape the dust in the dust collection tank so as to capture small dust particles in the airflow again. The scraped dust slides down and accumulates in the ash hopper for easy cleaning. Attached Figure Description

[0027] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures, and should not be construed as limiting the present invention. In order to better illustrate the embodiments of the present invention, some components in the figures may be omitted, enlarged, or reduced, and do not represent the actual product size; it is understandable for those skilled in the art that some well-known structures and their descriptions may be omitted in the figures.

Therefore, the terms used to describe positional relationships in the figures are only for illustrative purposes and should not be construed as limiting this invention. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0029] like Figures 1-3 As shown, a dust removal device of the present invention includes a cylindrical cylinder 11, a conical cylinder 12 and an ash hopper 13. A plurality of heat dissipation components are installed on the conical cylinder 12. The plurality of heat dissipation components are arranged at equal angles along the circumference of the conical cylinder 12. The heat dissipation components are used to transfer the heat in the conical cylinder 12 to the outside of the conical cylinder 12, thereby reducing the evaporation of moisture in the tobacco and ensuring the quality of the tobacco.

[0030] Understandably, an air inlet 14 is provided on one side of the cylinder 11 for airflow to enter the cylinder 11, and an air outlet 15 is provided at the top of the cylinder 11 for airflow to exit the cylinder 11. The air inlet 14 of the cyclone dust collector is connected to the upper part of the fluidized bed through a pipe, and the air outlet 15 of the cyclone dust collector is connected to the inlet of the fan. The airflow in the fluidized bed enters the cyclone dust collector from the air inlet 14. After the airflow enters the cylinder 11, it forms a high-speed rotating airflow in the cone 12. Due to the centrifugal force, the particles are subjected to a spiral force, generating a large centrifugal force against the wall of the cone 12. Under the action of the centrifugal force of the cone 12 wall, large particles are forced to leave the airflow, slide down the cone 12 wall, and finally collect in the ash hopper 13 at the bottom of the cone 12. The dust-removed airflow is drawn into the fan from the top of the cone 12 through the air outlet 15.

[0031] Specifically, the heat dissipation assembly includes a heat sink 21 and several heat dissipation columns 22. The heat dissipation columns 22 are fixedly connected to the heat sink 21. In this embodiment, the heat sink 21 is perpendicular to the conical surface of the cone 12 and arranged along the inclined direction of the conical surface. The heat dissipation columns 22 are integrally formed with the heat sink 21 and are arranged at equal intervals along the inclined direction of the heat sink 21, and the heat dissipation columns 22 are horizontally set. In practice, other methods such as welding the heat dissipation columns 22 to the heat sink 21 can also be selected according to the actual situation to achieve a fixed connection between the heat dissipation columns 22 and the heat sink 21. In this embodiment, the integral forming method can effectively ensure the heat transfer between the heat dissipation columns 22 and the heat sink 21. Several through holes 121 are opened on the cone 12. The heat sink 21 is located on the outside of the cone 12, and the heat dissipation columns 22 pass through the through holes 121 and are located inside the cone 12. The heat inside the cone 12 is transferred to the outside of the cone 12 through the heat dissipation columns 22 and the heat sink 21.

[0032] It should be noted that the heat sink 22 and the heat sink 21 are preferably made of metals such as copper and aluminum, which have excellent thermal conductivity and are inexpensive.

[0033] In this embodiment, a sealing groove 122 is provided inside the through hole 121, and a sealing ring 123 is provided inside the sealing groove 122. The sealing ring 123 seals the gap between the through hole 121 and the heat dissipation column 22, preventing external airflow from entering the cone 12 through the gap. This ensures the dust removal effect of the cyclone dust collector.

[0034] In this embodiment, the heat dissipation column 22 is provided with multiple dust collection grooves 221, which are used to capture small dust particles in the airflow. When the airflow flows through the heat dissipation column 22, the small dust particles in the airflow are captured by the dust collection grooves 221, thereby reducing the amount of small dust particles in the airflow. Large dust particles are forced to leave the airflow under the centrifugal force when the airflow rotates, and slide down along the cyclone body wall into the dust hopper 13, reducing the dust in the fluidized bed component and effectively reducing the occurrence of nozzle blockage due to dust deposition in the fluidized bed component.

[0035] Multiple protrusions 124 are provided inside the through hole 121, each corresponding to a dust collection groove 221. The protrusions 124 are engaged within the dust collection groove 221. A drive assembly is provided outside the cone 12, which drives several heat sinks 21 to move synchronously. When the heat sinks 21 move, they can drive the heat dissipation column 22 to move. When the heat dissipation column 22 moves outward from the cone 12, the protrusions 124 can scrape the dust in the dust collection groove 221. Small dust particles can accumulate into large dust particles in the dust collection groove 221. When the protrusions 124 scrape the small dust particles from the dust collection groove 221, they can fall downward into the dust hopper 13 for easy cleaning.

[0036] Specifically, the drive assembly includes drive rods 31 and multiple drive rings 32, all of which are fixedly connected to the drive rods 31. Multiple drive slots 211 are provided on the heat sink 21, each corresponding to a drive ring 32, with the drive ring 32 passing through the drive slot 211. In this embodiment, four drive rods 31 and three drive rings 32 are provided, with each of the three drive rings 32 welded to one of the four drive rods 31, effectively ensuring the stability of the movement of the heat sink 21 and the heat dissipation column 22. In practice, other methods such as riveting the drive rings 32 to the drive rods 31 or integral molding can also be selected to achieve a fixed connection between the heat dissipation column 22 and the heat sink 21, depending on the actual situation. When the drive rods 31 drive the drive rings 32 upwards, the drive rings 32 drive the heat sink 21 and the heat dissipation column 22 away from the cone 12 through the drive slots 211. During this process, the protrusions 124 scrape away small dust particles from the dust collection groove 221. When the drive rod 31 drives the drive ring 32 to move downward, the drive ring 32 drives the heat sink 21 and the heat sink column 22 to move closer to the cone cylinder 12 through the drive groove 211 until the heat sink 21 presses the sealing ring 123 tightly.

[0037] It should be noted that the top of the heat sink 21 is provided with an arc-shaped surface to reduce the volume occupied by the top of the heat sink 21, so as to install the cyclone dust collector of this embodiment.

[0038] In this embodiment, a mounting ear 111 is provided on the cylinder 11, and the top of the drive rod 31 is slidably connected to the mounting ear 111. The mounting ear 111 is used to limit the drive rod 31 and prevent the limit rod from moving arbitrarily. A limit block 311 is provided on the drive rod 31, and a spring 312 is sleeved on the drive rod 31. One end of the spring 312 is fixedly connected to the mounting ear 111, and the other end is fixedly connected to the limit block 311. The spring 312 is a compression spring, which is used to provide preload force to the drive rod 31, so that the drive ring 32 is located at the bottom of the drive groove 211, thereby ensuring that the heat dissipation column 22 is inserted into the cone cylinder 12 and that the heat dissipation fin 21 presses the sealing ring 123 tightly to ensure the sealing effect.

[0039] The working principle of this invention is as follows:

[0040] When the fan connected to the outlet 15 of the cyclone dust collector is working, it creates a negative pressure in the cyclone dust collector, which in turn draws air from the fluidized bed assembly through the pipe from the inlet 14. After the air is purged of dust in the cyclone dust collector, it is drawn into the fan from the top of the cone 12 through the outlet 15, and then blown into the fluidized bed assembly by the fan to form a circulating airflow.

[0041] When the airflow passes through the cone 12, the heat in the airflow is absorbed by the heat dissipation column 22, and the heat dissipation column 22 then transfers the heat to the heat dissipation fin 21, thereby transferring the heat inside the cone 12 to the outside of the cone 12, reducing the heat inside the cone 12, reducing the evaporation of moisture in the tobacco, and ensuring the quality of the tobacco.

[0042] As the airflow passes through the heat dissipation column 22, small dust particles in the airflow are captured by the dust collection trough 221, while large dust particles are forced away from the airflow by the centrifugal force of the rotating airflow and slide down the cyclone body wall into the ash hopper 13. When the machine stops, the drive rod 31 is moved upward, which drives the drive ring 32 to move upward. The drive ring 32 drives the heat dissipation fins 21 and the heat dissipation column 22 to move away from the cone 12 through the drive groove 211. During this process, the protrusion 124 scrapes away the small dust particles in the dust collection trough 221. Furthermore, the small dust particles accumulate into large dust particles in the dust collection trough 221. When the protrusion 124 scrapes away the small dust particles in the dust collection trough 221, they can fall downward into the ash hopper 13 for easy cleaning.

[0043] Then, the drive rod 31 is moved downward, and the drive rod 31 drives the drive ring 32 to move downward. The drive ring 32 drives the heat sink 21 and the heat sink column 22 to move closer to the cone cylinder 12 through the drive groove 211 until the heat sink 21 presses the sealing ring 123 to seal.
