[0040] The embodiments of the present invention are written in a progressive manner.

[0041] like Figure 1 As shown, Figure 1 This is a schematic cross-sectional view of a drying device for filter rod particles provided in an embodiment of the utility model. Figure 1 The arrows in the figure are the flow trajectories of the filter rod particles in the drying chamber.

[0042] The utility model provides a drying device for filter rod particles, comprising: a drying chamber 1 provided with a accommodating cavity; an inner cavity 2 fixedly arranged in the accommodating cavity, the inner cavity 2 being provided with a channel extending in a height direction, the channel being used for receiving and conveying particles to be dried blown by hot air; a conveying slide rail 3 arranged between the drying chamber 1 and the inner cavity 2, the conveying slide rail 3 being used for receiving particles to be dried outputted from the channel, and the conveying slide rail 3 extending downward in a spiral shape from the top of the drying chamber 1.

[0043] The current drying devices for filter rod particles often use hot air to blow the particles to be dried upward, so that the particles to be dried are repeatedly boiled and dried inside the chamber. However, this method is inefficient and often takes a long time. In addition, the moisture content of the particles after drying deviates too much from the qualified range. The operator cannot effectively control the drying effect. The undried wet pellets need to be manually picked out, which is cumbersome and time-consuming, seriously affecting the progress of particle production and preparation.

[0044] The utility model provides a drying device for filter rod particles, firstly, it is provided with a drying chamber 1, an inner cavity 2 and a conveying track, wherein a accommodating chamber is provided in the drying chamber 1, the inner cavity 2 is fixedly arranged in the accommodating chamber, a channel is provided in the inner cavity 2, the channel extends along the height direction of the drying chamber 1, the channel is used for receiving and conveying the particles to be dried blown by hot air, the particles to be dried are blown into the channel by the hot air and conveyed along the direction in which the channel extends, the conveying track is arranged between the drying chamber 1 and the inner cavity 2, when the particles to be dried are output from the channel, under the action of gravity and the drying chamber 1, the particles to be dried fall downward, the conveying track is used for receiving the particles to be dried output from the channel, the conveying track extends downward in a spiral from the top of the drying chamber 1, this structure of the conveying track increases the length of the conveying path of the particles to be dried in the drying chamber 1, the particles to be dried can be evenly dried during the conveying process, and the drying efficiency and uniformity are further improved.

[0045] It can be seen that, compared with the prior art, the drying device for filter rod particles in the embodiment of the utility model can be used to dry filter rod particles, the particles are heated evenly, and the drying efficiency is higher.

[0046] Furthermore, the conveying track in the embodiment of the utility model includes conveying blades, and the two sides of the conveying blades are respectively connected to the inner wall of the drying chamber 1 and the outer wall of the inner cavity 2. The conveying blades extend spirally from top to bottom, and a conveying channel is formed between the conveying blades, the inner cavity 2 and the drying chamber 1. Under the action of gravity, the particles to be dried are transported in the conveying channel. Since the particles to be dried are transported to the inner cavity 2 under the action of hot air, the temperature in the drying chamber 1 increases, and the particles to be dried exchange heat with the air in the drying chamber 1, and the conveying channel provides sufficient time for the drying of the particles to be dried. Therefore, the particles to be dried can be heated more evenly and the drying effect is better.

[0047] In the above structure, as one of the embodiments, the shape of the cross section of the channel in the drying device for filter rod particles in the embodiment of the utility model can be circular, and the cross-sectional size of the channel can be of equal diameter. As a preferred embodiment, the cross-sectional size of the channel in the embodiment of the utility model is preferably variable diameter. As a specific embodiment, along the direction in which the channel extends, the cross-sectional size of the channel gradually decreases from both ends toward the middle, and hot air enters the channel from the bottom of the channel. The inlet size is large and gradually decreases in the middle. As the size of the channel decreases, the flow rate of the particles to be dried increases. In order to enable the particles to be dried to fall better on the conveying track, the size of the outlet of the channel becomes larger.

[0048] More preferably, the inner cavity 2 in the embodiment of the utility model is a vertically symmetrical structure, the upper and lower ends of the inner cavity 2 have large openings, and the small size of the middle part can increase the gas flow rate and enhance the drying effect.

[0049] Furthermore, as one of the embodiments, the drying chamber 1 in the embodiment of the utility model includes a lower bin 11 and an upper bin 13, wherein a bottom net 12 is provided at the bottom of the lower bin 11, and the bottom net 12 is used to place the particles to be dried. The upper bin 13 is arranged above the lower bin 11, and the upper bin 13 and the lower bin 11 are detachably sealed and connected, the inner cavity 2 is arranged in the upper bin 13, and the feed port of the channel is aligned with the bottom net 12, and the hot air blows the particles to be dried upward and enters the channel. When the particles to be dried are output from the top of the channel, under the action of gravity and the upper bin 13, the particles to be dried fall into the conveying slide rail 3 and are dried on the conveying slide rail 3. The particles on the conveying slide rail 3 continue to be conveyed, and finally fall on the bottom net 12 and are blown up by the hot air again until the particles to be dried are completely dried.

[0050] In the above structure, as one of the preferred implementations, the upper material bin 13 and the lower material bin 11 in the embodiment of the utility model adopt a split structure, which is more convenient for cleaning.

[0051] Furthermore, as one of the implementation modes, the drying device for filter rod particles in the embodiment of the utility model also includes a hot air supply mechanism 4 and an air outlet 14, wherein the hot air supply mechanism 4 is arranged below the bottom net 12, and the hot air supply mechanism 4 is used to blow up the particles to be dried and send them into the channel. In order to avoid the continuous increase of air pressure in the drying chamber 1, an air outlet 14 is arranged at the top of the upper bin 13, which can make the air in the drying chamber 1 circulate and achieve a better drying effect.

[0052] In the above structure, as one of the implementation modes, the top surface of the loading bin 13 in the embodiment of the utility model is preferably in an arc shape.

[0053] Furthermore, as one of the more preferred embodiments, in order to prevent the particles to be dried blown up by the hot air from clogging the air outlet 14, the drying chamber 1 in the embodiment of the utility model also includes a baffle 15 arranged in the upper bin 13, the baffle 15 is arranged above the inner cavity 2, and the baffle 15 is located below the air outlet 14. The baffle 15 can prevent the particles to be dried from moving further upward, so that the particles to be dried can fall downward. In addition, since the baffle 15 is a mesh structure, the air can enter the top of the upper bin 13 through the baffle 15 and be discharged through the air outlet 14.

[0054] Furthermore, as one of the embodiments, the drying chamber 1 in the embodiment of the utility model further includes a fixed structure and a sealing member, wherein the fixed structure is arranged between the upper bin 13 and the lower bin 11, and the upper bin 13 and the lower bin 11 can be detached through the fixed structure, and the fixed structure has an opening device and a closing device, and when the fixed structure is in an open state, the lower bin 11 is separated from the upper bin 13, and the particles to be dried can be added to the bottom net 12 of the lower bin 11, and the particles that have been dried on the bottom net 12 of the lower bin 11 can also be collected, and when the fixed structure is in a closed state, the top surface of the lower bin 11 fits with the bottom surface of the upper bin 13, and the particles to be dried can be dried. The sealing member is arranged on the bottom surface of the upper bin 13, and when the fixed structure is in a closed state, the upper bin 13 is sealed and connected with the lower bin 11, and the drying effect is better.

[0055] In the above structure, as one of the implementation modes, the fixed structure in the embodiment of the utility model includes a driving member, and the telescopic end of the driving member is used to push the lower material bin 11 to move toward the upper material bin 13. When it is necessary to load or unload the particles on the bottom net 12 of the lower material bin 11, the telescopic end of the driving member drives the lower material bin 11 to move away from the upper material bin 13. When drying is required, the telescopic end of the driving member drives the lower material bin 11 to move toward the upper material bin 13 until the top surface of the lower material bin 11 is in contact with the bottom surface of the upper material bin 13.

[0056] Furthermore, the driving component in the embodiment of the present invention includes but is not limited to any one of a hydraulic driving component, a pneumatic driving component and a motor.

[0057] In the above structure, in order to avoid the phenomenon of misalignment between the upper bin 13 and the lower bin 11, that is, the bottom surface of the upper bin 13 and the top surface of the lower bin 11 are not completely fitted, so that the wet pellets are placed on the edge protrusion during the boiling drying process, resulting in ineffective drying. In order to avoid this situation, as one of the implementation methods, a limiter 16 is provided on the outer side of the upper bin 13 in the practical embodiment, and the limiter 16 is provided on the outer side of the bottom of the upper bin 13. The inner wall of the limiter 16 is adapted to the shape of the outer surface of the lower bin 11. Before fixing the upper bin 13 and the lower bin 11, the position of the lower bin 11 is manually adjusted so that the inner wall of the limiter 16 fits the outer surface of the top of the lower bin 11, thereby realizing the alignment of the lower bin 11 with the upper bin 13, avoiding the problem that the particles to be dried are placed on the connection between the upper bin 13 and the lower bin 11 during the boiling drying process, resulting in ineffective drying.

[0058] In the above structure, the air in the drying chamber 1 can be directly discharged through the air outlet 14. Furthermore, as one of the preferred implementations, the drying chamber 1 in the embodiment of the utility model also includes an exhaust pipe 5, which is arranged on the outside of the loading bin 13. The exhaust pipe 5 is connected to the air outlet 14 for discharging hot air.

[0059] Furthermore, in order to fully utilize the hot air, the outlet of the exhaust pipe 5 is connected to the hot air supply mechanism 4 and heated to a required temperature for reuse.

[0060] Furthermore, as one of the implementation modes, the drying chamber 1 in the embodiment of the utility model further includes a handle 6, and the handle 6 is arranged on the outside of the lower material bin 11. The operator can adjust the position of the lower material bin 11 through the handle 6, which is more convenient.

[0061] Furthermore, as one of the implementation modes, the cross-sectional size of the lower bin 11 in the embodiment of the utility model is gradually reduced. Specifically, from the upper bin 13 to the bottom net 12, the cross-sectional area of ​​the lower bin 11 gradually reduces, and the material output from the conveying slide rail 3 can be concentrated on the bottom net 12 and blown up repeatedly.

[0062] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
