Description

Technical Field

[0001] This invention relates to the field of tobacco manufacturing technology, and in particular to an anti-adhesion vibration conveyor. Background Technology

[0002] In tobacco processing, the SIROX expansion unit is a key piece of equipment for stem handling. The SIROX process features a unique combination of high-temperature steam and vibratory conveying, and its vibratory conveyor has long faced a serious problem of material adhesion. This issue is primarily determined by the process characteristics: the expansion unit typically uses steam at 2 Bar pressure, maintaining an operating temperature between 100℃ and 121℃, while the temperature of the vibratory conveyor trough is usually only around 20℃ to 30℃, the ambient temperature. High-temperature stems generally enter the vibratory conveyor at approximately 65℃. When these stems come into contact with the low-temperature trough surface, intense steam condensation occurs. The resulting condensate combines with sugars, pectin, and other components in the tobacco, forming a highly viscous liquid film on the surface of the vibratory conveyor trough and sealing springs. This leads to significant material adhesion, affecting conveying efficiency and increasing cleaning and maintenance costs.

[0003] Existing technologies attempt to improve the situation through methods such as guide plates and anti-stick coatings, but current industry solutions generally have significant limitations, including complex structures or limited effectiveness. For example, while mechanical guide plates can reduce adhesion in some areas, the added guide plates themselves become new adhesion points and cannot fundamentally solve the problem of steam condensation. Another example is the surface treatment technology for vibrating conveyors, which typically uses ceramic coatings or PTFE coatings. However, this design does not fully consider high-temperature and high-humidity process conditions, making it extremely prone to failure under such conditions. Furthermore, existing anti-stick technologies are mostly developed for conveying dry materials, and their wear resistance is insufficient for continuous production, resulting in unsatisfactory practical application results.

[0004] Since conventional solutions are ineffective, the industry currently relies heavily on a reactive approach of periodic manual cleaning, which not only severely impacts production efficiency but also increases labor costs and quality control difficulties. This situation underscores the necessity and urgency of developing new vibratory conveyors to achieve better anti-sticking technology; a novel vibratory conveyor capable of fundamentally solving the problem is urgently needed. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-adhesion vibrating conveyor that eliminates steam condensation, reduces material adhesion, improves the anti-adhesion effect, eliminates the need for downtime cleaning, has high operating efficiency, and low maintenance costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Anti-adhesion vibratory conveyor, including:

[0008] A tank for receiving materials output from the expansion unit, the tank being capable of vibration to convey the materials;

[0009] The cover is fastened to the top of the tank body. The cover has a feed inlet. The material output by the expansion unit falls into the tank body through the feed inlet. The edge of the cover is provided with a sealing element, which is used to seal the inner wall at the interface between the tank body and the cover body.

[0010] A heating unit, wherein the heating module includes a heating element located outside the tank;

[0011] The lifting support unit includes an elastic connector, a height adjustment part, and a column. The column is supported between the trough and the ground. One end of the elastic connector is connected to the trough, and the height adjustment part is placed between the other end of the elastic connector and the column.

[0012] As an optional technical solution for the anti-adhesion vibration conveyor, multiple elastic connectors are provided, and the multiple elastic connectors are spaced apart.

[0013] As an optional technical solution for the anti-adhesion vibration conveyor, multiple elastic connectors are fixedly connected to the upper surface of the same height adjustment part, which includes multiple height adjustment plates stacked in the vertical direction.

[0014] As an optional technical solution for the anti-adhesion vibration conveyor, multiple height adjustment units are provided, and each height adjustment unit is connected to the elastic connecting member in a one-to-one correspondence. The height adjustment unit includes multiple height adjustment plates stacked in the vertical direction.

[0015] As an optional technical solution for the anti-adhesion vibration conveyor, the distance between the inner wall of the cover and the inner wall of the trough in the vertical direction is 25 mm.

[0016] As an optional technical solution for the anti-adhesion vibration conveyor, the lifting support unit also includes a safety limit block. One end of the safety limit block is fixedly connected to the height adjustment part, and the other end of the safety limit block is movably engaged with the trough in the vertical direction.

[0017] As an optional technical solution for the anti-adhesion vibration conveyor, the heating module also includes a temperature control unit and a power supply. The power supply is used to provide power to the heating element to increase its temperature. The temperature control unit is communicatively connected to the power supply and is used to regulate the temperature of the heating element.

[0018] As an optional technical solution for the anti-adhesion vibratory conveyor, the anti-adhesion vibratory conveyor also includes a temperature sensor, which is used to detect the temperature inside the tank and is communicatively connected to the temperature control unit.

[0019] As an optional technical solution for the anti-adhesion vibration conveyor, the heating module also includes fixing bolts and mounting strips. The heating element is sandwiched between the mounting strips and the trough, and the fixing bolts can pass through the mounting strips and be threadedly connected to the trough.

[0020] As an optional technical solution for the anti-adhesion vibration conveyor, the heating module also includes a protective plate, which is connected to the trough and covers the outside of the heating body.

[0021] The beneficial effects of this invention are:

[0022] The anti-adhesion vibration conveyor provided by this invention includes a trough, a cover, a heating unit, and a lifting support unit. The cover is fastened to the top of the trough and has an inlet. Material output from the expansion unit falls into the trough through the inlet. The trough is used to receive the material output after being processed in the high-temperature steam environment of the expansion unit. The anti-adhesion vibration conveyor can control the vibration of the trough to transport the material. A sealing element is provided on the edge of the cover to seal the inner wall at the interface between the trough and the cover, preventing material leakage or external influence. The lifting support unit includes an elastic connector, a height adjustment part, and a column. The column is supported between the trough and the ground. One end of the elastic connector is connected to the trough, and the other end of the elastic connector is spaced between the elastic connector and the column with the height adjustment part, which can reduce the distance between the cover and the trough and significantly reduce the adhesion points of the material in the trough. At the same time, lowering the position of the sealing element can reduce the adhesion of the material to the sealing element. This structural improvement enhances the anti-adhesion effect. The heating module includes a heating element connected to the outside of the tank. The heating element heats the material and conducts heat to the tank, increasing its temperature and preventing intense steam condensation from the hot material. It also evaporates steam escaping from the material output from the expansion unit. Material adhering to the sides of the tank can also be gradually reduced using the heating element. This anti-adhesion vibrating conveyor uses a non-contact method, eliminating the need for downtime cleaning, significantly improving operating efficiency and greatly reducing maintenance costs. It fundamentally eliminates steam condensation, completely solving the material adhesion problem. Furthermore, it features low energy consumption, a simple and highly integrated structure, avoids additional structures that increase adhesion points, ensures stable and reliable operation, facilitates maintenance, and has a long service life.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0028] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0031] like Figure 1 and Figure 2 As shown, this invention discloses an anti-adhesion vibratory conveyor, including a trough 100, a cover, a heating unit, and a lifting support unit 200. The cover is fastened to the top of the trough 100 and has an inlet. Material output from the expansion unit falls into the trough 100 through the inlet. The trough 100 is used to receive the material output after being treated in a high-temperature steam environment by the expansion unit. The anti-adhesion vibratory conveyor can control the vibration of the trough 100 to transport the material. A sealing element is provided on the edge of the cover to seal the inner wall at the interface between the trough 100 and the cover, preventing material leakage. Leakage or external influences; the lifting support unit 200 includes an elastic connector 210, a height adjustment part 220, and a column 230. The column 230 is supported between the tank 100 and the ground. One end of the elastic connector 210 is connected to the tank 100, and the height adjustment part 220 is placed between the other end of the elastic connector 210 and the column 230. This can reduce the distance between the cover and the tank 100 and significantly reduce the adhesion points of materials in the tank 100. At the same time, lowering the position of the seal can reduce the adhesion of materials to the seal. This structural improvement enhances the anti-adhesion effect.

[0032] The heating module includes a heating element connected to the outside of the tank 100. The heating element heats the tank 100 and conducts heat to it, providing heat and raising its temperature. This prevents the high-temperature material from contacting the tank 100 and causing severe steam condensation. It also evaporates steam escaping from the material output from the expansion unit. Material adhering to the side of the tank 100 can also have its adhesion gradually reduced using the heating element. This anti-adhesion vibrating conveyor uses a non-contact processing method, eliminating the need for downtime cleaning, significantly improving operating efficiency and greatly reducing maintenance costs. It fundamentally eliminates steam condensation, completely solving the material adhesion problem. Furthermore, it has low energy consumption, a simple structure, high integration, avoids additional structures that increase adhesion points, ensures stable and reliable operation, is easy to maintain, and has a long service life. Most importantly, this anti-adhesion vibrating conveyor can be adapted for the retrofitting and upgrading of existing SIROX expansion unit equipment at a low cost.

[0033] In this embodiment, the lifting support unit 200 also includes a ground-connected enlarged surface 250, which is connected to the column 230 and serves as the "foot" of the lifting support unit 200. It is fixed to the ground using four M12 chemical expansion anchors and two M16 double-cone expansion bolts to improve the support stability of the lifting support unit 200 on the tank 100.

[0034] Specifically, multiple elastic connectors 210 are provided. The multiple elastic connectors 210 are of the same specification and are spaced apart, which improves the stability of the connection of the trough 100 and makes the relative position of the connection between the trough 100 and the lifting support unit 200 more balanced and reliable.

[0035] Furthermore, multiple elastic connectors 210 are fixedly connected to the upper surface of the same height adjustment part 220, and the elastic connectors 210 are raised as a whole in one go. The steps are simple and ensure that the lifting support unit 200 has good consistency.

[0036] Optionally, the height adjustment unit 220 includes a plurality of height adjustment plates 221 stacked in the vertical direction. The number of height adjustment plates 221 can be selected, and the thickness of a single height adjustment plate 221 can be changed or replaced to fully set the most suitable lifting height.

[0037] In this embodiment, multiple height adjustment units 220 are provided, and each height adjustment unit 220 is connected to an elastic connector 210 in a one-to-one correspondence. The elastic connectors 210 are raised one by one, which is simple to construct, convenient for individual adjustment or replacement, and provides greater safety assurance.

[0038] Specifically, in terms of structural optimization, the lifting support unit 200 reduces the distance between the cover and the trough 100 by lifting the elastic connectors 210 one by one, reducing the distance from the original 70 mm to a range of 25 mm to 40 mm. For example, the distance between the inner walls of the cover and the trough 100 in the vertical direction is 25 mm. This improvement not only significantly reduces the contact area between the material and the anti-adhesion vibrating conveyor but also facilitates the coverage of the heating unit, further enhancing the anti-adhesion effect.

[0039] It is understood that the lifting support unit 200 also includes a safety limit block 240. One end of the safety limit block 240 is fixedly connected to the height adjustment part 220, and the other end of the safety limit block 240 is movably engaged with the trough 100 in the vertical direction. During the process of the anti-adhesion vibration conveyor controlling the vibration of the trough 100 to transport materials, the elastic connector 210 will give the trough 100 a certain degree of vibration freedom. The safety limit block 240 limits the movement between the lifting support unit 200 and the trough 100, preventing the elastic connector 210 from breaking under fatigue working conditions or other unexpected situations that would cause the lifting support unit 200 to lose control of the trough 100, thus improving the safety of the anti-adhesion vibration conveyor.

[0040] Furthermore, the heating module also includes a temperature control unit and a power supply. The power supply provides electricity to the heating element to increase its temperature. The temperature control unit communicates with the power supply and is controlled by a PLC (Programmable Logic Controller) to adjust the heating temperature of the heating element, allowing for temperature changes as needed. The adjustable temperature range is 0–400℃. When the temperature of the tank 100 becomes too high, the temperature control unit automatically lowers the heating element temperature to prevent further moisture loss and maintain normal material humidity.

[0041] Specifically, the anti-adhesion vibration conveyor also includes a temperature sensor, which is used to detect the temperature inside the tank 100. The temperature sensor is connected to the temperature control unit to realize real-time temperature monitoring and closed-loop control, ensuring temperature stability throughout the entire working process.

[0042] The specific working process of the anti-adhesion vibration conveyor is as follows: First, the tank 100 is preheated. The temperature control unit of the PLC control system achieves precise temperature regulation. When the temperature control unit receives the preheating signal, it heats the heating element. The temperature is raised to 140℃ and maintained for 10 minutes to ensure that the tank 100 of the anti-adhesion vibration conveyor is fully dry. Then, it is determined whether the preheating conditions have been met. If so, feeding is allowed. During the operation phase, the temperature control unit controls the reduction of the heating element temperature. During normal production, the temperature is stably maintained at around 80℃, always higher than the condensation point of the material. Finally, during the shutdown phase, it is checked whether production is completed. After production is completed, the anti-adhesion vibration conveyor stops, steam heating is no longer supplied to the heating element, and the power is automatically cut off to ensure equipment safety.

[0043] For example, the heating module also includes fixing bolts and mounting strips. The heating element is sandwiched between the mounting strips and the trough 100. The fixing bolts can pass through the mounting strips and be threadedly connected to the trough 100, which facilitates the disassembly or replacement of the heating element by the anti-adhesion vibration conveyor.

[0044] Optionally, in terms of safety protection, the heating module is also equipped with a dedicated protective plate. The protective plate is connected to the tank 100 and is placed on the outside of the heating body. It can be used as a design to prevent burns and improve the safety of staff maintaining and observing the anti-adhesion vibrating conveyor. It can also effectively prevent the heating body from being damaged by bumps, thereby avoiding safety hazards.

[0045] This anti-adhesion vibrating conveyor has significant practical implications for optimizing and improving the tobacco processing technology. It not only solves the technical challenges currently facing the tobacco industry, but also provides a new approach and solution for conveying highly adhesive materials such as food under similar working conditions.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
