Description

Technical Field

[0001] This utility model relates to the field of conveyor belt technology, specifically a mesh belt for a pyrolysis furnace. Background Technology

[0002] Pyrolysis furnaces, as important thermochemical processing equipment, are widely used in fields such as solid waste resource utilization, biomass energy production, and chemical raw material production. In continuous pyrolysis processes, the mesh belt, as the core load-bearing and conveying component, directly determines the residence time of materials in the furnace, the uniformity of heating, and the overall processing efficiency and stability of the system.

[0003] The existing mesh belt system suffers from insufficient tension control precision, making it difficult to adapt to dynamically changing operating conditions. During pyrolysis, the mesh belt needs to carry a large amount of material and withstand the thermal expansion effect caused by the high temperature inside the furnace. Traditional tensioning devices mostly use fixed weights or screws for simple adjustment, with a fixed tension or only allowing for rough adjustments when the machine is stopped. When the material distribution is uneven or the load at a single point is too heavy, the mesh belt is prone to local sagging and deviation, causing it to undulate in the high-temperature section. This unevenness results in uneven material thickness and differences in the heated area, ultimately leading to incomplete pyrolysis and large fluctuations in product quality. At the same time, the sagging of the mesh belt will increase friction with the furnace sidewalls or supports, significantly shortening its service life.

[0004] Secondly, the issue of cleaning the conveyor belt surface has long plagued continuous production. During material transport or low-temperature pyrolysis, some incompletely melted or reacted semi-fluid substances easily adhere to and accumulate on the conveyor belt surface. This continuous accumulation of deposits severely hinders the penetration of hot air through the material layer, affecting heat transfer efficiency and altering the weight distribution and stress balance of the conveyor belt, exacerbating the aforementioned sagging and misalignment problems. Frequent downtime for manual cleaning directly leads to production interruptions, reduces equipment utilization, and poses safety hazards during cleaning operations in high-temperature environments.

[0005] Therefore, there is an urgent need in this field for a new type of mesh belt system for pyrolysis furnaces that can dynamically adjust the mesh belt tension to ensure that the mesh belt can maintain flatness and stable operation under various loads. Summary of the Invention

[0006] The purpose of this invention is to provide a mesh belt for a pyrolysis furnace to solve the problems mentioned in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: the mesh belt for the pyrolysis furnace includes a support frame, fixed plates are symmetrically installed on the top of the support frame, a transmission assembly is installed between the two fixed plates, a mesh belt is wound around the transmission assembly, a support rod is installed between the two fixed plates, and adjusting components are installed at both ends of the inner side of the fixed plates.

[0008] As a preferred technical solution, the support frame is provided with several mounting plates on its outer side and an adjustment pad is provided at the bottom of the support frame.

[0009] As a preferred technical solution, the fixing plate is connected to the support frame through the mounting plate, the two fixing plates are mirror images of each other, the fixing plate is provided with a square groove, the fixing plate is provided with a straight groove, the straight groove is located below the square groove, a tension spring is provided in the straight groove, a toggle groove is provided on one side of the straight groove, and an adjustment groove is provided at both ends of the fixing plate.

[0010] As a preferred technical solution, a tensioning member is installed on the outside of the fixing plate. The tensioning member is located below the square groove. A lifting rod is provided inside the tensioning member. A roller is provided on one side of the lifting rod. A cam is provided on one side of the tensioning member. A scraper is installed between the two tensioning members. Connecting posts are provided at both ends of the scraper.

[0011] As a preferred technical solution, the transmission assembly includes an adjusting shaft disposed at the ends of the two fixed plates, a transmission shaft disposed below the adjusting shaft, a tensioning shaft disposed inside the transmission shaft, and square blocks disposed at both ends of the tensioning shaft.

[0012] As a preferred technical solution, the mesh belt is provided with a plurality of mesh holes evenly distributed on it.

[0013] As a preferred technical solution, a vision sensor is provided at the bottom of the support rod, and a positioning rod is provided at the top of the support rod.

[0014] As a preferred technical solution, the adjusting component includes a servo motor, the output end of which is connected to a push rod, and a connecting ring is provided at the end of the push rod, which is sleeved on the adjusting shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. During the mesh belt drive process, the visual sensor installed at the bottom of the support rod can monitor the flatness of the mesh belt at all times. Then, through the drive of the tensioning and adjusting components, the tensioning shaft and adjusting shaft can be moved, thereby changing the tension of the mesh belt and straightening the uneven mesh belt. In addition, support rods are installed at both ends of the fixed plate, which can verify the adjustment of the mesh belt tension. 2. When waste photovoltaic panels are transported to the pyrolysis furnace for decomposition via a mesh belt, some incompletely pyrolyzed substances will adhere to the mesh belt. By setting up a scraper, these attached impurities can be scraped off to avoid affecting subsequent transportation and the pyrolysis process. 3. To ensure the scraping efficiency of the scraper, the scraper will contact a section of the inclined mesh belt. When the tension of the mesh belt is adjusted, the angle of the inclined section will change, which will cause the pressure of the scraper on the mesh belt to increase. By setting a cam and a tension spring, the distance between the scraper and the mesh belt can be adjusted, thereby preventing the scraper from damaging the mesh belt. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figures 1-4As shown, this utility model provides a technical solution for a mesh belt for a pyrolysis furnace. The mesh belt for the pyrolysis furnace includes a support frame 1, with fixed plates 2 symmetrically installed on the top of the support frame 1. A transmission assembly 3 is installed between the two fixed plates 2, and a mesh belt 4 is wound around the outside of the transmission assembly 3. A support rod 5 is installed between the two fixed plates 2, and an adjusting member 6 is installed at both ends of the inner side of the fixed plate 2. The mesh belt 4 is installed between the two fixed plates 2 through the transmission assembly 3, and the limiting effect of the transmission assembly 3 ensures that the mesh belt 4 wound around the outside of the transmission assembly 3 can just coincide with the edge of the fixed plate 2. In the transmission assembly 3, the two ends of the adjusting shaft 31 are embedded in the adjusting grooves 24 of the two fixed plates 2. At the same time, the two ends of the adjusting shaft 31 are fixed by the adjusting member 6 through the sleeved connecting rings 63. The adjusting shaft 31 is located at the upper end of the fixed plate 2, and the transmission shaft 32 is located at the lower end of the fixed plate 2. The square blocks 3301 at both ends of the tensioning shaft 33 are embedded in the square grooves 21, which can ensure that the tensioning shaft 33 can move up and down along the square grooves 21.

[0020] When the conveyor belt 4 transports waste photovoltaic panels into the pyrolysis furnace, the weight of the panels may cause parts of the belt 4 to sink, leading to friction between the sunken portion and furnace components, thus affecting the overall lifespan of the belt 4. Therefore, the visual sensor 51 at the bottom of the support rod 5 can monitor the sinking of the belt 4 in real time. The servo motor 61 then drives the push rod 62 to push the adjusting shafts 31 at both ends outwards, pulling the belt 4 to some extent and repairing the sunken areas. Simultaneously, the rollers 2502 inside the tensioning member 25 can raise the lifting rod 2501, causing the tensioning shaft 33 to rise, further pulling the belt 4 and ensuring its flatness. During the pyrolysis of the waste photovoltaic panels, some incompletely decomposed material may adhere to the belt 4. This material can be completely removed by the scraper 26. To ensure the cleaning efficiency of the scraper 26, it is placed horizontally and in contact with an inclined section of the belt 4. Since the tension of the conveyor belt 4 needs frequent adjustment, the degree of inclination of this inclined section of the conveyor belt 4 will change due to the change in tension. This will increase the pressure of the inclined section of the conveyor belt 4 on the scraper 26, which may cause damage to the conveyor belt 4 during the cleaning process. To avoid this, the connecting posts 2601 at both ends of the scraper 26 are embedded in the straight groove 22. The tension spring 2201 in the straight groove 22 will abut against the connecting posts 2601. When the tension of the conveyor belt 4 changes, the tensioning element will... 25 drives the cam 2503 on one side of the straight groove 22 to rotate. When the cam 2503 rotates, it pushes the connecting column 2601 towards the other end of the straight groove 22 and compresses the tension spring 2201. The movement of the connecting column 2601 will drive the entire scraper 26 to move, thereby changing the distance between the scraper 26 and the mesh belt 4 to prevent the scraper 26 from damaging the mesh belt 4. After the tension of the mesh belt 4 is adjusted, the cam 2503 rotates to its original position. Under the restoring force of the tension spring 2201, the scraper 26 will also return to its original position.

[0021] Several mounting plates 11 are provided on the outside of the support frame 1, and an adjustment pad 12 is provided at the bottom of the support frame 1. The adjustment pad 12 can reduce the vibration of the entire device and prevent the waste photovoltaic panels from being shaken off during the conveying process of the mesh belt 4.

[0022] The fixing plate 2 is connected to the support frame 1 via the mounting plate 11. The two fixing plates 2 are mirror images of each other. The fixing plate 2 has a square groove 21 and a straight groove 22. The straight groove 22 is located below the square groove 21. A tension spring 2201 is installed in the straight groove 22. A toggle groove 23 is provided on one side of the straight groove 22. Adjustment grooves 24 are provided at both ends of the fixing plate 2.

[0023] Tensioning member 25 is installed on the outside of fixed plate 2. Tensioning member 25 is located below square groove 21. Lifting rod 2501 is provided inside tensioning member 25. Roller 2502 is provided on one side of lifting rod 2501. Cam 2503 is provided on one side of tensioning member 25. Scraper 26 is installed between two tensioning members 25. Connecting post 2601 is provided at both ends of scraper 26.

[0024] The transmission assembly 3 includes an adjusting shaft 31 disposed at the ends of the two fixed plates 2, a transmission shaft 32 disposed below the adjusting shaft 31, a tensioning shaft 33 disposed inside the transmission shaft 32, and square blocks 3301 disposed at both ends of the tensioning shaft 33. In the transmission assembly 3, the two ends of the adjusting shaft 31 are embedded in the adjusting grooves 24 of the two fixed plates 2, and the two ends of the adjusting shaft 31 are fixed by the adjusting member 6 through the sleeved connecting rings 63. The adjusting shaft 31 is located at the upper end of the fixed plate 2, and the transmission shaft 32 is located at the lower end of the fixed plate 2. The square blocks 3301 at both ends of the tensioning shaft 33 are embedded in the square grooves 21, which can ensure that the tensioning shaft 33 moves up and down along the square grooves 21.

[0025] A vision sensor 51 is installed at the bottom of the support rod 5, and a positioning rod 52 is installed at the top of the support rod 5. The adjusting component 6 includes a servo motor 61, the output end of which is connected to the push rod 62. A connecting ring 63 is installed at the end of the push rod 62, and the connecting ring 63 is sleeved on the adjusting shaft 31. The vision sensor 51 at the bottom of the support rod 5 can monitor the sinking of the mesh belt 4 in real time, and then drive the servo motor 61. The servo motor 61 causes the push rod 62 to push the adjusting shafts 31 at both ends outward. By pulling the mesh belt 4, the sinking part can be repaired to a certain extent. At the same time, the roller 2502 in the tensioning component 25 can drive the lifting rod 2501 to rise. The rise of the lifting rod 2501 raises the position of the tensioning shaft 33, further pulling the mesh belt 4 to ensure the flatness of the mesh belt 4.

[0026] The working principle of this utility model: The mesh belt 4 is installed between the two fixed plates 2 through the transmission assembly 3, and the limiting effect of the transmission assembly 3 ensures that the mesh belt 4 wrapped around the outside of the transmission assembly 3 can just coincide with the edge of the fixed plate 2.

[0027] In the transmission assembly 3, the two ends of the adjusting shaft 31 are embedded in the adjusting grooves 24 of the two side fixing plates 2. At the same time, the two ends of the adjusting shaft 31 are fixed by the adjusting component 6 through the sleeved connecting rings 63. The adjusting shaft 31 is located at the upper end of the fixing plate 2, while the transmission shaft 32 is located at the lower end of the fixing plate 2. The square blocks 3301 at both ends of the tensioning shaft 33 are embedded in the square grooves 21, which can ensure that the tensioning shaft 33 moves up and down along the square grooves 21.

[0028] When the conveyor belt 4 transports waste photovoltaic panels into the pyrolysis furnace, the weight of the waste photovoltaic panels may cause parts of the conveyor belt 4 to sink, which in turn causes the sunken parts to rub against the components of the pyrolysis furnace, affecting the overall service life of the conveyor belt 4. Therefore, the visual sensor 51 at the bottom of the support rod 5 can monitor the sinking of the conveyor belt 4 in real time, and then drive the servo motor 61. The servo motor 61 drives the push rod 62 to push the adjusting shafts 31 at both ends outward. By pulling the conveyor belt 4, the sunken parts can be repaired to a certain extent. At the same time, the roller 2502 in the tensioning member 25 can drive the lifting rod 2501 to rise. The rise of the lifting rod 2501 raises the position of the tensioning shaft 33, further pulling the conveyor belt 4 to ensure the flatness of the conveyor belt 4.

[0029] During the pyrolysis of waste photovoltaic panels, some incompletely decomposed materials may adhere to the mesh belt 4. These materials can be completely removed by the scraper 26. To ensure the cleaning efficiency of the scraper 26, it is placed horizontally and in contact with an inclined section of the mesh belt 4. Since the tension of the mesh belt 4 is frequently adjusted, the inclination of this inclined section changes due to tension variations, leading to increased pressure on the scraper 26. This could potentially damage the mesh belt 4 during the cleaning process. To avoid this, the connecting posts 2601 at both ends of the scraper 26 are embedded in the straight grooves 22. The tension spring 2201 inside the straight groove 22 will abut against the connecting post 2601. When the tension of the mesh belt 4 changes, the tensioning member 25 drives the cam 2503 on one side of the straight groove 22 to rotate. When the cam 2503 rotates, it will push the connecting post 2601 to the other end of the straight groove 22 and compress the tension spring 2201 at the same time. The movement of the connecting post 2601 will drive the entire scraper 26 to move, thereby changing the distance between the scraper 26 and the mesh belt 4, so as to avoid the scraper 26 damaging the mesh belt 4. After the tension of the mesh belt 4 is adjusted, the cam 2503 rotates to its original position. Under the restoring force of the tension spring 2201, the scraper 26 will also return to its original position.

[0030] During the transmission of the mesh belt 4, the flatness of the mesh belt 4 can be monitored at all times by the vision sensor 51 set at the bottom of the support rod 5. Then, through the drive of the tensioning member 25 and the adjusting member 6, the tensioning shaft 33 and the adjusting shaft 31 can be moved, thereby changing the tension of the mesh belt 4 and straightening the uneven mesh belt 4. In addition, the support rods 5 are installed at both ends of the fixing plate 2, which can verify the adjustment of the tension of the mesh belt 4.

[0031] When waste photovoltaic panels are transported to the pyrolysis furnace for decomposition via the mesh belt 4, some incompletely pyrolyzed substances will adhere to the mesh belt 4. By setting up the scraper 26, these attached impurities can be scraped off to avoid affecting subsequent transportation and the pyrolysis process.

[0032] To ensure the scraping efficiency of the scraper 26, the scraper 26 will contact a section of the inclined mesh belt 4. When the tension of the mesh belt 4 is adjusted, the angle of the inclined section will change, which will cause the pressure of the scraper 26 on the mesh belt 4 to increase. By setting the cam 2503 and the tension spring 2201, the distance between the scraper 26 and the mesh belt 4 can be adjusted, thereby preventing the scraper 26 from damaging the mesh belt 4.
