Benefits of technology

[0015] As described above, the material transfer mechanism of the present invention has the following beneficial effects: By setting a pushing member and an overall displacement assembly, when the material is on the movement trajectory of the pushing member, the overall displacement assembly can drive the pushing assembly to move along a first direction and push the material forward in the first direction. When the pushing member is in the raised position, the material is outside the movement trajectory of the pushing member, and the overall displacement assembly drives the pushing assembly to move in the opposite direction of the first direction, returning to the position before pushing. Since the material is outside the movement trajectory of the pushing member, the overall displacement assembly will not push the material backward in the first direction when it moves in the opposite direction. The overall displacement assembly and the pushing member work together in this way to achieve long-distance material movement over a long period of time through short-distance stepping, thus completing the pushing and transfer of materials. Because the material transfer mechanism uses a reciprocating material movement and conveying method, its structure is simple and can adapt to the high-temperature environment in the anaerobic pyrolysis furnace, avoiding thermal deformation and jamming of the material transfer mechanism in the anaerobic pyrolysis furnace. The material transfer mechanism transports materials continuously and stably.

Description

Technical Field

[0001] This invention relates to the field of pyrolysis, and in particular to a material transport mechanism. Background Technology

[0002] In industrial production, materials are frequently moved, and this movement directly impacts production efficiency. In certain special environments, such as high-temperature environments, most material handling mechanisms are prone to heat-induced deformation and jamming of components during long-distance transport. Therefore, high-temperature environments place higher demands on material handling mechanisms.

[0003] Currently, both dryers and pyrolysis furnaces operate in high-temperature environments, requiring material transport mechanisms to move materials. Taking a continuous anaerobic pyrolysis furnace as an example, it requires continuous feeding, discharging, and movement of the material to be pyrolyzed to ensure the stability of the pyrolysis process. The furnace contains flammable and explosive pyrolysis gas under slight positive pressure. Continuous feeding and movement of the material are essential to maintain relatively stable pyrolysis gas pressure. If pressure fluctuations cause the furnace pressure to exceed the process value, pyrolysis gas will overflow and pollute the environment. Conversely, if pressure fluctuations cause the furnace pressure to fall below the process value, negative pressure will be created, drawing in air. If the air content reaches the explosion point and encounters an open flame, a combustion explosion is highly likely, potentially leading to a serious safety accident. Therefore, a material transport mechanism capable of continuously and stably conveying materials is crucial for anaerobic pyrolysis furnaces. Furthermore, anaerobic pyrolysis furnaces require excellent sealing. Because the temperature inside an anaerobic pyrolysis furnace is high to meet pyrolysis requirements, the mechanisms used for material transport within it must withstand these high temperatures. However, in high-temperature environments, most commercially available material transport mechanisms are prone to thermal deformation and jamming, making it difficult to guarantee the smooth operation of material transport within the anaerobic pyrolysis furnace. Summary of the Invention

[0009] Optionally, the material transport mechanism includes a lifting assembly, which is mounted on an oxygen-free pyrolysis furnace. The lifting assembly is used to lift the overall displacement assembly. The lifting assembly includes a first roller and a second roller that cooperates with the first roller.

The first roller is used to lift the overall displacement assembly, and the second roller is used to cooperate with the first roller to limit the sliding bar.

[0010] Optionally, along the first direction, the first roller and the second roller are symmetrically arranged on both sides of the sliding bar.

[0011] Optionally, the pushing assembly includes a plurality of pushing members, which are arranged sequentially along the first direction.

[0012] Optionally, the pusher has an insertion portion, and the rotating rod is provided with an insertion hole corresponding to the insertion portion. The insertion portion passes through the insertion hole, and the pusher can move along the axial direction of the insertion hole. A limit block is provided at one end of the insertion portion that passes through the insertion hole, and the limit block is used to limit the insertion portion.

[0013] Optionally, the transmission assembly includes a third roller and a fourth roller, both of which are mounted on the overall displacement assembly. The third roller is used to support the actuating lever, and the fourth roller is used to cooperate with the third roller to clamp the actuating lever.

[0014] Optionally, the overall displacement assembly includes a displacement rod, the transmission assembly includes a toggle rod, the pushing member is disposed on the displacement rod, the toggle rod is movably disposed on the displacement rod along the first direction, the displacement rod is used to drive the pushing member and the toggle rod to move, the toggle rod is used to drive the pushing member to switch between the pushing position and the lifting position, the material transfer mechanism is at least partially disposed inside the transfer box, the displacement rod and the toggle rod pass through the outside of the transfer box into the inside of the transfer box, and sealing assemblies are provided on the outer wall of the transfer box through which the displacement rod and the toggle rod pass, the sealing assemblies being used to seal the gap between the displacement rod or the toggle rod and the transfer box.

[0015] As described above, the material transfer mechanism of the present invention has the following beneficial effects: By setting a pushing member and an overall displacement assembly, when the material is on the movement trajectory of the pushing member, the overall displacement assembly can drive the pushing assembly to move along a first direction and push the material forward in the first direction. When the pushing member is in the raised position, the material is outside the movement trajectory of the pushing member, and the overall displacement assembly drives the pushing assembly to move in the opposite direction of the first direction, returning to the position before pushing. Since the material is outside the movement trajectory of the pushing member, the overall displacement assembly will not push the material backward in the first direction when it moves in the opposite direction. The overall displacement assembly and the pushing member work together in this way to achieve long-distance material movement over a long period of time through short-distance stepping, thus completing the pushing and transfer of materials. Because the material transfer mechanism uses a reciprocating material movement and conveying method, its structure is simple and can adapt to the high-temperature environment in the anaerobic pyrolysis furnace, avoiding thermal deformation and jamming of the material transfer mechanism in the anaerobic pyrolysis furnace. The material transfer mechanism transports materials continuously and stably. Attached Figure Description

The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0029] Please see Figures 1 to 11It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show components relevant to the present invention and are not drawn according to the actual number, shape, and size of components in implementation.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effects and objectives of the present invention, should still fall within the scope of the technical content disclosed in the present invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are only for clarity of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the present invention.

[0030] Before describing the embodiments of the present invention in detail, the application background of the present invention will be described first. In industrial environments, material transfer mechanisms are often used in high-temperature environments, such as drying and pyrolysis. Here, a continuous anaerobic pyrolysis furnace is used as an example for specific description. The continuous anaerobic pyrolysis furnace requires that the material 14 to be pyrolyzed be continuously fed in and out and continuously moved to ensure the stability of the pyrolysis process. The furnace interior of the continuous anaerobic pyrolysis furnace contains flammable and explosive pyrolysis gas and is under slight positive pressure. Only when the material 14 is continuously fed in and out and continuously moved can the pressure of the pyrolysis gas inside the furnace be kept relatively stable. When the pressure inside the furnace fluctuates and causes the pressure to exceed the process value, the pyrolysis gas will overflow and pollute the environment. When the pressure inside the furnace fluctuates and causes the pressure to fall below the process value, negative pressure occurs, which easily draws in air. Once the air content inside the furnace reaches the explosion point and comes into contact with an open flame, it is very easy to cause combustion and explosion, or even serious safety accidents. Therefore, it is crucial to have a device that can continuously and stably move the material 14 in the anaerobic pyrolysis furnace, especially for anaerobic pyrolysis furnaces with high heat exchange efficiency. The temperature inside a continuous anaerobic pyrolysis furnace is 400-600 degrees Celsius. In a typical material movement mechanism, the mechanical structure may become jammed due to thermal deformation under high temperatures, causing the equipment to malfunction. Because the anaerobic pyrolysis furnace is a high-temperature environment, the material movement mechanism inside will deform due to the high temperature. Ensuring the normal movement of material 14 despite high-temperature deformation is a basic requirement for the material movement mechanism.

[0031] Meanwhile, continuous anaerobic pyrolysis furnaces have high requirements for sealing, and the furnace must maintain an oxygen-free environment. Conventional material conveying mechanisms struggle to simultaneously ensure continuous movement of material 14 within the furnace and maintain airtightness at the material 14 inlet / outlet and all connections to the outside. High-temperature sealing of anaerobic pyrolysis furnaces is also a significant challenge. Typically, solid waste and hazardous waste materials 14 are in strip or block shape, with some materials being granular or powdery. Strip and block shapes are highly prone to jamming the material 14 pushing mechanism. Improving the anaerobic pyrolysis furnace's capacity to accommodate material 14 and preventing jamming is a major challenge for the material conveying mechanism. The pyrolysis time of material 14 is generally longer than incineration time; for example, the pyrolysis time for waste salt requires 4-6 hours. In high-temperature environments, long-distance, multi-stroke movement of material 14 relies on the material conveying mechanism. Currently, most material 14 pushing technologies are not suitable for high-temperature, long-distance conveying.

[0032] During the pyrolysis process in a continuous anaerobic pyrolysis furnace, some of the material 14 will carbonize inside the furnace wall. An automatic carbonization cleaning mechanism is needed to prevent the moving mechanism from being jammed by carbon buildup. Furthermore, carbonization reduces the heating efficiency of the anaerobic pyrolysis furnace. The key technology for a high-efficiency continuous anaerobic pyrolysis furnace is to develop a material 14 moving device that can achieve continuous and stable movement of the material 14 under high-temperature conditions, preventing mechanical jamming due to high temperatures and ensuring the moving mechanism is not blocked by the material 14. Simultaneously, it must maintain good sealing of the anaerobic pyrolysis furnace to prevent pyrolysis gas leakage or air intrusion. This device must also have the function of automatically cleaning carbon buildup from the furnace wall.

[0033] Currently, rotary kiln anaerobic pyrolysis furnaces have relatively mature technology in the pyrolysis field, hence their largest market share. In a rotary kiln anaerobic pyrolysis furnace, the material 14 is moved by the rotation of the furnace cylinder, which has an inclined angle. The material 14 is propelled by the cylinder, climbing up the inner circumferential wall of the cylinder and falling after reaching a certain height. Due to the inclined angle of the cylinder, the material 14 falls forward to the bottom, thus achieving continuous movement. This movement method of the material 14 is ideal, preventing mechanical jamming due to high temperatures, and it has excellent material containment capabilities. This is why the rotary kiln anaerobic pyrolysis furnace remains the mainstream type of anaerobic pyrolysis furnace. However, rotary kiln anaerobic pyrolysis furnaces also have disadvantages. Because the heat exchange cylinder is constantly rotating, the position of the material 14 within the cylinder is constantly changing, resulting in very low heat exchange efficiency. Furthermore, to ensure cylinder strength, the filling rate is very low, leading to a large equipment size and high cost. Furthermore, rotary kiln-type anaerobic pyrolysis furnaces have large cylinder diameters, typically between 1.5 and 3 meters. High-temperature sealing is very difficult at such a large size, and achieving a satisfactory seal requires specialized and complex sealing devices, resulting in high costs. The ideal is to invent a new furnace type that possesses both strong material containment capacity and high heat exchange efficiency, while also being compact and inexpensive, to replace the rotary kiln-type anaerobic pyrolysis furnace. However, achieving both is extremely difficult. The key technology, namely, fully functional material movement technology, has not yet been mastered.

[0034] The spiral anaerobic pyrolysis furnace propels material 14 by a spiral shaft. Because the furnace body is stationary, the heating surface of material 14 remains constant, resulting in high heat exchange efficiency, a very high fill rate, and a small equipment size. Sealing is only required on the spiral shaft, and conventional seals are sufficient, making sealing inexpensive. However, due to the rotating nature of the spiral, it is highly susceptible to high-temperature deformation, which can easily cause the spiral to jam. The spiral itself is also a slender rotating body, and thermal deformation can prevent it from rotating properly. Furthermore, strip-shaped and blocky materials frequently jam the spiral. These fatal flaws limit the spiral anaerobic pyrolysis furnace to its applications, making it suitable only for pyrolysis at relatively low temperatures and for materials 14 that are small particles, powders, or mud. This furnace type is currently on the verge of being phased out.

[0035] Therefore, this application proposes a material transfer mechanism, which is particularly suitable for solving the problem of transferring bulk materials in an anaerobic pyrolysis furnace. It is suitable for materials 14 such as lumps, strips, granules and powders, and has good adaptability to different materials 14. Moreover, the material transfer mechanism is safe, reliable, stable, continuous and environmentally friendly. It is suitable for static anaerobic pyrolysis furnaces with high heat exchange efficiency, realizes the multi-stroke long-term transfer of materials 14, and meets the requirements of high filling rate and small volume of anaerobic pyrolysis furnace.

[0036] Please see Figures 1 to 9 This invention provides a material transport mechanism, including an overall displacement component and a pushing component. The pushing component is connected to the overall displacement component. The overall displacement component is used to drive the pushing component to push the material along a first direction, which is the direction in which the material 14 is transported. The pushing component includes a pushing member 3 for pushing the material 14. The pushing member 3 has a raised position and a pushing position. When the pushing member 3 is in the pushing position, the material 14 is located on the movement trajectory of the pushing member 3. The overall displacement component drives the pushing component to move along the first direction and push the material 14. When the pushing member 3 is in the raised position, the material 14 is outside the movement trajectory of the pushing member 3. The overall displacement component drives the pushing component to move in the opposite direction of the first direction. By configuring the pusher 3 and the overall displacement assembly, when the material 14 is on the movement trajectory of the pusher 3, the overall displacement assembly can drive the pusher assembly to move along the first direction and push the material 14 forward in the first direction. When the pusher 3 is in the raised position, the material 14 is outside the movement trajectory of the pusher 3. The overall displacement assembly drives the pusher assembly to move in the opposite direction of the first direction, returning to the position before pushing. At this time, since the material 14 is outside the movement trajectory of the pusher 3, the overall displacement assembly will not push the material 14 backward in the first direction when it moves in the opposite direction. In this way, the material 14 can be moved over a long period of time and distance through short-distance stepping, transporting the material 14 to the target position. The material transport mechanism can be used for ordinary material transport, and it is also suitable for material transport in high-temperature environments, such as pyrolysis and drying environments, and is especially suitable for oxygen-free pyrolysis furnaces.

[0037] The material transfer mechanism also includes a transmission assembly, which is mounted on the overall displacement assembly. The transmission assembly moves relative to the overall displacement assembly, simultaneously driving the pusher 3 to both the raised and pushed positions. By providing a transmission assembly that can move relative to the overall displacement assembly, the pusher 3 can be moved to either the raised or pushed position when moving relative to the overall displacement assembly, facilitating changes in the position of the pusher 3. When the overall displacement assembly moves along the first direction, the transmission assembly drives the pusher 3 to the pushed position, allowing the pusher 3 to push the material 14. When the overall displacement assembly moves in the opposite direction of the first direction, the transmission assembly drives the pusher 3 to the raised position, preventing the pusher 3 from pushing the material 14 back in the opposite direction of the first direction while moving with the overall displacement assembly.

[0038] Specifically, the overall displacement assembly includes a rotating rod 11, and a pushing member 3 is disposed on the rotating rod 11. The rotating rod 11 drives the pushing member 3 to rotate around the central axis of the rotating rod 11. The rotation of the rotating rod 11 around its own central axis drives the pushing member 3 to move, facilitating the change of the pushing member 3 from a pushing position to a lifting position. The anaerobic pyrolysis furnace has a transport surface for transporting material 14, and the pushing member 3 has a pushing surface for pushing material 14. In this embodiment, when the overall displacement assembly moves along the first direction, the pushing surface of the pushing member 3 is perpendicular to the transport surface, which increases the contact area between the pushing surface and the material 14; when the overall displacement assembly moves in the opposite direction of the first direction, the pushing surface of the pushing member 3 is parallel to the transport surface, making it difficult for the pushing member 3 to contact the material 14, thereby preventing the pushing member 3 from pushing the material 14 during the retraction process. In this embodiment, multiple pushing members 3 are disposed on one rotating rod 11, and the multiple pushing members 3 are arranged sequentially along the axial direction of the rotating rod 11. Multiple pushers 3 are provided on the rotating rod 11 to distribute the force on the pushers 3 when pushing the material 14, and to avoid the situation where the connection between the pushers 3 and the rotating rod 11 is easily damaged due to the excessive force on the pushers 3 when pushing the material 14.

[0039] In detail, the transmission assembly includes a toggle lever 4 arranged along a first direction, a shift fork 12 disposed on a rotating rod 11, and a toggle member 21 corresponding to the shift fork 12. The toggle lever 4 is disposed on the overall displacement assembly, and the toggle member 21 is disposed on the toggle lever 4. The toggle member 21 is used to actuate the corresponding shift fork 12, driving the push member 3 to move to the raised or pushed position. The toggle lever 4 will undergo thermal deformation in a high-temperature environment, which may cause changes in the spacing between adjacent toggle members 21 on the toggle lever 4, resulting in changes in the relative position between the toggle member 21 and the push member 3. At this time, the toggle member 21 may have difficulty driving the push member 3 to move according to the predetermined trajectory. The toggle lever 4 drives the push member 3 to move through the toggle member 21 and the shift fork 12. The open design of the shift fork 12 avoids the toggle lever 4 from becoming stuck due to thermal deformation caused by thermal expansion and contraction of the transmission assembly, thus affecting the normal operation of the transmission assembly. In this embodiment, the actuating member 21 is T-shaped and has two short arms for actuating the shift fork 12. The shift fork 12 has a actuating part that contacts the actuating member 21, and the actuating part has a relief groove for avoiding the actuating member 21. When the two short arms of the actuating member 21 contact the shift fork 12 located on both sides of the relief groove, the actuating member 21 drives the shift fork 12 to move. This arrangement increases the reliability of the actuating member 21 actuating the shift fork 12. Since the actuating member 21 has two short arms for actuating the shift fork 12, it avoids the problem of the actuating member 21 slipping off when actuating the shift fork 12 due to high temperature deformation, which would cause actuation failure.

[0040] Please see Figure 4 , Figure 5 and Figure 8The material transport mechanism includes a lifting assembly mounted on the anaerobic pyrolysis furnace. The lifting assembly supports the overall displacement assembly and includes a first roller 10 and a second roller 5 that cooperates with the first roller 10. The overall displacement assembly includes a sliding strip 7, which is positioned along a first direction on the displacement rod 11 and is held between the first roller 10 and the second roller 5. The first roller 10 supports the overall displacement assembly, and the second roller 5 cooperates with the first roller 10 to limit the sliding strip 7. Through the cooperation of the first roller 10 and the sliding strip 7 in the lifting assembly, the weight of the overall displacement assembly and the transmission assembly can be distributed, preventing the overall displacement assembly from tipping over due to its own weight and load. The second roller 5 cooperates with the first roller 10 to limit the overall displacement assembly, preventing it from tilting to the side. Furthermore, while supporting the overall displacement assembly, the lifting assembly also allows the overall displacement assembly to move within the anaerobic pyrolysis furnace, facilitating the overall displacement assembly to drive the transmission assembly to push the material 14. The structure, achieved through the cooperation of the first roller 10, the second roller 5, and the sliding strip 7, is simple, easy to assemble, and yields good results. It is important to note that a necessary gap must be maintained between the first roller 10, its corresponding second roller 5, and the actuating component 21 to prevent changes in their relative positions under high-temperature conditions, or deformation of the sliding strip 7, which could lead to the sliding strip 7 becoming stuck between the first roller 10 and the second roller 5.

[0041] Please see Figure 2 and Figure 8 In this embodiment, along the first direction, a first roller 10 and a second roller 5 are symmetrically arranged on both sides of the sliding bar 7. By providing a first roller 10 and a second roller 5 on both sides of the sliding bar 7, the first roller 10 and the second roller 5 on both sides of the sliding bar 7 can share the weight of the overall displacement component and the transmission component, preventing the overall displacement component from tilting during operation. At the same time, it can better limit the sliding bar 7 and improve the stability of the lifting component in supporting the overall displacement component. It should be noted that a necessary gap should be reserved between the first roller 10 and its corresponding second roller 5 and the sliding bar 7 to prevent the relative position between the first roller 10 and its corresponding second roller 5 from changing under high temperature conditions, or the sliding bar 7 from deforming, which could cause the actuating lever 4 to become stuck.

[0042] The feeding assembly includes multiple pushing members 3, which are arranged sequentially along a first direction. Arranging multiple pushing members 3 along the first direction enhances the effectiveness of the material transport mechanism in pushing the material 14. Specifically, the anaerobic pyrolysis furnace has a material transport surface. During the pushing process, the pushing members and the transported material continuously push the carbon deposits on the transport surface within the anaerobic pyrolysis furnace, allowing the carbon deposits to be removed during the germination stage and preventing permanent carbon buildup on the transport surface, thus ensuring the efficiency of heat exchange within the anaerobic pyrolysis furnace. In this embodiment, the pushing members are plate-shaped, and their design can be adjusted according to actual industrial needs.

[0043] Specifically, the pusher 3 has an insertion part, and the rotating rod 11 is provided with an insertion hole corresponding to the insertion part. The insertion part passes through the insertion hole, and the pusher 3 can move axially along the insertion hole. A limit block 13 is provided at one end of the insertion part that passes through the insertion hole, and the limit block 13 is used to limit the insertion part. When the pusher 3 pushes the material 14, if the pusher 3 is stuck by the strip-shaped or block-shaped material 15, the pusher 3 can automatically move axially along the insertion hole to avoid the strip-shaped or block-shaped material 15, and then return to its original position. This can avoid the situation of material jamming when the pusher 3 pushes the material. The limit block 13 can limit the movement range of the pusher 3, ensuring that there is a suitable gap between the end of the pusher 3 away from the insertion part and the bottom surface of the oxygen-free pyrolysis furnace used to transport the material 14, and avoiding friction between the end of the pusher 3 away from the insertion part and the bottom surface of the oxygen-free pyrolysis furnace used to transport the material 14.

[0044] In detail, the transmission assembly includes a third roller 8 and a fourth roller 9, both mounted on the overall displacement assembly. The third roller 8 supports the actuating lever 4, and the fourth roller 9 cooperates with the third roller 8 to clamp the actuating lever 4. By using the third roller 8, the actuating lever 4 can be easily moved relative to the overall displacement assembly while being supported, increasing the smoothness of its movement. The fourth roller 9 cooperates with the third roller 8 to clamp the actuating lever 4, preventing it from disengaging from the third roller 8 during operation. The fourth roller 9 also limits the movement of the actuating lever 4, increasing the stability of the transmission assembly. It is important to note that a necessary gap must be maintained between the third roller 8, its corresponding fourth roller 9, and the actuating lever 4 to prevent changes in their relative positions under high temperatures or deformation of the actuating lever 4, which could lead to jamming.

[0045] Please see Figure 5 , Figure 10 and Figure 11The overall displacement assembly includes a displacement rod 6, and the transmission assembly includes a toggle rod 4. A pushing member is mounted on the displacement rod 6, and the toggle rod 4 is movable along a first direction on the displacement rod 6. The displacement rod 6 drives the pushing member and the toggle rod 4 to move, and the toggle rod 4 drives the pushing member to switch between a pushing position and a lifting position. The displacement rod 6 and the toggle rod 4 pass through the outside of the transport box into the interior of the anaerobic pyrolysis furnace. A sealing assembly 22 is provided on the outer wall of the transport box through the displacement rod 6 and the toggle rod 4 to seal the gaps between the displacement rod 6 / 4, the toggle rod 4, and the transport box. The transport box can be the body of the anaerobic pyrolysis furnace. By providing the sealing assembly 22, air can be prevented from entering the anaerobic pyrolysis furnace through the gaps between the displacement rod 6 / 4 or the toggle rod 4 and the anaerobic pyrolysis furnace body when the displacement rod 6 / 4 and the toggle rod 4 are moving, thus preventing safety hazards or even accidents. It also prevents pyrolysis gas leakage and environmental pollution. It is worth noting that the displacement rod 6 and the actuating rod 4 on the anaerobic pyrolysis furnace body should be designed with small cross-sections. The cross-sectional dimensions of the displacement rod should not exceed 180*180 mm, and the diameter of the actuating rod 4 should not exceed 100 mm. Such small cross-sectional dimensions make it very easy to seal using conventional sealing methods.

[0046] Specifically, the sealing assembly 22 includes a radial sealing ring 16, a clamping member 19, an axial sealing ring 16, a limiting assembly, and an elastic member 18. One side of the radial sealing ring 16 is in contact with the outer shell of the oxygen-free pyrolysis furnace body, and the other side of the radial sealing ring 16 is in contact with the clamping member 19. The elastic member 18 acts on the clamping member 19, which presses the radial sealing ring 16 against the outer shell of the oxygen-free pyrolysis furnace body. The clamping member 19 has a limiting part circumferentially arranged around the displacement rod 6 or the actuating rod 4 on the side away from the oxygen-free pyrolysis furnace body. A receiving groove is formed between the limiting part and the displacement rod 6 or the actuating rod 4. The axial sealing ring 16 is sleeved on the displacement rod 6 or the actuating rod 4 and received in the receiving groove. The limiting assembly is provided on the clamping member 19 and is used to limit the axial sealing ring 16 within the receiving groove. The axial sealing ring 16 fills the receiving groove radially along the displacement rod 6 or the actuating rod 4. In this embodiment, the number of axial sealing rings 16 is 3. Multiple axial sealing rings 16 can enhance the axial sealing effect of the axial sealing rings 16 on the displacement rod 6 or the actuating rod 4. The limiting assembly includes a sealing cap 20, bolts, and nuts. The sealing cap 20 has an extension portion that extends into the receiving groove. The extension portion is arranged circumferentially around the displacement rod or the actuating rod. By providing the extension portion, the axial sealing rings 16 can be held against the bottom of the receiving groove. The sealing cap 20 is connected to the clamping member 19 by bolts and nuts. With the above arrangement, the sealing assembly 22 can ensure its sealing effect when the displacement rod 6 or the actuating rod 4 moves radially or axially. In this embodiment, the elastic element 18 is a spring. Springs have the advantages of being flexible, having high elasticity, and being inexpensive. The type of elastic element 18 can be adjusted according to the actual use environment.

[0047] The overall displacement assembly further includes a first driving member 1 for driving the displacement rod 6 to move axially along the displacement rod 6, and the transmission assembly further includes a second driving member 2 for driving the actuating rod 4 to move axially along the actuating rod 4. The displacement rod 6 and the first driving member 1 are movably connected to prevent deformation of the overall displacement assembly after exposure to high temperatures, thus preventing changes in the relative position at the connection point with the first driving member 1 and ensuring the first driving member 1 can effectively move the displacement rod 6. Similarly, the second driving member 2 is movably connected to the actuating rod 4. In this embodiment, the first driving member 1 and the second driving member 2 can be hydraulic cylinders, which have advantages such as simple structure, reliable operation, and smooth movement. The types of the first driving member 1 and the second driving member 2 can be adjusted according to actual production needs.

[0048] Please see Figure 9 When the material transfer mechanism is working, if the pusher 3 is in the push position and the material 14 is on the movement trajectory of the pusher 3, the displacement rod 6, driven by the first drive 1, moves from position E to position F by a preset distance, and the pusher 3 pushes the material 14 forward by a preset distance. Then, the second drive 2 drives the actuating rod 4 to move relative to the displacement rod 6. The actuating rod 4 is equipped with an actuating element 21, which actuates the fork 12, causing the pusher 3 to move to the raised position. At this time, the material 14 is outside the movement trajectory of the pusher 3. The first drive 1 drives the displacement rod 6 to move from position F to position E by a preset distance, and after retracting, the pusher 3 switches to the push position. Similarly, the material transfer mechanism can also change the direction of material 14 by changing the switching sequence of the pushers 3, which will not be elaborated here. By repeating the above operations, the pushing and transfer of the material 14 can be completed. It is worth noting that the preset distance must match the number of pushers set along the first direction. Selecting a suitable preset distance can make the transfer component have a better transfer effect on the material. The number of pushers and the preset distance along the first direction can be adjusted according to the actual production situation.

[0049] In summary, by setting up the pusher 3 and the overall displacement assembly, when the material 14 is on the movement trajectory of the pusher 3, the overall displacement assembly can drive the pusher assembly to move along the first direction and push the material 14 forward in the first direction. When the pusher 3 is in the raised position, the material 14 is outside the movement trajectory of the pusher 3. The overall displacement assembly drives the pusher assembly to move in the opposite direction of the first direction, returning to the position before the pusher assembly. Since the material 14 is outside the movement trajectory of the pusher 3, the overall displacement assembly will not push the material 14 backward in the first direction when it moves in the opposite direction. The overall displacement assembly and the pusher 3 work together in this way to achieve long-distance and long-term movement of the material 14 through short-distance stepping, thus completing the pushing and transporting of the material 14. Because the material transport mechanism uses a reciprocating material transport method, the structure is simple and can adapt to high-temperature environments, avoiding thermal deformation and jamming in high-temperature environments. The material transport mechanism transports the material 14 continuously and stably.
