Abstract
Description
Technical Field
[0001] The present application relates to the technical field of solid waste recycling equipment, and in particular to a fully continuous waste tire oil refining production system and method. Background Art
[0002] With the progress and development of science and technology, the number of cars has gradually increased, and with it comes a large number of waste tires. This waste cannot be naturally degraded, and usually the tires need to be heated to crack them into oil and combustible gas to achieve the recycling of waste tires.
[0003] Common tire oil refining processes mainly include tire crushing, heating cracking, and tail gas condensation. For example, the patent document with publication number CN117343750A discloses a waste tire cracking and oil refining device. It mainly includes a feeding device, a cracking furnace, and a condenser. Crushed tires are placed in the cracking furnace through the feeding device. The cracking furnace cracks the tires to produce oil and gas, the oil is collected, and the gas enters the condenser. After condensation, the gaseous oil is cooled to liquid oil, completing the treatment of waste tires.
[0004] The continuous microwave cracking equipment and method disclosed in the patent document with publication number CN110791304B, a screw conveyor and two silos connected to the feed port of the screw conveyor are arranged at the feed port of the cracking furnace, and the two silos alternately convey materials into the screw conveyor. In this scheme, the silo is evacuated by a vacuum pump to reduce the entry of oxygen into the cracking furnace. In this scheme, affected by the vacuum equipment, the vacuum degree of the silo is up to 10Pa, that is, there is still a lot of air in the silo, and combustion will still occur during the tire cracking process, which has little effect on improving the oil yield. Moreover, when the silo is under negative pressure, there is a risk of backflow of cracking tail gas.
[0005] The patent document with publication number CN110229691B discloses a system for treating waste tires without oxygen, which squeezes out the air in the cracking furnace by high-temperature steam to reduce the oxygen content in the furnace. However, in the actual process, the water vapor is mixed with the air, which cannot effectively reduce the air in the cracking furnace, and the effect of improving the oil yield is still not obvious.
[0006] During the tire refining process, the oxygen entering the cracking furnace has a certain impact on the conversion rate of tire refining. Although the related art has reduced the oxygen entering the cracking furnace to a certain extent, combined with the above analysis, it can be seen that the schemes in the related art need to be further improved in the operation process or the deoxygenation effect. In addition, the high-temperature steam and vacuum equipment used in the related art have a high overall cost and cannot be operated continuously for a long time, which is not conducive to the continuous operation of the tire refining system. Summary of the invention
[0007] In order to improve the conversion rate of oil products in the tire oil refining process, the present application provides a fully continuous waste tire oil refining production system and method.
[0008] on the one hand:
[0009] The present application provides a fully continuous waste tire oil refining production system adopts the following technical solutions:
[0010] A fully continuous waste tire oil refining production system and method, comprising a feeding device and a cracking furnace, a deoxygenation device is also arranged between the feeding device and the cracking furnace, the deoxygenation device comprises a conveying pipe, an intercepting member and an extrusion member, the intercepting member is movably connected to the conveying pipe, the intercepting member is movable, the intercepting member can block the conveying pipe, the extrusion member is slidably fitted in the conveying pipe, and the extrusion member is provided with a vent hole, the conveying pipe is provided with a feed hole, the feed hole is located on a side of the intercepting member close to the extrusion member, and the feeding device is used to convey materials into the conveying pipe through the feed hole.
[0011] By adopting the above technical scheme, during the tire refining process, the feeding device works to input materials into the conveying pipe. Then the extrusion piece pushes the material close to the interception piece. As the extrusion piece continues to move, the material is squeezed, and the air between the gaps between the material particles is squeezed out from the air holes, thereby reducing the situation where the air follows the material into the cracking furnace, thereby reducing the situation where the material burns and consumes combustible gas or flammable oil in the cracking furnace, and improving the oil yield of the entire tire refining production system. In this application, the material is squeezed by physical extrusion (it is understood that the maximum pressure that can be achieved by my country's hydraulic technology is 80,000 tons. Under this pressure environment, it is enough to squeeze out most of the air between the gaps between the material particles. Compared with the vacuum and high-temperature steam technology in the related technology, its deoxidation efficiency is higher), so that the material is closely combined, the air between the material particles is squeezed out, and the situation where the air enters the cracking furnace with the material is reduced.
[0012] Compared with the high-temperature overall or vacuum method in the related technology, its actual feasibility and operability are higher. For example, the vacuum method needs to consider the sealing of the hopper, the structural strength, the negative pressure environment in the silo, etc. The above technology is difficult to implement under the current technical conditions and has poor stability. The physical extrusion used in this application is more stable. This feature has extraordinary significance in the operation of the tire refining system. Specifically: The startup and shutdown process of the entire tire refining system takes a long time. Generally, a large system requires four hours or more to fully start. The solution in this application has a simple and efficient structure and better system stability, thereby reducing system shutdowns, which can improve the efficiency of tire refining and reduce the production and operation costs of equipment.
[0013] Optionally, the length of the delivery pipe is not less than 3.5m.
[0014] By adopting the above technical solution, there is friction between the material and the side wall of the conveying pipe after the material is compacted. As the material is compacted again and again, the friction between the material and the conveying pipe continues to increase. When the force between the material and the conveying pipe is greater than the force required for the material to be compacted, the baffle is no longer needed to block and intercept the material. The friction between the compacted material and the conveying pipe is used to continuously compact the subsequent material with the cooperating extrusion parts, and the material is continuously pushed into the cracking furnace, which is convenient for the connected operation of the tire refining system.
[0015] Optionally, the extrusion piece is a cylindrical structure, and a plurality of the air holes are evenly spaced around the axis of the extrusion piece.
[0016] By adopting the above technical solution, a plurality of air holes are provided, which facilitates the discharge of air at different positions during the process of the extruder extruding the material.
[0017] Optionally, a rotating groove extending through the side wall of the air vent is provided in a direction parallel to the axis thereof, a cylindrical rotating column is provided in the rotating groove to rotate around the axis thereof, a mating groove is provided on the rotating column, and the mating groove is communicated with the air vent.
[0018] By adopting the above technical solution, the matching groove of the rotating column is connected to the air hole, and the side wall of the matching groove and the side wall of the air hole are connected to each other to form a complete air hole. The rotating column is rotated, and the matching groove and the air hole are staggered. At the same time, since other positions of the rotating column are filled into the air hole, the overall cross-sectional area of the air hole is reduced. A subdivided channel is formed between the side wall of the matching groove and the side wall of the rotating groove. It can also be understood that the complete air hole is formed into a subdivided channel and a small through hole respectively by the rotation of the rotating column. In this state, the aperture of the subdivided channel and the small through hole is small, so when the material is extruded in this state, it is not easy for the material to enter the air hole. Even if the material inevitably enters the air hole, the subdivided channel and the small through hole can be connected by rotating the rotating column to form a large-aperture air hole, thereby facilitating the dredging of the air hole.
[0019] Optionally, two rotating grooves are evenly spaced around the axis of the air vent, the overall diameter of the rotating column is equal to the diameter of the air vent, and the vertical distance between the axis of the rotating column and the axis of the air vent is equal to the radius of the air vent.
[0020] By adopting the above technical solution, the two rotating columns are rotated. When the two matching grooves are located on the sides away from each other, the side walls of the rotating columns abut against each other, so that the small through holes can be divided again, thereby further reducing the occurrence of materials being stuck in the holes.
[0021] Optionally, a circular trajectory line coaxial with the extrusion piece and tangent to the circular trajectory lines of the two rotating column side walls is defined as the first dividing line, and the extrusion piece is divided by the dividing piece to form an annular ring body and a column located inside the ring body, and the ring body and the column body can rotate relative to each other.
[0022] By adopting the above technical solution, the ring body and the column body rotate relative to each other, so that the divided small through holes are divided again, which reduces the hole diameter on the one hand and makes the hole distribution position on the extruded part more extensive on the other hand.
[0023] Optionally, the ring body is divided by a circular trajectory to form a fixed ring and a first rotating ring, the column body is divided by a circular trajectory to form a second rotating ring and a fixed column, and the rotating column is respectively connected to the first rotating ring and the second rotating ring.
[0024] By adopting the above technical solution, the first rotating ring and the second rotating ring are rotated to drive the rotating column to rotate. When the position of the matching groove is changed, a hole with a smaller aperture is formed between the matching groove and the fixed ring or the side wall of the fixed column, further reducing the occurrence of material entering the hole on the extrusion component.
[0025] Optionally, a connecting frame is provided on the first rotating ring, a driving assembly is provided on the connecting frame, the driving assembly includes gears and a driving ring, the gears are provided in plurality corresponding to the plurality of rotating columns, the driving ring is sleeved outside the plurality of gears and meshes with the plurality of gears.
[0026] By adopting the above technical solution, the driving assembly drives the multiple rotating columns to rotate synchronously, and the rotation of the multiple rotating columns is adjusted.
[0027] on the other hand,
[0028] The present application provides a fully continuous waste tire oil refining method using the following technical solutions:
[0029] A fully continuous waste tire oil refining method comprises a feeding step and a cracking step, wherein the feeding step comprises:
[0030] Deoxygenation: The air between the material particles is squeezed out through the deoxygenation device;
[0031] Transport: The material after oxygen removal is transported into the cracking furnace.
[0032] By adopting the above technical solution, the air between the gaps between the material particles is removed, thereby reducing the amount of oxygen entering the cracking furnace, thereby reducing the combustion of the material in the cracking furnace and improving the oil yield in the tire refining process.
[0033] Optionally, the deoxygenation step includes: placing the material between an intercepting member and an extruding member, the intercepting member blocking the movement of the material from one side, and the extruding member pushing and extruding the material from the other side to compact the material.
[0034] By adopting the above technical solution, the material is compacted by extrusion, thereby achieving the discharge of air between the gaps between the material particles. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0046] The following is combined with Figure 1-10 This application is described in further detail.
[0047] The embodiment of the present application discloses a fully continuous waste tire oil refining production system.
[0048] Reference Figure 1 and Figure 2 A fully continuous waste tire oil refining production system includes a feeding device 1, a deoxygenating device 2 and a cracking furnace 8, wherein the feeding device 1, the deoxygenating device 2 and the cracking furnace 8 are arranged in sequence, and the deoxygenating device 2 is arranged between the feeding device 1 and the cracking furnace 8. The feeding device 1 is used to transport the material (the material in this embodiment is the crushed tire particles) to the deoxygenating device 2. The deoxygenating device 2 is used to remove the air between the gaps between the material particles, and then transport the material to the cracking furnace 8 for cracking. After the material is cracked, combustible oil and tail gas are produced, the combustible oil is recovered into the oil tank, and the tail gas is transported to the subsequent process equipment for further treatment. The air in the gaps between the materials is removed by the deoxygenating device 2, thereby reducing the occurrence of combustion and consumption of combustible oil or combustible gas during the heating and cracking of the material, thereby improving the conversion rate of combustible oil.
[0049] Reference Figure 2 and Figure 3The deoxygenation device 2 includes a delivery pipe 21, an intercepting member 22 and an extrusion member 23. The delivery pipe 21 is a circular cylindrical structure, and the delivery pipe 21 is arranged horizontally. A support frame 24 for supporting the delivery pipe 21 is arranged below the delivery pipe 21. A sliding hole 26 is provided on the side wall of the delivery pipe 21, and the sliding hole 26 is connected to the inside of the delivery pipe 21. The intercepting member 22 is slidably connected to the delivery pipe 21 in a direction perpendicular to the delivery pipe 21, and the sliding intercepting member 22 can block the delivery pipe 21. A mounting block 27 is welded at a position corresponding to the intercepting member 22 on the delivery pipe 21, and a slide groove 28 is provided on the mounting block 27 at a position corresponding to the intercepting member 22, and the intercepting member 22 slides in the slide groove 28. On the one hand, the stability of the intercepting member 22 during sliding is improved, and on the other hand, it can prevent external air from entering the delivery pipe 21 from the gap between the intercepting member 22 and the sliding hole 26. In this embodiment, the intercepting member 22 is driven by a cylinder. The extrusion piece 23 is slidably connected in the conveying pipe 21 in a direction parallel to the length direction of the conveying pipe 21. In this embodiment, the extrusion piece 23 is also driven by a cylinder. A feed hole 29 is provided on the side wall of the conveying pipe 21, and the feeding device 1 is connected to the feed hole 29. The feeding device 1 can convey materials into the feed hole 29. The extrusion piece 23 is provided with a vent hole 9. When the extrusion piece 23 moves in a direction close to the intercepting piece 22, the air between the intercepting piece 22 and the extrusion piece 23 can be discharged from the vent hole 9.
[0050] Reference Figure 2 and Figure 3 When the tire refining system initially starts to operate, the intercepting piece 22 is inserted into the conveying pipe 21 to block the conveying pipe 21. The extrusion piece 23 is located on the side of the feed port away from the intercepting piece 22, and the feeding device 1 conveys the material into the feed port, and the material enters the conveying pipe 21 from the feed port. Then the extrusion piece 23 is moved to push the material close to the intercepting piece 22. As the extrusion piece 23 continues to move, the extrusion piece 23 squeezes the material. Under the action of pressure, the material is compacted, and the air in the gaps between the material particles is squeezed out and discharged from the air vent 9. In this embodiment, the air vent 9 is an annular hole provided on the outer wall of the extrusion piece 23 and extending through the sliding direction of the extrusion piece 23. It can also be understood that the diameter of the extrusion piece 23 is smaller than the inner wall of the conveying pipe 21, so that an air passage is formed between the extrusion piece 23 and the conveying pipe 21.
[0051] Reference Figure 2 and Figure 3 , then the extrusion member 23 is reset to the side of the feed port away from the interception member 22 , and then the feeding device 1 inputs the material again, which is extruded by the extrusion member 23 .
[0052] Reference Figure 2 and Figure 3It should be noted that as the material is compacted, the resistance between the material and the side wall of the conveying pipe 21 also increases. At the same time, as the amount of compacted material continues to increase. The resistance between the compacted material and the side wall of the conveying pipe 21 is defined as F, and the pressure of the extrusion member 23 on the material when the material is effectively compacted is defined as P1. When P1>F, the slidable intercepting member 22 can make the intercepting member 22 slide out of the conveying pipe 21. At this time, as the extrusion member 23 continues to push the material, the material will not move before it can be compacted. As the extrusion member 23 continues to move, the thrust of the oil cylinder on the extrusion member 23 can drive the compacted material to move in the conveying pipe 21, thereby allowing the compacted material to enter the cracking furnace 8.
[0053] Reference Figure 2 In order to ensure that the extrusion member 23 can effectively compact the material during the material conveying process, the length of the conveying pipe 21 in this embodiment is greater than 3.5m.
[0054] Reference Figure 2 and Figure 3 The deaerator 2 also includes a resistance-increasing tube 25, which is arranged perpendicular to the conveying pipe 21. One end of the conveying pipe 21 close to the cracking furnace 8 is connected to one end of the resistance-increasing tube 25. One end of the resistance-increasing tube 25 away from the conveying pipe 21 is connected to the feed port of the cracking furnace 8. A guide plate 3 is arranged between the resistance-increasing tube 25 and the conveying pipe 21, and the guide plate 3 is arranged at an angle with the length direction of the resistance-increasing tube 25 and the conveying pipe 21, and is used to guide the material to move into the resistance-increasing tube 25. By making the material move along the curved channel, the resistance in the process of pushing the compacted material is increased, so that the subsequent material can be effectively compacted. An opening is arranged at one end of the resistance-increasing tube 25 away from the cracking furnace 8, and a plugging flange is arranged at the opening. The plugging flange is a plate-like structure as a whole, and the plugging flange is fixed to the opening of the resistance-increasing tube 25 by screws, and is used to plug the opening of the resistance-increasing tube 25. When a blockage occurs during the material conveying process, the plugging flange can be removed to clean the materials in the conveying pipe 21 and the resistance-increasing tube 25.
[0055] Reference Figure 1 and Figure 2The feeding device 1 includes a silo 11 and a double screw conveyor 12 (LS-220). The silo 11 is located above the conveying pipe 21 and is used to store materials. A discharge port is arranged below the silo 11. The feed port of the double screw conveyor 12 is connected to the discharge port of the silo 11, and the discharge port of the double screw conveyor 12 is connected to the feed port on the side wall of the conveying pipe 21. Under the action of gravity, the material in the silo 11 has a tendency to move into the screw conveyor. After the material enters the double screw conveyor 12, the double screw conveyor 12 can drive the material to actively move into the conveying pipe 21. At the same time, when the double screw conveyor 12 stops running, the material can stop entering the conveying pipe 21. In the actual production process, the double screw conveyor 12 intermittently conveys materials into the conveying pipe 21. After the double screw conveyor 12 stops conveying materials, the extrusion member 23 moves to extrude the material.
[0056] The implementation principle of a fully continuous waste tire oil refining production system and method in the embodiment of the present application is: the air in the gaps between the material particles is squeezed out by the deoxygenation device 2 before the material enters the cracking furnace 8, thereby reducing the occurrence of air entering the cracking furnace 8, thereby reducing the burning of the material in the cracking furnace 8, and improving the oil yield in the tire oil refining system. Example
[0057] Reference Figure 4 and Figure 5 In this embodiment, the structure of the extrusion member 23 is different. In this embodiment, the extrusion member 23 is a cylindrical structure, and its outer wall is in contact with the inner wall of the delivery tube 21. The air holes 9 are cylindrical holes, and the air holes 9 penetrate the extrusion member 23 in a direction parallel to the axis of the extrusion member 23 to form an air passage. A plurality of air holes 9 are evenly spaced around the axis of the extrusion member 23 to facilitate the discharge of air close to the axis of the delivery tube 21.
[0058] Reference Figure 5 and Figure 6, a rotating groove 41 is provided on the side wall of the vent hole 9, and a rotating column 42 is provided in the rotating groove 41. The rotating groove 41 is an arc-shaped groove, the opening of the arc-shaped groove faces the vent hole 9, and penetrates along the axial direction of the extrusion piece 23. A rotating column 42 is provided in the rotating groove 41, and the rotating column 42 is a cylindrical structure as a whole, and the rotating column 42 rotates around the axis of the rotating groove 41 and fits in the rotating groove 41. A matching groove 421 is provided on the rotating column 42, and the matching groove 421 is an arc-shaped groove. The matching groove 421 is coaxial with the vent hole 9, and the radius is equal, so that the side wall of the matching groove 421 is tangent to the side wall of the vent hole 9. Moreover, when the matching groove 421 faces the vent hole 9, the side walls of the two matching grooves 421 and the side wall of the vent hole 9 match to form a complete cylindrical hole. The rotating column 42 is rotated to make the matching groove 421 on the rotating column 42 away from the vent hole 9, and a subdivided channel 422 can be formed between the side wall of the matching groove 421 and the side wall of the rotating groove 41. At the same time, the rotating column 42 can partially fill the vent hole 9 to form a small through hole 423 with a smaller cross-sectional area.
[0059] Reference Figure 5 and Figure 6 , it is defined that when the matching groove 421 is away from the vent hole 9, it is the working state of the extrusion piece 23. In the working state, the diameter area of the subdivided channel 422 and the small through hole 423 are both smaller than the particle size of the material, so as to reduce the occurrence of the material entering the subdivided channel 422 or the small through hole 423. When the material inevitably enters the subdivided channel 422 or the vent hole 9, the rotating column 42 can be rotated, and the rotating column 42 drives the material to move. When the matching groove 421 is connected to the vent hole 9, the space where the material in the aperture is located is increased, so that the material no longer presses against the vent hole 9 or the side wall of the matching groove 421, which facilitates the dredging of the air channel on the extrusion piece 23.
[0060] Reference Figure 5 and Figure 6 The diameter of the rotating column 42 is the same as the diameter of the side wall of the air hole 9, and the vertical distance between the axis of the rotating column 42 and the axis of the air hole 9 is equal to the radius of the air hole 9. When the extrusion piece 23 is in a working state, the side walls of the two rotating columns 42 are tangent to each other, further separating the air hole 9, reducing the cross-sectional area of the air channel, and further blocking the material from entering the air channel.
[0061] Reference Figure 6 and Figure 7, a circular trajectory line coaxial with the extrusion 23 and tangent to the side walls of the two rotating columns 42 is defined as the first dividing line 51, and the extrusion 23 is divided by the first dividing line 51 in its radial direction to form an annular ring body 53 and a column 54 coaxially arranged inside the ring body 53, and the ring body 53 and the column 54 can rotate with each other. When the extrusion 23 is in the working state, the small through hole 423 is composed of grooves on the column 54 and the ring body 53. In this state, the ring body 53 is rotated to divide the small through hole 423.
[0062] Reference Figure 5 and Figure 6 When the extrusion member 23 is in working state, the vent hole 9 is divided into subdivided channels 422 and small through holes 423, and the matching groove 421 is away from the small through hole 423. Figure 7 , define the two end points of the arc trajectory of the arc-shaped side wall of the matching groove 421 in this state as the dividing points, and define the circular trajectory coaxial with the extrusion member 23 and coinciding with the two dividing points as the second dividing line 52. The second dividing line 52 is formed into two corresponding to the two rotating columns 42. Under the action of the two second dividing lines 52, the ring body 53 is divided into a fixed ring 531 and a first rotating ring 532 coaxially arranged inside the fixed ring 531. The column 54 is divided into a second rotating ring 541 coaxially arranged inside the first rotating ring 532 and a fixed column 542 coaxially arranged inside the second rotating ring 541.
[0063] Reference Figure 6 and Figure 7 , the first rotating ring 532 can rotate relative to the fixed ring 531, and the second rotating ring 541 can rotate relative to the first rotating ring 532 and the fixed column 542. The first rotating ring 532 rotates, driving the rotating column 42 to rotate, so that the subdivided channel 422 between the first rotating ring 532 and the fixed ring 531 can be divided, reducing the cross-sectional area of the subdivided channel 422. The second rotating ring 541 rotates, so that the subdivided channel 422 between the second rotating ring 541 and the fixed column 542 can be divided.
[0064] Reference Figure 4 and Figure 8The fixed ring 531 and the fixed column 542 are fixedly connected to the piston rod of the oil cylinder for driving the extrusion member 23 to move. A blocking member 56 is provided on the fixed ring 531 and the fixed column 542 on one side close to the oil cylinder. The blocking member 56 is an arc-shaped structure, and two blocking members 56 are provided corresponding to the fixed ring 531 and the fixed column 542. The blocking member 56 is coaxially welded with the fixed ring 531 or the fixed column 542, wherein the inner side wall of the blocking member 56 on the fixed ring 531 extends in a direction close to the first rotating ring 532, so that the first rotating ring 532 abuts against the blocking member 56. The outer side wall of the blocking member 56 on the fixed column 542 extends in a direction close to the second rotating ring 541, so that the second rotating ring 541 abuts against the blocking member 56 to support the second rotating ring 541.
[0065] Reference Figure 8 and Fig. 9 The first rotating ring 532 and the second rotating ring 541 are provided with a connecting frame 55. For the convenience of description, the connecting frame 55 on the first rotating ring 532 is described here. The connecting frame 55 is an annular structure, and the connecting frame 55 is located on the side of the first rotating ring 532 or the second rotating ring 541 close to the oil cylinder. A connecting column is provided between the connecting frame 55 and the first rotating ring 532, and the two ends of the connecting column are respectively welded to the connecting frame 55 and the first rotating ring 532. Figure 5 After the ring body 53 and the column 54 are divided, the first rotating ring 532 forms a multi-section arc structure under the action of the air vents 9. The multi-section arc structure is connected by the connecting frame 55 to improve the stability of the first rotating ring 532 during rotation.

A rotating shaft is coaxially welded on the rotating column 42, and the other end passes through the connecting ring and extends to the side of the connecting ring away from the first rotating ring 532. The gear 71 is coaxially welded to the end of the rotating shaft away from the rotating column 42. The driving ring 72 is an annular structure, and the driving ring 72 is sleeved on the outside of the multiple gears 71, and a tooth groove that can mesh with the gear 71 is provided on the inner side wall of the driving ring 72.

One end of the pull rod 102 is welded to the driving ring 72, and the other end extends radially along the driving ring 72 to between the two limit blocks 101. The second rotating ring 541 rotates, driving the pull rod 102 to rotate. When the small through hole 423 between the second rotating ring 541 and the first rotating ring 532 is divided, the pull rod 102 abuts against one of the limit blocks 101. At this time, the second rotating ring 541 continues to rotate to drive the first rotating ring 532 to rotate, so that the subdivided channel 422 between the first rotating ring 532 and the fixed ring 531 is divided, completing the conversion of the extrusion member 23 to the working state.
[0070] Reference Figure 5 and Fig. 9 Similarly, when the material enters the air hole 9, the second rotating ring 541 is rotated, and the second rotating ring 541 rotates alone first. When the rotating column 42 on the second rotating ring 541 corresponds to the air hole 9, the pull rod 102 abuts against the limit block 101, thereby driving the second rotating ring 541 to rotate. After the rotating column 42 on the second rotating ring 541 rotates to the specified position, the two driving rings 72 can be controlled to rotate, so that the subdivided channel 422 is connected with the small through hole 423 to form a complete cylindrical structure of the air hole 9, which is convenient for cleaning the material.

[0072] The implementation principle of the fully continuous waste tire oil refining production system and method in the embodiment of the present application is: the extrusion piece 23 is divided to control the size of the air vent 9 to facilitate the discharge of air between the material gaps during the extrusion process, while taking into account the effect of dredging the air vent 9.
[0073] The present application also discloses a fully continuous waste tire oil refining production method.
[0074] A fully continuous waste tire oil refining production method, comprising:
[0075] S1 is used to load materials into the cracking furnace 8.
[0076] The steps of loading include:
[0077] S10, filling: feeding material into the conveying pipe 21 by the feeding device 1
[0078] S11, deoxidation, the air between the material particles is squeezed out through the deoxidation device 2:
[0079] The extruder 23 squeezes the material from one side, and the interceptor 22 blocks the movement of the material from the other side. With the cooperation of the two, the material is compacted and the air in the gap between the materials is squeezed out, thereby reducing the occurrence of oxygen entering the cracking furnace 8.
[0080] S11, increasing resistance: repeating the process of feeding and deoxidizing, so that the compacted material in the conveying pipe 21 increases continuously, until the force required to push the compacted material is greater than the pressure required for compacting the material.
[0081] S12, transporting, the intercepting member 22 is taken out from the transporting pipe 21; steps S10 and S11 are repeated, and the compacted material is gradually moved into the cracking furnace 8.
[0082] The conveying step includes a step of clearing the air hole 9. When the extruder 23 moves away from the cracking furnace 8, the rotating column 42 is rotated so that the matching groove on the rotating column 42 faces the air hole 9, thereby increasing the cross-sectional area of the air hole 9 and facilitating the cleaning of the material blocked in the air hole 9.
[0083] S2: The cracking furnace 8 heats the material, and the material is cracked to produce combustible oil and combustible gas, which are then collected to complete tire oil refining.
[0084] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
