Description

Technical Field

[0001] The invention relates to the technical field of reactors, in particular to a pyrolysis reactor with central envelopes connected in series and capable of rotating independently. Background Art

[0002] The pyrolysis reactor is a device specially used for the pyrolysis process, which is widely used in the fields of chemical industry, environmental protection and energy. Pyrolysis refers to the process of decomposing organic matter into small molecular compounds by high temperature heating under oxygen-free or oxygen-deficient conditions. This technology can be used in a variety of application scenarios such as waste treatment, biomass conversion and plastic recycling.

[0003] The pyrolysis reactor with a central seal in series and capable of rotating independently is composed of two or more reaction chambers, and each reaction chamber is connected by a sealing device. Since the reaction chambers are arranged in series along the axial direction, the material can enter the next reaction chamber in sequence from one reaction chamber, thereby gradually completing the pyrolysis process, and each reaction chamber of this reactor can rotate independently. Although this allows the material to be heated evenly in each reaction chamber, gaseous products will be produced after the pyrolysis of the material, and the air pressure inside the reactor will gradually increase, which will cause leakage at the connection between each reaction chamber and the sealing device under high pressure, which will not only affect the production efficiency, but may also pose a threat to the environment and personnel safety.

[0004] Based on the above situation, the present invention proposes a pyrolysis reactor with a middle envelope having good sealing effect and being connected in series and rotatable separately. Summary of the invention

DETAILED DESCRIPTION

[0037] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0038] Embodiment 1: A pyrolysis reactor with a central envelope connected in series and capable of rotating independently, such as Figure 1-Figure 6 As shown, it includes a frame 1, a reactor 11, a dual-axis motor 1101, a spur gear set 1102, a sleeve 12, a sealing inner plate 1201, a spiral frame 13, an expansion block 14, a storage cylinder 15, a guide tube 16 and a clamping rod 17. The left and right sides of the frame 1 are rotatably connected to the reactor 11, and the middle part of the frame 1 is fixedly connected to the dual-axis motor 1101, wherein the spur gear set 1102 includes a gear ring and a gear, and the gear ring is meshed with the gear, and the output ends on the left and right sides of the dual-axis motor 1101 are fixedly connected to the gears in the two spur gear sets 1102, the outside of the reactor 11 is fixedly connected to the gear rings in the two spur gear sets 1102, and the frame 1 is fixedly connected to the gear rings in the two spur gear sets 1102. The sealing sleeve 12 is fixedly connected to the inner part, and the left and right sides of the inner part of the sealing sleeve 12 are rotatably connected, the sealing inner plate 1201 is in contact with the adjacent reactor 11, the reactor 11 is fixedly connected with a spiral frame 13, the inner side of the sealing inner plate 1201 is fixedly connected with an expansion block 14, the inner side of the sealing inner plate 1201 is fixedly connected with a storage cylinder 15 which is evenly distributed around the circumference, the storage cylinder 15 is fixedly connected to the adjacent expansion block 14 and is connected with a guide tube 16, the two expansion blocks 14 are fixedly connected with a clamping rod 17 which is evenly distributed around the circumference on the sides away from each other, the clamping rod 17 is slidably connected to the sealing inner plate 1201, and the clamping rod 17 is slidably connected to the reactor 11.

[0039] like Figure 5 and Figure 6 As shown, the sides of the two reaction kettles 11 close to each other are both provided with circumferentially equidistantly distributed slots.

[0040] When workers need to pyrolyze various organic wastes, they can first add an appropriate amount of material through the right side feed port of the right side reactor 11, then start the dual-axis motor 1101 and drive the gears in the spur gear set 1102 to rotate, and the rotation of the gears will also drive the ring gears in the spur gear set 1102, the reactor 11, the spiral frame 13 and the sealed inner plate 1201 to rotate, thereby transporting and turning the material to the left. During this period, the reactor 11 will heat the material and pyrolyze it, and the temperature inside the reactor 11 will gradually increase. At this time, the water in the storage cylinder 15 will gradually evaporate and generate water vapor, and the water vapor will enter the expansion block 14 through the guide tube 16 and expand it to block the gap between the reactor 11 and the sealed inner plate 1201. However, as the material is gradually pyrolyzed and the corresponding gaseous products are generated, the air pressure inside the reactor 11 also increases, making it easier for the gas in the reactor 11 to squeeze and deform the expansion block 14 and pass it from the reactor 11 to the sealing inner plate 1201. The gap between the sealed inner plates 1201 leaks outward, but since the water in the storage cylinder 15 is also gradually evaporating, water vapor is continuously generated and the air pressure in the expansion block 14 is increased, so that the expansion block 14 can still remain close to the reactor 11 under high pressure and effectively prevent material leakage. The expansion of the expansion block 14 will also drive the clamping rod 17 to insert into the clamping slot on the adjacent reactor 11, thereby improving the connection effect between the reactor 11 and the sealed inner plate 1201, avoiding relative rotation and leakage between the reactor 11 and the sealed inner plate 1201. When the material is pyrolyzed and transported to the left discharge port of the left reactor 11, the worker can turn off the dual-axis motor 1101 and take out the solid product after pyrolysis. After that, as the temperature inside the reactor 11 drops, the water vapor gradually cools down and liquefies, the expansion block 14 then deforms, shrinks and returns to its original state, and the clamping rod 17 also moves in the opposite direction to reset and detaches from the clamping slot on the reactor 11.

[0041] Embodiment 2: On the basis of Example 1, Figure 7-Figure 9 As shown, a pressure relief mechanism is also included, which is arranged on the reactor 11. The pressure relief mechanism includes a connector 2, a suction head 21, a filter 22, a connecting pipe 23, a limiting ring 24, a baffle frame 25 and a compression spring 26. The suction head 21 is fixedly connected to the middle of the reactor 11, and the inner side of the suction head 21 is fixedly connected and connected to the air inlet heads equidistantly distributed around the circumference. The suction head 21 is rotatably connected to the connector 2 on the outside, and there is a cavity between the suction head 21 and the connector 2. Filters 22 are fixedly connected to the left and right sides of the bottom of the frame 1, and a connecting pipe 23 is fixedly connected and connected between the filter 22 and the connector 2. A limiting ring 24 is fixedly connected to the inside of the connecting pipe 23, and a baffle frame 25 is slidably connected to the middle of the limiting ring 24, and a compression spring 26 is fixedly connected between the baffle frame 25 and the limiting ring 24.

[0042] When the reactor 11 rotates under the action of the dual-axis motor 1101, the suction head 21 will also rotate with the reactor 11. When the air pressure in the reactor 11 rises to a level beyond the safe range, the gaseous products in the reactor 11 will first enter the cavity between the suction head 21 and the connector 2 through the suction head 21, and then enter the connecting pipe 23 from the cavity and squeeze the baffle frame 25. The baffle frames 25 on the left and right sides will then move back to back and separate from the limiting ring 24. The compression spring 26 will then be compressed, and part of the gaseous products will pass through the limiting ring 24 and the connecting pipe 23 and enter the filter 22. The filter 22 will remove harmful gases in the gaseous products. After filtering out, the gaseous product will continue to be transported to the external collection device, and the air pressure in the reactor 11 will drop immediately. When the air pressure in the reactor 11 returns to a safe range, the baffle frames 25 on the left and right sides will move toward each other and reset under the action of the compression spring 26 and block the channel in the middle of the limit ring 24, so that the air pressure inside the reactor 11 can be maintained in a stable state, thereby effectively avoiding leakage and safety problems caused by excessive air pressure inside the reactor 11. The air inlet heads equidistantly distributed on the circumference of the suction head 21 are to avoid a single air inlet head being blocked by materials when it rotates to the bottom of the reactor 11, thereby losing the pressure relief effect.

[0043] like Fig.10 As shown, it also includes a knocking mechanism, which is arranged on the frame 1. The knocking mechanism includes a top block 3, a magnetic guide plate 31, a support frame 32, a spring piece 33 and a vibration block 34. The four support frames 32 are respectively fixed to the front and rear parts on the left and right sides of the frame 1. The upper part of the support frame 32 is slidably connected with the magnetic guide plate 31, and the spring piece 33 is fixed between the magnetic guide plate 31 and the support frame 32. The top blocks 3 distributed equidistantly around the circumference are fixedly connected to the sides of the left and right reactors 11 away from each other. The top blocks 3 are squeezed and matched with the magnetic guide plates 31. The inside of the reactor 11 is fixed with uniformly distributed vibration blocks 34 through a pull rope, and the magnetic guide plates 31 are magnetically matched with the vibration blocks 34.

[0044] like Fig.10 As shown, the top blocks 3 on the left and right sides that are close to each other are both provided with curved surfaces.

[0045] When the reactor 11 rotates under the action of the dual-axis motor 1101, the top block 3 will also rotate with the reactor 11. When the top block 3 rotates to contact and squeeze the adjacent magnetic guide plate 31, the magnetic guide plates 31 on the left and right sides will drive the vibration blocks 34 adsorbed thereon to move toward each other, and the spring pieces 33 will be compressed immediately. When the top block 3 rotates to separate from the adjacent magnetic guide plates 31, the magnetic guide plates 31 on the left and right sides will drive the vibration blocks 34 adsorbed thereon to move backwards under the action of the spring pieces 33, thereby driving the vibration blocks 34 to swing back and forth and knock and stir the materials inside, thereby breaking up the agglomerated materials and evenly dispersing them, so that the materials can be evenly heated and pyrolyzed.

[0046] like Figure 11-Figure 15 As shown, it also includes a conveying mechanism, which is arranged on the sealing inner plate 1201. The conveying mechanism includes a rotating frame 4, a slider 41, an asbestos cloth 42, a mounting plate 43, a friction block 44, a friction wheel 45, a winding disk 46 and a metal pull rope 47. The mounting plate 43 is fixed to the inner side of the sealing inner plate 1201. The right side of the mounting plate 43 is rotatably connected to the rotating frame 4 with equidistant distribution around the circumference. The right side of the rotating frame 4 is slidably connected to the slider 41. The rotating frame 4 and the slider 41 are equidistantly distributed around the circumference. Asbestos cloth 42 is fixedly connected between 1 and the sealing inner plate 1201, two friction blocks 44 are fixedly connected inside the envelope 12, a friction wheel 45 is rotatably connected inside the sealing inner plate 1201, the friction wheel 45 is in contact with the adjacent friction block 44, a winding disk 46 is fixedly connected to the right side of the friction wheel 45, and metal pull ropes 47 are slidably connected between the sliders 41 distributed equidistantly around the circumference, one end of the metal pull rope 47 is fixedly connected to the sealing inner plate 1201, and the other end of the metal pull rope 47 is wound around the winding disk 46.

[0047] like Fig.12 As shown, the left and right friction blocks 44 are staggered in vertical arrangement.

[0048] When the reactor 11 and the spiral rack 13 on the left transport the material to the sealed inner plate 1201 on the left, since there is no spiral rack 13 in the area where the envelope 12 and the sealed inner plate 1201 are located, the material may accumulate on the sealed inner plate 1201 on the left. However, the rotation of the reactor 11 on the left will also drive the sealed inner plate 1201 on the left and its internal friction wheel 45, winding disk 46 and other components to rotate. When the friction wheel 45 rotates to contact the adjacent friction block 44, the friction wheel 45 itself will rotate under the action of friction, and the winding disk 46 will also rotate with the friction wheel 45 and reel in the metal pull rope 47. The reeling of the metal pull rope 47 on the left will drive the rotating frame 4 and the slider 41 distributed evenly around the circumference to rotate inward. During this period, the slider 41 will also slide away from the rotating frame 4. At this time, the rotating frame 4 and the slider 41 distributed evenly around the circumference will appear tilted and present a truncated cone shape. The material on the inner plate 1201 will slide to the left along the inclined rotating frame 4 and the slider 41, and the asbestos cloth 42 between the rotating frame 4 and the slider 41 and the sealed inner plate 1201, which are evenly distributed on the circumference, will unfold and prevent the material from being stuck in the gap between the two adjacent rotating frames 4 and the gap between the rotating frame 4 and the sealed inner plate 1201. When the friction wheel 45 rotates to separate from the friction block 44, the lower rotating frame 4 and the slider 41 will rotate downward and reset under the action of their own gravity, and the lower slider 41 will also slide in the opposite direction and reset. The reset of the lower rotating frame 4 and the slider 41 will also drive the friction wheel 45 and the winding disk 46 to rotate in the opposite direction and reset through the metal pull rope 47. The same is true when the friction wheel 45 inside the sealed inner plate 1201 on the right side contacts the friction block 44, thereby causing the material to slide to the left and enter the reactor 11 on the left, thereby preventing the material from accumulating on the two sealed inner plates 1201 and affecting subsequent pyrolysis.

[0049] like Fig.16 As shown, a stirring mechanism is also included, which is arranged on the spiral frame 13. The stirring mechanism includes a rotating block 5 and a rotating shaft 51. The rotating shafts 51 staggered in the front and back are all fixedly connected to the inside of the spiral frame 13, and the rotating block 5 is rotatably connected to the outside of the rotating shaft 51.

[0050] like Fig.16 As shown, the mass distribution of the rotating block 5 on the upper and lower sides is uneven.

[0051] When the spiral frame 13 rotates with the reactor 11, the rotating block 5 and the rotating shaft 51 will also rotate with the spiral frame 13. Since the mass distribution of the rotating block 5 is uneven and the lower part is heavier, every time the spiral frame 13 drives the rotating block 5 to rotate 180°, the rotating block 5 will flip over due to the uneven mass distribution. In this way, the material inside the reactor 11 can be stirred by the rotation of the rotating block 5, so that the material can be evenly heated and pyrolyzed.

[0052] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
