Description

Technical Field

[0001] This application relates to the technical field of polymer treatment, and in particular to a device for producing oil and char from molten polymers and oily sludge. Background Technology

[0002] Waste fusible polymers and oily sludge usually require pyrolysis for harmless treatment. The commonly used pyrolysis reactor is usually a rotary kiln. However, rotary kilns can usually only process organic solid wastes with low viscosity during the pyrolysis phase change process, such as lignocellulose and municipal solid waste. They mainly target pyrolysis residual carbon as the product. The pyrolysis oil and gas are mostly in the state of mixed flue gas, which can only be co-fired to generate heat or even incinerated as waste. They are difficult to adapt to the continuous pyrolysis reaction conditions of polymers, resulting in low resource recovery and utilization rates. Summary of the Invention

[0003] To improve resource recycling rates, this application provides a device for producing oil and char from molten polymers and oily sludge.

[0004] The technical solution provided in this application for an oil and char production device from fusible polymers and oily sludge adopts the following: A device for producing oil and char from fusible polymers and oily sludge includes a reactor body and a frame. The reactor body includes multiple reactors mounted on the frame and spaced apart along the height of the frame. The reactors are arranged along the length of the frame and aligned at both ends. Multiple jackets adapted to the reactors and fitted onto the outside of the reactors are installed on the frame. Each reactor has a feed inlet on its upper side and a downward-facing discharge outlet on its lower side. The feed inlets and discharge outlets of the same reactor are spaced apart along the length of the reactor. The discharge outlets of adjacent reactors are directly opposite each other and fixedly connected to the same connecting pipe. A heat exchange component is provided in each jacket, and each reactor is provided with a first self-cleaning pushing component.

[0005] By adopting the above technical solution, the material is fed into the reactor through the reactor inlet at the top of the frame. At this time, the first self-cleaning pushing component in the reactor moves the material along the length of the reactor. The heat in the jacket is transferred to the inside of the reactor through the heat exchange component, thereby heating the material. The material moves in the reactor until it reaches the outlet and enters the next reactor through the connecting pipe, so that the material always moves along the length of the reactor. At the same time, the first self-cleaning pushing component continuously scrapes off the material adhering to the inner wall of the reactor while pushing the material to move, thereby improving the resource recycling rate.

[0006] Optionally, the feed inlet and the discharge outlet of the same reactor are located at opposite ends along the length of the reactor.

[0007] Optionally, the heat exchange assembly includes heat exchange plates spirally wound along the length of the reactor, the heat exchange plates being fixedly connected to the outer wall of the reactor, and the heat exchange plates being perpendicular to the length of the reactor.

[0008] By adopting the above technical solution, the heat in the jacket is transferred to the interior of the reactants through the heat exchange plates and the side wall of the reactor, which increases the contact area between the reactor and the heat and improves the heat exchange efficiency. This facilitates the provision of heat to the materials inside the reactor, and makes it easier for the materials to undergo full thermal decomposition in the reactor, thereby further improving the resource recovery rate.

[0009] Optionally, the first self-cleaning pushing assembly includes a main shaft passing through the reactor and coinciding with the reactor's rotation axis. A spiral blade is spirally wound and fixedly connected to the main shaft. A first scraper blade facing the inner wall of the reactor is provided on the outer side of the spiral blade. The first scraper blade contacts the inner wall of the reactor. A first motor fixedly connected to the reactor is installed at one end of the main shaft.

[0010] By adopting the above technical solution, the first motor drives the main shaft to rotate the spiral blades. At this time, the first scraper installed on the spiral blades rotates with the main shaft and pushes the material towards the discharge port. The material undergoes thermal decomposition, and the first scraper continuously scrapes off the material adhering to the inner wall of the reactor during the rotation process, thereby improving the resource recycling rate.

[0011] Optionally, a second self-cleaning pushing assembly is provided at one end of the main shaft at the upper end of the frame. The second self-cleaning pushing assembly includes a plurality of rotating shafts arranged on both sides of the main shaft. The rotating shafts are spaced apart along the length of the main shaft. A second scraper is slidably connected to one end of the rotating shaft away from the main shaft. A first spring is fixedly connected between the second scraper and the rotating shaft to press the second scraper against the inner wall of the reactor.

[0012] By adopting the above technical solution, during the rotation of the main shaft, the rotating shaft drives the second scraper to rotate with the main shaft and push the material to move towards the discharge port. At this time, the first spring presses the second scraper against the inner wall of the reactor, which facilitates the scraping off of the material adhering to the inner wall of the reactor, thereby further reducing and improving the resource recycling rate.

[0013] Optionally, the frame includes a frame body and a plurality of extension frames arranged along the height direction of the frame body. A reactor is installed on the frame body, and a plurality of reactors are installed on the extension frames. The reactors corresponding to the frame body have a plurality of feed ports that are adapted to the reactors on the extension frames. Adjacent extension frames are detachably connected, and the extension frames and the frame body are detachably connected.

[0014] By adopting the above technical solution, the reactors located in the same vertical plane on the stacked extension racks are interconnected, and each group of reactors is connected to the reactors on the rack body. This facilitates the simultaneous heat treatment of materials by multiple groups of reactors, thereby improving material processing efficiency. At the same time, the number of reactors in the heat treatment process can be increased or decreased according to the material requirements, further facilitating the improvement of resource recycling rate.

[0015] Optionally, both sides of the upper side of the frame body and the extension frame, which are arranged along the length direction of the frame body, are provided with sliding grooves, and both sides of the lower side of the extension frame, which are arranged along the length direction, are inserted into the corresponding sliding grooves and fixedly connected by bolts.

[0016] By adopting the above technical solution, the extension racks are fixed to each other and to the frame body by sliding grooves and bolts, which facilitates the installation and disassembly of the extension racks, meets the heat treatment requirements of materials, and further facilitates the improvement of resource recycling rate.

[0017] Optionally, the rotating shaft is inserted into the main shaft and rotatably connected to the main shaft. One end of the rotating shaft inserted into the main shaft is fixedly connected to a first bevel gear facing the rotation axis of the main shaft. A second bevel gear is meshed on one side of the first bevel gear. The main shaft is provided with a rotating component that drives the second bevel gear to rotate.

[0018] By adopting the above technical solution, the rotating component drives the second bevel gear to rotate the first bevel gear. At this time, the rotating shaft rotates with the first bevel gear, which makes it easy to adjust the angle of multiple rotating shafts at the same time, thereby changing the speed of pushing the material and facilitating the full thermal decomposition of the material.

[0019] Optionally, the rotating component includes a rotating shaft with one end inserted into the main shaft and passing through and fixedly connected to the second bevel gear, and a second motor fixedly connected to the reactor is installed at the end of the rotating shaft.

[0020] By adopting the above technical solution, the second motor drives the rotating shaft to rotate. At this time, the second bevel gear, which is fixedly connected to the rotating shaft, rotates, which facilitates driving the first bevel gear to drive the rotating shaft to rotate. This facilitates adjusting the angle of the second scraper, thereby adjusting the material movement rate and facilitating the full thermal decomposition of the material in the reactor.

[0021] Optionally, both ends of the second scraper are inserted into and slidably connected to extension plates. One end of each extension plate inserted into the second scraper is fixedly connected to a second spring on the side wall of the second scraper. A drive rod is inserted into each of the rotating shafts, with one end inserted into the second scraper and abutting against the side of the extension plate. The drive rod is slidably and rotatably connected to the rotating shaft. One end of the drive rod inserted into the second scraper is set to be conical. The other end of the drive rod passes through the first bevel gear and is threadedly connected to the first bevel gear. The drive rod is slidably connected to the main shaft.

[0022] By adopting the above technical solution, when the first bevel gear drives the rotating shaft to rotate, the drive rod threadedly connected to the first bevel gear moves towards or away from the second scraper under the rotation of the first bevel gear. At this time, the tip of the drive rod moves towards or away from the extension plate, which facilitates driving the extension plate to move towards or away from each other according to the rotation angle of the second scraper. This ensures that the projections of the second scraper in the vertical direction can always be connected, reducing the possibility that some materials on the inner wall of the reactor are difficult to scrape off due to the rotation of the second scraper, and improving the resource recycling rate.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The material is fed into the reactor through the reactor inlet at the top of the frame. At this time, the first self-cleaning pushing component in the reactor moves the material along the length of the reactor. The heat in the jacket is transferred to the inside of the reactor through the heat exchange component, thereby heating the material. The material moves in the reactor until it reaches the outlet and enters the next reactor through the connecting pipe. This ensures that the material always moves along the length of the reactor. While pushing the material, the first self-cleaning pushing component continuously scrapes off the material adhering to the inner wall of the reactor, improving the resource recycling rate. 2. The first motor drives the main shaft to rotate the spiral blades. At this time, the first scraper installed on the spiral blades rotates with the main shaft and pushes the material towards the discharge port. The material undergoes thermal decomposition, and the first scraper continuously scrapes off the material adhering to the inner wall of the reactor during the rotation process, thereby improving the resource recycling rate. 3. The second motor drives the rotating shaft to rotate. At this time, the second bevel gear, which is fixedly connected to the rotating shaft, rotates, which facilitates driving the first bevel gear to drive the rotating shaft to rotate. This facilitates adjusting the angle of the second scraper, thereby adjusting the material movement rate and facilitating the full thermal decomposition of the material in the reactor.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses an apparatus for producing oil and char from molten polymers and oily sludge. (Refer to...) Figure 1 and Figure 2 A device for producing oil and carbon from fusible polymers and oily sludge includes a frame 1 and a reactor 2 body mounted on the frame 1. The reactor 2 body includes multiple horizontal reactors 2, which are configured as 5 in this embodiment. The frame 1 includes a frame body 11 located at the lower end and multiple extension frames 12 located on the upper side of the frame body 11 and stacked on top of each other, which are configured as 2 in this embodiment.

[0030] Each extension frame 12 is equipped with two horizontally arranged reactors 2. Each reactor 2 has an inlet 21 and an outlet 22 on both sides in the vertical direction, with the inlet 21 located on the upper side. The inlet 21 and outlet 22 of the same reactor 2 are located at both ends along the length of the reactor 2. The reactors 2 on the extension frame 12 are aligned at both ends, and the outlet 22 and inlet 21 of two adjacent reactors 2 in the vertical direction are directly opposite each other and fixedly connected to the same connecting pipe 23.

[0031] A reactor 2 is installed in the middle of the frame body 11 in the width direction. The reactor 2 on the frame body 11 and the reactor 2 on the extension frame 12 are aligned at both ends. The reactor 2 on the frame body 11 has two inlets 21 on its upper side, which are respectively corresponding to the discharge ports 22 of the reactor 2 on the adjacent extension frame 12. The inlets 21 of the reactor 2 on the frame body 11 are also connected to the corresponding discharge ports 22 through connecting pipes 23. The connecting pipes 23 are fixedly connected to the side wall of the corresponding reactor 2.

[0032] The adjacent extension frame 12 and the frame body 11 can be detachably connected. The upper sides of the extension frame 12 and the frame body 11 are provided with sliding grooves 13 along the length direction. The lower side of the extension frame 12 is inserted into the corresponding sliding groove 13 and fixedly connected by bolts.

[0033] Reference Figure 1 and Figure 2 Both the extension frame 12 and the frame body 11 are fixed with jackets 14 adapted to the reactor 2. The reactor 2 is inserted into the corresponding jacket 14 and fixedly connected to both ends of the jacket 14. The reactor 2 is equipped with a first self-cleaning pushing component 3 to move the material, and the jacket 14 is equipped with a heat exchange component to transfer the heat in the jacket 14 to the inside of the reactor 2.

[0034] The material is fed into reactor 2 through the feed port 21 at the upper end of the frame 1. At this time, the first self-cleaning pushing component 3 in reactor 2 moves the material along the length of reactor 2. The heat in the jacket 14 is transferred to the inside of reactor 2 through the heat exchange component, thereby heating the material. The material continues to move along the length of reactor 2 until it reaches the discharge port 22 and enters the next reactor 2 through the connecting pipe 23. While pushing the material to move, the first self-cleaning pushing component 3 continuously scrapes off the material adhering to the inner wall of reactor 2 until the material is thermally decomposed.

[0035] The reactors 2 on the stacked extension racks 12, located in the same vertical plane, are interconnected, and each group of reactors 2 is connected to the reactors 2 on the rack body 11. This facilitates the simultaneous heat treatment of materials by multiple groups of reactors 2. At the same time, the extension racks 12 are fixed to each other and to the rack body 11 by sliding grooves 13 and bolts, which facilitates the installation and disassembly of the extension racks 12. The number of reactors 2 in the heat treatment process can be increased or decreased according to the material requirements to meet the heat treatment needs of the material and improve the resource recycling rate.

[0036] Reference Figure 2 The heat exchange assembly includes heat exchange plates 4 spirally wound along the length of the reactor 2 on the outer wall of the reactor 2. The heat exchange plates 4 are fixedly connected to the outer wall of the reactor 2 and are perpendicular to the length of the reactor 2.

[0037] The first self-cleaning extrusion assembly 3 includes a main shaft 31 passing through both ends of the reactor 2 along its length. The main shaft 31 is horizontal and rotatably connected to the reactor 2. The main shaft 31 coincides with the rotation axis 63 of the reactor 2, and spiral blades 32 arranged along the length of the main shaft 31 are spirally wound on the main shaft 31.

[0038] A first scraper 33 is fixedly connected to the side of the spiral blade 32 near the inner wall of the reactor 2. In this embodiment, the first scraper 33 is set as a high temperature resistant flexible carbon material, and the side of the first scraper 33 away from the main shaft 31 contacts the inner wall of the reactor 2. A first motor 34 is installed at one end of the main shaft 31 and fixedly connected to the outer wall of the reactor 2.

[0039] Heat in jacket 14 is transferred to the interior of reactants through heat exchange plates 4 and the side wall of reactor 2, increasing the contact area between reactor 2 and heat and improving heat exchange efficiency. The first motor 34 drives the main shaft 31 to rotate the spiral blades 32. At this time, the first scraper 33 installed on the spiral blades 32 rotates with the main shaft 31 and pushes the material towards the discharge port 22. The material undergoes thermal decomposition. During the rotation, the first scraper 33 continuously scrapes off the material adhering to the inner side wall of reactor 2, thereby improving the resource recovery rate.

[0040] When the material enters the reactor 2, it will sink to the bottom due to gravity. Since the temperature at the bottom of the reactor 2 is high, the material will be heated into a highly adhesive fluid such as hot tar. When the spiral blade 32 and the first scraper 33 propel the tar, the material will fall back to the bottom of the reactor 2. The first scraper 33 will experience some wear, and some tar will adhere to the surface of the first scraper 33. It will be carried by the first scraper 33 to contact the upper wall of the reactor 2. Since there is no material above the reactor 2 to exchange heat with it, the temperature will be high, causing the tar adhering to the first scraper 33 to be carbonized, thereby repairing the wear of the first scraper 33, completing the carbonization repair process, and extending the service life of the first scraper 33.

[0041] Reference Figure 2 and Figure 3 In the reactor 2 located at the upper end of the frame 1, the main shaft 31 is provided with a second self-cleaning pushing assembly 5 at the end away from the first motor 34. The second self-cleaning pushing assembly 5 includes multiple rotating shafts 51 rotatably connected to the main shaft 31 and facing a rotation axis 63 away from the main shaft 31. The rotating shafts 51 are evenly distributed along a spiral line around the axis of the main shaft 31. A guide slider 52 is fixedly connected to the end of the rotating shaft 51 away from the main shaft 31. A second scraper 53 parallel to the guide slider 52 is provided on the side of the guide slider 52 away from the rotating shaft 51. In this embodiment, the second scraper 53 is set as a high-temperature resistant flexible carbon material. A mounting bracket 54 is fixedly connected to the side of the second scraper 53 near the guide slider 52.

[0042] Reference Figure 3 The mounting bracket 54 has two fixedly connected sliding rods 55 at its ends near the guide slider 52, which face the rotating shaft 51 and are parallel to it. The ends of the sliding rods 55 away from the mounting bracket 54 pass through the guide slider 52 and are slidably connected to it. A limit nut 56 is threadedly connected to one end of the sliding rod 55 passing through the guide slider 52, and a first spring 57 is sleeved on the end of the sliding rod 55 near the mounting bracket 54. One end of the first spring 57 is fixedly connected to the mounting bracket 54, and the other end is fixedly connected to the guide slider 52; the first spring 57 is always in a compressed state.

[0043] During the rotation of the main shaft 31, the rotating shaft 51 drives the second scraper 53 to rotate with the main shaft 31 and pushes the material towards the discharge port 22. At this time, the first spring 57 presses the second scraper 53 against the inner wall of the reactor 2, which facilitates the scraping of the material adhering to the inner wall of the reactor 2. During the contact between the second scraper 53 and the material, some tar will adhere to the surface of the second scraper 53 and be carried by the second scraper 53 to contact the upper wall of the reactor 2. Since there is no material above the reactor 2 to exchange heat with it, the temperature will be high, which will carbonize the tar adhering to the second scraper 53, thereby repairing the wear of the second scraper 53 and completing the carbonization repair process.

[0044] One end of the rotating shaft 51 near the main shaft 31 is inserted into the main shaft 31 and sleeved and fixedly connected to the first bevel gear 6. One side of the first bevel gear 6 is meshed with a vertical second bevel gear 61. Two adjacent second bevel gears 61 face away from each other and are fixedly connected to the same rotating ring 62. The rotating ring 62 is rotatably connected to the inner wall of the main shaft 31. The main shaft 31 is provided with a rotating component that drives the second bevel gear 61 to rotate.

[0045] Reference Figure 2 and Figure 3 The rotating component includes a rotating shaft 63, one end of which is inserted into the main shaft 31 and passes through the center of the second bevel gear 61 and is fixedly connected to the second bevel gear 61. A second motor (not shown in the figure) is installed at the end of the rotating shaft 63 located outside the reactor 2 and is fixedly connected to the outer wall of the reactor 2.

[0046] The second motor drives the rotating shaft 63 to rotate. At this time, the second bevel gear 61, which is fixedly connected to the rotating shaft 63, drives the rotating ring 62 to rotate, thereby driving the first bevel gear 6 to drive the rotating shaft 51 to rotate, so as to adjust the angle of the second scraper 53 and thus adjust the material movement rate.

[0047] Both ends of the second scraper are provided with extension plates 64. A through cavity 531 is opened on the second scraper. The ends of the extension plates 64 that are close to each other are inserted into the cavity 531 and fixedly connected to the same second spring 65, which is always in a compressed state. A drive rod 66 is inserted into and threadedly connected to the middle of the second scraper near the mounting bracket 54. One end of the drive rod 66 is inserted into the cavity 531 and is set as a tip whose width gradually decreases towards the side away from the rotating shaft 51. The ends of the extension plates 64 that are close to each other abut against the side wall of the tip.

[0048] The other end of the drive rod 66 passes through the mounting bracket 54, the guide slider 52 and the rotating shaft 51 and is located in the main shaft 31. The cross-section of the end of the drive rod 66 located in the main shaft 31 is set to square. A fixed plate 67 adapted to the drive rod 66 is fixedly connected in the main shaft 31. The end of the drive rod 66 inserted into the main shaft 31 passes through the drive plate and is slidably connected to the fixed plate 67.

[0049] When the first bevel gear 6 drives the rotating shaft 51 to rotate, the drive rod 66, which is threadedly connected to the second scraper 53, moves toward or away from the second scraper 53 under the rotation of the second scraper 53. At this time, the tip of the drive rod 66 moves toward or away from the extension plate 64, so that the extension plate 64 can be driven to move toward or away from each other according to the rotation angle of the second scraper 53. This ensures that the projections of the second scraper 53 in the vertical direction can always be connected, reducing the possibility that some material on the inner wall of the reactor 2 will be difficult to scrape off due to the rotation of the second scraper 53.

[0050] The implementation principle of the fusible polymer and oil-containing sludge oil-to-carbon device in this application embodiment is as follows: the material is fed into the reactor 2 through the feed port 21 at the upper end of the frame 1. At this time, the spiral blades 32 in the reactor 2 move the material along the length direction of the reactor 2 and continuously scrape off the material adhering to the inner side wall of the reactor 2. The heat in the jacket 14 is transferred to the inside of the reactor 2 through the heat exchange plate 4, thereby heating the material. The material always moves along the length direction of the reactor 2 until the material reaches the discharge port 22 and enters the next reactor 2 through the connecting pipe 23 until the pyrolysis of the material is completed.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
