Description
Technical Field
[0001] This invention relates to the field of walnut oil production technology, specifically to a plasticizer removal device in the walnut oil production process. Background Technology
[0002] Walnut oil is an edible oil extracted by pressing walnuts. The process of peeling, shelling, drying, and finally pressing walnuts involves multiple steps, which are now mostly automated using mechanical equipment. However, some contamination is inevitable during these processes, the most common of which is plasticizers. In recent years, the problem of excessive plasticizers in edible oils has been frequently reported, seriously affecting the safety of oil products.
[0003] Currently, methods for removing plasticizers from edible oils include adsorption with adsorbents, thermal decomposition, photocatalytic decomposition, and biological treatment. However, due to the special nature of edible oils, some highly efficient chemical methods are not suitable and can easily cause secondary pollution. Conventional methods require multiple steps, are cumbersome, and during thermal decomposition, plasticizers usually enter the air directly, resulting in slow discharge and potential secondary pollution and contamination of the processing area. Summary of the Invention
[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a plasticizer removal device for walnut oil production process, comprising a shell and a bracket fixedly installed at the bottom of the shell, wherein a side plate is fixedly connected to the top end of the bracket;
[0005] Heating component, which is fixedly installed at the bottom of the housing;
[0006] The feeding assembly is located on the top of the housing, and a motor is fixedly connected to the top of the feeding assembly;
[0007] The casing includes an outer shell, which is fixedly connected to a support frame. The bottom of the outer shell is fixedly connected to a heating component. A cylindrical body is fixedly connected to the middle of the inner part of the outer shell. The cylindrical body, the intermediate cylinder, and the outer shell form a flow channel. When walnut oil is added to the cylinder, the heating component at the bottom operates, making the middle part the heating and decomposition zone for walnut oil. This allows the walnut oil to be heated in the core area, ensuring that the plasticizer is fully decomposed. At the same time, the flow channel extends the residence time of the decomposed gas in the equipment, making the heating and decomposition process more thorough and avoiding the problem of plasticizer residue caused by insufficient processing time. It guides the decomposed gas to flow in an orderly manner, which not only reduces the turbulent collision of gas in the equipment and reduces energy loss, but also allows the gas to enter the outer filtration and adsorption zone evenly. By setting a filter plate between the intermediate cylinder and the outer shell, residual plasticizers and other impurities in the flowing gas can be efficiently captured, improving the purity of the final walnut oil. An intermediate cylinder is set inside the outer shell and is sleeved on the outside of the cylindrical body. Filter plates are fixedly connected to the inner wall of the outer shell. There are multiple filter plates, which are located in the gap between the intermediate cylinder and the outer shell.
[0008] Preferably, there are multiple side plates, which are evenly distributed around the shell. The inner side of the side plate contacts the outer side of the shell. A support ring is provided on the top of the side plate, and a support rod is fixedly connected to the top of the support ring. The support rod is fixedly connected to the feeding assembly. A cooling pipe is fixedly connected to one end of the shell near the inside of the motor. During the decomposition of walnut oil plasticizer, high-temperature gas carrying plasticizer components is generated. When these gases flow upward, the cooling pipe at the top can quickly cool them down, causing some of the easily condensable plasticizer components to condense into liquid, which is convenient for subsequent collection and processing, and improves the separation efficiency of plasticizer.
[0009] Preferably, multiple filter plates are evenly arranged in the gap between the outer shell and the intermediate cylinder. A buffer block is fixedly connected to the middle of the inner bottom side of the outer shell, and a fixing plate is fixedly connected to the inner bottom side of the outer shell. The fixing plate and fixing ring at the bottom of the outer shell are connected to the bottom heating component. The heat provided by the heating component is transferred to the fixing ring and fixing plate through the bottom, raising their temperature. When gas or liquid flows through, it can be reheated or kept warm, avoiding heat waste. For plasticizers that are not completely decomposed, they can be further decomposed under the residual heat when flowing through the heated fixing ring and fixing plate, improving the thoroughness of plasticizer removal. At the same time, this heat conduction method makes the internal temperature distribution of the equipment more uniform and reduces [the risk of heat loss]. The presence of localized low-temperature zones ensures the stability of the overall treatment effect. Multiple fixing plates are evenly distributed around the buffer block. Multiple fixing rings are fixedly connected to the bottom inner side of the outer shell, evenly arranged on the same horizontal plane. Multiple partitions are fixedly connected to the outer side of the cylinder, evenly distributed around the cylinder. A discharge pipe is fixedly connected to the outer side of the outer shell near the cooling pipe, communicating with the outer shell. The filter plates have hexagonal filter holes evenly distributed on the filter plates. The bottom of the outer shell... The system is fixedly connected with multiple clamping plates, evenly distributed at the bottom of the outer shell. A guide tube is fixedly connected to the inner wall of the outer shell, and a limiting tube is fixedly connected to the top of the intermediate cylinder. Both ends of the limiting tube and the guide tube are tapered, with larger diameters at both ends. During the decomposition of walnut oil plasticizers, high-temperature gas carrying plasticizer components is generated. This gas rises and then flows sequentially through the gap between the intermediate cylinder and the main cylinder, and the gap between the outer shell and the intermediate cylinder. This allows the gas to pass through multiple filter plates, finally entering the gap between the guide tube and the outer shell from the gap between the limiting tube and the guide tube. This flow channel provides a directional guiding path for the plasticizer gas, preventing... The disordered diffusion of gas during the rising process is eliminated, allowing more plasticizer gas to concentrate and flow to the top area, reducing processing dead zones caused by flow dispersion. The cooling pipe and the gas guided by the flow channel form a vertical cross contact mode, increasing the contact area and contact time between the two, reducing gas flow around, ensuring that more plasticizer components are condensed and captured, and improving the purification efficiency of single-stage cooling. The condensate flows along the inner wall of the shell and is discharged from the discharge pipe. The guide cylinder is set outside the limiting cylinder. The end of the limiting cylinder away from the middle cylinder is fixedly connected to the inner top of the shell. There is a gap between the end of the guide cylinder away from the inner wall of the shell and the top of the shell. The connection between the guide cylinder and the inner wall of the shell is located below the cooling pipe.
[0010] Preferably, the feeding assembly includes a connecting cylinder, which is fixedly connected to the top middle of the outer shell. The top of the connecting cylinder is fixedly connected to a motor. A cylindrical section is fixedly connected to the bottom middle of the connecting cylinder. The bottom of the connecting cylinder near the cylindrical section is tapered. Two feeding pipes are fixedly connected to the outside of the connecting cylinder, symmetrically arranged around the connecting cylinder. A limiting block is fixedly connected to the inner wall of the feeding pipe. An arc-shaped groove is formed at the end of the limiting block away from the connecting cylinder. Walnut oil is added into the feeding pipe and then passes through the gap between the limiting plate, the limiting block, and the middle block. The arc-shaped groove on the limiting block can cleverly intercept and guide the flowing walnut oil or gas. When oil or gas containing impurities flows through the connecting cylinder, the curvature of the arc-shaped groove can change its... The flow direction causes impurities to collide with and adhere to the curved surface under inertia, while pure oil can smoothly pass through the curved surface, achieving efficient separation of impurities and target materials and ensuring the overall processing efficiency of the equipment. A limiting plate is fixedly connected inside the feed pipe, and the limiting plate is located above the limiting block. An intermediate block is fixedly connected to the side of the limiting block near the limiting plate. There are multiple intermediate blocks, which are evenly arranged in the gap between the limiting block and the limiting plate. A circular groove is opened on the side of the intermediate block away from the limiting block. There are multiple circular grooves, which are evenly arranged on the intermediate block. A guide ring is set inside the connecting cylinder. By setting the guide ring, the oil enters from the tangential direction, so that the oil will form a stable rotating flow field inside the connecting cylinder.This rotating flow allows the oil to be distributed more evenly on the inner wall of the equipment or in the processing area, avoiding the local accumulation that may occur with traditional axial feeding. This ensures that each portion of oil fully contacts the subsequent heating and screening structures, improving the overall uniformity of the processing. Simultaneously, the centrifugal force generated by the rotation can initially separate some impurities in the oil; heavier impurities will move towards the edges under centrifugal force, facilitating the operation of subsequent screening structures such as arc blocks and improving the efficiency of impurity removal. There are two guide rings, symmetrically arranged inside the connecting cylinder. The guide rings are located at the end of the connecting cylinder near the feed pipe. A rotating shaft is located in the middle of the cylinder, with its top fixedly connected to the motor output. A spiral plate is fixedly connected to the outside of the rotating shaft, located inside the cylinder. Multiple L-shaped rotating plates are fixedly connected to the end of the rotating shaft away from the motor, rotating in a coordinated manner. The shaft is evenly distributed around the center. Filter plates are fixedly connected to the inner wall of the connecting cylinder. Baffles are fixedly connected to the inner wall of the connecting cylinder near the feed pipe. Walnut oil enters the interior of the connecting cylinder through the feed pipe, and then enters the interior of the cylinder through the filter plates. The motor is powered by an external power source. The motor drives the rotating shaft to rotate, which in turn drives the scraper to rotate through the round rod and positioning ring. This causes the scraper to scrape the outer side of the filter plate, preventing clogging. At the same time, the rotating shaft drives the spiral plate and the rotating plate to rotate, which stirs the walnut oil inside the cylinder. The baffle is a conical cylinder design, and the baffle is inclined from top to bottom, from the inner wall of the connecting cylinder to the interior of the connecting cylinder. Multiple round rods are fixedly connected to the outer side of the rotating shaft. The round rods are located above the filter plates. A positioning ring is fixedly connected to the end of the round rod away from the rotating shaft. Multiple scrapers are fixedly connected to the bottom of the positioning ring. The scrapers are in contact with the outer side of the filter plates.
[0011] Preferably, the heating component includes a base, which is fixedly connected to the bottom of the outer casing. Multiple square grooves are evenly distributed along the edge of the base. A retaining plate is located inside the square grooves. Heating wires are installed inside the base, arranged in a spiral pattern with a denser central section and sparser edges. The denser central section forms a stronger heat source in the core area where walnut oil is concentrated, rapidly increasing the central temperature and ensuring that the walnut oil in this area reaches the conditions required for plasticizer decomposition in a short time, thus improving the efficiency of heating and decomposition. The sparser edges prevent excessively high temperatures at the edges of the equipment, reducing ineffective heat loss to the outside. While ensuring the heating effect in the core area, it achieves reasonable energy allocation and conservation. At this time, through the setting of the heating wire shape, the high temperature in the middle is concentrated on the main decomposition process of walnut oil, while the relatively low and stable temperature at the edge creates a suitable environment for gas flow and subsequent filtration and adsorption, avoiding interference with the overall processing effect due to abnormal edge temperature. At the same time, the reasonable control of edge heat also reduces the risk of damage to the equipment shell due to high temperature, indirectly extending the service life of the equipment. The bottom of the base is fixedly connected to a base plate with a cross design. A spring is fixedly connected to the end of the base plate, and a pressure plate is fixedly connected to the end of the spring away from the base plate. The heating wire is located in the gap between the pressure plate and the base plate.
[0012] This invention provides a plasticizer removal device for the walnut oil production process. It has the following beneficial effects:
[0013] I. The plasticizer removal device in the walnut oil production process forms a flow channel through the cylinder, the intermediate cylinder and the outer shell. The flow channel extends the residence time of the decomposed gas in the equipment, making the heating decomposition process more thorough and avoiding the problem of plasticizer residue caused by insufficient processing time. It guides the decomposed gas to flow in an orderly manner, which not only reduces the turbulent collision of gas in the equipment and reduces energy loss, but also allows the gas to enter the outer filtration and adsorption area evenly.
[0014] Second, the plasticizer removal device in the walnut oil production process provides a directional guidance path for plasticizer gas through the flow channel, avoiding disorderly diffusion of gas during the rising process, allowing more plasticizer gas to concentrate and flow to the top area, reducing processing dead zones caused by flow dispersion. The cooling pipe and the gas guided by the flow channel form a vertical cross contact mode, increasing the contact area and contact time between the two, reducing gas bypass phenomenon, and ensuring that more plasticizer components are condensed and captured.
[0015] Third, the plasticizer removal device in the walnut oil production process can cleverly intercept and guide the flowing walnut oil or gas through the arc groove on the limiting block. When the oil or gas containing impurities flows through the connecting cylinder, the curved surface of the arc groove can change its flow direction, causing the impurities to collide with and adhere to the arc surface under the action of inertia, while the pure oil can pass smoothly along the arc surface, realizing the efficient separation of impurities and target substances and ensuring the overall processing efficiency of the equipment.
[0016] IV. The plasticizer removal device in this walnut oil production process, by setting up a guide ring, allows the oil to enter tangentially, creating a stable rotating flow field inside the connecting cylinder. This rotating flow allows the oil to be more evenly distributed on the inner wall of the equipment or in the processing area, avoiding the local accumulation phenomenon that may occur with traditional axial feeding. This ensures that each piece of oil can fully contact the subsequent heating, screening, and other processing structures, improving the overall uniformity of the processing.
[0017] V. The plasticizer removal device in this walnut oil production process uses a spiral heating wire configuration, with the wires being denser in the center and sparser at the edges. The denser heating wires in the center create a stronger heat source in the core area where the walnut oil is concentrated, rapidly increasing the temperature in the center and ensuring that the walnut oil in this area reaches the conditions required for plasticizer decomposition in a short time, thus improving the efficiency of heating and decomposition. The sparser heating wires at the edges prevent the temperature in the edge areas of the equipment from becoming too high, reducing ineffective heat loss to the outside. While ensuring the heating effect in the core area, it also achieves reasonable energy allocation and conservation. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] First embodiment, such as Figures 1 to 5 As shown, the present invention provides a technical solution: a plasticizer removal device for walnut oil production process, including a housing 3 and a bracket 1 fixedly installed at the bottom of the housing 3, with a side plate 8 fixedly connected to the top end of the bracket 1;
[0032] Heating component 2 is fixedly installed at the bottom of housing 3;
[0033] The feeding component 4 is located on the top of the housing 3, and a motor 5 is fixedly connected to the top of the feeding component 4.
[0034] The housing 3 includes an outer shell 31, which is fixedly connected to the support 1. The bottom end of the outer shell 31 is fixedly connected to the heating component 2. A cylinder 34 is fixedly connected to the middle of the inner part of the outer shell 31. The cylinder 34, the intermediate cylinder 36, and the outer shell 31 form a flow channel. When walnut oil is added to the cylinder 34, the heating component 2 at the bottom operates, making the middle part the heating and decomposition zone for walnut oil. This allows the walnut oil to be heated in the core area, ensuring that the plasticizer is fully decomposed. At the same time, the flow channel extends the residence time of the decomposed gas in the equipment, making the heating and decomposition process more thorough and avoiding plasticizer residue caused by insufficient processing time. The problem is that the gas after decomposition is guided to flow in an orderly manner, which not only reduces the turbulent collision of gas in the equipment and reduces energy loss, but also allows the gas to enter the outer filtration and adsorption area evenly. By setting a filter plate 39 between the intermediate cylinder 36 and the outer shell 31, residual plasticizers and other impurities in the flowing gas can be captured efficiently, improving the purity of the final walnut oil. The intermediate cylinder 36 is set inside the outer shell 31 and is sleeved on the outside of the cylinder 34. The inner wall of the outer shell 31 is fixedly connected to the filter plate 39. There are multiple filter plates 39, which are located in the gap between the intermediate cylinder 36 and the outer shell 31.
[0035] There are multiple side plates 8, which are evenly distributed around the housing 3. The inner side of the side plate 8 contacts the outer side of the housing 3. A support ring is provided on the top of the side plate 8, and a support rod 7 is fixedly connected to the top of the support ring. The support rod 7 is fixedly connected to the feeding assembly 4. A cooling pipe 6 is fixedly connected to one end of the housing 3 near the inside of the motor 5. During the decomposition of walnut oil plasticizer, high-temperature gas carrying plasticizer components is generated. When these gases flow upward, the cooling pipe 6 at the top can quickly cool them down, causing some easily condensable plasticizer components to condense into liquid, which is convenient for subsequent collection and processing, and improves the separation efficiency of plasticizer.
[0036] Multiple filter plates 39 are evenly arranged in the gap between the outer shell 31 and the intermediate cylinder 36. A buffer block 33 is fixedly connected to the middle of the bottom inner side of the outer shell 31, and a fixing plate 32 is fixedly connected to the bottom inner side of the outer shell 31. The fixing plate 32 and fixing ring 313 at the bottom of the outer shell 31 are connected to the bottom heating component 2. The heat provided by the heating component 2 is transferred to the fixing ring 313 and fixing plate 32 through the bottom, raising their temperature. When gas or liquid flows through, it can be reheated or kept warm, avoiding heat waste. For plasticizers that are not completely decomposed, they can be further decomposed under the action of residual heat when flowing through the heated fixing ring 313 and fixing plate 32, improving the thoroughness of plasticizer removal. At the same time, this heat conduction method allows the internal components of the equipment to be heated more efficiently. The temperature distribution is more uniform, reducing the occurrence of local low-temperature areas and ensuring the stability of the overall treatment effect. Multiple fixing plates 32 are evenly distributed around the buffer block 33. Multiple fixing rings 313 are evenly arranged on the bottom side of the inner shell 31, all located on the same horizontal plane. Multiple partition plates 35 are evenly distributed around the cylinder 34. A discharge pipe 310 is fixedly connected to the outer side of the shell 31 near the cooling pipe 6, and the discharge pipe 310 communicates with the shell 31. Filter holes 3 are formed inside the filter plate 39. 12. The filter holes 312 are hexagonal in design, and there are multiple filter holes 312 evenly distributed on the filter plate 39. Multiple clamping plates 311 are fixedly connected to the bottom of the outer shell 31, and they are evenly distributed on the bottom of the outer shell 31. A guide tube 38 is fixedly connected to the inner wall of the outer shell 31. A limiting tube 37 is fixedly connected to the top of the intermediate cylinder 36. The two ends of the limiting tube 37 are conical. The two ends of the guide tube 38 are also conical, with a larger diameter at both ends. During the decomposition of walnut oil plasticizers, high-temperature gas carrying plasticizer components is generated. The gas moves upward, and then the airflow passes sequentially through the gap between the intermediate cylinder 36 and the cylinder body 34, and between the outer shell 31 and the intermediate cylinder 36. The spacing between the filter plates 39 allows the airflow to pass through multiple filter plates 39, and finally enter the gap between the guide tube 38 and the outer shell 31 from the gap between the limiting tube 37 and the guide tube 38. The flow channel provides a directional guiding path for the plasticizer gas, avoiding disorderly diffusion of the gas during the ascent, allowing more plasticizer gas to concentrate and flow to the top area, reducing processing dead zones caused by flow dispersion. The cooling pipe 6 and the gas guided by the flow channel form a vertically intersecting contact mode, increasing the contact area and contact time between the two, reducing gas bypass phenomenon, ensuring that more plasticizer components are condensed and captured, and improving the purification efficiency of single-stage cooling. The condensate flows along the inner wall of the outer shell 31 and is discharged from the discharge pipe 310. The guide tube 38 is sleeved on the outside of the limiting tube 37.The end of the limiting cylinder 37 furthest from the intermediate cylinder 36 is fixedly connected to the inner top of the outer casing 31. A gap exists between the end of the guide cylinder 38 furthest from the inner wall of the outer casing 31 and the top of the outer casing 31. The connection point between the guide cylinder 38 and the inner wall of the outer casing 31 is located below the cooling pipe 6.
[0037] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 6 to 9As shown, the feeding assembly 4 includes a connecting cylinder 41, which is fixedly connected to the top middle of the outer shell 31. The top of the connecting cylinder 41 is fixedly connected to the motor 5. A cylinder 43 is fixedly connected to the bottom middle of the connecting cylinder 41. The bottom of the connecting cylinder 41 near the cylinder 43 is tapered. A feeding pipe 45 is fixedly connected to the outside of the connecting cylinder 41. There are two feeding pipes 45, which are symmetrically arranged with the connecting cylinder 41 as the center. A limiting block 49 is fixedly connected to the inner wall of the feeding pipe 45. An arc groove 415 is opened at the end of the limiting block 49 away from the connecting cylinder 41. Walnut oil is added into the inside of the feeding pipe 45. Then, the walnut oil passes through the gap between the limiting plate 48, the limiting block 49, and the middle block 414. The arc groove 415 on the limiting block 49 can cleverly intercept and guide the flowing walnut oil or gas. When oil or gas containing impurities flows through the connecting cylinder 41, the curved surface of the arc groove 415 can... By changing its flow direction, impurities collide with and adhere to the curved surface under inertia, while pure oil can smoothly pass through the curved surface, achieving efficient separation of impurities and target materials, and ensuring the overall processing efficiency of the equipment. A limiting plate 48 is fixedly connected inside the feed pipe 45. The limiting plate 48 is located above the limiting block 49. An intermediate block 414 is fixedly connected to the side of the limiting block 49 near the limiting plate 48. There are multiple intermediate blocks 414, which are evenly arranged in the gap between the limiting block 49 and the limiting plate 48. A circular groove 410 is opened on the side of the intermediate block 414 away from the limiting block 49. There are multiple circular grooves 410, which are evenly arranged on the intermediate block 414. A guide ring 411 is set inside the connecting cylinder 41. By setting the guide ring 411, the oil enters from the tangential direction, so that the oil will form a stable rotating flow field inside the connecting cylinder 41.This rotating flow allows the oil to be distributed more evenly on the inner wall of the equipment or in the processing area, avoiding the local accumulation that may occur with traditional axial feeding. This ensures that each portion of oil fully contacts the subsequent heating, screening, and other processing structures, improving the overall uniformity of the processing. Simultaneously, the centrifugal force generated by the rotation can initially separate some impurities in the oil; heavier impurities will move towards the edges under centrifugal force, facilitating the operation of subsequent screening structures such as arc blocks and improving the efficiency of impurity removal. There are two guide rings 411, symmetrically arranged. Inside the connecting cylinder 41, a guide ring 411 is located at one end of the connecting cylinder 41 near the feed pipe 45. A rotating shaft 42 is located in the middle of the inner part of the cylinder 43. The top of the rotating shaft 42 is fixedly connected to the output end of the motor 5. A spiral plate 44 is fixedly connected to the outer side of the rotating shaft 42, located inside the cylinder 43. A rotating plate 46 is fixedly connected to the end of the rotating shaft 42 away from the motor 5. The rotating plate 46 has an L-shaped design, and there are multiple rotating plates 46 evenly distributed around the rotating shaft 42. A filter plate 412 is fixedly connected to the inner wall of the connecting cylinder 41. A baffle 47 is fixedly connected to the inner wall of the feed pipe 45. Walnut oil enters the interior of the connecting cylinder 41 through the feed pipe 45, and then enters the interior of the cylinder 43 through the filter plate 412. The motor 5 is powered by an external power source and drives the rotating shaft 42 to rotate. The rotating shaft 42 drives the scraper 413 to rotate through the round rod 417 and the positioning ring 416, thereby scraping the outer side of the filter plate 412 to prevent the filter plate 412 from clogging. At the same time, the rotating shaft 42 drives the spiral plate 44 and the rotating plate 46 to rotate. The rotating plate 46 cleans the walnut oil inside the cylinder 34. The stirring baffle 47 is a conical cylinder design, and the inclination direction of the baffle 47 is from top to bottom, from the inner wall of the connecting cylinder 41 to the inside of the connecting cylinder 41. A round rod 417 is fixedly connected to the outside of the rotating shaft 42. There are multiple round rods 417. The round rods 417 are located above the filter plate 412. A positioning ring 416 is fixedly connected to the end of the round rod 417 away from the rotating shaft 42. A scraper 413 is fixedly connected to the bottom of the positioning ring 416. There are multiple scrapers 413. The multiple scrapers 413 are evenly distributed on the positioning ring 416. The scrapers 413 are in contact with the outside of the filter plate 412.
[0038] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 10 to 11As shown, the heating assembly 2 includes a base 21, which is fixedly connected to the bottom of the outer casing 31. Multiple square grooves 23 are evenly distributed along the edge of the base 21. A retaining plate 311 is located inside the square grooves 23. Heating wires 22 are installed inside the base 21. These heating wires are arranged in a spiral pattern, with a denser central section and sparser edges. The denser central section of the heating wires creates a stronger heat source in the core area where walnut oil is concentrated, rapidly increasing the central temperature and ensuring that the walnut oil in this area reaches the conditions required for plasticizer decomposition in a short time, thus improving the efficiency of heating and decomposition. The sparser edges of the heating wires prevent excessively high temperatures at the edges of the equipment, reducing ineffective heat loss to the outside. While ensuring the heating effect in the core area, the system achieves reasonable energy allocation and conservation. At this time, through the shape of the heating wire 22, the high temperature in the middle is concentrated on the main decomposition process of walnut oil, while the relatively low and stable temperature at the edge creates a suitable environment for gas flow and subsequent filtration and adsorption, avoiding interference with the overall processing effect due to abnormal edge temperature. At the same time, the reasonable control of edge heat also reduces the risk of damage to the equipment shell 31 due to high temperature, indirectly extending the service life of the equipment. The bottom of the base 21 is fixedly connected to the base plate 25, which has a cross design.

[0039] In use, walnut oil enters the interior of the connecting cylinder 41 through the feed pipe 45, and then enters the interior of the cylinder 43 through the filter plate 412. When the walnut oil is added to the cylinder body 34, the heating element 2 at the bottom operates, heating the walnut oil. During the decomposition of plasticizers in the walnut oil, high-temperature gas carrying plasticizer components is generated. The gas moves upward, and then the airflow passes sequentially through the gap between the intermediate cylinder 36 and the cylinder body 34, and the gap between the outer shell 31 and the intermediate cylinder 36, allowing the airflow to pass through multiple filter plates 39. Finally, it enters through the gap between the limiting cylinder 37 and the guide cylinder 38. At the interval between the guide tube 38 and the outer shell 31, the flow channel provides a directional guiding path for the plasticizer gas, avoiding disorderly diffusion of the gas during the rising process, allowing more plasticizer gas to concentrate and flow to the top area, reducing processing dead zones caused by flow dispersion. The cooling pipe 6 and the gas guided by the flow channel form a vertically intersecting contact mode, increasing the contact area and contact time between the two, reducing gas bypass phenomenon, ensuring that more plasticizer components are condensed and captured, and improving the purification efficiency of single-stage cooling. The condensate flows along the inner wall of the outer shell 31 and is discharged from the discharge pipe 310.
