Description

Technical Field

[0001] The invention relates to the technical field of waste engine oil regeneration, in particular to a multi-stage catalytic distillation waste engine oil regeneration device. Background Art

[0002] Waste oil refers to oil that has been contaminated with impurities such as water, dust, other miscellaneous oils, and metal powder from wear and tear during use, resulting in a darkening and increased viscosity. It also refers to oil that has gradually deteriorated, producing organic acids, colloids, and asphalt-like substances. Recycling waste oil involves removing impurities through methods such as sedimentation, distillation, pickling, alkali washing, and filtration.

[0003] The patent with publication number CN116983689A discloses a high-efficiency waste oil regeneration and recycling tower, including a tower body and a filter part, wherein the filter part includes: a hollow threaded rod: which is movably connected to the inner wall of a through hole opened at the top of the tower body, and a flange is welded to the outer wall of the top of the hollow threaded rod; a mounting ring: which is fixed to the inner wall of the circumference of the tower body; a movable seat: which is connected to the outer wall of the circumference of the hollow threaded rod by a thread; a connecting rod: which is fixed to the outer wall of the movable seat, and the connecting rod is movably connected to the inner wall of the through hole opened on the surface of the mounting ring; a filter screen: which is fixed to the outer wall of the bottom of the connecting rod; a hollow cylinder: which is fixed to the outer wall of the bottom of the hollow threaded rod by a pin, and the hollow cylinder and the hollow threaded rod are connected; a T-rod: which is movably connected to the inner wall of the through hole opened at the bottom of the hollow cylinder; a scraper frame: which is fixed to the outer wall of the bottom of the T-rod by a pin, and a suction hole is opened on the surface of the scraper frame. The provision of a filter screen allows for effective filtration of impurities contained in the atomized engine oil. The provision of a drive motor allows for the rotation of the hollow threaded rod, allowing the filter screen to be vertically moved downward under the guiding and limiting action of the connecting rod and the mounting ring, allowing the filter screen to exert pressure on the surface of the scraper frame, thereby facilitating the use of the scraper frame to clean impurities attached to the filter screen surface. The provision of a flange plate allows for connection to an extraction mechanism, such as an air pump, allowing impurities scraped off by the scraper frame to be introduced into the T-shaped rod and the hollow cylinder through the suction hole, and ultimately to be absorbed by the extraction mechanism through the hollow threaded rod. The provision of a corresponding collection device on the extraction mechanism allows for the collection of impurities.

[0004] The heated atomized oil and impurities are separated. The filter provided in the above technical solution may cause the oil mist to accumulate on the filter and re-mix with the impurities. In addition, the pass rate of the filter decreases with the increase of usage time, which delays the regeneration process. The impurities are collected through the suction holes by an external extraction mechanism, which will also suck out the oil mist, resulting in a decrease in the regeneration efficiency. Therefore, the generation of impurities is inevitable and needs to be circumvented from the perspective of impurity generation. Therefore, a multi-stage catalytic distillation waste oil regeneration device is urgently needed to solve the above problems. Summary of the Invention

A discharge disc 204 adapted to the discharge cylinder 201 is fixedly wound around the column 203, and the surface of the discharge disc 204 is provided with mesh holes.

[0080] One side of the upper end of the discharge cylinder 201 is fixedly connected to a discharge pipe 205;

[0081] The other side of the lower end of the discharge tube 201 is fixedly connected to an inlet box 206 connected to the docking port 108 . The lower inner wall of the inlet box 206 is fixedly connected to an inclined platform 207 for guiding impurities into the bottom of the discharge tube 201 .

[0082] The working principle of the present invention is as follows:

[0083] The waste oil is introduced from the inlet pipe 105 into the sedimentation tank 101 for precipitation to reduce the solid impurities therein, and then introduced into the regeneration chamber 303 at the bottom through the first outlet pipe 106 and the first oil pipe 304 for catalytic distillation. The insulation cylinder 301 is vertically divided by the partition plate 302 and the regeneration chamber 303, and each regeneration chamber 303 is heated and catalyzed separately to achieve axial temperature gradient control, thereby reducing the generation of impurities during the regeneration process, reducing impurities from the source, and improving the purity of the regenerated oil.

[0084] The impurities in the waste oil entering the sedimentation tank 101 from the inlet pipe 105 do not need to be settled at the bottom of the sedimentation tank 101. They only need to settle to the upper surface of the sedimentation platform 102, and slide along its upper surface to the upper surface of the sedimentation plate 104, continue to slide along the sedimentation plate 104 through the opening 108 and fall into the inlet box 206 for aggregation, shortening the sedimentation path of the impurities and improving the separation speed of the impurities.

[0085] A settling platform 102 with an inclined upper surface is set in the sedimentation tank 101, and a settling tank 103 is opened on the upper surface of the settling platform 102, so that the space on the upper surface of the settling platform 102 is divided into multiple miniature settling units, so that the impurities in the waste oil entering from the inlet pipe 105 are simultaneously settled from the settling tank 103, thereby greatly increasing the contact area between the waste oil and the settling platform 102, and further improving the impurity separation speed.

[0086] The waste oil flows along the upper surface of the settling platform 102 and the settling plate 104, which causes little disturbance to the oil, and most of the impurities remain in the inlet box 206, thereby maintaining the laminar flow state of the oil, preventing the settled impurities from being re-rolled up, and reducing the waste of sedimentation resources.

[0087] By setting a settling plate 104 with a mesh opening opposite the settling platform 102, impurities in the waste oil can be guided to the lower side of the settling platform 102 through the settling plate 104, and fall into the inlet box 206 through the opening 108 for accumulation, while the waste oil can penetrate into the other side of the settling plate 104, promoting sedimentation and oil separation and guiding, thereby improving the sedimentation quality.

[0088] The impurities are further guided to the bottom of the discharge tube 201 by the inclined platform 207 provided in the inlet box 206. When impurities accumulate in the inlet box 206, the discharge disc 204 is driven by the starting motor 202 to discharge the impurities. The mesh holes provided on the surface of the discharge disc 204 can effectively filter the oil, thereby automatically guiding the discharge of impurities. No manual cleaning or shutdown for cleaning is required, thus realizing continuous sedimentation operation and improving sedimentation efficiency.

[0089] The first outlet pipe 106 is connected to the bottom of the sedimentation tank 101, and the second outlet pipe 107 is connected to the sedimentation plate 104, so that the oil filtered by the sedimentation plate 104 and the clear oil retained in the upper layer can be discharged through the first outlet pipe 106 and the second outlet pipe 107 respectively, thereby achieving rapid and sufficient discharge of the oil, improving the discharge speed of the oil, and helping to accelerate the regeneration of waste oil.

[0090] The outside air is introduced into the insulation mechanism 3 through the air pump 401. The fan blades 406 in the rotating tube 405 are disturbed by the high-speed airflow and then rotate with the flow tube 403 as the axis, thereby driving the catalytic mechanism 5 wrapped around the inner rod 407 to rotate, so that the oil and gas inside the regeneration chamber 303 are fully in contact with the catalyst 503, thereby improving the catalytic reaction rate.

[0091] When the inner rod 407 drives the catalytic mechanism 5 to stir in the regeneration chamber 303 , the catalytic mechanism 5 can also stir the oil and gas synchronously, thereby making the oil and gas in the regeneration chamber 303 evenly mixed and heated, thereby improving the distillation quality.

[0092] On the one hand, the catalytic mechanism 5 can be replaced regularly through the replacement port 306 opened on the regeneration chamber 303. On the other hand, the catalyst 503 is movably sleeved in the catalytic chamber 501. When the upper part of the catalyst 503 comes into contact with the oil and gas, it can also rotate with the catalytic chamber 501 as the axis, thereby causing the scraper 504 to scrape the surface of the catalyst 503 to remove the carbon deposits generated on the surface of the catalyst 503, thereby extending the service life of the catalyst 503.

[0093] The gas introduced into the circulation pipe 403 by the air pump 401 is heated when passing through the regeneration chamber 303. Therefore, after being discharged through the exhaust pipe 404, the residual heat can be used to preheat the raw materials or the engine, thereby improving energy conservation and environmental protection.

[0094] The hot air generated by the heating furnace 602 is introduced through the heat pipe 601 so that the regeneration chamber 303 is evenly heated. On the one hand, the heat pipe 601 on the side away from the regeneration chamber 303 is insulated by the insulation sleeve 603 connected to its outer cover. On the other hand, the blocking piece 604 inserted into the heat pipe 601 can gather the hot air to the side close to the regeneration chamber 303 and disturb the movement of the hot air through the spoilers 605 arranged at equal intervals, thereby further improving the heat transfer efficiency and increasing the heat utilization rate.

[0095] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
