Description

Technical Field

[0001] The present invention relates to the technical field of filtering devices, and in particular to a raw material processing device and method for sustainable aviation fuel. Background Art

[0002] Sustainable aviation fuel, also known as biojet fuel, is a new type of aviation fuel made from waste animal and plant oils (such as vegetable oil, animal and plant fats, waste cooking oil, etc.). Compared with traditional aviation fuel, sustainable aviation fuel has the advantage of being clean. During production, there will be a lot of scum, sediment or other impurities inside the waste animal and plant oils, which need to be filtered, and the filter cartridge needs to be continuously cleaned during the filtration process to avoid clogging of the filter holes. Most related technologies use scrapers to scrape the inner wall of the filter cartridge to avoid clogging of the filter holes.

[0003] The patent document with the authorization announcement number CN117298713B discloses a device for separating and recovering regenerated waste oil, including an integrated filter box, a connection frame connected to the top of the integrated filter box, a processing frame connected to the top of the connection frame, a plurality of liquid pipes connected between the bottom of the processing frame and the integrated filter box, a partition plate connected to the upper side of the inside of the processing frame, an automatic stirring heating cylinder connected to the top of the processing frame, the waste oil is separated and processed by a rotating centrifugal separation cylinder, the rotating scraper and the guide block rotate together, and the rotating scraper is intermittently opened and closed by an arc-shaped convex portion. When the rotating scraper is opened, the baffle blocks the impurity discharge channel, and when the rotating scraper is closed, the baffle is opened, and the rubber part scrapes impurities on the inner wall of the centrifugal separation cylinder and a small amount of waste oil into the impurity discharge channel for discharge, thereby performing impurity discharge during centrifugal separation and improving the separation and impurity removal effects.

[0004] However, when the rotating scraper in the above-mentioned equipment is opened, some impurities are easily scraped to the outside of the rotating scraper, so that when the rotating scraper is closed, these impurities cannot enter the inside of the rotating scraper and be discharged from the impurity removal channel, affecting the separation effect. In addition, when the impurities on the inner wall of the centrifugal separation cylinder are cleaned by scraping, some impurities that are difficult to pass through the filter holes are easily squeezed out of the filter holes, which causes the filtered waste oil to be contaminated again. Summary of the invention

[0022] The beneficial effects of the present invention are: 1. The present invention divides the interior of the cylinder into a pre-filter chamber and a post-filter chamber through a filtering mechanism.

[0031] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0032] like Figures 1 to 6 As shown, a raw material processing device for sustainable aviation fuel of the present invention comprises a cylinder 1, a frame 11, and a filtering mechanism and a cleaning mechanism arranged in the cylinder 1. The cylinder 1 is provided with a feed inlet 12 and a discharge port 13.

[0033] The filter mechanism includes multiple groups of filter components and a driving structure 1. The multiple groups of filter components are arranged in an array along the circumference of the cylinder 1. Each group of filter components includes two filter plates 21 and a hinge shaft 22 arranged longitudinally. The two filter plates 21 are symmetrically arranged on both sides of the hinge shaft 22 and are respectively hinged to the hinge shaft 22 through a torsion spring 1. When no force is applied, the two filter plates 21 are in a flattened state under the action of the torsion spring 1. At this time, the two filter plates 21 are in the same plane. When force is applied, the two filter plates 21 can rotate relative to the hinge shaft 22, and the torsion spring 1 is twisted to store force. The adjacent two groups of filter components are connected to each other. The components can abut against each other, and a seal is provided on the side of each filter plate 21 away from the hinge shaft 22 to ensure the sealing during abutment. By abutting against each other between multiple groups of filter components, the interior of the cylinder 1 can be divided into a pre-filter chamber 14 and a post-filter chamber 15. The pre-filter chamber 14 is a space formed by the inner sides of multiple filter plates 21, and the pre-filter chamber 14 is communicated with the feed port 12. The post-filter chamber 15 is a space between the outer side of the filter plate 21 and the inner wall of the cylinder 1, and the post-filter chamber 15 is communicated with the discharge port 13. The driving structure 1 is used to drive the multiple groups of filter components to rotate around the axis of the cylinder 1.

[0034] The cleaning mechanism includes a recoil assembly and a collecting assembly. The recoil assembly includes an adjusting rod 31 and a driving structure 2. The driving structure 2 is used to drive the hinge shaft 22 to move along the radial direction of the cylinder 1. The adjusting rod 31 is used to drive the two filter plates 21 in the same group to rotate in opposite directions around the hinge shaft 22 and arrange in a V shape during the movement of the hinge shaft 22, so that the filter assembly can switch between a flattened state and a V-shaped state. The collecting assembly includes a scraper 41 and a driving structure 3. The shape of the scraper 41 is adapted to the pre-filter chamber 14 formed by the filter plate 21 in the V-shaped state. The scraper 41 is densely covered with filter holes, and the lower end of the scraper 41 has a debris collecting groove. The driving structure 3 is used to drive the scraper 41 to move up and down.

[0035] Specifically, Figures 1 to 6As shown, in the initial state, the two filter plates 21 of the same group are in a flattened state, and the two adjacent groups of filter components are abutted against each other, dividing the interior of the cylinder 1 into a pre-filter chamber 14 and a post-filter chamber 15. The raw material to be filtered is added to the cylinder 1 from the feed port 12, and the raw material will enter the pre-filter chamber 14. At this time, the filter component is driven by the driving structure 1 to rotate around the axis of the cylinder 1, and the raw material in the pre-filter chamber 14 can pass through the filter holes on the filter plate 21 under the action of centrifugal force. Enter the post-filter chamber 15 and be discharged from the discharge port 13, and impurities in the raw material will be trapped in the pre-filter chamber 14. When there are too many impurities and the filter holes on the filter plate 21 are blocked, the hinge shaft 22 is driven by the driving structure 2 to move along the radial direction of the cylinder 1, and the filter plate 21 is driven to move. In this process, the two filter plates 21 of the same group will move in opposite directions and be arranged in a V shape under the action of the adjusting rod 31, so that the two adjacent groups of filter components remain abutted and continue to filter the raw material. With the reciprocating movement of the filter plate 21, it can The filter plate 21 is backwashed and cleaned by the raw material in the post-filter chamber 15, and the impurities blocked in the filter holes are backwashed out. After the filter plate 21 reciprocates several times, the hinge shaft 22 is driven by the driving structure 2 to move to a position close to the axis of the cylinder 1, so that the volume of the pre-filter chamber 14 is minimized. At this time, the shape of the pre-filter chamber 14 formed by the filter plate 21 is just consistent with the scraper 41. The scraper 41 is driven by the driving structure 3 to move downward, and the raw material in the pre-filter chamber 14 will flow through the filter holes on the scraper 41 to the top of the scraper 41, while the impurities in the pre-filter chamber 14 will be trapped under the scraper 41, and when the scraper 41 moves to the bottom of the cylinder 1, the impurities are intercepted between the impurity collecting trough provided at the lower end of the scraper 41 and the bottom of the cylinder 1, so as to separate the impurities from the raw material. In the process of the reciprocating movement of the filter plate 21 and the downward movement of the scraper 41, the raw material in the pre-filter chamber 14 can be continuously filtered through the filter plate 21, so that the filtering work and the cleaning work can be carried out simultaneously, thereby improving the work efficiency.

[0036] In some embodiments, the cleaning mechanism also includes a flipping assembly, which is used to drive the hinge shaft 22 to rotate around its own axis. The flipping assembly includes a gear three 51 and a rack 52. The gear three 51 is sleeved on the outside of the hinge shaft 22, and the rack 52 is arranged at the upper end of the cylinder 1 along the radial direction of the cylinder 1. During the movement of the hinge shaft 22 along the radial direction of the cylinder 1, the gear three 51 can engage with the rack 52.

[0037] After the raw material is filtered, the inside of the cylinder 1 needs to be cleaned for next use. Specifically, Figures 1 to 6As shown, water is passed into the cylinder 1 through the feed port 12, and the driving structure 2 drives the hinge shaft 22 to move along the radial direction of the cylinder 1 in a direction away from the axis of the cylinder 1, and drives the gear 3 51 arranged on the hinge shaft 22 to move synchronously. During this process, the two filter plates 21 of the same group will switch from the V-shaped state to the flattened state under the action of the torsion spring 1. When the filter plate 21 is in the flattened state, the hinge shaft 22 is driven to continue to move through the driving structure 2, and the two adjacent groups of filter components will move away from each other. During this process, the gear 3 51 will mesh with the rack 52, so that the gear 3 51 rotates, and drives the hinge shaft 22 to rotate, thereby driving the two filter plates 21 to rotate with the hinge shaft 22, so that the filter plates 21 face the cylinder 1. One side of the axis rotates to the outside, and at the same time, the filter plate 21 rotates to the inside toward one side of the side wall of the cylinder 1. In this process, the scraper 41 is driven to move upward by the driving structure three to expose the impurities intercepted in the collecting tank again, and then the filter component is driven to rotate around the axis of the cylinder 1 by the driving structure one. At this time, under the action of centrifugal force, the impurities exposed from the collecting tank can move to the side wall of the cylinder 1 through the gap between the two adjacent groups of filter components, and be discharged from the discharge port 13 with the water flow. In addition, due to the flipping of the filter plate 21, the side of the filter plate 21 with impurities attached can be turned to the inner wall of the cylinder 1, so that the attached impurities are easier to fall off under the action of centrifugal force and are discharged synchronously with the water flow, thereby improving the cleaning efficiency of the filter plate 21.

[0038] In some embodiments, a driving structure includes a rotating plate 23 rotatably disposed in the cylinder 1, and a driving member 24 for driving the rotating plate 23 to rotate. The number of rotating plates 23 is two, and they are respectively disposed at the upper and lower ends of the cylinder 1. A rod is connected between the two rotating plates 23 to ensure that the two can rotate synchronously. A plurality of sliding grooves 231 are opened on the rotating plate 23 along its circumference, and each sliding groove 231 is arranged along the radial direction of the rotating plate 23. A slider 25 is slidably disposed in the sliding groove 231, and the end of each hinge shaft 22 extends into the corresponding slider 25, and is rotatably connected to the slider 25 through a torsion spring 2.

[0039] Specifically, Figures 2 to 6 As shown, the starting driving member 24 drives the rotating plate 23 to rotate, which can drive the slider 25 sliding in the slide groove 231 to rotate, and drive the hinge shaft 22 connected to the slider 25 to rotate, so that multiple groups of filter components rotate synchronously around the axis of the cylinder 1, so that under the action of centrifugal force, the raw materials in the pre-filter chamber 14 flow into the post-filter chamber 15 through the filter plate 21 to filter the raw materials. By arranging a torsion spring 2 between the hinge shaft 22 and the slider 25, the position state of the hinge shaft 22 and the filter plate 21 can be guaranteed, so as to prevent the filter plate 21 from being impacted by the raw materials and driving the hinge shaft 22 to rotate relative to the slider 25, thereby destroying the abutment between the two adjacent groups of filter components and affecting the isolation between the pre-filter chamber 14 and the post-filter chamber 15.

[0040] In some embodiments, driving structure 2 includes a lifting plate 32, a driving member 33 and a plurality of connecting rods 34. A fixed rod 16 is connected between the upper end of the cylinder 1 and the frame 11. The fixed rod 16 is longitudinally arranged at the axis of the cylinder 1. The lifting plate 32 is longitudinally slidably sleeved on the outside of the fixed rod 16. The driving member 33 is arranged on the frame 11. The driving member 33 is set as a cylinder. The output end of the cylinder is connected to the lifting plate 32. Multiple connecting rods 34 are respectively arranged corresponding to multiple hinge shafts 22. One end of the connecting rod 34 is hinged to the lower end of the lifting plate 32, and the other end is hinged to the slider 25 on the corresponding hinge shaft 22.

[0041] Specifically, Figures 1 to 6 As shown, when the second driving member 33 is started to drive the lifting plate 32 to move downward, the slider 25 can be pushed to move along the slide groove 231 in the direction away from the axis of the cylinder 1 under the action of the connecting rod 34, and the hinge shaft 22 connected to the rotation of the slider 25 can be driven to move synchronously, and the filter plate 21 can be driven to move at the same time. When the second driving member 33 is started to drive the lifting plate 32 to move upward, the slider 25 can be pulled to move in the direction close to the axis of the cylinder 1 under the action of the connecting rod 34, and the filter plate 21 can be driven to move. Through the reciprocating movement of the filter plate 21, the raw material in the post-filter chamber 15 can backwash the filter plate 21.

[0042] In some embodiments, there are multiple adjusting rods 31, and they are arranged in groups of two corresponding to the multiple slide grooves 231. The two adjusting rods 31 in the same group are symmetrically arranged on both sides of the slide groove 231. The adjusting rod 31 is horizontally arranged on the rotating plate 23. The end of the adjusting rod 31 facing the axis of the cylinder 1 is defined as the inner end, and the other end is defined as the outer end. Each adjusting rod 31 is tilted from the outer end to the inner end toward the direction close to the slide groove 231.

[0043] Specifically, Figures 2 to 6As shown, in the initial state, the two filter plates 21 of the same group are in a flattened state, and at this time, the two adjacent groups of filter components are abutted against each other, dividing the interior of the cylinder 1 into a pre-filter chamber 14 and a post-filter chamber 15. At this time, the volume of the pre-filter chamber 14 is the largest, and the volume of the post-filter chamber 15 is the smallest. When the hinge shaft 22 is driven by the driving structure 2 to move in the direction close to the axis of the cylinder 1, the filter plate 21 will be driven to move synchronously. During this process, the side of the filter plate 21 away from the hinge shaft 22 will contact the adjusting rod 31 on the corresponding side. Since the adjusting rod 31 is tilted, the filter plate 21 will rotate around the hinge shaft 22 while the hinge shaft 22 moves, so that the two filter plates 21 are arranged in a V shape, and the two adjacent groups of filter components remain abutted until the hinge shaft 22 moves. When the hinge shaft 22 is driven by the driving structure 2 to move in the direction away from the axis of the cylinder 1, the filter plate 21 will be driven to move. During this process, the filter plate 21 will be reversed around the hinge shaft 22 under the action of the corresponding torsion spring 1, so that the two filter plates 21 in the same group are in a flattened state again. At this time, the volume of the pre-filter chamber 14 is restored to the maximum state again, and the post-filter chamber 15 is restored to the minimum state. When the filter plate 21 is blocked, the discharge port 13 is closed, and the raw material in the post-filter chamber 15 can flow by changing the size of the post-filter chamber 15, so as to backwash the filter plate 21.

[0044] In some embodiments, the driving structure three includes a screw 42, a driving member three 43, a gear one 44 and a gear two 45. The screw 42 is longitudinally arranged inside the cylinder 1, and the gear one 44 and the gear two 45 are both rotatably arranged on the frame 11. The driving member three 43 is arranged on the frame 11, and the driving member three 43 is set as a motor. The output end of the motor is connected to the gear one 44, which is used to drive the gear one 44 to rotate. The outer side of the gear two 45 is meshed with the gear one 44, and the inner side of the gear two 45 is threadedly matched with the screw 42. The scraper 41 is arranged at the lower end of the screw 42.

[0045] Specifically, Figures 1 to 3 , Figure 6As shown, in the process of driving the hinge shaft 22 to move along the radial direction of the cylinder 1 by the driving structure 2, when the hinge shaft 22 is at the end of the slide groove 231 close to the axis of the cylinder 1, the volume of the pre-filter chamber 14 is the smallest, and the shape of the pre-filter chamber 14 is consistent with the shape of the scraper 41. At this time, the driving member 3 43 is started to drive the gear 1 44 to rotate, and the gear 2 45 can be driven to rotate through the meshing transmission between the gear 1 44 and the gear 2 45, and the gear 2 45 can be driven to rotate through the threaded cooperation between the gear 2 45 and the screw 42. The screw 42 moves up and down. When the screw 42 moves downward, it can drive the scraper 41 arranged at the lower end of the screw 42 to move synchronously. During this process, the raw material below the scraper 41 will flow into the top of the scraper 41 through the filter holes arranged on the scraper 41, and the impurities below the scraper 41 will be retained under the scraper 41. When the scraper 41 moves to the bottom of the barrel 1, the impurities are intercepted between the impurity collecting trough arranged at the lower end of the scraper 41 and the bottom of the barrel 1, thereby realizing the separation of the raw material and the impurities.

[0046] In some embodiments, the feed port 12 includes a feed port 121 disposed at the center of the scraper 41, and a feed port 2 122 disposed on the side wall of the screw 42. The interior of the screw 42 is hollow and open at both ends. When the scraper 41 is located at the top of the barrel 1, the interior of the screw 42 is communicated with the pre-filter chamber 14 through the feed port 121. When the scraper 41 is at the bottom of the barrel 1, the interior of the screw 42 is communicated with the pre-filter chamber 14 through the feed port 2 122.

[0047] Specifically, Figure 2 , Figure 3 and Figure 6 As shown, when the scraper 41 is located at the top of the barrel 1, the raw material will be discharged from the lower end of the screw 42, and flow into the pre-filter chamber 14 through the feed port 121 provided on the scraper 41 for filtration; when the scraper 41 moves to the bottom of the barrel 1 under the action of the driving structure 3, the feed port 121 is closed by the bottom of the barrel 1, and the raw material will be discharged from the feed port 2 122 provided on the side wall of the screw 42, and flow into the pre-filter chamber 14 for filtration.

[0048] In some embodiments, a baffle 46 capable of closing the feed port 121 is provided at the feed port 121, and the upper end of the baffle 46 is connected to the screw 42 through an elastic member 47, and the elastic member 47 is configured as a spring.

[0049] Specifically, Figure 2 , Figure 3 and Figure 6As shown, when the scraper 41 is located at the top of the barrel 1, the raw material will impact the baffle 46 at the feed port 121 during the process of being discharged from the lower end of the screw 42, so that the baffle 46 is forced to move downward, and the elastic member 47 is stretched to store force. With the movement of the baffle 46, the feed port 121 is opened. At this time, the raw material can flow from the feed port 121 into the pre-filter chamber 14 for filtration. After the raw material is added, the baffle 46 loses the force of the raw material and moves upward under the action of the elastic member 47 to reset, and the feed port 121 is closed again to prevent impurities from entering the barrel 1 from the feed port 121 and affecting the filtration of the raw material. The scraper is driven by the driving structure 3 When the plate 41 moves downward, the raw material below the scraper 41 flows to the top of the scraper 41 through the filter holes provided on the scraper 41, and the impurities are intercepted below the scraper 41. During this process, the baffle 46 maintains the closure of the feed port 121 under the action of the elastic member 47, preventing the impurities below the scraper 41 from moving directly from the feed port 121 to the top of the scraper 41, thereby affecting the collection of impurities in the pre-filter chamber 14. During the downward movement of the scraper 41, the raw material will flow from the feed port 122 provided on the side wall of the screw 42 into the pre-filter chamber 14 for filtration; when the scraper 41 moves to the bottom of the barrel 1, the raw material will continue to flow from the feed port 122 into the pre-filter chamber 14 for filtration.

[0050] like Figures 1 to 6 As shown, the present invention also provides a method for processing a raw material of sustainable aviation fuel using the above-mentioned raw material processing device, which specifically comprises the following steps: S1: Feeding: adding the raw material to be filtered from the feed port 12 into the pre-filter chamber 14 provided inside the cylinder 1; S2: Filtration: The filter plate 21 is driven to rotate around the axis of the cylinder 1 by the driving structure 1, so that the raw materials in the pre-filter chamber 14 can enter the post-filter chamber 15 after being filtered by the filter plate 21 under the action of centrifugal force, and are discharged from the discharge port 13, while the impurities are intercepted in the pre-filter chamber 14; S3: Backwash cleaning: When the filter plate 21 is blocked, the discharge port 13 is closed, and the hinge shaft 22 is driven by the second driving structure to reciprocate along the radial direction of the cylinder 1, and the filter plate 21 is driven to reciprocate, so that in this process, the filter plate 21 is backwashed by the raw materials in the post-filter cavity 15 to clean out the impurities blocked in the filter holes; S4: Collection and cleaning: When the filter plate 21 moves to a position close to the axis of the cylinder 1, the drive structure 3 drives the scraper 41 to move downward to collect and clean the impurities intercepted in the pre-filter chamber 14, thereby separating the impurities from the raw materials; S5: Continue filtering: After the filter plate 21 is cleaned, the discharge port 13 is opened, and the raw material in the pre-filter chamber 14 is continuously filtered through the filter plate 21 until the filtering is completed.

[0051] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
