Description

Technical Field

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

[0002] Sustainable aviation fuel, also known as bio-jet fuel, is a new type of aviation fuel made from waste oils and fats of animals and plants (such as vegetable oils, animal and vegetable fats, waste cooking oils, etc.). Compared with traditional aviation fuel, sustainable aviation fuel has outstanding cleanliness advantages. During production, there are many floating residues, sediments or other impurities in the waste oils and fats of animals and plants, which need to be filtered. And during the filtering process, the filter cylinder needs to be continuously cleaned to avoid clogging of the filter holes. In related technologies, a scraper is mostly used to scrape the inner wall of the filter cylinder to avoid clogging of the filter holes.

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

[0004] However, during the opening process of the rotating scraper in the above device, it is easy to scrape some impurities to the outside of the rotating scraper, so that when the rotating scraper is closed, this part of the impurities cannot enter the inside of the rotating scraper and be discharged from the impurity discharge channel, affecting the separation effect. In addition, when using the scraping method to clean the impurities on the inner wall of the centrifugal separation cylinder, it is easy to squeeze out some impurities that are difficult to pass through the filter holes, instead re-polluting the filtered waste oil. Summary of the Invention

In addition, when using the scraping method to clean the impurities on the inner wall of the centrifugal separation cylinder, it is easy to squeeze out some impurities that are difficult to pass through the filter holes, instead re-polluting the filtered waste oil.

[0006] In a first aspect, a raw material processing device for sustainable aviation fuel according to the present invention includes a cylinder body and a frame body, and further includes a filtering mechanism and a cleaning mechanism disposed inside the cylinder body;

The scraper is densely provided with filter holes, and a impurity collection groove is provided at the lower end of the scraper. The driving structure three is used to drive the scraper to move up and down.

[0009] When the filter plate is blocked, the backwashing component is used to make the filter plate move reciprocally, so as to backwash and clean the filter plate with the raw material in the post-filter chamber, and wash out the impurities blocked in the filter holes. Then, the collection component is used to collect the impurities in the impurity collection groove to ensure the separation effect.

[0010] Preferably, the cleaning mechanism further includes a flipping component. The flipping component is used to drive the hinge shaft to rotate around its own axis. The flipping component includes a third gear and a rack. The third gear is sleeved outside the hinge shaft, and the rack is arranged at the upper end of the cylinder body along the radial direction of the cylinder body. During the movement of the hinge shaft along the radial direction of the cylinder body, the third gear can be engaged with the rack.

[0011] The flipping component can be used to make the hinge shaft rotate around its own axis, turning the side of the filter plate attached with impurities towards the inner wall of the cylinder body, so that the attached impurities are more likely to fall under the action of centrifugal force, improving the cleaning efficiency of the filter plate.

[0012] Preferably, the driving structure one includes a rotating plate rotatably disposed inside the cylinder body and a first driving member for driving the rotating plate to rotate. A plurality of sliding grooves are formed along the circumferential direction of the rotating plate. Each sliding groove is arranged along the radial direction of the rotating plate.

The end of each hinge shaft extends into the corresponding sliding block and is rotatably connected to the sliding block through a second torsion spring.

[0013] Preferably, the second driving structure includes a lifting plate, a second driving member, and a plurality of connecting rods. A fixing rod is connected between the upper end of the cylinder body and the frame body. The fixing rod is longitudinally arranged at the axis of the cylinder body. The lifting plate is longitudinally and slidably sleeved outside the fixing rod. The second driving member is arranged on the frame body, and its output end is connected to the lifting plate for driving the lifting plate to move up and down. The plurality of connecting rods are respectively arranged corresponding to the plurality of hinge shafts. One end of the connecting rod is hinged to the lower end of the lifting plate, and the other end is hinged to the slider on the corresponding hinge shaft.

[0014] Preferably, a plurality of adjusting rods are provided and are arranged in pairs corresponding to the plurality of chutes. The two adjusting rods in the same group are symmetrically arranged on both sides of the chute. The adjusting rods are horizontally arranged on the rotating plate. Define the end of the adjusting rod facing the axis of the cylinder body as the inner end and the other end as the outer end. Each adjusting rod is inclined from the outer end to the inner end towards the chute.

[0015] Preferably, the third driving structure includes a screw rod, a third driving member, a first gear, and a second gear. The screw rod is longitudinally arranged inside the cylinder body. The first gear and the second gear are both rotatably arranged on the frame body. The third driving member is arranged on the frame body, and its output end is connected to the first gear. The outer side of the second gear is meshed and connected with the first gear, and the inner side of the second gear is in threaded cooperation with the screw rod. A scraper is arranged at the lower end of the screw rod.

[0016] Preferably, a feed inlet and a discharge outlet are provided on the cylinder body. The feed inlet includes a first feed inlet arranged at the center of the scraper and a second feed inlet arranged on the side wall of the screw rod. The inside of the screw rod is hollow and open at both ends. When the scraper is at the uppermost position of the cylinder body, the inside of the screw rod communicates with the pre-filter chamber through the first feed inlet. When the scraper is at the lowermost position of the cylinder body, the inside of the screw rod communicates with the pre-filter chamber through the second feed inlet.

[0017] By providing the first feed inlet and the second feed inlet, it can ensure the smooth addition of raw materials when the scraper is in different positions or during the movement of the scraper.

[0018] Preferably, a baffle is provided at the first feed inlet to close the first feed inlet. The upper end of the baffle is connected to the screw rod through an elastic member.

[0019] Prevent impurities located below the scraper from directly flowing above the scraper through the first feed inlet, which affects the collection effect of impurities.

[0020] Preferably, a sealing member is provided on the side of each filter plate away from the hinge shaft.

[0021] Ensure the sealing performance of the abutment between adjacent two groups of filtering components, and prevent the raw materials in the pre-filter chamber from flowing directly into the post-filter chamber without being filtered, which affects the filtering effect.

[0022] In a second aspect, a method for processing raw materials for sustainable aviation fuel according to the present invention uses the above-mentioned device for processing raw materials for sustainable aviation fuel, and includes the following steps:

[0023] S1: Feeding: The cylinder is provided with a feeding port and a discharging port, and the raw material to be filtered is added into the pre-filter cavity arranged inside the cylinder through the feeding port;

[0024] S2: Filtration: Drive Structure 1 drives the filter plate to rotate around the axis of the cylinder. During this process, the raw material in the pre-filter cavity can enter the post-filter cavity after being filtered by the filter plate and is discharged from the discharging port, while the impurities are intercepted in the pre-filter cavity;

[0025] S3: Backwashing and Cleaning: When the filter plate is blocked, close the discharging port, drive the hinge shaft to reciprocate along the radial direction of the cylinder through Drive Structure 2, and drive the filter plate to reciprocate, so as to backwash and clean the filter plate with the raw material in the post-filter cavity;

[0026] S4: Collection and Cleaning: When the filter plate moves to a position close to the axis of the cylinder, drive the scraper to move downward through Drive Structure 3, and collect the impurities intercepted in the pre-filter cavity into the impurity collection groove at the lower end of the scraper;

[0027] S5: Continue Filtration: After cleaning the filter plate, open the discharging port, and continue to filter the raw material in the pre-filter cavity through the filter plate.

[0028] The raw material is filtered by the filtration mechanism. When the filter plate is blocked, the filter plate is backwashed and cleaned by the backwashing component, and the washed-out impurities are collected by the collection component to ensure the separation effect.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The present invention divides the interior of the cylinder into a pre-filter cavity and a post-filter cavity through the filtration mechanism. Under the action of centrifugal force, the raw material in the pre-filter cavity enters the post-filter cavity after being filtered by the filter plate, while the impurities are intercepted in the pre-filter cavity. When the filter plate is blocked, the filter plate reciprocates through the backwashing component, so as to backwash and clean the filter plate with the raw material in the post-filter cavity, and wash out the impurities blocked in the filter holes. Then, the impurities are collected in the impurity collection groove by the collection component to ensure the separation effect.

[0031] 2. The present invention rotates the hinge shaft through the flipping component and drives the filter plate to rotate, turning the side of the filter plate with attached impurities towards the inner wall of the cylinder, making the attached impurities more likely to fall off under the action of centrifugal force and improving the cleaning efficiency.

Detailed implementation manners

[0040] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0041] As Figures 1 to 6 shown, a raw material processing device for sustainable aviation fuel of the present invention includes a cylinder body 1, a frame body 11, a filter mechanism and a cleaning mechanism provided in the cylinder body 1, and a feed inlet 12 and a discharge outlet 13 are provided on the cylinder body 1.

[0042] The filtering mechanism includes multiple groups of filtering components and a driving structure one. The multiple groups of filtering components are arranged in a circumferential array along the cylinder body 1. Each group of filtering components includes two longitudinally arranged filter plates 21 and a hinge shaft 22. 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 first torsion spring. When not under force, the two filter plates 21 are in a flattened state under the action of the first torsion spring. At this time, the two filter plates 21 are in the same plane. When under force, both filter plates 21 can rotate relative to the hinge shaft 22, causing the first torsion spring to twist and store energy. Adjacent groups of filtering components can abut against each other, and a sealing member is provided on the side of each filter plate 21 away from the hinge shaft 22 to ensure the sealing performance during abutment. By the mutual abutment of multiple groups of filtering components, the interior of the cylinder body 1 can be divided into a pre-filter chamber 14 and a post-filter chamber 15. The pre-filter chamber 14 is the space enclosed by the inner sides of multiple filter plates 21, and the pre-filter chamber 14 communicates with the feed inlet 12. The post-filter chamber 15 is the space between the outer sides of the filter plates 21 and the inner wall of the cylinder body 1, and the post-filter chamber 15 communicates with the discharge outlet 13. The driving structure one is used to drive multiple groups of filtering components to rotate around the axis of the cylinder body 1.

[0043] The cleaning mechanism includes a backwashing component and a collection component. The backwashing component includes an adjusting rod 31 and a driving structure two. The driving structure two is used to drive the hinge shaft 22 to move radially along the cylinder body 1. The adjusting rod 31 is used to drive the two filter plates 21 of the same group to rotate in opposite directions around the hinge shaft 22 and be arranged in a V-shaped layout during the movement of the hinge shaft 22, so that the filtering component can be switched between the flattened state and the V-shaped state. The collection component includes a scraping plate 41 and a driving structure three. The shape of the scraping plate 41 is adapted to the pre-filter chamber 14 enclosed by the filter plates 21 in the V-shaped state. The scraping plate 41 is densely provided with filter holes, and the lower end of the scraping plate 41 has a debris collection groove. The driving structure three is used to drive the scraping plate 41 to move up and down.

[0044] Specifically, as Figures 1 to 6As shown, in the initial state, the two filter plates 21 in the same group are in a flattened state, and the adjacent two groups of filtering components are in contact with 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 driving structure one drives the filtering component to rotate around the axis of the cylinder 1. Under the action of centrifugal force, the raw material in the pre-filter chamber 14 can pass through the filter holes on the filter plate 21 and enter the post-filter chamber 15, and be discharged from the discharge port 13, while the impurities in the raw material will be retained in the pre-filter chamber 14. When there are more impurities and the filter holes on the filter plate 21 are blocked, the driving structure two drives the hinge shaft 22 to move radially along the cylinder 1 and drives the filter plate 21 to move. During this process, the two filter plates 21 in the same group will move in the opposite direction and be arranged in a V shape under the action of the adjusting rod 31, so that the adjacent two groups of filtering components remain in contact and continue to filter the raw material. As the filter plate 21 reciprocates, the raw material in the post-filter chamber 15 can be used to backwash and clean the filter plate 21, and the impurities blocked in the filter holes are backwashed out. After the filter plate 21 reciprocates several times, the driving structure two drives the hinge shaft 22 to move to a position close to the axis of the cylinder 1, so that the volume of the pre-filter chamber 14 is the minimum. At this time, the shape of the pre-filter chamber 14 formed by the filter plate 21 is just the same as that of the scraper 41. The driving structure three drives the scraper 41 to move downward, and the raw material in the pre-filter chamber 14 will flow above the scraper 41 through the filter holes on the scraper 41, while the impurities in the pre-filter chamber 14 will be retained below the scraper 41. When the scraper 41 moves to the bottom of the cylinder 1, the impurities are intercepted between the impurity collection groove provided at the lower end of the scraper 41 and the bottom of the cylinder 1, realizing the separation of the impurities and the raw material. During 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 continue to be filtered through the filter plate 21, so that the filtering work and the cleaning work can be carried out simultaneously, improving the work efficiency.

[0045] In some embodiments, the cleaning mechanism further includes a flipping assembly for driving the hinge shaft 22 to rotate around its own axis. The flipping assembly includes a third gear 51 and a rack 52. The third gear 51 is sleeved outside the hinge shaft 22, and the rack 52 is arranged radially along the cylinder 1 at the upper end of the cylinder 1. During the process of the hinge shaft 22 moving radially along the cylinder 1, the third gear 51 can be engaged with the rack 52.

[0046] After the filtration of the raw material is completed, it is necessary to clean the interior of the cylinder 1 for the next use. Specifically, as Figures 1 to 6As shown in the figure, water is introduced into the cylinder body 1 through the feed port 12. The driving structure II drives the hinge shaft 22 to move radially away from the axis of the cylinder body 1, and drives the third gear 51 provided on the hinge shaft 22 to move synchronously. During this process, the two filter plates 21 in the same group will be switched from the V-shaped state to the flattened state under the action of the first torsion spring. When the filter plate 21 is in the flattened state, the driving structure II drives the hinge shaft 22 to continue to move, and the adjacent two groups of filtering components will move away from each other. During this process, the third gear 51 will engage with the rack 52, causing the third gear 51 to rotate, and driving the hinge shaft 22 to rotate, thereby driving the two filter plates 21 to rotate with the hinge shaft 22, so that the side of the filter plate 21 facing the axis of the cylinder body 1 rotates to the outside, and at the same time, the side of the filter plate 21 facing the side wall of the cylinder body 1 rotates to the inside. During this process, the driving structure III drives the scraper 41 to move upward, exposing the impurities intercepted in the impurity collection groove again. Then, the driving structure I drives the filtering component to rotate around the axis of the cylinder body 1. At this time, under the action of centrifugal force, the impurities exposed from the impurity collection groove can move to the side wall of the cylinder body 1 through the gap between the adjacent two groups of filtering components and be discharged from the discharge port 13 along 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 towards the inner wall of the cylinder body 1, making the attached impurities more likely to fall under the action of centrifugal force and be discharged synchronously with the water flow, improving the cleaning efficiency of the filter plate 21.

[0047] In some embodiments, the driving structure I includes a rotating plate 23 rotatably provided in the cylinder body 1 and a driving member I 24 for driving the rotating plate 23 to rotate. The rotating plate 23 is provided in two and is respectively provided at the upper and lower ends of the cylinder body 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 formed in the rotating plate 23 along its circumferential direction, and each sliding groove 231 is arranged along the radial direction of the rotating plate 23. A slider 25 is slidably provided in the sliding groove 231. The end of each hinge shaft 22 extends into the corresponding slider 25 and is rotatably connected to the slider 25 through a second torsion spring.

[0048] Specifically, as Figures 2 to 6 shown, starting the driving member I 24 to drive the rotating plate 23 to rotate can drive the slider 25 slidably provided in the sliding groove 231 to rotate, and drive the hinge shaft 22 rotatably connected to the slider 25 to rotate, so that multiple groups of filtering components rotate synchronously around the axis of the cylinder body 1. Under the action of centrifugal force, the raw material in the pre-filter chamber 14 can flow into the post-filter chamber 15 through the filter plate 21 to filter the raw material. By arranging the second torsion spring between the hinge shaft 22 and the slider 25, the position state of the hinge shaft 22 and the filter plate 21 can be ensured, and the filter plate 21 can be prevented from driving the hinge shaft 22 to rotate relative to the slider 25 under the impact of the raw material, damaging the abutment between the adjacent two groups of filtering components and affecting the isolation between the pre-filter chamber 14 and the post-filter chamber 15.

[0049] In some embodiments, the second driving structure includes a lifting plate 32, a second driving member 33, and a plurality of connecting rods 34. A fixing rod 16 is connected between the upper end of the cylinder body 1 and the frame body 11. The fixing rod 16 is longitudinally arranged at the axis of the cylinder body 1. The lifting plate 32 is longitudinally slidably sleeved outside the fixing rod 16. The second driving member 33 is arranged on the frame body 11. The second driving member 33 is configured as a cylinder, and the output end of the cylinder is connected to the lifting plate 32. The plurality of connecting rods 34 are respectively arranged corresponding to the plurality of 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.

[0050] Specifically, as Figures 1 to 6 shown, when the second driving member 33 is started to drive the lifting plate 32 to move downward, under the action of the connecting rod 34, the slider 25 can be pushed to move along the chute 231 in a direction away from the axis of the cylinder body 1, and the hinge shaft 22 rotatably connected to the slider 25 can be driven to move synchronously, and at the same time, the filter plate 21 can be driven to move. When the second driving member 33 is started to drive the lifting plate 32 to move upward, under the action of the connecting rod 34, the slider 25 can be pulled to move in a direction close to the axis of the cylinder body 1, and the filter plate 21 can be driven to move. Through the reciprocating movement of the filter plate 21, the raw material in the filtered cavity 15 can be used to backflush and clean the filter plate 21.

[0051] In some embodiments, a plurality of adjusting rods 31 are provided, and are arranged in pairs corresponding to the plurality of chutes 231. The two adjusting rods 31 in the same group are symmetrically arranged on both sides of the chute 231. The adjusting rods 31 are horizontally arranged on the rotating plate 23. The end of the adjusting rod 31 facing the axis of the cylinder body 1 is defined as the inner end, and the other end is defined as the outer end. Each adjusting rod 31 is inclined from the outer end to the inner end in a direction close to the chute 231.

[0052] Specifically, as Figures 2 to 6As shown, in the initial state, the two filter plates 21 in the same group are in a flattened state, and at this time, the adjacent two groups of filter components are in contact with 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 driving structure II drives the hinge shaft 22 to move towards the axis of the cylinder 1, it will drive the filter plate 21 to move synchronously. During this process, the side of the filter plate 21 away from the hinge shaft 22 will contact the corresponding adjusting rod 31. Since the adjusting rod 31 is inclined, when the hinge shaft 22 moves, the filter plate 21 will rotate around the hinge shaft 22, making the two filter plates 21 arranged in a V shape, and keeping the adjacent two groups of filter components in contact until the hinge shaft 22 moves to one end of the sliding groove 231 close to the axis of the cylinder 1. At this time, the included angle between the two filter plates 21 is the smallest, the volume of the pre-filter chamber 14 is the smallest, and the volume of the post-filter chamber 15 is the largest; when the driving structure II drives the hinge shaft 22 to move away from the axis of the cylinder 1, it will drive the filter plate 21 to move. During this process, the filter plate 21 will reverse around the hinge shaft 22 under the action of the corresponding torsion spring I, making the two filter plates 21 in the same group in a flattened state again. At this time, the volume of the pre-filter chamber 14 returns to the largest state again, and the volume of the post-filter chamber 15 returns to the smallest state. When the filter plate 21 is blocked, the discharge port 13 is closed, and the raw materials in the post-filter chamber 15 can be made to flow by changing the size of the post-filter chamber 15 to perform backwashing on the filter plate 21.

[0053] In some embodiments, the driving structure III includes a screw rod 42, a driving member III 43, a gear I 44, and a gear II 45. The screw rod 42 is longitudinally arranged inside the cylinder 1. The gear I 44 and the gear II 45 are both rotatably arranged on the frame 11. The driving member III 43 is arranged on the frame 11. The driving member III 43 is a motor, and the output end of the motor is connected to the gear I 44 for driving the gear I 44 to rotate. The outer side of the gear II 45 is meshed with the gear I 44, and the inner side of the gear II 45 is in threaded cooperation with the screw rod 42. The scraper 41 is arranged at the lower end of the screw rod 42.

[0054] Specifically, as Figures 1 to 3 、 Figure 6As shown, during the process of driving the hinge shaft 22 to move radially along the cylinder body 1 by the driving structure two, when the hinge shaft 22 is at one end of the chute 231 close to the axis of the cylinder body 1, the volume of the pre-filter chamber 14 is the smallest, and the shape of the pre-filter chamber 14 is the same as that of the scraper 41. At this time, the driving member three 43 is started to drive the first gear 44 to rotate. Through the meshing transmission between the first gear 44 and the second gear 45, the second gear 45 can be driven to rotate, and through the thread fit between the second gear 45 and the screw 42, the screw 42 can be driven to move up and down. When the screw 42 moves downward, the scraper 41 provided at the lower end of the screw 42 can be driven to move synchronously. During this process, the raw materials located below the scraper 41 will flow into the upper part of the scraper 41 through the filter holes provided on the scraper 41, while the impurities located below the scraper 41 will be intercepted below the scraper 41. When the scraper 41 moves to the bottom of the cylinder body 1, the impurities will be intercepted between the impurity collection groove provided at the lower end of the scraper 41 and the bottom of the cylinder body 1, realizing the separation of the raw materials and the impurities.

[0055] In some embodiments, the feed inlet 12 includes a first feed inlet 121 provided at the center of the scraper 41 and a second feed inlet 122 provided on the side wall of the screw 42. The inside of the screw 42 is hollow and open at both ends. When the scraper 41 is at the uppermost part of the cylinder body 1, the inside of the screw 42 communicates with the pre-filter chamber 14 through the first feed inlet 121. When the scraper 41 is at the lowermost part of the cylinder body 1, the inside of the screw 42 communicates with the pre-filter chamber 14 through the second feed inlet 122.

[0056] Specifically, as Figure 2 、 Figure 3 and Figure 6 shown, when the scraper 41 is at the uppermost part of the cylinder body 1, the raw materials will be discharged from the lower end of the screw 42 and flow into the pre-filter chamber 14 through the first feed inlet 121 provided on the scraper 41 for filtration. When the scraper 41 moves to the lowermost part of the cylinder body 1 under the action of the driving structure three, the first feed inlet 121 is blocked by the bottom of the cylinder body 1. At this time, the raw materials will be discharged from the second feed inlet 122 provided on the side wall of the screw 42 and flow into the pre-filter chamber 14 for filtration.

[0057] In some embodiments, a baffle 46 capable of closing the first feed inlet 121 is provided at the first feed inlet 121. The upper end of the baffle 46 is connected to the screw 42 through an elastic member 47, and the elastic member 47 is set as a spring.

[0058] Specifically, as Figure 2 、 Figure 3 and Figure 6As shown in the figure, when the scraper 41 is at the uppermost position of the cylinder body 1, during the process of the raw materials being discharged from the lower end of the screw 42, the baffle 46 at the first feed port 121 will be impacted, causing the baffle 46 to move downward under the force, and stretching the elastic member 47 to store energy. As the baffle 46 moves, the first feed port 121 will be opened. At this time, the raw materials can flow into the pre-filter chamber 14 through the first feed port 121 for filtration. After the addition of the raw materials is completed, the baffle 46 loses the acting force of the raw materials and moves upward under the action of the elastic member 47 to reset, closing the first feed port 121 again to prevent impurities from entering the cylinder body 1 through the first feed port 121 and affecting the filtration of the raw materials; when the scraper 41 is driven downward by the third driving structure, the raw materials below the scraper 41 flow above the scraper 41 through the filter holes provided on the scraper 41, while the impurities are intercepted below the scraper 41. During this process, the baffle 46 remains closed to the first feed port 121 under the action of the elastic member 47, preventing the impurities located below the scraper 41 from directly moving above the scraper 41 and affecting the collection of impurities in the pre-filter chamber 14. During the downward movement of the scraper 41, the raw materials will flow into the pre-filter chamber 14 through the second feed port 122 provided on the side wall of the screw 42 for filtration; when the scraper 41 moves to the lowermost position of the cylinder body 1, the raw materials will continue to flow into the pre-filter chamber 14 through the second feed port 122 for filtration.

[0059] As Figures 1 to 6 shown, the present invention also provides a method for processing raw materials for sustainable aviation fuel using the above-mentioned raw material processing device, which specifically includes the following steps:

[0060] S1: Feeding: Add the raw materials to be filtered into the pre-filter chamber 14 provided inside the cylinder body 1 through the feed port 12;

[0061] S2: Filtration: Drive the filter plate 21 to rotate around the axis of the cylinder body 1 through the first driving structure, so that under the action of centrifugal force, the raw materials in the pre-filter chamber 14 can enter the post-filter chamber 15 after being filtered by the filter plate 21 and be discharged from the discharge port 13, while the impurities are intercepted in the pre-filter chamber 14;

[0062] S3: Backwashing and cleaning: When the filter plate 21 is blocked, close the discharge port 13, drive the hinge shaft 22 to reciprocate along the radial direction of the cylinder body 1 through the second driving structure, and drive the filter plate 21 to reciprocate, so that during this process, the raw materials in the post-filter chamber 15 are used to backwash and clean the filter plate 21, and the impurities blocked in the filter holes are cleaned out;

[0063] S4: Collection and cleaning: When the filter plate 21 moves to a position close to the axis of the cylinder body 1, drive the scraper 41 to move downward through the third driving structure to collect and clean the impurities intercepted in the pre-filter chamber 14, realizing the separation of impurities from the raw materials;

[0064] S5: Continue filtering: After cleaning the filter plate 21, open the discharge port 13, and continue to filter the raw materials in the pre-filter chamber 14 through the filter plate 21 until the filtering is completed.

[0065] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
