Technical Field

[0001] This invention relates to the field of vegetable oil processing technology, and in particular to a purification apparatus for refining crude rice bran oil. Background Technology

[0002] The field of vegetable oil processing technology encompasses a series of processing steps, including pretreatment, pressing, filtration, and purification, to obtain qualified vegetable oils. Its core content involves treating vegetable oil raw materials and crude oil through physical and chemical means to remove impurities, moisture, odors, and harmful components, thereby improving the quality, purity, and safety of the oils. This field covers multiple key stages, including raw material screening, pretreatment, crude oil refining, and finished product packaging. It is widely used in the grain and oil processing industry and is an important technological support for ensuring the supply of pure and safe vegetable oil products to the market.

The separation device includes: a separation box; a pressing groove slidably connected inside the separation box; a first cylinder installed inside the separation box; the drive end of the first cylinder fixedly connected to the right end of the pressing groove; a pressing slide rail fixedly connected to the pressing groove; raw material feeding troughs on both the front and back of the pressing groove; a raw material feeding rod inside the raw material feeding trough; a rice bran raw material silo installed inside the separation box; a raw material baffle slidably connected to the right side of the rice bran raw material silo; a raw material baffle groove on the raw material silo; and the raw material baffle rotatably connected to the raw material feeding rod.

[0004] Existing separation devices only achieve rice bran oil pressing and separation through pressing tanks and cylinders in the separation box.

[0035] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0036] Example 1, Reference Figure 1 , Figure 2 as well as Figure 3As shown, a purification device for refining crude rice bran oil includes a workbench 1, which provides stable installation support and operating benchmark for the entire device, ensuring that the various mechanisms of the device will not shift or shake during operation. A mixing tank 2 is fixedly connected to the upper end of the workbench 1. The mixing tank 2 is used to complete the mixing, stirring, and high-temperature conditioning pretreatment of the rice bran raw material, providing qualified raw materials that meet the process requirements for subsequent oil pressing and purification processes. A conveying mechanism 3 is fixedly connected to the bottom of the workbench 1. The conveying mechanism 3 is used to continuously and stably convey the pretreated rice bran raw material in the mixing tank 2, ensuring the continuous production capacity of the entire device. A collecting mechanism 4 is fixedly connected to the bottom of the conveying mechanism 3. The collecting mechanism 4 is used to centrally collect and smoothly guide the rice bran raw material conveyed by the conveying mechanism 3, avoiding the raw material from shifting during the conveying and transfer process. To address the issue of spillage and accumulation, the bottom of the collection mechanism 4 is fixedly connected to an oil pressing mechanism 5. The oil pressing mechanism 5 continuously mechanically presses the conditioned rice bran raw material, fully extracting the oil from within and initially separating the crude rice bran oil from the residue. The bottom of the oil pressing mechanism 5 is also fixedly connected to a filtration mechanism 6, which performs fine filtration and purification of the extracted crude rice bran oil. This effectively removes oil residue and solid impurities, significantly improving the purity and quality of the finished crude rice bran oil. All mechanisms are arranged sequentially from top to bottom, enabling a continuous, integrated process from raw material pretreatment to final purification of the crude rice bran oil. This effectively shortens the material transport path, reduces losses and contamination risks during transport, and significantly improves the overall production efficiency of the equipment while minimizing manual intervention costs.

[0037] In the operation of this embodiment, the entire process of continuous refining of crude rice bran oil is achieved through the cooperation of the workbench 1, mixing tank 2, transport mechanism 3, collection mechanism 4, oil pressing mechanism 5, and filtration mechanism 6. The workbench 1 provides stable support for each mechanism to prevent deviation and shaking during operation; the mixing tank 2 completes the mixing and conditioning of raw materials to provide qualified raw materials; the transport mechanism 3 realizes continuous and directional transportation of raw materials to ensure continuous production; the collection mechanism 4 centrally guides the raw materials to avoid spillage and blockage; the oil pressing mechanism 5 realizes the full extraction of oil and the separation of oil residue; the filtration mechanism 6 removes impurities to improve the quality of crude oil, shortens the overall transfer path, reduces losses and pollution, improves production efficiency, and reduces labor costs.

[0038] Example 2, please refer to further details. Figure 4 , Figure 5 as well as Figure 6As shown, this embodiment, based on embodiment one, utilizes the cooperation of mixing tank 2 with tank body 21, mixing mechanism 22, and wall scraping mechanism 24 to provide a closed and clean mixing and conditioning space for rice bran raw materials. Processing tank 211 ensures stable conditioning temperature and pressure. High-temperature steam generated by steam generator 212 diffuses through input pipe 213 and funnel 214, softening raw material cells and sterilizing and deodorizing. Motor 221 of mixing mechanism 22 drives transmission rod 222 and rotating rod 223 to operate. Gear 225 meshes with the tooth groove of processing tank 211, enabling stirring rod 224 to achieve three-dimensional stirring and improve mixing uniformity. Wall scraping strip 242 of wall scrapes off raw materials from the inner wall, spiral turning plate 244 prevents accumulation, and discharge device 215 discharges materials quantitatively, effectively improving raw material utilization, ensuring conditioning consistency, and laying the foundation for subsequent refining processes.

[0039] The mixing tank 2 includes a tank body 21, which provides a closed and clean processing space for the mixing and conditioning of rice bran raw materials, preventing the raw materials from being contaminated by the external environment during processing. A mixing mechanism 22 is fixedly connected to the upper middle part of the tank body 21. The mixing mechanism 22 is used to perform all-round three-dimensional stirring and mixing of the rice bran raw materials inside the tank body 21, breaking up the stacked and layered state of the raw materials, ensuring the uniformity of the mixing and the consistency of the conditioning process. A feed inlet 23 is fixedly connected to one side of the upper end of the tank body 21, which provides a stable feeding channel for the rice bran raw materials, ensuring that the raw materials can smoothly enter the interior of the tank body 21 to complete subsequent processing operations. A wall scraping mechanism 24 is fixedly connected to the bottom of the outer surface of the mixing mechanism 22. The wall scraping mechanism 24 can rotate synchronously with the operation of the mixing mechanism 22, continuously cleaning and scraping the inner wall of the tank body 21, preventing the rice bran raw materials from adhering to the inner wall of the tank body 21 and being unable to participate in the mixing and conditioning operations. At the same time, it prevents the raw materials from charring and deteriorating due to long-term adhesion to the inner wall, effectively improving the overall utilization rate of the raw materials and reducing unnecessary waste of materials.

[0040] Furthermore, the tank body 21 includes a processing tank 211, which provides a core sealed processing chamber for the mixing and conditioning of rice bran raw materials, ensuring the stability of temperature and pressure during the conditioning process. A steam generator 212 is fixedly connected to the bottom of the inner cavity of the processing tank 211. The steam generator 212 can continuously generate high-temperature steam that meets the process requirements, providing a stable heat and moisture source for the conditioning of rice bran raw materials. The inner cavity of the processing tank 211 is provided with toothed grooves, which can mesh with corresponding transmission components to provide stable transmission support for the compound motion of the stirring structure. An input pipe 213 is fixedly connected to the output end of the steam generator 212. The input pipe 213 is used to guide the high-temperature steam generated by the steam generator 212 in a directional manner, ensuring that the high-temperature steam can be stably delivered to the designated location. A funnel 214 is fixedly connected to the upper end of the input pipe 213, which can receive the input pipe 214. 3. The high-temperature steam is conveyed and evenly diffused upwards into the material interior of the processing tank 211. At the same time, it can receive the rice bran raw material after conditioning and provide a guiding and gathering function for the discharge of the raw material. The bottom of the funnel 214 is fixedly connected to the feeder 215, which can quantitatively control the discharge of the rice bran raw material after conditioning and ensure that the raw material can fall steadily and continuously according to the feeding requirements of subsequent processes, avoiding the problem of blockage in subsequent processes caused by excessive feeding, and also preventing the production efficiency of the device from being affected by insufficient feeding. After the high-temperature steam diffuses into the raw material through the input pipe 213 and the funnel 214, it can effectively soften the cell structure of the rice bran raw material, greatly reducing the difficulty of subsequent oil precipitation. At the same time, it can kill the microorganisms and insect eggs contained in the raw material, improve the food safety level of the final finished oil, and remove some odor substances in the raw material, optimizing the basic quality of the crude rice bran oil.

[0041] Furthermore, the mixing mechanism 22 includes a motor 221, which provides stable power output for the operation of the entire mixing mechanism 22, ensuring continuous and stable mixing. A transmission rod 222 is fixedly connected to the output end of the motor 221. The transmission rod 222 rotates synchronously with the output shaft of the motor 221, stably transmitting the power of the motor 221 to each corresponding working component. A rotating rod 223 is fixedly and rotatably connected to the upper part of the outer surface of the transmission rod 222. The rotating rod 223 can complete its revolution synchronously with the rotation of the transmission rod 222, and simultaneously rotate around its own axis. Two symmetrically arranged stirring rods 224 are fixedly connected to the outer surface of the rotating rod 223. The stirring rods 224 can rotate synchronously with the revolution and rotation of the rotating rod 223, thus improving the processing efficiency. The rice bran raw material inside tank 211 undergoes comprehensive three-dimensional stirring without any dead angles, effectively breaking up the accumulation and stratification of the raw material, greatly improving the uniformity of the mixing, and allowing the raw material to fully contact with high-temperature steam, ensuring the overall consistency of the conditioning process. This lays a uniform and stable material foundation for subsequent refining and purification processes. Both ends of the rotating rod 223 are fixedly connected to gears 225 that cooperate with the processing tank 211. The gears 225 can mesh with the tooth grooves inside the processing tank 211 to complete the transmission. During the revolution of the rotating rod 223 with the transmission rod 222, the meshing action of the gears 225 and the tooth grooves drives the rotating rod 223 to complete a stable rotational motion. There is no need to set up additional rotation drive components, which effectively simplifies the transmission structure of the device, reduces the energy consumption and the probability of failure of the device, and ensures the operational stability of the stirring operation.

[0042] Furthermore, the scraping mechanism 24 includes a rotating ring 241, which is fixedly connected to the transmission rod 222 of the mixing mechanism 22. The rotating ring 241 can synchronously complete a stable circular rotation operation with the rotation of the transmission rod 222. Four scraping strips 242 arranged in an array are fixedly connected to the bottom end of the rotating ring 241. The four scraping strips 242 can synchronously rotate with the rotating ring 241. The four scraping strips 242 are used to scrape off the rice bran from the inner wall of the processing tank 211. During rotation, the scraping strips 242 continuously move against the inner wall of the processing tank 211, completely scraping off the rice bran material adhering to the inner wall, avoiding the problem of charring and deterioration caused by long-term adhesion of the material to the inner wall. At the same time, it ensures that all raw materials can fully participate in the mixing and conditioning process, effectively improving the overall utilization rate of raw materials and reducing unnecessary waste. A connecting plate 243 is fixedly connected to the bottom end of the four scraping strips 242. The connecting plate 243 can... The bottom ends of the four scraping strips 242 are stably connected and fixed, which effectively improves the structural stability of the scraping strips 242 during rotation and avoids deformation and displacement of the scraping strips 242 during scraping operations. The bottom end of the connecting plate 243 is rotatably connected to the funnel 214, which can provide stable rotational support for the bottom end of the scraping strips 242, further ensuring the smooth operation of the scraping action. The bottom of the outer surface of the transmission rod 222 is fixedly connected to a spiral turning plate 244 for turning materials. The spiral turning plate 244 can rotate synchronously with the rotation of the transmission rod 222, continuously turning and conveying the material at the bottom of the processing tank 211 upwards, avoiding the accumulation and settling of raw materials at the bottom of the tank, realizing the circulation and convection of materials between the upper and lower layers inside the processing tank 211, further enhancing the uniformity of raw material mixing and conditioning, and at the same time avoiding the problem of raw material accumulation and blockage at the inlet of the funnel 214, ensuring that the raw materials can be smoothly discharged.

[0043] Example 3, please refer to further details. Figure 7 , Figure 8 As shown, this embodiment, based on embodiment two, achieves stable conveying and smooth transfer of rice bran raw materials through the cooperation of the transport mechanism 3 and the collection mechanism 4. The support platform 31 provides stable installation support for the drive components of the transport mechanism 3, the second motor 32 provides power, the second transmission rod 33 cooperates with the connecting roller 36 to drive the transport belt 34 to rotate, the transport plate 38 limits the raw materials to prevent slippage, the correction plate 35 levels the raw materials to prevent spillage and forms a uniform material layer, the transmission belt 37 realizes linkage with the oil pressing mechanism 5, reduces energy consumption and simplifies the transmission structure; the collection hopper 41 collects and guides the raw materials, the connecting block 45 fixes the vibration block 44, the vibration block 44 cooperates with the spring 43 to drive the collection hopper 41 to vibrate, avoid the raw materials to stick and block, ensure that the raw materials continuously enter the oil pressing mechanism 5, improve the raw material utilization rate and the continuous operation capability of the equipment.

[0044] Furthermore, the transport mechanism 3 includes a support platform 31, which provides a stable mounting foundation for the drive components of the transport mechanism 3, ensuring the structural stability of the drive components during operation. A second motor 32 is fixedly connected to the upper end of the support platform 31. The second motor 32 provides stable power output for the overall operation of the transport mechanism 3 and can also provide synchronous power transmission for subsequent oil pressing processes. A second transmission rod 33 is fixedly connected to the output end of the second motor 32. The second transmission rod 33 can rotate synchronously with the output shaft of the second motor 32, stably transmitting the power of the second motor 32 to each corresponding working component. The second transmission rod 33 and the working... The right side of the inner cavity of workbench 1 is rotatably connected. Workbench 1 provides stable support and limit for the rotation of transmission rod 33, ensuring that there is no radial offset during the rotation of transmission rod 33. A connecting roller 36 is fixedly connected to the upper left side of workbench 1. The connecting roller 36 provides stable rotational support and tension for the left side of conveyor belt 34, ensuring that conveyor belt 34 can complete stable and smooth circulation. The outer surface of transmission rod 33 and the connecting roller 36 are together wound and connected to the conveyor belt 34. Under the drive of transmission rod 33, the conveyor belt 34 can work with the connecting roller 36 to complete continuous circulation, achieving stable rice bran raw material. Continuous directional conveying is employed, with several conveyor plates 38 fixedly connected to the outer surface of the conveyor belt 34. These plates 38 move synchronously with the conveyor belt 34, receiving and limiting the rice bran material on the belt to prevent it from sliding down during transport, ensuring the stability and integrity of the material conveying process. A transmission belt 37 is wound around the front of the transmission rod 33 and the front of the oil pressing mechanism 5, synchronously transmitting power from the transmission rod 33 to the oil pressing mechanism 5. This achieves synchronized operation of the material conveying and oil pressing processes, eliminating the need for additional drive components for the oil pressing mechanism 5 and effectively reducing equipment costs. The overall energy consumption is reduced, the overall transmission structure of the equipment is simplified, and the synchronicity and stability of each process of the equipment are improved. Correction plates 35 are fixedly connected to the upper part of both sides of the connecting roller 36. The two correction plates 35 are used to level the rice bran from left to right. The correction plates 35 can continuously limit and level the raw materials on the conveyor belt 34 in the left and right directions during the raw material transportation process, so as to prevent the raw materials from spilling from both sides of the conveyor belt 34 and ensure the integrity of the raw material transportation process. At the same time, it can make the raw materials form a uniform material layer on the conveyor belt 34, providing stable and uniform feeding conditions for the subsequent oil pressing process, and ensuring the stability and oil extraction efficiency of the oil pressing operation.

[0045] Furthermore, the collecting mechanism 4 includes a collecting hopper 41, which provides a centralized collection space for the rice bran raw material conveyed by the transport mechanism 3. It also guides and gathers the raw material, allowing it to smoothly and stably enter the oil pressing mechanism 5 below. Connecting blocks 45 are fixedly connected to the left and right sides of the collecting hopper 41. These connecting blocks 45 provide stable support for the installation of the vibrating block 44, ensuring the stability of the vibration structure. The bottoms of the two connecting blocks 45 are rotatably connected to the vibrating block 44. The vibrating block 44 generates continuous reciprocating oscillation under the impact of the falling raw material, thereby driving the collecting hopper 41 to produce a synchronous vibration effect. The upper end of the collecting hopper 41 is fixedly connected to the bottom of the correction plate 35, ensuring that the upper end of the collecting hopper 41 completely receives all the raw material conveyed by the transport belt 34, preventing the raw material from being damaged during transfer. To prevent spillage, fixing blocks 42 are fixedly connected to both sides of the collecting hopper 41 and the vibrating block 44. The fixing blocks 42 provide stable mounting points for both ends of the spring 43, ensuring that the spring 43 can function stably. The ends of the two fixing blocks 42 on the same side are fixedly connected to the spring 43. The spring 43 can work together to complete the elastic extension and contraction during the swing of the vibrating block 44, causing the collecting hopper 41 to generate high-frequency small-amplitude vibrations synchronously. This allows the raw materials in the collecting hopper 41 to slide down quickly and smoothly, preventing the raw materials from adhering and accumulating on the inner wall of the collecting hopper 41. This effectively prevents the problem of material blockage and ensures that the raw materials can continuously and stably enter the oil pressing mechanism 5 below, greatly improving the continuous operation capability of the device. At the same time, it can prevent the raw materials from remaining inside the collecting hopper 41, further improving the overall utilization rate of the raw materials.

[0046] Example 4, please refer to further details. Figure 8 , Figure 9 , Figure 10 as well as Figure 11 As shown, this embodiment, based on embodiment three, achieves efficient extraction and fine purification of crude rice bran oil through the cooperation of the oil pressing mechanism 5 and the filtration mechanism 6. The outer shell 51, together with the support 52 and the fixed platform 53, ensures structural stability during the oil pressing process. The bar array 54, together with the connector 551, screw 1 552, screw 2 553, and screw 3 554 of the oil pressing component 55, achieves step-by-step extrusion, increasing the oil yield and preventing material blockage. The breaking trough further promotes oil precipitation. The oil residue collection box 61, together with the baffle 63, prevents material splashing. The W-shaped filter plate 624 improves filtration accuracy and efficiency. The handwheel 621 and scraper 623 of the cleaning mechanism 62 facilitate cleaning of the filter plate. The sliding block 612 and the limiting plate 613 facilitate oil residue cleaning and prevent oil leakage. The oil discharge plate 64 and the support column 66 ensure stable collection, greatly improving the quality of the finished crude oil and the convenience of equipment operation and maintenance.

[0047] Furthermore, the oil pressing mechanism 5 includes a housing 51, which provides a closed installation and operating space for the core components of the oil pressing operation, preventing oil and raw materials from splashing and leaking out during the pressing process. It also isolates the housing from external contamination, ensuring the cleanliness of the extracted rice bran crude oil. A bracket 52 is fixedly connected to the left side of the outer surface of the housing 51, providing stable auxiliary support to the left side of the housing 51 and further improving the structural stability of the housing 51 installation. This prevents the housing from shifting or shaking due to excessive pressure during the pressing process. A fixed platform 53 is fixedly connected to the bottom of the housing 51, providing stable bottom support for the entire oil pressing mechanism 5 and ensuring the overall structural stability during the pressing operation. The inner cavity of the housing 51 is provided with several rows 54, which cooperate with the oil pressing component 55 to form the pressing chamber space. The pressing and oil extraction process of rice bran provides a stable chamber environment. The gaps between the strips 54 allow the extracted crude rice bran oil to drain smoothly, achieving initial separation of oil and residue. An oil pressing component 55 meshes within the inner cavity of the strips 54. Driven by a power source, the component rotates stably, continuously pressing and pushing the rice bran material into the inner cavity of the strips 54, resulting in full extraction of crude rice bran oil. A crushing trough is provided within the inner cavity of the strips 54. This trough continuously crushes and shears the rice bran material as the pressing component 55 moves it, further disrupting the cell structure and allowing for more complete extraction of oil. This effectively improves the oil extraction efficiency, reduces residual oil content in the residue, and prevents compaction and slippage within the pressing chamber, ensuring continuous and stable oil extraction.

[0048] Furthermore, the oil pressing assembly 55 includes a connector 551, which is the power input component of the oil pressing assembly 55. It can stably transmit externally transmitted power to the entire screw press structure. The outer surface of the connector 551 and the outer surface of the transmission rod 33 are wound together with a transmission belt 37. The transmission belt 37 can stably transmit the power output from the transmission rod 33 of the transport mechanism 3 to the connector 551, realizing the synchronous linkage between the conveying process and the oil pressing process. This ensures that the operating rhythms of the two processes are perfectly matched, avoiding problems such as material blockage or idling caused by mismatch between the feeding and oil pressing rhythms. The connector 551 is rotatably connected to the outer shell 51. The outer shell 51 provides stable support and limits for the rotation of the connector 551, ensuring that there is no radial offset during the rotation of the connector 551. A screw press 552 is fixedly connected to the rear of the connector 551. The screw press 552 can rotate synchronously with the connector 551, performing preliminary pushing and pre-compression operations on the rice bran raw material entering the pressing chamber, allowing the raw material to... The screw press 552 is stably connected to the rear of the pressing chamber. The second screw press 553 rotates synchronously with the connector 551, performing intermediate pressing on the raw material to further increase the pressing pressure and allow the oil inside the raw material to begin to be extracted in large quantities. The third screw press 554 is also fixedly connected to the rear of the second screw press 553. It rotates synchronously with the connector 551 to perform final strong pressing on the raw material, allowing the residual oil inside the raw material to be fully extracted. The diameters of the screw press 552, the second screw press 553, and the third screw press 554 gradually increase, forming a continuously narrowing pressing chamber space inside the bar 54. This generates progressively increasing pressing pressure on the incoming raw material, achieving a step-by-step pressurization effect. This avoids the problem of material compaction and blockage caused by single strong pressing. At the same time, it allows the raw material to complete the full oil extraction during the gradual pressurization process, significantly improving the oil extraction rate, reducing the residual oil content in the residue, and effectively improving the oil extraction efficiency and overall utilization rate of the raw material.

[0049] Furthermore, the filtration mechanism 6 includes an oil residue collection box 61, which is used to collect and store the oil residue discharged from the oil pressing mechanism 5, and at the same time provide a stable working space for the filtration and purification operation. A baffle 63 is fixedly connected to the upper part of the inner cavity of the oil residue collection box 61. The baffle 63 can guide and limit the flow of rice bran crude oil and oil residue falling from the oil pressing mechanism 5, avoiding the problem of splashing everywhere during the falling process, and ensuring that the material can accurately fall on the filter component to complete the filtration operation. A cleaning mechanism 62 is rotatably connected to the upper part of the inner cavity of the oil residue collection box 61. The cleaning mechanism 62 can conveniently clean the oil residue impurities trapped on the surface of the filter component, avoid the filter holes of the filter component from becoming blocked, and ensure that the filtration process can continue to operate stably. An oil drain plate 64 is fixedly connected to the bottom of the mechanism 62. The oil drain plate 64 is used to receive the clean rice bran crude oil after filtration and purification, and can stably collect and discharge the finished crude oil. Three support columns 66 are fixedly connected to the bottom of the oil drain plate 64. The three support columns 66 can provide stable bottom support for the oil drain plate 64, ensuring that the oil drain plate 64 will not deform or shake during operation. The bottom of the three support columns 66 is fixedly connected to a connecting block 2 65. The connecting block 2 65 can stably connect and fix the bottom of the three support columns 66, and at the same time provide corresponding installation support for the adjustment operation of the cleaning mechanism 62, further improving the structural stability of the entire filtration mechanism 6 and ensuring that the filtration and cleaning operations can be carried out smoothly.

[0050] The oil sludge collection box 61 includes a second outer shell 611, which provides a closed cavity space for collecting and storing oil sludge, and also provides a stable installation foundation for the various internal components. A sliding block 612 is slidably connected to one side of the inner cavity of the second outer shell 611. The sliding block 612 can be easily pulled and slid along the inner cavity of the second outer shell 611. After the device has finished its operation, the operator can pull out the sliding block 612 to centrally clean and transfer the oil sludge collected inside the second outer shell 611, greatly reducing the operational difficulty of oil sludge cleaning and improving the ease of maintenance of the device. A limiting plate 613 is rotatably connected to the inner wall near the sliding block 612. The limiting plate 613 can surround... The device can rotate flexibly around its connecting shaft. The limiting plate 613 is used to limit the sliding block 612 and prevent rice bran oil from entering the outer shell 611. After the sliding block 612 is pushed into the outer shell 611 and installed, the limiting plate 613 can rotate to the corresponding position to limit and fix the sliding block 612, preventing the sliding block 612 from sliding out on its own during device operation. At the same time, the limiting plate 613 can effectively block the sliding gap between the sliding block 612 and the outer shell 611, preventing rice bran oil from entering the sliding gap and avoiding the problem of oil leakage and waste. It also ensures the cleanliness of the inside of the device and reduces the maintenance and cleaning costs of the device.

[0051] Furthermore, connecting block 2 65 includes a handwheel 621, which provides a convenient manual operation point for the operator, allowing them to easily drive the cleaning mechanism 62 to complete the cleaning operation. A threaded rod 622 is fixedly connected to the front of the handwheel 621. The threaded rod 622 can complete the circumferential rotation operation synchronously with the rotation of the handwheel 621, converting the manually input rotational force into linear drive power. A scraper 623 is threadedly connected to the outer surface of the threaded rod 622. Under the rotation of the threaded rod 622, the scraper 623 can complete a stable horizontal linear movement along the axis of the threaded rod 622 to scrape and clean the oil residue on the surface of the filter plate. A housing 3 626 is fixedly connected to the top left side of the inner cavity of the workbench 1. The housing 3 626 provides a stable installation and protection space for the core filter components, ensuring that the filtration operation can be carried out in a closed and clean environment. Two sliding rods 625 are fixedly connected to the bottom of the housing 3 626. The two sliding rods 625 can provide stable guidance and limit for the movement of the scraper 623. The two sliding rods 625 work together The scraper 623 is slidably connected to the filter plate 624, ensuring that the scraper 623 remains horizontal during movement and does not rotate or deviate. This ensures that the scraper 623 always adheres to the surface of the filter plate to complete the scraping operation, improving the cleaning effect. A W-shaped filter plate 624 is fixedly connected to the inner cavity of the outer shell 626. The W-shaped filter plate 624 provides the core filter medium for the filtration and purification of rice bran crude oil. It can effectively trap oil residue and solid impurities mixed in the crude oil. The W-shaped filter structure can significantly increase the contact area between the crude oil and the filter plate, prolong the residence time of the crude oil on the filter plate, and significantly improve the filtration accuracy and efficiency, effectively improving the purification effect of rice bran crude oil and ensuring the purity and quality of the final product crude oil. During the movement, the scraper 623 can adhere to the surface of the W-shaped filter plate 624 to complete the scraping operation, scraping all the oil residue and impurities trapped on the surface of the filter plate into the inner cavity of the oil residue collection box 61, realizing convenient cleaning of the filter structure, effectively avoiding the problem of filter plate pore blockage, and ensuring the continuous and stable operation of the filtration process.
