Description

Technical Field

[0001] This invention relates to the field of leaching equipment technology, and more particularly to a horizontal rotary leaching equipment for grain and oil production. Background Technology

[0002] The flat rotary extractor for grain and oil production is a specialized piece of equipment for grain and oil processing. Through its specific structural design and working principle, it achieves efficient, continuous, and stable extraction of grain and oil, thereby improving the production efficiency and product quality of grain and oil processing. This equipment has the advantages of compact structure, simple operation, and convenient maintenance, and is widely used in the grain and oil processing industry. It is of great significance for improving the technical level and economic benefits of the entire grain and oil processing industry chain.

[0003] Traditional leaching machines typically rely on rotation and gravity to leach oils and discharge leached materials. After leaching, the materials are tilted and discharged naturally by gravity. This process often results in waste materials generated during the reaction of the raw materials with the solvent adhering to the surface of the leaching machine's rotating section, making complete discharge difficult. Alternatively, as the waste material rotates to the discharge port, its compacted state prevents it from naturally dispersing and falling downwards. This can cause blockages or incomplete removal during the discharge process, impacting the machine's performance and causing downtime. Furthermore, the adhesion of waste material to the rotating section affects its cleanliness. When new materials are added to react with the solvent, gaps may form between the rotating section and the material, or gaps may appear inside the material during addition. These gaps allow the solvent to quickly penetrate to the bottom, preventing even contact and chemical reaction with the material, thus affecting the leaching effect, reducing leaching efficiency, and lowering product quality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage of gaps when the material is introduced, or the solvent penetration effect is affected by the contamination of the grid. To this end, we propose a flat rotary extractor for grain and oil production.

[0005] To achieve the above objectives, this application adopts the following technical solution: a grain and oil production rotary extractor, comprising an extractor body, three spray devices installed on one side of the extractor body, an extractor filter screen fixedly connected to the middle of the inner wall of the extractor body, a rotating shell rotatably connected to the middle of the extractor body, a plurality of partitions fixedly connected to the surface of the rotating shell, an outer circular plate fixedly connected to one side of the plurality of partitions, and the grain and oil production rotary extractor further comprising a striking rod and a scraper. The inner wall of the partition is equipped with a striking mechanism so that the striking rod deflects and then resets, striking both sides of the partition from the inside, thereby causing the partition to vibrate and increasing the falling speed of the adsorbed substances on its surface, thus preventing the adsorbed and sticky substances on the surface of the partition from affecting the subsequent leaching process. The cleaning mechanism is connected to the tapping mechanism so that the scraper moves back and forth repeatedly along both sides of the partition to remove solvent or adhesives from the surface of the partition and maintain the cleanliness of the partition surface. An auxiliary mechanism is connected to the cleaning mechanism to drive the scraper to move up and down during the scraper's movement, causing slight vibrations that shake off the dirt adhering to the scraper and increase the scraper's cleaning power for stubborn dirt. A protective mechanism is installed on the top of the partition to seal the top area of ​​the scraper and prevent material from entering the interior of the partition.

[0006] Preferably, the striking mechanism includes: The motor has a drive gear mounted on its top output end. A support plate is fixedly connected to the inner wall of the partition. A transmission gear is rotatably connected to the top of the support plate via a rotating shaft. A first gear is fixedly connected to the top of the transmission gear. A second gear is rotatably connected to the top of the support plate. A toothed chain is meshed with the surface of the first gear. Two rotating rods are rotatably connected to the middle of the support plate. A third gear is fixedly connected to the top of each rotating rod and meshes with the inner wall of the toothed chain. Two fourth gears are fixedly connected to the surface of each rotating rod. Two mounting brackets are fixedly connected to the inner wall of the partition. Four central shafts are fixedly connected to the top of each mounting bracket. A housing is rotatably connected to the surface of each central shaft. One end of a striking rod is fixedly connected to the surface of the housing. An inclined plate is fixedly connected to one side of the housing. A first spring is fixedly connected to one side of the housing. The other end of the first spring is fixedly connected to the inner wall of the partition. A drive device is mounted on one side of the leaching unit. A delivery pipe is fixedly connected to the bottom of the leaching unit.

[0007] Preferably, the cleaning mechanism includes: The U-shaped frame has a long groove at its top, and a sliding rod is slidably connected to the inner wall of the long groove. The bottom of the sliding rod is fixedly connected to a toothed chain. The top of the inner wall of the partition has a groove that matches the movement trajectory of the sliding rod.

[0008] Preferably, the auxiliary mechanism includes: The sliders are four in number and evenly distributed on both sides of the U-shaped frame. Two wave grooves are opened on both sides of the inner wall of the partition, and the sliders are slidably connected to the inner wall of the wave grooves.

[0009] Preferably, the protective mechanism includes: Two baffles are distributed on both sides of the top of the partition. An extension rod is fixedly connected to both sides of the baffle. Two short grooves are opened on both sides of the inner wall of the partition. The extension rods are slidably connected to the inner wall of the short grooves.

[0010] Preferably, the top of the scraper has a square structure, and one side of the bottom of the scraper has an arc corner, which is slidably connected to one end of the baffle.

[0011] Preferably, the two sides of the U-shaped frame are slidably connected to the two sides of the inner wall of the partition, and the surface of the scraper is slidably connected to the outer surface of the partition.

[0012] Preferably, a plurality of second springs are fixedly connected inside the baffle, and the top of the second springs is fixedly connected to the baffle.

[0013] The technical effects and advantages of this invention are as follows: In this invention, the material is carried and rotated through the gap between the partitions. Then, the solvent sprayed by the spraying device comes into contact with the material, causing the material to leach downwards and extract the grain and oil. The grain and oil are then filtered by the leaching filter screen, so that the grain and oil mixture enters the bottom of the leaching unit and is then transported to the subsequent processing steps by the conveying pipe. Afterward, the partition rotates to a designated area to pour out the residue of the leached material from the inside of the leaching unit. The partition continues to rotate to introduce new material for leaching production.

[0014] In this invention, after the partition rotates to the pouring area, the motor drives the striking mechanism to operate, causing the striking rod to repeatedly strike the partition, causing the surface of the partition to vibrate. This allows the material placed on the side of the partition to slide down through the vibration, effectively preventing material residue on the side of the partition. This ensures that the leachated material can be discharged efficiently, avoiding blockages and incomplete discharge of material residue during material discharge.

[0015] In this invention, the scraper repeatedly moves along the surface of the partition to clean the surface of the partition. At the same time, the scraper vibrates up and down to shake off the scraped waste, thus preventing the surface of the partition from adsorbing sticky substances and ensuring that the surface of the partition always remains clean, without affecting the uniform distribution of materials and the penetration efficiency of solvents.

[0016] In this invention, when new material is conveyed inside the partition, the operation of the tapping mechanism and the cleaning mechanism can vibrate and push the material held in the partition clamping area to mix it from both sides, so that the material is evenly distributed in the partition clamping area under the action of vibration, making the material uniformly loose. The back and forth movement of the scraper can push the material in contact with the partition surface to move, so that the material is in close contact with the partition surface to fill the gaps and avoid large gaps between the material and the partition that affect the leaching efficiency.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the invention and therefore only show the components relevant to the invention.

[0020] Reference Figures 1-10 As shown, the present invention provides a technical solution: a grain and oil production rotary extractor, including an extractor body 1, three spray devices 2 installed on one side of the extractor body 1, an extractor filter screen 3 fixedly connected to the middle of the inner wall of the extractor body 1, a rotating shell 4 rotatably connected to the middle of the extractor body 1, a plurality of partitions 5 fixedly connected to the surface of the rotating shell 4, and an outer circular plate 6 fixedly connected to one side of the plurality of partitions 5. The grain and oil production rotary extractor also includes a striking rod 7 and a scraper 8. A striking mechanism is installed on the inner wall of the partition 5. The cleaning mechanism is connected to the striking mechanism through a transmission, and the auxiliary mechanism is connected to the cleaning mechanism through a transmission. The protective mechanism is installed on the top of the partition 5.

[0021] Reference Figures 1-10 As shown in this embodiment, the striking mechanism includes: Motor 9, with a drive gear 10 mounted on its top output end. A support plate 11 is fixedly connected to the inner wall of partition 5. A transmission gear 12 is rotatably connected to the top of support plate 11 via a rotating shaft. A first gear 13 is fixedly connected to the top of transmission gear 12. A second gear 14 is rotatably connected to the top of support plate 11. A toothed chain 15 is meshed with the surface of the first gear 13. Two rotating rods 16 are rotatably connected to the middle of support plate 11. A third gear 17 is fixedly connected to the top of rotating rods 16, meshing with the inner wall of the toothed chain 15. The surface of the rotating rods 16... Two fourth gears 18 are fixedly connected to the surface of the partition 5. Two mounting brackets 19 are fixedly connected to the inner wall of the partition 5. Four central shafts 20 are fixedly connected to the top of the mounting brackets 19. A housing 21 is rotatably connected to the surface of the central shaft 20. One end of the striking rod 7 is fixedly connected to the surface of the housing 21. An inclined plate 22 is fixedly connected to one side of the housing 21. A first spring 23 is fixedly connected to one side of the housing 21. The other end of the first spring 23 is fixedly connected to the inner wall of the partition 5. A drive device 34 is installed on one side of the leaching body 1. A delivery pipe 35 is fixedly connected to the bottom of the leaching body 1. Material is poured into the leaching tank 1 through the feed inlet at the top, allowing it to flow into the rotating compartment formed by the baffle 5. The conveying pipe 35 then drives the rotating shell 4 and baffle 5 to slowly rotate at the top of the leaching filter 3. During this process, when the rotating compartment carrying the material reaches the bottom of the spraying device 2, it comes into contact with the solvent sprayed from the spraying device 2. Through this contact between the solvent and the material, the effective components in the material are fully extracted. Then, due to gravity, the oil and solvent mixture drips through the leaching filter 3 to the bottom area of ​​the leaching tank 1, and then through the conveying pipe 35... The leaching mixture is conveyed to the next step for processing and extraction separation. After the material and solvent are mixed and the oil is leached, the baffle 5 carrying the material will rotate to the opening of the leaching filter 3. At this time, the bottom of the material is no longer restricted by the leaching filter 3. The material in the baffle 5 can fall down through the opening of the leaching filter 3 to the conveying channel at the bottom of the leachator body 1. The conveying equipment then conveys the leached material to the subsequent steps for processing. After that, the baffle 5 continues to rotate counterclockwise. The above operation is only part of the principle of the existing flat rotary leachator operation process. When the partition 5 rotates to the opening of the leaching filter screen 3 and both sides of the opening, the motor 9 will run and drive the drive gear 10 to rotate clockwise. The drive gear 10 rotates the transmission gear 12 and the first gear 13 in the opposite direction. This causes the first gear 13 to rotate, driving the toothed chain 15 and the second gear 14 to rotate. At the same time, the third gear 17 will also rotate along with the toothed chain 15. The rotation of the third gear 17 drives the rotating rod 16 and the fourth gear 18 to rotate counterclockwise. When the fourth gear 18 rotates counterclockwise, it will contact one end of the inclined plate 22. When the fourth gear 18 rotates, the tooth groove pushes the inclined plate 22, causing the sleeve 21 to deflect slightly along the surface of the central axis 20. When the sleeve 21 rotates, it will compress the first spring 23 to contract. When the fourth gear 18 rotates to a certain angle and no longer contacts the inclined plate 22, the first spring 23 will rebound and push one side of the sleeve 21 to reset along the central axis 20. This causes the sleeve The rotation of 21 drives the striking rod 7 to approach the partition 5, realizing the striking rod 7 striking the partition 5. During the continuous operation of the motor 9, the rotating rod 16 will cause the striking rod 7 to repeat the above striking process, which will cause the partition 5 to vibrate due to the striking of the striking rod 7. At this time, the partition 5 will be on both sides or directly above the opening of the leaching filter screen 3. At this time, the material carried between the two partitions 5 has begun to fall down through the opening of the leaching filter screen 3, or the material has completely fallen and discharged from between the partitions 5. The vibration generated by the striking rod 7 on the partition 5 will cause the material adsorbed on the surface of the partition 5 to vibrate. Through the vibration effect, the adsorbed sticky substance on the surface of the partition 5 will fall off faster. When the partition 5 is at the opening of the leaching filter screen 3, if the material carried inside it expands and tightens due to mixing with the solvent, the vibration of the partition 5 will effectively promote the loosening of the material, avoiding the material from being unable to be discharged smoothly due to being tightly attached to the surface of the partition 5. Vibration is generated by striking the partitions 5 with the striking rod 7, which increases the efficiency of the material carried by the two partitions 5 being discharged downward through the opening of the leaching filter screen 3. This prevents some material from adsorbing onto the surface of the partitions 5 after the leaching process is completed, ensuring that the material is completely discharged, reducing residue, and improving leaching efficiency. In addition, when new material is introduced at the clamping point of the partitions 5, this vibration can promote the uniform distribution of the material between the partitions 5, thereby increasing the contact area between the material and the solvent and accelerating the leaching speed. Vibration also helps to prevent the material from forming clumps on the surface of the partitions 5, keeping the material in a loose state, so that the solvent can penetrate into the interior of the material more effectively, improving leaching efficiency, promoting the full leaching of the internal components of the material, improving the quality and yield of grain and oil products, thereby solving the problems of poor material discharge and residue, improving leaching efficiency and product quality, and bringing significant benefits to grain and oil production.

[0022] Reference Figure 5 , Figure 6 and Figure 7 As shown in this implementation plan, the cleaning mechanism includes: The U-shaped frame 24 has a long groove 25 at its top. A sliding rod 26 is slidably connected to the inner wall of the long groove 25. The bottom of the sliding rod 26 is fixedly connected to the toothed chain 15. The top of the inner wall of the partition 5 has a groove that matches the movement trajectory of the sliding rod 26. When the motor 9 drives the toothed chain 15 to rotate, the sliding rod 26 will rotate simultaneously with the toothed chain 15. As the sliding rod 26 rotates, it will adjust its position by sliding left and right within the inner wall of the long groove 25. When the sliding rod 26 moves back and forth a long distance on both sides of the third gear 17, it will drive the U-shaped frame 24 to move synchronously. As the U-shaped frame 24 moves repeatedly with the rotation of the toothed chain 15, it drives the scraper 8 to move back and forth synchronously. During this movement, because it is on the outside of the partition 5 and in contact with the surface of the partition 5, the scraper 8 will scrape during the movement. The sticky substances and material residues on the surface of the partition 5 are detached from the surface of the partition 5, and the centrifugal force generated by the back-and-forth movement of the scraper 8 completely removes these sticky substances and material residues from the surface of the partition 5, ensuring the cleanliness of the surface of the partition 5 and preventing stubborn dirt adsorbed on the surface of the partition 5 from being unable to fall off by gravity and affecting the subsequent leaching efficiency of new materials. This design not only improves the automated cleaning capability of the equipment, but also avoids the tediousness and inefficiency of manual cleaning, effectively extending the service life of the equipment. At the same time, the special material and design of the scraper 8 during the scraping process ensures that it will not damage the surface of the partition 5, maintaining the integrity of the equipment. In addition, when the device rotates to the inlet area to discharge materials, the motor 9 will also run to drive the scraper 8 to move repeatedly to promote the uniform distribution of materials between the partitions 5, further improving the leaching efficiency.

[0023] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in this embodiment, the auxiliary mechanism includes: Slider 27, four of which are evenly distributed on both sides of the U-shaped frame 24. Two wave grooves 28 are formed on both sides of the inner wall of the partition 5. The sliders 27 are slidably connected to the inner wall of the wave grooves 28. As the U-shaped frame 24 moves back and forth following the slide rod 26, the sliders 27 move in the same direction along the surface of the wave grooves 28. The wave-shaped feature of the inner wall structure of the wave grooves 28 causes the sliders 27 to move up and down repeatedly as they slide along the wave grooves 28. This causes the U-shaped frame 24 to move up and down repeatedly as it moves back and forth. Simultaneously, the long groove 25 moves along the surface of the slide rod 26. The upward and downward movement of the scraper 8 causes it to move slightly up and down on the surface of the partition 5 while scraping waste. The vibration generated by this process shakes off the residue that is stuck to the scraper 8. The scraper 8 moves up and down repeatedly as it resets on the surface of the partition 5, which increases the scraping force of the scraper 8 on the stubborn dirt on the surface of the partition 5. The sawing force generated by the repeated up and down movement increases the cutting force of the scraper 8 on the dirt, making it easier for the dirt to be scraped off by the scraper 8. This ensures the cleanliness of the surface of the partition 5 and avoids the impact of dirt residue on subsequent material leaching processing.

[0024] Reference Figure 5 , Figure 7 , Figure 8 and Figure 9 As shown in this implementation plan, the protective mechanism includes: Two baffles 29 are distributed on both sides of the top of the partition 5. Extension rods 32 are fixedly connected to both sides of each baffle 29. Two short grooves 31 are formed on both sides of the inner wall of the partition 5. The extension rods 32 are slidably connected to the inner walls of the short grooves 31. The top of the scraper 8 has a square structure, and an arc angle 33 is formed on one side of its bottom. The arc angle 33 is slidably connected to one end of the baffle 29. Several second springs 30 are fixedly connected inside the baffle 29. The tops of the second springs 30 are fixedly connected to the partition 5. When the scraper 8 moves back and forth on the surface of the partition 5 for cleaning, the arc angle 33 on one side of the scraper 8 will contact the inclined surface of the baffle 29. The scraper 8 is pushed forward and contacts the baffle 29. This causes the scraper 8 to push the baffle 29 upwards. As the scraper 8 continues to move forward, the baffle 29 will be positioned at the bottom of the scraper 8. When the baffle 29 rises, the extension rod 32 will also slide and rise along the short groove 31. This allows the baffle 29 to seal the sliding area of ​​the scraper 8 when the baffle 29 and the scraper 8 are in the initial position, thereby increasing the sealing of the top structure of the partition 5 and preventing material from entering the interior of the partition 5. When the scraper 8 pushes the baffle 29 upwards, it will also compress the second spring 30 to retract and store force. When the scraper 8 returns to the initial position, the second spring 30 will also rebound, causing the baffle 29 to move upwards to reset, so that the baffle 29 is in the forward area of ​​the scraper 8, sealing both sides of the top of the partition 5.

[0025] Reference Figure 7 As shown in this embodiment: the two sides of the U-shaped frame 24 are slidably connected to the two sides of the inner wall of the partition 5, and the surface of the scraper 8 is slidably connected to the outer surface of the partition 5. As the U-shaped frame 24 moves back and forth with the slide rod 26, the two sides of the U-shaped frame 24 and the scraper 8 will clamp the two sides of the partition 5 inside. The two sides of the U-shaped frame 24 and the scraper 8 form a U-shaped structure, which restricts the U-shaped frame 24 and the scraper 8 to the outer surface and inner wall surface of the partition 5, respectively, so as to ensure the tight contact between the scraper 8 and the surface of the partition 5, increase the contact area between the scraper 8 and the partition 5, and ensure the cleaning effect of the scraper 8 when it moves to the surface of the partition 5.
