Description

A perilla oil extraction device Technical Field

[0001] This invention belongs to the field of perilla oil extraction technology, and specifically relates to a perilla oil extraction device. Background Technology

[0002] Perilla oil, rich in high-quality unsaturated fatty acids such as alpha-linolenic acid, is experiencing a continuously rising demand in the health food, nutritional supplement, and cosmetic industries. Alpha-linolenic acid purification technology requires the prior extraction of perilla oil. Current perilla oil extraction methods primarily rely on pressing perilla seeds. After pressing, the oil and residue need to be separated to extract a purer perilla oil. In existing equipment, the residue cleaning mechanism is often independently designed, preventing simultaneous residue cleaning and oil filtration. Furthermore, even after filtration, a large amount of oil remains adsorbed in the residue, resulting in a 5%-10% reduction in perilla oil extraction rate and impacting extraction efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention aims to provide a perilla oil extraction device to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this perilla oil extraction device to solve its technical problem is as follows: A perilla oil extraction device is provided, including a tank body, a bracket fixedly installed on the tank body, a ball head fixedly installed on the bracket, the ball head being fitted into a ball seat, an outer cylinder connected to the ball seat through a connecting frame, a filter screen fixedly installed at the bottom of the outer cylinder, a through hole opened in the middle of the filter screen and a fixed inner cylinder installed thereon, a first motor provided at the bottom of the tank body, the output end of the first motor being connected to a rotating shaft through a reducer, the top end of the rotating shaft passing through the inner cylinder and fixedly connected to one end of a connecting rod, the other end of the connecting rod being fixedly connected to a residue scraping device, the residue scraping device being provided with a residue cleaning device, an oil inlet pipe fixedly installed on the connecting frame, and an oil outlet provided on one side of the tank body.

[0005] Furthermore, the residue scraping device includes a first scraper that contacts the filter screen. Support seats are fixedly installed on both sides of the first scraper. One of the support seats is fixedly connected to the rotating shaft through a connecting rod. A synchronous belt is provided on one side of the support seat. Two synchronous pulleys are respectively fitted inside the synchronous belt. One of the synchronous pulleys is driven by a second motor, and the other synchronous pulley is rotatably installed on the support seat. A screen is fixedly installed between the two synchronous belts.

[0006] Furthermore, the residue cleaning device includes a second scraper located on one side of the screen, with both sides of the second scraper fixedly mounted on the support base. A conveyor belt is provided below the second scraper, and the conveyor belt is fixedly mounted on the support base and driven by a third motor.

[0007] Furthermore, a sleeve is fixedly installed at the bottom of the tank, the sleeve is fitted over the outside of the rotating shaft, a spiral blade is fixedly installed on the rotating shaft, the discharge end of the conveyor belt is located above the sleeve, and a slag discharge port is provided at the bottom of the sleeve outside the tank.

[0008] Furthermore, a collection box is provided below the slag discharge port of the sleeve.

[0009] Furthermore, permeation holes are uniformly formed on the outer periphery of the casing.

[0010] Furthermore, a top rod is fixedly installed at the top of the rotating shaft, and a guide wheel is fixedly installed on the top rod, with the outer circumference of the guide wheel contacting the inner wall of the inner cylinder.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the perilla oil extraction device exemplified by the present invention, the pressed perilla oil enters the filter screen through the oil inlet pipe for filtration, and the perilla seed residue is filtered onto the filter screen. The first motor is started, and the residue scraping device is rotated through the rotating shaft to scrape off the residue on the filter screen. The scraped residue is then cleaned by the residue cleaning device. With this device, perilla oil can be easily filtered, and the residue can be easily cleaned after filtration, thereby improving the extraction rate of perilla oil.

[0012] 2. An example of the perilla oil extraction device of the present invention uses a first scraper to scrape off the residue on the filter screen and shovel the residue onto the screen. The screen is moved by a synchronous belt, thereby transferring the residue. During the movement of the screen, the impact between the screen and the perilla oil forces the perilla oil to move backward in the direction of movement, i.e., in the direction of scraping off the residue. This can dilute the residue content in the local area behind the moving direction, and enable the scraped area to be filtered more quickly.

[0013] 3. An example of the perilla oil extraction device of the present invention uses a second scraper to scrape the residue on the screen onto the conveyor belt for removal.

[0014] 4. An example of the perilla oil extraction device of the present invention uses spiral blades to conveniently guide the residue downwards to the slag discharge port for discharge.

[0015] 5. An example of the perilla oil extraction device of the present invention, which can conveniently collect residue through a collection box.

[0016] 6. An example of the present invention is a perilla oil extraction device, which allows oil in the waste residue to easily seep out into the tank when the waste residue is discharged through a permeation hole.

[0017] 7. An example of the perilla oil extraction device of the present invention can push the outer cylinder, filter screen and inner cylinder to always tilt through the top rod and guide wheel, so that the tilted downward part is always below the first scraper, which facilitates the oil to be collected in the area where the residue has been scraped off, and at the same time facilitates the high-level residue to settle on the top surface of the filter screen when the oil flows away.

A bracket 2 is fixedly installed on the tank body 1, and a ball head 3 is fixedly installed on the bracket 2. The ball head 3 is fitted into a ball seat 4. An outer cylinder 6 is connected to the ball seat 4 through a connecting frame 5. A filter screen 7 is fixedly installed at the bottom of the outer cylinder 6. A through hole is opened in the middle of the filter screen 7 and an inner cylinder 8 is fixedly installed thereon. A first motor 9 is provided at the bottom of the tank body 1. The output end of the first motor 9 is connected to a rotating shaft 10 through a reducer. The top end of the rotating shaft 10 passes through the inner cylinder 8 and is fixedly connected to one end of a connecting rod 11. The other end of the connecting rod 11 is fixedly connected to a residue scraping device. The residue scraping device is equipped with a residue cleaning device. An oil inlet pipe 12 is fixedly installed on the connecting frame 5. An oil outlet 13 is provided on one side of the tank body 1.

[0023] In this embodiment, the residue scraping device includes a first scraper 14 that contacts the filter screen 7. Support seats 15 are fixedly installed on both sides of the first scraper 14. One of the support seats 15 is fixedly connected to the rotating shaft 10 through a connecting rod 11. A synchronous belt 16 is provided on one side of the support seat 15. Two synchronous pulleys 17 are respectively fitted inside the synchronous belt 16. One of the synchronous pulleys 17 is driven by a second motor 18, and the other synchronous pulley 17 is rotatably installed on the support seat 15. A screen 19 is fixedly installed between the two synchronous belts 16.

[0024] In this embodiment, the residue cleaning device includes a second scraper 20 located on one side of the screen 19. The two sides of the second scraper 20 are respectively fixedly installed on the support base 15. A conveyor belt 21 is provided below the second scraper 20. The conveyor belt 21 is fixedly installed on the support base 15 and driven by a third motor 22.

[0025] In this embodiment, a sleeve 23 is fixedly installed at the bottom of the tank body 1. The sleeve 23 is fitted onto the outside of the rotating shaft 10. A spiral blade 24 is fixedly installed on the rotating shaft 10. The discharge end of the conveyor belt 21 is located above the sleeve 23. The bottom of the sleeve 23 outside the tank body 1 is provided with a slag discharge port.

[0026] In this embodiment, a collection box is provided below the slag discharge port of the sleeve 23.

[0027] In this embodiment, the outer periphery of the sleeve 23 is uniformly provided with permeation holes, specifically, the pore diameter of the permeation holes is 50-100μm.

[0028] In this embodiment, a top rod 25 is fixedly installed at the top end of the rotating shaft 10, and a guide wheel 26 is fixedly installed on the top rod 25. The outer periphery of the guide wheel 26 contacts the inner wall of the inner cylinder 8.

[0029] Supported by the top rod 25 and the guide wheel 26, the outer cylinder 6, filter screen 7, and inner cylinder 8 are always tilted, with the downward tilted portion always located below the first scraper 14. During use, the extracted perilla oil enters the filter screen 7 through the oil inlet pipe 12 for filtration, filtering the perilla seed residue onto the filter screen 7. The first motor 9 is started, and the rotating shaft 10 drives the support base 15 and the first scraper 14 to move along the surface of the filter screen 7, scraping the residue onto the screen 19 through the first scraper 14. As the screen 19 moves with the synchronous belt 16, the residue on the screen 19... The oil in the residue is drained off, and the remaining residue is scraped onto the conveyor belt 21 by the second scraper 20 and guided into the sleeve 23. After being guided by the spiral blades 24, it is discharged from the slag discharge port, at which point the waste residue can be collected. Through this device, by utilizing the cooperation between the ball head and the ball seat, combined with the support of the push rod and the guide wheel for the inner cylinder, the filter screen can always be kept in an inclined state, so that the oil can always naturally gather towards the residue-free area during the filtration process. It also promotes the sedimentation of high-position residues in the shallow layer under the action of the oil flow, and the high-position residues are filtered through the filter screen 7. The inclined posture and the flow of perilla oil allow it to naturally converge towards the center, preventing residue from accumulating at the edges of the outer cylinder 6 and filter screen 7 and affecting the cleaning effect. This significantly improves filtration efficiency and the utilization rate of filter screen 7. Furthermore, the inclined posture allows the outer cylinder 6 to bear some of the pressure from the perilla oil, reducing the pressure on filter screen 7 and extending its service life. Simultaneously, as the screen 19 moves, it forces the stationary perilla oil to move with it. During this movement, the resistance of the perilla oil on the surface of the screen 19 increases its osmotic pressure, causing some of the perilla oil to pass through the screen holes and enter the rear of the moving direction, moving towards the direction where the residue has been scraped off. This dilutes the residue content in the rear of the moving direction. The reduced residue content, combined with the freshly cleaned filter screen 7, allows the perilla oil to pass through the mesh of the filter screen 7 more quickly, improving filtration efficiency. Moreover, during residue collection, the permeation holes on the sleeve enable secondary oil recovery, reducing the oil content in the residue, minimizing oil waste, and increasing the extraction rate of perilla oil.
