Description

Technical Field

[0001] This utility model relates to the field of milk thistle processing technology, and more specifically, to a sieve iron removal device for milk thistle processing. Background Technology

[0002] Milk thistle is a natural plant that protects the liver, helping the body eliminate toxins and reduce inflammation. Its main function is to enhance the liver's detoxification ability and improve problems such as yellowing skin, right upper abdominal bloating, and poor appetite caused by long-term sleep deprivation, alcohol consumption, or irregular eating habits. However, iron filings may be introduced during the washing and impurity removal processes, affecting subsequent processing. Therefore, it is necessary to sieve the milk thistle to remove iron.

[0003] Utility model patent CN221832835U discloses a high-efficiency iron removal screening machine, including a mounting frame. An auxiliary screening component is located at the top of the mounting frame, and an iron filings adsorption component is located at the bottom. The iron filings adsorption component includes crossbeams fixedly connected between support blocks of the mounting frame. An electromagnet is fixedly installed between two crossbeams, and a triangular rib is fixedly connected to the top of the electromagnet. A guide trough is fixedly connected to the inner wall of the mounting frame, and a discharge hole is also provided inside the mounting frame. This application utilizes an electromagnet to generate a strong metallic attraction when energized. When the raw material being filtered initially falls through the guide trough, it can adsorb and separate small iron filings mixed in. However, the above patent has the following shortcomings: the electromagnet can only remove iron from screened medicinal materials, making it inconvenient to remove iron from unscreened medicinal materials, resulting in poor practicality; furthermore, the iron filings on the electromagnet are not easily removed automatically. Therefore, we propose a sieve-based iron removal device for milk thistle processing. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a sieve iron removal device for milk thistle processing.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A sieving and iron removal device for processing milk thistle includes a frame with a sieving mechanism.

[0008] As a preferred embodiment of this utility model, the screening mechanism includes a screening box fixedly sleeved on the frame and a hopper fixedly connected to the bottom of the frame. A screening cylinder is rotatably connected to the screening box. Multiple screen holes are opened on the side of the screening cylinder and in the inner cavity of the screening box. The end of the feed chute extends into the inner cavity of the screening cylinder. A second gear is fixedly sleeved on the outer side of the screening cylinder. A fourth motor is fixedly installed on the end face of the screening box. A first gear is fixedly sleeved on the output shaft of the fourth motor. The first gear and the second gear mesh with each other.

[0009] As a preferred embodiment of this utility model, a control panel is fixedly installed on the side of the screening box, and a sealing plate is hinged to the top of the screening box.

[0010] In a preferred embodiment of this utility model, the two sides of the conveyor belt are respectively attached to the inner wall of the feed trough.

[0011] In a preferred embodiment of this utility model, one side of the annular magnet is located above the feed trough, and the other side of the annular magnet is located above the U-shaped scraper.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) In this utility model, the first motor drives the transmission roller and the conveyor belt to rotate, the conveyor belt feeds the milk thistle raw material to be screened, and the ring magnet adsorbs the iron filings mixed in the milk thistle raw material. In addition, the third motor drives the push rod to rotate and push the upper part of the conveyor belt, so that the milk thistle raw material on the conveyor belt is turned over, ensuring that the iron filings at the bottom are turned up, and ensuring that the ring magnet completely adsorbs and removes the iron filings, thus realizing the function of completely removing the iron filings in the milk thistle raw material before screening.

[0014] (2) In this utility model, the second motor drives the turntable and the ring magnet to rotate slowly. When the ring magnet adsorbs iron filings above the conveyor belt, the rotating ring magnet drives the iron filings to the front of the U-shaped scraper. The U-shaped scraper scrapes and cleans the iron filings below the ring magnet. The scraped iron filings slide into the inner cavity of the receiving box through the U-shaped scraper and are collected, thus realizing the function of automatically cleaning the adsorbed iron filings.

[0026] Please see Figures 1-5 A sieve for removing iron during milk thistle processing includes a frame 1, a screening mechanism 2 mounted on the frame 1, multiple support columns 3 fixedly connected to the top surface of the frame 1, a feed trough 4 fixedly connected to the top of the support columns 3, two drive rollers 5 rotatably connected to the inner cavity of the feed trough 4, a conveyor belt 6 drivingly connecting the two drive rollers 5, a first motor 7 fixedly mounted on the side of the feed trough 4, the output shaft of the first motor 7 connected to one end of the shaft of one drive roller 5, and multiple pushing mechanisms 8 mounted on the feed trough 4. A mounting base 9 is fixedly connected to the side of the feed trough 4. A second motor 10 is fixedly installed on the bottom surface of the mounting base 9. The output shaft of the second motor 10 extends to the top of the mounting base 9 and is fixedly connected to a turntable 11. A ring magnet 12 is fixedly connected to the bottom surface of the turntable 11. A support rod 13 is fixedly connected to the side of the feed trough 4. A U-shaped scraper 14 is fixedly connected to the side of the support rod 13. The top of the U-shaped scraper 14 is in contact with the bottom surface of the ring magnet 12. A receiving box 15 is placed on the top surface of the frame 1 and below the U-shaped scraper 14.

[0027] For details, please refer to Figure 3 and Figure 5 The pushing mechanism 8 includes a rotating rod 17 rotatably connected to the inner cavity of the feed trough 4 and a third motor 16 fixedly installed on the side of the feed trough 4. The output shaft of the third motor 16 is connected to the end of the rotating rod 17. The rotating rod 17 passes through the inner side of the conveyor belt 6, and multiple push rods 18 are fixedly connected to the side of the rotating rod 17.

[0028] In this embodiment, the third motor 16 drives the rotating rod 17 and the push rod 18 to rotate. The push rod 18 pushes the conveyor belt 6 to vibrate up and down, causing the milk thistle raw material on the conveyor belt 6 to turn over, ensuring that the iron filings in the milk thistle raw material are effectively removed.

[0029] For details, please refer to Figure 1 and Figure 4 The screening mechanism 2 includes a screening box 19 fixedly sleeved on the frame 1 and a hopper 20 fixedly connected to the bottom of the frame 1. A screening cylinder 21 is rotatably connected to the screening box 19. Multiple screen holes 22 are opened on the side of the screening cylinder 21 and in the inner cavity of the screening box 19. The end of the feed chute 4 extends into the inner cavity of the screening cylinder 21. A second gear 26 is fixedly sleeved on the outer side of the screening cylinder 21. A fourth motor 24 is fixedly installed on the end face of the screening box 19. A first gear 25 is fixedly sleeved on the output shaft of the fourth motor 24. The first gear 25 and the second gear 26 mesh with each other.

[0030] In this embodiment, bearings are fixedly sleeved at both ends of the screening box 19, and the screening cylinder 21 is fixedly sleeved on the inner side of the two bearings. In addition, the bottom end of the screening cylinder 21 extends to the side of the frame 1 so as to discharge the unscreened material and receive the material using an external receiving box.

[0031] For details, please refer to Figure 1 A control panel 27 is fixedly installed on the side of the screening box 19, and a sealing plate 23 is hinged to the top of the screening box 19.

[0032] In this embodiment, the device is controlled using the control panel 27.

[0033] For details, please refer to Figure 1 and Figure 2 The two sides of the conveyor belt 6 are respectively attached to the inner wall of the feed trough 4.

[0034] In this embodiment, the inner wall of the feed trough 4 is used to limit the side of the conveyor belt 6 to prevent milk thistle from falling off the side of the conveyor belt 6.

[0035] For details, please refer to Figure 1 and Figure 4 One side of the annular magnet 12 is located above the feed trough 4, and the other side of the annular magnet 12 is located above the U-shaped scraper 14.

[0036] In this embodiment, when the annular magnet 12 moves above the feed trough 4, the magnetic force of the annular magnet 12 can be used to adsorb and clean the iron filings mixed in with the milk thistle on the conveyor belt 6. In addition, the U-shaped scraper 14 can be used to scrape off the iron filings adsorbed on the annular magnet 12.

[0037] Working principle: In operation, the first motor 7 is started, driving a transmission roller 5 to rotate clockwise. The transmission roller 5 then drives the conveyor belt 6 to rotate clockwise. Simultaneously, multiple third motors 16 are started, driving multiple rotating rods 17 and multiple push rods 18 to rotate. The push rods 18 push the top of the conveyor belt 6, causing it to vibrate. The milk thistle material to be screened and de-ironized is then placed on the conveyor belt 6. The conveyor belt 6 transports the milk thistle material, and the vibration of the conveyor belt 6 causes the material to tumble. During this tumbling process, the ring magnet 12 attracts iron filings mixed in with the milk thistle material, thus removing the iron filings. Then, the second motor 10 is started to drive the turntable 11 and the ring magnet 12 to rotate slowly counterclockwise. The iron filings adsorbed on the bottom surface of the ring magnet 12 are scraped off by the U-shaped scraper 14 and guided into the receiving box 15 for collection. Finally, the fourth motor 24 is started to drive the first gear 25 to rotate. The meshing transmission between the first gear 25 and the second gear 26 drives the screening cylinder 21 to rotate, so as to screen the milk thistle raw material conveyed from the conveyor belt 6 to the inner cavity of the screening cylinder 21. The milk thistle raw material that meets the size is screened through the screen hole 22 and discharged from the discharge hopper 20. The milk thistle raw material that does not meet the size is discharged from the bottom of the screening cylinder 21.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
