[0002] In the process of artemisinin extraction, fine sand is widely used in the impurity removal step as an important auxiliary material. However, the size of fine sand has a certain influence on the impurity removal effect of artemisinin extraction. Smaller fine sand particles have a larger specific surface area, which means that they can adsorb more impurities, especially some fine suspended matter or particles. Larger fine sand particles have lower filtration efficiency because of their smaller specific surface area and cannot effectively adsorb and remove fine impurities. At the same time, the pores of large-size fine sand are relatively large, which may cause some larger impurities to be missed.

[0024] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0025] Please refer to Figure 1-Figure 5 As shown, a fine sand supply device for artemisinin extraction and impurity removal includes a sand box 1 and a lower hopper 102. A collecting mechanism 3 is installed at the lower end of the sand box 1. The collecting mechanism 3 includes a mounting frame 301. The mounting frame 301 is fixedly connected to the lower end of the sand box 1. The lower hopper 102 is fixedly connected to the lower end of the mounting frame 301. A connecting pipe 103 is fixedly connected to the lower end of the lower hopper 102. A blower 101 is fixedly installed at one end of the connecting pipe 103. A conveying pipe 104 is fixedly connected to the other end of the connecting pipe 103. A screening mechanism 2 is installed inside and outside the sand box 1. The screening mechanism 2 includes a screening box 202. The screening box 202 is installed inside the sand box 1. A flipping mechanism 4 is installed outside the sand box 1.

[0026] In this solution, the fine sand supply device is mainly used for the impurity removal step in the artemisinin extraction process. The upper end of the delivery pipe 104 is connected to the artemisinin extraction device. The sandbox 1 is the main part, which stores fine sand and realizes the transportation of fine sand through a series of structures including the lower hopper 102, the connecting pipe 103, the blower 101 and the delivery pipe 104. The blower 101 provides power to transport the fine sand to the artemisinin extraction device through the delivery pipe 104.

[0027] Furthermore, the screening mechanism 2 screens the fine sand by reciprocating the screening box 202. The bottom surface of the screening box 202 is provided with a screen, which can remove large particles of impurities in the sand and sand particles that do not meet the requirements, thereby improving the purity of the fine sand and helping to improve the impurity removal effect during the extraction of artemisinin.

[0028] Furthermore, the flipping mechanism 4 drives the screening box 202 to rotate and flip, so that the impurities inside the screening box 202 fall down;

[0029] Furthermore, the collecting mechanism 3 can collect and clean large particles of sand and impurities.

[0030] Please refer to Figure 2-Figure 3 As shown, the outer side of the screening box 202 is fixedly connected with a first guide rod 201 and a second guide rod 208, respectively. The first guide rod 201 and the second guide rod 208 are mirror-imaged on the outer side of the screening box 202, and the outer side of the second guide rod 208 is fixedly connected with two sets of limit rods 209. The first guide rod 201, the second guide rod 208 and the limit rod 209 are all slidably connected to the sand box 1.

[0031] The screening mechanism 2 also includes a driving motor 203, which is installed on the outside of the sand box 1 through a horizontal plate. The output end of the driving motor 203 is fixedly connected to a driving rod 204, and a connecting rod 205 is hinged at the end of the driving rod 204. The end of the connecting rod 205 away from the driving rod 204 is hinged to a mounting seat 206, and the outer side of the mounting seat 206 is fixedly connected to a first bearing seat 207, and one end of the first guide rod 201 is rotatably connected to the inside of the first bearing seat 207.

[0032] Furthermore, the driving motor 203 is electrically connected to an external power supply, and the driving motor 203 drives the driving rod 204 to rotate. The driving rod 204 drives the first guide rod 201 (and the screening box 202 connected thereto) to perform reciprocating motion through the connecting rod 205 and the mounting seat 206 to realize the screening function. The second guide rod 208 and the limit rod 209 serve as guiding and limiting structures to ensure that the screening box 202 moves stably in the sand box 1, so that small particles of fine sand automatically fall into the lower hopper 102 for transportation, thereby providing better quality impurity-removing raw materials for the extraction of artemisinin.

[0033] Please refer to Figure 4 As shown, the flipping mechanism 4 includes a limiting sleeve 403 and a second bearing seat 405. The second bearing seat 405 is fixedly connected to the outside of the sand box 1. The limiting sleeve 403 is rotatably connected to the inside of the second bearing seat 405. The second guide rod 208 and the limiting rod 209 are both slidably connected to the limiting sleeve 403. The outside of the limiting sleeve 403 is fixedly connected with a gear ring 404.

[0034] The flipping mechanism 4 also includes a second electric push rod 401 , which is installed on the outside of the sandbox 1 through a transverse plate. The output end of the second electric push rod 401 is fixedly connected to a toothed plate 402 , which is meshed with a toothed ring 404 .

[0035] Furthermore, the second electric push rod 401 is electrically connected to an external power supply, and the second electric push rod 401 can drive the tooth plate 402 to move, and the tooth plate 402 is meshed with the gear ring 404, thereby driving the limiting sleeve 403 (and the second guide rod 208 and the screening box 202 connected thereto) to flip, so that the screening box 202 automatically flips after the screening is completed, which is convenient for automatically cleaning the impurities and large sand particles inside the screening box 202, and simplifies the cleaning process of the screening box 202;

[0036] Furthermore, the limiting rod 209 can make the second guide rod 208 only slide inside the limiting sleeve 403 , and at the same time, the limiting sleeve 403 can drive the second guide rod 208 to rotate under the limitation of the limiting rod 209 .

[0037] Please refer to Figure 5 As shown, the collection box 303 is slidably connected inside the installation frame 301, and the first electric push rod 302 is installed on the outside of the installation frame 301. The output end of the first electric push rod 302 is fixedly connected to a connecting plate 304, and the end of the connecting plate 304 is fixedly connected to the collection box 303.

[0038] Furthermore, when it is necessary to clean the inside of the screening box 202, the first electric push rod 302 drives the connecting plate 304 and the collecting box 303 to slide to the inside of the installation frame 301. At this time, the screening box 202 flips over to dump impurities, thereby collecting fine sand that falls from the screening box 202 to achieve automatic cleaning. After cleaning, the collecting box 303 can be moved to the outside of the installation frame 301 and reset to ensure normal supply of fine sand.

[0039] A feed hopper 105 is installed at the upper end of the sandbox 1. The feed hopper 105 serves as the top opening of the sandbox 1 and is used to add fine sand into the sandbox 1. The fine sand enters the sandbox 1 through the feed hopper 105 and is screened under the action of the screening mechanism 2.

[0040] The working principle and use process of the present invention are as follows: first, fine sand is added into the sand box 1 through the feed hopper 105, and the sand falls into the interior of the screening box 202, and the drive motor 203 is started. The drive motor 203 drives the first guide rod 201 to reciprocate through the drive rod 204, the connecting rod 205 and the mounting seat 206, and drives the screening box 202 to reciprocate to screen the fine sand, and screens out small particles of fine sand, which automatically fall into the lower hopper 102, and large particles of impurities and sand that do not meet the requirements are left in the screening box 202, and at the same time, the blower 101 is started, and the blower 101 provides power to make the small particles of fine sand that pass the screening pass through the connecting pipe 103 and the conveying pipe 1 04 is transported to the artemisinin extraction equipment. When a certain amount of impurities and large sand particles have accumulated in the screening box 202 and need to be cleaned, the second electric push rod 401 is started, and the second electric push rod 401 drives the tooth plate 402 to move, and the tooth plate 402 engages with the gear ring 404, thereby driving the limiting sleeve 403 to flip, and then drives the screening box 202 to flip, and the impurities and large sand particles inside are poured out. At the same time, the first electric push rod 302 is started and drives the connecting plate 304 and the collecting box 303 to slide to the inside of the installation frame 301, so that the collecting box 303 receives the fine sand dropped from the screening box 202, thereby realizing automatic cleaning.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
