Description

Technical Field

[0001] This utility model relates to the field of feeding technology, specifically a feeding device for extracting paclitaxel from yew branches and leaves. Background Technology

[0002] The yew tree has excellent medicinal value, mainly in its use for extracting the anticancer drug paclitaxel. Paclitaxel has the effect of inhibiting tumor growth and is a globally recognized broad-spectrum and highly active anticancer drug. Due to its unique mechanism of action and significant efficacy, paclitaxel has been increasingly widely used in the clinical treatment of lung cancer, ovarian cancer, and breast cancer. Paclitaxel resources are scarce and expensive, making its efficient extraction a key focus of research in the pharmaceutical industry. Currently, paclitaxel is mainly extracted from yew plant raw materials. The common method for extracting paclitaxel from yew plant raw materials is to first obtain crude paclitaxel through steps such as crushing, soaking, extracting, concentrating, and extracting the raw materials, and then purifying the crude paclitaxel using column chromatography to obtain high-purity paclitaxel.

[0003] Upon investigation, a Chinese utility model patent discloses a feeding device for extracting paclitaxel from yew branches and leaves (publication number: CN204124830U), which includes a feeding hopper (7), a vacuum suction pipe (10), a support (1), a sieving device, and a stirring device; the sieving device includes a sieve basket (2) with sieve holes (3), a hanging chain (4), and a vibration mechanism (5); the stirring device includes a motor (6), a stirring shaft (9), a middle stirring blade (8), and a bottom stirring blade (11).

[0004] In the aforementioned patent, after the pulverized yew branches and leaves are fed into the sieve basket, the pulverized yew branches and leaves are screened under the action of the vibration mechanism. However, the sieve basket adopts an inclined design. In actual use, some pulverized materials that meet the fineness requirements may not have time to fall from the sieve holes into the feeding hopper before they move quickly to the lower end of the sieve basket and slide out due to the vibration. This results in the failure to effectively separate qualified pulverized materials from unqualified pulverized materials, affecting the overall screening effect.

[0005] Therefore, this utility model provides a feeding device for extracting paclitaxel from yew branches and leaves to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a feeding device for extracting paclitaxel from yew branches and leaves, such as... Figure 1 , Figure 3 and Figure 5 As shown, the device includes a working plate 1, a support column 2 and a first bracket 4 fixedly connected to the top of the working plate 1, a support plate 3 fixedly connected to the top of the support column 2, a second bracket 5 fixedly connected to the top of the support plate 3, a first rotating shaft 6 rotatably connected to the first bracket 4 and the second bracket 5, a number of connecting rods 7 fixedly connected to the side surface of the first rotating shaft 6, and a screening cylinder 8 fixedly connected to the end of the number of connecting rods 7 away from the first rotating shaft 6, and a number of screening holes opened on the screening cylinder 8.

[0026] Multiple baffles 11 are fixedly connected inside the screening cylinder 8, and a baffle 12 is rotatably connected to the side surface of the first rotating shaft 6. One side of the baffle 12 is in contact with one end of the screening cylinder 8.

[0027] The top of the support plate 3 is fixedly connected to the first motor 13, and the output end of the first motor 13 is fixedly connected to one end of the first rotating shaft 6.

[0028] A support rod 14 is fixedly connected to the top of the support plate 3, and a feed hopper 15 is fixedly connected to the top of the support rod 14. The bottom end of the feed hopper 15 extends into the interior of the screening cylinder 8.

[0029] When the first motor 13 is working, it can directly drive the first rotating shaft 6. The first support 4 and the second support 5 provide a guarantee for the stable rotation of the first rotating shaft 6. The first rotating shaft 6 is connected to the screening cylinder 8 through the connecting rod 7, so the screening cylinder 8 will also rotate when the first rotating shaft 6 rotates.

[0030] When the yew branch and leaf powder is fed into the screening cylinder 8, the first motor 13 can be started. At this time, the screening cylinder 8 will rotate to screen the yew branch and leaf powder. The yew branch and leaf powder that meets the fineness requirements can fall through the screening holes. The screening cylinder 8 is set at an inclination, and the yew branch and leaf powder that does not meet the fineness requirements will fall from the bottom of the screening cylinder 8.

[0031] The baffle 12 reduces the possibility of spillage when the yew branch and leaf crushed material is fed into the screening cylinder 8. During the movement of the yew branch and leaf crushed material inside the screening cylinder 8, it will come into contact with the baffle 11, thereby slowing down the movement speed of the yew branch and leaf crushed material and effectively improving the screening effect of the screening cylinder 8.

[0032] It should be noted that, in order to reduce the workload of staff, such as Figure 1 , Figure 2 and Figure 4 As shown, the working plate 1 is provided with a first drop trough 9 and a second drop trough 10. The first drop trough 9 is located below the screening cylinder 8. A feeding hopper 16 is fixedly connected inside the first drop trough 9. A vacuum suction pipe 17 is fixedly connected to the bottom of the feeding hopper 16. The vacuum suction pipe 17 is connected to the inner cavity of the feeding hopper 16.

[0033] A second motor 18 is fixedly connected to the bottom of the working plate 1. A second rotating shaft 19 is fixedly connected to the output end of the second motor 18. The second rotating shaft 19 passes through the feeding hopper 16. Several stirring rods 20 are fixedly connected to the side surface of the second rotating shaft 19.

[0034] After the yew branch and leaf powder is fed into the screening cylinder 8, the screening cylinder 8 will screen the yew branch and leaf powder. The yew branch and leaf powder that meets the fineness requirements can fall into the feeding hopper 16 through the screening holes. The vacuum suction pipe 17 can pump the yew branch and leaf powder in the feeding hopper 16 to the extraction workshop for extraction, realizing mechanized automatic feeding to replace manual handling, thereby effectively reducing labor intensity, simplifying operation procedures, and improving work efficiency. The second drop trough 10 is located below the bottom of the screening cylinder 8. The staff can place a collection box at the second drop trough 10. The yew branch and leaf powder that does not meet the fineness requirements will fall from the bottom of the screening cylinder 8 into the collection box, so as to facilitate the staff to handle it.

[0035] After the yew branch and leaf pulverized material enters the inside of the feeding hopper 16, the second motor 18 can be started. When the second motor 18 is working, its output end can directly drive the second rotating shaft 19 to rotate. When the second rotating shaft 19 rotates, it can drive the stirring rod 20 to rotate, thereby stirring the yew branch and leaf pulverized material and effectively reducing the possibility of some yew branch and leaf pulverized material remaining inside the feeding hopper 16.

[0036] When using this device, the crushed yew branches and leaves need to be fed into the feed hopper 15. While the feed hopper 15 feeds the crushed yew branches and leaves into the screening cylinder 8, the first motor 13 is started. The first motor 13 drives the screening cylinder 8 to rotate through the first rotating shaft 6 and the connecting rod 7, thereby screening the crushed yew branches and leaves. The crushed yew branches and leaves that meet the fineness requirements can fall into the feeding hopper 16 through the screening holes. The vacuum suction pipe 17 can pump the crushed yew branches and leaves in the feeding hopper 16 to the extraction workshop for extraction. The screening cylinder 8 is set at an inclination, and the crushed yew branches and leaves that do not meet the fineness requirements will fall from the bottom of the screening cylinder 8.

[0037] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
