Abstract
Description
Technical Field
[0001] This utility model relates to the field of dried osmanthus processing technology, and in particular to a device for screening and removing impurities from dried osmanthus. Background Technology
[0002] Osmanthus is one of China's ten traditional famous flowers. It is an excellent garden tree species that combines greening, beautification, and fragrance, making it both ornamental and practical. Osmanthus is delicate and refreshing, and its fragrance can travel far and wide, making it truly unique. Especially in mid-autumn, when osmanthus trees are in full bloom, on a quiet night with the moon full, one can enjoy wine while admiring the osmanthus, and the rich fragrance will refresh the mind and body.
[0003] Fresh osmanthus flowers are small and difficult to pick by hand. They are usually knocked down with wooden sticks or bamboo poles. As a result, the harvested fresh osmanthus flowers contain a large number of foreign objects such as osmanthus branches and leaves.
[0004] After the osmanthus flowers are dried, foreign objects such as branches and leaves are still present in the dried flowers. Because these foreign objects vary in weight, volume and size, they are difficult to pick out directly from the dried osmanthus flowers, whether by manual selection or by vibration sorting. Utility Model Content
[0005] The purpose of this invention is to provide a dried osmanthus flower screening and impurity removal device, which can screen and remove impurities from untreated dried osmanthus flowers containing a large number of impurities, so as to obtain dried osmanthus flower raw materials that are free of impurities and of extremely high quality.
[0006] The objective of this utility model is achieved through the following technical solution:
[0007] A device for screening and removing impurities from dried osmanthus flowers includes an air separation assembly and a vibrating screening assembly arranged sequentially. The air separation assembly includes an air separation box, a first partition and a second partition disposed within the air separation box, a feed hopper disposed at the top of the air separation box, and a blower connected to the air separation box. The first partition and the second partition divide the air separation box into a light impurity collection chamber, a dried osmanthus flower collection chamber, and a heavy impurity collection chamber in sequence. The feed hopper is disposed directly above the heavy impurity collection chamber. The upper middle part of the second partition is provided with multiple filter holes.
[0008] Preferably, the filter holes on the second partition are 10 mesh.
[0009] Preferably, the first partition is movably disposed inside the air separator; the two opposite inner walls of the air separator are provided with a plurality of U-shaped grooves for placing the first partition.
[0010] Preferably, the bottom end of the first partition is magnetically connected to the bottom wall of the air separator.
[0011] Preferably, the vibrating screening assembly includes multiple support columns, a spring disposed at the top of the support columns, a screening box disposed at the top of the spring, a vibrating motor disposed on the screening box, and a first screen and a second screen disposed sequentially from top to bottom inside the screening box, wherein the aperture of the first screen is larger than the aperture of the second screen.
[0012] Preferably, the first screen is a 4-mesh screen; the second screen is a 20-mesh screen.
[0013] Preferably, the side wall of the screening box is provided with a second discharge port and a third discharge port, the second discharge port is located above the first screen, and the third discharge port is located between the first screen and the second screen.
[0014] Preferably, the first screen and the second screen are respectively inclined downward along the direction of the second discharge port and the third discharge port.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] By setting up an air separation assembly including an air separator, a first partition, a second partition, a feed hopper, and a blower, the dried osmanthus flowers containing a large number of impurities can be initially separated. Specifically, the blower separates the initially dried osmanthus flowers by air separation. Under the action of the wind, most of the heavy impurities in the dried osmanthus flowers (such as osmanthus branches, leaves, stones, and other foreign objects) can fall into the heavy impurity collection bin, while the light impurities (osmanthus leaf fragments, fibers, dust, etc.) can fall into the light impurity collection bin. The initially separated dried osmanthus flowers fall into the dried osmanthus flower collection bin.
[0017] By setting up a vibration screening component, the dried osmanthus flowers that have fallen into the dried osmanthus flower collection bin and undergone preliminary separation can be vibrated and screened again to further remove impurities from the dried osmanthus flowers and further improve the purity and quality of the dried osmanthus flowers.

Detailed Implementation
[0023] Example 1
[0024] A device for screening and removing impurities from dried osmanthus flowers, such as Figure 1 As shown, it includes an air separation assembly and a vibrating screening assembly arranged in sequence; the air separation assembly includes an air separation box 1, a first partition 2 and a second partition 3 disposed within the air separation box 1, a feed hopper 4 disposed at the top of the air separation box 1, and a blower 5 connected to the air separation box 1, as shown. Figure 1 and Figure 2 As shown, the blower 5 and the air classifier 1 are connected by an air duct. To increase the air classification area of the material, a horn-shaped hood can be installed at the air outlet of the air duct during actual screening. The first partition 2 and the second partition 3 divide the air classifier 1 into a light impurity collection chamber 6, a dried osmanthus flower collection chamber 7, and a heavy impurity collection chamber 8. The feed hopper 4 is located directly above the heavy impurity collection chamber 8, and the air outlet of the air duct is located on the side wall of the heavy impurity collection chamber 8. The upper middle part of the second partition 3 is provided with multiple filter holes, specifically, the filter holes on the second partition 3 are 10 mesh. Furthermore, the side wall of the light impurity collection chamber 6 is provided with multiple small air holes (existing technology, not shown in the figure). Further, as... Figure 1 As shown, the bottom end of the dried osmanthus flower collection bin 7 is provided with a first discharge port 16.
[0025] Furthermore, such as Figure 3 As shown, the vibrating screening assembly includes multiple support columns 10 (generally four), a spring 11 at the top of each support column 10, a screening box 12 at the top of each spring 11, a vibration motor 13 on the screening box 12 (the number of vibration motors 13 is determined according to actual conditions; this is prior art), and a first screen 14 and a second screen 15 arranged sequentially from top to bottom within the screening box 12. The aperture of the first screen 14 is larger than that of the second screen 15. Further, the first screen 14 is a 4-mesh screen; the second screen 15 is a 20-mesh screen. Further, as... Figure 3As shown, the side wall of the screening box 12 is provided with a second discharge port 18 and a third discharge port 19. The second discharge port 18 is located above the first screen 14, and the third discharge port 19 is located between the first screen 14 and the second screen 15. Furthermore, the first screen 14 and the second screen 15 are respectively inclined downward along the second discharge port 18 and the third discharge port 19.
[0026] Working principle: First, blower 5 is turned on. Then, dried osmanthus flowers containing a large number of impurities (osmanthus branches, leaves, stones, osmanthus leaf fragments, fibers, dust, etc.) are fed into air classifier 1 through feed hopper 4. Under the action of blower 5, the initially dried osmanthus flowers can be separated by air classification. Specifically, under the action of air force, most of the heavy impurities in the dried osmanthus flowers (such as osmanthus branches, leaves, stones, and other foreign objects) fall into the heavy impurity collection bin 8. The weight of the dried osmanthus flowers between heavy and light impurities falls into the dried osmanthus flower collection bin 7. The light impurities (osmanthus leaf fragments, fibers, dust, etc.) are lighter and are blown along the direction of air force to the farthest light impurity collection bin 6. In actual implementation, the best separation effect of dried osmanthus flowers can be achieved by adjusting the air force of blower 5 (this is the existing technology).
[0027] Subsequently, the material in the dried osmanthus flower collection bin 7 is taken out through the first discharge port 16 and added into the screening box 12 through the feed port located at the top of the screening box 12. Under the action of the vibrating motor 13, the screening box 12 vibrates, thereby causing the first screen 14 and the second screen 15 to vibrate and pass through the screen. After screening, large-volume impurities remain on the first screen 14 and can be removed through the second discharge port 18. The fine impurities collected below the second screen 15 are the dried osmanthus flower products, while the dried osmanthus flower products between the first screen 14 and the second screen 15 are removed through the third discharge port 19. To collect fine impurities, corresponding feeding ports can be set on the side wall or bottom wall of the screening box 12.
[0028] It is worth noting that, in actual implementation, the first discharge port 16, the second discharge port 18, the third discharge port 19, and the inlet can all be detachably equipped with a blocking plate or a piston (existing technology, not shown in the figure).
[0029] Example 2
[0030] Based on Example 1, such as Figure 4As shown, the first partition 2 is movably disposed within the air separator 1; the two opposing inner walls of the air separator 1 are provided with multiple U-shaped grooves 9 for placing the first partition 2 (in actual implementation, the first partition 2 can be freely installed in the U-shaped grooves 9 or freely removed). In this scheme, by setting multiple U-shaped grooves 9, the position of the first partition 2 within the air separator 1 can be adjusted, thereby adjusting the volume of the dried osmanthus flower collection chamber 7 and the heavy impurity collection chamber 8. Thus, based on the impurity content in the osmanthus flowers, the collection of heavy impurities and dried osmanthus flowers can be maximized. Furthermore, the bottom end of the first partition 2 is magnetically connected to the bottom wall of the air separator 1. In this scheme, the magnetic connection ensures a seamless connection between the bottom end of the first partition 2 and the bottom end of the air separator 1, preventing complete separation of the materials in the dried osmanthus flower collection chamber 7 and the heavy impurity collection chamber 8. Furthermore, the first screen 14 and the second screen 15 are respectively inclined downwards along the directions of the second discharge port 18 and the third discharge port 19 to improve the convenience of material collection.
