Description

Technical Field

[0001] The invention relates to the technical field of plant extraction, in particular to a device for centrifugally extracting supernatant from palm rattan buds. Background Art

[0002] Palm vines are perennial climbing plants of the genus Ulmus, belonging to the family Arecaceae. The buds of the palm vine, a key structure in its growth, not only protect the development of flowers and fruits but also contain a rich chemical composition. Research has shown that the buds may contain a variety of active substances, including polysaccharides, flavonoids, and alkaloids. These ingredients have potential value in antioxidant and immunomodulatory activities, and show broad application prospects in food additives, functional foods, and natural medicines. The supernatant of the palm vine buds can usually be extracted through methods such as centrifugation and filtration.

[0003] Patent No. CN221807772U discloses a device for extracting supernatant from palm vine buds by centrifugal filtration to solve the problem of debris adhering to the inner wall of the crushing drum, making it difficult to clean the residue. However, the above patent has the following drawbacks:

[0004] First, during the crushing process, some of the vine cells will adhere to the stirring rod, while some will be thrown onto the inner wall of the crushing drum due to the centrifugal force of the rotating stirring roller. Although the lifting screen of the above-mentioned patent can scrape off the particles adhering to the inner wall of the crushing drum, it cannot remove the particles adhering to the stirring rod. Moreover, the scraped particles will still fall onto the lifting screen and will not pass through the lifting screen and fall into the centrifugal device in time. As time goes by, the particles that do not fall into the centrifugal device will gradually lose water, ultimately resulting in a decrease in the amount of extract during centrifugal extraction.

[0005] Secondly, during the crushing process of the rattan bag, the cells inside the rattan bag will be broken by external force, causing the cell fluid to flow out. The outflowing cell fluid will adhere to the stirring rod and the inner wall of the crushing cylinder. The above patent cannot remove the cell fluid adhered to the stirring rod and the inner wall of the crushing cylinder, so that the rattan bag will have the problem of cell fluid loss during the crushing stage, which will lead to a decrease in the amount of subsequent extract. Summary of the Invention

[0009] Furthermore, a receiving frame is fixed on both sides of the crushing box, and two groups of symmetrical strip grooves are opened on the side walls corresponding to the crushing box and the receiving frame. Each group of strip grooves is vertical, and the upper end of each group of strip grooves passes through the top of the corresponding side plate of the crushing box. Two shaft seats are fixed in each receiving frame, and the two end tubes in each group of hollow rollers pass through the two strip grooves respectively and are connected to the corresponding two shaft seats. An end ring is coaxially formed on the end of each end tube facing the crushing box, and the outer diameter of the end ring is smaller than the outer diameter of the end tube. Each semicircular ring distributed at the head and tail is coaxially formed with a semicircular mounting ring facing the corresponding end tube, and each mounting ring is fixedly mounted on the corresponding end ring.

[0010] Furthermore, each semicircular ring is coaxially formed with a semicircular connecting ring on one side facing the adjacent semicircular ring, each group of connecting parts is arranged between two adjacent connecting rings, and each group of connecting parts includes pins and hole sleeves. The number of pins and hole sleeves is the same, both being several. The pins and hole sleeves are evenly divided into two groups and are respectively formed on the inner walls of two adjacent connecting rings, and each pin can be inserted into the corresponding hole sleeve.

[0011] Furthermore, each curved air shield includes two curved plates and two end blocks. The two curved plates are symmetrically arranged on both sides of the corresponding ventilation groove.

[0017] Firstly, the device uses two sets of counter-rotating serrated blades to crush the rattan bags before centrifugal extraction. During the rotation of the serrated blades, each air jet ring can generate gas flowing toward the side walls of the serrated blades. This gas flushing method causes the crushed materials and cell fluid attached to the side walls of the serrated blades to fall downward toward the discharge port, thereby increasing the amount of raw materials of crushed materials and cell fluid entering the centrifugal device, and thus relatively increasing the final amount of extract;

[0018] Secondly, after the jet ring of the device rotates, the position of the curved air shield will not change because the curved air shield is connected to the air supply pipe, and the air supply pipe is fixedly connected to the crushing box. Therefore, the gas flowing along the curved air shield can only be ejected from the air holes that rotate downward, thereby ensuring that the jet ring will always generate gas that is sprayed downward and toward the serrated blade during the rotation of the serrated blade;

[0019] Third, two sets of strip jet chambers are provided in the top frame of the device, which are used to spray the corresponding inner walls of the crushing box, thereby promoting the crushed materials and cell fluid attached to the inner wall of the crushing box to fall downward to the discharge port through the flushing of gas.

DETAILED DESCRIPTION

[0040] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] refer to Figures 1 to 19 The device shown is a centrifugal extraction device for supernatant of palm rattan buds, comprising a crushing box 1, with a feed port 2 and a discharge port 3 provided at the top and bottom of the crushing box 1, respectively. Two sets of self-cleaning crushing mechanisms 4 are provided in the crushing box 1, each set of self-cleaning crushing mechanisms 4 comprises a hollow roller 5, an air supply pipe 6 and a plurality of circular serrated blades 7, the two sets of hollow rollers 5 are horizontal and parallel to each other, and each set of hollow rollers 5 comprises an air jet pipe 8 and two end pipes 9 respectively coaxially connected to the ends of the air jet pipe 8 (such as Figure 13As shown), the two end pipes 9 are rotatably connected to the crushing box 1, the air injection pipe 8 includes a plurality of air injection rings 10 connected end to end, and a connecting piece is provided between adjacent air injection rings 10. The first and last air injection rings 10 are respectively connected to the two end pipes 9. Each air injection ring 10 is a hollow structure, and the inner ring of each air injection ring 10 is an open structure, and each air injection ring 10 is provided with a plurality of air holes 11. The air supply pipe 6 is coaxially arranged in the hollow roller 5, and the air supply pipe 6 is fixedly connected to the crushing box 1. One end of the air supply pipe 6 is provided with an air inlet 12 (as shown). Figure 3 As shown in the figure, the other end of the air supply pipe 6 is a closed structure. A plurality of downward ventilation grooves 13 corresponding to the jet rings 10 are provided on the outer wall of the air supply pipe 6. An arc-shaped air shield 14 fixedly connected to the air supply pipe 6 is provided between each ventilation groove 13 and the corresponding jet ring 10. A plurality of serrated blades 7 are equidistantly distributed along the axial direction of the hollow roller 5, and each serrated blade 7 is coaxially fixed between two adjacent jet rings 10.

[0042] In actual use, the crushing box 1 is provided with a driving member (not shown in the figure) for driving the two sets of hollow rollers 5 to rotate in opposite directions. A centrifugal device (not shown in the figure) connected to the discharge port 3 is provided below the crushing box 1. An air source (not shown in the figure) connected to the air inlet 12 is provided next to each air supply pipe 6.

[0043] The specific crushing process is as follows: first, the two sets of hollow rollers 5 are driven by the driving member to rotate in opposite directions, and then the rattan bag is poured into the crushing box 1 from the feed port 2. When the hollow rollers 5 rotate, each set of hollow rollers 5 will drive the several serrated blades 7 thereon to rotate synchronously, so that the rattan bag will be chopped by the several serrated blades 7 on the two sets of hollow rollers 5. The chopped fragments will fall to the discharge port 3 and finally be discharged to the centrifugal device through the discharge port 3. In the process of the serrated blades 7 chopping the rattan bag, some of the fragments and cell fluid will adhere to the serrated blades 7. At this time, the air source will pass through the air inlet 12 to the corresponding air supply pipe 6. Gas is injected into the air supply pipe 6. When the gas enters the air supply pipe 6, since one end of the air supply pipe 6 is a closed structure, the gas will only flow into the corresponding jet ring 10 through several ventilation grooves 13. When the gas flows into the jet ring 10, it will be restricted by the corresponding arc-shaped air shield 14. Therefore, the gas in the jet ring 10 will only be discharged by rotating to the air holes 11 corresponding to the ventilation grooves 13. Then, when the jet ring 10 rotates, the gas in the jet ring 10 will only be ejected from the lower half of the jet ring 10, and finally the debris and cell fluid adhering to the serrated blade 7 will be flushed to the discharge port 3 through the downwardly ejected gas.

[0044] In order to show the specific structure of each jet ring 10, the following features are set:

[0045] Each jet ring 10 includes two semicircular rings 15 distributed vertically. The outer ring of each semicircular ring 15 bulges outward to form a convex ring 16. The cross-section of the convex ring 16 is triangular, and the convex ring 16 has two symmetrical semicircular inclined surfaces 17. The multiple air holes 11 on each jet ring 10 are all opened on the corresponding semicircular inclined surfaces 17.

[0046] The two semicircular rings 15 merge toward each other to form the jet ring 10. In this way, it is convenient to embed the arc-shaped air shield 14 fixedly connected to the air supply pipe 6 into the jet ring 10. When gas is injected into the air supply pipe 6, the gas will flow into the corresponding jet ring 10 through several ventilation grooves 13. Finally, the gas entering the jet ring 10 will be discharged from the air hole 11 corresponding to the ventilation groove 13 through the rotation. Since the air hole 11 is provided on the semicircular inclined surface 17, the gas discharged from the air hole 11 will flow accurately to the side wall of the adjacent serrated blade 7, and finally the debris and cell fluid attached to the serrated blade 7 will be flushed to the blanking port by gas flushing.

[0047] In order to show how the end pipe 9 is rotatably connected to the crushing box 1 and how the first and last air-jet rings 10 are fixedly connected to the end pipe 9, the following features are provided:

[0048] Both sides of the crushing box 1 are fixed with a receiving frame 18 (such as Figure 7 As shown), two groups of symmetrical strip through grooves 19 are provided on the side walls corresponding to the crushing box 1 and the accommodating frame 18, each group of strip through grooves 19 is vertical, and the upper end of each group of strip through grooves 19 passes through the top of the corresponding side plate of the crushing box 1, and two shaft seats 20 are fixed in each accommodating frame 18. The two end tubes 9 in each group of hollow rollers 5 pass through the two strip through grooves 19 and are connected to the corresponding two shaft seats 20, and each end tube 9 facing the crushing box 1 is coaxially formed with an end ring 21, the outer diameter of the end ring 21 is smaller than the outer diameter of the end tube 9, and each semicircular ring 15 distributed at the head and tail is coaxially formed with a semicircular mounting ring 22 facing the corresponding end tube 9, and each mounting ring 22 is fixedly sleeved on the corresponding end ring 21.

[0049] Before installing the end tubes 9, several jet rings 10 are first installed between the two end tubes 9. The specific process is as follows: first, the head and tail jet rings 10 are fixedly connected to the two end tubes 9. During this process, the semicircular rings 15 distributed at the head and tail are fixed to the end tubes 9 through the corresponding mounting rings 22. When the semicircular rings 15 distributed at the head and tail are fixed to the end tubes 9, the upper and lower semicircular rings 15 are merged to form the corresponding jet ring 10. At this time, the head and tail jet rings 10 are fixed. Thereafter, the remaining jet rings 10 are connected to each other and fixedly connected to the head and tail jet rings 10 through connecting parts. Finally, several jet rings 10 will form a jet pipe 8, and the jet pipe 8 will form a hollow roller 5 with the two end tubes 9. When the hollow roller 5 is assembled, the hollow roller 5 is placed downward into the crushing box 1. During this process, each end tube 9 will pass downward into the strip through groove 19, and finally the end tube 9 will be connected to the corresponding shaft seat 20.

[0050] In order to show the specific structure of the connector, the following features are set:

[0051] Each semicircular ring 15 is coaxially formed with a semicircular connecting ring 23 (such as Figure 18 As shown in the figure, each group of connecting parts is arranged between two adjacent connecting rings 23, and each group of connecting parts includes a pin 24 and a hole sleeve 25. The number of the pins 24 and the hole sleeve 25 is the same, and the pins 24 and the hole sleeve 25 are evenly divided into two groups and are respectively formed on the inner walls of the two adjacent connecting rings 23, and each pin 24 can be inserted into the corresponding hole sleeve 25.

[0052] The specific process of assembling the hollow roller 5 is as follows: first, the two semicircular rings 15 at the head and tail are combined up and down and fixed on the corresponding end tube 9, and then the remaining pairs of semicircular rings 15 are combined and pushed one by one onto the two semicircular rings 15 at the head and which have formed the jet ring 10. In this process, the pin 24 on each semicircular ring 15 will be inserted into the hole sleeve 25 on the next semicircular ring 15, so as to realize the head and tail connection of several jet rings 10 by plugging, and then the positions are fixed. The hole sleeve 25 on the tail semicircular ring 15 is sleeved into the pin 24 on the front semicircular ring 15, and finally the assembly of the hollow roller 5 is realized. In order to prevent the plug-in connection between the pin 24 and the hole sleeve 25 from being loose, the pin 24 is tapered as a whole when processing the pin 24, that is, the closer the pin 24 is to the hole sleeve 25 along its axial direction, the smaller its diameter is, and the minimum diameter of the pin 24 is not greater than the inner diameter of the hole sleeve 25, so that when plugging in, the plug-in connection between the pin 24 and the hole sleeve 25 can be prevented from being loose through interference fit.

[0053] In order to show the specific structure of the arc-shaped air shield 14, the following features are set:

[0054] Each arc-shaped air shield 14 includes two arc-shaped plates 26 and two end blocks 27. The two arc-shaped plates 26 are symmetrically arranged on both sides of the corresponding ventilation groove 13. The two end blocks 27 connect the two ends of the two arc-shaped plates 26 respectively. The inner circle of each arc-shaped plate 26 is fitted with the outer wall of the air supply pipe 6, and the outer circle of each arc-shaped plate 26 extends into the inner cavity of the corresponding jet ring 10. The shape of each end block 27 is consistent with the cross-sectional shape of the corresponding semicircular ring 15. A No. 1 rubber strip 28 is fitted on the peripheral wall of each end block 27, and a No. 2 rubber strip 29 is fitted on one side of each arc-shaped plate 26.

[0055] Since each arc-shaped air shield 14 is connected to the air supply pipe 6, when the hollow roller 5 rotates, the arc-shaped air shield 14 will not rotate, thereby ensuring that the gas discharged from the ventilation groove 13 can only be discharged along the arc-shaped air shield 14 through the obstruction of the two arc-shaped plates 26 and the two end blocks 27 in the arc-shaped air shield 14. Then, when the hollow roller 5 rotates, the gas discharged from the arc-shaped air shield 14 can only flow out by rotating to the air hole 11 below, ultimately ensuring that the jet direction of the jet ring 10 is always downward, wherein the No. 1 rubber strip 28 on the end block 27 and the No. 2 rubber strip 29 on the arc plate 26 are used to prevent the end block 27 and the arc plate 26 from hard friction with the inner cavity of the jet ring 10.

[0056] In order to show how the curved air shield 14 is installed, the following features are set:

[0057] The two ends of each air supply pipe 6 pass through the corresponding two end pipes 9, and the two ends of each air supply pipe 6 are fixedly connected to the two receiving frames 18. Two symmetrical limiting strips 30 (such as Figure 19 As shown), the length direction of each limiting strip 30 is parallel to the axial direction of the air supply pipe 6, and each end block 27 is formed with an insert block 31 that is plugged into and fits with the limiting strip 30.

[0058] When installing the curved air shield 14, the curved air shield 14 and the jet ring 10 are installed synchronously. First, the air supply pipe 6 is passed through the two end pipes 9, and then the corresponding semicircular ring 15 is put on the outside of the curved air shield 14. Finally, several jet rings 10 are connected end to end. Then, in the process of connecting several jet rings 10 end to end, the curved air shield 14 will be connected to the air supply pipe 6 through the plug-in cooperation of the plug block 31 and the limit strip 30 thereon, and when several jet rings 10 are combined end to end into the jet pipe 8, each curved air shield 14 will correspond to the ventilation groove 13.

[0059] In order to prevent the chopped rattan bag debris and cell fluid from falling into the air-jet ring 10 from the air holes 11 rotating upward, the following features are provided:

[0060] A semicircular baffle ring 32 is provided above each arc-shaped air baffle 14, and connecting rods 33 are formed at both ends of the baffle ring 32. Each connecting rod 33 is fixedly connected to the corresponding plug block 31, and a No. 3 rubber strip 34 is fitted on the outer wall of each baffle ring 32.

[0061] When installing the arc-shaped air baffle 14, the upper and lower semicircular rings 15 will be respectively mounted on the outside of the baffle ring 32 and the arc-shaped air baffle 14 in the process of merging toward each other to form the jet ring 10. Thereafter, when the arc-shaped air baffle 14 is connected to the air supply pipe 6 by plugging and matching the plug block 31 and the limit strip 30, the baffle ring 32 connected to the arc-shaped air baffle 14 through the connecting rod 33 will be installed on the air supply pipe 6 together. Thereafter, when the hollow roller 5 rotates, the baffle ring 32 will block the air hole 11 rotated to the top, so as to prevent the chopped debris and cell fluid from falling into the jet ring 10 from the air hole 11 rotated to the top. The No. 3 rubber strip 34 is used to prevent the baffle ring 32 from having hard friction with the inner cavity of the jet ring 10.

[0062] In order to show how the serrated blade 7 is installed, the following features are provided:

[0063] A plurality of limit blocks 35 are formed on the outer wall of each connecting ring 23, and a circular groove 36 is provided at the center of each serrated blade 7 and is sleeved on the connecting ring 23. A plurality of slots 37 are provided in each circular groove 36, and the number of limit blocks 35 on the upper and lower connecting rings 23 is consistent with the number of slots 37 in each circular groove 36.

[0064] The installation of the serrated blade 7 is carried out together with the end-to-end connection of the jet ring 10. After the upper and lower semicircular rings 15 are merged to form the jet ring 10, the serrated blade 7 is sleeved on the connecting ring 23 after the upper and lower semicircular rings 15 are merged into a circle through the circular groove 36. At this time, the limit block 35 will be inserted into the corresponding slot 37. Thereafter, the next jet ring 10 is pushed to the front jet ring 10. In this process, the two adjacent jet rings 10 are adjacent to each other through the cooperation of the latch 24 and the hole sleeve 25. The serrated blade 7 will be clamped between the two adjacent jet rings 10, and the serrated blade 7 will be connected to the jet ring 10 through the plug-in cooperation of the limit block 35 and the slot 37. Finally, when several jet rings 10 rotate synchronously, the serrated blade 7 will rotate with the jet ring 10. Among them, after the serrated blade 7 on each group of hollow rollers 5 is installed, the serrated blades 7 on the two groups of hollow rollers 5 are staggered (such as Figure 6 shown).

[0065] In order to facilitate the falling of the debris and cell fluid adhering to the inner wall of the crushing box 1, the following features are provided:

[0066] A top frame 38 is fixed on the top of the crushing box 1, and the feed port 2 is arranged on the top frame 38. Two sets of symmetrical strip-shaped jet chambers 39 (such as Figure 6 As shown in the figure, each set of strip jet chambers 39 is tilted toward the corresponding inner wall of the crushing box 1, and two vertically downward strip baffles 40 are formed on the side walls on both sides of the top frame 38, and each strip baffle 40 is inserted downward into the corresponding strip through groove 19.

[0067] During the crushing process of the rattan bag, the rotating sawtooth blade 7 will throw the crushed materials and cell fluid to the inner walls of both sides of the crushing box 1 due to centrifugal force. At this time, each strip-shaped jet chamber 39 will spray toward the corresponding inner wall of the crushing box 1, thereby promoting the crushed materials and cell fluid attached to the inner wall of the crushing box 1 to fall toward the discharge port 3 through the impact of the gas. Among them, when processing the strip-shaped jet chamber 39, one end of the strip-shaped jet chamber 39 is a closed structure, and the other end is provided with a gas injection port 41 (such as Figure 9 As shown), a plurality of air jet ports 42 are provided on the strip-shaped air jet chamber 39. During actual use, the gas source supplying the air to the air delivery pipe 6 will inject a portion of the gas into the strip-shaped air jet chamber 39 through the gas injection port 41. Finally, the gas entering the strip-shaped air jet chamber 39 will be sprayed onto the corresponding inner wall of the crushing box 1 through the plurality of air jet ports 42.

[0068] Working principle:

[0069] In actual use, the crushing box 1 is provided with a driving member (not shown in the figure) for driving the two sets of hollow rollers 5 to rotate in opposite directions. A centrifugal device (not shown in the figure) connected to the discharge port 3 is provided below the crushing box 1. An air source (not shown in the figure) connected to the air inlet 12 is provided next to each air supply pipe 6.

[0070] The specific crushing process is as follows: first, the two sets of hollow rollers 5 are driven by the driving member to rotate in opposite directions, and then the rattan bag is poured into the crushing box 1 from the feed port 2. When the hollow rollers 5 rotate, each set of hollow rollers 5 will drive the several serrated blades 7 thereon to rotate synchronously, so that the rattan bag will be chopped by the several serrated blades 7 on the two sets of hollow rollers 5. The chopped fragments will fall to the discharge port 3 and finally be discharged to the centrifugal device through the discharge port 3. In the process of the serrated blades 7 chopping the rattan bag, some of the fragments and cell fluid will adhere to the serrated blades 7. At this time, the air source will pass through the air inlet 12 to the corresponding air supply pipe 6. Gas is injected into the air supply pipe 6. When the gas enters the air supply pipe 6, since one end of the air supply pipe 6 is a closed structure, the gas will only flow into the corresponding jet ring 10 through several ventilation grooves 13. When the gas flows into the jet ring 10, it will be restricted by the corresponding arc-shaped air shield 14. Therefore, the gas in the jet ring 10 will only be discharged by rotating to the air holes 11 corresponding to the ventilation grooves 13. Then, when the jet ring 10 rotates, the gas in the jet ring 10 will only be ejected from the lower half of the jet ring 10, and finally the debris and cell fluid adhering to the serrated blade 7 will be flushed to the discharge port 3 through the downwardly ejected gas.

[0071] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
