Description

Technical Field

[0001] This utility model relates to the field of oligosaccharide separation technology, and in particular to an oligosaccharide separation component. Background Technology

[0002] Oligosaccharide separation is a crucial step in the extraction and purification of oligosaccharides, ensuring their efficient application in functional foods, bioproducts, and many other fields. Therefore, an existing technology, a centrifugal dispersion device for isomaltooligosaccharides (publication number CN215313757U), firstly adds isomaltooligosaccharides into a first dispersion sieve cylinder through a feeding pipe. The dispersion cylinder rotates at high speed, and the centrifugal force causes the isomaltooligosaccharides inside to rotate, thus separating them according to particle size through the first and second dispersion sieve cylinders. Then, a cleaning ring rotates, allowing elastic rubber rods to continuously insert into the sieve holes of the first and second dispersion sieve cylinders. Simultaneously, the elastic rubber rods continuously tap the outer walls of the first and second dispersion sieve cylinders, generating vibration and preventing isomaltooligosaccharide particles from clogging the sieve holes.

[0003] However, in the existing technology, a large number of isomaltooligosaccharides of different sizes accumulate at the bottom of the first dispersion sieve. When particles of different sizes accumulate at the bottom of the sieve, smaller particles will fill the gaps between larger particles. This uneven filling distribution leads to an increase in particle density in local areas. The uneven size of the particles accumulated at the bottom of the sieve may lead to uneven local pressure, further aggravating the clogging problem of the sieve holes. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an oligosaccharide separation component.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an oligosaccharide separation component, comprising a mounting frame and a sieve cylinder for oligosaccharide separation, wherein an L-shaped connecting arm is fixedly installed at the top edge of the outer cylinder of the sieve cylinder, and a coaxially arranged bevel gear ring is rotatably and fixedly installed at one end of the horizontal portion of the connecting arm and the top edge of the side of the mounting frame, and a bevel gear meshing with the bevel gear ring is rotatably connected to the side of the mounting frame, and a bracket coaxially distributed with the horizontal portion of the connecting arm and sliding in the horizontal direction is inserted into the side of the mounting frame, and a rack is fixedly installed on the bracket, penetrating the mounting frame in the horizontal direction and meshing with the tooth surface of the bevel gear, and a turntable is rotatably connected to the top center of the outer cylinder of the sieve cylinder, the top edge of the turntable protruding upward and inserted with a frame inserted into the top of the outer cylinder of the sieve cylinder, a connecting strip is fixedly installed on the side of the frame, and a rotating ring rotatably connected with the bracket and coaxially arranged with the horizontal portion of the connecting arm is fixedly installed on the side of the connecting strip.

[0006] Preferably, the outer wall of the screen cylinder is inserted into the side of the mounting frame near the bottom edge, and the center of the insertion point between the side of the mounting frame and the surface of the screen cylinder is located on the central axis of the horizontal part of the connecting arm.

[0007] Preferably, a gearbox is fixedly installed at the center of the top of the inner cylinder of the screen cylinder, and the output shaft of the gearbox extends upward through the top of the screen cylinder and is fixedly connected to the center of the bottom end of the turntable.

[0008] Preferably, a dual-shaft motor located below the gearbox is fixedly installed on the inner wall of the screen cylinder. The two main shafts of the dual-shaft motor are coaxially arranged with the screen cylinder, and one of the main shafts of the dual-shaft motor is fixedly connected to the input shaft of the gearbox.

[0009] Preferably, a rotating ring for mounting the first and second dispersing screen cylinders is rotatably connected to the inner wall of the screen cylinder near the top position, and a connecting frame connected to the upper surface of the rotating ring is fixedly mounted on the other main shaft of the dual-shaft motor.

[0010] Preferably, a sealing plate is movably mounted on the surface of the connecting frame, which is inserted into the inner side of the rotating ring and used to seal the top of the first dispersing screen cylinder.

[0011] Preferably, a feed pipe is fixedly installed through the screen cylinder wall above the rotating ring.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a connecting arm is set to connect the screen cylinder and the mounting frame. The horizontal reciprocating movement of the insert frame drives the rack to move synchronously, thereby realizing the reciprocating rotation of the bevel gear in the meshing connection. Under the action of meshing connection and fixed connection, the bevel gear ring drives the connecting arm and the screen cylinder to swing back and forth. The swaying of the screen cylinder can break the tight accumulation between particles. The lateral force and vibration generated by this swaying can loosen the particles, making the distribution between particles more uniform. When the particles are evenly distributed, the possibility of the screen holes being blocked will be significantly reduced.

[0014] 2. In this utility model, the turntable can be rotated by one of the main shafts of the dual-axis motor, and the connecting frame can be rotated by the other main shaft of the dual-axis motor, thereby realizing that the rotating ring drives the first and second dispersing sieve cylinders to rotate at high speed, so that isomalt oligosaccharides are screened and separated under the action of centrifugal force. Thus, one power can realize the operation of two mechanisms. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, an oligosaccharide separation component includes a mounting frame 1 and a sieve cylinder 2 for oligosaccharide separation. Isomaltooligosaccharides are poured into the sieve cylinder 2, and the isomaltooligosaccharides are separated by the centrifugal force generated by the rotation of the first and second dispersion sieve cylinders set inside the sieve cylinder 2. The principle of isomaltooligosaccharide separation by the sieve cylinder 2 has been disclosed in the prior art.

[0023] An L-shaped connecting arm 5 is fixedly installed at the top edge of the outer cylinder of the sieve cylinder 2. One end of the horizontal part of the connecting arm 5 is rotatably and fixedly installed with a coaxially arranged bevel gear ring 11 at the top edge of the side of the mounting frame 1. By driving the bevel gear ring 11 to rotate, the connecting arm 5 can be rotated, thereby causing the sieve cylinder 2 connected to the connecting arm 5 to swing, thus shaking and dispersing the isomaltooligosaccharides accumulated in the sieve cylinder 2. A bevel gear 12 that meshes with the bevel gear ring 11 is rotatably connected to the side of the mounting frame 1. A bracket 3 that is coaxially distributed with the horizontal part of the connecting arm 5 and slides horizontally is inserted into the side of the mounting frame 1. A rack 4 that passes through the mounting frame 1 horizontally and meshes with the tooth surface of the bevel gear 12 is fixedly installed on the bracket 3. By using the horizontal reciprocating movement of the bracket 3 to drive the horizontal reciprocating movement of the rack 4, the bevel gear 12 that meshes with the rack 4 can drive the bevel gear ring 11 that meshes with it to rotate. In addition, the bevel gear 12 in this solution has two tooth surfaces, one of which is a helical tooth surface for meshing with the bevel gear ring 11. Ring 11 engages with the other tooth surface, which is a straight tooth surface used for engagement with rack 4. A turntable 7 is rotatably connected to the center of the top of the outer cylinder of screen cylinder 2. The top edge of the turntable 7 protrudes upward and is inserted into a frame 8 that is inserted into the top of the outer cylinder of screen cylinder 2. By driving the turntable 7 to rotate, the frame 8 can reciprocate relative to the side of the mounting frame 1 under the constraint of being inserted into the top of screen cylinder 2. A connecting strip 9 is fixedly installed on the side of the frame 8. A rotating ring 6 is fixedly installed on the side of the connecting strip 9, which is rotatably connected to the mounting frame 3 and coaxial with the horizontal part of the connecting arm 5. When the frame 8 reciprocates, it drives the connecting strip 9 to reciprocate, which in turn drives the mounting frame 3 to reciprocate under the connection of the rotating ring 6. In addition, by utilizing the rotational connection between the rotating ring 6 and the mounting frame 3, when the screen cylinder 2 revolves around the central axis of the horizontal part of the connecting arm 5, the corresponding frame 8 will also drive the connecting strip 9 to revolve around the central axis of the horizontal part of the connecting arm 5. When the connecting strip 9 revolves, it will drive the rotating ring 6 to rotate on the surface of the mounting frame 3 around the central axis of the horizontal part of the connecting arm 5.

[0024] The outer wall of the screen cylinder 2 is inserted into the side of the mounting frame 1 near the bottom edge. The center of the insertion point between the side of the mounting frame 1 and the surface of the screen cylinder 2 is located on the central axis of the horizontal part of the connecting arm 5, which can ensure that the screen cylinder 2 swings smoothly and stably.

[0025] A gearbox 17 is fixedly installed at the center of the top of the inner cylinder of the screen cylinder 2. The output shaft of the gearbox 17 extends upward through the top of the screen cylinder 2 and is fixedly connected to the center of the bottom of the turntable 7. A dual-shaft motor 15 is fixedly installed on the inner wall of the screen cylinder 2 below the gearbox 17. The two main shafts of the dual-shaft motor 15 are coaxial with the screen cylinder 2, and one of the main shafts of the dual-shaft motor 15 is fixedly connected to the input shaft of the gearbox 17. When the dual-shaft motor 15 starts, it drives the turntable 7 to rotate at different speeds after being reduced in speed by the gearbox 17. A rotating ring 14 for installing the first and second dispersion screen cylinders is rotatably connected to the inner wall of the screen cylinder 2 near the top. Figure 3As shown, a first and second dispersing screen cylinders are installed from the inside to the outside at the bottom of the rotating ring 14, and the rotating ring 14 is connected to the first dispersing screen cylinder through the middle. The working principle and operation mode of the first and second dispersing screen cylinders refer to the prior art in the background. The other main shaft of the dual-shaft motor 15 is fixedly mounted with a connecting frame 16 connected to the upper surface of the rotating ring 14. A sealing plate 10 is movably mounted on the surface of the connecting frame 16, which is inserted into the inner side of the rotating ring 14 and used to seal the top of the first dispersing screen cylinder. In this solution, the sealing plate 10 is driven to move up and down in and out of the rotating ring 14 by installing an electric push rod on the connecting frame 16. A feed pipe 13 is fixedly installed through the wall above the rotating ring 14. By rising and separating from the rotating ring 14 through the sealing plate 10, isomaltose oligosaccharides can be poured into the sieve cylinder 2 through the feed pipe 13 and accumulate above the rotating ring 14. The isomaltose oligosaccharides enter the first dispersion sieve cylinder through the open inner wall of the rotating ring 14. Then, the sealing plate 10 descends and reseals the inner side of the rotating ring 14, that is, the upper opening of the first dispersion sieve cylinder. The connecting frame 16 is rotated by the other main shaft of the dual-shaft motor 15, thereby realizing that the rotating ring 14 drives the first and second dispersion sieve cylinders to rotate at high speed, so that the isomaltose oligosaccharides are screened and separated under the action of centrifugal force.

[0026] In operation, when separating and screening isomaltooligosaccharides, the sieve cylinder 2 is driven by the deceleration effect of the gearbox 17 to rotate the turntable 7 at different speeds. By driving the turntable 7 to rotate, the insert frame 8 moves back and forth relative to the side of the mounting frame 1 under the constraint of being inserted into the top of the sieve cylinder 2. When the insert frame 8 moves back and forth, it drives the connecting strip 9 to move back and forth. Under the connection of the rotating ring 6, it drives the insert frame 3 to move back and forth. The horizontal reciprocating movement of the insert frame 3 drives the horizontal reciprocating movement of the rack 4. This enables the bevel gear 12, which is meshed with the rack 4, to drive the meshed bevel gear ring 11 to rotate back and forth. By driving the bevel gear ring 11 to rotate, it drives the connecting arm 5 to rotate. This enables the sieve cylinder 2 connected to the connecting arm 5 to swing, thereby shaking and dispersing the isomaltooligosaccharides accumulated in the sieve cylinder 2.

Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the electric linear actuator, dual-axis motor 15, and gearbox 17 will not be explained in detail.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
