Description

Technical Field

[0001] This invention relates to the field of extraction and separation equipment, specifically to a high-wet gradient extraction and separation equipment for high-protein starch. Background Technology

[0002] In the starch processing industry, especially in the high-wet extraction of high-protein starch, the efficient separation of starch from components such as protein is a key step in improving product quality and production efficiency. Traditional centrifugal separation equipment mostly adopts a disc structure, that is, a disc with multiple sets of circular holes, into which a carrier tube loaded with material is inserted, and centrifugal force is generated by the overall rotation of the disc to achieve separation.

[0003] However, these traditional devices have obvious limitations: on the one hand, when the disc rotates as a whole, the rotation center of all the carrier tubes depends on the central axis of the disc, making it difficult to ensure that each carrier tube rotates around its own axial center point. This can easily affect the separation effect due to uneven distribution of centrifugal force, resulting in incomplete separation of starch and protein and reduced product purity. On the other hand, the motion of traditional devices is relatively simple, usually only able to achieve rotational centrifugation in one direction. It cannot combine multi-angle and multi-dimensional motion modes such as oscillation and lateral movement, making it difficult to adapt to the separation requirements of starch materials under different gradients in high-wet extraction, resulting in low separation efficiency.

[0004] Furthermore, traditional equipment has shortcomings in its method of fixing the carrier tube, often employing simple plug-in or snap-fit ​​structures. During high-speed rotation or complex movements, the carrier tube is prone to loosening or shaking, which not only affects separation stability but may also lead to material leakage, posing safety hazards. At the same time, the ease of operation and observation of the equipment needs improvement. Some equipment requires opening the cover to observe the internal separation process; frequent opening and closing not only affects work efficiency but may also disrupt the internal working environment of the equipment.

[0005] Therefore, in order to solve the problems of poor centrifugation effect, single motion mode, unstable fixation and inconvenient observation of traditional centrifugal separation equipment in high-wet high-protein starch extraction, the development of a separation equipment with multi-angle centrifugation, multi-dimensional motion, stable fixation and convenient observation functions has become a practical need in the industry. To this end, we have proposed a high-wet high-protein starch gradient extraction and separation equipment. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a high-wet high-protein starch gradient extraction and separation equipment, which solves the aforementioned problems.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a high-wet high-protein starch gradient extraction and separation equipment, comprising a shell, a cover plate hinged to the opening of the shell, a rectangular opening provided on the cover plate, a transparent glass disposed inside the rectangular opening, a swingable concave support plate disposed inside the shell, two movable blocks capable of mirror-moving laterally disposed on the concave support plate, and four sets of independently rotatable clamping heads disposed on the movable blocks, the clamping heads being used to fix the support test tubes.

[0008] Preferably, a rotating shaft is fixedly installed on both sides of the concave bearing plate, and a motor is fixedly installed on one side of the housing. The output shaft of the motor extends through the housing and into the housing, and the output shaft of the motor is connected to the output shaft on one side.

[0009] Preferably, the concave support plate is provided with a rack structure, and two moving blocks are connected to the rack structure. The rack structure is used to drive the two moving blocks to move laterally in a mirror manner.

[0010] Preferably, the rack structure includes a motor structure, slide bars, and teeth. The concave bearing plate has a groove on its bearing surface. Two slide bars are respectively arranged on both sides inside the groove. Multiple sets of teeth are installed at equal intervals on the side wall of the two slide bars that are close to each other. The motor structure meshes with the teeth. An mounting plate is fixedly installed on the top of the two slide bars that are opposite to each other. The moving block is fixedly connected to the mounting plate.

[0011] Preferably, an inner wall groove is formed on the inner wall of the groove, and a side protrusion is integrally formed on the slide bar corresponding to the position of the inner wall groove, and the side protrusion is slidably engaged with the inner wall groove.

[0012] Preferably, the motor structure includes a second motor and a second gear. A motor mounting base is fixedly installed at the bottom of the concave support plate. The second motor is fixedly installed on the inner side of the motor mounting base. The output shaft of the second motor extends into the interior of the groove. A second gear is fixedly installed on the output shaft of the second motor, and the second gear meshes with a tooth.

[0013] Preferably, the clamping head includes a support tube and a fixing structure. The fixing structure is disposed on the support tube, the support tube is rotatably disposed on the moving block, and one end of the support tube extends to the inside of the moving block.

[0014] Preferably, the bearing tube extends into the inner end of the moving block and is equidistantly installed with multiple sets of teeth II. A motor III is fixedly installed on the bottom inner wall of the moving block, and a gear I is fixedly installed on the output shaft of the motor III. The gear I meshes with the teeth II.

[0015] Preferably, the inner wall of the circular hole on the movable block for inserting the bearing tube is provided with an annular internal groove, and the bearing tube is integrally formed with an annular protrusion at the position corresponding to the annular internal groove, and the annular protrusion is rotatably engaged with the annular internal groove.

[0016] Preferably, the fixing structure includes multiple sets of rubber strips and a threaded ring threadedly installed on the top of the bearing tube. Multiple sets of strip-shaped openings are equally spaced on the bearing tube. Rubber strips are fixedly installed inside the strip-shaped openings. The upper and lower ends of the rubber strips are fixedly installed on the upper and lower inner walls of the strip-shaped openings. The rubber strips are rectangular on both sides inside and outside the bearing tube. An inclined notch is opened on the lower inner wall of the threaded ring.

[0017] Compared with the prior art, the present invention provides a high-wet high-protein starch gradient extraction and separation equipment, which has the following beneficial effects: Improved centrifugal separation effect: Each clamping head can rotate independently, and the rotation center is based on the axial center point of the carrying tube, which can ensure uniform distribution of centrifugal force, making the separation of starch and protein and other components more thorough, effectively improving product purity, and solving the problem of poor centrifugation effect caused by the uniform rotation center of traditional disc centrifuge equipment.

[0018] Achieving multi-dimensional motion separation: The equipment combines the swinging of the concave support plate, the mirrored lateral movement of two moving blocks, and the independent rotation of the clamping head to form a multi-angle, multi-dimensional composite motion mode. This diverse motion pattern can adapt to the separation requirements of starch materials under different gradients in high-wet extraction, significantly improving separation efficiency.

[0019] Enhanced stability of the carrier tube: The clamping head's fixing structure uses the rotation of the threaded ring and the inclined notch to compress the rubber strip, causing the rubber strip to deform inward and tightly adhere to the carrier tube, thus achieving a stable fixation. Even during high-speed rotation or complex movements, the carrier tube is not prone to loosening or shaking, reducing the risk of material leakage and ensuring the stability and safety of the separation process.

[0020] Easy to observe the operation process: The transparent glass design on the cover allows operators to observe the separation process inside the equipment in real time without opening the cover. This not only makes it easy to keep track of the work progress, but also avoids the interference of frequent opening and closing of the cover on the internal working environment of the equipment, thus improving the convenience of operation.

[0021] The structural design is reasonable and stable: the connection and cooperation of each component are precise. For example, the slide bar is slidably engaged with the groove on the inner wall of the groove through the side protrusion, and the bearing tube is rotated and engaged with the inner groove of the moving block through the annular protrusion. This ensures the stability and smoothness of the equipment during operation and extends the service life of the equipment. Attached Figure Description

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

[0025] Please see Figure 1-9A high-wet high-protein starch gradient extraction and separation equipment includes a shell 1, with a cover plate 2 hinged to the opening of the shell 1. The cover plate 2 has a rectangular opening, and the interior of the rectangular opening is filled with transparent glass. Inside the shell 1 is a swingable concave support plate 3. The concave support plate 3 has two moving blocks 5 that can move laterally in a mirror image. The moving blocks 5 have four sets of independently rotating clamping heads 6. The clamping heads 6 are used to fix the support test tube, which is used to load starch material. When separation is required, the material is injected into the support test tube, and then it is installed on the clamping heads 6. Then, the concave support plate 3 swings while the two moving blocks 5 move laterally in a mirror image. Then the clamping heads 6 rotate to achieve multi-angle centrifugation and separation.

[0026] Furthermore, rotating shafts are fixedly installed on both sides of the concave bearing plate 3, and motor 4 is fixedly installed on one side of the outer casing 1. The output shaft of motor 4 extends through the outer casing 1 into the inner part of the outer casing 1. The output shaft of motor 4 is connected to the output shaft on one side. When the cover plate 2 needs to swing, the output shaft of motor 4 reciprocates and rotates, thereby driving the concave bearing plate 3 to swing.

[0027] Furthermore, a rack structure is provided on the concave support plate 3, and two moving blocks 5 are connected to the rack structure. The rack structure is used to drive the two moving blocks 5 to move laterally in a mirror manner.

[0028] Furthermore, the rack and pinion structure includes a motor structure, slide bars 11, and teeth 13. A groove 9 is provided on the bearing surface of the concave bearing plate 3. Two slide bars 11 are respectively arranged on both sides inside the groove 9, and multiple sets of teeth 13 are equidistantly installed on the side wall of the two slide bars 11 that are close to each other. The motor structure meshes with the teeth 13. A mounting plate 14 is fixedly installed on the top of the two slide bars 11 that are opposite to each other. The moving block 5 is fixedly connected to the mounting plate 14. The motor structure drives the two slide bars 11 to move laterally in the groove 9, which in turn drives the mounting plate 14 to move laterally, and then drives the moving block 5 to move.

[0029] Furthermore, an inner wall groove 10 is provided on the inner wall of the groove 9, and a side protrusion 12 is integrally formed on the slide bar 11 corresponding to the position of the inner wall groove 10. The side protrusion 12 is slidably engaged with the inner wall groove 10.

[0030] Furthermore, the motor structure includes a second motor 8 and a second gear 25. A motor mounting base 7 is fixedly installed on the bottom of the concave support plate 3. A second motor 8 is fixedly installed on the inner side of the motor mounting base 7. The output shaft of the second motor 8 extends into the interior of the groove 9. A second gear 25 is fixedly installed on the output shaft of the second motor 8. The second gear 25 meshes with the first tooth 13. When the second motor 8 starts, it drives the second gear 25 to rotate, and then drives the slide bar 11 to move laterally in a mirror image.

[0031] Furthermore, the clamping head 6 includes a support tube 17 and a fixing structure. The fixing structure is disposed on the support tube 17, the support tube 17 is rotatably disposed on the moving block 5, and one end of the support tube 17 extends to the inside of the moving block 5.

[0032] Furthermore, the bearing tube 17 extends into the interior of the moving block 5 and is equidistantly equipped with multiple sets of teeth 20. A motor 3 15 is fixedly installed on the bottom inner wall of the moving block 5, and a gear 16 is fixedly installed on the output shaft of the motor 3 15. The gear 16 meshes with the teeth 20. When the motor 3 15 starts, it drives the gear 16 to rotate, and then meshes to drive the bearing tube 17 to rotate. In this scheme, four sets of clamping heads 6 are set on each moving block 5. Therefore, when the bearing tube is fixedly installed inside each clamping head 6, each clamping head 6 can rotate independently and then be separated. Compared with the existing centrifuge equipment, which has multiple sets of circular holes on a disc to insert the bearing tube and then the disc ends, the independent rotation of each clamping head 6 in this device can keep its rotation center at the axial center point of the bearing tube, ensuring the centrifugation effect.

[0033] Furthermore, an annular internal groove 18 is provided on the inner wall of the circular hole on the movable block 5 for inserting the bearing tube 17, and an annular protrusion 19 is integrally formed on the bearing tube 17 at the position corresponding to the annular internal groove 18. The annular protrusion 19 and the annular internal groove 18 are rotatably engaged together.

[0034] Furthermore, the fixing structure includes multiple sets of rubber strips 22 and a threaded ring 23 threadedly installed on the top of the bearing tube 17. Multiple sets of strip-shaped openings 21 are equally spaced on the bearing tube 17. The rubber strips 22 are fixedly installed inside the strip-shaped openings 21. The upper and lower ends of the rubber strips 22 are fixedly installed on the upper and lower inner walls of the strip-shaped openings 21. Both sides of the rubber strips 22 located inside and outside the bearing tube 17 are rectangular. An inclined notch 24 is opened on the lower inner wall of the threaded ring 23. When it is necessary to fix the bearing tube, the bearing tube is inserted into the bearing tube 17. Then the threaded ring 23 is rotated and moves downward. Then the inclined inner wall of the inclined notch 24 is pressed against the arc-shaped outer wall surface of the rubber strips 22 located outside the bearing tube 17. Then it presses the rubber strips 22, and the rubber strips 22 deform towards the inner area of ​​the bearing tube 17 and then fits onto the bearing tube for compression and fixing.

[0035] Working principle: Material is injected into the inside of the carrier tube, and then the carrier tube is inserted into the inside of the carrier tube 17. Then, the threaded ring 23 is rotated and moves downward. Then, the inclined inner wall of the inclined notch 24 is squeezed against the arc-shaped outer wall surface of the rubber strip 22 located on the outside of the carrier tube 17. Then, it squeezes the rubber strip 22, and the rubber strip 22 deforms towards the inner area of ​​the carrier tube 17 and then adheres to the carrier tube for compression and fixation. The output shaft of motor 4 reciprocates and rotates, which then drives the cover plate 2 to swing. Motor 8 starts and drives gear 25 to rotate, which then drives the slide bar 11 to move laterally, which then drives the mounting plate 14 to move laterally, which then drives the moving block 5 to move. Motor 3 starts and drives gear 16 to rotate, which then meshes and drives the carrier tube 17 to rotate, thereby driving each carrier tube to rotate individually.

[0036] Structural Description: Casing 1 The outer shell 1 is the external frame of the entire high-wet high-protein starch gradient extraction and separation equipment, providing installation and protection space for the internal structures. A cover plate 2 is hinged to its opening, forming a relatively enclosed working environment, which can reduce material splashing or interference from external factors during the separation process.

[0037] Cover plate 2 The cover plate 2 is hinged to the opening of the outer casing 1, enabling opening and closing for easy placement and removal of components such as test tubes. The cover plate 2 has a rectangular opening with a transparent glass panel inside, allowing operators to observe the separation process inside the outer casing 1 without opening the cover plate 2.

[0038] Concave bearing plate 3 The concave support plate 3 is located inside the outer casing 1. Its main function is to support the moving blocks 5, the clamping head 6, and other structures, and it can swing to provide swinging motion for the separation process. Rotating shafts are fixedly installed on both sides of the plate, with one shaft connected to the output shaft of motor 4, enabling the swinging motion through the drive of motor 4. The concave support plate 3 also features a rack and pinion structure for driving the two moving blocks 5 to move laterally in a mirror image. A groove 9 is formed on its support surface, and a motor mounting base 7 is fixedly installed at the bottom.

[0039] Motor 14 Motor 4 is fixedly installed on one side of housing 1. Its output shaft extends through housing 1 into the housing and is connected to the rotating shaft on one side of concave support plate 3. When the concave support plate 3 needs to swing, the output shaft of motor 4 reciprocates, driving the concave support plate 3 to swing through the rotating shaft, which is the power source for the swing of the concave support plate 3.

[0040] Move block 5 The movable block 5 is mounted on the concave support plate 3 and can move laterally in a mirror manner under the drive of the rack and pinion structure. Each movable block 5 is provided with four sets of independently rotatable clamping heads 6 for mounting and supporting the clamping heads 6. The movable block 5 is fixedly connected to the mounting plate 14 and moves laterally by moving the mounting plate 14. The movable block 5 has a circular hole for inserting the support tube 17, and an annular internal groove 18 is formed on the inner wall of the circular hole. A motor 15 is fixedly mounted on the bottom inner wall.

[0041] Clamping head 6 The clamping head 6 is used to fix the carrier test tube, which is filled with starch material. It can rotate independently to achieve multi-angle centrifugation and ensure separation effect. The clamping head 6 includes a carrier tube 17 and a fixing structure. The carrier tube 17 is rotatably mounted on the moving block 5, and one end extends to the inside of the moving block 5. Multiple sets of teeth 20 are installed at equal intervals on the extended end.

[0042] Motor mounting bracket 7 The motor mounting base 7 is fixedly installed on the bottom of the concave bearing plate 3. Its main function is to install and fix the motor 8, provide a stable installation position for the motor 8, ensure that the motor 8 will not shake during operation, and ensure stable meshing between the gear 25 and the tooth 13.

[0043] Motor 28 Motor 28 is fixedly installed inside the motor mounting base 7, and its output shaft extends into the interior of the groove 9. Gear 25 is fixedly installed on the output shaft. Motor 28 is an important component of the motor structure in the rack and pinion structure. After starting, it drives gear 25 to rotate. Through the meshing of gear 25 with tooth 13, it drives the two slide bars 11 to move laterally in a mirror image inside the groove 9, which is one of the power sources for the lateral movement of the moving block 5.

[0044] Groove 9 The groove 9 is formed on the bearing surface of the concave bearing plate 3 to accommodate components such as the slide bar 11 and the motor structure, providing space for the lateral movement of the slide bar 11. An inner wall groove 10 is formed on its inner wall, which cooperates with the side protrusion 12 on the slide bar 11 to guide and limit the movement of the slide bar 11.

[0045] Inner wall groove 10 The inner wall groove 10 is formed on the inner wall of the groove 9 and is slidably engaged with the side protrusion 12 on the slider 11. During the lateral movement of the slider 11, the inner wall groove 10 restricts the movement trajectory of the side protrusion 12, thereby ensuring that the slider 11 can stably move laterally in a mirror image within the groove 9 and preventing the slider 11 from deviating.

[0046] Slider 11 Slide bars 11 are respectively disposed on both sides inside the groove 9, enabling mirror-like lateral movement within the groove 9. Multiple sets of teeth 13 are equidistantly installed on the side wall of the two slide bars 11 that are close to each other, meshing with gears 25 in the motor structure. A side protrusion 12 is integrally formed on the slide bar 11 corresponding to the position of the inner wall groove 10, and a mounting plate 14 is fixedly installed on the top of the opposite end. Driven by the motor 8, the slide bars 11 move, causing the mounting plate 14 and the moving block 5 to move.

[0047] 12 side protrusions The side protrusion 12 is integrally formed on the slide bar 11 at the position corresponding to the inner wall groove 10, and is slidably engaged with the inner wall groove 10. Its function is to guide and limit the movement of the slide bar 11 in conjunction with the inner wall groove 10, ensuring that the slide bar 11 moves stably along the set trajectory and preventing the slide bar 11 from shaking or falling out of the groove 9 during the movement.

[0048] Tooth 13 The first tooth 13 is equidistantly installed on the side wall of the two slide bars 11 that are close to each other, and meshes with the second gear 25 in the motor structure. When the second gear 25 rotates, it drives the two slide bars 11 to move laterally in a mirror image through the meshing transmission with the first tooth 13. It is an important transmission structure for realizing the movement of the slide bars 11.

[0049] Mounting plate 14 The mounting plate 14 is fixedly installed on the top of the two sliding bars 11 at opposite ends and is fixedly connected to the moving block 5. The mounting plate 14 moves laterally under the action of the sliding bars 11, thereby causing the moving block 5 connected to it to move laterally synchronously, thus serving to connect the sliding bars 11 and the moving block 5.

[0050] Motor 315 Motor 3 15 is fixedly installed on the bottom inner wall of the moving block 5, and gear 16 is fixedly installed on its output shaft. After motor 3 15 is started, it drives gear 16 to rotate. Through the meshing of gear 16 and tooth 20, it drives the bearing tube 17 to rotate, which is the power source for the rotation of the clamping head 6. Each clamping head 6 corresponds to a set of motor 3 15 to ensure that the clamping head 6 can rotate independently.

[0051] Gear 16 Gear 16 is fixedly mounted on the output shaft of motor 3 15 and meshes with tooth 20 on the bearing tube 17. When motor 3 15 starts, gear 16 rotates with the output shaft and transmits power from motor 3 15 to bearing tube 17 through meshing with tooth 20, causing bearing tube 17 to rotate. It is the transmission component for the rotation of bearing tube 17.

[0052] Bearing pipe 17 The support tube 17 is a component of the clamping head 6, rotatably mounted on the moving block 5. One end extends to the inner side of the moving block 5, with multiple sets of teeth 20 evenly spaced on the extended end. The other end is used to insert the support tube. An annular protrusion 19 is integrally formed on the support tube 17 at the position corresponding to the annular internal groove 18. Rotational connection is achieved through the engagement of the annular protrusion 19 and the annular internal groove 18. Multiple sets of strip-shaped openings 21 are evenly spaced on it for installing rubber strips 22, and a threaded ring 23 is threaded onto the top.

[0053] Annular internal groove 18 An annular internal groove 18 is formed on the inner wall of the circular hole on the movable block 5 for inserting the support tube 17, and is rotatably engaged with the annular protrusion 19 on the support tube 17. This structure supports and limits the rotation of the support tube 17, ensuring that the support tube 17 can rotate stably on the movable block 5 without axial displacement.

[0054] 19 ring-shaped protrusions The annular protrusion 19 is integrally formed on the support tube 17 at the position corresponding to the annular internal groove 18, and is rotatably engaged with the annular internal groove 18. During the rotation of the support tube 17, the annular protrusion 19 rotates within the annular internal groove 18, cooperating with the annular internal groove 18 to ensure the stability and smoothness of the rotation of the support tube 17.

[0055] Tooth 20 The second tooth 20 is equidistantly installed at one end of the bearing tube 17 extending into the moving block 5, and meshes with the first gear 16 on the output shaft of the third motor 15. When the first gear 16 rotates, it drives the bearing tube 17 to rotate through meshing with the second tooth 20, which is the transmission structure that enables the bearing tube 17 to obtain rotational power.

[0056] Strip opening 21 Strip-shaped openings 21 are equidistantly formed on the support tube 17 for installing rubber strips 22, providing installation space for the rubber strips 22. The upper and lower inner walls of the strip-shaped openings 21 are used to fix the upper and lower ends of the rubber strips 22, so that the rubber strips 22 can be stably installed on the support tube 17 and can deform into the inner region of the support tube 17 when compressed.

[0057] Rubber strip 22 The rubber strip 22 is fixedly installed inside the strip-shaped opening 21, with its upper and lower ends fixedly installed on the inner walls of the upper and lower sides of the strip-shaped opening 21. Both sides located inside and outside the bearing tube 17 are rectangular. When the threaded ring 23 is rotated, the inclined notch 24 at the lower end of the threaded ring 23 compresses the arc-shaped outer wall surface of the rubber strip 22 located outside the bearing tube 17, causing the rubber strip 22 to deform towards the inner region of the bearing tube 17, thereby adhering to the bearing tube and compressing and fixing the bearing tube.

[0058] Threaded ring 23 The threaded ring 23 is threaded onto the top of the bearing tube 17, and an inclined notch 24 is formed on the inner wall of its lower end. When it is necessary to fix the bearing tube, the threaded ring 23 is rotated to move it downward, and the rubber strip 22 is squeezed through the inclined inner wall of the inclined notch 24, causing the rubber strip 22 to deform and fix the bearing tube. It is an important part of the fixing structure and plays a role in adjusting and applying pressure.

[0059] Sloping gap 24 An inclined notch 24 is formed on the lower inner wall of the threaded ring 23, and its inner wall is inclined. When the threaded ring 23 moves downward, the inclined inner wall of the inclined notch 24 contacts the arc-shaped outer wall of the rubber strip 22 located outside the bearing tube 17 and generates compression, converting the downward movement of the threaded ring 23 into radial compression force on the rubber strip 22, causing the rubber strip 22 to deform.

[0060] Gear 25 Gear 25 is fixedly mounted on the output shaft of motor 8 and meshes with tooth 13 on slide bar 11. After motor 8 starts, it drives gear 25 to rotate. Through meshing with tooth 13, it drives the two slide bars 11 to move laterally in a mirror image inside the groove 9. It is the key component in the rack and pinion structure to realize power transmission.
