Description

Technical Field

[0001] This utility model is applicable to cyclodextrin production, and more specifically to raw material screening, relating to a raw material screening device for cyclodextrin production. Background Technology

[0002] Cyclodextrins are a collective term for a series of cyclic oligosaccharides formed from amylose by cyclodextrin glucosyltransferase produced by Bacillus subtilis. They typically contain 6–12 D-glucanose units. Among these, molecules containing 6, 7, and 8 glucose units, respectively, are the most studied and of significant practical importance, referred to as alpha-, beta-, and gama-cyclodextrins. X-ray diffraction, infrared spectroscopy, and nuclear magnetic resonance spectroscopy have confirmed that each D(+)-glucanose unit in a cyclodextrin molecule has a chair conformation. Each glucose unit is linked by a 1,4-glycosidic bond to form a ring. Because the glycosidic bonds connecting the glucose units cannot rotate freely, cyclodextrins are not cylindrical molecules but rather slightly conical rings.

[0003] Cyclodextrin is produced from amylose. Before production, the amylose needs to be screened to remove particulate impurities, improve its fineness, and prevent particulate amylose from affecting the production effect of cyclodextrin.

[0004] However, existing screening devices generally use shaking or reciprocating motion to screen amylose, which causes amylose to splash and easily leads to dangerously high air concentrations. Utility Model Content

[0005] One objective of this invention is to provide a new technology solution for a raw material screening device for cyclodextrin production.

[0006] According to a first aspect of the present invention, a raw material screening device for cyclodextrin production is provided, comprising a screening shell, a power mechanism provided on one side of the screening shell, a screening mechanism provided inside the screening shell, and the screening mechanism being connected to the power mechanism;

[0007] The power mechanism includes a servo motor and a long shaft. A first rotating wheel is keyed to the output shaft of the servo motor. Eccentric wheels are provided at both ends of the long shaft. A second rotating wheel is connected to one side of one of the eccentric wheels. A transmission belt is drivingly connected to the first rotating wheel and the second rotating wheel.

[0008] The screening mechanism includes a screening plate mounted on the long shaft, and a crushing roller is movably installed inside the screening plate.

[0009] Furthermore, a mounting plate is welded to one side of the screening shell, the servo motor is fixedly mounted on the mounting plate, and eccentric wheels are eccentrically mounted at both ends of the long shaft.

[0010] Furthermore, a first auxiliary wheel is provided on one side of the screening housing near the second rotating wheel, and a second auxiliary wheel is provided on both sides of the screening housing near the first rotating wheel. The transmission belt is sequentially wound around the first rotating wheel, the second rotating wheel, the first auxiliary wheel, and the second auxiliary wheel.

[0011] Furthermore, the screening plate has through holes at both ends, the long shaft is movably installed inside the through holes, and the bottom of the screening plate has several screening holes at equal intervals.

[0012] Furthermore, elongated slots are provided on both sides of the screening plate, and a connecting shaft is provided inside the crushing roller. The two ends of the connecting shaft are movably located inside the elongated slots, and limiting plates are fixedly provided at both ends of the connecting shaft.

[0013] Furthermore, the screening housing is provided with elastic mechanisms at both ends, the elastic mechanisms including contact plates, the lower ends of the contact plates being provided with elastic parts, and the elastic parts having connecting plates on both sides for fixed connection to the inner wall of the screening housing.

[0014] Furthermore, two support legs are welded to each end of the screening shell, a material collection hood is welded to the lower part of the screening shell, and a discharge pipe is welded to the middle of the lower part of the material collection hood.

[0015] The beneficial effects of this utility model are:

[0016] In use, this utility model uses a servo motor to drive the first rotating wheel, which is eccentrically set on both sides, to rotate. When the first rotating wheel is driven, it can drive the screening plate. The two ends of the screening plate are driven by the first rotating wheel to raise one end and lower the other end, thus completing the screening of the amylose in the screening plate and eliminating the particles in the amylose from affecting the subsequent reaction.

[0017] Furthermore, the connecting shaft is movably mounted inside the screening plate via elongated slots. When the screening plate is tilted, the connecting shaft rolls inside the slots, allowing the crushing rollers on the connecting shaft to crush the amylose particles during rolling, thus assisting in the screening of amylose. Additionally, an elastic mechanism is provided inside the screening shell to provide elastic support for the screening plate. The vibration of the elastic part can cause slight shaking at the bottom of the screening shell, facilitating the removal of amylose and improving the screening process.

It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0029] like Figures 1-4 As shown, a raw material screening device for cyclodextrin production includes a screening shell 1, a power mechanism 2 on one side of the screening shell 1, a screening mechanism 3 inside the screening shell 1, and the screening mechanism 3 connected to the power mechanism 2.

[0030] The power mechanism 2 includes a servo motor 201 and a long shaft 203. The output shaft of the servo motor 201 is keyed to a first rotating wheel 202. The two ends of the long shaft 203 are respectively provided with eccentric wheels 204. One side of one eccentric wheel 204 is connected to a second rotating wheel 209. The first rotating wheel 202 and the second rotating wheel 209 are connected by a transmission belt 206.

[0031] The screening mechanism 3 includes a screening plate 301 mounted on a long shaft 203, and a crushing roller 306 is movably installed inside the screening plate 301.

[0032] In this embodiment, preferably, a mounting plate 205 is welded to one side of the screening shell 1, a servo motor 201 is fixedly mounted on the mounting plate 205, and eccentric wheels 204 are eccentrically mounted at both ends of the long shaft 203.

[0033] It should be noted that the mounting plate 205 is designed to install and fix the servo motor 201, ensuring its stability during operation. The eccentric wheels 204, which are eccentrically mounted at both ends of the long shaft 203, facilitate the lifting and lowering adjustment of the end of the screening plate 301, thereby enabling the screening of amylose.

[0034] In this embodiment, preferably, a first auxiliary wheel 208 is provided on one side of the screening housing 1 near the second rotating wheel 209, and a second auxiliary wheel 207 is provided on both sides of the screening housing 1 near the first rotating wheel 202. The transmission belt 206 is sequentially wound around the first rotating wheel 202, the second rotating wheel 209, the first auxiliary wheel 208, and the second auxiliary wheel 207.

[0035] It should be noted that by setting the first auxiliary wheel 208 and the second auxiliary wheel 207, the transmission belt 206 can be connected to the first rotating wheel 202 and the second rotating wheel 209, thereby increasing the transmission wrap angle between the transmission belt 206 and the first rotating wheel 202 and the second rotating wheel 209, so that the first rotating wheel 202 can transmit power to the second rotating wheel 209 through the transmission belt 206.

[0036] In this embodiment, preferably, the two ends of the screening plate 301 are respectively provided with through holes 302, the long shaft 203 is movably installed inside the through holes 302, and the bottom of the screening plate 301 is provided with a plurality of equally spaced screening holes 303.

[0037] It should be noted that the through hole 302 is designed to facilitate the connection between the long shaft 203 and the sieve plate 301, and to facilitate the lifting and adjustment control of the sieve plate 301. That is, the lifting and adjustment of the end of the sieve plate 301 is achieved by driving the eccentrically mounted eccentric wheel 204, so as to achieve the sieving of amylose. The setting of the sieve hole 303 is also designed to facilitate the sieving of amylose.

[0038] In this embodiment, preferably, the screening plate 301 has elongated slots 304 on both sides, the crushing roller 306 has a connecting shaft 305 inside, the two ends of the connecting shaft 305 are movably inside the elongated slots 304, and the two ends of the connecting shaft 305 are respectively fixed with limiting plates 307.

[0039] It should be noted that the elongated slot 304 is designed to install the connecting shaft 305, so that when the screening plate 301 is raised at one end, the connecting shaft 305 drives the crushing roller 306 to roll towards the lowering end under the action of gravity. During the rolling, the crushing roller 306 crushes the amylose particles and facilitates the amylose to fall through the screening hole 303. The limiting plate 307 is designed to prevent the connecting shaft 305 from falling off.

[0040] In this embodiment, preferably, elastic mechanisms 4 are fixedly provided at both ends of the inner side of the screening shell 1. The elastic mechanism 4 includes a contact plate 403. Elastic parts 402 are fixedly provided at the lower ends of both ends of the contact plate 403. Connecting plates 401 for fixed connection to the inner wall of the screening shell 1 are provided on both sides of the elastic parts 402.

[0041] It should be noted that the elastic mechanism 4 is set to achieve micro-shaking of the screening plate 301, so that the screening plate 301 can shake slightly during the lifting and adjusting process, which facilitates the screening of amylose. The connecting plate 401 is used for fixed installation, and the contact plate 403 is used to contact the screening plate 301. The elastic part 402 provides elastic adjustment to achieve screening of amylose.

[0042] In this embodiment, preferably, two support legs 7 are welded to both ends of the screening shell 1, a material collection hood 5 is welded to the lower part of the screening shell 1, and a material discharge pipe 6 is welded to the middle of the lower part of the material collection hood 5.

[0043] It should be noted that the support legs 7 at both ends are designed to fix and support the screening shell 1, maintaining its balance and stability, while the collection hood 5 and the discharge pipe 6 are designed to discharge the screened amylose.

[0044] The specific operational procedures for this application are as follows:

[0045] In use, amylose is first fed onto the screening plate 301 in the screening mechanism 3. Then, the servo motor 201 in the power mechanism 2 is started. The operation of the servo motor 201 drives the transmission belt 206, which in turn drives the second rotating wheel 209 to rotate. The second rotating wheel 209 drives the eccentric wheel 204 to rotate, which in turn drives the eccentric wheel 204 and the long shaft 203 to rotate. When the long shaft 203 is eccentrically set, it can drive the screening plate 301 to adjust, so that one end of the screening plate 301 is raised while the other end is lowered, thus tilting the screening plate 301. When the screening plate 301 is tilted, under the action of gravity, the connecting shaft 305 and the crushing roller 306 can roll from the raised end to the lowered end, thereby crushing the particles in the amylose.

[0046] An elastic mechanism 4 is provided inside the screening housing 1. When one end of the screening plate 301 descends, one end of the screening plate 301 is attached to the connecting plate 401. At this time, the force-bearing elastic part 402 vibrates, so that the screening plate 301 can generate continuous slight vibration, which is convenient for cooperating with the crushing roller 306 to screen the amylose.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
