Description

Technical Field

[0001] This utility model relates to the field of cyclodextrin production technology, specifically to a feeding assembly and a centrifuge for cyclodextrin production. Background Technology

[0002] Cyclodextrin is a general term for a series of cyclic oligosaccharides produced from linear starch under the action of cyclodextrin glucosyltransferase produced by Bacillus. During the research and development of high-purity cyclodextrin mixture liquefaction, after the reactants have fully reacted, cyclodextrin crystals will precipitate. These crystals need to be centrifuged and filtered by an automatic centrifuge and collected for subsequent processing. Therefore, a feeding assembly and a centrifuge for cyclodextrin production are required.

[0003] Although the existing feeding components and centrifuges for cyclodextrin production have many beneficial effects, the following problems still exist: In actual use, cyclodextrin may contain other impurities, and if materials need to be added midway, the entire cover plate needs to be opened, which is cumbersome and can easily affect work efficiency. Secondly, in actual use, hydraulic cylinders are mostly used to drive the opening of the cover plate, but long-term use of hydraulic cylinders can easily lead to wear and unstable closure, which can easily affect the sealing effect during centrifugation.

[0032] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0033] This utility model provides an overall structural schematic diagram of a feeding assembly and a centrifuge for cyclodextrin production according to one embodiment, including:

[0034] Please see Figures 1-5 This utility model provides a technical solution:

[0035] A feeding assembly and a centrifuge for cyclodextrin production include a housing 1. A cover plate 2 is connected to the top of the housing 1 via bearings, facilitating the opening and closing of the cover plate 2. An arc groove 5 is formed on the surface of the cover plate 2, and a groove 51 is formed on the inner wall of the arc groove 5. An arc plate 52 is slidably connected to the inner wall of the groove 51. The arc plate 52 slidably connects to the groove 51, facilitating quick feeding of material into the housing 1 through the arc groove 5 after the arc plate 52 is opened. A handle 53 is fixed to the top of the arc plate 52, facilitating the movement of the arc plate 52. A transverse groove 59 is formed on the inner wall of the arc groove 5, and the arc plate 52 is slidably connected to the inner wall of the transverse groove 59. The transverse groove 59 slidably connects to the arc plate 52, facilitating the movement of material into the housing 1 through the arc groove 5. The area of ​​the plate 52 closes the arc groove 5, reducing the possibility of affecting the sealing performance of the equipment. The surface of the arc plate 52 is provided with a slot 54. The inner circumference of the slot 54 is fitted with a pin 55, and the outer circumference of the pin 55 is fitted with multiple plates 57. The surface of the plates 57 is welded with a spring 56. The surface of the cover plate 2 is provided with a vertical groove 58. The inner circumference of the vertical groove 58 matches the outer circumference of the plates 57. The top of the inner circumference of the vertical groove 58 is fixed with a plate 57. With the help of the spring 56 and the elastic force, the outer circumference of the pin 55 can stay in the vertical groove 58 or be fixed at the bottom of the slot 54, thereby achieving the purpose of fixing the arc plate 52 to the inner wall of the horizontal groove 59. This facilitates the sealing of the arc groove 5, thereby maintaining the sealing effect during the centrifugation process.

[0036] It is worth noting that, in order to reduce the possibility of displacement of the fixing plate 66 on the inner wall of the fixing block 6, specifically, the top of the box 1 has multiple fixing blocks 6 arranged in a ring by bolts. The fixing plate 66 is sleeved on the inner circumference of the fixing block 6, and the slider 62 is fixed on the outer circumference of the fixing plate 66. The outer circumference of the fixing block 6 has a groove 61, and the slider 62 is slidably connected to the groove 61. By using the slider 62 to slide and connect to the groove 61, the slider 62 can be fixed on the inner wall of the groove 61, thereby reducing the possibility of displacement of the fixing plate 66 on the inner wall of the fixing block 6.

[0037] Next, in order to reduce the occurrence of the cover plate 2 popping open, specifically, a circular groove 63 is provided on the inner wall of the slide groove 61, and a spring 64 is welded to the inner wall of the circular groove 63. A cylinder 65 is welded to one end of the spring 64. The outer circumference of the cylinder 65 matches the inner circumference of the circular groove 63. The elastic force of the spring 64 drives the cylinder 65 to fix the slider 62, thereby facilitating the fixation of the slider 62's specific position and reducing the occurrence of the cover plate 2 popping open.

[0038] Meanwhile, in order to maintain smoothness during the opening process, a fixing pin 67 is fixedly provided on the top of the fixing plate 66, and a fixing groove 68 is provided on the top of the cover plate 2. The inner wall of the fixing groove 68 matches the outer circumferential wall of the fixing pin 67. Through the design that the inner diameter of the fixing groove 68 matches the outer diameter of the fixing pin 67, it is convenient that when the cover plate 2 is opened after rotating the fixing plate 66, the fixing pin 67 will drive the fixing plate 66 to rise together, thereby facilitating the smoothness of the opening process.

[0039] Furthermore, in order to perform centrifugation on cyclodextrin, a centrifugation mechanism 3 is fixedly installed inside the housing 1, and a sealing plate 4 is fixedly installed at the bottom of the cover plate 2. The outer circumferential wall of the sealing plate 4 is in contact with the inner circumferential wall of the centrifugation mechanism 3, so that the centrifugation on cyclodextrin can be easily performed through the centrifugation mechanism 3.

[0040] The centrifuge mechanism 3 mentioned above can be found in document CN212759159U.

[0041] It is worth noting that, in order to reduce the possibility of impurities falling into the centrifuge and affecting processing, the bottom of the cover plate 2 is provided with an installation groove 510. The inner circumference of the installation groove 510 is threaded with an installation block 511. The side wall of the installation block 511 is fixed with a filter screen 512. The filter screen 512 is fixed by connecting the installation block 511 to the installation groove 510, which facilitates the filtration of raw materials and reduces the possibility of impurities falling into the centrifuge and affecting processing, thereby affecting product quality.

[0042] Finally, in order to complete the feeding operation, the feeding assembly specifically includes an arc groove 5, an arc plate 52, a handle 53, a slot 54, a pin 55, a spring 56, a plate 57, a vertical groove 58, a horizontal groove 59, a mounting groove 510, a mounting block 511, and a filter screen 512. The feeding operation is facilitated by the cooperation between the parts included in the feeding assembly.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-5 The feeding assembly and centrifuge for cyclodextrin production according to this embodiment are used in the following specific process:

[0045] 1: When using this type of feeding assembly and centrifuge for cyclodextrin production, the operator moves the housing 1 to a suitable position, opens the cover plate 2 using the bearing, puts the cyclodextrin to be processed into the centrifuge structure, and closes the cover plate 2 so that the sealing plate 4 fits against the inner circumference of the centrifuge mechanism 3. At this time, the fixing plate 66 will fall onto the inner circumference of the fixing block 6 as the cover plate 2 rotates. At this time, the operator can rotate the fixing pin 67 on the inner wall of the fixing groove 68 so that the slider 62 can be slidably connected to the inner wall of the groove 61 and is locked by the force of the spring 64 and the cylinder 65 provided on the inner wall of the circular groove 63. This reduces the phenomenon of the cover plate 2 popping open by using the elastic force, which is beneficial to better maintaining the sealing effect of the device during use.

[0046] 2: When the device needs to perform preliminary filtration of the input raw materials, the operator can pull the locking pin 55, causing the spring 56 to drive the locking plate 57 to move. After the locking pin 55 disengages from the inner wall of the locking groove 54 and stops at the inner wall of the vertical groove 58, the operator can use the handle 53 to push the arc plate 52, causing one end of the arc plate 52 to slide away from the inner wall of the horizontal groove 59, while the other end of the arc plate 52 slides against the inner wall of the groove 51. At this time, it is convenient for the operator to add raw materials to the centrifuge through the arc groove 5, which helps to save time and improve work efficiency.

[0047] 3: When the device has been used for a long time and there are a lot of impurities inside the filter screen 512, the operator can rotate the mounting block 511 to remove the filter screen 512 for cleaning by using the threaded method to remove the inner wall of the granulation mounting groove 510. This facilitates the filtration of raw materials and reduces the possibility of impurities falling into the centrifuge and affecting the processing, thereby affecting the product quality.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
