Description

Technical Field

[0001] This utility model relates to the field of reactor cleaning technology, specifically to an acid spraying cleaning device for a modified starch reactor. Background Technology

[0002] To improve starch properties and expand its applications, physical, chemical, or enzymatic treatments are used to introduce new functional groups into starch molecules or alter starch molecule size and granule properties. This changes alter the natural characteristics of starch (such as gelatinization temperature, thermal viscosity and its stability, freeze-thaw stability, gelling power, film-forming properties, and transparency) to better suit specific application requirements. This type of modified starch, after secondary processing, is collectively called modified starch. After producing modified starch, the reaction vessel is typically cleaned using acid washing.

[0003] Most existing reactors for preparing modified starch are fixed in shape. However, acid washing and cleaning require rotating and letting stand for a period of time after the acid solution is injected. At this time, the reactor needs to be adjusted to a horizontal angle. However, a horizontally placed reactor is not convenient for starch to be discharged, and a vertically oriented reactor is not conducive to acid cleaning. This has certain inconveniences in actual use. Utility Model Content

Most existing modified starch preparation reaction vessels are in a fixed form, and acid cleaning requires rotating and standing for a period of time after the acid is injected. At this time, the reaction vessel needs to be adjusted to a horizontal angle.

[0020] Example 1: Please refer to Figure 1 - Figure 3 A modified starch reactor acid spray cleaning device includes a fixed frame 1 and support legs 2 fixedly installed at the four corners of the lower end of the fixed frame 1. A reactor assembly 3 is movably installed inside the fixed frame 1. Threaded grooves 13 are opened on both side walls of the fixed frame 1. Fixed rods 4 are rotatably installed in the threaded grooves 13. A connecting ring 41 is rotatably installed between the two fixed rods 4. The reactor assembly 3 includes a reactor body 31 fixedly installed in the connecting ring 41. A sliding groove 42 is opened on the side wall of the connecting ring 41. One end of the fixed rod 4 is slidably connected in the sliding groove 42. Movable components 5 are movably installed on both sides of the fixed frame 1.

[0021] In this embodiment: When cleaning the reactor body 31 after using the device, the two fixing rods 4 on both sides can be rotated. The fixing rods 4 slide outward along the threaded groove 13. When the fixing rods 4 move outward, they slide outward along the sliding groove 42 towards the outside of the connecting ring 41. The fixing rods 4 can be rotated to a position where they do not contact the connecting ring 41. During the movement of the fixing rods 4, both the connecting ring 41 and the reactor body 31 become movable. At this time, the reactor assembly 3 can be rotated along the fixing rods 4 to adjust from a vertical state to a horizontal state. At this time, the acid spraying cleaning work can be completed with the cooperation of the movable assembly 5. In actual use, the orientation angle of the reactor body 31 of this modified starch reactor acid spraying cleaning device can be changed. When it is necessary to prepare modified starch, it can be set vertically downward. When it is necessary to clean its interior, it can be rotated to a horizontal angle. It is simple to operate and flexible to use.

[0022] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 4 The fixed frame 1 has limit grooves 11 on both sides of its lower end, and a feeding groove 12 is provided at the lower end of the fixed frame 1. The movable component 5 includes a connecting plate 51 that is slidably connected in the limit groove 11. Movable plates 52 are fixedly installed on the sides of the connecting plate 51. The movable plates 52 can move on both sides of the fixed frame 1.

[0023] Fixed plates 14 are fixedly installed on both sides of the fixed frame 1, and springs 15 are fixedly installed on both sides of the fixed plates 14. The other end of the springs 15 is fixedly connected to the side wall of the movable plate 52, and the springs 15 can provide inward pulling force to the movable plate 52.

[0024] A motor 53 is fixedly installed on the inner wall of one of the movable plates 52. A connecting groove 54 is opened at the output end of the motor 53. A discharge pipe 32 is provided at one end of the reactor body 31. A sealing cap 33 is threaded on the discharge pipe 32. A feed inlet 34 is provided on one side of the reactor body 31.

[0025] A cleaning component 6 is rotatably installed inside the feed inlet 34. The cleaning component 6 includes a movable tube 61 threadedly installed inside the feed inlet 34. A connecting block 62 is fixedly installed on one side of the movable tube 61. The connecting block 62 is slidably connected in the connecting groove 54. Several slots 63 are equidistantly opened on one side of the movable tube 61. A movable ring 64 is rotatably installed on the outside of the slots 63. The movable ring 64 is rotatably positioned on the outside of the slots 63.

[0026] A guide tube 65 is fixedly installed on the outer side of the movable ring 64. Several mounting slots 66 are equally spaced on the movable tube 61. Movable blocks 67 are rotatably installed in each mounting slot 66. Nozzles 68 are fixedly installed on each movable block 67. Springs 69 are fixedly installed between the two sides of the movable block 67 and the side wall of the mounting slot 66. The springs 69 allow the movable block 67 to move when it is squeezed, and after the movement, the springs 69 can push it to a central vertical angle.

[0027] In this embodiment: When the device needs to be cleaned internally by acid spraying, first, the fixing rods 4 on both sides are rotated to release the fixing limit on the connecting ring 41 and the reactor body 31. At this time, the reactor body 31 can be rotated to the angle shown in the figure. During this process, the two sides of the reactor body 31 contact the output end of the motor 53 respectively. At this time, the movable plate 52 can be pulled outward until the connecting block 62 slides into the connecting groove 54 to complete the connection between the motor 53 and the movable tube 61. At this time, the motor 53 can be started. The motor 53 starts and drives the cleaning component 6 at its output end and the reactor component 3 to rotate together. During this process, the acid cleaning solution can be injected into the interior of the reactor body 31 through the feed pipe 65. The acid cleaning solution enters the movable ring 64 through the feed pipe 65 and then enters the groove 63. Inside the movable tube 61, the cleaning component is ultimately sprayed outward through nozzles 68 on multiple movable blocks 67 to acid wash and clean the inner wall of the reactor body 31. When it is necessary to remove the cleaning component 6, the reactor body 31 can be adjusted to a vertical angle, and then the movable tube 61 can be rotated to pull it outward as a whole. During the movement, the movable block 67 will contact the side wall of the reactor body 31 and be squeezed and rotated into the mounting groove 66. After contact, it can return to its original position under the action of spring 69. When using this device, the movable component 5 on the side facilitates the connection between the output end of the motor 53 and the cleaning component 6. When it is necessary to disconnect, the movable plate 52 can be pulled outward to release the connection between the two. The adjustment is simple and convenient, and the cleaning component 6 can be disassembled and cleaned as needed.
