Abstract
Description
Technical Field
[0001] The utility model relates to the field of sorbitol processing equipment, in particular to a reaction kettle for sorbitol production. Background Art
[0002] Sorbitol is a sugar alcohol that can be metabolized slowly by humans. It has a similar structure to monosaccharides and can be obtained by reducing the aldehyde group on glucose to hydroxyl. It is mainly used as a sweetener with a refreshing sweet taste and a sweetness of about half that of sucrose. Its calorific value is similar to that of sucrose. It can also be used as a chemical raw material and is often used in the food and pharmaceutical industries. In order to ensure the production efficiency and product quality of sorbitol, it is necessary to use a reactor to process it during production. The reactor provides high temperature and high pressure reaction conditions to promote the chemical reaction in the sorbitol synthesis process and make the reaction more sufficient and rapid.
[0003] Currently, in the sorbitol production process, the activity of the catalyst inside the reactor will gradually decrease over time, causing the chemical reaction rate to slow down, and it will take a longer time for sorbitol to complete the reaction. At this time, the catalyst needs to be taken out from the reactor, and the activity of the catalyst needs to be restored through heating, reduction, and oxidation process operations, and then it needs to be put into the reactor again. During such operations, the catalyst is lost a lot during the process of loading, removing, and regenerating the catalyst, and the regeneration process takes a long time, affecting normal production efficiency.
[0004] Therefore, it is necessary to provide a new sorbitol production reactor to solve the above-mentioned technical problems. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a reaction kettle for sorbitol production.
[0006] The sorbitol production reactor provided by the utility model comprises a reaction device for producing and processing sorbitol, a feeding pipeline is arranged on one side of the reaction device, and a packing device is arranged on one end of the feeding pipeline;
[0007] The filling device includes an installation box, a driving assembly and a rotating disk. The installation box is fixed to the end of the feeding pipe away from the reaction equipment, a material storage box is fixedly provided on the top of the installation box, the bottom of the driving assembly is fixedly connected to the bottom end of the inner wall of the installation box, the center of the bottom of the rotating disk is fixedly connected to the top of the driving assembly, a feeding hole is provided on the surface of the rotating disk, a feeding pipe is provided at the bottom end of the inner wall of the material storage box, and the bottom of the feeding pipe is in contact with the top of the rotating disk, and the end of the feeding pipe away from the reaction equipment is in contact with the bottom of the rotating disk.
[0008] Preferably, the diameter of the discharge pipe is smaller than the diameter of the discharge hole opened on the surface of the rotating disk, and the diameter of the feeding pipe is larger than the diameter of the discharge hole opened on the surface of the rotating disk.
[0009] Preferably, a feeding pipe is provided on the top of the material storage box.

[0012] Preferably, a protective cover is provided on the top of the rotating disk.
[0013] Compared with the related art, the reactor for sorbitol production provided by the utility model has the following beneficial effects:
[0014] Through the precise control of the driving component, the rotating disk can be driven to rotate inside the installation box. When the discharge hole opened on the surface of the rotating disk coincides with one end of the feeding pipe at the bottom, the alkali inside the storage box will fall into the feeding pipe through the discharge hole and enter the reactor through the feeding pipe, so that the alkali can contact the catalyst inside the reactor and regenerate the catalyst according to the regeneration steps. With the above structure, there is no need to take the catalyst out of the reactor when regenerating the catalyst, which can reduce the loss of the catalyst to a certain extent, shorten the time required for the catalyst regeneration process, and ensure normal production efficiency.

[0020] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

Figure 1 ; Figure 3 The cross-sectional structure of the reactor for sorbitol production provided by the utility model is shown in FIG. Figure 2 ; Figure 4 for Figure 3 The schematic diagram of the structure of the driving assembly and the rotating disk is shown.
[0022] In the specific implementation process, Figure 1-Figure 4 As shown, a reactor for sorbitol production comprises a reaction device 1 for producing and processing sorbitol, a feeding pipe 2 is arranged on one side of the reaction device 1, a packing device is arranged at one end of the feeding pipe 2, the packing device comprises a mounting box 3, a driving assembly and a rotating disk 4, the mounting box 3 is fixed to the end of the feeding pipe 2 away from the reaction device 1, a material storage box 6 is fixedly arranged on the top of the mounting box 3, the bottom of the driving assembly is fixedly connected to the bottom end of the inner wall of the mounting box 3, the center of the bottom of the rotating disk 4 is fixedly connected to the top of the driving assembly, a feeding hole 7 is arranged on the surface of the rotating disk 4, a feeding pipe 8 is arranged at the bottom end of the inner wall of the material storage box 6, and the bottom of the feeding pipe 8 is fitted with the top of the rotating disk 4, the end of the feeding pipe 2 away from the reaction device 1 is fitted with the bottom of the rotating disk 4, the caliber of the feeding pipe 8 is smaller than the caliber of the feeding hole 7 opened on the surface of the rotating disk 4, the caliber of the feeding pipe 2 is larger than the caliber of the feeding hole 7 opened on the surface of the rotating disk 4, a feeding pipe 9 is arranged on the top of the material storage box 6, and alkali is added to the inside of the material storage box 6 through the feeding pipe 9;
[0023] The driving assembly includes a motor 10, a support column 11 and a first gear 12. The bottom of the motor 10 is fixedly connected to the bottom end of the inner wall of the installation box 3, the output shaft of the motor 10 is fixedly connected to the bottom of the first gear 12, the bottom of the support column 11 is movably connected to the bottom end of the inner wall of the installation box 3, and a second gear 13 is provided on the top of the support column 11. The top of the second gear 13 is fixedly connected to the bottom of the rotating disk 4, and the second gear 13 is meshed with the first gear 12. A protective sleeve 5 is provided on the top of the rotating disk 4. The protective sleeve 5 provided on the top of the rotating disk 4 prevents the alkali from sliding from the top of the rotating disk 4 into the installation box 3. Because the added alkali is in granular form, when the discharge hole 7 opened on the surface of the rotating disk 4 does not overlap with the feeding pipe 2, the alkali will not flow to the outside of the lower feeding pipe 8 due to sealing problems.
[0024] The working principle provided by the utility model is as follows: because the bottom end of the inner wall of the storage box 6 is inclined, the alkali inside the storage box 6 will move to the top of the lower feeding pipe 8, and fall to the top of the rotating disk 4 through the lower feeding pipe 8. Through the precise control of the motor 10, the first gear 12 can be driven to rotate. Because the first gear 12 is meshed with the second gear 13, the rotation of the first gear 12 will drive the second gear 13 to rotate, and the rotating disk 4 is driven to rotate through the second gear 13. When the discharge hole 7 opened on the surface of the rotating disk 4 coincides with one end of the feeding pipe 2, the alkali inside the discharge pipe 8 will fall into the feeding pipe 2 through the discharge hole 7, and enter the reactor through the feeding pipe 2, so that the alkali can contact the catalyst inside the reactor. Because the diameter of the discharge pipe 8 is smaller than that of the discharge hole 7, and the diameter of the feeding pipe 2 is larger than that of the discharge hole 7, the alkali can be discharged more smoothly, and the blockage of the pipeline can be reduced.
