Description

Technical Field

[0001] The utility model relates to the field of calcium methylbutyrate production, in particular to a cooling device for calcium methylbutyrate production. Background Art

[0002] The preparation method of β-hydroxy-β-methylbutyric acid calcium salt (HMB-Ca) belongs to the technical field of organic compound preparation. 4-methyl-4-hydroxy-2-pentanone (diacetone alcohol) is used as the reaction raw material, water is used as the solvent, and a NaOBr aqueous solution is used for haloform reaction, followed by acidification and isobutanol extraction. The HMB acid in the isobutanol extract is directly salted with Ca(OH)2 to obtain HMB-Ca. This method has the advantages of high product purity and low environmental pollution. The existing calcium methylbutyrate needs to be heated and kept between 65°C and 70°C when reacting in the reactor.

[0003] According to the published patent 202322416696.3, a reactor cooling device includes: an equipment table, a cooler and a reactor, a cooler is installed on one side of the top of the equipment table, a reactor is installed on the top of the equipment table close to the cooler, a cooling box is installed on the outer surface of the reactor, a water inlet pipe is installed at the bottom of the cooler, a water inlet pump is installed in the middle of the water inlet pipe, the outer surface of the water inlet pipe is connected to the bottom of the cooling box through a water inlet branch pipe, a return pipe is installed on the top of the cooler, and the outer surface of the return pipe is connected to the top of the cooling box through a return water branch pipe. A reactor cooling device solves the problem that the existing reactor cooling device uses an outer shield to cool the reactor as a whole, and in the heat exchange process, the heat exchange efficiency of the heat exchange medium is reduced after a long time of conduction, which is very likely to affect the overall heat exchange effect of the reactor, and the heat exchange efficiency of the heat exchange medium is improved, thereby improving the overall heat exchange effect of the reactor. In the process of realizing the utility model, the inventor finds that at least the following problems in the prior art have not been solved. Although three cooling boxes are arranged on the outer surface of the reactor to perform split heat exchange on the reactor, the problem that the existing reactor cooling device uses an outer shield to cool the reactor as a whole, in the heat exchange process, the heat exchange efficiency of the heat exchange medium is reduced after a long time of conduction, which is very likely to affect the overall heat exchange effect of the reactor, and the heat exchange efficiency of the heat exchange medium is improved, thereby improving the overall heat exchange effect of the reactor, but during use, in the process of cooling the reactor by the traditional cooling device, the heat exchange mechanism is generally arranged on the outer wall of the reactor body to cool the reactor body from the outside. This cooling method does not have a good cooling effect on the center position of the reaction material, resulting in uneven cooling effect. Therefore, it is necessary to design a new technical solution. Utility Model Content

During the cooling process, the motor 205 can also be turned on, and the motor 205 drives the motor shaft 209, and the motor shaft 209 drives the first gear 210. The first gear 210 drives the second gear 211, and the second gear 211 drives the rotating tube 202 and the stirring tube 208 to rotate. The rotating tube 202 rotates through two rotating joints to stir the reaction materials in the reactor body 1, so that the reaction materials are cooled in the process of uniformly stirring the reaction materials, which improves the uniformity of cooling the reaction materials and solves the problem that the traditional cooling device generally sets the heat exchange mechanism on the outer wall of the reactor body 1 during the cooling of the reactor, and cools the reactor body 1 from the outside. This cooling method is not very effective for the center position of the reaction materials, resulting in a technical problem of uneven cooling effect.

[0023] For details, see Figure 1 The two pump bodies 206 are respectively a liquid suction pump and a liquid intake pump.

[0024] For further information, see Figure 2 A motor 205 is installed on one side of the top of the reactor body 1, and a motor shaft 209 is connected to the bottom of the motor 205. The bottom of the motor shaft 209 extends into the reactor body 1, and a first gear 210 is fixed to one end of the motor shaft 209 located in the reactor body 1. A second gear 211 is meshed with one side of the first gear 210. A rotating tube 202 penetrates the inside of the second gear 211, and the rotating tube 202 is fixedly connected to the penetration position of the second gear 211.

[0025] It is worth noting that see Figure 1One end of a support rod 101 is fixed to both sides of the bottom of the first cooling box 201 and both sides of the top of the second cooling box 204 , and the other end of the support rod 101 is fixed to the reactor body 1 .

[0026] It is worth noting that see Figure 3 Semiconductor refrigeration sheets 3 are installed at the front ends of the first cooling box 201 and the second cooling box 204, and the cold ends of the semiconductor refrigeration sheets 3 are in contact with the front ends of the first cooling box 201 and the second cooling box 204. Since semiconductor refrigeration sheets 3 are arranged at the front ends of the two cooling boxes, and the cold ends of the semiconductor refrigeration sheets 3 are in contact with the surfaces of the cooling boxes, the coolant inside the cooling boxes is directly cooled, thereby avoiding the coolant from heating up during the circulation process and affecting the cooling effect of the reaction materials.

The cooling liquid will enter the stirring tube 208 and extend to different positions inside the reaction material, thereby cooling the reaction materials at different positions. During the cooling process, the motor 205 can also be turned on, and the motor 205 drives the motor shaft 209, and the motor shaft 209 drives the first gear 210, and the first gear 210 drives the second gear 211, and the second gear 211 drives the second gear 211. The rotating tube 202 and the stirring tube 208 are driven to rotate. The rotating tube 202 will rotate through two rotating joints to stir the reaction materials in the reactor body 1, so that the reaction materials are cooled in the process of uniformly stirring the reaction materials, thereby improving the uniformity of cooling the reaction materials. Since semiconductor refrigeration plates 3 are arranged at the front ends of the two cooling boxes, and the cold ends of the semiconductor refrigeration plates 3 are attached to the surfaces of the cooling boxes, the coolant inside the cooling boxes is directly cooled, thereby avoiding the coolant from heating up during the circulation process and affecting the cooling effect of the reaction materials.
