Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, in particular to a cyclohexanone processing device. Background Art

[0002] Cyclohexanone is an organic compound, a saturated cyclic ketone with a carbonyl carbon atom in a six-membered ring. It is a colorless, transparent liquid with an earthy smell. When it contains trace amounts of phenol, it has a minty smell. The impurities are light yellow, and the color changes with the storage time. It is water white to grayish yellow, has a strong pungent odor, and is extremely explosive when mixed with air. It is the same as open-chain saturated ketones. Distillation is a thermodynamic separation process. It uses the different boiling points of the components in a mixed liquid or liquid-solid system to evaporate the low-boiling component, and then condense it to separate the entire component. It is a unit operation process that combines the two unit operations of evaporation and condensation.

[0003] The existing cyclohexanone processing lacks a stirring structure for the solution during distillation. The solution is simply added to the distiller for distillation and heating, which has low heating efficiency, and further makes the volatilization efficiency of the liquid into gas low, reducing the distillation efficiency.

[0004] The prior art discloses a patent with a publication number of CN214714457U, which includes a distillation box, a stirring device is arranged inside the distillation box, a liquid inlet hole is opened on the left side of the upper surface of the distillation box, and an air outlet hole is opened on the right side of the upper surface of the distillation box. The distillation device specially used for processing cyclohexanone can achieve all-round stirring of liquids of different depths by setting a first rotating wheel and a second rotating wheel of different heights and a first connecting rod and a second connecting rod of different lengths, so that the stirring effect is more uniform.

[0005] As the existing technologies including the above patents are used, their shortcomings are gradually exposed, mainly in the following aspects:

[0006] First, during the reaction of cyclohexanone, the stirring device needs to be cleaned or replaced regularly. The existing stirring device of the cyclohexanone reactor is mainly fixed on a rotating device, and the disassembly and assembly process is complicated when cleaning or replacing it.

[0007] First, the liquid volume of the existing cyclohexanone reactor is not fixed, but the stirring device is fixed. When too much solution is added, the stirring device cannot be used for stirring, which affects the reaction rate.

[0008] In summary, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
