Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a high and low temperature reaction kettle. Background Art

[0002] A reactor is a device used for chemical reactions, which usually consists of a sealed container and a related control system. Reactors are generally used in laboratories or industries for various chemical reactions, synthesis, analysis and other experiments. A high and low temperature reactor refers to a reactor with a temperature regulating device installed inside. It usually consists of a high temperature circulation device (such as a high temperature oil bath) and a low temperature circulation device (such as a cold water circulator). The reactor usually has heating and cooling functions inside, and high and low temperature cycles can be achieved by controlling the heating source and cooling source.

[0003] In order to ensure that the chemical reaction solvent and reactants inside the existing high and low temperature reactor are heated or cooled evenly during use, a stirring device is installed inside the reactor. However, the stirring device inside the reactor is relatively simple, and generally stirring is performed through a stirring shaft and stirring blades at the center. This stirring method will cause the chemical solvent and reactants inside the reactor to move regularly after stirring for a period of time. Therefore, the chemical solvent located outside the temperature regulating device and the chemical solvent at the center will not easily approach the temperature regulating device, and the uniformity of cooling or heating the chemical solvent is reduced, further reducing the reaction rate of the chemical solvent and reactants inside the reactor. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high and low temperature reactor, which solves the problem that the stirring device inside the traditional high and low temperature reactor drives the chemical solvent to rotate regularly inside the reactor, while improving the uniformity of heating or cooling the chemical solvent and improving the reaction efficiency of the chemical solvent and the reactants.

Starting the driving motor 3 can drive the driving shaft 11 to rotate relative to each other through the gear set 10, thereby facilitating the transfer of the chemical solvent at the bottom of the reactor 1 to the top of the reactor 1.

[0022] As a technical optimization solution of the utility model, a filter cover 701 is provided on the outer side of the rotating shaft 9, and the lower end of the filter cover 701 is fixedly connected to the upper surface of the filter mesh plate 7, which can filter the chemical solvent to remove impurities in the chemical solvent and avoid affecting the reaction between the chemical solvent and the reactant.

[0024] As a technical optimization scheme of the utility model, the transmission mechanism includes a transmission bevel gear I1201 and a transmission bevel gear II1202, and the transmission bevel gear I1201 and the transmission bevel gear II1202 are arranged vertically to each other, the upper surface of the transmission bevel gear I1201 is fixedly connected to the lower end of the rotating shaft 9 through a rotating shaft passing through the transmission box 12, the transmission bevel gear II1202 is fixedly connected to the side surface of the driving shaft 11, and the transmission bevel gear I1201 is meshingly connected with the transmission bevel gear II1202, which can simultaneously drive the driving shaft 11 and the rotating shaft 9 to rotate.
