Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid sodium methoxide production, and particularly relates to an electrically-controlled liquid sodium methoxide production system. BACKGROUND

[0002] Liquid sodium methoxide is a colorless or slightly yellow viscous liquid, sensitive to oxygen, flammable and explosive, and extremely hygroscopic. Sodium methoxide is mainly used in pesticide production and oil processing industry, and is also widely used in perfume, dye and other industries when used as an analytical reagent. At present, the production of liquid sodium methoxide mainly includes sodium method preparation and alkali method preparation. The sodium method preparation refers to that liquid sodium methoxide is synthesized from metallic sodium and methanol; and the alkali method preparation refers to that liquid sodium methoxide is synthesized from sodium hydroxide and methanol.

[0003] When preparing liquid sodium methoxide, sodium hydroxide and methanol solution need to be mixed and stirred. The mixing and stirring equipment in the prior art is usually driven to rotate by a shaft to realize stirring. For example, a liquid sodium methoxide mixing device disclosed in the patent CN 215783033 U is driven by a push rod motor to rotate clockwise and counterclockwise to realize stirring. Another example is a stirring device and a powerful mixer disclosed in the patent CN 215742927 U, which changes the included angle between the stirring part and the connecting part to realize the stirring and mixing effect of the stirring blade. These are all driven to rotate by a shaft to realize stirring action, and the rotation direction needs to be realized by controlling the motor, that is, the stirring direction needs to be changed when the machine is stopped, and online adjustment cannot be realized. Moreover, the stirring can only be realized within the stirring radius, and the upper and lower parts cannot be stirred, which is prone to have local stirring dead angles. SUMMARY

[0004] Based on the existing technical problems, the present application provides an electrically-controlled liquid sodium methoxide production system.

[0019] Through the technical scheme, the driving groove is circumferentially provided at one-third, which can prevent excessive contact with the turbine to cause invalid action.

[0020] Preferably, the outer surface of the shaft sleeve close to the driving groove is further provided with a sealing ring for preventing the liquid sodium methoxide from leaking.

[0021] Through the technical scheme, the sealing ring can prevent the liquid sodium methoxide from entering the gap, thereby bringing inconvenience to cleaning.

[0022] Preferably, a mounting groove is formed on the wall thickness of the riser along the vertical direction, an inner wall of the mounting groove is slidably connected with a rack, a tooth groove is formed on the outer surface of the shaft sleeve and engaged with the rack, and the rack drives the shaft sleeve to rotate circumferentially after moving up and down in the mounting groove.

[0024] Preferably, the liquid sodium methoxide drives one of the forward turbine and the reverse turbine to rotate, thereby driving the stirring shaft to rotate.
