Abstract

The utility model discloses a synthetic reactor stirrer of trifluoro ethyl acetoacetate, including motor, reduction gear and (mixing) shaft, motor and reduction gear are equipped with the top of (mixing) shaft, be equipped with the two -stage agitator on the (mixing) shaft, be first agitator and second agitator respectively, first agitator and second agitator are three leaf impulse type agitators, certain inclination has between the stirring vane of first agitator and second agitator and the (mixing) shaft. The utility model discloses a three leaf impulse type agitators of two -stage, and certain inclination has between stirring vane and the (mixing) shaft, can drive the material and roll from top to bottom, improve the stirring rate to the material, and then accelerate heat transfer, mass transfer efficiency. The two -stage agitator sets up relatively, can mention the material better, strengthens the stirring dynamics to the material, improves stirring efficiency.

Description

A kind of trifluoroacetic ethyl acetoacetate synthesis reaction vessel agitator
Technical field
The utility model belongs to field of chemical equipment, is specifically related to a kind of trifluoroacetic ethyl acetoacetate synthesis reaction vessel agitator.
Background technology
Trifluoroacetic ethyl acetoacetate synthesis technique generally carries out in reactor, agitator is provided with in reactor, existing trifluoroacetic ethyl acetoacetate synthesis reaction vessel generally adopts anchor agitator, but the viscosity of sludge due to trifluoroacetic ethyl acetoacetate is not very large, adopt anchor agitator can not stir well feed liquid, affect the mixing of feed liquid, and then affect reaction effect.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of trifluoroacetic ethyl acetoacetate synthesis reaction vessel agitator, material can be gathered together better thus stir material fast, fully, improves stirring efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of trifluoroacetic ethyl acetoacetate synthesis reaction vessel agitator, comprise motor, decelerator and shaft, described motor and decelerator are provided with the top of shaft, described shaft is provided with two-stage agitator, be respectively the first agitator and the second agitator, described first agitator and the second agitator are three leaf propeller agitators, have certain inclination angle between the stirring vane of described first agitator and the second agitator and shaft.
Further, the inclination angle between described stirring vane and shaft is 10 °.
Further, described first agitator and the second agitator are oppositely arranged, and the inclination angle of described first agitator is downward, and the inclination angle of described second agitator upwards.
Further, described first agitator is left-handed three leaf propeller agitators, and described second agitator is dextrorotation three leaf propeller agitator.
Further, the diameter of the stirring vane of described first agitator and the second agitator is 1/3 of reactor internal diameter, and the distance of stirring vane and reactor inwall is 30-40cm.
The beneficial effects of the utility model are: adopt two-stage three leaf propeller agitator, and have certain inclination angle between stirring vane and shaft, material can be driven to roll up and down, improve the stirring rate to material, and then accelerate heat transfer, mass-transfer efficiency.Two-stage agitator is oppositely arranged, and can be mentioned by material better, strengthens the stirring dynamics to material, improves stirring efficiency.First agitator is left-handed, the second agitator is dextrorotation, and two agitator mixing directions are relative, also can increase the stirring dynamics to material, improve stirring efficiency further.
