Description
Technical Field
The invention relates to menthol processing, in particular to a peppermint oil distillation tower.
Background
The natural peppermint crude oil has more components, similar properties of the components and difficult separation of glue, is a heat-sensitive spice, has over-low distillation temperature, does not evaporate unnecessary fractions, has over-high temperature, easily decomposes menthol needing to be kept, increases byproducts and has dark color, reduced pressure distillation is needed for preventing oil decomposition, a Roots vacuum pump is adopted for vacuumizing treatment in the prior art, in addition, because peppermint oil is easy to foam, liquid in a distillation kettle is easily flushed into a distillation tower column when boiling, and vapor-liquid mass transfer is influenced, so the technical problems are mainly caused by the following reasons that firstly, the suction force of the existing vacuum pump is constant, the capacity of the distillation kettle is constant, when the feeding amount is increased, the amount of air entering is increased, the vacuum pump cannot timely pump the liquid, and bubbles easily flow into the distillation tower after the liquid level in the distillation kettle is increased, there is therefore a need for improvements to existing distillation columns.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a peppermint oil distillation tower.
In order to realize the technical effects, the technical scheme of the invention is as follows: a peppermint oil distillation tower comprises a distillation tower body and a Roots vacuum pump, wherein a rotary puncturing mechanism is arranged at the joint of the distillation tower body and a distillation kettle, the rotary puncturing mechanism comprises a limiting plate fixedly arranged at the bottom of the distillation tower body, a round hole is formed in the limiting plate, a hollowed-out ball body is arranged above the limiting plate, the diameter of the hollowed-out ball body is larger than that of the round hole, the part of the hollowed-out ball body penetrates through the round hole, two ends of the hollowed-out ball body are respectively and rotatably connected with the inner side wall of the distillation tower body, an asynchronous motor for driving the hollowed-out ball body to rotate is arranged on the outer side of the distillation tower body, the rotating axial lead of the hollowed-out ball body is perpendicular to the central line of the round hole, a current transformer for detecting the current of the asynchronous motor is arranged on the asynchronous motor, the current transformer is electrically connected with the controller of the frequency converter.
The further improvement is that the outer surface of the hollow sphere is provided with a plurality of spine parts extending along the radial direction of the hollow sphere.
In a further improvement, the spine part is needle-shaped or conical.
The further improvement is that two ends of the hollow sphere are respectively connected with the distillation tower body in a rotating way through rotating joints.
The further improvement is that the hollow sphere is in a grid shape or a grid shape.
The invention has the advantages and beneficial effects that: at first, utilize rotatory fretwork spheroid to set up in the junction of distillation column and stills, in the unable distillation column that gets into of being intercepted by rotatory fretwork spheroid after the gassing, in addition, the spine portion on the fretwork spheroid pierces the adhesion of back peppermint oil on the fretwork spheroid with the bubble, cause the whole weight of fretwork spheroid to become heavy gradually, asynchronous machine's load has increased its electric current grow from this, current transformer transmits the electric current big signal that detects for the converter of vacuum pump, improve the adsorption affinity of vacuum pump from this, thereby reduce the production of bubble.
