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 and similar components, is difficult to separate, is a thermosensitive spice, has low distillation temperature, does not evaporate unnecessary fractions, has overhigh temperature, easily decomposes menthol which needs to be reserved, increases byproducts and has deep color, so as to prevent oil from decomposing, reduced pressure distillation is needed, a Roots vacuum pump is adopted in the prior art for vacuumizing, and the peppermint oil is easily foamed, so that liquid in a distillation kettle is easily flushed into a distillation column during boiling, vapor-liquid mass transfer is influenced, the technical problems are mainly caused by the following reasons, namely, the suction force of the existing vacuum pump is constant, the capacity of the distillation kettle is constant, the amount of air entering is increased when the feeding amount is increased, the vacuum pump cannot timely pump the menthol out, and bubbles easily gush into the distillation column after the liquid level in the distillation kettle is increased, so that the existing distillation column is required to be improved.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provides a peppermint oil distillation tower, wherein a rotary hollow sphere is arranged at the joint of the distillation tower and a distillation kettle, and the peppermint oil distillation tower cannot enter the distillation tower after bubbles are generated.
In order to achieve the technical effects, the technical scheme of the invention is as follows: the utility model provides a peppermint oil distillation column, includes distillation column body, roots vacuum pump, distillation column body and stills's junction is provided with rotatory piercing mechanism, rotatory piercing mechanism including fixed set up in the limiting plate of distillation column body bottom, the round hole has been seted up on the limiting plate, the top of limiting plate is provided with the fretwork spheroid, the spheroidal diameter of fretwork is greater than the diameter of round hole just fretwork spheroidal part passes the round hole, fretwork spheroidal both ends respectively with distillation column body's inside wall rotates to be connected, distillation column body's outside is provided with the drive fretwork spheroid pivoted asynchronous motor, fretwork spheroidal axis of rotation with the central line of round hole is mutually perpendicular, be provided with the current transformer who detects its electric current on the asynchronous motor, be provided with the converter on the roots vacuum pump, the current transformer with the controller of converter is connected mutually electricity.
Further improved is that the outer surface of the hollowed-out sphere is provided with a plurality of spike parts extending along the radial direction of the hollowed-out sphere.
Further improved is that the spike is needle-shaped or conical.
The further improvement is that the two ends of the hollowed-out sphere are respectively connected with the distillation tower body in a rotating way through a rotating joint.
Further improved is that the hollowed-out sphere is in a grid shape.
The invention has the advantages and beneficial effects that: firstly, the rotary hollow sphere is arranged at the joint of the distillation tower and the distillation kettle, after bubbles are generated, the hollow sphere which is rotated is intercepted and cannot enter the distillation tower, in addition, the spike part on the hollow sphere punctures the bubbles, peppermint oil is adhered to the hollow sphere, the whole weight of the hollow sphere is gradually heavier, the load of the asynchronous motor is increased, the current transformer transmits the detected current increasing signal to the frequency converter of the vacuum pump, and therefore the adsorption force of the vacuum pump is improved, and the generation of the bubbles is reduced.
