Heptane is a kind of colourless volatile liquid, is commonly used for the standard of octane number determination, solvent, and for the preparation of organic synthesis, experiment reagent, therefore heptane is present in laboratory and chemical enterprise in a large number.When preparing heptane, usually all decompression distillation operation will be carried out, but existing vacuum distillation equipment structure is comparatively complicated, cause the raising of cost on the one hand, on the other hand due to the complex structure of equipment, cause the product after decompression distillation in a device the holdup time longer, easily polluted; And existing equipment is also not easy to dismounting cleaning.
Therefore, develop a kind of structure simple, be easy to dismounting cleaning, and can ensure that the vacuum distillation equipment of products pure is those skilled in the art institute urgent need to solve the problem.
Summary of the invention
For solving the problem, the invention discloses a kind of decompression distillation bottle for the preparation of heptane.
In order to achieve the above object, the invention provides following technical scheme:
A kind of decompression distillation bottle, comprises cucurbit and decompressor; The top of cucurbit connects decompressor by distillation pressure-reduction outlet; Decompressor comprises decompression cylinder and ram pot; Decompression cylinder is column, and its one end is provided with decompression cavity vertically; The internal slide of decompression cavity is provided with decompression slide bar, and the bottom of the cavity that reduces pressure radially is provided with pressure-reduction outlet; Pressure-reduction outlet is connected with distillation pressure-reduction outlet by relief pipe; One end of ram pot fixes with decompression cylinder, and the other end is fixed with hydraulic cylinder; Decompression slide bar is connected with hydraulic cylinder through ram pot.
The invention provides a kind of decompression distillation bottle, be made up of cucurbit and decompressor.
The top of the cucurbit in the present invention offers distillation pressure-reduction outlet, and distillation pressure-reduction outlet connects decompressor, is reduced pressure in cucurbit by decompressor.
Decompressor in the present invention is made up of the decompression cylinder of column and ram pot; One end of decompression cylinder is provided with decompression cavity vertically, and decompression cavity inside slides and is provided with decompression slide bar, and the bottom of decompression cavity is radially provided with pressure-reduction outlet, and pressure-reduction outlet is connected with distillation pressure-reduction outlet by relief pipe; One end of ram pot fixes with decompression cylinder, and other end connecting fluid cylinder pressure, hydraulic pressure slide bar is connected with hydraulic cylinder through ram pot.Hydraulic cylinder drives decompression slide bar to slide in decompression cavity, changes the pressure in cucurbit; When sliding to pressure-reduction outlet, increase the pressure of cucurbit; When sliding away from pressure-reduction outlet, reduce the pressure of cucurbit.
As preferably, the sidewall of ram pot has latasuture; Decompression cylinder is provided with scale strip to ram pot is parallel; One end that decompression slide bar is positioned at ram pot is connected with pointer; Pointer fits in the surface of scale strip through latasuture.
In the present invention, the sidewall of ram pot also has latasuture, and decompression cylinder is provided with scale strip towards ram pot is parallel, scale strip can show the pressure size in cucurbit; Decompression slide bar is positioned at one end concatenation pointer of ram pot, and pointer fits in scale strip surface through latasuture; The present invention marks the scale on scale strip by testing in advance, and the corresponding force value of each scale, when distilling, the scale observed on scale strip can know the pressure size in cucurbit.
As preferably, the outer surface of ram pot is evenly provided with La Erka; Decompression cylinder is provided with a circle groove near one end of ram pot; Groove matches with La Erka.
The present invention is evenly provided with La Erka at the outer surface of ram pot, and decompression cylinder is provided with groove with matching near one end of ram pot; Ram pot with La Erka forms male joint, and be with reeded decompression cylinder to form female joint, both are formed jointly " Earrings type snap joint ", utilize self-lock mechanism to be closely connected, and for convenience detachly clear up.
Compared with prior art, beneficial effect is in the present invention: (1) structure is simple, easy to use; (2) be convenient to regulate the pressure size in cucurbit; (3) decompressor is convenient to dismounting, to wherein cleaning, ensures the cleaning of product of distillation.
