Description
Technical field
The utility model is related to sublimation purification technologies, and in particular to a kind of laboratory Decompression Sublimation purifying plant.
Background technology
Necessary device of the sublimation apparatus as refined product in a kind of fine chemical industry, is to pass through the crude product of compound
Heating sublimation evaporates and cooling two processes of crystallization of sublimating, to improve the purity of compound.But the other sublimation apparatus of technical grade without
Method meets the requirement that the requirement of laboratory chemical reagent purity is stringent, production batch is small.It is suitable as laboratory currently on the market
In sublimation apparatus, crude product rises to condenser and is cooled into crystal and is attached to condenser outer surface after being evaporated by evaporator, but
Due to constantly sublimating in the peeling of partial crystals on condenser, can be caused under gravity and fall to evaporator for crystal
In mixed with raw material.
For above-mentioned technological deficiency, Chinese patent CN204952338U discloses " a kind of separate type sublimation apparatus ", the dress
The evaporator set not on same vertical line, can produce the chemical reagent for the operation purification that needs to distil in batches with receiver.Though
The right patent solves above-mentioned crystal and peels off the technical problem into raw material, and still, there are complicated, heat loss for the device
Greatly, it needs to carry out heat preservation operation at evaporator and receiver junction and steam channel, it is of high cost, especially for testing
Room is in use, to buy the cost of equipment higher, and parts are all specific shape structures, poor universality, and maintenance and repair is of high cost.
Invention content
In order to solve the deficiencies in the prior art, the utility model, which provides one kind, to utilize laboratory existing apparatus to assemble
Plain type laboratory Decompression Sublimation purifying plant.
The technical solution of the utility model is：A kind of laboratory Decompression Sublimation purifying plant, including a spherical condensation tube, with
And the decompression air exhaust head and evaporative flask being connected respectively with the spherical condensation tube, the inlet and outlet of the spherical condensation tube
It is connected with condensate water circulatory system.
Further improvement of the utility model includes：
The evaporative flask is the aryballos of double side walls.
In the ground of spherical condensation tube top, the bulb condensation pipe end is nested in evaporation the decompression air exhaust head set
In bottle ground, the spherical condensation tube and the inside of evaporative flask junction are filled with column insulating glass wool.
Through-hole is offered at the outer rim of the column insulating glass wool.
Vertically open up fluted at the outer rim of the column insulating glass wool, the groove is in condenser pipe inner tubal wall
It surrounds to form through-hole structure.
The advantageous effect that the utility model can generate：The utility model often completes letter by laboratory with fexible unit
The structure of easy pressure relief sublimation device, simple in structure, spherical condensation tube is in one together with decompression air exhaust head and evaporative flask in device
On vertical line, condensation efficiency is high.Meanwhile diameter of Spherical Volume in spherical condensation tube and its inner wall are increasing crystallization area and heat exchange
While area, since its curved inner wall structure also adds the adhesive force of crystallization.

Specific implementation mode
It elaborates below in conjunction with the accompanying drawings to the utility model.
A kind of laboratory Decompression Sublimation purifying plant, including a spherical condensation tube, and respectively with the spherical condensation tube
The inlet and outlet of connected decompression air exhaust head and evaporative flask, the spherical condensation tube are connected with condensate water circulatory system.
The evaporative flask is the aryballos of double side walls, and the decompression air exhaust head set is embedded in spherical condensation tube top, described
Bulb condensation pipe end is nested in container connection ground, and the spherical condensation tube is internally provided with column with evaporative flask junction
Shape insulating glass wool.The structure can improve heat insulation effect, it is ensured that condensation-crystallization is completed inside condenser pipe.
The spherical condensation tube is internally provided with column insulating glass wool with evaporative flask junction, and the column keeps the temperature glass
Through-hole is offered at the outer rim of glass cotton.The structure design can ensure, when purification amount is larger, to utilize the heat preservation glass of column structure
Glass cotton can prevent the crystal generated from falling into evaporator downwards, increase the loaded area of crystallization；And in column mineral wool
Through-hole is offered at outer rim, i.e., opens up through-hole along the inner tubal wall of condenser pipe, can ensure the marginalisation of steam stream.It is taken out in decompression
Under the collective effect of heating device below device of air and evaporative flask, sample vapors gush upwards along narrow through-hole.First, energy
Enough ensure that steam climbs upwards along condenser pipe inner tubal wall, condensation-crystallization is attached to the ball of spherical condensation tube after carrying out heat exchange as early as possible
In shape tube wall；Second, when purify out crystallization content it is big when, since the specific structure of spherical condensation tube spherical inner wall can prevent most knots
Brilliant object falls off vertically downward along tube wall；Third, even if partially crystallizable falls off, and the vortex formed above through-hole can ensure to take off
The crystallization fallen is fallen on column mineral wool.
Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
