Compared with the prior art, the utility model discloses simple structure, convenient to use, manufacturing cost are than lower.
Description
Technical field
The utility model relates to PLA production technical field, is specifically related to a kind of lactide rapid condensation crystallization apparatus.
Background technology
In PLA preparation process, the lactide that Pfansteihl mixture Pintsch process generates is a kind of rough lactide, the inside is containing a large amount of impurity, therefore need to carry out reaction further by rough that lactide is refined, carry out at lactide needing condensation process in the process of refining, and traditional condensation process is too slow, operating efficiency is lower.
Utility model content
The purpose of this utility model is to provide the lactide rapid condensation crystallization apparatus that a kind of structure is simple, easy to use, manufacturing cost is lower.
For achieving the above object, the utility model provides following technical scheme:
A kind of lactide rapid condensation crystallization apparatus, comprise condenser pipe, interior pipe, outlet pipe, storage tank, water pump, water inlet pipe, condensation entrance and condensate outlet, pipe in installing in condenser pipe, condenser pipe upper end connects condensate outlet, and condenser pipe lower end connects condensation entrance, and condensation entrance connects water inlet pipe, condensate outlet connects outlet pipe, outlet pipe connects storage tank upper end, and water inlet pipe connects storage tank lower end, and storage tank side connects water pump.
As the further improvement of above-mentioned technology, described interior pipe adopts copper product to make.
As the further improvement of above-mentioned technology, described condenser pipe carries out slant setting.
Compared with prior art, the beneficial effects of the utility model are: interior pipe adopts copper product to make, because copper has good thermal conductivity, condensation work fast and effectively can be carried out, condenser pipe carries out slant setting, add condensation effect, the utility model structure is simple, easy to use simultaneously, manufacturing cost is lower.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: pipe, 3-outlet pipe, 4-storage tank, 5-water pump, 6-water inlet pipe, 7-condensation entrance, 8-condensate outlet in 1-condenser pipe, 2-.
Detailed description of the invention
Be described in more detail below in conjunction with the technical scheme of detailed description of the invention to this patent.
A kind of lactide rapid condensation crystallization apparatus, comprise condenser pipe 1, interior pipe 2, outlet pipe 3, storage tank 4, water pump 5, water inlet pipe 6, condensation entrance 7 and condensate outlet 8, condenser pipe 1 carries out slant setting, increase condensation effect, pipe 2 in installing in condenser pipe 1, interior pipe 2 adopts copper product to make, be convenient to carry out condensation fast, condenser pipe 1 upper end connects condensate outlet 8, condenser pipe 1 lower end connects condensation entrance 7, condensation entrance 7 connects water inlet pipe 6, condensate outlet 8 connects outlet pipe 3, the outlet pipe 3 that condensate outlet 8 connects connects storage tank 4 upper end, the water inlet pipe 6 that condensation entrance 7 connects connects storage tank 4 lower end, storage tank 4 side connects water pump.
During utility model works, start water pump 5, water inside storage tank 4 is by water inlet pipe 6, arrive condensation entrance 7, water enters condenser pipe 1 from condensation entrance 7, pipe 2 in installing in condenser pipe 1, interior pipe 2 adopts copper product to make, pure lactide steam is passed in interior pipe 2, due to the thermal conductive resin of copper and under the effect passing through cold water in condenser pipe 1 outside copper pipe, be liquid by the rapid cooling down of pure lactide steam, thus reach the object of rapid condensation crystallization, the condensate outlet 8 that water in condenser pipe 1 after heat absorption passed through condenser pipe 1 upper end flows into outlet pipe 3, and finally flow back to storage tank 4, thus reach the object recycled.
The foregoing is only preferred embodiment of the present invention; not thereby embodiments of the present invention and protection domain is limited; to those skilled in the art; the equivalent replacement that all utilizations description of the present invention and diagramatic content are made and the scheme that apparent change obtains should be recognized, all should be included in protection scope of the present invention.
