Description
Technical field
The utility model relates to one and vacuumizes two-stage cold-trap device, more particularly, relates to a kind of device for effectively removing coercibility component in gas in molecular clock.
Background technology
In the molecular clock process of thick dimeric dibasic acid, need the vacuum≤10Pa of whole system, therefore, need the vacuum pump set being equipped with large rate of air sucked in required, again due to the component of some coercibility in gas bleeding, need to adopt cold-trap device to be cooled the normal operation of removing guarantee vacuum pump set; And original cold-trap have employed the water-cooled mode of one-level cold-trap ice; be drawn out of a large amount of component in gas like this to separate out in cold-trap because frozen water temperature is too low; separate out material and be directly attached to the whole exhaust pipe of easy blocking and space on cooling tube; the process of palpus frequent shutdown, such cold-trap device must be improved the needs that could adapt to actual production.
Utility model content
For solving above technical problem, the technical solution of the utility model vacuumizes two-stage cold-trap device for providing one, this cold-trap device efficiently can catch the coercibility component in vacuum suction and it be shifted in time, thorough removal coercibility component, ensure that the long stable operation of vacuum system.
The technical solution of the utility model is:
One vacuumizes two-stage cold-trap device, comprise the molecular still, one-level cold-trap, secondary cold-trap and the vacuum pump set that are communicated with successively by suction catheters, the one-level cold-trap cooling tube longitudinally arranged is provided with in described one-level cold-trap, the secondary cold-trap cooling tube longitudinally arranged is provided with in described secondary cold-trap, be connected with one-level cold-trap condensation component basin bottom described one-level cold-trap, bottom described secondary cold-trap, be connected with secondary cold-trap condensation component basin.
Further, the water inlet pipe of described one-level cold-trap cooling tube and outlet pipe are separately positioned on the outside of described one-level cold-trap, the water inlet pipe of described secondary cold-trap cooling tube and outlet pipe are separately positioned on the outside of described secondary cold-trap, and the water inlet pipe of described one-level cold-trap cooling tube and secondary cold-trap cooling tube and outlet pipe are equipped with control valve.
Further, described one-level cold-trap condensation component basin and secondary cold-trap condensation component tank bottom are all connected with discharge pipe, and described discharge pipe is equipped with dump valve.
The beneficial effects of the utility model: what the utility model provided vacuumize two-stage cold-trap device efficiently can catch the coercibility component in vacuum suction and it be shifted in time, thoroughly remove coercibility component, ensure that the long stable operation of vacuum system.

Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
One shown in composition graphs 1 vacuumizes two-stage cold-trap device, comprise the molecular still 1, one-level cold-trap 2, secondary cold-trap 3 and the vacuum pump set 8 that are communicated with successively by suction catheters 14, the one-level cold-trap cooling tube 4 longitudinally arranged is provided with in described one-level cold-trap 2, the secondary cold-trap cooling tube 5 longitudinally arranged is provided with in described secondary cold-trap 3, be connected with one-level cold-trap condensation component basin 6 bottom described one-level cold-trap 2, bottom described secondary cold-trap 3, be connected with secondary cold-trap condensation component basin 7.
In the present embodiment, the water inlet pipe 9 of described one-level cold-trap cooling tube 4 and outlet pipe 10 are separately positioned on the outside of described one-level cold-trap 2, the water inlet pipe 9 of described secondary cold-trap cooling tube 5 and outlet pipe 10 are separately positioned on the outside of described secondary cold-trap 3, and the water inlet pipe 9 of described one-level cold-trap cooling tube 4 and secondary cold-trap cooling tube 5 and outlet pipe 10 are equipped with control valve 11.
In the present embodiment, be all connected with discharge pipe 12 bottom described one-level cold-trap condensation component basin 6 and secondary cold-trap condensation component basin 7, described discharge pipe 12 is equipped with dump valve 13.
The utility model provides one and vacuumizes two-stage cold-trap tandem arrangement, structure is simple, replace original one-level cold-trap, and one-level cold-trap 2 adopts room temperature water to cool now, secondary cold-trap 3 just adopts cold water to cool, because cooling range is moderate, in gas, coercibility component can be removed in time at twice and directly not invest on cooling tube, ensure that the long stable operation of vacuum system.
During concrete use, the gas that vacuum pump set 8 is extracted out is through one-level cold-trap 2, owing to adopting room temperature water to cool in cooling tube, the temperature difference is suitable for, and coercibility component rate of set is suitable for and can drops downwards in corresponding basin, again when secondary cold-trap 3 cools, because a large amount of coercibility component traps at one-level cold-trap 2, secondary cold-trap 3 is further deep cooling again, thoroughly eliminates remaining coercibility component, efficiently, stable.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement etc., all should be included within protection domain of the present utility model.
