The bidirectional refrigeration oil trapping baffle plate can prevent oil in a diffusion pump from entering a vacuum chamber and prevent oil in the vacuum chamber from entering the diffusion pump.
Description
Technical field
The utility model relates to vacuum equipment field, particularly relates to a kind of two-way system cold oil trapping baffle plate.
Background technique
Existing conventional cold apron can only prevent the unidirectional oil that returns, and, after refrigerated baffle is cooling, is converted into liquid state turns back in diffusion pump by gaseous state by the oil vapor molecule of diffusion pump or other pumping equipment.Space instrument must be under certain degree of vacuum, and the oil that need are injected is heated, and is vaporized, and the oil molecule after vaporization enters in product, thereby reaches requirement.
But this mode can produce many problems: one, oil vapor molecular moiety after vaporization enters in product, remaining enters diffusion pump after refrigerated baffle refrigeration, because of diffusion pump different with institute oiling saturation vapour pressure, therefore diffusion pump has been produced to pollution, degree of vacuum can decline rapidly, and diffusion pump performance has been caused to certain destruction.Its two, diffusion pump through pollution after, ultimate vacuum can not reach the required requirement of product, need clean diffusion pump or molecular pump, has so both delayed the manufacture cycle, has wasted again resource.Especially, diffusion pump, after repeatedly dismantling, could use after need to ressembling, and this just makes producer molecular pump need to be sent back to manufacturer's maintenance.
Model utility content
Based on this, for existing oil vapor molecule, diffusion pump is polluted, and affect the problem of ultimate vacuum, be necessary to propose a kind ofly can prevent that the oil in diffusion pump from entering vacuum chamber, the oil of vacuum chamber enters the two-way system cold oil trapping baffle plate of diffusion pump.
The technical solution of the utility model is: a kind of two-way system cold oil trapping baffle plate, comprise leakproof oil cap, coolant transport tube, baffle plate shell and be positioned at described baffle plate enclosure and spiral oil baffle, described coolant transport tube extends to the inner side of described baffle plate shell through described baffle plate shell, described oil baffle comprises the upper oil baffle and the lower oil baffle that are distribution up and down, angle between upper oil baffle and lower oil baffle is less than 180 °, on described upper oil baffle and described lower oil baffle, be welded with respectively upper cooling copper tube and lower cooling copper tube with its Spiral distribution, the end that is connected in described coolant transport tube and is positioned at described baffle plate shell inner side is all converged in one end of described upper cooling copper tube and one end of described lower cooling copper tube, the below correspondence of described lower oil baffle is provided with spiral helicine oil sump tank, described oil sump tank bottom is provided with honeycomb duct, described oil sump tank is communicated with described honeycomb duct, on described honeycomb duct, evenly have oil strain hole.
Oil baffle and cooling copper tube are used in conjunction with, and by coolant, can easily carry out cooling to the oil vapor molecule that enters baffle plate enclosure.Oil collecting pipe and honeycomb duct are used in conjunction with, and cooled oil vapor molecule can be collected.
In an embodiment, described baffle plate shell inner bottom surface is provided with accumulator therein, and described accumulator below is provided with the valve with accumulator internal communication.Oil sump tank can be collected becoming liquid oil vapor molecule after cooling, after shutdown, discharges by valve.
The beneficial effects of the utility model are: can reach and prevent that diffusion pump oil from entering vacuum chamber, can prevent that again the oil vapor of vacuum chamber from entering diffusion pump, with this reach to oil vapor cooling, trapping, store.Can not pollute diffusion pump or molecular pump like this, ensure the ability of the long-term continuous operation of equipment, and save a large amount of man power and materials.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Embodiment:
As shown in Figure 1, a kind of two-way system cold oil trapping baffle plate, comprise leakproof oil cap 8, coolant transport tube 6, baffle plate shell 3 and be positioned at the inner and spiral oil baffles of described baffle plate shell 3, described coolant transport tube 6 extends to the inner side of described baffle plate shell 3 through described baffle plate shell 3, described oil baffle comprises the upper oil baffle 1 and the lower oil baffle 2 that are distribution up and down, angle between upper oil baffle 1 and lower oil baffle 2 is less than 180 °, on described upper oil baffle 1 and described lower oil baffle 2, be welded with respectively upper cooling copper tube 9 and lower cooling copper tube 10 with its Spiral distribution, the end that is connected in described coolant transport tube 6 and is positioned at described baffle plate shell 3 inner sides is all converged in one end of one end of described upper cooling copper tube 9 and described lower cooling copper tube 10, the below correspondence of described lower oil baffle 2 is provided with spiral helicine oil sump tank 4, described oil sump tank 4 bottoms are provided with honeycomb duct 5, described oil sump tank 4 is communicated with described honeycomb duct 5, on described honeycomb duct 5, evenly have oil strain hole.
In the present embodiment, described baffle plate shell 3 inner bottom surfaces are provided with accumulator 7, and described accumulator 7 belows are provided with the valve with accumulator 7 internal communication.
Described two-way system cold oil trapping baffle plate is assemblied between diffusion pump or molecular pump and high vacuum valve.Owing to being placed on the workpiece of vacuum chamber because technological requirement need to become gaseous state from liquid state by particular oils after heating to be injected in workpiece, but unnecessary part is due to differential pressure action, enters from top to bottom this face trapping refrigeration baffle plate.When oil vapor molecule touches while being injected into the cooling oil baffle 1 of the cooling copper tube 2 of cooling liquid, become rapidly liquid flow to oil sump tank 4 from gaseous state, then flow to honeycomb duct 5 through the opening of oil sump tank 4 bottoms.Then, the oil in honeycomb duct 5 flows to accumulator 7 and stores.After shutdown, open valve, emit oil.
The above embodiment has only expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
