Drier, the air inlet of the escape pipe are inserted in the desiccant layer, and the gas outlet of the air inlet pipe is arranged on desiccant layer
Outside.
Further, it is provided with air outlet valve on the escape pipe.
Further, it is provided with intake valve in the air inlet pipe.
Further, the anti-down cucurbitula is additionally provided with surge pipe, and pressure regulator valve, the surge pipe are provided with the surge pipe
Gas outlet insert in the desiccant layer.
Further, the gas outlet of the surge pipe is provided with filter.
Further, the air inlet of the escape pipe is provided with filter.
Further, the filter is filter paper or filter screen.
Further, the thickness of the drier is between the 1/3 to 2/3 of the anti-down cucurbitula cavity heights.
The utility model anti-suck vacuum extractor both can easily remove the micro volatile components in product, again may be used
Anti-suck, anti-steam, it is simple and practical.

Embodiment
The utility model is more fully illustrated below with embodiment.The utility model can be presented as it is a variety of not
Same form, it is not construed as being confined to the exemplary embodiment described here.
For ease of explanation, space relative terms such as " on ", " under " " left side " " right sides " can be used herein, for saying
The element or feature shown in bright figure is relative to another element or the relation of feature.It should be understood that except in figure
Outside the orientation shown, spatial terminology is intended to include the different azimuth of device in use or operation.If for example, in figure
Device is squeezed, be stated as positioned at other elements or feature " under " element will be located into other elements or feature " on ".Cause
This, exemplary term " under " both upper and lower orientation can be included.Device can be positioned otherwise（It is rotated by 90 ° or is located at
Other orientation）, can correspondingly be explained used herein of the relative explanation in space.
As shown in figure 1, the anti-suck vacuum extractor in the present embodiment, including vacuum pump using circulatory water（Not shown in figure）；
Suck-back device is additionally provided with the air inlet of vacuum pump using circulatory water, suck-back device is by air inlet pipe 5, escape pipe 2 and anti-suck
Tank is formed, and drier 4 is filled with anti-down cucurbitula, and drier should have certain thickness, form desiccant layer.Thickness preferably controls
Between the 1/3 to 2/3 of anti-down cucurbitula cavity heights.In the air inlet insertion desiccant layer of escape pipe 2, the outlet of air inlet pipe 5
Mouth is arranged on outside desiccant layer.Drier thickness is less than the 1/3 of anti-down cucurbitula cavity heights, and anti-suck effect is poor；Higher than anti-
The 2/3 of suck-back tank cavity heights can influence to adjust the effect of valve regulation evacuated pressure.
In order to facilitate the vacuum pressure of control system, air outlet valve 1 can be provided with escape pipe 2, by closing outlet
Pipe 2, improve the pressure of system.
In order to avoid the gas in system enter reagent container in, can be provided with intake valve 6 in air inlet pipe 5, so as to
When needed, cut-out reagent container and pumped vacuum systems contact in time.
Surge pipe 8 can also be set on anti-down cucurbitula, and pressure regulator valve 7 is set on surge pipe.The air inlet of surge pipe 8
Connect air；By adjusting pressure regulator valve 7, thus it is possible to vary the pressure differential at the both ends of pressure regulator valve 7, the pressure of anti-down cucurbitula inner chamber is carried out
Accurate control.The gas outlet of regulation surge pipe 8 should be inserted in desiccant layer；Vacuum pump using circulatory water is avoided to stop when vacuumizing,
Moisture in air enters reagent container.
In order to avoid causing drier to enter in surge pipe 8 due to pressure differential, pressure regulator valve 7 is blocked, can be in surge pipe 8
Gas outlet sets filter 3.
Similarly, also filter 3 should be set in the air inlet of escape pipe 2.
Filter 3 can be special filter core, can also easy filtering material, such as filter paper or filter screen.
When vacuumizing, vacuum pump using circulatory water produces vacuum.The air of anti-down cucurbitula inner chamber is logical through desiccant layer, filter 3
Cross escape pipe 2 and enter vacuum pump using circulatory water；The pressure of anti-down cucurbitula inner chamber reduces.Air in reagent container is from the quilt of air inlet pipe 5
Anti-down cucurbitula inner chamber is sucked, air is after the drying of drier 4, into escape pipe 2.When pressure is less than desired vacuum pressure,
Pressure regulator valve 7 can be opened, air is entered from surge pipe 8, after desiccant dryness, is supplemented in anti-down cucurbitula inner chamber, is lifted
The pressure of anti-down cucurbitula inner chamber.
When vacuum pump using circulatory water failure can not extract vacuum, because the air pressure in reagent container is relatively low；Water can volatilize, from
Escape pipe 2 backflows.Because gas of the part rich in moisture can be contacted first with drier, by after desiccant dehydration again through air inlet
Pipe 5 backflows such as reagent container, can effectively prevent moisture contamination reagent.Equally, the air with moisture enters anti-from surge pipe 8
During suck-back tank inner chamber, first it can also be contacted with drier, can by being backflowed again through air inlet pipe 5 such as reagent container after desiccant dehydration
Effectively to prevent moisture contamination reagent.
Filter 3 can not only avoid drier from entering escape pipe；When backflowing, cushioning effect can also be played, is avoided
The air blast of entrance dispels drier, so as to ensure drying effect.
In pumped vacuum systems failure, gas can be quickly blocked by closing air outlet valve 1, intake valve 6 and pressure regulator valve 7 in time
Stream；Avoid the quick decompression of reagent container.
The utility model anti-suck vacuum extractor both can easily remove the micro volatile components in product, again may be used
Anti-suck, anti-steam, it is simple and practical.
Above-mentioned example is only intended to illustrate the utility model, in addition, also a variety of different embodiments, and these
Embodiment be all those skilled in the art after comprehension the utility model thought it is also envisioned that therefore, no longer arrange one by one herein
Lift.
