Description
Technical field
The utility model is related to a kind of scanning device for filter leaks detection and mobile mechanisms.
Background technology
In the air for needing high efficiency particulate air filter (such as efficiency particulate air (HEPA) filter or other high efficiency particulate air filters)
In ventilating system, it is known to use filter housing, in filter housing, filter unit is fixed and is pressed from both sides by effectively machinery
Tightly, respective filter unit is sealed in filter housing.High efficiency filter is sealed using such machine clamping mechanism
When device, it is necessary that ensure that any bypass or leakage around sealing are permeated less than the maximum of filter.It is also necessary that really
The filter surfaces for saving portion from damage do not have any pin hole leak or other defect.The technology is in the B.6 section of such as ISO14644-3
It is described.In national standard, such as in the Chinese Industrial Standards (CIS) that bio-safety is vented HEPA filtration facilities, also specify similar
And tightened up test.It can be as the single-point at filter rear average (single point average) or by close to mistake
Filter surface scans to be tested.Former approach need filter rear be more than sampled at 20 pipe diameters with
Ensure that single sample is thoroughly mixed, and although later approach is preferred and more acurrate, but need close to filter table
The washer in face and surrounding.If fan is placed on filter rear to generate negative pressure, close to the latter of surface scan
Process is actually more impossible.Any close access and reduction that will be opened air and enter pipeline to filtration zone
Or stream by filter is even removed completely, it can not possibly to make test become.

It is related to regularly replacing a large amount of filters.The above-mentioned type is potentially prone to other clamp systems, is replacing air draught
(for example, if filter is not properly oriented, washer is not complete for any mistake caused by during filter in system
Work, clamp system is without correctly closing etc.) dangerous substance may be caused to leak into ambient enviroment.In addition, to Mr. Yu
The HEPA filters of a little types, filter surfaces are very fragile, in some instances it may even be possible to be damaged because of slight touch.
The filter that Compulsory Feature inspection in some applications is mounted in filter housing due to the above reasons, is nothing
Leakage and meet filtration grade.This is swept by including being completed for the part of filter housing by scanning head by this
Probe is retouched, air is collected in the downstream of filter and is analyzed about undesirable substance.With air inlet and by air sample
This offer to analyzer scanning head close to filter surfaces the distance defined at move in a controlled manner, so as to
The sample in the very small region from filter is obtained when appropriate.If analyzer should can be sent out when concentration increases
It now reveals, then needs to detect very small region.Therefore, it is desirable to air stream will not be hindered to reach the case where popping one's head in from filter
Under, so that probe is mounted so as to as close to filter surfaces.
It has been developed that mobile to scan the different designs of the test probe of filter area.A kind of its test probe is long
The test probe of shape, the elongated test probe extend along the length or width of filter, and manual or motor-driven by some
Mechanism, such as cylinder, drive screw, move back and forth perpendicular to its longitudinal extension, to scan the area near filter surfaces
