Efficient detection device for filter

Abstract

The invention discloses an efficient detection device for a filter, which comprises a working table, and supporting legs distributed at four corners of the working table are hinged to the lower end surface of the working table. A sliding base capable of sliding back and forth along the Y axis is arranged on the upper end face of the workbench, at least one sliding rod capable of sliding back and forth along the X axis is arranged on the sliding base, the end of each sliding rod is detachably connected with a telescopic rod capable of stretching out and drawing back along the Z axis, and the telescopic heights of the telescopic rods located on the different sliding rods are different. A clamping frame capable of swinging up and down along the telescopic rod is arranged at the upper end of the telescopic rod, the clamping frame can clamp a scanning head used for collecting gas, and the scanning head is connected with a host of an aerosol photometer located outside through a pipeline. An arm is replaced, a test position of the filter is more accurately entered, the test angle and speed are convenient and controllable, and the test precision and the test efficiency of the filter are improved.

Description

technical field [0001] The invention relates to the technical field of air detection, in particular to a high-efficiency detection device for filters. Background technique [0002] In production and life, filters are used more and more widely, especially in places with high environmental requirements such as biological safety cabinets, ultra-clean workbenches and clean workshops, filters are essential. When testing the filtration efficiency of the filter, an aerosol photometer is often required to test the filtration efficiency and leakage of the filter. At present, a hand-held leak detector is connected to the air inlet of the main engine of the aerosol photometer, and the hand-held leak detector is close to the filter to scan the filter. The end of the hand-held leak detector is provided with a funnel-shaped scanning head, and a fan is provided in the host of the aerosol photometer, and the fan will generate negative pressure at the scanning head of the hand-held leak det...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing aerosol photometer is in use, the scanning head of the aerosol photometer is generally held by the experimenter, and the high-efficiency filter is often installed at the high end of the safety cabinet, ultra-clean workbench and clean workshop, which is extremely difficult to detect. inconvenient

Moreover, continuous holding and lifting of the scanning head by human hands is prone to fatigue, the measurement position and measurement speed are difficult to control, and the measurement error is large, which cannot meet the precise test requirements.
