Description

Technical Field

[0001] The utility model belongs to the technical field of filter detection, and more specifically, particularly relates to a filtering and separation detection device. Background Art

[0002] High-efficiency filters have high filtration efficiency and are widely used in dust-free purification workshops such as optical electronics, biomedicine, etc. High-efficiency filters need to be strictly tested before leaving the factory. When testing high-efficiency filters, a filtration and separation detection device is required. The existing filtration and separation detection device is mainly composed of a fan, an aerosol generator, a particle counter and an air outlet platform. The high-efficiency filter is fixed on the air outlet platform, and the fan extracts gas and the atomized aerosol emitted by the aerosol generator and mixes them and blows them toward the high-efficiency filter. The particle counter scans the surface of the high-efficiency filter to detect and locate the leakage point.

[0003] Existing application number CN201720877030.X The utility model provides an air outlet platform for high-efficiency filter detection, which includes a frame, a gas delivery device installed on the frame, a gas detector, a dust generating device and a blower; the blower is used to transport the dust particles generated by the dust generating device to the air inlet side of the gas delivery device, and the gas detector is used to detect the gas on the air outlet side of the air outlet platform; the outlet of the gas delivery device is sealed and connected with an air outlet plate, and the air outlet plate is provided with a plurality of air outlet holes, and the air outlet holes are through holes arranged on the air outlet plate at intervals, and an air outlet control device for opening or closing the air outlet holes is installed in the air outlet holes. The air outlet platform for high-efficiency filter detection provided by the utility model has the advantages of adjustable air outlet volume and convenient and quick operation.

[0004] Based on the above, most of the existing filtration and separation detection devices clamp the high-efficiency filter through a clamp, but the clamp cannot make the high-efficiency filter close to the air outlet platform well, which easily causes a gap between the high-efficiency filter and the air outlet platform. The poor sealing causes errors in the test results, and dust and impurities easily clog the filter on the surface of the fan when the fan draws air. If it is not cleaned for a long time, the fan's exhaust efficiency will be reduced, affecting the adjustment of the rated air volume and causing errors in the test. Utility Model Content

The poor sealing makes the detection result erroneous, and dust and impurities easily clog the filter screen on the surface of the fan when the fan draws air. If it is not cleaned for a long time, the fan's exhaust efficiency is likely to decrease, affecting the adjustment of the rated air volume and causing errors in the test.
