Abstract

The invention discloses a membrane sampling device capable of lifting to move. The membrane sampling device is characterized by comprising a framework, as well as a cutter joint, a seal ring, a filter membrane clamp, a filter membrane clamp fixed disk, a lifting air chamber and a lifting locking mechanism and an air cock which are arranged in the framework; the lifting locking mechanism is arranged on the lower part of the lifting air chamber. The filter membrane clamp can be put in or taken out conveniently and fast through the membrane sampling device capable of lifting to move, therefore, samples are simply and conveniently put in or taken out, a great deal of filter membrane taking and changing time can be saved, the working efficiency can be improved, and samples are not easily lost.

Description

technical field [0001] The invention relates to a film sampling device capable of lifting and moving, and belongs to the technical field of environmental monitoring. Background technique [0002] The filter-membrane particulate sampler currently used uses the filter membrane to capture the particulate matter, and realizes the hierarchical sampling of the sample by being equipped with different cutting heads. This type of sampler usually adopts a large-flow sampling method, which can obtain more particulate matter samples for analysis in a short time, so it is suitable for collecting atmospheric particulate matter samples. However, in the prior art, the sampler used to collect particulate matter samples is composed of a particulate matter cutter, a filter membrane, a flow meter and an air suction pump. It is fixed and sealed in the air path below the cutter. The disadvantage is that when loading or removing the blank filter membrane and the sample, the filter membrane holder...
