Abstract

The invention discloses an automatic membrane change device and method for air particulate matter samples. The device comprises an upper closing cavity, a lower closing cavity, a porous moving disk, atransmission device I, a transmission device II and a controller, wherein the upper closing cavity and the lower closing cavity are located in a dustproof box; the porous moving dick is located between the upper closing cavity and the lower closing cavity and is sued for bearing a filter membrane tray; the transmission device I drives the moving disk to move horizontally; the transmission deviceII drives the lower closing cavity to lift; the controller controls the transmission device I and the transmission device II to move; the upper closing cavity is connected with a cutter connection head at the top of the dustproof box; the lower closing cavity is connected with an air pump through a pipeline; a horizontal displacement sensor is arranged on the transmission device I; a vertical displacement sensor is arranged on the transmission device II; and the air pump, the horizontal displacement sensor and the vertical displacement sensor are electrically connected with the controller. Thedevice disclosed by the invention is capable of realizing the automatic change of a plurality of filter membranes so as to decrease the operation cost, and is reliable in operation.

Description

technical field [0001] The invention relates to an automatic membrane changing device and a membrane changing method, in particular to an automatic membrane changing device and a membrane changing method of an air particle sampler. Background technique [0002] The air particle sampler captures the total suspended particles and inhalable particles in the ambient atmosphere by the filter weighing method, and is used for the routine detection of aerosols. At present, the air particle sampler is mainly staffed on duty, and the filter membrane needs to be replaced manually on site. When continuous long-term sampling or multi-membrane interval sampling is required, it is necessary to regularly go to the sampling site to replace the filter membrane, which brings a lot of repetitive labor to the operator and greatly increases the labor intensity of the operator. For the sampling unit, the on-site duty also increases the input of personnel. [0003] If the filter membrane cannot b...
