Automatic PM2.5 sampler film replacing device and use method thereof

Abstract

The invention discloses an automatic PM2.5 sampler film replacing device and a use method thereof. The automatic PM2.5 sampler film replacing device comprises a linear module, a pneumatic claw, a proximity sensor, a cutter connecting base, a pressing cylinder, a guide groove top cover, a guide groove base, a filtering film storage bucket, a sealing cylinder, a sealing connector, a filtering film loading bucket and a connecting base, wherein the linear module is arranged horizontally; the bottom surface of the linear module is connected with the connecting base through bolts; the pneumatic claw is mounted on a sliding component of the linear module through bolts; the linear module is capable of driving the pneumatic claw to move in the horizontal direction stably and precisely; the guide groove base is horizontally mounted on the connecting base through bolts; the filtering film loading bucket and the filtering film storage bucket are mounted below the guide groove base through L-shaped grooves; the sealing cylinder is fixed below the guide groove base through bolts; the sealing connector is in threaded connection with the sealing cylinder. Due to adoption of an electric and pneumatic mode, the automatic PM2.5 sampler film replacing device is reasonable in structure, convenient to mount and dismount and good in stability.

Description

technical field [0001] The invention relates to the field of environmental protection instruments, in particular to a PM 2.5 An automatic membrane changing device for a sampler and a method for using the same. Background technique [0002] Currently, air quality monitoring is used to collect PM 2.5 Most of the instruments are single-membrane samplers. Compared with automatic membrane-changing samplers, the operating frequency is more frequent, and the manual operation time is longer. At present, most of the membrane-changing mechanisms of automatic membrane-changing samplers use pure pneumatic methods, which have low precision and poor stability, and are greatly affected by environmental factors. Contents of the invention [0003] The invention provides a PM 2.5 The automatic membrane changing device of the sampler and its use method adopt electric combined with pneumatic mode, which has reasonable structure, convenient disassembly and strong stability, and solves the p...
