An automatic membrane-changing air particle sampler

Abstract

The invention discloses an air particulate matter sampler capable of automatically changing a membrane. The air particulate matter sampler comprises a shell, a filter membrane storage mechanism, a lifting clamping rotation mechanism, a detection mechanism and a control device, wherein the filter membrane storage mechanism, the lifting clamping rotation mechanism, the detection mechanism and the control device are arranged inside the shell; the filter membrane storage mechanism comprises a to-be-detected filter membrane base and a detected filter membrane base which are arranged on an inner plate of the shell; the lifting clamping rotation mechanism comprises a lifting gear, a clamping device and a rotating device; the lifting gear is arranged on the inner plate of the shell; the clamping device and the rotating device are arranged on the lifting gear; the control device is connected to the detection mechanism and the lifting clamping rotation mechanism. By adopting the air particulate matter sampler, artificial membrane exchange is replaced by mechanical movement through multi-freedom motion of a mechanical structure, the long-term sampling requirements are met, and the labor intensity of a worker is greatly reduced, each filter membrane is automatically sampled by the system, the air particulate matter sampler is free of manual intervention, a user can know the working state of the machine in real time by remote control and monitoring, short message inquiring and notifying functions, an unattended operation is really achieved, and the air particulate matter sampler is reasonable in design, compact in structure, light in weight, good in portability and applicable to outdoor work.

Description

technical field [0001] The invention relates to an air particle sampler, in particular to an air particle sampler with automatic membrane replacement. 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 will bring a lot of repetitive labor to the operator and greatly increase the operation. The labor intensity of personnel, for the sampling unit, on-site duty also increases the input of personnel; therefore, an intelligent air particle sampler that can perform regular sampling or interval sampling, automatic membrane change, remote control, and unattended is needed. But there is no report on t...

Problems solved by technology

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 will bring a lot of repetitive labor to the operator and greatly increase the operation time. The labor intensity of personnel, for the sampling unit, on-site duty also increases the input of personnel; therefore, an intelligent air particle sampler that can perform regular sampling or interval sampling, automatic membrane change, remote control, and unattended is needed. But there are no reports on the products and technologies of this type of air particle sampler in the prior art
