Problems solved by technology

However, the traditional sampling device can only collect one sample at a time. When multiple samples need to be collected, it needs to stop halfway and replace the single-particle filter membrane in the sampling collector several times. The replacement of the single-particle filter membrane needs to be done indoors and is ti

Example Embodiment

[0031] Example 1

[0032] A semi-automatic continuous single particle sampler, the structure is as figure 1 As shown, it includes a housing 11 with a support column inside, an air inlet pipe 5, an air pump, a power supply, a flow meter 8 and an air outlet pipe 6; the bottom of the housing 11 is fixed with a base 10, the base 10 is hollow, the air pump and the power supply Set in the base 10, the air pump is driven by a power source. Preferably, the power source is a AA battery. The base 10 is made of metal material, the indicator light 9 of the air pump is arranged on the upper part of the base 10, and a sampling head is arranged in the housing 11. The sampling head includes a funnel-shaped accelerating cavity 4, a sampling collector 1 and an air flow outlet device 12. The upper end of the air-shaped acceleration chamber 4 is in sealed connection with the air inlet pipe 5, the sampling collector 1 is connected and arranged between the funnel-shaped acceleration chamber 4 and the ...

Abstract

The invention relates to a semi-automatic continuous single particle sampling device, and belongs to the technical fields of atmospheric environmental science and environmental monitoring. The device comprises a shell, an air intake pipe, and an air pump communicated with an air exhaust pipe. A funnel-shaped accelerating cavity, sampling collectors and an air flow export device are arranged inside the shell. The upper end of the funnel-shaped accelerating cavity forms a sealing connection with the air intake pipe. The lower end of the air flow export device forms a sealing connection with theair exhaust pipe. The number of the sampling collectors is multiple, and the sampling collectors are uniformly arranged on a turntable in an annular manner. The turntable rotates by adopting a support column as a center axis, such that the sampling collectors distributed on the turntable are alternately communicated and arranged on the positions between the funnel-shaped accelerating cavity and the air flow export device. With the present invention, a plurality of different samples can be continuously collected, the replace of the sampling film is not required in the sampling process, such that the continuous sampling can be performed conveniently, or the sampling at the selected time period can be performed conveniently, and the device is applicable for a plurality of sampling situations.

Description

technical field [0001] The invention relates to an atmospheric sampling device, in particular to a sampler capable of semi-automatic continuous sampling operation, belonging to the technical fields of atmospheric environmental science and environmental monitoring. Background technique [0002] At present, the commonly used atmospheric single particle sampler system includes three parts: sampling head, flow meter and suction pump. The air pump draws air into the collector sampling head, which then captures the aerosols in the airflow on the filter membrane. However, the traditional sampling device can only collect one sample at a time. When multiple samples need to be collected, it needs to stop halfway and replace the single-particle filter membrane in the sampling collector several times. The replacement of the single-particle filter membrane needs to be done indoors and is time-consuming. Longer, the existing single particle sampler cannot perform continuous sampling, esp...
