Embodiment

[0040] refer to figure 1 , 2 , 3. This embodiment provides a turntable particle sampler with automatic membrane change, including a base 1, a feeding and storage membrane cylinder 2, a feeding mechanism 3, a feeding and storage membrane cylinder 4, a sampling head 5, and a photoelectric switch 6 , fixed seat 7, turntable 8, turntable rotation mechanism 9, described fixed seat 7 is fixed on the base 1, and described upper material storage film cylinder 2, unloading material storage film cylinder 4, sampling head 5 are fixed on the fixed seat 7, The turntable 8 is arranged in the fixed seat 7, and is connected with the turntable rotation mechanism 9 fixed below the base 1, the feeding mechanism 3 is fixed below the base 1, and the photoelectric switch 6 is used to determine whether the turntable 8 rotates in place. Membrane holders 10 are arranged sequentially in the film storage tube 4, and fall onto the turntable 8 by gravity. The turntable rotation mechanism 9 drives the tur...

Abstract

The invention provides a rotating disc type particulate matter sampler capable of automatically changing a film. The sampler comprises a base, a feeding film storage barrel, a feeding mechanism, a discharging film storage barrel, a filter film clamp, a sampling head and a photoelectric switch, wherein the feeding mechanism is located below the base, a fixing seat, a rotating disc and a rotating disc rotating mechanism are further included, the fixing seat is fixed on the base, the feeding film storage barrel, the discharging film storage barrel and the sampling head are fixed on the fixing seat, the rotating disc is arranged in the fixing seat and is connected with the rotating disc rotating mechanism fixed below the base, and the photoelectric switch is used for determining whether the rotating disc rotates in place or not. The sampler is advantaged in that the sampler is not provided with a complex transmission mechanism, is simple in structure and convenient to disassemble, assembleand maintain, reduces a linear module type vertical transmission mechanism, saves more space, greatly reduces the size of the whole machine, reduces one output power source and saves the cost as a filter film clamp in a discharging filter film cylinder falls down under the action of gravity.

Description

technical field [0001] The invention belongs to the technical field of small-flow particle samplers, and in particular relates to a rotary disk type particle sampler with automatic membrane change. Background technique [0002] The air particle sampler refers to the capture of total suspended particles and inhalable particles in the ambient atmosphere by the filter membrane weighing method for routine detection of aerosols. When changing the membrane in the general air particle sampler, first install the filter membrane on the filter membrane holder, and then install it in the filter membrane hole where the filter membrane holder can be placed, and replace it regularly to achieve sampling. This kind of particle sampler needs to continuously send new filter membranes for sampling, and at the same time send away and collect the filter membranes that have been sampled. The whole process of manual operation is time-consuming, laborious and inefficient. At present, some companie...
