Description

Dust collector

Technical field

The utility model relates to the fields such as environmental monitoring sample devices, is specifically related to a kind of dust collector.

Background technology

Dust (Dust) refers to that suspension is aerial solidparticulate, in live and work, dustbeing the natural enemy of human health, is the main cause of bringing out various diseases.

Be exposed to the laborer producing dust place for a long time, accumulation dust is caused pneumoconiosis by lung, and consequently two lobes of the lung of Pneumoconiosis Patients produce Progressive symmetric erythrokeratodermia, diffuse proliferation of fibrous tissue, develop into the function hindering breathing function and other organs gradually.The most common, the most serious class occupational illness of harm at our pneumoconiosis.

In environmental monitoring, often need to carry out sampling to the dust in environment and detect, dust detects and mainly comprises dust in air collection, dispersion degree detection, Concentration Testing etc., at present, dust collection mainly uses filtrate sampling folder to sample, but this filtrate sampling folder also exists following defect:

1, filtrate sampling folder is airtight not sternly, and from the seam crossing gas leakage of filtrate sampling folder during sampling, gas leakage just can not ensure accuracy and the repeatability of sampling;

2, in dust testing process, be often by air sample collection and preserve, then take back lab analysis, filtrate sampling is clipped in replacing and preservation process, need be higher to operator's technical requirement, and whole process operation gets up more loaded down with trivial details, workload is large, too increases the opportunities for contamination of sampling sample.

Utility model content

In order to overcome the deficiency of background technology, the utility model provides a kind of dust collector, mainly solve the problem of airtight tight, the acquisition operations of existing filtrate sampling folder and Sample storage inconvenience, this dust collector is simple and reasonable, filter membrane can be fixed well, connect closely, reliability is high, greatly can reduce the workload of operating personnel, and increase work efficiency, strengthen the convenience of dust sampling and the security of Sample storage, device can be reused, with low cost, simple to operate, be easy to promote.

The technical scheme that the utility model adopts is: a kind of dust collector, it comprises pedestal, packing ring, upper clamp ring, inner bushing ring, upper clamp ring, spiral cover, described pedestal is inwall is that threaded ring bodies is established in smooth curved surfaces and outside, described pedestal is connected with packing ring, lower clamping is placed with above described packing ring, described lower clamping is inwall is that threaded ring bodies is established in smooth curved surfaces and outside, inner bushing ring is placed with above described lower clamping, clamp ring is connected with above described lower clamping, described upper clamp ring is that threaded ring bodies is established in inner side, spiral cover is connected with above described pedestal, described pedestal comprises bottom base, top base, and described bottom base is inwall is that threaded ring bodies is established in smooth curved surfaces and outside, be provided with bottom base brace table above described bottom base, described bottom base brace table is positioned in the middle part of pedestal, be connected with top base above described bottom base, described top base is inwall is that threaded ring bodies is established in smooth curved surfaces and outside, and described pedestal is integral type structure, described packing ring is fixedly mounted in the middle part of pedestal, described inner bushing ring is both ends open truncated cone-shaped tubular structure, described spiral cover comprises screwed lid and air intake opening, and described screwed lid is that threaded ring bodies is established in inner side, and described air intake opening is both ends open, inwall is smooth curved surfaces truncated cone-shaped tubular structure.

The beneficial effects of the utility model are: owing to taking technique scheme, this dust collector is simple and reasonable, can fix filter membrane well, connects closely, reliability is high, greatly can reduce the workload of operating personnel, and increase work efficiency, strengthen the convenience of dust sampling and the security of Sample storage, device can be reused, with low cost, simple to operate, be easy to promote.
