Abstract
The utility model provides a de-burring dust-fall collector. By adopting a split structure design, the collector comprises a dust gather cover, a funnel, a protective barrel, a sample box, a fixed support and a filter net, wherein the funnel and the dust gather cover are mutually connected with the protective barrel through threads, the filter net is used for holding up foreign matters and preventing from the mixture of foreign matters and dust-fall samples, the collector achieves the filtering of foreign matters in the natural settlement gathering process, increases the purity of samples, lowers the exposure amount of samples in the air flow, effectively inhibits 'secondary dust-raising ', enhances the dry-type collection efficiency, reduces the evaporation amount of water in the collector when in wet type collection to facilitate the wet type collection in drought region, and directly collects dust-fall samples in the independent sampling unit to be convenient for connecting samplesand lowering the work load. The collector has the advantages of high purity of collection of samples, high dust gathering efficiency, convenient sampling, broad application scope and durable service.The collector can be widely used in researches such as environment, ecology, wind-sand geomorphology and sand-protecting engineering.
Description
Technical field
The utility model relates to the collection equipment of atmospheric falling dust in the atmosphere quality monitoring.
Background technology
Existing depositing dust collector exists that the dry type collecting efficiency is low, arid biogeographic zone can't carry out problems such as wet type collection, sample contaminating impurity and sample procedure be loaded down with trivial details.Container nature collecting method is to utilize action of gravity to make depositing dust be deposited on a kind of collection method in the container, and it is the universal method that present depositing dust is gathered near the natural subsidence process of depositing dust.Dustfall jar is all purpose instrument of depositing dust observation, is widely used in the atmosphere environment supervision, and also be present emerging instrument---the important component part of depositing dust automatic collector.
According to the difference of dust collecting container internal fixation depositing dust medium, can be divided into dry method, wet method and 3 kinds of modes of glass bead method.Because these 3 kinds of modes suppress the ability difference of " secondary plays dirt ", so their collection efficiency is also different, and the dust catching efficiency of wet type is the highest, the glass bead formula secondly, dry type is minimum.According to domestic and international research, the dust catching efficiency of three kinds of collection modes has certain proportionate relationship (also claiming conversion factor K), but the zone is different, and the K value is also different.Therefore, have only each zone all to obtain the K value by the parallel observation of multimode, the depositing dust data between each zone just can be carried out science relatively.In addition, because evaporation potential is big, the wet type depositing dust is collected and can not be realized fully at arid biogeographic zone, and dry type is collected and had more operability.Therefore, existing dustfall jar has been unsuitable for the observation of arid biogeographic zone depositing dust to a certain extent, presses for a kind of novel depositing dust collector that improves dry type collection efficiency (suppress secondary and play dirt) or be convenient to the wet type collection of design.
Limited by housing structure, when shifting sample in the observation site, wind easily makes sample segment elegant, causes observing inaccurate.Therefore in actual use, all use clean dustfall jar to displace the dustfall jar of observing on the support, add a cover then, bring transfer sampling again behind the laboratory into.When the depositing dust observation station more for a long time, it is loaded down with trivial details that this method just seems.In addition, existing dustfall jar also has the following disadvantages: be difficult to realize selective collection.Birds droppings, plant residue, insect corpse etc. often are mingled in the depositing dust sample, are difficult to separate, and cause sample contamination, have reduced the accuracy of data; Sample cleaning difficulty.When dry type was collected, rainwater or dew bonded together depositing dust sample and cylinder body, and on-the-spot cleaning is difficulty relatively.
In addition, domestic dustfall jar material is common plastics, glass or pottery, and vulnerability is strong, and the sun is exposed to the sun, strong wind, gravel, hail, factor such as artificial cause dustfall jar to damage easily, acquisition sequence is interrupted or error increases.
At the problem that existing depositing dust collection equipment exists, the utility model designs a kind of removal of impurities depositing dust collector.This collector has dry type collection dust catching efficiency height, arid biogeographic zone can carry out wet type collection, convenient accurately, wide, the long-lived characteristics of usage range of sampling.
Summary of the invention
The utility model purpose is, a kind of removal of impurities depositing dust collector is provided, this collector adopts the split-type structural design, form by dust gathering arrester, funnel, protection bucket, sample box, fixed support and screen pack, this collector can carry out contaminant filter in the natural subsidence collection process, improve collected specimens and gather purity; Reduce the exposed amount of sample in air-flow, effectively suppress " secondary plays dirt ", improve dry type dust catching efficiency height; Wet type can reduce water evaporates in the collector when gathering, and wet type is collected also can carry out at arid biogeographic zone; The depositing dust sample directly is stored in the separate unit, makes sample collecting more convenient, reduces workload; Collector is durable in use, and is not fragile.
A kind of removal of impurities depositing dust collector described in the utility model, form by dust gathering arrester (1), funnel (2), protection bucket (3), sample box (4), fixed support (5) and screen pack (6), have the hole at protection bucket (3) inner bottom part, and at bottom placement fixed support (5), middle part at fixed support (5) embeds sample box (4), and funnel (2) interconnects with protection bucket (3) and dust gathering arrester (1) by the internal thread of upper and lower mouthful of sidewall.
At the fixedly 20-32 order screen pack suitable for reading (6) of funnel (2), the short neck of funnel (2) and sample box (4) socket.
Dust gathering arrester in the collector (1), funnel (2) and protection bucket (3) adopt Polyvinylchloride or glass-reinforced plastic material to make.
Screen pack in the collector (6) and fixed support (5) adopt stainless steel material to make.

Embodiment
Further describe and provide embodiment below in conjunction with accompanying drawing
A kind of removal of impurities depositing dust collector described in the utility model adopts the split-type structural design, is made up of dust gathering arrester (1), funnel (2), protection bucket (3), sample box (4), fixed support (5) and screen pack (6); Have aperture at protection bucket (a 3) inner bottom part, the abundant precipitation of when being used for a large amount of rainfall sample box (4) being overflowed is discharged outside the instrument; Protection bucket (3) bottom is provided with fixed support (5), sample box (4) is embedded the middle part of fixed support (5); Sample box (4) bottleneck has external thread, can add a cover and seal, and is used for collecting, holding the depositing dust sample.Funnel (2) interconnects with protection bucket (3) and dust gathering arrester (1) by the internal thread of upper and lower mouthful of sidewall, in fixedly 20-30 order screen pack (6), the short neck of funnel (2) and sample box (4) socket of the place suitable for reading of funnel (2).Dust gathering arrester (1), funnel (2) and protection bucket (3) adopt Polyvinylchloride or glass-reinforced plastic material to make, and screen pack (6) and fixed support (5) adopt stainless steel material to make.
