Description
Technical field
The present invention relates to a kind of The pretreatment, especially a kind of pre-treating samples in moveable-type soil detection and device.
Background technology
In recent years, because the population sharp increase, industrial fast development, solid waste is constantly stacked and is toppled over to soil surface, and harmful waste water constantly permeates in soil, and harmful gas in the atmosphere and floating dust also constantly drop in the soil with rainwater, have caused soil pollution.Soil pollution directly influences the 26S Proteasome Structure and Function of soil ecosystem, will ecological safety and people's health be constituted a threat at last.
Soil pollution pollutes to go wrong from generation and can lag behind the long period usually, and therefore, the soil pollution problem is much accounted of not too easily.The control soil pollution generally is with " putting prevention first ", and this just need pollute ambient soil and carry out assessment surveys, is subjected to the great attention of countries in the world environmental administration.
Along with development of technology, small-sized portable soil analytical instrument has appearred on the market, and the type instrumentation is simple, and is easy to carry.But humidity has remarkable influence to measurement, and humidity is big more, and is big more to the influence of determinand characteristic spectral line and scattered ray; In addition, the particle of measuring samples unevenness too big and particle can produce granularity effect and inhomogeneous broadening effect, thereby the accuracy of measuring is exerted an influence.
If will reduce measuring error, then need carry out before soil detects pedotheque being carried out pre-service.Generally be earlier pedotheque to be carried out dried to reduce in the sample moisture to the influence of measurement result, grind then and Screening Treatment, grinding makes the particle of sample become less, can guarantee that sample particle is even and sieve, the soil powder that filters out different-grain diameter simultaneously is to satisfy different analysis requirements.
Existing portable soil analyser generally is equipped with the soil treatment accessory bag, for realizing the pre-service to pedotheque, must be equipped with the sample drying device in the accessory bag, grind device and screening device etc.Do the preprocessing process that can realize before soil detects like this,, but also have following problem with elimination humidity, granularity and unevenness effect:
1, annex many and scattered, carry inconvenience.
Be equipped with dry device in the soil treatment accessory bag, grind device and screening device, annex is many, and more scattered, and it is bigger to take up space, and carries inconvenience; The more meeting of annex simultaneously increases the weight of portable soil detecting instrument, has increased field operation institute on-load amount.
2, troublesome poeration.
Because dry device, grinding device and screening device are separate, make and grind again in the process of screening from drying to, pedotheque will be transferred to the grinding device from dry device successively and transfer on the screening device again, make manually-operated cumbersome, prolong the pretreated time of pedotheque, reduced detection efficiency.
3, increased the contaminated chance of pedotheque.
The transfer of pedotheque between different components makes the pollution source of pedotheque contact more, increased the contaminated chance of pedotheque, brings error for the detection of pedotheque.
4, cleaning trouble.
In order to eliminate last time pre-service to back time pretreated influence, reduce the mutual pollution between the sample, before each pre-service, device to be cleaned.Because device is more, clean inconvenient.Simultaneously, each device is all cleaned, also can waste a lot of detection times, make the detection efficiency of pedotheque lower.
