Automatic liquid separation sampler
Technical field
The present invention relates to a kind of automatic liquid separation sampler for liquid is sampled.
Background technology
After the fields such as scientific research and development often need to be to leachate, resin adsorption liquid, resolve after the certain volume in liquid interval such as liquid get a certain amount of sample and chemically examine, to analyze the composition of liquid in different time sections.When the liquid of needs samplings is slow at flow velocity, flow is little in the situation that, the work period of sampling may reach several days or some months, although workload is very little, needs special messenger to be responsible for, and takies human resources.
Summary of the invention
The object of the invention is: a kind of automatic liquid separation sampler without special messenger's timing sampling is provided.
Technical scheme of the present invention is: a kind of automatic liquid separation sampler, the vessel that comprises vertical setting, this vessel from top to bottom interval be provided with some chokes, each choke is separated into by vessel inner chamber minute sap cavity that some volumes equate, choke between sap cavity passed through in adjacent two minutes is communicated with, at the separatory top of chamber that is positioned at topmost, be provided with inlet, on the sidewall of each minute sap cavity, be separately installed with drain pipe, on each drain pipe, be separately installed with sample cock, in each minute sap cavity, be also respectively equipped with hollow float, the diameter of each hollow float is greater than the internal diameter of the reducing of corresponding separatory top of chamber or sample tap, at each minute, in sap cavity bottom interior wall, be fixed with respectively the ball float baffle plate that departs from reducing position.
Also comprise sampling cup, described vessel is fixedly placed in this sampling cup.
Described reducing internal diameter equates with inlet internal diameter, the equal diameters of described each hollow float.
Described drain pipe is to install the U trap being fixed on corresponding minute sap cavity sidewall, and each siphonal entrance stretches into the bottom of corresponding minute sap cavity, and described sample cock is installed on each siphonal endpiece.
Automatic liquid separation sampler of the present invention utilizes choke that container is separated into some sap cavities that independently divide, during use, the liquor sample flowing out from sample tap flows into vessel and fills with successively from bottom to up each minute sap cavity from the inlet at top, within each minute, sap cavity is when filling with, thereby the choke sealing that the hollow float arranging in it can automatically float adjacent minute is communicated with between sap cavity, make the liquor sample in each minute sap cavity mutually isolated, the drain pipe that can connect by each minute sap cavity after sample collection takes out respectively each sample, it has effectively avoided occurring to mix and impact analysis result between liquor sample, by this automatic liquid separation sampler, within a work period, once can collect all samples, sample collection process is without additionaling power, without special messenger, be responsible for, efficiently solve the defect that prior art exists.
Accompanying drawing explanation
Fig. 1 is the structural representation of automatic liquid separation sampler of the present invention.
Embodiment
The specific embodiment of automatic liquid separation sampler of the present invention as shown in Figure 1, it comprises a vertical vessel 1 arranging, on this vessel 1, interval is provided with the choke 2 that some internal diameters are equal, each choke 2 is separated into by vessel 1 minute sap cavity 3 that some volumes are identical from top to bottom, within adjacent two minutes, sap cavity 3 is communicated with by corresponding choke 2, the top of dividing sap cavity 3 in the superiors is provided with inlet 7, and the internal diameter of this inlet 7 equates with the internal diameter of choke 2.At each minute, in sap cavity 3, be respectively equipped with hollow float 4, the diameter of this hollow float 4 is greater than the internal diameter of choke 2, when sampling, each hollow float 4 falls under gravity to the bottom of corresponding minute sap cavity 3, the position of meanwhile, departing from choke 2 in the bottom interior wall of each minute sap cavity 3 is vertically fixed with respectively ball float baffle plate 5.Within each minute, sap cavity 3 is also connected with for taking out the drain pipe of liquor sample, and in the present embodiment, this drain pipe adopts and installs the U trap 8 being fixed on corresponding minute sap cavity 3 sidewalls, at the endpiece of each U trap 8, is respectively equipped with sample cock 9.In the present embodiment, in this vessel 1, be provided with successively three chokes 2, thereby will in vessel 1, be divided into four minutes sap cavities 3.
During use, this automatic liquid separation sampler is positioned over to sample tap below, the liquor sample that sample tap flows out flows in vessel 1 slowly by inlet 7, liquor sample is filled with each minute sap cavity 3 from bottom to up successively, within each minute, sap cavity 3 is all closed with its upper strata and is divided the choke 2 being communicated with between sap cavity 3 by the hollow float 4 of automatic floating when filling with, to avoid mixing occurring and impact analysis result between liquor sample, when a minute sap cavity 3 for the superiors is filled with, by hollow float 4, close inlet 7, complete a liquor sample collection work in the work period.After liquor sample has been collected, according to order from top to bottom, open respectively the sample cock 9 on the U trap 8 that each minute sap cavity 3 connect, take out successively each minute liquor sample in sap cavity 3.
In addition, for avoiding not closing in time sample tap after sample collection, cause liquor sample to overflow, automatic liquid separation sampler of the present invention is also provided with the sampling cup 6 that a diameter is greater than vessel, by vertical being fixed in this sampling cup 6 of vessel 1, can utilize on the one hand sampling cup to collect the liquid overflowing, also be convenient on the other hand using and depositing of this sampler.
Adopt automatic liquid separation sampler of the present invention can within a work period, complete the collection work of all liq sample by controlling the flow velocity of the liquor sample of sample tap, in sample collection process, without additionaling power, responsible without special messenger, only need after a work period, fetch this automatic liquid separation sampler.
