Description
Technical field
The present invention relates to fluid sample to sample field, more particularly to a kind of turnover plate type methane-generating pit solidliquid mixture sampler.
Background technology
In hydrogeology, it is often necessary to detect the composition of underground water, such as iron in water, fluorine, zinc, copper, chromium, manganese, iodine,
The elements such as molybdenum, cobalt, these elements are that human body is necessary, extremely important to the eubolism of life.Many endemic diseases are exactly
Caused by people drink non-compliant water for a long time, as high-fluorine water cause den tal fluorosis, low iodine water cause goitre,
High arsenic water causes cutaneum carcinoma etc..At present, underground water acquisition method is in the port that liquid flows out or liquid cell using wide-mouth bottle
In directly gather, due in same liquid cell, the liquid component at different depth may be different, therefore, it is necessary to use wide-mouth
The bottle liquid at collection different depth, and being numbered for distinguishing by several times, finally detects the liquid after numbering, ability respectively again
The composition of the liquid at different depth is obtained, the gatherer process of this underground water acquisition mode is extremely complex, and collecting efficiency is relatively low.
To have special odor or it is poisonous, need waterproof, antipollution sample to realize sealing sampling, common fluid sample takes
Sample instrument can not be competent at, old sampling mode, usually rotate opened type probe tube storehouse, and it is poor sealing effectiveness to be present, easily intersects
The problems such as pollution, it is inconvenient to carry, and onsite application is restricted；Methane-generating pit smell is unpleasant, and suction for a long time may cause
Life.In summary, case above brings great difficulty to analysis work, on the one hand causes sample cross contamination, sealing effectiveness
Difference；On the other hand it is not portable and fixed, it is also safe the problem of.
By patent searching database, such as：Anti-pollution liquid sampler CN2888436Y, seal type liquid gas sample collector
