Abstract
The utility model discloses a pretreatment device of water sample detection algae, which comprises a case, a pipe-shaped sample inlet, a pipe-shaped sample outlet and a primary filter, wherein the pipe-shaped sample inlet is arranged at one end of the case and is connected with an external sample inlet pipeline, the pipe-shaped sample outlet is arranged at the other end of the case, the diameter of the pipe-shaped sample inlet and the diameter of the pipe-shaped sample outlet are smaller than the diameter of the case, a secondary filtering tube with an opening arranged at one side is arranged in a hollow part inside the case, the opening end of the secondary filtering tube is connected with the pipe-shaped sample inlet and is matched with the pipe-shaped sample inlet, the other end of the secondary filtering tube is a semi-spherical bottom end, the primary filter is arranged in the pipe-shaped inlet and is matched with the inner diameter of the pipe-shaped sample inlet, and filtering screen holes of the primary filter are larger than filtering screen holes of the secondary filtering tube. The utility model can provide qualified alga detection water samples with low impurity content for the water sample detection.
Description
Technical field
The utility model relates to a kind of device that detects in the algae, especially relate to a kind of in the water sample detection algae to water sample in the pretreatment unit of the impurity water sample detection algae of filtering.
Background technology
Algae in the water sample is detected, require to contain too many impurity in the water sample to be measured, otherwise can have influence on the accuracy of detection, water sample from the collection of lake water, usually contain other abiotic impurity and organism and biological residual body, but general now is with filter screen the bigger contaminant filter in the water sample of gathering to be fallen, and granule impurity is difficult to remove and wherein still have greatly.
Summary of the invention
At problem set forth above, the utility model purpose is to provide a kind of pretreatment unit that can effectively filter the water sample detection algae of various impurity in the water sample.
The utility model is realized by following technical measures, the pretreatment unit of a kind of water sample detection algae, comprise shell, be arranged on the tubular injection port that shell one end connects extraneous sample channel, be arranged on the tubular outlet of the shell other end, the diameter of this tubular injection port and tubular outlet is less than the diameter of shell, hollow is provided with the cascade filtration tube of an end opening in the described shell, the openend of this cascade filtration tube connects tubular injection port and cooperates with tubular injection port, the cascade filtration tube other end is the hemispherical bottom, the grade one filter that cooperates with tubular injection port internal diameter in the described tubular injection port, the opening of sieve of this grade one filter is greater than the opening of sieve of cascade filtration tube.
The preferred stainless steel casing of above-mentioned shell, cascade filtration tube preferably are spliced by 80 order stainless steel mesh, and the preferred 30 order stainless steel mesh of grade one filter preferably have the threaded engagement of anti-siphonage, cleaning for convenience detach in grade one filter and the injection port.
The utility model carries out coarse filtration by the one-level screen pack to water sample, hold back minute impurities after the coarse filtration by the cascade filtration tube again, the filtered water that will contain little living algae is by the temporary of urceolus and evenly enter the after-treatment device that is connected with tubular outlet after the mixing.The utility model can detect water sample for water sample detection provides the few qualified algae of impurity content.
Description of drawings
Fig. 1 is the utility model cross-sectional view.
The specific embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further detail.
The pretreatment unit of water sample detection algae, as shown in Figure 1, the stainless steel casing 4 of installation, the steel plate bending thick by 1mm forms hollow circuit cylinder, outer surface process spray treatment, the inner surface sanding and polishing, seam crossing falls into smooth surface, makes things convenient for the turnover of water sample; Front end is tubular injection port 1, is fixed on the stainless steel casing 4 with holding screw, can connect sample channel; Screw thread is connected with grade one filter 2 in the porch of tubular injection port 1, and grade one filter 2 has anti-siphonage only to inner rotary, also is easy to disassembly, cleaning, and grade one filter 2 is 30 eye mesh screens of stainless steel; Cascade filtration tube 3 is installed in the inside of stainless steel casing 4, and material is a stainless steel, and with the splicing of 80 eye mesh screens, going to the bottom is the hemispherical cecum, is fastened with tubular outlet 5 at the rear of stainless steel casing 4 with screw.
Water sample can be outwarded winding one-level screen pack 2 behind double-filtration, and washes cascade filtration tube 3 with the shower water of cleaning, and water sample behind double-filtration and cleaning shower water flow out from tubular outlet 5; Will be from the water sample of tubular outlet 5 outflows, import a spheroid, filtered water and cleaning shower water mix in spheroid, after setting sampling amount, discharge the redundance sample, make sample volume only account for spheroid 1/3rd to 1/2nd between, seal the gateway then, be communicated with motor, make spheroid container fast rotational, frequency is set, change direction of rotation, can make alga cells such as blue-green algae cell strike the ball wall repeatedly, arrive setting-up time after, open outlet, give checkout gear with the sample that obtains and detect.
More than be that the structure of the pretreatment unit of the utility model water sample detection algae is set forth; be used for helping to understand the utility model; but embodiment of the present utility model is not restricted to the described embodiments; anyly do not deviate from the change done under the utility model principle, modification, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
