Description
Technical field
The utility model belongs to biological sample screening washer technical field, is specifically related to a kind of zooplankton sample screening washer.
Background technology
In water body environment monitoring, be an important content to the monitoring of the value volume and range of product of zooplankton.
The screening of traditional zooplankton sample is filtered water body example by funnel and bolting silk, carries out monitoring results under being then placed on microscope by tweezers foreign bodies.
This mode due to funnel lower opening too small, unit time inner fluid throughput is limited, for the water body example of some larger scale of constructions, needs longer filtration time, also exist overflow risk; Meanwhile, if there is the water body example that the solid impurities such as mud exist, impurity will be deposited on the bottom of funnel together with zooplankton, adds a large amount of screening time; Moreover, because the material of bolting silk mostly is nylon, there is larger elasticity, be attached on inner wall of hopper not easily docilely, be unfavorable for the screening of sample.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of zooplankton sample screening washer, has larger filtration area, convenient disassembly, bolting silk surfacing, improves the efficiency of sample screening.
Concrete scheme of the present utility model is:
Zooplankton sample screening washer, it is characterized in that this sample screening washer comprises a cylinder and a base, bolting silk is provided with between base and cylinder, described base comprises an annulus corresponding with cylinder and a sealing ring connected with annulus, the periphery of annulus or the inwall of sealing ring are provided with deck, a connection section turned up is contained in the bottom of described cylinder, and this connection section is provided with the bayonet socket corresponding with deck.
By said apparatus, filtration area increases greatly, only needs rotating base just can by disengaging complete for bolting silk, and screening efficiency improves greatly.
Accompanying drawing explanation
Fig. 1 is the utility model sample screening washer structural representation.
Fig. 2 is the utility model sample screening washer understructure schematic diagram.
Fig. 3 is the structural representation of the utility model sample screening washer cylinder.
Fig. 4 is the inclined filter screen structural representation of embodiment.
Embodiment
As Figure 1-3, zooplankton screening washer comprises a cylinder 1 and a base 2, bolting silk 3 is provided with between base 2 and cylinder 1, described base 2 comprises an annulus 4 corresponding with cylinder 1 and a sealing ring 5 connected with annulus 4, the periphery of annulus 4 or the inwall of sealing ring 5 are provided with deck 6, a connection section turned up 7 is contained in the bottom of described cylinder 1, and this connection section 7 is provided with the bayonet socket 8 corresponding with deck.
In addition, in order to impurity screening is convenient, two-layer or bed filtration can be established, namely the larger filtering net in an aperture is set on cylinder 1, carries out bolting silk screening again by after impurity initial filter.
This filtering net can be the inclined filter screen that mesh diameter increases gradually, once have thinner silt exist can filter by upper strata filter opening.
It should be pointed out that the utility model is not only confined to above-described embodiment, every technical scheme based on the present utility model thinking, all should think and fall into protection domain of the present utility model.
