Abstract

The utility model relates to an inflation tubular filter for water sample collection system, its structure appears for the round platform at both ends, it is middle for being full of the spherical filter material of polytetrafluoroethylene in the columniform casing, the net piece is sheltered from in the sealing -in respectively in two ports of casing, with with the filter material shutoff inside the casing, the diameter of the spherical filter material of the polytetrafluoroethylene that is full of in the casing unanimity of should trying one's best, the different spherical filter material of polytetrafluoroethylene of particle diameter and can pack into in the filter of difference, with the filtration needs that satisfy different quality of water. Connect the end that inserts of quick spigot -and -socket joint on a port of casing, connect the flaring end of quick spigot -and -socket joint on another port of casing, quick spigot -and -socket joint is used for the connection between the filter, perhaps is arranged in the butt joint with other devices of water sample collection system. The utility model discloses can filter muddy thing or suspended solid material in the water sample, and can not exert an influence to each component in the water, the fidelity of having improved the sample.

Description

For the expansion tube type filtrator of water sampling system

Technical field

The utility model relates to a kind of filtration unit, specifically a kind of expansion tube type filtrator for water sampling system.

Background technology

Along with the development of the modern industry, environmental pollution produces thereupon, and water pollution is also more and more taken seriously, in order to ensure the sustainable development of water resource, to the detection of water body with investigated into requisite work.In the process of analyzing and researching containing the water quality of volatile matter, oxygen sensitivity material of discharging pump line, collecting Hi-Fi water sample sample is the prerequisite truly reflecting sample characteristic, and this also just has higher requirement to water sampling system.

Existing water sampling system adopts mouth of pipe grafting or insert the mode sampled to carry out sampling operation, water sample pumps into sampling bottle through self-priming pump after taking out from pump line draining, also filtrator will be added when having during suspended solid material in the water muddiness intending discharging in sampling pump outlet or water, and existing filtrator is while filtering the muddy thing in water body or suspended solids, also the component to be detected in water body can be had an impact, thus reduce the fidelity of institute's water sampling.

Utility model content

The purpose of this utility model is just to provide a kind of expansion tube type filtrator for water sampling system, to solve existing metre filter containing the low problem of the fidelity that exists during environmental sensitivity material water sample.

The utility model is achieved in that a kind of expansion tube type filtrator for water sampling system, be truncated cone-shaped at two ends, middle be full of the spherical filtrate of teflon in columniform housing, be sealed with respectively in two ports of described housing and block mesh sheet, a port of described housing is connected to the socket end of Quick spigot-and-socket joint, another port of described housing is connected to the flared end of Quick spigot-and-socket joint.

When the water intending discharging in sampling pump outlet is muddy or have suspended solid material in water, by in this device access water sampling system, when the liquid level of water sample rises in housing, the velocity variations that liquid level rises is more stable, when water sample liquid level rises in the truncated cone-shaped housing of bottom, liquid level ascending velocity linearly reduces, to the joint portion of the cylindrical housings of centre after, the ascending velocity of liquid level reaches minimum value; After entering intermediate cylindrical housing, the speed that liquid level rises keeps inconvenience, and the speed that after arriving the truncated cone-shaped housing of upper end, liquid level rises linearly increases, and during to upper end outlet place, speed reaches maximal value.In the whole process that liquid level rises in housing, velocity variations is steady, sharply do not change, water sample in conical shell and contained environmental sensitivity material are in relative dynamic equilibrium state, less by disturbance, reduce the probability of the effusion of volatile matter in sample, the spherical filtrate of teflon can filter out muddy thing in water sample or suspended solid material, and can not each component in water body be had an impact, improve the fidelity of sample.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1, housing, 2, the spherical filtrate of teflon, 3, block mesh sheet, 4, insertion end, 5, flared end.

Embodiment

As shown in Figure 1, the utility model is full of the spherical filtrate 2 of teflon within the case 1, the upper/lower terminal of housing 1 is that truncated cone-shaped, centre are for cylindrical, be sealed with respectively in two ports of housing 1 and block mesh sheet 3, in order to the shutoff of spherical for teflon filtrate 2 is inner at housing 1, the diameter of the spherical filtrate 2 of the teflon be full of in housing 1 should be tried one's best unanimously, and the spherical filtrate 2 of the different teflon of particle diameter can be loaded in different filtrators, to meet the filtration needs of different quality.A port of housing 1 is connected to the insertion end 4 of Quick spigot-and-socket joint, another port of housing 1 is connected to the flared end 5 of Quick spigot-and-socket joint, the insertion end 4 of Quick spigot-and-socket joint and flared end 5 grafting coordinate, for the connection between filtrator, or for the docking of other devices in water sampling system.

Claims (1)

1. the expansion tube type filtrator for water sampling system, it is characterized in that, be truncated cone-shaped at two ends, middle be full of the spherical filtrate of teflon in columniform housing, be sealed with respectively in two ports of described housing and block mesh sheet, a port of described housing is connected to the socket end of Quick spigot-and-socket joint, another port of described housing is connected to the flared end of Quick spigot-and-socket joint.
