The set-up mode set is identical.When funnel 2 shift position of fixed plate, it is only necessary to movable fixing piece 17 is taken out, it then again will limit
Position block 16 and suitable first limit hole, 18 fixation can play position-limiting action.It should be noted that movable fixing piece 17 is spiral shell
Bolt.
Multiple sizes of through-hole 3 is offered in funnel fixed plate 2, is offered on bottom plate multiple with 3 position phase of through-hole
Corresponding container placing groove 4 offers drainage hole 5 in each container placing groove 4, is respectively connected with drain on each drainage hole 5
Pipe 6.
In the filter operation of environmental protection analysis, the different filter tunnel of all size is often used, it is therefore desirable to
Prepare various funnel retainer plates of different specifications and sizes respectively to fix the funnel of different size, and need when retainer plate use
It installs, is finished and needs to dismantle, it is comparatively laborious；In addition, if when various samples are filtered simultaneously, it is also necessary to prepare multiple leakages
Rack struggle against to operate, land occupation is big, inconvenient.The utility model offers multiple sizes of in funnel fixed plate 2
Through-hole 3 is used to place the funnel of various different sizes, practical and convenient, saves land occupation.
Container placing groove 4 is used to place beaker or three-necked flask, to accept the liquid flowed down in filter tunnel；This is practical new
Container placing groove 4 is arranged to place liquid container in type, and the position of container is fixed, multiple groups is avoided mutually to collide when operation,
Keep container position mobile, thus leakage.In addition, offering drainage hole 5 in each container placing groove 4, it is arranged on each drainage hole 5
There is drain pipe 6.When the liquid in filter tunnel splashes out beaker or three-necked flask accidentally, the liquid of spillage can be put by container
The drainage hole 5 opened up in slot 4 is set, is discharged via drain pipe 6, then by special container reception, so as to avoid the liquid splashed out
Body pollution work top influences operator's use.
Filter tunnel is plugged in through-hole 3, and filter tunnel includes bucket body and the lower liquid pipe being connected to bucket body bottom end 7, lower liquid
Liquid pass hole is offered on pipe 7, and two logical pistons 8 are plugged in liquid pass hole.In the utility model, the structure of filter tunnel and liquid separation leakage
It struggles against essentially identical, liquid separation can be played the role of, extracting operation can be carried out.
Bucket body includes exocoel 9 and inner cavity 10, and exocoel 9 is coaxially arranged with inner cavity 10, and between having between exocoel 9 and inner cavity 10
Gap, the top and bottom end of exocoel 9 are fixed on the outer wall of inner cavity 10, and the lower end of exocoel 9 offers exocoel water inlet pipe 11, upper end

Bucket body is arranged to double-layer structure by the utility model, and heat is injected in the gap between exocoel 9 and inner cavity 10
Water or cold water keep the temperature of filtering liquid in bucket body.When temperature is lower in winter, some subzero organic matters are easy
It condenses into solid to be retained by the filter screen in funnel, so that the accuracy of water-quality test result is influenced, at this time toward exocoel 9 and inner cavity
In gap between 10 inject hot water, liquid in funnel 7 is heated, make its temperature be maintained at organic matter freezing point it
On, prevent its condensation；When summer temperature is higher, volatile organic solvent is readily volatilized in filtering liquid, to influence water
The accuracy of matter test result injects cold water in the gap between exocoel 9 and inner cavity 10 at this time, carries out to liquid in funnel 7
Refrigeration, prevents its volatilization.
Bucket body upper end is sequentially arranged at intervals with the first strainer 14 and the second strainer 15, and the hole of the first strainer 14 from top to bottom
Diameter is 80-100 microns, and the aperture of the second strainer 15 is 1-10 microns.First strainer 14 and the second strainer 15 can be in water bodys
Impurity be filtered retention, and the utility model is arranged two layers of strainer and is segmented retention, can either improve filter efficiency, and can
Avoid filter net jam.When if necessary to measure suspension content in fluid sample, filtering finishes and filter tunnel can be placed in perseverance
Warm drying box constant weight, by calculate filter tunnel it is dry before and it is dry after of poor quality calculate suspended matter quality.
When needing while measuring suspended matter in fluid sample, oil content and median particle size, can grasp in accordance with the following steps
Make: filter tunnel is placed in through-hole 3, and passes through the slidable adjustment filter tunnel of first sliding groove 1 and second sliding slot to suitable height
Degree, then adds waste water into bucket body, and liquid level in bucket body is made to be lower than the second strainer 15, the first strainer 14 and the second filter
Net 15 is filtered the suspended matter in waste water, and the water-oil separating in bucket body toward filtrate, collects the oil isolated after filtering,
It is measured with spectrophotometer, then calculates oil content, filter tunnel is then rinsed with petroleum ether, dry with constant temperature after flushing
Dry case constant weight calculates suspension content, and scrapes the solid matter on the first strainer 14 and carry out median particle size measurement.
In the utility model, disclosed above is only specific embodiment of the utility model, and still, the utility model is implemented
Example is not limited to this, and the changes that any person skilled in the art can think of should all fall into the protection scope of the utility model.
