Abstract
The utility model discloses a funnel type glass sand core filter comprising a tapered funnel, a straight pipe and a tapered pipe which are connected with one another from top to bottom, wherein the bottom of the straight pipe is provided with an acid and alkali resistant glass sand core, and resin is filled in the straight pipe and the upper part of the glass sand core. The glass sand core filter can be used for measuring nitrate nitrogen in a water sample, and completely eliminate the interference of organic matters in the water sample to the measurement, thus greatly simplifying the analysis process of the nitrate nitrogen in the water sample, and improving analysis speed and data reliability.
Description
Technical field
The utility model relates to a kind of chemical apparatuses, mainly is meant a kind of glass sand core filter.
Background technology
At water sample NO
3 -In-N the determination experiment, must remove the organic matter in the water sample.In the existing experiment, be used in combination, tear open and change complicated with vessel such as pallet, funnel, filter paper, Sheng sample bottles, and some oarse-grained impurity of filtration that can only be simple, be difficult to reach technical specification.
The utility model content
The technical problems to be solved in the utility model is to overcome the prior art defective, and a kind of funnel-form glass sand core filter is provided.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
Funnel type glass sand core filter comprises conical hopper, straight tube, conical pipe, and the three connects from top to bottom, and the bottom position of described straight tube is provided with the glass core, and described straight tube is interior, glass core top is filled with resin.
Further be improved to, described resin is large aperture resinene CAD-40 type or XAD-2 type resin.
Advantage of the present utility model is: when the organic substance in the needs removal water sample, at the mid-one deck filter paper of funnel, in the water sample hopper, by the resin filter in the filler tube, can remove the water sample organic matter.This filter has alleviated the experimental work amount, and has reduced experimental error, has saved experiment material.
Description of drawings
Accompanying drawing is used to provide further understanding of the present utility model, and constitutes the part of specification, is used from explanation the utility model with embodiment one of the present utility model, does not constitute restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the utility model funnel type glass core structure of filter schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in qualification the utility model.
Embodiment 1
As shown in Figure 1, funnel type glass sand core filter comprises conical hopper 1, straight tube 2, conical pipe 4, and the three connects from top to bottom, and the bottom position of straight tube 2 is provided with the glass core 3 of acid and alkali-resistance, in the straight tube 2, glass core 3 tops are filled with resin 5.Resin 5 is large aperture resinene CAD-40 type or XAD-2 type resin.
The filter total height is 213mm; The conical hopper height is 69mm, external diameter 78mm suitable for reading, end opening internal diameter 17mm, wall thickness 2.5mm; Funnel straight tube height 114mm, external diameter 14.5mm, internal diameter 14mm; Conical pipe height 30mm, external diameter 6mm suitable for reading, end opening 3mm, wall thickness 2.5mm; Glass core thickness 3.5mm, top external diameter 14mm, lower outer diameter 8mm.
This glass sand core filter can be used for measuring the nitrate nitrogen in the water sample, can remove the interference of organic matter to measuring in the water sample fully, and the analytic process of water sample nitrate nitrogen is greatly simplified, and has improved the speed of analysis and the reliability of data.
