Abstract

[0031] Sand core 2, which is disposed at the outlet of the spiral activated carbon tube 1;
[0032] A filter frame 6 is disposed at the bottom of the spiral activated carbon tube 1. A porous filter disc 3 is disposed on the top of the inner side of the filter frame 6, and a double layer of filter paper 4 is disposed on the top of the porous filter disc 3.

[0037] The bottom of the outer side of the extension base 7 is fitted with an annular base 10, which is located on the inner side of the top opening of the liquid collection bottle 11.
[0038] The uppermost spiral activated carbon tube 1 is placed above the porous filter plate 3 of the filter frame 6. The filter frame 6 can be disassembled and separated from the extension base 7. The extension base 7 and the collection bottle 11 are used together by the support of the ring base 10, and can also be separated. In order to meet this requirement, the diameter error of all connections does not exceed 1mm.
[0039] The spiral activated carbon tube 1 has a funnel-shaped liquid inlet device at the top for easy sample pouring, and an inverted funnel-shaped sample outlet device at the bottom. At the end of the spiral tube, there is a sand core 2 to protect the activated carbon from being lost as the sample flows out.
[0040] The activated carbon filled in the spiral activated carbon tube 1 is in powder form;
[0041] When in use, double-layer filter paper 4 can be placed tightly above the porous filter disc 3 to block fine filter residue;
[0042] The filter frame 6 is equipped with a porous filter plate 3 and a perforated liquid flow device 5. The purpose is to slow down the liquid flow rate again so that the brine can fully contact the activated carbon to achieve a better adsorption effect.
[0043] The extension base 7 has a gap in the middle, that is, the part between the top of the activated carbon column 8 and the drain liquid flow device 5 is not filled.
[0044] Because of its detachable operation, the activated carbon column 8 can be regenerated or replaced after a certain period of use.
[0045] The activated carbon in activated carbon column 8 is granular activated carbon, with a larger particle size than that in spiral activated carbon tube 1.
[0046] Below the activated carbon column 8, there is gravel 9 to prevent the activated carbon from being lost;

[0049] The liquid collecting bottle 10 can be a wide-mouth liquid collecting bottle or a vacuum-type liquid collecting bottle.
[0050] The working principle of the spiral activated carbon adsorption filtration device provided by this utility model is as follows:
[0051] When in use, place the spiral activated carbon tube 1 on top of the filter frame 6, and make the bottom of the spiral activated carbon tube 1 fit into the inner side of the filter frame 6. At this time, the bottom of the spiral activated carbon tube 1 will abut against the top of the double-layer filter paper 4. Then, place the combination of the spiral activated carbon tube 1 and the filter frame 6 on the extension base 7, and then connect the bottom of the extension base 7 to the liquid collection bottle 11 through the annular base 10. The liquid flows from top to bottom, and finally achieves adsorption filtration.
[0052] Compared with related technologies, the spiral activated carbon adsorption filtration device provided by this utility model has the following beneficial effects:
[0053] The multi-layered filtration structure, consisting of a spiral activated carbon tube 1, a sand core 2, double-layer filter paper 4, an activated carbon column 8, and gravel 9, effectively removes thallium ions and other impurities from liquids, improving filtration accuracy and solving the problem of filtration difficulties caused by the precipitation and aggregation of thallium sulfide. It also avoids the release of toxic hydrogen sulfide gas from the hydrolysis of sodium sulfide solution in the sulfide precipitation method, protecting the health of operators and reducing environmental pollution. Compared to the stringent requirements for filter cloth selection in the sulfide precipitation method, this device has a simple structure and relatively lower requirements for the selection of components.
[0054] Second Embodiment
[0055] Please refer to the following: Figure 5 and Figure 6 Based on the spiral activated carbon adsorption filtration device provided in the first embodiment of this application, the second embodiment of this application proposes another spiral activated carbon adsorption filtration device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0056] Specifically, the difference in the spiral activated carbon adsorption filtration device provided in the second embodiment of this application is that the spiral activated carbon adsorption filtration device further includes a fixing ring 12, a plurality of support rods 13 are fixedly installed on the side of the fixing ring 12, a pad 14 is fixedly installed at the bottom of the plurality of support rods 13, an elastic support component 15 is provided on the top of the pad 14, and a collection frame 16 is provided on the top of the elastic support component 15.
[0057] The elastic support assembly 15 includes a mounting base 151, an extension column 152, a placement frame 153, and an elastic element 154. The extension column 152 is slidably connected to the inside of the top of the mounting base 151, the elastic element 154 is disposed at the bottom of the extension column 152, and the placement frame 153 is fixedly installed on the top of the extension column 152.
[0058] The collection frame 16 is disposed on the inner side of the placement frame 153, and the collection frame 16 is also disposed on the outer side of the liquid collection bottle 11.
[0059] The bottom of the mounting base 151 is fixedly mounted on the top of the pad 14.
[0060] A limiting structure is provided on the inner side of the mounting base 151. When in use, it can limit the extension column 152 and prevent the extension column 152 from being completely pushed out of the inner side of the mounting base 151.
[0061] The elasticity of the elastic element 154 ensures that the extension column 152 is always pushed upward during use.
[0062] The working principle of the spiral activated carbon adsorption filtration device provided by this utility model is as follows:
[0063] When in use, the user places the collection box 16 on the inner side of the placement box 153, and then pushes the placement box 153 downward, so that the bottom of the extension column 152 squeezes the elastic member 154, thereby moving the placement box 153 downward. Then the user places the collection bottle 11 on the inner side of the collection box 16, and then releases the placement box 153. At this time, the elasticity of the elastic member 154 will push the bottle mouth of the collection bottle 11 to connect with the bottom of the extension base 7.
[0064] After filtration is complete, the collection bottle 11 needs to be removed. When pouring out the liquid inside, first press the placement frame 153 downwards, and then remove the collection bottle 11. At this time, the remaining liquid inside the device will drip onto the inner side of the collection frame 16, and the dripping liquid can be collected through the collection frame 16.
[0065] Compared with related technologies, the spiral activated carbon adsorption filtration device provided by this utility model has the following beneficial effects:
[0066] The fixed ring 12, support rod 13 and pad 14 work together to ensure that the bottom of the pad 14 contacts the tabletop during use, and the support rod 13 is supported on the side of the fixed ring 12, increasing the range of support of the device and thus increasing the stability of the device. In addition, the collection box 16 can collect the dripping liquid during use, making it convenient for the user to handle later.
[0067] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
