[0036] The following is a detailed description of this experimental model with reference to the accompanying drawings:

[0037] Figure 1-4 The utility model shows a nano silver wire filtration and purification device, comprising:

[0038] The barrel body 3 has a barrel cover 1 on its upper cover. The barrel cover 1 is connected to a feed pipe 11. The other end of the feed pipe 11 is connected to a feed pump 2. The structure arranged in the barrel body 3 from top to bottom includes:

[0039] A filter plate 31 is detachably connected to the top opening of the barrel 3;

[0040] A first set of guide plates 33, which are detachably connected to the inner wall of the barrel 3;

[0041] A filtering and stirring barrel 35 is detachably connected to the inner wall of the barrel body 3 , and the opening of the filtering and stirring barrel 35 is arranged opposite to the first set of guide plates 33 ;

[0042] The filtering and stirring barrel 35 is provided with a plurality of stirring blades 42 , and the stirring blades 42 are rotatably connected to the rotating shaft 41 of the motor 4 ;

[0043] The second set of guide plates 36 is an inclined disc structure, and a scraper 43 is provided on the second set of guide plates 36. The scraper 43 is rotatably connected to the rotating shaft 41;

[0044] A liquid outlet pipe 5 is connected to the side wall of the barrel body 3 , and the other end of the liquid outlet pipe 5 is connected to a collecting barrel 6 .

[0045] Working principle:

[0046] The silver nanowires enter the barrel body 3 through the feed pipe 11 provided on the barrel cover 1. A detachable filter plate 31 is provided at the top of the barrel body 3. The filter plate 31 is used to perform a coarse filtration of the silver nanowires. Large impurities in the silver nanowire solution are retained on the filter plate 31. The detachable connection makes it easy to replace and clean the filter plate 31, preventing the silver nanowires from sticking and affecting subsequent filtration.

[0047] The coarsely filtered silver nanowire solution flows into the filtering and stirring barrel 35 in an orderly manner under the drainage function of the first set of guide plates 33. The stirring blades 43, driven by the motor 4, move in a circular motion around the rotating shaft 41, separating some of the remaining impurities that are difficult to separate through stirring. After stirring and separation, the impurities in the solution are retained in the filtering and stirring barrel 35. The detachable connection between the first set of guide plates 33 and the filtering and stirring barrel 35 also facilitates the overall cleaning, maintenance and replacement of the device.

[0048] The finely filtered silver nanowire solution flows orderly into the outlet of the liquid outlet pipe 5 under the drainage function of the second set of drainage plates 36. The scraper 43, driven by the motor 4, moves in a circular motion around the rotating shaft 41 on the second set of drainage plates 36 to prevent the silver nanowire solution from adhering to the inner wall of the barrel 3 and to accelerate the outflow of the liquid. The filtered silver nanowire solution flows through the liquid outlet pipe 5 into the collection barrel 6, completing the operation.

[0049] The feed pump 2 can control the flow rate of the nano silver wires entering the barrel 3, effectively reducing the generation of bubbles during the feeding process, and improving the filtering effect of the filter plate 31 by controlling the flow rate of the nano silver wires.

[0050] As in the above solution, T-shaped protrusions 311 are provided at both ends of the filter plate 31 , and a circle of inner grooves 312 are provided on the filter plate, and the inner grooves 312 are embedded and connected with the barrel body 3 .

[0051] Working principle:

[0052] The filter plate 31 is detachably connected to the top of the barrel 3 in the following manner: T-shaped protrusions 311 are added to both ends of the filter plate 31. There is a certain gap and an inner groove 312 between the T-shaped protrusion 311 and the filter plate 31. The thickness of the barrel 3 wall just fits the inner groove 312. In actual use, the operator only needs to hold the T-shaped protrusion 311 to complete the installation, removal and cleaning of the filter plate 31.

[0053] The barrel body 3 and the filter plate 31 are both open in design. Impurities in the air will pollute the purity of the entire device during long-term use. Adding a barrel cover 1 can effectively prevent dust from polluting the material source.

[0054] As in the above solution, the first set of guide plates 33 is a conical structure. The first set of guide plates 33 is fixed in contact with the barrel body through the first set of limiting rings 32 provided on the inner wall of the barrel body. The first set of guide plates 33 is arranged opposite to the opening of the filtering and stirring barrel 35.

[0055] The lower end of the second set of guide plates 36 is arranged opposite to the pipe opening of the liquid outlet pipe 5 .

[0056] Working principle:

[0057] After the first coarse filtration, the silver nanowire solution flows from the lower leak port into the opening of the filtration and stirring barrel 35 due to the conical structure of the first set of guide plates 33. This has the advantage of allowing the liquid filtered by the filter plates 31 to flow easily into the filtration and stirring barrel 35, preventing the liquid from splashing. At the same time, the solution is fixed in contact with the barrel body 3 by the first set of limiting rings 32, providing space for subsequent replacement and cleaning of the filtration and stirring barrel 35.

[0058] The silver nanowire solution after the second fine filtration leaves the liquid outlet pipe 5 under the drainage action of the second set of drainage plates 36, which has the advantage of convenient collection of the filtered liquid and avoids the problem of liquid accumulation at the bottom of the barrel and slow liquid recovery speed.

[0059] As in the above solution, a protruding ring 350 is provided on the top of the filter and stirring barrel 35, and a second set of limiting rings 34 are provided on the inner wall of the barrel body 3. The radius of the protruding ring 350 is equal to that of the second set of limiting rings 34. The protruding ring 35 is directly in contact with the second set of limiting rings 34 to achieve the fixing of the filter and stirring barrel 35.

[0060] The radius of the protruding circular ring 35 is smaller than the radius of the first set of limiting rings 32 .

[0061] Working principle:

[0062] The filtering and stirring barrel 35 is detachably connected to the inner wall of the barrel body 3 in the following manner: the protruding rings 350 at both ends are placed in direct contact with the second set of limiting rings 34, so that impurities cannot pass through the filter mesh structure set on the outer wall of the filtering and stirring barrel 35. At the same time, the detachable connection method facilitates the subsequent processing of impurities in the filtering and stirring barrel 35. To facilitate the removal of the filtering and stirring barrel 35, the radius of the protruding ring 35 is smaller than the radius of the first set of limiting rings 32.

[0063] As in the above solution, the liquid outlet pipe 5 is provided with a first set of control valves 50, and the feed pipe 11 is provided with a second set of control valves 20. The first set of control valves 20 is used to open or close the nano-solution that flows into the barrel 3, and the second set of control valves 50 is used to open or close the collection of the feed liquid.

[0064] As in the above solution, the second set of guide plates 36 and the rotating shaft 41 are connected by a sealed bearing 410, and the motor 4 is arranged under the second set of guide plates 36;

[0065] The radius of the scraper 43 is equal to the radius of the second set of guide plates 36 .

[0066] Working principle:

[0067] The scraper 43 moves in a circular motion on the second set of guide plates 36 with the rotating shaft 41 as the center. The radius of the scraper 43 is equal to the radius of the second set of guide plates 36, effectively scraping off the liquid that may be stuck to the barrel wall and accelerating the discharge speed.

[0068] The second set of guide plates 36 and the rotating shaft 41 are connected by a sealed bearing 410 , which effectively prevents the slurry from flowing into the motor 4 and affecting the normal operation of the motor 4 .

[0069] As in the above solution, the barrel body 3 is fixed by a metal frame 8 on all sides, and a placement table 80 is provided in the lower middle section of the metal frame 8, and the barrel body 3 is embedded in the placement table 80;

[0070] The collecting bucket 6 is fixed by supporting legs 7 .

[0071] Working principle:

[0072] The placement platform 80 at the lower middle section of the metal frame 8 ensures that the barrel body 3 is directly embedded in the metal frame 8 to complete the fixation, thereby preventing the bottom of the barrel body 3 from directly contacting the ground, and reducing damage to the barrel body 3 caused by factors such as ground moisture;

[0073] The collecting bucket 6 is arranged just below the barrel body 3, which can make it easier to collect the liquid. At the same time, the supporting feet 7 can be easily moved while preventing the bottom of the collecting bucket 6 from directly contacting the ground, thereby reducing damage to the bucket caused by factors such as damp ground.

[0074] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
