Under the reaction force of the elastic support, the impact force of the silver powder when falling can be reduced. Moreover, when the silver powder falls again through the through hole, the distance between the silver powder and the filter element can be reduced.

[0018] In a specific embodiment, the side wall of the conical buffer plate is gap-matched with the inner wall of the cylinder, and at least three elastic support members are equidistantly arranged along the circumference of the conical buffer plate.

[0019] In the above implementation process, multiple elastic support members are provided to better support the conical buffer plate.

[0020] In a specific embodiment, the elastic support member includes a support plate and a spring, the support plate is connected to the inner wall of the cylinder, and two ends of the spring are fixedly connected to the lower end surface of the conical buffer plate and the upper end surface of the support plate respectively.

[0029] See also Figure 1-Figure 3 The present application provides a silver powder filtering device, comprising a cylinder 100 , a filter element 200 and a buffer mechanism 300 . The filter element 200 and the buffer mechanism 300 are both arranged inside the cylinder 100 .

[0030] The filter element 200 is installed inside the cylinder 100;

[0031] The buffer mechanism 300 includes a conical buffer plate 310 and an elastic support member 320.

[0032] In the above implementation process, when the solution containing silver powder is added into the cylinder 100 for filtering, the silver powder will first fall onto the surface of the conical buffer plate 310. Under the reaction force of the elastic support member 320, the impact force of the silver powder when falling can be reduced. Moreover, when the silver powder falls again through the through hole 330, the distance between the silver powder and the filter element 200 can be reduced. When the silver powder falls onto the surface of the filter element 200, the impact of the silver powder on the filter element 200 can be greatly reduced, thereby reducing the possibility of damage to the filter element 200 and making it easier to use the filter element 200.

[0033] In the above implementation process, the filtered waste liquid can be discharged through the discharge pipe 120, and the discharge pipe 120 can be an L-shaped pipe;

[0034] It can be understood that a discharge port is provided on the cylinder wall of the cylinder 100 above the filter element 200 , and the silver powder on the upper surface of the filter element 200 can be discharged through the discharge port on the surface of the cylinder 100 .

[0035] In a specific embodiment, an upper cover 130 is disposed at the top of the cylinder 100 . When the upper cover 130 is opened, the solution containing silver powder can be poured into the cylinder 100 .

[0036] In a specific embodiment, the filter element 200 includes an inner tube 210 and a filter screen 220 . The inner tube 210 is fixed inside the cylinder body 100 , and the filter screen 220 is installed on the upper surface of the inner tube 210 .

[0037] In the above implementation process, the inner tube 210 is used to connect the filter screen 220 and the cylinder body 100 together, and the filter screen 220 is used to support the filter bag and filter the silver powder.

[0038] In a specific implementation manner, a support protrusion 230 is disposed inside the inner tube 210 , and the upper end surface of the support protrusion 230 is fixedly connected to the lower end surface of the filter screen 220 .

[0039] In the above implementation process, the support protrusion 230 is provided to improve the pressure resistance of the filter 220 and reduce the damage of the filter 220 under the impact of silver powder.

[0040] In a specific implementation manner, at least two buffer mechanisms 300 are arranged at intervals along the height direction of the cylinder 100, and two upper and lower adjacent through holes 330 are staggered.

[0041] In the above implementation process, multiple buffer mechanisms 300 are provided to reduce the impact force when the silver powder falls.

[0045] In the above implementation process, the support plate 321 can support the conical buffer plate 310 by supporting the spring 322. When the silver powder falls onto the surface of the conical buffer plate 310, it will squeeze the spring 322. Under the reaction force of the spring 322, the impact of the silver powder falling can be reduced.

[0046] Specifically, when the silver powder filtering device is in use, a solution containing silver powder is added into the cylinder 100, and the silver powder will first fall onto the surface of the conical buffer plate 310. Under the reaction force of the elastic support member 320, the impact force of the silver powder when falling can be reduced. Moreover, when the silver powder falls again through the through hole 330, the distance between the silver powder and the filter element 200 can be reduced. When the silver powder falls onto the surface of the filter element 200, the impact of the silver powder on the filter element 200 can be greatly reduced, thereby reducing the possibility of damage to the filter element 200 and making it easier to use the filter element 200.
