A first air inlet pipe is arranged on the side wall of the filter tank 110 near the tank cover 120, and a dust collecting cover is connected through the first air inlet pipe. The silver powder dust collecting mechanism 20 includes a filter screen cover 210, a ring plate 220, and a flexible ring belt 230. The ring plate 220 is fixedly arranged on the inner wall of the filter tank 110, and the ring plate 220 and the filter tank 110 are fixed by welding. The flexible ring belt 230 is connected to the ring plate 220 and the funnel-shaped filter screen cover 210, and the flexible ring belt 230 can be a rubber belt. The top end of the connecting hose 270 is connected to the bottom of the filter screen cover 210, and the bottom end of the connecting hose 270 is connected to the discharge pipe 260. The discharge pipe 260 is disposed on the side wall of the filter tank 110. Preferably, a bracket 240 is fixed to the inner wall of the filter cover 210, and the bracket 240 and the filter cover 210 are fixed by bolts; and a vibration motor 250 is installed above the bracket 240. Preferably, a filter bag is laid on the filter cover.

[0027] When the gas with silver powder enters the filter tank 110 from the feed port. The filter cover 210 inside the filter tank 110 filters out the silver powder in the gas with silver powder, and the filtered gas is discharged from the outlet pipe 130. After the filtration is completed, the valve on the discharge pipe 260 is opened, and the silver powder filtered inside the filter cover 210 is finally discharged from the discharge pipe 260 through the connecting hose 270. At the same time of discharging, the vibration motor 250 is started, and the vibration motor 250 drives the bracket 240 and the filter cover 210 to vibrate, so that the silver powder filtered above the filter cover 210 can be discharged from the discharge pipe 260 more and better through the connecting hose 270. Therefore, the silver powder recovery device of the utility model can effectively recover and conveniently discharge and collect silver powder in gas and liquid, and has better applicability.

[0030] It should be noted that the specific model specifications of the vibration motor 250 and the booster pump 310 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail. The power supply and principle of the vibration motor 250 and the booster pump 310 are clear to those skilled in the art and will not be described in detail here.

[0031] The working principle of the silver powder recovery device is as follows: when in use, the gas with silver powder dust enters the filter tank 110 from the feed port. The filter screen cover 210 inside the filter tank 110 filters out the silver powder in the gas, and the filtered gas is discharged from the outlet pipe 130. After the filtration is completed, the valve on the discharge pipe 260 is opened, and the silver powder filtered by the filter screen cover 210 is finally discharged from the discharge pipe 260 through the connecting hose 270. At the same time as the discharge, the vibration motor 250 is started, and the vibration motor 250 drives the bracket 240 and the filter screen cover 210 to vibrate, so that the silver powder filtered above the filter screen cover 210 can be discharged from the discharge pipe 260 more and better.
