[0002] Silver nitrate is an important chemical reagent, which is widely used in fields such as photography, electronics industry, and medicine. However, its production cost is relatively high. With the development of industry, a large amount of waste silver nitrate is discharged into the environment, causing serious environmental pollution. Recycling waste silver nitrate can reduce production costs, reduce environmental pollution, and achieve sustainable utilization of resources.

[0003] In the prior art, most silver nitrate needs to be filtered before recycling to separate the waste liquid from impurities. However, the silver nitrate waste liquid often contains a large amount of metal impurities such as copper, lead, and zinc. These metal impurities are likely to deposit on the filter medium during the filtering process, resulting in blockage of the filter medium and reduced filtering efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to provide a silver nitrate recovery filtering device. By setting a cleaning mechanism, the cleaning scraper on the rotating rod can quickly brush the inner wall of the filter cylinder, effectively scrape off the dirt adhered to the inner wall of the filter cylinder, and prevent the accumulation of dirt from hindering the normal filtering function of the filter cylinder, solving the problem that metal impurities are likely to deposit on the filter medium during the filtering process, resulting in blockage of the filter medium and reduced filtering efficiency.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the scope of protection of the present utility model.

[0027] Please refer to Figures 1-5 As shown, the utility model is a silver nitrate recovery and filtration device, including a tank body 1, on which a filtration mechanism 2 and a cleaning mechanism 3 are arranged. The filtration mechanism 2 includes a filtration component, a limiting component and a transmission component;

[0028] The filtration component includes a fixed disk 21 fixedly connected to the inner wall of the tank body 1. A groove 22 is opened on the fixed disk 21. The inner wall of the groove 22 is rotatably connected with a filter cylinder 23. The top surface of the filter cylinder 23 is fixedly connected with a connecting frame 24. The top surface of the connecting frame 24 is fixedly connected with a connecting sleeve 25. The bottom surface of the filter cylinder 23 is communicated with a first discharge pipe 26. Two limiting rings 27 are fixedly connected to the outer wall of the first discharge pipe 26. The two limiting rings 27 are respectively slidably connected with the inner bottom wall and the bottom surface of the tank body 1. The limiting component includes a fixed frame 28 fixedly connected to the top surface of the tank body 1. A rotating rod 281 is rotatably penetrated through the fixed frame 28. The rotating rod 281 is slidably connected with the inner wall of the connecting sleeve 25. A limiting ring 282 is fixedly connected to the outer wall of the rotating rod 281. The bottom surface of the limiting ring 282 is slidably connected with the top surface of the fixed frame 28. A support frame 283 is fixedly connected to the top surface of the tank body 1. A motor 284 is fixedly connected to the support frame 283. The top end of the rotating rod 281 is fixedly connected to the output end of the motor 284. The transmission component includes a first bevel gear 285 fixedly connected to the outer wall of the rotating rod 281. A second bevel gear 286 is rotatably connected to the front surface of a second fixed frame 288 fixedly connected to the top surface of the tank body 1. A third bevel gear 287 is fixedly connected to the outer wall of the connecting sleeve 25. The first bevel gear 285 meshes with the second bevel gear 286. The second bevel gear 286 meshes with the third bevel gear 287. By arranging the filtration mechanism 2, after the material is poured into the tank body 1 through the feed pipe 36, when the motor 284 on the support frame 283 is driven to drive the rotating rod 281 to rotate, the rotating rod 281 can be driven to rotate. Under the cooperation of the second bevel gear 286 and the third bevel gear 287, the connecting sleeve 25 is driven to rotate relatively, so that the filter cylinder 23 can be driven to rotate stably in the tank body 1. The centrifugal force generated by its high-speed rotation throws the material inside the filter cylinder 23 towards the filter cylinder wall and makes close contact with the precisely designed filter holes on the filter cylinder 23. This strong centrifugal action enables the liquid in the material to quickly pass through the filter holes, be collected by the tank body 1 and discharged through the second discharge pipe 37, while the solid particles are retained inside the filter cylinder 23, which can quickly separate the impurities in the silver nitrate solution, ensure that the filtered liquid is pure and pollution-free, and greatly improve the filtration efficiency.

[0029] The cleaning mechanism 3 includes a cleaning component and a discharging component. The cleaning component includes a number of fixed sleeves 31 fixedly connected to the outer wall of the rotating rod 281. The inner walls of the number of fixed sleeves 31 are all slidably connected with pistons 32. A piston rod 33 is fixedly connected to each of the number of pistons 32. The number of piston rods 33 respectively slide and extend to the outside of the number of fixed sleeves 31. The ends of the number of piston rods 33 are all fixedly connected with cleaning scrapers 34. The number of cleaning scrapers 34 are all in contact with the inner wall of the filter cartridge 23. Springs 35 are wound around the outer walls of the number of piston rods 33. One end of the spring 35 is fixedly connected with the piston 32, and the other end of the spring 35 is fixedly connected with the inner wall of the fixed sleeve 31. The discharging component includes a feed pipe 36 communicated and arranged on the top surface of the tank body 1. A second discharge pipe 37 is communicated and arranged on the bottom surface of the tank body 1. Electric valves 4 are arranged on both the first discharge pipe 26 and the second discharge pipe 37. By providing the cleaning mechanism 3, the rotating rod 281 and the filter cartridge 23 rotate relative to each other, so that the cleaning scrapers 34 on the rotating rod 281 can quickly brush the inner wall of the filter cartridge 23, effectively scrape off the dirt adhered to the inner wall of the filter cartridge 23, prevent the accumulation of dirt from hindering the normal filtering function of the filter cartridge 23, thereby prolonging the service life of the filter cartridge 23 and reducing the maintenance cost. At the same time, the design of the cleaning scraper 34 ensures the cleanliness and high efficiency of the scraping process, avoids secondary pollution, and provides a clean and safe working environment for the equipment.

[0030] A specific application of this embodiment is that the operating torque of the electric valve 4 is larger than that of an ordinary valve. The opening and closing action speed of the electric valve 4 can be adjusted. The structure is simple and easy to maintain. It can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. During the operation of a traditional pneumatic valve, due to the buffering characteristics of the gas itself, it is not easily damaged due to jamming, but a gas source must be available, and its control system is also more complex than that of the electric valve 4.

[0031] By providing a filtering mechanism 2, the fixed disk 21 and the groove 22 cooperate with each other to support the rotating filter cartridge 23. The first fixing frame 28 and the second limiting ring 282 cooperate with each other to support the rotating rotating rod 281. The two first limiting rings 27 cooperate with each other to support the rotating first discharge pipe 26. The second fixing frame 288 can support the rotating second bevel gear 286. After the material is poured into the tank body 1 through the feed pipe 36, when the motor 284 on the support frame 283 is driven to drive the rotating rod 281 to rotate, the rotating rod 281 can be driven to rotate. Under the cooperation of the second bevel gear 286 and the third bevel gear 287, the connecting sleeve 25 is driven to rotate relatively, so that the filter cartridge 23 can be driven to rotate stably in the tank body 1. The centrifugal force generated by its high-speed rotation throws the material inside the filter cartridge 23 towards the inner wall of the filter cartridge and makes close contact with the precisely designed filter holes on the filter cartridge 23. This strong centrifugal action enables the liquid in the material to quickly pass through the filter holes, be collected by the tank body 1 and discharged through the second discharge pipe 37, while the solid particles are retained inside the filter cartridge 23, which can quickly separate the impurities in the silver nitrate solution, ensure that the filtered liquid is pure and pollution-free, greatly improve the filtering efficiency, and the electric valve 4 can control the discharge speed of the material in the first discharge pipe 26 and the second discharge pipe 37, which is convenient for adjustment;

[0032] By providing a cleaning mechanism 3, springs 35 and pistons 32 are arranged in multiple fixed sleeves 31 on the rotating rod 281, so that the cleaning scraper 34 on the piston rod 33 can closely adhere to the inner wall of the filter cartridge 23. The rotating rod 281 and the filter cartridge 23 rotate relatively, so that the cleaning scraper 34 on the rotating rod 281 can quickly brush the inner wall of the filter cartridge 23, effectively scrape off the dirt adhered to the inner wall of the filter cartridge 23, prevent the accumulation of dirt from hindering the normal filtering function of the filter cartridge 23, thereby extending the service life of the filter cartridge 23 and reducing the maintenance cost. At the same time, the design of the cleaning scraper 34 ensures the cleanliness and high efficiency of the scraping process, avoids secondary pollution, and its mechanism cleverly arranges the gear transmission mechanism outside the barrel body, completely eliminating the risk of mechanical wear-generated impurities and lubricating grease contaminating the material, providing a clean and safe working environment for the equipment.
