Description

Technical Field

[0001] The utility model belongs to the technical field of silver powder production devices, and particularly relates to production equipment for photovoltaic silver powder. Background Art

[0002] In recent years, the photovoltaic industry, as a clean energy, has developed faster and faster, and silver powder with good conductivity has been used more and more widely on the front and back of solar cells. The simplest and most stable existing process is the reduction method of precipitation, filtration, washing and drying. The photovoltaic silver powder obtained by the reduction method has a spherical microscopic appearance and is mostly used on the front of solar panels. However, the back of solar panels often uses flaky photovoltaic silver powder to meet the photoelectric conversion efficiency and ensure solderability. However, in the prior art, after filtering and washing to obtain wet photovoltaic silver powder, it is necessary to enter a grinder to grind the material after cooling to obtain flaky photovoltaic silver powder that meets the requirements. During the use of the existing abrasive equipment, the particles in the abraded material are of different sizes, which affects the overall production efficiency and overall use effect of the manufacturer.

[0003] For example, the invention with announcement number CN115889788A discloses a photovoltaic silver powder production device with controllable particle size. In the technical solution of this patent, a stirring assembly is arranged inside the stirring chamber, and the motor drives the first grinding wheel, the push plate, the second grinding wheel and the stirring assembly to rotate synchronously through the transmission assembly. The first grinding wheel and the second grinding wheel are arranged inside the tank body. After the silver powder is initially ground by the first grinding wheel, it is then ground for the second time by the second grinding wheel. This can prevent the appearance of larger particles of the silver powder from affecting the stirring and mixing of the silver powder. When the stirring assembly is stirring and mixing, the stirring shaft will rotate on its own while the rotating shaft revolves, and the stirring shaft will also continuously move up and down while revolving. The material particles of this device after grinding are of different sizes and cannot be directly put into production. Therefore, a photovoltaic silver powder production device is proposed.
