Description

Zinc powder sedimentation-preventing filter equipment Technical Field The utility model relates to zinc powder sedimentation-preventing filtering equipment. Background At present, in the industrial production process involving the use of zinc powder, such as the industries of paint, batteries, chemical industry and the like, zinc powder is easy to generate sedimentation phenomenon in a liquid system due to the special physical and chemical properties. The zinc powder sedimentation not only can influence the uniformity and quality of the product, but also can bring difficulty to subsequent filtering operation, so that the problems of reduced filtering efficiency, increased filtering cost, unstable product quality and the like are caused. Therefore, a device capable of simultaneously realizing sedimentation prevention and efficient filtration of zinc powder is needed to meet the demands of industrial production. Disclosure of utility model Therefore, the utility model provides zinc powder sedimentation-preventing filter equipment aiming at the problems. The zinc powder sedimentation-preventing filter equipment comprises a container and a stirring assembly, wherein the stirring assembly comprises a rotating shaft rotatably arranged in the container, a stirring disc fixed at the lower part of the rotating shaft and a stirring paddle fixed at the upper part of the rotating shaft, the stirring disc comprises a disc, upper blades and lower blades which are arranged at the periphery of the disc at intervals, a plurality of hollows are arranged on the disc at intervals around the axis, a drainage plate is obliquely arranged on the lower surface of the disc at the hollows along the rotating direction, and a filtering port is formed in the bottom or the side part of the container and is connected with the filtering assembly. Further improves, the upper blade and the lower blade are arranged in a staggered way. Further improved, the upper blade comprises an upper extending part extending outwards from the periphery of the disc and an upper bending part bending upwards from the outer end of the upper extending part, the lower blade comprises a lower extending part extending outwards from the periphery of the disc and a lower bending part bending downwards from the outer end of the lower extending part, and the upper extending part and the lower extending part are in a triangular structure. Further improved, the hollowed-out parts are triangular. Further improved, the length of the upper blade is longer than that of the lower blade.
