The utility model relates to a large-caliber copper filter disc vacuum suction filter which comprises a cabinet body, a cabinet door, a filter barrel, a filter disc, a filter disc filter paper pressing disc and a vacuum pump, and the filter disc is a copper filter disc made of brass materials; a stirring machine is mounted above the filter disc filter paper pressing disc and is vertically arranged, the lower end of a stirring shaft of the stirring machine extends into the filter disc filter paper pressing disc, and a horizontal scraping plate positioned in the filtering area is mounted at the lower end of the stirring shaft. The utility model relates to a vacuum suction filter with a large-caliber copper filter disc, which can be used for filtering filtrate containing zirconium element, and the zirconium element cannot chemically react with the filter disc. The solution is not polluted in the suction filtration process, and meanwhile, the filter disc and the filter cartridge have a good corrosion-resistant effect. A feasible scheme is provided for filtering the zirconium element, and the application scene of the vacuum suction filter is widened. According to the suction filter, the stirring function is added, a filter residue layer is prevented from being formed through stirring, the filtering efficiency and the use efficiency of equipment are improved, manual operation is reduced, and the time cost and the labor cost are saved.

This utility model relates to the field of petroleum mixing technology, specifically to a circulating mixing device for preventing sedimentation of petroleum additives. The device includes a mixing tank with a cover plate attached to its upper surface. A servo motor is fixedly connected to the upper surface of the cover plate, and the lower surface of the servo motor is fixedly mounted at the center of the upper surface of the cover plate. A fixing rod is fixedly connected to the output end of the servo motor through the inner wall of the cover plate. Multiple stirring rods and multiple stirring blades are fixedly connected to the surface of the fixing rod. A stirring disc is fixedly connected to the bottom end of the fixing rod. A first sampling tube is fixedly connected to the inner wall of the mixing tank, and a sampling cylinder is fixedly connected to the inner wall of the first sampling tube. In this utility model, when a piston moves upward within the sampling cylinder controlled by a pull rod, pressure draws a portion of the petroleum additive into a second sampling tube, facilitating sampling of the petroleum additive. The process is simple to operate and avoids contamination from other petroleum additives.
