Description

Technical Field

[0002] Sand mixer is a device that mixes the components in the molding sand evenly and effectively covers the binder on the surface of the sand particles. The sand mixer uses the relative movement of the grinding wheel and the grinding disc to crush the material placed between the two by grinding and grinding. The sand mixer mixes the materials while crushing them. It is an ideal equipment for producing unburned bricks, lime sand bricks, cement bricks, refractory bricks, crushing and mixing fly ash, boiler slag, tailings slag and industrial waste residue as brick-making raw materials.

[0003] A sand mixer for casting processing with application number CN201921727969.3 comprises a mixing barrel, a bracket is fixedly connected to the edge of the lower outer surface of the mixing barrel, a stirring device is fixedly connected to the middle of the lower outer surface of the mixing barrel, a rotating shaft is provided on the upper outer surface of the stirring device, the rotating shaft passes through the mixing barrel and extends to the interior of the mixing barrel, a sealing gasket is provided between the mixing barrel and the rotating shaft, the rotating shaft and the sealing gasket are movably connected, a stirring shaft is fixedly connected to the upper outer surface of the rotating shaft, a stirring rod is fixedly connected to the upper outer surface of the stirring shaft, and a stirring tooth is fixedly connected to the end of the stirring rod away from the stirring shaft.

[0004] The above patent document has the beneficial effect of saving labor by providing a series of structures so that the device can improve the stability between the stirring rod and the stirring shaft through the reinforcing rod during use, and can initially filter the sand and gravel poured into the mixing barrel.

The incompletely closed annular filter net cannot fully filter the sand and gravel. Some irregular sand and gravel still fall into the filter barrel, resulting in a decrease in the filtration effect. The subsequent sand mixing process is affected and the quality of the sand mixing is greatly reduced. Utility Model Content
