Technical Field

[0001] The utility model belongs to the technical field of sand mixing devices, and in particular relates to a sand mixing device used for mixing water glass and sea sand. Background Art

[0002] The sand mixer is a device that evenly mixes the components in the molding sand and effectively coats the surface of the sand particles with the binder. The sand mixer is the main equipment for the processing of foundry sand and the key equipment for obtaining qualified molding sand. The sand mixer evenly mixes the raw foundry sand (river sand, sea sand, weathered sand, etc.), binder, additive, water, etc. to make molding sand or core sand with certain properties. Among them, water glass is the most commonly used binder. Water glass is a general term for various polysilicate aqueous solutions.

[0003] The current sand mixing device can only stir the raw materials to mix them. However, when the foundry raw sand is stored, due to humidity, the raw sand is easy to stick together to form larger lumps of sand. After entering the sand mixing device, it cannot be fully mixed with other raw materials, resulting in poor quality of the raw materials after mixing.

[0004] Therefore, in order to solve the above problems, it is necessary to design a sand mixing device for mixing water glass and sea sand. Utility Model Content
