Description

Technical Field

[0001] The utility model relates to the technical field of stirring, in particular to a modified water glass heating stirring tank. Background Art

[0002] The primary material for fused sand molds is silica sand, mixed with modified water glass as a binder and glycerol diacetate as a resin-hardening curing agent. The modification of water glass is based on the drawbacks of the water glass binder during sand mold production. To address these drawbacks, a corresponding liquid modifier is added to the water glass, thereby compensating for the inherent drawbacks.

[0003] Since water glass will form sediment when it is in a static state, the sediment will clog the pipeline over time, affecting production. Therefore, the modified water glass must have a stirring function during use to prevent the sediment from sinking. Furthermore, the viscosity of water glass varies at different temperatures in different seasons. In winter, the viscosity of water glass is too high, making it difficult to pass through the pipeline. Therefore, the water glass needs to be heated to keep the viscosity controllable. However, most existing mixing tanks are mechanically stirred by stirring blades. During the stirring process, the water glass in the mixing tank forms a vortex, causing the sediment to accumulate at the bottom center of the mixing tank. Even with this method, the sediment still sinks, resulting in poor stirring effect. In addition, existing mixing tanks also have defects such as being difficult to clean and difficult to quantitatively dose. In response to this, the utility model provides a modified water glass heating mixing tank to overcome the above technical problems. Utility Model Content
