Background

The sand mixer is a device for uniformly mixing the components in the molding sand and effectively and uniformly coating the adhesive on the surface of the sand. The sand mixer is used as key equipment in the casting process, and is a key factor for controlling the quality and cost of molding sand. The sand mixer can be divided into a twisting wheel type sand mixer, a vane type sand mixer and a countercurrent type sand mixer, wherein the vane type sand mixer adopts a rotary vane to mix raw sand, and after the sand mixing operation is completed, a path of a hardening agent and a binder needs to be cut off immediately, and meanwhile, residual molding sand in the sand mixer needs to be cleaned.

The hot method film coating process is to add the raw sand heated to a certain temperature into a sand mixer, add the ingredients such as resin, lubricant, curing agent and the like in a specific amount in sequence in the sand mixing process to carry out sand mixing operation, and then carry out sand discharging, crushing, screening and cooling to prepare the dry thermosetting molding sand containing the latent curing agent, lubricant and binder. Therefore, the stirring effect of the sand mixer can directly influence the smoothness of the resin coating of the precoated sand, thereby influencing the strength, the fluidity, the formability, the production efficiency and the like of the precoated sand.

In view of the above-mentioned related art, the inventors believe that in the process of mixing and stirring the first sand and the additive by the blade-type sand mixer, the materials are more and the quality and density of the various materials are uneven, so that the materials are easy to mix unevenly and the mixing efficiency is low in the stirring process. In addition, the mixture contains components such as a curing agent and a binder, so that materials can be adhered to the inner wall of the sand mixer after long-term use, which causes difficulty in cleaning and influences the production efficiency of the sand mixer.
