[0002] In the casting process, water glass sand is widely used because of its colorless, odorless, low price, and easy operation.

[0003] However, with the development of green and clean casting technology, traditional water glass sand, as a unique casting material, is no longer suitable for current production process requirements due to its significant disadvantages such as low sand mold strength, high water content, easy moisture absorption, poor hardening in winter, and poor sand core collapsibility. The patent with application number CN201811081663.5 discloses a high-temperature resistant foundry sand and its production process. Its specification records "S1. Ball-mill bentonite, fly ash, zircon sand, corundum sand, high-alumina bauxite, glass fiber, magnesia sand, silica sand, water glass sand, cement, kaolin, silica powder, and carbon powder in the said proportion, which can pass through a 300-mesh standard sieve, dry and mix to obtain raw material A; S2. Heat the said proportion of water to 50°C, add corresponding proportions of adhesive, phenolic resin, and potassium dichromate, stir evenly, put it into a mixer and stir for 12 minutes to obtain mortar water, and keep the mixer speed at 500r / m; S3. Put the mortar water obtained in S2 and the raw material A obtained in S1 into a mixer, mix and stir for 40 minutes to obtain high-temperature resistant foundry sand".

The driving gear 502 is meshed with the transmission ring gear 40232, and the height of the transmission ring gear 40232 is greater than the height of the driving gear 502, so that when the transmission ring gear 40232 follows the rise and fall of the stirring frame 402, the driving gear 502 is always meshed with the transmission ring gear 40232. This scheme realizes transmission by setting a meshing driving gear 502 and a transmission gear ring 40232, and the meshing state can be maintained when the stirring frame 402 is raised or lowered; in addition, for the sake of stability, an intermediate gear ring with spur splines on both sides can be set between the driving gear 502 and the transmission gear ring 40232, the driving gear 502 is meshed with the teeth on the outer wall of the intermediate gear ring, and the transmission gear ring 40232 is meshed with the teeth on the inner wall of the intermediate gear ring, and then the intermediate gear ring is rotated and set at the bottom of the stirring chamber 401, so as to improve the stability of the entire transmission structure. In this embodiment, the driving motor 501 drives the driving gear 502 to rotate through a pulley assembly, that is, a group of pulleys are set on the output shaft of the driving motor 501 and the gear shaft of the driving gear 502, and a belt is set for transmission, the pulley is located outside the cover, and the cover is located at the bottom of the stirring chamber 401.

Since the stirring blade 4025 rotates, a certain gap needs to be reserved between it and the side wall of the stirring chamber 401. Uneven stirring is prone to occur in the reserved gap. In this solution, a stirring drum 403 driven by a stirring frame 402 is rotatably arranged on the side wall of the stirring chamber 401, and a spiral blade 4034 is arranged on the outer wall of the stirring drum 403 to stir the material upward.
