Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of resin sand regeneration sand air separation and impurity removal devices, and specifically to a resin sand regeneration sand air separation and impurity removal device. BACKGROUND

[0002] In the foundry industry, resin sand molding process has been widely used due to its high casting precision, good surface quality and other significant advantages. However, this process generates a large amount of waste resin sand, which, if discarded directly, not only causes great waste of resources, but also has serious negative impact on the ecological environment. Therefore, recycling and utilizing waste resin sand has become a key measure for foundry enterprises to reduce production costs and achieve sustainable development.

[0003] In the resin sand recycling process, air separation and impurity removal is a very important link, which mainly separates dust, fine powder and light impurities from the recycled sand by means of wind, thereby improving the quality of the recycled sand. Currently, there are various resin sand regeneration sand air separation and impurity removal devices on the market, but they generally have poor air separation effect.

[0004] On the one hand, the air duct design of some air separation and impurity removal devices lacks scientificity and rationality. The shape, size and direction of the air duct are not properly set, which causes the airflow to flow in the air duct to increase in resistance, making it difficult to form a stable and uniform air field. This makes the recycled sand unable to fully contact with the airflow during air separation, and some dust and impurities cannot be effectively removed, resulting in incomplete air separation and affecting the purity of the recycled sand.

[0005] On the other hand, some existing air separation and impurity removal devices have limited control ability over wind speed and air volume. Different particle sizes and densities of recycled sand require different wind speeds and air volumes to achieve ideal air separation effect. However, these devices cannot accurately adjust according to the actual characteristics of the recycled sand, either the wind speed is too high, blowing away some qualified recycled sand, causing resource waste, or the wind speed is too low, failing to effectively separate dust and impurities, reducing air separation efficiency and quality.
