Description

Technical Field

[0001] The utility model relates to the technical field of sand mixing equipment, in particular to a coated sand mixing equipment. Background Technique

[0002] Coated sand refers to molding sand with a solid resin film on the surface of sand grains, which has the characteristics of high strength and high temperature resistance. It is the best molding material for automobiles, tractors, hydraulic presses, etc. In the preparation process of existing coated sand, sand materials and solid resin additives need to be mixed. In order to improve the mixing uniformity of the mixture, most of the mixtures are subjected to rotary mixing treatment, and the mixture is repeatedly stirred by a stirring component. However, in the actual production process, due to the high viscosity of the solid resin additive, the sand grains and the solid resin additive will adhere to the inner wall of the equipment during the stirring process, affecting its processing efficiency. Therefore, a coated sand mixing equipment is needed.

[0003] The prior art patent document with the publication number of CN205165723U provides a coated sand mixing equipment, including a sand mixer and a vibrating cooling screen. The vibrating cooling screen includes a screen body and a material plate arranged inside the screen body and inclined downward from front to back. An inlet connected to the discharge port of the sand mixer is arranged above the front end of the screen body. A cooling water channel for the circulation of cooling water is arranged on the material plate, so that the cooling water always cools the material plate, keeping the material plate at a relatively low temperature all the time. The material plate exchanges heat with the coated sand falling on it, which can better cool the coated sand. However, when the technology of CN205165723U is in operation, it cannot effectively prevent the situation of wall sticking during the sand mixing process, and at the same time, it cannot effectively improve the practicability of the device, and it cannot improve the feeding efficiency of the device.
