[0002] Manufactured sand is an important material used in construction and engineering projects, widely applied in concrete preparation, road construction, and building engineering. It is primarily used to replace natural river sand due to the dwindling resources of natural river sand, while manufactured sand offers stable quality and a sustainable supply. However, manufactured sand faces several challenges in its application, one of the most significant being its high surface mud content and the difficulty in removing impurities. High surface mud content in manufactured sand affects its bonding with cement, reducing the strength and durability of concrete, thus impacting project quality. Furthermore, the small particle size of manufactured sand makes impurity removal difficult, hindering complete removal during production and application, further affecting concrete performance and project quality. This device was invented to address these challenges in sand washing, providing corresponding technical support for manufactured sand cleaning. Therefore, solving the problems of high surface mud content and difficult impurity removal in manufactured sand is crucial for improving its quality and promoting its application.

A stirring motor 2 is fixed inside the sand washing chamber 1, connected to a stirring spiral shaft 3 located inside the chamber. The stirring motor 2 drives the stirring spiral shaft 3 to rotate, which not only tumbles and cleans the manufactured sand inside but also pushes it forward. The outer side of the sand washing chamber 1 has an open structure, allowing the cleaned manufactured sand to be automatically removed from the chamber.

[0024] A water spray assembly is installed at the top of the sand washing chamber 1. The assembly includes a bracket 5 mounted above the chamber, with a flushing connection pipe 6 installed at the top of the bracket 5. The flushing connection pipe 6 has a hollow internal structure, and an inlet connector 7 is located on one side for connecting to a water supply pipe.
