Description

Technical Field

[0002] Concrete aggregates usually come from natural or artificial materials, including crushed stone and sand. Before being used to prepare concrete, aggregates need to be cleaned and graded to ensure that they meet various indicators of concrete quality. The main purpose of the cleaning process is to remove mud, dust and other impurities in the aggregates. Traditional aggregate cleaning equipment mainly relies on screen filtration and large amounts of water to achieve the cleaning goal.

However, the filter frame of this aggregate cleaning and filtering device is relatively large in volume. Although a rotating assembly is arranged at the center of the filter frame for stirring the concrete aggregate placed in the filter frame, it is difficult for part of the concrete aggregate located in the middle of the filter frame to be stirred to the inner wall of the filter frame to fully contact the water body outside the filter frame, and the impurities on the aggregate are difficult to be cleaned by the water body, and it is not convenient to quickly empty the water body in the cleaning device, which needs further improvement.

[0004] Therefore, an aggregate cleaning and filtering device for producing concrete is proposed, which can improve the cleaning effect of concrete aggregates and facilitate the rapid emptying of water in the cleaning device. Utility Model Content
