Description

Technical Field

[0001] The present application relates to the technical field of concrete screening, and in particular to a concrete screening device. Background Art

[0002] Concrete, this seemingly simple word, carries the cornerstone status of the modern construction industry. From high-rise buildings to country roads, from bridges and tunnels to reservoirs and dams, concrete is everywhere and has become a solid foundation supporting the progress of human civilization. Concrete is a composite material mixed with water, aggregates (such as sand and gravel) and cementitious materials (usually cement). Its strength, durability and plasticity make it one of the most commonly used materials in the construction industry. By adjusting the mix ratio of concrete and using different types of aggregates and cementitious materials, concrete that meets various engineering needs can be produced. In general, as the cornerstone of the construction industry, concrete has made a huge contribution to the progress of human civilization.

[0003] Patent publication number "CN219923706U" discloses "a recycled concrete aggregate screening device", including a screening box, a top wall of the screening box is provided with a discharge port, a top wall of the discharge port is fixedly connected with a discharge pipe, a top wall of the discharge pipe is connected with a feed hopper, and a screening assembly is installed in the inner cavity of the screening box, which relates to the field of aggregate screening technology; the recycled concrete aggregate screening device drives the screening box to vibrate by a vibration motor, and puts the aggregate into the feed hopper, the discharge pipe and the discharge port until it enters the screening box, and the aggregate passes through the screening plate to press down the screening plate and the spring, and the spring drives the screening plate to reset and the vibration motor to work, and the aggregate is quickly screened out according to the screening holes on the screening plate. The aggregate particles are sequentially screened out, and the aggregate is discharged from the discharge port through the guide plate, so that when the concrete aggregate is screened, the screening work can be continuously performed, and the aggregate is screened according to different sizes, which can improve the work efficiency of the entire screening.

[0004] In the aggregate screening process, if the device in the above patent does not perform proper crushing on the aggregates, but directly repeatedly screens the screened materials, the screening efficiency will be significantly reduced, and it will be difficult to achieve the expected screening target. In addition, this kind of cyclic screening not only wastes time and resources, but may also have an adverse effect on the performance of the final product. Therefore, in order to ensure that the aggregates meet the established usage standards, the oversized aggregate particles should be crushed first and then screened.

[0005] Therefore, the utility model provides a concrete screening device to solve the above problems. Utility Model Content
