Description

Technical Field

[0001] This utility model relates to the field of ceramsite screening technology, and in particular to a ceramsite sand screening device. Background Technology

[0002] Ceramsite sand is a lightweight, high-strength, porous functional inorganic non-metallic material made from clay, shale, fly ash, and other raw materials through crushing, mixing, granulation, and calcination (or sintering). Its core characteristics include low bulk density (500-1800 kg / m³), high compressive strength (≥35 MPa), high porosity (30%-50%), and resistance to acid and alkali corrosion. It also possesses thermal insulation, filtration, and adsorption functions, making it an environmentally friendly alternative to natural sand and gravel. In the production of ceramsite sand, screening (to ensure particle size uniformity) and drying (to control moisture content) are the two core processes. In traditional production, the drying and screening devices are independent; the wet ceramsite sand must first be fed into the drying equipment, and then transferred to the screening equipment after drying. This process not only occupies a large amount of production space and has high equipment investment costs, but also increases production time and material loss due to multiple transfers, severely restricting the continuity and economy of ceramsite sand production. To address this pain point, the development of a ceramsite sand screening device that integrates drying and screening is crucial for optimizing the production process, reducing costs, and improving efficiency. Utility Model Content

[0020] Working principle: The first motor 8 starts, driving the rotating rod 6 to rotate. The wet ceramsite sand in the feed hopper 5 enters the feed cylinder 3 through the feed pipe 4. The spiral blades 7 on the surface of the rotating rod 6 forcefully push the ceramsite sand into the screening machine body 1. The heating pipe 16 in the arc cavity 15 releases heat through the heat-transmitting plate 17 to dry the ceramsite sand in the screening machine body 1. The rotating rod 6 drives the rotating ring 11 and the filter cylinder 12 to rotate through the connecting plate 10. The U-shaped stirring plate 13 stirs the ceramsite sand synchronously, so that the material completes particle size screening through the filter cylinder 12 during the drying process. The second motor 20 drives the fan blade 21 to rotate, and forms a negative pressure through the fixed ring plate 18 and the fixed arc mesh 22 to quickly extract the water vapor generated during drying. After screening, the qualified ceramsite sand is discharged through the square hole 24 and the handle 27 to make the convex arc plate 26 slide along the convex arc groove 25, completing the whole process of "feeding → spiral pushing → synchronous drying and screening → dehumidification → discharge".
