Avoid Segregate Design of Dry-mixed Mortar Truck
摘要
Abstract
To avoid the segregate phenomenon may occur of dry-mixed mortar in the process of pneumatic conveying, which seriously broken the original ratio of dry-mixed mortar, influenced the performance of mortar, a new model of discharge opening with multi-hole was designed. This model allowed dry-mixed mortar flowing out at different height. Hydromechanics analysis was carried on each discharging holes to find the relationship between the sizes of the holes and discharging amounts. The position and diameter of holes were designed to keep each hole discharging synchronously. The results show that this model realizes each plane discharging synchronously. The uniform factors caused by different heights and effects of segregate on discharging uniformed are eliminated. The efficiency of discharging is improved. By combining computing simulated and analyzed methods, area of each discharging hole on porous discharging cylinder is obtained. The discharging proportion is ensured to be accurate. The performance of mortar is guaranteed.关键词
