Sand discharge funnel
The invention provides a sand discharge funnel. The sand discharge funnel comprises a water inlet culvert, an edge wall, a funnel chamber, a flow adjusting suspension plate, an overflow weir and a side groove; the water inlet culvert is connected to the upper portion of the funnel chamber, and is tangential to the outer periphery of the funnel chamber; and a sand discharge bottom hole is formed inthe bottom of the funnel chamber, and is connected to a sand discharge gallery. The edge wall is connected to the upper portion of the funnel chamber to form a first arc section envelope structure. The overflow weir is connected to the upper portion of the funnel chamber to form a second arc section envelope structure. The flow adjusting suspension plate is provided with a center-near end and a center-far end; the center-far end is connected to the upper end of the overflow weir; and the center-near end is near the center of the funnel chamber and higher than the center-far end. The side groove is connected to one side of the overflow weir to form a third arc section envelope structure with the edge wall; and a drainage ditch port is formed in the side groove. Through structural improvement, the problems of bad sediment accumulation at the bottom of the funnel chamber and on the suspension plate and high sand discharge water consumption rate are solved, and the sand discharge efficiency of the sand discharge funnel is improved.
本发明提供一种排沙漏斗，包括进水涵洞、边墙、漏斗室、调流悬板、溢流堰和侧槽，进水涵洞连接在漏斗室的上部，且与漏斗室的外圆周相切，漏斗室的底部开有排沙底孔，排沙底孔连接有排沙廊道。边墙连接在漏斗室上部形成第一圆弧段包围结构。溢流堰连接在漏斗室上部形成第二圆弧段包围结构。调流悬板有近心端和远心端，远心端连接在溢流堰的上端，近心端靠近漏斗室的中心，近心端高于远心端。侧槽连接在溢流堰一侧与边墙形成第三圆弧段包围结构，侧槽上开有引水渠道口。本发明通过对结构的改进，解决了漏斗室底部和悬板上泥沙淤积严重以及排沙耗水率高的问题，提高了排沙漏斗的排沙效率。
