Example Embodiment

[0021] Example

[0022] The sand funnel of this embodiment is such as figure 1 , figure 2 with image 3 As shown, it includes an inlet culvert 1, a side wall 2, a funnel chamber 8, a flow regulating suspension plate 5, an overflow weir 6 and a side groove 7. The inlet culvert 1 is connected to the upper part of the funnel chamber 8, and is connected to the funnel chamber 8. The outer circumference is tangent, the bottom of the funnel chamber 8 is provided with a sand discharge bottom hole 4, the sand discharge bottom hole 4 is connected with a sand discharge gallery 3, and the side wall 2 is connected to the upper part of the funnel chamber 8 to form a first arc segment surrounding structure 10. The overflow weir 6 is connected to the upper part of the funnel chamber 8 to form a second arc segment surrounding structure 11. The height of the overflow weir 6 is lower than the height of the side wall 2. The regulating suspension plate 5 has a proximal end and a distal end, and the ...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and relates to a sediment secondary treatment facility, in particular to a sand discharge funnel. Background technique [0002] Rivers often contain a lot of silt, especially in northern rivers, not only the silt content is high, the silt particles are also very fine, and the suspended sediment content is high. With the rapid development of production, the requirements for the quantity and quality of diverted water are getting higher and higher. Sand discharge funnel (that is, funnel-type full sand discharge technology) belongs to the centrifugal separation of water flow and gravity separation of water and sand with suspended fine particles of sediment, and is widely used for its high sand interception rate and low sand discharge water consumption rate. It is used in fields such as hydroelectric power generation, snail draining and lake control, sediment gold panning, river...
