Embodiment

[0022] The sand discharge funnel of present embodiment is as figure 1 , figure 2 and image 3 As shown, the water inlet culvert 1, the side wall 2, the funnel chamber 8, the flow regulating suspension plate 5, the overflow weir 6 and the side groove 7 are included, and the water inlet culvert 1 is connected to the upper part of the funnel chamber 8, and is connected to the top of 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 corridor 3, and the side wall 2 is connected to the upper part of the funnel chamber 8 to form a first circular arc section surrounding structure 10, The overflow weir 6 is connected to the upper part of the funnel chamber 8 to form a second circular arc segment surrounding structure 11. The height of the overflow weir 6 is lower than that of the side wall 2. The flow-regulating suspension pla...

Abstract

The invention provides a sand discharge funnel, which includes a water inlet culvert, a side wall, a funnel chamber, a flow regulating suspension plate, an overflow weir and a side groove. Cut, the bottom of the funnel chamber is provided with a sand-discharging bottom hole, and the sand-discharging bottom hole is connected with a sand-discharging corridor. The side wall is connected to the upper part of the funnel chamber to form a surrounding structure of the first arc segment. The overflow weir is connected to the upper part of the funnel chamber to form the surrounding structure of the second arc segment. The flow-regulating suspension plate has a proximal end and a distal end, the distal end is connected to the upper end of the overflow weir, the proximal end is close to the center of the funnel chamber, and the proximal end is higher than the distal end. The side trough is connected to one side of the overflow weir and the side wall to form a third circular arc segment surrounding structure, and the side trough is provided with a diversion channel opening. By improving the structure, the invention solves the problems of serious sediment deposition on the bottom of the funnel chamber and the suspension plate and high sand discharge water consumption rate, and improves the sand discharge efficiency of the sand discharge funnel.

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...
