Description

Collar vortex stream sand discharge apparatus
Technical field
The utility model belongs to the artificial canal and goes up the sand discharge apparatus of installing, particularly collar vortex stream sand discharge apparatus.
Background technology
Northern area in China's water resource shortage, the river sand content is big, a large amount of silts enter channel with diversion, existing silt treating apparatus is arranged husky efficient than higher device, and a kind of " full beach volleyball hourglass bucket facility " arranged, its structure is the funnel that the bottom surface has tapering, in bottom center the funnel bottom outlet is being set, the water inlet that is connected with inlet channel is being set on hopper walls, the trend of inlet channel and the inwall of hopper walls are tangent.When current enter in the sand discharge funnel with tangential direction, the circular motion of vertical centre symmetry will take place, the current that lean on hopper walls zone into are for forcing the whirlpool, and leaning on into, the current of central area are free vortex.Lean on the current of funnel bottom into to have the radially flow velocity of the sensing hopper centre bottom outlet of certain orientation, when proportion than the heavy silt of water when water inlet enters funnel, will move to bottom outlet along helical trajectory, discharge through bottom outlet again.Owing to enter the outflow of the flow of funnel, make depth of water increasing in the funnel, and air funnel in funnel, occurs much larger than bottom outlet.The existence of air funnel reduces the sand surfing water yield, and the bottom outlet capability of sediment outflow strengthens.Therefore, sedimentation and the eliminating that sand discharge funnel helps silt is set.But,, will produce the circular motion of vertical centre symmetry because the basic principle of sand discharge funnel is when current enter in the sand discharge funnel with tangential direction.The structural form of sand discharge funnel is symmetrical, but influent stream is unidirectional, so the fluidised form in the funnel is asymmetric, the problem of thereupon bringing is the central axis that air funnel will depart from sand discharge funnel.Along with the size variation of influent stream, air funnel will deform or swing, the time regular meeting instability in air whirlpool appears.Unsettled air whirlpool can influence the fluidised form of free vortex, increases the husky water consumption of row.
Summary of the invention
The purpose of this utility model is to provide a kind of collar vortex stream sand discharge apparatus, can make the air whirlpool in the interior current free vortex of sand discharge funnel stable, no matter how the flow of inlet water size to change, do not influence the stable of air whirlpool, make the central lines of air whirlpool vertical line and sand discharge funnel.Make that three-phase stream (air-flow, current, sand drift) is very stable in free vortex, can more successfully silt be sent into the husky hole of row, reduce the husky water consumption of row.
The purpose of this utility model is achieved in that a kind of collar vortex stream sand discharge apparatus, comprise that the bottom surface has the sand discharge funnel of tapering, center in its bottom surface is being provided with bottom hole for sand flushing, the water inlet that is connected with inlet channel is being set on hopper walls, the trend of inlet channel and the inwall of hopper walls are tangent, the direction of hopper walls from inlet channel water inlet tangent line point of contact along current of sealing is involute curve letter wall, water inlet tangent line point of contact is to the recessed formation overflow weir in hopper walls top of 100 °-120 ° at water (flow) direction central angle, upper fixed in center, funnel bottom surface is installed with the letter of current stabilization circle, and the simple end of current stabilization circle letter is apart from the high annular gap of 50-100mm is being set between the funnel bottom surface.
The upper fixed of the utility model in center, funnel bottom surface is installed with the letter of current stabilization circle, makes the current in the sand discharge funnel be divided into center free vortex flow part and outer shroud circulation part.Bottom hole for sand flushing is positioned at the center of free vortex flow bottom.The simple end in the letter of current stabilization circle is provided with the high annular gap of 50-100mm, the sediment laden flow of the forced vortex that outer shroud circulation produces can symmetry the annular gap freedom of entry whirlpool from stable circle letter bottom, make that the air whirlpool in the free vortex is very stable, no matter how the flow of inlet water size changes, do not influence the stable of air whirlpool, make the center line in air whirlpool overlap fully with the center line of bottom hole for sand flushing.Make that three-phase stream (air-flow, current, sand drift) is very stable in free vortex, the three-dimensional flow that produces can more successfully be sent silt into bottom hole for sand flushing, is drained by the husky closed conduit of row, reach the purpose that obtains the husky amount of maximum row with minimum water consumption, reduce the husky water consumption of row.Because the hopper walls curve is involute shape, the outer shroud circulation that produces its mainly to act on be to reduce tangential flow velocity rapidly, make the downward sedimentation of silt, under the effect of bottom radial flow and gravity radial component, overcome action of centrifugal force, silt is moved to stable circle letter bottom.
In addition, because the carrying water in freedom of entry whirlpool has increased radially flow velocity of bottom by the annular gap of current stabilization circle letter bottom.Therefore, another effect of current stabilization circle letter is highly beneficial to the bottom hole for sand flushing migration to sand.Observe according to experiment, current are carried under one's arms after sand enters sand discharge apparatus, are subjected to the effect of several power, under the effect of circulation, a tangential force F are arranged 1, in action of gravity, a gravity G is arranged, because sand and water are made circular motion in the whirlpool, a centrifugal force F is arranged 2, because the sand discharge funnel bottom surface has tapering, the sand of motion sinks to the back, bottom under the effect of gravity G, and the radial component F of a gravity G is arranged 3, this power is opposite with the centrifugal force direction.Because bottom hole for sand flushing goes out stream a radially flow velocity that points to centre bore is arranged, under the effect of this flow velocity, sand also should have a radial load F 4Under the acting in conjunction of these several power, sand has the bottom surface precipitation of tapering and migrates and discharge to bottom hole for sand flushing at sand discharge funnel, is drained by the husky closed conduit of row.
