Abstract

The reverse flow inclined plate tail water collecting sedimentation tank is characterized in that a water distribution weir is arranged at the tail end of the sedimentation tank of the reverse flow inclined plate, the water collecting channel is formed, the water depth of the upper water area and the water depth of the lower water area of the inclined plate are the same, the water collecting channel and the water collecting channel are arranged at the tail end of the sedimentation tank of the reverse flow inclined plate, the water collecting channel and the water distribution weir are arranged at the tail end of the sedimentation tank, the water depth of the upper water area and the water depth of the lower water area of the inclined plate are the same, water flow is guaranteed to enter the water collecting channel through the water distribution weir, the generated water head loss is the same, short-edge water distribution can be realized under the condition that the long.

Description

The reverse flow swash plate afterbody sedimentation basin that catchments

The utility model is to belong to water treatment facilities.

At present, water leg is all established at reverse flow swash plate (inclined tube) sedimentation basin top, and the water that flows out from swash plate concentrates in these water legs, is collected in the channel that catchments by water leg and discharges.Arrange that like this it is uneven that the head vat tail load-bearing of sedimentation basin pond distributes.Short from the distance that the water of sedimentation basin pond head outflow is walked, the loss of flood peak is little; The distance that the water that goes out from the pond wake flow is walked is long, and the loss of flood peak is big.So just cause a pond water yield big, the little phenomenon of pond tail water yield.So the ramp type sedimentation basin all adopts long limit water distribution at present, this mode arranges to sedimentation basin and causes certain trouble that floor space strengthens, the plant area increasing.The sedimentation basin top is provided with water leg, has also increased the cost of sedimentation basin, makes local water distribution inequality; The water that is located immediately at the water leg below flows into water leg will be changeed the curved of one 90 degree, hydraulic resistance strengthens, and causes the upflow velocity of these regional swash plates to reduce, and flow velocity is gone up in other area to be increased, flow velocity reduces regional desilting area is not fully used, and flow velocity adds the major region effluent quality to be worsened.

The purpose of this utility model is to propose a kind of reverse flow swash plate afterbody sedimentation basin that catchments, tail end place at sedimentation basin is provided with braiding channel, make current enter braiding channel by the cloth mill weir of braiding channel, to enter the distance that braiding channel flows through identical for the cloth mill weir so just to guarantee to flow through current by any one path, the loss of flood peak is also identical, make the water distribution of sedimentation basin even, realize the minor face water distribution, reduce investment.

The utility model is made up of pool 7, mud accumulation area 8 under pool 6, the swash plate on braiding channel, cloth mill weir 2, swash plate 3, transition region 4, perforation tracery wall 5, the swash plate, as shown in Figure 1, 2; It is characterized in that: the tail end place at the sedimentation basin of reverse flow swash plate 3 is provided with cloth mill weir 2, braiding channel 1, and makes the degree of depth of the upper and lower pool of

swash plate

6,7 water identical.

Operation principle of the present utility model: water leg is all established at the top of the sedimentation basin of general reverse flow swash plate, causes local water distribution inequality, and hydraulic resistance strengthens; And this device is to be provided with cloth mill weir 2 and braiding channel 1 at the tail end place of inclined-plate clarifying basin, remove the top water leg of the sedimentation basin of general reverse flow swash plate, current in the pond all enter braiding channel 1 by cloth mill weir 2, and the water distribution manner at sedimentation basin is on the swash plate 3, following

pool

6,7 water depth is identical, so just guarantee that current are all basic identical by any one path distance that the cloth mill weir flow through of flowing through, the loss of flood peak of its generation is also basic identical, therefore the uniformity of water distribution that also just keeps sedimentation basin, under the situation that particularly suitable sedimentation basin length is grown very much, can realize the minor face water distribution.

The utility model compared with prior art, because this device is provided with cloth mill weir and braiding channel at the tail end of reverse flow inclined-plate clarifying basin, and the flow depth that has guaranteed the upper and lower pool of swash plate is identical, make the current that flow out by swash plate enter braiding channel through the cloth mill weir, its distance is identical, and the loss of flood peak of generation is basic identical, can be implemented under the very long situation in the long limit of sedimentation basin and the minor face water distribution, the difficulty of reducing the loss and economizing on water improves the effect of handling water.

Fig. 2 is the A-A profile of the utility model Fig. 1.

Embodiment of the present utility model:

The utility model is made up of pool 7, mud accumulation area 8 under pool 6, the swash plate on braiding channel 1, cloth mill weir 2, swash plate 3, transition region 4, perforation tracery wall 5, the swash plate, wherein braiding channel 1, transition region 4, perforation tracery wall 5, mud accumulation area 8 usefulness armored concrete are made plastic injection-moulded the forming of swash plate 3 usefulness.

Braiding channel 1, cloth mill weir 2 place the tail end place of sedimentation basin, transition region 4, perforation tracery wall 5 place sedimentation basin head place, mud accumulation area 8 is positioned at the bottom of sedimentation basin, swash plate 3 under pool 6, the swash plate on the swash plate of sedimentation basin between the pool 7 and mud accumulation area 8 above, and make the water depth in the upper and

lower pool

6,7 of swash plate identical, form the reverse flow swash plate afterbody sedimentation basin that catchments, in this sedimentation basin, can realize the minor face water distribution.

Claims

1, a kind of reverse flow swash plate afterbody sedimentation basin that catchments, by transition region, swash plate, mud accumulation area, it is characterized in that: the tail end place at the sedimentation basin of reverse flow swash plate (3) is provided with cloth mill weir (2), braiding channel (1), and makes the water depth of the upper and lower pool of swash plate (6), (7) identical.
