Description
Technical field
The utility model relates to a kind of device that is used for the water treatment building uniform water distribution, especially is fit to the uniform water distribution device between each processing is constructed in the sewage work.
Background technology
At present, the water distribution mode that is used between each processing is constructed in the sewage work has the perforated pipe water distribution, wears the water distribution of spray wall, distributing flue, water distribution weir, these water dispensing apparatus all are to utilize hydraulic principle, reach the purpose of uniform water distribution, but owing to can not come setting device according to the variation of water levels of upstream and downstream, so all can not obtain gratifying water distribution effect.If adopt supermatic fluid level control device uniform water distribution, can carry out setting device according to the variation of water levels of upstream and downstream and reach very high water distribution precision, but these plant investments are big, the energy consumption height.
Summary of the invention
Shortcoming at prior art, technical problem to be solved in the utility model provides a kind of uniform water distribution device, this water dispensing apparatus can not only reach the purpose of uniform water distribution, and can automatic easily variation change with water levels of upstream and downstream, can guarantee at different time, the different positions even water distribution, this water dispensing apparatus investment is little, energy consumption is low, water distribution precision height.
The technical scheme that its technical problem of solution of the present utility model is adopted: a kind of uniform water distribution device, it comprises distributing flue, a movable weir plate that changes with change of level is set on described distributing flue water distribution direction, and described movable weir plate two ends are inserted respectively in set two the vertically parallel board slots of described distributing flue two walls; The be rigidly connected ball float of some amount of the bottom of described movable weir plate, the origin or beginning of described weir plate and the terminal top top end face of controlling the described movable weir plate of ball float that respectively is rigidly connected is parallel with the canal bottom surface of distributing flue; The downstream of described canal for water distribution water distribution direction is provided with the weir front apron.
Ball float number=[(weir plate weight-weir plate buoyancy)/ball float buoyancy]-1 that described movable weir plate bottom connects.
The long thin plate of described movable weir plate for making with the glass reinforced plastic of high-strength low-density.
Described board slot inwall is provided with rubber pad, embedding pulley on the described rubber pad.
The thickness of described movable weir plate is 8-40mm, the depth of water-weir head-change of level height in the height=water channel of movable weir plate.
The channel of described distributing flue reduces to terminal section gradually from feed-water end.
The beneficial effects of the utility model:
1, movable weir plate origin or beginning described in the utility model is inserted respectively in set two the vertically parallel board slots of described distributing flue two walls with terminal; Described board slot restraint weir plate moves with water (flow) direction, and movable weir plate can be the vertical direction free movement along the board slot direction.
2, that rubber pad is set is water-tight to guarantee for board slot inwall described in the utility model, and the embedding pulley reduces movable weir plate and the board slot frictional force in vertical direction on rubber pad.
3. the bottom of the movable weir plate described in the utility model ball float of some amount that is rigidly connected, to increase the buoyancy of weir plate, make buoyancy be slightly less than gravity. difference is less than the buoyancy of 2 ball floats, a ball float respectively is rigidly connected at the origin or beginning of movable weir plate and terminal top, when fixing water level, because the weight of movable weir plate is fixed, required suspension buoyancy also is fixed.The buoyancy that movable weir plate that floods and ball float are subjected to is fixed, controls the given volume that ball float surfaces so, and being same as control ball float and movable weir plate is the firm downlink connection in top, and the depth of immersion on movable weir plate top will remain unchanged.When the change of level in the distributing flue, ball float drive activity weir plate is followed change of level.The top end face of described movable weir plate is parallel with the canal bottom surface of distributing flue, has guaranteed that the movable weir plate top gradient and distributing flue bottom hydraulic slope is identical, and it is identical to go up the head that movable weir plate pushes up so along its length, according to hydraulic principle:
Weir head is identical, and the weir crest shape is identical, and water flow is identical.Because along with the water distribution of distributing flue, the water yield in the water channel slowly reduces, basic identical for the flow velocity on the transverse section that guarantees channel, channel reduces to terminal section gradually from feed-water end.
4, uniform water distribution device of the present utility model can not only reach along the purpose of distributing flue length direction uniform water distribution, and can change with upper pond level automatically easily, can guarantee the homogeneity of water distribution.
5, uniform water distribution device of the present utility model does not need energy consumption, and cost is low.
