Description
Technical field
This utility model belongs to technical field of sewage, is specifically related to a kind of advection sedimentation being conducive to deslagging
Pond slag-draining device.
Background technology
A part for horizontal sedimentation tank structure is the facility (scum silica frost arranging in the front end of water outlet weir notch and discharging scum silica frost
Groove), by setting slag-scraper in pond, scum silica frost is scraped to scum trough and be then exhausted from.
The horizontal sedimentation tank of the most a lot of engineering projects does not all have water level control apparatus, but according to Design Theory
Requirement, use level altitude, and the height of water level designed often with practical operation situation difference.Scrape slag
Effect depends primarily on the water level of horizontal sedimentation tank and the difference in height on scum trough upstream face summit.When entering streamflow
During excessive, impeded drainage, advection sedimentation pool water level raises, and behind scum trough upstream face summit, can cause
Large amount of sewage directly flows out from scum trough with scum silica frost, causes follow-up solid-liquid separation unfavorable；Otherwise, when advection sinks

Not only affect the work hygiene situation of horizontal sedimentation tank, even cause pool inner water body anaerobism time serious, after impact
Continuous process.Run the debugging initial stage especially for horizontal sedimentation tank, or scum silica frost amount is bigger with water quality seasonal variations
Situation, regulate with greater need for by water level repeatedly, determine actual motion optimum level of water, to ensure that surface is floated
Slag is scraped in time into scum trough.
Additionally, tradition scum trough upstream face is typically by being perpendicular to horizontal plane design, installing, often occur floating
Slag has been scraped to slag chute mouth, is but blocked by slag chute upstream face side, it is impossible to enter slag chute smoothly, especially
Less or the scum silica frost of relatively thickness, the most blocked at slag chute upstream face.Further, the bottom of a lot of slag chutes is all
Use rectangular channel level design, be extremely unfavorable for that relatively big and thickness the scum silica frost of proportion is discharged.Thus need artificial
The scum silica frost do not discharged in time in cleaning slag chute upstream face scum silica frost and slag chute, adds the labor intensity of operator,
Also increase potential safety hazard simultaneously.
