Abstract
Description
technical field
[0001] The invention relates to a cleaning device for a dredging tool, in particular to a cleaning device for a dredging tool for dredging a sedimentation tank. Background technique
[0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. It has many types, which can be divided into three types: advection type, vertical flow type and radial flow type according to the direction of water flow in the pool. Considering the flocculation factor in the process of particle settling, it is assumed that the settling velocity of the particles changes at constant acceleration, and the initial settling velocity is set to zero. Considering the flow velocity distribution in the tube, the length of the inclined tube is: -d*tgθ where a is the acceleration of particle sinking velocity change, that is, a=du / dt The above three methods have their own shortcomings.
