Description
Technical field
This utility model is related to the technical field of plumbing, more particularly to a kind of rotational flow grit chamber.
Background technology
Existing mode of removing sand typically has two kinds：
Horizontal flow type grit chamber is removed sand by the way of advection sedimentation, thus only operation of the sewage in setting pot when
Between be equal to or more than design the grains of sand sedimentation time, effect of just removing sand.But in actual applications, the water yield of water inlet and sand are measured not
Disconnected change.Therefore, when inflow is changed greatly, advection desilting effect is difficult to ensure that.
The characteristics of aerated grit chamber is to form the generation of water eddy flow by aeration to wash husky effect, is removed sand and Organic substance point with improving
From efficiency.But in practical application, as swirl velocity is difficult to determine, can only be controlled by adjusting aeration rate, and tolerance is excessive
Although can clean the grains of sand, tiny grains of sand clearance can be reduced；It is too small and cannot ensure swirl velocity, do not have aeration effect
Really.And during removing sand, have larger pollution to air.
Utility model content
For the deficiencies in the prior art, technical problem to be solved in the utility model is to provide a kind of sediment by rotational flow
Pond, even if this kind of setting pot water flow variation nor affects on desilting effect, and does not result in air pollution.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions：A kind of rotational flow grit chamber,
Including setting pot cell body, the cell body includes the sorting area on top, the Ji Shaqu at middle part and the husky bucket of the collection of bottom, the sorting area
Side is provided with water inlet, and the central authorities for sorting area are provided with outlet, and the cell body central authorities are provided with axial stirring paddle, the stirring paddle
Top is connected with driving means, the horizontally disposed propeller blade in middle part of stirring paddle, and the bottom of stirring paddle is near the husky bucket of collection, the pond
Body central authorities are additionally provided with axial loose sand pipe and sand extraction tube, and the husky bucket of collection of bottom, loose sand are stretched in the loose sand pipe and sand extraction tube lower end
The upper end of pipe and sand extraction tube is connected with air-lift device, and the air-lift device connects grit water separator.
Further, the air-lift device includes the aerator being connected with loose sand pipe, and the sand pump being connected with sand extraction tube.
Further, on the setting pot cell body, edge is provided with service bridge, the driving means, air-lift device, sand moisture
It is mounted on service bridge from device.
Further, the propeller blade adopts flat stream line style blade construction.
Further, the driving means are motor.
Further, the propeller blade is arranged at Ji Sha areas top.
Further, the Ji Sha areas are inverted trapezoidal.
Relative to prior art, the beneficial effects of the utility model are：
Rotational flow grit chamber of the present utility model using stirring paddle formed whirlpool, so as to make under cyclonic action the grains of sand settle into
The husky bucket of collection, therefore relative to horizontal flow type grit chamber, flow velocity will not be impacted to desilting effect substantially.This spiral-flow desilting side
Formula, is not limited only to the bulky grain grains of sand, also has good effect of settling to tiny gravel.The Ji Shaqu of inverted trapezoidal may also rely on sand
Grain deadweight is actively settled, and further speeds up settling efficiency.
Rotational flow grit chamber of the present utility model is by the husky bucket injecting compressed air of collection, carrying out loose sand, effectively increasing pressure
The service efficiency of contracting air, while by mixing wastewater with air liquid and the density contrast of water, effectively expanding suction Shamian Island, facilitates sand pump to carry
It is husky.It is compared with aerated grit chamber, more efficient, take out husky more thorough, while free from environmental pollution.
