Description
Technical field
The utility model is suitable for dystrophication bed mud and industrializes disposal field, more particularly to a kind of improvement dystrophication bottom
The device of mud settling property.
Background technology
Existing dystrophication bed mud industrialization disposal system is typically to be directly entered after sand setting is handled to the disposal of bed mud
Sedimentation basin carry out mud-water separation, practice have shown that this method it is higher to clay content mud effect of settling it is poor, especially continuous
Sedimentation basin water outlet clay content is higher during operation, is unfavorable for subsequent purification of water quality.
Coagulation/flocculation technique promotes sludge to take off steady cohesion, is widely used in terms of improving settling property, common coagulation mode
Including blender action of forced stirring.It is required according to outdoor water supply and sewerage design manual, distance of the propeller-blade away from pool wall is not more than
0.25m, if merely using this method, when pool wall width is larger, to reach enough stirring intensity to diameter of propeller blade requirement compared with
Height, the power of motor that need to be equipped with, size are larger, installation trouble, and later stage maintenance is difficult.
Since setting pot overflow mud possesses certain first kinetic energy and position potential energy, with the drop of mud, potential energy is gradual
Kinetic energy is converted into, interior energy is converted kinetic energy by energy dissipating effect, then can strengthen the interaction inside mud, it is mixed to reach reinforcing
The effect of conjunction.
The content of the invention
Coagulating basin is transformed based on original setting pot overflow slurry collecting pond the purpose of this utility model is to provide one kind,
PAC can well-mixed new coagulation/flocculation plant with mud.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of improvement dystrophication bed mud settleability
The device of energy, which is characterized in that the coagulating basin includes mud-collecting slot, PAC adds pipe, curved baffle, spiral propeller, the collection
Mud groove arranges that the curved baffle is located at below the mud-collecting slot along coagulating basin surrounding, and the spiral propeller is located at coagulating basin
Bottom of pond, the PAC pipes are located at the top of the mud-collecting slot.
Further, the mud-collecting slot includes slot bottom aperture area and slot bottom enclosed area, and the slot bottom aperture area is located at sand setting
Pond overflow area opposite, for discharging the setting pot overflow mud collected, the slot bottom enclosed area is located at below setting pot overflow area
And adjacent pool wall, for forming pre-mix zone.
Further, the PAC adds pipe and arranges that, positioned at the mud-collecting slot top, bottom opens up along setting pot overflow area
Several apertures are used to implement multiple spot dosing, and the PAC added is pre-mixed with mud in the slot bottom enclosed area, then flows to institute
State slot bottom aperture area.
Further, the curved baffle axis is located at immediately below the mud-collecting slot slot bottom aperture area, collects mud described in face
Slot slot bottom axis, for rebound with PAC premixing from the mud-collecting slot aperture discharge the mud with certain flow rate,
Collision energy dissipating effect during by rebound realizes that mud is mixed with the reinforcing of PAC.
Further, the spiral propeller is four paddle blade structures, and the coagulating basin bottom of pond, edge are fixed on by steel bracket
Spoil disposal direction generates plug-flow effect, is mixed for forming PAC with the secondary hardening of mud.
The utility model advantage is：
（1）Coagulating basin transformation is carried out using the original overflow slurry collecting pond of setting pot, is not required to be separately provided coagulating basin, build
Make at low cost, speed is fast, and efficiency is transformed convenient for playing.
（2）PAC uses multiple spot injection mode, and preliminary mixing can be carried out in pre-mix zone and mud.
（3）Using in the mud dropping process with certain kinetic energy with baffle generate impact come carry out mud with
The reinforcing mixing of PAC, makes full use of the kinetic energy of mud in itself；
（4）Secondary hardening is carried out using the plug-flow effect of coagulating basin bottom spiral propeller with PAC to mud to mix, simultaneously
Adjust mud fluidised form.
