Description
Technical field
The utility model relates to a kind of returned sludge concentration adjusting device of high dense settling pond and including this reflux
The high dense settling pond of sludge concentration regulating device.
Background technique
High dense settling pond is to be contacted with each other, inhaled with the impurity particle in coagulant and raw water using the body refuse in pond
Attached, precipitating, to reach the water purification building of mud-water separation purpose.
High dense settling pond is used for sludge reflux to flocculation basin in flocculation zone by the mud return line of sludge area lower part
The bigger more heavy wadding body of building, so as to more easy to remove in settling zone.The sludge concentration of returned sludge can not be adjusted, and
This concentration also can not Real_time quantitative detection, then, the sludge quantity for flowing back into flocculation zone can not just be adjusted, and then in flocculation zone
Mixed liquid concentration can not just be adjusted, so that wadding body size and compaction rate will be deteriorated, which results in the negative shadows of following three aspect
It rings:
On the one hand, wadding body settling velocity can decline, i.e. the rate decline of solid-liquid separation, cause at high dense settling pond
Reason rate is lower；
On the other hand, pond body is flowed out in the retention that tiny wadding body is easier to break through inclined tube with upward water flow, causes highly dense
Clarifying basin treatment effect is spent to be deteriorated；
Finally, the compaction rate of wadding body is poor, the wadding body sludge to be formed that precipitates is difficult to be compressed, the effect of sludge condensation
Also it can be deteriorated.Which results in sludge concentration decline, the content of water increases in sludge, needs when spoil disposal to be discharged more " dilute " dirty
Mud produces more secondary sewage, also brings impact for sludge treating system.Moreover, diluter sludge is back to wadding
Coagulation zone causes flocculation zone mixed liquid concentration and technique requirement is not achieved, forms vicious circle, be degrading treatment process.
Therefore, it is necessary to one kind can conditioning of mud return pipe open height, to adjust the scheme of returned sludge concentration.

Available more fully understand.In order to preferably show the relationship of each component in the accompanying drawings, attached drawing is not necessarily drawn to scale.It is attached
In figure:
Fig. 1 shows the returned sludge concentration adjusting device according to the present utility model being mounted in high dense settling pond,
In, the elevating lever of the returned sludge concentration adjusting device is in the first height and position.
Fig. 2 shows the returned sludge concentration adjusting device according to the present utility model being mounted in high dense settling pond,
In, the elevating lever of the returned sludge concentration adjusting device is in the second height and position.
Specific embodiment
It will be described in detail with reference to the accompanying drawings each embodiment according to the present utility model.Here it is to be noted that it in attached drawing
In, assign identical appended drawing reference to component part substantially with same or like structure and function, and close omitting
In their repeated description.Term " successively including A, B, C etc. " only indicates putting in order for included components A, B, C etc., and
A possibility that being not precluded between A and B and/or including other components between B and C.
The attached drawing of this specification is schematic diagram, aids in illustrating the design of the utility model, it is schematically indicated each section
Shape and its correlation.
Fig. 1 shows the returned sludge concentration adjusting device according to the present utility model being mounted in high dense settling pond,
In, the elevating lever of the returned sludge concentration adjusting device is in the first height and position.Fig. 2 shows be mounted in high dense settling pond
Returned sludge concentration adjusting device according to the present utility model, wherein at the elevating lever of the returned sludge concentration adjusting device
In the second height and position.
The returned sludge concentration adjusting device includes actuator 1, is installed to the driving unit 2 of high dense settling pond；It rises
Bar 3 is dropped, is mounted on actuator 1, can move up and down under the action of actuator 1；Jacking sleeve 6, one end is fixedly connected
To pre-buried reflux sludge tube 8, (advantageously, the diameter of jacking sleeve is greater than the diameter of reflux sludge tube, to cover dirty in reflux
Install outside mud pipe), the other end is connected to elevating lever 3, can with the movement of elevating lever 3 raising and lowering, thus change into
Enter the height of the returned sludge point of reflux sludge tube.Reflux sludge tube 8 is connect with mud discharging pipe 9, to discharge sludge.Scrape mud
Bridge 5 does circumferential movement under the action of driving unit 2, to sweep the sludge in high dense settling pond.
