A kind of continuous multi-stage sedimentation tank of anti-mud residual
Technical field
The present invention relates to technical field of environment protection equipment, particularly to mudpan.
Background technology
Sludge water generally requires and carries out precipitation process, and the mud after precipitation is discharged from the bottom of sedimentation tank, the water after purification
Discharge from the top of sedimentation tank.Existing sedimentation tank is generally separately provided, and using natural sedimentation mode, the sedimentation time is longer,
The sedimentation effect being independently arranged sedimentation tank is not good.Applicant has applied for the special of entitled " a kind of continuous way mudpan " on the same day
Profit, solves the problems referred to above, but the deficiency of also presence is: the filtering holes of the filter press plate of employing are easily by sludge blockage, sedimentation tank
Inwall easily remain mud, need periodic cleaning and cleaning.
Content of the invention
The applicant is directed to the disadvantages mentioned above of prior art, is studied and improves, and provides a kind of company of anti-mud residual
Continuous multifeed clarifier, arranges multiple continuous sedimentation tanks, effectively improves sedimentation effect, and arrange rational structure, it is to avoid pressure
Filter plate blocking and the cleaning frequency extending sedimentation tank.
In order to solve the above problems, the present invention is using following scheme:
A kind of continuous multi-stage sedimentation tank of anti-mud residual, including the sedimentation tank of multiple continuous settings, adjacent sedimentation tank
Top there is connected entrance, the bottom of each sedimentation tank has sludge outlet;The center of described sedimentation tank is provided with guide rod, institute
State and the filter press plate with filtering holes is slidably fitted with guide rod, the top outer of sedimentation tank is provided with lifting motor, described lifting electricity
Machine is connected with filter press plate by drawstring, and lifting motor drives described filter press plate to slide up and down on described guide rod;Described sedimentation tank
Inside top the fixed plate consistent with described filter press plate profile is installed, described fixed plate is provided with and described filtration hole site
Corresponding inserted link;
The outer ring position of described filter press plate is provided with the water-guiding hole of inclination, and described water-guiding hole connects side face and the upper table of filter press plate
Face.
Improvement further as technique scheme:
Between from the sedimentation tank with mud import to the sedimentation tank with pure water inlet, the volume of described sedimentation tank is gradually
Reduce.
The upper surface outer ring position of described filter press plate is provided with the pressuring plate of outside bending, and pressuring plate is located at the upper of water-guiding hole
Outside end opening.
The method have technical effect that:
The present invention adopts multifeed clarifier, the continuous filtration to mud, and the filter press plate of the rate of filtration is accelerated in setting, shortens dirt
The filtration sedimentation time of mud, and improve sedimentation effect;It is additionally provided with the fixed plate with inserted link, for removing filter pressing in sedimentation tank
The mud of the filtering holes residual of plate, it is to avoid block and affect filter pressing effect;Setting water-guiding hole and pressuring plate on filter press plate, its lifting
When sedimentation tank inwall is rinsed, it is to avoid mud remain, greatly prolong the cleaning frequency of sedimentation tank.

Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described further.
As shown in Figure 1 and Figure 2, the continuous multi-stage sedimentation tank of the anti-mud residual of the present embodiment, including multiple continuous settings
Sedimentation tank 1, the top of adjacent sedimentation tank 1 has connected entrance 11, and the bottom of each sedimentation tank 1 has sludge outlet 2;Precipitation
The center in pond 1 is provided with guide rod 3, and guide rod 3 is slidably fitted with the filter press plate 4 with filtering holes 41, the top outer peace of sedimentation tank 1
Equipped with lifting motor 5, lifting motor 5 is connected with filter press plate 4 by drawstring 6, lifting motor 5 drive filter press plate 4 on the guide rod 3 on
Lower slider, filter press plate 4 pushes to the mud of lower section, accelerates settling velocity;The inside top of sedimentation tank 1 is provided with and filter pressing
The consistent fixed plate of plate 4 profile 9, fixed plate 9 is provided with inserted link 10 corresponding with filtering holes 41 position.When filter press plate 4 rises to
During top, inserted link 10 correspondence is plugged in filtering holes 41, by the mud extrusion of the residual in filtering holes 41, it is to avoid blocking.
The outer ring position of filter press plate 4 is provided with the water-guiding hole 42 of inclination, and water-guiding hole 42 connects side face and the upper table of filter press plate 4
Face, the upper surface outer ring position of filter press plate 4 is provided with the pressuring plate 12 of outside bending, and pressuring plate 12 is located at the upper end of water-guiding hole 42
Open outer side.When filter press plate 4 declines under self gravitation, sludge water is extruded by pressuring plate 12 to the inwall of sedimentation tank 1, thus right
Sedimentation tank inwall carries out supercharging and rinses, it is to avoid mud remains, when filter press plate 4 rises in the presence of lifting motor 5 upwards, dirty
Water enters from the upper end open of water-guiding hole 42, flows out from the side face opening of filter press plate 4, being obliquely installed, by sewage of water-guiding hole 42
Guiding rushes at the inwall of sedimentation tank 1, thus avoiding mud to remain.
The precipitation step by step to sludge water realized by continuous sedimentation tank 1, is reduces cost, the occupancy reducing space, from carrying
To the sedimentation tank 1 with pure water inlet 8, the volume of sedimentation tank 1 is gradually reduced the sedimentation tank 1 of mud import 7.
Sludge water enters first order sedimentation tank 1 from mud import 7, preliminary sedimentation after filter press plate 4 pressure;Tentatively heavy
The connected entrance 11 from top for the mixed liquor containing a small amount of mud behind shallow lake enters second level sedimentation tank 1, carries out second filter pressing;
Mixed liquor after secondary precipitation containing micro mud enters in third level sedimentation tank 1, carries out final filter pressing precipitation, last water purification
Discharge from pure water inlet 8;The sludge outlet 2 from sedimentation tank 1 bottom for the mud after precipitating every time is discharged.
Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not to this
Bright make any pro forma restriction, any those of ordinary skill in the art, if without departing from the carried skill of the present invention
In the range of art feature, using the Equivalent embodiments locally changed done by disclosed technology contents or modify, and
