Abstract
The utility model discloses a kind of settling tank central draft tube structure, the lower end of water conservancy diversion is connected with the unhurried current cover of bell mouth shape, intersects in unhurried current cover and is equipped with supporting plate, supporting plate is provided centrally with center ring.The utility model is by changing original guide shell bottom structure form, only carrying out simple assembled welding to existing vertical-type guide shell can be realized, structure is simple, construction is easy, effectively eliminate direct impact of the water flow to settling tank bottom, the phenomenon that preventing mud granule to float, reducing mud granule outlet.
Description
Technical field
The utility model relates to sewage disposal device, in particular to a kind of settling tank central draft tube structure.
Background technique
Sedimentation basin uses in all kinds of sewage treatment process more as equipment for separating liquid from solid, and extracts out with mud scraper, mud
The equipment such as pump are used cooperatively, and achieve the purpose that mud-water separation.In the treatment process of coked waste water, biochemical treatment from front end,
To subsequent depth decolorization, require using to precipitating pool equipment.
In coked waste water advanced treatment process, sewage flows into sedimentation basin after dosing-aerating oxidation-flocculation, leads to
It crosses guide shell to flow into pond from top to bottom, be uniformly distributed.Sedimentation basin used in coked waste water advanced treatment process, center are led
Flow cartridge is mostly straight barrel type structure, when entering guide shell water and increasing, it may appear that the case where water flow disorder, guide shell exit
Water, which can carry the mud granule in water secretly, to float, while water flow also will drive mud granule along the periphery of guide shell, float up to
Sedimentation basin clear water zone surface causes have the case where mud granule floating at the centre of surface of sedimentation basin clear water zone, influences clear water zone
Perception, while may cause a small amount of outlet of mud granule.
Utility model content
It is the structure by changing central draft tube that the utility model, which will solve technical problem, eliminates original water conservancy diversion barrel structure
Caused by sedimentation basin clear water zone mud granule rising phenomenon, prevent the outlet of mud granule.
Above-mentioned purpose is implemented with the following technical solutions in the utility model.A kind of settling tank central draft tube structure, water conservancy diversion
The lower end of cylinder is connected with the unhurried current cover of bell mouth shape, intersects in unhurried current cover and is equipped with supporting plate, supporting plate is provided centrally with center ring.
Further, the plane of the supporting plate is 5 ° ~ 85 ° with the angle of vertical cylinder axis.
Further, the supporting plate is in the shape of a spiral.
Further, the center ring is circular configuration.
Further, the section of the center ring is round, flat or triangle.
Further, when the section of the center ring is flat or triangle, ring body is in the shape of a spiral.
The utility model only carries out existing vertical-type guide shell by changing original guide shell bottom structure form
Simple assembled welding can be realized, and structure is simple, and construction is easy, and effectively eliminate direct punching of the water flow to settling tank bottom
It hits, it is therefore prevented that the phenomenon that mud granule floats, and reduces mud granule outlet.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the bottom view of Fig. 1；
Fig. 3 is center ring 2 and 3 assembled state schematic diagram of supporting plate in the utility model.
In figure: 1. guide shells, 2. center rings, 3. supporting plates, 4. unhurried current covers.
Specific embodiment
Below in conjunction with drawings and examples, the utility model is described in further detail.Referring to Fig. 1 and Fig. 3, a kind of settling tank
Central draft tube structure, the lower end of guide shell 1 are connected with the unhurried current cover 4 of bell mouth shape, intersect in unhurried current cover 4 and be equipped with supporting plate 3,
Supporting plate 3 is provided centrally with center ring 2, and center ring 2 is circular configuration.The plane of supporting plate 3 is 5 ° with the angle of vertical 1 axis of cylinder
~85°.Supporting plate 3 is in the shape of a spiral.The section of center ring 2 is round, flat or triangle.The section of center ring 2 is flat or triangle
When shape, ring body is in the shape of a spiral.
Embodiment: the utility model installs the unhurried current cover 4 of biggish bell mouth shape in vertical 1 lower part of guide shell, unhurried current
The diameter of the horn mouth maximum of cover 4 is two times of 1 diameter of guide shell, can substantially reduce the flow velocity into water.According to flow velocity with
The relationship of caliber, the water flow velocity of horn mouth the widest part of unhurried current cover 4 are only 1/4 at guide shell 1, can greatly reduce water flow pair
The impact of bottom is equipped with circular center ring 2 by supporting plate 3 at 4 centers of unhurried current cover, the interference by supporting plate 3 to water flow
Effect destroys the issuable disorder of water flow and disturbs situation, while the bell-mouthed side wall of cover 4 that flows slowly can stop water flow to drive dirt
Mud floats, and sludge is pushed back bottom of pond.Center ring 2 and supporting plate 3 in the utility model use its section of band steel profile for rectangle
When, sped structure can be used, can preferably interfere or water flow is stopped directly to impact precipitating bottom of pond portion and stirred sludge.Separately
Outside, the plane of supporting plate 3 is 35 ° with the angle of vertical 1 axis of cylinder, can make water flow generate rotation, reduce Mud up-floating dynamics and
Speed is conducive to mud granule and precipitates in bottom section.
