The further advantage, target and feature of the utility model will be partially reflected by the following instructions, and part will also pass through Research and practice to the utility model and be understood by the person skilled in the art.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the top view of the utility model.

Specific embodiment

The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art referring to explanation Book text can be implemented accordingly.

It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more The presence or addition of a other elements or combinations thereof.

As shown in Figure 1, 2, the utility model provides sedimentation basin, comprising:

Pond body 1, is the cylindrical-shaped structure of upper end opening, and 1 top edge of pond body forms several overflow ports；

Sewage inlet pipe 2, is vertically set on 1 bottom centre of pond body, and 2 upper end of sewage inlet pipe forms wastewater inlet 21, for being passed through sewage, 2 side wall of sewage inlet pipe is formed with multiple outlets of sewer, is respectively connected with one on each outlet of sewer Diversion pipe 3, the free end of the diversion pipe 3 slightly toward 1 top of pond body, and the axis of the diversion pipe 3 with it is described The axis of sewage inlet pipe 2 be in 70~75 ° of angles, diversion pipe 3 slightly upward, convenient for sewage dispersion and convenient for sedimentation；

Be up-small and down-big round-like structure every mud shell body 4, it is described to be open every 4 upper and lower ends of mud shell body, it is described every The lower edge of mud shell body 4 and the inner wall of the pond body 1 are fixed, and fixed bit is setting in several overflow ports lower sections, institute State every being distributed with fish scale hole 41 on the side wall of mud shell body 4, the opening of the fish scale hole 41 towards 1 center of pond body, it is described every The angle of rotary table median generatrix and bottom surface where mud shell body 4 is 30 °, and upper bottom surface radius is the 3/4 of bottom radius surface, i.e., The upper bottom surface radius of rotary table is the 3/4 of bottom of pond radius；

It is multiple every mud cover 5, it is the multiple corresponding with the free end position of each diversion pipe 3 respectively every mud cover 5, it is described every mud Cover 5 includes support rod 52 and cover 51, and the support rod 52 is vertically fixed on 1 bottom of pond body, and the support rod 52 is close The position of upper end is provided with screw thread, and the cover 51 is in up-small and down-big umbrella-shaped structure, and 51 inside top of cover is equipped with spiral shell Hole, the cover 51 are threadedly coupled by screw hole with the support rod 52, and cross filter opening is distributed on 51 side wall of cover.

In the above-mentioned technical solutions, pond body 1 can be made of concrete, be hollow cylindrical, and the upper end-face edge of pond body 1 is set Be equipped with overflow port, pass through the obtained water purification of precipitation process for flowing out, be provided in the middle part of pond body 1 sewage for being passed through sewage into Pipe 2 adjusts the flow velocity that settling velocity only needs to adjust sewage inlet pipe 2, easy to adjust.Sewage inlet pipe 2 can also be by coagulation Soil is made, and sewage enters from 2 upper end of sewage inlet pipe, and sewage can be pumped into or flow under gravity, sewage inlet pipe 2 Outlet of sewer is arranged in side wall, and sewage enters in pond body 1 from outlet of sewer.Diversion pipe 3 is connected at outlet of sewer, diversion pipe 3 will be dirty Water is guided in pond body 1, avoids the movement that sewage is unordered.Setting is every mud cover 5 above the free end of diversion pipe 3, every mud cover 5 in umbrella Shape flows out sewage in diversion pipe 3, and sewage is spread by the blocking every mud cover 5 along cover 51 around, rather than upwards Movement, slows down the impact force of sewage every mud cover 5, avoids impact from having already passed through the water purification of the top clean water area of precipitating, every mud cover 5 Bulky grain suspended substance sedimentation is also assisted, sinking speed is improved.Every the setting of mud shell body 4 in 1 inner wall of pond body, there is spy every mud shell body 4 Fixed size and angle, when newly entering guidance of the sewage by cover 51 and further being moved to 1 surrounding of pond body, further by every The blocking of mud shell body 4, avoids newly entering sewage and impacts to the water purification flowed out from overflow port, also further promotes newly to enter sewage Sedimentation.Fish scale hole 41 and cross filter opening all play the filtration of sewage, and cross filter opening is also separated sewage and draws Stream, avoids sewage from excessively concentrating and is unfavorable for settling, fish scale hole 41 also acts as the effect changed the direction of a stream of water, so that from every mud shell 4 lower part of body rises the trend moved in the middle part of the oriented pond body 1 of sewage come, settles sewage further at middle part, improves precipitating effect Fruit.It is cleaned every mud cover 5 and after mud shell body 4 can be dismantled out of pond body 1, fish scale hole 41 and the cross filter opening side of also acting as Just the effect rinsed.As can be seen that the technical program can be avoided the water purification generation interference for newly entering sewage to clean water area, and draw Lead sewage more regularly from centre spread and settle around, Equalsettlement, and newly enter sewage on top water purification influence compared with Small and every mud cover 5 and every the barrier effect of mud shell body 4, sinking speed is fast, and every mud cover 5 and every mud shell body 4 it is detachable It cleans and replaces afterwards, reduce cleaning difficulty.

In another technical solution, the sedimentation basin, 1 bottom of the pond body centre is high, surrounding is low.Here, bottom Also guidance sewage is spread around by centre, and sewage is avoided directly to impact clean water area.

In another technical solution, the sedimentation basin, the free end of the diversion pipe 3 and 1 bottom of pond body Spacing is not more than 20 centimetres.Here, 20 centimetres are preferred distance, can reduce the interference for newly entering sewage as far as possible.

In another technical solution, the sedimentation basin, under the free end of the diversion pipe 3 is located at the cover 51 just The height of side, the support rod 52 is not more than 100 centimetres, and projection radius of the cover 51 in 1 bottom of pond body is not less than 150 centimetres.Here there is provided the preferred height and projected area of cover 51, it can preferably guide and newly enter sewage, promote newly to enter Sewage relatively slowly rises.

In another technical solution, the sedimentation basin, 1 bottom margin of pond body is provided with multiple mud discharging mouths, institute It states 1 bottom of pond body and is formed with multiple spoil disposal ditches, the spoil disposal ditch is connected to the mud discharging mouth.Here there is provided the structure of spoil disposal, It is further provided convenience for cleaning sedimentation basin, spoil disposal ditch convenient for rinsing, and guides the dirt of generation along the inclined direction of bottom of pond Mud is deposited to mud discharging mouth.

In another technical solution, the sedimentation basin, 1 bottom of pond body and internal side wall are coated with polytetrafluoroethylene (PTFE) Coating.Here, polytetrafluorethylecoatings coatings reduce the viscosity of pond body 1 bottom and side wall and sludge, promote sludge heavy to mud discharging mouth Product, and further facilitate flushing.

Number of devices and treatment scale described herein are the explanations for simplifying the utility model.To the utility model The application of sedimentation basin, modifications and variations will be readily apparent to persons skilled in the art.

It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art, Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality It is not limited to specific details and legend shown and described herein with novel.
