Settling tank main body 2 is regular polygon or circle; Settlement plate 3 is round platform (or terrace with edge) faces that become 45~75 degree angles with horizontal plane that circumferentially are made of one group of platelet, and is low outer high in this round platform (or terrace with edge) face; Near having groove on the sedimentation face at cloth water drum place, i.e. mud-collecting slot, particle concentrates on and flows out settlement plate in this mud-collecting slot, the apopore on the position of mud-collecting slot and the cloth water drum staggers, adjacent about 8~10 centimetres of two-layer settlement plate spacings; The cloth water drum covers on the water inlet pipe, the apopore of cloth water drum from the distance of the sedimentation face of settlement plate more than 5 centimetres, 15~30 centimetres of the weather board length of apopore top; Radially the quantity of dividing plate is desirable 4,6,12,36, and concrete quantity depends on the intensity and the weight of the diameter and the settlement plate in pond; The bottom interior surface of mud-removing bucket is conical surface or faceted pebble, its inclination angle 45~60 degree.
Settlement plate, radially dividing plate can be with engineering plastics or steel plate.Settling tank main body, mud-removing bucket can be used brick mix structure, steel plate or engineering plastics.Surface of steel plate will carry out antirust processing.
In Fig. 1, settling tank main body, water leg are built routinely.The inclination angle of bottom surface, pond is 45~60 degree.As shown in Figure 2, in the present embodiment, every layer of settlement plate is made up of six platelets, in actual production, can determine the quantity of platelet as required, and purpose is convenient the construction.As shown in Figure 1, settlement plate is made up of three sections round table surface along generatrix direction, the part far away more from the cloth water drum is big more with the angle of horizontal plane, in the present embodiment, for sediment is flowed down smoothly, the angle of two round table surface in bottom and horizontal plane is respectively 45,50 degree, and the top round table surface is made 70 degree, press formings in advance for the guiding clear water.Certainly, in actual production, settlement plate can be by forming along two parts of generatrix direction or other many parts round platform or terrace with edge face.
As shown in Figure 3, except that minimum one deck settlement plate, each layer settlement plate all uses radially membrane support on lower floor's settlement plate.In the present embodiment, every platelet is with two membrane support (see figure 2)s radially.Radially dividing plate 10 not only rises and supports usedly, and the pond body is divided into some fan-shaped, helps precipitation, and large-scale sedimentation basin is having wind weather current to understand the influence of wind-engaging, and radially dividing plate 10 can weaken this influence.
As shown in Figure 4, radially connect with bolt 11 between dividing plate and the settlement plate, the settlement plate of minimum one deck is fixed by bolts on the inner bottom surface of settling tank main body.
In Fig. 5, on cloth water drum 4, have apopore 14, the weather board 12 of 30 centimeter length has been installed in apopore 14 tops, and the settlement plate bottom has mud-collecting slot 13, and mud-collecting slot 13 is between two apopores of lower floor.The mud-collecting slot on upper strata is between two apopores of lower floor, and the water that can avoid flowing out disturbs sludge settling.
In Fig. 6, be chosen in the mud scraper that the pond inner bottom part drives, at this moment, multiple layer settlement plate is fixed on the madial wall in pond.Certainly, the also suitable situation of not using mud scraper of this structure.
The operation principle of this sedimentation basin: sewage enters in the pond from the bottom water inlet pipe, under the guiding of the hole on the cloth water drum, enter the multiple layer settlement plate group at weather board, particles settling is on settlement plate in the process of climbing on sedimentation face, clear water rises at the pool side place and enters water leg, particle is regularly discharged outside the pond along sliding in the mud-removing bucket under the sedimentation face.
The utility model utilizes the shallow layer precipitating principle, advances the radial dimension that goes out sedimentation basin week in dwindling, thereby without mud-scraping mechanism, significant.Be exactly under the situation of using mud scraper, also can utilize multiple layer settlement plate, improve the disposal ability of sedimentation basin significantly, present technique also can be used for transforming existing settling tank.
Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
