Abstract
The utility model discloses a vertical-flow sewage sedimentation tank belonging to sewage disposal facility. The vertical-flow sewage sedimentation tank comprises a shell (3) and a base pipe (4), wherein the shell is in cylinder shape at the upper part and is in cone tubular shape at the lower part; the base pipe (4) is arranged at the centre of the shell (3) and is communicated with a water inlet pipe. The vertical-flow sewage sedimentation tank is characterized in that the lower opening of the base pipe (4) is provided with at least three blades (5) which are in spiral distribution. Through a simple structure, the movement path through which the sewage flows from the base pipe to the sewage sedimentation tank is lengthened; the settling time of suspended matter in sewage is increased, so that the settling effect of the suspended matter in sewage is improved and the water treatment effect is improved.
Description
Technical field
The utility model relates to the improvement of a kind of sewage disposal device, particularly a kind of vertical flow style sewage sedimentation tank.
Background technology
In the sewage treatment process, sedimentation basin is divided into flat flow, radial-flow and vertical-flow three kinds by water (flow) direction, and wherein vertical sedimentation basin is because floor space is little, and spoil disposal is easy, and sludge settling efficient height is usually used in small-sized sewage disposal.Vertical flow style sewage sedimentation tank mostly is cylindrical shape greatly, sewage is entered from top to bottom by the central tube that is located at the center, pond, from the lower end of central tube through on the cross section that evenly is distributed in the pond behind the reflecting plate of taper lentamente and slowly rise, suspended substance sedimentation enters in the heavy bucket of pond base cone shape, and primary water goes out along the peripheral overflow weir flow all around from the pond.The one side in pond is established discharge pipeline by pool wall and by hydrostatic pressing mud is regularly discharged.Existing vertical flow style sewage sedimentation tank, because the lower port and the taper reflecting plate close together of central tube, when sewage entered in the pond from top to bottom by central tube, the route of water movement was shorter, caused in the sewage suspension sedimentation effect bad, influenced the water treatment effect.
The utility model content
At the above-mentioned defective that exists in the prior art, the utility model provides a kind of sedimentation effect good vertical flow style sewage sedimentation tank.
The utility model is achieved by the following technical solution: a kind of vertical flow style sewage sedimentation tank, comprise that top is cylindric, the bottom housing for the awl tubular, be located at the central tube that the housing center is communicated with water inlet pipe, it is characterized in that: the lower port of described central tube is provided with at least three blades of shape distribution in the shape of a spiral.
The utility model is provided with the blade that shape in the shape of a spiral distributes by the lower port at the central tube of sedimentation basin, make sewage when entering in the pond from top to bottom by central tube, the effect of the blade of process lower port, current are disperseed towards periphery, the moving line of current increases, increase the sedimentation time of suspension in the sewage, helped improving the sedimentation effect of suspension in the water.
In order to improve sedimentation effect and to consider processing of leaves technology, the blade shape in the utility model can adopt the right-angled trapezium shape.When blade adopted the right-angled trapezium shape, the narrow end of blade was connected with the lower port of central tube, and its wide end stretches out outside the central tube and is connected with the reflection cone that is located at the central tube below.
The beneficial effects of the utility model are: the utility model is by simple structural design, make the moving line when sewage enters in the pond by central tube increase, increase the sedimentation time of suspension in the sewage, improved the sedimentation effect of suspension in the water, improved the water treatment effect.

Fig. 2 is that A among Fig. 1 is to view;
Fig. 3 is the schematic diagram of the blade of right-angled trapezium shape;
Among the figure, 1, water collector, 2, water inlet pipe, 3, housing, 4, central tube, 5, blade, 6, reflection cone, 7, discharge pipeline, 8, mud discharging mouth.
The specific embodiment
Also in conjunction with the accompanying drawings the utility model is further described below by non-limiting embodiment:
As shown in drawings, shown in the present embodiment is a kind of vertical flow style sewage sedimentation tank, and it comprises housing 3, central tube 4, water inlet pipe 2, discharge pipeline 7, water collector 1.The top of housing 3 is cylindric, and the bottom is the awl tubular structure, and water collector 1 is located at the top of housing 3.Central tube 4 is located at the center of housing 3, and along its axial setting, the lower end of central tube 4 is a bell mouth shape, and its lower port is provided with the blade 5 that a plurality of shapes in the shape of a spiral distribute.Below central tube 4, be provided with reflection cone 6.Blade 5 one ends can be welded on the tube wall of lower end of central tube 4 or connect by other connected mode, and the other end is connected with reflection cone 6.Water inlet pipe 2 is communicated with the top of central tube 4.Discharge pipeline 7 is along the housing wall setting of housing 3, and the bottom of the awl tube of housing 3 is stretched in its lower end, and mud discharging mouth 8 is established on its top.
The quantity of the blade 5 in the present embodiment can be adjusted according to the design needs, can be more than 3 or three, and the quantity of blade 5 is 6 in the present embodiment.The shape of blade 5 can adopt the different shape that can reach the water outlet effect, considers the simplicity of water outlet effect and structural design, and the shape of blade 5 can adopt the right-angled trapezium shape.When blade adopted the right-angled trapezium shape, the narrow end of blade was connected with the lower port of central tube, and its wide end stretches out outside the central tube and is connected with reflection cone 6.
The course of work of the present utility model is: sewage enters central tube 4 from water inlet pipe 2, and it is from top to bottom mobile along central tube 4, after blade 5 effects through central tube 4 lower ends, through evenly distributing sewage in the pond after, the reflection cone under the central tube 6 slowly rises again along the whole cross-section of river, suspended substance sedimentation enters at the bottom of the pond to be stored up in the conically shaped, and primary water is gone into water collector 1 along the peripheral overflow weir flow around from the pond and discharged.Being deposited at the bottom of the pond mud in the conically shaped regularly discharges mud by discharge pipeline 7 by hydrostatic pressing
Other parts of present embodiment adopt prior art, do not repeat them here.
The foregoing description only is used for explanation of the present utility model, is not to its restriction, and those skilled in the art also can make a change on this basis.
