Problems solved by technology

These types of sedimentation tanks generally have the problems of large floor area, long settling time, long construction period and high cost.
After research and analysis on the sedimentation mode of the existing sedimentation tank, it is found through experiments that the reason why the sedimentation efficiency cannot be improved is that the speed and direction of liquid movement conflict with the sedimentation speed and direction of the suspended solids, so that the suspended solids cannot coagulate quickly Flocculation and sedimentation affect the sedimentation efficiency

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings, in which a fully-sealed multi-layer spiral combined swash plate rotary sedimentation device. Mainly composed of: 1. Rotary drive 2. Fully enclosed device shell 3. Linkage device 4. Overflow weir 5. Outlet pipe 6. Multi-layer spiral combined inclined plate 7. Wedge grid cylinder 8. Sediment 9. Settlement ring joint 10. Water inlet pipe 11. Support legs 12. Conical sewage storage tank 13. Sewage pipe and other components.

[0018] The rotating device: the rotating driver 1 is connected with the linkage device 3 inside the shell 2 of the fully enclosed device, and drives the multi-layer spiral combination swash plate 6 and the wedge-shaped grid cylinder 7 to rotate slowly. Sewage enters the bottom of the wedge-shaped grid cylinder 7 from the water inlet pipe 10, and overflows from the gap on the cylinder to form between the multi-layer spiral composite inclined plates (the ...

Abstract

This invention discloses a fully-sealed multi-layer spiral combined inclined-plate rotating sedimentation apparatus and method thereof. The characteristics are as follow: the structure of wedge-grating cylinder functions to uniformly distribute water and change the water flow's direction. The whirling water, rising from the space between the composite inclined plates, accelerates collision among suspended solids between layers of inclined plates and makes them to quickly agglomerate into flocks which subside down the circular seam between the bottom of inclined plates and the inner wall of the sedimentation device. Advantages: overcomes the confliction of liquid moving speed and direction to suspended-solid sedimentation speed and direction. The suspended solids removal efficiency by this device within 4 min is equal to that of a traditional sedimentation tank by physical method in 120 min. This device is simple in structure design and easy in manufacturing and installing.

Description

technical field [0001] The present invention is a set of device and method for precipitating suspended solids in water treatment industry technical background [0002] At present, in the water treatment process, the sedimentation tanks that use physical methods to settle suspended solids include: horizontal flow sedimentation tanks, vertical flow sedimentation tanks, radial flow sedimentation tanks, and inclined plate inclined tube sedimentation tanks. These types of sedimentation tanks generally have the problems of large floor area, long settling time, long construction period and high cost. After research and analysis on the sedimentation mode of the existing sedimentation tank, it is found through experiments that the reason why the sedimentation efficiency cannot be improved is that the speed and direction of liquid movement conflict with the sedimentation speed and direction of the suspended solids, so that the suspended solids cannot coagulate quickly Flocculation an...
