Settling pond with high controllability

Abstract

The invention relates to a settling pond with high controllability. The settling pond comprises a main body, a rectifying plate, an adjusting mechanism and a cleaning mechanism, wherein the adjusting mechanism comprises a first supporting plate, a first motor, a first screw, a first worm wheel, a first worm, a second worm and an adjusting assembly; the adjusting assembly comprises a rotary shaft, a second worm wheel and an inclined plate; the cleaning mechanism comprises a second supporting plate, a second motor, a third worm, a third worm wheel, a fourth worm and an adjusting assembly; the cleaning assembly comprises a lead screw, a fourth worm wheel and a cleaning unit; and the cleaning unit comprises a slide block and a brush. The settling pond with high controllability is a flat flow type inclined plate settling pond, and the adjusting mechanism can precisely control the inclination angel of the inclined plate group, so that the settling efficiency of the settling pond can be relatively precisely controlled. In addition, the cleaning mechanism can eliminate sludge deposited on the inclined plate to prevent the sludge from being piled to affect the settling efficiency, so that the settling pond can be stably used for a long time.

Description

technical field [0001] The invention relates to the field of sedimentation tanks, in particular to a sedimentation tank with high controllability. Background technique [0002] Sedimentation tank is a structure that uses sedimentation to remove suspended solids in water. Sedimentation tanks are widely used in wastewater treatment. It has many types, which can be divided into three types: advection type, vertical flow type and radial flow type according to the direction of water flow in the pool. [0003] There is a very shallow sedimentation tank between every two parallel inclined plates in the inclined plate sedimentation tank. The treated water (or waste water) and the settled sludge move and separate from each other in the shallow sedimentation layer. According to their mutual movement direction, it can be divided into three different separation methods: co-flow, counter-flow and lateral flow. The inclined plate sedimentation tank uses the principle of "shallow sedime...

AI Technical Summary

Problems solved by technology

[0005] There are many deficiencies in the existing sloping plate sedimentation tank. Under the condition that other conditions remain unchanged, since the sedimentation efficiency of the sloping plate is directly proportional to the projected area of ​​the sloping plate on the bottom surface, the sloping plate of the existing sloping plate sedimentation tank Most of them are fixed, or some can shake, but it is useless to precisely control the angle of the inclined plate, so that the sedimentation efficiency of the sedimentation tank cannot be precisely controlled

In addition, in the existing sloping plate sedimentation tank, the gap between the sloping plates is often blocked by sludge, which seriously affects the sedimentation efficiency.
