Efficient and safe sedimentation tank with high controllability

Abstract

The invention relates to an efficient, safe and highly controllable sedimentation tank, which includes a body, a rectifying plate, an adjustment mechanism and a working power supply module. The adjustment mechanism includes a first support plate, a first motor, a first worm, a first worm wheel, a second The worm and the adjustment assembly, the adjustment assembly includes the rotating shaft, the second worm wheel and the swash plate, the high-efficiency, safe and highly controllable sedimentation tank is an advection type swash plate settling tank, the adjustment mechanism can precisely control the inclination angle of the swash plate group, so as to achieve a higher Accurately control the sedimentation efficiency of the sedimentation tank. In addition, the working power module can remove the sludge deposited on the sloping plate, prevent the sludge accumulation from affecting the sedimentation efficiency, and ensure that the sedimentation tank can be used stably for a long time. In the working power circuit, the use field The high power gain of the effect tube VT2 can simplify the circuit, and at the same time can output a large enough current, which improves the practicability of the working power supply circuit and the practicability of the adopted device.

Description

technical field [0001] The invention relates to the field of sedimentation tanks, in particular to a high-efficiency, safe and highly controllable sedimentation tank. 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 principl...

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 tanks, the sloping plates are often blocked by sludge, which seriously affects the sedimentation efficiency. The output power of the working power circuit is insufficient, which affects the working efficiency of the device and reduces its reliability.
