Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment equipment technical field, concretely relates to a inclined plate type sedimentation device. BACKGROUND

[0002] The sedimentation device widely used in the field of water treatment mainly includes horizontal flow sedimentation tank, inclined pipe (plate) sedimentation tank. Among them, the inclined plate type sedimentation tank is widely applied due to its small land occupation, high processing efficiency, simple operation and maintenance and other advantages. The existing inclined plate type sedimentation device generally includes a sedimentation tank, and a plurality of parallel arranged inclined plates are arranged in the sedimentation tank. These inclined plates are usually arranged at a certain angle, so that when water flows, suspended particles are settled on the surface of the inclined plate under the action of gravity and slide along the inclined plate to the bottom of the sedimentation tank. This design can increase the settling area, thereby improving the solid-liquid separation efficiency.

[0003] However, the existing design of the inclined plate type sedimentation device has the following problems:

[0004] Large land occupation: Although the inclined plate design improves the settling efficiency, in order to treat large flow of water, the equipment itself still needs to occupy a larger space, which is a significant limitation in a limited space environment.

[0005] Prone to blockage: Due to the small spacing between the inclined plates, larger suspended particles or impurities are prone to block the gap between the inclined plates, causing poor water flow, thereby affecting the overall settling effect and processing efficiency.

[0006] Difficult to maintain: The internal structure of the inclined plate sedimentation device is complex, the number of inclined plates is large and densely arranged, which makes the cleaning and maintenance work difficult. Especially in the long-term operation process, the surface of the inclined plate is easy to attach sludge, bacteria and algae, which not only affects the equipment operation, but also reduces the water quality.

[0007] Limited settling efficiency: For small particles, the existing inclined plate type sedimentation device is difficult to achieve efficient separation and sedimentation due to the limitation of settling time and space, which affects the final treatment effect.

[0008] High operating energy consumption: In order to maintain the smooth flow of water through the inclined plate, the existing device often needs to be equipped with additional water pumps or other auxiliary equipment, which increases the overall energy consumption and operating cost.

[0009] Therefore, the prior art still needs to be improved and developed. UTILITY MODEL CONTENT
