Automatic washing and precipitating pool

Abstract

The invention discloses an automatic washing and precipitating pool which comprises a pool body, wherein one end of the bottom of the pool body is connected and communicated with a dirt flushing pipeline, while the other end of the pool bottom is connected and communicated with a blow-down pipeline; the pool bottom is a slant pool bottom and provided with a grating plate; and shutter type watertight membrane cloth is horizontally arranged on the grating plate. In the invention, the bottom of the precipitating pool is built to be uniformly inclined towards the blow-down port for a certain gradient, and meanwhile, the bottom of the pool body is provided with the grating plate, and the shutter type watertight membrane cloth is horizontally arranged on the grating plate. During precipitating, the shutter type watertight membrane cloth is rolled up, so that dirt precipitates at the pool bottom; during flushing, the shutter type watertight membrane cloth is unfolded and used for dividing the precipitating pool into an upper area and a lower area, wherein the area above the grating plate is a clean water area, and the area below the grating plate is a sewage area, so that sewages below the grating plate cannot be mixed with clean water above the grating plate during flushing, thereby guaranteeing that water on the upper part of the precipitating pool cannot be polluted during flushing.

Description

technical field [0001] The invention belongs to a device in the process of circulating water treatment, in particular to a new type of sedimentation tank capable of automatic cleaning. Background technique [0002] In today's industrial circulating water treatment process, all of them are equipped with a sedimentation tank unit. In industrial circulating water, the sedimentation tank not only plays the role of settling particles and dust in the water, removing impurities and cleaning water, but also plays a role of heat exchange. But existing settling tank all is to adopt the settling tank of unified flat bottom formula (or one inclined flat bottom formula), and when sedimentation impurity reaches a certain degree, adopts to put water clean, manually goes to the bottom of settling tank to remove silt impurity. [0003] Such a sedimentation tank has the following problems: 1. Since the water in the sedimentation tank is dynamic, the sediment in this flat-bottomed sedimentatio...

AI Technical Summary

Problems solved by technology

[0003] Such a sedimentation tank has the following problems: 1. Since the water in the sedimentation tank is dynamic, the sediment in this flat-bottomed sedimentation tank cannot settle smoothly at the bottom, so that part of the sediment is dissolved into the water under the dynamic water movement Enter the next link, thereby reducing the role of the sedimentation tank

2. In the flat-bottomed sedimentation tank, every once in a while, when the sedimentation impurities reach a certain level, the water should be drained, and the sludge and impurities should be removed manually at the bottom of the sedimentation tank. This will affect production, especially for large-scale enterprises, which is inconvenient for modern management.
