Filtering and precipitation apparatus

Abstract

The invention provides a filtration and precipitation device. The cylinder of the filtration and precipitation device is divided into an inner cylinder and an outer cylinder. A water inlet pipe is fixed on the side wall of the outer cylinder of the filtration and precipitation device. The mouth of the water inlet pipe extends into the outer cylinder. The side wall of the inner cylinder is provided with a vertical groove inward, and the groove corresponds to the nozzle of the water inlet pipe, so that a gap is formed between the nozzle of the water inlet pipe and the groove to pass through; the height of the inner cylinder is lower than that of the water inlet pipe. mouth. The filter and sedimentation device of the present invention forms a gap between the groove of the inner cylinder and the mouth of the water inlet pipe. Without the need to reduce the diameter, it can be easily installed in the outer barrel of the sedimentation system, and also plays a guiding role to prevent bumps. The inner and outer cylinders prevent deformation; at the same time, after the inner cylinder of the filter and sedimentation device is placed, rotate the inner cylinder to ensure that the nozzle of the water inlet pipe extends to the upper part of the inner cylinder, and the incoming water does not flow out, which plays the role of filtering sediment.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a filtration and sedimentation device. Background technique [0002] The cylinder of the filtration and sedimentation device is divided into an inner cylinder and an outer cylinder. The outer cylinder of the filtration and sedimentation device is provided with a water inlet pipe. The final sediment can also be taken out with the inner cylinder for further treatment. [0003] In actual use, the inner cylinder should be placed inside the outer cylinder. When the inner cylinder is placed into the outer cylinder, pay attention to the positional relationship when placing it, and ensure that the nozzle of the water inlet pipe extends to the upper part of the inner cylinder, because the inlet on the outer cylinder The water pipe is fixed, so the water inlet pipe will inevitably interfere with the placement of the inner cylinder, and at the same time, it will also be misplaced, causing t...

Problems solved by technology

[0003] In actual use, the inner cylinder should be placed inside the outer cylinder. When the inner cylinder is placed into the outer cylinder, pay attention to the positional relationship when placing it, and ensure that the nozzle of the water inlet pipe extends to the upper part of the inner cylinder, because the inlet on the outer cylinder The water pipe is fixed, so the water inlet pipe will inevitably interfere with the placement of the inner cylinder, and at the same time, it will also be misplaced, causing the nozzle of the water inlet pipe to not extend to the upper part of the inner cylinder, so the inner cylinder for filtering sediment cannot receive incoming water and will not work.

[0004] The solution to the above misalignment is to greatly reduce the size of the inner cylinder to ensure the connection of the nozzle of the water inlet pipe, but at the expense of the volume of the inner cylinder, the frequency of cleaning the inner cylinder will be too high
