Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water treatment, in particular to a drainage pipe with a filtering and impurity removal structure. Background Art
[0002] Normally, city tap water undergoes multiple stages of treatment before being supplied to users, including filtration and disinfection, to ensure the safety and cleanliness of the water quality. These treatment steps greatly reduce the possibility of sand and gravel being carried in the water flow. Although under normal circumstances, the water flow into the household water pipe is unlikely to contain sand and gravel, it may still happen in some special circumstances. During pipeline construction or maintenance, if the impurities and residues in the pipe are not thoroughly cleaned, the water flow may carry impurities such as sand and gravel. If there are geological changes in the water source or the water quality deteriorates, the water flow may carry more impurities and pollutants. Over time, the water supply pipe may wear and break due to aging, thereby increasing the risk of impurity infiltration. Ordinary water supply pipes (drainage pipes) do not have the function of filtering impurities, causing impurities to block the inlet and outlet of subsequent water-using equipment. Currently, a pre-filter is used to filter the water entering the household. The pre-filter is expensive and the filter element needs to be replaced regularly, and the cost of use is high.

[0005] Furthermore, the filter screen includes a stainless steel frame and a filter screen, and a slope is provided on the top of the stainless steel frame.
[0006] Furthermore, a top slot block is fixedly provided on the top of the inner wall of the square shell, and the top slot block is provided with an inclined slot that matches the top of the stainless steel frame.
[0007] Furthermore, a bevel hole is opened at the bottom of the square shell, and a stopper A and a stopper B are fixedly provided on the hole wall surface of the bevel hole, and the bottom of the stainless steel frame is clamped between the stopper A and the stopper B.
[0008] Furthermore, guide slopes are provided on both sides of the stopper A, and the vertical cross-section of the stopper A is in the shape of an isosceles trapezoid.
