Convenient-to-clean drainage pipeline for water storage tank

Abstract

The invention discloses a convenient-to-clean drainage pipeline for a water storage tank, and belongs to the technical field of drainage facilities. The device mainly comprises a water storage pond, a drainage pipe arranged at the bottom of the water storage pond, an inner pipe unit located in the drainage pipe and a filtering unit located in the inner pipe unit, the drainage pipe comprises a cylindrical base, a cylindrical pipe wall is fixedly installed on the upper section of the base, and a limiting block is arranged on the inner wall of the upper end of the pipe wall; the inner pipe unit comprises a lower pipe and an upper pipe located at the upper end of the lower pipe, a first limiting groove corresponding to the limiting block is formed in the outer wall of the lower pipe, a second limiting groove corresponding to the limiting block is formed in the outer wall of the upper pipe, and the lower pipe is rotationally connected with the upper pipe; the lower pipe and the upper pipe are both connected with the inner wall of the pipe wall in a sliding mode, and the number of the limiting blocks, the number of the first limiting grooves and the number of the second limiting grooves are not less than one. According to the drainage pipeline for the water storage tank, impurities can be prevented from entering the pipeline when the filter screen is cleaned.

Description

technical field [0001] The invention relates to the technical field of drainage facilities, in particular to a drainage pipe for a water storage tank that is convenient for cleaning. Background technique [0002] In all aspects of water treatment, it is often necessary to use a water storage tank to centrally treat a large amount of water. During this process, sediments and impurities are often generated. For some easy-to-clean impurities, it is usually carried out by the filter screen at the drain outlet. Strain out and clean it up after draining is complete. [0003] In the actual process, the filter will be blocked due to the reasons such as the employees do not clean it carefully or in time, resulting in a sharp drop in the drainage speed. At this time, the filter needs to be taken out for cleaning. However, in the conventional design of drainage pipes, The valve in the pipeline is directly taken out of the filter screen. At this time, there are still some pipelines con...

Problems solved by technology

[0003] However, in the actual process, the filter screen will be blocked due to the lack of care or timely cleaning by employees, resulting in a sharp drop in drainage speed. At this time, the filter screen needs to be taken out for cleaning. However, in the conventional drainage pipeline design, The valve in the pipeline is directly taken out of the filter screen. At this time, part of the pipeline is still connected to the water storage tank. After the filter screen is lost, the impurities in the water will enter its interior, and after the pipeline is opened again, it will enter the follow-up device by mistake, and it will be easily damaged over time.
