Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy projects, and in particular relates to a filtering pipeline for water conservancy projects. Background Art

[0002] Patent No. CN213823748U discloses a filter pipe for water conservancy projects, which relates to the technical field of water conservancy projects. The filter pipe for water conservancy projects includes a water inlet pipe, a filter pipe and a cleaning pipe. One end of the water inlet pipe is fixedly connected to the filter pipe, the side of the filter pipe is fixedly connected to the cleaning pipe, the inner side of the baffle is fixedly connected to the filter screen, the side of the filter screen is connected to the rotating shaft, the side of the rotating drum is fixedly connected to the fan blade, and the side of the rotating drum is fixedly connected to the cleaning rod. The filter pipe for water conservancy projects uses the sudden increase in the pipe diameter to reduce the water flow rate. The filter screen is set in the filter pipe to intercept impurities through the filter screen. The filter screen also plays a role in reducing the water flow rate, so that the water has a chance to settle in the filter pipe and tilt. The obliquely arranged fan blades rotate, and during the rotation process, the sediment on the inner wall of the filter tube is scraped off. At the same time, the cleaning rod fixedly connected to the side of the drum rotates synchronously with the drum to scrape off impurities on the side of the filter screen to prevent the filter screen from being blocked. In the above device, the filter holes of the filter screen are continuously cleaned by arranging a cleaning mechanism in the pipeline. Each time the impurities are cleaned, they still fall into the inside of the pipeline. Moreover, the filter screen is generally arranged inside the pipeline. The disassembly and assembly of the filter screen is not very convenient, and the middle section of the pipeline cannot be removed separately to replace the filter screen, which reduces flexibility. For this reason, we propose a filter pipe for water conservancy projects. Utility Model Content
