Description

Technical Field

[0001] The utility model relates to the technical field of sewage pipe filtration, in particular to a sewage pipe with a filtration structure. Background Art

[0002] The pollutants contained in domestic sewage are mainly organic matter and a large number of pathogenic microorganisms. In the process of treating domestic sewage, in order to simplify the subsequent treatment procedures, it is necessary to add a filtering mechanism to the sewage pipe. When filtering sewage, existing sewage pipes with filtering functions often install sewage filter plates. The existing sewage pipes mainly weld the filter plates inside the sewage pipes. Since sewage contains a certain amount of solid impurities, if they are not cleaned regularly, the impurities will clog the filter plates, thereby affecting the sewage filtration effect.

[0003] Patent announcement number CN215211425U describes a sewage pipe with a filtering function, including a pipe body, both ends of the pipe body are provided with mounting grooves, a filter plate is slidably arranged in the mounting grooves, the outer circular surface of the filter plate is fixed with a plurality of connecting ears distributed in an array, the outer ends of the connecting ears are fixed with fixing clips, and the fixing clips are clamped on the pipe mouth of the pipe body. The filter plate is installed in the sewage pipe by sliding the filter plate connected with the fixing clip into the mounting groove. When removing and replacing the filter plate, the filter plate is taken out of the pipe body by grabbing the fixing clip, thereby disassembling and assembling the filter plate.

[0004] However, this device has some shortcomings when used. Although it solves the problem that the filter plates in the sewage pipe cannot be replaced regularly, the filter plates in the sewage pipe can only be set at both ends of the sewage pipe. During long-distance sewage treatment, the sewage pipe cannot be spliced ​​with other pipes.

[0005] Based on this, a sewage pipe with a filtering structure is now provided to eliminate the disadvantages of the existing device. Utility Model Content
