PVC sewage drain pipe

Abstract

The invention discloses a PVC sewage drain pipe. The PVC sewage drain pipe comprises a main pipe body. The middle of the main pipe body is provided with a main drainage channel. The two sides of the main pipe body are each provided with one or more mounting holes communicating with the main drainage channel. Every two adjacent mounting holes are arranged in a slanting mode. Two delivery assistantpipes are inserted into the every two mounting holes located on the left and right sides. The external extension ends of the every two delivery assistant pipes are each provided with a U-shaped connecting section. A sealing sheet is arranged at the end of a water inlet of the top of the main pipe body. The middle of the sealing sheet is provided with an auxiliary water inlet. The auxiliary water inlet communicates with the delivery assistant pipes. The PVC sewage drain pipe delivers sewage into two cavities. The sewage with solid particles is delivered through the delivery assistant pipes. Thesewage without solid particles is delivered through the main pipe body. Under the impact action of water flow, the sewage with the solid particles can smoothly flow in the delivery assistant pipes correspondingly, and the pipeline is protected against overall blockage.

Description

Technical field [0001] The invention relates to the field of sewage transmission, in particular to a PVC sewage drainage pipe. Background technique [0002] When sewage is discharged, use a special sewage drainage pipe for drainage. The sewage contains a large amount of solid shells. The output end of the sewage drainage pipe will be connected to the sewage treatment center, which will filter out the solid particles in the sewage, and then conduct water treatment. It takes a long time to separate the solid particles and sewage, which brings inconvenience to the later water treatment. Furthermore, when the sewage is discharged, the solid particles in the sewage will continue to accumulate and cause the drainage pipe to be blocked. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a PVC sewage drainage pipe, which can separate sewage and solid particles first, so that the sewage can be directly recycled into the sewage treatm...
