Internal rapid drainage method for building

Abstract

The invention discloses an internal rapid drainage method for a building. The method comprises the following steps that S1, a shell is fixedly connected with a downpipe, the downpipe communicates with a rotating cylinder in the shell, and the bottom of the shell is connected with a drainage pipe; S2, a servo motor is started, and the servo motor drives a worm wheel and a worm to rotate; S3, the worm indirectly drives a spiral cutting piece to rotate in the rotating cylinder, and large impurities are cut up; and S4, the worm wheel drives an air pressure mechanism to complete pressurization on the downpipe, and the air pressure is increased to flush out the cut impurities from the rotating cylinder and discharge the impurities from the drainage pipe; meanwhile, the pressure intensity in the shell is increased, the flow speed of water in the drainage pipe is increased, and the drainage amount is increased; and the sewage discharge effect is further improved, blockage is prevented, the drainage amount is increased, and the use safety is improved.

Description

technical field [0001] The invention belongs to the field of building drainage, in particular to an internal fast drainage method for buildings. Background technique [0002] The domestic drainage system is to remove sewage and wastewater from residential buildings, public buildings and factory living rooms. The domestic drainage system can be further divided into: the domestic sewage drainage system that excludes flushing toilets and the domestic sewage drainage system that excludes washing wastewater. After treatment, domestic wastewater can be used as miscellaneous water for flushing toilets or greening; the internal drainage pipe of the building is a two-phase flow of water and air. In order to prevent toxic and harmful gases from entering the room due to the damage of the water seal caused by air pressure fluctuations, a ventilation system is required.

AI Technical Summary

Problems solved by technology

[0005] At present, building drainage generally uses pipelines for drainage. During the drainage process, pipeline blockages often appear, which brings more troublesome consequences to people's lives; in the prior art, the filtration method is generally used to filter larger impurities. Preventing it from entering the pipeline and causing pipeline blockage has played a certain preventive role, but it cannot fundamentally solve the problem of pipeline blockage; at the same time, when the traditional drainage pipe is draining, the water is directly tilted down by gravity. There will be a lot of noise, which will affect the sleep quality of the neighbors. It needs to be improved, and the noise pollution is small
