Drainage device in building

Abstract

The invention discloses a drainage device in a building. The drainage device comprises a shell, a downpipe and a drainage pipe, wherein a rotating cylinder is arranged in the shell, the upper end of the rotating cylinder is connected with the downpipe, a filter screen is arranged on the inner side wall of the rotating cylinder, and a plurality of through holes are formed in the side wall of the rotating cylinder; the shell is of a sealed structure, and the bottom of the shell is connected with the drainage pipe; a rotating shaft is arranged at the bottom of the rotating cylinder, a spiral cutter is arranged on the rotating shaft, the other end of the rotating shaft is connected with a second gear, the second gear is connected with a first gear in a meshed mode, the first gear is connected with a worm, and the worm is connected with a worm gear in a matched mode to drive the first gear to rotate; and the downpipe is connected with a pressurizing pipe, the other end of the pressurizing pipe is connected with an air pressure mechanism, and the air pressure mechanism conducts air pressurizing on the downpipe. The sewage discharging 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 a drainage device inside a building. Background technique [0002] The domestic drainage system is to exclude the sewage from residential buildings, public buildings and factories. The domestic drainage system can be further divided into: a domestic sewage drainage system that excludes flushing toilets and a domestic sewage drainage system that excludes washing wastewater. Domestic wastewater can be treated as miscellaneous water for flushing toilets or landscaping; there is a two-phase flow of water and gas in the drainage pipes inside the building. To prevent toxic and harmful gases from entering the room due to pressure fluctuations, a ventilation system is required. [0003] Chinese Patent Application No. 201921500682.7 discloses an anti-blocking device for a building drain pipe, comprising a water collecting tank, and an upper drain pipe is fixedly connected to the side wal...

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
