Energy-saving and environment-friendly building drainage device

Abstract

The invention relates to the field of drainage structures, in particular to an energy-saving and environment-friendly building drainage device. An opening in the upper end of a grinding cylinder is communicated with a building wastewater pool, an upper transmission shaft is arranged in the grinding cavity, an upper fixing ring is fixed to the opening of the grinding cavity, and an adjusting rotating ring is rotatably arranged on the upper transmission shaft; multiple upper torsion bars are evenly distributed in the circumferential direction of the upper transmission shaft, the upper end of each upper torsion bar is universally hinged to the upper fixing ring, and the lower end of each upper torsion bar is universally hinged to the adjusting rotating ring; the upper grinding mechanism comprises multiple upper grinding discs and multiple upper crushing cutters; the upper grinding disc is in a vortex disc shape, a groove body in the upper grinding disc is a vertically-communicated through groove, the rotating direction of the groove body in the upper grinding disc is opposite to the rotating direction of the upper transmission shaft, and the upper grinding disc is rotatably arranged on the upper transmission shaft in a sleeving mode and can slide up and down; and the upper crushing cutters can be arranged on the upper transmission shaft in a vertically sliding and sleeving mode, and each upper crushing cutter is arranged between every two adjacent upper grinding discs, so that when the upper crushing cutters conduct crushing and grinding, stress is uniform, and the upper crushing cutters are prevented from being damaged.

Description

technical field [0001] The invention relates to the field of drainage structures, in particular to an energy-saving and environment-friendly building drainage device. Background technique [0002] Drainage devices in buildings generally use drainage pipes to discharge sewage and wastewater. However, domestic sewage and wastewater often contain a large amount of garbage and impurities, which will cause blockage of drainage pipes and affect normal drainage. Most of the anti-blocking settings in the current building drainage devices use anti-blocking nets to filter impurities, crush larger impurities into materials with small apertures, and then discharge them without affecting drainage. During the crushing process, the conventional crushing device, due to the uneven material size and quantity, has different losses for different cutters, which will cause some cutters and devices to be more easily damaged, which has a great impact on the operation of the device.
