A sewage pretreatment type green building drainage system

Abstract

The invention relates to the field of sewage discharge, in particular to a sewage pretreatment type green building drainage system. It includes a garbage disposer, the garbage disposer includes a housing, a main shaft, a grinding assembly, a first connection structure and a second connection structure; the grinding assembly includes a grinding frame, a grinding cylinder and a grinding disc, and a second A grinding structure, a second grinding structure is set between the grinding cylinder and the grinding disc, the main shaft drives the grinding disc to rotate and drives the grinding cylinder to rotate reversely through the transmission device, the main shaft and the transmission device are connected through the first connection structure, and the main shaft and the grinding disc pass through The second connection structure is connected. The invention can crush and grind the garbage in the sewage and discharge it after setting the garbage disposer to prevent clogging; at the same time, when the garbage disposer is stuck at the first grinding structure, the grinding cylinder can be reversely retreated through the first connection structure, and the grinding cylinder can be reversed in the second grinding structure. When the structure is stuck, the grinding disc can be raised and lowered through the second connecting structure to release the stuck.

Description

technical field

[0001] The invention relates to the technical field of sewage discharge, in particular to a sewage pretreatment type green building drainage system. Background technique

[0002] Green building refers to a building that saves resources to the greatest extent, protects the environment, reduces pollution, provides people with healthy, suitable and efficient use of space, and coexists harmoniously with nature throughout the entire life cycle of the building. The integrity of the drainage system in green buildings is closely related to environmental protection issues.

[0003] The kitchen in the green building is a place that produces more perishable, smelly and deteriorated garbage, and people put forward higher requirements for the reliability and environmental protection of its drainage system. Most of the existing green building kitchen drainage systems directly put part of the kitchen waste into the sink and discharge it directly, and it is easy to cause bl...
