Description

Smashing device and garbage treatment system

Technical Field

Background

At present, environmental problems and safety problems caused by domestic garbage become more and more serious along with the improvement of living standard and the development of urbanization of people, and how to treat the domestic garbage becomes a major subject for environmental protection and urban management. In order to meet the challenge, governments of various countries start to gradually popularize garbage classification trial points so as to realize more efficient and environment-friendly garbage treatment, and particularly propose to adopt new technology and new equipment to popularize kitchen garbage crushing treatment.

Currently, the commercial crushing treatment of kitchen waste is mainly realized by a kitchen waste treatment device installed below a sink. Specifically, bones, vegetable leaves, leftovers and the like poured from the water tank are ground into debris by a garbage disposal device installed below the water tank, and then directly flushed into a sewage discharge pipeline through a sewer.

The garbage disposal device generally crushes the food garbage for a predetermined time, and uniformly pours the crushed food garbage into the sewage discharge pipeline after the food garbage is completely crushed. However, during the process of crushing the food waste, a part of the food waste is fully crushed, and the size of the food waste reaches the size requirement of sewage discharge, but the food waste still remains in the crushing cavity. This not only will occupy the finite space of crushing chamber, influence and continue to add food waste to crushing intracavity, but also can hinder the stirring of other not fully stirred up food waste, reduced the stirring efficiency of refuse treatment device.
