A household garbage shredding device

Abstract

The invention discloses a household garbage shredding device and belongs to the field of household garbage treatment. The device comprises a feeding mechanism, a shredding mechanism and a dischargingmechanism. The feeding mechanism comprises a liquid collecting cavity, a solid-liquid separating cavity and a feeding channel which are designed longitudinally from bottom to top in a stacked mode. The shredding mechanism comprises a primary shredding cavity communicating with the feeding channel and a secondary shredding cavity communicating with the primary shredding cavity. The discharging mechanism comprises a first discharging channel connected with an outlet of the primary shredding cavity and an inlet of the secondary shredding cavity, and a second discharging channel arranged at an outlet of the secondary shredding cavity. According to the household garbage shredding device, garbage materials can be classified before being shredded, garbage materials such as metal which does not need to be shredded are separated out, abrasion of products such as metal to tools can be reduced, and the working efficiency of the device is improved; and the garbage materials can be subjected to primary shredding, then continuous incremental shredding acting force is provided, and the shredding effect on the garbage materials is obviously good.

Description

technical field [0001] The invention relates to the field of domestic waste treatment, in particular to a domestic waste shredding device. Background technique [0002] With the rapid development of my country's economy and technology, people's living standards continue to improve, and more and more domestic garbage is produced. At present, there are two main ways to deal with garbage, incineration and landfill. These two treatment methods not only pollute and destroy The natural environment poses a threat to human health and wastes resources. Recycling useful garbage can promote the development of circular economy. In the recycling of available garbage, the shredder is an important tool. In the traditional shredding process, most of the large-scale transmission machinery is used. This process consumes a lot of energy and wastes The sewage is not easy to drain. [0003] At present, the garbage shredders on the market all include a shredding device, and the garbage materials...

AI Technical Summary

Problems solved by technology

But it has the following disadvantages: 1. Before the garbage materials are shredded, the garbage materials cannot be classified, and the garbage materials that do not need to be shredded are also shredded, which wastes the working time of the device and affects its work efficiency; 2. It is easy to cause tool wear or damage, which seriously shortens the service life of the tool; third, the design structure of the tool is too simple, and the shredding effect on garbage materials is relatively poor
