Background technique

As people's awareness of environmental protection is getting stronger and stronger, the problems of environmental pollution and waste of resources have received great attention, and the treatment of municipal solid waste has also attracted much attention. Kitchen waste is one of the most generated garbage in people's daily life. Usually, people throw kitchen waste directly into the trash can. Garbage trucks regularly collect the garbage in the trash can and send the collected garbage to the garbage treatment plant for disposal. Kitchen waste refers to the organic perishable waste generated by residents’ family life, including food trade, waste in the production process and leftover waste, such as rice, pasta, expired food, meat, fish and shrimp (including shells), Crab shells, shells, bones, vegetables, melons and fruits, skin cores, bagasse, tea residue, durian shells, coconut shells, and discarded branches (leaves) of household potted plants, etc. Kitchen waste is part of domestic waste, so it is generally required The sorting machine is used to crush the garbage and then perform solid-liquid separation, followed by subsequent operations such as oil-water separation, organic fermentation, and inorganic collection, so that kitchen waste can be fully recycled.

When the existing kitchen waste is automatically crushed and sorted, the liquid is automatically dropped to the desired position for collection only by cutting, and at the same time, the solid waste is transported to the designated position to achieve solid-liquid separation. The separation efficiency of this separation method is At the same time, there will still be more liquid components in the subsequent solid waste that are difficult to fully remove, which will affect the subsequent recycling of the waste. In addition, once the blade touches hard things when it rotates, it is easy to cause the scraper to be stuck or squeezed.
