Description

Automatic crushing and sorting equipment of food leftovers}

The present invention relates to a technology for automatically separating and discharging the crushed food waste and contaminants by each type while smoothly crushing food waste.

Food waste is an essential part of human life. Especially, food waste generated in a culture zone where soup or stew is developed, such as Korea, contains a large amount of water, so it will rot when left at room temperature.

The food waste was treated by landfilling, but when landfilling, leachate is generated and contaminates soil and groundwater of landfill, and there are many problems such as waste of resources that can be recycled and used as compost or fertilizer.

These food wastes can be used as a good source of livestock feed or agricultural fertilizers, as long as they can only screen organic matter from which foreign substances have been removed. Although it is possible to do so, it does not have the proper sorting and crushing device until recently, and it is in the sad reality that precious resources are left intact.

In addition, the conventional food waste treatment apparatus remains in the technology of finely crushing and dehydrating food waste, and various miscellaneous matters such as bones, cutlery, forks, toothpicks, cotton gloves, vinyl, plastics, and bottle caps contained in food wastes. It is not suitable for livestock feed as it is not suggested to properly separate organic matter, which is a valid recycling resource, and is recycled at most as compost of agricultural products.

This not only results in a waste of valid resources, leading to enormous economic losses, but also results in a significant amount of waste, since large amounts of waste are generated because food waste cannot be recycled into animal feed and fertilizers. There is a problem.

As a prior art to solve some of these problems, "Patent Registration No. 444917, Name / Automatic Food Sorting Device for Sorting Food Waste and Its Foreign Matter Selection Method" has been proposed.

However, the prior art is that the vinyl is not properly separated and mixed together in the crushed food waste, so that the screening force is very low, in particular, the discharge port is formed on the upper vertical partition wall, so that metal impurities (chopsticks, etc.) are not smoothly discharged through the discharge port. It is stagnant without a problem, and the hammer hits the stagnant contaminants, causing a problem that frequently occurs that the hammer and the bolt fixing the hammer are broken.

In addition, since the blow plate and the perforated net is installed inside the case in a completely fixed state, when the blow plate and the perforated net are damaged, it is difficult to replace the maintenance situation.
