Kitchen waste sorting device

Abstract

The invention discloses a kitchen waste sorting device, wherein a containing cavity is provided with an oblique bottom wall; aerator pipes are laid on the oblique bottom wall; kitchen waste is poured into the containing cavity from a higher side at the bottom of a bucket body; heavy impurities sink to the bottom of the containing cavity, and slide to a lower side along the oblique bottom wall, and light impurities, such as plastic bags, plastic bottles, residues, float upward to the upper part of the containing cavity because of the buoyancy and under the effect of the aerator pipes. Correspondingly, a lower side at the bottom of the containing cavity is provided with a first impurity conveyer capable of outputting heavy impurities sinking to the bottom out of the bucket body, and the upper part of the containing cavity is provided with a second impurity conveyer capable of outputting light impurities floating to the upper part of the containing cavity out of the bucket body, and finally, water, kitchen waste slurry, oil and floating residues are left in the bucket body; a pump also can be used for conveying materials in the bucket body to the next working procedure to treat; water removed from the kitchen waste in the subsequent working procedures can be recycled for adjusting the water content of kitchen waste.

Description

technical field [0001] The present application relates to a treatment of kitchen waste, in particular to a device capable of sorting food waste. Background technique [0002] With the development of our country's social economy and the improvement of people's living standards, the amount of kitchen waste generated is increasing. The orderly management of kitchen waste has become a new topic for our country's urban managers, and it has become a problem that restricts the development of our country's cities. obstacle. Especially after successive incidents of melamine, clenbuterol and waste oil, etc., the state has raised the treatment of kitchen waste to a major food safety project, and successively issued the "General Office of the State Council on Strengthening Waste Oil Remediation and Kitchen Waste Management" A series of policy documents such as "Opinions" require all localities to carry out food safety rectification work as soon as possible; through the implementation o...

Problems solved by technology

These machines can separate one or more kinds of impurities, but there are also some disadvantages: for example, the bag breaking machine is mainly aimed at plastic bags, which break the plastic bags and remove them as light substances, but after the plastic bags are broken, the fine fragments are mixed in the slurry and it is difficult to separate Thoroughly, it is very unfavorable to the subsequent anaerobic or feed; drum sieve has a good separation effect on large impurities, but cannot remove small knives and forks, stones and other impurities thoroughly; magnetic separator is not good for aluminum tableware and Some stainless steel tableware is invalid; the integrated crushing and sorting machine crushes all impurities before sorting them. Stones, glass, stainless steel and other impurities in the impurities will cause great damage to the crusher, and the plastic bags are crushed and mixed in the slurry It is also difficult to separate completely
