Food waste pretreatment device

Abstract

The invention relates to a pretreatment device for kitchen garbage. The device consists of a box and stents, a material bucket arranged between the left and right stents and separated into a moulding chamber and a crushing chamber by a pressure plate, a transverse discharging pressure plate is provided in the moulding chamber, a baffle board positioned at the lower part of the moulding chamber, a feeding port disposed at the upper right of the crushing chamber, an AC (alternating current) dynamo and a decelerator that are mounted under the material bucket and are in connection with the crushing chamber and the moulding chamber through a chain gear rotation instrument connected to a cutterhead by a screw, an electromagnetic clutch installed on the chain gear rotation instrument, a discharging box fixed on the left of a box bottom board, and a water receiving box on the right side of the discharging box. With the device of the invention, on-site garbage treatment can be realized, and after the processes of crushing, dehydration, moulding, high temperature disinfection and peculiar smell removal, no environmental pollution can be caused. Meanwhile, providing raw materials for the resource utilization of kitchen garbage, the device provided in the invention has the advantages of convenient usage, high efficiency and cleanliness, as well as low operation cost.

Description

technical field [0001] The invention belongs to the field of garbage treatment, and in particular relates to a kitchen garbage pretreatment device. Background technique [0002] Kitchen waste is the domestic waste formed by residents in the process of living consumption. Residential areas, restaurants, and canteens of various enterprises and institutions are the places where it is discharged intensively. Generally, food residues produced during food processing are called "kitchen waste" and food residues after dietary consumption are called "slops". The former is mainly composed of vegetable leaves, fruit peels, and high in carbohydrates; the latter is mainly composed of starch, protein, and fat, and also has the characteristics of high salt content and a large proportion of free fat, which is easily used by microorganisms and has a high water content. [0003] For a long time, food waste has been used as feed for pigs in our country, and they have found their own way out t...

Problems solved by technology

There are many problems in this treatment method: 1. The garbage has a high moisture content and high fluidity, which is very easy to leak, causing secondary pollution, and a large number of mosquitoes and flies, which affects environmental sanitation; 2. Garbage trucks seriously affect the daily traffic in the city and pollute the environment; 3. Without any treatment, some of these garbage have deteriorated during transportation, and the sanitation of the pigs is worrying, which may easily lead to the occurrence and spread of diseases such as foot-and-mouth disease

Municipal waste disposal methods usually include incineration and landfill. If municipal solid waste is incinerated, since the moisture content of kitchen waste is often as high as about 90% and the calorific value is about 2100KJ / kg-3000KJ / kg, it should be carried out together with other waste. Incineration will not only fail to meet the calorific value requirements of waste incineration power generation (about 5000KJ / kg), but will cause insufficient combustion in the incinerator and produce dioxins and other substances; High moisture content not suitable for handling

Moreover, incineration and landfill will lead to a large amount of waste of organic matter
