Description

A distributed kitchen waste treatment equipment

technical field

The invention relates to the field of garbage disposal, in particular to a distributed kitchen waste disposal device.

Background technique

At present, as we all know, with the progress of society and the improvement of people's living standards, the living environment is constantly improving, so the facilities of the family kitchen also need to be more perfect. Every family produces some food waste every day. If the food waste is not timely If handled, it will quickly rot, produce peculiar smell, and even seriously pollute the home environment. The traditional house garbage disposal machine is difficult to maintain, and it is also cumbersome to use.

Kitchen waste refers to the food residues after people eat and drink in daily life and the mixture of untreated food and water produced in the process of washing food and washing dishes. Its components mainly include peeled bones, meal grains, insoluble protein, fibrous and starchy insoluble organic matter, and its composition is extremely complex according to different meals. Because kitchen waste is rich in nutrients, if it is directly discharged into nature without treatment, under the action of suitable temperature and bacteria, it will spoil in a short time, which will not only pollute the surrounding environment, breed mosquitoes and flies, and occupy a large number of land, but also caused a lot of waste of resources. Based on this, there are currently kitchen waste treatment equipment that can process kitchen waste in the early stage. The main processing processes include crushing, dehydration, drying, and collection, so that kitchen waste can be turned into granular or powdery dehydrated materials. , reducing the space volume of kitchen waste, avoiding the environmental pollution caused by the rapid odor of kitchen waste, preparing for the later landfill or as a raw material for fertilizer, and realizing the reduction and resource reduction of kitchen waste. Chemical utilization will be of great significance.

Recently, as people pay more and more attention to environmental protection, the disposal of kitchen waste generated in the kitchen has gradually attracted widespread attention. Therefore, many other treatment methods have appeared recently, such as: the pulverization treatment method in which the kitchen waste is pulverized and then discharged into the sewer; the drying treatment method in which the garbage is reduced by forced drying using a dryer; Fermentation treatment method that is used as fertilizer or feed and then used; and elimination treatment method that uses microorganisms to eliminate kitchen waste, etc. Among them, the kitchen waste disposal machine is a special equipment for processing those perishable domestic organic wastes, such as leftovers, leftovers, peels, vegetable leaves, swill and other food wastes. In the machine, microorganisms in solid state are preset, and suitable temperature, humidity and oxygen supply conditions are provided. Put the garbage into the machine, and after 24 hours, the garbage can be decomposed by more than 90%. The microorganisms will generate a high temperature of 40-70 ℃ during the reaction process, which can kill most of the pathogenic microorganisms and parasites in the garbage. The residue can be used as fertilizer. Microorganisms will release a large number of decomposing proteins (also called enzymes) in the machine to decompose macromolecular organic wastes into low-molecular-weight organic substances such as sugars, fatty acids and amino acids. These organic substances are used as nutrients for microorganisms and metabolize water, gas and biothermal energy. . These microorganisms themselves multiply at a geometric rate, so that they continue to "eat" organic waste over and over again.

However, the existing kitchen waste disposal machines are extremely inconvenient during use, for example, the kitchen waste disposal machines emit foul-smelling irritating gases during the processing of kitchen wastes.
