Description

A kind of kitchen waste recycling processor

technical field

The present invention relates to a kitchen garbage collection and recycling processor.

Background technique

At present, many urban and township community household kitchen wastes have not been sorted. The kitchen waste and household waste are mixed into garbage bags and placed in the community trash cans. The garbage removal personnel dump the trash cans into garbage trucks and transport them to the garbage transfer station. It is poured into the compressor, compressed and then loaded into a large-tonnage garbage truck and transported to the suburban garbage disposal center for many garbage treatment processes such as bag breaking, sorting, magnetic separation, composting, etc. After the bag is broken, the garbage is mixed with the garbage bag. Sorting out garbage bag fragments is a complicated process. The sorting is difficult, the working environment emits odor, and there are many processes and a long time, which increases the degree of corruption of the meal waste. Every day, a large amount of domestic waste cannot be processed in time due to the lack of sorting and processing facilities.

In some areas, garbage classification is implemented, but can it also be classified and disposed of at the garbage station? The kitchen biomass is basically treated as ordinary household garbage and mixed with other garbage, which discourages the citizens' enthusiasm for garbage classification.

The growing number of urban kitchen waste and the lagging way of collection, transportation and treatment have caused more and more serious problems such as environmental pollution and health, as well as affecting the city's image. Many countries have attached great importance to it and require the source of food waste to be treated in a harmless and resourceful manner, and many cities have active plans for the recycling of food waste. In my country's cities and towns, a large amount of kitchen waste is generated, and the resources are disposed of and reused on-site. The kitchen waste is converted into fertilizers that can be absorbed by plants through biological fermentation, so as to meet the development requirements of a beautiful environment in the new era of my country. Many cities and towns have effectively implemented waste sorting and delivery. Some community households have entered the age of intelligence and information, and they can identify the information of the throwers. Many enterprises and scientific research units have studied kitchen waste and proposed a variety of Processing equipment and methods, but the equipment is not suitable for community on-site processing needs due to the complex processing technology, the equipment is too large, and the floor area is large. Therefore, it is particularly important to develop community kitchen waste recycling equipment with high efficiency, small footprint, and no need for municipal drainage pipes.

The medium temperature stage of the first tank is 30°C-45°C, the high-temperature stage of the second tank is 50°C-65°C, the decomposing stage of the third tank is 20°C-35°C, and kitchen waste The rapid biochemical reaction is carried out in the heated, stirred and forced ventilation tank reactor 41, and the aerobic microorganisms decompose the macromolecules of the garbage organic matter into small molecular protein fragments or further decompose into amino acids, so that the organic matter in it is converted into simple inorganic matter And realize the biochemical process of autologous growth, which can convert organic matter into humus, H2O and CO2, high temperature can effectively kill various pathogens in kitchen waste, form stable and hygienic humus fertilizer, and realize harmless kitchen waste. processing. good organic fertilizer.

The filter plate 4113 at the bottom of the tank filters out the material leachate and enters the second reaction chamber 4115. The second reaction chamber 4115 is filled with decomposed materials from the biochemical treatment of kitchen waste as fillers. Wood chips can also be used as fillers, or a mixture of wood chips and decomposed materials can be used as fillers, and the fillers can be stirred and mixed with leachate for biochemical reaction. The 2 second stirrers 417 rotate and stir intermittently in different rotation directions to form an internal circulating flow pattern, the leachate is attached to the filler, the microwave heating device heats the filler, the gas distribution device is forced to ventilate, and aerobic microorganisms are used to remove tiny organic matter in the liquid. The solid matter is absorbed, decomposed and oxidized by microorganisms, so that the organic matter in it is converted into simple inorganic matter, H2O and CO2. The second fan 4128 draws out the exhaust gas in time and takes away the H2O and CO2 for discharge through the exhaust gas treatment device to complete the microbial decomposition of the leachate. Sewage treatment. The filler is replaced after a few months, and the replaced filler is transported to the treatment plant for post-processing with other decomposed materials to make fertilizer, which will no longer cause secondary pollution.

The humidity control device detects the humidity of materials and fillers and implements automatic adjustment to maintain the humidity environment required for biochemical reactions. In the middle and late stage of the biochemical reaction, when the water content of the first reaction chamber is sometimes too low after a long time of heating, fermentation, forced ventilation and exhaust gas extraction, the water spray valve set in the first reaction chamber is automatically opened to spray water to the material, adjusting The moisture content of the material meets the needs of the biochemical reaction.

The first reaction chamber 4114 and the second reaction chamber 4115 are equipped with forced ventilation device, exhaust gas treatment device, humidity control device and temperature control device. The gas of H2O and CO2 is deodorized and discharged harmlessly through the exhaust gas treatment device, and forced ventilation provides materials and filled with sufficient oxygen.
