Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of garbage, in particular to a material discharging, sorting and recycling device for a biochemical treatment machine. Background Art
[0002] At present, the kitchen waste treatment industry generally uses screening to separate the solid organic matter and solid inorganic matter in the collected kitchen waste. The under-screen material smaller than the mesh size is assumed to be solid organic matter, and the over-screen material larger than the mesh size is assumed to be solid inorganic matter. The solid inorganic matter in kitchen waste is mostly treated by incineration or landfill, and the solid organic matter in kitchen waste is treated by solid anaerobic fermentation, liquid anaerobic fermentation after slurrying, or solid aerobic fermentation. Due to the complex composition of kitchen waste, this sorting method has great uncertainty and cannot accurately distinguish the organic and inorganic matter in kitchen waste. Since kitchen waste treatment is a large-scale, industrialized and centralized treatment, there is currently no better sorting method, which also leads to the mixing of more inorganic matter when using biochemical treatment machines to treat the solid organic matter in kitchen waste.
[0003] Biochemical treatment machine is a device that uses biological enhanced humification technology to aerobic fermentation treatment of organic waste. It is used to quickly and efficiently treat solid organic matter after kitchen waste sorting to obtain soil conditioners or biological fermentation products. Put organic waste and conditioning materials into the biochemical treatment machine in a certain proportion, and add an appropriate amount of bacteria. Under specific temperature, humidity, pressure and oxygen supply conditions, the microbial strains grow and multiply rapidly, and the fermentation process is completed after a certain period of time, realizing the resource utilization of organic waste. Due to the influence of the accuracy of the sorting equipment, the biochemical treatment machine products contain a large amount of debris, including bones, plastics, fibers, product agglomeration particles, etc. In some areas, due to the influence of garbage classification quality, the proportion of debris in biochemical treatment products is more than 10%, which greatly affects the output and production energy consumption of the products. The bones and product agglomerates in the debris have a high recycling value. After the bones and product agglomerates are reused, they can improve the fluffiness of the materials in the biochemical treatment machine and increase the specific surface area of the materials, which not only ensures the effect of aerobic fermentation but also accelerates the loss of water in the materials and reduces the operating energy consumption of the biochemical treatment machine. When reused, the bones and product agglomerates in the debris are stirred and rubbed by the stirring blades of the biochemical treatment machine, and some of them are changed from large particles to small particles or even powdered, which increases the minerals in the product and improves the quality and output of the product.
[0004] At present, in the process of kitchen waste, material sorting and recycling equipment is needed to process the kitchen waste to facilitate the sorting of kitchen waste. However, when treating kitchen waste, due to the complex composition of kitchen waste, the debris sorted out by the biochemical treatment machine contains impurities with recycling value. If it is directly discharged, it will cause a waste of resources and increase the cost of the product.
[0005] In view of the above problems, a biochemical treatment machine discharge sorting and recycling equipment is proposed. Utility Model Content
