Description

[0001] This application is a divisional application of the patent application entitled "A Intelligent Aerobic Fermentation System for Underground Garbage". The application date of the original application is December 21, 2020, and the application number is 202011533704.7. Technical Field

[0002] The invention relates to the technical field of garbage recycling and processing equipment, and in particular to an underground garbage intelligent aerobic fermentation system. Background Art

[0003] In June 2016, the Ministry of Housing and Urban-Rural Development and the National Development and Reform Commission issued the "Waste Mandatory Classification System Plan (Draft for Comments)". The plan proposes that by the end of 2020, domestic waste in key cities will be effectively classified, and the coverage rate of classified collection of domestic waste in key cities that implement mandatory classification of domestic waste will reach more than 90%, and the recycling rate of domestic waste will reach more than 35% (including recycling of renewable resources, classified collection and resource utilization of kitchen waste and other perishable organic waste). Classified kitchen waste and other perishable organic waste and sludge waste can be aerobic fermented, which can not only achieve harmlessness, reduction and resource utilization, but also generate certain economic benefits.

[0004] At present, according to the characteristics of fermentation, most high-temperature aerobic fermentation devices adopt vertical and horizontal fermentation cylinders and are all set on the ground. Among them, most of the fermentation cylinders are cylindrical, and few equipment are equipped with exhaust devices to extract water vapor and exhaust gas inside the fermentation cylinder. The heat generated by the degradation of organic matter by microorganisms during fermentation causes the water in the material to evaporate. However, this part of the water vapor cannot be extracted from the cylinder in time, and will return to the material again after condensation, slowing down the heating rate of the fresh material, thereby affecting the maturation process of the material. Therefore, it is difficult for existing fermentation equipment to achieve moisture removal in a short period of aerobic fermentation, and it is difficult to meet the requirement of moisture content ≤30% in the "Organic Fertilizer Standard" (NY525-2012).

[0005] At present, there are some technologies and equipment for reducing and recycling domestic waste, but the existing equipment has low automation, high cost of microbial agents and auxiliary materials, large floor space, complicated supporting facilities, serious secondary pollution (waste gas, wastewater), poor environmental sanitation conditions and other problems. It cannot adapt to the shortage of land resources and the characteristics of urban waste, and seriously limits the resource utilization of organic degradable components in urban domestic waste and the reduction of domestic waste at the source. Summary of the invention

[0056] like Figure 1 , Figure 2As shown, the working principle of the underground garbage intelligent aerobic fermentation system is as follows: first, the garbage is transported to the garbage transfer room 1 set on the ground by a garbage truck, and then the garbage is dumped into the garbage input bucket 5 by the automatic unloading bucket of the garbage truck. The lower end of the garbage input bucket 5 corresponds to the position of the feeding end of the garbage conveyor belt 4.1 in the underground conveyor belt 4. The garbage is transported forward by the garbage conveyor belt 4.1. During the process of being transported on the garbage conveyor belt 4.1, the garbage is sorted and recycled by various material sorters set above the garbage conveyor belt 4.1. The remaining organic garbage that can be used for aerobic fermentation is transported to the organic garbage buffer storage chamber 6, and is transported to the organic garbage fermentation chamber 7 by the intelligent robot 9 for material transportation and material dumping for fermentation treatment. During the fermentation process, the intelligent robot 9 for material transportation and material turning continuously turns the material until the aerobic fermentation process of the material is completed. The intelligent robot 9 for material transportation and material turning then transfers the fermented fertilizer to the lifting device 10 through the fertilizer conveyor belt 4.2, and then lifts the fermented fertilizer to the ground through the lifting device 10. Finally, the transport vehicle parked on the ground transports the fermented fertilizer out. The garbage sorter arranged above the garbage conveyor belt 4.1 sorts different types of non-fermentation garbage into material collection boxes. A lifting device 10 is arranged under each material collection box. The collection box full of materials is lifted to the ground by the lifting device and then transported away by a transport vehicle. The above operation process is automatically completed by the PLC controller arranged in the garbage disposal control room 2 on the ground.
