Description

TECHNICAL FIELD

[0001] The present application relates to the field of household garbage classification and resource utilization, and in particular to a household garbage transfer and disposal integrated station system and method based on high-pressure extrusion. BACKGROUND

[0002] Before household garbage enters incineration and landfill facilities, according to existing regulations, the total recycling rate of recyclable and perishable garbage should be more than 35%. County-level areas should accelerate the establishment of a household garbage management system that includes classified disposal, classified collection, classified transportation, and classified treatment, so as to effectively cover the household garbage classification system. In our daily life, perishable garbage accounts for about 40-60% of household garbage, and is also the source of odors in communities and transfer stations, often causing complaints. Perishable garbage is prone to leakage during garbage transfer, and concentrated disposal at the back end can produce a large amount of leachate, low heat value, and dioxin during incineration. The key to the implementation of garbage classification policy is to solve the problem of dry and wet separation. However, in reality, garbage classification is not complete, and the source of garbage classification often mixes recyclable, kitchen waste, other, and hazardous waste into one category, or mixes other and kitchen waste into one category. In areas practicing garbage classification, manual intervention is often required, and fixed-point personnel on duty increases the cost of classification. The problem of breaking or not breaking the bag during the disposal of kitchen waste has always been a headache for residents.

[0003] Currently, the processing and disposal of garbage transfer stations do not closely link with the classification results of the previous stage, and neither can they cover up the mistakes of the previous stage nor can they save effort for the efforts of the previous stage. If garbage classification equipment is introduced into the transfer station, it can effectively solve the problem of dry and wet separation of household garbage. Many garbage classification devices have been developed at home and abroad, but they all have problems such as long process flow, high equipment failure rate, poor classification effect, high energy consumption, high investment, and high classification cost.

[0004] Chinese patent CN201010576563.7 discloses a garbage classification and treatment device, which breaks the garbage bag through a bag breaking system, screens out magnetic substances in the garbage after breaking the bag, screens out impurities such as gravel and glass in the garbage through a screening system, and finally screens out plastic and dust in the garbage through an air separation system. Although this treatment process can achieve the classification of household garbage, a large amount of organic matter is lost in the magnetic separation and screening system, affecting subsequent resource utilization.

[0005] The Chinese patent CN202021897819.X discloses a new type of environment-friendly household garbage classification treatment equipment, a dry garbage recycling bin and a ground, a first toothed roller is arranged on the left side of the inner cavity of the recycling bin, a second toothed roller is arranged on the right side of the inner cavity of the recycling bin, a biogas tank is arranged on the right side of the ground, and first, second and third stirring leaves are arranged on the two sides of the upper, middle and lower parts of the biogas tank. The treatment process realizes the resource utilization of household garbage, but in the aspect of garbage classification, the household garbage cannot be effectively classified, and it is difficult to cope with complex household garbage.

[0006] The Chinese patent CN201010196980.9 discloses a household garbage automatic sorting equipment and method, which realizes bag breaking and crushing treatment of materials through relative tearing force generated by the up-down raking mechanism. The household garbage automatic sorting equipment sorts household garbage into three categories of heavy small-scale garbage, heavy large-scale garbage and light large-scale garbage, but cannot effectively separate wet components such as kitchen waste and kitchen waste in household garbage.

[0007] Therefore, the existing garbage transfer station cannot save effort for the previous efforts, and cannot cover up the mistakes in the previous garbage classification. The existing household garbage classification treatment equipment and treatment method cannot meet the needs of effective separation and resource utilization of household garbage in the new household garbage transfer and disposal integrated station, and is difficult to adapt to household garbage. In addition, there is no system and method for solving the poor classification effect of community residents' garbage. SUMMARY

[0008] The purpose of the present application is to provide a household garbage transfer and disposal integrated station system and method based on high-pressure extrusion, which can effectively handle the mistakes made during the garbage classification process, and can alleviate the processing pressure of the surge of organic garbage caused by garbage classification, thereby solving the above technical problems existing in the prior art.

[0019] A household garbage transfer disposal method based on high-pressure extrusion, adopts the household garbage transfer disposal integrated station system based on high-pressure extrusion, and comprises the following steps:

[0020] The garbage storage pit of the system receives and stores the household garbage collected and transported by the garbage collection and transportation vehicle;

[0021] The conveying device of the system conveys the household garbage stored in the garbage storage pit to the high-pressure extrusion dry-wet separation and quality separation equipment of the system;

[0024] The wet garbage is conveyed to the ultra-high temperature aerobic fermentation equipment of the system through the wet garbage conveying device of the wet garbage outlet of the high-pressure extrusion dry-wet separation and quality separation equipment, and after the organic fertilizer is prepared under the action of the ultra-high temperature bacteria, the organic fertilizer is exported through the organic fertilizer outlet.

[0025] Compared with the prior art, the household garbage transfer disposal integrated station system and method based on high-pressure extrusion have the following beneficial effects:

[0026] By setting the high-pressure extrusion dry-wet separation and quality separation equipment, the domestic waste sent to the transfer station and stored in the waste storage pit can be subjected to high-pressure extrusion treatment, realizing the classification of dry and wet waste, and the dry waste compressor and dry waste collection device are arranged respectively, so that the classified dry waste can be further compressed and treated, facilitating the external transportation to the waste incineration plant, and the ultrahigh-temperature aerobic fermentation equipment is arranged, so that the classified wet waste can be further subjected to high-temperature fermentation treatment, and organic fertilizer is prepared for resource utilization. The system can not only solve the mistakes in the garbage classification process, but also alleviate the treatment pressure of the increasing organic waste caused by garbage classification, thereby solving the shortcomings of the existing domestic waste transfer station, reducing the garbage classification treatment cost, improving the garbage classification efficiency, and reducing environmental pollution.

At the same time, the system can realize 24-hour automatic continuous operation and unattended operation. BRIEF DESCRIPTION OF DRAWINGS
