Description

Kitchen garbage grading processor

Technical Field

The utility model discloses a garbage disposer, in particular to kitchen garbage grading machine belongs to refuse treatment technical field.

Background

In 6 months in 2019, 9 departments such as the Ministry of housing and construction, etc. issue a notice about the comprehensive development of the domestic garbage classification work in cities on the national level and above, and decide to start the comprehensive domestic garbage classification work in cities on the national level and above since 2019. According to the notification requirement, as far as 2020, 46 major cities basically build a household garbage classification treatment system; other grade cities realize the classification and full coverage of the domestic garbage of the public institutions, and at least 1 street basically builds a domestic garbage classification demonstration area. In 2022, at least 1 region of each regional city realizes the classification and full coverage of domestic garbage; at least 1 street of other areas is basically built into a household garbage classification demonstration area. By 2025, a domestic garbage classification treatment system is basically built in cities on the national level and above.

The core of the garbage classification work in China is to separate the kitchen garbage of residents. According to the related documents, the yield of kitchen waste in the household garbage of residents is estimated to be 40-50%, but the kitchen waste collection rate is problematic. With reference to the progress of collection work in korea, usa, singapore, japan, and the like, the foreign kitchen waste collection rate is currently 3% to 21%; meanwhile, according to implementation opinions issued in 2019 and about implementation of the promotion of the whole-process classification system construction of 'Shanghai City domestic garbage management regulations', the goal of Shanghai City in 2019 is that the daily average control quantity of dry garbage is not higher than 21000 tons, the daily average classification quantity of wet garbage is higher than 5520 tons, and the target proportion of the wet garbage in the total garbage quantity is 21%.

The kitchen waste refers to perishable organic waste such as discarded fruit and vegetable and food leftovers, melon and fruit peels in household daily life, has the characteristics of high water content, high salt content, high oil content and the like, and is not suitable for landfill or incineration disposal.

At present, kitchen waste is developed in the direction of reduction, recycling and harmlessness in various countries, and because the design load of municipal sewage pipe networks and treatment systems in China does not consider the kitchen waste, even if the kitchen waste is treated by a common waste crusher and then is discharged into the municipal sewage pipe networks, the pipe networks are blocked, the water quantity and water quality load of sewage treatment plants are increased, even if the inside of the pipe networks is corroded, methane is generated, and the explosion risk is possibly caused. The key problem is that the particles of the garbage treated by the kitchen garbage crusher are large, so that pipe network blockage is easy to generate, and internal corrosion or methane can be generated only in the blocked state. People expect that after the kitchen waste is treated, the kitchen waste is discharged into a municipal sewage system, so that the problems of pipe network blockage, internal corrosion and the like are avoided, and the ideal effect of treating the kitchen waste is achieved.
