Description

Kitchen waste community centralized treatment device and method

Technical Field

The invention relates to the field of garbage classification treatment, in particular to a kitchen garbage cell centralized treatment device and method.

Background

In recent years, China has begun to implement waste classification. In the waste sorting process, the kitchen waste is the most complicated in the sorting process due to its inherent characteristics. At present, the mainstream disposal method is to set a fixed special garbage can in a community, equip a special person for guidance and supervision, regularly and regularly put residents at fixed points, and then transport the garbage can to a centralized processing point by a special transport vehicle for subsequent processing (including sorting and crushing).

There are some problems with this approach: firstly, the method is very inconvenient, and residents cannot throw the Chinese herbal medicine in a specified time period; secondly, a special garbage can and a special transport vehicle are needed, and the garbage can and the transport vehicle need to be cleaned after being used each time, so that the environmental pollution is easily caused; thirdly, after the kitchen waste is transported to a centralized treatment point, a plurality of programs are required to be treated, and the operation and management cost is high on the whole.

There are also solutions in the industry to these problems, which are summarized mainly in relation to local processing and automatic classification.

In terms of local processing, there are currently two main categories:

one type is to directly process at home, and the household kitchen garbage processing equipment is used and is arranged below a kitchen vegetable washing basin, so that kitchen garbage can be smashed and flushed away from a sewer. The device is only suitable for being used in families, and because the pipe diameter of a sewer in the families is small, and because of eating habits, grease in kitchen garbage is more, and the sewer is easy to block, the popularization rate of the device is low at present;

the other type is processing equipment for unit canteens, which is mainly used for centralized processing of leftovers in the unit canteens, and the equipment needs to be watched and used by a specially-assigned person, can be basically used in the canteens and is not suitable for self-service use in a community.

In the aspect of garbage classification automation, there are also some related technologies, and there are four main categories:

a. AI intelligent recognition of domestic waste reports to the police: the intelligent garbage can house is utilized to collect and identify household garbage images; intelligently prompting to put in and classify the garbage can according to the garbage category; adopt integrated intelligent processing unit's garbage bin, can find wrong input and report an alarm when the resident emptys rubbish immediately.

b. Automatic classification of household garbage: through rubbish data training and test, establish the domestic waste intelligent classification system based on artificial intelligence, the automatic classification robot or the intelligent grab bucket of refuse handling transfer station snatch the rubbish of various shapes through the manipulator, discern recoverable rubbish, harmful rubbish etc. put in the recovery processing device of difference. The image recognition technology is used for centering the garbage transferred into the container, judging the batch quality of the garbage, and preventing the prior missed detection and dangerous goods.

c. Categorised clearance of intelligence domestic waste: the different types of household garbage cleaning and transporting vehicles automatically identify and classify the garbage cans, and the garbage cans are collected and transported to ensure the classified collection and transportation. The collection process of the wet garbage in the residential area is recorded through vehicle-mounted camera shooting and image sensing equipment, and when the wet garbage is dumped into the vehicle, impurity identification is carried out and alarm is recorded.

d. Garbage recycling robot: the problem that residents cannot throw garbage at fixed time and fixed point is solved. The resident can issue an instruction through the APP, and after receiving the instruction, the community robot starts the GPS and the motion sensor of the resident to position the designated place of the resident. When the garbage can arrives at a designated place and meets residents, the residents can put classified garbage into specific pockets of the robot, and the robot can automatically put the garbage into different garbage cans.

Generally speaking, although there are some products and technologies oriented to a certain aspect of garbage disposal, such as classification, identification, recycling, etc., there is no systematic solution and product that can be widely applied. With the implementation of garbage classification in more cities in the future, the problem of classification treatment of kitchen garbage is more prominent.
