Description

Dry and wet garbage classification and collection system and collection method

Technical Field

The invention belongs to the technical field of dry and wet garbage classification and recovery, and particularly relates to a dry and wet garbage classification and collection system and a dry and wet garbage classification and collection method for automatically monitoring and collecting dry and wet garbage.

Background

According to the existing garbage classification method, the household garbage is generally classified into wet garbage, dry garbage, recoverable garbage and harmful garbage. The wet garbage is also called kitchen garbage and organic garbage, namely perishable garbage, and refers to perishable biomass domestic wastes such as food material waste, leftovers, overdue food, melon peel and fruit stone, green plants of flowers, traditional Chinese medicine dregs and the like; the dry garbage has the most abundant composition types, and the wet garbage can be recovered, and the garbage except the harmful garbage belongs to the type.

In order to realize effective treatment of garbage, more and more cities are added into a row and a column for classified garbage throwing, and primary classification is carried out at a throwing source. In order to effectively carry out garbage classification, most cities adopt a mode of regularly and fixedly throwing garbage, residents can only throw garbage in a specific time period every day, and special persons check classification effects in garbage houses to guide and correct the garbage which is not classified on site. However, this method is difficult to implement for a long time and has obvious defects: (1) the time of limiting rubbish throwing in means that rubbish can only be piled up at home, and at the time period of non-rubbish throwing in, rubbish can only be loaded in the plastic bag and placed in indoor one corner, and the time period of waiting for rubbish to deliver comes the back and takes out the open air. If the delivery period is missed, the user can only wait for the next period or even the next day for delivery. After the garbage is putrefactive after being placed for a long time, the emitted air is remained in the room to cause indoor air pollution, which is particularly the case in summer. (2) The mode that the special person inspects in the garbage room is adopted, so that the labor consumption is huge, the effect is not good, and careless omission exists only by observing with human eyes.

In order to develop a garbage classification habit as soon as possible, an integral reward system is released in certain areas, each garbage can room is provided with four intelligent delivery doors, and garbage cans are arranged behind the doors and are respectively used as wet garbage, dry garbage, recoverable garbage and harmful garbage recycling cans. The resident puts in through modes such as punching the card, button, puts in different rubbish to different boxes, and the system can carry out the integral automatically according to the weight that the resident put in different rubbish. Although for some residents who are not interested in the points or the old who do not know how to use the equipment, the point reward system does not necessarily lead the residents to change the habits fundamentally, and the garbage is still mixed together. Even in the case of no supervision, the points are collected, but the garbage is still loaded in a mixed mode.

One of the basic principles of environmental protection is "pollutant remediation", which is often expressed as "pollutant payment". According to this principle, the initial source of domestic waste pollution-the domestic waste producer, should bear the cost of waste disposal. Therefore, the charging of the garbage is a necessary trend, and the garbage classification awareness of residents can be fundamentally improved.

From 1/5/2020, the new edition "regulations on managing domestic waste in Beijing City" was formally implemented. In order to cooperate with the implementation of the regulation, Beijing city also printed the action scheme of classifying domestic garbage and four implementation methods, and the policy of 'flexibility' is advanced in sequence. The charge regulations directly related to the treatment of the domestic garbage are as follows: the eighth local market gradually establishes a domestic garbage treatment charging system with metering charging, classification charging and easy collection according to the principles of multi-discharge multi-payment, less-discharge low-payment, mixed garbage multi-payment and classified garbage low-payment, strengthens charging management and promotes reduction, classification and resource utilization of domestic garbage. The concrete method is established by the city development and reform department meeting the city management, finance and other departments of the city. The unit and the individual who produce the domestic garbage should pay the domestic garbage disposal fee according to the regulations.

However, the currently used intelligent garbage recycling system mainly aims at recyclable garbage, and can only realize the function of card swiping for delivering the garbage, and is difficult to support the policy enforcement. In fact, in all garbage categories, the proportion of dry garbage and wet garbage is the largest, accounting for 70-80% of the total garbage amount, and the generation frequency is high every day. In daily life, the production amount of recoverable garbage and harmful garbage is small, the urgency of immediate treatment is not high, and wet garbage and dry garbage are not high, so the just-needed degree of the two garbage collection systems in residential areas is not high.

Action and Effect of the invention

Firstly, in the dry and wet garbage classification and collection system provided by the invention, the wet garbage and dry garbage throwing mechanism is arranged on the front end surface of the garbage collection box, and the garbage monitoring and collection mechanism is arranged in the garbage collection box. Not only effectively solved the shared proportion of dry rubbish and wet rubbish big, produced frequently high, the problem that the volume of empting is big, for the system that has set up four types of rubbish recovery unit, the flexibility is strong moreover, more accords with the in-service use demand, and manufacturing and use cost are also low.

Secondly, because the subsequent treatment processes of the dry garbage and the wet garbage are different, the treatment cost of the dry garbage per unit weight is higher than that of the wet garbage, and the subsequent treatment of the dry garbage and the wet garbage also has different requirements on the mixing degree. Based on the above, the mixed loading identification component is arranged in the wet garbage monitoring and collecting mechanism to monitor the mixing of the wet garbage, and the cost or other forms of calculation is carried out according to the weighing and mixing degree; the monitoring is not carried out in the dry garbage monitoring and collecting mechanism, the cost calculation is carried out only through weighing, and if other garbage is mixed into the dry garbage, the weight of the dry garbage can be greatly increased, so that the treatment cost is increased, and then residents are forced to classify.

On one hand, the design ensures the purity of the wet garbage from the source, and is beneficial to the smooth proceeding of the subsequent treatment; on the other hand, the technical support of garbage charging is realized, the promotion of the garbage classification consciousness is promoted from the source, and the manufacturing and using cost of the system is saved to the maximum extent.
