Description

A garbage storage device for a closed garbage collection system

technical field

The utility model relates to the technical field of garbage collection, in particular to a garbage storage device used in a closed garbage collection system.

Background technique

The traditional method of manual garbage collection is: a trash can is placed in the elevator room or corridor passage of each floor for residents to put in garbage, and the garbage is temporarily stored in this trash can until the sanitation workers come to collect and transport the garbage away; in some In old towns or streets, some garbage carts or large garbage bins are used to load garbage, which not only causes a strong odor around, seriously pollutes the surrounding air, but also requires sanitation workers to collect the garbage together again and transport it to the garbage Centralized processing center. These traditional methods of manually collecting garbage are not only time-consuming and labor-intensive, but also cause secondary pollution of garbage.

In response to the above problems, the Chinese invention patent discloses a closed automatic garbage collection system and its control method with the patent number CN101712400A, which includes garbage dispensing equipment, conveying pipelines, central collection equipment, control centers and negative pressure power source devices. The conveying pipeline Connect the garbage dispensing equipment with the central collection equipment, and the control center controls the negative pressure power source device to form the required negative pressure in the conveying pipeline. The garbage dispensing equipment includes garbage dispensing ports, storage nodes, discharge valves and air intake valves There is a discharge valve connected under the above-mentioned storage section; although this system overcomes the defects of the above-mentioned traditional manual garbage collection, it is easy to deposit residual liquid such as kitchen soup and other garbage in the storage section, and it will emit an unpleasant odor after decay (the main The composition is methane), if the garbage residual liquid is not discharged in time, the methane content in the storage section will accumulate higher and higher. When the methane content reaches 5-15.4%, once someone throws an open flame such as an unextinguished cigarette butt into the storage section It will immediately cause a violent explosion, which poses a great safety hazard; in addition, more and more garbage is piled up in the storage section, and the garbage at the bottom layer is piled up into blocks, which is not conducive to being sucked and transferred to the central collection equipment.
