Description

Technical Field

[0001] The utility model belongs to the technical field of garbage treatment, and particularly relates to a harmless treatment device for domestic garbage. Background Art

[0002] With the development of social economy, people's lives are becoming more and more abundant. Correspondingly, more domestic garbage is generated, mainly including kitchen waste (wet garbage), solid waste (dry garbage), etc. In the prior art, the above two types of garbage are treated separately. For kitchen waste, usually food waste, its composition is complex, including oil, water, fruit peels, vegetables, rice, noodles, fish, meat, bones, etc. Currently, common treatment methods include landfill, incineration, anaerobic digestion, aerobic composting, drying for feed or microbial treatment, etc. For solid waste, methods such as crushing, landfill, incineration, pyrolysis gasification, etc. are usually used. Among them, for wet and dry garbage, incineration and carbonization treatment after drying and dehydration are feasible.

[0003] However, in the current technology, for domestic garbage, it is divided into dry garbage and wet garbage, and carbonization treatment is carried out separately and independently. And manual intervention is required in each link of the treatment process. It is not and cannot be fully automated, and the information record of the working process is incomplete. In case of a malfunction, it is also very difficult to locate, which brings great inconvenience to the staff.

[0004] Therefore, the prior art still needs to be further improved and enhanced.

[0005] Chinese Patent with publication number CN211679270U and publication date October 16, 2020 discloses an integrated domestic garbage carbonization treatment device, which includes a cabinet. At least two feeding boxes opening on the cabinet for receiving the input of domestic garbage are arranged in the cabinet: a kitchen waste feeding box for accommodating kitchen waste and a solid waste feeding box for accommodating solid waste; the feeding boxes are respectively connected to corresponding garbage crushing boxes for crushing garbage: a kitchen waste crushing box and a solid waste crushing box; the outlet of the kitchen waste crushing box is connected to a material distribution valve. The material distribution valve includes an inner discharge position. When the material distribution valve is in the inner discharge position, it is connected to a silo through a suction hopper. A suction fan is arranged downstream of the silo for sucking the crushed kitchen waste into the silo and then carrying out corresponding carbonization processes. After carbonization into carbon powder, it is discharged outwards; the outlet of the solid waste crushing box is connected to a garbage bin through a material distribution screw; it also includes a control system for controlling the flow direction of domestic garbage by controlling each control switch. The control switch includes a material distribution switch for controlling the staying position of the material distribution valve. This device has the disadvantage of complex structure.
