Description

Technical Field

[0001] The utility model belongs to the field of garbage processing equipment, in particular to an organic garbage processing equipment. Background Art

[0002] Aerobic fermentation fertilizer making process projects mostly use biochemical machine aerobic fermentation fertilizer making technology. This technology not only saves space by performing aerobic fermentation in the machine, but also better controls secondary pollution such as sewage and odor. Therefore, this technology has been increasingly used in garbage treatment equipment. However, this type of equipment currently has the following main problems:

[0003] For example, the invention patent application with Chinese patent publication number CN105080945A discloses a household organic waste treatment process system, which creates a suitable fermentation environment by adding a chopping device, a stirring device, a fermentation cylinder, a liquid crystal display screen and multiple sensors to quickly and efficiently decompose and treat organic waste. However, the process does not involve oil-water separation, and does not fully utilize the existing by-products after oil-water separation.

[0004] For example, the invention patent application with Chinese patent publication number CN116765093A discloses a garbage treatment device and its use method and a garbage treatment process. By setting a bag breaking device, a cleaning drum, a dehydrator, a shredder, and an extrusion box, it is possible to facilitate the extrusion of materials and control the size of the extruded materials for easy transportation and use. However, the process only simply compresses the garbage into solids and does not apply more efficient methods of garbage treatment such as aerobic fermentation and anaerobic fermentation.

[0005] For example, the invention patent application with Chinese patent publication number CN116765093A discloses a high-temperature rapid composting device, which arranges an inner rotating drum and inner and outer heating drums in the tank body, and the sludge in the tank body is all involved in the circulation when the stirring shaft rotates, which can quickly react with the temperature to achieve the purpose of high-temperature rapid composting. However, this process does not involve the crushing of the garbage, so additional pretreatment of large volumes of solid garbage is required.

[0006] In summary, there is an urgent need for an organic waste treatment device with comprehensive functional effects. Utility Model Content
