Description

technical field [0001] The invention relates to the technical field of garbage pretreatment, more specifically, to a domestic garbage pretreatment device and a pretreatment method thereof. Background technique [0002] With the improvement of my country's economic strength, people's living standards continue to improve, and the domestic waste generated by households and catering industries has also increased. At present, the amount of domestic waste generated has a geometric growth trend compared with decades ago. A large amount of domestic waste The emergence of the environment will inevitably bring great harm to the environment. However, my country's domestic waste treatment industry is in its infancy, and the method of anaerobic fermentation capacity treatment is one of the key points of future development. This technology is an advanced treatment of domestic waste. And now there are mature technological processes and schemes, but this technology has high requirements for t...

[0002] With the improvement of my country's economic strength, people's living standards continue to improve, and the domestic waste generated by households and catering industries has also increased. At present, the amount of domestic waste generated has a geometric growth trend compared with decades ago. A large amount of domestic waste The emergence of the environment will inevitably bring great harm to the environment. However, my country's domestic waste treatment industry is in its infancy, and the method of anaerobic fermentation capacity treatment is one of the key points of future development. This technology is an advanced treatment of domestic waste. And now there are mature technological processes and schemes, but this technology has high requirements for the pretreatment of domestic waste. The technical methods and equipment for the pretreatment of domestic waste mainly focus on solid-liquid separation, oil-water separation, and the collection of stench Gas, the effect of pretreatment directly affects the effect of subsequent anaerobic production capacity and the impact on the environment. Most of the existing domestic waste pretreatment methods and equipment are located in waste treatment plants or landfills, and their characteristics are basically Large-scale, energy-intensive and centralized processing

[0003] In the prior art, the pretreatment of domestic waste requires processing steps such as crushing, drying, and solid-liquid separation. However, there is no equipment in the prior art that can simultaneously achieve crushing, drying, and solid-liquid separation, and the above-mentioned The processing steps are combined, which is time-consuming and labor-intensive
