Existing solid-liquid separation devices for kitchen waste have a lot of residual liquid after spiral dewatering, resulting in poor liquid separation effect and affecting dewatering efficiency and solid-liquid separation efficiency.
The solid and liquid waste is initially crushed by a crushing roller device, then conveyed to the first discharge channel by a screw extruder for the first filtration. Next, it undergoes a second filtration through a discharge square pipe and the first filtration device, followed by a second filtration through a drain hole, and finally a third filtration through a second filtration assembly. The solid waste then enters the main collection pool.
It significantly improves liquid separation and dehydration efficiency, prevents clogging of the discharge pipe, and ensures efficient solid-liquid separation.

[0002] Due to dietary culture and dining habits, food waste has become a unique phenomenon in China. Food waste at Chinese tables is staggering, generating massive amounts of food waste daily. Food waste mainly consists of solid organic matter and swill containing oil, and is prone to spoilage and decay. Improper disposal can cause environmental and health hazards, necessitating purification treatment. Before treatment, food waste needs solid-liquid separation, requiring the use of food waste solid-liquid separation devices.
[0003] In related technologies, the solid-liquid separation and dehydration device for kitchen waste is an important piece of equipment for treating kitchen waste. Its main function is to separate the solid and liquid parts of kitchen waste and achieve the purpose of dehydration. The main purpose of solid-liquid separation is to distinguish between solid waste and liquid waste. Solid waste is used for recycling and processing into fertilizer, while liquid waste is used for recycling and processing into fuel oil.
