Kitchen waste recovery and treatment system

Abstract

The invention discloses a kitchen waste recovery and treatment system. The kitchen waste recovery and treatment system comprises a waste storage tank, a crusher, a screw press, a first dryer, a fertilizer storage tank, an oil-water separator, an oil storage tank, a conveying mechanism, a screw granulator and a second dryer, wherein a discharging hole of the waste storage tank is communicated with one end of the crusher through the conveying mechanism, the other end of the crusher is connected with a feeding hole of the screw press, a slag hole of the screw press is communicated with one end of the first dryer through the conveying mechanism, the other end of the first dryer is communicated with one end of the screw granulator through the conveying mechanism, the other end of the screw granulator is connected with one end of the second dryer, the other end of the second dryer is connected with the fertilizer storage tank, a filtering water outlet of the waste storage tank and an oil outlet hole of the screw press are connected with the oil-water separator through connecting pipes, and the oil-water separator is communicated with the oil storage tank through an oil pipe. An organic fertilizer prepared by recycling kitchen waste is high in quality.

Description

technical field [0001] The invention relates to a system for recycling and treating kitchen waste. Background technique [0002] With the rapid development of industry, the national income has gradually increased, the diet has become more and more abundant and abundant, and the amount of leftover food on the table has increased. [0003] Directly landfilling food waste will pollute soil and groundwater. Moreover, food waste contains a lot of water, which may cause water to flow out during transportation or landfill, and the outflowing water will smell bad, providing a habitat for pests or mice that may carry infectious bacteria, and causing serious damage to the surrounding environment. Pollution. [0004] If the food waste is incinerated, due to the high moisture content of the food waste, when it is incinerated with other domestic waste, toxic dioxin gas will be produced. [0005] A comprehensive food waste treatment system has appeared on the market, including a feedin...

Problems solved by technology

However, the pulverizing and extruding solid-liquid separation device in this food waste comprehensive treatment system first pulverizes the food waste and then performs solid-liquid separation. After the pulverization, the fertilizer nutrients will flow out with the liquid, resulting in the loss of The quality is reduced, and due to the high water content of kitchen waste, the efficiency of solid-liquid separation at one time is not high, which will increase the energy consumption of the solid hot air drying device
