System for preparing organic fertilizer from wet garbage

Abstract

The invention discloses a system for preparing an organic fertilizer from wet garbage. The system comprises a garbage sorter, a crusher, an extruding dewatering device, a garbage lifting device, a liquid collector, a liquid pump, an oil-water separator, an oil collecting vessel, a sewage treater, a degrader, a closed type degraded material conveyor, a degraded material concentrator, a powder material dryer and a bagger, wherein the garbage sorter is used for picking out metallic materials from kitchen garbage, the sorted kitchen garbage is crushed by the crusher and is fed to the extruding dewatering device, the garbage dewatered by the extruding dewatering device is fed to a charging opening of the degrader by using the garbage lifting device, and liquid extruded by the extruding dewatering device and liquid draining from the garbage sorter flow into the liquid collector. Oil and salts of the garbage are separated in a crushing and extruding dewatering deoiling manner prior to degradation, so that the improvement on activity of organisms is facilitated, and thus, the efficiency of degradation is increased.

Description

technical field [0001] The invention relates to a meal waste treatment device, in particular to a system for preparing organic fertilizer from wet waste. Background technique [0002] Meal waste refers to food waste, catering leftovers, food processing waste and non-edible animal and vegetable oils and various oil-water mixtures from families, schools, institutions, public canteens and catering industries. It is a part of urban domestic waste. It occupies a high proportion in domestic waste. At present, the main methods of food waste treatment in my country are as follows: 1. Crushing and direct discharge treatment: crushing and direct discharge treatment is the main method for processing a small amount of scattered food waste in European and American countries, and it is directly crushed at the point where food waste occurs , Crushing treatment, and then use hydraulic flushing, discharge it into the urban municipal sewer network, merge with urban sewage into the urban sewag...

AI Technical Summary

Problems solved by technology

The technical solution of the above-mentioned patent only has a humidity detector, but does not have the technical content of adjusting the humidity of the air

And the waste heat is not recycled, so it is not energy-saving and environmentally friendly.

[0004] The existing degrading machine does not deoil and desalt before degrading the garbage, so it is not conducive to the survival of microorganisms, making the activity of microorganisms low, thus affecting the degradation efficiency
