Description

Organic biological garbage treatment process system

Technical Field

The specification relates to the technical field of garbage treatment, in particular to an organic biological garbage treatment process system.

Background

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

The kitchen waste is one kind of organic biological waste. In the prior art, a shear type pulverizer and a biological squeezer are generally needed for treating the kitchen waste. Specifically, a shear type grinder is adopted to grind the kitchen waste, so that corresponding materials are prepared for the subsequent hydraulic pressing link. And pumping the crushed materials to a biological squeezer for solid-liquid separation. The kitchen waste is extruded into slurry by utilizing high-pressure power of a hydraulic station, and a liquid phase part and a solid phase part are separated. In order to extract organic matters to the maximum extent, the solid phase part separated by pressing can be pressed for the second time.

Along with the complication of urban kitchen waste, the shear type pulverizer of the original process can not meet the kitchen waste of light objects including more plastic bags and the like gradually, and the winding problem of cutting the light objects can be serious gradually after the shear type pulverizer runs for a long time. And most shearing crushers have the defects of large volume, high price, high energy consumption and the like because the shearing crushers are commonly used in the industries of mines, construction waste and the like.

The biological squeezer has unique advantages in treating completely crushed materials, but various problems are easy to occur in a hydraulic system under the corrosion of kitchen waste due to the adoption of a hydraulic driving mode. And because the pressure of the biological squeezer is higher, the equipment loss is also more serious, and the power consumption is high.
