Description

Hydraulic automatic solid dewatering machine

Technical Field

The invention relates to a material dehydration device, in particular to a hydraulic automatic solid dehydration machine.

Background

The microbial organic fertilizer is an organic fertilizer or an organic microbial coated fertilizer which is processed by microbial fermentation, deodorization and complete decomposition of organic solid wastes including organic garbage, straws, livestock and poultry manure, cake meal, agricultural and sideline products and solid wastes generated by food processing.

In the production process of the microbial organic fertilizer, materials including organic solid wastes and products obtained after the organic solid wastes are processed need to be dried. At present, the drying and dehydration are generally carried out by a screw extrusion dehydration method, a drying and drying method or a chemical dehumidification method. The screw extrusion dehydration method is mainly used for dehydrating the livestock manure, but has high energy consumption, and the dehydrated material has high water content and poor dehydration effect. The drying and drying method is to heat the material by heated air, gasify the moisture in the material to form water vapor, and bring the water vapor out of the dryer with the air, and the drying and drying method has good dehydration effect, but large energy consumption and high cost. The chemical dehumidification method is to use a desiccant to remove a small amount of moisture in gas, liquid and solid materials, but because the dehumidification capability of the desiccant is limited, the chemical dehumidification method is only used for removing a small amount of moisture in materials at present, and is rarely applied in actual production.
