Abstract
The invention provides a spiral conveying assembly and solid-liquid separation equipment, the spiral conveying assembly comprises a rotating shaft and a spiral blade assembly, the rotating shaft is a hollow shaft and is internally provided with a water collecting cavity, and the shaft wall of the rotating shaft is provided with a drainage hole communicated with the water collecting cavity; the spiral blade assembly comprises a hollow blade, a plurality of mounting holes are formed in the hollow blade in the material conveying direction, the mounting holes communicate with an inner cavity of the hollow blade, and a plurality of water through holes are formed in the rotating shaft and used for communicating the inner cavity with the water collecting cavity; the spiral conveying assembly further comprises a plurality of filtering assemblies, the filtering assemblies are arranged in the mounting holes, and a plurality of filtering channels communicating with the inner cavity and the external environment are formed in the filtering assemblies; by the adoption of the technical scheme, the spiral blades are matched with the rotating shaft, the functions of material conveying and solid-liquid separation are achieved at the same time, then the solid-liquid separation efficiency of materials can be effectively improved, and the solid-liquid separation equipment comprises the spiral conveying assembly.
Description
technical field [0001] The invention relates to the field of solid-liquid separation equipment, in particular to a screw conveying component and solid-liquid separation equipment. Background technique [0002] The existing auger-type solid-liquid separation equipment is suitable for the excrement treatment of various farmed livestock and poultry, and its structure usually includes a shell, a separating screen, an auger and other parts. There are still many problems in the current solid-liquid separation equipment, such as the adaptability to materials and the efficiency of solid-liquid separation. In particular, improving the separation efficiency has always been the research goal of relevant technical personnel. [0003] At present, the optimization and improvement schemes for solid-liquid separation equipment generally focus on the research and improvement of the auger. For example, in the document with the application number CN201921573628.5, the blades of the auger are ...
