Technical Field
[0001] This utility model belongs to the field of solid-liquid separation, and specifically relates to an inclined screen solid-liquid separator. Background Technology
[0002] A solid-liquid separator is a device used to efficiently separate solids and liquids in a mixture. It utilizes mechanical principles such as screw extrusion, centrifugal force, or sieving to achieve separation and is widely used in agriculture, industry, and environmental protection. In agriculture, it is commonly used for solid-liquid separation of livestock and poultry manure; the separated solid portion can be used as organic fertilizer, while the liquid portion can be used for irrigation or further treatment. In industry, it is suitable for solid-liquid separation in food processing and chemical production, such as separating fruit pomace from juice or treating chemical slurries. In the environmental field, it can be used for wastewater treatment to reduce the solid content in wastewater, thereby reducing the burden of subsequent treatment. This equipment is simple to operate, usually equipped with an automated system, and is often made of corrosion-resistant stainless steel to ensure durability and stability in complex environments. Furthermore, solid-liquid separators are available in various designs; users can choose from screw extrusion, centrifugal separation, or gravity screening types according to the material properties and processing requirements to meet the separation requirements of different application scenarios. They offer advantages such as environmental friendliness, high efficiency, energy saving, and durability.
[0003] However, some traditional screen cleaning devices have blind spots, and the accumulation of solid particles in the sewage can clog the screen. When the clogging is severe, the sewage overflows from the feed box and falls onto the platform, the ground, and the equipment, making it difficult to clean. The cleaning environment is poor, and the labor intensity for workers is high. In addition, excessive accumulation of sewage can affect surrounding equipment, making it difficult to clean and seriously damaging the equipment. Utility Model Content
