The suspension enters the drum from the screw outlet through the feed pipe. Under the centrifugal force generated by high-speed rotation, solid particles with high specific gravity are deposited on the inner wall of the drum, and the spiral blades moving relative to the drum constantly scrape off the solid particles deposited on the inner wall of the drum and push them out of the slag discharge port. The separated clear liquid overflows from the drum through the opening of the liquid layer adjusting plate. The relative motion (i.e. differential rotation) between the screw and the drum is realized by the differential, and its size is controlled by the auxiliary motor, thus realizing the continuous separation process of materials by the centrifuge.
Performance characteristics of coal washing sewage desliming centrifuge: the main components are made of high-quality carbon steel or stainless steel. The push rod adopts special wear-resistant measures, and can be inlaid with cemented carbide wear-resistant tiles or hardfaced with cemented carbide protective layers. Adopt cycloidal pin-wheel differential, with low noise and strong bearing capacity. The single machine has compact structure, covers an area of 2-3 square meters, and runs smoothly. It can be unloaded automatically and run continuously. Workers only need to operate the power cabinet, which is clean and hygienic. It has wide adaptability to materials, and the particle size range of separable solid phase is wide (0.005~2mm). When the solid particles are not uniform in size, they can be separated as usual. The dosing situation depends on the material, and generally no dosing is needed, which saves the cost. According to the materials selected by the industry, 304, 365 and 438+06 stainless steel can be selected for centrifuges, and explosion-proof motors can be used in special industries.
This kind of equipment mainly separates solids from liquids, commonly known as solid-liquid separation equipment (centrifugal dehydrator, horizontal spiral centrifuge).
