1. Application field
It has been widely used in chemical, pharmaceutical, food, light industry, papermaking, mining other industrial sectors. Such as the dehydration of calcium carbonate, calcium bicarbonate, polyvinyl chloride, polypropylene, soybean peanut protein, dehydration of corn alcohol grains, separation of calcium hypochlorite, classification of titanium dioxide, starch concentration classification, drilling sludge, papermaking wastewater Treatment, municipal sewage treatment, tar deslagging, three-phase separation of coal tar, etc.
The horizontal spiral unloading sedimentation centrifuge is a continuous operation centrifuge that uses the sedimentation principle to separate the suspension. It can continuously feed, sediment, dehydrate when running at full speed.
2. Main features of centrifuge
●Good corrosion resistance: According to the different materials used, the materials in contact with the materials are 304 , 316L , 904L , 926､C276､Ta2, etc.
●Good wear resistance: The spiral blade adopts surfacing welding tungsten carbide cemented carbide, spray welding tungsten carbide cemented carbide, bonded ceramic sheet, etc., the discharge port uses ceramic cemented carbide nesting.
●Differential speed control: Through frequency conversion PLC control, it can meet the control requirements of different materials different working conditions for the differential speed between the screw the drum.
●Perfect after-sales service: The horizontal spiral unloading sedimentation centrifuge with multiple specifications, multiple cone angles, multiple length-to-diameter ratios meets the needs of various materials separation, the laboratory can conduct material selection tests.
Three, working principle
The suspension enters the full-speed rotating drum the feed pipe in the middle. Due to the centrifugal force field, the denser sediment (heavy phase) in the suspension is deposited on the inner wall of the drum, while the less dense clarified liquid (Light phase) is in the inner part of the sedimentary layer. The sludge is conveyed by the screw to the cone section of the drum discharged through the sludge discharge port, the clarified liquid flows through the spiral channel formed by the spiral blades to the column section of the drum overflows the overflow port, thereby realizing the liquid-solid two with different density. Phase separation.
