Abstract
The invention discloses a liquid-solid fluidization separation system. The liquid-solid fluidization separation system comprises a bed body which is arranged in an inclined way, wherein a water outlet pipe and a water inlet pipe are arranged on the top and at the bottom of the bed body respectively; a discharge port and a feed port are formed on the bed body on the lower side of the water outlet pipe and on the bed body on the upper side of the water inlet pipe respectively; the diameter of the bed body gradually becomes larger from the bottom up; a water power distributing plate is arranged inside the bed body between the water inlet pipe and the feed port; a plurality of through holes are uniformly distributed on the water power distributing plate; and a fluid pipe is arranged on a downwards inclining wall surface of the bed body between the discharge port and the feed port. Due to diameter-variable design of the bed body, the flow rate of water gradually decreases along with the increase of the pipe diameter, and grains are always in a speed-variable motion state in a diameter-variable and speed-variable flow field, so that a wide-grain size multi-component material can be effectively separated according to the density; and through introduction of air flow or water flow into a separation device, the material accumulating on the wall surface looses again along with the air flow and reenters the diameter-variable and speed-variable flow field for secondary separation, thus greatly improving the separation effect.
