The thickener is a continuously working concentrating and clarifying device, is mainly used for dewatering fine ore and tailing slurry in wet-type mineral separation operation, and is also widely used for concentrating and purifying solid-containing slurry such as coal, steel, chemical engineering, building materials, water sources, sewage treatment and the like. When the common thickener works, pulp water is directly fed into the distributing device from the center of the tank through the feeding pipe.

The traditional distributing device is simple in distributing mode, the distributing barrel is only cylindrical in structure, and the diameter and the height of the distributing barrel are changed according to the diameter increase of the thickener. The thick liquids of traditional distributing device are given perpendicularly at the distributing device upper shed, because the coming material ore pulp directly rushes into thickener cloth section of thick bamboo, the ore pulp velocity of flow is very big, and the granule in the ore pulp can not fully precipitate, and the sedimentation layer of concentration tank bottom also can receive the destruction owing to receiving the impact of thick liquids. Thus not only influencing the concentration of overflow water at the upper part of the concentration tank, but also influencing the sedimentation effect of ore pulp particles at the middle lower part of the concentration tank. Meanwhile, common distributing devices are all non-adjustable, and have poor adaptability to slurry with different properties or different flow rates.
