The utility model relates to a thickener for slime water, which mostly uses a deep cone thickener during the thickening of the slime water, wherein the deep cone thickener is a machine body with a cylindrical upper part and a conical lower part. As the name implies, its cone is deep. The working principle of the deep cone thickener is that under the condition of adding flocculating agent, flotation tailing is sent into a feeding barrel with a cone-shaped distribution opening at the lower part. Most water in the coal slime water flows to the periphery in a clarification area of a cylindrical part of the thickener and overflows, and a small part of water forms a small vortex in a floc settling area. In the conical part of the machine body, i.e. the compression zone, the sediment is compressed under the action of gravity and is discharged from the bottom flow port or pumped out by a pump. The diameter of the deep cone thickener is 6-l 0m, the height of the cylindrical part is 6-7 m, and the height of the conical part is 7.8 m. The cone of the deep cone thickener is thicker, and the bottom of the sediment cone bears the action of large gravity compression, so that the solid content of the bottom flow is very high. According to the different characteristics of the tail coal and the discharge amount of the underflow, the solid content of the underflow is between 200 and 800 g/l. If the flocculated sediment is slightly stirred, the compression degree of the flocculated sediment is higher, so that the cone storing part of some deep cone thickeners is provided with a stirring device to facilitate the continuous dewatering of the sediment.
Because the thick mobility of concentrator lower extreme deposit is relatively poor, lead to the jam of discharge gate position easily, influence row material, and this kind of concentrator of current mostly does not have and can see inside deposit and the mixed condition downwards in the condition that does not influence its normal use.
