Description

Technical Field

[0001] The utility model relates to the technical field of deep cone concentrators, in particular to a dehydration device of a deep cone concentrator. Background Art

[0002] The deep-cone thickener features a cylindrical upper section and a conical lower section. As the name suggests, the cone is relatively deep. The deep-cone thickener operates by feeding flocculants into a feed drum with a conical distribution port at the bottom. Most of the slurry flows out of the clarification zone in the cylindrical section of the thickener, while a small amount forms small vortices in the floc settling zone. In the conical section of the thickener, or compression zone, the sediment is compressed by gravity and discharged through an underflow port or pumped out. The diameter of the deep cone concentrator is 6 to 10 meters, the cylindrical part is 6 to 7 meters high, and the conical part is 7.8 meters high. The cone of the deep cone concentrator is relatively dense, and the sediment stored at the bottom of the cone is subjected to a large gravity compression, which makes the solid content of the bottom flow very high. Depending on the characteristics of the tail coal and the amount of bottom flow discharge, the solid content of the bottom flow is between 200 and 800 g / l. If the flocculated sediment is slightly stirred, the degree of compression will be higher. Therefore, some deep cone concentrators are equipped with a stirring device in the cone part to facilitate the continued dehydration of the sediment.

[0003] For example, a high-efficiency deep cone sludge thickening device with announcement number CN 10378519A and announcement date 2014.05.14 includes a deep cone sedimentation tank barrel, an upper inclined cone, a lower inclined cone, a deep cone sedimentation tank cone, a deep cone sedimentation tank discharge barrel, a deep cone sedimentation tank discharge port, a deep cone sedimentation tank overflow port, a deep cone sedimentation tank feed port, a deep cone sedimentation tank flocculant feed port, a static mixer, a stirring device, a deep cone sedimentation tank feed barrel, a feed barrel baffle and other components.

[0004] As mentioned above and in the prior art, when the flocculant and sludge water are stirred, they can only be stirred horizontally and the sludge at the bottom cannot be lifted upward, resulting in poor mixing effect of the flocculant and the sludge at the bottom of the deep cone concentrator, and thus the impurities in the sludge water cannot be fully flocculated. Therefore, it is urgent to design a dehydration device for the deep cone concentrator to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a dehydration device for a deep cone concentrator to solve the above-mentioned deficiencies in the prior art.
