Description

Technical Field

[0001] The utility model patent belongs to the technical field of phosphate mining equipment, and specifically relates to a muddy phosphate ore cleaning device. Background Art

[0002] Phosphate rock is a general term for phosphate minerals that can be used economically. It is an important chemical mineral raw material. In the process of phosphate mining, it is necessary to clean the soil attached to the raw phosphate ore. The traditional cleaning methods include: waterless screening or stirring and settling in water to separate the soil from the phosphate ore. However, waterless screening of phosphate ore can only remove the soil that has been separated from the phosphate ore, but cannot remove the soil wrapped on the surface of the phosphate ore. It is necessary to stir the phosphate ore to clean and remove the soil wrapped on the surface of the phosphate ore when it is precipitated in water, but the precipitated soil impurities are not easy to clean.

[0003] In the prior art, there is a muddy phosphate ore cleaning device disclosed in a Chinese patent (CN220295363U), which includes a processing shell and a cleaning mechanism, wherein both ends of the processing shell are fixedly connected and provided with end frames, and the cleaning mechanism includes a drum, an end pipe, and a metal round screen, wherein the drum is rotatably installed in the processing shell, the end pipe is fixedly installed at both ends of the drum, the end pipe is rotatably placed at the transition section of the end frame, the metal round screen is threadedly connected and installed on the inner circular wall of the end pipe, the outer end of the end frame is connected and fixedly installed with a circulation pipeline, and a circulation water pump is connected and fixedly installed in the circulation pipeline;

[0004] This design has the following defects:

[0005] 1. When loading the device, the drum needs to be lifted out of the processing shell, and the material needs to be fed outside the processing shell. After the feeding is completed, it needs to be lifted back into the processing shell, and the same applies to the unloading. The steps of loading and unloading are very cumbersome, which will reduce the cleaning efficiency;

[0006] 2. Filtration by the drum and filter mud box will easily cause blockage, affect water circulation, and increase the hydraulic pressure in the treatment shell, damage the working mechanisms in the treatment shell, and shorten its service life.

[0007] Therefore, this paper proposes a mud-containing phosphate ore cleaning device. Utility Model Content
