Description

Technical Field

[0001] This invention relates to the field of mining technology, and more specifically to a mining mud separation device. Background Technology

[0002] Mining operations generate a large amount of mud.

[0003] These muds contain useful mineral particles and a large amount of water. In order to achieve effective recycling of resources and reduce environmental pollution, mining muds need to be separated into wet and dry parts.

[0004] Existing mining mud separation equipment suffers from problems such as low separation efficiency and poor separation effect, making it difficult to meet the actual production needs for efficient and multi-stage mud separation.

[0005] Some traditional separation devices have inadequate structural designs, failing to achieve sufficient filtration of mud and effective separation of liquid and solid. This results in mud still containing a significant amount of water after separation, or liquid containing a large amount of solid impurities, reducing resource recovery rate and utilization value.

[0006] Therefore, developing a mining mud separation device that can achieve efficient, multi-stage dry-wet separation is of great practical significance. Summary of the Invention

The filtered liquid drips into the second collection tank 504 for storage. When the mud slides to the low end of the second filter channel 313, it enters the first collection tank 502 through the outer cylinder first outlet 303, thereby achieving efficient and multi-stage dry and wet separation of the mud.
