Description

technical field [0001] The invention relates to an electrolytic filter press dehydration device for fine coal, belonging to the technical field of electrochemical treatment of fine coal and design and manufacture of filter press dewatering equipment. Background technique [0002] Fine-grained coal is the main product of mechanized coal mining. The higher the degree of mechanization of mining, the higher the yield of fine-grained coal. [0003] The particle diameter of fine-grained coal is mostly less than 0.5mm, with high ash content, high viscosity and high moisture content, which brings great disadvantages to the application, transportation and storage of coal. In order to make fine-grained coal more widely used and convenient for storage and transportation, Therefore, fine-grained coal must be treated in advance, mainly dehydration treatment. Suction filtration and pressure filtration are often used for dehydration treatment. , with the current dehydration equipment and ...

AI Technical Summary

Problems solved by technology

[0004] Most of the fine-grained coal dehydration equipment currently used is relatively backward. For example, the suction filter can only remove part of the water on the surface due to the small suction force, and cannot remove the internal water in the fine-grained coal, so the dehydration rate is very low; for example Ordinary filter presses, although improved compared with suction filtration, have a greater squeezing force, and although they are better at removing surface moisture, they have little effect on fine-grained coal internal water, or even cannot remove it; none of the current dehydration equipment can Meet the dehydration needs of fine coal
