Description

Technical Field

[0001] The utility model relates to the technical field of clean coal processing equipment, in particular to a clean coal dehydration and ash reduction device. Background Art

[0002] Clean coal is produced by washing raw coal and removing gangue from it. After washing, the clean coal needs to be placed in a dehydration and ash removal device to dehydrate it and prevent the ash produced by dehydration from drifting outside the device.

[0003] For example, the utility model: "A clean coal dehydration and ash reduction device", with the announcement number: "CN219160831U", installs a dehydration mechanism, so that the clean coal dehydration and ash reduction equipment can greatly reduce the dust raised in the air during the dehydration of the clean coal, making the clean coal dehydration work simpler and safer. However, during the implementation of the patent, the sieve plate inside the barrel will continuously stir and turn the clean coal to prevent the dust from flying out, but the device cannot collect the coal ash that has been generated, so that the coal ash is still mixed in the clean coal. When taking out the dehydrated clean coal, the coal ash is still easy to be raised and drift to the outside. Therefore, the research and development of new clean coal dehydration and ash reduction devices has received more and more attention from researchers. Utility Model Content
