Description

Technical Field

[0001] This utility model relates to the field of activated carbon filters, and in particular to a granular activated carbon filter. Background Technology

[0002] An activated carbon filter is a device that uses the adsorption properties of activated carbon to purify harmful substances in water or air. Its principle is physical adsorption, and it is suitable for water purification, air purification, deodorization and other fields. Its advantages include effective removal of harmful substances, long service life, simple operation and convenient maintenance, and no secondary pollution.

[0003] When activated carbon filters process air, the air flows from bottom to top, first contacting the activated carbon particles at the bottom. This causes the activated carbon particles at the bottom to quickly reach saturation and become unable to adsorb further. Meanwhile, the activated carbon particles at the top have difficulty making direct contact with the air, resulting in poor air filtration. To address this, we propose a granular activated carbon filter. Utility Model Content

The support rod is fixedly installed on the upper surface of the drive motor, the connecting rod is fixedly installed on the lower surface of the support rod, the cleaning brush is fixedly installed on the upper surface of the connecting rod, and the propeller is sleeved on the upper surface of the support rod.
