The invention relates to an independent dedusting system of a material bin. A plurality of material bins share one air ventilation main pipeline. Each material bin comprises a feeding port and a dedusting box check port, the feeding port of each material bin is positioned at the top part of the material bin and is sealed by a material bin door, and a proximity switch is arranged on each material bin door; the side surface of each material bin is provided with an opening, and a box body of a dedusting box penetrates through the opening, and is arranged in the corresponding material bin through a flange; a filter plate is arranged at one end, near the interior of the material bin, of each dedusting box, and a connecting flexible pipe is arranged at one end, away from the interior of the material bin, of each dedusting box; the connecting flexible pipes of the multiple material bins are connected with the air ventilation main pipeline; an air ventilating valve is arranged on each connecting flexible pipe; a pulse valve is arranged on the box body of each dedusting box besides the corresponding connecting flexible pipe; the tail end of the air ventilation main pipeline is connected with a high pressure fan, and an ECU (electronic control unit) is arranged on the high pressure fan and is used for controlling the high pressure fan to run. The independent dedusting system has the advantages that the occupation of installation space at the exterior of the material bin is reduced, and the independent dedusting system is suitable for installing in narrower installation space.
