[0035] A ventilation grid plate 20 is fixedly mounted on the other side of the housing 1 .

[0036] The working principle of the adsorption cylinder gas distributor for air separation equipment provided by the utility model is as follows:

[0037] The first step: first, the air to be separated is transported into the device through the air inlet pipe 18 and the air inlet nozzle 19 by an external fan. The air is blocked when passing through the metal perforated plate 2 and the filter medium 4, and can only move forward through the medium gap, thereby distributing the air. The filter medium 4 will perform preliminary filtration on the air. The distributed air continues to move forward, and passes through the dust filtering mechanism. With the cooperation of the dust removal keel 9 and the dust removal bag 10, the dust in the air is intercepted and filtered by the dust removal bag 10, so that the air can be further separated later.

[0038] The second step: when there are different separation requirements, by pulling the fixed block 2 15, the limiting rod 13 is driven to retract, thereby releasing the limit on the handle 6, and then pulling the handle 6 to drive the rotating drum 5 to rotate, so that the corresponding through hole 2 is aligned with the corresponding through hole 1 below the sleeve 3, and the filter medium 4 in the sleeve 3 is discharged, and then the rotating drum 5 is rotated to align the corresponding through hole 2 with the corresponding through hole 1 above the sleeve 3, and the new filter medium 4 is injected from the through hole 1. After the injection is completed, the fixed block 2 15 is pulled to drive the limiting rod 13 to retract, and the rotating drum 5 is rotated back to its original position, and the fixed block 2 15 is released. Under the action of the spring 1 131, the two limiting rods 13 pop out again to lock the rotating drum 5;

[0039] The third step: when the dust bag 10 needs to be cleaned, pull the two L-shaped latches 16 on the shell 1 to release the limit on the two arc-shaped cover plates 11, open the two arc-shaped cover plates 11, take out the fixing plate 7 together with multiple dust keels 9 and multiple dust bags 10, and replace the old dust keels 9 and dust bags 10 with new dust keels 9 and dust bags 10, then put the fixing plate 7 back along the arc groove, and pull the two L-shaped latches 16 again to reset the two arc-shaped cover plates 11, release the two L-shaped latches 16, and under the action of the two springs 161, the two L-shaped latches 16 pop out to limit the two arc-shaped cover plates 11 again.
