Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in the figure, a nitrogen making adsorption cylinder comprises a cylinder body 1, wherein a material pressing component and an air inlet pipe component 2 are arranged at the upper end of the cylinder body 1, the material pressing component is located at the upper end of the air inlet pipe component 2, and an air outlet pipe component 3 is arranged at the lower end of the cylinder body 1. The top of the cylinder body 1 is fixedly connected with a third flange 8, and the upper end of the third flange 8 is connected with a flange cover 9 through bolts. The bottom of the barrel 1 is provided with a support frame 7 for supporting.

The material pressing assembly comprises a piston plate 4 in up-down sliding fit with the interior of the barrel body 1, an elastic element arranged between the piston plate 4 and the flange cover 9 and a palm cushion layer 5 bonded to the bottom of the piston plate 4, wherein the elastic element is specifically a plurality of springs 6. The material pressing component plays a role in compressing the molecular sieve.

The air inlet pipe assembly 2 comprises an air inlet pipe 20, a plurality of first through grooves 200 are formed in the pipe wall of one end, located in the cylinder body 1, of the air inlet pipe 20 in an annular mode, a first sealing plate 21 is fixedly connected to the end, located at the end of the air inlet pipe 20, of the air inlet pipe, and a first mesh screen 22 used for covering the first through grooves 200 is sleeved outside the air inlet pipe 20. One end of the air inlet pipe 20 extending out of the cylinder 1 is fixedly connected with a first flange 23. The first through grooves 200 serve to make the gas diffused more uniformly when passing into the drum 1.

The air outlet pipe assembly 3 comprises an air outlet pipe 30, the air outlet pipe 30 is a U-shaped pipe fitting, a plurality of second through grooves 300 are formed in the pipe wall of one end, located in the barrel body 1, of the air outlet pipe 30 in a surrounding mode, a second sealing plate 31 is arranged at the end, located at the end of the air outlet pipe 30, of the pipe wall, and a second mesh screen 32 used for covering the second through grooves 300 is sleeved outside the air outlet pipe 30.
