Although the theoretical maximum concentration of molecular sieve oxygen production is only 96%, which is lower than that of water electrolysis oxygen production and cryogenic oxygen production (mainly used for large-scale industrial oxygen production), its equipment is simple, safe, and the oxygen production concentration can meet most clinical oxygen needs.

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0038] First, the staff moves the circulating conversion adsorption oxygen generator to the place where it is needed, then connects the external power supply, starts and debugs the circulating conversion adsorption oxygen generator, and then injects air into the feeding system 1 through the external pipe. Then the air passes through the paving system 2 and enters the transfer system 3. The three layers of carbon particles in the transfer system 3 adsorb the oxygen in the air inside the carbon particles. Due to the distribution position of the carbon particles, the concentration of oxygen adsorbed by the carbon particles in the bottom layer is higher than that in the upper two layers. When the carbon particles in the bottom layer reach saturation, the transfer system 3 is controlled to transfer the carbon particles in the bottom layer to the paving system 2, and at the same time, the carbon particles in the upper two layers are lowered by one layer, and then the paving system 2 is controlled to transfer the carbon particles scattered above it, and at the same time, the upper two layers of carbon particles are controlled to move. The feeding system 1 cooperates to transfer the saturated carbon particles to the top layer of the transfer system 3; during this process, the transfer system 3 is controlled to organize some of the scattered carbon particles, and then the air is continued to work. When the three layers of carbon particles are all saturated, the transfer system 3 is controlled to transfer the carbon particles in the bottom layer to the paving system 2, and then the paving system 2 is controlled to pave the carbon particles, and then the gas inside is extracted through an external vacuum pump to make the feeding system 1 reach a vacuum state, and then the oxygen adsorbed in the carbon particles in the bottom layer is extracted, and then the paving system 2 is controlled to cooperate with the feeding system 1 to transfer the carbon particles to the top layer of the transfer system 3, and then the oxygen in the three layers of carbon particles is completely extracted in the same way, so that the carbon particles can continue to work.

[0046] The third discharging track 302 is arranged in an inverted V shape for guiding the carbon particles.

[0047] The fourth discharging track 304 is configured in a V-shape to guide the carbon particles.

[0048] The overall configuration of the discharge pipe 3013 is a hollow rectangular tube to avoid the inability to collect the carbon particles scattered during the transfer due to the lower part being filled up.

[0049] First, the staff uses an external tube to inject air into the material tank 102 through the two air inlet pipes 103, and then the air moves upward and moves to the bottom of the transfer system 3 through the paving system 2. When it continues to move upward, since the carbon particles fill the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307, the carbon particles in the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307 at the bottom absorb most of the oxygen in the air. Then the air continues to move upward, and then the carbon particles in the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307 in the middle continue to absorb part of the oxygen. Then the air continues to move upward, and the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307 at the top absorb part of the oxygen. 6 and the carbon particles in the fourth grid plate 307 absorb the remaining oxygen, and then the carbon particles that have completed the adsorption of air are discharged through the outlet pipe 108. When the carbon particles in the bottom layer are saturated with adsorption, for the convenience of description, the description of the transfer system 3 is described by taking the transfer component of the top layer as an example, and the working principles of the other two layers are the same. When the carbon particles are saturated with adsorption, the two electric push rods 3014 are controlled to push the limit plate 3015 to move downward, and the limit plate 3015 moves downward to form a gap between the two fourth grid plates 307. Then the carbon particles in the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307 flow downward from the gap between the two fourth grid plates 307 to the fourth discharge track 304 below. The four discharge tracks 304 are arranged in a V shape, and the carbon particles on the fourth discharge track 304 gather in the middle of the fourth discharge track 304, and fall into the third discharge track 302 through the through groove in the middle of the fourth discharge track 304. Since the third discharge track 302 is arranged in an inverted V shape, the carbon particles are diverted along the two oblique sides of the third discharge track 302, and flow into the inclined space formed by the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307. In the process of flow transfer, part of the carbon particles will fall onto the two third grid plates 306, and then the carbon particles will flow along the inclined surfaces of the two third grid plates 306 to the four first guide plates 3011 and the two second guide plates 3012, and then control the six The electric slider 309 moves upward on the six electric slide rails 308, and then the four electric sliders 309 on the left and right drive the four second connecting plates 3010 to move upward, and the four second connecting plates 3010 drive the four first guide plates 3011 connected thereto to move upward, so that the four first guide plates 3011 move upward to contact the four limit blocks 3016 on the left and right, and then while moving further upward, the four first guide plates 3011 are limited by the four limit blocks 3016, and the four second connecting plates 3010 respectively rotate with the rotating shaft on the electric slider 309 as the rotation center, so that the four second connecting plates 3010 connected to the upper part of the four first guide plates 3011 deflect clockwise when viewed from the front to the back.Then, the carbon particles in the first guide plate 3011 flow into the four discharge pipes 3013 along the inclined first guide plate 3011, and flow into the adsorption space formed by the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307 through the four discharge pipes 3013. At the same time, the two electric sliders 309 located in the middle are controlled to move upward on the two electric slide rails 308. The two electric sliders 309 drive the two second connecting plates 3010 connected thereto to move upward. The two second connecting plates 3010 drive the two second guide plates 3012 to move upward and approach the two limit blocks 3016. Then, in the further moving process, the two second guide plates 3012 move upward and approach the two limit blocks 3016. Under the limiting effect of the two second connecting plates 3010 in the middle, the two second connecting plates 3010 are rotated with the rotating shafts on the two electric sliders 309 as the rotation center, and the carbon particles on the two first guide plates 3011 are poured into the two discharge pipes 3013 located on the left, and the poured carbon particles enter the adsorption space formed by the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307. After such transfer, the carbon particles in the adsorption space formed by the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307 at the bottom layer flow into the second grid plate 204, and the carbon particles in the adsorption space formed by the third connecting ring 301, the third grid plate 306 and the fourth grid plate 307 in the middle enter the adsorption space at the bottom layer. In the attached space, the carbon particles in the uppermost adsorption space enter the middle adsorption space. When the transfer is completed, the control motor 201 drives the rotating rod 202 to rotate. Looking from above to below is used as a reference. The rotating rod 202 rotates counterclockwise, and the rotating rod 202 drives the second connecting ring 208 to rotate counterclockwise; the second connecting ring 208 drives the brush plate 209 to rotate counterclockwise, so that the rotating shaft on the right side of the brush plate 209 slides in the groove opened in the material tank 102, and then the brush plate 209 moves the carbon particles on the surface of the second grid plate 204, and drives the carbon particles to move along the arc grid plate 205 to the second discharging track 207, and flow along the track of the second discharging track 207 to the first discharging track 105, and then the auger is controlled The conveyor 106 drives the carbon particles to move upward and flow into the fourth discharge track 304 located above, and then the uppermost component of the transfer system 3 works to rotate the carbon particles to the uppermost adsorption space, and then the brush plate 209 brushes multiple times to transfer the carbon particles on the second grid plate 204 to the uppermost adsorption space of the transfer system 3. While the brush plate 209 is working, the carbon particles are worn out and fall into the first grid plate 203. Since the grid density on the first grid plate 203 is less than that on the second grid plate 204, the carbon particles stay on the first grid plate 203. When all the carbon particles on the second grid plate 204 are transferred to the uppermost adsorption space, the air is then introduced to continue working.

[0050] When the carbon particles in the three-layer adsorption space are completely saturated after a long period of work, the transfer system 3 is controlled to transfer the carbon particles in the bottom layer to the second grid plate 204, and then the motor 201 is controlled to drive the rotating rod 202 to rotate clockwise, and the rotating rod 202 drives the second connecting ring 208 to rotate clockwise, and the second connecting ring 208 drives the brush plate 209 to rotate clockwise, so that the brush plate 209 slides away from one end of the second connecting ring 208 in the groove opened on the material tank 102, and when the right rotating shaft of the brush plate 209 moves close to the dial plate 109, in the further movement process, due to the wedge shape formed between the dial plate 109 and the groove, the brush plate 209 moves upward into the upper groove, and at the same time, the brush plate 209 drives the second connecting ring 208 to slide upward on the rotating rod 202, and then the brush plate 209 continues to rotate to evenly pave the carbon particles on the second grid plate 204 , and then use an external vacuum pump to extract the gas inside the material through the two air inlet pipes 103, so that the material tank 102 reaches a vacuum state, forcing the oxygen adsorbed in the carbon particles on the second grid plate 204 to be extracted, so that the carbon particles can continue to adsorb oxygen, and then continue to control the feeding system 1 and the paving system 2 to cooperate to transfer the carbon particles on the second grid plate 204 to the top adsorption space of the transfer system 3. In this process, the transfer system 3 is simultaneously controlled to transfer the carbon particles in the middle adsorption space to the bottom layer, and the carbon particles in the top adsorption space are transferred to the middle adsorption space, so that the carbon particles that have completed the extraction of oxygen enter the top adsorption space, and then operate in the same working mode to completely extract the oxygen in the carbon particles in the three-layer adsorption space, and collect it, and then continue to pass it into the space to work.
