[0012] The technical effects and advantages of the present invention: 1. The present invention initially disperses and outputs air through an air jet disc. Subsequently, the air is ejected from the air disc, passes through the air diffusing holes opened on the surface of the air diffusing plate, and finally is discharged from the holes opened on the circumferential surface of the air diffusing shell, enabling the compressed air to diffuse in all directions and then be conveyed upward.

At the same time, after the molecular sieve has filtered and prepared oxygen for a long time, the exhaust port of the air jet disc is blocked, and the compressed air is directly conveyed into the shunt pipe through the connecting pipe. Subsequently, it is discharged downward through multiple exhaust pipes installed on the shunt pipe. When discharging the compressed air, a negative pressure can be generated in the inclined pipe, and then nitrogen and pulverized molecular sieve filtered by the molecular sieve can be absorbed from the inside of the molecular sieve through the adsorption shell, enabling the nitrogen and dust to be discharged from the tower body together through the exhaust pipe, achieving the effect of cleaning the molecular sieve and improving the efficiency and quality of oxygen preparation.

[0013] 2. The present invention raises the position of the upper plug plate so that the position of the upper plug plate is higher than the feed port. Subsequently, molecular sieve particles can be supplemented into the tower body through the feed port. At the same time, the second cam is controlled to rotate, and with the cooperation of the tension spring, the lower plug plate can be controlled to vibrate. When the molecular sieve particles are supplemented into the tower body, the lower plug plate vibrates to compact them. After the supplementation is completed, the upper plug plate is pressed down, thereby increasing the overall density of the molecular sieve, making it not easily loosened by the action of the air flow during operation, slowing down the pulverization speed of the molecular sieve, and increasing its service life.

Detailed implementation manners

[0016] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples. An oxygen-making main engine adsorption tower capable of preventing molecular sieve pulverization involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0017] As Figure 1-7As shown, in one embodiment, an adsorption tower of an oxygen generation main unit capable of preventing molecular sieve pulverization is proposed, which includes a tower body 1. A tower cover 101 is installed at the upper end of the tower body 1, and an output pipe 102 is installed at the upper end of the tower cover 101. An adsorption assembly 2 is arranged inside the tower body 1, and an air inlet pipe 103 is installed at the lower end of the tower body 1. A flow splitting assembly 3 and a dredging assembly 4 are installed inside the tower body 1. The flow splitting assembly 3 includes a connecting pipe 301, communication holes 302, a jet disk 304, and a diffuser plate 305. The connecting pipe 301 is installed inside the upper end of the air inlet pipe 103, and a plurality of communication holes 302 are opened on the circumferential surface of the connecting pipe 301. A sliding cylinder 303 is slidably connected to the circumferential surface of the connecting pipe 301. The jet disk 304 is installed on the circumferential surface of the sliding cylinder 303 and is slidably connected to the connecting pipe 301. The diffuser plate 305 is installed inside the tower body 1, and a plurality of diffuser holes 306 are opened on the surface of the diffuser plate 305. A plurality of diffuser shells 307 are installed at the upper end of the diffuser plate 305, and a plurality of exhaust holes 308 are opened on the circumferential surface of the diffuser shell 307; The dredging assembly 4 includes a flow splitting pipe 401, an exhaust pipe 402, and a communication pipe 403. The flow splitting pipe 401 is installed at the upper end of the air inlet pipe 103, and a plurality of exhaust pipes 402 are all installed on the flow splitting pipe 401. The communication pipe 403 is installed at the lower ends of the plurality of exhaust pipes 402. A plurality of inclined pipes 404 are installed on the circumferential surface of the exhaust pipe 402, and an adsorption shell 405 is installed at the end of the inclined pipe 404 away from the exhaust pipe 402.

[0018] In the actual application of the embodiment of the present invention, the compressed air is input into the connecting pipe 301 through the air inlet pipe 103. Subsequently, the compressed air enters the jet disk 304 through the communication holes 302, and the air is preliminarily dispersed and output. Then the compressed air is ejected from the jet disk 304, and then passes through the diffuser holes 306 opened on the surface of the diffuser plate 305, and finally is discharged from the holes opened on the circumferential surface of the diffuser shell 307, so that the compressed air diffuses around. When the compressed air is conveyed upward, it effectively achieves the effect of diffusing the air, reduces the impact on the molecular sieve 205 in the upper adsorption assembly 2, reduces the pulverization speed of the molecular sieve 205, and improves the service life. At the same time, after the molecular sieve 205 filters and prepares oxygen for a long time, the exhaust port of the jet disk 304 is blocked, so that the compressed air is directly conveyed into the flow splitting pipe 401 through the connecting pipe 301, and then is discharged downward through the plurality of exhaust pipes 402 installed on the flow splitting pipe 401. When the compressed air is discharged through the exhaust pipe 402, since a plurality of inclined pipes 404 are installed on the circumferential surface of the exhaust pipe 402, a negative pressure can be generated in the inclined pipes 404 when the compressed air is discharged, and then the nitrogen and pulverized molecular sieve 205 filtered by the molecular sieve 205 can be absorbed from the inside of the molecular sieve 205 through the adsorption shell 405, so that the nitrogen and dust are discharged from the tower body 1 together through the exhaust pipe 402, realizing the effect of cleaning the molecular sieve 205 and improving the efficiency and quality of oxygen preparation.

[0019] As Figure 2 、 6As shown in Figure 7, as a preferred embodiment of the present invention, the adsorption assembly 2 includes an upper baffle plate 204, a lower baffle plate 202 and a molecular sieve 205. A plurality of guide seats 201 are installed on the inner wall of the tower body 1. The lower baffle plate 202 is slidably connected in the guide seat 201 through a guide shaft 203. A plurality of guide rods 206 are installed at the lower end of the tower cover 101. The upper baffle plate 204 is slidably connected to the circumferential surface of the guide rod 206. A molecular sieve 205 is arranged between the upper baffle plate 204 and the lower baffle plate 202. The upper baffle plate 204 and the lower baffle plate 202 are both slidably connected to the connecting pipe 301 and the exhaust pipe 402.

[0020] In actual application of the embodiment of the present invention, the molecular sieve 205 is stored in the tower body 1, supported by the lower plugging plate 202 below, and then compacted by the upper plugging plate 204 above. When the compressed air passes through the molecular sieve 205, it can filter the nitrogen and allow the oxygen to be discharged and collected through the output pipe 102.

[0021] like Figure 2-5 As shown, as another preferred embodiment of the present invention, a rack 5 is installed on the upper end of the jet disc 304, the rack 5 is slidably connected to the diffuser plate 305, a rotating shaft 501 is rotatably connected in the connecting pipe 301, a valve plate 502 and a rotating gear 503 are installed on the circumferential surface of the rotating shaft 501, and the rack 5 is meshed with the rotating gear 503.

[0022] When the embodiment of the present invention is actually used, the slide 303 is controlled to move upward, so that the positions of the jet disc 304 and the rack 5 rise. When the rack 5 moves upward, it can drive the rotating gear 503 to rotate. The rotating gear 503 drives the valve plate 502 to rotate through the rotating shaft 501, thereby releasing the blockage above the connecting pipe 301, allowing the compressed air to be transported to the diversion pipe 401, and controlling the dredging component 4 to open, thereby achieving the effect of cleaning the molecular sieve 205.

[0023] like Figure 4 and 5 As shown in FIG. 1 , as another preferred embodiment of the present invention, a connecting frame 504 is installed in the diffuser hole 306 , a blocking block 505 is installed in the connecting frame 504 , and the blocking block 505 is slidably connected to the jet disc 304 .

[0024] In the actual application of the embodiment of the present invention, when the jet disk 304 moves upward, the exhaust port of the jet disk 304 will be blocked by the blocking block 505, so that the compressed air does not output from the jet disk 304. Instead, after the synchronous valve plate 502 is opened, all of it is transported to the shunt pipe 401 through the connecting pipe 301, and the compressed air is discharged from the multiple shunt pipes 401, generating a negative pressure in the inclined pipe 404, absorbing nitrogen and pulverized molecular sieve 205 from inside the molecular sieve 205, achieving the effect of cleaning the molecular sieve 205, improving the subsequent oxygen preparation efficiency and quality. At the same time, when the jet disk 304 descends and resets, the valve plate 502 rotates synchronously and closes. At this time, the exhaust disk is in an open state, and the valve plate 502 blocks the air transport path at the upper end of the jet disk 304, so that the compressed air is all output through the jet disk 304, and finally oxygen is prepared through the filtration of the molecular sieve 205.

[0025] As Figure 2-5 shown, as another preferred embodiment of the present invention, a servo motor 506 is installed inside the tower body 1, a drive shaft 507 is installed at the output end of the servo motor 506, a pair of connecting shafts 508 are rotatably connected inside the tower body 1, a first one-way gear 509 is installed on the circumferential surface of the drive shaft 507, and a first connecting gear 5010 installed on the circumferential surface of one of the connecting shafts 508 is connected to the first one-way gear 509 through a chain. The connecting shafts 508 are connected through a first sprocket set 5011. First cams 5012 are installed on the circumferential surfaces of the connecting shafts 508, a push plate 5013 is installed on the circumferential surface of the sliding cylinder 303, and a first spring 5014 is installed between the sliding cylinder 303 and the connecting pipe 301.

[0026] In the actual application of the embodiment of the present invention, the drive motor is controlled to operate, the drive motor drives the drive shaft 507 to rotate. Through the action of the first one-way gear 509, the first connecting gear 5010 and the chain, the drive shaft 507 drives the connecting shaft 508 to rotate. Then, through the action of the first sprocket set 5011, the two connecting shafts 508 rotate synchronously, thereby driving the multiple first cams 5012 to rotate. After controlling the first cam 5012 to rotate 180 degrees, the convex part of the first cam 5012 jacks up the push plate 5013, thereby driving the sliding cylinder 303 and the jet disk 304 to lift, achieving the effect of blocking the jet disk 304.

[0027] As Figure 1 and 2 shown, as another preferred embodiment of the present invention, a feed port 6 and a discharge port 601 are installed on the surface of the tower body 1, and sealing blocks 602 are installed inside the feed port 6 and the discharge port 601.

[0028] In practical application of the embodiment of the present invention, when the sealing block 602 in the discharge port 601 is opened, the molecular sieve 205 particles in the tower body 1 can be discharged, and then it is closed. Then, when the sealing block 602 in the feed port 6 is opened, the molecular sieve 205 can be replenished into the tower body 1, thereby achieving the effect of facilitating the discharge and replacement of the molecular sieve 205 in the tower body 1.

[0029] As Figure 6 and 7 shown, as another preferred embodiment of the present invention, a pair of threaded rods 603 are connected to the tower cover 101 by internal threads. A pair of lifting frames 605 are installed at the upper end of the upper plug plate 204. The threaded rods 603 are slidably connected to the lifting frames 605. A second spring 604 is installed between the tower cover 101 and the upper plug plate 204.

[0030] In practical application of the embodiment of the present invention, the threaded rods 603 are rotated simultaneously, so that the lower ends of the threaded rods 603 pull the lifting frames 605 to move upward, thereby driving the upper plug plate 204 to move upward, making the position of the upper plug plate 204 higher than the feed port 6. Then, the molecular sieve 205 particles can be replenished into the tower body 1 through the feed port 6. When the quantitative replenishment of the molecular sieve 205 particles is completed, the threaded rods 603 are controlled to rotate in the reverse direction to reset. After the threaded rods 603 are reset, enough space is left for the second spring 604 to press down the upper plug plate 204. At this time, under the action of the second spring 604, the upper plug plate 204 can be pushed to descend, so that the upper plug plate 204 presses down the molecular sieve 205 below, which can prevent the molecular sieve 205 particles from being pulverized by the airflow impact.

[0031] As Figure 9 and 10 shown, as another preferred embodiment of the present invention, a connecting rod 707 and a pair of driven shafts 7 are rotatably connected in the tower body 1. The connecting rod 707 is connected to the driving shaft 507 through a second sprocket set 701. A second one-way gear 702 is installed on the circumferential surface of the connecting rod 707. A second connecting gear 703 installed on the circumferential surface of one of the driven shafts 7 is connected to the second one-way gear 702 through a chain. The driven shafts 7 are connected through a third sprocket set 704. Second cams 705 are installed on the circumferential surfaces of the driven shafts 7. A tension spring 706 is installed between the guide seat 201 and the lower plug plate 202.

[0032] In the actual application of the embodiment of the present invention, when replenishing the molecular sieve 205 particles from the feed port 6, the servo motor 506 is controlled to reverse. The drive shaft 507 drives the connecting rod 707 to rotate through the second sprocket group 701. The connecting rod 707 drives the driven shaft 7 to rotate under the action of the second one-way gear 702, the second connecting gear 703 and the chain. Then, under the action of the third sprocket group 704, the two driven shafts 7 rotate synchronously, driving a plurality of second cams 705 to rotate. At the same time, with the cooperation of the tension spring 706, the lower plug plate 202 can be controlled to vibrate. When the molecular sieve 205 particles are replenished into the tower body 1, the lower plug plate 202 vibrates to compact them. After the replenishment is completed, the upper plug plate 204 is pressed down, thereby increasing the overall density of the molecular sieve 205, making it not easily loosened by the action of the air flow during operation, slowing down the pulverization speed of the molecular sieve 205, and increasing its service life.

[0033] In one case of the embodiment of the present invention, since the rotation directions of the first one-way gear 509 and the second one-way gear 702 are opposite, when the first one-way gear 509 rotates, the second one-way gear 702 idles, and when the second one-way gear 702 rotates, the first one-way gear 509 idles, thereby achieving the effect of independently controlling the rotation of the first cam 5012 or the second cam 705.

[0034] Finally, several points should be noted: First, in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, which can be mechanical connection or electrical connection, or the internal connection of two components, and can be directly connected.
