Description

Technical Field

[0001] The invention relates to the technical field of oxygen production, in particular to a medical molecular sieve central oxygen production system. Background Art

[0002] The molecular sieve oxygen production system is a device used to prepare oxygen, including air compressors, dryers, molecular sieve oxygen generators, oxygen concentration detectors, oxygen storage tanks, busbars and other equipment. The principle of the molecular sieve oxygen generator is to adsorb nitrogen, carbon dioxide and other gases in the air by molecular sieves, and the outflowing gas is high-purity oxygen. The existing molecular sieve oxygen generator has certain defects: because the direction of the internal airflow changes during adsorption and regeneration of the adsorption cylinder, the molecular sieve in the adsorption cylinder is in a boiling state for a long time. In this state, the friction between the molecular sieves increases, which can easily cause the molecular sieve to pulverize. When the molecular sieve is pulverized, the molecular sieve will be found to be seriously settled when the adsorption cylinder cover is removed. If the pressure net and pressure plate of the molecular sieve designed to prevent the molecular sieve from being carried away by the airflow are installed and laid out unreasonably, the pressure net and pressure plate are easily deformed and damaged, resulting in the molecular sieve being carried out, causing the molecular sieve to pulverize and the adsorption performance to decrease, which not only reduces the adsorption efficiency of the molecular sieve and affects the air quality, but also affects the normal operation of downstream instruments and equipment, and even causes pipeline blockage.

[0003] Based on the above defects, a medical molecular sieve central oxygen production system disclosed in this device can solve the above problems. Summary of the invention

The air compressor 1 is used to compress the air, the main filter 2 is used to filter larger particulate impurities such as dust in the compressed air, the dryer 3 is used to heat the air to vaporize and discharge the moisture and volatile liquid in the air, the No. 1 precision filter 4 is used to remove suspended particles, colloids, microorganisms, etc. in the air, the air storage tank 5 is used to temporarily store the air that has been preliminarily treated, the molecular sieve oxygen generator 6 is used to sieve out other molecules in the air to produce high-concentration oxygen, and the oxygen concentration detector 7 is used to detect the concentration of oxygen prepared by the molecular sieve oxygen generator 6. If the concentration meets the standard, the oxygen is stored in the oxygen storage tank 8. If the oxygen does not meet the standard, , oxygen is trapped in the molecular sieve oxygen generator 6 to further increase the oxygen concentration. The bus 9 is used to store oxygen. The molecular sieve oxygen generator 6 includes an oxygen generator cylinder 10, an anti-powdering mechanism 11, and a power mechanism 12. The oxygen generator cylinder 10 is provided with an anti-powdering mechanism 11. The anti-powdering mechanism 11 is used to prevent the molecular sieve from being pulverized, extend the service life of the molecular sieve, and enhance the oxygen production efficiency of the system. The middle part of the oxygen generator cylinder 10 is provided with a power mechanism 12. The anti-powdering mechanism 11 is driven to rotate by the power mechanism 12. The anti-powdering mechanism 11 rotates at a high speed under the drive of the power mechanism 12, so that the molecular sieve in the anti-powdering mechanism 11 performs a high-speed circular motion. The molecular sieve is almost always attached to the inner wall under the action of centrifugal force, so that the collision of the airflow inside the molecular sieve is greatly weakened, and the molecular sieves are prevented from rubbing and colliding with each other due to being in a boiling state, thereby greatly avoiding the pulverization of the molecular sieve.

[0030] like Figures 2 to 5 The anti-powdering mechanism 11 includes a rotating column 13, a through slot 14, a mesh 15, a slow-motion spring structure 16, and a molecular sieve 17.

A plurality of through slots 14 are provided inside the rotating column 13, and the through slots 14 are open at both ends. The mesh 15 is provided at both upper and lower ends of the through slots 14. The mesh 15 is non-fixedly connected to the upper and lower ends of the through slots 14.

The through slot 14 is provided with a slow-motion spring structure 16, and the molecular sieve 17 is provided inside the slow-motion spring structure 16. The molecular sieve 17 is placed in the slow-motion spring structure 16, and the molecular sieve 17 can be isolated from the inner wall of the through slot 14. When the molecular sieve 17 generates internal airflow, the elastic action of the slow-motion spring structure 16 weakens the collision between the molecular sieve 17 and the inner wall of the through slot 14, thereby further avoiding the pulverization of the molecular sieve 17.

[0031] like Figure 4The slow-motion spring structure 16 includes a slow-motion section 18 and a dividing section 19. The cross-sectional diameter of the dividing section 19 is smaller than that of the slow-motion section 18. The slow-motion section 18 is used to place the molecular sieves 17, and the dividing section 19 is used to isolate the molecular sieves 17 from each other, further avoiding collision and friction between the molecular sieves. At the same time, the slow-motion effect of the slow-motion section 18 further offsets the airflow effect inside the molecular sieve 17, that is, the airflow effect drives the molecular sieve 17 to shake along with the slow-motion section 18, avoiding collision between the molecular sieve 17 and the inner wall of the through groove 14. When the molecular sieve needs to be replaced in the slow-motion spring structure 16, the slow-motion spring structure 16 is lengthened to enlarge the gap of the slow-motion section 18, and the entire slow-motion spring structure 16 is placed in the molecular sieve 17, which can be replaced and is easy to use.

The third gear 23 is meshed with the outer wall of the second gear 22. A motor 24 is arranged outside the annular chamber 21. The motor 24 is used to drive the third gear 23 to rotate. The output end of the motor 24 is connected to the third gear 23 through a connecting rod. The connecting rod and the annular chamber 21 are sealed by an oil seal. The setting of the annular chamber 21 prevents the second gear 22, the third gear 23, etc. from interfering with the anti-powdering mechanism 11, so that the anti-powdering mechanism 11 can be removed and replaced with a new molecular sieve 17 conveniently.

[0034] like Figures 2-3A cylinder cover 25 is provided at the upper end of the oxygen concentrator cylinder 10, and the cylinder cover 25 is sealed and connected to the oxygen concentrator cylinder 10.

The ball valve 48 is used to control the flow of the branch 47. When the equipment needs maintenance, the branch 47 is opened to release the gas for maintenance of the equipment to prevent the gas in the bus 9 from being contaminated.

[0039] The working principle of the present invention is as follows: the air compressor 1 first compresses the air, and the dust and other larger particulate impurities in the compressed air are filtered through the main filter 2, and then the dryer 3 heats the air to vaporize and discharge the moisture and volatile liquid in the air, and then the No. 1 precision filter 4 is used to remove the amount of suspended particles, colloids, microorganisms, etc. in the air, and the treated air is placed in the air storage tank 5 for temporary storage, and then the molecular sieve oxygen generator 6 is used to sieve out other molecules in the air to produce high-concentration oxygen, and the oxygen concentration detector 7 detects the oxygen concentration prepared by the molecular sieve oxygen generator 6. If the concentration meets the standard, the oxygen is stored in the oxygen storage tank 8. If the oxygen does not meet the standard, the oxygen is trapped in the molecular sieve oxygen generator 6 to further increase the oxygen concentration, and the prepared oxygen is collected in the bus 9 for storage;

[0040] Before the oxygen enters the bus 9 from the oxygen concentration detector 7, the second precision filter 42 further removes impurities in the oxygen, the oxygen concentration display 43 displays the concentration of the oxygen discharged from the oxygen storage tank 8, the flow meter 44 detects the flow of the oxygen discharged from the oxygen storage tank 8, the pressure regulating valve 45 controls the flow of oxygen, and the check valve 46 prevents the oxygen in the pipeline from flowing back;

[0041] The principle of the molecular sieve oxygen generator 6 is as follows: the power mechanism 12 drives the anti-powdering mechanism 11 to rotate, the air is input through the air inlet 27, the molecular sieve 17 in the anti-powdering mechanism 11 extracts oxygen, and the oxygen is output through the air outlet 26;

[0042] The principle of the power mechanism 12 is: the motor 24 drives the third gear 23 to rotate, the third gear 23 drives the second gear 22 to rotate, the second gear 22 drives the first gear 20 to rotate, and then drives the anti-powdering mechanism 11 to rotate;

[0043] The principle of the anti-powdering mechanism 11 is as follows: the rotating column 13 rotates, so that the slow-motion spring structure 16 and the molecular sieve 17 in the through groove 14 are subjected to centrifugal force, and the molecular sieve 17 rotates against the inner wall of the through groove 14 through the slow-motion spring structure 16, and no relative movement occurs between the molecular sieve 17 and the through groove 14. When the rotating speed of the rotating column 13 is relatively high, the collision of the airflow inside the molecular sieve 17 will be greatly weakened, and the mutual friction and collision of the molecular sieve 17 due to being in a boiling state will be avoided, and the pulverization of the molecular sieve 17 will be avoided to a great extent. At the same time, the slow-motion spring structure 16 isolates the molecular sieve 17 from the inner wall of the through groove 14. When the molecular sieve 17 generates internal airflow, the collision between the molecular sieve 17 and the inner wall of the through groove 14 is weakened under the elastic action of the slow-motion spring structure 16, and the pulverization of the molecular sieve 17 is further avoided.
