Medical oxygen production equipment adopts the world's advanced PSA pressure swing adsorption air separation oxygen production technology, which is based on the difference in the adsorption capacity of zeolite molecular sieve attractants for oxygen and nitrogen in the air to achieve the separation of oxygen and nitrogen. The PSA oxygen production system is mainly composed of an air compressor, an air cooler, an air buffer tank, a switching valve, an adsorber and an oxygen balance tank.

[0003] After searching, the Chinese patent application number CN202011602671.7 discloses an oxygen purification device and a process thereof, which specifically relates to the field of oxygen purification technology, including a base frame, a gas storage tank is placed on one side of the top of the base frame, and a dewatering tank is fixedly installed on the other side of the top of the base frame. The present invention provides an inner frame, a sleeve, an inner tube and a first spring, and when the gas storage tank is full and needs to be replaced, the connecting pipe is pulled upward. An oxygen purification device and a process thereof in the above patent have the following deficiencies:

[0004] Although the overall device achieves the task of oxygen purification, the air conduction efficiency is relatively low during air purification, resulting in a small amount of high-oxygen purification per unit time. Therefore, a high-purity oxygen purification process and equipment are urgently needed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a high-purity oxygen purification process and equipment.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A high-purity oxygen purification device comprises a purification box, wherein the outer walls at the four corners of the bottom of the purification box are respectively provided with supporting feet, the outer wall at the bottom center of the purification box is provided with an air guide hopper, the outer wall at the bottom of the air guide hopper is provided with a collecting pipe, the outer wall on the front side of the purification box is hinged with a box door through a hinge, and the front side of the box door is provided with a handle, the top outer wall of the purification box is provided with an air inlet pipe, the bottom end of the air inlet pipe is provided with an air guide cylinder, a motor is fixed to one side of the top of the purification box through a mounting block, a rotating drum is welded to the circumferential outer wall of the air guide cylinder, a rotating air guide mechanism is provided at the output end of the motor, and a mixing box is provided at the rotating end of the rotating air guide mechanism, support plates are respectively provided on the inner walls on both sides of the purification box, and carbon dioxide adsorption nets distributed equidistantly are provided on the opposite sides of the two support plates, and guide holes are opened on the bottom inner wall of the purification box.

[0008] Preferably: the rotating air guide mechanism includes three guide rods, a transmission belt, a triangular bracket, an air push cylinder and a guide plate, and the three guide rods are respectively rotated in three rotating drums through rotating shafts, and a guide shaft is rotatably connected to the inside of one of the rotating drums through a bearing.

[0009] Furthermore: the guide shaft is connected to one of the rotating shafts via a thread, the output end of the motor is connected to a fixed shaft via a coupling, the circumferential outer walls of the fixed shaft and the guide shaft are respectively sleeved with transmission wheels, and the transmission belts are respectively sleeved on the circumferences of the two transmission wheels.

[0010] On the basis of the above-mentioned solution: the three ports of the triangular bracket are respectively connected to one end of three guide rods through a rotating shaft, and a mounting hole is opened on the top outer wall of the triangular bracket.

[0011] A better solution in the above solution is: the air push cylinder is arranged in the mounting hole, and the air mixing box is connected to the air push cylinder through threads.

[0012] At the same time, the guide plate is welded to the top of the air thrust cylinder, and the structure of the guide plate is stepped, and a molecular sieve is arranged on the circumferential inner wall of the air thrust cylinder.

The three guide rods drive the push cylinder inside the triangular bracket to make a circular motion, and also drive the mixing box to make a circular motion;

[0017] S2: During the process of the air cylinder rotating and pushing, the stepped guide plate promotes the rotation speed of the air and makes the air fall into the molecular sieve to eliminate the nitrogen in the air;

[0018] S3: When the air sieved by the molecular sieve enters the support tube through the air pusher, the gathering holes in the support tube are compressed by the caliber, which promotes the flow rate of the air;

At this time, the mixing box at the rotating end of the rotating air guide mechanism rotates and guides the air, which improves the efficiency of air conduction, ensures the amount of air passing through per unit time, and improves the efficiency of subsequent air purification. At the same time, the air in the mixing box continues to be guided, and the air is spread on the multi-layer carbon dioxide adsorption network, which effectively removes the carbon dioxide in the air, and the air after the carbon dioxide is removed is introduced into the air guide bucket through the guide hole, and the high-purity oxygen is conducted and collected by the collection pipe at the bottom of the air guide bucket.

[0023] 2. This high-purity oxygen purification process and equipment, drives the fixed shaft to rotate through the motor, and drives the guide shaft to rotate through the transmission belt, the rotating guide shaft drives one of the rotating shafts to rotate, and its rotation causes the three guide rods to rotate simultaneously, and the three guide rods drive the air push cylinder inside the triangular bracket to make circular motion, and also drive the mixing box to make circular motion. At this time, during the rotation and deduction of the air push cylinder, the stepped guide plate promotes the rotation speed of the air, and makes the air fall into the molecular sieve to eliminate the nitrogen in the air. Therefore, the air in the air guide cylinder can be rotated and guided, which effectively promotes the air flow rate, expands the flow rate of air purification, and ensures the efficiency and quality of air purification.
