Description

Technical Field

[0001] The present invention relates to the technical field of nitrogen production, and specifically to a rapid purification device for high-purity gas production. Background Technique

[0002] Nitrogen is a simple substance formed by nitrogen element, with the chemical formula N2. It is a colorless and odorless gas under normal temperature and pressure. It can only react with hydrogen to form ammonia under high temperature, high pressure and catalyst conditions, and can combine with oxygen to form nitric oxide under the condition of discharge. Nitrogen is the 30th most abundant element on the earth. Considering that nitrogen accounts for 4 / 5 of the atmosphere, that is, more than 78% of the atmosphere, almost an unlimited amount of nitrogen can be used. Nitrogen production machines will be used in the production process.

[0003] At the inlet of the existing nitrogen production machine, a filter screen is provided to filter dust in the air to avoid the influence of dust impurities on subsequent nitrogen purification operations. During the process of blocking dust impurities, some dust impurities with certain viscosity will be adsorbed on the surface of the filter screen. The long-term accumulation of dust impurities will cause the filter screen to become blocked, reducing the overall gas flow efficiency. Summary of the Invention

[0026] (3) The movement of the vibration frame will drive the transmission frame to perform vertical movement. The movement of the transmission frame will drive the internal fan blades to rotate and generate a short-distance air flow. The short-distance air flow can push the dust separated from the filter screen during the cleaning process downward, reducing the situation where the dust falls inside the main body of the nitrogen generator after cleaning;

[0027] (4) During the movement of the transmission frame, the sliding block will be driven to move. The cooperation between the sliding block and the sliding rod can limit the transmission frame to a certain extent, ensuring the stability of the transmission frame during vertical movement.

[0044] Embodiment 2

[0045] Please refer to Figure 1-11, the transmission part 6 is arranged inside the nitrogen generator main body 1. The transmission part 6 has a transmission frame 601 fixed above the cleaning frame 502. The transmission frame 601 is installed above the cleaning frame 502 through multiple groups of bolts, which is convenient for the staff to install and disassemble the transmission frame 601. A transmission rod 602 is rotatably connected inside the transmission frame 601. The transmission rod 602 is made of stainless steel to prevent the transmission rod 602 from rusting during long-term use. Both ends of the transmission rod 602 penetrate through the transmission frame 601, and a transmission gear 603 is fixedly sleeved on the transmission rod 602. The rotation of the transmission gear 603 can drive the transmission rod 602 to rotate. A gear rod 604 is fixedly installed inside the nitrogen generator main body 1. The gear rod 604 is installed inside the nitrogen generator main body 1 through bolts. A first bevel gear 605 is fixedly sleeved at the middle position of the transmission rod 602. The rotation of the transmission rod 602 can drive the first bevel gear 605 to rotate in the same way. A second bevel gear 606 is meshed and connected above the first bevel gear 605. The rotation of the first bevel gear 605 can drive the second bevel gear 606 to rotate. A large gear 607 is welded above the second bevel gear 606. The rotation of the second bevel gear 606 can drive the large gear 607 to rotate. A first rotating rod 608 is fixedly installed above the large gear 607. The bottom end of the first rotating rod 608 penetrates through the large gear 607, and the first rotating rod 608 is connected to the large gear 607 by welding, and the first rotating rod 608 is rotatably connected to the transmission frame 601. The top end of the first rotating rod 608 is rotatably connected to the transmission frame 601. A second rotating rod 610 is rotatably connected inside the transmission frame 601. Both ends of the second rotating rod 610 are rotatably connected to the transmission frame 601 to ensure the stability of the second rotating rod 610 during rotation. A small gear 609 is fixedly sleeved at the top end of the second rotating rod 610. The rotation of the small gear 609 can drive the second rotating rod 610 to rotate, and the small gear 609 is meshed and connected with the large gear 607. The rotation of the large gear 607 can drive the small gear 609 to rotate. A fan blade 611 is fixedly installed at the bottom end of the second rotating rod 610. The rotation of the second rotating rod 610 can drive the fan blade 611 to rotate. The rotation of the fan blade 611 can generate a downward output airflow, and the airflow can push the dust generated during the cleaning process downward. A sliding block 612 is fixedly installed on one side of the transmission frame 601 where the air inlet pipe 3 is located, and a sliding rod 613 is fixedly installed inside the nitrogen generator main body 1, and the sliding rod 613 is slidably connected with the sliding block 612. The transmission frame 601 is limited by the cooperation of the sliding block 612 and the sliding rod 613 to ensure the stability of the transmission frame 601 during movement. A total of five groups of fan blades 611 are arranged inside the transmission frame 601, and the five groups of fan blades 611 have the same shape and size. By arranging five groups of fan blades 611, a larger airflow can be generated, and the airflow can better push the dust inside the nitrogen generator main body 1 downward to the collection box 4. An air outlet is opened at the bottom of the transmission frame 601, and the air outlet is arranged above the cleaning plate 504.The airflow generated through the air outlet can clean the dust and impurities on the bristles of the cleaning plate 504 to a certain extent. The transmission frame 601 is provided with an air inlet on one side of the intake pipe 3, and a dust-proof net is provided at the air inlet to prevent dust and impurities from entering the interior of the transmission frame 601.,

[0046] Working principle: First, when it is necessary to clean the filter screen 2 inside the nitrogen generator main body 1, the control panel of the nitrogen generator main body 1 is controlled to start the lead screw slide 501. When the lead screw slide 501 works, it will drive the cleaning frame 502 to move up and down reciprocally. The vertical movement of the cleaning frame 502 can drive the vibration frame 503 to move up and down reciprocally. The up and down reciprocating movement of the vibration frame 503 will drive the cleaning plate 504 to perform the same movement. During the vertical movement of the vibration frame 503, it will also drive the roller 506 to move vertically. Since the roller 506 fits into the corrugated groove of the corrugated rod 507, during the vertical movement of the vibration frame 503, it will be affected by the roller 506 and perform a horizontal reciprocating movement. The horizontal movement of the vibration frame 503 will drive the cleaning plate 504 to perform a horizontal movement under the action of inertia. Since the cleaning plate 504 is in contact with the spring 505, and the other end of the spring 505 is in contact with the inner wall of the vibration frame 503, the movement of the cleaning plate 504 will cause the spring 505 to deform. When the spring 505 is compressed, it will restore its deformation and push the cleaning plate 504 to move, causing the cleaning plate 504 to vibrate at a high frequency with a small amplitude. The dust on the surface of the filter screen 2 is cleaned by the cleaning plate 504 vibrating at a high frequency during vertical movement, thereby reducing the occurrence of blockage of the filter screen 2 due to dust and impurities;

[0047] Secondly, during the vertical movement of the cleaning frame 502, it will also drive the transmission frame 601 to move. The vertical movement of the transmission frame 601 drives the transmission rod 602 to move. The vertical movement of the transmission rod 602 drives the transmission gear 603 to move. Since the transmission gear 603 is meshed with the gear rod 604, during the vertical movement of the transmission gear 603, it will be affected by the gear rod 604 and rotate. The rotation of the transmission gear 603 drives the transmission rod 602 to rotate. The rotation of the transmission rod 602 drives the first bevel gear 605 to rotate. The rotation of the first bevel gear 605 drives the second bevel gear 606 to rotate. The rotation of the second bevel gear 606 drives the large gear 607 to rotate. The rotation of the large gear 607 drives the small gear 609 to rotate. The rotation of the small gear 609 drives the second rotating rod 610 to rotate. The second rotating rod 610 drives the fan blade 611 to rotate. The rotation of the fan blade 611 generates an airflow, and the airflow is discharged through the air outlet at the bottom of the transmission frame 601. Through the airflow, the dust generated during the cleaning process can be pushed to move downward, and the downward movement of the dust will enter the collection box 4, which is convenient for subsequent unified treatment by the staff.
