Description

Technical Field

[0001] The present invention relates to the technical field of oxygen-making air distribution systems, and particularly to a spiral air flow distribution oxygen-making system. Background Art

[0002] During the gas adsorption process, the uniformity of air flow distribution has a direct impact on the adsorption efficiency and product quality. Traditional air flow distribution methods often have problems such as uneven air flow distribution and local overload, which not only reduce the adsorption efficiency but may also cause excessive wear of the adsorption tower materials and shorten the service life of the equipment. Therefore, developing an air flow distribution technology in the adsorption tower that can achieve uniform air flow distribution is the key to improving the adsorption efficiency and product quality.

[0003] For example, a Chinese patent discloses "an efficient molecular sieve oxygen-making sound insulation structure" (Patent No.: CN201922410142.6). This patent includes a sound insulation outer tube, a first sound insulation unit, and a second sound insulation unit. The first sound insulation unit includes a sound insulation inner tube, sound insulation holes, and a petroleum fiber cotton layer. The sound insulation inner tube is nested inside the sound insulation outer tube. The part of the sound insulation inner tube nested inside the sound insulation outer tube is a spiral pipeline. The spiral pipeline is evenly provided with sound insulation holes, and a petroleum fiber cotton layer is bonded to the periphery of the spiral pipeline. The second sound insulation unit includes a rigid fiber cover and a full copper muffler. The rigid fiber cover is threadedly connected to the sound insulation inner tube, and full copper mufflers are symmetrically threadedly connected to the upper surface of the rigid fiber cover on the left and right. The spiral pipeline of the sound insulation inner tube can reduce the impact of air flow on the sound insulation inner tube, thereby achieving the effect of reducing noise. The rigid fiber cover absorbs the noise generated by the air flow passing through the sound insulation inner tube, and the full copper muffler reduces the noise of the air flow inside the rigid fiber cover and discharges it.

[0004] However, although the above-mentioned oxygen-making molecular sieve adopts the design of a spiral pipeline, its main purpose is to reduce the impact of air flow on the sound insulation inner tube through the spiral pipeline, thereby achieving the effect of reducing noise, and the air distribution method does not substantially help to improve the adsorption efficiency of the air flow.

Detailed implementation mode

[0032] An embodiment of the present invention provides a spiral air flow distribution oxygen generation system, as Figures 1-8 shown, including an adsorption tower 101. A detachable top 104 of the adsorption tower is installed at the top of the adsorption tower 101. A detachable bottom cover plate 106 of the tower is installed at the bottom of the adsorption tower 101. An adsorption cavity 110 with an opening running through and communicating is arranged inside the adsorption tower 101. A spiral air distribution guide plate 115 is fixedly arranged on the inner wall of the adsorption cavity 110. A spiral groove 113 in a spiral shape is arranged in the air distribution guide plate 115. An adjusting rotary plate 114 capable of moving up and down is arranged in the spiral groove 113. A vertical support column 111 is fixedly arranged at the center position of the lower end inside the top 104 of the adsorption tower. The support column 111 is cylindrical, and the support column 111 is inserted into the central groove position inside the air distribution guide plate 115.

[0033] As Figure 6 shown, two adjusting grooves 116 with openings facing outwards are arranged on both sides of the top of the adsorption tower 101. Lifting support rods 118 capable of moving up and down are arranged in the adjusting grooves 116.

[0034] Furthermore, a cross-frame support plate 117 is horizontally arranged at the top of the lifting support rod 118. Connecting rods 119 are fixedly arranged at the lower ends of the cross-frame support plates 117 on both sides. One of the connecting rods 119 on one side is longer than the connecting rod 119 on the other side. The upper end of the adjusting rotary plate 114 is installed and connected to the connecting rods 119 on both sides.

[0035] Furthermore, pneumatic lifters 109 are fixedly arranged on both sides of the outer end face of the adsorption tower 101. A propulsion cylinder is arranged inside the pneumatic lifter 109. The pneumatic lifter 109 can push and drive the lifting support rod 118 to move up and down.

[0036] When the lifting support rod 118 is activated, it can drive the lifting support rod 118 to move up and down through the internal propulsion cylinder. Furthermore, it can drive the connecting rod 119 to move up and down through the transmission of the cross-frame support plate 117. The connecting rod 119 can drive the entire regulating rotary plate 114 to move up and down. At this time, when the regulating rotary plate 114 moves to the upper limit position, the regulating rotary plate 114 moves to close the spiral groove 113 and forms a single-connected spiral pipeline in combination with the air distribution guide plate 115. At this time, the air flow flows internally. When the regulating rotary plate 114 is driven to move to the lower limit position, the regulating rotary plate 114 is located between the upper and lower layers of threads of the air distribution guide plate 115. At this time, through the cooperation between the regulating rotary plate 114 and the air distribution guide plate 115, an air flow guiding channel with a denser spiral can be formed, and the air flow and nitrogen adsorption efficiency can be further improved.

[0037] Furthermore, an installation connection slot 112 with an opening facing outward is provided at the bottom of the support column 111.

[0038] Furthermore, a guiding input cavity 124 with an opening facing upward is provided inside the tower bottom cover plate 106. A power shaft 125 is rotatably provided at the bottom inside the guiding input cavity 124. A rotating column 122 is fixedly connected to the top end of the power shaft 125. The top end of the rotating column 122 is rotatably connected to an installation connection plate 121, and the installation connection plate 121 can be installed and connected to the installation connection slot 112.

[0039] Furthermore, a plurality of guiding plates 123 are installed on the outer surface of the installation connection slot 112 from top to bottom, and the guiding plates 123 are in a circular ring shape.

[0040] It is worth further noting that the diameter of the guiding plate 123 gradually decreases from top to bottom.

[0041] Furthermore, a power motor 107 is fixedly provided at the lower end of the tower bottom cover plate 106, and one end of the power shaft 125 is power-connected to the power motor 107.

[0042] Furthermore, an input pipeline 105 is communicatively provided on the side of the tower bottom cover plate 106 and extends to the lower part inside the guiding input cavity 124. A flow detector 108 is installed and connected to the outer end surface of the input pipeline 105.

[0043] It is worth noting that the flow detector 108 can detect the air flow velocity flowing through the input pipeline 105.

[0044] Furthermore, an output air pipe 103 is communicatively provided on one side of the top end of the adsorption tower top 104 and extends above the adsorption cavity 110. A detector 102 is installed on one side of the output air pipe 103.

[0045] It needs to be further explained that the detector 102 is used to detect the temperature and oxygen content of the air flow output to the output air pipe 103.

[0046] When working, first install the top 104 of the adsorption tower on the top of the adsorption tower 101, and install and insert the support column 111 into the central groove position of the air distribution guide plate 115. Then insert the installation connecting plate 121 into the installation connection slot 112, and install the bottom cover plate 106 under the adsorption tower 101. At this time, connect the input pipeline 105 with the oxygen input pipeline. At this time, start the power motor 107 to drive the power shaft 125 to rotate, then drive the rotating column 122 to rotate, and then drive the guide plates 123 on each side to rotate. At this time, as the guide plates 123 arranged in a gradient size distribution from bottom to top rotate, the air flow is promoted to be guided through the guide plates 123. First, the oxygen input to the bottom of the guide input cavity 124 is diffused around and output upward in this way, and at the same time, the oxygen content of the input is detected by the flow detector 108.

[0047] At this time, first adjust the rotary plate 114 to the upper limit position. At this time, the lifting support rod 118 is started, and the lifting support rod 118 is driven to move up and down by the internal propulsion cylinder. Then, through the transmission of the cross frame support plate 117, the connecting rod 119 is driven to move up and down. The connecting rod 119 can drive the entire rotary plate 114 to move up and down. At this time, when the rotary plate 114 moves to the upper limit position, the rotary plate 114 moves to close the spiral groove 113, and a single connected spiral pipeline is formed by the combination of the rotary plate 114 and the air distribution guide plate 115. At this time, the input oxygen is output upward through the formed spiral pipeline. When the oxygen is output upward along the spiral pipeline, a spiral air flow is formed, and through the spiral air distribution method, a spiral flow path is generated. This flow method helps to improve the contact efficiency between the air flow and the inner wall of the adsorption tower, reduce the dead zone of the air flow in the adsorption tower, and thus improve the adsorption efficiency.

[0048] When the oxygen is input upward to the uppermost side and output outward through the output air pipe 103, at this time, the detector 102 monitors the temperature of the output air flow and detects the oxygen concentration. When the oxygen concentration does not meet the standard, at this time, the rotary plate 114 is driven by the push cylinder to move to the lower limit position. At this time, the rotary plate 114 is located between the threads of the upper and lower layers of the air distribution guide plate 115. At this time, through the cooperation between the rotary plate 114 and the air distribution guide plate 115, a spiral air flow guiding channel with a denser spiral can be formed, thereby improving the contact efficiency between the air flow and the inner wall of the adsorption tower. Through this transformation, a more uniform air flow can be obtained, which helps to improve the service life of the molecular sieve and reduce the maintenance cost.

[0049] Moreover, by changing the internal spiral air flow direction and its contact area, the rotary air flow distribution technology can adjust and optimize the distance between the rotary plate 114 and the air distribution guide plate 115 according to adsorption towers of different scales and types, with good adaptability. By optimizing the air flow distribution, energy consumption is reduced. After improving the nitrogen adsorption efficiency of the air flow, the wear of the adsorption tower materials is reduced at the same time, and the service life of the equipment is extended.
