Description
Technical Field
[0001] This invention relates to the technical field of oxygen generators, and in particular to an industrial oxygen generator. Background Technology
[0002] Industrial oxygen generators are industrial devices that extract oxygen from the air using physical separation technology. They are an indispensable piece of equipment in modern industrial production. Their core value lies in replacing the traditional method of purchasing bottled or liquid oxygen, allowing users to produce their required oxygen independently, continuously, and stably.
[0003] Currently, in the application of industrial oxygen generators, the compressed gas enters the tower through the inlet, carrying a significant amount of dust. Therefore, molecular sieves are used to intercept and purify this dust, thereby improving the overall oxygen production efficiency. However, over time, dust accumulates on the surface of the molecular sieves, causing blockages and hindering gas flow. Summary of the Invention
[0004] To address the issue of dust accumulation on the surface of molecular sieves during prolonged use, which can clog the sieves and impede gas flow, this application provides an industrial oxygen generator.
[0005] The industrial oxygen generator provided in this application adopts the following technical solution: An industrial oxygen generator includes an air compressor, an air storage tank, a first adsorption tower, a second adsorption tower, and an oxygen buffer tank. The output end of the air compressor is connected to a pipe (pipe 1). The end of pipe 1 away from the air compressor is fixed to the outer circumferential surface of the air storage tank. A second pipe is fixed to the outer circumferential surface of the air storage tank. Two third pipes are fixed to the outer circumferential surface of pipe 2. The ends of the two third pipes away from pipe 2 are respectively fixed to the bottom of the outer circumferential surfaces of the first and second adsorption towers. Each of the two third pipes is equipped with a valve (valve 1) and a pneumatic angle seat valve. A fourth pipe is fixed to the top of each of the first and second adsorption towers. The ends of the two fourth pipes are respectively fixedly connected to the top of the oxygen buffer tank. Molecular sieve stratification is provided inside both the first and second adsorption towers. The first and second adsorption towers have identical structures. A dust removal assembly for removing dust from the surface of the molecular sieve stratification is provided inside both the first and second adsorption towers.
[0006] By adopting the above technical solution, atmospheric pressure air enters the air compressor, and then the clean and compressed air flows into the air storage tank. The gas in the air storage tank flows in from the bottom of the first adsorption tower and flows upward through the molecular sieve stratification. Under high pressure, nitrogen, carbon dioxide and water vapor in the gas are adsorbed by the molecular sieve, and the unadsorbed oxygen flows from the top of the tower into the oxygen buffer tank. Then, the dust on the surface of the molecular sieve stratification is removed by the dust removal component, so that the gas can pass through the molecular sieve stratification.
[0007] Preferably, the molecular sieve layering includes a molecular sieve mesh disposed within the first adsorption tower. The outer peripheral surface of the molecular sieve mesh is spaced apart from the inner peripheral surface of the first adsorption tower. A fixing plate is rotatably mounted on the top of the outer peripheral surface of the molecular sieve mesh and is fixedly connected to the first adsorption tower. A support plate is rotatably mounted on the bottom of the outer peripheral surface of the molecular sieve mesh and is fixedly connected to the first adsorption tower. A motor is disposed on the bottom surface of the first adsorption tower, and the top of the motor output shaft is fixed to the bottom of the molecular sieve mesh. The dust removal assembly includes an adsorption block disposed around the molecular sieve mesh. The adsorption block has a cavity inside and multiple dust suction holes are provided on the side of the adsorption block near the molecular sieve mesh. A vacuum pumping assembly for evacuating the cavity is disposed on the adsorption block.
[0008] By adopting the above technical solution, the air extraction component is activated, which extracts the gas from the cavity, creating a negative pressure inside the cavity. This allows the dust on the surface of the molecular sieve mesh to be drawn into the cavity through the dust suction holes, thereby cleaning the dust on the surface of the molecular sieve mesh.
[0009] Preferably, the adsorption block has an air extraction chamber, and the top of the inner circumferential surface of the air extraction chamber has a through hole that communicates with the cavity. The air extraction assembly includes a piston that is slidably disposed vertically in the air extraction chamber, and the adsorption block is provided with a driving assembly for driving the piston to move vertically.
[0010] By adopting the above technical solution, the drive assembly is activated, and the drive assembly drives the piston to move vertically. When the piston moves downward, the piston draws the gas in the cavity into the suction chamber, creating a negative pressure in the cavity, thereby allowing dust to flow into the cavity through the dust suction hole.
[0011] Preferably, the driving assembly includes a rotating rod passing through the bottom surface of the suction chamber, the rotating rod being rotatably connected to the adsorption block, a movable rod being rotatably mounted on the bottom surface of the piston, the top end of the rotating rod being inserted into a groove, the bottom end of the movable rod being inserted into the groove, the movable rod being threadedly connected to the rotating rod, and a driving component for driving the rotating rod to rotate being provided on the support plate.
[0012] By adopting the above technical solution, the driving component is activated, which drives the rotating rod to rotate. The rotating rod drives the moving rod to move vertically, thereby causing the moving rod to drive the piston to move vertically.
[0013] Preferably, the driving component includes a first gear disposed at the bottom end of the rotating rod, and a second gear disposed on the molecular sieve mesh, the second gear meshing with the first gear.
[0014] By adopting the above technical solution, when the motor is started, the motor drives the molecular sieve mesh to rotate, which in turn drives gear two to rotate. Gear two drives gear one to rotate, which in turn drives gear one to rotate the rotating rod.
[0015] Preferably, a suction pipe is fixed to the bottom surface of the adsorption block, the suction pipe is connected to the cavity, the bottom end of the suction pipe passes through the bottom surface of the first adsorption tower, and a valve is provided on the suction pipe.
[0016] By adopting the above technical solution, when it is necessary to clean the dust in the cavity, valve two is opened, and the dust in the cavity is sucked out through the suction pipe, which facilitates the cleaning of the dust in the cavity.
[0017] Preferably, a striking block is hinged to the side of the adsorption block, the striking block can strike the outer peripheral surface of the molecular sieve mesh, a tension spring is fixed to the side of the striking block, and the end of the tension spring away from the striking block is fixed to the side of the adsorption block, and a pushing member is provided on the molecular sieve mesh to drive the striking block to rotate.
[0018] By adopting the above technical solution, when the molecular sieve mesh rotates, the molecular sieve mesh drives the pusher to move, which in turn pushes the striking block to rotate. When the pusher disengages from the striking block, the striking block strikes the molecular sieve mesh under the elastic force of the tension spring, causing the molecular sieve mesh to vibrate. The dust on the surface of the molecular sieve mesh is shaken up, which makes it easier for the dust suction holes to suck the dust into the cavity.
[0019] Preferably, the pushing member includes a driving block fixed to the outer peripheral surface of the molecular sieve mesh, and the driving block can drive the striking block to rotate.
[0020] By adopting the above technical solution, when the molecular sieve mesh rotates, the molecular sieve mesh drives the driving block to rotate, thereby driving the striking block to rotate.
[0021] Preferably, the inner wall of the cavity is fixed with a plurality of guide plates, and two vertically adjacent guide plates are arranged with the dust suction holes spaced apart.
[0022] By adopting the above technical solution, when the piston moves upward, the piston pushes the gas in the suction chamber through the through hole into the cavity, causing the gas in the cavity to flow downward, thereby blowing the dust in the cavity to the bottom of the cavity.
[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. Atmospheric air enters the air compressor, and then the clean and compressed air flows into the air storage tank. The gas in the air storage tank flows in from the bottom of the first adsorption tower and flows upward through the molecular sieve. Under high pressure, nitrogen, carbon dioxide and water vapor in the gas are adsorbed by the molecular sieve. The unadsorbed oxygen flows from the top of the tower into the oxygen buffer tank. Then, the dust on the surface of the molecular sieve is removed by the dust removal component, so that the gas can pass through the molecular sieve. 2. When the molecular sieve mesh rotates, it drives the pusher to move, which in turn pushes the striking block to rotate. When the pusher disengages from the striking block, the striking block strikes the molecular sieve mesh under the elastic force of the tension spring, causing the molecular sieve mesh to vibrate. The dust on the surface of the molecular sieve mesh is shaken up, which makes it easier for the dust suction holes to suck the dust into the cavity. 3. When the piston moves upward, it pushes the gas in the suction chamber through the through hole into the cavity, causing the gas in the cavity to flow downward, thereby blowing the dust in the cavity to the bottom of the cavity.

A support plate 23 is fitted onto the bottom of the outer circumferential surface of the molecular sieve mesh 21, rotatably connected to it, and its outer circumferential surface is fixedly connected to the inner circumferential surface of the first adsorption tower 12. A motor 4 is fixed to the bottom of the first adsorption tower 12, with the top of the motor 4's output shaft fixed to the bottom of the molecular sieve mesh 21.
[0033] Reference Figure 2 and Figure 3 An adsorption block 3 is provided on the periphery of the molecular sieve mesh 21. The side of the adsorption block 3 away from the molecular sieve mesh 21 is fixedly connected to the inner peripheral surface of the first adsorption tower 12. A cavity 32 is formed inside the adsorption block 3. Multiple dust-absorbing holes 38 are formed on the side of the adsorption block 3 near the molecular sieve mesh 21. The multiple dust-absorbing holes 38 are arranged at equal intervals along the vertical direction. Multiple guide plates 39 are fixed to the inner wall of the cavity 32. The dust-absorbing holes 38 are arranged at intervals between two adjacent guide plates 39 along the vertical direction. The dust-absorbing holes 38 are located below the guide plates 39.
[0034] Reference Figure 2 and Figure 3 An air extraction chamber 31 is provided inside the adsorption block 3. A through hole 33 is provided at the top of the inner circumferential surface of the air extraction chamber 31, which is connected to the cavity 32. A piston 34 is vertically slidably arranged inside the air extraction chamber 31. A rotating rod 35 is inserted through the bottom surface of the air extraction chamber 31 and is rotatably connected to the adsorption block 3. A moving rod 37 is rotatably mounted on the bottom surface of the piston 34. An insertion groove 36 is provided at the top of the rotating rod 35. The bottom end of the moving rod 37 is inserted into the insertion groove 36 and is threadedly connected to the inner wall of the insertion groove 36. A gear 41 is fixedly fitted onto the bottom end of the rotating rod 35, and a gear 42 is fixedly fitted onto the outer circumferential surface of the molecular sieve mesh 21. The gear 42 meshes with the gear 41. A suction pipe 43 is fixed to the inner bottom surface of the cavity 32. The suction pipe 43 is connected to the cavity 32. The bottom end of the suction pipe 43 extends out of the bottom surface of the first adsorption tower 12. A valve 44 is fixed to the outer circumference of the suction pipe 43.
[0035] Reference Figure 1 and Figure 2 A striking block 5 is hinged to the side of the adsorption block 3, and a tension spring 51 is fixed to the side of the striking block 5. The end of the tension spring 51 away from the striking block 5 is fixed to the side of the adsorption block 3. Multiple driving blocks 52 are fixed to the outer peripheral surface of the molecular sieve mesh 21. The driving blocks 52 can drive the striking block 5 to rotate around the hinge point of the striking block 5.
[0036] The implementation principle of an industrial oxygen generator according to an embodiment of this application is as follows: the motor 4 is started, and the output shaft of the motor 4 drives the molecular sieve mesh 21 to rotate. The molecular sieve mesh 21 drives the driving block 52 to rotate around the central axis of the molecular sieve mesh 21, so that the driving block 52 drives the striking block 5 to rotate. When the driving block 52 disengages from the striking block 5, the striking block 5 rotates towards the direction close to the molecular sieve mesh 21 under the elastic force of the tension spring 51, so that the striking block 5 strikes the molecular sieve mesh 21, causing the molecular sieve mesh 21 to vibrate and shake up the dust on the surface of the molecular sieve mesh 21. When the molecular sieve mesh 21 rotates, it also drives gear 2 42 to rotate, which in turn drives gear 1 41 to rotate. Gear 1 41 drives rotating rod 35 to rotate, which in turn drives moving rod 37 to move vertically. Moving rod 37 then drives piston 34 to move vertically. When piston 34 moves downward, it draws gas from cavity 32 into suction chamber 31 through through hole 33, creating negative pressure in cavity 32. Dust agitated on the surface of molecular sieve mesh 21 is then drawn into cavity 32 through suction hole 38. When piston 34 moves upward... During movement, the gas in the extraction chamber 31 is discharged into the cavity 32 through the through hole 33, causing the gas in the cavity 32 to flow downward under the action of the guide plate 39, blowing the dust in the cavity 32 to the bottom of the cavity 32. When it is necessary to discharge the dust in the cavity 32, the valve 44 is opened and the dust is sucked out of the first adsorption tower 12 through the dust suction pipe 43, thereby cleaning the dust on the surface of the molecular sieve mesh 21, thereby reducing the dust clogging the pores on the surface of the molecular sieve mesh 21 and facilitating the gas to pass through the molecular sieve layer 2.
[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
