Description

Technical Field

[0001] This invention relates to the field of adsorption equipment technology, specifically to a self-priming pressure swing adsorption device using solid packing particles. Background Technology

[0002] Pressure swing adsorption (PSA) equipment typically consists of adsorption cylinders or towers, separation packing, and switching valves. The separation packing, filled within the adsorption cylinders or towers, is composed of solid granules. Depending on the separation medium, its material, shape, size, and density vary, but it is often cylindrical or spherical. When the separation capacity of the PSA packing decreases or reaches its designed service life, it needs to be replaced.

[0003] In existing technologies, the unloading of the separation packing material is mainly divided into two types depending on the pressure swing adsorption (PSA) equipment: manual unloading with a discharge port and manual material removal in confined spaces without a discharge port. Manual unloading is inefficient and generates a large amount of dust during operation, some of which is released into the atmosphere and some is inhaled by workers, causing significant harm. Therefore, we propose a self-priming pressure swing adsorption (PSA) device using solid packing particles. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a self-priming pressure swing adsorption (PSA) device for solid packing particles. This solves the problem that, depending on the type of PSA device, there are two main unloading methods when discharging the packing material: manual unloading with a discharge port and manual material removal in confined spaces without a discharge port. Manual unloading is inefficient and generates a large amount of dust during operation, some of which is released into the atmosphere and some is inhaled by workers, causing significant harm to them.

[0026] This invention provides a self-priming pressure swing adsorption (PSA) device using solid packing particles. Compared with existing technologies, it has the following advantages:

[0027] 1. This solid packing particle self-priming pressure swing adsorption equipment adopts the principle of pneumatic conveying to form the suction structure. It uses an air pump as the power source and provides air supply to the pneumatic suction pump through the first air pipe. With the suction head and suction pipe, it can directly extend into the adsorption tower to complete the suction of the packing. There is no need for manual handling and dumping of the packing throughout the process. The dust filter and filter cartridge can filter the dust-laden airflow generated during the suction process to prevent dust from splashing around and being inhaled by workers, thus improving safety.

[0028] 2. This solid packing particle self-priming pressure swing adsorption equipment uses a drive motor to drive a gear and an external gear ring to mesh and drive the rotating sleeve and filter cartridge to rotate at a constant speed. With the help of a fixed cleaning pipe and multiple sets of back-blowing nozzles, it can perform uniform pulse back-blowing to clean the surface of the filter cartridge. At the same time, the power of the rotating shaft synchronously drives the swing component, which converts the rotational motion into reciprocating oscillation through the cooperation of the cylinder and the transmission groove. This drives multiple sets of striking rods to periodically strike the outer wall of the filter cartridge, which can shake off the dust embedded in the pores of the filter cartridge. It can effectively remove the dust accumulation on the filter cartridge and enhance the subsequent filtration effect.

[0029] 3. This solid packing particle self-priming pressure swing adsorption device achieves rapid assembly and disassembly of the filter cartridge through the design of the plug-in assembly and transmission assembly. When disassembling the filter cartridge, simply press the push block to disengage the plug rod from the slot to unlock it. Pushing the sliding seat drives the rotating ring to rotate, which in turn drives the multiple sets of plug-in blocks in the ring array to retract through the inclined transmission of the connecting groove and the connecting column, thereby releasing the locking state of the filter cartridge. During installation, after inserting the filter cartridge into the rotating sleeve, release the sliding seat. Under the elastic force of the first spring, the plug-in block moves back to its original position and locks into the plug-in groove of the filter cartridge, completing the installation. The assembly and disassembly efficiency is higher and the operation is more convenient. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1 to 12 The present invention provides a technical solution:

[0051] A self-priming pressure swing adsorption (PSA) device for solid filler particles includes a silo 1 and an air pump 2. A suction pipe 11 is fixedly connected to the outside of the silo 1. A pneumatic suction pump 12 is fixedly connected to the end of the suction pipe 11 furthest from the silo 1. A suction head 13 is provided at one end of the pneumatic suction pump 12. A second air pipe 22 and a first air pipe 21 are provided externally to the air pump 2. The first air pipe 21 is connected to the pneumatic suction pump 12 to provide an air source for the pneumatic suction pump 12. An inductive switch is provided on the inner wall of the silo 1, and a [missing information - likely a device name or component] is fixedly connected to the top of the silo 1. The dust filter 3 has a rotating sleeve 4 inside, and a filter cylinder 31 inside the rotating sleeve 4. The filter cylinder 31 extends into the interior of the dust filter 3. The rotating sleeve 4 has a plug-in assembly for fixing the filter cylinder 31. A cleaning tube 33 is fixedly connected to the inner wall of the dust filter 3. Multiple back-blowing nozzles are provided on the outside of the cleaning tube 33 for cleaning the filter cylinder 31. The dust filter 3 has a knocking assembly inside for knocking off the dust on the filter cylinder 31.

[0052] In this scheme, the suction head 13 is placed in the granular packing inside the tower body, the air pump 2 is started, and the air pump 2 provides air to the pneumatic suction pump 12. The air pressure is adjusted to 0.7MPa by the pressure regulating valve 24. The suction switch is pressed, and the pneumatic suction pump 12 automatically sucks the material into the hopper 1. When the granular packing in the hopper 1 reaches the limit position, the induction switch on the inner wall of the hopper 1 sends a stop signal to the air pump 2 to cut off the air supply of the pneumatic suction pump 12 and stop the suction. The filter cartridge 31 can be quickly installed and disassembled by the plug-in component.

[0053] When the filter cartridge 31 needs to be cleaned, gas is delivered to the cleaning pipe 33 through the second air pipe 22 and the pneumatic pulse valve 23, and sprayed out through the back-blowing nozzle outside the cleaning pipe 33 to blow the filter cartridge 31 and ensure the filtration effect of the filter cartridge 31. The filter cartridge 31 can be knocked by the setting of the knocking component, thereby shaking off the dust and other adhering objects on the filter cartridge 31.

[0054] like Figure 1 and Figure 3 As shown: In this scheme, a pressure regulating valve 24 is installed on the outside of the first air pipe 21, the second air pipe 22 is connected to the cleaning pipe 33, and a pneumatic pulse valve 23 is provided on the outside of the second air pipe 22.

[0055] In this design, the pressure during material suction can be adjusted by the pressure regulating valve 24, and the gas can be delivered to the cleaning pipe 33 by the second air pipe 22 and the pneumatic pulse valve 23, which facilitates the cleaning of the filter cartridge 31.

[0056] like Figure 4 and Figure 6 As shown: In this scheme, the dust filter 3 is provided with a rotating assembly for driving the rotating sleeve 4 to rotate. The rotating assembly includes multiple rotating shafts 54 that are rotatably connected in a ring array inside the dust filter 3. Gears 53 are fixedly connected to the outside of the rotating shafts 54, and an external gear ring 41 is fixedly connected to the outside of the rotating sleeve 4. The gears 53 and the external gear ring 41 are meshed together. A drive motor 32 is fixedly connected to the top of the dust filter 3, and one of the rotating shafts 54 is fixedly connected to the output end of the drive motor 32. A discharge port 14 is fixedly connected to the bottom of the hopper 1.

[0057] In this scheme, the drive motor 32 drives one of the rotating shafts 54 to rotate. The rotating shaft 54 ​​drives the outer gear ring 41 to rotate through the gear 53. The outer gear ring 41 drives the rotating sleeve 4 and the filter cylinder 31 to rotate, so that the back-blowing nozzle outside the cleaning pipe 33 can clean different positions of the filter cylinder 31. The packing material in the hopper 1 can be discharged through the setting of the discharge port 14.

[0058] like Figure 6 and Figure 8 As shown: In this solution, the striking component includes multiple drive shafts 51 rotatably connected in a ring array inside the dust filter 3. Multiple striking rods 5 are fixedly connected in a linear array outside the drive shafts 51 for striking and shaking off the dust on the filter cartridge 31. The dust filter 3 is provided with a swing component for driving the drive shafts 51 to swing. The swing component includes a connecting frame 52 fixedly connected to the outside of the drive shafts 51. The connecting frame 52 has a transmission groove 57 inside. One end of the rotating shaft 54 ​​is fixedly connected to a support block 55. A cylinder 56 is fixedly connected to the side of the support block 55 near the connecting frame 52 for driving the connecting frame 52 to swing.

[0059] In this design, the rotation of the external gear ring 41 drives the other two gears 53 to rotate, which in turn drives the other two rotating shafts 54 to rotate. The rotating shafts 54 drive the cylinder 56 to rotate through the support block 55, so that the cylinder 56 cooperates with the transmission groove 57. When the cylinder 56 rotates, it squeezes and drives the connecting frame 52 to swing. The connecting frame 52 drives the striking rod 5 to swing through the transmission shaft 51, so that the striking rod 5 strikes the filter cartridge 31, which can shake off the dust and other particles attached to the filter cartridge 31 and improve the cleaning effect of the filter cartridge 31.

[0060] like Figure 9 , Figure 10 and Figure 12 As shown: In this solution, the plug-in assembly includes multiple plug-in blocks 42 that are slidably connected in a ring array inside the rotating sleeve 4. The plug-in blocks 42 extend to the outside of the rotating sleeve 4. The outside of the filter cylinder 31 is provided with multiple plug-in slots 34 in a ring array. The plug-in blocks 42 are movably plugged into the plug-in slots 34. A first spring 44 is provided between the plug-in blocks 42 and the rotating sleeve 4. One end of the first spring 44 abuts against the plug-in blocks 42. Multiple guide rods 43 are fixedly connected to the inner wall of the rotating sleeve 4. The plug-in blocks 42 are slidably sleeved on the guide rods 43. The inside of the rotating sleeve 4 is provided with a transmission assembly for driving the multiple plug-in blocks 42 to move synchronously. The transmission assembly includes a rotating ring 6 that is rotatably connected inside the rotating sleeve 4. The inside of the rotating ring 6 is provided with multiple connecting slots 61 in a ring array. A connecting post 46 is fixedly connected to the side of the plug-in block 42 near the rotating ring 6.

[0061] In this solution, when the filter cartridge 31 is disassembled, the rotation of the rotating ring 6 causes the connecting groove 61 to engage with the connecting post 46. As the rotating ring 6 rotates, it squeezes and drives the insertion block 42 to move. The first spring 44 is compressed, and the insertion block 42 moves away from the insertion groove 34, thereby releasing the locking state of the filter cartridge 31 and allowing the filter cartridge 31 to be removed.

[0062] When the filter cartridge 31 is installed, the first spring 44 will move and reset the insertion block 42 due to its elasticity, so that the insertion block 42 moves into the insertion groove 34, thereby locking the position of the filter cartridge 31.

[0063] like Figure 9 and Figure 11 As shown: In this scheme, a sliding seat 62 is fixedly connected to the outside of the rotating ring 6, a push block 64 is slidably connected to the inner wall of the sliding seat 62, and an insert rod 63 is fixedly connected to the outside of the push block 64. The insert rod 63 extends to the outside of the sliding seat 62. Two slots 45 are opened inside the rotating sleeve 4. The insert rod 63 is movably inserted into the slots 45 to fix the position of the sliding seat 62. A limit rod 65 is fixedly connected to the inner wall of the sliding seat 62. The push block 64 is slidably sleeved on the limit rod 65. A second spring 66 is provided on one side of the push block 64. The second spring 66 is sleeved on the outside of the limit rod 65.

[0064] In this solution, when the filter cartridge 31 needs to be disassembled, push the push block 64, the second spring 66 is compressed, the push block 64 drives the insertion rod 63 to move and disengage from the slot 45, which can push the sliding seat 62, and the sliding seat 62 drives the rotating ring 6 to rotate.

[0065] When the filter cartridge 31 needs to be installed, the rotating ring 6 drives the sliding seat 62 to move to the initial position, the push block 64 is released, and the second spring 66 will drive the push block 64 to move and reset due to the elastic force. The push block 64 drives the insertion rod 63 to move into the slot 45, thereby locking the position of the sliding seat 62.

[0066] Working principle:

[0067] In use, place the suction head 13 into the granular packing inside the tower body, start the air pump 2 to provide air to the pneumatic suction pump 12, adjust the air pressure to 0.7MPa through the pressure regulating valve 24, press the suction switch, and the pneumatic suction pump 12 will automatically suck the material into the hopper 1. When the granular packing in the hopper 1 reaches the limit position, the sensor switch on the inner wall of the hopper 1 sends a stop signal to the air pump 2 to cut off the air supply of the pneumatic suction pump 12 and stop the suction. Manually open the discharge port 14 to discharge the granular packing, then close the discharge port 14 and repeat the above steps to suck the material. The dust generated during the suction is filtered by the filter cartridge 31 inside the dust filter 3 and then discharged into the atmosphere.

[0068] When the filter cartridge 31 needs to be cleaned, gas is delivered to the cleaning pipe 33 through the second air pipe 22 and the pneumatic pulse valve 23, and sprayed out through the back-blowing nozzle outside the cleaning pipe 33 to purge the filter cartridge 31 and ensure the filtration effect of the filter cartridge 31. The drive motor 32 is started, and the drive motor 32 drives one of the rotating shafts 54 to rotate. The rotating shaft 54 ​​drives the outer gear ring 41 to rotate through the gear 53. The outer gear ring 41 drives the rotating sleeve 4 and the filter cartridge 31 to rotate, so that the back-blowing nozzle outside the cleaning pipe 33 can clean different positions of the filter cartridge 31.

[0069] At the same time, the rotation of the external gear ring 41 will drive the other two gears 53 to rotate, which in turn will drive the other two rotating shafts 54 to rotate. The rotating shafts 54 drive the cylinder 56 to rotate through the support block 55, so that the cylinder 56 cooperates with the transmission groove 57. When the cylinder 56 rotates, it squeezes and drives the connecting frame 52 to swing. The connecting frame 52 drives the striking rod 5 to swing through the transmission shaft 51, so that the striking rod 5 strikes the filter cartridge 31, which can shake off the dust and other particles attached to the filter cartridge 31 and improve the cleaning effect of the filter cartridge 31.

[0070] When the filter cartridge 31 needs to be disassembled, push the push block 64, the second spring 66 is compressed, the push block 64 drives the insertion rod 63 to move away from the slot 45, which can push the sliding seat 62. The sliding seat 62 drives the rotating ring 6 to rotate, so that the connecting groove 61 and the connecting post 46 cooperate. Thus, when the rotating ring 6 rotates, it squeezes and drives the insertion block 42 to move. The first spring 44 is compressed, the insertion block 42 moves away from the insertion groove 34, and the locking state of the filter cartridge 31 can be released, so that the filter cartridge 31 can be removed.

[0071] When the filter cartridge 31 needs to be installed, place the filter cartridge 31 into the rotating sleeve 4, loosen the sliding seat 62, and the first spring 44 will move and reset the insertion block 42 due to its elastic force, so that the insertion block 42 moves into the insertion groove 34, thereby locking the position of the filter cartridge 31. At the same time, the movement and reset of the insertion block 42 will drive the rotating ring 6 to rotate and reset, and the rotating ring 6 will drive the sliding seat 62 to move to the initial position. Loosen the push block 64, and the second spring 66 will move and reset the push block 64 due to its elastic force. The push block 64 will drive the insertion rod 63 to move into the slot 45, thereby locking the position of the sliding seat 62. The operation is convenient.
