Description

Technical Field

[0001] This utility model relates to the field of natural gas purification technology, specifically to a catalyst replacement device for natural gas purification. Background Technology

[0002] Natural gas is a mixture of gases primarily composed of methane, typically found in underground rock reservoirs. It is a clean and efficient energy source, widely used in power generation, industrial fuel, city gas supply, and chemical feedstock. While methane is the main component of natural gas, it also contains small amounts of alkanes such as ethane, propane, and butane, as well as non-hydrocarbon gases like carbon dioxide, nitrogen, and hydrogen sulfide. Natural gas purification requires catalysts, which need to be replaced after prolonged use. However, most existing replacement devices are integrated designs, hindering catalyst replacement and impacting purification efficiency.

[0003] According to the description in the patent announcement of a distillation column catalyst replacement device (authorization announcement number: CN220213967U), the distillation column catalyst replacement device includes "column body components, upper shell, lower shell", etc., to carry out replacement work.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] The catalyst replacement device for this distillation column utilizes column components, upper shell, and lower shell to perform the replacement work. During use, the column components are disassembled to replace the catalyst, and workers need to remove the catalyst by hand. Direct contact with the catalyst can affect the safety and health of workers, resulting in poor replacement efficiency. Therefore, this device needs to be improved. Utility Model Content

A filter plate assembly is slidably connected inside the fixed frame, and a storage frame is slidably connected inside the fixed frame. A fixed block is fixedly connected to the top of the sealing gasket, and a connecting rod is fixedly connected to the front side of the fixed block. A moving plate is slidably connected to the periphery of the connecting rod, and an insertion rod is fixedly connected to the rear side of the moving plate. The insertion rod is slidably connected inside the fixed block, and the rear side of the insertion rod is inserted into the filter plate assembly. A first spring is sleeved around the periphery of the connecting rod.

[0009] A baffle is slidably connected inside the storage frame. A round rod is fixedly connected to the left side of the baffle. A connecting block is slidably connected to the outer periphery of the round rod. The connecting block is fixedly connected to the bottom of the partition. A pull ring is fixedly connected to the left side of the round rod. A second spring is sleeved around the outer periphery of the round rod.

[0010] Preferably, the fixed frame is slidably connected inside the purification box, the bottom of the filter plate assembly is in contact with the top of the partition, and the storage frame extends through the interior of the partition to facilitate the storage of the catalyst under the action of the storage frame.

[0011] Preferably, the bottom of the sealing gasket is in contact with the top of the purification box, and the fixing rod is slidably connected to the inside of the top plate, so that the fixed frame can move more stably under the action of the fixing rod.

[0012] Preferably, the front side of the first spring is fixedly connected to the rear side of the movable plate, the rear side of the first spring is fixedly connected to the front side of the fixed block, the left side of the second spring is fixedly connected to the right side of the pull ring, and the right side of the second spring is fixedly connected to the left side of the connecting block, so that the insertion rod and the baffle are in a stable state under the action of the first spring and the second spring.

[0013] Preferably, there are two insertion rods, which are fixedly connected to the rear side of the movable plate, and the rear sides of the two insertion rods are respectively inserted into the filter plate assembly and the storage frame, so as to limit the filter plate assembly and the storage frame respectively under the action of the insertion rods.

[0014] Preferably, the storage mechanism includes a support frame, which is fixedly connected to the rear side of the purification box.

[0016] Compared with the prior art, the present invention provides a catalyst replacement device for natural gas purification, which has the following advantages:

[0017] 1. This catalyst replacement device for natural gas purification, through its replacement mechanism, allows the fixed frame to be positioned inside the purification chamber when natural gas purification is required. Catalyst is then added to the storage box, allowing natural gas to enter the purification chamber through the inlet pipe. Purification then occurs under the combined action of the filter plate assembly and the catalyst. After purification, the gas is discharged through the exhaust pipe. The filter plate assembly and storage box are limited by a moving plate, a rod, and a first spring, facilitating their positioning, installation, disassembly, and cleaning. A baffle is slidably connected inside the storage box, limited by a round rod, a connecting block, a second spring, and a pull ring. When catalyst replacement is needed, the first cylinder moves the fixed frame, causing it to move the filter plate assembly and storage box to the top of the purification chamber, releasing the seal on the bottom of the storage box and improving replacement efficiency. When catalyst needs to be added to the storage box, it is added through the top of the storage box, and then sealed with an external sealing cap.

[0018] 2. The catalyst replacement device for natural gas purification, through its storage mechanism, allows for the replacement of catalyst during natural gas purification operations within the purification chamber, filter plate assembly, and storage frame, with the catalyst stored in the storage frame. When the fixed frame is at the top of the purification chamber, the second cylinder moves the storage box to the bottom of the storage frame, allowing the catalyst to be collected under the action of the storage box. This prevents direct contact between the catalyst and personnel, ensuring worker safety. Furthermore, the storage box is fixed in the mounting base with pins, facilitating installation, disassembly, and catalyst handling. Attached Figure Description

[0030] This utility model provides the following technical solution:

[0031] Example 1

[0032] Please see Figure 1-7 This utility model provides a technical solution: a catalyst replacement device for natural gas purification, including a purification box 1, an air inlet pipe 2 fixedly connected to the left side of the purification box 1, an exhaust pipe 5 fixedly connected to the right side of the purification box 1, a replacement mechanism 3 provided on the top of the purification box 1, and a storage mechanism 4 provided on the rear side of the purification box 1.

[0033] The replacement mechanism 3 includes a load-bearing frame 31, which is fixedly connected to the periphery of the purification box 1. A top plate 32 is fixedly connected to the top of the load-bearing frame 31. A first cylinder 33 is fixedly connected to the top of the top plate 32.

A fixed block 37 is fixedly connected to the top of the sealing gasket 35. A connecting rod 394 is fixedly connected to the front side of the fixed block 37. A moving plate 393 is slidably connected to the periphery of the connecting rod 394. An insertion rod 396 is fixedly connected to the rear side of the moving plate 393. The insertion rod 396 is slidably connected inside the fixed block 37. The rear side of the insertion rod 396 is inserted into the interior of the filter plate assembly 38. A first spring 395 is sleeved around the periphery of the connecting rod 394.

[0034] A baffle 392 is slidably connected inside the storage box 39. A round rod 399 is fixedly connected to the left side of the baffle 392. A connecting block 391 is slidably connected to the outside of the round rod 399. The connecting block 391 is fixedly connected to the bottom of the partition 3992. A pull ring 397 is fixedly connected to the left side of the round rod 399. A second spring 398 is sleeved around the outside of the round rod 399. A limit rod 3991 is fixedly connected to the left side of the baffle 392. The limit rod 3991 is slidably connected inside the connecting block 391.

[0035] The fixed frame 36 is slidably connected inside the purification box 1. The bottom of the filter plate assembly 38 is in contact with the top of the partition 3992. The storage frame 39 passes through the interior of the partition 3992, facilitating the storage of the catalyst. The bottom of the sealing gasket 35 is in contact with the top of the purification box 1. The fixing rod 34 is slidably connected inside the top plate 32, facilitating more stable movement of the fixed frame 36 under the action of the fixing rod 34. The front side of the first spring 395 is fixedly connected to the rear side of the moving plate 393, and the rear side of the first spring 395 is fixedly connected to the front side of the fixing block 37. The second spring 398 is fixedly connected to the right side of the pull ring 397 on the left side, and the second spring 398 is fixedly connected to the left side of the connecting block 391 on the right side, so that the insertion rod 396 and the baffle 392 are in a stable state under the action of the first spring 395 and the second spring 398. There are two insertion rods 396, which are fixedly connected to the rear side of the moving plate 393 respectively, and the rear side of the two insertion rods 396 are respectively inserted into the filter plate group 38 and the storage frame 39, so that the filter plate group 38 and the storage frame 39 are respectively limited under the action of the insertion rods 396.

[0036] Example 2

[0037] Please see Figure 1-7 Furthermore, based on Embodiment 1, the storage mechanism 4 further includes a support frame 41, which is fixedly connected to the rear side of the purification box 1. A second cylinder 42 is fixedly connected to the rear side of the support frame 41, and a mounting base 43 is fixedly connected to the front side of the second cylinder 42. A storage box 45 is inserted into the mounting base 43, and a pin 44 is inserted into the storage box 45. The pin 44 passes through the interior of the mounting base 43. Fixing grooves are respectively opened inside the storage box 45 and the mounting base 43, and the two fixing grooves correspond to each other. The pin 44 is inserted into the fixing groove, so that the storage box 45 is in a stable state under the action of the pin 44.

[0038] In actual operation, when this device is used and natural gas needs to be purified, the fixed frame 36 is placed inside the purification box 1, and a catalyst is added to the storage box 39. Natural gas enters the purification box 1 through the inlet pipe 2, and purification is carried out under the dual action of the filter plate assembly 38 and the catalyst. After purification, the gas is discharged through the exhaust pipe 5. When the filter plate assembly 38 and the storage box 39 need to be cleaned, the moving plate 393 is pulled forward, which moves the insertion rod 396 and causes the first spring 395 to deform, thereby releasing the limit on the filter plate assembly 38 and the storage box 39 and allowing for cleaning.

[0039] When the catalyst needs to be replaced after prolonged use, the first cylinder 33 moves the fixed frame 36, which in turn moves the filter plate assembly 38 and the storage frame 39. The fixed frame 36 also causes the fixed rod 34 to slide inside the top plate 32, positioning the filter plate assembly 38 and the storage frame 39 at the top of the purification chamber 1. Simultaneously, the second cylinder 42 moves the storage box 45 to the bottom of the storage frame 39. Pulling the pull ring 397 to the left moves the round rod 399 and the baffle 392, causing the baffle 392 to slide the limiting rod 3991 inside the connecting block 391. This causes the second spring 398 to deform, releasing the baffle 392 from its limiting position on the bottom of the storage frame 39. This allows the catalyst to enter the storage box 45 from the storage frame 39 for collection, preventing direct contact between the catalyst and personnel and ensuring worker safety.

[0040] When collection is complete, release the pull ring 397, and the second spring 398 will reset, allowing the bottom of the storage frame 39 to be resealed under the action of the baffle 392. Under the action of the first cylinder 33, the fixed frame 36, the filter plate assembly 38, and the storage frame 39 will be moved back into the purification box 1. New catalyst can then be added to the top of the storage frame 39. The storage box 45 is fixed in the mounting base 43 by the pin 44, facilitating the installation and disassembly of the storage box 45 and the processing of the catalyst.
