[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example: Please refer to Figures 1-4. This utility model provides a technical solution: an industrial catalyst purging device for easy observation, including a purging chamber 1, observation windows 2 fixedly connected to both sides of the purging chamber 1, a guide rail 4 fixedly connected to the inner side of the purging chamber 1, and a gas distribution pipe 5 fixedly connected to the top of the guide rail 4. It also includes a protective assembly 3, which is fixedly connected to both sides of the purging chamber 1. A searchlight 8 is fixedly connected to the top of the inner wall of the purging chamber 1, and a purging assembly 7 is slidably connected to the outer side of the guide rail 4. The purging chamber 1 is moved by casters at the bottom. 1. Move to the designated position after the large industrial catalyst is coated, then release the brake, and then use the hoisting equipment to place the large catalyst steadily in the purge chamber 1. Connect the air source to the outside of the air distribution pipe 5, and use the purge assembly 7 to purge the catalyst. At the same time, turn on the searchlight 8. The searchlight 8 is a flicker-free LED light that can provide uniform and sufficient lighting in the purge chamber 1, eliminate shadows, and provide a clear and bright field of vision for manual visual inspection of the blockage. After the staff opens the protective assembly 3, they can observe the situation in the purge chamber 1 through the observation window 2.
[0024] The purging assembly 7 includes an air knife 71, with air guide shells 72 rotatably connected to both sides of the air knife 71. A limit slider 73 is fixedly connected to the outer side of the air guide shell 72, and a servo motor 74 is fixedly connected to the bottom of the limit slider 73. A rubber pressure roller 75 is fixedly connected to the output end of the servo motor 74. Annular blocks 76 are fixedly connected to both sides of the air knife 71. The outer side of the air distribution pipe 5 is fixedly connected to the inner side of the purging chamber 1. A limit hole 6 is opened in the top wall of the guide rail 4. The inner side of the limit slider 73 is slidably connected to the outer side of the guide rail 4. The top of the air guide shell 72 is fixedly connected to the outer side of the air distribution pipe 5 through a pipe joint. The inner side of the annular block 76 is rotatably connected to the outer side of the air guide shell 72. The outer wall of the rubber pressure roller 75 is rolledly connected to the outer wall of the annular block 76. When using component 7, the position of the limiting slider 73 on the guide rail 4 can be adjusted by removing the bolt on the limiting slider 73. Then, the bolt can be screwed into the limiting hole 6 to limit it. Multiple sets of purging components 7 can also be installed on the guide rail 4 at the same time to meet the needs of large-scale purging. During the purging process, the airflow in the air distribution pipe 5 enters the air knife 71 through the air guide shell 72. Finally, the air blown out from the air knife 71 can blow onto the catalyst surface to complete the purging process. By starting the servo motor 74, it drives the rubber pressure roller 75 to rotate. During the rotation of the rubber pressure roller 75, it reverses through the friction ring block 76, which can adjust the deflection angle of the air knife 71. This can achieve all-round purging of the catalyst surface and effectively remove excess slurry.
[0025] The protective assembly 3 includes a limiting frame 31, a protective plate 32 slidably connected to the inner side of the limiting frame 31, a rubber cleaning plate 33 fixedly connected to the outer side of the protective plate 32, a buckle plate 34 rotatably connected to the bottom of the protective plate 32, tension springs 35 fixedly connected to both sides of the limiting frame 31, the outer side of the limiting frame 31 fixedly connected to both sides of the purge chamber 1, the outer side of the rubber cleaning plate 33 slidably connected to the outer side of the observation window 2, and the bottom end of the tension springs 35 fixedly connected to both sides of the protective plate 32. When observation is required, the protective plate 32 is moved along the limiting frame. When the frame 31 is pulled down, the staff can observe the interior of the purge chamber 1 through the observation window 2. At this time, the tension spring 35 is stretched, and the rubber cleaning plate 33 moves together with the protective plate 32. The rubber cleaning plate 33 can clean the observation window 2 during the movement, keeping the observation window 2 clean during use. Then, the buckle plate 34 is rotated to lock it at the bottom of the limit frame 31, which can fix the position of the protective plate 32. When the protective plate 32 is reset, it can also protect the observation window 2 and prevent it from being damaged by external forces.
[0026] In use, the purge chamber 1 is moved to the designated position after the large industrial catalyst is coated using the casters at the bottom of the purge chamber 1. Then, the brakes are released, and the large catalyst is placed steadily in the purge chamber 1 using hoisting equipment. An external air source is connected to the outside of the air distribution pipe 5, and the catalyst is purged using the purge assembly 7. At the same time, the searchlight 8 is turned on. The searchlight 8 is a flicker-free LED light that can provide uniform and sufficient lighting in the purge chamber 1, eliminate shadows, and provide a clear and bright field of vision for manual visual inspection of blocked holes. After opening the protective assembly 3, the staff can observe the situation inside the purge chamber 1 through the observation window 2.
[0027] When using the purging assembly 7, the position of the limiting slider 73 on the guide rail 4 can be adjusted by removing the bolt on the limiting slider 73, and then the bolt can be screwed into the limiting hole 6 to limit it. Multiple sets of purging assemblies 7 can also be installed on the guide rail 4 at the same time to meet the needs of large-scale purging.
[0028] During the purging process, the airflow in the air distribution pipe 5 enters the air knife 71 through the air guide shell 72, and finally the air blown out from the air knife 71 can blow onto the catalyst surface to complete the purging process. By starting the servo motor 74, it drives the rubber pressure roller 75 to rotate. During the rotation of the rubber pressure roller 75, it reverses through the friction ring block 76, which can adjust the deflection angle of the air knife 71. Thus, the catalyst surface can be purged in all directions, effectively removing excess slurry.
[0029] When observation is required, the protective plate 32 is pulled down along the limiting frame 31, allowing the staff to observe the interior of the purge chamber 1 through the observation window 2. At this time, the tension spring 35 is stretched, and the rubber cleaning plate 33 moves together with the protective plate 32. The rubber cleaning plate 33 can clean the observation window 2 during the movement, keeping the observation window 2 clean during use. Then, the buckle plate 34 is rotated to lock it at the bottom of the limiting frame 31, thus fixing the position of the protective plate 32. When the protective plate 32 is reset, it can also protect the observation window 2 from damage caused by external forces.
