Description

Technical Field

[0001] The invention belongs to the technical field of unloading devices, and in particular relates to a hydrogenation catalyst unloading device. Background Art

[0002] Hydrogenation catalyst unloading is an important operation during the overhaul or replacement of hydrogenation units in the petrochemical industry and other industries. Hydrogenation catalysts are in the form of flakes. Flake hydrogenation catalysts are made by pressing catalyst raw materials into thin flakes. They have a relatively large specific surface area and can provide more active centers, which is beneficial to increasing the reaction rate.

[0003] When using a unloading device to unload and transport the flake hydrogenation catalyst to a designated location, an exhaust fan and a unloading pipe are usually used to unload and transport the flake hydrogenation catalyst in the hydrogenation reactor. However, during the transportation process, the flake catalyst is likely to contact the inner wall of the unloading pipe with a larger plane, increasing the contact area with the inner wall of the unloading pipe, thereby generating a larger friction force, making the catalyst easily adhere to the inner wall of the unloading pipe and not continue to be transported forward, hindering normal flow and transportation, and reducing the unloading speed of the flake hydrogenation catalyst. At the same time, the directions and positions of the unloading ports of different hydrogenation reactors are different. When it is necessary to unload the flake hydrogenation catalyst in the hydrogenation reactor, the staff also need to replace the corresponding connecting pipe according to the direction and position of the unloading port of the hydrogenation reactor, so that the connecting pipe is connected to the unloading pipe, and then the flake hydrogenation catalyst can be unloaded.

[0037] The operating principle of the present invention is now described as follows:

[0038] In the present invention, when the sheet-shaped hydrogenation catalyst needs to be unloaded and transported, the first motor 44 is first controlled to start according to the position of the hydrogenation reactor discharge port, driving the rotating plate 43 to rotate. During the rotation of the rotating plate 43, the telescopic connecting pipe 45 is driven to rotate. After one end of the telescopic connecting pipe 45 corresponds to the hydrogenation reactor discharge port, the first motor 44 is controlled to be closed, and then the first electric telescopic rod 41 is controlled to start, driving the side plate 42 and the telescopic connecting pipe 45 to move upward, so that one end of the telescopic connecting pipe 45 and the hydrogenation reactor discharge port are in the same plane, and then the second electric telescopic rod 410 is controlled to start, pushing the upper connecting block 49 to move upward, thereby driving the telescopic connecting pipe 45 to extend, so that the mounting ring 47 contacts the outer wall of the hydrogenation reactor discharge port. , then use the mounting bolts 48 to fix the mounting ring 47 to the outer wall of the hydrogenation reactor, so that the telescopic connecting pipe 45 is connected to the discharge port of the hydrogenation reactor, completing the installation between the telescopic connecting pipe 45 and the discharge port of the hydrogenation reactor, and then control the exhaust fan 71 to start, and the flake catalyst in the hydrogenation reactor is drawn to the end of the discharge pipe 6 through the discharge pipe 6, the spring hose 46 and the telescopic connecting pipe 45, and then control the exhaust fan 73 to start, and the flake catalyst transported to the end of the discharge pipe 6 will be blown into the discharge pipe 72 by the exhaust fan 73, and finally discharged from the discharge pipe 72, completing the unloading and transportation of the flake catalyst. When the flake catalyst is transported in the discharge pipe 6, the first electric slide rail 82 is controlled to drive the first slide plate 83 to move in the direction of the flake catalyst transportation, and the first slide plate 83 is driven to move in the direction of the flake catalyst transportation. During the movement of the plate 83, the detection ring 84 will be driven to move. At this time, the third electric telescopic rod 86 is controlled to start, driving the X-ray fluorescence spectrometer 87 to approach the inner wall of the discharge pipe 6. Then, the X-ray fluorescence spectrometer 87 is controlled to start to detect the inner wall of the discharge pipe 6. When it is detected that there is a sheet catalyst attached to the inner wall of the discharge pipe 6, the detection ring 84 is controlled to stop moving. Then, the fourth electric telescopic rod 89 is controlled to start, driving the fixed plate 810 to move, so that the fixed plate 810 is close to the inner wall of the discharge pipe 6. Then, the fifth electric telescopic rod 811 is controlled to start, driving the plug-in plate 812 to move, so that the plug-in plate 812 is close to the attached sheet catalyst. By controlling the fifth electric telescopic rod 811 and the fourth electric telescopic rod 89, the plug-in plate 812 is moved from the edge of the sheet catalyst to the inner wall of the discharge pipe 6. The sheet catalyst contacts, and as the plug plate 812 is inserted, a small part of the edge of the sheet catalyst will be lifted up. At this time, multiple blowers 814 are controlled to start and blow air to the sheet catalyst. The sheet catalyst under the blowing force will break away from the contact with the discharge pipe 6 and move in the conveying direction. At this time, the detection ring 84 is controlled to continue to move to detect and process the sheet catalyst at other positions. When the detection ring 84 moves to the very end of the discharge pipe 6, the detection ring 84 is controlled to return to its original position and then move in the conveying direction of the sheet catalyst again. During the movement of the detection ring 84 to return to its original position, the X-ray fluorescence spectrometer 87 is also controlled to return to its original position, and the sheet catalyst is not detected and processed. In the process of the detection ring 84 moving back and forth, the air pump 94 is controlled to start.The air pump 94 will discharge air into the connecting pipe 95 and finally be discharged from the air outlet 96. The air in the connecting pipe 95 will be transported to the connecting shell 97 and finally discharged from the air outlet 98. At this time, the air will be blown in different directions in the area formed by the connecting pipe 95 and the connecting shell 97, causing air turbulence. At the same time, the second electric slide rail 92 is controlled to drive the multiple second slide plates 93 to move continuously, so that the connecting pipe 95 and the connecting shell 97 rotate accordingly, so that the air blown out from the exhaust hole and the exhaust port can be blown evenly in this area. During the transportation process, the catalyst flakes are easily stuck together, which increases the volume and mass of the catalyst flakes and reduces the transportation efficiency. However, when the catalyst flakes pass through the area formed by the connecting pipe 95 and the connecting shell 97, the air in different directions will blow towards the stuck catalyst flakes, thereby separating the stuck catalyst flakes and facilitating faster transportation of the catalyst flakes. The air blowing gun 910 is controlled to start and push the catalyst flakes that have just passed through the detection ring 84 to the end of the discharge pipe 6 more quickly, so that the catalyst flakes can be unloaded and transported when it is necessary. During delivery, one end of the telescopic connecting pipe 45 is aligned with the discharge port of the hydrogenation reactor according to the position of the discharge port of the hydrogenation reactor. Then, the second electric telescopic rod 410 is used to make the mounting ring 47 contact the outer wall of the discharge port of the hydrogenation reactor. The mounting ring 47 is fixed to the outer wall of the hydrogenation reactor using the mounting bolt 48, so that the telescopic connecting pipe 45 is connected to the discharge port of the hydrogenation reactor, which facilitates the unloading of the sheet-shaped hydrogenation catalyst and avoids the need for workers to replace the corresponding connecting pipes according to the direction and position of the discharge port of the hydrogenation reactor. At the same time, the X-ray fluorescence spectrometer 87 can be used to detect whether the inner wall of the discharge pipe 6 is adhered to the sheet-shaped catalyst. Then, the plug plate 812 and the blower 814 are used to separate the sheet-shaped catalyst from the discharge pipe 6 and move it in the delivery direction to prevent the catalyst from adhering to the inner wall of the discharge pipe 6 and hindering normal flow and delivery. The air outlet 96 and the air outlet 98 can also be used to separate the sheet-shaped catalyst from each other, facilitating faster delivery of the sheet-shaped catalyst, thereby greatly improving the efficiency and reliability of the unloading of the sheet-shaped hydrogenation catalyst. ,
