Description

Technical Field

[0001] The present invention belongs to the technical field of discharging devices, and particularly relates to a discharging device for hydrogenation catalysts. Background Art

[0002] The discharging of hydrogenation catalysts is an important operation in the overhaul or catalyst replacement process of hydrogenation units in industries such as petrochemical industry. Among the forms of hydrogenation catalysts, there are flake-shaped ones. The flake-shaped hydrogenation catalysts are pressed from catalyst raw materials into thin sheet shapes. They have a relatively large specific surface area, can provide more active centers, and are beneficial to improving the reaction rate.

[0003] When using a discharging device to discharge and transport flake-shaped hydrogenation catalysts to a designated position, usually a suction fan and a discharging pipe are used to discharge and transport the flake-shaped hydrogenation catalysts in the hydrogenation reactor. However, during the transportation process, the flake-shaped catalysts are prone to contact the inner wall of the discharging pipe with a large plane, increasing the contact area with the inner wall of the discharging pipe, thereby generating a large frictional force, making the catalysts easily adhere to the inner wall of the discharging pipe and not continue to move forward, hindering the normal flow and transportation, reducing the discharging speed of the flake-shaped hydrogenation catalysts. At the same time, the opening directions and positions of the discharging ports of different hydrogenation reactors are different. When it is necessary to discharge the flake-shaped hydrogenation catalysts in the hydrogenation reactor, the staff also needs to replace the corresponding connecting pipes according to the opening directions and positions of the discharging ports of the hydrogenation reactor to make the connecting pipes communicate with the discharging pipe, and then the flake-shaped hydrogenation catalysts can be discharged. The steps are complex, greatly reducing the discharging efficiency and reliability of the flake-shaped hydrogenation catalysts.

[0023] In the embodiment, the acceleration assembly 9 includes a fifth groove 91 formed in the inner wall of the detection ring 84. The inner wall of the fifth groove 91 is fixedly connected with a second electric slide rail 92. A plurality of second sliding plates 93 are slidably connected to the side wall of the second electric slide rail 92.

[0024] Specifically, the air outlet holes 96 and the air outlet openings 98 can be used to separate the mutually adhered flaky catalysts, which is convenient for the faster conveying of the flaky catalysts, and greatly improves the efficiency and reliability of discharging the flaky hydrogenation catalyst.

[0025] Now, the operation principle of the present invention is described as follows: In the present invention, when it is necessary to unload and convey the flaky hydrogenation catalyst, first, the first motor 44 is controlled to start according to the position where the discharge port of the hydrogenation reactor is opened, driving the rotating plate 43 to rotate. During the rotation of the rotating plate 43, the telescopic connecting pipe 45 will be driven to rotate. After one end of the telescopic connecting pipe 45 corresponds to the discharge port of the hydrogenation reactor, the first motor 44 is controlled to stop. 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 is in the same plane as the discharge port of the hydrogenation reactor. 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 discharge port of the hydrogenation reactor. Then, the mounting ring 47 is fixed to the outer wall of the hydrogenation reactor by using the mounting bolts 48, so that the telescopic connecting pipe 45 communicates with the discharge port of the hydrogenation reactor, completing the installation between the telescopic connecting pipe 45 and the discharge port of the hydrogenation reactor. Then, the exhaust fan 71 is controlled to start, and the flaky catalyst in the hydrogenation reactor is pumped to the end of the discharge pipe 6 through the discharge pipe 6, the spring hose 46 and the telescopic connecting pipe 45. Then, the air outlet fan 73 is controlled to start, and the flaky catalyst transported to the end of the discharge pipe 6 will be blown into the discharge pipe 72 by the air outlet fan 73 and finally discharged from the discharge pipe 72, completing the unloading and conveying of the flaky catalyst. When the flaky catalyst is conveyed in the discharge pipe 6, the first electric slide rail 82 is controlled to drive the first slide plate 83 to move in the conveying direction of the flaky catalyst. During the movement of the first slide 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 the inner wall of the discharge pipe 6 is attached with flaky catalyst, the detection ring 84 is controlled to stop moving. Then, the fourth electric telescopic rod 89 is controlled to start, driving the fixing plate 810 to move, so that the fixing plate 810 approaches the inner wall of the discharge pipe 6. Then, the fifth electric telescopic rod 811 is controlled to start, driving the plug board 812 to move, so that the plug board 812 approaches the attached flaky catalyst. By controlling the fifth electric telescopic rod 811 and the fourth electric telescopic rod 89, the plug board 812 contacts the flaky catalyst from the edge of the flaky catalyst. At this time, as the plug board 812 is inserted, a small part of the edge of the flaky catalyst will be lifted. At this time, a plurality of hair dryers 814 are controlled to start to blow air to the flaky catalyst. The flaky catalyst affected by 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 flaky catalyst at other positions. When the detection ring 84 moves to the end of the discharge pipe 6, the detection ring 84 is controlled to return to its original position and then move again in the conveying direction of the flaky catalyst. During the movement of the detection ring 84 back to its original position, the X-ray fluorescence spectrometer 87 is also controlled to return to its original position and does not detect the flaky catalyst. And during the back-and-forth movement of the detection ring 84, the air pump 94 is controlled to start,The air pump 94 will discharge air into the connecting pipe 95 and finally discharge it from the air outlet hole 96. Moreover, the air in the connecting pipe 95 will be conveyed into the connecting shell 97 and finally discharged from the air outlet 98. At this time, the air in different directions will blow in the area formed by the connecting pipe 95 and the connecting shell 97, causing air turbulence. At the same time, control the second electric slide rail 92 to drive multiple second sliding plates 93 to move continuously, so that the connecting pipe 95 and the connecting shell 97 rotate accordingly, enabling the air blown out from the exhaust holes and the air outlet to blow evenly in this area. Since the flaky catalysts are prone to sticking together during the conveying process, it will increase the volume and mass of the flaky catalysts and reduce the conveying efficiency. However, when the flaky catalysts 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 flaky catalysts, so that the mutually stuck flaky catalysts are separated, facilitating the faster conveying of the flaky catalysts. And control the air blowing gun 910 to start, pushing the flaky catalysts that have just passed through the inside of the detection ring 84 to be conveyed faster towards the end of the discharge pipe 6. When it is necessary to discharge and convey the flaky hydrogenation catalysts, one end of the telescopic connecting pipe 45 can be made to correspond to the discharge port of the hydrogenation reactor according to the position of the discharge port of the hydrogenation reactor. Then, use the second electric telescopic rod 410 to make the mounting ring 47 contact the outer wall of the discharge port of the hydrogenation reactor, and use the mounting bolts 48 to fix the mounting ring 47 to the outer wall of the hydrogenation reactor, making the telescopic connecting pipe 45 communicate with the discharge port of the hydrogenation reactor, facilitating the discharging of the flaky hydrogenation catalysts, and avoiding the need for the staff 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 there are flaky catalysts attached to the inner wall of the discharge pipe 6. Then, use the plug board 812 and the hair dryer 814 to separate the flaky catalysts from the contact with the discharge pipe 6 and move them in the conveying direction, avoiding the catalysts from adhering to the inner wall of the discharge pipe 6 and hindering the normal flow and conveying. It can also use the air outlet hole 96 and the air outlet 98 to separate the mutually stuck flaky catalysts, facilitating the faster conveying of the flaky catalysts, and greatly improving the efficiency and reliability of discharging the flaky hydrogenation catalysts.
