[0001] This utility model relates to the technical field of hydrogenation reactors, specifically a liquid-phase hydrogenation synthesis reactor. Background Technology
[0002] A liquid-phase hydrogenation reactor is a device used in hydrogenation technology to carry out reactions in the liquid phase. In traditional hydrogenation technology, to ensure that the hydrogen required for the reaction is completely converted into the liquid phase, a large amount of hydrogen-rich recirculated gas is introduced into the reactor along with the feed. In liquid-phase hydrogenation reactors, crude oil is typically added. The main purpose of adding crude oil is to facilitate the liquid-phase hydrogenation process, during which hydrogen dissolves in the crude oil to meet the hydrogen requirements of the hydrogenation reaction.
[0003] Existing liquid-phase hydrogenation synthesis reactors typically have a feed pipe for placing crude oil. However, crude oil has a certain viscosity, and if it is not cleaned for a long time, impurities will adhere to it, which will also lead to waste of raw materials and poor performance.

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.
[0028] Example 1
[0029] Please see Figure 1-8 A liquid-phase hydrogenation synthesis reactor includes a liquid-phase hydrogenation reactor body 1 and a fixed frame 2 fixedly installed at the bottom of the liquid-phase hydrogenation reactor body 1. A feed pipe 3 is fixedly installed through the middle of the top of the liquid-phase hydrogenation reactor body 1, and semi-circular rings 4 are attached to the front and rear sides of the top of the feed pipe 3. The opposite sides of the semi-circular rings 4 are attached together. A scraping component 5 is provided above the top of the feed pipe 3, and a moving component 6 is installed near the left side of the top of the liquid-phase hydrogenation reactor body 1. The scraping component 5 can be used to scrape the inner wall of the feed pipe 3, and the moving component 6 can move the scraping component 5 to facilitate the scraping operation.
[0030] In this embodiment, the moving component 6 includes an L-shaped plate 61 fixedly installed at the top of the liquid phase hydrogenation reactor body 1 near the middle and a servo motor 62 fixedly installed at the top inner side of the L-shaped plate 61. A threaded rod 63 is fixedly installed at the output end of the servo motor 62, and the lower end of the threaded rod 63 is movably installed on the liquid phase hydrogenation reactor body 1. A threaded sleeve 64 is threadedly installed on the outer side of the threaded rod 63 near the upper end. An n-shaped rod 65 is provided on the right side of the threaded sleeve 64, and the right end of the n-shaped rod 65 is fixedly installed on the movable plate 51, which can drive the movable plate 51 to move back and forth up and down, thereby realizing the scraping operation of the circular scraper 59 on the inner cavity of the feed pipe 3.
[0031] Specifically, a fixing plate 651 is fixedly installed on the left end below the n-shaped rod 65, and the left side of the fixing plate 651 is fixedly installed on the threaded sleeve 64, which can drive the n-shaped rod 65 and the threaded sleeve 64 to move up and down synchronously.
[0032] Specifically, a sliding plate 641 is fixedly installed at the middle of the left side of the threaded sleeve 64, and a sliding rod 642 is slidably installed through the sliding plate 641. The lower end of the sliding rod 642 is fixedly installed on the liquid phase hydrogenation reactor body 1, and the upper end of the sliding rod 642 is fixedly installed on the top of the inner side of the L-shaped plate 61, which serves to guide and limit the movement of the threaded sleeve 64.
[0033] Specifically, a connecting plate 41 is fixedly installed on the bottom of the semicircular ring 4 near the opposite side, and a bolt 42 is threaded through the connecting plate 41. The output end of the bolt 42 is threadedly inserted into the outer wall of the feeding pipe 3, which serves to lock and position the semicircular ring 4.
[0034] In this embodiment: During use, the feed pipe 3 is used to feed materials into the inner cavity of the liquid phase hydrogenation reactor body 1. After feeding, the servo motor 62 can be started. When the servo motor 62 is running, it will drive the threaded rod 63 to rotate. When the threaded rod 63 rotates, it will drive the threaded sleeve 64 to move downward. When the threaded sleeve 64 moves downward, it will drive the n-shaped rod 65 to move downward through the fixed plate 651. When the n-shaped rod 65 moves downward, it will drive the movable plate 51 to move downward, which is conducive to the scraping of the raw material attached to the inner cavity of the feed pipe 3. After the scraping is completed, the reverse operation can be performed to move the movable plate 51 upward to restore its original position.
[0035] Example 2
[0036] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-2 , Figure 4 and Figure 7-8 The scraping assembly 5 includes a movable plate 51 positioned above the top of the feeding pipe 3 and a vertical plate 52 fixedly installed at the bottom of the movable plate 51 near the rear side. A screw 53 is threaded through the vertical plate 52, and a trapezoidal extrusion block 54 is movably installed at the front end of the screw 53. The top of the trapezoidal extrusion block 54 is slidably mounted on the movable plate 51, and trapezoidal blocks 55 are attached to both sides of the trapezoidal extrusion block 54. A snap-fit plate 56 is provided on the front side of the opposite side of each trapezoidal block 55, and the opposite side of the snap-fit plate 56 is fixed. A snap-fit rod 57 is installed, and a snap-fit block 58 is provided on the opposite side of the snap-fit plate 56. A snap-fit interface is opened on the snap-fit block 58 near the top. The opposite ends of the snap-fit rod 57 extend into the inner cavity of the snap-fit interface. A circular scraper 59 is fixedly installed at the bottom of the snap-fit block 58. The circular scraper 59 is located in the inner cavity of the semi-circular ring 4. The circular scraper 59 is designed to facilitate the scraping of raw materials adhering to the inner wall of the feeding pipe 3. At the same time, the circular scraper 59 can be disassembled and cleaned to avoid affecting the scraping effect after long-term use.
[0037] Specifically, a knob 531 is fixedly installed at the rear end of the screw 53 to facilitate the rotation of the screw 53.
[0038] Specifically, L-shaped rods 551 are fixedly installed on the opposite side of the trapezoidal block 55, and the front ends of the L-shaped rods 551 are fixedly installed on the adjacent snap-fit plates 56, which can drive the trapezoidal block 55 and the snap-fit plates 56 to move synchronously.
[0039] Specifically, each of the opposite sides of the snap-fit plate 56 is provided with a side plate 561, and the snap-fit plate 56 and the adjacent side plate 561 are elastically connected by a telescopic spring 562. A fixing block 563 is fixedly installed on the opposite side of the side plate 561 near the top. The opposite side of the fixing block 563 is fixedly installed on the movable plate 51, which facilitates the movement and restoration of the snap-fit plate 56.
[0040] In this embodiment: When the movable plate 51 moves downward, it will drive the circular scraper 59 to move downward. When the circular scraper 59 moves downward, it will scrape the raw material attached to the inner wall of the feeding pipe 3, thereby improving the utilization rate of the raw material. In addition, the circular scraper 59 can be disassembled and cleaned periodically. By rotating the knob 531, the screw 53 can be driven to rotate. When the screw 53 rotates, it will drive the trapezoidal extrusion block 54 to move forward. When the trapezoidal extrusion block 54 moves forward, it will extrude the trapezoidal blocks 55 on both sides. At this time, the trapezoidal blocks 55 will move in the opposite direction. When the trapezoidal blocks 55 move in the opposite direction, they will drive the locking plates 56 on both sides to move in the opposite direction through the adjacent L-shaped rod 551. When the locking plates 56 move in the opposite direction, they will extrude the adjacent telescopic spring 562. At the same time, they will also drive the locking rods 57 on both sides to move in the opposite direction, thereby moving away from the inner cavity of the locking interface. At this time, the locking and positioning of the locking block 58 can be released, and the circular scraper 59 can be disassembled and removed. After cleaning, the reverse operation can be performed to re-lock the circular scraper 59.
[0041] Working Principle: During operation, the feed pipe 3 feeds material into the inner cavity of the liquid-phase hydrogenation reactor body 1. After feeding, the servo motor 62 starts, driving the threaded rod 63 to rotate. The rotation of the threaded rod 63 causes the threaded sleeve 64 to move downwards. This downward movement of the threaded sleeve 64, via the fixed plate 651, causes the n-shaped rod 65 to move downwards. The downward movement of the n-shaped rod 65, in turn, causes the movable plate 51 to move downwards, facilitating the scraping of the material adhering to the inner cavity of the feed pipe 3. After scraping, the operation is reversed to allow the movable plate 51 to move upwards and return to its original position. The downward movement of the movable plate 51 causes the circular scraper 59 to move downwards, scraping the material adhering to the inner wall of the feed pipe 3 and improving the original material's appearance. In addition to improving material utilization, the circular scraper 59 can be disassembled and cleaned periodically. By rotating the knob 531, the screw 53 can be rotated. When the screw 53 rotates, it will drive the trapezoidal extrusion block 54 to move forward. When the trapezoidal extrusion block 54 moves forward, it will extrude the trapezoidal blocks 55 on both sides. At this time, the trapezoidal blocks 55 will move in the opposite direction. When the trapezoidal blocks 55 move in the opposite direction, they will drive the snap-fit plates 56 on both sides to move in the opposite direction through the adjacent L-shaped rod 551. When the snap-fit plates 56 move in the opposite direction, they will extrude the adjacent telescopic spring 562. At the same time, they will also drive the snap-fit rods 57 on both sides to move in the opposite direction, thus moving them away from the inner cavity of the snap-fit interface. At this time, the snap-fit positioning of the snap-fit block 58 can be released, and the circular scraper 59 can be disassembled and removed. After cleaning, the reverse operation can be performed to re-snap the circular scraper 59.
