Abstract
Description
Technical Field
[0001] The invention relates to the technical field of stirring, in particular to a hydrogen absorption stirring device for a hydrogenation kettle. Background Art
[0002] The hydrogenation kettle absorbs hydrogen from the hydrogen inlet into the hollow tube of the stirring shaft, then discharges the hydrogen from the hydrogen inlet near the bottom, and then absorbs hydrogen from the hydrogen inlet again, repeating this cycle to achieve high hydrogen utilization. Using a hydrogen absorption and stirring device to centrally absorb hydrogen is more effective and efficient. However, the hydrogenation kettle needs to operate for long periods of time, so using a device with better hydrogen absorption is also a guarantee for equipment operation. If the hydrogen absorption effect is poor, it will result in hydrogen waste, increased costs, and reduced output. Therefore, a new solution is urgently needed to solve the above technical problems. Summary of the Invention
[0003] To address the aforementioned issues, the present invention discloses a hydrogen absorption and stirring device for a hydrogenation reactor, comprising a hub, with a plurality of arcuately curved blades fixedly connected to the sidewall of the hub at equal angles. The sidewall of the hub is provided with a plurality of openings. During use, the device is mounted on a hollow shaft and rotated in the direction of the circular motion of the blades. During the stirring process, hydrogen enters the hollow shaft through the openings and is collected.
[0004] The blades are each equipped with connecting plates at their upper and lower ends, which are sleeved and fixed to the sidewalls of the hub. Several triangular plates are positioned at equal angles along the radial edges of the connecting plates, with one side of the triangular plate being curved to align with the blade. The connecting plates are circular and have triangular plates on them, forming a semi-enclosed structure, allowing hydrogen to accumulate more easily between the two connecting plates, thereby improving hydrogen collection efficiency.
[0005] Preferably, a threaded hole is provided on the side wall of the hub. When the device is mounted on the hollow shaft, a hexagon socket bolt is threadedly provided in the threaded hole, and the hexagon socket bolt is tightened to radially press against the hollow shaft, thereby achieving axial fixation of the device on the hollow shaft.
[0006] Preferably, a keyway is provided on the inner wall of the hub, and a flat key is provided in the keyway. The flat key matching method is a common shaft matching method.
[0007] Preferably, a through hole is provided at the bottom of the flat key, in which a fixing bolt is threadedly provided. The fixing bolt has the same function as the hexagon socket bolt and is provided at the bottom of the flat key, thereby preventing the flat key from moving axially and supporting the propeller hub, thereby enhancing the fixing effect of the propeller hub.
[0008] The present invention has the following significant effects: By using a hydrogen absorption and stirring device that collects hydrogen in the same direction as the rotation, it is possible to prevent excessive dispersion of hydrogen during equipment operation, preventing the effective absorption of hydrogen from the hydrogen absorption port. The hydrogenation kettle requires long periods of operation, and by using a hydrogen collection method, hydrogen dispersion is reduced, which prevents the desired absorption of more hydrogen from the hydrogen absorption port, significantly improving the performance and stability of the equipment. This results in improved performance, stable operation, reduced enterprise investment costs, and increased productivity. Furthermore, the present device has a simple structure and is easy to manufacture, install, and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.
[0016] like Figures 1 to 4 As shown, a hydrogen absorption and stirring device for a hydrogenation kettle includes a hub 2, which is a cylindrical pipe. A plurality of blades 1 are fixedly connected to the side wall of the hub 2 at equal angles, and the blades 1 are arranged in an arc shape. After the hub 2 is sleeved and installed on the hollow shaft, the hollow shaft rotates toward the center of the blades 1. The side wall of the hub 2 is provided with a plurality of openings. During the rotation process, hydrogen is stirred and enters the interior of the hollow shaft through the openings for collection.
[0017] A connecting plate 3 is provided at both the upper and lower ends of the blade 1. The connecting plate 3 is a circular ring structure, and the connecting plate 3 is fixed to the side wall of the hub 2. A number of triangular plates are provided at equal angles on the radial edge of the connecting plate 3, and one side of the triangular plate is an arc, which fits the blade 1, that is, the triangular plate covers the upper and lower parts of the blade 1, and cooperates with the connecting plate 3 to form a semi-closed structure, which is more conducive to the enrichment and collection of hydrogen.
[0018] A threaded hole 4 is provided on the side wall of the hub 2. After the device is installed on the hollow shaft, a headless hexagon socket bolt is fitted into the threaded hole 4 and tightened to radially press against the hollow shaft to fix the hub 2.
[0019] The inner wall of the hub 2 is provided with a keyway, and the keyway is matched with a flat key 5. The flat key 5 is a common way of connecting and installing on the shaft to ensure that the hub 2 rotates with the hollow shaft.

Here, the fixing bolt 6 has a similar function to the headless hexagon socket bolt. It not only fixes the flat key 5, but also lifts the propeller hub 2 above it, further increasing the reliability of the hub 2 fixation.
