[0002] In the field of chemical production, n- and para-hydrogen catalysts are key materials for realizing the n- and para-hydrogen conversion reaction, and their packing effect directly affects the efficiency and quality of the reaction. A packing device for n- and para-hydrogen catalysts is a piece of equipment specifically designed for loading n- and para-hydrogen catalysts. It ensures that the catalyst is uniformly distributed within the reaction vessel, fully utilizing its activity and improving the efficiency of the n- and para-hydrogen conversion.

[0003] Most existing n- and para-hydrogen catalyst filling devices adopt a gravity filling structure. This type of device usually consists of a storage hopper and a feed pipe. The storage hopper is used to store the n- and para-hydrogen catalyst, and the feed pipe is connected to the reaction vessel. The catalyst is filled into the reaction vessel by gravity.

[0004] However, the above-mentioned device has the problem of uneven catalyst packing density. Under the action of gravity, the catalyst is prone to local accumulation or voids, resulting in uneven fluid distribution in the reaction bed, causing large fluctuations in the reaction conversion rate and reducing the effective utilization rate of the catalyst. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a packing device for a n- and para-hydrogen catalyst, which aims to improve the problem that uneven fluid distribution in the reaction bed caused by uneven catalyst packing density leads to large fluctuations in reaction conversion rate and reduced effective utilization of catalyst.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a filling device for a positive and negative hydrogen catalyst, comprising a filling tank, a feeding port fixedly connected to the outer wall of the filling tank, a hopper fixedly connected to the lower surface of the filling tank, a valve and a flow meter provided on the outer wall of the hopper, a reaction tank fixedly connected to the lower surface of the hopper, a support fixedly connected to the lower surface of the reaction tank, a wire mesh provided inside the reaction tank, and a vibration component provided on the lower surface of the wire mesh;

[0007] The vibration assembly includes an impact block, the upper surface of which is disposed below the wire mesh, a limit block is slidably connected to the outer wall of the impact block, a fixing plate is fixedly connected to the upper surface of the limit block, and the upper surface of the fixing plate is fixedly connected to the lower surface of the wire mesh.

[0008] Furthermore, a motor is fixedly connected to the upper surface of the filling tank, and a rotating shaft is fixedly connected to the output end of the motor. The rotating shaft is rotatably connected to the inner wall of the filling tank.

[0009] Furthermore, a crossbar is fixedly connected to the outer wall of the rotating shaft, and a stirring rod is rotatably connected to the inner wall of the crossbar.

[0010] Furthermore, a second gear is fixedly connected to the outer wall of the stirring rod, and a first gear is fixedly connected to one side of the inner wall of the filling tank. The tooth end of the first gear is meshed with the tooth end of the second gear.

[0011] Furthermore, a second motor is fixedly connected to the outer wall of the reaction vessel, and a second rotating shaft is fixedly connected to the output end of the second motor. The second rotating shaft is rotatably connected to the inner wall of the reaction vessel.

[0012] Furthermore, an eccentric wheel is fixedly connected to the output end of the rotating shaft, and a connecting rod is rotatably connected to one side of the outer wall of the eccentric wheel. One end of the connecting rod is rotatably connected to the inner wall of the impact block.

[0013] Furthermore, a connecting block is fixedly connected to the lower surface of the fixing plate, and a spring is fixedly connected to the lower surface of the connecting block.

[0014] Furthermore, a support plate is fixedly connected to one end of the spring, and the two ends of the support plate are fixedly connected to the inner wall of the reaction vessel.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, by starting the second motor, the second rotating shaft is driven to rotate, and the eccentric wheel on the second rotating shaft rotates synchronously. Then, the eccentric wheel drives the connecting rod to push the impact block to make vertical reciprocating motion, thereby realizing that the impact block continuously impacts the wire mesh. At the same time, the spring provides elastic restoring force, which makes the wire mesh form continuous and stable vibration. The contact area between the catalyst particles and the reactants after vibration and flattening is more uniform, that is, it avoids the catalyst being too dense or too sparse in some places, which affects the conversion rate of the positive and negative hydrogen catalytic reaction, thereby improving the practicality of the device.

[0017] 2. In this utility model, by starting the motor, the rotating shaft and the crossbar are driven to rotate, thereby realizing the stirring rod on the crossbar to revolve around the rotating shaft. Then, by the gear, the gear on the stirring rod is driven to rotate, so that the stirring rod rotates around its own axis at the same time. This realizes the compound motion of the stirring rod's revolution and rotation, so that the catalyst is stirred in all directions and with high intensity, thereby making the catalyst mixed evenly and improving the practicality of the device.

Detailed Implementation

[0025] 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.

[0026] Reference Figures 1-3This utility model provides an embodiment of a filling device for a secondary hydrogen catalyst, comprising a filling tank 1. The filling tank 1 is used to contain the secondary hydrogen catalyst raw material, serving to store and pre-treat the catalyst, and providing space for subsequent stirring. A motor 3 is fixedly connected to the upper surface of the filling tank 1. A rotating shaft 4 is fixedly connected to the output end of the motor 3. The rotating shaft 4 is rotatably connected to the inner wall of the filling tank 1. The motor 3 drives the rotating shaft 4 to rotate, providing a power source for stirring. A crossbar 5 is fixedly connected to the outer wall of the rotating shaft 4. A stirring rod 6 is rotatably connected to the inner wall of the crossbar 5. The crossbar 5 is used to install the stirring rod 6 and drive the stirring rod 6 to revolve around the rotating shaft 4, expanding the stirring range. A gear 8 is fixedly connected to the outer wall of the stirring rod 6. A gear 7 is fixedly connected to one side of the inner wall of the filling tank 1. The teeth of the gear 7 mesh with the teeth of the gear 8. The gear 7 and the gear 8 mesh and drive each other, driving the stirring rod 6 to rotate. The stirring rod 6 rotates on its own axis while revolving around the revolution, achieving a high-intensity three-dimensional stirring effect on the catalyst in the filling tank 1, making the catalyst evenly mixed, and effectively breaking up particle agglomeration to ensure the catalyst activity. The outer wall of the filling tank 1 is fixedly connected to the feeding port 2, which is used to add the positive and negative hydrogen catalyst raw materials into the filling tank 1 to facilitate feeding. The lower surface of the filling tank 1 is fixedly connected to the hopper 9, which is used to receive the catalyst dropped from the filling tank 1 after stirring, and plays a role in transitioning and guiding the catalyst so that the catalyst can flow smoothly to the reaction tank 12. The outer wall of the hopper 9 is equipped with a valve 10 and a flow meter 11. The flow meter 11 works with the valve 10 to adjust the feeding speed and monitor the catalyst flow rate in real time, thereby achieving precise control of the feeding amount and ensuring the stability of the catalytic reaction. The lower surface of the hopper 9 is fixedly connected to the reaction tank 12, and the lower surface of the reaction tank 12 is fixedly connected to the support 24.

[0027] Reference Figure 4 and Figure 5The reaction vessel 12 is equipped with a wire mesh 20 to support the catalyst. A vibration assembly, including an impact block 17, is located on the lower surface of the wire mesh 20. The upper surface of the impact block 17 is positioned below the wire mesh 20. A second motor 13 is fixedly connected to the outer wall of the reaction vessel 12, driving a second shaft 14 to rotate and providing power to the vibration system. The output end of the second motor 13 is fixedly connected to the second shaft 14, which is rotatably connected to the inner wall of the reaction vessel 12. An eccentric wheel 15 is fixedly connected to the output end of the second shaft 14. A connecting rod 16 is rotatably connected to one side of the outer wall of the eccentric wheel 15, with one end of the connecting rod 16 rotatably connected to the inner wall of the impact block 17. The eccentric wheel 15, in conjunction with the connecting rod 16, converts the rotational motion into linear reciprocating motion, pushing the impact block 17 to periodically impact the wire mesh 20, achieving a vibration and leveling effect. This eliminates dead zones where the catalyst accumulates, thereby increasing the catalyst's surface area. The contact area between the catalyst particles and the reactants increases the conversion rate of the catalytic reaction. A limiting block 18 is slidably connected to the outer wall of the impact block 17. The limiting block 18 is used to restrict the movement trajectory of the impact block 17, ensuring that the impact block 17 moves vertically back and forth and improving vibration stability. A fixing plate 19 is fixedly connected to the upper surface of the limiting block 18. The upper surface of the fixing plate 19 is fixedly connected to the lower surface of the wire mesh 20. A connecting block 22 is fixedly connected to the lower surface of the fixing plate 19. The fixing plate 19 is used to install the limiting block 18 and the connecting block 22, and plays a supporting and connecting role. A spring 21 is fixedly connected to the lower surface of the connecting block 22. A support plate 23 is fixedly connected to one end of the spring 21. Both ends of the support plate 23 are fixedly connected to the inner wall of the reaction vessel 12. The spring 21 and the support plate 23 form an elastic reset system, which allows the wire mesh 20 to quickly return to its original position after impact, achieving the effect of continuous and stable vibration and avoiding structural damage.

[0028] Working principle: When a catalyst is needed for the reaction of n- and bis-hydrogen, the catalyst raw material is first added to the filling tank 1 through the feeding port 2. Then, the motor 3 is started, which drives the rotating shaft 4 to rotate. The crossbar 5 on the rotating shaft 4 rotates synchronously, thereby realizing the revolution of the stirring rod 6 on the crossbar 5 around the rotating shaft 4. Then, the gear 7 on the filling tank 1 drives the gear 8 on the stirring rod 6, which is revolving around the rotating shaft 4, to rotate, so that the stirring rod 6 rotates on its own axis at the same time. This realizes the combined motion of revolution and rotation of the stirring rod 6, thereby realizing the all-round and high-intensity stirring of the catalyst in the filling tank 1. This breaks the electrostatic adsorption and agglomeration between catalyst particles, making the catalyst uniformly mixed, thus ensuring the activity of the catalyst. The stirred material flows into the hopper 9, and the feeding speed is adjusted by the valve 10. The flow meter 11 monitors the flow rate in real time to achieve precise quantitative feeding. The material then enters the reaction tank 12.

[0029] Secondly, after the material enters the reaction tank 12 and falls onto the wire mesh 20, the motor 13 is started, which drives the rotating shaft 14 to rotate. The eccentric wheel 15 on the rotating shaft 14 rotates synchronously. The eccentric wheel 15 drives the connecting rod 16 to push the impact block 17 to make vertical reciprocating motion, so that the impact block 17 continuously impacts the wire mesh 20. At the same time, the spring 21 provides elastic restoring force, which, together with the support plate 23, makes the wire mesh 20 form continuous and stable vibration. This makes the catalyst evenly distributed on the wire mesh 20, thereby eliminating dead corners of accumulation. The contact area between the catalyst particles and the reactants after vibration and flattening is more uniform, thus avoiding the catalyst being too dense or too sparse in some areas, which would affect the conversion rate of the positive and negative hydrogen catalytic reaction.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
