[0001] This utility model relates to the field of catalyst loading technology, specifically to a catalyst loading device for hydrogenation reaction. Background Technology

[0002] Hydrogenation reactors are crucial equipment in organic chemical production processes and oil refining hydrogenation processes. They can be used not only as containers for hydrogenation reactions but also in situations where liquids and gases need to be thoroughly mixed. The catalyst loading device in a hydrogenation reactor is a key component to ensure uniform catalyst distribution, improve reaction efficiency, and extend service life.

[0003] Currently, existing catalysts for hydrogenation reactions are prone to hopper blockage during loading, preventing the catalyst from smoothly entering the hydrogenation reactor and thus affecting the process.

[0004] To address the aforementioned issues, we propose a catalyst loading device for hydrogenation reactions. Utility Model Content

[0010] Preferably, the drive shaft of the second helical blade is hollow on the side near the sealing ball.

[0011] Preferably, the protective shell is further provided with a bevel gear set, which has two meshing bevel gears. One of the bevel gears is connected to a second motor located on the outer side of the bottom of the tank, and the other bevel gear is connected to a second helical blade at the bottom of the protective shell.

[0012] Preferably, a support plate is provided at the lower end of the second motor, and the support plate is fixed to the outer side of the bottom of the tank.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through a stirring mechanism installed inside the tank, uses a first motor to drive the upper stirring rod and lower stirring blades to rotate synchronously, thereby uniformly stirring the catalyst particles inside the tank. This helps to prevent local accumulation or clumping of catalyst particles in the hopper, reducing the possibility of packing blockage in the hydrogenation reactor. It also effectively disperses and breaks up particle clumps in the catalyst, helping to prevent particle clumps from clogging the outlet or pipes, ensuring smooth feeding and extending the service life of the device. Simultaneously, through the feeding assembly at the lower end of the tank, it... The catalyst particles are conveyed and guided by the third helical blade driven by the fourth motor. Then, the catalyst particles are raised into the telescopic tube by the first helical blade driven by the third motor. The telescopic tube extends and retracts to ensure that the packing tube is positioned at the top of the hydrogenation reactor. The packing head is located at the lower end of the packing tube. Through the cross-shaped discharge holes and fan blades of the packing head, the catalyst particles are dispersed to the discharge points of the discharge holes by the rotation of the fan blades. This allows the packing head to fill the catalyst circumferentially in the hydrogenation reactor, achieving a uniform distribution of the catalyst along the circumference of the reactor. This ensures a uniform distribution of the catalyst for the hydrogenation reaction and improves the reaction efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example 1

[0024] like Figure 1-2 As shown, this embodiment discloses a catalyst loading device for hydrogenation reaction, which includes a support leg 1, a tank body 2 at the upper end of the support leg 1, a feed inlet 3 on the outer side of the top surface of the tank body 2, a stirring mechanism inside the tank body 2, and a feeding assembly corresponding to the stirring mechanism inside the tank body 2. The feeding assembly includes a discharge pipe 10 and a guide pipe 11 at the bottom of the tank body 2. A conveying pipe 9 is provided on one side of the guide pipe 11, and a telescopic pipe 5 is provided on the outer side of the top of the conveying pipe 9. A packing pipe 6 is threaded to the other end of the telescopic pipe 5, and a packing head 7 is provided at the bottom of the packing pipe 6.

[0025] In this embodiment, the stirring mechanism includes a first motor 4 located at the top center of the tank 2 and stirring rods 12 and stirring blades 13 that are integrally connected vertically. This facilitates uniform stirring of the catalyst particles inside the tank 2, helps to prevent local accumulation or agglomeration of catalyst particles in the hopper, reduces the possibility of packing blockage in the hydrogenation reactor, and can disperse and break up particle clumps in the catalyst particles in a timely manner, which helps to prevent particle clumps from blocking the outlet or pipe and ensures smooth feeding.

[0026] In this embodiment, the tank body 2 is also provided with fixed seats 8 arranged vertically on the side. The fixed seats 8 are embedded and fixedly provided with conveying pipes 9. The lower end of the conveying pipe 9 is provided with a third motor 17. The upper end of the third motor 17 is connected to a first spiral blade 16 provided inside the conveying pipe 9, which is conducive to vertical conveying of catalyst particles. Example 2

[0027] like Figure 1-5 As shown, this embodiment discloses a catalyst loading device for hydrogenation reaction, which includes a support leg 1, a tank body 2 at the upper end of the support leg 1, a feed inlet 3 on the outer side of the top surface of the tank body 2, a stirring mechanism inside the tank body 2, and a feeding assembly corresponding to the stirring mechanism inside the tank body 2. The feeding assembly includes a discharge pipe 10 and a guide pipe 11 at the bottom of the tank body 2, a conveying pipe 9 on one side of the guide pipe 11, a telescopic pipe 5 on the outer side of the top of the conveying pipe 9, a packing pipe 6 threaded to the other end of the telescopic pipe 5, a packing head 7 at the bottom of the packing pipe 6, and a stirring mechanism including a first motor 4 at the middle of the top of the tank body 2 and a stirring rod 12 and stirring blades 13 that are integrally connected vertically.

[0028] In this embodiment, a protective shell 18 is fixed inside the tank 2 at the top of the inner side of the discharge pipe 10. A second spiral blade 20 is provided at the bottom of the protective shell 18. A sealing ball 22 is movably provided at the lower end of the second spiral blade 20. A limit rod 21 is fixedly connected to the upper surface of the sealing ball 22, and an electric lifting column 29 is fixedly connected to the lower surface of the sealing ball 22. The electric lifting column 29 is fixedly provided inside the guide pipe 11, so that the electric lifting column 29 drives the sealing ball 22 to descend and rise, thereby completing the discharge and sealing. The bottom of the protective shell 18 is rectangular with four fixed columns 28 at the four corners. The bottom of the fixed columns 28 is fixedly fixed to the bottom of the inner side of the tank 2 with bolts. This is beneficial for blocking the discharge at the bottom of the tank 2 when no filling is required, under the action of the sealing ball 22, thus preventing the catalyst particles from flowing out.

[0029] In this embodiment, a bevel gear set 19 is also provided inside the protective shell 18. The bevel gear set 19 has two meshing bevel gears. One bevel gear is connected to a second motor 14 located on the outer side of the bottom of the tank body 2, and the other bevel gear is connected to a second spiral blade 20 at the bottom of the protective shell 18. A support plate 15 is provided at the lower end of the second motor 14. The support plate 15 is fixed to the outer side of the bottom of the tank body 2. When filling is required, the amount of catalyst particles discharged can be easily controlled under the action of the second spiral blade 20 to avoid too much or too little catalyst particles being discharged.

[0030] In this embodiment, the packing head 7 includes a discharge hole 25 arranged in a star shape, a conical column 26 is provided in the middle of the discharge hole 25, and a fan blade 27 is provided at the top of the conical column 26 to facilitate the uniform distribution of catalyst particles along the circumference of the reactor.

[0031] Working principle: In use, catalyst particles are first added to the tank 2 through the feed inlet 3 for storage. When it is necessary to fill the reactor, the first motor 4 drives the stirring rod 12 and stirring blade 13 inside the tank 2 to rotate synchronously, so as to uniformly stir the catalyst particles inside the tank 2. Then, the feeding assembly set at the lower end of the tank 2 drives the bevel gear set 19 set inside the protective shell 18 inside the discharge pipe 10 to rotate through the second motor 14 set on the outside of the tank 2. This drives the second spiral blade 20 set at the lower end of the protective shell 18 to rotate. When the second motor 14 is started, the electric lifting column 29 set in the guide pipe 11 drives the sealing ball 22 to rise, so that the catalyst particles flow from the bottom of the discharge pipe 10. The catalyst particles are moved into the feed pipe 11, and then the fourth motor 23 drives the third spiral blade 24 to rotate, guiding the catalyst particles into the conveying pipe 9. At the same time, the third motor 17 at the lower end of the conveying pipe 9 drives the first spiral blade 16 in the conveying pipe 9, so that the catalyst particles guided into the conveying pipe 9 follow the first spiral blade 16 to rise into the top telescopic pipe 5. The telescopic pipe 5 is set to tilt downwards, so that the catalyst particles can flow into the packing pipe 6. Through the cross-shaped discharge holes 25 and fan blades 27 of the packing head 7, the catalyst particles are dispersed by the rotation of the fan blades 27 to each discharge point of the discharge holes 25, so that the packing head 7 can be circumferentially filled with catalyst in the hydrogenation reactor, so that the catalyst is evenly distributed and filled into the hydrogenation reactor along the circumference of the reactor.
