Description

Technical Field

[0001] This utility model relates to the field of petrochemical catalyst technology, specifically to a petrochemical catalyst disperser. Background Technology

[0002] Petrochemical catalysts are catalysts used in the chemical processing of petrochemical products. There are many types of these catalysts, which, according to their catalytic function, mainly include oxidation catalysts, hydrogenation catalysts, dehydrogenation catalysts, hydroformylation catalysts, polymerization catalysts, hydration catalysts, dehydration catalysts, alkylation catalysts, isomerization catalysts, and disproportionation catalysts. The first five types are used in larger quantities. Petrochemical catalysts can improve reaction efficiency, reduce energy consumption, and optimize product distribution.

[0003] Currently, during the process of petrochemical catalysts entering the reactor to participate in the reaction, a large amount of solid catalyst tends to deposit or accumulate at the bottom of the reactor. The horizontal stirring rods distributed in the container are insufficient to effectively lift and agitate the catalyst at the bottom, making it difficult for the catalyst to disperse effectively upwards, which greatly affects the chemical reaction effect. Utility Model Content

[0004] The purpose of this invention is to provide a petrochemical catalyst disperser. By incorporating a fixed column, support arm, tilting plates, baffles, and movable blocks, and with the cooperation of push-pull rods and drive components, when the petrochemical catalyst settles or accumulates at the bottom of the reactor, the push-pull rods drive the movable blocks to move up and down. This movable blocks, through connecting rods and support arms, cause multiple sets of tilting plates and baffles to tilt up and down. Simultaneously, the connecting shaft, through the fixed column, drives multiple sets of tilting plates and baffles to rotate. Under the combined movement of this structure, the settled and accumulated petrochemical catalyst can be dispersed to various parts of the raw material, effectively preventing a large amount of catalyst from settling and accumulating at the bottom, greatly ensuring the mixing reaction effect, and thus solving the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a petrochemical catalyst disperser, comprising:

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1-4 A petrochemical catalyst disperser shown includes:

[0026] Reactor 1, with a drive motor 2 at the top of reactor 1, the output end of drive motor 2 connected to a connecting shaft 3, the bottom end of connecting shaft 3 extending into reactor 1 and fitted with a fixing column 5;

[0027] The bottom of the fixed column 5 is provided with a sliding cavity 11, and the bottom of the fixed column 5 is provided with multiple support arms 6 in a circular array through a rotating shaft. Each of the multiple support arms 6 is fixed with a flipping plate 7 at one end relative to the fixed column 5. The sliding cavity 11 is slidably connected with a movable block 10. The movable block 10 and the multiple support arms 6 are rotatably connected with a connecting rod 9 through a rotating shaft. The side wall of the fixed column 5 is provided with multiple slides 12 that are adapted to the connecting rods 9.

[0028] A baffle 8 is fixed in the middle of the top side of the flipping plate 7.

[0029] The fixed column 5 has a cavity 14 located above the sliding cavity 11. A push-pull rod 17 is connected through the cavity 14 and the sliding cavity 11. The bottom end of the push-pull rod 17 is fixedly connected to the movable block 10, and the top end of the push-pull rod 17 is connected to a drive assembly.

[0030] The drive assembly includes a threaded rod 15 rotatably connected to the top of the cavity 14 via a bearing. A built-in motor 16 is embedded in the top of the fixed column 5 near the cavity 14. The output end of the built-in motor 16 extends into the cavity 14 and is connected to the threaded rod 15. The top of the push-pull rod 17 is provided with a threaded channel 18, and the threaded rod 15 is screwed into the threaded channel 18.

[0031] When the petrochemical catalyst settles or accumulates at the bottom of the reactor 1, the built-in motor 16 can be started, which drives the threaded rod 15 to rotate in both directions. With the cooperation of the threaded channel 18, the limiting post 19, and the limiting groove 20, the push-pull rod 17 can be driven to move up and down in a straight line. Then, the push-pull rod 17 can drive the movable block 10 to move in the sliding cavity 11, so that the movable block 10 drives multiple sets of support arms 6 to rotate through the connecting rod 9. After that, the support arms 6 can drive multiple sets of tilting plates 7 and baffles 8 to tilt up and down.

[0032] Simultaneously, the drive motor 2 can be started, causing the drive motor 2 to drive the fixed column 5 to rotate. Then, the fixed column 5 drives multiple sets of turning plates 7 and baffles 8 to rotate through the support arm 6. Under the joint movement of this structure, the settled and agglomerated petrochemical catalyst can be turned over and dispersed to various parts of the raw materials, effectively preventing a large amount of catalyst from settling and agglomerating at the bottom, and greatly ensuring the mixing reaction effect.

[0033] The top of the push-pull rod 17 is symmetrically provided with limiting posts 19 on both sides, and the inside of the cavity 14 is provided with limiting grooves 20 that match the limiting posts 19. Based on this, by setting the limiting posts 19 and limiting grooves 20, the push-pull rod 17 can drive the limiting posts 19 to slide along the limiting grooves 20, thereby limiting and guiding the push-pull rod 17 and greatly ensuring the stability of the push-pull rod 17 when it moves up and down.

[0034] A sealing ring 13 is provided at the top of the inner cavity 11, and the sealing ring 13 is sleeved on the outside of the push-pull rod 17. Based on this, the sealing ring 13 can play a role in sealing and preventing leakage.

[0035] The top of the fixed column 5 is provided with a fixed seat 4, and the top of the fixed seat 4 is provided with a slot 21. The bottom end of the connecting shaft 3 can be inserted into the slot 21. Both sides of the fixed seat 4 are connected with fastening bolts 22 by threaded engagement. Both sides of the bottom end of the connecting shaft 3 are provided with positioning holes 23 that match the fastening bolts 22.

[0036] By inserting the connecting shaft 3 into the slot 21 on the fixed base 4 and screwing the fastening bolts 22 on both sides of the fixed base 4, the ends of the fastening bolts 22 are tightened into the positioning holes 23, thereby fixing the fixed base 4 onto the connecting shaft 3 for installing the fixed column 5. Conversely, the fixed column 5 can be removed, which facilitates disassembly and maintenance and greatly improves the effectiveness of the device.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
