Abstract
Description
Technical Field
[0001] This utility model relates to the field of catalyst loading technology, and in particular to a catalyst pre-loading mechanism. Background Technology
[0002] A catalyst pre-loading mechanism is a specialized device used to load catalysts into reaction vessels (such as reactors and converters). It is an integrated device whose main function is to accurately and uniformly place the catalyst in specific locations within the reaction equipment according to predetermined methods and requirements, ensuring that the catalyst can perform optimally during the reaction. Using a catalyst pre-loading mechanism can improve loading efficiency, ensure loading quality, and reduce safety risks. Precise loading and distribution can ensure that the catalyst is fully utilized in the reactor, reducing catalyst waste. Catalyst pre-loading mechanisms are widely used in various scenarios such as petrochemicals, coal chemicals, oil chemicals, environmental protection, clean energy, and fine chemicals.
[0003] Existing catalyst prefabrication and filling machines typically consist of a storage section, a conveying section, a distribution section, and a filling section to achieve their effect. The silo or storage tank is the main component for storing the catalyst. The distributor has various shapes and structures, such as disc type and multi-tube type. The filling head is directly connected to the filling port of the reaction vessel.
[0004] However, the existing loading mechanism does not distribute the catalyst evenly. Uneven catalyst distribution will lead to uneven contact between the material and the catalyst during the reaction process. Different catalyst loading in different areas will cause the reaction rate to vary in different areas, affecting the reaction efficiency. Utility Model Content

A second fixing block is fixedly connected to the inner wall of the valve plate. The inner wall of the second fixing block is fixedly connected to the outer wall of the first rotating rod. A second fixing disc is rotatably connected to the outer wall of the first rotating rod.
[0008] Furthermore, the diversion assembly includes a first connecting pipe, the upper surface of which is fixedly connected to the lower surface of the first diversion pipe, a third connecting pipe fixedly connected to the lower surface of the first diversion pipe, a second connecting pipe fixedly connected to the lower surface of the first diversion pipe, and a first fixing plate fixedly connected to the outer wall of the second connecting pipe.

[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the flow rate of the catalyst can be precisely adjusted by the action of the handwheel and the valve plate, which can improve the uniformity of catalyst distribution. Furthermore, the catalyst can be loaded from different positions through multiple distribution connecting pipes, which helps to achieve a more uniform distribution.

A third connecting pipe 25 is fixedly connected to the lower surface of the first flow divider 9, and a second connecting pipe 24 is fixedly connected to the lower surface of the first flow divider 9. The first flow divider 9 allows the catalyst to be loaded simultaneously from different positions. A first fixing plate 11 is fixedly connected to the outer wall of the second connecting pipe 24. A support grid 12 is provided below the first fixing plate 11. The support grid 12 is used to place the catalyst and prevent catalyst particles from falling off, while allowing the reaction fluid to pass through.

[0026] Reference Figures 1-2 The upper surface of the reaction vessel 3 is fixedly connected to the feed pipe 2, the lower surface of the reaction vessel 3 is fixedly connected to the base plate 7, the lower surface of the base plate 7 is fixedly connected to the support leg 8, the support leg 8 is used to support the reaction vessel 3, the outer wall of the support leg 8 is fixedly connected to the first connecting column 6, the upper surface of the vibration motor 14 is fixedly connected to the lower surface of the base plate 7, the lower surface of the base plate 7 is fixedly connected to the discharge pipe 13, the catalyst after reaction flows out from the discharge pipe 13, the reaction vessel 3 is provided with a box door 4, the outer wall of the box door 4 is fixedly connected to the handle 5, pulling the handle 5 can open the box door 4, thereby cleaning the unreacted impurities on the support grid 12, the outer wall of the first diversion pipe 9 is fixedly connected to the lower surface of the feed pipe 2, and the outer wall of the first fixed plate 11 is fixedly connected to the inner wall of the reaction vessel 3.
[0027] Working principle: When the catalyst needs to be loaded, different types of catalysts are first poured into the feed hopper 1. Then, the handwheel 15 is turned to drive the first rotating rod 16 to rotate, causing the valve plate 20 to flip and the catalyst to fall into the second diversion pipe 22. When the catalyst flows into the first diversion pipe 9, it can be discharged through different pipes such as the third connecting pipe 25, the first connecting pipe 10, and the second connecting pipe 24. When the catalyst falls above the support grid 12, the catalyst reacts. At the same time, the vibration motor 14 starts to work, driving the reaction vessel 3 to vibrate, so that the catalyst above the support grid 12 flows better and reduces the accumulation of catalyst. The reacted material flows out from below the support grid 12 and then flows out from the discharge pipe 13. When there is too much catalyst in the reaction vessel 3, the handwheel 15 is turned to close the valve plate 20, thereby stopping the catalyst discharge.
