Abstract
Description
Technical Field
[0001] This utility model relates to the field of reactor technology, specifically a fixed-bed reactor. Background Technology
[0002] Fixed-bed reactors are a type of reactor widely used in industry and scientific research. They are mainly used for multiphase catalytic reaction processes between gas-solid or liquid-solid phases. Gas or liquid reactants flow in from one end of the reaction vessel, pass through the gaps between particles and flow through the stationary solid catalyst bed, where a chemical reaction occurs on the catalyst surface.
[0003] In traditional fixed-bed catalyst reactors, the top or bottom end caps are usually removed to load or unload the catalyst packing. When new catalyst needs to be loaded, the operator opens the top end cap of the fixed-bed reactor and then manually puts the catalyst into the reactor one by one. When old catalyst needs to be unloaded, the bottom end cap of the fixed-bed reactor needs to be opened, and the used catalyst is removed haphazardly by manpower.
[0004] However, because the catalyst particles are small and easily dispersed, they are easily lost during loading and unloading, which not only increases costs but may also pollute the environment. Since the whole process relies on manual operation, the efficiency is relatively low, especially when dealing with large quantities of catalysts, which involves a huge workload, is time-consuming, and affects processing efficiency. Optimization and improvement are needed. Utility Model Content
[0005] The purpose of this invention is to provide a fixed-bed reactor to solve the problem of inconvenient packing materials in fixed-bed reactors mentioned in the background art.

[0007] A packing adjustment assembly is located on the outside of the feed pipe. The packing adjustment assembly includes a sliding adjustment frame, a mounting plate at the top of the sliding adjustment frame, a feed hopper inside the mounting plate, and a plug at the bottom of the mounting plate. The packing adjustment assembly is used for packing and plugging the feed pipe.
[0008] The unloading adjustment assembly is located on the outside of the discharge pipe and includes a clamping part one, a clamping part two at one end of the clamping part one, and a flexible receiving pipe at the bottom end of the clamping part two. The unloading adjustment assembly is used to guide the unloading of the discharge pipe.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0026] like Figure 1 - Figure 4 As shown, this application provides a fixed-bed reactor, including: a reactor body 1, a connecting pipe 2 connected to the outside of the reactor body 1, a feed pipe 3 installed at the top of the reactor body 1, and a discharge pipe 4 installed at the bottom of the reactor body 1.
[0027] A packing adjustment assembly is provided on the outside of the feed pipe 3, and the packing adjustment assembly includes a sliding adjustment frame 5. The top of the sliding adjustment frame 5 is provided with a mounting plate 9, and the inside of the mounting plate 9 is provided with a feed hopper 10. The bottom of the mounting plate 9 is provided with a plug 12. The packing adjustment assembly is used for packing and plugging the feed pipe 3.
[0028] Specifically, such as Figure 3 As shown, the sliding adjustment frame 5 is fixedly installed on the top of the reactor body 1, and the outer side of the sliding adjustment frame 5 is connected to the limiting magnetic suction plate 6. The limiting magnetic suction plate 6 is set on both sides and one end of the sliding adjustment frame 5, which can position the sliding frame 7 at different positions.
[0029] Specifically, such as Figure 3 As shown, a sliding frame 7 is slidably connected to the top of the sliding adjustment frame 5, and a positioning block 8 is installed on the outside of the sliding frame 7. The positioning block 8 is made of iron and can be attracted and positioned by the limiting magnetic plate 6.
[0030] Specifically, such as Figure 3As shown, a mounting plate 9 is installed at the top of the sliding frame 7, and a handle 13 is fixedly installed at the top of the mounting plate 9, which can facilitate the sliding adjustment of the mounting plate 9.
[0031] Specifically, such as Figure 3 As shown, a feed hopper 10 is fixedly connected inside the mounting top plate 9, and an elastic rod 11 is connected to the bottom inner side of the mounting top plate 9. A plug 12 is connected to the bottom of the elastic rod 11. The plug 12 has the same diameter as the inlet of the feed pipe 3 and can cover and seal the top.
[0032] The discharge pipe 4 is provided with a discharge adjustment component, which includes a clamp 14, a clamp 27 at one end of the clamp 14, and a flexible receiving pipe 20 at the bottom end of the clamp 27. The discharge adjustment component is used to guide the discharge of material from the discharge pipe 4.
[0033] Specifically, such as Figure 4 As shown, clamp 14 is located on the outside of discharge pipe 4, and both ends of clamp 14 are connected to connecting blocks 15. The inner side of connecting block 15 is connected to telescopic plate 16. The telescopic plate 16 can be stored inside the connecting block 15 by the compression of the spring, and then pass through the inner side of the clip frame 18 for snap-fit positioning.
[0034] Specifically, such as Figure 4 As shown, an elastic guide rod 19 is connected to the inner side of the connecting block 15, and a retaining frame 18 is connected to the inner side of the elastic guide rod 19. The distance between the connecting block 15 and the retaining frame 18 is controlled by the connection of the elastic guide rod 19, which facilitates the snapping of the telescopic plate 16.
[0035] Specifically, such as Figure 4 As shown, the connecting block 15 and the elastic guide rod 19 are fixedly connected, and the elastic guide rod 19 and the frame 18 are slidably connected. The elastic connection of the elastic guide rod 19 can pre-position the distance between the clamping part 14 and the clamping part 17.
[0036] In this embodiment: by setting a replaceable feed hopper 10 and plug 12 at the feed pipe 3, the sealing and feeding modes can be changed by sliding movement, which can avoid opening the top cover before filling with material. The bottom end is connected to the flexible receiving pipe 20 by clamp 14 and clamp 27. Clamp 14 and clamp 27 can be easily disassembled and assembled outside the discharge pipe 4, and can be used for guided unloading.
[0037] Specifically, during the material filling process, the top plate 9 is connected to the sliding frame 7 and slides on the top of the sliding adjustment frame 5. Then, the feed hopper 10 is aligned with the feed pipe 3, and material transfer is carried out. After the transfer is completed, the top of the feed pipe 3 is sealed by the plug 12. The elastic rod 11 can increase the tightness of the plug 12. Then, the reactor body 1 is put into operation. When the internal material is recycled after use, the flexible receiving pipe 20 is connected by the clamping part 14 and the clamping part 27. At this time, the telescopic plate 16 is squeezed and stuck inside the clamping frame 18, allowing the bottom end of the discharge pipe 4 to extend through the flexible receiving pipe 20, avoiding material dispersion and facilitating recycling.
