[0026] The following clearly and completely describes the technical solutions of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0027] As Figure 1 shown, a thermocouple tube 20 is provided in the reactor inlet 10 of the fixed-bed reactor, and the thermocouple tube 20 is used to place a thermocouple. When filling the catalyst into the fixed-bed reactor, the impact of the catalyst on the thermocouple tube 20 may cause a change in the position of the thermocouple tube 20.

[0028] As Figure 2 shown, an embodiment of the present application provides a loading device 100 for a catalyst of a fixed-bed reactor. The loading device 100 includes: a feed hopper 1, a first support assembly 2, a second support assembly 3, a first locking assembly 4, and a second locking assembly 5.

[0029] As Figure 3 and Figure 4 shown, the feed hopper 1 is in an inverted conical shape, with the top being the hopper inlet 11 and the bottom being the hopper outlet 12. The diameter of the hopper inlet 11 is larger than the diameter of the hopper outlet 12. The bottom end of the feed hopper 1 can enter the reactor inlet 10, and the thermocouple tube 20 of the fixed-bed reactor can enter the feed hopper 1 from the hopper outlet 12.

[0030] The first support assembly 2 is connected to the feed hopper 1. For example, the first support assembly 2 is connected to the outer wall of the feed hopper 1. The second support assembly 3 is connected to the feed hopper 1. For example, the second support assembly 3 is connected to the inner wall of the feed hopper 1.

[0031] The first locking assembly 4 is connected to the first support assembly 2. For example, the first locking assembly 4 is provided at the bottom end of the first support assembly 2, and the first locking assembly 4 can be connected to the reactor inlet 10.

[0032] The second locking assembly 5 is connected to the second support assembly 3. For example, the second locking assembly 5 is provided at the bottom end of the second support assembly 3, and the second locking assembly 5 can be connected to the thermocouple tube 20. The first locking assembly 4 is connected to the reactor inlet 10, and the second locking assembly 5 is connected to the thermocouple tube 20 so that the relative position between the thermocouple tube 20 and the reactor inlet 10 does not change.

[0033] The loading device 100 of this embodiment is provided with two locking components. The first locking component 4 can fix the relative position of the reactor inlet 10 and the feed hopper 1, and the second locking component 5 can fix the relative position of the thermocouple tube 20 and the feed hopper 1. The bottom end of the feed hopper 1 is inserted into the reactor inlet 10, and the thermocouple tube 20 enters the feed hopper 1 from the hopper outlet 12. The catalyst can enter the reactor inlet 10 through the gap between the feed hopper 1 and the thermocouple tube 20. When the catalyst impacts the thermocouple tube 20, the relative position between the thermocouple tube 20 and the reactor inlet 10 will not change, reducing the difficulty of catalyst loading.

[0034] As Figure 5 shown, in some embodiments, the first support component 2 includes a plurality of first support rods 21, and the tops of the plurality of first support rods 21 are all connected to the outer wall of the feed hopper 1. For example, the number of the first support rods 21 is three, and the three first support rods 21 are circumferentially and evenly distributed around the axis of the feed hopper 1. The first locking component 4 is connected to at least one first support rod 21.

[0035] In some embodiments, the length of the first support rod 21 is 100 - 180 mm. For example, the length of the first support rod 21 is 140 mm, which is convenient for the first locking component 4 to connect to the reactor inlet 10. The material of the first support rod 21 is stainless steel, and the thickness is 0.5 mm.

[0036] In some embodiments, the second support component 3 includes a plurality of second support rods 31, and the tops of the plurality of second support rods 31 are all connected to the outer wall of the feed hopper. Optionally, the tops of the second support rods 31 can also be connected to the bottom surface of the feed hopper. For example, the number of the second support rods 31 is three, and the three second support rods 31 are circumferentially and evenly distributed around the axis of the feed hopper 1. The second locking component 5 is connected to at least one second support rod 31.

[0037] In some embodiments, the length of the second support rod 31 is 120 - 160 mm. For example, the length of the second support rod 31 is 150 mm, which is convenient for the second locking component 5 to connect to the thermocouple tube 20. The material of the second support rod 31 is stainless steel, and the thickness is 0.5 mm.

[0038] In some embodiments, the first locking component 4 includes a first clamp, and the first clamp is located at the bottom end of the first locking component 4. The diameter of the first clamp is adjustable, and the first clamp can be a existing clamp. Optionally, the first clamp is bonded to one first support rod 21. The first clamp bypasses from the outside of each first support rod 21. When the diameter of the first clamp shrinks, the bottom end of the first support rod 21 contracts towards the axis of the feed hopper 1. Adjust the diameter of the first clamp according to the outer diameter of the reactor inlet 10 so that the first clamp can be sleeved on the outside of the reactor inlet 10. There is a small gap between the first clamp and the reactor inlet 10 to facilitate sleeving the first clamp on the reactor inlet 10.

[0039] In some embodiments, the diameter adjustment range of the first clamp is 60 - 210 mm, and the outer diameter of the reactor inlet is 100 - 130 mm. The diameter of the first clamp is adjusted according to the outer diameter of the reactor inlet 10.

[0040] In some embodiments, the second locking assembly 5 includes a second clamp, and the second clamp is located at the bottom end of the second support rod 31. The diameter of the second clamp is adjustable, and an existing clamp can be selected for the second clamp. Optionally, the second clamp is bonded to one second support rod 31 and bypasses the outside of each second support rod 31. When the diameter of the second clamp shrinks, the bottom end of the second support rod 31 contracts towards the axis of the feed hopper 1. The diameter of the second clamp is adjusted according to the outer diameter of the thermocouple tube 20 so that the second clamp can be sleeved outside the thermocouple tube 20. There is a slight gap between the second clamp and the thermocouple tube 20 to facilitate sleeving the second clamp onto the thermocouple tube 20.

[0041] In some embodiments, the diameter adjustment range of the telescopic second clamp is 6 - 25 mm, and the outer diameter of the thermocouple tube 20 is 10 - 18 mm. The diameter of the second clamp is adjusted according to the outer diameter of the thermocouple tube 20.

[0042] In some embodiments, the diameter of the hopper inlet 11 of the feed hopper 1 is 160 - 250 mm, and the diameter of the hopper outlet 12 is 60 - 100 mm. For example, the inner diameter of the reactor inlet 10 is 100 mm, the diameter of the hopper inlet 11 is 200 mm, and the diameter of the hopper outlet 12 is 80 mm, which facilitates inserting the bottom end of the feed hopper 1 into the reactor inlet 10.

Specific examples are used herein to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the technical solution and its core idea of the present application.
