In daily use, when it is necessary to clean the residual raw materials on the distribution plate, since the distribution plate is located deep in the tank body, it is inconvenient for the staff to clean and maintain the distribution plate. In view of this, the present utility model is specially proposed. Utility Model Content

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0019] Example 1:

[0020] Reference Figure 1 、 Figure 2 、 Figure 3, a fixed-bed hydrogenation reaction device includes a tank body 1, and also includes: a tank cover 101 detachably connected to the tank body 1; a distribution plate 103, which is connected to the tank body 1 in a lifting manner and is used to mix the gas-liquid raw materials input into the tank body 1; a sleeve 4, which is connected to the tank body 1, wherein a piston disc 401 is slidably connected to the sleeve 4, a push rod 402 is fixedly connected to the piston disc 401, and the distribution plate 103 is detachably connected to one end of the push rod 402 that passes through the tank body 1; a spring 403, which is arranged in the sleeve 4, one end of the spring 403 is fixedly connected to the piston disc 401, and the other end is fixedly connected to the inner wall of the sleeve 4; a pressing rod 405, which is fixedly connected to the tank cover 101 and abuts against the distribution plate 103.

[0021] The tank body 1 further comprises a fixing sleeve 5 which is fixedly connected to the distribution plate 103 , and one end of the push rod 402 which passes through the tank body 1 is threadedly connected to the fixing sleeve 5 .

[0022] When the distribution plate 103 needs to be cleaned, the tank cover 101 installed on the tank body 1 is first removed. At this time, the compressed spring 403 generates thrust, pushing the piston plate 401 to slide upward in the sleeve 4. When the piston plate 401 slides upward, it can push the distribution plate 103 to move upward synchronously through the push rod 402, so that it pushes the distribution plate 103 out of the tank body 1, thereby facilitating the staff to clean and maintain the distribution plate 103. At the same time, since the distribution plate 103 is disassembled and connected to the push rod 402 through the fixing sleeve 5, after the distribution plate 103 is pushed out of the tank body 1, the staff can also remove the distribution plate 103 from the push rod 402, thereby making it more convenient for the staff to clean and maintain the distribution plate 103, and when the distribution plate 103 is damaged, it can be easily disassembled and replaced.

[0023] When the cleaning and maintenance work is completed, the tank cover 101 is first installed on the tank body 1, and then the tank body 1 is closed. During the closing process, the tank cover 101 can push the distribution plate 103 downward through the pressing rod 405, so that the distribution plate 103 is pushed into the tank body 1. At the same time, when the distribution plate 103 moves downward, the push rod 402 can push the piston plate 401 to slide downward in the sleeve 4 and compress the spring 403, so that the distribution plate 103 can be installed without the help of tools or complicated operations.

[0024] Example 2:

[0025] Reference Figure 1 、 Figure 2 The fixed bed hydrogenation reaction device is basically the same as that of Example 1. Furthermore, a feeding pipe 2 connected to the tank body 1 is provided on the tank cover 101, a discharge pipe 201 is fixedly connected to the tank body 1, and a solenoid valve 202 is provided on the discharge pipe 201;

[0026] The feeding pipe 2 on the tank cover 101 is connected to the tank body 1, so that it is convenient to feed raw materials into the tank body 1;

[0027] Through the discharge pipe 201 connected to the tank body 1, when it is necessary to take out the finished raw materials processed inside the tank body 1, the solenoid valve 202 on the discharge pipe 201 is opened, and the finished raw materials can be discharged from the tank body 1 through the discharge pipe 201.

[0028] Example 3:

[0029] Reference Figure 3 The fixed-bed hydrogenation reaction device is basically the same as that of Example 1, and further includes a plurality of fixing bolts 102, and the tank cover 101 is detachably connected to the tank body 1 through the plurality of fixing bolts 102; through the setting of the fixing bolts 102, it is possible to more conveniently install or remove the tank cover 101.

[0030] Example 4:

[0031] Reference Figure 2 The fixed bed hydrogenation reaction device is basically the same as that of Example 1. Furthermore, a cooling jacket 3 for heat dissipation is fixedly connected to the outer wall of the tank body 1, and a water inlet pipe 301 and a water outlet pipe 302 are fixedly connected to the cooling jacket 3;

[0032] During use, cooling water is injected into the cooling jacket 3 through the water inlet pipe 301. After the cooling jacket 3 is filled, the excess cooling water injected into the cooling jacket 3 will flow out through the water outlet pipe 302, thereby allowing the cooling water to circulate in the cooling jacket 3 and take away the heat generated during the reaction.

[0033] Example 5:

[0034] Reference Figure 3 , a fixed bed hydrogenation reaction device is basically the same as that of Example 1, and further, a sealing sleeve 404 is provided on the tank body 1, and the sealing sleeve 404 is in contact with the outer wall of the push rod 402;

[0035] The provision of the sealing sleeve 404 increases the sealing performance of the connection between the push rod 402 and the tank body 1, thereby preventing the finished raw materials from leaking through the gap between the tank body 1 and the push rod 402, thereby reducing the waste of the finished raw materials.

[0036] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
