An ultrapure ammonia refining unit usually includes multiple processing units, such as purification units, mixing units, and cooling units. Through multi-stage purification and precise control, it can produce ammonia that meets specific purity requirements.

[0003] A search revealed that Chinese patent document CN222324269U discloses an ultrapure ammonia distillation apparatus. This apparatus uses an insulation layer to isolate cold air from the outside, reducing the impact of cold air on the outlet pipe and the ammonia gas within it. This reduces the likelihood of ammonia condensing into liquid ammonia in the outlet pipe due to low external temperatures. When the external temperature is too low, a heating element raises the temperature of the sidewalls of the outlet pipe, further reducing the possibility of ammonia condensing into liquid ammonia and flowing back into the distillation column. However, the following problems remain:

[0004] When the above-mentioned ultrapure ammonia water refining device is in use, it is inconvenient to separate the insulation and heating components from the pipeline during equipment maintenance, and it is also inconvenient to disassemble and replace the faulty component separately when the heating component malfunctions. Utility Model Content

[0009] Preferably, the inner side of the heating ring is inlaid with five sets of evenly distributed temperature-conducting rings, and the temperature-conducting rings are also divided into two parts and connected to two parts of the heating ring. A heating rod is connected to one side of the temperature-conducting ring, and a socket is installed at the end of the heating rod away from the temperature-conducting ring.

[0010] Preferably, the heating ring is fixed with first connecting rings at both ends near the heat preservation ring, and the surface of the first connecting ring is provided with threaded connection.

[0024] Example 1, please refer to Figure 1-5 This utility model provides an ultrapure ammonia refining device, including a raw material tank 1, a feeding hopper 101, a feed pipe 102, a pump body 103, a distillation column 2, a gas outlet pipe 201, a discharge pipe 202, a support 203, a condenser 3, a heating ring 4, a rotating shaft 401, a first connecting ring 402, a positioning plate 403, a positioning screw 404, a heat insulation ring 5, a second connecting ring 501, a third connecting ring 502, a limiting ring 503, and a heat insulation layer. 504, temperature control box 6, connecting wire 601, socket 602, heating rod 603, temperature conducting ring 604, a distillation column 2 is installed on the side of the raw material box 1, a feeding hopper 101 is installed on the top of the raw material box 1, a feed pipe 102 is connected between the distillation column 2 and the raw material box 1, and a pump body 103 is installed on the feed pipe 102, a discharge pipe 202 is connected between the bottom of the distillation column 2 and the raw material box 1, and a support 203 is fixed at the bottom of the distillation column 2;

[0025] Specifically, such as Figure 1 and Figure 5As shown, the top of the distillation column 2 is connected to an outlet pipe 201, and the end of the outlet pipe 201 away from the distillation column 2 is connected to a condenser 3. A temperature control box 6 is installed on one side of the condenser 3. A heating ring 4 and an insulation ring 5 are distributed on the outer side of the outlet pipe 201. The heating ring 4 is divided into two parts, and a rotating shaft 401 is provided at the connection between the two parts of the heating ring 4. The two parts of the heating ring 4 are rotatably connected through the rotating shaft 401. Two sets of positioning plates 403 are fixed on the side of the heating ring 4 away from the rotating shaft 401. The two sets of positioning plates 403 are fixedly connected to the two parts of the heating ring 4 respectively, and positioning screws 404 are connected between the positioning plates 403. In this way, the two parts of the heating ring 4 can be unfolded by rotating the heating ring 4. The positioning plates 403 are fixed by fixing the positioning screws 404, so that the two parts of the heating ring 4 can be fixed. This facilitates the installation and assembly of the heating ring 4 on the outlet pipe 201, and also facilitates the disassembly of the outlet pipe 201.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, five sets of evenly distributed temperature-conducting rings 604 are embedded on the inner side of the heating ring 4. The temperature-conducting ring 604 is also divided into two parts and connected to the two parts of the heating ring 4. A heating rod 603 is connected to one side of the temperature-conducting ring 604. A socket 602 is installed at the end of the heating rod 603 away from the temperature-conducting ring 604. The temperature-conducting ring 604 can transfer the temperature of the heating rod 603 to heat the inner discharge pipe 202.

[0027] Specifically, such as Figure 2 and Figure 5 As shown, a connecting wire 601 connects the socket 602 and the temperature control box 6, which facilitates the connection between the temperature control box 6 and the heating rod 603, controls the temperature of the heating rod 603, and also facilitates the disassembly and assembly of the heating ring 4.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, the heating ring 4 is fixed with first connecting rings 402 at both ends near the heat preservation ring 5. The surface of the first connecting ring 402 is provided with threaded connection, which makes it convenient for the heating ring 4 to be connected and combined with the heat preservation ring 5 through the first connecting rings 402 at both ends.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, the insulation ring 5 is made of flexible material, and the inside of the insulation ring 5 is covered with an insulation layer 504.

[0031] Specifically, such as Figure 3 and Figure 4 As shown, a limiting ring 503 with an "L"-shaped cross-section is provided at the connection between the third connecting ring 502 and the second connecting ring 501. The limiting ring 503 is fixedly connected to the third connecting ring 502. The third connecting ring 502 is rotatably connected to the second connecting ring 501 through the limiting ring 503. In this way, rotating the third connecting ring 502 can connect it to the first connecting ring 402, thus avoiding the rotation of the insulation ring 5 and making the connection more convenient.

[0032] In this embodiment, the heating ring 4 is installed on the discharge pipe 202. The heating ring 4 is divided into two parts and can be rotated and unfolded by the pivot 401, which facilitates the installation and assembly of the heating ring 4 and the discharge pipe 202. The insulation ring 5 can wrap around the discharge pipe 202 to insulate its interior. When installing the heating ring 4, the positioning screw 404 can be rotated to fix the positioning plate 403, so that the heating ring 4 can wrap around the discharge pipe 202. Then, the third connecting ring 502 of the insulation ring 5 is rotated, and the third connecting ring 502 can be connected to the first connecting ring 402 through the threaded structure, thus completing the connection between the heating ring 4 and the insulation ring 5. By using the connecting wire 601 to connect to the socket 602, the temperature control box 6 can control the heating rod 603. Then, the heating rod 603 heats the discharge pipe 202 through the temperature conducting ring 604. 4. When a malfunction occurs or the discharge pipe 202 needs to be replaced, disconnect the connection between the connecting wire 601 and the socket 602, and then the heating ring 4 can be unfolded to complete the disassembly.
