The heat insulation and protection component is arranged on the outer surface of the reaction tank 101, and the fixed installation component is arranged at the top end of the heat insulation and protection component. When the reaction kettle body 100 is heated during processing and production, when the outer surface of the reaction kettle body 100 is heated, the heat insulation and protection mechanism provides heat insulation and protection for the outer surface of the reaction kettle body 100. It is not easy for operators to encounter danger when touching the surface of the reaction tank 101, ensuring safe operation and improving the protection effect and safety of the reaction kettle body 100 during processing and production.

[0025] In order to facilitate the heat insulation and protection of the outer surface of the reaction kettle body 100 through the heat insulation and protection component, strengthen safe operation during heating and prevent danger from occurring easily. In this embodiment, preferably, the heat insulation and protection component includes a protection cylinder 1011 arranged on the outer surface of the reaction tank 101. A connection hole 1012 is opened at the top edge of the protection cylinder 1011. When the protection cylinder 1011 is used for heat insulation and protection, when the inside of the protection cylinder 1011 is heated, it is discharged through the connection hole 1012 and the bottom end of the protection cylinder 1011, facilitating heat insulation and protection as well as heat treatment.

[0026] In order to facilitate the re - fixed installation of the protection cylinder 1011 after being sleeved and installed through the fixed installation component, in this embodiment, preferably, the fixed installation component includes a fixed installation ring 1015 integrally formed on the inner surface of the top end of the protection cylinder 1011. After the protection cylinder 1011 is sleeved on the outer surface of the reaction tank 101, the fixed installation ring 1015 closes on the end surface of the reaction tank 101. A fixed bolt 1013 is rotatably connected inside the fixed installation ring 1015. An internal thread hole 1014 is opened at the top edge of the reaction tank 101. The end of the fixed bolt 1013 matches the internal structure of the internal thread hole 1014.

By rotating the fixed bolt 1013 again and inserting it into the internal thread hole 1014, the fixed installation ring 1015 and the protection cylinder 1011 are fixedly installed, facilitating the fixed installation of heat insulation and protection.

[0027] Reinforcement and sealing mechanism, and this reinforcement and sealing mechanism includes a rotary reinforcement and sealing component and an elastic extrusion component. The rotary reinforcement and sealing component is arranged at the end of the feed pipe 105, and the elastic extrusion component is arranged at the bottom edge inside the rotary reinforcement and sealing component. When the reaction kettle body 100 is in use, the reinforcement and sealing mechanism strengthens the seal between the end of the feed pipe 105 and the rubber sleeve 1053. During operation, it is not easy to leak, improving the sealing effect and the convenience of sealing installation of the feed pipe 105 and the rubber sleeve 1053 in the reaction kettle body 100 during processing and production.

[0028] In order to facilitate the strengthening and fixing of the seal by rotating the reinforcement seal assembly and prevent gas leakage easily when heated, in this embodiment, preferably, the rotating reinforcement seal assembly includes a rubber sleeve 1053 sleeved on the top end of the feed pipe 105. An internally threaded fixing cover 1051 is provided on the outer surface of the rubber sleeve 1053 to facilitate the extrusion and fixed installation by rotating the internally threaded fixing cover 1051. An extrusion fixing ring 1052 is integrally formed at the inner top end of the internally threaded fixing cover 1051. An externally threaded ring 1054 is provided at the bottom end of the outer surface of the feed pipe 105. The outer surface structure of the rubber sleeve 1053 matches that of the feed pipe 105, and the extrusion fixing ring 1052 is correspondingly arranged with the end of the feed pipe 105. The internally threaded fixing cover 1051 can be rotated through the externally threaded ring 1054 until the internally threaded fixing cover 1051 rotates to a certain position, and then the rubber sleeve 1053 is strengthened and sealed by the extrusion of the extrusion fixing ring 1052 on its surface.

[0029] In order to facilitate the reinforcement installation after the internally threaded fixing cover 1051 rotates to a certain extent through the elastic extrusion assembly, in this embodiment, preferably, the elastic extrusion assembly includes an elastic extrusion protrusion 1056 provided at the bottom edge of the inner surface of the internally threaded fixing cover 1051. An extrusion groove 1055 is formed at the bottom edge of the outer surface of the feed pipe 105. When the internally threaded fixing cover 1051 is rotated to the bottommost position, the internally threaded fixing cover 1051 is strengthened and installed by the elastic engagement of the elastic extrusion protrusion 1056 in the extrusion groove 1055, which is easy to strengthen the seal.

[0030] The working principle and usage process of the present utility model: For this kind of ammonia-to-urea deammoniation device, during use, the reaction kettle main body 100 can be stably placed at the processing position. Before use, the protective cylinder 1011 can be sleeved on the outer surface of the reaction tank 101, the fixed installation ring 1015 is closed on the outer surface of the top end of the reaction tank 101, and the fixing bolt 1013 is rotated and embedded into the internal threaded hole 1014 to fix and install the protective cylinder 1011, which is convenient for heat insulation protection of the outer surfaces of the reaction tank 101 and the heating ring 104 through the protective cylinder 1011. When the outer surface of the reaction kettle main body 100 receives a large amount of heat during long-term use, it is heat-insulated and protected by the protective cylinder 1011, and it is not easy for the operator to be in danger when touching the surface of the reaction tank 101, ensuring safe operation and improving the protection effect and safety of the reaction kettle main body 100 during processing and production;

[0031] Then, before the reactor main body 100 undergoes a processing operation, the rubber sleeve 1053 is sleeved and installed on the outer surface of the feed pipe 105. The internal-thread fixing cover 1051 is closed on the outer surface of the rubber sleeve 1053 and rotated on the outer surface of the external-thread ring 1054 until, when the internal-thread fixing cover 1051 is rotated to a certain extent, the elastic extrusion protrusion 1056 is elastically pressed tightly inside the extrusion groove 1055 to reinforce and install the internal-thread fixing cover 1051. After the internal-thread fixing cover 1051 is rotationally fixed, it drives the extrusion fixing ring 1052 to press on the upper surface of the rubber sleeve 1053, and the inner surface of the rubber sleeve 1053 is extruded to contact the end surface of the feed pipe 105, facilitating the reinforcement, sealing, and closing of the rubber sleeve 1053. Moreover, the existing sealing structure for closing is simpler and more convenient, saving costs and being more sealed. During heat production in processing, it is not easy for gas to leak between the feed pipe 105 and the rubber sleeve 1053, improving the sealing effect and the convenience of sealing installation between the feed pipe 105 and the rubber sleeve 1053 during the processing and production of the reactor main body 100.
