[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. An internal coil reaction vessel, on the other hand, has an internal coil inside. The heat exchange medium enters the internal coil to exchange heat with the materials inside the vessel.

[0003] In existing internal coil reactors, the outer side of the coil support is generally connected to the inner wall of the reactor, and the bottom is connected to the bottom of the reactor.

[0023] The coil support includes an upper ring plate 8, a lower ring plate 9, a reinforcing plate 10, and uprights 11. The lower ring plate 9 is provided on the lower surface of the upper ring plate 8 through several radially distributed reinforcing plates 10. The outer ends of the upper ring plate 8, the lower ring plate 9, and the reinforcing plates 10 are all connected to the inner wall of the vessel body 1. Several uprights 11 are vertically connected to the inner sides of the upper ring plate 8 and the lower ring plate 9. The upper ring plate 8 is connected to the top of the uprights 11. Several through grooves 17 are provided on both the upper ring plate 8 and the lower ring plate 9 to prevent material from accumulating on the upper ring plate 8 or the lower ring plate 9.

[0024] The outer edge of the inner coil 2 is connected to the inner side of each upright 11. The inner coil 2 is provided with extension sections 12 at both ends and is connected to two flange joints 13 through the two extension sections 12 respectively.

[0025] The agitator includes a main shaft 14, rod-type agitators 15, and U-shaped agitators 16. The top end of the main shaft 14 is connected to the output shaft of the motor 4 via a coupling, and the bottom end of the main shaft 14 is rotatably connected to the bearing seat 7. The main shaft 14 is equipped with several rod-type agitators 15, and the lower part of the main shaft 14 is connected to the U-shaped agitators 16. The middle positions of the rod-type agitators 15 and the U-shaped agitators 16 are fastened to the main shaft 14 via sleeves 18 and bolts to realize the connection and disassembly of the rod-type agitators 15 and the U-shaped agitators 16 from the main shaft 14. The two ends of the U-shaped agitators 16 are bent upward and rotatably disposed between the upright rod 11 and the inner wall of the vessel body 1.

[0026] Installation method and operating principle: First, assemble the coil support. Weld the upper ring plate 8 and the lower ring plate 9 together with several reinforcing plates 10. Weld multiple uprights 11 vertically to the inner sides of the upper ring plate 8 and the lower ring plate 9 respectively. Then, weld the outer edge of the inner coil 2 to each upright 11, and extend both ends of the inner coil 2 upwards. Secure the rod-type agitator 15 to the main shaft 14 with sleeves 18 and bolts. Connect the top of the main shaft 14 to the output shaft of the motor 4 mounted on the vessel cover 3 through a coupling. Next, place the upper ring plate 8, the lower ring plate 9, and the inner coil 2 around the main shaft 14. Finally, secure the U-shaped agitator 16 to the bottom of the main shaft 14 with sleeves 18 and bolts. The vessel lid 3 is hoisted using a steel wire rope, and another set of steel wire ropes passes through the manhole 21 to suspend the coil support. The agitator is then placed inside the vessel body 1, and the coil support is simultaneously placed inside the vessel body 1, allowing the bottom of the main shaft 14 to connect with the shaft seat 7. The inner upper ring plate 8, lower ring plate 9, and reinforcing plate 10 are manually welded to the inner wall of the vessel body 1, requiring continuous suspension of the coil support using hoisting equipment. After welding, the operator climbs out through the manhole 21, completing the installation. During operation, heat exchange media such as hot gas, hot oil, and cold water enter the inner coil 2 through one flange joint 13 and exit through the other flange joint 13, thus achieving heat exchange with the material. The motor 4 drives the main shaft 14 to rotate, thereby driving the rod-type agitator 15 and the U-shaped agitator 16 to rotate to agitate the material. The bent portions at both ends of the U-shaped agitator 16 rotate between the upright 11 and the inner wall of the vessel body 1. This utility model has a reasonable structure. The inner coil 2 is connected to the upright rod 11, and the upright rod 11 is connected to the inner edge of the upper ring plate 8 and the lower ring plate 9. The upper ring plate 8 and the lower ring plate 9 are connected by the reinforcing plate 10 and are both connected to the inner wall of the vessel body 1. A U-shaped stirring paddle 16 is provided at the bottom of the main shaft 14. The two ends of the U-shaped stirring paddle 16 are bent upward and rotated between the upright rod 11 and the inner wall of the vessel body 1. It is also located below the lower ring plate 9. The U-shaped stirring paddle 16 can stir the area inside and outside the vessel body 1, which greatly improves the stirring effect of the material inside the vessel body 1.
