Cooling kettle with combined coil pipe and jacket
By combining an inner coil and a jacket structure in the cooling vessel, the inner coil directly exchanges heat with the material, and the refrigerant undergoes secondary heat exchange by filling the jacket through a spiral plate inside the jacket. This solves the problem of the outer coil not being completely wrapped in the existing cooling vessel, and achieves a more efficient cooling effect.

AI Technical Summary
The external coil of the existing cooling vessel does not completely wrap around the vessel body, leaving room for improvement in cooling efficiency.
The reactor employs a combined structure of an inner coil and an outer jacket. After the inner coil directly exchanges heat with the material, the refrigerant undergoes secondary heat exchange by filling the jacket through a spiral plate, thereby improving the encapsulation and heat exchange effect.
A better heat exchange effect is achieved through the combination of internal and external structures, requiring only one circulation pipeline, which improves the overall cooling efficiency of the cooling vessel.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a cooling vessel with a coil and jacket combination, including a vessel body 1, a jacket 2 and an inner coil 3;
[0022] A lid 4 is provided on the upper surface of the vessel body 1. A motor 6 is installed at the center of the upper surface of the lid 4 via a motor base 5. A feed inlet 21 is also provided on the upper surface of the lid 4. The output shaft of the motor 6 is connected to the top of the main shaft 7 via a coupling. The bottom of the main shaft 7 is located inside the vessel body 1 and is equipped with a stirring paddle 8. A guide sleeve 20 is provided at the center of the lower surface of the lid 4.

A discharge port 9 is provided at the bottom of the vessel body 1. A thermometer port 16, a pressure gauge port 17, and an observation port 18 are also provided on the upper surface of the lid 4. The thermometer port 16 is used to install a thermometer to monitor the temperature inside the vessel body 1. The pressure gauge port 17 is used to install a pressure gauge to monitor the pressure inside the vessel body 1. The observation port 18 is used to observe the working conditions inside the vessel body 1.
[0023] The jacket 2 is wrapped around the outside of the vessel body 1. Several support seats 19 are provided on the outer surface of the upper part of the jacket 2 to support and fix the vessel body 1. A spiral plate 10 is provided inside the jacket 2. A groove is opened on the inner surface of the spiral plate 10. A sealing strip 11 is provided in the groove on the inner side of the spiral plate 10. The sealing strip 11 is pressed onto the outer surface of the vessel body 1. A refrigerant outlet 12 is provided at the bottom of the jacket 2. A through hole 13 is opened on the upper part of the vessel body 1 and inside the jacket 2.
[0024] The inner coil 3 is installed on the inner wall of the vessel body 1 by several support rods 14. There is a gap between the surface of the inner coil 3 and the inner wall of the vessel body 1, so as to ensure that the material will not get stuck between the inner coil 3 and the inner wall of the vessel body 1. The bottom of the inner coil 3 is provided with a refrigerant inlet 15, which passes through the bottom of the vessel body 1 and the jacket 2. The upper end of the inner coil 3 is welded to the inner wall of the vessel body 1 at the through hole 13.
[0025] Processing method and operating principle: First, the vessel body 1, vessel cover 4, jacket 2, and inner coil 3 are manufactured separately. The jacket 2 contains a spiral plate 10, the inner diameter of which matches the inner diameter of the upper part of the jacket 2. The flange of the discharge port 9 at the bottom of the vessel body 1 is not welded initially. The sealing strip 11 is inserted into the groove inside the spiral plate 10. Then, the jacket 2 is fitted over the vessel body 1, allowing the discharge port 9 (without the flange) to pass through the bottom of the jacket 2. The flange is then welded to the bottom of the discharge port 9. The upper and lower parts of the jacket 2 are then welded to the connection points with the vessel body 1, completing the installation of the jacket 2. Weld the bottom of the inner coil 3 to the support rod 14, then weld the outer end of the support rod 14 to the inner wall of the vessel body 1. Pass the refrigerant inlet 15 through the jacket 2 and the bottom of the vessel body 1, and weld the refrigerant inlet 15 to the bottom of the inner coil 3. Simultaneously, weld the refrigerant inlet 15 to the jacket 2 and the vessel body 1. Next, weld the top of the inner coil 3 to the through hole 13 of the vessel body 1 to complete the installation of the inner coil 3. Finally, install the agitator 8 at the bottom of the main shaft 7, install the motor 6 on the motor seat 5 of the vessel cover 4, pass the top of the main shaft 7 through the guide sleeve 20 and connect it to the output shaft of the motor 6 through the coupling. Then lift the vessel cover 4 and place the agitator 8 and the main shaft 7 into the vessel body 1. Connect the vessel cover 4 to the top of the vessel body 1 to complete the installation. In use, the material to be cooled is fed into the vessel body 1 through the feed inlet 21. The refrigerant (such as water) enters the inner coil 3 through the refrigerant inlet 15. The refrigerant exchanges heat with the material to be cooled for the first time. Then, it passes through the through hole 13 from the upper end of the inner coil 3 and flows into the jacket 2. The refrigerant fills the jacket 2 through the spiral plate 10 inside the jacket 2 and flows to the bottom of the jacket 2. Finally, it is discharged from the refrigerant outlet 12 at the bottom of the jacket 2. The refrigerant in the jacket 2 exchanges heat with the material inside the vessel body 1 again, thereby achieving the cooling of the material. This utility model has a reasonable structure. The inner coil 3 is installed inside the vessel body 1, and the outer side of the vessel body 1 is wrapped with a jacket 2. First, the refrigerant in the inner coil 3 exchanges heat with the material to cool it down. Then, the material exchanges heat again through the outer jacket 2 to cool it down. Compared with the traditional double-layer coil structure, the encapsulation is better and the heat exchange effect is improved. At the same time, only one circulation pipeline is needed. Furthermore, the jacket 2 is equipped with a spiral plate 10 to ensure that the refrigerant entering the jacket 2 from the inner coil 3 can fill the jacket 2, thereby ensuring the cooling effect.
