Description

Technical Field

[0001] This utility model relates to the field of heating kettles, specifically to an internal heating kettle. Background Technology

[0002] Resin is required in the production process of cathodic electrophoretic coatings. Resin has high viscosity, and the currently widely used heating method is a jacketed heating autoclave. However, this method has certain limitations for resin, resulting in less than ideal heating effects, which in turn affects the efficiency and quality of the entire production process. Summary of the Invention

[0003] This utility model aims to provide an internally heated vessel, the specific solution of which is as follows:

[0004] An internal heating vessel includes a vessel body, with annular coil frames respectively disposed on the upper and lower parts of the vessel body. Heating coils are mounted on the annular coil frames, each heating coil comprising a U-shaped coil and a retaining ring. The retaining ring is welded to the annular coil frame or fixed by bolts. Each heating coil includes an inlet pipe, an outlet pipe, and several repeatedly arranged coil units. Each coil unit includes a U-shaped coil and a vertical straight pipe, and the U-shaped coils of two adjacent coil units have opposite directions.

[0005] The U-shaped coil and the vertical straight pipe are welded. Welding can be used when the heating vessel requires almost no disassembly.

[0006] The U-shaped coil has internal threads at both ends, and the vertical straight pipe has external threads at both ends. The U-shaped coil and the vertical straight pipe are connected by threads. If the heating vessel needs to be disassembled, a threaded connection can be used.

[0007] The vessel body is equipped with a feeding port, and a baffle is installed inside the vessel body. The feeding port and the baffle are configured in conjunction. The position of the baffle relative to the feeding port is to prevent a person from falling into the vessel body when feeding.

[0008] It also includes a mounting frame, on which a motor is mounted. One end of the motor is equipped with a stirring rod, which is driven to rotate by the motor. The stirring rod is equipped with a first stirring plate and a second stirring plate.

[0009] Both the first and second stirring blades are tilted, and the tilt angles of the first and second stirring blades are opposite. This design is for better mixing.

[0010] This utility model discloses an internal heating vessel, in which a heating coil is installed inside the vessel body for heating, thereby improving heating efficiency. In addition, most existing heating coils are single coils that are wound downwards to the liquid outlet. However, in this case, a lot of material remains on the coil. This application adopts a U-shaped coil plus a vertical straight pipe, that is, the main heating part in the middle is a vertical straight pipe, which makes it less likely for material to remain.

[0016] The following is combined Figure 1-4 Further explanation:

[0017] An internal heating vessel includes a vessel body 1. A circular coil frame 2 is respectively provided on the upper and lower parts of the vessel body 1. A heating coil 3 is provided on the circular coil frame 2. The heating coil 3 includes a U-shaped coil 31, and the U-shaped coil 31 includes a retaining ring 311. The retaining ring 311 is welded and fixed to the circular coil frame 2. The heating coil 3 includes an inlet pipe 32, an outlet pipe 33, and several repeatedly arranged coil units (the heating coil 3 contains hot water). Each coil unit includes a U-shaped coil 31 and a vertical straight pipe 34, and the U-shaped coils 31 of two adjacent coil units have opposite directions.

[0018] The U-shaped coil 31 and the vertical straight pipe 34 are welded together. This method can be used when the heating vessel requires almost no disassembly.

[0019] The vessel body 1 is equipped with a feeding port 4, and a baffle 5 is installed inside the vessel body 1. The feeding port 4 and the baffle 5 are configured in conjunction. The position of the baffle 5 relative to the feeding port 4 is to prevent a person from falling into the vessel body 1 when feeding materials.

[0020] It also includes a mounting frame 6, on which a motor 7 is mounted. One end of the motor 7 is equipped with a stirring rod 8, which is driven to rotate by the motor 7. The stirring rod 8 is equipped with a first stirring plate 9 and a second stirring plate 10.

[0021] Both the first stirring blade 9 and the second stirring blade 10 are tilted, and the tilt angles of the first stirring blade 9 and the second stirring blade 10 are opposite. The above design is for better mixing.

[0022] This embodiment describes an internally heated vessel. A heating coil 3 is installed inside the vessel body 1 for heating, thereby improving heating efficiency. In addition, most existing coils are single coils that are wound downwards in circles until the liquid outlet. However, in this case, a lot of material remains on the coil. This application adopts a U-shaped coil 31 plus a vertical straight pipe 34, that is, the main heating part in the middle is the vertical straight pipe 34, which makes it less likely for material to remain. Example 2

[0023] Everything else is the same as in Example 1, except that the retaining ring 311 is fixed to the annular coil frame 2 by bolts, and the U-shaped coil 31 has internal threads at both ends, the vertical straight pipe 34 has external threads at both ends, and the U-shaped coil 31 and the vertical straight pipe 34 are connected by threads.

[0024] If the heating vessel needs to be disassembled, this embodiment can be used. The threaded connection allows for easy segmented installation and disassembly of the heating coil.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
