Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, specifically to a heating and stirring vessel. Background Technology

[0002] Cathodic electrophoretic coatings are widely used for the protection of various metal workpieces due to their excellent anti-corrosion performance, uniform coating ability, environmental friendliness, and low VOC emissions.

[0003] The production process requires the use of a heated stirring tank. However, the existing heated stirring tank uses a jacket for heating. Since the production of cathodic electrophoretic coatings requires the use of resin materials, we have found that the jacket method is not ideal for heating resin materials.

[0004] Therefore, we hope to develop a heated stirring vessel that can solve the above problems. Summary of the Invention

[0005] This utility model aims to provide a heated stirring vessel, the specific solution of which is as follows:

[0006] A heated stirring vessel includes a reactor body, the reactor body comprising a main body and a jacket, the jacket containing a heating coil, the main body containing a plurality of support rods, and a heat medium spiral coil mounted on the support rods, the heat medium spiral coil comprising an inlet section, an outlet section and a spiral section, the spiral section having a height difference.

[0007] The inlet and outlet sections are located at the same vertical position. This design ensures a more orderly pipeline layout.

[0008] The support rod has several openings. The openings facilitate the flow of materials.

[0009] There are two heat transfer medium spiral coils, located at the top and bottom of the main body respectively. An internal partition separates the heat transfer medium spiral coil at the bottom of the reactor body. The middle section is not suitable for a heat transfer medium spiral coil due to the agitation mechanism; therefore, only a top and bottom design are provided. Furthermore, since material flow into the bottom heat transfer medium spiral coil would hinder agitation, it is also isolated.

[0010] It also includes a mounting frame, on which a motor is mounted, the motor being connected to a stirring rod, and the motor driving the stirring rod to rotate.

[0011] The stirring rod includes a first stirring element and a second stirring element. The first stirring element includes a first horizontal bar and a first vertical bar, and the second stirring element includes a second horizontal bar and a second vertical bar. Both the first and second stirring elements are spaced apart from the heat medium spiral coil. In practice, the first and second vertical bars of this design are close to the inner wall of the main body, which can increase the stirring effect while ensuring that they do not collide with the heat medium spiral coil.

[0012] One end of the first horizontal bar is connected to the bottom of the first vertical bar, and both ends of the second horizontal bar are connected to the top of the first vertical bar. This ensures better mixing.

[0013] This utility model relates to a heating and stirring vessel. In addition to the outer jacket of the main body, a spiral coil of heat medium is also added inside the main body, which achieves a good heating effect without affecting the stirring process. Attached Figure Description

[0019] The following is combined with Figure 1-4 Further explanation:

[0020] A heating and stirring vessel includes a reactor body, which includes a main body 1 and a jacket 2. The jacket 2 is provided with a heating coil 3 (containing hot water). The main body 1 is provided with several support rods 6, and the support rods 6 are provided with a heat medium spiral coil 5 (containing hot water). The heat medium spiral coil 5 includes an inlet section 51, an outlet section 52 and a spiral section 53, and the spiral section 53 has a height difference.

[0021] The inlet section 51 and the outlet section 52 are located at the same vertical position (and in practice, the inlet section 51 and the outlet section 52 also pass through the gap between the heating coils in the jacket 2). This design ensures a more orderly piping arrangement.

[0022] The support rod 6 has several openings 61. The openings 61 facilitate the flow of materials.

[0023] There are two heat medium spiral coils 5, located at the upper and lower parts of the main body 1, respectively. The main body 1 also has an internal partition 7 that isolates the heat medium spiral coil 5 at the bottom of the reactor. The middle part is not suitable for the heat medium spiral coil 5 due to the agitation mechanism; therefore, only the top and bottom sections are designed. Furthermore, since the bottom heat medium spiral coil 5 is unsuitable for agitation if material flows in, it is also isolated.

[0024] It also includes a mounting frame 8, on which a motor 9 is mounted. The motor 9 is connected to a stirring rod 10, and drives the stirring rod 10 to rotate. The stirring rod 10 includes a first stirring element 11 and a second stirring element 12. The first stirring element 11 includes a first horizontal bar 111 and a first vertical bar 112, and the second stirring element 12 includes a second horizontal bar 121 and a second vertical bar 122. Both the first stirring element 11 and the second stirring element 12 are spaced apart from the heat medium spiral coil 5. In practice, the first vertical bar 112 and the second vertical bar 122 of this design are close to the inner wall of the main body 1, which can increase the stirring effect while ensuring that they do not collide with the heat medium spiral coil 5. One end of the first horizontal bar 111 is connected to the bottom of the first vertical bar 112, and one end of the second horizontal bar 121 is connected to the top of the second vertical bar 122, ensuring better stirring.

[0025] This utility model discloses a heating and stirring vessel. In addition to the outer jacket 2 of the main body 1, it also incorporates a heat medium spiral coil 5 inside the main body 1, which achieves a good heating effect without affecting the stirring process. Specifically, this utility model is equipped with two sets of heat medium spiral coils 5. The middle position is not suitable for the heat medium spiral coil 5 due to the design of the stirring mechanism, so only the top and bottom positions are designed. Furthermore, since the bottom heat medium spiral coil 5 is unsuitable for stirring if material flows in, it is isolated separately.

[0026] 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.
