[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0021] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0022] In recent years, with the rapid development of science and technology, new heating electrode device materials such as carbon fiber and graphene have gradually entered people's field of vision. These materials have the advantages of high efficiency, energy saving, and environmental protection, bringing new development opportunities for heating electrode device technology. At the same time, the combination of heating electrode devices and intelligent control technology is becoming increasingly close, realizing precise control and intelligent management of the heating process.

[0023] Existing heating electrode devices generally adopt a fixed mode, that is, the heating body is fixedly connected to the heating electrode device to ensure the heat transfer effect. However, this structure does not have the characteristic of quick disassembly. On the other hand, the heating electrode device generally has an additional cooling mechanism, such as water cooling or air cooling. Taking water cooling as an example, each time the heating element is disassembled with the existing fixed structure, the water cooling pipes on the electrode need to be removed one by one before the electrode can be rotated to remove the heating element, which makes the workflow of replacing the heating element in the production process complicated and time-consuming, and increases the risk of staff missing parts. In addition, when the fixed structure heating electrode device is heating the heating element, the cooling mechanism usually interferes with the conductive module used for heating, causing leakage.

[0024] Therefore, it is urgent to design a heating electrode device to solve the above-mentioned problems of rapid disassembly and leakage of the heating electrode device.

[0025] Please refer to the attached Figure 1 To Attachment Figure 4 A heating electrode arrangement of the present invention is described.

[0026] Figure 1 is a schematic structural diagram of the heating electrode device of this embodiment; Figure 2 2 is a cross-sectional view of the heating electrode device of this embodiment.

[0027] This embodiment provides a heating electrode device, such as Figure 1 and Figure 4 As shown, the heating electrode device is used to heat the heating element (the heating element is not shown), and the heating electrode device includes an electrode and a cooling component 4 arranged on the electrode, the electrode includes: a mounting seat 3 and a rotating shaft 2 rotatably arranged on the mounting seat 3, the cooling component 4 is installed on the mounting seat 3, wherein the rotating shaft 2 is rotatably arranged on the mounting seat 3 through a first end, and the second end of the rotating shaft 2 is detachably connected to the heating element, so that the heating element and the rotating shaft can be disassembled by rotating the rotating shaft 2 on the mounting seat 3.

[0028] The heating electrode device is detachably connected to the heating element through the rotating shaft 2, which solves the above-mentioned existing technical problems and can effectively reduce the undesirable phenomena such as cumbersome operation, long time consumption, and possible installation omission of the heating element. Among them, the mounting seat 3 is used to abut against the rotating shaft 2 and transmit current through the rotating shaft 2 of the electrode to ensure the electrical connection between the mounting seat 3 of the electrode and the heating element, thereby achieving the purpose of conductive heating and having the characteristic of supplying power to the heating element for normal operation; The heating electrode device is arranged on the mounting seat 3 by rotating the rotating shaft 2. When the heating element and the rotating shaft 2 need to be disassembled, the rotating shaft 2 can be directly rotated to separate the rotating shaft 2 from the heating element. Compared with the existing installation method, the heating element that cooperates with the heating electrode device can be disassembled simply and conveniently. The heating electrode device uses the cooling component 4 to cool down, so as to avoid the reduction of the service life or even damage of the rotating shaft 2 and the mounting seat 3 due to conductive heat generation, and realizes the direct rotation and disassembly of the rotating shaft 2 and the heating element without moving the cooling component 4.

[0029] Furthermore, the mounting seat 3 has a central axis, and a mounting groove is provided on the upper part of the mounting seat 3 along the central axis. One end of the rotating shaft 2 is inserted into the mounting groove, and a self-lubricating bearing 63 is sleeved on the rotating shaft 2 and located between the inner wall of the mounting groove and the rotating shaft 2, so that when the rotating shaft 2 rotates relative to the mounting seat 3, the central axis is coaxial with the axis of the rotating shaft 2.

[0030] Furthermore, the bottom of the mounting groove corresponds to the shape of the end of the rotating shaft 2 .

[0031] Optionally, the bottom of the mounting groove is hemispherical. Further, in order to match the bottom shape of the mounting groove, the end shape of the rotating shaft 2 also needs to be set to a hemispherical surface. It can be understood that the shape of the mounting groove and the rotating shaft 2 can also be replaced by a cylindrical, conical, etc.

[0032] It should be noted that the cooling component 4 includes a cooling medium, and the cooling component 4 is used to pass the cooling medium into the accommodating cavity 21 to achieve a cooling effect.

[0033] Furthermore, the interior of the rotating shaft 2 is provided with a longitudinal accommodating cavity 21 extending along the axis of the rotating shaft 2, and the cooling component 4 includes a longitudinal pipe, which passes through the mounting seat 3 and the bottom of the rotating shaft 2 and is inserted into the accommodating cavity 21. The outer wall of the pipe is spaced apart from the inner circumferential wall of the accommodating cavity 21 to form a reflux passage connected to the outlet of the pipe, and the mounting seat 3 and the rotating shaft 2 are provided with an outflow passage 31 connected to the reflux passage. By arranging the cooling component 4 from bottom to top, it is ensured that the cooling medium can first reach the top of the accommodating cavity 21, and then be discharged through the accommodating cavity 21 and the outflow passage 31 in sequence, thereby increasing the path of the cooling medium as much as possible, ensuring that the cooling medium can fully contact the rotating shaft 2 and the mounting seat 3, and thus improving the cooling effect.

[0034] Furthermore, if Figure 1 As shown, a threaded portion 22 is provided at one end of the rotating shaft 2, wherein the threaded portion 22 is provided at the end of the rotating shaft 2 away from the mounting seat 3, and the threaded portion 22 is used to connect with the heating element.

[0035] Optionally, the material of the rotating shaft 2 is set to be a metal material such as copper, iron, etc. In addition, those skilled in the art may adopt other materials with stronger conductive properties according to common knowledge or existing technologies, and this embodiment does not make specific limitations.

[0036] Furthermore, the central axes of the accommodating chamber 21 and the pipeline are both coincident with the central axis of the rotating shaft 2; the upper end of the pipeline is spaced apart from the top of the accommodating chamber 21 and is close to the second end of the rotating shaft 2; the outflow channel 31 is arranged close to the first end of the rotating shaft 2; the mounting seat 3 is provided with a first through hole connected to the mounting groove along its central axis, and the rotating shaft is provided with a second through hole connected to the first through hole along the axis of the rotating shaft 2 at the first end; the pipeline is inserted into the accommodating chamber 21 through the first through hole and the second through hole.

[0037] Furthermore, the cooling assembly 4 is detachably mounted on the lower part of the mounting seat 3 through a locking device; a sealing device is provided on the mounting seat 3 to prevent the cooling medium from leaking from the mounting groove and the first through hole, and the sealing device includes a skeleton oil seal 64 which is sleeved on the rotating shaft 2, located below the self-lubricating bearing 63 and between the inner wall of the mounting groove and the rotating shaft 2, and a pipe seal 72 which is sleeved on the pipe. The seal 72 is clamped by the locking device to seal the gap between the pipe and the inner wall of the first through hole.

[0038] Specifically, Figure 2 As shown, the locking device 7 includes a locking member 71, which is sleeved on the outer wall of the cooling component 4 and connected to the mounting seat 3 to fix the cooling component 4 on the mounting seat 3. A sealing member 72 is arranged inside the locking member 71, and the sealing member 72 is attached to the inner wall of the cooling component 4 to prevent the cooling medium from flowing back and escaping from the accommodating cavity 21.

[0039] In the actual production process, please refer to Figure 1 , Figure 3 and Figure 4 , take vertical installation as an example: first assemble the first sealing unit 61 with the mounting seat 3, the skeleton oil seal 64, the self-lubricating bearing 63, and the locking assembly for use, then install the second sealing unit 62 with the external cavity flange, and then insert the rotating shaft 2 from the external cavity flange from top to bottom, pass through the first sealing unit 61, the self-lubricating bearing 63 and the skeleton oil seal 64, and then enter the mounting seat 3, and then connect the first clamping flange 51 with the external cavity flange, and then tighten the clamping piece 53, and finally, insert the cooling assembly 4 into the accommodating cavity 21 and then lock the locking assembly to ensure that the cooling assembly 4 does not slip out of the accommodating cavity 21; In addition, if the upper and lower positions of the rotating shaft 2 need to be adjusted, or the rotating shaft 2 needs to be disassembled, the first clamping flange 51 and the second clamping flange 52 and the clamping member 53 can be loosened. At this time, in order to prevent the mounting seat 3 from being separated from the mounting seat 3 due to accidental touch, the staff can hold the mounting seat 3 with their hands, and then twist the rotating shaft 2 to adjust the position of the rotating shaft 2. It should be noted that the process of adjusting or disassembling the heating element is also equivalent to the process of loosening the rotating shaft 2. If the above disassembly method is adopted, then in the process of disassembling the heating element, the cooling component 4 and the mounting seat 3 are usually fixed together with the mounting seat 3. It is only necessary to rotate the rotating shaft 2 to achieve the purpose of quickly replacing the heating element, and there is no need to close the cooling component 4 and the mounting seat 3.

[0040] Further, Figure 3 Schematic diagram of the structure of the clamping assembly of this embodiment; Figure 3 As shown, the heating electrode device further includes a clamping assembly for clamping the rotating shaft 2 and the mounting seat 3 in the axial direction of the rotating shaft 2 .

[0041] Specifically, the clamping assembly includes a first clamping flange 51, a second clamping flange 52, and a clamping member 53 connecting the first flange and the second flange, which are arranged horizontally along the axis. The first clamping flange 51 surrounds the rotating shaft 2 and is connected to an external element to position the first clamping flange 51. The second clamping flange 52 abuts against the protruding outer edge of the mounting seat 3. The clamping member 53 can adjust the distance between the second flange and the first flange, so that the rotating shaft 2 and the mounting seat 3 can be clamped or loosened in the axial direction of the rotating shaft 2.

[0042] The clamping assembly clamps the rotating shaft 2 and the mounting seat 3 so that the rotating shaft 2 abuts against the mounting seat 3, thereby achieving power supply and ensuring that a stable current passes through the heating element connected to the rotating shaft 2, thereby performing a heating operation. When disassembly is required, the first clamping flange 51 and the second clamping flange 52 can be loosened, and then the rotating shaft 2 is rotated to separate the rotating shaft 2 from the heating element. That is to say, compared with the traditional heating electrode device, the present embodiment splits the heating electrode device with a fixed structure in the prior art into a freely rotating rotating shaft 2 and a mounting seat 3 for providing current, thereby achieving the purpose of only removing the electrode without removing the cooling structure on the electrode, thereby achieving the purpose of quickly and easily replacing the top heating element. In addition, the clamping assembly can prevent the heating electrode device from shaking during operation, so that the electrode can achieve the purpose of stable operation.

[0043] Optionally, in order to prevent the mounting base 3 from being directly connected to the accommodating cavity 21, in this embodiment, the material of the first clamping flange 51 and the second clamping flange 52 are both set to be insulating acrylic material. In other embodiments, the material of the first clamping flange 51 and the second clamping flange 52 can also be plastic or rubber, etc., which is not specifically limited here.

[0044] It can be understood that the above-mentioned clamping piece 53 is used in conjunction with the first clamping flange 51 and the second clamping flange 52. After the clamping piece 53 is locked, the rotating shaft 2 is in close contact with the mounting seat 3, thereby achieving stable power transmission. At the same time, it can also cooperate with other components to improve the stability of the heating electrode device structure, so that the heating electrode device as a whole is not easy to slip; when the heating element needs to be replaced, the clamping piece 53 needs to be loosened, and then the rotating shaft 2 is loosened until the rotating shaft 2 and the heating element are separated and fall off from each other, thereby completing the disassembly. When installation is required, the above operation is reversed, that is, the rotating shaft 2 is screwed first and then the clamping piece 53 is locked, and no additional details are given.

[0045] Specifically, the clamping assembly also includes a locking nut that cooperates with the clamping piece 53. The locking nut is arranged at the bottom of the clamping piece 53. When loosening or clamping is required, it can be achieved through the locking nut that cooperates with the bottom of the clamping piece 53.

[0046] Furthermore, an avoidance hole 54 is provided on the first clamping flange 51 and the second clamping flange 52, and the width of the avoidance hole 54 is greater than the outer diameter of the rotating shaft 2, so as to facilitate the passage of the rotating shaft 2; the clamping member 53 includes a plurality of locking bolts and nuts matching therewith, and the threaded ends of the bolts are connected to the corresponding nuts through through holes provided on the first clamping flange 51 and the second clamping flange 52, and the distance between the first clamping flange 51 and the second clamping flange 52 in the axial direction is adjusted through the cooperation between the nuts and the bolts.

[0047] It is understandable that when the staff performs assembly, they can first assemble the rotating shaft 2, the mounting seat 3, etc., and then realize the installation of the first clamping flange 51 and the second clamping flange 52 through the avoidance hole 54. They can also first install the first clamping flange 51 and the second clamping flange 52 with the rotating shaft 2, that is, adopt a sleeve arrangement, and then assemble the rotating shaft 2 with the mounting seat 3, etc. In other words, the setting of the avoidance hole 54 enables the staff to not have to follow a fixed order, making the installation process more flexible.

[0048] Further, Figure 4 is an exploded view of the heating electrode device of this embodiment, as shown in Figure 1 , Figure 3 and Figure 4 As shown, the heating electrode device also includes a sealing component, which is sleeved on the outer wall of the rotating shaft 2; the sealing component includes a first sealing unit 61, which is sleeved on the outer wall of the rotating shaft 2 and is arranged at the connection between the accommodating chamber 21 and the outflow channel 31, for blocking the cooling medium; the sealing component includes a second sealing unit 62, which is sleeved on the outer wall of the rotating shaft 2. It should be noted that the first sealing unit 61 is to prevent the cooling medium in the accommodating chamber 21 from overflowing when it refluxes, so as to achieve the sealing of the return water inside the electrode; the second sealing unit 62 can be connected with other parts of the device to achieve the vacuum sealing between the heating electrode device and other parts of the device.

[0049] Specifically, Figure 2 and Figure 4 As shown, the sealing assembly also includes a self-lubricating bearing 63 and a skeleton oil seal 64, wherein the self-lubricating bearing 63 is made of brass and graphite, with the aim of allowing the rotating shaft 2 to remain coaxial with the mounting seat 3 and not easily shake, thereby ensuring the stability of the working process of the heating element. At the same time, during the process of disassembling the heating element, the rotating shaft 2 can be directly screwed, which is convenient for operation; the skeleton oil seal 64 can achieve a return water seal inside the accommodating chamber 21, and is usually used in conjunction with the first sealing unit 61.

[0050] Specifically, the sealing assembly also includes an external connecting flange 65. It should be noted that the external connecting flange 65 is an external part that needs to cooperate with the heating electrode device and is usually located in the equipment cavity or on the bottom cover. In this embodiment, there is a sealing ring inside the external connecting flange 65, which is usually cooperated with the second sealing unit 62 to achieve vacuum sealing of the cavity.

[0051] As a preferred embodiment, the above-mentioned cooling medium can be drinking water or purified water, etc. Specifically, the conductivity of water mainly depends on the ion content inside it. Among them, the conductivity of pure water is very poor because the number of freely moving ions inside it is extremely small; water in daily life usually contains minerals and impurities, and these impurities dissociate into ions in the water, making the water conductive, but in the cooling component 4, the water is not in direct contact with these ions, so it will not conduct electricity.

[0052] In addition, it can be understood by those skilled in the art that when the high-voltage current flows through the rotating shaft 2 and the heating element through the mounting seat 3, an electric field will be generated around the rotating shaft 2, causing the water molecules to be instantly polarized and form a tiny electric dipole. However, this process is extremely rapid, and the charge will not stay in the water molecules, but will be quickly transferred to the surface of the rotating shaft 2. Secondly, due to the extremely low electrical conductivity of water itself, the charge cannot move freely in the water and can only flow on the surface of the rotating shaft 2, so the water will not form a conductive path. Furthermore, the mounting seat 3 is located at one end connected to the mounting seat 3 and is provided with a water-cooled cable, and the water-cooled cable must be grounded when used, so that the charge on the surface of the rotating shaft 2 can be safely introduced into the ground through the ground wire, avoiding the potential threat of current to personnel. In summary, the water-cooled cable ensures that the internal water will not conduct electricity through its unique design and grounding measures, effectively maintains electrical safety, and overcomes the problem that the heating electrode device in the prior art may have leakage.

[0053] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
