Description

Technical Field

[0001] The present invention relates to the technical field of titanium anode coating preparation, and specifically to an anti-corrosion titanium anode coating preparation device and a preparation method thereof. Background Art

[0002] In the fields of materials science and industrial manufacturing, a segmented temperature-controlled sintering furnace is widely used in the heat treatment process of various materials, especially playing a key role in the titanium anode coating preparation process. Through precise segmented temperature control operations, it can effectively improve the organizational structure of the coating, significantly enhance the densification and performance stability of the coating, so as to meet the special performance requirements of titanium anode coatings in different industrial scenarios.

[0003] However, currently, the segmented temperature-controlled sintering furnace faces many technical problems that need to be urgently solved in the fixed support and installation of heating elements. The traditional fixing method of heating elements mainly relies on connecting components such as ceramic insulators, nuts, and screws to fasten the heating rods; in the high-temperature working environment of the segmented temperature-controlled sintering furnace, due to the continuous action of the thermal expansion and contraction effect, these connecting components are extremely prone to loosening; once the connecting components become loose, the position stability of the heating rods cannot be effectively guaranteed, thus triggering a series of serious problems; the deviation of the heating rod position will cause uneven temperature distribution in the furnace chamber, resulting in inconsistent heating of the titanium anode coating during the sintering process, directly affecting the quality and performance uniformity of the coating and reducing the yield rate of the product; on the other hand, the loose heating rods will collide or rub against other components during operation, accelerating the damage of the heating rods themselves and causing damage to the internal structure of the furnace chamber.

[0004] Meanwhile, during the operations of vacuum pumping and introducing protective gas, the drawbacks of the existing technology are further highlighted. When the gas rushes into the furnace chamber rapidly, it will instantly cause a large amplitude of air vibration; the above-mentioned strong vibration will seriously affect the fixing stability of the silicon carbide heating rods. Even if the heating rods are well fixed during the initial installation, after multiple gas impacts, they are prone to loosening and displacement; moreover, the existing technology has obvious defects in terms of fixing and maintenance for this problem, lacking effective countermeasures and being unable to detect and repair the loosening of the fixing components caused by vibration in a timely manner, bringing great potential hazards to the long-term stable operation of the equipment.

[0005] In addition, the installation method of the existing heating rods has poor convenience. During the daily maintenance of the equipment, the replacement of heating rods, and the equipment overhaul process, operators need to spend a lot of time and effort to disassemble and install the heating rods. The complex installation steps not only reduce work efficiency but also increase labor costs. In some industrial production scenarios with high requirements for production continuity, the problem of poor installation convenience of heating rods is particularly prominent. Once a heating rod fails and needs to be replaced, the long downtime for installation will cause production interruption and result in huge economic losses.

[0006] In summary, the existing technology for fixing and installing heating elements in segmented temperature-controlled sintering furnaces has become a bottleneck restricting the development of the titanium anode coating preparation process. There is an urgent need to develop a new fixing and installing technology to solve the problems of loosening caused by thermal expansion and contraction, gas impact affecting stability, and poor installation convenience, and to meet the requirements of modern industry for efficient, stable, and high-quality production.

[0007] Therefore, the present invention proposes an anti-corrosion type titanium anode coating preparation device to solve the above problems. Summary of the Invention

[0008] In view of this, the technical problem to be solved by the present invention is to propose an anti-corrosion type titanium anode coating preparation device to solve the problems existing in the prior art.

[0009] To achieve the above object, the present invention provides the following technical solution: an anti-corrosion type titanium anode coating preparation device, comprising: a segmented temperature-controlled sintering furnace, a closed door panel, a furnace chamber, a substrate support, the closed door panel is arranged on the segmented temperature-controlled sintering furnace through a rotating shaft, the furnace chamber is fixedly connected inside the segmented temperature-controlled sintering furnace, the substrate support is fixedly connected inside the furnace chamber, and further comprising: a multi-dimensional dynamic balance anti-interference and stabilizing component, a temperature processing redundancy guarantee component, the temperature processing redundancy guarantee component is arranged inside the multi-dimensional dynamic balance anti-interference and stabilizing component; the multi-dimensional dynamic balance anti-interference and stabilizing component is used to maintain the stability of the silicon carbide heating rod during the processes of thermal expansion and contraction, vacuum pumping, and introducing protective gas; the temperature processing redundancy guarantee component is used to maintain the stability of the components of the device at high temperatures.

[0010] As an improvement, the multi-dimensional dynamic balance anti-interference and stabilizing component includes an attached arc body attached and fixedly connected to the inner wall of the furnace chamber, the tail end of the attached arc body is fixedly communicated with a connecting member, and the bottom end of the connecting member is fixedly communicated with a fixed groove body.

[0011] As an improvement, a moving plate is slidably connected inside the attached arc body, a connecting rod is fixedly connected to the end face of the moving plate, a triangular block is fixedly connected to the end of the connecting rod away from the moving plate, a spring A is fixedly connected to the inner wall of the attached arc body, and a clamping and restricting strip plate is fixedly connected to the bottom end of the spring A.

[0012] As an improvement, a sliding plate is slidably connected inside the fixed groove body, an auxiliary groove is opened at the bottom end of the fixed groove body, the length of the auxiliary groove is less than the total length of the fixed groove body, a limiting groove is opened at the outer end of the sliding plate, tapered grooves are symmetrically opened at the tail end of the limiting groove, and a positioning pin is fixedly connected to the fixed groove body.

[0013] As an improvement, the temperature treatment redundancy guarantee component includes a redundancy degree regulating plate slidably connected inside the attaching arc body. A spring B is fixedly connected to the redundancy degree regulating plate. A sleeve is fixedly connected to the redundancy degree regulating plate. A sliding piece is slidably connected inside the sleeve. Through holes are equidistantly formed in the sliding piece. A plugging column is fixedly connected to the sliding piece. One end of the plugging column away from the sliding piece is fixedly connected to the moving plate.

[0014] As an improvement, a ceramic insulating part is fixedly connected to the bottom surface of the sliding plate. A ceramic tube is inserted and fixedly connected inside the ceramic insulating part.

[0015] As an improvement, a silicon carbide heating rod is inserted into the ceramic insulating part. A clamping groove is formed in the ceramic tube. A shape memory alloy clamping strip is clamped in the clamping groove of the ceramic tube.

[0016] As an improvement, a preparation method for an anti-corrosion titanium anode coating includes the following steps: preliminary preparation, installation of temperature control components, heating stage, heat preservation stage, cooling stage, taking out the workpiece, and detection and treatment; the preliminary preparation step includes: placing the titanium anode substrate that has undergone pretreatment and coating deposition on a high-temperature-resistant substrate support, checking whether the furnace chamber is clean without residue of sundries, connecting the protective gas gas source to ensure normal gas supply, and setting the parameters of the temperature control system, including the temperature, heating rate, heat preservation time, and cooling rate of each stage; the installation step of the temperature control components includes: sliding the sliding plate with the silicon carbide heating rod into the fixed groove body. Under the connection of the communicating attaching arc body, communicating part, and fixed groove body, the gas inside indirectly assists in clamping and restricting the strip plate to perform a clamping operation on the sliding plate with the silicon carbide heating rod under the setting of the restricting groove.

[0017] The heating stage step includes: starting the segmented temperature control sintering furnace, and the temperature control system controls the silicon carbide heating rod to start heating, slowly raising the furnace chamber temperature at a preset heating rate. During this process, volatile substances such as moisture and organic substances in the coating gradually volatilize and are discharged; the heating rate is controlled at 1 to 5 °C / min; the heat preservation stage step includes: when the furnace chamber temperature reaches the preset heat preservation temperature, maintaining this temperature for a period of time.

[0019] Compared with the prior art, the present invention provides an anti-corrosion titanium anode coating preparation device, which has the following beneficial effects: 1. Through the design of the multi-dimensional dynamic balance anti-interference and stabilization component, the following advantages can be brought: overcoming the influence of thermal expansion and contraction and having an adaptive adjustment function: in the traditional bolt fixing method, due to the different thermal expansion coefficients of the connecting piece and the heating rod when the temperature changes, stress concentration is likely to occur, resulting in loosening; while the multi-dimensional dynamic balance anti-interference and stabilization component uses gas assistance design and can indirectly and dynamically adjust the limiting stability of the silicon carbide heating rod according to temperature changes; when the temperature rises, the gas in the attachment arc body increases in pressure due to thermal expansion, indirectly causing the limiting part to adaptively move the clamping limiting strip and cooperate with the limiting groove, which not only indirectly maintains the stability of the silicon carbide heating rod but also avoids abnormal movement of the components caused by temperature factors to the stable silicon carbide heating rod; when the temperature drops, the gas contracts, and the limiting part adjusts inward accordingly, that is, it contracts into the attachment arc body, but it will always cooperate with the limiting groove on the sliding plate to maintain the limit, effectively reducing problems with the fixing stability caused by thermal expansion and contraction, thereby indirectly causing displacement of the silicon carbide heating rod and ensuring uniform temperature distribution in the furnace chamber.

[0020] Flexible buffering: This component uses the cooperation of triangular blocks, clamping limiting strips, and gas. During the process of thermal expansion and contraction, the triangular block can play a buffering role to a certain extent through the pushing of its inclined plane on the clamping limiting strip, absorbing the stress generated by temperature changes. In contrast, the traditional bolt fixing lacks this flexible buffering mechanism and is prone to loosening under stress accumulation, indirectly causing the position of the silicon carbide heating rod to shift, resulting in uneven temperature and affecting the quality of the titanium anode coating.

[0021] Improving comprehensive benefits and product quality: By ensuring the stability of the silicon carbide heating rod under various conditions and reducing the uneven temperature caused by the displacement of the silicon carbide heating rod, the quality of the titanium anode coating can be significantly improved; and the stable heating environment makes the coating structure more uniform and denser during the sintering process, thereby improving the performance stability of the coating, such as enhancing the anti-corrosion ability and conductivity of the coating to meet the requirements of higher-standard industrial applications.

[0022] Reducing equipment maintenance costs: Due to easy loosening and being greatly affected by gas impact, the traditional fixing method requires frequent inspections and maintenance, increasing equipment maintenance costs and downtime; the high stability of the multi-dimensional dynamic balance anti-interference and stabilizing component greatly reduces the failures caused by the loosening and displacement of the heating rod, reducing the equipment maintenance frequency. This not only saves the human and material resources required for maintenance but also reduces production losses caused by downtime maintenance, improving production efficiency.

[0023] 2. By adopting the clamping limit strip, limit groove, tapered groove, and alignment pins, the present invention can bring the following benefits under various dimensional working conditions: Enhancing the stability during the vacuum pumping stage: During the vacuum pumping process, the rapid change of air pressure in the furnace chamber will cause vibrations. The cooperation between the clamping limit strip and the limit groove plays a key role. The clamping limit strip tightly fits into the limit groove of the sliding plate, and the precise cooperation between the two forms multi-directional constraints; when vibrations occur, the clamping limit strip in the limit groove can effectively block the displacement of the silicon carbide heating rod in the horizontal direction, suppressing its swaying in the transverse and longitudinal directions; at the same time, the combination of the tapered groove and the alignment pins further strengthens this stability. The alignment pins are accurately inserted into the tapered groove. Using the characteristics of the tapered structure, they automatically adjust and maintain the center positioning of the sliding plate during vibrations. Even when subjected to vibration impact forces from different directions, the tight contact and self-adaptive adjustment ability between the tapered groove and the alignment pins can ensure that the silicon carbide heating rod connected to the sliding plate remains stable in the vertical direction, effectively ensuring the stable operation of the heating system.

[0024] Optimizing the performance during the stage of introducing protective gas: When introducing the protective gas, the high-speed gas flow will impact the fixation of the silicon carbide heating rod, affecting its stability; the tight clamping relationship between the clamping limit strip and the limit groove provides strong anti-impact ability; the sliding friction between the clamping limit strip in the limit groove and their tight cooperation enable the silicon carbide heating rod to disperse the impact force to the entire limit structure when subjected to the gas flow impact, avoiding the displacement caused by the single-point force of using bolts for fixation in the prior art; while the tapered groove and the alignment pins play a role in enhancing the positioning accuracy at this time; ensuring its stable operation during the introduction of the protective gas and maintaining a uniform heating environment in the furnace chamber, which helps improve the quality of the titanium anode coating.

[0025] Ensuring the uniformity of temperature connection between processes and improving the coating quality: By reducing the displacement of the silicon carbide heating rod in different working stages, the stable position of the silicon carbide heating rod ensures uniform heat distribution in the furnace chamber, avoiding local overheating or overcooling phenomena caused by the displacement of the silicon carbide heating rod in different process stages, stabilizing the temperature connection between processes; helping the elements in the coating to fully diffuse and react, enhancing the bonding force between the coating and the substrate, and improving the corrosion resistance of the coating.

[0026] 3. Through the design of the temperature treatment redundancy protection component, the present invention can provide strong support in many aspects for the stable operation of the device in a high-temperature environment, which is of great significance for improving the overall performance of the device, extending its service life, and ensuring the continuity of production and product quality. The benefits are as follows: enhancing component stability and preventing non-operational movement of the main components. High temperature may cause thermal stress in the main components of the device, and the material properties of each component of the device will undergo volume changes. The temperature treatment redundancy protection component can regulate the components in an active or passive manner to ensure that each component does not experience displacement or deformation in a non-operational state within the corresponding temperature range, thereby triggering non-operational movement, such as displacement and vibration. This component can suppress these movements through buffering and restraint methods, ensuring that each component can still maintain the correct relative position and working attitude at high temperature and maintaining the functional integrity of the device.

[0027] Ensuring the functional reliability of the device: During the preparation process of the titanium anode coating, the accuracy of temperature control and the stability of components are crucial for the coating quality. The temperature treatment redundancy protection component ensures the stable operation of the device at high temperature, avoiding fluctuations and deviations in the positions of components caused by temperature problems, thereby indirectly ensuring the consistency and performance of the coating and effectively reducing the rejection rate.

[0028] Enhancing system safety and improving production continuity: If component damage or functional failure occurs in a high-temperature device, there is a risk of triggering safety accidents. This component effectively reduces these risks by ensuring component stability and preventing functional failure, protecting the safety of operators and the production environment. At the same time, reducing component damage and functional failure means shorter equipment downtime, higher production efficiency, long-term stable operation of the device, and reduced production interruptions caused by equipment failures, effectively improving the production efficiency and economic benefits of the enterprise.

[0029] 4. Through the use of the clamping limit strip, the limit groove, the conical groove, the alignment pin, and the cooperation of the gas, the present invention can bring benefits different from the existing installation methods in terms of installation, improving the convenience of installation and maintenance. That is, during the installation of the silicon carbide heating rod, the installer only needs to push the sliding plate with the silicon carbide heating rod, and the sliding plate can push the gas in the attached arc body, the connecting member, and the fixed groove to move. Indirectly, the clamping limit strip is matched with the limit groove to limit and fix the sliding plate with the silicon carbide heating rod. During this process, the design of the conical groove and the alignment pin can assist in more precise installation. The above-mentioned clamping method of the clamping limit strip and the limit groove, and during operation, in cooperation with gas expansion, further increasing the limit depth of the clamping limit strip inserted into the limit groove. Compared with the traditional bolt fixation, it does not require complex tightening operations and can quickly achieve the positioning of the heating rod in the horizontal direction. At the same time, the cooperation of the conical groove and the alignment pin provides precise guidance for the vertical installation of the silicon carbide heating rod. The operator only needs to insert the sliding plate into the fixed groove, and with the assistance of the docking of the conical groove and the alignment pin, the positioning of the silicon carbide heating rod in the vertical direction can be easily completed, greatly shortening the installation time.

[0030] Also, during the maintenance stage, the above design is also convenient for quick disassembly and replacement. When replacement is needed, at normal ambient temperature, only by pulling the sliding plate backward, the clamping limit strip will move out of the limit groove on the sliding plate, and the old silicon carbide heating rod can be easily removed indirectly. The installation process is also simple, improving the efficiency of equipment maintenance and reducing the downtime caused by equipment maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] Next, the present invention will be further described in detail according to the drawings and embodiments.

[0046] Embodiment: Please refer to Figures 1 to 5 , Figure 7 , Figure 9 , Figure 10As shown in the figure: To solve the problems mentioned in the technical solution, the embodiment of the present application provides an anti-corrosion titanium anode coating preparation device, including: a segmented temperature-controlled sintering furnace 1, a closed door panel 2, a furnace chamber 3, and a substrate support 4. The closed door panel 2 is arranged on the segmented temperature-controlled sintering furnace 1 through a rotating shaft. The furnace chamber 3 is fixedly connected inside the segmented temperature-controlled sintering furnace 1, and the substrate support 4 is fixedly connected inside the furnace chamber 3. It also includes: a multi-dimensional dynamic balance anti-interference and stability component 5, a temperature processing redundancy guarantee component 6. The temperature processing redundancy guarantee component 6 is arranged inside the multi-dimensional dynamic balance anti-interference and stability component 5; the multi-dimensional dynamic balance anti-interference and stability component 5 is used to maintain the stability of the silicon carbide heating rod 609 during the processes of thermal expansion and contraction, vacuum pumping, and introduction of protective gas; the multi-dimensional dynamic balance anti-interference and stability component 5 includes an attached arc body 501 fixedly attached to the inner wall of the furnace chamber 3. The tail end of the attached arc body 501 is fixedly connected to a connecting member 502. The bottom end of the connecting member 502 is fixedly connected to a fixed groove body 503. A moving plate 504 is slidably connected inside the attached arc body 501. The end face of the moving plate 504 is fixedly connected to a connecting rod 505. One end of the connecting rod 505 far from the moving plate 504 is fixedly connected to a triangular block 506. A spring A 507 is fixedly connected to the inner wall of the attached arc body 501. The bottom end of the spring A 507 is fixedly connected to a clamping and restricting strip 508. A sliding plate 509 is slidably connected inside the fixed groove body 503. An auxiliary groove is opened at the bottom end of the fixed groove body 503. The length of this auxiliary groove is less than the total length of the fixed groove body 503. A restricting groove 510 is opened at the outer end of the sliding plate 509. Conical grooves 511 are symmetrically opened at the tail end of the restricting groove 510. A positioning pin 512 is fixedly connected to the fixed groove body 503.

[0047] Among them: The multi-dimensional dynamic balance anti-interference and stability component 5 is used to maintain the stability of the silicon carbide heating rod 609 during the processes of thermal expansion and contraction, vacuum pumping, and introduction of protective gas.

[0048] An auxiliary groove is opened at the bottom end of the fixed groove body 503. This auxiliary groove is used for the stable linear sliding of the ceramic insulating part 607. The length of this auxiliary groove is less than the length of the fixed groove body 503, so as to assist the sliding plate 509 to move inside the fixed groove body 503 for air pushing actions.

[0049] Before high-temperature preparation, after installation, the depth of insertion of the clamping and restricting strip 508 into the restricting groove 510 is relatively shallow. When carrying out the high-temperature preparation of the titanium anode, the gas expansion inside the attached arc body 501 will cause the clamping and restricting strip 508 to perform a deeper insertion and restriction work.

[0050] A heat insulation board can be inserted into the gap between the attached arc body 501 and the fixed groove body 503.

[0051] The clamping and restricting strip 508 is slidably adapted to the restricting groove 510; the conical groove 511 is inserted and adapted to the positioning pin 512.

[0052] Further embodiments: Please refer to Figure 4 and Figures 6 to 9 as shown: The temperature processing redundancy protection component 6 is used to maintain the stability of the components of the device at high temperatures. The temperature processing redundancy protection component 6 includes a redundancy adjustment plate 601 slidably connected inside the attached arc body 501. A spring B602 is fixedly connected to the redundancy adjustment plate 601. A sleeve 603 is fixedly connected to the redundancy adjustment plate 601. A sliding piece 604 is slidably connected inside the sleeve 603. Through holes 605 are equidistantly arranged on the sliding piece 604. A plugging column 606 is fixedly connected to the sliding piece 604. One end of the plugging column 606 away from the sliding piece 604 is fixedly connected to the moving plate 504. A ceramic insulating part 607 is fixedly connected to the bottom surface of the sliding plate 509. A ceramic tube 608 is inserted and fixedly connected inside the ceramic insulating part 607. A silicon carbide heating rod 609 is inserted into the ceramic insulating part 607. A clamping groove is arranged on the ceramic tube 608. A shape memory alloy clamping strip 610 is clamped in the clamping groove of the ceramic tube 608.

[0053] Among them: The temperature processing redundancy protection component 6 is used to maintain the stability of the components of the device at high temperatures.

[0054] The sleeve 603 is provided with a metal fluid.

[0055] The shape memory alloy clamping strip 610 can stably limit the silicon carbide heating rod 609 at high temperatures and will not cause loosening of the clamping fixation due to temperature changes.

[0056] Further embodiments: A method for preparing an anti-corrosion titanium anode coating, comprising the following steps: preliminary preparation, installation of temperature control components, heating stage, heat preservation stage, cooling stage, taking out the workpiece, and detection and treatment.

[0057] The preliminary preparation step includes: placing the titanium anode substrate that has been pretreated and coated with a coating on the high-temperature-resistant substrate support 4, checking whether the furnace chamber 3 is clean and free of debris residue, connecting the protective gas gas source to ensure normal gas supply, and setting the parameters of the temperature control system, including the temperature, heating rate, heat preservation time, and cooling rate of each stage.

[0058] The installation step of the temperature control components includes: sliding the sliding plate 509 with the silicon carbide heating rod 609 into the fixed groove body 503. Under the connection of the attached arc body 501, the connecting part 502, and the fixed groove body 503, the gas inside indirectly assists the clamping and restricting strip 508 to perform the clamping work on the sliding plate 509 with the silicon carbide heating rod 609 under the setting of the restricting groove 510.

[0059] The steps of the heating-up stage include: starting the segmented temperature-controlled sintering furnace 1, the temperature control system controlling the silicon carbide heating rod 609 to start heating, slowly raising the temperature of the furnace chamber 3 at a preset heating rate. During this process, volatile substances such as moisture and organic matter in the coating gradually volatilize and are discharged; the heating rate is controlled at 1 to 5 °C / min.

[0060] The steps of the heat preservation stage include: when the temperature of the furnace chamber 3 reaches the preset heat preservation temperature, maintaining this temperature for a period of time. During this process, atoms inside the coating undergo diffusion and recrystallization changes; the heat preservation time depends on the composition and thickness of the coating.

[0061] The steps of the cooling-down stage include: after the heat preservation ends, the temperature control system controls the silicon carbide heating rod 609 to stop heating and start cooling, and controls the cooling rate; in the high-temperature section, the cooling rate is controlled at 5 to 10 °C / min; in the low-temperature section, the cooling rate is appropriately increased, or natural cooling is adopted.

[0062] Taking out the workpiece and the inspection and treatment steps include: when the temperature inside the segmented temperature-controlled sintering furnace 1 begins to drop to a safe temperature, the operator takes protective measures, wears high-temperature protective gloves and goggles, opens the closed door panel 2, takes out the sintered titanium anode substrate from the substrate support 4 inside the furnace chamber 3, and after taking it out, places the workpiece on a special cooling table for natural cooling or, according to the requirements of subsequent inspection and treatment processes, after further cooling treatment, conducts subsequent inspection or processing operations such as coating thickness measurement, composition analysis, and bonding strength testing.

[0063] The working principle of all the contents in the above embodiments is as follows: The following is the working process of the multi-dimensional dynamic balance anti-interference and stabilization component 5: When in use, first slide the sliding plate 509 into the fixed groove 503. During this process, the sliding plate 509 will perform a linear plugging motion with the assistance of the auxiliary groove opened at the bottom of the fixed groove 503 and the ceramic insulator 607. As known, an auxiliary groove is opened at the bottom end of the fixed groove 503, which is used for the stable linear sliding of the ceramic insulator 607. The length of this auxiliary groove is less than the length of the fixed groove 503, so as to assist the sliding plate 509 to move inside the fixed groove 503 to perform a gas-pushing action. For reference, see Appendix Figure 7 and Appendix Figure 10, as the sliding plate 509 is pushed, the gas will gradually transfer from the fixed groove body 503 and the connecting member 502 to the inner cavity of the attached arc body 501; further, as the gas transfers, the moving plate 504 will, with the assistance of the temperature processing redundancy guarantee component 6, drive the triangular block 506 through the connecting rod 505 to move towards the clamping limit strip 508. During this process, the spring B602 in the temperature processing redundancy guarantee component 6 will be compressed to a certain extent. Further, since it is known that the contact surface between the triangular block 506 and the clamping limit strip 508 is an inclined surface and the triangular block 506 is in a linear motion state, as the triangular block 506 moves, the clamping limit strip 508 will move during the movement of the triangular block 506, and at this time the spring A507 will be stretched. Further, as the sliding plate 509 is gradually inserted and with the participation of the gas, the clamping limit strip 508 will gradually move and finally be inserted into the limit groove 510 opened on the sliding plate 509, and at this time the plugging and fixing work is initially stable.

[0064] Further, since it is known that, after installation and without high-temperature preparation, the depth of the clamping limit strip 508 inserted into the limit groove 510 is relatively shallow. Further, when the titanium anode is prepared at high temperature, the gas expansion in the attached arc body 501 will prompt the clamping limit strip 508 to perform a deeper plugging and limiting work, so that the plugging and fixing work is further stabilized.

[0065] It should be noted that during the plugging and fixing process, the conical groove 511 and the alignment pin 512 can be used to stabilize the sliding and fixing work of the sliding plate 509.

[0066] Further; through the design of the multi-dimensional dynamic balance anti-interference and stability component 5, the influence of thermal expansion and contraction on the device can be effectively overcome, and it has an adaptive adjustment function; that is, in the traditional bolt fixing method, when the temperature changes, due to the different thermal expansion coefficients of the connecting piece and the heating rod, stress concentration is likely to occur, resulting in loosening; while the multi-dimensional dynamic balance anti-interference and stability component 5 uses gas-assisted design and can indirectly and dynamically adjust the limiting stability of the silicon carbide heating rod 609 according to the temperature change; when the temperature rises, the gas in the attached arc body 501 expands and the pressure increases, indirectly causing the limiting component, the clamping limit strip 508, to move adaptively and cooperate with the limit groove 510, which not only indirectly maintains the stability of the silicon carbide heating rod 609, but also avoids the abnormal movement of the components caused by temperature factors to the stable silicon carbide heating rod 609; when the temperature drops, the gas contracts, and the limiting component adjusts inward accordingly, that is, it contracts towards the inside of the attached arc body 501, but it will always cooperate with the limit groove 510 on the sliding plate 509 to maintain the limit, effectively reducing the problems of fixing stability caused by thermal expansion and contraction, thereby indirectly causing the displacement of the silicon carbide heating rod 609 and ensuring the uniform distribution of the temperature in the furnace chamber 3.

[0067] Flexible buffering: This component uses the cooperation of triangular blocks 506, clamping and restricting strip plates 508 and gas. During the process of thermal expansion and contraction, the triangular blocks 506 can play a buffering role to a certain extent by pushing the clamping and restricting strip plates 508 through their inclined surfaces, absorbing the stress generated by temperature changes. In contrast, traditional bolt fixation lacks this flexible buffering mechanism and is prone to loosening under stress accumulation, indirectly causing the position of the silicon carbide heating rod 609 to shift, resulting in uneven temperature and affecting the quality of the titanium anode coating.

[0068] Furthermore, by adopting the clamping and restricting strip plate 508, the restricting groove 510, the tapered groove 511, and the alignment pin 512, the stability during the vacuum pumping stage can be enhanced under various dimensional working conditions; that is, during the vacuum pumping process, the rapid change in air pressure in the furnace chamber 3 will cause vibrations. The cooperation between the clamping and restricting strip plate 508 and the restricting groove 510 plays a key role. The clamping and restricting strip plate 508 is tightly embedded in the restricting groove 510 of the sliding plate 509, and the precise cooperation between the two forms multi-directional constraints; when vibrations occur, the clamping and restricting strip plate 508 can effectively block the displacement of the silicon carbide heating rod 609 in the horizontal direction in the restricting groove 510, suppressing its swaying in the horizontal and vertical directions; at the same time, the combination of the tapered groove 511 and the alignment pin 512 further strengthens this stability. The alignment pin 512 is accurately inserted into the tapered groove 511. Utilizing the characteristics of the tapered structure, it automatically adjusts and maintains the central positioning of the sliding plate 509 during vibrations. Even when subjected to vibration impact forces from different directions, the close contact and self-adaptive adjustment ability between the tapered groove 511 and the alignment pin 512 can ensure that the silicon carbide heating rod 609 connected to the sliding plate 509 remains stable in the vertical direction, effectively guaranteeing the stable operation of the heating system.

[0069] Guarantee the uniform temperature connection between processes and improve the coating quality: By reducing the displacement of the silicon carbide heating rod 609 during different working stages, the stable position of the silicon carbide heating rod 609 ensures uniform heat distribution in the furnace chamber 3, avoiding local overheating or overcooling phenomena caused by the displacement of the silicon carbide heating rod 609 during different process stages, and stabilizing the temperature connection between processes; it helps the elements in the coating to fully diffuse and react, enhancing the bonding force between the coating and the substrate and improving the corrosion resistance of the coating.

[0070] Furthermore, by using the clamping limit strip 508, the limit groove 510, the conical groove 511, the alignment pin 512, and the cooperation of the gas, in terms of installation, it can bring benefits that are different from the existing installation for the overall installation; improve the convenience of installation and maintenance, that is, during the installation process of the silicon carbide heating rod 609, the installer only needs to push the sliding plate 509 with the silicon carbide heating rod 609, and the sliding plate 509 can push the gas inside the attached arc body 501, the connecting member 502, and the fixed groove body 503 to move, thereby indirectly causing the clamping limit strip 508 to cooperate with the limit groove 510 to limit and fix the sliding plate 509 with the silicon carbide heating rod 609. During this process, the design of the conical groove 511 and the alignment pin 512 can assist in more precise installation. The above-mentioned clamping method of the clamping limit strip 508 and the limit groove 510, and during operation, in cooperation with gas expansion, when the clamping depth of the clamping limit strip 508 inserted into the limit groove 510 is increased again, compared with the traditional bolt fixation, there is no need for complex tightening operations, and the positioning of the heating rod in the horizontal direction can be quickly achieved; at the same time, the cooperation of the conical groove 511 and the alignment pin 512 provides an accurate guide for the vertical installation of the silicon carbide heating rod 609. The operator only needs to insert the sliding plate 509 into the fixed groove body 503, and with the assistance of the docking of the conical groove 511 and the alignment pin 512, the positioning of the silicon carbide heating rod 609 in the vertical direction can be easily completed, greatly shortening the installation time.

[0071] At the same time, during the maintenance stage, the above design is also convenient for quick disassembly and replacement; when replacement is needed, at the normal external temperature, only need to pull the sliding plate 509 backward, and the clamping limit strip 508 will move out of the limit groove 510 on the sliding plate 509, and then the old silicon carbide heating rod 609 can be easily removed indirectly. The installation process is also simple to operate, improving the efficiency of equipment maintenance and reducing the downtime caused by equipment maintenance.

[0072] Please refer to the above working process Figures 1 to 5 、 Figure 7 、 Figure 9 、 Figure 10 。

[0073] The following is the working process of the temperature processing redundancy guarantee component 6: Furthermore, when carrying out the work of high-temperature preparation of titanium anodes, the gas expansion in the attached arc body 501 will prompt the clamping limit strip 508 to perform a deeper plugging and limiting operation. It should be noted that during this process, the redundancy control board 601 in the temperature processing redundancy guarantee component 6 will be first pushed by the gas, but due to the limited passive compression amount of the spring B602, the operation of the plugging depth of the above-mentioned clamping limit strip 508 can be effectively guaranteed.

[0074] Furthermore, as the work progresses, high temperature will gradually affect the position of the moving plate 504. That is, the expanded gas will push the moving plate 504. However, due to the existence of spring B 602 and the buffer composed of the sleeve 603, the sliding piece 604, the through hole 605, and the insertion post 606, the redundant variable that promotes the movement of the moving plate 504 can be effectively weakened, reducing the possibility that the forcedly moved moving plate 504 drives the triangular block 506 through the connecting rod 505 to contact and adhere to the inner wall of the attaching arc body 501, resulting in component damage.

[0075] Furthermore, through the design of the temperature treatment redundancy guarantee component 6, it can provide strong support in many aspects for the stable operation of the device in a high-temperature environment, which is of great significance for improving the overall performance of the device, extending the service life, and ensuring the continuity of production and product quality. It can effectively improve the stability of components and prevent non-operational movement of the main components. That is, high temperature may cause thermal stress in the main components of the device, and the material properties of each component will undergo volume changes. The temperature treatment redundancy guarantee component 6 can regulate the components in an active or passive manner to ensure that each component undergoes displacement or deformation in a non-operational state within the corresponding temperature range, thereby triggering non-operational movement, such as displacement and vibration. This component can suppress these movements through buffering and restraint methods, ensuring that each component can still maintain the correct relative position and working attitude at high temperature and maintaining the functional integrity of the device.

[0076] Guarantee the functional reliability of the device: During the preparation process of the titanium anode coating, the accuracy of temperature control and the stability of components are crucial for the coating quality. The temperature treatment redundancy guarantee component 6 ensures the stable operation of the device at high temperature, avoids the deviation of component position fluctuations caused by temperature problems, thereby indirectly ensuring the consistency and performance of the coating and effectively reducing the scrap rate.

[0077] Enhance system safety and improve production continuity: If component damage or function failure occurs in a high-temperature device, there is a risk of triggering safety accidents. This component effectively reduces these risks by ensuring component stability and preventing function failure, guaranteeing the safety of operators' lives and the production environment. At the same time, reducing component damage and function failure means shortening the equipment downtime, improving production efficiency, enabling the device to operate stably for a long time, reducing production interruptions caused by equipment failures, and effectively improving the production efficiency and economic benefits of the enterprise.
