Description

Technical Field

[0001] This invention relates to the field of ceramic body production technology, and more specifically to a ceramic body coating heating system. Background Technology

[0002] In the manufacturing process of ceramic insulators, chemical vapor deposition is the core technology for forming high-quality functional films. This process typically requires tin tetrachloride as a precursor, which is then deposited on the ceramic surface through a pyrolysis reaction at high temperature to form a dense and uniform tin dioxide film.

[0003] To meet the needs of industrial production, existing technologies often employ a hanging cage to support multiple ceramic bodies and send them into a high-temperature furnace for continuous or semi-continuous heat treatment.

[0004] However, existing sidewall spraying processes have significant technical limitations when processing ceramic bodies with complex geometries (such as cylinders) or requiring all-around coating. Because the spraying assembly is typically fixed at a specific location on the furnace sidewall, the atomized chemical solution, limited by its linear propagation characteristics, often only covers the side of the ceramic body facing the spray nozzle. For cylindrical ceramic bodies, the side facing away from the spray nozzle is prone to forming a "shadow zone," resulting in missing or severely insufficient film thickness.

[0005] The existing production process is forced to adopt a cumbersome "double-furnace entry" process, which involves spraying a coating onto one side of the ceramic body, then removing the cage from the high-temperature furnace, allowing it to cool, or flipping and adjusting the ceramic body using a robotic arm, before moving it back into the high-temperature zone of the furnace for a second spraying. This segmented processing mode has significant drawbacks: First, frequent furnace entry and exit operations disrupt the continuity of the heat treatment process, significantly lengthening the production cycle and severely restricting capacity; second, it is difficult to accurately reproduce the temperature field environment during the first furnace entry process when the ceramic body is removed and re-entered, and temperature fluctuations can easily lead to differences in the crystal quality, adhesion, and photoelectric properties of the two deposited films, forming obvious "joints" or performance gaps; finally, repeated heating and cooling cycles also greatly increase energy consumption and equipment wear. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide a ceramic body coating heating system that solves the problem that the ceramic body coating process in the prior art requires multiple furnace entry and exit for surface changes, resulting in long processing time and uneven film quality.

[0020] To address the technical problem in existing ceramic coating technologies that require multiple furnace passes for surface changes, resulting in long processing times and uneven film quality, this invention provides a ceramic coating heating system. A second spray element 31 sprays a reaction liquid onto the outer side of the installation area from the outside of the furnace body 1. Simultaneously, a first spray element 22 sprays the reaction liquid from the inside of the furnace body 1 towards the inner side of the installation area. This combined internal and external three-dimensional spraying method allows the reaction liquid to act on the ceramic surface from different directions simultaneously, ensuring that all aspects of the ceramic are uniformly and completely covered.

[0021] Please see Figures 1-9 , Figures 1-9A ceramic body coating heating system provided in one embodiment of the present invention includes a furnace body 1, a conveying mechanism 2, and a spraying mechanism 3.

[0022] In one embodiment, the furnace body 1 is constructed as a high-temperature furnace body, and its interior is lined with a layer of refractory bricks. It should be noted that this application does not strictly limit the specific physical structure of the furnace body, and it can adopt any applicable structure known to those skilled in the art.

[0023] Specifically, two sliding wheels are provided on opposite sides of the bottom of the movable part 21, and two guide rails are installed at intervals on one side of the furnace body. The sliding wheels on opposite sides of the movable part slide in cooperation with the corresponding guide rails. It can be understood that when the movable part 21 moves along the length of the guide rail, it can drive the placement part 23 to enter and exit the cavity 1a through the opening.

[0024] Based on the above scheme, the movable part 21 is provided with a heat insulation cotton layer, and a cover plate is provided on one side of the heat insulation cotton layer. When the placement part 23 is moved into the cavity 1a, the heat insulation cotton layer seals the opening, and the cover plate abuts against the outer wall of the furnace body.

[0028] In one embodiment, the placement member 23 includes a frame 231, multiple support portions 232, and a locking portion 233. The frame 231 is mounted on a rotating shaft 221. The frame 231 has multiple mounting areas along its circumference, and each mounting area has a limiting channel 231a with an insertion end. The support portions 232 are configured to support multiple ceramic bodies in parallel and at intervals, and the support portions 232 can move into or out of the limiting channel 231a through the insertion. The locking portion 233 is configured to be detachably connected to the frame 231 to close or open the multiple insertions. Specifically, the placement member 23 is also made of a high-temperature resistant material.

[0029] It is understood that the frame 231 includes four fixed rods 2311 and a cross-shaped connecting plate 2312. The cross-shaped connecting plate is fixedly connected to the rotating shaft and to the four fixed rods. A sliding groove is provided on the side of the two fixed rods that are close to each other, and a limiting channel 231a is formed between the two sliding grooves for the bearing part 232 to pass through.

[0030] In one embodiment, the support portion 232 includes a square frame, which includes two horizontal bars and two vertical bars connected between the two horizontal bars. One horizontal bar is provided with a plurality of through holes 232a at intervals, and the other horizontal bar is provided with a plurality of clearance grooves 232b at intervals, and each clearance groove 232b is coaxially aligned with each through hole 232a.

[0031] Specifically, the ceramic body is cylindrical in shape. One end of the ceramic body is inserted through the perforation 232a and extends into the relief groove 232b, so that multiple ceramic bodies can be supported in the square frame at intervals and parallel. The square frame can be slidably inserted into the limiting channel 231a from the insertion port at one end of the limiting channel 231a.

[0032] In one embodiment, the locking part 233 consists of a baffle 2331 and multiple locking bolts 2332. The baffle 2331 has multiple connecting holes, and the locking bolts 2332 pass through the connecting holes and are screwed into the threaded holes on the frame 231 to fix the baffle 2331 to the frame 231. Specifically, each of the four fixing rods has a threaded hole at its end. The baffle 2331 is a square baffle, and the baffle 2331 is connected to the four fixing rods respectively by the four locking bolts 2332, so that the insertion port at one end of the four limiting channels 231a can be closed.

[0033] It should be noted that a rotary joint 211 is fixedly provided on the movable part 21, and the movable end of the rotary joint 211 is connected to the end of the rotating shaft 221 and communicates with the liquid guiding cavity. The fixed end of the rotary joint 211 is connected to the infusion tube 212, and the infusion tube 212 is in fluid communication with the second air supply part 213. The movable part 21 is detachably installed with a second liquid storage container 214, and the liquid distribution tube on the infusion tube 212 extends downward and is inserted into the second liquid storage container 214.

[0034] Specifically, a sleeve is installed on the movable part 21, and the bottom of the second liquid storage container can be inserted into the sleeve from top to bottom.

[0035] In one embodiment, the drive member 24 includes a drive motor, a drive sprocket, a driven sprocket, and a chain. The drive motor is mounted on the moving member 21. The output end of the drive motor is equipped with the drive sprocket. The driven sprocket is fixed on the rotating shaft. The chain is wound between the drive sprocket and the driven sprocket.

[0036] It should be noted that, in one embodiment, the spraying mechanism 3 further includes a moving part 32 and two clamping modules 33. The moving part 32 is installed on one side of the furnace body 1 and has a reciprocating translational end 320. The two clamping modules 33 are installed opposite to each other on the translational end. The clamping module 33 includes a support part 331, a blocking part 332 and a locking bolt 333. The support part 331 is installed on the translational end and has a groove. The locking bolt 333 is screwed to the blocking part 332. The blocking part 332 is connected to the support part 331. The blocking part 332 has a first state and a second state. In the first state, the blocking part 332 opens the groove and forms a bayonet. In the second state, the blocking part 332 closes the groove and forms a locking space. One end of the locking bolt 2332 can extend into the locking space and abut against the second spraying part 31 that passes through the locking space.

[0037] Specifically, the support part 331 is provided with two connecting slots, and the blocking part 332 is provided with connecting protrusions that slide in cooperation with the two connecting slots.

[0038] Specifically, the moving part 32 is not limited to a specific structure. Specifically, the moving part 32 includes a mounting base 321, a driving pulley 322, a driven pulley 323, a conveyor belt 324, and a power source 325. The driving pulley 322 and the driven pulley 323 are rotatably mounted on the mounting base 321, and the conveyor belt 324 is connected between the driving pulley 322 and the driven pulley 323. The power source 323 is mounted on the mounting base 321, and its output end is connected to the driving pulley 322 for transmission. Its translation end 320 is slidably connected to the mounting base 321 and fixedly connected to the conveyor belt 324.

[0039] The power source is a drive motor, which is electrically connected to a controller (programmable PLC). It can be understood that an incremental encoder is installed on the output shaft of the drive motor. The controller controls the drive motor to rotate forward or backward a predetermined number of times, thereby realizing the reciprocating movement of the translation end in a preset direction.

[0040] In this specific embodiment, the spraying mechanism 3 further includes a first liquid storage container 34 and a first air supply component 35; the first liquid storage container 34 is detachably installed on the translation end, and the branch pipe connected to the second spray component 31 extends downward to the bottom of the first liquid storage container 34, wherein the second spray component 31 is connected to the air supply component.

[0041] It should be noted that both the first liquid storage container 34 and the second liquid storage container are liquid storage bottles with the bottle openings open, allowing external airflow to enter the liquid storage bottles through the bottle openings.

[0042] Furthermore, a limiting module 36 is also installed on the translation end and between the two clamping modules 33. The limiting module 36 defines a cavity, and the top of the cavity has an opening. The lower end of the first liquid storage container 34 passes through the opening and is accommodated in the cavity. The outer wall contour of the first liquid storage container 34 is adapted to the inner wall contour of the cavity, and the outer diameter of the first liquid storage container 34 matches the inner diameter of the cavity 1a.

[0043] Understandably, a limiting bolt is also screwed onto the limiting module 36, one end of which can extend into the cavity and abut against the outer wall of the first liquid storage container 34.

[0044] It should be noted that both the first liquid storage container 34 and the second liquid storage container contain tin tetrachloride solution; and both the first air supply component 35 and the second air supply component are air compressors.

[0045] It should be noted that the inner diameter of the second spray element is 1.5-3 times the inner diameter of the branch pipe; preferably, the inner diameter of the second spray element is 2.5 times the inner diameter of the branch pipe; the inner diameter of the infusion tube is 1.5-3 times the inner diameter of the dispensing tube; preferably, the inner diameter of the infusion tube is 2.5 times the inner diameter of the dispensing tube.

[0046] Specifically, the high-pressure airflow flows at high speed within the second spray element. When it passes the connection between the branch pipe and the second spray element, the static pressure at the connection point will decrease significantly due to the extremely high gas velocity, according to Bernoulli's principle, thus creating a local negative pressure zone at the branch pipe opening. At this time, the lower end of the branch pipe is inserted into the bottom of the first liquid storage container. The liquid surface in the first liquid storage container is subjected to normal atmospheric pressure. Since the negative pressure at the branch pipe opening is much smaller than the pressure on the liquid surface in the first liquid storage container, this pressure difference will force the liquid in the first liquid storage container to flow upward along the branch pipe and be "drawn" into the second spray element. After the reaction liquid is drawn into the second spray element, it will mix with the high-speed high-pressure airflow to form a gas-liquid two-phase flow, and finally be carried by the high-pressure airflow and sprayed out through the second spray element.

[0047] The principle by which the second gas supply component transports the reaction liquid in the second liquid storage container to the infusion pipe is the same as the principle by which the first gas supply component 35 transports the reaction liquid in the first liquid storage container to the second spray component, and will not be elaborated further here.

[0048] To better understand this invention, the following is combined with... Figures 1 to 9 The technical solution of the present invention will be described in detail below: The drive motor drives the translation end to reciprocate in a preset direction, which in turn drives the second spray element 31 to reciprocate between the two ends of the strip hole. High-pressure airflow is delivered to the second spray element 31 via the first air supply element 35. Under the action of the air pressure difference, the reaction liquid in the first liquid storage container 34 is drawn into the second spray element 31. The reaction liquid mixes with the gas in the second spray element 31 and is then sprayed out, enabling the spraying of reaction liquid to each installation area one by one, ensuring that the ceramic surface inside the furnace body 1 can receive the reaction liquid evenly. Simultaneously, the second air supply... The component delivers high-pressure gas flow to the infusion pipe. Under the action of the pressure difference, the reaction liquid in the second liquid storage container is drawn into the liquid guiding chamber of the rotating shaft. After the reaction liquid mixes with the gas in the liquid guiding chamber, it is sprayed out through multiple nozzles, which can spray the reaction liquid on the inner side of multiple installation areas at the same time. When the spraying of reaction liquid into the furnace body is stopped, the locking bolt 2332 can be rotated to release the fixing restriction on the second spray component 31. The second spray component 31 can be moved out of the furnace body, and ceramic fiber cotton cloth is inserted into the strip hole to seal the strip hole.

[0049] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
