Description

Technical Field

[0001] This invention relates to the field of stove manufacturing technology, and more specifically, to a refractory coating equipment for ceramic ovens. Background Technology

[0002] Ceramic ovens are widely used in commercial and high-end home applications due to their excellent heat retention and unique cooking effects. Compared with other ovens, ceramic ovens have advantages such as good heat insulation, even heat distribution, efficient heat utilization, ability to lock in moisture in food, unique flavor, wide range of baking applications, high safety performance, low risk of open flame, non-toxic materials, easy cleaning and maintenance, resistance to staining and rust, and beautiful and diverse appearance with strong decorative appeal.

[0003] The refractory coating on the inner wall of a ceramic oven (i.e., the inner surface of the furnace chamber) is an essential component of the oven. The refractory coating plays a core role in protecting the oven body, improving thermal efficiency, and improving combustion. Currently, the automatic application of refractory coatings mostly uses spraying machines or paint spray guns commonly used in industries such as construction. Although these devices can increase the coating speed compared to manual operation, when faced with high-viscosity, high-solids refractory slurries, the nozzles of general spraying machines or paint spray guns are easily clogged by particles in the slurry, leading to work interruptions and requiring frequent cleaning. Moreover, the surface of the sprayed coating is rough and loose, without compaction and smoothing, resulting in poor adhesion. This affects the quality of the ceramic oven, necessitating manual smoothing of the coating in the later stages. Summary of the Invention

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] like Figures 1-14 As shown, a ceramic oven refractory coating application device includes: The rotary coating mechanism 1 is used to horizontally fix the furnace body 2. The rotary coating mechanism 1 can automatically coat the refractory slurry onto the inner wall of the furnace body 2 with radial pressure. The flattening and shaping mechanism 3 is installed on the rotary coating mechanism 1. The flattening and shaping mechanism 3 can compact and flatten the fresh coating, and can heat-blow the fresh coating to promote the curing of the fresh coating. Before applying the refractory slurry, the rotary coating mechanism 1 cleans the inner wall of the furnace body 2. By continuously rotating the furnace body 2 using the rotary coating mechanism 1, the refractory slurry is directly extended and applied to the inner wall of the furnace body 2 using shearing action. This ensures smooth material discharge, effectively preventing slurry blockage and operation interruptions, and avoiding frequent cleaning. Furthermore, the rotary coating mechanism 1 can apply radial pressure while coating, effectively ensuring the density of the coating and allowing it to better bond with the inner wall of the furnace body 2, thus ensuring the coating quality. The flattening and shaping mechanism then... Following closely behind the rotary coating mechanism 1, the 3 mechanism can compact and flatten the fresh coating again, further enhancing the bond between the coating and the inner wall of the furnace body 2, ensuring good adhesion of the coating, and thus guaranteeing the quality of the produced ceramic ovens. Under the action of the rotary coating mechanism 1 and the flattening and shaping mechanism 3, it also has the function of wetting the inner wall of the furnace body 2 before coating and performing timely preliminary shaping treatment on the fresh coating, thereby further ensuring that the coating can have sufficient bonding force with the inner wall of the furnace body 2 and reducing the generation of cracks on the coating, thus comprehensively improving the coating quality.

[0020] Optionally, the rotary coating mechanism 1 includes: Main pier 11, which serves as a foundation positioning component; Main shaft 12 is rotatably mounted on main body pier 11; Motor 13 is connected to main shaft 12 via a coupling; Connecting claw 14 is mounted on the main shaft 12; End panel 15, which is connected to connecting claw 14; Lower support 16 is fixedly installed on end panel 15; The upper clamp 17 is vertically and movably mounted on the end panel 15 and located directly above the lower support 16; Manual screw 18 is screwed on end panel 15, and the end of manual screw 18 is rotatably connected to the back of upper clamp 17. When the furnace body 2 is placed horizontally on lower support 16, the upper clamp 17 can be gradually pushed towards the furnace body 2 when the manual screw 18 is rotated downward. Base plate 19, base plate 19 is connected to main body pier 11; Linear module 191 is mounted on base plate 19. Linear module 191 can be a linear motor or ball screw, etc., as long as it can perform linear reciprocating motion. Support 192 is mounted on linear module 191; The cantilever arm 193 is mounted on the top of the support 192 and faces the end panel 15. When the linear module 191 is activated, it can drive the cantilever arm 193 to move closer to the end panel 15. The discharge cylinder 194 is rotatably installed at one end of the cantilever arm 193. The discharge cylinder 194 is hollow and has dense elongated outlets on its periphery. Bearing 195 is installed on the other end of the discharge cylinder 194; The conveying pipe 196 is installed on the inner ring of the bearing 195 and inserted into the discharge cylinder 194; Material box 197 is installed on the top of support 192. Material box 197 is provided with a feeding port. Material conveying pipe 196 passes through cantilever arm 193 and connects to material box 197. Piston plate 198 is fitted inside the material box 197; The first electric push rod 199 is installed on the side of the material box 197. The output end of the first electric push rod 199 extends into the material box 197 and connects to the back of the piston plate 198. When applying the refractory coating, the furnace body 2 is placed horizontally on the lower support 16 with the opening facing outward. Then, the manual screw 18 is rotated downward to push the upper clamp 17 gradually downward along the end panel 15 until the upper clamp 17 presses against the furnace body 2. Part 17 and lower support 16 clamp and fix the furnace body 2. Then, the linear module 191 is activated to send the cantilever arm 193 into the furnace body 2 until the discharge cylinder 194 is sent to the deepest part of the furnace body 2, so that the discharge cylinder 194 contacts the inner wall of the furnace body 2. Then, the motor 13 is activated to directly drive the main shaft 12, and through the connecting claw 14, it drives the end panel 15, thereby driving the furnace body 2 to rotate at a constant speed. At the same time, the first electric push rod 199 is activated to move the piston plate 198. The refractory slurry in the hopper 197 is pushed forward, causing it to enter the discharge cylinder 194 through the conveying pipe 196. Finally, the refractory slurry emerges from the elongated outlet on the side of the discharge cylinder 194. The discharge cylinder 194 is also rotated by the friction with the furnace body 2. At the same time, the linear module 191 is activated, pulling the cantilever arm 193 and the discharge cylinder 194 backward at a uniform speed. Thus, through the coordination of multiple aspects, the rotating discharge... The cylinder 194 directly extends and applies the refractory slurry to the inner wall of the furnace body 2, automatically completing the coating of the refractory coating and ensuring that the inner wall of the furnace body 2 is evenly coated with the refractory slurry without any omissions. During the coating process, the first electric push rod 199 pushes the piston plate 198 to squeeze the refractory slurry, forcing it to emerge outward from the elongated outlet on the side of the discharge cylinder 194. The discharge is smooth, which can effectively prevent the slurry blockage that could cause the operation to be interrupted and avoid the need for frequent cleaning.

[0021] Optionally, support 192 includes: Sleeve 1921, sleeve 1921 is installed on linear module 191; Support column 1922 is slidably inserted into sleeve 1921, and cantilever arm 193 and hopper 197 are located on support column 1922; The second electric push rod 1923 is vertically mounted on the linear module 191, and its output end is connected to the support column 1922. When the discharge cylinder 194 is sent to the deepest part of the furnace body 2, the second electric push rod 1923 is immediately activated to pull down the support column 1922. This allows the discharge cylinder 194 to be attached to the inner wall of the furnace body 2 through the cantilever arm 193. This enables the discharge cylinder 194 to apply a certain radial pressure to the inner wall of the furnace body 2 during coating. Applying radial pressure while coating effectively ensures the density of the coating and prevents the coating from being too loose, allowing it to better bond with the inner wall of the furnace body 2 and ensuring the coating quality. In addition, the second electric push rod 1923 can also be used to control the distance between the discharge cylinder 194 and the inner wall of the furnace body 2, thereby coating different thicknesses to meet different production requirements.

[0022] Optionally, the flattening and shaping mechanism 3 includes: Swing cylinder 31, swing cylinder 31 is mounted on cantilever arm 193; The swing arm 32 is mounted on the output shaft of the swing cylinder 31; The pressure contact element 33 is connected to the end of the swing arm 32 and is located next to the discharge cylinder 194. During coating, according to the rotation direction of the furnace body 2, i.e., the coating direction, the pressure contact element 33 is located behind the discharge cylinder 194. When the discharge cylinder 194 is attached to the inner wall of the furnace body 2 and the coating is about to begin, the swing cylinder 31 is activated, and the swing arm 32 swings the pressure contact element 33 toward the inner wall of the furnace body 2. According to the thickness of the coating to be coated, the pressure contact element 33 is swung to a height that can press the coated coating and hold it there. Then the coating begins. In this way, the pressure contact element 33 can follow closely behind the discharge cylinder 194. Based on the coating on the discharge cylinder 194, the fresh coating on the discharge cylinder 194 is compacted and smoothed again to further enhance the bonding strength between the coating and the inner wall of the furnace body 2, ensuring that the coating has good adhesion and uniform coating thickness, thereby ensuring the quality of the ceramic oven produced. In addition, after the coating is completed, the coating action can be performed again, but without discharging refractory slurry. During this process, the swing cylinder 31 is repeatedly started, and the pressure contact part 33 is used to gently tap the coating surface to expel the air bubbles hidden in the coating, ensuring that the coating is dense and free of voids, further ensuring the quality of the coating.

[0023] Optionally, the flattening and shaping mechanism 3 also includes: A strip-shaped air outlet 34 is installed at the top edge of the pressure contact member 33; Connector 35 connects one end to the strip-shaped air outlet 34 and the other end to the air outlet of the external hot air dryer. After the pressure contact 33 is swung properly, the strip-shaped air outlet 34 is positioned at an angle to the inner wall of the furnace body 2. When coating begins, the external hot air dryer is started, and the dry hot air generated by it is guided into the strip-shaped air outlet 34 through connector 35 and discharged from the strip-shaped air outlet 34. This dry hot air is blown onto the freshly coated coating, drying the coating to a certain extent, thereby achieving the initial shaping treatment of the fresh coating. This greatly shortens the natural drying and shaping process of the coating, effectively preventing cracks from forming due to excessive natural shaping during this process, effectively reducing the occurrence of cracks, improving coating quality, and shortening the production cycle time to improve efficiency.

[0024] Optionally, the front half of the internal channel of the strip-shaped air outlet 34 is flatter than the rear half, that is, the part of the internal channel of the strip-shaped air outlet 34 near the connector 35 is thicker. In this way, when the connector 35 sends dry hot air into the strip-shaped air outlet 34, because the rear half of the strip-shaped air outlet 34 is thick and the front half is flat, the airflow cannot be blown out quickly. The excess airflow that cannot be blown out will diffuse and accumulate, so that dry hot air can be blown out from the entire outlet of the strip-shaped air outlet 34, ensuring the coverage area of ​​the coating by the dry hot air, ensuring uniform and complete preliminary shaping treatment of the coating, and preventing any missed areas.

[0025] Optionally, the pressure contact element 33 has an arc surface, with the arc surface facing downwards. The inner wall of the furnace body 2 is arc-shaped and the furnace body 2 rotates during the coating process. Therefore, using the arc surface of the pressure contact element 33 to flatten the coating can better contact the coating, thereby ensuring the effect of compaction and smoothing. At the same time, it ensures the smoothness of the flattening process and effectively prevents the pressure contact element 33 from colliding with the inner wall of the furnace body 2, ensuring safety.

[0026] Optionally, the rotary coating mechanism 1 further includes: Water storage box 4 is connected to the side of the cantilever arm 193; A cross-shaped silicone valve 5 is installed at the bottom of the water storage box 4. The cross-shaped silicone valve 5 is used to seal the water storage box 4. Spring 6, one end of spring 6 is installed at both ends of the bottom surface of water storage box 4; The fixed back strip 7 is connected to the other end of the spring 6. Sponge strip 8 is installed on the fixed back strip 7. The sponge strip 8 is located next to the discharge cylinder 194 and its height is lower than that of the discharge cylinder 194. Several short tubes 9 are inserted into the fixed backing strip 7 and then into the sponge strip 8. The tops of the short tubes 9 are rounded, and each short tube 9 faces upwards towards a number of cross-shaped silicone valves 5. According to the rotation direction of the furnace body 2, i.e., the coating direction, the sponge strip 8 is located in front of the discharge cylinder 194. During the process of attaching the discharge cylinder 194 to the inner wall of the furnace body 2, because the height of the sponge strip 8 is lower than the discharge cylinder 194, the sponge strip 8 will first contact the inner wall of the furnace body 2. The sponge strip 8 is compressed, thus pushing the fixed backing strip 7 backwards. The fixed backing strip 7 compresses the spring 6. During the movement, the short tubes 9 push open the cross-shaped silicone valves 5 and insert them into the water storage box 4. The short tubes 9 then draw water from the water storage box 4 onto the sponge strip 8, wetting it. The sponge strip 8 moves with the furnace body... The rotation of cylinder 2 cleans the inner wall of furnace body 2 before discharge cylinder 194, removing any stains or dust that may be present on the inner wall of furnace body 2, ensuring the cleanliness of the inner wall of furnace body 2. This fundamentally ensures the adhesion between the coating and the inner wall of furnace body 2. At the same time, the damp sponge strip 8 moistens the inner wall of furnace body 2 to prevent the ceramic inner wall of furnace body 2 from becoming too dry. If furnace body 2 is too dry, it will quickly absorb moisture from the coating, causing the coating to lose water and become brittle before it is fully leveled and cured, thus reducing the adhesion strength with furnace body 2. This ensures that discharge cylinder 194 applies refractory slurry to the relatively moist furnace body 2, ensuring that the slurry is evenly spread, allowing the coating to penetrate and adhere better, ensuring that the coating is firm, durable, and effectively performs its heat insulation and protection functions, and comprehensively improving the coating quality.

[0027] Optionally, a telescopic sleeve 10 is provided between the water storage box 4 and the fixed back strip 7. The telescopic sleeve 10 covers the spring 6 and protects the spring 6 by means of the telescopic sleeve 10, preventing the spring 6 from deforming and causing the fixed back strip 7 to be unable to move in a straight line, preventing the short tube 9 from being smoothly inserted into the cross silicone valve 5, and ensuring that the short tube 9 can be smoothly pulled out by the rebound.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
