Description

Technical Field

[0001] This utility model relates to the field of spraying device technology, specifically a spraying device for an anti-oxidation coating on the surface of a silicon carbide rod. Background Technology

[0002] Silicon carbide rods generally refer to rod-shaped components made of silicon carbide (SiC) rods and their composite materials. Due to their high hardness, high temperature resistance, wear resistance, and good thermal conductivity, they are widely used in high-temperature components, abrasives, cutting tools, and corrosion-resistant parts. By spraying an anti-oxidation coating on their surface, they form a dense barrier in high-temperature or corrosive environments to inhibit the reaction between oxygen and the substrate, improve heat oxidation resistance and thermal stability, extend service life, and improve surface properties, thereby enhancing overall performance and reliability.

[0003] Upon investigation, a utility model patent discloses a spraying device for an antioxidant coating (publication number: CN215612477U), which includes a base plate, a fixed plate connected to the top of the base plate, a first motor connected inside the fixed plate, a connecting column connected to one end of the first motor, a conveyor belt connected to the upper surface of the connecting column, a rotating shaft connected to one end of the connecting column, a support plate connected to the top of the base plate on one side of the fixed plate, and a spraying device installed on the top of the support plate.

[0004] While the aforementioned patent allows the spraying device to adjust the density of the anti-oxidation coating by setting a stirring rod and a nozzle, thus avoiding problems such as weak spraying and uneven coloring, and enables automated spraying by setting a conveyor belt and spraying device, thereby improving work efficiency and saving spraying costs, the device is not convenient for spraying the silicon carbide rod completely in one go. It requires manual flipping and re-spraying afterward, which increases the operator's workload and affects work efficiency. At the same time, it is easy to cause uneven spraying, which affects the anti-oxidation effect.

[0005] Therefore, this invention provides a device for spraying an anti-oxidation coating on the surface of a silicon carbide rod to solve the above-mentioned problems. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides a device for spraying an anti-oxidation coating on the surface of a silicon carbide rod, such as... Figures 1-4 As shown, the carbon silicon rod surface anti-oxidation coating spraying device includes a support frame 1, a drive component is fixedly installed on one side of the support frame 1, and mounting frames 2 are fixedly connected to both sides of the support frame 1. A fixing component is fixedly installed on the upper surface of the mounting frame 2, and a spraying component is fixedly installed on the back of the support frame 1. The drive assembly includes a motor 4, one side of which is fixedly mounted on one side of the support frame 1. A rotating plate 5 is fixedly connected to the output end of the motor 4. A first anti-slip pad 6 is fixedly connected to the upper surface of the rotating plate 5. A first protective shell 7 is rotatably connected to the outer surface of the rotating plate 5. Starting the motor 4 can drive the rotating plate 5 to rotate inside the first protective shell 7, thereby driving the silicon carbide rod to rotate for rotary spraying of the silicon carbide rod. This ensures the uniformity of the spraying and thus ensures that it has a good anti-oxidation effect. At the same time, there is no need for the operator to flip the rod, which reduces the operator's workload and improves work efficiency.

[0019] The fixing assembly includes a cylinder 8, the lower surface of which is fixedly mounted on the upper surface of the mounting bracket 2. The output end of the cylinder 8 is fixedly connected to a second protective shell 9. The lower surface of the second protective shell 9 is rotatably connected to a clamping plate 10. The lower surface of the clamping plate 10 is fixedly connected to a second anti-slip pad 11. Activating the cylinder 8 can push the second protective shell 9 downward so that the clamping plate 10 covers the top of the silicon carbide rod. Combined with the rotating plate 5, it can be squeezed and fixed to ensure that the rotating plate 5 can drive the silicon carbide rod to rotate.

[0020] The spraying assembly includes a water pump 12, the front surface of which is fixedly connected to the back of the support frame 1. The input end of the water pump 12 is fixedly connected to a feed pipe 13, and the output end of the water pump 12 is fixedly connected to a discharge pipe 14. One end of the discharge pipe 14 is fixedly connected to a concentrator 15, and the lower surface of the concentrator 15 is fixedly connected to a nozzle 16. When the water pump 12 is started, the anti-oxidation coating can be drawn from inside the liquid tank 17 through the feed pipe 13, enter the concentrator 15 through the discharge pipe 14, and be sprayed out by the nozzle 16. The concentrator 15 can make the anti-oxidation coating evenly distributed, thereby ensuring the uniformity of the spray from the nozzle 16, and thus ensuring the uniformity of the coating on the surface of the silicon carbide rod, and ensuring the coating quality.

[0021] Both sides of the lower surface of the concentrator 15 are fixedly connected to the upper surface of the second protective shell 9. The discharge pipe 14 is a flexible hose. The concentrator 15 can move up and down with the second protective shell 9 to spray the coating at the position closest to the silicon carbide rod, reducing waste. The flexible hose allows the discharge pipe 14 to correct its position by moving up and down with the second protective shell 9.

[0022] The support frame 1 has a liquid tank 17 fixedly connected inside. The back of the liquid tank 17 is fixedly connected to one end of the feed pipe 13. The liquid tank 17 is convenient for storing the anti-oxidation coating, which is then transported to the spray head 16 for spraying by the feed pipe 13.

[0023] The liquid tank 17 is fixedly connected to a fixed frame 18, and a filter screen 3 is fixedly connected to the fixed frame 18. The fixed frame 18 facilitates the installation and fixation of the filter screen 3. The filter screen 3 can filter out excess anti-oxidation coating generated during the spraying process so that it can enter the liquid tank 17 for recycling, thereby saving coating and reducing waste.

[0024] Both the first anti-slip pad 6 and the second anti-slip pad 11 are made of silicone. The first protective shell 7 and the second protective shell 9 are respectively provided with limiting grooves that are adapted to the rotating plate 5 and the clamping plate 10. The lower surface of the first protective shell 7 is fixedly connected to the upper surface of the support frame 1. The limiting groove limits the rotating plate 5 and the clamping plate 10, so that they can rotate smoothly inside the first protective shell 7 and the second protective shell 9. The first anti-slip pad 6 and the second anti-slip pad 11 can improve the stability of clamping and fixing the silicon carbide rod and ensure its effective and stable rotation.

[0025] Working steps: First, starting cylinder 8 pushes the second protective shell 9 down so that clamping plate 10 covers the silicon carbide rod. Combined with rotating plate 5, it can squeeze and fix the rod. Next, starting motor 4 drives rotating plate 5 to rotate inside the first protective shell 7, thereby rotating the silicon carbide rod. Second, starting water pump 12 draws the anti-oxidation coating from inside liquid tank 17 through feed pipe 13. The coating enters the collection plate 15 through discharge pipe 14 and is sprayed out by nozzle 16 to coat the silicon carbide rod. Finally, excess anti-oxidation coating generated during the spraying process falls onto filter screen 3, is filtered by filter screen 3, and then enters liquid tank 17 for recycling.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
