Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ammonia treatment equipment, specifically a flue gas treatment structure for quenching bare plates. Background Technology
[0002] Nitriding is a chemical heat treatment process in which nitrogen atoms diffuse into the surface layer of a workpiece in a certain medium at a certain temperature. Common types include liquid nitriding, gas nitriding, and ion nitriding. Traditional gas nitriding involves placing the workpiece in a sealed container, passing flowing ammonia gas through it, and heating it. After holding it at that temperature for a relatively long time, the ammonia gas thermally decomposes to produce active nitrogen atoms, which are continuously adsorbed onto the surface of the workpiece and diffuse into the surface layer, thereby changing the chemical composition and structure of the surface layer and obtaining excellent surface properties.
[0003] Before production, the raw slab needs to be nitrided to ensure mold quality. Nitriding requires ammonia, which can burn the skin, eyes, and mucous membranes of the respiratory organs. Direct emission of ammonia will pollute the air and harm the health of workers. Therefore, a fume treatment device for raw slab quenching is needed to treat the ammonia. However, while the existing device can treat ammonia, it is not convenient for subsequent recycling, resulting in waste of resources. Utility Model Content

Detailed Implementation

[0021] Please see Figure 1-4 This utility model is a flue gas treatment structure for quenching of bare plates, including a mounting base 1, and further including: a spray box 2 fixedly connected to the top of the mounting base 1, a water tank 3 fixedly connected to the top of the spray box 2, a water pump 4 fixedly installed on one side of the water tank 3, a spray head 5 fixedly connected to the bottom of the water pump 4, and the spray head 5 is located inside the mounting base 1, an exhaust port 6 fixedly connected to one side of the mounting base 1, an air inlet 7 fixedly connected to one side of the mounting base 1, a water pump 8 fixedly installed on the other side of the mounting base 1, a heating box 9 fixedly connected to one side of the water pump 8, and the heating box 9 is fixedly connected to the top of the mounting base 1, and a stirring mechanism is provided inside the heating box 9.
[0022] A disc 10 is fixedly connected to the top of the air inlet 7, and the disc 10 is fixedly installed inside the mounting base 1. Multiple sets of exhaust holes 11 are opened inside the disc 10. The exhaust gas generated after heat treatment is transported to the inside of the disc 10 through the air inlet 7. The disc 10 is located below the liquid surface. At the same time, multiple sets of exhaust holes 11 are opened inside the disc 10, which in turn transport the exhaust gas to the inside of the exhaust gas conveying device spray box 2.
[0023] During use, the exhaust gas generated after heat treatment is transported to the interior of the disc 10 through the air inlet 7, and then discharged through the exhaust port 11. This increases the contact area between ammonia and water, thereby increasing the processing efficiency of the equipment.
[0024] The stirring mechanism includes a motor 12, gear 13, stirring rods 14, and a toothed synchronous belt 15. Multiple stirring rods 14 are rotatably mounted inside the heating chamber 9. Gear 13 is fixedly connected to the bottom of the stirring rods 14. The toothed synchronous belt 15 is sleeved on the surface of gear 13, and gears 13 are connected to each other through the toothed synchronous belt 15. The motor 12 is fixedly connected to the bottom of gear 13 and is also fixedly mounted at the bottom of the heating chamber 9. A conical block 16 is fixedly connected inside the heating chamber 9, and a conveying pipe 17 is fixedly connected inside the conical block 16. The conveying pipe 17 is in a conical spiral shape. The heating box 9 has two fixedly connected conveying pipes 18, which are connected to the water tank 3. A drying chamber 19 is fixedly connected to the top of the heating box 9, and a filter cotton pad 20 is fixedly installed inside the drying chamber 19. A sealing door 21 is slidably installed inside the drying chamber 19. A handle 22 is fixedly connected to one side of the sealing door 21, and a connecting rod 23 is slidably connected inside the handle 22. Two sets of guide rods 24 are symmetrically fixedly connected to the bottom of the connecting rod 23. A rack 25 is fixedly connected to the bottom of the guide rod 24. A gear 26 is meshed with one side of the rack 25. A snap-fit block 27 is fixedly connected to the surface of the gear 26. Block 27 is rotatably connected to the sealing door 21; two sets of snap-fit blocks 28 are symmetrically fixedly connected to one side of the drying chamber 19, and the snap-fit blocks 28 can contact the surface of the snap-fit block 27. The motor 12 drives the gear 13 to rotate, and the gear 13 is fixedly connected to the stirring rod 14. The gears 13 are connected to each other by a toothed synchronous belt 15, which in turn drives the stirring rod 14 to rotate synchronously. At the same time, a conical block 16 is fixedly connected inside the heating box 9. A conveying pipe 17 is fixedly connected inside the conical block 16. The conveying pipe 17 is conical and spiral, and the conveying pipe 17 is fixedly connected to the conveying pipe 28. The second conveying pipe 18 is connected to the water tank 3. At the same time, the top of the heating box 9 is fixedly connected to the drying chamber 19. The inside of the drying chamber 19 is fixedly connected to the filter cotton pad 20. The drying chamber 19 is connected to the second snap-fit block 28 and is slidably connected to the sealing door 21. The sealing door 21 is fixedly connected to the handle 22. The handle 22 is slidably connected to the connecting rod 23. The connecting rod 23 is fixedly connected to the rack 25. The rack 25 meshes with the second gear 26. At the same time, the second gear 26 is fixedly connected to the first snap-fit block 27. The first snap-fit block 27 can contact the second snap-fit block 28, thereby realizing the quick disassembly and assembly of the sealing door 21.
[0025] In operation, motor 12 drives gear 13 to rotate, which in turn drives the stirring rod 14 to rotate via the toothed synchronous belt 15, accelerating the heating efficiency of the ammonia water. The resulting ammonia gas is then transported to the interior of the drying chamber 19 and dried by the desiccant placed on top of the filter cotton pad 20. Simultaneously, the conical block 16, in conjunction with the conveying pipe 17, condenses the generated steam, reducing the amount of water vapor entering the drying chamber 19, increasing the desiccant's lifespan, and reducing equipment production costs. When the desiccant needs to be replaced, the connecting rod 23 is pulled and slids along the inside of the handle 22, causing the guide rod 24 and rack 25 to move synchronously. This, in turn, causes gear 26 and locking block 27 to rotate, disengaging locking block 27 from locking block 28, thus enabling quick disassembly and assembly of the sealing door 21. This facilitates rapid replacement of the desiccant and increases the work efficiency of the staff.
[0026] Working principle: First, the equipment is installed in a suitable location. Then, the exhaust gas is conveyed to the interior of the disc 10 through the air inlet 7 and discharged through the exhaust port 11. At the same time, the exhaust gas is treated by water pump 4 and spray head 5. Then, ammonia water is conveyed to the interior of the heating box 9 by water pump 8 for heating. The motor 12 drives gear 13 to rotate, which in turn drives the stirring rod 14 to stir the ammonia water. The generated steam is condensed by the conical block 16 and the conveying pipe 17. Then, it is dried by the desiccant placed on the surface of the filter cotton pad 20. When the desiccant needs to be replaced, the connecting rod 23 is pulled and slids inside the handle 22, which drives the rack 25 to move. At the same time, the gear 26 rotates with the locking block 27, releasing the contact with the surface of the locking block 28, thereby realizing the replacement of the desiccant. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
