[0002] During the operation of the roasting furnace, the spray gun is used to spray various liquids into the furnace, such as combustion aids and additives, which play an important auxiliary role in the roasting process.

[0003] Existing roasting furnace spray guns have some problems in use, such as inconvenient height adjustment, making it difficult to accurately adjust the spray height according to different working areas and conditions in the roasting furnace; the angle adjustment of the spray gun is also not flexible enough, making it impossible to accurately spray the liquid to the designated position, which makes it impossible to accurately meet the needs of different roasting processes in actual use, thus affecting the quality of roasted products and production efficiency. Therefore, we propose a roasting furnace spray gun. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1 A roasting furnace spray gun includes a mounting base 1. A fixed frame 3 is mounted on the bottom of the mounting base 1 via a lifting mechanism 2. The lifting mechanism 2 is used to drive the fixed frame 3 to rise and fall. A telescopic rod 4 is fixedly fixed to the bottom of the mounting base 1. The telescopic rod 4 is fixedly connected to the fixed frame 3. A rotating shaft 5 is rotatably mounted inside the fixed frame 3. A rotating mechanism 6 for driving the rotating shaft 5 to rotate is installed inside the side of the fixed frame 3. A mounting plate 8 is fixedly sleeved on the rotating shaft 5. A spray gun body 9 is fixedly sleeved inside the mounting plate 8. A liquid inlet pipe 10 is connected to the spray gun body 9.

[0022] Reference Figure 2 , Figure 3 The rotating mechanism 6 includes a second motor 61, a worm 62, a second lead screw 63, a worm wheel 64, a second slider 65, a rack 66, and a gear 67. The second motor 61 is mounted on the side of the fixed frame 3. The output shaft of the second motor 61 rotates through the fixed frame 3 and is connected to the worm 62. The second lead screw 63 is rotatably mounted inside the fixed frame 3. The worm wheel 64 is fixedly sleeved on the second lead screw 63, and the worm 62 meshes with the worm wheel 64 for transmission. The second slider 65 is threadedly sleeved on the second lead screw 63. A guide groove is provided inside the fixed frame 3. A guide block 7 is fixed to the side of the second slider 65 and slides on the guide. Inside the groove, a rack 66 is fixed to the side of the second slider 65, and a gear 67 is fixedly sleeved on the rotating shaft 5. The rack 66 and the gear 67 mesh and drive each other. When the second motor 61 is started, the worm gear 62 meshes and drives the worm wheel 64. The worm wheel 64 drives the second lead screw 63 to rotate. Through the threaded transmission between the second lead screw 63 and the second slider 65, the second slider 65 drives the rack 66 to move up and down. Through the meshing transmission between the rack 66 and the gear 67, the gear 67 drives the rotating shaft 5 to rotate, which in turn drives the mounting plate 8 to rotate. This allows the mounting plate 8 to drive the spray gun body 9 to rotate, facilitating the adjustment of the angle of the spray gun body 9.

[0023] Reference Figure 4The lifting mechanism 2 includes a first motor 21, a first lead screw 22, a first slider 23, and a connecting rod 24. The first motor 21 is mounted on the side of the mounting base 1. The output shaft of the first motor 21 rotates through the mounting base 1 and is connected to the first lead screw 22. Two first sliders 23 are connected to the first lead screw 22 by threads with opposite directions. The mounting base 1 has a sliding groove inside, and the first sliders 23 are slidably mounted in the sliding groove. The bottom of the first sliders 23 is hinged to the connecting rod 24, which is hinged to the fixed frame 3. When the first motor 21 is started, the two first sliders 23 drive the connecting rod 24 to move through the threaded transmission between the first lead screw 22 and the first sliders 23, causing the connecting rod 24 to drive the fixed frame 3 to move up and down. This allows the fixed frame 3 to indirectly drive the spray gun body 9 to move up and down, facilitating the adjustment of the height of the spray gun body 9.

[0024] Working Principle: Based on different working areas and actual conditions within the roasting furnace, when adjusting the height of the spray gun 9 is necessary to process different types and stacking heights of materials, the first motor 21 is activated. Through the threaded transmission between the first lead screw 22 and the first slider 23, the two first sliders 23 drive the connecting rod 24 to move, causing the connecting rod 24 to lift and lower the fixed frame 3. This indirectly allows the fixed frame 3 to move the spray gun body 9 up and down, facilitating height adjustment of the spray gun body 9, meeting different spraying requirements, and improving the adaptability of roasting operations. When the spray angle of the spray gun 9 needs to be adjusted due to the variety of material shapes, arrangements, or stacking patterns, the second motor 61 is started. Through the meshing transmission of the worm gear 62 and the worm wheel 64, the worm wheel 64 drives the second lead screw 63 to rotate. Through the threaded transmission of the second lead screw 63 and the second slider 65, the second slider 65 drives the rack 66 to move up and down. Through the meshing transmission of the rack 66 and the gear 67, the gear 67 drives the rotating shaft 5 to rotate, which in turn drives the mounting plate 8 to rotate. This allows the mounting plate 8 to drive the spray gun body 9 to rotate, facilitating the adjustment of the spray gun body 9's angle.

[0025] After the spray gun body 9 is adjusted to a suitable height and angle, the liquid to be sprayed is delivered into the spray gun through the liquid inlet pipe 10. The spray gun can then spray liquid into the roasting furnace at the set height and angle to assist the normal operation of the roasting process. Throughout the entire working process, the spray gun has a stable structural design and can maintain a stable working state, ensuring the accuracy and consistency of liquid spraying.

[0026] In this case, multiple nozzles can be added to the spray gun body 9. At the same time, a series of facilities such as motors, circuits, and spray gun bodies are made of high-temperature resistant materials. For example, the motor is a high-temperature permanent magnet synchronous motor, and the circuit is made of high-temperature resistant cables such as silicone rubber insulated cables, which can meet the working conditions in the facility's roasting furnace.

[0027] 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.
