[0001] This utility model relates to the field of rotary kiln equipment technology, and in particular to a rotary kiln cover opening support structure. Background Technology

[0002] Rotary kiln equipment is a key piece of equipment used in industrial production for calcination and roasting of materials. It is widely used in industries such as cement, metallurgy, and chemicals. As an important part of the kiln body, the furnace cover needs to be kept sealed during production to maintain a stable temperature and pressure environment inside the kiln. It needs to be opened during maintenance, feeding, or slag removal.

[0003] In existing technologies, the opening of traditional rotary kiln covers mostly relies on manual operation. Manual opening is labor-intensive, inefficient, and the opening angle is limited, which is not conducive to comprehensive observation and maintenance operations, and affects operational safety. At the same time, most existing support structures do not have limit locking functions, and are prone to accidental closure due to external forces or their own weight, posing safety hazards and causing equipment or personnel injuries. Therefore, improvements are needed. Utility Model Content

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a rotary kiln cover opening support structure, including a kiln frame 1 and a kiln cover body 2. A rotating block 3 is fixedly installed on the side of the kiln cover body 2, and a rotating rod 4 is fixedly installed inside the rotating block 3. A bevel gear 5 is fixedly installed at one end of the rotating rod 4. A transmission rod 6 is rotatably connected inside the kiln frame 1. A bevel gear 7 is fixedly installed at one end of the transmission rod 6, and a bevel gear 8 is fixedly installed on the surface of the transmission rod 6. A drive motor 9 is fixedly installed inside the kiln frame 1, and a bevel gear 10 is fixedly installed at the output end of the drive motor 9. A mounting base 11 is fixedly installed on the side of the furnace cover 2. A limiting rod 12 is rotatably connected inside the mounting base 11. A limiting groove 13 is opened on the side of the furnace cover body 2. An anti-slip groove 14 is opened at one end of the limiting rod 12. A fixing buckle 15 is provided on the outer edge of the furnace frame 1. The rotating rod 4 is rotatably connected to the furnace frame 1. The first bevel gear 5 and the second bevel gear 7 mesh and drive each other. The fourth bevel gear 10 and the third bevel gear 8 mesh and drive each other. The fixing buckle 15 is fixedly connected to the outer surface of the furnace frame 1 and the outer surface of the furnace cover body 2 respectively. One end of the limiting rod 12 is engaged with the limiting groove 13.

[0023] In this embodiment, the drive motor 9 drives the bevel gear 10 to rotate. The bevel gear 10 meshes with the bevel gear 8 to rotate the transmission rod 6. The bevel gear 7 of the transmission rod 6 meshes with the bevel gear 5 of the rotating rod 4, driving the rotating rod 4 and the rotating block 3 to rotate, thereby realizing the automatic opening and closing of the furnace cover. This reduces the intensity of manual operation and improves the convenience and efficiency of opening the rotary kiln furnace cover. In addition, a limiting rod 12 is set inside the mounting base 11, and a limiting groove 13 is opened on the side of the furnace cover body 2, so that the limiting rod 12 can be engaged into the limiting groove 13 to limit and fix the opening angle of the furnace cover. This prevents the furnace cover from shaking or accidentally closing due to external force when it is open, improving the stability and safety during use. A fixing buckle 15 is set between the furnace frame 1 and the furnace cover body 2, so that the furnace cover can be quickly locked and fixed by the buckle when closed, improving the sealing and stability of the furnace cover connection. At the same time, it is convenient for operators to quickly complete the opening or closing action, improving the convenience of equipment use.

[0024] Example 2: As Figures 1-4 As shown, the side of the furnace cover body 2 is provided with a sealing gasket A16, and the inside of the furnace frame 1 is provided with a sealing gasket B17. The furnace cover body 2 is a split structure, and the sealing gasket A16 is located between the two furnace cover bodies 2.

[0025] In this embodiment, by setting a sealing gasket A16 on the side of the furnace cover body 2 and a sealing gasket B17 on the inside of the furnace frame 1, the two sealing gaskets work together when the furnace cover is closed to form a double sealing structure, which effectively prevents the leakage of high-temperature gas or dust inside the furnace, and improves the sealing performance and safety of the equipment.

[0026] The working principle of this embodiment: When using the rotary kiln cover opening support structure, when opening the cover, the operator first confirms that the cover is in the closed state and releases the fixing buckle 15 connecting the furnace frame 1 and the outer side of the cover body 2. Then, the drive motor 9 is started, so that the output end of the drive motor 9 drives the bevel gear 4 10 to rotate. The bevel gear 4 10 meshes with the bevel gear 3 8 on the transmission rod 6, causing the transmission rod 6 to rotate. The bevel gear 2 7 at one end of the transmission rod 6 rotates accordingly and meshes with the bevel gear 1 5 on the rotating rod 4, causing the rotating rod 4 to rotate along its axis. The rotation of the rotating rod 4 causes the cover body 2 to rotate outward around the axis of the rotating block 3, realizing the opening action of the cover. When the furnace cover is rotated to the set angle, the operator rotates the limiting rod 12 inside the mounting base 11 outward and presses it down, so that one end of the limiting rod 12 is engaged in the limiting groove 13 on the side of the furnace cover body 2, thereby fixing the opening angle of the furnace cover and preventing the furnace cover from shaking or accidentally closing due to external force. After the limiting rod 12 is engaged in the limiting groove 13, the anti-slip groove 14 at the end of the limiting rod 12 is in close contact with the inner wall of the limiting groove 13, enhancing the stability of the limiting connection. At this time, the furnace cover is in a stable open state, and maintenance personnel can enter the kiln body to perform inspection, ash cleaning, or replacement of refractory materials. After the operation is completed, the operator first pulls the limiting rod 12 out of the limiting groove 13, and then restarts the drive motor 9 to rotate the furnace cover body 2 inward to reset until it is completely closed. During the closing process, the sealing gasket A16 on the side of the furnace cover body 2 and the sealing gasket B17 on the inner side of the furnace frame 1 are tightly fitted to form a double sealing structure to ensure the sealing performance after the furnace body is closed. Finally, the operator will re-fasten the fixing buckle 15.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
