Description

Technical Field

[0001] This utility model belongs to the field of rotary kiln technology, and relates to cleaning functions, specifically a rotary kiln with a cleaning function. Background Technology

[0002] A rotary kiln is a type of furnace used for high-temperature calcination and heat treatment, widely applied in many industrial processes. Its basic structure is an inclined, rotating cylindrical body that continuously feeds solid materials (such as ores, gypsum, coal, alumina, etc.) and heats them internally to achieve the desired chemical reactions or physical changes. Its working principle involves material being fed from one end, heated by high-temperature gas during rotation, and finally discharged from the other end after processing. Rotary kilns offer advantages such as continuous processing, mass production, simple equipment structure, and high thermal efficiency, playing a vital role in cement manufacturing, magnesium production, metal smelting, and fertilizer production.

[0003] However, some existing rotary kilns are prone to accumulating dirt and clumps on their inner walls during use. This dirt and clumps reduce heat transfer efficiency, causing uneven hot and cold spots, which affects the calcination or heat treatment effect, resulting in insufficient material processing or substandard results. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotary kiln with a cleaning function. The technical problem this invention aims to solve is that the inner wall is prone to accumulating dirt and clumps, which reduces heat transfer efficiency, resulting in uneven hot and cold spots, thus affecting the calcination or heat treatment effect, leading to insufficient material processing or substandard results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rotary kiln with a cleaning function includes a base, a main body on top of the base, a cleaning roller rotatably connected to the side of the base away from the base, three scrapers fixedly connected to the surface of the cleaning roller, and the three scrapers are evenly arranged in a ring. The cleaning roller and scrapers cooperate with the inner wall of the main body. A fourth gear is fixedly sleeved at both ends of the cleaning roller, and a rotating mechanism for rotating the cleaning roller is provided on the surface of the two fourth gears. A first toothed ring is fixedly sleeved on the surface of the main body, and a rotating mechanism for rotating the main body is provided at the bottom of the first toothed ring. The arrangement of the cleaning roller and scrapers can prevent dirt from adhering to the inner wall of the main body.

[0006] As a further embodiment of this utility model, the rotating mechanism includes two limiting frames, both of which are fixedly connected to the top of the base. The top of the two limiting frames is fixedly connected to the same support frame. The bottom of the support frame near the two fourth gears is fixedly connected to a side plate. The cleaning roller is rotatably connected between the two side plates. The two side plates are rotatably connected to the same rotating shaft. The surface of the rotating shaft near the two fourth gears is fixedly fitted with a third gear, and the third gear and the fourth gear are configured to cooperate with each other. The surface of the main body is fixedly fitted with a second toothed ring, and the surface of the second toothed ring is fitted with a second gear. The second gear is fixedly fitted onto the surface of the rotating shaft. The cleaning roller can be rotated by the setting of the third gear.

[0007] As a further embodiment of this utility model, the rotating mechanism includes a motor, which is fixedly connected inside the base. The output shaft of the motor is fixedly connected to a first gear via a coupling, and the first gear and a first gear ring are mutually engaged. Three second support rollers are fixedly sleeved on the surface of the main body, and two first support rollers are engaged at the bottom of each of the three second support rollers. The two first support rollers are rotatably connected to the top of the base. Limiting rings are fixedly sleeved on the surface of the main body near the two limiting frames, and the two limiting rings are rotatably connected inside the limiting frames. The main body can be rotated by the first gear.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model employs a cleaning roller and scraper to clean the inner wall of the main body, thus preventing dirt from adhering to the inner wall. This effectively solves the problem of dirt and clumps easily adhering to the inner wall, which reduces heat conduction efficiency, causing uneven hot and cold spots, affecting the calcination or heat treatment effect, and leading to insufficient material processing or substandard results. A cleaning roller is installed at the bottom of the support frame, and the cleaning roller is in contact with the inner wall of the main body to achieve the purpose of cleaning dirt. Three scrapers are also provided on the surface of the cleaning roller, and the three scrapers also cooperate with the main body to further ensure the removal of dirt. A fourth gear is installed at both ends of the cleaning roller, and the fourth gear cooperates with the third gear at one end of the rotating shaft. A second toothed ring is also provided on the surface of the main body, and the second toothed ring cooperates with the second gear on the surface of the rotating shaft. Thus, when the second toothed ring rotates, the cleaning roller also rotates synchronously, thereby ensuring a better cleaning effect of the cleaning roller. Attached Figure Description
