[0002] In the cement production process, the cement kiln burner is a key piece of equipment in the clinker calcination process. It plays a vital role in the calcination quality of the clinker in the kiln and the service life of the kiln lining. It mainly injects fuel (such as pulverized coal, fuel oil, natural gas, etc.) into the cement kiln and mixes it thoroughly with the combustion air to achieve an efficient and stable combustion process.

[0003] However, some old or simple cement kiln burners, due to their fixed position, often result in uneven heating within the kiln. Uneven combustion can lead to unstable clinker quality, with some areas being overheated while others are underheated. This uneven heating results in inconsistent clinker quality. While some adjustments can be made by workers, uneven heating still occurs, severely affecting product performance and quality stability. Therefore, a reciprocating adjustment device for cement kiln burners is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a cement kiln burner reciprocating adjustment device, including a cement rotary kiln 1 that can process cement raw materials into cement clinker. The cement rotary kiln 1 is an existing structure and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. A base plate 4 is provided on the left side of the cement rotary kiln 1 to provide support. A burner 2 is provided at the top of the base plate 4 to inject fuel such as pulverized coal, fuel oil, natural gas, etc. into the cement kiln and mix it fully with the combustion air to achieve a high-efficiency and stable combustion process. The burner 2 is an existing structure and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. The burner 2 is located on the left side of the cement rotary kiln 1. A roller 5 is fixedly installed at the bottom end of the base plate 4 to support the base plate 4 and provide a support point for the movement of the base plate 4. A reciprocating assembly is provided on the front surface of the burner 2. The reciprocating assembly includes a turntable 3 that drives the guide rod 35 to rotate.

[0032] Furthermore, a support frame 31 for supporting the motor 32 and the turntable 3 is fixedly connected to the left side of the cement rotary kiln 1. A guide frame 34 for driving the bottom plate 4 to move back and forth is fixedly connected to the top of the bottom plate 4 near the rear of the turntable 3. An adjustment component is provided on the rear surface of the turntable 3 away from the center. The adjustment component includes a guide rod 35 that is slidably connected inside the guide frame 34 and drives the guide frame 34 to move back and forth. The guide rod 35 is set at a position away from the center of the turntable 3. At this time, the rotation of the turntable 3 can drive the guide rod 35 to rotate around the center point of the turntable 3. Thus, the guide rod 35 rotates and is slidably connected to the inner wall of the guide frame 34, so that the guide frame 34 moves back and forth with the guide rod 35. Through this back and forth movement, the flame of the burner 2 can evenly cover the material in the kiln, ensuring that the material is heated evenly, thereby improving the quality and output of cement clinker. The guide rod 35 is slidably connected to the inner wall of the guide frame 34.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The adjustment assembly also includes a guide block 6 that supports the guide rod 35 and can adjust the position of the guide rod 35. The guide block 6 is fixedly connected to the front surface of the guide rod 35. The guide block 6 passes through and is slidably connected to the inner wall of the turntable 3. The turntable 3 supports the guide block 6. The front surface of the turntable 3 has a slot 66 that limits the slide rod 65, the guide block 6, and the guide rod 35 by sliding the slot 64 into the slot 66. Multiple sets of slots 66 are provided on the front surface of the turntable 3. The multiple sets of slots 66 can be used with the slot 64 to adjust the position of the guide rod 35. The front surface of the guide block 6 has a circular groove 61 that provides space for the circular block 62 and the spring 63. The front surface of the guide block 6 is slidably connected to the slide rod 65 that drives the slot 64 and the circular block 62 to move.

[0034] Reference Figure 2 , Figure 3 and Figure 4 A motor 32 that drives the turntable 3 to rotate is fixedly installed on the front surface of the middle part of the support frame 31. The motor 32 is an existing structure and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case. The turntable 3 is fixedly connected to the rear surface of the output shaft of the motor 32. The output shaft of the motor 32 passes through and is rotatably connected to the middle part of the support frame 31. A track 33 that supports the rollers 5 and increases the stability of the movement of the rollers 5 is fixedly installed on the left side of the cement rotary kiln 1 near the bottom plate 4. The rollers 5 are slidably connected to the inner wall of the track 33.

[0035] Reference Figure 1 , Figure 4 and Figure 5 A circular block 62 is fixedly connected to the rear surface of the slide rod 65, supporting the slide rod 65 and preventing it from sliding out of the guide block 6. The circular block 62 is slidably connected to the inner wall of the circular groove 61. The circular block 62 and the guide block 6 are elastically connected by a spring 63. One end of the spring 63 is fixedly connected to the front surface of the circular block 62, and the other end of the spring 63 is fixedly connected to the inner wall of the front surface of the circular groove 61. The spring 63 is sleeved on the outer wall of the slide rod 65. By pulling the slide rod 65, the locking block 64 is slid out of the locking groove 66, and at the same time, the circular block 62 moves to compress the spring 63. At this time, the guide block 6 and the guide block 6 are connected. When the guide rod 35 is released from its limit, the sliding rod 65 moves the guide block 6, thereby adjusting the position of the guide rod 35. By changing the position of the guide rod 35, the reciprocating distance of the burner 2 can be adjusted. By controlling the reciprocating distance, the combustion effect can be optimized, thus ensuring the high quality of the product. A locking block 64 is fixedly connected to the middle of the sliding rod 65 near the front of the guide block 6. This locking block 64 slides into the locking groove 66 and limits the guide block 6 and the guide rod 35. The locking block 64 slides on the inner wall of the locking groove 66 and on the front surface of the guide block 6.

[0036] Working principle: When in use, the motor 32 is started, and the output shaft of the motor 32 rotates, driving the turntable 3, which is fixedly connected to it, to rotate. When the turntable 3 rotates, it drives the guide rod 35, which is located away from the center, to rotate around the center point of the turntable 3. Since the guide rod 35 is slidably connected to the inner wall of the guide frame 34, the rotation of the guide rod 35 will drive the guide frame 34 to move back and forth. At the same time, the guide rod 35 is slidably connected to the inner wall of the guide frame 34, and the guide frame 34 is fixedly connected to the top of the base plate 4. The roller 5 at the bottom of the base plate 4 is slidably connected to the inner wall of the track 33. Therefore, the reciprocating movement of the guide frame 34 will drive the base plate 4 and the burner 2 installed at the top of the base plate 4 to move back and forth. Through this reciprocating movement, the flame of the burner 2 can evenly cover the material in the kiln, ensuring that the material is heated evenly, thereby improving the quality and output of cement clinker.

[0037] When it is necessary to adjust the reciprocating distance of the burner 2, by pulling the slide rod 65 outward, the locking block 64 is slid out of the slot 66, and at the same time, the round block 62 moves on the inner wall of the round groove 61 to compress the spring 63. At this time, the limit of the guide block 6 and the guide rod 35 is released. Moving the slide rod 65 drives the guide block 6 to move, thereby adjusting the position of the guide rod 35. The reciprocating distance is increased by adjusting it to a position away from the center of the turntable 3, or decreased by adjusting it to a position closer to the center of the turntable 3. Through the multiple sets of slots 66 set on the front surface of the turntable 3, the position of the guide rod 35 can be adjusted to different degrees in conjunction with the locking block 64. After changing the position of the guide rod 35, the reciprocating distance of the burner 2 can be adjusted. By controlling the reciprocating distance, the combustion effect is ensured to reach the best state, thereby ensuring the high quality of the product.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
