Technical Field

[0001] The utility model belongs to the technical field of preheating kilns, and particularly relates to a preheating kiln with a strengthening mechanism. Background Technique

[0002] A preheating kiln is a device that plays an important role in industrial production. It is mainly used to preheat materials before they enter the subsequent high-temperature treatment stage. The preheating kiln effectively raises the temperature of the materials through specific heating methods and design structures, making them reach a certain preheating standard. This can reduce energy consumption in the subsequent processing, improve production efficiency, and also help optimize product quality and production processes. For example, in cement production, the preheating kiln can enable raw materials to obtain sufficient heat before entering the rotary kiln for calcination, thereby reducing energy consumption during calcination and ensuring the stable quality of cement clinker.

[0003] In the prior art, many preheating kilns have adopted strengthening mechanisms to improve structural stability and safety, but there are still deficiencies in the uniformity of material preheating. Traditional preheating kilns often have significant local temperature differences due to uneven distribution of hot air flow, uneven material accumulation, or unreasonable layout of heating elements, which affects the preheating effect of the materials. This uneven preheating not only reduces production efficiency but may also have an adverse impact on subsequent production processes, such as increasing energy consumption and reducing product quality. Therefore, improvements are needed. For this reason, a preheating kiln with a strengthening mechanism is proposed. Summary of the Utility Model

Uniformly distributed material dropping ports are arranged on the connecting part. The material dropping ports are respectively communicated with the conveying pipe, the outer cylinder, and the inner cylinder. A first rotating rod is rotatably arranged in the middle of the conveying pipe. A spiral blade is arranged in the conveying pipe. The spiral blade is fixedly installed with the first rotating rod. A second rotating rod is rotatably arranged in the middle of the inner cylinder. Uniformly distributed movable plates are fixedly installed on the second rotating rod. A driving member is arranged on the side of the inner cylinder for driving the movable plates and the spiral blade to rotate simultaneously.

[0006] Preferably, the driving member includes a motor fixedly installed on the side of the inner cylinder, a driving wheel rotatably arranged on the side of the inner cylinder, a driven wheel fixedly installed at one end of the rotating rod, and a belt sleeved on the driving wheel and the driven wheel.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0022] A preheating kiln with a strengthening mechanism includes an outer cylinder 1 and an inner cylinder 2. The outer cylinder 1 and the inner cylinder 2 are connected by evenly distributed anchor bolts. A feeding pipe 3 and a conveying pipe 4 are arranged above the outer cylinder 1. One end of the feeding pipe 3 and the conveying pipe 4 are communicated. A connecting part 5 is fixedly installed between the outer cylinder 1 and the conveying pipe 4. The connecting part 5 is provided with evenly distributed material dropping openings 6. The material dropping openings 6 are respectively communicated with the conveying pipe 4, the outer cylinder 1, and the inner cylinder 2. A first rotating rod 7 is rotatably arranged in the middle of the conveying pipe 4. A spiral blade 8 is arranged in the conveying pipe 4. The spiral blade 8 is fixedly installed with the first rotating rod 7. A second rotating rod 9 is rotatably arranged in the middle of the inner cylinder 2. Evenly distributed movable plates 10 are fixedly installed on the second rotating rod 9. A driving member 11 is arranged on the side of the inner cylinder 2 for driving the movable plates 10 and the spiral blade 8 to rotate simultaneously. The driving member 11 includes a motor 111 fixedly installed on the side of the inner cylinder 2, a driving wheel 112 rotatably arranged on the side of the inner cylinder 2, a driven wheel 113 fixedly installed at the end of the first rotating rod 7, and a belt 114 sleeved on the driving wheel 112 and the driven wheel 113. The end of the output shaft of the motor 111 and the end of the second rotating rod 9 are respectively fixedly installed in the middle of the driving wheel 112. The belt 114 is respectively in transmission connection with the driving wheel 112 and the driven wheel 113;

[0023] During use, the material to be preheated enters the end of the conveying pipe 4 from the feeding pipe 3. Start the motor 111 on the side of the inner cylinder 2 of the motor 111. The output shaft of the motor 111 rotates to drive the driving wheel 112 to rotate. Through the transmission of the belt 114, the driven wheel 113 is driven to rotate, so that the first rotating rod 7 and the second rotating rod 9 rotate simultaneously. The spiral blade 8 on the first rotating rod 7 pushes the material to move in the conveying pipe 4 and falls into the outer cylinder 1 through the evenly distributed material dropping openings 6 and finally enters the inner cylinder 2, so that the material is evenly scattered in the inner cylinder 2. Then, the material is evenly preheated. The outer cylinder 1 and the inner cylinder 2 are connected by evenly distributed anchor bolts made of high-strength alloy material, which ensures the structural stability. The movable plates 10 on the second rotating rod 9 stir the material during rotation, improving the uniformity of the material preheating. This preheating kiln with a strengthening mechanism can effectively improve the uniformity of the material preheating, providing a better quality and stable material basis for the subsequent production process, and has strong practicability.

[0024] The movable plate 10 is provided with through holes 12 evenly distributed thereon;

[0025] When the second rotating rod 9 drives the movable plate 10 to rotate, it can drive the material to rotate and stir, promoting the mixing and heat exchange between the materials. The through holes 12 evenly distributed on the movable plate 10 allow the heat to better penetrate the material during the stirring process, further improving the uniformity of the material's heat absorption.

[0026] The rivets are made of high-strength alloy material;

[0027] The rivets made of high-strength alloy material have excellent strength and high-temperature resistance. When the preheating kiln is working, the inner cylinder 2 and the outer cylinder 1 will bear high temperature and the pressure of the material. The rivets can firmly connect the outer cylinder 1 and the inner cylinder 2, ensuring the stability of the whole structure and preventing the structure from deforming or being damaged due to temperature changes and mechanical actions.

[0028] The outer cylinder 1 is a strong steel structure shell, and the inner cylinder 2 is a high-temperature resistant refractory lining;

[0029] The outer cylinder 1 adopts a strong steel structure shell, providing strong support and protection for the whole preheating kiln, and can withstand external pressure and impact. The high-temperature resistant refractory lining of the inner cylinder 2 is in direct contact with the high-temperature material, having good heat insulation and heat resistance properties, effectively maintaining the temperature inside the inner cylinder 2, reducing heat loss, and at the same time preventing the outer cylinder 1 from being damaged by high temperature, ensuring the efficient and stable operation of the preheating kiln.

[0030] A controller is arranged on the outer wall of the outer cylinder 1, and the controller is electrically connected to the motor 111;

[0031] The controller arranged on the outer wall of the outer cylinder 1 is electrically connected to the motor 111. The operator can precisely set the rotation speed and operation time of the motor 111 through the controller, and flexibly adjust the working parameters of the motor 111 according to different material characteristics and preheating requirements, so as to control the conveying speed of the spiral blade 8 of the first rotating rod 7 and the stirring speed of the movable plate 10 on the second rotating rod 9, realizing the precise control of the material preheating process to achieve the best preheating effect.

[0032] Working principle:

[0033] During use, the material to be preheated enters the end of the conveying pipe 4 from the feeding pipe 3. Start the motor 111 on the side of the inner cylinder 2 of the motor 111. The output shaft of the motor 111 rotates to drive the driving wheel 112 to rotate. Through the transmission of the belt 114, the driven wheel 113 is driven to rotate, so that the first rotating rod 7 and the second rotating rod 9 rotate simultaneously. The spiral blade 8 on the first rotating rod 7 pushes the material to move in the conveying pipe 4, and falls into the outer cylinder 1 through the uniformly distributed material dropping ports 6 and finally enters the inner cylinder 2, so that the material is evenly scattered in the inner cylinder 2. Then, the material is uniformly preheated. The outer cylinder 1 and the inner cylinder 2 are connected by uniformly distributed anchor bolts made of high-strength alloy material, ensuring the structural stability. The movable plate 10 on the second rotating rod 9 stirs the material during rotation, improving the uniformity of material preheating;

[0034] When the second rotating rod 9 drives the movable plate 10 to rotate, it can drive the material to rotate and stir, promoting the mixing and heat exchange between the materials. The uniformly distributed through holes 12 on the movable plate 10 can allow the heat to better penetrate the material during the stirring process of the material, further improving the uniformity of the material being heated;

[0035] The controller provided on the outer wall of the outer cylinder 1 is electrically connected to the motor 111. The operator can precisely set the rotation speed and operation time of the motor 111 through the controller, and flexibly adjust the working parameters of the motor 111 according to different material characteristics and preheating requirements, so as to control the conveying speed of the spiral blade 8 of the first rotating rod 7 and the stirring speed of the movable plate 10 on the second rotating rod 9, realizing the precise control of the material preheating process to achieve the best preheating effect;

[0036] This preheating kiln with a strengthening mechanism can effectively improve the uniformity of material preheating, providing a better quality and stable material basis for subsequent production processes, with strong practicability;

[0037] The anchor bolts made of high-strength alloy material have excellent strength and high-temperature resistance. When the preheating kiln is working, the inner cylinder 2 and the outer cylinder 1 will bear high temperature and the pressure of the material. The anchor bolts can firmly connect the outer cylinder 1 and the inner cylinder 2, ensuring the stability of the entire structure and preventing structural deformation or damage caused by temperature changes and mechanical actions;

[0038] The outer cylinder 1 adopts a strong steel structure shell, providing strong support and protection for the entire preheating kiln, capable of withstanding external pressure and impact. The high-temperature resistant and fireproof material lining of the inner cylinder 2 is in direct contact with the high-temperature material, having good heat insulation and heat resistance properties, effectively maintaining the temperature inside the inner cylinder 2, reducing heat loss, and at the same time preventing the outer cylinder 1 from being damaged by high temperature, ensuring the efficient and stable operation of the preheating kiln.

[0039] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
