Description

Technical Field

[0001] This utility model relates to the field of calcium aluminate powder processing technology, and in particular to a calcium aluminate powder calcination equipment. Background Technology

[0002] Calcium aluminate powder calcination equipment is mainly used to produce calcium aluminate powder (the main components are calcium aluminate and some oxides). Calcium aluminate powder is commonly used in cement, building materials, ceramics, and other industrial fields, especially in high-temperature calcination processes, where it provides the necessary chemical reactivity.

[0003] Rotary kilns are commonly used equipment in the calcination process of calcium aluminate powder, suitable for high-temperature calcination reactions. They ensure uniform heating of the material through continuous rotation, enabling the calcination reaction of calcium aluminate at relatively high temperatures (typically between 1200°C and 1500°C).

[0004] During long-term high-temperature operation, the outer wall of the existing rotary kiln is subjected to continuous high temperatures, which may cause thermal expansion or deformation. Since the rotary kiln is a rotating device, when its outer wall deforms, the overall geometry of the rotary kiln will deviate, resulting in uneven stress during rotation. Specifically, the deformation of the outer wall may cause the circumference of the rotary kiln to deviate from the original design trajectory, or cause local warping, bending, and other phenomena. This deformation causes uneven friction or impact in the area where the rotary kiln contacts the support frame, which in turn causes the support system to bear an unbalanced load. Utility Model Content

[0031] 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.

[0032] Example 1, please refer to Figures 1 to 6 This utility model provides a technical solution: a calcium aluminate powder calcination device, including a rotary kiln body 1. Support members 101 are movably fitted on both sides of the outer surface of the rotary kiln body 1. Support assemblies are provided on both sides of the inner surface of the two support members 101. Each support assembly includes multiple dampers 102. The outer sides of the multiple dampers 102 are fixedly installed on the inner wall of the support member 101. A first positioning wheel 104 is provided at the other end of each damper 102. The first positioning wheel 104 is movably connected to the outer surface of the rotary kiln body 1. Multiple first return springs 103 are provided on the outer side of the first positioning wheel 104. The other ends of the multiple first return springs 103 are fixedly installed on the inner wall of the support member 101. A push rod 105 is fixedly installed at the center of the outer side of the first positioning wheel 104. An air cylinder 106 is movably fitted on the outer surface of the push rod 105. The air cylinder 106 is fixedly installed on the support member 101. Inside component 101, a movable plate 107 is fixedly installed on the outer side of push rod 105. The movable plate 107 is slidably connected to the inside of air cylinder 106. An air pipe 108 is provided on the outer side of air cylinder 106. A first support column 109 is provided at the other end of air pipe 108. The first support column 109 is fixedly installed on the top side inside the support component 101. A second support column 110 is slidably connected inside the first support column 109. A second return spring 111 is fixedly installed on the outer side of the second support column 110. The other end of the second return spring 111 is fixedly installed inside the first support column 109. A second positioning wheel 112 is provided at the other end of the second support column 110. The second positioning wheel 112 is movably connected to the outer surface of rotary kiln body 1. Positioning columns 113 are fixedly installed on both sides of the second positioning wheel 112. Both positioning columns 113 are slidably connected inside the support component 101.

[0033] In this embodiment, when the rotary kiln body 1 deforms, it squeezes the first positioning wheel 104, causing the first positioning wheel 104 to move outward. The first positioning wheel 104 also compresses the damper 102 and the first return spring 103 on the support member 101. As the first positioning wheel 104 moves, it simultaneously squeezes the push rod 105, which in turn squeezes the movable plate 107, allowing it to slide inside the air cylinder 106. When the movable plate 107 slides, it compresses the air inside the air cylinder 106, causing it to enter the first support column 109 through the air pipe 108. Once the air enters the first support column 109, it can push the second support column 110 through the air pressure, allowing it to slide inward inside the first support column 109, while simultaneously pulling the second return spring 110. The second positioning wheel 112 at the top can be pushed inward by the second support column 110. When the second positioning wheel 112 moves, it will simultaneously pull the positioning column 113 to slide inside the support member 101, so that it can fit more closely to the outer surface of the rotary kiln body 1. Through the structure of the first positioning wheel 104 and the air cylinder 106, the structure can be automatically adjusted when the rotary kiln body 1 deforms, ensuring that the positioning wheel always keeps in contact with the outer surface of the rotary kiln. This avoids unstable operation caused by the deformation of the rotary kiln and ensures the normal operation of the equipment. At the same time, through the cooperation of the support components, the load change caused by the deformation of the outer wall of the rotary kiln body 1 can be effectively reduced, reducing the friction and wear of the rotary kiln body 1 when rotating on the support member 101, and extending the service life of the equipment.

[0034] Example 2, as Figures 1 to 6 As shown, a rotating rod 2 is movably embedded inside the rotary kiln body 1. Multiple stirring blades 201 are fixedly installed on both outer surfaces of the rotating rod 2. A first bevel gear 202 is fixedly sleeved on the outer surface of the rotating rod 2. A motor 203 is installed on the top of the rotary kiln body 1. A sealing element 204 is installed on the outer surface of the output shaft of the motor 203. The sealing element 204 is located on the inner top side of the rotary kiln body 1. A second bevel gear 205 is fixedly installed at the bottom of the output shaft of the motor 203. The second bevel gear 205 meshes with the adjacent first bevel gear 202.

[0035] In this embodiment, personnel can start the motor 203 through the power supply system of the motor 203. When it is running, the output shaft in the seal 204 drives the second bevel gear 205, which in turn drives the first bevel gear 202. When the first bevel gear 202 rotates, the rotating rod 2 drives the stirring blade 201 to rotate, thereby stirring the calcium aluminate powder inside the rotary kiln body 1. Through the structure of the stirring blade 201 and the second bevel gear 205, the calcium aluminate powder can be stirred evenly, preventing uneven material distribution and ensuring that the material inside the rotary kiln body 1 can fully react or mix. This helps to improve product quality and reduce the defect rate in the production process.

[0036] Working principle: During operation, when the rotary kiln body 1 deforms, it compresses the first positioning wheel 104, causing it to move outward. The first positioning wheel 104 then compresses the damper 102 and the first return spring 103 on the support member 101, causing them to contract. Simultaneously, the first positioning wheel 104 compresses the push rod 105, which in turn compresses the movable plate 107, allowing it to slide inside the air cylinder 106. As the movable plate 107 slides, it compresses the air inside the air cylinder 106, forcing it through the air pipe 108 into the first support column 109. Once the air enters the first support column 109, it pushes the second support column 110 with air pressure, causing it to slide inward inside the first support column 109, and simultaneously pulling the second return spring. The spring 111 extends, and the second positioning wheel 112 at the top can be pushed inward by the second support column 110. When the second positioning wheel 112 moves, it will simultaneously pull the positioning column 113 to slide inside the support member 101, so that it can fit more closely to the outer surface of the rotary kiln body 1. Through the structure of the first positioning wheel 104 and the air cylinder 106, the structure can be automatically adjusted when the rotary kiln body 1 deforms, ensuring that the positioning wheel always keeps in contact with the outer surface of the rotary kiln. This avoids unstable operation caused by the deformation of the rotary kiln and ensures the normal operation of the equipment. At the same time, through the cooperation of the support components, the load change caused by the deformation of the outer wall of the rotary kiln body 1 can be effectively reduced, reducing the friction and wear of the rotary kiln body 1 when rotating on the support member 101, and extending the service life of the equipment. During use, personnel can start the motor 203 through its power supply system. When running, the motor 203 is driven by the output shaft in the seal 204 to the second bevel gear 205, which in turn drives the first bevel gear 202. When the first bevel gear 202 rotates, the rotating rod 2 drives the stirring blade 201 to rotate, thereby stirring the calcium aluminate powder inside the rotary kiln body 1. The structure of the stirring blade 201 and the second bevel gear 205 ensures uniform stirring of the calcium aluminate powder, preventing uneven material distribution and ensuring that the material inside the rotary kiln body 1 can fully react or mix. This helps to improve product quality and reduce the defect rate during production.

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.
