Description

Technical Field

[0001] The utility model relates to the technical field of clinker cooling, and particularly relates to a high-temperature clinker cooling device for a dry-process cement kiln. Background Technique

[0002] Cement is a powdery hydraulic inorganic binder. After being stirred with water, it becomes a slurry, which can harden in the air or in water and can firmly cement materials such as sand and stone together. It is generally the cement commonly used in civil engineering. General cement mainly refers to the six categories of cement specified in GB175—2007, namely Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement, and composite Portland cement.

[0003] During the cement production process, it is necessary to quickly cool the calcined raw materials. For example, in the Chinese utility model patent with the patent publication number CN216815061U, it includes a frame, support feet symmetrically distributed on the left and right at the lower end of the frame, a conveying component installed between the frame and another frame for conveying materials, a protective cover installed at the upper end of the frame, and an upper cooling fan fixed inside the upper end of the protective cover to cool the cement clinker. Although this patent can drive the feeding and discharging of cement clinker by the conveying component, the feeding and discharging are more convenient, and continuous uninterrupted cooling operations can be achieved, effectively improving the work efficiency, meeting the large-scale production requirements, blowing air from the upper and lower directions, improving the cooling effect, so that the cement clinker can be cooled faster, and the recycling of the cooling medium can be realized. However, when the cement clinker moves on the conveyor belt, stacking may occur, and the clinker in the middle is difficult to be effectively cooled. Moreover, during the cooling process, the clinker and the conveyor belt are in a relatively static state, and operations such as breaking up the clinker cannot be carried out. In view of this, we have proposed a high-temperature clinker cooling device for a dry-process cement kiln. Content of the Utility Model

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a high-temperature clinker cooling device for a dry-process cement kiln, which can solve the problems of easy stacking and insufficient cooling efficiency caused by the inability to break up the clinker.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A high-temperature clinker cooling device for a dry-process cement kiln, comprising a cooling tank. Three collecting hoppers are fixedly connected to the inner wall of the cooling tank. Three rotating disks are arranged inside the cooling tank. A threaded plate is fixedly connected to the upper surface of the rotating disk. A drive box is arranged inside the cooling tank. A motor is fixedly connected to the bottom wall of the drive box. The output end of the motor is fixedly connected to a drive rod. The upper end of the drive rod rotatably penetrates through the upper surface of the drive box. The upper end of the drive rod is fixedly connected to the lower surface of the uppermost rotating disk. Air outlet boxes are fixedly connected to the lower surfaces of the two lower collecting hoppers. The inside of the air outlet box is hollow. An air outlet is opened on the lower surface of the air outlet box and is communicated with its inside. A feed pipe is arranged on the upper surface of the cooling tank. The lower end of the feed pipe extends into the inside of the cooling tank. An air outlet box identical to the above is sleeved on the outer surface of the feed pipe located inside the cooling tank. An air delivery pipe is arranged on the upper surface of the cooling tank. The other end of the air delivery pipe extends into the inside of the air outlet box.

[0006] Preferably, a support column is fixedly connected to the lower surface of the rotating disk. A rolling ball is movably connected to the lower surface of the support column. The outer surface of the rolling ball contacts the collecting hopper.

[0007] Preferably, a dust-proof cover is arranged on the upper surface of the feed pipe. A handle is fixedly connected to the upper surface of the dust-proof cover.

[0008] Preferably, a discharge pipe is fixedly connected to the lower surface of the lowermost collecting hopper. The diameter of the discharge pipe is 10 cm to 15 cm.

[0009] Preferably, a conical block is fixedly connected to the outer surface of the drive rod. The length of the drive rod is 15 cm to 20 cm.

[0010] Preferably, a dispersion roller is fixedly connected to the upper surface of the conical block. The upper end of the dispersion roller extends into the inside of the discharge pipe.

[0011] Preferably, a support sleeve is sleeved on the outer surface of the cooling tank. An L-shaped connecting rod is fixedly connected to the outer surface of the support sleeve. A support base is fixedly connected to the lower end of the L-shaped connecting rod.

[0012] Preferably, a support rod is fixedly connected to the outer surface of the drive box. The other end of the support rod is fixedly connected to a conical barrel. The upper surface of the conical barrel is fixedly connected to the lower surface of the cooling tank.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] (1) When cooling and reducing the temperature of cement clinker, the dry-process cement kiln high-temperature clinker cooling device conveys the cement clinker into the interior of the cooling tank through the feeding pipe. After the clinker enters the cooling tank, it falls on the threaded plate. Subsequently, the motor drives the driving rod to rotate. After the driving rod rotates, it synchronously drives three rotating disks to rotate synchronously. When the rotating disk rotates, it will synchronously drive the threaded plate to rotate. After the threaded plate rotates, using its arc surface, the clinker is gradually thrown outward. When the clinker moves inside the threaded plate, cold air is provided by an external air cooler, and through the cooperation of the air delivery pipe, the air outlet box and the air outlet, the cold air is transmitted into the threaded plate, thereby cooling and reducing the temperature of the clinker. After the clinker is thrown out, it is collected by the collecting hopper and then falls above the second rotating disk, and then is cooled and reduced in temperature for the second time. Through the above structure, when cooling the cement clinker, it can not only perform multiple coolings, but also use the threaded plate to scatter the piled-up clinker, and simultaneously turn over and disperse the clinker, so that the clinker can be more evenly covered by the cold air, effectively avoiding the problem of slower cooling rate in the middle part.

[0015] (2) When the rotating disk rotates, the dry-process cement kiln high-temperature clinker cooling device can use the rolling ball and the support column to provide it with a certain support, and at the same time use the rolling ball to reduce the friction of its movement. And after the clinker is conveyed, the dust-proof cover can be covered above the feeding pipe to avoid dust from floating out. At the same time, when the driving rod rotates, it will synchronously drive the conical block to rotate, and after the conical block rotates, it will synchronously drive the dispersing roller to rotate. Through the above structure, it can not only avoid dust from floating out through the dust-proof cover, but also avoid the problem that the clinker accumulates in the discharge pipe and cannot be discharged through the dispersing roller, and can effectively support the driving box by means of the cooperation of the support rod and the cone barrel.

The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but it should not be construed as a limitation on the protection scope of the present invention.

[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: a high-temperature clinker cooling device for a dry-process cement kiln, which includes a cooling tank 1. Three collecting hoppers 2 are fixedly connected to the inner wall of the cooling tank 1. Three rotating disks 3 are arranged inside the cooling tank 1. A threaded plate 4 is fixedly connected to the upper surface of the rotating disk 3. A driving box 5 is arranged inside the cooling tank 1. A motor 6 is fixedly connected to the bottom wall of the driving box 5. The output end of the motor 6 is fixedly connected to a driving rod 7. The upper end of the driving rod 7 rotatably penetrates through the upper surface of the driving box 5. The upper end of the driving rod 7 is fixedly connected to the lower surface of the uppermost rotating disk 3. The lower surfaces of the two lower collecting hoppers 2 are both fixedly connected with air outlet boxes 8. The inside of the air outlet box 8 is hollow. The lower surface of the air outlet box 8 is provided with an air outlet 9 communicating with its inside. The upper surface of the cooling tank 1 is provided with a feed pipe 10. The lower end of the feed pipe 10 extends into the inside of the cooling tank 1. The outer surface of the feed pipe 10 located inside the cooling tank 1 is sleeved with an air outlet box 8 identical to the above. The upper surface of the cooling tank 1 is provided with an air delivery pipe 11. The other end of the air delivery pipe 11 extends into the inside of the air outlet box 8. The air delivery pipe 11 can be connected to an external air cooler to provide cold air for cooling. When cooling and lowering the temperature of the cement clinker, the cement clinker is conveyed into the inside of the cooling tank 1 by means of the feed pipe 10. After the clinker enters the cooling tank 1, it falls on the threaded plate 4. Subsequently, the motor 6 is used to drive the driving rod 7 to rotate. After the driving rod 7 rotates, it synchronously drives the three rotating disks 3 to rotate synchronously. When the rotating disk 3 rotates, it will synchronously drive the threaded plate 4 to rotate. After the threaded plate 4 rotates, using its arc surface, the clinker is gradually thrown to the outside. When the clinker moves inside the threaded plate 4, cold air is provided by an external air cooler, and through the cooperation of the air delivery pipe 11, the air outlet box 8 and the air outlet 9, the cold air is transmitted into the threaded plate 4, thereby cooling and lowering the temperature of the clinker. After the clinker is thrown out, it is collected by the collecting hopper 2 and then falls above the second rotating disk 3, and then is cooled and lowered in temperature for the second time. Through the above structure, when cooling the cement clinker, it is not only possible to perform multiple coolings, but also the accumulated clinker can be scattered by means of the threaded plate 4, and the clinker can be turned over and scattered synchronously, so that the clinker can be more evenly covered by the cold air, effectively avoiding the problem of slower cooling rate in the middle part.

[0025] Furthermore, a support column 12 is fixedly connected to the lower surface of the rotating disk 3. A rolling ball 13 is movably connected to the lower surface of the support column 12. The outer surface of the rolling ball 13 contacts the collecting hopper 2. A dust-proof cover 14 is arranged on the upper surface of the feed pipe 10. A handle is fixedly connected to the upper surface of the dust-proof cover 14. A discharge pipe 15 is fixedly connected to the lower surface of the lowermost collecting hopper 2. A conical block 16 is fixedly connected to the outer surface of the driving rod 7. A dispersing roller 17 is fixedly connected to the upper surface of the conical block 16. The upper end of the dispersing roller 17 extends into the interior of the discharge pipe 15. A support sleeve 18 is sleeved on the outer surface of the cooling tank 1. An L-shaped connecting rod 19 is fixedly connected to the outer surface of the support sleeve 18. A support base 20 is fixedly connected to the lower end of the L-shaped connecting rod 19. A support rod 21 is fixedly connected to the outer surface of the driving box 5. The other end of the support rod 21 is fixedly connected to a conical barrel 22. The upper surface of the conical barrel 22 is fixedly connected to the lower surface of the cooling tank 1. When the rotating disk 3 rotates, certain support can be provided by means of the rolling ball 13 and the support column 12, and at the same time, the frictional force of its movement can be reduced by means of the rolling ball 13. And after the clinker is conveyed, the dust-proof cover 14 can be covered above the feed pipe 10 to avoid dust from floating out. At the same time, when the driving rod 7 rotates, the conical block 16 will be driven to rotate synchronously. After the conical block 16 rotates, the dispersing roller 17 will be driven to rotate synchronously. Through the above structure, not only can the dust-proof cover 14 be used to prevent dust from floating out, but also the dispersing roller 17 can be used to prevent the clinker from accumulating in the discharge pipe 15, resulting in the problem of being unable to discharge, and the driving box 5 can be effectively supported by the cooperation of the support rod 21 and the conical barrel 22.

[0026] Working principle: When cooling and reducing the temperature of the cement clinker, the cement clinker is conveyed into the interior of the cooling tank 1 through the feed pipe 10. After the clinker enters the cooling tank 1, it falls on the threaded plate 4. Then, the motor 6 is used to drive the driving rod 7 to rotate. After the driving rod 7 rotates, the three rotating disks 3 are driven to rotate synchronously. When the rotating disk 3 rotates, the threaded plate 4 will be driven to rotate synchronously. After the threaded plate 4 rotates, the clinker is gradually thrown to the outside by using its arc surface. When the clinker moves in the threaded plate 4, cold air is provided by an external cold air blower, and the cold air is transmitted into the threaded plate 4 through the cooperation of the air delivery pipe 11, the air outlet box 8 and the air outlet 9, so as to cool and reduce the temperature of the clinker. After the clinker is thrown out, it is collected by the collecting hopper 2, and then falls above the second rotating disk 3, and then is cooled and reduced in temperature for the second time. When the rotating disk 3 rotates, certain support can be provided by means of the rolling ball 13 and the support column 12, and at the same time, the frictional force of its movement can be reduced by means of the rolling ball 13. And after the clinker is conveyed, the dust-proof cover 14 can be covered above the feed pipe 10 to avoid dust from floating out. At the same time, when the driving rod 7 rotates, the conical block 16 will be driven to rotate synchronously. After the conical block 16 rotates, the dispersing roller 17 will be driven to rotate synchronously.
