[0001] This utility model relates to the field of rotary kilns, specifically to a rotary kiln with enhanced support to reduce losses. Background Technology

[0002] Rotary kilns are widely used in building materials, metallurgy, chemical and environmental protection fields. They are mainly used for high-temperature processing of solid materials. The structure of a rotary kiln includes a cylinder, support device (support rollers), transmission system, sealing device, etc. The kiln body is arranged at an incline and supported by support rollers. It is equipped with a main and auxiliary transmission system to ensure stable operation. Because rotary kilns are heavy, the weight of the rotary kiln presses on the support rollers, which can easily cause damage to the support rollers and requires regular maintenance. Therefore, it is necessary to design a rotary kiln with reinforced support to reduce wear and tear and extend the maintenance cycle. Summary of the Invention

[0003] The purpose of this invention is to provide a rotary kiln with enhanced support and reduced wear, which has the advantage of extending the maintenance cycle.

[0004] The technical solution adopted is as follows:

[0005] A rotary kiln with enhanced support and reduced losses includes a base, a cylinder, and a drive assembly. Two roller supports are mounted on the upper end of the base. An external gear ring and two sets of support rings are coaxially mounted on the side of the cylinder, with the support rings respectively placed on their corresponding roller supports. The drive assembly is equipped with a drive gear that meshes with the external gear ring. Each roller support includes two lower bearing seats, each with a lower support wheel rotatably mounted on it. Horizontal sliding frames are mounted on both sides of the roller support, and telescopic cylinders connected to these horizontal sliding frames are mounted on the roller support. Spring-loaded shock-absorbing mounting seats are installed on the horizontal sliding frames, and side support wheels are rotatably mounted on each of the spring-loaded shock-absorbing mounting seats.

[0006] Preferably, the telescopic cylinder is a hydraulic telescopic cylinder, and a hydraulic station and a hydraulic control system are provided on the base. The hydraulic station is provided with hydraulic pipelines connected to the hydraulic telescopic cylinder.

[0007] Preferably, each of the spring shock absorber mounting bases is equipped with a laser rangefinder, and the base is equipped with a display and a controller electrically connected to the laser rangefinder.

[0008] Preferably, both the lower support wheel and the side support wheel are detachably provided with multiple arc-shaped plates on their outer sides, and the multiple arc-shaped plates are spliced ​​together to form an annular wear layer.

[0009] Preferably, the arc-shaped plate has multiple mounting holes, and the arc-shaped plate is mounted on the lower support wheel and the side support wheel using countersunk bolts.

[0010] Preferably, each of the arc-shaped plates is provided with a wear inspection hole, and the wear inspection hole is provided with a scale.

[0011] Compared to existing technologies, the advantages are:

[0012] 1. This utility model utilizes the lower support wheel and the side support beam to jointly support the cylinder, which not only strengthens the support of the cylinder, but also uses the side support wheel to share the pressure of the lower support wheel, reducing excessive wear of the lower support wheel caused by excessive pressure and extending the maintenance cycle.

[0013] 2. In this utility model, multiple arc-shaped plates can be detachably installed on the outer side of both the lower support wheel and the side support wheel. The multiple arc-shaped plates are spliced ​​together to form a ring-shaped wear layer.

[0021] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 6 As shown:

[0022] Example 1: A rotary kiln with enhanced support and reduced losses includes a base 1, a cylinder 2, and a drive assembly 3. Two roller supports 4 are provided on the upper end of the base 1. An external gear ring 5 and two sets of support rings 6 are coaxially provided on the side of the cylinder 2. The support rings 6 are placed on the corresponding roller supports 4, and the roller supports 4 support the corresponding support rings 6. The drive assembly 3 is provided with a drive gear 7 that meshes with the external gear ring 5. The drive assembly 3 drives the drive gear 7 to rotate. Through the meshing of the drive gear 7 and the external gear ring 5, the cylinder 2 rotates on the roller supports 4 to achieve rotation.

[0023] The roller support frame 4 is U-shaped and includes two lower bearing seats. Each lower bearing seat is rotatably equipped with a lower support wheel 8. The support ring 6 presses on the corresponding lower support wheel 8. Horizontal sliding frames 9 are provided on both sides of the roller support frame 4. Telescopic cylinders 10 are provided on the roller support frame 4 and connected to the horizontal sliding frames 9. The telescopic cylinders 10 drive the corresponding horizontal sliding frames 9 to move, so that the two horizontal sliding frames 9 on the same roller support frame 4 simultaneously approach or move away from the cylinder 2.

[0024] The horizontal sliding frame 9 is equipped with a spring damping mounting base 14. Each spring damping mounting base 14 is rotatably equipped with a side support wheel 15. The side support wheel 15 is installed below the middle of the cylinder 2, and the side support wheel 15 has the same specifications as the lower support wheel 8.

[0025] The lower support wheel 8 and the side support beam jointly support the cylinder 2, which not only strengthens the support of the cylinder 2, but also uses the side support wheel 15 to share the pressure of the lower support wheel 8, reducing excessive wear of the lower support wheel 8 due to excessive pressure and extending the maintenance cycle. When the lower support wheel 8 needs maintenance, the telescopic cylinder 10 controls the two side support wheels 15 to approach the cylinder 2 and lift the cylinder 2 upward to detach it from the lower support wheel 8, making maintenance convenient.

[0026] Example 2: A rotary kiln with enhanced support and reduced losses includes a base 1, a cylinder 2, and a drive assembly 3. Two roller supports 4 are provided on the upper end of the base 1. An external gear ring 5 and two sets of support rings 6 are coaxially provided on the side of the cylinder 2. The support rings 6 are placed on the corresponding roller supports 4, and the roller supports 4 support the corresponding support rings 6. The drive assembly 3 is provided with a drive gear 7 that meshes with the external gear ring 5. The drive assembly 3 drives the drive gear 7 to rotate. Through the meshing of the drive gear 7 and the external gear ring 5, the cylinder 2 rotates on the roller supports 4 to achieve rotation.

[0027] The roller support frame 4 is U-shaped and includes two lower bearing seats. Each lower bearing seat is rotatably equipped with a lower support wheel 8. The support ring 6 presses on the corresponding lower support wheel 8. Horizontal sliding frames 9 are provided on both sides of the roller support frame 4. Telescopic cylinders 10 connected to the horizontal sliding frames 9 are provided on the roller support frame 4. The telescopic cylinders 10 are hydraulic telescopic cylinders. A hydraulic station 11 and a hydraulic control system are provided on the base 1. The hydraulic station 11 is equipped with hydraulic pipelines connected to the hydraulic telescopic cylinders.

[0028] The telescopic cylinder 10 drives the corresponding horizontal sliding frame 9 to move, so that the two horizontal sliding frames 9 on the same support roller frame 4 simultaneously approach or move away from the cylinder 2. Each spring damping mounting base 14 is equipped with a laser rangefinder 12. The base 1 is equipped with a display 13 and a controller connected to it. The laser rangefinder 12 is used to monitor the distance between the horizontal sliding frame 9 and the cylinder 2 and display it on the display 13.

[0029] The horizontal sliding frame 9 is equipped with a spring damping mounting base 14. Each spring damping mounting base 14 is rotatably mounted with a side support wheel 15. The side support wheel 15 is installed below the middle of the cylinder 2. The side support wheel 15 has the same specifications as the lower support wheel 8. Multiple arc-shaped plates 16 are detachably mounted on the outer side of both the lower support wheel 8 and the side support wheel 15. The multiple arc-shaped plates 16 are spliced ​​to form an annular wear layer. Multiple mounting holes 17 are opened on the arc-shaped plates 16. The arc-shaped plates 16 are installed on the lower support wheel 8 and the side support wheel 15 using countersunk bolts. Each arc-shaped plate 16 has a wear inspection hole 18. The wear inspection hole 18 is set with a scale. By checking the scale, the wear condition of the wear layer can be understood. Maintenance is carried out by replacing the wear layer. Compared with replacing the lower support wheel 8 or the side support wheel 15, the cost is lower.

[0030] The working principle is as follows:

[0031] The lower support wheel 8 and the side support beam jointly support the cylinder 2, which not only strengthens the support of the cylinder 2, but also uses the side support wheel 15 to share the pressure of the lower support wheel 8, reducing excessive wear of the lower support wheel 8 due to excessive pressure and extending the maintenance cycle. When the lower support wheel 8 needs maintenance, the telescopic cylinder 10 controls the two side support wheels 15 to approach the cylinder 2 and lift the cylinder 2 upward to detach it from the lower support wheel 8. During maintenance, the arc plate 16 can be replaced by removing the countersunk screws. When maintaining the side support wheel 15, the telescopic cylinder 10 controls the side support wheel 15 to disengage from the cylinder 2, and the arc plate 16 can also be replaced by removing the countersunk screws.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
