Description

Technical Field

[0001] This utility model relates to the field of rotary kiln technology, specifically to a rotary kiln tail static friction plate sealing device. Background Technology

[0002] A rotary kiln is a piece of equipment used for firing materials. It is widely used in industries such as cement, metallurgy, chemical, and building materials. Its main function is to process raw materials at high temperatures and transform them into finished products. During the operation of a rotary kiln, a sealing device is installed to ensure the sealing effect of the kiln tail. The sealing of the kiln tail is achieved by the contact between the static friction disc and the dynamic friction disc. In the actual sealing process of the sealing device through the static friction disc and the dynamic friction disc, relying solely on the contact and sealing between the static friction disc and the dynamic friction disc will result in air and material leakage. At the same time, during the operation of the rotary kiln, fly ash and material particles can easily seep in from the edge of the main friction surface. The seeping particles will increase the wear of the static friction disc and the dynamic friction disc, and reduce the service life of the sealing device.

[0003] In summary, there is a current need for a rotary kiln tail sealing device that can block fly ash and material particles. Utility Model Content

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0015] To address the technical problems in the background section, the following rotary kiln tail static friction plate sealing device is provided: Combination Figures 1-4 As shown, the present invention provides a rotary kiln tail static friction plate sealing device, including a kiln tail body 1 and a rotary kiln cylinder 3. A connecting cylinder 2 is provided between the kiln tail body 1 and the rotary kiln cylinder 3. An assembly ring 31 is provided on the outer side of the rotary kiln cylinder 3. A static friction disc 5 is provided on the side of the assembly ring 31. A dynamic friction component 4 is provided on the side of the kiln tail body 1. A windproof sealing component 6 and a dustproof and guide component 7 are provided on the outer side of the static friction disc 5. The sealing component 6 includes a mounting ring seat 61, a sealing cloth 62, and a steel wire rope 63. An installation groove is opened on the outer side of the mounting ring seat 61. The installation groove is arc-shaped and the sealing cloth is provided in the installation groove. 62. A steel wire rope 63 is provided on the outside of the sealing cloth 62. The installation groove and the steel wire rope 63 can fix the sealing cloth 62 to the outside of the static friction disc 5. The sealing cloth 62 is a high silica fiber cloth. The sealing cloth 62 is located at the joint between the dynamic friction disc 43 and the static friction disc 5. In this way, the kiln tail body 1 and the static friction disc 5 can form a floating connection. The sealing cloth 62 located at the joint between the dynamic friction disc 43 and the static friction disc 5 can effectively reduce the air leakage of the static friction disc 5, reduce the formation of skin due to air leakage, reduce the system ventilation resistance, and reduce heat consumption. While ensuring the normal movement of the static friction disc 5 and the dynamic friction disc 43, it can also play a good sealing role. As an improvement to the above solution, the sealing cloth 62 has multiple layers, and the multiple layers of sealing cloth 62 are bonded to each other and tightly bonded. The multiple layers of sealing cloth 62 can further improve the sealing effect through staggered seams. At the same time, the multiple layers of sealing cloth 62 have a longer service life. In this embodiment, a fixing plate 64 is provided on the outer side of the mounting ring seat 61. The bottom surface of the fixing plate 64 contacts the edge of the sealing cloth 62. The fixing plate 64 is bolted to the mounting ring seat 61. The fixing plate 64 cooperates with the mounting ring seat to fix and clamp the sealing cloth 62, thereby improving the sealing stability of the sealing cloth 62. In this embodiment, the dynamic friction assembly 4 includes a cylinder 41, a connecting ring 42, and a dynamic friction disc 43. The cylinder 41 is arranged in a ring around the outside of the kiln tail body 1. The end of the cylinder 41 is provided with a connecting ring 42. The inner side of the connecting ring 42 is provided with a dynamic friction disc 43. The dynamic friction disc 43 is in close contact with the side of the static friction disc 5. The dynamic friction disc 43 cooperates with the static friction disc 5 to achieve the sealing of the kiln tail body 1. The cylinder 41 can maintain the contact effect of the dynamic friction disc 43.

[0016] When the rotary kiln tail static friction plate sealing device is used, the multi-layer sealing cloth 62 is tightly fixed to the joint between the moving friction plate 43 and the static friction plate 5 by the steel wire rope 63 and the fixed pressure plate 64. Under the floating connection between the multi-layer sealing cloth 62 and the moving friction plate 43, the phenomenon of air leakage at the joint can be reduced, ensuring the sealing effect between the moving friction plate 43 and the static friction plate 5 while improving the sealing effect. Example 2

[0017] like Figures 1-4 As shown, based on the above embodiments, this embodiment further provides the following: To ensure that the sealing assembly 6 maintains a good sealing effect, this embodiment provides the following design: The protective component 7 includes a mounting annular seat 71, a mounting annular plate 72, and a dustproof guide hood 73. The mounting annular seat 71 is fixedly mounted on the outside of the static friction disc 5. The mounting annular seat 71 has a mounting annular plate 72 on its top. The mounting annular plate 72 is bolted to the mounting annular seat 71. The mounting annular plate 72 has a dustproof guide hood 73 on its side. The dustproof guide hood 73 has an arc-shaped structure. The arc-shaped dustproof guide hood 73 can block external dust, prevent dust from accumulating at the corners, prevent dust from directly washing over the sealing cloth 62, and reduce the wear rate of the sealing cloth 62. In this embodiment, an air supply pipe 74 is provided inside the mounting annular seat 71. One end of the air supply pipe 74 is provided with an air inlet 75. The end of the air supply pipe 74 away from the air inlet 75 is connected through the mounting annular seat 61. The air outlet of the air supply pipe 74 is located inside the sealing cloth 62. Through the air supply pipe 74 provided inside the mounting annular seat, air can be sent into the inside of the sealing cloth 62. After the air enters the inside of the sealing cloth 62, it will flow out from the connection between the sealing cloth 62 and the dynamic friction disc 43, thereby achieving the effect of unblocking the sealing cloth 62.

[0018] During the use of the sealing cloth 62, the dustproof guide 73 in the protective component 7 can protect the sealing cloth 62 from dust, prevent dust accumulation, and avoid dust directly washing over the sealing cloth 62, thereby improving the sealing effect and service life of the sealing cloth 62. Then, the air supply pipe 74 in the installation ring seat 2 71 can be connected to the external air supply equipment to send air into the inside of the sealing cloth 62. Through the flow of air, the edges of the sealing cloth 62 can be cleared, preventing the accumulation of dust particles and other debris that increase the wear of the sealing cloth 62, thus helping to maintain the sealing effect of the sealing cloth 62.
