Description

Technical Field

[0001] This utility model belongs to the field of rotary kiln technology, specifically relating to a baffle ring for the kiln head and kiln tail of a rotary kiln. Background Technology

[0002] Rotary kilns are widely used in many manufacturing industries such as building materials, metallurgy, chemicals, and environmental protection to mechanically, physically, or chemically process solid materials. A rotary kiln (also known as a rotary calcining kiln) belongs to the building materials equipment category. Currently, during processing, rotary kilns are equipped with baffle rings at the kiln head and tail, with a layer of castable refractory filling the outside of the baffle rings. The presence and properties of this refractory ensure the stability of the baffle rings during actual use.

[0003] Current baffle rings, due to their structure, facilitate the filling of refractory material onto their sides. However, this design presents certain problems in practical use. Specifically, since the baffle rings are directly installed at the kiln head and tail, the refractory material can only protect and fill one side of the baffle ring. After prolonged operation, the other side may crack, affecting the rotary kiln's performance. Utility Model Content

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0021] Depend on Figure 1 , Figure 2 and Figure 3 As shown, this is a schematic diagram of the structure of the baffle ring at the kiln head and kiln tail of the rotary kiln in this embodiment. The baffle ring includes a baffle ring assembly 3, which is installed at the end of the kiln tail section. The kiln tail section is composed of a kiln tail section body 1 and a kiln tail body 2. Both the kiln tail section body 1 and the kiln tail body 2 are tubular structures with openings at the top and bottom. The baffle ring assembly 3 includes a baffle ring body 31 and a casting connection port 32. The baffle ring body 31 is installed on the inner wall of the kiln tail body 2. Multiple sets of casting connection ports 32 are opened on the baffle ring body 31 for communication with the castable material.

[0022] In use, the baffle ring assembly 3 is installed at the end opening of the kiln tail body 2. Then, the baffle ring assembly 3 is completely buried and covered by the filling of the refractory material. The refractory material protects the baffle ring assembly 3 as a whole, preventing it from carbonizing due to high temperature and improving its strength. The opening of the casting connection port 32 allows the refractory material on both sides of the baffle ring body 31 to pass through the casting connection port 32 and connect during the laying of the refractory material, ensuring the integrity of the refractory material casting and improving the service strength of the baffle ring assembly 3.

[0023] From the appendix Figure 3 As shown, the baffle ring body 31 has a 15-25cm hole groove in the middle to facilitate gas flow through the hole groove. The casting connection port 32 is a circular hole groove with a diameter of 2-4cm, and a total of 24 sets of casting connection ports 32 are provided.

[0024] The opening of the groove in the middle of the baffle ring body 31 facilitates the flow of gas, and the establishment of multiple casting connection ports 32 ensures the stable connection of the castable material, thereby enhancing the stability of the connection between the castable material and the baffle ring assembly 3.

[0025] From the appendix Figure 3 and Figure 4 As shown, the overall thickness of the baffle ring body 31 is 2-3cm, and the installation position of the baffle ring body 31 is 15cm away from the opening at the end of the kiln tail body 2.

[0026] The installation position of the retaining ring body 31 during use provides sufficient space for the filling of the refractory material, changing the traditional single-sided pouring method. In addition, the refractory material is connected to the pouring connection port 32, which facilitates the connection of the refractory material on both sides, strengthens the protection of the retaining ring assembly 3 by the refractory material, and prevents the retaining ring assembly 3 from carbonizing due to high temperature on one side.

[0027] From the appendix Figure 2 and Figure 3 As shown, welding parts 4 are installed on both sides of the baffle ring assembly 3. One end of the welding part 4 is connected to the baffle ring body 31, and the other end of the welding part 4 is connected to the inner wall of the kiln tail body 2. The welding part 4 is connected to the baffle ring assembly 3 by welding.

[0028] The installation of the welded component 4 during use enhances the stability of the connection between the baffle ring assembly 3 and the kiln tail body 2. Furthermore, the gap between the welded component 4 and the kiln tail body 2 facilitates the filling of the refractory material into the gap, further ensuring the stability of the baffle ring assembly 3 during use.

[0029] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
