[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Reference Figures 2-4 This utility model provides an embodiment of a thermal shock resistant ceramic filter, comprising a fixed central shaft 1, a plurality of mounting shaft strips 2 fixedly connected to the outer wall of the fixed central shaft 1, two mounting rings 3 fixedly connected to the ends of the plurality of mounting shaft strips 2 away from the fixed central shaft 1, a fixed ring 4 threadedly connected to the outer wall of the two mounting rings 3, an insertion shaft strip 10 disposed on the outer wall of the ceramic filter module 5 and an insertion groove opened on the outer wall of the mounting shaft strip 2, the insertion shaft strip 10 being disposed inside the insertion groove for mounting the ceramic filter module 5, an installation through hole 12 opened on the inner wall of the fixed central shaft 1, a connecting shaft 13 disposed inside the installation through hole 12, a support frame 6 fixedly connected to the outer wall of the fixed central shaft 1 and a plurality of insertion holes 11 opened on the outer wall of the connecting shaft 13, an insertion shaft 7 slidably connected to the middle end of the support frame 6, one end of the insertion shaft 7 being disposed inside one of the insertion holes 11, a spring 9 sleeved on the outer wall of the insertion shaft 7, and a limit ring 8 fixedly connected to the middle end of the insertion shaft 7 for connecting the fixed central shaft 1 and the connecting shaft 13;

[0025] Specifically, when using ceramic filter sheets, if one side of the ceramic filter sheet is damaged, the fixing ring 4 can be rotated to detach it from one of the mounting rings 3. Then, the damaged ceramic filter sheet module 5 can be pulled out from between the two adjacent mounting shafts 2. Next, a new ceramic filter sheet module 5 is inserted into the insertion slots on the adjacent sides of the two mounting shafts 2 via the insertion shaft 10. Finally, the fixing ring 4 is rotated to connect it to the two mounting rings 3, thus fixing the new ceramic filter sheet module 5 between the two adjacent mounting shafts 2 and the two mounting rings 3. This allows for the replacement of the damaged ceramic filter sheet module 5, preventing the entire ceramic filter sheet from being scrapped due to damage to certain areas. When different types of ceramic filter sheets need to be stacked together, the connecting shaft 13 can be inserted into the mounting through hole 12 first, and then the insertion shaft 7 can be inserted into one of the insertion holes 11 on the outer wall of the connecting shaft 13. Then, other types of ceramic filter sheets can be inserted into the outer wall of the connecting shaft 13, thus achieving the stacking of multiple ceramic filter sheets. By changing the insertion position of the insertion shaft 7 into the insertion hole 11, the distance between the stacked ceramic filter sheets can be adjusted, thereby better meeting different usage needs.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The inner circumference of the fixing ring 4 is set on the outer wall of the ceramic filter module 5 on the side away from the fixing central shaft 1. The end of the ceramic filter module 5 away from the fixing central shaft 1 is set on the side close to the two mounting rings 3. One end of the spring 9 is connected to the outer wall of the limiting ring 8, and the other end of the spring 9 is connected to the inner wall of the support frame 6. Two limiting grooves are opened in the inner wall of the mounting through hole 12. Two limiting strips are fixedly connected to the outer wall of the connecting shaft 13. The limiting strips are set inside the limiting grooves. The outer wall of the ceramic filter module 5 is provided with a composite coating.

[0027] Specifically, the ceramic filter module 5 is placed inside the inner circumference of the fixing ring 4 and the two mounting rings 3 to install multiple ceramic filter modules 5. The compression and reset of the spring 9 can allow the insertion shaft 7 and the insertion hole 11 to be inserted and disengaged, thereby installing and fixing the fixed center shaft 1 and the connecting shaft 13. The composite coating on the outer wall of the ceramic filter module 5, which is composed of nano-ceramic particles and organic binder, can play a buffering role during thermal shock and quickly transfer heat away.

[0028] Working principle: When using ceramic filter sheets, if one side of the ceramic filter sheet is damaged, the fixing ring 4 can be rotated to detach it from one of the mounting rings 3. Then, the ceramic filter sheet module 5 in the damaged area can be pulled out from between the two adjacent mounting shafts 2. The new ceramic filter sheet module 5 can then be inserted into the insertion groove on the adjacent side of the two mounting shafts 2 through the insertion shaft 10. The fixing ring 4 can then be rotated to connect it with the two mounting rings 3, thus installing the new ceramic filter sheet module 5 between the two adjacent mounting shafts 2 and the two mounting rings 3. At the same time, the connecting shaft 13 can be inserted into the mounting through hole 12, and the insertion shaft 7 can be inserted into one of the insertion holes 11 on the outer wall of the connecting shaft 13. Other types of ceramic filter sheets can then be inserted into the outer wall of the connecting shaft 13 to stack multiple ceramic filter sheets together. The distance between the stacked ceramic filter sheets can be adjusted by changing the insertion position of the insertion shaft 7 into the insertion hole 11 as needed.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
