[0028] The embodiment of the utility model relates to an expansion indicator of an air distribution plate of an incinerator, such as Figure 1 , Figure 2 and Figure 3 As shown, including:
[0029] The incinerator air distribution plate 1 of this embodiment is placed in the incinerator;
[0030] A plurality of indicator fixing devices 10 are arranged on the circumference of the incinerator air distribution plate 1; the indicator fixing devices 10 are used to fix the indicator 20;
[0031] An indicator 20 is arranged in any one of the indicator fixing devices; the indicator 20 is used to indicate the expansion condition of the air distribution plate of the incinerator;
[0032] One end of the indicator 20 is arranged along the bottom of the incinerator air distribution plate 1; the indicator 20 extends from the edge of the incinerator air distribution plate 1 along the bottom of the incinerator air distribution plate 1 to the outside of the incinerator 2; the indicator 20 indicates the expansion condition of the incinerator air distribution plate 1. By arranging the indicator 20 on the incinerator air distribution plate 1, it is possible to directly monitor whether the thermal expansion of the incinerator air distribution plate 1 is normal on the outside of the incinerator 2 during operation; during operation, it is also possible to judge whether the sand bed of the incinerator is blocked or has poor fluidization by the expansion of the incinerator air distribution plate 1, thereby solving the problem in the prior art that if the sand bed of the incinerator is blocked or has poor fluidization during operation, the existing incinerator air distribution plate is heated unevenly. Since the existing incinerator air distribution plate 1 is too large in size and the temperature difference between the upper and lower sides of the incinerator air distribution plate 1 is too large, it is in a positive pressure zone during operation, and the incinerator air distribution plate is inside the incinerator, it is impossible for personnel to effectively monitor the uniformity of the thermal expansion of the incinerator air distribution plate 1 during operation, which leads to deformation and cracking of the rib plate of the incinerator air distribution plate 1. Once the incinerator air distribution plate is deformed and cracked, it needs to be shut down for maintenance, which seriously affects production and causes huge economic losses. Technical problems.
[0033] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the incinerator air distribution plate 1 is a circular structure; the incinerator air distribution plate 1 is placed on a bracket 3 welded to the inner wall of the incinerator 2, so that the incinerator air distribution plate 1 and the bracket 3 are movably connected, and the incinerator air distribution plate 1 can expand outward when expanding.
[0034] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a plurality of hoods 4 are evenly fixed in a concentric circle manner on the incinerator air distribution plate 1. The hoods 4 are mainly used to evenly distribute the hot air.
[0035] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, an annular reinforcing rib 5 with the center of the incinerator air distribution plate as a concentric circle is welded below the incinerator air distribution plate 1. The annular reinforcing rib 5 is to prevent the incinerator air distribution plate 1 from cracking and play a reinforcing role.
[0036] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the incinerator air distribution plate 1 is placed inside the incinerator 2.
[0037] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the indicator fixing device 10 further includes:
[0038] On one side of the incinerator air distribution plate 1, a sealing sleeve 11 is fixed on the furnace wall of the incinerator 2; the sealing sleeve 11 is mainly used to place a high temperature resistant filler 12,
[0039] A high temperature resistant filler 12 is placed in the sealing sleeve 11. The high temperature resistant filler 12 is mainly used to prevent the rigid pointer 21 from being affected by heat, thereby causing the rigid pointer 21 to deform, and reduce the error when indicating the expansion of the incinerator air distribution plate 1; the high temperature resistant filler 12 can ensure accurate readings and meet the sealing requirements of the positive pressure area.
[0040] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the indicator 20 further includes:
[0041] One end of the rigid pointer 21 is inserted into the middle of the high-temperature resistant filler 12 of the indicator fixing device 10 and fixedly connected to the side of the incinerator air distribution plate 1, and the rigid pointer 21 is led out to the outside of the furnace wall of the incinerator 2; when the incinerator air distribution plate 1 expands, the expansion change of the incinerator air distribution plate 1 can be intuitively seen through the up, down, left and right position changes of the rigid pointer 21.
[0042] An indicator plate bracket 22 is welded on the outer side of the furnace wall of the incinerator 2; the indicator plate bracket 22 is used to fix the indicator plate 23;
[0043] An indicator plate 23 is welded on the indicator plate bracket 22. The indicator plate 23 can visually show the expansion change of the incinerator air distribution plate 1.
[0044] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, scale lines in millimeters are respectively arranged on the indicator plate 23 in the horizontal direction and the vertical direction.
[0045] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, there are four indicator fixing devices 10 and four indicators 20 .
[0046] In order to achieve the above technical effects, in the incinerator air distribution plate expansion indicator of this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the indicator fixing device 10 and the indicator 20 are respectively arranged in the directions of 0°, 90°, 180° and 270° of the air distribution plate of the incinerator. In this way, the expansion change of the air distribution plate 1 of the incinerator can be more intuitively seen. In this way, during operation, on the outside of the incinerator 2, it is possible to directly monitor whether the thermal expansion of the incinerator air distribution plate 1 is normal; during operation, the expansion of the incinerator air distribution plate 1 can also be used to determine whether the incinerator sand bed is blocked or has poor fluidization, thereby solving the problem in the prior art that if the incinerator sand bed is blocked or has poor fluidization during operation, the existing incinerator air distribution plate 1 will be heated unevenly. Since the existing incinerator air distribution plate 1 is too large and the temperature difference between the upper and lower sides of the incinerator air distribution plate 1 is too large, it is in a positive pressure zone during operation, and the incinerator air distribution plate 1 is inside the incinerator, it is impossible for personnel to effectively monitor the uniformity of the thermal expansion of the incinerator air distribution plate 1 during operation, which leads to deformation and cracking of the rib plate of the incinerator air distribution plate 1. Once the incinerator air distribution plate 1 is deformed and cracked, it needs to be shut down for maintenance, which seriously affects production and causes huge economic losses. Technical problems.
