Description

Technical Field

[0001] The utility model relates to the technical field of installation tools, in particular to an adjusting tool for the sealing piece of an air preheater. Background Art

[0002] The boiler is equipped with two three-compartment full-mode structure rotary air preheaters (hereinafter referred to as air preheaters). The air preheater is a heat exchange device that uses the heat of the flue gas at the tail of the boiler to heat the combustion air. Driven by the center, the rotor of the air preheater mainly consists of 48 fan-shaped bins and a rotor center cylinder. Sealing pieces are installed along the edges of each rotor partition and fan-shaped bin. During the shutdown of the unit, the sealing pieces of the air preheater need to be inspected. If the gap is found to be too large or worn, adjustment or replacement is required. Measuring the gap and adjusting the gap for each sealing piece takes a long time and has low efficiency, which directly affects the startup of the unit. Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the utility model provides an adjusting tool for the sealing piece of an air preheater. To achieve the above purpose, the utility model adopts the following technical solutions:

[0004] An adjusting tool for the sealing piece of an air preheater is used to position and install the sealing piece at the connection between the fan-shaped bins of the air preheater. The air preheater includes a central rotating cylinder, a fixed frame supporting the central rotating cylinder, a number of fan-shaped bins assembled into a circle, and a bracket supporting the fan-shaped bins. It includes a cross bar and two vertical bars. The length of the cross bar corresponds to the width of the corresponding fan-shaped bin. The vertical bars are fixedly connected to both ends of the cross bar, and the vertical bars are detachably connected to the fixed frame.

[0005] Furthermore, a number of connection holes are evenly opened on the fixed frame. Through holes corresponding to the connection holes are opened at the bottom of the vertical bar, and bolts are arranged in the through holes and the connection holes.

[0006] Furthermore, a triangular column foot is fixedly connected to the bottom end of the vertical bar, and the column foot is flush with the top surface of the fixed frame.

[0007] Furthermore, indicating rods are hinged to both ends of the cross bar, and stoppers are fixedly connected to both ends of the cross bar. The stoppers are used to limit the indicating rods to be vertical.

[0008] Furthermore, scales are arranged on the top of the cross bar.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. By using the tool provided in this application, the position of the sealing piece can be quickly located and adjusted, significantly shortening the time required for measuring and adjusting the gap for each sealing piece;

[0011] 2. The usage method of this tool is simple and intuitive. Accurate positioning and adjustment can be achieved without complex calibration steps, reducing the operation difficulty and human error.

[0012] 3. Since the length of the cross bar matches the width of the corresponding sector bin, and the vertical bar can be stably connected to the fixed frame, it can ensure that the sealing piece is in the correct position during the adjustment process, thus guaranteeing good sealing performance.

[0017] The following further describes the technical solutions in the present utility model in conjunction with the drawings and embodiments.

[0018] Please refer to Figure 1 、 Figure 2 As shown, an air preheater sealing piece adjustment tool is used to position and install the sealing piece 2 at the connection between the sector bins 1 of the air preheater. The air preheater includes a central rotating cylinder 3, a fixed frame 4 supporting the central rotating cylinder 3, several sector bins 1 assembled into a circle, and a bracket supporting the sector bins 1. It includes a cross bar 5 and two vertical bars 6. The length of the cross bar 5 corresponds to the width of the corresponding sector bin 1. The vertical bars 6 are fixedly connected to both ends of the cross bar 5, and the vertical bars 6 are detachably connected to the fixed frame 4.

[0019] Working principle: When using this tool, align the cross bar 5 with the sector bin 1 and fix it on the fixed frame 4 through the vertical bars 6. Use this as a guide to accurately adjust and install the position and gap of the sealing piece 2. Moreover, fix the tool on a fixed frame 4 and rotate the sector bin 1 to adjust and install the next sealing piece 2 relying on this tool.

[0020] In this embodiment, please refer to Figure 2 As shown, a plurality of connection holes 7 are evenly opened on the fixed frame 4. Through holes corresponding to the connection holes 7 are opened at the bottom of the vertical bar 6, and bolts are provided in the through holes and the connection holes 7. When the equipment is out of use, installing this tool on the fixed frame 4 does not affect the normal use of the air preheater.

[0021] In this embodiment, please refer to Figure 2 As shown, a triangular base 8 is fixedly connected to the bottom end of the vertical rod 6, and the base 8 is flush with the top surface of the fixing frame 4. Using the base 8 facilitates accurately determining the position of the fixing frame 4 to improve the position accuracy of the cross bar 5, thereby accurately adjusting the position of the sealing piece 2.

[0022] In this embodiment, please refer to Figure 2 As shown, indicating rods 9 are hinged to both ends of the cross bar 5, and stoppers are fixedly connected to both ends of the cross bar 5. The stoppers are used to limit the indicating rods 9 to be vertical. When not in use, the indicating rods 9 are rotated below the cross bar 5. When in use, the indicating rods 9 are rotated above the cross bar 5 to shorten the distance between the cross bar 5 and the sealing piece 2, so as to accurately adjust the position of the sealing piece 2.

[0023] In this embodiment, scales are provided on the top of the cross bar 5. It is convenient to adjust the distance of the sealing piece 2 with reference to the scales, and it is easy to use.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
