Description

Technical Field

[0001] The utility model belongs to the technical field of air preheaters, and particularly relates to an air preheater with an installation and positioning structure. Background Art

[0002] The air preheater mainly provides a flue gas passage, which is conducive to heat exchange, etc. The air preheater is a device that uses the heat of boiler flue gas to heat air. According to different heat transfer methods, the air preheater can be divided into two types: heat transfer type and regenerative type. The air preheater generally consists of three parts: a box body, a heat tube bundle, and an intermediate partition.

[0003] The existing air preheaters on the market have the following problems in actual use:

[0004] 1. When the traditional air preheater is actually used, since pipes need to be installed on the flange of the air preheater, at this time, the pipes need to be aligned with the flange of the air preheater. The traditional air preheater does not have a positioning device during installation, so at this time, only manual alignment of the installation position and the flange of the air preheater can be carried out, which is rather troublesome to use.

[0005] 2. During the use of most air preheaters, since the pipes on both sides of the air preheater are exposed outside, when the air preheater is in use and is collided on both sides, it may cause damage to the pipes at this time, resulting in deformation of the pipes, and the protection during use is poor. Content of the Utility Model

[0006] The purpose of the utility model is to provide an air preheater with an installation and positioning structure to solve the technical problems raised in the background art.

[0007] To achieve the above purpose, the specific technical solution of the utility model is as follows: An air preheater with an installation and positioning structure includes an air preheater body. A fixed frame is sleeved on the surface of the air preheater body. A side plate is welded to the back of the fixed frame. A second external threaded rod is welded to the surface of the side plate.

[0029] To better understand the purpose, structure and function of the present utility model, the air preheater with an installation and positioning structure of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] As Figures 1-6 shown, an air preheater with an installation and positioning structure of the present utility model includes an air preheater body 1. A fixing frame 3 is sleeved and fixed on the surface of the air preheater body 1. A side plate 4 is welded to the back of the fixing frame 3. A second external threaded rod 9 is welded to the surface of the side plate 4. A fixing plate 7 is installed on the surface of the side plate 4. The second external threaded rod 9 passes through the fixing plate 7. A second nut 10 is installed on the surface of the second external threaded rod 9. By installing the second external threaded rod 9, the second external threaded rod 9 passes through the fixing plate 7, and the second nut 10 is installed on the surface of the second external threaded rod 9. At this time, the fixing plate 7 can be fixed on the side plate 4, thereby providing an installation and fixing effect for the positioning frame 8, which is very convenient to use. One end of the second nut 10 abuts against the fixing plate 7. The positioning frame 8 is welded to the surface of the fixing plate 7. A flange 2 is welded to one end of the air preheater body 1. The inside of the positioning frame 8 abuts against the surface of the flange 2. By installing the positioning frame 8, when installing other devices on the flange 2, the positioning frame 8 can provide a positioning effect for the flange 2. The device to be installed can be moved towards the position of the flange 2 by fitting the inner wall of the positioning frame 8, which is very convenient to use.

[0031] The surface of the air preheater body 1 is welded and fixedly connected with an internal thread seat 12. A fixing rod 16 is sleeved and fixed inside the internal thread seat 12. External threads are provided on the surface of the fixing rod 16. A bearing 14 is welded to the other end of the fixing rod 16. A retaining bar 13 is welded to the surface of the bearing 14. The retaining bars 13 are arranged in an equidistant distribution. By installing the retaining bars 13, the retaining bars 13 can protect the pipes exposed on both sides of the air preheater body 1, so that the pipes will not be collided by larger objects, and the protection performance is strong during use.

[0032] A first external threaded rod 5 is welded to the surface of the fixing frame 3. The first external threaded rod 5 penetrates through the flange 2. The first external threaded rods 5 are arranged in an equidistant distribution. A first nut 6 is sleeved on the surface of the first external threaded rod 5. By installing the first external threaded rod 5, when it is necessary to fix the device installed on the flange 2, the fixing frame 3 can be directly moved. The first external threaded rod 5 driven by the fixing frame 3 directly penetrates through the flange 2 and the installed device, and then the first nut 6 is installed on the first external threaded rod 5 to fix it. At this time, there is no need to install bolts one by one, which is very convenient during use.

[0033] A turntable 15 is welded to the surface of the fixing rod 16. The turntables 15 and the internal thread seats 12 are symmetrically distributed. The fixing rods 16 are symmetrically distributed. By installing the turntable 15, when it is necessary to rotate the fixing rod 16, the turntable 15 can be used to drive the fixing rod 16 to rotate, providing a force application point for the fixing rod 16, which is very convenient during use.

[0034] A clamping block 11 is welded to the surface of the side plate 4. A clamping groove 17 is provided on the surface of the fixing plate 7. The clamping block 11 is embedded inside the clamping groove 17. The clamping blocks 11 are symmetrically distributed. By installing the clamping blocks 11 and the clamping grooves 17, when installing the fixing plate 7, the clamping blocks 11 can be embedded inside the clamping grooves 17 to provide a positioning effect for the fixing plate 7, making it more convenient to install the fixing plate 7 subsequently.

[0035] The fixing plates 7 are symmetrically distributed. The side plates 4 are symmetrically distributed. By the distribution forms of the installation of the fixing plates 7 and the side plates 4, after the positioning frame 8 is installed by using the fixing plates 7 and the side plates 4, the stability of the positioning frame 8 can be further improved, and the stability is strong during use.

[0036] Working principle of the air preheater with an installation and positioning structure: When using the air preheater with an installation and positioning structure, the fixing plate 7 should be installed on the side plate 4 first. At this time, the clamping block 11 on the side plate 4 can be embedded into the clamping groove 17 of the side plate 4. Subsequently, the second nut 10 is installed on the surface of the second external threaded rod 9 to fix the fixing plate 7, and then the positioning frame 8 is installed and fixed. Then, the stop bar 13 is installed on the surface of the air preheater body 1. At this time, the rotatable effect provided by the bearing 14 for the fixing rod 16 can be utilized to rotate the fixing rod 16, so that the fixing rod 16 is embedded into the internal threaded seat 12 to install the stop bar 13. Subsequently, the air preheater with an installation and positioning structure can be used. When in use, other matching devices need to be installed on the flange 2. At this time, the positioning frame 8 can be utilized to provide a positioning effect for the flange 2. The device to be installed can be moved towards the flange 2 by fitting along the inner wall of the positioning frame 8, which is very convenient in use. And during the use process, the stop bar 13 can be utilized to protect the pipes exposed on both sides of the air preheater body 1, so that the pipes will not be collided by larger objects, and the protection performance is strong during use.
