Description

Technical Field

[0001] This invention relates to a method for installing and correcting the heat exchange mechanism inside a heat exchange tank. Background Technology

[0002] Heat exchange tanks are commonly used in industrial production. A heat exchange tank consists of a tank body and a heat exchange mechanism. The heat exchange mechanism generally consists of a mounting plate and heat exchange tubes mounted on the mounting plate. When manufacturing a heat exchange tank, the tank body is usually made at one station and the heat exchange mechanism is made at another station. After the heat exchange mechanism and the tank body are manufactured, the heat exchange mechanism needs to be installed in the tank body. Since the tank body and the heat exchange mechanism can weigh several tons or even tens of tons and have a large volume, it is difficult to align and install the heat exchange mechanism. Summary of the Invention

[0003] This invention proposes a method for installing and correcting a heat exchange mechanism inside a heat exchange tank. The method includes a tank body extending through the tank from front to back, and a heat exchange mechanism. The heat exchange mechanism is equipped with multiple heat exchange mounting plates, the maximum diameter of which is equal to the inner diameter of the tank body. Each heat exchange mounting plate has multiple heat exchange mounting holes, and connecting pipes are installed in these holes to connect the multiple heat exchange mounting plates together in series. The method for moving the heat exchange mounting plates into the tank body is as follows:

[0004] S1. The heat exchange mechanism is horizontally set on the moving platform, and the horizontal height of the lowest point of the heat exchange mechanism is the same as the horizontal height of the lowest point of the inner wall of the tank. The moving platform extends to or is close to the tank inlet. The moving platform is equipped with multiple rollers to facilitate the movement of the heat exchange mechanism toward the tank.

[0005] S2. A positioning plate is provided at the rear end of the tank body. The positioning plate is provided with a plurality of connection mounting holes. The positions of the connection mounting holes correspond to the positions of the heat exchange mounting holes. At least three non-collinear first positioning cylinders are provided on the heat exchange mounting plate at the front end. At least three non-collinear second positioning cylinders are provided on the heat exchange mounting plate at the rear end. At least three non-collinear third positioning cylinders are provided on the connection mounting holes. The positions of the first positioning cylinders, second positioning cylinders and third positioning cylinders correspond.

[0006] S3. The positioning line extends from the first positioning cylinder and passes through the second and third positioning cylinders in sequence before connecting to the automatic winding mechanism. When winding the line, the automatic winding mechanism pulls the heat exchange mechanism towards the rear end of the tank through the positioning line. As the positions get closer, the second and third positioning cylinders overlap.

[0007] As the automatic winding mechanism gradually shortens the positioning line, the second and third positioning cylinders gradually approach and correspond to each other. Since at least three non-collinear first positioning cylinders are provided on the heat exchange mounting plate at the front end, at least three non-collinear second positioning cylinders are provided on the heat exchange mounting plate at the rear end, and at least three non-collinear third positioning cylinders are provided on the connecting mounting hole, the non-collinearity of the three points can achieve the correspondence between the heat exchange mounting plate at the rear end and the positioning plate. When the winding is completed, the second and third positioning cylinders coincide, realizing the installation and correction of the heat exchange mechanism.

[0008] In one or more embodiments, a drive plate is provided at one end of the positioning line, the drive plate abuts against the front end of the first positioning cylinder, and the diameter of the drive plate is larger than the diameter of the first positioning cylinder.

[0009] In one or more embodiments, the drive board is integrated with the positioning line.

[0010] In one or more embodiments, the third positioning cylinder is provided with a positioning cavity, the positioning cavity is conical, and the front end diameter of the positioning cavity is larger than the rear end diameter of the positioning cavity.

[0011] In one or more embodiments, the automatic take-up mechanism is provided with a take-up reel and a drive motor, the drive motor driving the take-up reel to move.

[0012] In one or more embodiments, the lengths of the multiple positioning lines are the same, the speeds of the multiple drive motors are the same, and the drive motors are equipped with potentiometers. When the drive motors start, the multiple drive motors first reverse to their initial positions and then simultaneously rotate forward to achieve synchronous wire winding. This avoids the problem of different wire winding positions caused by different positions of the drive motors, ensuring synchronous wire winding and guaranteeing that the heat exchange mechanism can be installed in place.

[0013] The beneficial effects of this invention are as follows: By setting three non-collinear first positioning cylinders on the frontmost heat exchange mounting plate, three non-collinear second positioning cylinders on the rearmost heat exchange mounting plate, and three non-collinear third positioning cylinders on the positioning plate, and by connecting the first, second, and third positioning cylinders in series through positioning lines and driving the heat exchange mechanism to enter the tank, as the first and second positioning cylinders approach the third positioning cylinder, the radial projections of the first, second, and third positioning cylinders overlap, thus realizing the installation and correction of the heat exchange mechanism and solving the problem of heat exchange structure installation and correction in large heat exchange tanks.

[0020] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0021] See appendix Figure 1-6 A method for installing and correcting a heat exchange mechanism inside a heat exchange tank includes a tank body 1 and a heat exchange mechanism 2 that run through the tank from front to back. The heat exchange mechanism 2 is provided with multiple heat exchange mounting plates 21, the maximum diameter of which is equal to the inner diameter of the tank body 1. Multiple heat exchange mounting holes 23 are provided on each heat exchange mounting plate 21, and connecting pipes 22 are provided on each heat exchange mounting hole 23 to connect the multiple heat exchange mounting plates 21 together in series. The method for moving the heat exchange mounting plates 21 to the tank body 1 is as follows:

[0022] S1. The heat exchange mechanism 2 is horizontally set on the moving platform 3. The horizontal height of the lowest point of the heat exchange mechanism 2 is the same as the horizontal height of the lowest point of the inner wall of the tank 1. The moving platform 3 extends to or is close to the inlet end of the tank 1. The moving platform 3 is provided with multiple rollers 31 to facilitate the movement of the heat exchange mechanism 2 toward the tank 1.

[0023] S2. A positioning plate 11 is provided at the rear end of the tank body 1. The positioning plate 11 is provided with a plurality of connection mounting holes 12. The positions of the connection mounting holes 12 correspond to the positions of the heat exchange mounting holes 22. At least three non-collinear first positioning cylinders 24 are provided on the frontmost heat exchange mounting plate 21. At least three non-collinear second positioning cylinders 25 are provided on the rearmost heat exchange mounting plate 21. At least three non-collinear third positioning cylinders 13 are provided on the connection mounting holes 12. The positions of the first positioning cylinders 24, second positioning cylinders 25 and third positioning cylinders 13 correspond.

[0024] S3. The positioning line extends from the first positioning cylinder 24 and passes through the second positioning cylinder 25 and the third positioning cylinder 13 in sequence before connecting to the automatic winding mechanism 4. When winding the line, the automatic winding mechanism 4 pulls the heat exchange mechanism 2 toward the rear end of the tank body 1 through the positioning line 5. As the positions get closer, the second positioning cylinder 25 and the third positioning cylinder 13 overlap.

[0025] Furthermore, a drive plate 51 is provided at one end of the positioning line 5, the drive plate 51 abuts against the front end of the first positioning cylinder 24, and the diameter of the drive plate 51 is larger than the diameter of the first positioning cylinder 24.

[0026] Furthermore, the drive board 51 is integrated with the positioning line 5.

[0027] Furthermore, the third positioning cylinder 13 is provided with a positioning cavity, which is cone-shaped, and the front end diameter of the positioning cavity is larger than the rear end diameter of the positioning cavity.

[0028] Furthermore, the automatic take-up mechanism 4 is provided with a take-up reel 42 and a drive motor 41. The drive motor 41 drives the take-up reel 42 to move. The center diameter of the take-up reel 42 is smaller than the diameters of its two sides.

[0029] Furthermore, the lengths of the multiple positioning lines 5 are consistent, and the rotation speeds of the multiple drive motors 41 are consistent. Each drive motor 41 is equipped with a potentiometer. When the drive motor 41 starts, the multiple drive motors 41 first reverse to their initial positions and then simultaneously rotate forward to achieve synchronous line take-up.
