[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Refer to the attached Figure 1-Figure 5A shell and tube water solidification heat exchanger includes a heat exchanger body 1, which includes a tube shell 11, and also includes a first end plate 12 and a second end plate 13 on both sides of the tube shell 11. A tube bundle 2 fixed between the first end plate 12 and the second end plate 13 is provided in the tube shell 11, and a cleaning mechanism 3 for removing dirt is installed in the tube shell 11. The cleaning mechanism 3 includes a cleaning plate 31 that moves along the forward direction of the inner wall of the tube shell 11, and also includes a threaded rod 32 rotatably installed between the first end plate 12 and the second end plate 13. The tube bundle 2 passes through the cleaning plate 31 and the threaded rod 32, and the cleaning plate 31 is threadedly installed on the threaded rod 32.

[0019] Specifically, a plurality of cleaning sleeves 36 are fixedly mounted on the cleaning plate 31 , the tube bundle 2 passes through the cleaning sleeves 36 , the cleaning sleeves 36 are in contact with the outer wall of the tube bundle 2 , and a cleaning ring 37 is fixedly mounted on the cleaning plate 31 , the cleaning ring 37 is in contact with the inner wall of the tube shell 11 .

[0020] It should be noted that a guide rod 38 is fixedly installed between both sides of the first end plate 12 and the second end plate 13. The guide rod 38 passes through the cleaning plate 31 to prevent the cleaning plate 31 from deflecting and plays a guiding role. The threaded rod 32 passes through the first end plate 12 and extends to the outside where a handle 33 is fixedly installed.

[0021] During specific operation, when the heat exchanger body 1 is shut down for maintenance, the threaded rod 32 is rotated by turning the handle 33, thereby moving the cleaning plate 31 on the threaded rod 32. During the movement of the cleaning plate 31, the cleaning sleeve 36 can scrape off the dirt on the outer wall of the tube bundle 2, and the cleaning ring 37 can scrape off the dirt on the inner wall of the tube shell 11, causing the dirt to fall off.

[0022] It should also be noted that a drain outlet 34 is provided at the bottom of the tube shell 11, and the drain outlet 34 is covered with an arc-shaped drain cover 35. A support assembly 4 is installed between the second end plate 13 and the arc-shaped drain cover 35. The support assembly 4 includes a mounting tube 41 fixed on the second end plate 13, and also includes a connecting rod 42 with one end located in the mounting tube 41. The other end of the connecting rod 42 is fixedly connected to the arc-shaped drain cover 35, and a spring 43 is fixed between the connecting rod 42 and the mounting tube 41.

[0023] As the cleaning plate 31 continues to move, it will get closer and closer to the arc-shaped drain cover 35. As the two come into contact, the arc-shaped drain cover 35 will be pushed toward the second end plate 13, so that the arc-shaped drain cover 35 pushes the connecting rod 42 to squeeze the spring 43 to contract. At this time, 46 is opened, and the dirt pushed by the cleaning plate 31 can be discharged from the cleaning sleeve 36. When the cleaning plate 31 moves toward the first end plate 12, the spring 43 will gradually reset and push the arc-shaped drain cover 35 back to its original position, and then cover the cleaning sleeve 36. A seal is provided at the bottom of the drain cover 35 to prevent it from leaking when it is not moving.

[0024] In addition, the heat exchanger body 1 also includes a shell inlet 14 and a shell outlet 15 located on the tube shell 11, and also includes a tube side inlet and outlet 16. It should be noted that the working principle of the heat exchanger body in this solution is no different from that of the traditional shell and tube water solidification heat exchanger, so it will not be elaborated here.

[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
