[0033] The sealing assembly includes a rubber sealing ring 20 slidably disposed in the heat inlet pipe 4 and a pushing mechanism disposed in the heat inlet pipe 4. The rubber sealing ring 20 is used to seal the gap between the heat inlet pipe 4 and the external pipe body 29. The pushing mechanism is used to move the rubber sealing ring 20 to the connection position after the heat inlet pipe 4 and the external pipe body 29 are connected.

[0034] The scraping assembly includes an annular scraper 11 arranged in the shell body 1 and a driving mechanism arranged in the shell body 1. The annular scraper 11 is used to scrape scale on the inner wall of the shell body 1, and the driving mechanism is used to drive the annular scraper 11 to move along the axial direction of the shell body 1.

[0035] The main function of the rubber sealing ring 20 is to seal the gap at the connection between the heat inlet pipe 4 and the external pipe body 29 after the heat inlet pipe 4 is connected to the external pipe body 29, so as to improve the sealing performance; the main function of the pushing mechanism is to place the rubber sealing ring 20 in the heat inlet pipe 4 before the external pipe body 29 is connected, and to push the rubber sealing ring 20 to move to the connection between the heat inlet pipe 4 and the external pipe body 29 after the external pipe body 29 is connected to the heat inlet pipe 4; the main function of the annular scraper 11 is to scrape off the scale attached to the inner wall of the outer shell body 1 by moving along its axial direction in the outer shell body 1; the main function of the driving mechanism is to drive the annular scraper 11 to move in the outer shell body 1. On the whole, the present invention improves the sealing effect of the equipment at the heat inlet pipe by arranging a movable rubber sealing ring in the heat inlet pipe, reduces the waste of resources when the equipment is in use, improves the effect of waste heat recovery of the equipment, prevents equipment damage caused by pressure fluctuations, increases the service life of the equipment, and greatly improves the use effect of the equipment. At the same time, by arranging an annular scraper that can move along the inner wall of the outer shell body, the function of the equipment to automatically scrape off the scale on the inner wall of the equipment is guaranteed, avoiding the problem that the traditional equipment is very inconvenient for the staff to clean it due to the long pipe wall, reducing the difficulty of the staff to clean the inner wall of the equipment, improving the comfort of the equipment cleaning, and improving the use effect of the equipment.

[0036] To further optimize the solution, a controller is also provided, and the controller is electrically connected to the pushing mechanism and the driving mechanism.

[0037] A further optimized solution is that the pushing mechanism includes an annular sealing device plate 17, which is slidably connected to the heat inlet pipe 4, and a rubber sealing ring 20 is arranged on the outer wall of the annular sealing device plate 17, and a plurality of pushing members are arranged between the annular sealing device plate 17 and the heat inlet pipe 4.

[0038] like Figure 3 and Figure 6 As shown, a through hole is provided in the middle of the annular sealing device plate 17 to facilitate the flow of fluid, so as to reduce the influence of the annular sealing device plate 17 on the flow of fluid.

[0039] A further optimized solution is that the pushing member includes a sealing movable groove 13 opened on the inner wall of the heat inlet pipe 4, the sealing movable groove 13 is arranged parallel to the axis of the heat inlet pipe 4, a threaded connecting plate 16 is slidably connected in the sealing movable groove 13, an annular sealing device plate 17 is fixedly connected to the threaded connecting plate 16, a second threaded rod 15 is rotatably connected in the heat inlet pipe 4, the second threaded rod 15 is transmission-connected to the threaded connecting plate 16, a second drive motor 14 is fixedly connected in the heat inlet pipe 4, and the output shaft of the second drive motor 14 is coaxially fixedly connected to one end of the second threaded rod 15.

[0040] like Figure 3 and Figure 6 As shown, after the heat inlet pipe 4 is connected to the external pipe body 29, the controller controls the second drive motor 14 to rotate, and the second drive motor 14 drives the second threaded rod 15 to rotate. When the second threaded rod 15 rotates, the threaded connecting plate 16 is driven by thread transmission to move in the sealing movable groove 13 toward the square of the external pipe body 29, and the annular sealing device plate 17 is pushed outward by the threaded connecting plate 16, thereby driving the rubber sealing ring 20 to move out of the heat inlet pipe 4 and move to the connection between the heat inlet pipe 4 and the external pipe body 29, thereby sealing the gap at the connection and improving the sealing performance.

[0041] After the outer tube body 29 is disconnected from the heat inlet pipe 4 , in order to prevent the rubber sealing ring 20 from being hit or damaged in the external environment, the second drive motor 14 can be controlled by the controller to rotate in the opposite direction to move the rubber sealing ring 20 back into the heat inlet pipe 4 .

[0042] According to a further optimized solution, a second slide groove 23 is provided at the bottom of the sealing movable groove 13 , a second slider 24 is slidably connected in the second slide groove 23 , and the second slider 24 is fixedly connected to the threaded connecting plate 16 .

[0043] like Figure 3 As shown, by providing the second slider 24, the threaded connecting plate 16 can be limited to prevent the threaded connecting plate 16 from getting stuck, thereby ensuring the stability of the threaded connecting plate 16 when in use.

[0044] According to a further optimized solution, a plurality of second motor cavities 12 are provided in the heat inlet pipe 4 , and the second drive motor 14 is fixedly connected in the second motor cavities 12 .

[0045] According to a further optimized solution, the heat outlet pipe 5 is connected to the external pipe body 29 via a first connecting flange 27 , and the heat inlet pipe 4 is connected to the external pipe body 29 via a second connecting flange 28 .

[0046] According to a further optimized solution, an annular groove 18 is provided on the outer wall of the annular sealing device plate 17 along the circumferential direction, a rubber sealing ring 20 is arranged in the annular groove 18 , and a plurality of springs 19 are abutted between the annular groove 18 and the rubber sealing ring 20 .

[0047] According to a further optimization scheme, annular grooves 25 are respectively provided on two opposite side walls of the annular groove 18 , arc-shaped sliders 26 are respectively fixedly connected to two opposite side walls of the rubber sealing ring 20 , and two groups of arc-shaped sliders 26 are respectively slidably connected in two groups of annular grooves 25 .

[0048] like Figure 3 and Figure 7 As shown, the annular groove 25 and the arc-shaped slider 26 are used in combination to limit the rubber sealing ring 20, preventing the rubber sealing ring 20 from relatively shifting when following the movement of the annular sealing device plate 17, thereby ensuring the stability of the equipment during use.

[0049] Under the elastic action of the spring 19, the rubber sealing ring 20 compensates for the gap between the first connecting flange 27 and the second connecting flange 28 on the left side, thereby improving the sealing effect at the heat inlet pipe 4 of the equipment and reducing resource waste when the equipment is used.

[0050] A further optimized solution is that the driving mechanism includes a scraping movable groove 7 opened at the bottom of the outer shell body 1, the scraping movable groove 7 is arranged along the axial direction of the outer shell body 1, a threaded connecting block 10 is slidably connected in the scraping movable groove 7, an annular scraper 11 is fixedly connected to the threaded connecting block 10, and a sliding driving member is arranged between the threaded connecting block 10 and the outer shell body 1.

[0051] A further optimized solution is that the sliding drive member includes a first threaded rod 9 rotatably connected in the scraping movable groove 7, the first threaded rod 9 is transmission-connected to a threaded connection block 10, a first drive motor 8 is fixedly connected in the outer shell body 1, and the output shaft of the first drive motor 8 is coaxially fixedly connected to one end of the first threaded rod 9.

[0052] like Figure 4 and Figure 5As shown, when it is necessary to clean the scale in the housing body 1, the controller controls the first drive motor 8 to rotate, and the first drive motor 8 rotates to drive the first threaded rod 9 to rotate. When the first threaded rod 9 rotates, the first slider 22 is driven to move from one end of the housing body 1 to the other end in the first slide groove 21 through thread transmission, and the annular scraper 11 is driven to move synchronously, and the scale on the inner wall of the housing body 1 is scraped off by the movement of the annular scraper 11. The controller controls the first drive motor 8 to reverse, and the annular scraper 11 can be controlled to move in the opposite direction.

[0053] According to a further optimized solution, a first sliding groove 21 is provided at the bottom of the scraping movable groove 7 , a first sliding block 22 is slidably connected in the first sliding groove 21 , and the first sliding block 22 is fixedly connected to the threaded connection block 10 .

[0054] like Figure 5 As shown, the first slide groove 21 and the first slider 22 are used in combination to limit the threaded connection block 10, prevent the threaded connection block 10 from rotating, and ensure the stability of the threaded connection block 10 when in use.

[0055] To further optimize the solution, a heat transfer component is arranged in the shell body 1, and a tube sheet 32 ​​is detachably connected between one end of the heat transfer component and the shell body 1, and the two ends of the shell body 1 are respectively fixedly connected with a head 3, and the heat inlet pipe 4 and the heat outlet pipe 5 are connected to the two ends of the heat transfer component through the two heads 3 respectively.

[0056] According to a further optimization scheme, a cold outlet pipe 30 and a cold inlet pipe 31 are connected to the side wall of the shell body 1, the cold outlet pipe 30 and the cold inlet pipe 31 are connected to the inside of the shell body 1, and the cold outlet pipe 30 and the cold inlet pipe 31 are arranged corresponding to the heat transfer component.

[0057] like Figure 2 As shown, the main function of the tube sheet 32 ​​is to prevent the fluid from entering the shell body 1 and directly contacting the cold fluid flowing between the cold outlet pipe 30 and the cold inlet pipe 31 after the fluid enters the head 3 through the hot inlet pipe 4, but enters the heat transfer component through the tube sheet 32, then flows into the other head 3 from the other end of the heat transfer component, and finally flows out from the hot outlet pipe 5. The hot fluid entering from the hot inlet pipe 4 enters the heat transfer component and exchanges heat with the cold fluid outside the heat transfer component to achieve a heat exchange effect. The heat transfer component is a common structure, so its working principle and working process will not be repeated.

[0058] The tube sheet 32 ​​is detachable. In daily use, the tube sheet 32 ​​is clamped between the heat transfer component and the inner wall of the shell body 1 to ensure that the hot fluid can directly enter the heat transfer component after flowing from the heat inlet pipe 4. When cleaning is needed, the head 3 is removed and the tube sheet 32 ​​can be taken out of the shell body 1 to avoid affecting the movement of the annular scraper 11.

[0059] According to a further optimized solution, a support leg 33 is fixedly connected to the bottom of the housing body 1 .

[0060] The working process of this embodiment is as follows: before connection, the rubber sealing ring 20 is in the heat inlet pipe 4. The corresponding external pipe body 29 is connected to the heat inlet pipe 4 and the heat outlet pipe 5 respectively, and then the second driving motor 14 is controlled by the controller to rotate, so that the threaded connecting plate 16 drives the annular sealing device plate 17 to move toward the direction of the external pipe body 29, and finally the annular sealing device plate 17 drives the rubber sealing ring 20 to move to the connection between the heat inlet pipe 4 and the external pipe body 29, so as to compensate for the gap at the connection and improve the sealing performance.

[0061] After using it for a period of time, the staff can remove the head 3 near the end of the tube sheet 32 ​​by removing the connecting plate 2, and then take out the tube sheet 32, and then control the first drive motor 8 to rotate through the controller, so that the threaded connecting block 10 drives the annular scraper 11 to move along the axis of the shell body 1 on the inner wall of the shell body 1, so that the annular scraper 11 scrapes off the scale on the inner wall of the shell body 1 during the movement, so that it falls off, which is convenient for the staff to clean.

[0062] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, 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.

[0063] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
