Description

Technical Field

[0001] This utility model relates to the field of heat exchanger flushing technology, and in particular to a rotary GGH heat exchanger flushing device. Background Technology

[0002] The flushing device of GGH heat exchanger is mainly used to remove dust, scale or corrosion products accumulated on the surface of heat exchange elements in order to maintain the operating efficiency and safety of the heat exchanger. Its core functions include preventing particulate matter in flue gas from blocking the airflow channel, ensuring flue gas flow, removing dirt to improve heat exchange efficiency, reducing energy consumption, reducing the risk of corrosion caused by acid deposits, extending equipment life, and avoiding system resistance increase or shutdown accidents through regular maintenance, thus ensuring stable operation.

[0003] For example, the existing technology disclosed in Chinese Patent Publication No. "CN218673337U" is a rotary GGH heat exchanger flushing device, belonging to the technical field of flushing devices, which solves the technical problem of low cleaning efficiency of existing rotary GGH heat exchanger cleaning methods. The flushing device includes a track, a support base, a drive mechanism, and a high-pressure water gun. The track is mounted above the heat exchanger; the support base is movably mounted on the track; the drive mechanism drives the support base to reciprocate along the track; the high-pressure water gun is fixedly mounted on the support base, and the water outlet direction of the high-pressure water gun is parallel to the axis of rotation of the heat exchanger.

[0004] However, most existing GGH heat exchanger flushing devices typically have their flushing nozzles fixed at a uniform height during operation, making it impossible to flexibly adjust the flushing position according to actual needs. This fixed design leads to uneven flushing results; the upper side, closer to the nozzle, experiences greater water flow impact and a more thorough cleaning, while the lower side, farther away, experiences significantly reduced impact force and a relatively poorer cleaning effect. This uneven flushing force not only reduces overall cleaning efficiency but may also affect the long-term stable operation of the heat exchanger. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a rotary GGH heat exchanger flushing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rotary GGH heat exchanger flushing device is designed, including a connecting assembly detachably connected to the upper side of the heat exchanger. The connecting assembly is provided with a moving component and a driving component for moving the moving component. A cleaning component and an adjusting component for adjusting the length of the cleaning component are provided on the upper side of the moving component.

[0008] Furthermore, the connecting assembly includes a U-shaped rod, with baffles rotatably connected to both ends of the U-shaped rod. The two ends of the U-shaped rod and the two baffles are fitted together to form a sliding track. The two ends of the U-shaped rod are fixed to the baffles by a fixing assembly.

[0009] Furthermore, the moving component includes a platform, and a plurality of wheels are rotatably connected to the outer side of the platform, the wheels being slidably connected to the slide rail.

[0010] Furthermore, the drive assembly includes a dual-axis motor fixedly connected to the platform, with connecting rods fixedly connected to both ends of the dual-axis motor, and the connecting rods being fixedly connected to two opposing wheels respectively.

[0011] Furthermore, the cleaning component includes a sleeve fixedly connected to the platform, a round tube slidably connected inside the sleeve, a sealing ring fixedly connected to one end of the round tube, the sealing ring slidably connected to the sleeve, and a nozzle fixedly connected to the lower side of the round tube.

[0012] Furthermore, the adjusting assembly includes a knob threadedly connected to the sleeve, one end of the sleeve is formed with a deformable portion, the deformable portion abuts against the round tube, and the knob abuts against the deformable portion.

[0013] Furthermore, the fixing assembly includes two fixing plates respectively fixedly connected to both ends of the U-shaped rod and two positioning plates respectively fixedly connected to the baffle. A positioning rod is passed through and slidably connected to the end face of the fixing plate. A spring is fixedly connected between the positioning rod and the fixing plate.

[0014] The present invention provides a rotary GGH heat exchanger flushing device, which has the following advantages: The present invention is stably connected to the heat exchanger body through a connecting component, and a movable cleaning component is set inside the connecting component. Then, the working height of the cleaning component is controlled by adjusting the component, so that the heat exchanger can be cleaned evenly on both the top and bottom sides during the cleaning process, thereby improving the cleaning efficiency and effectively extending the service life of the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A rotary GGH heat exchanger flushing device includes a connecting assembly 1 detachably connected to the upper side of the heat exchanger. The connecting assembly 1 is provided with a moving assembly 2 and a driving assembly 3 for driving the moving assembly 2 to move. The upper side of the moving assembly 2 is provided with a cleaning assembly 4 and an adjusting assembly 5 for adjusting the length of the cleaning assembly 4. The GGH heat exchanger is prior art and will not be described in detail here.

[0022] It should be noted that the connecting component 1 includes a U-shaped rod 11, with baffles 12 rotatably connected to both ends of the U-shaped rod 11. The two ends of the U-shaped rod 11 and the two baffles 12 cooperate to form a slide rail 13. The two ends of the U-shaped rod 11 and the baffles 12 are fixed together by a fixing component 6. The baffles 12 and the two ends of the U-shaped rod 11 are both L-shaped, and the two cooperate to form the slide rail 13.

[0023] In this embodiment, the moving component 2 includes a platform 21, and a plurality of wheels 22 are rotatably connected to the outer side of the platform 21. The wheels 22 are slidably connected to the slide rail 13. In this embodiment, preferably four wheels 22 are evenly distributed on both sides of the platform 21 and slide within the slide rail 13.

[0024] Furthermore, the drive assembly 3 includes a dual-axis motor 31 fixedly connected to the platform 21. Both ends of the dual-axis motor 31 are fixedly connected to connecting rods 32. The connecting rods 32 are respectively fixedly connected to two opposite wheels 22. The dual-axis motor 31 drives the connecting rods 32 to rotate, and the rotation of the connecting rods 32 drives the two opposite wheels 22 to rotate, thereby driving the platform 21 to move.

[0025] The cleaning component 4 includes a sleeve 41 fixedly connected to the platform 21. A round tube 42 is slidably connected inside the sleeve 41. A sealing ring 43 is fixedly connected to one end of the round tube 42. The sealing ring 43 is slidably connected to the sleeve 41. A nozzle 44 is fixedly connected to the lower side of the round tube 42. The other side of the sleeve 41 is connected to a water pump and a water tank through a water pipe to supply water to the interior. When the nozzle 44 is moved, the sealing ring 43 prevents water leakage when the position of the nozzle 44 changes.

[0026] Furthermore, the adjustment component 5 includes a knob 51 threadedly connected to the sleeve 41. One end of the sleeve 41 is formed with a deformable part 52, which abuts against the round tube 42. The knob 51 abuts against the deformable part 52. By rotating the knob 51, the deformable part 52 is separated from the round tube 42, thereby adjusting the height of the nozzle 44. After the change is completed, rotating the knob 51 again makes the deformable part 52 abut against the round tube 42, thereby repositioning the nozzle.

[0027] Based on the above embodiments, the fixing component 6 includes two fixing plates 61 respectively fixedly connected to both ends of the U-shaped rod 11 and two positioning plates 62 respectively fixedly connected to the baffle 12. A positioning rod 63 is passed through and slidably connected to the end face of the fixing plate 61. A spring 64 is fixedly connected between the positioning rod 63 and the fixing plate 61. The positioning plate 62 has a hole adapted to the positioning rod 63. By pulling open the positioning rod 63 and flipping the baffle 12, the moving component 2 can be taken out from the connecting component 1. In use, the wheel 22 is placed in the slide 13, then the baffle 12 is rotated back, and then the positioning rod 63 is pulled open. After the baffle 12 is in place, the positioning rod 63 is released, so that the positioning rod 63 is locked into the positioning plate 62 by the spring 64, thereby fixing the baffle 12 and the U-shaped rod 11.

[0028] Working method: During operation, the component is connected to the heat exchanger via the connecting component 1, then the moving component 2 is placed inside the connecting component 1 and fixed to the slide rail 13 via the fixing component 6. The height of the cleaning component 4 is adjusted by the adjusting component 5. Then, an external water pump and water tank are connected to supply water to it. Then, the driving component 3 is started to move the moving component 2. After the upper side is cleaned, the height of the cleaning component 4 can be adjusted by the adjusting component 5, and then the lower side is cleaned.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
