[0002] A rotary heat exchanger, namely a rotary total heat exchanger, mainly consists of a wheel core, a seal, a shell, a power mechanism, etc. It can use a honeycomb wheel core as a heat transfer medium to absorb energy from high-temperature gas and release it in low-temperature gas, realizing energy conversion between gas and gas. Since the wheel core on the rotating wheel is the main heat exchange component, to ensure its working ability, it is necessary to keep the surface of the wheel core clean. Therefore, it is necessary to disassemble and clean the wheel core regularly.

[0003] For example, the patent technical document with the publication number CN219869268U discloses a quick-disassembly structure of a rotary heat exchanger, including a wheel frame and a wheel core installed on the wheel frame. The wheel frame includes a wheel frame body. A shaft sleeve is provided at the central position of the wheel frame body. A cross-shaped distributed wheel spoke is fixed between the wheel frame body and the shaft sleeve. An installation groove for placing the wheel core is formed between adjacent wheel spokes. A disassembly and assembly component is rotatably arranged in the shaft sleeve, and a locking component for cooperating with the disassembly and assembly component to quickly disassemble the wheel core by rotation is arranged on the shaft sleeve.

[0004] In the above technical solution, the disassembly and assembly component can be used to quickly disassemble a single sector-shaped wheel core, and the block-by-block disassembly method can facilitate the overall cleaning of the wheel core. However, although the wheel core is divided into multiple blocks, during cleaning, each wheel core is mainly cleaned one by one with a high-pressure water gun. Therefore, the cleaning efficiency still needs to be further improved. Summary of the Invention

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, and does 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 construed as a limitation to the present invention. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0018] As Figures 1 to 3 shown, the present utility model discloses a cleaning device for a rotary heat exchanger, which includes a machine table 1. A frame 2 is provided on the machine table 1. A hydraulic cylinder 3 is provided on the frame 2. An installation seat 4 is provided at the output end of the hydraulic cylinder 3. A connecting frame 5 is provided on the installation seat 4. There are multiple connecting frames 5 and they are evenly distributed in a circumferential manner. The connecting frame 5 can move in the radial direction. A brush roller 6 is rotatably connected inside the connecting frame 5. A rotating motor 7 is provided on one side of the connecting frame 5. The rotating motor 7 is used to drive the brush roller 6 to rotate. A placing seat 8 is provided below the brush roller 6. A sector-shaped placing groove 81 adapted to the sector-shaped wheel core is provided on the placing seat 8. There are multiple sector-shaped placing grooves 81 and they are evenly distributed in a circumferential manner. A drive mechanism is provided on the installation seat 4. When it is necessary to clean multiple sector-shaped wheel cores, the worker first sprays the cleaning liquid on the placing seat 8, and then respectively places the multiple sector-shaped wheel cores into the respective sector-shaped placing grooves 81. Subsequently, the hydraulic cylinder 3 drives the installation seat 4 to move downward, so that the brush roller 6 on the connecting frame 5 can contact the surface of the sector-shaped wheel core. Subsequently, the drive mechanism drives each connecting frame 5 to move synchronously, so that the brush roller 6 covers the sector-shaped wheel cores in the entire sector-shaped placing groove 81. At this time, the brush roller 6 driven by the rotating motor 7 to rotate can complete the cleaning of the surfaces of multiple sector-shaped wheel cores simultaneously. Thus, by cleaning multiple sector-shaped wheel cores simultaneously, the overall cleaning efficiency of the wheel cores can be improved, and the continuous rotation of the brush roller 6 can ensure the cleaning effect on the surface of the sector-shaped wheel core. After the surface of the sector-shaped wheel core is cleaned, the hydraulic cylinder 3 drives the installation seat 4 to move upward, so that the brush roller 6 can be separated from the sector-shaped wheel core, thereby facilitating the removal of the sector-shaped wheel core from the sector-shaped placing groove 81.

[0019] In this embodiment, the specific structure of the driving mechanism includes a driving bevel gear 91 and a driven bevel gear 92. The mounting base 4 is provided with a connecting flange 41 in the radial direction. The connecting flange 41 is rotatably connected with a lead screw 93. The driving bevel gear 91 is rotatably connected to the center of the mounting base 4. The driven bevel gear 92 is located at one end of the lead screw 93 and meshes with the driving bevel gear 91. A driving motor 94 is provided on the mounting base 4. The driving motor 94 is connected to the driving bevel gear 91 and is used to drive the driving bevel gear 91 to rotate. A connecting seat 95 that can form a threaded fit with the lead screw 93 is sleeved on the outer periphery of the lead screw 93. The connecting frame 5 is fixed to the connecting seat 95. The principle that the driving mechanism drives each connecting frame 5 to move synchronously in the radial direction is that after the driving motor 94 drives the driving bevel gear 91 to rotate, the driven bevel gear 92 meshing with the driving bevel gear 91 can drive the lead screw 93 to rotate. As the lead screw 93 rotates, the connecting seat 95 sleeved on the outer periphery of the lead screw 93 and forming a threaded fit can move along the direction of the lead screw 93. In this way, the connecting frame 5 connected to the connecting seat 95 can be driven to move in the radial direction. Therefore, by driving the driving bevel gear 91 to rotate reciprocally in different directions by the driving motor 94, the brush roller 6 can be driven to move reciprocally in the radial direction, so as to ensure the cleaning effect on the surface of the sector wheel core.

[0020] In this embodiment, in order to ensure the stability of the movement of the connecting seat 95 along the direction of the lead screw 93, guide rods 10 are further provided on both sides of the lead screw 93. The ends of the guide rods 10 are fixed to the connecting flange 41. The connecting seat 95 is provided with guide holes corresponding to the guide rods 10. The connecting seat 95 is sleeved on the guide rods 10 through the guide holes and can form a sliding fit between the two. When the connecting seat 95 moves along the direction of the lead screw 93 as the lead screw 93 rotates, a sliding fit can be formed between the guide holes and the guide rods 10, so as to play a role in guiding and limiting the movement path of the connecting seat 95 and ensure the stability of the movement of the connecting seat 95 along the direction of the lead screw 93.

[0021] In this embodiment, slide rails 11 are further provided on both sides of the frame 2. The mounting base 4 is provided with an extending end 42 extending towards the slide rails 11. The end of the extending end 42 is provided with a slider 12. The slider 12 is coupled to the slide rails 11 and can form a sliding fit between the two. When the hydraulic cylinder 3 drives the mounting base 4 to move up and down, a sliding fit can be formed between the slide rails 11 and the slider 12, so as to play a guiding role in the movement of the mounting base 4 and ensure the stability of the movement of the mounting base 4. And when the slider 12 is coupled to the slide rails 11, it can also support the mounting base 4 to a certain extent and reduce the load borne by the output end of the hydraulic cylinder 3.

[0022] In this embodiment, an installation groove is provided on the machine table 1, and a cam divider 13 is arranged in the installation groove. The output end of the cam divider 13 is connected to the placement seat 8. The cam divider 13 is used to drive the placement seat 8 to rotate. By arranging the cam divider 13, the placement seat 8 can be driven to rotate intermittently, so that each sector placement groove 81 on the placement seat 8 can face the brush roller 6, thereby further increasing the number of sector wheel cores that can be cleaned simultaneously and further improving the overall cleaning efficiency of the wheel cores.

[0023] This specific embodiment is only an interpretation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively according to needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
