The existing utility model patent with authorization publication number CN219714155U discloses a cleaning device for finned heat exchangers, which fixes the cleaning heat exchanger in a cleaning box through a clamping component and sprays and cleans it through a water spray component. The clamping component of the device requires manual operation to clamp and fix the heat exchanger, which is very inconvenient to use. In addition, the water spray component is fixedly installed above the heat exchanger and can only be sprayed and cleaned from top to bottom. The cleaning area of ​​the heat exchanger is limited, and the cleaning effect is very unsatisfactory. Utility Model Content

[0003] In order to address the deficiencies of the prior art, the utility model aims to provide a heat exchanger cleaning device, which can quickly clamp and fix the heat exchanger and continuously rotate the heat exchanger during spray cleaning, thereby performing all-round flushing and cleaning of the heat exchanger, with higher cleaning efficiency and better results.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A heat exchanger cleaning device comprises a box body and multiple spray heads, and a placement port is provided on the side wall of the box body; a support frame is fixedly provided horizontally in the middle of the box body, and a lower turntable is installed horizontally and rotatably above the support frame, and the lower turntable is connected to the motor power on the support frame; a lifting frame is provided for vertical movement above the inside of the box body, and a lifting drive mechanism for driving the lifting frame up and down is provided on the top of the box body; an upper turntable is provided below the lifting frame and opposite to the lower turntable, and the upper turntable is horizontally rotatably installed at the bottom of the lifting frame; clamping assemblies are installed on the opposite surfaces of the upper turntable and the lower turntable; the spray head is installed on the inner wall of the box body and the nozzle is arranged toward the middle of the box body; a filter plate is horizontally installed below the support frame, and a water storage chamber is provided at the bottom of the box body, and a water pump is provided in the water storage chamber, and the water outlet of the water pump is connected to the spray head.

[0012] Preferably, a sealed door is provided at the placement opening.

[0013] The beneficial effects of the utility model are:

[0014] 1. This utility model uses a motor to drive the lower turntable to rotate, thereby driving the heat exchangers installed on the two turntables to rotate synchronously. Combined with the spray head to spray water for flushing, the heat exchanger can be cleaned in all directions.

[0015] 2. When the first telescopic cylinder extends, the moving rod moves toward the two clamping plates. The second connecting rod swings, pushing the corresponding sliding sleeve. The two sleeves move toward each other on the moving rod, which in turn swings the first connecting rod and pushes the two clamping plates together, thus firmly clamping the two ends of the heat exchanger. Furthermore, gaskets are fixed on the opposing inner walls of the two clamping plates. These gaskets significantly increase friction with the heat exchanger, enhancing the secure fixation and preventing rigid contact between the clamping plates and the heat exchanger, preventing damage.

[0016] 3. The spray heads are arranged in multiple layers at equal intervals along the vertical direction on the inner wall of the box. The spray heads on each layer are also arranged at equal intervals, so that the spray heads can evenly spray cleaning water to the rotating heat exchanger in the middle, thereby significantly improving the cleaning efficiency.

[0017] 4. A filter plate is installed horizontally under the support frame. The filter plate can effectively filter the sewage flowing down from the cleaning. The filtered clean water flows into the water storage chamber for recycling, effectively utilizing water resources and being more environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a structural diagram of the utility model;

[0019] Figure 2 It is a top view of the clamping assembly of the present invention. DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0021] like Figure 1 As shown, the present invention proposes a heat exchanger cleaning device comprising a housing and multiple spray heads 7. The housing sidewalls are provided with a receiving opening, each equipped with a sealed door. A support frame 12 is fixedly mounted horizontally in the center of the housing. A lower turntable 6 is mounted horizontally and rotatably above the support frame 12. The lower turntable 6 is concentrically connected to the output shaft of a motor 61. The motor 61 drives the lower turntable 6 to rotate, thereby driving the heat exchanger 5 mounted on the two turntables to rotate synchronously. This, combined with the water spraying from the spray heads 7, allows for comprehensive cleaning of the heat exchanger 5.

[0022] A vertically movable lift frame 2 is installed above the interior of the box. Guide rails 11 are mounted vertically on the inner wall of the box, and the lift frame 2 slides vertically on these rails, significantly improving the stability of the lift frame 2 during movement. A lift drive mechanism is installed at the top of the box to drive the lift frame 2 up and down. This drive mechanism includes a second telescopic cylinder 21 (which can be a hydraulic cylinder). The second telescopic cylinder 21 is vertically mounted above the box, and its piston rod is fixedly connected to the lift frame 2. The extension and contraction of the second telescopic cylinder 21 drives the lift frame 2 to a stable vertical lift.

[0023] like Figure 2As shown, an upper turntable 3 is mounted below the lifting frame 2, opposite the lower turntable 6. The upper turntable 3 is mounted horizontally and rotatably on the bottom of the lifting frame 2. A clamping assembly 4 is mounted on opposing surfaces of the upper turntable 3 and the lower turntable 6. The clamping assembly 4 comprises a mounting frame 42, a first telescopic cylinder 43 (which can be a hydraulic cylinder), a travel rod 44, a connecting rod assembly, and two clamping plates 41. The mounting frame 42 is fixedly attached to the corresponding turntable. The two clamping plates 41 are arranged parallel to each other and slide horizontally within a chute provided on the turntable. The chute is perpendicular to the clamping plates 41. The sliding cooperation between the clamping plates 41 and the chute restricts the horizontal movement of the clamping plates 41 to either direction, effectively improving the stability of the movement of the clamping plates 41. The first telescopic cylinder 43 is installed on the mounting frame 42. The first telescopic cylinder 43 is vertically fixed to the middle part of the moving rod 44. Sliding sleeves 45 are provided at both ends of the moving rod 44. The connecting rod assembly includes a first connecting rod 47 and a second connecting rod 46 arranged in an eight shape. One end of the first connecting rod 47 and the second connecting rod 46 are both rotatably connected to the sliding sleeve 45, the other end of the first connecting rod 47 is rotatably connected to the corresponding splint 41, and the other end of the second connecting rod 46 is rotatably connected to the mounting frame 42.

[0024] When the first telescopic cylinder 43 extends, the moving rod 44 moves toward the two clamping plates 41, and the second connecting rod 46 swings and pushes the corresponding sliding sleeve 45 to move. The two sliding sleeves 45 move toward each other on the moving rod 44, which in turn causes the first connecting rod 47 to swing and push the two clamping plates 41 toward each other, thereby firmly clamping and fixing the two ends of the heat exchanger 5. In addition, gaskets are fixed on the opposing inner walls of the two clamping plates 41. These gaskets can significantly increase the friction between the clamping plates 41 and the heat exchanger 5, improving the fixing strength. They also prevent the clamping plates 41 from rigidly contacting the heat exchanger 5, preventing damage to the heat exchanger 5.

[0025] A water storage chamber 14 is provided at the bottom of the box, housing a water pump 15. The water outlet of the water pump 15 is connected to the spray head 7. The spray head 7 is mounted on the inner wall of the box, with its nozzle facing the center of the box. Multiple layers of spray heads 7 are evenly spaced vertically along the inner wall of the box, and the spray heads 7 on each layer are also evenly spaced. This allows the spray heads 7 to evenly spray cleaning water toward the rotating heat exchanger 5 in the center, significantly improving cleaning efficiency.

[0026] A filter plate 13 is horizontally installed below the support frame 12. The filter plate 13 can effectively filter the sewage flowing down from the cleaning. The filtered clean water flows into the water storage chamber 14 for recycling, which effectively utilizes water resources and is more environmentally friendly.

[0027] When using the utility model, the heat exchanger 5 is placed on the lower turntable 6 through the placement opening, and the second telescopic cylinder 21 is actuated to make the lifting frame 2 drive the upper turntable 3 to abut against the top of the heat exchanger 5. The first telescopic cylinders 43 of the two clamping assemblies 4 are started to drive the corresponding clamping plates 41 to clamp and fix the upper and lower ends of the heat exchanger 5. Then, the airtight door is closed, the motor 61 and the water pump 15 are started, and the spray head 7 can perform all-round flushing on the rotating heat exchanger 5 from all sides, which has higher cleaning efficiency and better effect.

The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application.
