The embodiments of the present invention will be described below according to its overall structure.

[0028] Please refer to Figures 1-7 , a graphite heat exchanger cleaning device, including a box body 1. A slot 2 is opened at the center of the top of the box body 1. Shaft rods 3 are installed at the centers of the front and rear ends inside the box body 1. Cross plates 4 are installed at the opposite ends of the shaft rods 3. A clamping mechanism 5 for clamping the heat exchanger is installed on the outer side of the cross plates 4. Cleaning mechanisms 6 are installed at both ends of the bottom of the box body 1. A blanking assembly 7 is arranged at one end inside the box body 1.

[0029] As Figures 1-7As shown, the clamping mechanism 5 includes a fixed seat 501 installed on the outer side of the cross plate 4. Opposite ends of the fixed seat 501 are provided with grooves 502. Inside the grooves 502, a first electric telescopic rod 503 is installed. Opposite ends of the first electric telescopic rod 503 are installed with a heat exchanger body 504. Opposite ends of the cross plate 4 are equiangularly provided with arc-shaped support plates 505. Through the slot 2, the heat exchanger body 504 is placed inside the box body 1. At this time, the heat exchanger body 504 is supported by the provided arc-shaped support plates 505, and then the first electric telescopic rod 503 is controlled to extend to clamp and fix the heat exchanger body 504. During the rotation of the cross plate 4, the heat exchanger body 504 is continuously placed inside the box body 1 for clamping and fixing.

[0030] As Figures 1-7 shown, the shaft rod 3 at the rear end penetrates through the rear side of the box body 1 and is connected to a first driving device 8. By setting the first driving device 8 as a servo motor and setting an intermittent rotation bearing, the cross plate 4 is rotated to transport the heat exchanger body 504 to the bottom for cleaning.

[0031] As Figures 1-7 shown, the cleaning mechanism 6 includes bearings installed at the bottom of both ends inside the box body 1. Inside the bearings, a threaded rod 601 is rotatably connected. The outer wall of the threaded rod 601 is threadedly connected to a threaded seat 602. Opposite ends of the threaded seat 602 are connected to a second electric telescopic rod 603. Opposite ends of the second electric telescopic rod 603 are connected to an arc-shaped seat 604. Inside the arc-shaped seat 604, a cleaning cotton 605 is provided. During the cleaning process, the second electric telescopic rod 603 is controlled to extend to splice the two arc-shaped seats 604. At this time, the threaded seat 602 is limited, and the cleaning cotton 605 is combined into a circular ring structure and sleeved on the outer wall of the heat exchanger body 504. Then, the threaded rod 601 can be controlled to rotate to drive the threaded seat 602 to move so that the cleaning cotton 605 slides on the outer wall of the heat exchanger body 504 for cleaning.

[0032] As Figures 1-7 shown, the rear end of the threaded rod 601 penetrates through the rear side of the box body 1 and is connected to a first gear 9. The outer wall of the first gear 9 is drivingly connected to a chain 10. At the center of the bottom of the rear side of the box body 1, a second gear 11 meshing with the chain 10 is installed. By controlling the rotation of the second gear 11, the chain 10 is driven to drive the two first gears 9 to rotate, so that the threaded rod 601 rotates. The rotation of the second gear 11 can be driven by a servo motor.

[0033] As Figures 1-7 shown, both the upper and lower ends of the opposite sides of the arc-shaped seat 604 are provided with a clamping block 12 and a clamping groove 13, and the clamping blocks 12 and the clamping grooves 13 provided on the two groups of arc-shaped seats 604 are mutually staggered. By the mutual staggering of the clamping blocks 12 and the clamping grooves 13 provided on the two groups of arc-shaped seats 604, the splicing does not affect each other.

[0034] As shown Figures 1-7 in the figure, an inner groove 14 is formed in the inner side of the arc-shaped seat 604, a partition plate 15 is installed at the center of the inner groove 14, springs 16 are evenly connected to the upper and lower ends of the partition plate 15, the other ends of the springs 16 are connected to a C-shaped arc plate 17, a first through hole 18 is evenly formed at one end of the C-shaped arc plate 17 facing the cleaning cotton 605, a second through hole 19 misaligned with the first through hole 18 is evenly formed at one end of the arc-shaped seat 604 facing the cleaning cotton 605, a connecting plate 20 is connected to one end of the C-shaped arc plate 17 facing the clamping groove 13. When cleaning, the two arc-shaped seats 604 are spliced. At this time, the clamping block 12 is clamped into the clamping groove 13, and the clamping block 12 will abut against one end of the connecting plate 20 to squeeze the C-shaped arc plate 17 to compress the spring 16 and slide. At this time, the first through hole 18 and the second through hole 19 will be communicated. At this time, the cleaning liquid injected into the inner side of the C-shaped arc plate 17 will automatically flow into the cleaning cotton 605, enhancing the cleaning effect of the cleaning cotton 605. Moreover, a hole is formed in the outer side of the arc-shaped seat 604 for injecting the cleaning liquid, and it can be sealed after injection. After the cleaning is completed, the two arc-shaped seats 604 are separated by shortening the second electric telescopic rod 603 provided. At this time, the elastic force of the spring 16 provided makes the C-shaped arc plate 17 reset so that the first through hole 18 and the second through hole 19 are misaligned.

[0035] As shown Figures 1-7 in the figure, the blanking assembly 7 includes an adjusting rod 701 installed at one end of the center inside the box body 1. Cross transfer plates 702 are evenly arranged on the outer wall of the adjusting rod 701. The rear end of the adjusting rod 701 penetrates through the rear side of the box body 1 and is connected to a second driving device 703. An opening 704 is formed at one end inside the box body 1, and a transport plate 705 is installed at one end inside the box body 1. When the heat exchanger body 504 at the bottom is cleaned, when the heat exchanger body 504 is transported to the right side, the heat exchanger body 504 is supported by the cross transfer plates 702 provided. Then, the heat exchanger body 504 is placed on the cross transfer plates 702 by controlling the first electric telescopic rod 503 to shorten. Then, the cross transfer plates 702 rotate to transfer the heat exchanger body 504 to the transport plate 705 and move it to the outside of the box body 1 for collection.

[0036] Working principle: When in use, the heat exchanger body 504 is placed into the box body 1 through the slot 2. At this time, the heat exchanger body 504 is supported by the arranged arc-shaped support plate 505, and then the first electric telescopic rod 503 is controlled to extend to clamp and fix the heat exchanger body 504. During the rotation of the cross plate 4, the heat exchanger body 504 is continuously placed into the box body 1 for clamping and fixing. The first driving device 8 is set to use a servo motor, and through the arranged intermittent rotation bearing, the cross plate 4 is rotated to transport the heat exchanger body 504 to the bottom for cleaning. During the cleaning process, the second electric telescopic rod 603 is set to extend to splice the two arc-shaped seats 604. At this time, the threaded seat 602 is limited, and the cleaning cotton 605 is combined into a circular ring structure and sleeved on the outer wall of the heat exchanger body 504. Then, by controlling the rotation of the threaded rod 601, the threaded seat 602 can be driven to move so that the cleaning cotton 605 slides on the outer wall of the heat exchanger body 504 for cleaning. When cleaning, the two arc-shaped seats 604 are spliced. At this time, the block 12 is clamped into the slot 13, and the block 12 will abut against one end of the connecting plate 20, thereby squeezing the C-shaped arc plate 17 and compressing the spring 16 to slide. At this time, the first through hole 18 will be communicated with the second through hole 19, and the cleaning liquid injected into the inner side of the C-shaped arc plate 17 will automatically flow into the cleaning cotton 605, enhancing the cleaning effect of the cleaning cotton 605. Moreover, holes are opened on the outer side of the arc-shaped seat 604 for injecting cleaning liquid, and it can be sealed after injection. After the cleaning is completed, the second electric telescopic rod 603 is set to shorten to separate the two arc-shaped seats 604. At this time, due to the elastic force of the spring 16, the C-shaped arc plate 17 is reset so that the first through hole 18 is misaligned with the second through hole 19. When the heat exchanger body 504 at the bottom is cleaned, when the heat exchanger body 504 is transported to the right side, the heat exchanger body 504 is supported by the arranged cross transfer plate 702, and then the first electric telescopic rod 503 is controlled to shorten to place the heat exchanger body 504 on the cross transfer plate 702. Then, the cross transfer plate 702 rotates to transfer the heat exchanger body 504 to the transport plate 705 and move it to the outside of the box body 1 for collection.
