Inside the heat exchanger housing 1, a heat exchange coil 2 is fixedly installed. A water inlet pipe 3 is fixedly communicated with the right side surface of the heat exchanger housing 1, and a water outlet valve 4 is fixedly communicated with the right side surface of the heat exchanger housing 1. A cover plate 5 is placed above the heat exchanger housing 1. Two groups of screws 6 are threadedly connected to the upper surface of the cover plate 5. Two groups of sealed bearings 7 are fixedly embedded in the inner side wall of the heat exchanger housing 1. The inner rings of the two groups of sealed bearings 7 are jointly fixedly connected to a threaded rod 8. A forward and reverse motor 9 is provided on the left side surface of the heat exchanger housing 1. The output end of the forward and reverse motor 9 is connected to the left end of the threaded rod 8. A threaded block 10 is threadedly connected to the outer surface of the threaded rod 8. A scraping plate 11 is fixedly connected to the bottom surface of the threaded block 10. By using the forward and reverse motor 9, the threaded rod 8 can be driven to rotate forward or backward. In this way, the rotation of the threaded rod 8 can be used to drive the threaded block 10 to drive the scraping plate 11 to move left and right, so as to clean the dirt on the inner bottom wall of the heat exchanger housing 1.

[0023] A control panel 12 is fixedly installed on the front surface of the heat exchanger housing 1. A warning sign 13 is fixedly connected to the back surface of the heat exchanger housing 1. Two groups of support legs 14 are fixedly connected to the bottom surface of the heat exchanger housing 1.

Two groups of positioning holes 16 are opened on the upper surface of the positioning plate 15. An observation window 17 is opened on the front surface of the heat exchanger housing 1. A transparent glass 18 is fixedly installed on the inner wall of the observation window 17. By using the warning sign 13, a certain warning effect can be achieved on non-staff members. By using the positioning plate 15 and the positioning holes 16, it is convenient for the staff to fixedly install this device on the ground. By using the observation window 17, it is convenient for the staff to check the operation conditions inside the heat exchanger housing 1.

[0024] Two groups of support columns 19 are fixedly connected to the inner bottom wall of the heat exchanger housing 1. The top ends of the two groups of support columns 19 are both connected to the bottom surface of the heat exchange coil 2. A U-shaped reinforcement frame 20 is fixedly connected to the left side surface of the heat exchanger housing 1.

The bottom surface of the sliding block 22 is connected to the upper surface of the scraping plate 11. By using the support columns 19, the heat exchange coil 2 can be supported, so that the heat exchange coil 2 can work more firmly. By using the U-shaped reinforcement frame 20, the forward and reverse motor 9 can be reinforced, so that the forward and reverse motor 9 can work more stably. By using the cooperation of the limiting rod 21, the sliding block 22 and the connecting column 23, the threaded block 10 and the scraping plate 11 can be limited, so that the threaded block 10 can drive the scraping plate 11 to move left and right more smoothly.

[0025] The working principle of the present utility model is as follows: When the device is in use, the staff first fix the device to the ground by using the positioning plate 15 and the positioning hole 16, and connect the device to an external power source. At this time, the device can start normal use. During the long-term use of the device, a large amount of dirt will appear on the inner bottom wall of the heat exchanger housing 1. When it is necessary to clean this dirt, the staff first start the forward and reverse motor 9 by using the control panel 12, drive the threaded rod 8 to rotate by using the forward and reverse motor 9, and use the rotation of the threaded rod 8 to make the threaded block 10 drive the scraper 11 to move left and right, so that the scraper 11 scrapes the dirt on the inner bottom wall of the heat exchanger housing 1. After the dirt on the inner bottom wall of the heat exchanger housing 1 is scraped off, the staff can discharge the dirt inside the heat exchanger housing 1 to the outside of the heat exchanger housing 1 by using the water outlet valve 4. The above is the entire operation process of the device.
