[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a descaling volumetric heat exchanger, comprising:

[0038] Heat exchange tank 1, the side wall of the heat exchange tank 1 is fixedly connected to the heat exchange outer tube 2, the interior of the heat exchange outer tube 2 is fixedly connected to the annular heat exchange tube 6, the outer side of the annular heat exchange tube 6 is slidably connected to the scraper 8, and the bottom of the heat exchange tank 1 is provided with a quick-release assembly for quickly installing a filter device;

[0039] The descaling component is used to drive the scraper 8 to slide on the outside of the annular heat exchange tube 6 to achieve the purpose of removing dirt on the outside of the annular heat exchange tube 6. It is installed on the top of the heat exchange outer tube 2. The descaling component includes a motor 4, the output end of the motor 4 is fixedly connected to a turntable 5, and an indented slider 9 is provided below the turntable 5. The left end of the indented slider 9 is fixedly connected to a push rod 7, and the end of the push rod 7 away from the indented slider 9 is fixedly connected to the top of the scraper 8. The bottom end of the turntable 5 is fixedly connected to a slide rod away from the center position. The slide rod is slidably connected to the inside of the indented slider 9, and the bottom of the indented slider 9 is slidably connected to the outside of the heat exchange outer tube 2. The motor 4 is fixedly connected to the outside of the heat exchange tank 1 through a hoop. A water outlet is installed on the top of the heat exchange tank 1, and three bottom feet are installed at the bottom of the heat exchange tank 1. The end of the heat exchange outer tube 2 away from the heat exchange tank 1 is fixedly connected to the heat exchange tube. A water inlet is provided on the top of the heat exchange tube, and a water outlet is provided on the bottom of the heat exchange tube. The heat exchange tank 1 and the heat exchange tube are threadedly connected.

[0040] Specifically, in this embodiment, a water outlet is installed on the top of the heat exchange tank 1, and three bottom feet are installed on the bottom of the heat exchange tank 1. The side wall of the heat exchange tank 1 is fixedly connected to the heat exchange outer tube 2. An annular heat exchange tube 6 is fixedly connected to the inside of the heat exchange outer tube 2, and most of the annular heat exchange tube 6 is located inside the heat exchange tank 1. The motor 4 is fixed to the outside of the heat exchange tank 1 through a ring hoop. After starting the motor 4, the turntable 5 can be driven to rotate in a circular manner. Since the sliding rod at the bottom of the turntable 5 is away from the center of the turntable 5, and the sliding rod can only slide inside the sunken slider 9, the sliding rod will drive the sunken slider 9 to perform linear motion in the left and right directions on the outside of the heat exchange outer tube 2. Since the bottom of the sunken slider 9 is completely in contact with the heat exchange outer tube 2, it can play a role in limiting the sunken slider 9. When the sunken slider 9 slides to the left, it will push the push rod 7 to move, and the push rod 7 drives the scraper 8 to slide on the outside of the annular heat exchange tube 6, which can scrape off the solid dirt accumulated on the outside of the annular heat exchange tube 6, thereby ensuring high heat exchange efficiency.

[0041] Reference Figure 6 - Figure 8 The quick-release assembly includes an outlet pipe 11, the outer top of the outlet pipe 11 is fixedly connected to the bottom of the heat exchange tank 1, and an annular groove is opened on the outer side of the outlet pipe 11, and the outer side of the annular groove is fixedly connected to the outer cylinder 10, and the outer side of the outer cylinder 10 is rotatably connected to the rotating drum 3. The four sides of the annular groove are slidably connected to the limit plates 15, and the opposite sides of the four limit plates 15 are fixedly connected to the clamping blocks 16. The opposite sides of the four limit plates 15 are fixedly connected to the pull rope 13. The outer side of the pull rope 13 is sleeved with a spring 14, and a screen 12 is installed between the four clamping blocks 16. One end of the spring 14 is fixedly connected to the inside of the annular groove, and the other end of the spring 14 is fixedly connected to the inner wall of the outer cylinder 10. The outer cylinder 10 has four holes at the position corresponding to the pull rope 13. The outer side of the pull rope 13 is slidably connected to the inside of the hole, and the end of the pull rope 13 away from the limit plate 15 is fixedly connected to the inner wall of the rotating drum 3.

[0042] Specifically, a water outlet pipe 11 is fixed at the bottom of the heat exchange tank 1, and the water after heat exchange can be discharged from the water outlet pipe 11. An annular groove is opened on the outside of the water outlet pipe 11, and an outer cylinder 10 is fixed on the outside of the annular groove. The weaker part of the outer cylinder 10 forms a closed cavity with the annular groove. Four limiting plates 15 slide around the cavity. A clamping block 16 is fixed between the four limiting plates 15. The clamping block 16 is used to clamp the screen 12 inside the water outlet pipe 11. The water outlet pipe 11 can filter out hard particles contained in the water. Dirt, but after a period of time, the screen 12 needs to be removed and replaced, just rotate the drum 3 located outside the outer drum 10, and then pull the four pull ropes 13. The pull ropes 13 pull the limit plates 15 to slide in the cavity, and compress the four springs 14 inside the cavity. At this time, the clamping blocks 16 are separated, and the screen 12 can be replaced. After the replacement is completed, the drum 3 can be rotated. Under the action of the springs 14, the clamping blocks 16 will clamp the screen 12 in place again, ensuring that the filtration efficiency is not affected and preventing dirt from affecting the water after heat exchange.

[0043] Working principle: In order to remove a large amount of dirt generated on the outside of the annular heat exchange tube 6 due to heat exchange, a scraper 8 is slidably connected to the outside of the annular heat exchange tube 6. The motor 4 fixed on the outside of the heat exchange tank 1 can drive the turntable 5 to rotate. The slide rod at the bottom of the turntable 5 can drive the sunken slider 9 to slide linearly on the outside of the heat exchange outer tube 2, and drive the scraper 8 to slide left and right on the outside of the annular heat exchange tube 6 through the top rod 7, which can effectively scrape off the dirt accumulated on the outside of the annular heat exchange tube 6, ensuring that the heat exchange efficiency is not affected. The bottom of the heat exchange tank 1 The fixed water outlet pipe 11 can discharge the water after heat exchange. In order to ensure that dirt is not discharged with it, it needs to be filtered. A screen 12 is provided inside the water outlet pipe 11. When the screen 12 needs to be replaced, it is only necessary to rotate the drum 3 and drive the four clamping blocks 16 apart through the pull rope 13. At this time, a new screen 12 can be replaced. After loosening the drum 3, the clamping blocks 16 will re-clamp the screen 12 under the action of the compressed spring 14, which greatly reduces the time required to replace the screen 12 and ensures the efficiency of the equipment operation.
