[0012] (1) This device uses a turbulent ring made of titanium-nickel alloy and a turbulent plate structure with a gradually changing length.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 As shown, this utility model is an alloy physical descaling and scale inhibition device, including a turbulent ring 1, a pipe 2, a connecting ring 3, a fixing buckle 4, and a descaling component. The turbulent ring 1 is made of titanium-nickel alloy. The connecting ring 3 is fixedly connected to the fixing buckle 4 on the outside. The pipe 2 is detachably connected to the connecting ring 3 through the fixing buckle 4. The turbulent ring 1 is rotatably connected to the connecting ring 3 on the inside. The descaling component is fixedly connected to the turbulent ring 1. The turbulent ring 1 is provided with multiple turbulent plates 5. The roots of the turbulent plates 5 are evenly distributed along the inner circumference of the turbulent ring 1. Their ends extend axially in the direction of water flow in the pipe 2 and radially in the direction of the axis of the turbulent ring 1. The length of the multiple turbulent plates 5 is uniformly longer or shorter along the inner circumference of the turbulent ring 1.

[0023] The above-mentioned device first establishes the core load-bearing structure of the device. The connecting ring 3 is integrally cast from stainless steel. The external fixed connection of the connecting ring 3 is the fixing buckle 4. The pipe 2 is detachably connected to the connecting ring 3 through the fixing buckle 4, which facilitates the disassembly and maintenance of the device in the later stage. The turbulence ring 1 is rotatably connected to the inside of the connecting ring 3 through an embedded sealed bearing. The bearing is a waterproof and wear-resistant miniature bearing, which can effectively prevent impurities in the pipe from entering the bearing and ensure that the turbulence ring 1 can rotate flexibly under the impact of water flow, while avoiding fluid leakage.

[0024] The turbulence ring 1 is made of titanium-nickel shape memory alloy. Utilizing the excellent corrosion resistance and wear resistance of titanium-nickel alloy, it can undergo slight deformation within a range of fluid temperature changes, further enhancing the water flow disturbance effect and ensuring long-term stable operation of the device in complex fluid environments such as high temperatures. Multiple turbulence plates 5 are integrally formed on the inner ring surface of the turbulence ring 1. The roots of the turbulence plates 5 are evenly distributed along the circumference of the inner ring of the turbulence ring 1, and the included angle between adjacent turbulence plates 5 is uniformly set to ensure that the water flow is completely cut. The ends of the turbulence plates 5 extend axially towards the water flow direction in the pipe 2, forming an appropriate included angle with the axis of the turbulence ring 1, which can efficiently guide the water flow to form axial turbulence; extending radially towards the axis of the turbulence ring 1, it can both ensure the turbulence effect and avoid excessively increasing water flow resistance. The lengths of the multiple turbulence plates 5 uniformly increase or decrease along the circumference of the inner ring of the turbulence ring 1, forming a gradual structure, which can create a spiral turbulence field in the pipe, disrupting the growth conditions for scale crystallization and further inhibiting scale formation.

[0025] The turbulence plate 5 is tilted in the same circumferential direction, which allows the water flow to provide circumferential rotational force to the turbulence plate 5. This design means that when the water flow impacts each tilted blade, it generates a circumferential component force in the same direction. These components, when superimposed, form a continuous rotational torque, driving the ring body to rotate. This, in turn, drives the turbulence ring 1 to rotate. The descaling component is fixedly connected to the turbulence ring 1 and rotates synchronously with it, achieving descaling of the inner wall of the pipe 2.

[0026] Optionally, the descaling assembly includes a first spring 6, one end of which is fixedly connected to the turbulence ring 1, and the other end is fixedly connected to a connecting plate 7. The connecting plate 7 is sleeved with the inner wall of the connecting ring 3. One end of a connecting rod 8 is hinged to the connecting plate 7, and the other end of the connecting rod 8 is fixedly connected to a scraper 9. The connecting rod 8 is also fixedly connected to one end of a second spring 10, and the other end of the second spring 10 is fixedly connected to the connecting plate 7.

[0027] Through the above-mentioned device, the descaling component adopts a double-spring elastic structure design to ensure that the scraper 9 impacts the inner wall of the pipe 2, thereby improving the descaling efficiency. The first spring 6 is a stainless steel compression spring, one end of which is fixedly connected to the turbulence ring 1 by welding, and the other end is fixedly connected to the connecting plate 7 by bolts. With the elastic support of the first spring 6, the connecting plate 7 will vibrate when impacted by water flow, and the scraper 9 will also vibrate up and down, thereby improving the descaling efficiency of the scraper 9. The connecting plate 7 is made of annular stainless steel plate, and its inner diameter is fitted with the inner wall of the connecting ring 3 to achieve sleeve connection with the inner wall of the connecting ring 3, which not only ensures that the connecting plate 7 rotates synchronously with the turbulence ring 1, but also restricts its radial displacement. Multiple connecting rods 8 are evenly hinged around the circumference of the connecting plate 7. The connecting rods 8 are made of high-strength aluminum alloy. One end of each rod is hinged to the connecting plate 7 via a stainless steel hinge, allowing for multi-angle swinging. A second spring 10 is also fixedly connected to the middle of the connecting rod 8. The other end of the second spring 10 is fixedly connected to the connecting plate 7. The second spring 10 is made of stainless steel tension spring. Through the elastic tension of the second spring 10, the scraper 9 can remain attached to the pipe 2 and can always elastically vibrate the inner wall of the pipe 2. Even if there are slight unevennesses in the inner wall of the pipe, the spring's expansion and contraction can compensate for the unevenness and maintain a close fit, ensuring thorough descaling.

[0028] Optionally, the contact surface between the scraper 9 and the inner wall of the pipe 2 is provided with multiple arc-shaped protrusions 11.

[0029] With the aforementioned device, the contact surface between the scraper 9 and the inner wall of the pipe 2 is integrally formed with multiple arc-shaped protrusions 11. The arc-shaped protrusions 11 adopt a semi-circular structure and are evenly distributed along the length of the scraper 9. The arc-shaped protrusions 11 can enhance the contact pressure between the scraper 9 and the inner wall of the pipe 2, forming a point-like impact on the scale adhering to the inner wall of the pipe, improving the descaling efficiency, while reducing the overall contact area between the scraper and the inner wall of the pipe, reducing wear, and extending the service life of the scraper.

[0030] Optionally, multiple sets of descaling components are arranged circumferentially along the connecting ring.

[0031] With the above-mentioned device, multiple sets of descaling components work simultaneously, which can greatly improve the descaling efficiency. Even if the scale on the inner wall of the pipe is thick, it can be gradually removed through the synergistic action of multiple scrapers, ensuring the cleanliness of the inner wall of the pipe.

[0032] Optionally, the fixing buckle 4 has a friction layer 12 internally fixedly connected.

[0033] In this embodiment, the fixing buckle 4 adopts an elastic metal buckle structure and is made of spring steel. The ear plates on both ends of the fixing buckle 4 are connected by bolts, which drives the fixing buckle 4 to tightly clamp the pipe 2. The stability of the fixing buckle 4 can be increased by setting up a friction layer 12.

[0034] Optionally, the connecting ring 3 is also provided with a positioning groove 13 corresponding to the pipe 2.

[0035] With the above-described device, the two end faces of the connecting ring 3 are provided with positioning grooves 13 corresponding to the pipe 2. The depth and inner diameter of the positioning grooves 13 are adapted to the pipe 2. During assembly, the end of the pipe 2 is aligned with the positioning groove 13 and inserted, which can quickly achieve precise positioning of the pipe 2 and the connecting ring 3, avoiding assembly misalignment that could cause malfunction of the device. The inner wall of the positioning groove 13 is also provided with an annular sealing gasket. The sealing gasket is made of silicone material with an appropriate thickness, which can enhance the sealing between the pipe 2 and the connecting ring 3 and prevent fluid leakage.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
