Description

Technical Field

[0001] This utility model belongs to the field of condenser technology, specifically relating to a condenser scale removal component and its descaling device. Background Technology

[0002] Condensers, as an important heat exchange device, are widely used in many fields such as power, chemical industry, and refrigeration.

[0003] Condensers are mainly used in steam turbine power units and are divided into two types: water-cooled condensers and air-cooled condensers. In existing condensers, solid impurities accumulate on the walls of the condenser tubes due to water cooling. These various solid impurities gradually accumulate on the condenser tube walls, forming scale. Currently, chemical cleaning methods are mostly used to clean the scale on the inner walls of the condenser tubes. This cleaning method is not only costly but also requires a long cleaning time. Utility Model Content

[0004] Purpose of the utility model: To provide a condenser scale removal component and its descaling device, which solves the above-mentioned problems existing in the prior art.

[0005] Technical solution: A condenser descaling device includes a cylindrical shell, which is a hollow structure with one open end. An adjusting assembly is located inside the cylindrical shell. The adjusting assembly is partially connected to at least three sets of moving rods, which penetrate the sidewall of the cylindrical shell. A scraping component is installed at the end of each set of moving rods furthest from the adjusting assembly. The adjusting assembly is used to adjust the reciprocating movement of the moving rods against the sidewall of the cylindrical shell and to adjust the scraping component's movement away from or near the cylindrical shell. A limiting assembly is installed at the opening of the cylindrical shell, and the limiting assembly's operability limits and blocks the adjusting assembly.

[0006] Preferably, the adjusting assembly includes an annular internal gear, which is slidably installed inside the cylindrical shell. The annular internal gear is internally meshed with a number of circular gears equal to the number of moving rods. One end of each circular gear is rotatably mounted on the limiting assembly, and the other end protrudes from the annular internal gear and meshes with the moving rod. A limiting post is installed on the side wall of the circular gear away from the moving rod. The limiting post is inserted into the limiting assembly, and the limiting post and the limiting assembly cooperate with each other to limit the rotation of the circular gear.

[0007] Preferably, the limiting component includes a mounting base shell, which is installed at the opening of the cylindrical shell. The mounting base shell has an arc-shaped slide rail along its axial direction, and the limiting post passes through the arc-shaped slide rail. The mounting base shell has a mounting cavity along the edge of the arc-shaped slide rail, and a plurality of limiting parts are circumferentially arrayed in the mounting cavity. The movable end of the limiting part is operably inserted into the arc-shaped slide rail, and the limiting part is used to block the limiting post.

[0008] Preferably, the limiting part includes a return spring, one end of which is connected to the inner wall of the mounting cavity, and the other end of which is connected to a limiting block. The end of the limiting block near the return spring is inserted into the inner wall of the mounting cavity, and the other end of which is inserted into the arc-shaped slide.

[0010] Preferably, the system further includes connecting guide blocks in the same number as the moving rods, the guide blocks being installed inside the cylindrical shell at the end, and the moving rods sliding through the guide blocks.

[0011] A condenser descaling device includes a mounting base, on which a drive motor is mounted. The output end of the drive motor is connected to a transmission shaft. A sleeve is fitted around the transmission shaft. One end of the sleeve is mounted on the mounting base, and the other end of the sleeve is fitted with a mounting ring. The transmission end of the transmission shaft is connected to a scraping component, wherein the scraping component is the aforementioned condenser scale scraping component. The mounting ring is slidably connected to the scraping component. A plurality of high-pressure nozzles are circumferentially arrayed on the sidewall of the mounting ring. A water pump is mounted on the top of the mounting base, and the water pump is connected to the high-pressure nozzles via a hose.

[0012] Beneficial effects: This utility model relates to a condenser scale removal component and its descaling device. By adjusting the scraping component to move away from or closer to the cylindrical shell, it can be adapted to condenser tubes of different diameters, thus enabling scale removal treatment of condenser tubes of various diameters.

[0013] Secondly, by driving the scraper to rotate inside the condenser tube by the drive motor, the scale remaining in the condenser tube can be quickly removed. In conjunction with the high-pressure nozzle, the inner wall of the condenser tube is sprayed, thereby achieving a secondary cleaning treatment of the condenser tube, which improves the cleaning effect. The combination of the scraper component and the high-pressure nozzle reduces equipment and operating costs. Attached Figure Description

[0024] like Figures 1 to 6 As shown, this utility model provides a technical solution: a condenser descaling device, including a cylindrical shell 1, as shown in the figure. Figure 3 As shown, the cylindrical shell 1 is a hollow structure with one open end. An adjusting assembly 2 is located inside the cylindrical shell 1. The adjusting assembly 2 is partially connected to at least three sets of moving rods 3. In this embodiment, three sets of straight racks are used as the three sets of moving rods 3. The moving rods 3 penetrate the side wall of the cylindrical shell 1. A guide block 6 is slidably sleeved on each moving rod 3. The guide block 6 is installed at the inner end of the cylindrical shell 1, and guides the moving rod 3 in the direction of movement. A scraping assembly 4 is installed at the end of each moving rod 3 away from the adjusting assembly 2. The scraping assembly 4 includes an arc-shaped plate 41, which is installed at the moving end of the moving rod 3. The arc-shaped plate 41 is located on the outer wall of the end of the moving rod 3 away from the moving rod 3. A connecting plate 42 is installed, which is parallel to the moving rod 3. A scraper 43 is installed at an angle on the end of the connecting plate 42 away from the arc plate 41. The adjusting component 2 is used to adjust the moving rod 3 to reciprocate on the side wall of the cylindrical shell 1 and adjust the scraping component 4 to move away from or closer to the cylindrical shell 1, so as to adapt to condenser tubes of different diameters and realize the descaling treatment of condenser tubes of various diameters. A limiting component 5 is installed at the opening of the cylindrical shell 1. The limiting component 5 operates to limit and block the adjusting component 2, so as to limit and fix the scraping component 4 in a specific position, so as to avoid the scraping component 4 from moving due to external force during the scraping process, which would affect the scraping effect on the inner wall of the condenser tube.

[0025] In a further embodiment, such as Figure 3 and 4 As shown, the adjusting component 2 includes an annular internal gear 21, which is slidably installed inside the cylindrical shell 1. The annular internal gear 21 is internally meshed with a number of circular gears 22, the same number as the moving rod 3. One end of each circular gear 22 is rotatably mounted on the limiting component 5, and the other end protrudes from the annular internal gear 21 and meshes with the moving rod 3. A limiting post 23 is installed on the side wall of the circular gear 22 away from the moving rod 3. The limiting post 23 is inserted into the limiting component 5, and the limiting post 23 meshes with... The limiting components 5 cooperate with each other to limit the rotation of the sprocket 22. That is, when it is necessary to adjust the scraping component 4 to a suitable position on the inner wall of the condenser, an external force is applied to the limiting post 23, which drives the annular inner gear 21 to rotate. With the cooperation of the annular inner gear 21 and the sprocket 22, the moving rod 3 is moved, so that the scraping component 4 can be adjusted to abut against the inner wall of the condenser. By limiting the limiting post 23 through the limiting components 5, the scraping component 4 can be kept in abutting against the inner wall of the condenser, so as to achieve the cleaning treatment of scale inside the condenser.

[0026] In a further embodiment, such as Figure 5 As shown, the limiting component 5 includes a mounting base 51, which is installed at the opening of the cylindrical shell 1. The mounting base 51 has an arc-shaped slide rail 52 along its axial direction. The limiting post 23 passes through the arc-shaped slide rail 52. The mounting base 51 has a mounting cavity 53 along the edge of the arc-shaped slide rail 52. A plurality of limiting parts are circumferentially arrayed within the mounting cavity 53. The movable end of each limiting part is operably inserted into the arc-shaped slide rail 52. Each limiting part includes a reset component. Spring 54, one end of the return spring 54 is connected to the inner wall of the mounting cavity 53, and the other end of the return spring 54 is connected to the limiting block 55. The end of the limiting block 55 near the return spring 54 is inserted into the inner wall of the mounting cavity 53, and the other end is inserted into the arc-shaped slide 52. That is, when the limiting post 23 moves, an external force is applied to the limiting block 55 to squeeze the return spring 54, so that the limiting block 55 moves into the mounting cavity 53, and the position of the limiting post 23 in the arc-shaped slide is adjusted.

[0027] A condenser descaling device includes a mounting base 7, on which a drive motor is mounted. The output end of the drive motor is connected to a transmission shaft 8. A sleeve 9 is sleeved around the transmission shaft 8. One end of the sleeve 9 is mounted on the mounting base 7, and the other end of the sleeve 9 is mounted on a mounting ring 10. The transmission end of the transmission shaft 8 is connected to a scraper, wherein the scraper is the aforementioned condenser scale scraper. The mounting ring 10 is slidably connected to the scraper. Several high-pressure nozzles 11 are circumferentially arrayed on the side wall of the mounting ring 10. A water pump 12 is mounted on the top of the mounting base 7. The water pump 12 is connected to the high-pressure nozzles 11 through a hose. The drive motor drives the scraper to rotate inside the condenser tube, which can quickly remove the scale remaining in the condenser tube. In conjunction with the high-pressure nozzles 11, the inner wall of the condenser tube is sprayed, thereby achieving a secondary cleaning treatment of the condenser tube and improving the cleaning effect. The scraper assembly 4 combined with the high-pressure nozzles 11 reduces equipment and operating costs.
