Description

Technical Field

[0001] This utility model relates to the field of electromagnetic scale inhibition technology, specifically to an external electromagnetic scale inhibition device for steam boiler tubes. Background Technology

[0002] Electromagnetic scale inhibitors detect the thickness of scale buildup in pipes by generating a changing magnetic field within the pipe and utilizing the principle of electromagnetic induction. When the alternating current in the transmitting coil generates an alternating magnetic field within the pipe, the receiving coil detects the change in the electromagnetic field. If there is scale buildup in the pipe, eddy currents will be generated at the scale locations. These eddy currents will weaken the magnetic field within the pipe, thereby altering the signal received by the receiving coil. By detecting this signal change, the electromagnetic scale inhibitor can determine the scale buildup situation within the pipe. Therefore, an external electromagnetic scale inhibitor device for steam boiler pipes is needed.

[0003] When operators perform electromagnetic descaling on steam boiler pipes, they often use corresponding external electromagnetic scale inhibition devices. Although existing devices can achieve the purpose of electromagnetic scale inhibition, they often require manual installation in actual use, which may reduce installation efficiency. In addition, the fixing method of the device is limited and the stability is not good. Utility Model Content

Although existing devices can achieve the purpose of electromagnetic scale inhibition, they often require manual installation in actual use, which may reduce installation efficiency. In addition, the fixing method of the device is singular and the firmness is not good.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an external electromagnetic scale inhibitor device for steam boiler tubes, comprising a mounting plate, an electromagnetic scale inhibitor fixedly mounted on the top of the mounting plate, strip grooves on both sides of the bottom of the mounting plate, round rods fixedly mounted inside the strip grooves, connecting rods movably sleeved on the surface of the round rods, toothed plates fixedly mounted on the bottom of the connecting rods, vertical plates fixedly mounted on the bottom of the toothed plates, a movable ring fixedly mounted on the bottom of the vertical plates, a standing plate fixedly mounted on the bottom of the mounting plate, a fixing ring fixedly mounted on the bottom of the standing plate, and a square groove on one side of the standing plate.

[0006] Preferably, clamping plates are fixedly installed on both sides of the bottom of the mounting plate, and a rotating rod is rotatably installed between the clamping plates. Gears are fixedly sleeved on both sides of the rotating rod, and the outer surface of the gears meshes with the outer surface of the gear plate. A motor is fixedly installed on one side of the clamping plate, and the output end of the motor passes through the clamping plate and is fixedly connected to one side of the rotating rod.

[0007] Preferably, a movable plate is fixedly installed at the bottom of the fixed ring, and a fixed plate is fixedly installed at the bottom of the movable ring, with a round hole at one end of both the movable plate and the fixed plate.

[0008] Preferably, a horizontal plate is fixedly installed at one end of the movable plate, and a sliding groove is provided at the top of the horizontal plate. A lead screw is rotatably installed inside the sliding groove, and a sliding sleeve is threaded onto the surface of the lead screw.

[0009] Preferably, a handle is rotatably mounted on one end of the horizontal plate, and one end of the handle passes through the horizontal plate and is fixedly connected to one end of the lead screw.

[0010] Preferably, a movable rod is fixedly installed on the top of the sliding sleeve, and a screw is fixedly installed on one end of each movable rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In daily use, the operator places the pipe under the mounting plate and on the inner surface of the fixing ring, then activates the clamp. The clamp's operation causes the rotating rod to rotate, which in turn drives the gear to rotate. The gear then drives the toothed plate to slide, which in turn drives the connecting rod to slide inside the strip groove and on the surface of the round rod. Simultaneously, the toothed plate drives the vertical plate to slide, which in turn drives the moving ring to slide until the inner surface of the moving ring is placed on the outer surface of the pipe, at which point the electromagnetic scale inhibitor can be installed.

[0013] This electromagnetic scale inhibitor for steam boiler tubes, during daily use, involves rotating the handle when the moving ring and fixed ring are closed. The rotating handle causes the lead screw to rotate, which in turn causes the sliding sleeve to slide inside the sliding groove. The sliding sleeve then causes the moving rod to slide, which in turn causes the screw to slide until the screw is positioned inside the round hole. Finally, bolts are used to connect the moving plate and the fixed plate, thereby improving the stability of the connection between the moving ring and the fixed ring. Attached Figure Description

[0024] Please see Figure 1-8This utility model provides a technical solution: an external electromagnetic scale inhibition device for steam boiler pipes, including a mounting plate 1. An electromagnetic scale inhibitor 2 is fixedly installed on the top of the mounting plate 1. The electromagnetic scale inhibitor 2 can perform electromagnetic scale removal on the pipes. Both sides of the bottom of the mounting plate 1 have strip-shaped grooves 3. A round rod 4 is fixedly installed inside each strip-shaped groove 3. A connecting rod 5 is movably sleeved on the surface of each round rod 4. The inner surface of the connecting rod 5 and the outer surface of the round rod 4 are both smooth, allowing the connecting rod 5 to slide more smoothly inside the round rod 4 and reducing jamming. A toothed plate 6 is fixedly installed at the bottom of each connecting rod 5. When the toothed plate 6 slides, it causes the connecting rod 5 to slide inside the strip-shaped groove 3 and on the surface of the round rod 4. A vertical plate 7 is fixedly installed at the bottom of the toothed plate 6. When the toothed plate 6 slides, it causes the vertical plate 7 to slide. A movable ring 8 is fixedly installed at the bottom of the vertical plate 7. When the vertical plate 7 slides, it will cause the moving ring 8 to slide. The bottom of the mounting plate 1 is fixedly mounted with a vertical plate 9, and the bottom of the vertical plate 9 is fixedly mounted with a fixed ring 10. The fixed ring 10 is adapted to the moving ring 8, and a square groove 11 is opened on one side of the vertical plate 9. The square groove 11 is adapted to the toothed plate 6. The bottom two sides of the mounting plate 1 are fixedly mounted with clamping plates 12. A rotating rod 13 is rotatably mounted between the clamping plates 12. Gears 14 are fixedly sleeved on both sides of the surface of the rotating rod 13. When the rotating rod 13 rotates, it will drive the gears 14 to rotate. The outer surface of the gears 14 meshes with the outer surface of the toothed plate 6. When the gears 14 rotate, they will drive the toothed plate 6 to slide. A motor 15 is fixedly mounted on one side of the clamping plate 12, and the output end of the motor 15 passes through the clamping plate 12 and is fixedly connected to one side of the rotating rod 13. When the motor 15 runs, it will cause the rotating rod 13 to rotate.

[0025] A movable plate 16 is fixedly installed at the bottom of the fixed ring 10, and a fixed plate 17 is fixedly installed at the bottom of the movable ring 8. When the movable ring 8 slides, it will cause the fixed plate 17 to slide. Both the movable plate 16 and the fixed plate 17 have a round hole 18 at one end, which is adapted to the screw 25. A horizontal plate 19 is fixedly installed at one end of the movable plate 16. A groove 20 is formed at the top of the horizontal plate 19. A lead screw 21 is rotatably installed inside the groove 20, and a sliding sleeve 22 is threaded onto the surface of the lead screw 21. When the rod 21 rotates, it causes the sliding sleeve 22 to slide inside the sliding groove 20. A handle 23 is rotatably installed at one end of the horizontal plate 19, and one end of the handle 23 passes through the horizontal plate 19 and is fixedly connected to one end of the lead screw 21. When the handle 23 rotates, it causes the lead screw 21 to rotate. A moving rod 24 is fixedly installed at the top of the sliding sleeve 22, and a screw 25 is fixedly installed at one end of the moving rod 24. When the sliding sleeve 22 slides, it causes the moving rod 24 to slide, which in turn causes the screw 25 to slide.

[0026] Working principle: First, the operator places the pipe below the mounting plate 1 and on the inner surface of the fixing ring 10. Then, the clamping plate 12 is activated. The operation of the clamping plate 12 causes the rotating rod 13 to rotate. Subsequently, the rotating rod 13 drives the gear 14 to rotate. At this time, the gear 14 drives the toothed plate 6 to slide. The toothed plate 6 then drives the connecting rod 5 to slide inside the strip groove 3 and on the surface of the round rod 4. At the same time, the toothed plate 6 drives the vertical plate 7 to slide. The vertical plate 7 then drives the moving ring 8 to slide until the inner surface of the moving ring 8 is placed on the pipe. On the outer surface, the electromagnetic scale inhibitor 2 can be installed. Then, when the moving ring 8 and the fixed ring 10 are closed, the handle 23 is rotated. When the handle 23 rotates, it will drive the lead screw 21 to rotate. Then the lead screw 21 will drive the sliding sleeve 22 to slide inside the sliding groove 20. At this time, the sliding sleeve 22 will drive the moving rod 24 to slide. Then the moving rod 24 will drive the screw 25 to slide until the screw 25 is placed inside the round hole 18. Then, the moving plate 16 and the fixed plate 17 are connected with bolts to improve the connection firmness.
