Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic heater technology, specifically a novel high-strength and corrosion-resistant electromagnetic heater. Background Technology

[0002] An electromagnetic heater, also known as an induction heater or electromagnetic induction heater, is a device that converts electrical energy into heat energy using the principle of electromagnetic induction. It generates eddy currents within a conductive material through an alternating magnetic field, directly heating the material itself rather than through traditional heat conduction or convection. To improve the corrosion resistance of the heating element inside the heater, a corrosion-resistant material is typically coated onto the inner wall of the heating element.

[0003] Existing electromagnetic heaters typically contain a heating element, with acidic solutions flowing through it via pipes connected to both ends. The interior of the heating element contains suspended particles, sediments, and microbial deposits. These microorganisms secrete biofilms that adsorb impurities, forming an adhesive layer. Regular cleaning of the heating element's interior is necessary. However, existing heating elements are generally fixed to the casing using adhesive or bolts, making cleaning and disassembly inconvenient. Summary of the Invention

[0004] The purpose of this invention is to provide a novel high-strength and corrosion-resistant electromagnetic heater, which has high corrosion resistance and the heating tube is easy and quick to assemble and disassemble, facilitating regular cleaning of the inside of the heating tube.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A novel high-strength, corrosion-resistant electromagnetic heater is provided, comprising a housing. Multiple movable grooves are provided inside the housing. Multiple clamping grooves are provided on the inner wall of the housing, and these grooves are connected to the movable grooves. A lead screw is movably connected to the inner wall of the movable groove. One end of the lead screw penetrates the housing and is fixedly connected to a driven gear. A movable block is threadedly connected to the outer wall of the lead screw. One end of the movable block is located inside the movable groove. Connecting rods are movably connected to both outer walls of the movable block. Multiple clamping plates are provided inside the housing. Fixed blocks are fixedly connected to both ends of the outer walls of the multiple clamping plates. The opposing surfaces of two adjacent connecting rods are movably connected to the outer walls of the fixed blocks on the same side. A heating tube is clamped in the middle of the multiple clamping plates. A rotating groove is provided at the front end of the housing. A gear ring is installed inside the rotating groove. A limiting ring is fixedly connected to the outer wall of the gear ring. A limiting groove is provided on the inner wall of the rotating groove, and the limiting ring is located inside the limiting groove.

[0006] Optionally, the inner wall of the heating tube is coated with polytetrafluoroethylene, the driven gear is located inside the rotating groove, and the inner wall of the gear ring meshes with the outer walls of the plurality of driven gears.

[0007] Optionally, the outer wall of the gear ring is fixedly connected with a lever, and the number of levers is multiple.

[0008] Optionally, the outer wall of the housing is wound with a coil, which has two ends.

[0009] Optionally, a positioning ring is fixedly connected to the outer wall of one end of the heating tube, and a positioning block is fixedly connected to the outer wall of the positioning ring. The number of positioning blocks is multiple. A positioning groove is opened on the inner wall of one end of the outer shell. The number of positioning grooves is multiple. The multiple positioning blocks are respectively located inside the multiple positioning grooves.

[0010] Optionally, the bottom of the housing is provided with a base plate, and both ends of the base plate are fixedly connected with support plates. The top of both support plates is provided with support grooves, and the top of the base plate on the same side as the gear ring is provided with a groove, which is connected to the support groove on the left side.

[0011] Optionally, the bottom ends of the outer casing are located inside the support grooves opened in the two trays, and the lever is located inside the groove.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the initial state of this utility model, multiple clamping plates hold and fix the heating tube inside the outer shell, and both ends of the heating tube are threadedly connected to guide tubes. When the heating tube needs to be cleaned, the gear ring is rotated. Because the inner wall of the gear ring meshes with the outer wall of multiple driven gears, the multiple driven gears and the lead screws connected to them rotate synchronously when the gear ring rotates. This causes the two moving blocks threaded to the lead screws to move relative to each other. When the two moving blocks move relative to each other, they drive one end of the connecting rods movably connected to both sides of the moving blocks to move. The other ends of the two connecting rods movably connected to the two moving blocks pull the clamping plates to disengage them from the heating tube. Then, the heating tube can be cleaned. The heating element can be quickly pulled out from inside the outer casing, allowing for easy cleaning of its inner wall. This convenient and quick assembly / disassembly facilitates regular cleaning of the heating element's inner wall, extending its lifespan. During installation, one end of the heating element is inserted into the casing through the end with the positioning groove. Multiple positioning blocks align with these grooves. Once all positioning blocks are fully inserted, the gear ring rotates in opposite directions, causing two moving blocks to move in opposite directions. This pushes the other end of the connecting rod towards the center of the heating element. Ultimately, the multiple clamping plates work together to hold the heating element in the center, making installation quick and easy. Attached Figure Description

[0027] Reference Figure 1-7This invention provides a novel high-strength, corrosion-resistant electromagnetic heater. The novel high-strength, corrosion-resistant electromagnetic heater includes a housing 1. Multiple movable grooves 2 are formed inside the housing 1. Multiple clamping grooves 3 are formed on the inner wall of the housing 1 and are connected to the movable grooves 2. A lead screw 4 is movably connected to the inner wall of the movable groove 2. One end of the lead screw 4 passes through the housing 1 and is fixedly connected to a driven gear 5. A movable block 6 is threadedly connected to the outer wall of the lead screw 4. One end of the movable block 6 is located inside the movable groove 2. Connecting rods 7 are movably connected to both outer walls of the movable block 6. Multiple clamping plates 8 are provided inside the housing 1. The outer walls of the multiple clamping plates 8 are connected at both ends... Each component is fixedly connected to a fixing block 9. The opposite faces of two adjacent connecting rods 7 are movably connected to the outer walls of the fixing blocks 9 on the same side. The heating tube 10 is clamped in the middle of multiple clamping plates 8. A rotating groove 11 is opened at the front end of the outer shell 1. A gear ring 12 is installed inside the rotating groove 11. A limit ring 13 is fixedly connected to the outer wall of the gear ring 12. A limit groove 14 is opened on the inner wall of the rotating groove 11. The limit ring 13 is located inside the limit groove 14. In the initial state, the multiple clamping plates 8 clamp and fix the heating tube 10 inside the outer shell 1, and the two ends of the heating tube 10 are respectively threaded to guide tubes. When the heating tube 10 needs to be cleaned, the gear ring 12 is rotated. Because the inner wall of the gear ring 12 meshes with the outer walls of multiple driven gears 5, when the gear ring 12 rotates, the multiple driven gears 5 and the lead screws 4 connected to them rotate synchronously. This causes the two moving blocks 6, which are threaded to the lead screws 4, to move relative to each other. When the two moving blocks 6 move relative to each other, they drive one end of the connecting rods 7, which are movably connected to both sides of the moving blocks 6, to move. The other ends of the two connecting rods 7, which are movably connected to the two moving blocks 6, together pull the clamping plate 8 to disengage it from the heating tube 10. Then the heating tube 10 can be pulled out from the inside of the outer shell 1. This allows for quick extraction of the heating tube 10 from the inside of the outer shell 1, and allows for cleaning of the inner wall of the heating tube 10. The heating tube 10 is easy and quick to install and remove, and the inner wall of the heating tube 10 can be cleaned regularly, extending the service life of the heating tube 10. When installing the heating tube 10, insert one end of the heating tube 10 into the interior of the outer shell 1 from the end with the positioning groove 19, so that multiple positioning blocks 18 correspond to multiple positioning grooves 19. After multiple positioning blocks 18 are fully inserted into the positioning grooves 19, rotate the gear ring 12 in the opposite direction. Similarly, make the two moving blocks 6 move in opposite directions, so that the other end of the connecting rod 7 pushes the clamping plate 8 to move towards the center of the heating tube 10. Finally, multiple clamping plates 8 work together to clamp the heating tube 10 in the center, making the installation of the heating tube 10 convenient and quick.

[0028] In another embodiment of this utility model, please refer to Figure 2The inner wall of the heating tube 10 is coated with polytetrafluoroethylene (PTFE). PTFE is resistant to almost all chemical media and is suitable for pipelines containing strong acids, strong alkalis, or organic solvents, thus improving the corrosion resistance of the heating tube 10. The driven gear 5 is located inside the rotating groove 11, and the inner wall of the gear ring 12 meshes with the outer walls of multiple driven gears 5.

[0029] In another embodiment of this utility model, please refer to Figure 1 A lever 15 is fixedly connected to the outer wall of the gear ring 12 to facilitate the rotation of the gear ring 12, and there are multiple levers 15. A coil 16 is wound around the outer wall of the outer shell 1, and the coil 16 has two ends.

[0030] In another embodiment of this utility model, please refer to Figures 1 to 5 A positioning ring 17 is fixedly connected to the outer wall of one end of the heating tube 10. A positioning block 18 is fixedly connected to the outer wall of the positioning ring 17. There are multiple positioning blocks 18. A positioning groove 19 is opened on the inner wall of one end of the outer shell 1. There are multiple positioning grooves 19. Multiple positioning blocks 18 are located inside multiple positioning grooves 19. After the heating tube 10 is inserted into the outer shell 1, its position can be limited so that the position of the heating tube 10 is fixed after it is inserted into the outer shell 1.

[0031] In another embodiment of this utility model, please refer to Figure 2 and Figure 3 The bottom of the outer casing 1 is provided with a base plate 20, and both ends of the base plate 20 are fixedly connected with support plates 21. The top of the two support plates 21 is provided with a support groove 22. The top of the base plate 20 on the same side as the gear ring 12 is provided with a groove 23. The groove 23 is connected to the support groove 22 on the left side. The bottom ends of the outer casing 1 are respectively located inside the support grooves 22 opened in the two support plates 21.
