[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figure 1 - Figure 3, the utility model provides an embodiment: an anti-corrosion heating pipe that is easy to disassemble and assemble, including a connecting pipe 1, the outer wall of the connecting pipe 1 is slidably connected to a mounting seat 2, the outer wall of the connecting pipe 1 is rotatably connected to a rotating sleeve 3, the interior of the mounting seat 2 is slidably connected to a connecting rod 4, one side of the outer wall of the connecting rod 4 is fixedly connected to a telescopic rod 5, one end of the telescopic rod 5 is fixedly connected to the interior of the mounting seat 2, the outer wall sleeve of the telescopic rod 5 is provided with a spring 6, one end of the spring 6 is fixedly connected to the outer wall of the connecting rod 4, the other end of the spring 6 is fixedly connected to the interior of the mounting seat 2, the interior of the mounting seat 2 is rotatably connected to a rotating rod 7, the outer wall of the rotating rod 7 is fixedly connected to a push plate 8, the other side of the outer wall of the connecting rod 4 is fixedly connected to a card block 9, the outer wall of the rotating sleeve 3 is fixedly connected to a positioning block 10, the outer wall of the positioning block 10 is slidably connected to the interior of the mounting seat 2, and a sealing component is provided inside the rotating sleeve 3;

[0026] Specifically, firstly, the electrode connection end 14 is passed through the central hole of the mounting seat 2 to ensure that it is aligned with and fixed to the corresponding interface inside the mounting seat 2, and the positioning block 10 is inserted along the preset track of the mounting seat 2 to ensure that it can rotate freely inside the mounting seat 2. The rotating sleeve 3 is rotated to drive the positioning block 10 to rotate inside the mounting seat 2, which will apply pressure to the card block 9. As the positioning block 10 rotates, the card block 9 slides inside the mounting seat 2 and compresses the spring 16 at the same time. The contraction of the spring 16 will generate thrust. When the card block 9 is pushed to the positioning block 1 0, due to the thrust of spring 16, the block 9 will be tightly locked in the slot, thereby fixing the connecting pipe 1, and then by rotating the rotating rod 7, the push plate 8 can be driven to apply pressure to the connecting rod 4, and the pressure of the push plate 8 can make the connecting rod 4 move, thereby pulling the block 9 out of the internal slot of the positioning block 10. When the block 9 is completely released from the positioning block 10, the connecting pipe 1 can be easily removed, which not only realizes the quick and easy disassembly and assembly of the heating pipe, but also ensures the stability and safety of the connecting pipe 1 during installation.

[0027] Reference Figure 3 The sealing assembly includes a sealing ring 11, the outer wall of the sealing ring 11 is slidably connected to the outer wall of the rotating sleeve 3, the inner wall of the sealing ring 11 is fixedly connected to a telescopic rod 12, one end of the telescopic rod 12 is fixedly connected to the inside of the rotating sleeve 3, and the outer wall of the telescopic rod 12 is provided with a spring 13, one end of the spring 13 is fixedly connected to the inner wall of the sealing ring 11, and the other end of the spring 13 is fixedly connected to the inside of the rotating sleeve 3;

[0028] Specifically, during the installation of the heating tube, when the mounting seat 2 and the rotating sleeve 3 are tightly fitted, the sealing ring 11 is placed between the two. Due to the pressure generated by the fitting, the sealing ring 11 begins to slide inside the rotating sleeve 3, making it fit more closely to the inner wall of the rotating sleeve 3. At the same time, pressure is applied to the spring 13, and the spring 13 begins to shrink. As the spring 13 shrinks, a reverse thrust is generated on the sealing ring 11, making it fit more closely to the mounting seat 2. The gap between the mounting seat 2 and the rotating sleeve 3 is effectively closed, thereby achieving a high-strength sealing effect.

[0029] Reference Figure 4 One end of the connecting tube 1 is fixedly connected to an electrode connecting end 14, the other end of the connecting tube 1 is fixedly connected to a heating tube shell 15, the interior of the heating tube shell 15 is uniformly coated with a ceramic coating 16, the inner wall of the heating tube shell 15 is fixedly connected to a stainless steel layer 17, the inner wall of the stainless steel layer 17 is fixedly connected to an insulating layer 18, the inner wall of the insulating layer 18 is fixedly connected to a filling layer 19, and the inner wall of the filling layer 19 is fixedly connected to a heating wire 20;

[0030] Specifically, the outer wall of the heating tube shell 15 of the heating tube is covered with a uniform ceramic coating 16, which can effectively isolate the corrosive medium in the external environment, thereby protecting the internal heating wire 20 from corrosion. In addition to the ceramic coating 16, there is also a stainless steel layer 17 inside the heating tube shell 15. The stainless steel layer 17 not only enhances the mechanical strength of the entire heating tube, but also further prevents the invasion of corrosive factors in the external environment, thereby enhancing the protective effect on the heating wire 20. In addition, the quartz sand inside the filling layer 19 can absorb or neutralize corrosive substances to protect the heating element from corrosion. Finally, the insulating layer 18 is located between the heating wire 20 and the heating tube shell 15, and is an important barrier to prevent current leakage to the heating tube shell 15 and the external environment. The design and application of multiple protection measures enable the heating tube to maintain stable performance and safety in harsh working environments.

[0031] Working principle: when the corrosion-resistant heating tube is needed, first pass the electrode connecting end 14 through the mounting seat 2, so that the rotating sleeve 3 fits with the mounting seat 2, and insert the positioning block 10 into the interior of the mounting seat 2, and then rotate the rotating sleeve 3, thereby driving the positioning block 10 to rotate inside the mounting seat 2, thereby applying pressure to the card block 9, so that the card block 9 and the connecting rod 4 slide inside the mounting seat 2, and at the same time, the spring 16 is contracted, and then the card block 9 is pushed into the preset card groove inside the positioning block 10 through the thrust generated by the contraction of the spring 16, thereby realizing the installation of the connecting tube 1. When disassembling, it is only necessary to rotate the rotating rod 7 to drive the push plate 8 to apply pressure to the connecting rod 4, and then pull the card block 9 out of the interior of the positioning block 10 through the connecting rod 4, and then the connecting tube 1 can be needed, thereby achieving the effect of disassembly and assembly of the heating tube.

[0032] Secondly, when installing the heating tube, the mounting seat 2 is fitted with the rotating sleeve 3, so that the sealing ring 11 is pressed and slides inside the rotating sleeve 3, and at the same time, pressure is applied to the spring 13 to shrink the spring 13, and then the thrust generated by the shrinkage of the spring 13 pushes the sealing ring 11 to fit with the mounting seat 2, thereby achieving a high-strength seal.

[0033] Finally, the ceramic coating 16 evenly covering the outer wall of the heating tube shell 15 cooperates with the stainless steel layer 17 and the quartz sand filler inside the filling layer 19 to protect the heating wire 20 from corrosion. At the same time, the insulating layer 18 can withstand the high temperature generated by the heating tube during operation, and at the same time has good insulation properties to prevent safety accidents such as electric shock.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
