Description

Technical Field

[0001] The invention relates to the technical field of pipeline heaters, in particular to a heating device for pipelines. Background Art

[0002] In industrial production and daily life, pipe heaters are key equipment and are widely used in the heating and heat preservation of various fluid media. These heaters generate heat through internal heating elements and transfer heat energy to the fluid flowing through the pipe to achieve the purpose of heating or maintaining temperature stability. However, during long-term use, due to factors such as impurities, sediments, and by-products generated by chemical reactions in the fluid, dirt and sediments gradually accumulate inside the pipe heater.

[0003] Most existing pipe heaters adopt a single-tube structure, that is, the heating element is directly installed or embedded in a single pipe. Although this design is simple in structure and low in manufacturing cost, it has obvious shortcomings in terms of maintenance and cleaning. Due to the limited space inside the pipe and the obstruction of the heating element, traditional cleaning methods such as high-pressure water gun flushing or chemical solvent immersion are difficult to implement effectively. Once the dirt inside the pipe accumulates to a certain extent, it will not only seriously affect the heating efficiency and increase energy consumption, but may also cause serious problems such as pipe blockage and heating element damage.

[0004] Faced with this challenge, the current common solution is to completely disassemble the heater for cleaning. However, this method is not only time-consuming and labor-intensive, but also increases downtime and maintenance costs. Summary of the invention

Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0029] See also Figure 1-8 , an embodiment provided by the present invention:

[0030] A heating device for a pipeline comprises an external pipe 2, both ends of which are connected to a junction box 1 and a movable cover 9 through flanges, a fixed shell 511 is fixedly installed on both sides of the inner wall of the external pipe 2, and the fixed shell 511 is provided with a movable mechanism, and one end of the movable mechanism is connected to an inner tube 8, two sets of movable grooves 512 are provided at both upper and lower ends of the external pipe 2, and the inner walls of the two sets of movable grooves 512 are movably engaged with a limiting slide 811, the limiting slide 811 is fixedly connected to the inner tube 8, and the outer surface of the inner tube 8 is provided with two sets of through grooves 812, and the outer surface of the junction box 1 is provided with a plurality of movable grooves 512. A wiring port 6 is provided on the surface, and one end of the wiring box 1 is connected to multiple groups of heating tubes 111, and the multiple groups of heating tubes 111 are arranged in the inner wall of the inner tube 8. Multiple groups of guide plates 112 are fixedly installed on the outer surface of the multiple groups of heating tubes 111. Two groups of connecting tubes 7 are fixedly installed on the outer surface of the top end of the external tube 2, and the inner walls of the two groups of connecting tubes 7 are both provided with threads. The inner walls of the connecting tubes 7 are respectively movably installed with water inlet pipes 3 and water outlet pipes 4, and the bottom ends of the water inlet pipes 3 and the water outlet pipes 4 are through-connected to the bottom end of the through groove 812, and the outer surfaces of the water inlet pipes 3 and the water outlet pipes 4 are both wrapped with rubber.

[0031] Furthermore, two groups of support seats 5 are fixedly installed on the outer surface of the bottom end of the external tube 2, and both ends of the two groups of support seats 5 are triangular. The triangular support seats 5 provide more stable support and enhance the anti-overturning ability of the entire device, especially when subjected to fluid pressure and thermal stress generated when the heating element is working.

[0032] Furthermore, a rubber ring 813 is fixedly mounted on the outer surface of one end of the inner tube 8. The use of the rubber ring 813 enhances the sealing between the inner tube 8 and other components, prevents fluid leakage, and thus improves the overall efficiency and safety of the equipment.

[0033] Furthermore, a sealing ring 211 is fixedly mounted on the inner wall of one side of the external pipe 2, and a groove 212 is formed on the outer surface of the sealing ring 211. The groove 212 cooperates with the rubber ring 813 to ensure that the fluid does not leak from the connection.

[0034] Furthermore, a plurality of operating rods 311 are fixedly installed on the outer surfaces of the top ends of the water inlet pipe 3 and the water outlet pipe 4. The design of the operating rods 311 allows the user to more easily rotate and disassemble the water inlet pipe and the water outlet pipe, thereby simplifying the cleaning and maintenance process. A filter screen 312 is fixedly installed on the inner walls of the water inlet pipe 3 and the water outlet pipe 4. The use of the filter screen 312 can prevent impurities from entering the interior of the device, thereby extending the service life and performance of the equipment.

[0035] Furthermore, the movable mechanism includes two groups of fixed seats 611, and the outer surfaces of the two groups of fixed seats 611 are provided with annular grooves, a screw rod 613 is movably installed in the annular groove, and one end of the screw rod 613 is connected to a motor 612, the motor 612 is fixedly connected to the fixed seat 611, a sliding seat 614 is movably installed on the outer surface of the screw rod 613, and one side of the sliding seat 614 is connected to a first connecting block 711, the first connecting block 711 is fixedly connected to the second connecting block 712 through the screw rod 713, and the second connecting block 712 is fixedly connected to the outer surface of the inner bile tube 8, and the screw rod 613 is driven by the motor 612 to operate, so that people can easily disassemble the inner bile tube 8 without large-scale disassembly of the entire device.

[0036] Furthermore, a protective plate 714 is fixedly installed on one side of the inner wall of the fixed shell 511, and a limiting groove is provided on the outer surface of the protective plate 714, in which the first connecting block 711 is movably engaged, and the limiting groove ensures the stability and accuracy of the first connecting block 711 during movement.

[0037] Working principle: First, water is introduced into the inner tube 8 through the water inlet pipe 3. The design of the water inlet pipe 3 and the water outlet pipe 4 allows the fluid to flow smoothly during the heating process, while the rubber layer wrapped on their outer surface provides additional sealing and durability. Next, an external power supply is connected through the junction box 1, so that the multiple sets of heating tubes 111 start working to heat the water inside the inner tube 8. The multiple sets of guide plates 112 fixedly installed on the outer surface of the heating tube 111 can optimize the water flow path and improve the heating efficiency and uniformity.

[0038] When the heating is completed, the hot water is discharged through the water outlet pipe 4 for subsequent use. During the entire heating process, the two sets of connecting pipes 7 fixedly installed on the outer surface of the top of the external pipe 2 serve as interfaces for the inlet and outlet pipes. The threaded design of the inner wall ensures a firm connection between the inlet pipe 3 and the outlet pipe 4 and the connecting pipe 7 to prevent leakage. When the inner wall of the inner tube 8 needs to be cleaned, the inlet pipe 3 and the outlet pipe 4 are first rotated, and the flexible snap-fit ​​design between them and the through groove 812 on the outer surface of the inner tube 8 can be used to easily remove the inlet pipe 3 and the outlet pipe 4 from the inner tube 8. This step simplifies the preparation work before cleaning and avoids the cumbersome process of overall disassembly of the traditional heater.

[0039] Next, open the flange, remove the movable cover 9, and expose the outside of the inner tube 8. At this time, by driving the motor 612, the screw rod 613 is rotated. The threaded fit between the screw rod 613 and the sliding seat 614 enables the sliding seat 614 to move left and right along the screw rod 613. The sliding seat 614 is fixedly connected to the outer surface of the inner tube 8 through the first connecting block 711 and the second connecting block 712. Therefore, as the sliding seat 614 moves, the inner tube 8 will also move inside the external tube 2.

[0040] When the inner tube 8 is close to the outlet of the external tube 2, the first connection block 711 and the second connection block 712 can be easily separated by rotating the screw 713, so that the inner tube 8 can be completely removed from the external tube 2. This design not only facilitates cleaning the inner wall of the inner tube 8, but also allows replacement of the spare inner tube 8 during the cleaning process, thereby greatly reducing downtime and improving equipment utilization.

[0041] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
