Description

Technical Field

[0001] This utility model relates to the technical field of constant temperature heat tracing and anti-clogging structures, specifically a constant temperature heat tracing and anti-clogging structure for a microcrystalline wax melting and conveying pipeline. Background Technology

[0002] The constant temperature heating and anti-clogging structure of the microcrystalline wax melting and conveying pipeline mainly adopts a self-regulating electric heating tape combined with a temperature control system. It maintains a constant temperature in the pipeline by automatically adjusting the temperature to prevent the wax from solidifying and clogging. It uses conductive polymer materials such as PTC cores, which increase resistance and reduce power when the temperature rises, thus achieving automatic temperature control.

[0003] As disclosed in the patent announcement CN222559495U, a pipe heat tracing device includes: a planar heating element, a shielding layer, a heat insulation layer, and an explosion-proof shell arranged sequentially from the inside to the outside of the pipe along its radial direction; the planar heating element includes an upper encapsulation layer, a heating layer, a heating base layer, and a lower encapsulation layer arranged sequentially from the inside to the outside of the pipe along its radial direction. The pipe heat tracing device provided by this utility model includes: a planar heating element, a shielding layer, a heat insulation layer, and an explosion-proof shell arranged sequentially from the inside to the outside of the pipe along its radial direction; the planar heating element includes an upper encapsulation layer, a heating layer, a heating base layer, and a lower encapsulation layer arranged sequentially from the inside to the outside of the pipe along its radial direction.

[0004] Although it achieves this, the large contact area between the sheet-like electric heating film and the pipeline allows the generated heat to be directly conducted into the pipeline, which is more advantageous than heating cables. In environments such as oil wells, there is a certain requirement for explosion protection, so setting an explosion-proof shell on the outermost layer of the pipeline heating device can achieve the explosion-proof effect.

[0005] However, this does not solve the problem that existing constant temperature heat tracing and anti-clogging structures are generally not conducive to convenient constant temperature heat tracing of microcrystalline wax molten transport pipelines. The microcrystalline wax inside the pipeline is prone to solidification due to excessively low temperature, causing pipeline blockage and affecting the effect of constant temperature heat tracing and anti-clogging. It is also inconvenient to disassemble the constant temperature heat tracing and anti-clogging structure, affecting the convenience of installation and disassembly of the constant temperature heat tracing and anti-clogging structure. Utility Model Content

[0006] The purpose of this utility model is to provide a constant temperature tracing and anti-clogging structure for a microcrystalline wax melting and conveying pipeline, so as to solve the problems in the background art where the constant temperature tracing and anti-clogging structure is not convenient for the microcrystalline wax melting and conveying pipeline, the microcrystalline wax inside the pipeline is prone to solidification due to low temperature, causing pipeline blockage, which affects the effect of constant temperature tracing and anti-clogging, and the constant temperature tracing and anti-clogging structure is not convenient to disassemble, which affects the convenience of installation and disassembly of the constant temperature tracing and anti-clogging structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a constant temperature heat tracing and anti-clogging structure for a microcrystalline wax melting and conveying pipeline, comprising a left fixed frame and a right fixed frame, wherein the right fixed frame is disposed outside the left fixed frame, and clamping arms are symmetrically arranged between the left and right fixed frames. Each clamping arm is provided with an insulation layer on its exterior. Multiple sets of first springs at equal intervals are installed on the outer wall of each clamping arm near the insulation layer, with one end of each first spring connected to the insulation layer and the other end connected to the clamping arm. A heat-conducting layer is disposed outside the insulation layer, and multiple sets of electric heating tapes at equal intervals are installed on the outer wall of each heat-conducting layer near the insulation layer. The heat tracing cable is connected to the insulation layer, and a temperature sensor is installed on the outer wall of one set of insulation layers. Threaded sleeves are installed on the outer walls of both the left and right fixed frames. Threaded rods are movably installed inside each threaded sleeve, extending to the outside of the threaded sleeve. The threaded sleeve and threaded rod are threadedly connected, and the threaded rod is connected to the clamping arm. Handwheels are installed on the outer wall of the threaded rod on the side away from the threaded sleeve. A left fixed seat is installed at the bottom of the left fixed frame, and a right fixed seat is installed at the bottom of the right fixed frame on the side of the left fixed seat. A flipping shaft is movably installed on the outer wall of the left fixed seat near the right fixed seat, and the left fixed seat is movably connected to the right fixed seat via the flipping shaft.

[0008] Preferably, a limiting seat is installed at the top of the left fixing bracket on the side away from the left fixing seat, and a limiting bracket is installed at the top of the limiting seat.

[0009] Preferably, a connecting seat is installed at the top of the right fixing frame on one side of the limiting seat, and a limiting rod is installed on the outer wall of the connecting seat.

[0010] Preferably, support frames are symmetrically installed on the outer wall of the limiting frame, and sliding rods are slidably installed inside each support frame, with the sliding rods extending into the interior of the limiting frame.

[0011] Preferably, each sliding rod has a pull ring movably mounted on its outer wall, and a fixing block is mounted on the end of the sliding rod away from the pull ring.

[0012] Preferably, the surface of each sliding rod is fitted with a second spring, and one end of the second spring is connected to the fixed block.

[0013] Preferably, the other end of the second spring is connected to the support frame, and a limit block is installed on the outer wall of the limit rod.

[0014] Preferably, a temperature controller is installed on the outer wall of the left fixed frame on one side of the limiting frame, and the output end of the temperature controller is electrically connected to the input end of the temperature sensor and the electric heating tape.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the constant temperature heat tracing and anti-blocking structure not only realizes convenient constant temperature heat tracing for the microcrystalline wax melting and conveying pipeline, avoiding the solidification of the microcrystalline wax inside the pipeline due to excessively low temperature, thus improving the effect of constant temperature heat tracing and anti-blocking, but also facilitates the convenient disassembly of the constant temperature heat tracing and anti-blocking structure, thus improving the convenience of installation and disassembly of the constant temperature heat tracing and anti-blocking structure; (1) Install the left and right fixed brackets on the surface of the microcrystalline wax melting and conveying pipe that requires constant temperature heat tracing and anti-clogging. Manually rotate the two sets of handwheels. The handwheels drive the threaded rod to rotate, the threaded sleeve drives the threaded rod to move, the threaded rod drives the two sets of clamping arms to move, the clamping arms drive multiple sets of first springs to move, the multiple sets of first springs drive the insulation layer to move, the insulation layer drives multiple sets of electric heating tape to move, and the multiple sets of electric heating tape drive the heat-conducting layer to move. At the same time, under the support of the clamping arms on the multiple sets of first springs, the multiple sets of first springs elastically drive the two sets of insulation layers to move, the insulation layer elastically drives the multiple sets of electric heating tape to move, and the multiple sets of electric heating tape drive the heat-conducting layer to move elastically, so as to facilitate the two sets of heat-conducting layers to fit tightly against the surface of the pipe. When the multiple sets of electric heating tapes are energized, the electric heating tapes directly convert electrical energy into electrical energy. The heat generated by the electric heating tape is converted into heat energy and conducted to the inside of the pipe through the heat-conducting layer. This facilitates constant-temperature heating of the microcrystalline wax inside the pipe, preventing the microcrystalline wax from solidifying due to excessively low temperature and causing pipe blockage. When the temperature sensor detects that the temperature inside the pipe is too high, it sends a signal to the temperature controller. The temperature controller performs logical operations on the signal sent by the temperature sensor through its built-in processor, which allows the temperature controller to reduce the power supply time of the electric heating tape or reduce the power, avoiding energy waste and overheating of the medium. This constant-temperature heating and anti-blocking structure provides convenient constant-temperature heating for the microcrystalline wax melting and conveying pipe, preventing the microcrystalline wax inside the pipe from solidifying due to excessively low temperature and causing pipe blockage, thus improving the effect of constant-temperature heating and anti-blocking of the pipe. (2) Manually install the left and right fixed brackets onto the surface of the pipe. Manually push the right fixed bracket to facilitate its rotation around the pivot axis. The right fixed bracket moves the connecting seat, which in turn moves the limiting rod. The second spring causes the fixed block to move elastically. The sliding rod slides inside the support frame to provide sliding support for the fixed block, facilitating the limiting rod's positioning and fixing with the cooperation of the two sets of fixed blocks and the limiting block. This makes it easy to fix the left and right fixed brackets onto the surface of the pipe. When it is necessary to disassemble the left and right fixed brackets, manually pull... The pull rings on both sides are activated. When the manual pulling force exceeds the spring compression force, the pull rings drive the sliding rod to move. The support frame provides sliding support for the sliding rod, which in turn drives the fixed block to move. This allows the two sets of fixed blocks to no longer limit the limit block, making it easier to remove the limit rod from inside the limit frame and to conveniently disassemble the left and right fixed frames from the surface of the pipe. This enables the constant temperature heat tracing anti-clogging structure to be easily installed on the pipe surface and facilitates its disassembly, thus improving the convenience of installation and disassembly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-7 This utility model provides an embodiment of a constant temperature heat tracing and anti-clogging structure for a microcrystalline wax melting and conveying pipeline, including a left fixed frame 1 and a right fixed frame 2. The right fixed frame 2 is arranged outside the left fixed frame 1. Clamping arms 3 are symmetrically arranged between the left fixed frame 1 and the right fixed frame 2. Each clamping arm 3 is provided with an insulation layer 5. Multiple sets of first springs 4 with equal spacing are installed on the outer wall of the clamping arm 3 near the insulation layer 5. One end of the first spring 4 is connected to the insulation layer 5, and the other end of the first spring 4 is connected to the clamping arm 3. A heat-conducting layer 7 is provided outside the insulation layer 5. Multiple sets of electric heating tapes 6 with equal spacing are installed on the outer wall of the heat-conducting layer 7 near the insulation layer 5. The electric heating tapes 6 are connected to the insulation layer 5, and one of them... Temperature sensor 9 is installed on the outer wall of insulation layer 5. Threaded sleeves 12 are installed on the outer walls of left fixed frame 1 and right fixed frame 2. Threaded rods 11 are movably installed inside threaded sleeves 12 and extend to the outside of threaded sleeves 12. Threaded sleeves 12 and threaded rods 11 are threadedly connected. Threaded rods 11 are connected to clamping arms 3. Handwheels 10 are installed on the outer wall of threaded rods 11 on the side away from threaded sleeves 12. A left fixed seat 13 is installed at the bottom of left fixed frame 1. A right fixed seat 15 is installed at the bottom of right fixed frame 2 on the side of left fixed seat 13. A rotating shaft 14 is movably installed on the outer wall of left fixed seat 13 near right fixed seat 15. Left fixed seat 13 is movably connected to right fixed seat 15 via rotating shaft 14. The left fixing bracket 1 and the right fixing bracket 2 are manually installed on the surface of the microcrystalline wax melting and conveying pipe that requires constant temperature heat tracing and anti-clogging. Two sets of handwheels 10 are manually rotated, causing the threaded rod 11 to rotate. With the left and right fixing brackets 1 and 2 limiting the threaded sleeve 12, and with the threaded connection between the threaded rod 11 and the threaded sleeve 12, the threaded sleeve 12 moves the threaded rod 11. The threaded rod 11 moves the two sets of clamping arms 3, which in turn move multiple sets of first springs 4. These first springs 4 move the insulation layer 5, which in turn move multiple sets of electric heating tape 6. These electric heating tape 6 then move the heat-conducting layer 7. Simultaneously, supported by the clamping arms 3 and the multiple sets of first springs 4, the springs elastically move the two sets of insulation layers 5, which in turn move the multiple sets of electric heating tape 6. These electric heating tape 6 then move the heat-conducting layer 7, facilitating a tight fit between the two sets of heat-conducting layers 7 and the pipe surface. The temperature controller 8 controls the opening of multiple sets of electric heating tapes 6. When the multiple sets of electric heating tapes 6 are powered on, the electric heating tapes 6 directly convert electrical energy into heat energy. The heat generated by the electric heating tapes 6 is conducted to the inside of the pipe through the heat-conducting layer 7, so as to facilitate constant temperature heating of the microcrystalline wax inside the pipe and prevent the microcrystalline wax from solidifying due to low temperature, which would cause pipe blockage. When the temperature sensor 9 detects that the temperature inside the pipe is too high, the temperature sensor 9 sends a signal to the inside of the temperature controller 8. The temperature controller 8 performs logical operations on the signal sent by the temperature sensor 9 through the built-in processor, so as to facilitate the temperature controller 8 to reduce the power supply time of the electric heating tapes 6 or reduce the power, avoid energy waste and overheating of the medium. This achieves a constant temperature heating and anti-blocking structure for the microcrystalline wax melting and conveying pipe, which can conveniently provide constant temperature heating and prevent the microcrystalline wax inside the pipe from solidifying due to low temperature, which would cause pipe blockage. This improves the effect of constant temperature heating and anti-blocking of the pipe. A limiting seat 16 is installed at the top of the left fixed frame 1 on the side away from the left fixed seat 13. A limiting frame 18 is installed at the top of the limiting seat 16. A connecting seat 17 is installed at the top of the right fixed frame 2 on the side of the limiting seat 16. A limiting rod 19 is installed on the outer wall of the connecting seat 17. Support frames 20 are symmetrically installed on the outer wall of the limiting frame 18. Sliding rods 21 are slidably installed inside the support frames 20, and the sliding rods 21 extend into the interior of the limiting frame 18. Pull rings 22 are movably installed on the outer wall of the sliding rods 21. A fixing block 24 is installed at the end of the sliding rods 21 away from the pull ring 22. A second spring 23 is fitted on the surface of the sliding rods 21. One end of the second spring 23 is connected to the fixing block 24, and the other end of the second spring 23 is connected to the support frame 20. A limiting block 25 is installed on the outer wall of the limiting rod 19. A temperature controller 8 is installed on the outer wall of the left fixed frame 1 on the side of the limiting frame 18. The output end of the temperature controller 8 is electrically connected to the input end of the temperature sensor 9 and the electric heating tape 6. When the left fixing bracket 1 and the right fixing bracket 2 need to be installed on the pipe surface, the left fixing bracket 1 and the right fixing bracket 2 are manually fitted onto the pipe surface. The right fixing bracket 2 is manually pushed to facilitate its rotation around the rotating shaft 14. The left fixing seat 13 provides movable support for the rotating shaft 14, and the right fixing seat 15 supports the right fixing bracket 2. The right fixing bracket 2 drives the connecting seat 17 to move, and the connecting seat 17 drives the limiting rod 19 to move. The limiting rod 19 drives the limiting block 25 to move into the limiting bracket 18. Under the support of the second spring 23 by the support frame 20, the second spring 23 drives the fixing block 24 to move elastically. The sliding rod 21 slides inside the support frame 20 to provide sliding support for the fixing block 24, so that the two sets of fixing blocks 24 and limiting blocks 25 can cooperate to limit the limiting rod 19. The left and right fixed brackets 1 and 2 are fixed to the surface of the pipe. When the left and right fixed brackets 1 and 2 need to be disassembled, the pull rings 22 on both sides are pulled manually. When the manual pulling force exceeds the compression force of the spring, the pull rings 22 drive the sliding rod 21 to move. The support frame 20 provides sliding support for the sliding rod 21. The sliding rod 21 drives the fixed block 24 to move, so that the two sets of fixed blocks 24 no longer limit the limit block 25, so that the limit rod 19 can be taken out from the inside of the limit frame 18, and so that the left and right fixed brackets 1 and 2 can be easily disassembled from the surface of the pipe. This realizes the convenient installation of the constant temperature heat tracing anti-blocking structure on the surface of the pipe, facilitates the convenient disassembly of the constant temperature heat tracing anti-blocking structure, and improves the convenience of installation and disassembly of the constant temperature heat tracing anti-blocking structure.

[0020] In this embodiment, during use: the left fixing bracket 1 and the right fixing bracket 2 are installed on the surface of the microcrystalline wax melting and conveying pipe requiring constant temperature heating and anti-clogging. Two sets of handwheels 10 are manually rotated. The handwheels 10 drive the threaded rod 11 to rotate, the threaded sleeve 12 drives the threaded rod 11 to move, the threaded rod 11 drives the two sets of clamping arms 3 to move, the clamping arms 3 drive multiple sets of first springs 4 to move, the multiple sets of first springs 4 drive the insulation layer 5 to move, the insulation layer 5 drives multiple sets of electric heating tape 6 to move, and the multiple sets of electric heating tape 6 drive the heat-conducting layer 7 to move. Simultaneously, under the support of the clamping arms 3 and the multiple sets of first springs 4, the multiple sets of first springs 4 elastically drive the two sets of insulation layers 5 to move, and the insulation layer... 5. The elastic movement of multiple sets of electric heating tapes 6, which in turn cause the elastic movement of the heat-conducting layer 7, facilitates a tight fit between the two heat-conducting layers 7 and the pipe surface. When the multiple sets of electric heating tapes 6 are energized, they directly convert electrical energy into heat energy, which is then conducted to the interior of the pipe through the heat-conducting layer 7. This facilitates constant-temperature heating of the microcrystalline wax inside the pipe, preventing the microcrystalline wax from solidifying due to excessively low temperatures and causing pipe blockage. When the temperature sensor 9 detects that the temperature inside the pipe is too high, it sends a signal to the temperature controller 8. The temperature controller 8 then processes the temperature sensor data through its built-in processor. The signal sent by device 9 is used for logical operations to facilitate the temperature controller 8 in reducing the energizing time or power of the electric heating tape 6, avoiding energy waste and overheating of the medium. The left fixed bracket 1 and the right fixed bracket 2 are manually fitted onto the surface of the pipe. The right fixed bracket 2 is manually pushed to facilitate its rotation around the flip shaft 14. The right fixed bracket 2 drives the connecting seat 17 to move, and the connecting seat 17 drives the limiting rod 19 to move. The second spring 23 drives the fixed block 24 to move elastically. The sliding rod 21 slides inside the support frame 20 to provide sliding support for the fixed block 24, so that the two sets of fixed blocks 24 and the limiting block 25 can cooperate to limit the limiting rod 19. The left and right fixed brackets 1 and 2 are fixed to the surface of the pipe. When the left and right fixed brackets 1 and 2 need to be disassembled, the pull rings 22 on both sides are pulled manually. When the manual pulling force exceeds the compression force of the spring, the pull rings 22 drive the sliding rod 21 to move. The support frame 20 provides sliding support for the sliding rod 21. The sliding rod 21 drives the fixed block 24 to move, so that the two sets of fixed blocks 24 no longer limit the limit block 25, so that the limit rod 19 can be taken out from the inside of the limit frame 18, so that the left and right fixed brackets 1 and 2 can be easily disassembled from the surface of the pipe, thus completing the use of the constant temperature heat tracing anti-blocking structure.
