Description

Technical Field

[0001] The present application relates to the field of descaling technology, and in particular to a variable frequency electromagnetic descaling device. Background Art

[0002] The variable frequency electromagnetic scale removal device is a device used to remove scale in pipes or equipment. It uses the principle of electromagnetic field to make the scale in the pipe lose its adhesion through the variable frequency electromagnetic field, and then flushes or removes it from the pipe through water flow or other media, thereby achieving a cleaning effect.

[0003] At present, variable frequency electromagnetic descaling devices usually include two sets of electromagnetic coils, power supply, control system, and frequency converter. The power supply provides electrical energy, the control system is used to adjust the electromagnetic field parameters, and the electromagnetic coil is a device that converts electrical energy into an electromagnetic field. It is installed on the pipeline or equipment to remove the scale layer. When installing the electromagnetic coil, the staff needs to wrap the cable side by side along the pipeline for multiple turns and fix it to form an electromagnetic coil. Two sets of electromagnetic coils need to be set, and the two sets need to be separated by a certain distance.

[0004] However, the temperature of the liquid in the pipeline will change with production needs and the temperature will be transferred to the cable through the side wall of the pipeline. At the same time, the cable in the electromagnetic coil will also expand and contract with the change of seasonal temperature. When the temperature of the cable is high, the cable wrapped around the side wall of the pipeline will become loose due to the thermal expansion, resulting in a large gap between the cable and the side wall of the pipeline, making it difficult to fit tightly, resulting in uneven intensity of the electromagnetic field or partial escape of the electromagnetic field, thereby weakening the effect of removing the scale layer and increasing energy consumption and cost. When the cable is affected by cold contraction, the cable wrapped around the side wall of the pipeline will be too tight, resulting in excessive local tension and damage to the cable, which will not only cause safety hazards, but also affect the normal use of the electromagnetic coil. Summary of the invention

[0005] In order to make the cable wrapped around the side wall of the pipeline produce adaptive changes after being affected by temperature, to keep the strength of the electromagnetic field generated by the electromagnetic coil uniform, to enhance the effect of removing scale layers, to reduce energy consumption and costs, and to improve the stability of the operation of the descaling device, the present application provides a variable frequency electromagnetic resistance descaling device.

[0006] The variable frequency electromagnetic descaling device provided in this application adopts the following technical solution: A variable frequency electromagnetic descaling device, comprising: Descaling device body; The electromagnetic coils are arranged in two groups and are arranged at intervals. The electromagnetic coils include a first cable used to be wound side by side to the outside of the pipeline, and the first cable is connected to the descaling device body; A fixing assembly is arranged on the outer wall of the pipeline, and one is arranged on both sides of each set of electromagnetic coils, and is used to fix the position of the electromagnetic coils; A support seat is arranged on one side of the electromagnetic coil and connected to the fixing assembly; The telescopic tensioning mechanism is arranged between the first cable and the support seat, and is used to connect the first cable and automatically apply tension to the first cable to perform tensioning processing, so that the first cable is closely attached to the side wall of the pipeline.

[0007] By adopting the above technical scheme, when descaling is performed by using a variable frequency electromagnetic scale resistance descaling device, firstly, a first cable is wound around the side wall of the pipeline in parallel to form an electromagnetic coil, and two groups of electromagnetic coils are installed on the outer wall of the pipeline at intervals, and then fixing components are installed at both ends of each group of electromagnetic coils to fix the position of the electromagnetic coils, and then the first cable is connected to the telescopic tensioning mechanism, so that tension is automatically applied to the first cable for tensioning, so that the first cable is close to the side wall of the pipeline; when the temperature of the liquid in the pipeline changes with production needs, causing the cable temperature to rise, or the cable in the electromagnetic coil undergoes thermal expansion effect due to seasonal temperature changes, and the cable wound around the side wall of the pipeline becomes loose, the telescopic tensioning mechanism can automatically and continuously apply tensioning tension to the first cable to keep the first cable tight. A cable is attached to the side wall of the pipeline; when the temperature of the liquid in the pipeline changes with production needs, causing the cable temperature to drop, or the cable in the electromagnetic coil shrinks due to seasonal temperature changes, the cable wrapped around the side wall of the pipeline becomes tight, and the telescopic tensioning mechanism can compensate the first cable, thereby reducing the tension between the first cable, so that the tight cable is not easily damaged by excessive local tension; wherein the telescopic tensioning mechanism enables the cable wrapped around the side wall of the pipeline to automatically produce adaptive changes after being affected by temperature, so that the first cable is always attached to the outer wall of the pipeline with appropriate tension, so that the strength of the electromagnetic field generated by the electromagnetic coil remains uniform, thereby enhancing the effect of removing the scale layer, while reducing energy consumption and cost, and improving the stability of the descaling device.

[0008] Optionally, the telescopic tensioning mechanism comprises: A rotating shaft, rotatably connected to the support seat; A torque spring is sleeved on the outside of the rotating shaft, a cavity is opened in the support seat, and the torque spring is located in the cavity; An energy charging component is disposed between the rotating shaft and the supporting seat, and is used to drive the rotating shaft to rotate so as to apply a torsional force to the torque spring for charging; A connecting seat, detachably connected to the end of the supporting seat; The winding roller is rotatably connected to the connecting seat and is detachably connected to the rotating shaft; The second electric cable is wound around the winding roller and partially fixedly connected to the winding roller. One end of the second electric cable is connected to the first electric cable, and the other end is connected to the descaling device body.

[0009] By adopting the above technical solution, the telescopic tensioning mechanism continuously and automatically applies tensioning tension to the first cable to keep the first cable close to the side wall of the pipeline. First, the staff drives the rotating shaft to rotate through the charging component. The rotating shaft is connected to the torque spring, and a torsional force is applied to charge the torque spring. Then, the second cable is connected to the first cable and tightened. Then, the connecting seat is connected to the end of the supporting seat, and the winding roller is connected to the rotating shaft. The installation of the telescopic tensioning mechanism can be completed. During the operation of the telescopic tensioning mechanism, the telescopic tensioning mechanism can tension the first cable and the second cable. A certain tensioning force is continuously and automatically applied to keep the first cable close to the side wall of the pipeline; through the charging and releasing of the torque spring, the telescopic tensioning mechanism can automatically adjust the tension of the first cable to keep it in an appropriate tensioned state at all times, thereby ensuring that the electromagnetic coil can effectively close to the side wall of the pipeline, and the torque spring is a consumable. When the torque spring is used continuously for a period of time and is greatly deformed or damaged, the staff only needs to remove the connecting seat, replace it with a new torque spring, and charge it again through the charging component, and it can be used normally again, thereby increasing the service life of the telescopic tensioning mechanism.

[0010] Optionally, the charging component includes: A plug-in rod is arranged at one end of the torque spring; A fixing rod, arranged at an end of the torque spring away from the plug-in rod; A plug-in splint is arranged on the rotating shaft, and the plug-in rod is plugged into the plug-in splint; The anti-dropping splint is arranged on the supporting seat, and the fixing rod is inserted into the anti-dropping splint.

[0011] By adopting the above technical solution, when installing the torque spring, first, the torque spring is sleeved and plugged onto the rotating shaft and pushed into the cavity, then the plug-in rod at one end of the torque spring is plugged into the plug-in splint, and the fixing rod at the other end of the torque spring is clamped into the anti-dropping splint, thereby achieving the installation and fixation of the torque spring; when charging the rotating shaft through the charging assembly, it is only necessary to rotate the rotating shaft, and the rotating shaft applies a torsional force to the rotating shaft through the plug-in rod and the fixing rod, thereby charging the torque spring, wherein the staff can quickly complete the torque charging process through the charging assembly, and at the same time, the installation and maintenance of the torque spring are convenient.

[0012] Optionally, the energy charging assembly further includes a locking component disposed between the rotating shaft and the supporting seat for locking the position of the rotating shaft after rotation; The locking component comprises: A ratchet wheel, fixedly sleeved on the rotating shaft; A ratchet pawl is rotatably disposed on the support seat and meshes with the ratchet wheel; The torsion spring is arranged between the pawl and the support seat, and always gives the pawl a force to approach the ratchet wheel.

[0013] By adopting the above technical solution, when the rotating shaft rotates to the position that needs to be locked, the pawl will engage the ratchet, and due to the action of the torsion spring, the pawl will be subjected to a certain force so that it remains in an engaged state, thereby locking the position of the rotating shaft; wherein the engagement of the ratchet and the pawl and the force of the torsion spring can ensure that the rotating shaft remains stable in the position that needs to be locked, so that after the staff charges the rotating shaft, during the connection process of the rotating shaft and the winding roller, there is no need to hold the rotating shaft and continuously apply a torsional force, so that the torque spring can be kept from loosening, thereby improving the convenience of the staff in installing the torque spring.

[0014] Optionally, the energy charging assembly further includes an unlocking component disposed between the pawl and the support seat for continuously releasing the locking state of the locking component on the rotating shaft; The unlocking component comprises: A clamping block is arranged on a side of the pawl away from the ratchet wheel; A locking block, slidably connected to the support seat; An unlocking spring is arranged between the locking block and the supporting seat and always applies a thrust to the locking block; Wherein, a card slot is provided on the card block, and one end of the locking block can be inserted into the card slot.

[0015] By adopting the above technical solution, when it is necessary to release the locking state of the rotating shaft, the staff rotates the pawl to the side away from the ratchet, and the pawl drives the card block to move to the side close to the locking block. Then the locking block cooperates with the unlocking spring to insert the locking block into the card slot, so that the pawl can be kept separated from the ratchet for a long time, thereby achieving the unlocking of the rotating shaft.

[0016] Optionally, the charging component further includes: The torque sensor is arranged on the rotating shaft, and is used to detect the torsional force of the torque spring and send out a torque detection signal; A display screen, connected to the torque sensor, for displaying the torsional force of the torque spring; A signal light, arranged on a supporting base; The controller is connected to the torque sensor and the signal light, and is used to receive the torque detection signal to obtain the torsional force of the torque spring. When the torsional force of the torque spring is less than the preset torsional force, the controller outputs a control signal to the signal light to turn on the signal light.

[0017] By adopting the above technical solution, the torque sensor can detect the torsional force of the torque spring in real time and transmit the data to the display screen for display, so that the staff can intuitively observe the torque size of the torque spring. At the same time, the controller makes a judgment based on the data of the torque detection signal. If the torsional force of the torque spring is lower than the preset torsional force, the controller will send a control signal to light up the signal light, so as to promptly remind the staff to make timely adjustments, thereby ensuring the stability and reliability of the charging process.

[0018] Optionally, a hook is fixedly provided on the plug-in rod, and the hook is buckled to one side of the plug-in splint. An anti-slip plate is fixedly provided on one side of the connecting seat close to the supporting seat, and the anti-slip plate is tightly fitted with the outer wall of the fixing rod.

[0019] By adopting the above technical solution, the hook is buckled to one side of the plug-in splint, so that after the plug-in rod is subjected to torsional tension, the plug-in rod and the plug-in splint can be firmly connected and not easily separated; when the connecting seat is connected to the supporting seat, the anti-slip pressure plate on the connecting seat will exert a certain extrusion pressure on the outer wall of the fixed rod, further fixing the fixed rod, so that after the fixed rod is subjected to torsional tension, the fixed rod and the anti-slip splint are not easily separated.

[0020] Optionally, the first cable is detachably connected to the second cable.

[0021] By adopting the above technical solution, the first cable and the second cable are detachably connected. On the one hand, it is convenient for the staff to separate the two cables when necessary for maintenance, replacement or repair; on the other hand, the detachable connection can also simplify the installation and wiring process. When assembling or installing the descaling device, the staff can first separate the first cable and the second cable, and then connect the first cable and the second cable after the first cable is wound, making the installation process more convenient and flexible, saving installation time and effort.

[0022] Optionally, a support seat and a telescopic tensioning mechanism are provided on both sides of the length direction of each group of electromagnetic coils, and the two support seats are respectively connected to two fixing components.

[0023] By adopting the above technical solution, the telescopic tensioning mechanisms respectively arranged on both sides of the electromagnetic coil can make the two ends of the first cable in the electromagnetic coil evenly stressed, so that the first cable is not easily locally unevenly stressed and locally loose, thereby making the first cable close to the side wall of the pipeline.

[0024] Optionally, the fixing component includes: Pipe clamp, which is sleeved on the outside of the pipe; The telescopic rod is arranged between the pipe clamp and the supporting seat.

[0025] By adopting the above technical solution, the length of the telescopic rod can be changed, so that the staff can adjust the position of the support seat according to the thickness of the first cable in the electromagnetic coil and in combination with the telescopic rod, so that the support seat is not easy to interfere with the first cable, thereby facilitating the installation of the electromagnetic coil; on the other hand, it is convenient to connect the second cable with the first cable.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: When the temperature of the liquid in the pipeline changes with production needs, causing the temperature of the cable to rise, or the cable in the electromagnetic coil undergoes thermal expansion effect with seasonal temperature changes, and the cable line wound on the side wall of the pipeline becomes loose, the telescopic tensioning mechanism can automatically and continuously apply tensioning tension to the first cable line to keep the first cable line close to the side wall of the pipeline; when the temperature of the liquid in the pipeline changes with production needs, causing the temperature of the cable to drop, or the cable in the electromagnetic coil undergoes cold shrinkage effect with seasonal temperature changes, and the cable line wound on the side wall of the pipeline becomes tight, the telescopic tensioning mechanism can compensate for the first cable line, thereby reducing the tension between the first cable lines, so that the tight cable line is not easily damaged by excessive tension locally; wherein the telescopic tensioning mechanism enables the cable line wound on the side wall of the pipeline to automatically undergo adaptive changes after being affected by temperature, so that the first cable line is always close to the outer wall of the pipeline with appropriate tension, so that the strength of the electromagnetic field generated by the electromagnetic coil remains uniform, the effect of removing the scale layer is enhanced, while reducing energy consumption and cost, and improving the stability of the operation of the descaling device; Through the charging and releasing of the torque spring in the telescopic tensioning mechanism, the telescopic tensioning mechanism can automatically adjust the tension of the first cable to keep it in an appropriate tensioning state at all times, thereby ensuring that the electromagnetic coil can effectively approach the side wall of the pipeline.

[0029] The following is combined with Figure 1-Figure 6 This application is described in further detail.

[0030] The embodiment of the present application discloses a variable frequency electromagnetic descaling device. Figure 1 and Figure 2 The variable frequency electromagnetic resistance descaling device comprises a descaling device body 1, two groups of electromagnetic coils 3 for being sleeved on the outer wall of the pipe 2, wherein the two groups of electromagnetic coils 3 are arranged at intervals, and the electromagnetic coils 3 comprise a first cable 31 for being wound side by side to the outside of the pipe 2, and the first cable 31 is connected to the descaling device body 1. A fixing component 4 is arranged on the outer wall of the pipe 2, and one is arranged on both sides of each group of electromagnetic coils 3, and the fixing component 4 is used to fix the position of the electromagnetic coil 3. A support seat 5 is arranged on both sides of the length direction of each group of electromagnetic coils 3, and the two support seats 5 are respectively connected to the two fixing components 4. A telescopic tensioning mechanism 6 is arranged between the first cable 31 and the support seat 5, and the telescopic tensioning mechanism 6 is used to connect the first cable 31, and at the same time, automatically apply tension to the first cable 31 for tensioning, so that the first cable 31 is close to the side wall of the pipe 2.

The second cable 67 is wound around the outside of the winding roller 65 and is partially fixedly connected to the winding roller 65. One end of the second cable 67 is detachably connected to the first cable 31 through a quick connector 68, and the other end is detachably connected to the descaling device body 1 through a quick connector 68.

[0036] By using the telescopic tensioning mechanism 6 to continuously and automatically apply a tensioning force to the first cable 31 to keep the first cable 31 close to the side wall of the pipeline 2, the staff first drives the rotating shaft 61 to rotate through the charging component 63, and the rotating shaft 61 is connected to the torque spring 62, and a torsional force is applied to charge the torque spring 62, and then the second cable 67 is connected to the first cable 31 and tightened, and then the connecting seat 64 is connected to the end of the support seat 5, and the winding roller 65 is connected to the rotating shaft 61, and the installation of the telescopic tensioning mechanism 6 is completed.

[0037] In some embodiments, reference Figure 5 and Figure 6 The charging assembly 63 includes a plug-in rod 631 fixed to one end of the torque spring 62, and a fixed rod 632 is also fixed to the end of the torque spring 62 away from the plug-in rod 631. A plug-in clamp 633 is fixed to the rotating shaft 61, and a slot is provided on the plug-in clamp 633. The plug-in clamp 633 is plugged into the slot on the plug-in clamp 633. An anti-slip clamp 634 is fixed to the support seat 5, and an anti-slip groove 6341 is provided on the anti-slip clamp 634. The fixed rod 632 is plugged into the anti-slip groove 6341 on the anti-slip clamp 634. A hook 635 is fixed to the plug-in rod 631, and the hook 635 is buckled to one side of the plug-in clamp 633; ​​an anti-slip pressure plate 636 is fixed to the side of the connecting seat 64 close to the support seat 5, and the anti-slip pressure plate 636 is tightly fitted with the outer wall of the fixed rod 632. The hook 635 is buckled into one side of the plug-in splint 633, so that after the plug-in rod 631 is subjected to a torsional pulling force, the plug-in rod 631 and the plug-in splint 633 are firmly connected and are not easily separated; when the connecting seat 64 is connected to the supporting seat 5, the anti-slip pressure plate 636 on the connecting seat 64 will exert a certain squeezing force on the outer wall of the fixing rod 632, further fixing the fixing rod 632, so that after the fixing rod 632 is subjected to a torsional pulling force, the fixing rod 632 and the anti-slip splint 634 are not easily separated.

[0038] When installing the torque spring 62, first put the torque spring 62 on the rotating shaft 61 and push it into the cavity, then plug the plug rod 631 at one end of the torque spring 62 into the plug clamp 633, and make the hook 635 buckle to one side of the plug clamp 633, and then snap the fixing rod 632 at the other end of the torque spring 62 into the anti-drop clamp 634, so as to install and fix the torque spring 62. When charging the rotating shaft 61 through the charging assembly 63, it is only necessary to rotate the rotating shaft 61, and the rotating shaft 61 applies a torsional force to the rotating shaft 61 through the plug rod 631 and the fixing rod 632, so as to charge the torque spring 62.

A card slot 6385 is disposed on the support seat 5, and the card block 6381 can be plugged into the card slot 6385.

[0042] When it is necessary to release the locking state of the rotating shaft 61, the staff rotates the pawl 6372 to the side away from the ratchet 6371, and the pawl 6372 drives the card block 6381 to move to the side close to the locking block 6383, and then the locking block 6383 cooperates with the unlocking spring 6384 to insert the locking block 6383 into the card slot 6385, so that the pawl 6372 can be kept separated from the ratchet 6371 for a long time, thereby achieving the unlocking of the rotating shaft 61; when the fixation of the pawl 6372 is released by the unlocking component 638, the staff moves the locking block 6383 to the side away from the card slot 6385 to separate the locking block 6383 from the card slot 6385.

[0043] In some embodiments, reference Figure 5 and Figure 6 The charging assembly 63 also includes a torque sensor disposed on the rotating shaft 61, a display screen 639 and a signal light 6310 disposed on the support seat 5, and a controller; wherein the torque sensor is used to detect the torsional force of the torque spring 62 and send a torque detection signal. The display screen 639 is connected to the torque sensor and is used to display the torsional force of the torque spring 62. The controller is connected to the torque sensor and the signal light 6310 and is used to receive the torque detection signal to know the torsional force of the torque spring 62. When the torsional force of the torque spring 62 is less than the preset torsional force, a control signal is output to the signal light 6310 to light up the signal light 6310.

[0044] The torque sensor can detect the torsional force of the torque spring 62 in real time and transmit the data to the display screen 639 for display, so that the staff can intuitively observe the torque size of the torque spring 62. At the same time, the controller makes a judgment based on the data of the torque detection signal. If the torsional force of the torque spring 62 is lower than the preset torsional force, the controller will send a control signal to light up the signal light 6310, so as to promptly remind the staff to make timely adjustments.

[0045] The implementation principle of a variable frequency electromagnetic scale removal device in an embodiment of the present application is as follows: when descaling is performed by the variable frequency electromagnetic scale removal device, firstly, a first cable 31 is wound around the side wall of the outer side of the pipe 2 to form an electromagnetic coil 3, and two groups of electromagnetic coils 3 are installed at intervals on the outer wall of the pipe 2, and then fixing components 4 are installed at both ends of each group of electromagnetic coils 3 to fix the position of the electromagnetic coils 3, and then the first cable 31 is connected to the telescopic tensioning mechanism 6, so as to automatically apply tension to the first cable 31 for tensioning treatment, so that the first cable 31 is close to the side wall of the pipe 2; when the temperature of the liquid in the pipe 2 changes with production needs, causing the cable temperature to rise, or the cable in the electromagnetic coil 3 undergoes thermal expansion effect due to changes in seasonal temperature, after the cable wound around the side wall of the pipe 2 becomes loose, the telescopic tensioning mechanism 6 can continuously and automatically apply tension to the first cable 31 The tensioning force is tightened to keep the first cable 31 close to the side wall of the pipeline 2; when the temperature of the liquid in the pipeline 2 changes with production needs, causing the cable temperature to drop, or the cable in the electromagnetic coil 3 shrinks due to seasonal temperature changes, and the cable wrapped around the side wall of the pipeline 2 becomes tight, the telescopic tensioning mechanism 6 can compensate for the first cable 31, thereby reducing the tension between the first cable 31, so that the tight first cable 31 is not easily damaged by excessive tension locally; wherein the telescopic tensioning mechanism 6 enables the cable wrapped around the side wall of the pipeline 2 to automatically produce adaptive changes after being affected by temperature, so that the first cable 31 is always close to the outer wall of the pipeline 2 with appropriate tension, so that the strength of the electromagnetic field generated by the electromagnetic coil 3 remains uniform, thereby enhancing the effect of removing the scale layer, while reducing energy consumption and cost, and improving the stability of the descaling device operation.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
