Description

Technical Field

[0001] The present invention relates to the field of pipeline ultrasonic descaling equipment, and in particular to an ultrasonic transducer descaling device and a use method thereof. Background Art

[0002] The mechanism of ultrasonic cleaning is to use the physical effects of cavitation, radiation pressure, and acoustic streaming when ultrasonic waves propagate in the cleaning fluid to mechanically remove dirt from the cleaning objects, thereby achieving the purpose of cleaning the objects. Specifically, it mainly includes: 1. Cohesion effect. When the ultrasonic pulse oscillates high elastic waves, the energy wave passes through the flowing medium of suspended particles. Due to the different sizes of particles, the vibration speeds are also different. The particles will collide and adhere to each other, increasing their volume and weight. This causes large particles to condense and disperse on the pipe wall, preventing the formation of scale. 2. Micro-vortex effect. When the ultrasonic transducer emits ultrasonic pulse oscillation elastic waves, when it acts on the medium of the heat exchange equipment, the impact of the transmitted pulse oscillation high energy wave accelerates the molecular motion per unit volume / area of ​​the medium, generates a dispersion force, forms high-speed micro-vortices, and breaks up scale. 3. Shear effect. When the ultrasonic pulse propagates on the pipe wall, the scale layer on the pipe wall oscillates synchronously with the pipe wall. Due to the different elastic coefficients of the pipe wall and the scale layer, different deformation and displacement are generated, forming shear force, causing fatigue, cracks, loosening, and subsequent breakage and shedding of the scale layer.

[0003] When the current ultrasonic transducer is used as a descaling device, since the waveguide as the final transmission component of the ultrasonic wave needs to be stably connected to the workpiece, it is usually welded to the surface of the workpiece, and the waveguide and the horn of the transducer are subsequently screwed together by threads. However, due to the high temperature of the waveguide during the welding process, in order to avoid damage to the horn, the horn and the waveguide need to be separated when welding the waveguide to the workpiece to be descaled. After the waveguide is fixed to the workpiece, the horn is driven by the rotating transducer housing to tighten and fix it to the waveguide, and the other end of the wire needs to be stably connected to the power supply host. In order to avoid overheating, The power supply wire of the acoustic transducer rotates with the transducer housing, causing entanglement or even twisting and breaking. Usually, the wire and the ultrasonic transducer are set to be pluggable, or the wire is directly connected to the top cover of the transducer housing, and the top cover is set to a detachable structure. The wire can be plugged in and out of the housing at the same time through the top cover. However, the high-frequency current used by the ultrasonic transducer has high requirements on the wiring stability of the wire. The existing plug-in connection power supply structure is prone to cause loose connection or even short circuit of the wire, and the installation and connection method of disassembling the top cover to arrange the ultrasonic transducer is cumbersome and inconvenient to use. Summary of the Invention

[0004] The purpose of the present invention is to provide an ultrasonic transducer descaling device and a method of using the same in order to solve the above-mentioned problems. By fixing a top support ring on the top of the transducer housing, the top support ring is used to support the guide assembly and the bottom conductive slip ring for rotation, so that the transducer housing and the amplitude transformer can be rotated without separating the wires and the top cover, thereby facilitating the tightening connection between the tool head and the waveguide, solving the problem of easily damaging the wires when the wires are wound during the rotation of the transducer housing, ensuring the structural stability of the power supply line, and improving the operational convenience of the rotation and unlocking action of the installation cylinder.

[0015] The method for using the ultrasonic transducer descaling device comprises the following steps:

[0016] a. When ultrasonically descaling a workpiece, first unscrew the waveguide from the tool head, weld and fix the tool head to the surface of the workpiece that requires ultrasonic descaling by surfacing welding, and then press the tool head at the end of the horn against the threaded hole opening at the end of the waveguide. At this time, press the pick with your fingers to drive the operating piece toward the gear shaft, thereby separating the outer teeth at the bottom end of the operating piece from the gear ring of the top support ring, so as to release the rotation locking state of the mounting cylinder. At this time, the guide assembly as a whole and the conductive slip ring can rotate relative to the top support ring and the transducer housing;

[0017] b. When the latching teeth are disengaged from the gear ring, rotate the transducer housing with the support of the guide assembly, and use the transducer housing to drive the horn and the tool head to rotate, so that the tool head at the end of the horn is threadedly fixed to the inner side of the waveguide end, completing the fixed installation of the ultrasonic transducer descaling device on the workpiece surface. Then, release the pick, and push the operating piece back to its original position through the compressed spring, so that the latching teeth on the outside of the operating piece are engaged and locked into the gear ring of the top support ring again, so as to lock the guide assembly as a whole into the inside of the top support ring, thereby preventing the rotor and stator brushes of the conductive slip ring from rotating relative to each other;

[0018] c. Power is supplied to the magnetostrictive component through a conductive slip ring, and the ferrite sheet is energized to generate magnetism to achieve up and down reciprocating telescopic vibration. The amplitude of the ultrasonic vibration generated by the ferrite sheet is adjusted through the amplitude rod below, and the ultrasonic vibration is transmitted to the workpiece along the tool head and waveguide below by the amplitude rod, thereby removing dirt from the workpiece surface through ultrasonic vibration.

[0019] The beneficial effects are as follows: the present invention fixes a top support ring on the top of the transducer housing, and uses the top support ring to support the guide assembly and the conductive slip ring on the bottom side for rotation, so that the transducer housing and the horn can be rotated without separating the wires, which facilitates the tightening connection between the tool head and the waveguide, is simple to operate, solves the problem of easily damaging the wires when the wires are entangled during the rotation of the transducer housing, and ensures the structural stability of the power supply line;

[0020] In addition, an operating piece is provided inside the installation tube, which can be locked to the gear ring on the inner side of the top support ring.

A circular shock-absorbing washer 10 is provided between the top support ring 8 and the transducer housing 1. Specifically, a shock-absorbing washer 10 made of rubber is provided at the joint between the top support ring 8 and the transducer housing 1 to prevent the high-frequency ultrasonic vibration of the horn 3 inside the transducer housing 1 from causing loosening of the mounting structure inside the top support ring 8.

[0038] The internal thread of the fixed ear 102 is matched with a hand screw 103 that presses down the movable ear 801 and the top support ring 8. The outer side of the shock-absorbing washer 10 is integrally formed with a positioning ear 10a that accommodates the hand screw 103 to vertically penetrate.

The conductive slip ring 7 includes A support bracket 701 is fixed to the bottom of the mounting tube 901. A rotor 702 is fixed to the middle of the support bracket 701. Two sets of conductive rings are arranged vertically and side by side on the outside of the rotor 702. Two sets of external wires 703 electrically connected to the conductive rings are arranged inside the rotor 702. A wire tube 905 is longitudinally connected to the front side of the top of the mounting tube 901 to guide the external wires 703 to extend outward. The external power supply host is connected through the external wires 703 to ensure that the power supply wires of the ultrasonic transducer descaling device are integrated with the mounting tube 901.

[0039] The rotor 702 is provided with a stator brush 704 fixed to the inside of the transducer housing 1. The stator brush 704 is electrically connected to the conductive ring on the outside of the rotor 702 through the brush. Two internal wires 705 are provided on the outside of the stator brush 704, which are respectively connected to the two sets of terminal blocks 604 on the outside of the pressure seat 602. Power is supplied to the ferrite sheet 601 through the two internal wires 705, causing it to generate magnetism and vibrate up and down, thereby generating ultrasonic waves for descaling.

[0040] A circular ring gear 802 is provided on the inner side of the top support ring 8, two sets of side grooves 901a are horizontally penetrated on both sides of the mounting cylinder 901, and a cover plate 902 is fixed to the top opening of the mounting cylinder 901. Two sets of guide grooves 902a are provided on the outer side of the cover plate 902 corresponding to the side grooves 901a. An operating piece 903 is provided on the inner side of the two sets of side grooves 901a. The bottom side of the operating piece 903 extends downward to the inner side of the top support ring 8, and the outer side of the bottom end of the operating piece 903 is fixed with an engaging locking ring gear 802. The latch teeth 904 lock the gear ring 802 through the latch teeth 904 to lock the rotation state of the guide assembly 9 and the rotor 702.

The bottom end of the gear shaft 906 is fixed with a synchronous gear 907, and the opposite sides of the two sets of support rods 908 are provided with racks 908a that mesh with the synchronous gear 907. The synchronous gear 907 is used to transmit the racks 908a on the front and rear sets of support rods 908 to ensure that when the outer operating piece 903 is pushed to drive the support rod 908 to move horizontally, the synchronous gear 907 can drive the support rod 908 and the operating piece 903 on the other side to move in the opposite direction, thereby realizing the synchronous engagement and locking and synchronous separation and unlocking of the ring gear 802 by the card teeth 904 on both sides, which is more convenient and stable to use.

[0041] The method for using the ultrasonic transducer descaling device includes the following steps:

[0042] a. When ultrasonically descaling a workpiece, first unscrew the waveguide 5 from the tool head 4, weld the tool head 4 to the surface of the workpiece to be ultrasonically descaled by surfacing welding, and then press the tool head 4 at the end of the horn 3 against the threaded hole opening at the end of the waveguide 5. At this time, press the pick 903a with your finger to drive the operating piece 903 to move toward the gear shaft 906, thereby separating the outer locking tooth 904 at the bottom end of the operating piece 903 from the gear ring 802 of the top support ring 8, so as to release the rotation locking state of the mounting cylinder 901. At this time, the guide assembly 9 as a whole and the conductive slip ring 7 can rotate relative to the top support ring 8 and the transducer housing 1;

[0043] b. When the latching teeth 904 are disengaged from the gear ring 802, the transducer housing 1 is rotated with the support of the guide assembly 9, and the horn 3 and the tool head 4 are driven to rotate by the transducer housing 1, so that the tool head 4 at the end of the horn 3 is threadedly fixed to the inner side of the end of the waveguide 5, completing the fixed installation of the ultrasonic transducer descaling device on the surface of the workpiece. Thereafter, the paddle 903a is released, and the operating piece 903 is pushed back by the compressed spring 909, and the latching teeth 904 on the outer side of the operating piece 903 are engaged and locked into the gear ring 802 of the top support ring 8 again, so as to lock the guide assembly 9 as a whole into the interior of the top support ring 8, thereby preventing the rotor 702 and the stator brush 704 of the conductive slip ring 7 from rotating relative to each other.

[0044] c. Power is supplied to the magnetostrictive assembly 6 through the conductive slip ring 7. The ferrite sheet 601 is energized to generate magnetism to achieve up and down reciprocating telescopic vibration. The amplitude of the ultrasonic vibration generated by the ferrite sheet 601 is adjusted by the lower horn 3. The ultrasonic vibration is transmitted to the workpiece along the lower tool head 4 and waveguide 5 by the horn 3, thereby removing dirt from the workpiece surface through ultrasonic vibration.

[0045] By fixing a top support ring 8 on the top of the transducer housing 1 and using the top support ring 8 to support the rotation of the guide assembly 9 and the conductive slip ring 7 on the bottom side, the transducer housing 1 and the horn 3 can be rotated without separating the wires and the top cover, making it easy to tighten the tool head 4 and the waveguide 5. The operation is simple and solves the problem of easily damaging the wires due to winding during the rotation of the transducer housing 1, thereby ensuring the structural stability of the power supply line.

[0046] In addition, an operating piece 903 is provided inside the mounting tube 901, which can be locked to the inner gear ring 802 of the top support ring 8. The latching teeth 904 on the outer side of the operating piece 903 engage the gear ring 802, thereby rotating and locking the mounting tube 901 inside the gear ring 802. This prevents the stator brush 704 and the rotor 702 of the conductive slip ring 7 from rotating relative to each other during the descaling operation of the equipment, and prevents the external wire 703 and the wire tube 905 from rotating and affecting the descaling process.

[0047] A gear shaft 906 is set inside the installation cylinder 901 to support the rotation of the synchronous gear 907, and the synchronous gear 907 is used to keep the front and rear sets of support rods 908 sliding in the opposite directions synchronously, so that when pressing the paddle 903a on one side to drive the operating piece 903 to move horizontally, it can also drive the operating piece 903 on the other side to move, ensuring that the locking teeth 904 on both sides can synchronously disengage or engage with the outer gear ring 802, thereby improving the locking stability of the installation cylinder 901 in the middle of the top support ring 8, and improving the operational convenience of the rotation and unlocking action of the installation cylinder 901.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention.
