Description

Technical Field

[0001] This invention belongs to the field of permanent magnet circuit design and special working condition magnetic field technology, specifically a uniform field magnetic component device and assembly method adapted to high temperature and high pressure reactor. Background Technology

[0002] High-temperature and high-pressure autoclaves are core equipment for testing the corrosion performance of metallic and non-metallic materials. They are widely used in the corrosion detection of special steels in fields such as nuclear power and chemical industry. In scenarios such as aging assessment of nuclear power materials and long-term failure analysis of steel used in chemical equipment, a stable and uniform magnetic field needs to be applied in a designated test area within the enclosed space of the autoclave to simulate the magnetic field environment during the material's service life and accurately observe the influence of the magnetic field on the corrosion rate and intergranular corrosion tendency.

[0003] Currently, the field shimming magnetic component device adapted to high temperature and high pressure reactors has been gradually applied to testing scenarios. However, when the existing field shimming magnetic component device is working in a high temperature and high pressure reactor, the surface temperature of the reactor body is high and the distance between the magnetic block and the high temperature and high pressure reactor is small. Heat is easily transferred to the magnetic component through heat conduction. Long-term high temperature will accelerate the demagnetization of the magnetic block, resulting in field strength attenuation and affecting test stability. At the same time, dust in the environment is easy to adhere to the surface of the magnetic component, affecting the heat dissipation effect. Manual cleaning is not only cumbersome, but also prone to safety hazards due to strong magnetic adsorption. Summary of the Invention

[0010] In the above technical solution, preferably, a guide rod is fixedly connected inside the dust collection sleeve, the brush plate is fitted on the guide rod, a second guide rod is fixedly connected inside the dust collection sleeve, and the square sleeve is fitted on the second guide rod.

[0011] In the above technical solution, preferably, a rotating cleaning component is provided on one side of the sleeve plate.

[0013] An assembly method for a field-uniform magnetic component device adapted to a high-temperature and high-pressure reactor, comprising the aforementioned field-uniform magnetic component device adapted to a high-temperature and high-pressure reactor, further comprising the following steps: S1: Clean all parts with anhydrous ethanol, embed 16 magnet blocks into the outer cylinder according to the Halbach magnetization direction, inject high-temperature resistant epoxy resin, fix with mold clamping fixture, cure at 80℃ for 2 hours, then cure at 120℃ for 1 hour, clean up excess resin, then fix two retaining rings inside the outer cylinder, and fix two rotating rings to both sides of the outer cylinder respectively to complete the pre-assembly of the magnetic assembly; then install the rotating rings on the outside of the high-temperature reactor, and fix the drive device on the high-temperature reactor to ensure that the coaxiality of the outer cylinder and the high-temperature reactor meets the standard; S2: Assemble the fixed sleeve inside the rotating ring through the bearing, and fix the rotating ring on the high temperature reactor. Install the fan inside the air guide tube. Finally, install the timer lifting device at the bottom of the air guide tube and connect the timer lifting device to the fan. S3: Install the vacuum cover on the timer lifting device, install the driven reciprocating component on the vacuum cover and connect it to the brush plate, check the reliability of the connection and movement of each component, and complete the final assembly.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a fan to generate airflow to dissipate heat from the magnet block. A timed lifting device can periodically raise and lower the fan and dust collection sleeve. Together with a pair of rotating outer cylinders with a brush plate, it performs cleaning and dust collection. Combined with a self-cleaning dustproof component, it achieves double dustproof cleaning, avoiding long-term high-temperature demagnetization of the magnet block, while preventing the accumulation of impurities from affecting the heat dissipation effect. It eliminates the safety hazards and tedious operation of manual cleaning, extends the service life of the device, and ensures the stability of the magnetic field and the accuracy of corrosion testing.

[0015] Furthermore, although the dust cover can drive the brush plate to contact the outer cylinder for cleaning, the brush plate does not reciprocate, resulting in incomplete cleaning of impurities attached to the outer cylinder and poor cleaning effect. However, by designing a driven reciprocating component with a reducer, rubber wheel, and eccentric wheel, the rubber wheel contacts the outer cylinder after the dust cover moves down. The rotation of the outer cylinder drives the rubber wheel to rotate synchronously, which in turn drives the eccentric wheel to rotate. As the eccentric wheel rotates, it pushes the dust cover and brush plate to reciprocate within the dust cover, enhancing the cleaning force of the brush plate. This effectively removes firmly attached impurities from the surface of the outer cylinder, significantly improving the cleaning effect and further ensuring stable heat dissipation of the magnet block.

[0016] Furthermore, while the second brush plate can clean the filter, it only moves horizontally with the vacuum sleeve, resulting in a limited cleaning method and incomplete removal of impurities from the filter, easily leading to localized dust accumulation and blockage. However, through the structural design of the trapezoidal sleeve, rotating rod, and arc-shaped plate in the rotating cleaning component, the air discharged from the exhaust hose enters the trapezoidal sleeve, driving the arc-shaped plate to rotate. This, in turn, causes the rotating rod and perforated disc to rotate within the sleeve, enabling the second brush plate to perform a rotating cleaning action. This allows for comprehensive cleaning of the attached impurities on the filter, while also facilitating the perforated disc to vacuum different areas of the filter, further improving self-cleaning and heat dissipation effects.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: As Figures 1 to 4 As shown, this invention provides a uniform magnetic component device adapted to a high-temperature and high-pressure autoclave, including an outer cylinder 1, a magnet block 2 fixedly connected inside the outer cylinder 1, two symmetrically arranged retaining rings 3 fixedly connected inside the outer cylinder 1, a high-temperature autoclave 4 disposed inside the outer cylinder 1, a driving device 5 disposed on the high-temperature autoclave 4, and rotating rings 6 fixedly connected to both sides of the outer cylinder 1, and further including: The self-cleaning cooling component 7 is located inside the rotating ring 6 and is used to improve the heat dissipation speed of the magnet block 2. The self-cleaning cooling component 7 includes a fixed sleeve 71 fixedly connected to the high-temperature vessel 4, a rotating ring 6 movably connected to the fixed sleeve 71 via a bearing, an exhaust sleeve 72 connected to the fixed sleeve 71, a through hole 73 opened on the rotating ring 6, an air guide tube 74 connected to the fixed sleeve 71, a fan 75 installed inside the air guide tube 74, a timed lifting device 76 installed at the bottom of the air guide tube 74, a dust suction sleeve 77 connected to the timed lifting device 76 installed on the air guide tube 74, a brush plate 78 slidably connected inside the dust suction sleeve 77, and a self-cleaning dustproof component 79 installed on one side of the dust suction sleeve 77. The driven reciprocating component 8 is mounted on the dust collection sleeve 77 to improve the cleaning effect of the brush plate 78.

[0021] Specifically, the magnet block 2 is made of sintered neodymium iron boron, and there are 16 magnet blocks 2 in total. The central angle of each magnet block 2 is 22.5°. The surface of the magnet block 2 has a nickel-copper-nickel anti-corrosion coating, which is suitable for the humid and corrosive environment of the test scenario. The outer cylinder 1 is made of SUS430 stainless steel. The magnet block 2 and the outer cylinder 1 are bonded together with high-temperature resistant epoxy structural adhesive. The retaining ring 3 is installed inside the outer cylinder 1 by bolts. The driving device 5 includes a geared motor fixedly connected to the high-temperature reactor 4. The output end of the geared motor is fixedly connected to a gear. The bottom of the gear meshes with a gear ring. The gear ring is fixedly connected to the rotating ring 6. The rotating ring 6 is movably connected to the high-temperature reactor 4 through a bearing. The geared motor can drive the rotating ring 6 to rotate through the gear and the gear ring. The rotating ring 6 drives the magnet block 2 to rotate through the outer cylinder 1, forming a constant rotating magnetic field. The inside of the dust collection sleeve 77 has an opening for the brush plate 78 to slide. Several dust collection holes are opened on one side of the dust collection sleeve 77.

[0022] like Figures 3 to 6As shown, the timed lifting device 76 includes an arc-shaped sleeve 761 connected to the bottom of the air guide cylinder 74. An electric cylinder 762 is fixedly connected to the bottom of the arc-shaped sleeve 761. The output end of the electric cylinder 762 passes through the arc-shaped sleeve 761 and is fixedly connected to the bottom of the fan 75. A top plate 763 is fixedly connected to the top of the fan 75. The top end of the top plate 763 passes through the air guide cylinder 74 and is fixedly connected to the bottom of the dust collection sleeve 77. A time switch 764 is fixedly connected to one side of the arc-shaped sleeve 761, an exhaust hose 765 is connected to one side of the arc-shaped sleeve 761, and a filter assembly 766 is provided on one side of the arc-shaped sleeve 761.

[0023] Specifically, the time control switch 764 is a microcomputer time control switch, which can preset the lifting cycle; the electric cylinder 762 consists of a motor, a reciprocating lead screw, and a lifting rod. The motor can drive the lifting rod to move down and then up through the reciprocating lead screw. There is no need to control the forward and reverse rotation of the motor. The lifting control can be completed by controlling the start and stop time of the motor through the time control switch 764; the electric cylinder 762 drives the fan 75 and the top plate 763 to lift up and down, thereby driving the vacuum sleeve 77 to move precisely; the exhaust hose 765 timely discharges hot air, realizing timed automatic heat dissipation and cleaning without manual intervention, which is suitable for long-term testing needs.

[0024] like Figures 3 to 6 As shown, the filter assembly 766 includes a threaded cylinder 7661 connected to the arc-shaped sleeve 761. A cover plate 7662 is threadedly connected to the inside of the threaded cylinder 7661. A filter cylinder 7663 located inside the threaded cylinder 7661 is fixedly connected to one side of the cover plate 7662. One side of the threaded cylinder 7661 is connected to the vacuum sleeve 77 through a corrugated hose.

[0025] Specifically, the threaded cylinder 7661 is threadedly connected to the cover plate 7662, which facilitates disassembly and maintenance. The filter cylinder 7663 can intercept dust, iron filings and other impurities sucked in by the dust suction sleeve 77, preventing impurities from entering the arc sleeve 761 and the air guide cylinder 74 and damaging components such as the fan 75.

[0026] like Figures 3 to 6 As shown, the bottom of the dust collection cover 77 is fixedly connected to two symmetrically arranged limiting rods 9. The bottom end of the limiting rods 9 passes through the air guide tube 74 and is fixedly connected to the fan 75.

[0027] Specifically, the limiting rod 9 connects the vacuum sleeve 77 and the fan 75 to form a double guiding structure, which restricts the vacuum sleeve 77 to only move up and down along the axis, avoiding swaying or jamming during the lifting process, ensuring that the brush plate 78 always adheres to the surface of the outer cylinder 1 for cleaning, and at the same time ensuring that the fan 75 operates stably in the air guide cylinder 74, improving the accuracy of heat dissipation and cleaning actions.

[0028] like Figures 3 to 6As shown, the self-cleaning dustproof assembly 79 includes a sleeve plate 791 disposed on the top of the air guide cylinder 74. The top of the sleeve plate 791 is fixedly connected to the dust collection sleeve 77 via a connecting plate. A perforated disc 792 is movably connected to the inside of the sleeve plate 791 via a bearing. A brush plate 793 is fixedly connected to one side of the perforated disc 792. One side of the sleeve plate 791 is connected to the threaded cylinder 7661 via a corrugated hose. A filter screen 794 is fixedly connected to one side of the air guide cylinder 74.

[0029] Specifically, the sleeve 791 is fixed to the dust suction sleeve 77 via a connecting plate and rises and falls synchronously with the dust suction sleeve 77. After the fan 75 moves down to the designated position, the fan 75 can suck air from the sleeve 791 through the arc sleeve 761 and the threaded cylinder 7661. The sleeve 791 sucks away the impurities accumulated on the filter screen 794 through the perforated disc 792, and then filters them through the filter cylinder 7663 to prevent dust accumulation and blockage of the heat dissipation channel.

[0030] like Figures 3 to 6 As shown, the driven reciprocating component 8 includes a reducer 81 fixedly connected to the dust collection sleeve 77. The input end of the reducer 81 is fixedly connected to a rubber wheel 82. The output end of the reducer 81 extends into the interior of the dust collection sleeve 77 and is fixedly connected to an eccentric wheel 83. A square sleeve 84 is fitted on the eccentric wheel 83. One side of the square sleeve 84 is fixedly connected to the brush plate 78.

[0031] Specifically, the reducer 81 is a worm gear reducer. After the dust collection sleeve 77 moves down, the rubber wheel 82 contacts the outer cylinder 1. The rotation of the outer cylinder 1 can drive the rubber wheel 82 to rotate synchronously. Through the transmission of the reducer 81, the eccentric wheel 83 is driven to rotate. While rotating, the eccentric wheel 83 will push the square sleeve 84 and the brush plate 78 to move back and forth inside the dust collection sleeve 77, which will enhance the cleaning force of the brush plate 78 and effectively remove the firmly attached impurities on the surface of the outer cylinder 1, greatly improve the cleaning effect, and further ensure the stable heat dissipation of the magnet block 2.

[0032] like Figure 6 As shown, a guide rod 10 is fixedly connected inside the dust collection sleeve 77, a brush plate 78 is sleeved on the guide rod 10, a guide rod 21 is fixedly connected inside the dust collection sleeve 77, and a square sleeve 84 is sleeved on the guide rod 21.

[0033] Specifically, guide rod 10 provides directional control for brush plate 78, ensuring that brush plate 78 reciprocates smoothly only along the axial direction; guide rod 21 restricts the movement trajectory of square sleeve 84, preventing offset or jamming during transmission of eccentric wheel 83, and ensuring that brush plate 78 fits tightly against the surface of outer cylinder 1.

[0034] like Figures 4 to 7As shown, a rotating cleaning component 12 is provided on one side of the sleeve 791. The rotating cleaning component 12 includes a trapezoidal sleeve 121 fixedly connected to the sleeve 791. A rotating rod 122 is movably connected to the inside of the sleeve 791 through a bearing. One end of the rotating rod 122 is fixedly connected to the perforated plate 792. An arc-shaped plate 123 located inside the trapezoidal sleeve 121 is fixedly connected to the rotating rod 122. One end of the exhaust hose 765 is connected to the trapezoidal sleeve 121.

[0035] Specifically, both brush plate 78 and brush plate 793 are wear-resistant fiber brush plates; the air discharged from the exhaust hose 765 enters the trapezoidal sleeve 121, which drives the arc plate 123 to rotate, thereby driving the rotating rod 122 and the perforated disc 792 to rotate within the sleeve plate 791, so that brush plate 793 can perform a rotating cleaning action, which can thoroughly clean the attached impurities on the filter screen 794, and at the same time facilitate the perforated disc 792 to perform dust suction on different positions of the filter screen 794, further improving the self-cleaning and heat dissipation effects.

[0036] like Figures 1 to 4 As shown, a control component 13 is provided on the air cylinder 74. The control component 13 includes an L-shaped plate 131 fixedly connected to the air cylinder 74. A switch 132 is fixedly connected inside the L-shaped plate 131. A pressure plate 133 is fixedly connected to one side of the dust collection sleeve 77. The top of the pressure plate 133 contacts the bottom of the switch 132. A switch 2 134 is fixedly connected to the air cylinder 74.

[0037] Specifically, both switch 132 and switch 2134 are momentary switches, and both are electrically connected to fan 75. L-shaped plate 131 provides mounting support for switch 132. After the dust cover 77 rises to the specified height, pressure plate 133 presses switch 132, and fan 75 starts to dissipate heat. During the downward movement of dust cover 77, pressure plate 133 disengages from switch 132 and turns off fan 75. When dust cover 77 descends to the cleaning position, pressure plate 133 presses switch 2134 to restart fan 75, realizing the linkage control between fan 75 and cleaning action. This avoids fan 75 running idly and also prevents airflow turbulence caused by continuous fan rotation, which could cause dust on filter screen 794 and filter cartridge 7663 to scatter.

[0038] Working principle and usage process of this invention: When in use, after the drive device 5 is started, it will drive the outer cylinder 1 and the internal magnet block 2 to rotate synchronously through the rotating ring 6, forming a constant rotating magnetic field, which provides a stable and uniform magnetic field environment for the test area inside the high temperature reactor 4, meeting the corrosion test requirements of special steel. When cooling is required, the electric cylinder 762 is activated, which drives the fan 75, top plate 763, and dust collection sleeve 77 to rise to the specified height. At this time, the pressure plate 133 presses the switch 132 and then closes the electric cylinder 762. The switch 132 activates the fan 75 to generate directional airflow. The airflow enters the fixed sleeve 71 through the air guide tube 74, passes through the through hole 73 on the rotating ring 6, and is discharged. When the airflow passes through the outer cylinder 1, it will carry away the heat on the magnet block 2. At the same time, some air is discharged through the exhaust sleeve 72, thereby cooling the surface of the rotating outer cylinder 1 and carrying away the heat generated by the magnet block 2 due to thermal conduction. Meanwhile, the filter screen 794 filters the airflow entering the air guide tube 74. When the preset cleaning cycle is reached, the timer switch 764 triggers the electric cylinder 762 to drive the fan 75, top plate 763 and dust cover 77 to move downwards. During the movement, the pressure plate 133 disengages from the switch 132, and the fan 75 is temporarily turned off. When the dust cover 77 moves down to the cleaning position, the rubber wheel 82 is in close contact with the surface of the rotating outer cylinder 1. The rotation of the outer cylinder 1 drives the rubber wheel 82 to rotate synchronously. The torque of the rubber wheel 82 is reduced by the reducer 81 and then transmitted to the eccentric wheel 83. When the eccentric wheel 83 rotates, it pushes the square sleeve 84 to reciprocate along the guide rod 11. The square sleeve 84 then drives the brush plate 78 to reciprocate along the guide rod 10, closely adhering to the surface of the outer cylinder 1 to clean the attached dust, iron filings and other impurities.

[0039] At the same time, the pressure plate 133 presses the switch 134, the fan 75 restarts, and a directional airflow is formed in the arc sleeve 761, which sucks the impurities generated during cleaning into the dust collection sleeve 77. The impurities are transported through the corrugated hose to the threaded cylinder 7661 of the filter assembly 766, where they are intercepted and collected by the filter cylinder 7663, achieving a self-cleaning and cooling effect.

The fan 75 is installed inside the air guide tube 74. Finally, the timed lifting device 76 is installed at the bottom of the air guide tube 74, so that the timed lifting device 76 is connected to the fan 75. S3: Install the vacuum sleeve 77 onto the timed lifting device 76, install the driven reciprocating component 8 onto the vacuum sleeve 77 and connect it to the brush plate 78, check the reliability of the connection and movement of each component, and complete the final assembly.
