However, the bolts on the existing flange are fixed by threaded connection, and the equipment will vibrate during operation, which will cause the bolts to loosen over time. Therefore, we propose a magnetic sealing transmission device for top-entry kettles. Utility Model Content

[0011] The beneficial effects of the present invention are:

[0012] 1. By turning the adjusting screw, the mounting sleeve moves, causing the balls on the sleeve to roll along the inner wall of the retaining groove, squeezing the clamping block. This design allows the clamping block to slide along the slide rod and eventually insert its tip into the slot, providing a secondary reinforcement for the bolt.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, a magnetic sealing transmission device for a top-entry kettle includes an isolation sleeve 1, an outer magnetic rotor 2, an inner magnetic rotor 3, a transmission shaft 4, a machine base 5, a bearing seal 6, a coupling 7 and an oil circuit 8. The outer magnetic rotor 2 is installed on the outside of the isolation sleeve 1, and the inner magnetic rotor 3 is installed inside the isolation sleeve 1. The transmission shaft 4 is connected to the inner magnetic rotor 3 and is used to transmit the torque transmitted by the outer magnetic rotor 2 to the driven equipment. The machine base 5 is fixedly installed with the outer magnetic rotor 2 and the isolation sleeve 1. The bearing seal 6 is arranged at the outlet portion of the transmission shaft 4 and is used to prevent the medium from leaking through the transmission shaft 4. The coupling 7 is connected to one end of the transmission shaft 4 and is used to transmit the rotational motion of the transmission shaft 4 to the driven equipment. The oil circuit 8 is used to provide lubricating oil to the bearing seal 6. The working principle of the above structure is the same as that of the prior art and will not be described in detail.

[0022] like Figure 2-Figure 5As shown, it also includes a connecting flange 9, which is arranged at the end of the isolation sleeve 1 and is used to connect to the kettle body or other equipment. Bolts 12 are inserted into the connecting holes of the connecting flange 9, and the outer walls of multiple bolts 12 are threadedly connected with nuts 13. The outer wall of the isolation sleeve 1 is provided with multiple through holes 10, and the inner walls of multiple through holes 10 are provided with two card slots 11. The ends of the bolts 12 are threadedly connected with adjusting screws 14, and the ends of the adjusting screws 14 are rotatably connected with the mounting sleeve 16. The outer walls of the bolts 12 are provided with movable cavities 15, and the inner walls of the movable cavities 15 are provided with Two slide slots 18 are provided, and the inner walls of the slide slots 18 are fixedly connected to slide rods 23. Springs 24 are sleeved at both ends of the slide rods 23, and sliders 25 are slidably connected to both ends of the slide rods 23. Two clamping blocks 20 are provided inside the movable chamber 15, and the two sides of the clamping blocks 20 are fixedly connected to the sliders 25. One end of the clamping block 20 has a tip 22, which engages with the corresponding clamping slot 11. The other end of the clamping block 20 has an arc end 21. One end of the spring 24 is fixedly connected to the slider 25, and the other end of the spring 24 is fixedly connected to the inner wall of the slide slot 18. By rotating the adjusting screw 14, the mounting sleeve 16 is pushed to move, and the ball 17 on the mounting sleeve 16 rolls along the inner wall of the limiting groove 19, exerting a squeezing effect on the clamping block 20. This design enables the block 20 to slide along the slide rod 23 and eventually insert the tip 22 into the slot 11, thereby achieving secondary reinforcement of the bolt 12. This double fastening mechanism significantly enhances the connection strength between the bolt 12 and the connecting flange 9 and the isolation sleeve 1, and can delay the occurrence of loosening of the bolt 12.

[0023] like Figure 3 and Figure 4 As shown, rotatable balls 17 are embedded at both ends of the mounting sleeve 16 , and the two balls 17 are in rolling contact with the limiting grooves 19 respectively. Two limiting grooves 19 are provided on the inner wall of the movable cavity 15 .

[0024] Working principle: During the installation of the device, multiple bolts 12 are respectively passed through the connecting flange 9 on the connecting device and the corresponding holes on the isolation sleeve 1. The isolation sleeve 1 is fixed to the connecting flange 9 of the connecting device by screwing the nuts 13 on the multiple bolts 12. By rotating the adjusting screw 14, the mounting sleeve 16 is pushed to move by the adjusting screw 14, so that the mounting sleeve 16 drives the ball 17 at the end to roll along the inner wall of the limit groove 19, and the arc ends 21 on the two blocks 20 are squeezed by the mounting sleeve 16. At this time, the two blocks 20 respectively drive the slider 25 to slide along the slide rod 23 until the tip 22 on the block 20 is inserted into the inside of the slot 11, thereby further reinforcing the bolt 12, thereby effectively reducing the impact of loosening of the bolt 12 due to vibration.
