[0025] refer to Figures 1-11 A device for cleaning a clogged slag kettle in the production of 4,4'-diaminodiphenyl ether provided by an embodiment of the present invention is now described. The device comprises a base plate 1, a collecting hopper 4 being fixedly connected to the upper end of the base plate 1, an angle adjustment mechanism 6 being provided at the upper end of the collecting hopper 4, a first power mechanism 7 being provided within the angle adjustment mechanism 6, a lifting mechanism 8 being provided at the upper end of the angle adjustment mechanism 6, and the first power mechanism 7 being used to provide power to the lifting mechanism 8; a second power mechanism 9 being provided at the upper end of the angle adjustment mechanism 6, a connecting assembly 10 and a cleaning head 11 being provided at the upper end of the second power mechanism 9, and the second power mechanism 9 being connected to the cleaning head 11 via the connecting assembly 10.

[0026] When in use, the bottom plate 1 is transferred to the bottom of the discharge pipe 13 of the slag kettle, and then the first power mechanism 7 works to provide power for the lifting mechanism 8, and then the cleaning head 11 is driven to move upward with the cooperation of the connecting component 10, so as to facilitate the cleaning head 11 to extend into the interior of the discharge pipe 13. When the cleaning head 11 extends into the interior of the discharge pipe 13, the second power mechanism 9 works to drive the cleaning head 11 to rotate. As the cleaning head 11 rotates, the slag inside the discharge pipe 13 can be crushed, so that the slag inside the discharge pipe 13 can fall and fall to the receiving container. The inside of the collecting bucket 4 is finally discharged from the bottom of the collecting bucket 4, so as to achieve the purpose of cleaning the discharge pipe 13, so that when cleaning the discharge pipe 13 of the slag kettle, no manual cleaning is required, thereby reducing the work intensity. When the cleaning head 11 rotates, the angle adjustment mechanism 6 works, so that the lifting mechanism 8, the second power mechanism 9 and the cleaning head 11 are deflected, which is conducive to the cleaning head 11 to be close to the inner wall of the discharge pipe 13, and the inner wall of the discharge pipe 13 can be better cleaned; at the same time, with the cooperation of the connecting component 10, it is convenient to replace the cleaning head 11.

[0027] The angle adjustment mechanism 6 includes a support plate 601, a first motor 602, a first bearing seat 603, a worm 604, a worm wheel 605, a mounting bracket 606 and a first rotating shaft 607. The front and rear sides of the upper end of the collecting bucket 4 are fixedly connected to the support plate 601. The internal rotation of the support plate 601 is connected to the first rotating shaft 607. The mounting bracket 606 is fixedly connected between the two first rotating shafts 607. The front end of the front support plate 601 is fixedly connected to the first motor 602 and the first bearing seat 603. The internal rotation of the first bearing seat 603 is connected to the worm 604.

When the inner wall of the discharge pipe 13 needs to be cleaned, the first motor 602 works. At this time, the first rotating shaft 607 is driven to rotate with the cooperation of the worm 604 and the worm wheel 605, thereby driving the mounting bracket 606 to rotate. As the mounting bracket 606 rotates, the cleaning head 11 is driven to deflect with the cooperation of the lifting mechanism 8, the second power mechanism 9 and the connecting assembly 10, so that the cleaning head 11 is in close contact with the inner wall of the discharge pipe 13, thereby improving the cleaning effect.

There are two first bevel gears 703, which are symmetrically distributed on the second rotating shaft 702. The upper end of the first bevel gear 703 is engaged with the second bevel gear 704; the left end of the mounting frame 606 is fixedly connected to the second motor 701, and the output end of the second motor 701 is fixedly connected to the second rotating shaft 702. When the second motor 701 is working, it can provide power for the lifting mechanism 8 with the cooperation of the second rotating shaft 702, the first bevel gear 703 and the second bevel gear 704.

[0029] The lifting mechanism 8 includes a support frame 801, a threaded rod 802 and a movable plate 803. The upper end of the mounting frame 606 is fixedly connected to the support frame 801, and the internal rotation of the support frame 801 is connected to the threaded rod 802. The lower end of the threaded rod 802 passes through the mounting frame 606 and is rotatably connected to the mounting frame 606.

There are two threaded rods 802, which are symmetrically distributed on both sides of the interior of the support frame 801. The external threads of the two threaded rods 802 are in opposite directions. During operation, as the second bevel gear 704 rotates, the threaded rod 802 is driven to rotate, causing the movable plate 803 to move. When the movable plate 803 moves up, the cleaning head will enter the interior of the discharge pipe 13, thereby facilitating the cleaning of the interior of the discharge pipe 13.

The output end of the third motor 901 passes through the second bearing seat 902 and is rotatably connected to the second bearing seat 902. The output end of the third motor 901 is fixedly connected to the third bevel gear 903; the inner rotation of the mounting frame 606 is connected to the third rotating shaft 904, and the circumferential surface of the third rotating shaft 904 is fixedly connected to the fourth bevel gear 905, and the fourth bevel gear 905 is meshed with the third bevel gear 903. The upper end of the third rotating shaft 904 is fixedly connected to the transmission shaft 906, and the end of the transmission shaft 906 is hexagonal; the internal rotation of the movable plate 803 is connected to the transmission cylinder 907, and the transmission cylinder 907 is slidingly connected to the transmission shaft 906. The upper end of the transmission cylinder 907 passes through the support frame 801 and is slidingly connected to the support frame 801. When the third motor 901 is working, the third rotating shaft 904 is driven to rotate with the cooperation of the third bevel gear 903 and the fourth bevel gear 905, thereby driving the transmission shaft 906 to rotate. As the transmission shaft 906 rotates, the transmission cylinder 907 rotates, and then the cleaning head 11 is driven to rotate with the cooperation of the connecting assembly 10, thereby facilitating the cleaning head 11 to perform crushing operations.

[0031] Both sides of the support frame 801 are fixedly connected with blocks 12. The height of the upper end surface of the block 12 is higher than the upper end of the third motor 901. By setting the block 12, when working, the block 12 acts as a block to prevent the moving plate 803 from pressing on the third motor 901.

When working, when the cleaning head 11 needs to be replaced, the lifting mechanism 8 descends, driving the transmission cylinder 907 to move downward. When the movable plate 1007 contacts the support frame 801, as the transmission cylinder 907 continues to move downward, it will squeeze the movable plate 1007 to move upward, thereby driving the limiting rod 1005 to move outward under the cooperation of the transmission rod 1006, so that the limiting rod 1005 is separated from the limiting groove 1003, thereby releasing the limitation of the plug-in block 1002, making it easy to remove the plug-in block 1002 from the inside of the socket 1001, achieving the purpose of disassembly. The purpose of removing the cleaning head 11 is that the upward movement of the movable disk 1007 will compress the spring 1008, and the compressed spring 1008 is conducive to the resetting of the movable disk 1007; when the cleaning head 11 is removed, the new cleaning head 11 is installed inside the socket 1001, and then the lifting mechanism 8 rises. At this time, under the action of the compressed spring 1008, it is convenient for the limiting rod 1005 to be inserted into the limiting groove 1003, realizing the limitation of the socket 1002, thereby achieving the purpose of installing the cleaning head 11 and making the cleaning head 11 easy to disassemble and assemble.
