[0027] The following is combined with Figure 1 To Attachment Figure 7 And specific embodiments describe the present invention in detail.

[0028] like Figures 1 to 4 As shown, the utility model provides a desulfurization tower side agitator, comprising a support frame 2 fixedly connected to the side wall of the desulfurization tower 1, the side wall of the desulfurization tower 1 is provided with a reserved hole 11, and a connecting hole 21 is provided on the side of the support frame 2 close to the desulfurization tower 1. A rotating rod 3 passes through the reserved hole 11 and the connecting hole 21, and a mechanical seal body 31 is sleeved on the rotating rod 3. The outer wall of the mechanical seal body 31 is respectively plugged with the reserved hole 11 and the connecting hole 21, and the mechanical seal body 31 is used to seal the reserved hole 11.

[0029] One end of the rotating rod 3 placed inside the desulfurization tower 1 is fixedly connected to a stirring rod 32, and a mounting hole 22 is provided on the side of the support frame 2 away from the desulfurization tower 1. The rotating rod 3 is sleeved with a first support bearing 33, which is plugged into the mounting hole 22, and the first support bearing 33 supports the rotating rod 3.

[0030] The top inner wall and the bottom inner wall of the support frame 2 are respectively fixedly connected with support plates 23 . The rotating rod 3 is sleeved with a second support bearing 34 . The second support bearing 34 abuts against the support plate 23 . The second support bearing 34 increases the stability of supporting the rotating rod 3 .

[0031] The end of the rotating rod 3 away from the desulfurization tower 1 is connected to the first transmission wheel 35, and a disassembly assembly 4 is provided between the first transmission wheel 35 and the rotating rod 3, and the disassembly assembly 4 connects the first transmission wheel 35 with the rotating rod 3. A support frame 5 is fixedly connected to the upper surface of the support frame 2, and a driving motor 51 is fixedly connected to the upper surface of the support frame 5. The output shaft of the driving motor 51 is fixedly connected to the second transmission wheel 511, and a belt 512 is connected between the first transmission wheel 35 and the second transmission wheel 511.

[0032] The output shaft of the driving motor 51 drives the second transmission wheel 511 to rotate, and the second transmission wheel 511 drives the first transmission wheel 35 to rotate through the belt 512. The first transmission wheel 35 drives the rotating rod 3 and the stirring rod 32 to rotate, and the stirring rod 32 stirs the slurry inside the desulfurization tower 1.

[0033] The rotating rod 3 is fixedly connected with a baffle 36 , and a sealing ring 361 is fixedly connected to a side of the baffle 36 close to the mechanical seal body 31 .

[0034] When the mechanical seal body 31 needs to be replaced, the belt 512 is separated from the first transmission wheel 35, and the disassembly assembly 4 releases the restriction on the first transmission wheel 35, and the first transmission wheel 35 is separated from the rotating rod 3. Move the rotating rod 3 to the side away from the desulfurization tower 1. When the mechanical seal body 31 is not completely separated from the connecting hole 21, the sealing ring 361 has abutted against the inner wall of the desulfurization tower 1. At this time, the sealing ring 361 seals the reserved hole 11. Since the sealing ring 361 has elasticity, when the mechanical seal body 31 is completely separated from the connecting hole 21, the sealing ring 361 continues to be squeezed, and the sealing ring 361 is tightly abutted against the inner wall of the desulfurization tower 1.

The chuck 6 supports the rotating rod 3, reducing the possibility of the rotating rod 3 tilting during the replacement of the mechanical seal body 31, thereby reducing the possibility of leakage due to the gap between the sealing ring 361 and the inner wall of the desulfurization tower 1 due to the tilt of the rotating rod 3.

[0036] After the mechanical seal body 31 is replaced, the second support bearing 34 is connected to the rotating rod 3, the first support bearing 33 is connected to the rotating rod 3, the first transmission wheel 35 is connected to the rotating rod 3 through the disassembly assembly 4, the first bolt 62 is separated from the support frame 2, the chuck 6 is separated from the rotating rod 3, and then the rotating rod 3 is moved to the side close to the desulfurization tower 1, so that the mechanical seal body 31 is placed in the reserved hole 11 and the connecting hole 21 again, and then the belt 512 is respectively connected to the first transmission wheel 35 and the second transmission wheel 511.

The second bolt 43 fixes the fixing block 41 in the fixing groove 42, thereby connecting and fixing the first transmission wheel 35 to the rotating rod 3.

When the rotating rod 3 is not required to move along the axis of the rotating rod 3, the limiting assembly 7 limits the rotating rod 3 to reduce the possibility of the rotating rod 3 moving along the axis of the rotating rod 3.

[0042] When the mechanical seal body 31 needs to be replaced, the plug-in rod 76 is separated from the second plug-in groove 75, and the second limit rod 73 is moved downward to separate the second limit rod 73 from the first limit groove 77. The second limit rod 73 releases the restriction on the rotating rod 3, and the rotating rod 3 can be moved to the side away from the desulfurization tower 1.

[0043] The first limiting rod 71 has a side on which the plug hole 74 is connected to a fixing assembly 8 , and the fixing assembly 8 is connected to the plug rod 76 , thereby increasing the stability of the plugging of the fixing rod 81 and the second plug slot 75 .

When the plug-in rod 76 is plugged into the second plug-in slot 75, the fixing plate 82 is rotated so that the fixing plate 82 abuts against a side of the plug-in rod 76 away from the second limiting rod 73, and the fixing plate 82 reduces the possibility of the plug-in rod 76 being separated from the second plug-in slot 75, and increases the stability of the plug-in rod 76 being plugged into the second plug-in slot 75. The fixing plate 82 is rotated to separate the fixing plate 82 from the plug-in rod 76, and the plug-in rod 76 can be separated from the second plug-in slot 75.
