[0031] Working principle: Before using this new type of circular electrostatic precipitator distribution plate hanging limit shock absorbing device, it is necessary to first check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, firstly, the H-shaped steel body 102 is welded and installed with the side wall of the conical air outlet, and then the hanging beam 101 is inserted into the H-shaped steel body 102 through the opening 201, and then the pin 202 is passed through the hanging beam 101, and then the shock-absorbing sleeve 203 is sleeved on the outside of the pin 202 from both sides of the H-shaped steel body 102; the opening 201 can play a limiting role to reduce the forward and backward movement of the hanging beam 101;

[0032] Then, the swing plate 209 is rotated and pulled to rotate the rotating plate 205, so that the steel column 207 moves along the curved groove 206, so that the steel column 207 drives the arch block 208 to slide from the outside to the inside of the shock-absorbing sleeve 203, so that the curved clip 212 fits the pin 202, so that the pins 202 of different diameters can be effectively abutted, thereby ensuring that the vibration energy of the pin 202 is limitedly transmitted to the springs and rubber sleeves 214, and finally achieving effective shock absorption, and avoiding the deformation or even breakage of the hanging point;

[0033] At this time, the fixing block 213 can be connected to the shock-absorbing sleeve 203 by bolts to prevent the position of the shaking plate 209 from changing. The device installation is relatively simple and convenient, and the difficulty of later maintenance is low, which ensures the stability of the hanging beam 101 of the distribution plate, so that the dust collector as a whole can operate more efficiently.

[0034] When vibrating, the hanging beam 101 will drive the pin 202 to move up and down, and the pin 202 will move by squeezing the curved clip 212 and shrink the second spring 216, and at the same time, the connecting plate 211 will rotate and drive the sliding sleeve 210 to slide along the straight rod 217, thereby squeezing the first spring 215, and reducing the kinetic energy after the sliding sleeve 210 hits the rubber sleeve 214, and finally reducing the vibration of the pin 202;

[0035] Then, the mounting side plate 308 is inserted into the guide side plate 301, and the plug plate 302 is inserted into the guide groove 303, and then the rotating rod 305 is rotated to make the sliding column 306 slide into the embedding groove 304. At this time, the mounting side plate 308 can be stably connected to the H-shaped steel body 102, and finally the shock-absorbing sleeve 203 and the pin shaft 202 can be prevented from falling off due to long-term vibration.
