[0028] When installing the electrostatic filter, the filter module 3 is placed on the placement frame 2, and the filter module 3 is attached to the suction cup 15, and then the vacuum pump 14 is turned on. After that, the vacuum pump 14 forms a negative pressure state inside the suction cup 15, so that the suction cup 15 is fixed on one side of the filter module 3, and then the servo motor 6 is turned on, and then the output end of the servo motor 6 drives the rotating shaft 7 to rotate, and then the rotating shaft 7 drives the moving block 8 to rotate, and then the moving block 8 is subjected to the resistance of the limit rod 16, so that the moving block 8 moves to the left along the outer surface of the rotating shaft 7, and then the moving block 8 drives the connecting block 10 to move to the left through the electric telescopic rod 9, and then the connecting block 10 drives the suction cup 15 to move to the left through the connecting frame 13 , and then the suction cup 15 drives the filter module 3 to move to the left, thereby moving the filter module 3 into the shell 1. When most of the filter modules 3 enter the shell 1, by turning off the vacuum pump 14, turning on the electric telescopic rod 9, and then the telescopic rod of the electric telescopic rod 9 drives the connecting block 10 to move downward, and then the connecting block 10 drives the suction cup 15 to move downward through the connecting frame 13, the suction cup 15 is separated from the filter module 3, and the suction cup 15 is recovered into the placement frame 2, and then the filter module 3 is pushed to make it all enter the shell 1, which is convenient for installing the filter module 3 and improves the installation efficiency. At the same time, it avoids the collision with the shell 1 during the installation of the filter module 3, causing damage and reducing the service life of the device.
