Specific implementation method:

[0015] like Figure 1 As shown, a filtering device for a circulating cooling water pipeline comprises a filter box 1, at both ends of which are respectively connected an inlet pipe 2 and an outlet pipe 3, a filter screen 8 is installed in the filter box 1, a drain pipe 4 is connected to the bottom of the filter box 1, the drain pipe 4 can be made of a transparent material, the drain pipe 4 is located between the inlet pipe 2 and the filter screen 8, a sealing cover 7 is installed at the outlet of the drain pipe 4, a pneumatic clearing device and a ball valve 14 are installed on the outlet pipe 3, and the pneumatic clearing device is used to clean a blocked filter screen 8.

[0016] like Figure 2 As shown, the filter screen 8 is easy to disassemble and install, the filter box 1 and the water outlet pipe 3 are connected by bolts, the filter box 1 and the water outlet pipe 3 clamp and fix the filter screen 8, and sealing rings 9 are installed on both sides of the filter screen 8.

[0017] like Figure 3As shown, the pneumatic clearing device includes an air cylinder 11, which is hinged on the water outlet pipe 3, and a piston rod is slidably connected in the air cylinder 11, an air outlet pipe 12 is connected to the air cylinder 11, and an air inlet pipe 13 is connected to the air outlet pipe 12, and a one-way valve 15 is installed in the air outlet pipe 12 and the air inlet pipe 13, an inflation hole matching the position of the air outlet pipe 12 is opened on the air outlet pipe 12, and a sealing plug 10 is plugged in the inflation hole; a rubber ring gasket 16 is installed at the orifice of the inflation hole.
