The diameter of the funnel-shaped filter screen 14 is gradually reduced from top to bottom, so that the contact area of the wastewater and the filter screen is increased and the filtering efficiency is improved compared with the conventional cylindrical filter screen; and the side surface of the filter screen is an inclined surface, so that water flows downwards along the inner side of the filter screen, the inner surface of the filter screen is washed under the action of gravity, and the anti-blocking effect is good.
In the operation process of the waste water resin catcher, because the flow rate of water is overlarge, the water pressure is overhigh or the operation time is longer, the resin is inevitably worn and broken, and small particles of resin are easy to block in gaps of the filter screen, so that the pressure difference between an inlet and an outlet of the catcher is increased. When broken resin is accumulated on the surface of the filter screen to cause the pressure difference between an inlet and an outlet to be increased to a set value, the pressure difference transmitter 2 sends a signal, the electric control box 3 drives the motor 6 to drive the horizontal rotating brush 12 and the vertical rotating brush 13 to start to rotate through the transmission shaft 9, and the stainless steel brush hairs 4 on the rotating brush clean the resin on the surface of the funnel-shaped filter screen 14 and collect the resin at the bottom of the catcher. When the pressure difference between the inlet and the outlet of the filter returns to normal, the motor 6 stops rotating. When the resin is observed to a certain height from the sight glass 16, the grease discharge port 17 is opened, and the cleaned resin is discharged from the bottom of the trap.
