[0002] The condenser is a core auxiliary equipment of thermal power generating units, and its heat exchange efficiency directly affects the vacuum degree and operation economy of the unit. The rubber ball cleaning system is a core device that maintains the cleanliness of the inner wall of the condenser cooling water pipe and reduces the heat exchange thermal resistance. A rubber ball pump drives rubber balls to enter the cooling water pipe along with circulating water, and the dirt on the inner wall is removed by the friction between the rubber balls and the pipe wall, so as to ensure the heat exchange effect.

[0003] During long-term cyclic use, rubber balls will have problems such as wear, aging, diameter shrinkage, breakage and deformation. Failed unqualified rubber balls cannot fully contact the inner wall of the cooling water pipe, lose cleaning capacity, and may also cause blockage of the cooling water pipe and jamming of the rubber ball pump, which seriously affects the safe and stable operation of the system. Therefore, a supporting rubber ball sorting device is required to screen and remove failed rubber balls. As an important supporting component of the rubber ball cleaning system, the rubber ball sorting device is used to screen failed rubber balls generated during cyclic use to ensure the safe and stable operation of the system.

The pressure reducing pump 44 adjusts the internal pressure of the water-ball separation unit 43, and the rubber balls slide towards the feeding bend 42 by their own weight. The rubber balls enter the rotating filter cartridge 11 through the feed bin 16. The motor 14 drives the filter cartridge to rotate through the sprocket 15, electric roller 12, and circular track 13. Defective rubber balls fall into the defective product collection box 3 through the waste outlet 70, while qualified rubber balls enter the good product collection box 2 through the collection pipe 21. Qualified rubber balls are circulated back to the rubber ball pump via the feeding pipe 22.
