[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] like Figure 1 As shown,

[0018] A filtering system for condensate water for a cogeneration boiler, characterized in that it includes a frame 2, a filter box 3 is fixedly connected to the upper end of the frame 2, a first water inlet 4 is provided at the upper end of the filter box 3, a first drive motor 5 is provided on the filter box 3, a turntable 6 is fixedly connected to the output shaft of the first drive motor 5, a plurality of magnets 7 are fixedly connected to the lower end of the turntable 6, a first water outlet 8 is provided at the lower end of the filter box 3, an insulation box 9 is fixedly connected to the lower end of the frame 2, a second water inlet 10 is provided at the upper end of the insulation box 9, a second water outlet 11 is provided at the lower end of the insulation box 9, and a filter assembly is provided between the first water outlet 8 and the second water inlet 10.

[0019] In this embodiment, condensed water enters the filter box 3 from the first water inlet 4, and the first drive motor 5 is started to drive the turntable 6 and the magnet 7 to rotate, so as to stir the condensed water, so as to facilitate the adsorption of iron filings in the condensed water on the magnet 7. After the iron filings in the condensed water are processed, the condensed water is discharged from the first water outlet 8, passes through the filter assembly, and enters the insulation box 9 from the second water inlet 10 for storage, so that the condensed water is kept warm. When needed, it is sent to the boiler from the second water outlet 11 for circulation. Not only is the condensed water filtered and used, but the loss of heat energy of the condensed water is also reduced.

[0020] In this embodiment, a scraper 12 is slidably provided on the magnet 7, and the upper end of the scraper 12 is connected to the turntable 6 through a spring 13. A push rod motor 14 is symmetrically provided on the filter box 3. The push rod of the push rod motor 14 can push the scraper 12 down to scrape off the iron filings adsorbed on the magnet 7. A first collection box 15 is slidably connected to the filter box 3. After the condensed water is filtered, a large amount of iron filings are adsorbed on the surface of the magnet 7. The push rod motor 14 is used to push the scraper 12 down to scrape off the iron filings adsorbed on the magnet 7. The iron filings fall into the first collection box 15 for collection. The first collection box 15 is slid out to take out the iron filings for recycling. After the push rod of the first push rod motor 14 is reset, the scraper 12 is reset by the elastic force of the spring 13.

[0021] In this embodiment, the filtering assembly includes two second drive motors 16, which are symmetrically arranged on the frame 2. A filter screen 17 is fixedly connected to the output shaft of the second drive motor 16, and a second collection box 18 is arranged below the filter screen 17. The second drive motor 16 drives the filter screen 17 to rotate, so that the two filter screens 17 filter alternately. When one filter screen 17 is in use, the second drive motor 16 drives the other filter screen 17 to rotate, and the impurities intercepted on the filter screen 17 are poured into the second collection box 18, thereby ensuring the filtering efficiency and effect.

[0022] In this embodiment, baffles 19 are symmetrically provided on both sides of the frame 2, and a rubber layer is provided on the baffles 19. When the filter 17 rotates to dump impurities, some impurities will be stuck on the filter 17. At this time, the second drive motor 16 drives the filter 17 and the baffle 19 to collide with each other, and the impurities stuck on the filter 17 are shaken off. The rubber layer provided on the baffle 19 is beneficial to protect the filter 17.

[0023] In this embodiment, a heat preservation liner is provided in the heat preservation box 9. The heat preservation box 9 is provided with a heat preservation liner to improve the heat preservation effect.

[0024] In this embodiment, solenoid valves 20 are provided on the first water outlet 8 and the second water outlet 11 .
