Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a condensate discharge device for boilers. Background Art

[0002] During the operation of a gas boiler, when the flue gas is at the tail of the chimney, due to the temperature drop, the water vapor inside the flue gas will condense into condensate. These condensates need to be discharged in time by a discharge device. Otherwise, they will flow into the boiler along the chimney, thus affecting the normal operation of the boiler. And after filtering and treating these condensates, they can be reused to reduce waste.

[0003] A condensate discharge device for boilers described in the published patent No. CN217520068U includes a discharge assembly and a boiler. The discharge assembly includes a purification tank. A filter cage is arranged in the middle of the purification tank. A water inlet pipe and a water outlet pipe are respectively fixedly installed on the surface of the purification tank. The water inlet pipe extends into the filter cage and is communicated with the filter cage. The water outlet pipe is communicated with the water inlet pipe of the boiler. A chimney is arranged on the surface of the boiler. A U-shaped pipe is fixedly installed in the middle of the chimney. The U-shaped pipe is communicated with the water inlet pipe through a water guide pipe. A cleaning assembly is arranged inside the filter cage. In this discharge device, by setting the discharge assembly, when condensate is generated in the chimney, the condensate will enter the water inlet pipe and then enter the filter cage inside the purification tank. At this time, the impurities inside the condensate will be intercepted inside the filter cage, and the clean condensate will flow out from the water outlet pipe and then enter the boiler from the water inlet of the boiler. In this way, the full utilization of condensate can be realized, and water resources can be greatly saved. However, there are still defects in the prior art:

[0004] 1. When cleaning the filter cage in the prior art, the electric valve will be opened, and the impurities inside the filter cage will flow out along the filter cage. However, at this time, the water outlet pipe is not closed, so the water containing impurities during cleaning will also flow out from the water outlet pipe, polluting the water discharged from the water outlet pipe.

[0005] 2. In the prior art, the driving motor drives the transmission shaft to rotate, and the transmission shaft drives the scraper to scrape inside the filter cage, so as to scrape off the impurities on the inner wall of the filter cage. However, the scraper is arranged inside the filter cage and will also be polluted. If it is not thoroughly cleaned for a long time, bacteria are likely to breed, polluting the discharged condensate.
