Description

Technical Field

[0001] The utility model belongs to the technical field of boilers, and in particular relates to a vacuum gas-fired hot water boiler. Background Art

[0002] A vacuum boiler is a hot water boiler, also called a vacuum water heater. It is based on the basic principle of the vacuum boiler invented by the Swiss Federal Institute of Technology in 1972. The vacuum boiler is mainly used for civil heating, and can be used in hotels, residential areas, commercial places and other occasions for heating and sanitary hot water heating.

[0003] During the use of existing vacuum gas hot water boilers, although the scale on the inner wall of the boiler can be scraped off, the calcium and magnesium ions in the water body cannot be processed, which not only reduces the water quality, but also the hot water containing calcium and magnesium ions will be discharged through the pipe, which can easily cause scale to accumulate on the inner wall of the pipe. When the scale in the pipe accumulates too much, it will not only affect the normal drainage function of the boiler, but also the scale will corrode the pipe, causing internal wear of the pipe and eventually rupture, reducing the service life of the pipe.

[0023] It should be noted that this vacuum gas hot water boiler can filter the discharged hot water through the filter cartridge 16 when in use, so as to reduce the scale contained in the hot water, which not only improves the water quality of the hot water, but also reduces the accumulation of scale in the drain pipe after the filtered hot water is discharged, thereby extending the service life of the pipe. The scale filtered by the filter cartridge 16 will accumulate inside the annular box 5, and the accumulated stains will be discharged through the drain pipe when the valve is opened.

[0024] Example 2

[0025] Combination Figure 1 - Figure 5As shown, the difference between this embodiment and embodiment 1 is that: a cleaning mechanism used in conjunction with a filtering mechanism is installed inside the boiler body 1, and the cleaning mechanism includes a hollow rotating disk 8 rotatably connected to the inner wall of the top of the boiler body 1, and a plurality of connecting pipes 9 connected to the hollow rotating disk 8 are installed outside the hollow rotating disk 8, and an annular tube 7 is installed outside the plurality of connecting pipes 9, and a plurality of nozzles and a plurality of scrapers 6 attached to the inner wall of the boiler body 1 are installed outside the annular tube 7, and the bottoms of the plurality of scrapers 6 are respectively fixedly connected to the tops of the plurality of reinforcing plates 17, and the top of the boiler body 1 is rotatably connected to the hollow rotating disk 8 and fixedly connected to the hollow rotating disk 8. A hollow rotating column 11 is provided, a rotating motor is installed on the top of the boiler body 1, a driving wheel 13 is installed on the output end of the rotating motor, a driven wheel 12 meshing with the driving wheel 13 is installed on the outside of the hollow rotating column 11, a cleaning plate 15 fitted with the top of the filter cartridge 16 is installed between two corresponding scrapers 6, a liquid tank 2 is installed on the outside of the boiler body 1, an extraction pump 4 is installed on the top of the liquid tank 2, a water inlet pipe extending into the liquid tank 2 is installed at the inlet of the extraction pump 4, a water outlet pipe is installed at the outlet of the extraction pump 4, one end of the water outlet pipe is connected to the hollow rotating column 11 through a transmission connector 14 and the two are connected to each other.

[0026] The further improved feature of this embodiment is that when the boiler body 1 needs to be cleaned, the rotating motor can be started, and the rotating motor will drive the driving wheel 13 to rotate. Under the cooperation of the driving wheel 13 and the driven wheel 12, the hollow rotating column 11 will rotate. Driven by the hollow rotating column 11, the hollow rotating disk 8 will drive the connecting pipe 9 and the annular pipe 7 to rotate, thereby causing the scraper 6 to rotate, so that the inner wall of the boiler body 1 can be cleaned. When the scraper 6 rotates, it will drive the reinforcing plate 17 and the cleaning plate 15 to rotate. When the reinforcing plate 17 rotates, the outside of the filter cylinder 16 and the inner wall of the connecting cylinder 3 will be cleaned. When the cleaning plate 15 rotates, the top of the filter cylinder 16 can be cleaned. During the cleaning process, the extraction pump 4 will draw the descaling liquid in the liquid tank 2 into the interior of the filter body 1, so that the scale in the boiler can be better cleaned.
