In the figure: 1. the steam heating device comprises a shell, 2 parts of a heater, 3 parts of a heating pot, 4 parts of a hot water pool, 5 parts of a silencing pipe, 6 parts of an overflow pipe, 7 parts of an exhaust valve, 8 parts of a flue gas outlet, 9 parts of a water storage barrel, 10 parts of a high-pressure pump, 11 parts of a first check valve, 12 parts of a second check valve, 13 parts of a safety valve, 14 parts of a circulating pump, 15 parts of an exhaust fan, 16 parts of a venturi tube, 17 parts of a steam nozzle and 18 parts of a radiator.
Detailed Description
As shown in fig. 1 and 2, the utility model comprises a heating pot 3, a heater 2 arranged at the bottom of the heating pot, a hot water tank 4 arranged above the heating pot, a water storage barrel 9 communicated with the heating pot 3, and a shell 1 surrounding the heater 2, the heating pot 3, the hot water tank 4 and the water storage barrel 9. The heater 2 is a gas heater. A sealing cover is arranged at the top of the heating pot 3, a steam pipe for communicating the heating pot 3 with the hot water pool 4 and two safety valves 13 are arranged on the sealing cover, and the middle part of the steam pipe is connected with a first check valve 11; the top end of the steam pipe extends into the hot water tank 4 and then is connected with a steam nozzle 17, and the top of the steam nozzle 17 is connected with a venturi tube 16. The venturi tube 16 is externally sleeved with a silencing tube 5, and the silencing tube 5 is made of a plurality of layers of stainless steel wire meshes. The bottom end of the silencing pipe 5 is connected with the bottom plate of the hot water pool 4, and the top end of the silencing pipe 5 extends to the top plate of the hot water pool 4.
The hot water tank 4 is connected with a radiator 18 through a circulating pipeline, a circulating pump 14 is arranged on the circulating pipeline, an overflow pipe 6 extending out of the shell is arranged at the top of the hot water tank 4, and an exhaust valve 7 is arranged at the top end of the overflow pipe 6. The top of the water storage barrel 9 is provided with an open water inlet which leads to the outside of the shell, and the water outlet of the overflow pipe 6 is communicated with the open water inlet of the water storage barrel 9. The bottom of the water storage barrel 9 is connected with a high-pressure pump 10 through a pipeline, and a second check valve 12 is arranged on the pipeline between the high-pressure pump 10 and the heating pot 3. The top of the shell 1 is provided with a smoke outlet 8, and the smoke outlet 8 is provided with an exhaust fan 15.
The utility model discloses during the application, add one in heating pot 3 and half water, utilize heater 2 for heating pot 3 heats, steam that produces after the water is boiled flows to steam jet through first check valve when the steam, and steam gets into hot-water pond 4 after, mixes the production hot water at the water in venturi 16 and the hot-water pond. When the water temperature reaches the specified temperature, the water is sent to the radiator 18 by the circulation pump 14. The first check valve 11 is added to prevent the water in the hot water tank from flowing into the heating pot.
Since the venturi effect generates a pressure difference, water continuously flows into the venturi tube 16 and is mixed with high temperature steam, and noise is generated while the water and the steam are mixed, the silencer duct 5 is installed outside the venturi tube to reduce noise.
