Specific embodiment
Referring to figs. 1 to 4, the present invention is a kind of secondary air gas-operated thermal bath facility, including burning with interior cavity
Room 1, one end of combustion chamber 1 are connected with a front tube 3, and the port of front tube 3 is provided with an air door 5, there is a spray nozzle device 4 installation
In on air door 5, the jet hole of spray nozzle device 4 is located in front tube 3, and the input terminal of spray nozzle device 4 is connect with gas inlet pipe 6,
The surface of combustion chamber 1 is additionally provided with the burner being fixedly connected with combustion chamber 1 on combustion chamber 1 at least provided with an aperture 11
2, burner 2 is equipped with a through-hole communicated with aperture 11, and burner 2, which is additionally provided with, to be communicated with the through-hole of burner 2 and close to small
The air inlet 21 in hole 11.
A kind of gas-operated thermal bath facility of secondary air, by the nozzle of the aperture 11 of combustion chamber 1, being additionally arranged a combustion
Burner 2, according to jet current principle, the negative pressure formed using the combustion gas that aperture 11 sprays increases the channel inlet mouth 21 of secondary air,
More air are introduced, in the new air that burner 2 introduces, make mixed gas in burner 2 that laminar flow occur, in burner 2
Exit is fully burned, and can not only eliminate carbon distribution, can also save the quantity of combustion gas.
It is further used as the improvement of technical solution of the present invention, and the outside of air door 5 is provided with a door regulating plate 51, works as nozzle
The combustion gas that device 4 sprays forms jet stream in front tube 3, and front tube generates negative pressure, and door regulating plate 51 is adjustable to make the external world
Air enter front tube 3 and make air and combustion gas mixing.
It is further used as the improvement of technical solution of the present invention, when the quantity of the aperture on the surface of combustion chamber 1 is two or more
When, aperture 11 is equidistantly positioned the surface in combustion chamber 1.Using the aperture 11 being equidistantly positioned, such combustion heating is more equal
It is even, it can effectively improve the quality of welding.
By further to the experiment of burner, it is contemplated that the versatility of public skill and material, it is determined that optimal
Technical solution, combustion chamber 1 and burner 2 are designed to cylindrical shape.Burner 2 can be Venturi tube, and can by into
The adjusting in air port makes the better effect of heating, but such manufacturing cost is higher, is not suitable for the production with factory.Nozzle dress
The nozzle opening diameter for setting 4 is 2.5mm, and a height of 50mm of burner 2, the internal diameter of burner 2 is 32mm, the internal diameter of combustion chamber 1
It for 42mm, is fixed on combustion chamber 1 between burner 2 and combustion chamber 1 by spot welding, welds a height of 2mm, in such condition
Under, the combustion gas of burner 2 can be fully burned, and fuel value can reach maximum, and in this way will not be in the cylinder of heating
Carbon distribution is generated on the outer wall of body.
