Description

The coal-gas range head inlet duct

The utility model relates to a kind of gas burner burner, particularly relates to a kind of coal-gas range head inlet duct.

As Fig. 1, shown in Figure 2, general coal-gas range head is to be provided with in a furnace head base 1 inside to be circular and an opening annular groove 101 up, and at this furnace head base 1 inner circular hole 102 that forms, these circular hole 102 central authorities have protruded out pipe 103 in again, should form endoporus 104 in interior pipe 103 inside, one stove top 2 can be located at furnace head base 1 and annular groove 101 tops, a central lid 3 is installed at these endoporus 104 tops, and furnace head base 1 side extends an outer shroud snorkel 4 along the tangential direction of annular groove 101, these outer shroud snorkel 4 inboards are provided with ring snorkel 5 in again, and make outer shroud snorkel 4 wherein an end can be linked to furnace head base 1 bottom, and utilize a blowhole 401 to be connected on annular groove 101 groove bottom 105, borrow said structure, when coal gas by outside, interior ring snorkel 4, during 5 input furnace head bases, 1 inside, can jet out flames by the fire output hole on stove top 2 and the central lid 3.

Really, utilize above-mentioned furnace head base 1 can reach the application target of expection, but, when coal gas is imported annular groove 101 inside by outer shroud snorkel 4 desires, can be bending because of outer shroud snorkel 4, and at turning point formation flow-disturbing, so that there is the crushing situation to produce, and because of the blowhole 401 of outer shroud snorkel 4 is connected on annular groove 101 groove bottom 105, then when coal gas after blowhole 401 is input into annular groove 101 inside, can flow to along annular groove 101 hoops again each position of annular groove 101, then more the gas pressure near blowhole 401 is bigger, and more is that to be away from the gas pressure of blowhole 401 littler, thus, flame on the then more close stove top 2 of this blowhole 401 is big (big fire), and more away from the flame on the stove top 2 of blowhole 401 less (little fire), can cause flame status situation pockety.

Moreover, have different primary air requirements at different types of coal gas (as barreled coal gas, natural gas, town gas etc.), and general burner there is not the structure of adjustable primary air requirement.

The purpose of this utility model is to provide a kind of gas that makes to be sprayed by the fire output hole of stove top equably, to reach the uniform coal-gas range head inlet duct of the state of firing.

The utility model coal-gas range head inlet duct, be to be provided with an annular groove that is circular in a furnace head base inside, and central authorities are provided with an endoporus, this furnace head base side is provided with ring snorkel in an outer shroud snorkel and again, in being somebody's turn to do, the outer shroud snorkel axially be symmetrical in furnace head base radially, and just be symmetrical in the center of furnace head base, in being somebody's turn to do, the outer shroud snorkel is stagger setting and interval predetermined angular, the annular groove groove bottom of this furnace head base is skewed, and by a deep end gradually when a shallow end tilt to be extended, reduce the degree of depth of annular groove gradually, and make this outer shroud snorkel just be symmetrical in this deep end, one stove top can be located at furnace head base and annular groove top, a central lid is installed at this endoporus top, and work as coal gas by outside the furnace head base side, when interior ring snorkel input furnace head base is inner, can jet out flames by the fire output hole on stove top and the central lid, and reach the purpose of burner burning, in addition, this furnace head base side convexes with flange, this flange inside is provided with an outer shroud blowhole, can be for outer shroud snorkel installing location, the space that interior ring snorkel is then tilted to be caused by the annular groove groove bottom, and extend to the central authorities of furnace head base by the outside, to reach the purpose of independent runner, in being somebody's turn to do, the outer shroud snorkel respectively comprises an adapter, one nozzle carrier and an adjustment rack, the adapter of this outer shroud snorkel can be socketed in the outer shroud blowhole, and the adapter of interior ring snorkel can directly stretch to and sets the position in the endoporus of furnace head base, be provided with an adjustable adjustment rack between this nozzle carrier and the adapter, utilize the adjustment action of adjustment rack, can reach the purpose of adjusting the primary air requirement.
