Description
Technical field
The utility model relates to a kind of premixed energy-saving cooking stove head.
Background technology
The burning of combustion gas all needs air-breathing, and the mixed proportion of combustion gas and air and mixability have determined the burning degree of combustion gas.When the mixed proportion of air and combustion gas and mixability are the best, fuel gas buring is the most abundant, burns also the most fully, and the calorific value that produces is also the highest, and the waste gas and the pernicious gas that produce after the burning are also minimum, thereby reach the purpose of efficient, energy-conservation and environmental protection.All kinds of commercial kitchen ranges in the market generally adopt two kinds of empty combustion mixed combustion modes of nature injection type and blowing-type.These two kinds of combustion modes all are rear mixing burnings, be that combustion gas is in the burner hearth internal combustion, mix with air, can't guarantee fully mixing of combustion gas and air, this must cause the part combustion gas to fail fully to burn namely to discharge from flue, the thermal efficiency is lower and flame temperature is lower, has wasted mass energy.
Summary of the invention
The purpose of this utility model provides a kind of premixed energy-saving cooking stove head, in kitchen range, be provided with interior mixed chamber and outer mixed chamber, in interior mixed chamber and outer mixed chamber, combustion gas and air are carried out mixing and for the second time mixing the first time, combustion gas evenly mixes with air, can significantly improve the efficiency of combustion of combustion gas, realize energy-conservation purpose.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of premixed energy-saving cooking stove head, comprise shell body, be arranged in the shell body air inlet pipe and inner chamber cylinder and by the sheet metal group that is no less than two sheet metals and superposes and form; Described inner chamber cylinder bottom opening, its top is provided with base; Described air inlet pipe bottom is fixed on the shell body bottom, its top connects the mixed aerofoil of turbine, the mixed aerofoil of described air inlet pipe and turbine stretches in the inner chamber bucket, and the mixed aerofoil edge of turbine is fixed on the inwall of inner chamber cylinder, has on the mixed aerofoil of turbine and runs through its skewed slot up and down more than one; Described sheet metal is provided with the gap that supplied gas is passed through in the form of a ring between the adjacent metal sheet, described sheet metal group is arranged between shell body and the base; The mixed aerofoil of described inner chamber cylinder inwall, air inlet pipe and turbine forms interior mixed chamber, and inner chamber drum outer wall, shell body and sheet metal group form outer mixed chamber.Combustion gas and air are realized mixing for the first time in interior mixed chamber, then mist enters into outer mixed chamber, and the mixing second time is carried out in mixed chamber outside, mix more even with air through combustion gas in twice mixed gas, therefore the efficiency of combustion of combustion gas is improved, reached energy-conservation purpose, the abundant burning of simultaneously combustion gas also so that after the burning in the waste gas of discharging the content of pernicious gas composition reduce, pollution on the environment is also less.
As further improvement of the utility model, described air inlet pipe is the gradual change type structure, and two ends are cylindric about it, and the centre is round table-like, and the upper end body diameter is less than the diameter of lower end cylinder.Lower end diameter has improved the admission velocity of combustion gas greater than the gradual change type structure air inlet pipe of upper end diameter, is convenient to combustion gas and mixes in interior mixed chamber with air.
As further improvement of the utility model, described skewed slot is evenly distributed on the mixed aerofoil of turbine.Skewed slot is evenly distributed with and is beneficial to gas and enters behind the outer mixed chamber more evenly, and partial pressure is excessive or too small in the unlikely outer mixed chamber.
As further improvement of the utility model, described skewed slot has 12.12 skewed slots are so that air and combustion gas are mixed to get more abundant in the first time.
As further improvement of the utility model, described sheet metal has 18.18 sheet metal is conducive to strengthen for the second time effect of mixing so that the gap width between per two sheet metals is fit to.
As further improvement of the utility model, described shell body is made of two parts up and down, and its upper end is cylindric, and the lower end is round table-like.Up big and down small shell body is fit to the design arrangement of internal structure, and has reduced the space that whole kitchen range takies.
As further improvement of the utility model, described shell body top is provided with flange plate, and described sheet metal group and flange plate are bolted on shell body.With flange plate fixing metal sheet group, shell body and sheet metal group everywhere stressed evenly, not yielding.
Further improve as of the present utility model, described air inlet pipe bottom is provided with internal thread.The air inlet pipe bottom arranges internal thread and is threaded connection with gas pipeline, and is not only easy for installation, and good sealing effect, air tight.
In sum, the beneficial effects of the utility model are: combustion gas and air mix, and the combustion rate of combustion gas is high, and noxious gas emission is few, and pollution on the environment is few, and simple in structure, and is easy to make.
