Abstract
Provided is a ratio adjusting device specially used for a direct-fired gas burner of a textile tentering setting machine. The device is used for adjusting the air-gas ratio for combustion, and synchronically keeping a ratio coefficient in an adjustable range of load so as to guarantee combustion efficiency. In a specific environment of the textile stretching machine, a butterfly valve of an air inlet is designed as circle-shaped, corresponding to a circular butterfly valve of an air outlet. The butterfly valve of the air inlet and the butterfly valve of the air outlet are connected via a pull rod therebetween, and driven by a servo motor. The butterfly valve of the air inlet is in a linear proportion relation with the butterfly valve of the air outlet.
Description
Technical field
The present invention belongs to mechanical structure field for the direct-fired gas burner special-purpose air combustion gas ratio adjusting yoke of weaving typing mechanism.
Background technology
Burning needs oxygen, so gas burner will fully burn, and must make combustion gas and air mix after-combustion according to a certain percentage.The burner that ratio is regulated requires in whole controllable burden scope, all to reach certain efficiency of combustion.We regulate the size of combustion gas air inflow usually, adjust the output load of burner, and are synchronous in this, and intake will adjust accordingly.Universal gas burner is because receive the slow influence of air intake flow velocity, and air-admitting surface is bigger, can only use the rectangle butterfly valve; And mostly the gas pipeline cross section is circular; Therefore when rotating same angle between them, there is non-linear relation, must uses fan-shaped guiding mechanism; (sector disk is from 0 ° to 90 ° for correction error between the two; Set some points, each point can be adjusted fan-shaped diameter, forms an arc on the sector disk surface.We come modified spatial combustion ratio through the adjustment radian).
Mostly the employed direct-fired burner of weaving stentering forming unit is small-sized forced-air blast burner, and the volume of burner is very little, is unfavorable for complicated fan-shaped mechanism installation.And the debugging of this mechanism also is quite complicated, and we must let burner piecemeal change from the minimum load to the peak load, and the composition of the measurement flue gas that does not stop is revised the angle ratio of air inlet and air inlet, can't accomplish real linear regulation.
Summary of the invention
This invention is exclusively used on the direct-fired gas burner of weaving framing shaping machine, makes full use of the characteristics of the inner high negative pressure of textile setting machine, changes the air inlet shape.High negative pressure increases more than 2 times the burner intake velocity, and making air-admitting surface be designed to circle becomes possibility.
Concrete technical scheme of the present invention is following:
After the butterfly valve at air inlet and air inlet two places all is circle, become the linear relationship of fixed proportion between them.Use a servo motor,, drive two butterfly valves simultaneously and rotate, can not change regardless of the air-fuel ratio numerical value that is which point with equal angular through drag link mechanism.Then, we are provided with one " revising the air intake valve " on circular air intake butterfly valve limit, and the aperture of this valve and gas electromagnetic valve is done corresponding adjustment.
We fix on maximum position to the output load point when the debugging burner.This moment, combustion gas air inlet disk valve and air air intake butterfly valve all reached maximum 90 ° (standard-sized sheet); Strengthen the aperture of gas electromagnetic valve then, increase the combustion gas air inflow, (the actual demand value can be less than the burner design maximum to reach the user's actual need value; And receive the influence of combustion gas admission pressure; Flow can change, thus need adjustment).Then, measure gained through flue gas analyzer, the aperture that adjustment " is revised the air intake valve " is up to optimum value.The air-fuel ratio numerical value of this moment is best, and because two butterfly valves of air inlet and air inlet keep the linear ratio relation, the air-fuel ratio numerical value of all angles is all constant, is same value.
Fig. 1 is an air-fuel ratio adjusting screw(rod) structure.
