Description
Technical field
The present invention relates to a kind of cyclone fire cover of burner of gas stove or range.
Background technology
The eddy flow ring of the spiral-flow type burner for gas stove of Chu Shouing in the market, hole, eddy flow slit on it is to have the slit on conical surface tegmental wall, because it is straightsided shape or pointed shape that the slit adds man-hour its two ends, big to the fuel gas flow resistance, combustion flame often clings the gap joints burning, the eddy flow effect is relatively poor, though carbon monoxide content meets national standard in the burnt gas, but do not reach lower index yet, also there is above-mentioned weak point in the compression ring that goes out in Chinese patent application number 86207821.0 slot hole vortex burners.Though the eddy flow ring of application number 97238801.X burner of gas stove or range has been done improvement, the effect of carbon monoxide content in the bigger reduction waste gas has been arranged, still have further improvement to improve the possibility of effect.
Summary of the invention
The cyclone fire cover that radiation loss is little, efficiency of combustion is higher, attractive in appearance when the purpose of this invention is to provide a kind of combustion gas eddy flow better effects if, burning use.
The present invention realizes with following mode: there is emptying aperture at the cyclone fire cover middle part, is evenly equipped with strip eddy flow gap joints on the cyclone fire cover, and gap joints tilts to capping.Cyclone fire cover comprises that bezel ring,, oblique cone lid and support ring connect into whole formation continuously, and the round circlewise oblique cone that is distributed on thin-walled of strip eddy flow gap joints covers, and gap joints cracks along the capping width of oblique cone lid, and the two ends of the gap length direction of gap joints are uncovered.Described oblique cone covers the end cap wall and connects bezel ring,, and the lower end tegmental wall connects support ring, and bezel ring, and support ring support the oblique cone lid and be tiltedly lid of projection.Gap joints is 55 ° to 65 ° angles to the inclined angle alpha that capping tilts.The wide b of the seam of gap joints is 0.5 to 1.1 millimeter.Oblique cone lid cone angle beta be 90 ° to hexagonal angle.The optimum α angle of gap joints is 60 ° of angles.It is hexagonal angle that oblique cone covers optimum cone angle beta.Be sewn on when using different combustion gas, gap joints gap width b is 0.6,0.7 or 1.0 millimeter than the figure of merit.
The present invention is simple in structure, makes easily, use reliably, and the eddy flow better effects if, radiation loss reduces, the cyclone fire cover long service life, attractive in appearance handy, carbon monoxide content is lower behind the fuel gas buring.Be suitable for the cyclone fire cover of making burner for gas stove.It is a kind of cyclone fire cover with environment-friendly type characteristic.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
Present embodiment is selected following more excellent parameter value for use, and the slotted wall of gap joints 5 is 60 ° of angles to the inclined angle alpha of tangential plane (the setting plane of the conical surface tangent to periphery direction) inclination at place capping place, and the cone angle of oblique cone lid 1 is a hexagonal angle.When combustion gas kind difference,, it is 0.6 or 0.7 or 1.0 millimeter because the calorific capacity difference can be selected gap width b value for use as with liquefied gas, coal gas, natural gas, biogas.
Cyclone fire cover is individual whole the product that is linked into an integrated entity continuously by bezel ring, 2, oblique cone lid 1 and support ring 3.Oblique cone lid 1 is the oblique lid of a projection, and the upper end connects bezel ring, 2, and the lower end connects support ring 3.Bezel ring, 1 is the crotch annulus, and the oblique lid of its upper end planar circular connection bump is mounted on duration and degree of heating (burner body that claims burner again) lateral wall when annulus uses under the outside.Support ring 3 is annulus of a setting, and upper surface and scalene cone 1 bonding pad are crotch shape, and the annulus of erectting during use is placed on the hole wall step below the endoporus of duration and degree of heating.Tiltedly cover in the projection of oblique cone lid 1 and to be evenly distributed with strip eddy flow gap joints 5 circlewise, gap joints cracks along the capping width of oblique cone lid 1, the two ends of the gap length direction of gap joints 5 are uncovered, and gap joints tilts to capping, and the slit of present embodiment is sewed with 21.Cyclone fire cover copper material manufacturing, cyclone fire cover wall thickness are 2 millimeters.This cyclone fire cover is contained in when using on the height of anger, and the thermal efficiency reaches 63%, and carbon monoxide content is better than national standard greatly＜0.025% in the combustion tail gas.The emptying aperture 4 at cyclone fire cover middle part is to replenish during for burning to enter the through hole that auxiliary air is used.
Slot hole vortex burner originally, its gap joints is opened on the circular cone capping, remain silent in the length direction two ends in slit, link to each other with the circular cone capping, when gas-flow passed through the slit, the termination of remaining silent in the slit can produce resistance, and was not too unimpeded in this two ends fuel gas flow, make fuel gas buring influenced fully, cause in the burnt gas carbon monoxide content higher.Though in the national Specification scope, but still have the possibility that further reduces.In addition, flame is often hung in the slit two ends and is stayed during burning, flame base also can take place just be bonded at gap joints outlet burning.The cyclone fire cover temperature is raise, cause the stove temperature to raise, the lost loss of heat is bigger.For solving the factor that these two influences further improve combustion position, the oblique cone lid 1 of slot 5 of will cracking is modified into the oblique lid of projection, the two ends of gap joints 5 is uncovered, two ends non-resistance when making gas-flow cross the slit, fuel gas flow is unobstructed, the combustion gas oblique outflow of taking advantage of a situation from the slit, produce the eddy flow stratiform eddy flow combustion gas that makes progress, stratiform swirl flame eddy flow is better during burning, combustion efficiency is good, and burning stratiform flame lower end breaks away from gap joints and fire lid capping fully, and flame does not have at two ends, slit extension and stays during burning, and tiltedly lid is to forward spin flow from projection, and flame does not directly heat with bezel ring, 2 and support ring 3.Fire lid and stove temperature rise are reduced, and radiation loss reduces, thereby further improves the thermal efficiency and reduce carbon monoxide content in the combustion gas waste gas, prolong the cyclone fire cover life-span again, cyclone fire cover cleaning, bright and clean does not produce and burns black situation, is a kind of cyclone fire cover with environment-friendly type characteristic.
