Abstract

The utility model relates to a gap air vent stove head which is used for fuel gas or fuel oil cookers provided with a stove head. The existing swirling flow gap stove head is additionally provided with an outer shutter outside to take secondary air and reduce carbon monoxide. The utility model is composed of a burner (1), the outer shutter (2) and an inner shutter (3), wherein the outer shutter is a 12-angle external circular cone of which the conical cambered surface is provided with 12 gap ports; 24 gap ports are uniformly distributed on the inner shutter sheathed in the outer shutter, every other gap port of the inner shutter is matched with the gap port of the outer shutter. The inner shutter and the outer shutter are closed in a D direction, are provided with secondary air gap ports in an F direction and provided with fuel gas nozzles in an E direction and a K direction. The gap air vent stove head is provided with a small fire head; when the swirling flow flame burned by the small fire head generates flow speeds and a temperature difference between inside and outside to form a negative pressure, air is ejected from the F outside to inside. Energy can be saved by 10%.

Description

Gap air vent burner

The utility model relates to fuel oil, the parts of gas burning range, burner.

Have only an air air inlet in the burner of the clearance type eddy flow stove circle at present, the air port is big, and temperature reduces, and the air port is too small, the carbon monoxide content height.

The purpose of this utility model provides fuel oil, and the burner of gas stove is taked secondary air, cuts down the consumption of energy and the content of carbon monoxide, improves the thermal efficiency.

The purpose of this utility model is to realize like this, it is blind window (2) outside outside the burner of existing slit spiral-flow type stove, setting up, it is by burner (1), interior blind window (3) constitutes, its feature is that also outer blind window (2) is 12 jiaos of circumscribed circle cones, its circumscribed circle cambered surface F position, be provided with air port, 12 slits, the taper seat of blind window (3) in the cover in its inner cone, the conical surface of interior blind window, uniform 24 slit aperture, air port, slit with outer blind window (2), every interval cooperates, and E has design slit combustion vapour spout at interval to the position between the inside and outside blind window, D seals to the position, the big end rivet welding one of inside and outside blind window, small end and burner (1) socket flows to each bar slit spout when combustion vapour enters burner (1), produce swirl flame, inner eddy flow speed height, internal-external temperature difference is big, produces negative pressure, air sprays into from the air port, slit of outer blind window (2), forms 24 flame envelopes and comes together in main air port.

Owing to take such scheme, Gap air vent burner is a combustion vapour spout, establishes the air port, slit again, empty vapour and combustion gas at interval, proportioning is fit to, synchronous preheating time is long, the temperature of flame envelope is than internal flame height, and is higher than about 300 ° of present furnace temperature.

Below in conjunction with drawings and Examples, the utility model is further specified.

Fig. 1 is a plan view of the present utility model

Fig. 2 is that A-A analyses and observe, and B-B is the cutaway view of Fig. 2

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1, Fig. 2, shown in B-B analyses and observe, outer blind window (2) is 12 jiaos of circumscribed circle cones, its the external circular arc conical surface is offered air port, 12 slits, its internal diameter inner cone cambered surface, blind window (3) in the interior cover, interior blind window (3) conical surface is offered 24 slit aperture, one at every interval cooperates with the air port, circular arc conical surface slit of outer blind window (2), E between the inside and outside blind window has design combustion vapour slit spout at interval to the position, D seals to the position, the big end rivet welding one of inside and outside blind window, small end respectively with the interior external diameter socket of burner (1), the tubulose position of burner (1) is cast with two back-up blocks, and inside and outside blind window is made by the 0.5mm corrosion resistant plate.

According to such scheme, the utility model is made of cover in the bull Gap air vent burner, outer blind window (two) is a hexagonal circumscribed circle cone, its lower end cylindrical tube shape, the middle-end transverse weld burner (one) of tubulose it by stator (4), quadruplet Luo bolt (5) is fixed on the back-up block of burner (1) side by side, interior its lower end of blind window (three) of cover is sealed by end cap (6) in the outer blind window (two), upper end rivet welding one, middle-end F is to offering air port, six slits, E between the inside and outside blind window is to design combustion steam ports spout is at interval arranged, D is to being enclosed in Fig. 3, among another embodiment among Fig. 4, Gap air vent burner, by 12 combustion air ports, 12 slits of vapour slit spout (k) (F) state at interval, D is to the closed at both ends of position between the inside and outside blind window, and the g of Fig. 3 is to combustion vapour slit spout, be on an axis, a design arranged at interval by two semicircular slit aperture.

The utility model adopts the principle of oxyacetylene blowpipe, carries out secondary air, and combustion vapour, empty automobile fitting can be used for industry, civilian than being fit to, and the burner of stove and accessory cuts down the consumption of energy and carbon monoxide, improves the thermal efficiency, has a extensive future.
