Abstract

The utility model belongs to the technical field of flame singeing, comprising a burning mouth lower body with sealing connection and a burning mouth upper body with the sealing connection. A premixed gas inlet pipe and a middle hole plate are arranged in the burning mouth lower body; a trapezoidal ribbed slab, a wedge plate and a lower burning chamber wall are arranged in the burning mouth upper body; an arcuate upper burning chamber wall is arranged above the lower burning chamber wall. When used, flame high-temperature zone is in the semi-enclosed upper burning chamber. The heat loss is less, the temperature gradient is small, and the flame temperature is high.

Description

Semi-closed reflective burning mouth of pile-burner

The utility model belongs to the flame equipment technical field of singing, and is installed on the gassing frame, to singing of all kinds of fabric finishing operations.

Burner is the critical component of gassing frame, and it directly affects the quality of singing of flame temperature, efficiency of combustion, energy resource consumption and the fabric of gassing frame.The patent No. is 85201388 " spiral spray formula gassing frame burner ", comprise burner chamber down, last burner chamber, first combustion chamber, second combustion chamber and nozzle body conduit, one jet feather key is housed in the nozzle body conduit, though this burner is in flame temperature, the quality of singing progression, reach advanced world standards in main economic and technical norms aspect such as energy resource consumption, but its shortcoming is when work, flame directly erupts in air, fabric passes through from the top of flame, thereby can only some heat energy be utilized, the heat energy of another part is dispersed in the air and slatterns, also because the thermograde that on each cross section, produced of combustion-gas flow, can directly affect the raising of the quality of singing.

The purpose of this utility model is that design a kind ofly can improve the thermal efficiency, cut down the consumption of energy, and can improve the gassing frame burner of the quality of singing again.

This gassing frame burner comprises the burner lower body, the burner upper body that is tightly connected with the burner lower body, in the inner chamber of burner lower body, be equipped with and give mixed gas inlet pipe, give mixing to have on the gas inlet pipe to give and mix gas and portal, orifice plate in the middle of in the upper end of burner lower body, being placed with on the edge, have inclined hole on the middle orifice plate, it is characterized in that being equipped with in the inner chamber of burner upper body the trapezoidal gusset on the orifice plate in the middle of being fixed on, the bottom of trapezoidal gusset has the gusset hole, on the inwall of burner upper body, place the wedge that two rows and trapezoidal gusset form two slits, article two, the extended line of slit intersects in lower combustion chamber, fixed placement has lower combustion chamber's wall on the upper end of every row's wedge, is provided with the arc upper combustion chamber wall that constitutes upper combustion chamber with the upper end of lower combustion chamber wall above lower combustion chamber's wall.

The course of work of this gassing frame burner is, give and mix gas and mix giving on the gas inlet pipe and mix gas and portal and enter intracoelomic cavity under the burner through giving, inclined hole on middle orifice plate enters intracoelomic cavity on the burner again, after passing the gusset hole, by two slot injection in lower combustion chamber, since give mix that gas runs foul of each other in lower combustion chamber and with the collision of lower combustion chamber's wall, take fire, combustion-gas flow is sprayed by lower combustion chamber, meet chamber wall and stop, reflex to again and continue in the upper combustion chamber and fully burning, form the flame high-temperature region, the fabric of desiring to singe passes in upper combustion chamber, realizes singing to fabric.Because the flame high-temperature region is in semi-enclosed upper combustion chamber, thermal loss is few, and thermograde is little, the flame temperature height, thus the thermal efficiency improved, reduced energy consumption, compare with spiral spray formula gassing frame burner, energy consumption reduces 15-20%, and the progression of singing improves 0.5 grade.

Accompanying drawing shows the embodiment of semiclosed reflective gassing frame burner, wherein

Fig. 1 is the front view of embodiment;

Fig. 2 is the A-A cutaway view of Fig. 1.

In the present embodiment, semiclosed reflective gassing frame burner comprises burner lower body (12), the burner upper body (9) that is tightly connected by sealing strip (16) and bolt (17) with burner lower body (12), in the inner chamber (14) of burner lower body (12), be equipped with and give mixed gas inlet pipe (11), give and have three rows on the mixed gas inlet pipe (11) and give and mix gas portal (13), in the upper end of burner lower body (12) along on be placed with in the middle of orifice plate (15), have four row's centroclinal inclined holes (10) on the middle orifice plate (15) symmetrically, trapezoidal gusset (20) on the orifice plate (15) in the middle of being fixed on is housed in the inner chamber (18) of burner upper body (9), the bottom of trapezoidal gusset (20) has gusset hole (19), one inner convex platform (27) is arranged on the inwall of burner upper body (9), place the wedge (8) that two rows and trapezoidal gusset (20) form two slits (7) on it, article two, the extended line of slit (7) intersects in lower combustion chamber (6), its angle is 60 ° ± 2 °, the width of slit (7) is 0.8 ± 0.1mm, be placed with gasket seal (21) and lower combustion chamber's wall (5) on the upper end of every row's wedge (8), burner upper body (9) is provided with the fixedly pressing plate (22) of lower combustion chamber's wall (5), pressing plate (22) is fixed together by bolt and burner upper body (9), the inner surface of lower combustion chamber's wall (5) is provided with inner convex platform (24) and following inner convex platform (23), increase and give the collision frequency that mixes gas, be convenient to burning, be provided with the arc upper combustion chamber wall (1) that constitutes upper combustion chamber (4) with the upper end of lower combustion chamber's wall (5) in the top of lower combustion chamber's wall (5), upper combustion chamber's wall (1) comprises flame retardant coating (3) and the metal shell (2) that is connected as a single entity with flame retardant coating (3), metal shell (2) is provided with terminal pad (25), so that be connected with the gassing frame frame.
