Abstract

Disclosed is a medium-pressure furnace deep-rotation type burner, which is composed of a concave type furnace header and a concave type furnace cover. The utility model has important points that the external wall of the cavity body of the furnace header, which is much higher than an inner side, shows concave type; the ventilation inner tube disposed on the binding site of an air inlet pipe and the cavity body of the furnace header is a directly inserted pipe or an inclined type pipe; the lower concave part of the concave type furnace cover is an inclined wall or a vertical wall, a plurality of inclined holes or inclined grooves are uniformly disposed in the inclined holes or the inclined grooves. The utility model has simple structure, uniform air distribution, abundant burning, fierce flame, large impulsive force, high temperature, fast heating, high heat efficiency and remarkable energy saving, fuel gas can be accelerated to be contracted by using the utility model.

Description

Medium pressure furnace deep rotary burner

The utility model belongs to the household gas utensils technology, relates to a kind of medium pressure furnace deep rotary burner of fast energy-saving type.

The existing medium pressure furnace burner overwhelming majority is a directly-firing or flat rotating, because their firepower relatively disperses, flame is fierce inadequately, and the thermal efficiency is low, and consumption gas is many.Several novel burners of exploitation are arranged in the recent period, and it is little to have plenty of fumarole, and firepower is little, easily stops up; Have plenty of complex structure, manufacture the cost height, this all applies to it and brings certain unfavorable factor.

The purpose of this utility model provides a kind of quick, energy-conservation medium pressure furnace deep rotary burner, this burner can make combustion gas quicken poly-revolving, and air distribution is even, sufficient combustion, flame is fierce, impulse force is big, temperature height, thermal efficiency height, energy-saving effect is remarkable, and spray orifice is difficult for stopping up, and is simple in structure, overcome the drawback of more recent novel burners.

The utility model is realized with following scheme: it is made up of deep concave type burner and deep concave type bell.The deep concave type burner is formed by connecting screw, air inlet pipe and burner cavity outward; On the bottom surface of burner cavity fixing threaded hole is arranged.Its main points are that the outer wall of burner cavity is much higher than inwall, are deep concave type; Guan Weizhi goes into type pipeline or oblique type pipeline in the ventilation of air inlet pipe and burner cavity binding site; Deep concave type bell lower concave part is steeper skew wall or straight wall, has equally distributed inclined hole or skewed slot on skew wall or the straight wall.

Below in conjunction with accompanying drawing the utility model is elaborated:

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

Fig. 2 is a left view of the present utility model.

Fig. 3 is the front view of pipe furnace head in the oblique type ventilation.

Fig. 4 is the left view of straight wall type bell.

Fig. 5 is the upward view of skew wall formula bell.

Fig. 6 is the upward view of burner cavity.

According to Fig. 1, shown in Figure 2: medium pressure furnace deep rotary burner is made up of deep concave type burner 1 and deep concave type bell 2, and wherein deep concave type burner 1 is formed by connecting screw 3, air inlet pipe 4 and burner cavity 5 outward; Fixing threaded hole 6 is arranged, as Fig. 2, shown in Figure 6 on the bottom surface of burner cavity 5; The outer wall 7 of burner cavity 5 is much higher than inwall 8, is deep concave type, as shown in Figure 2; Air inlet pipe 4 is gone into type pipeline 9 or oblique type pipeline 10 with the interior Guan Weizhi of the ventilation of burner cavity 5 binding sites, as Fig. 1, shown in Figure 3; Deep concave type bell 2 lower concave parts are steeper skew wall 11 or straight wall 12, as Fig. 2, shown in Figure 4; Have equally distributed ventilation inclined hole 13 or skewed slot 14 on skew wall 11 or the straight wall 12, as Fig. 4, shown in Figure 5.

During use, this burner is connected with the jet Luo Zui of medium pressure furnace switch assembly by connecting screw 3 outward, and is fixed on the stone or metal plate for standing a stove on as a precaution against fire of medium pressure furnace by the fixing threaded hole 8 of burner cavity 5 bottom surfaces.During ventilation, combustion gas is chewed middle ejection from the jet spiral shell of switch assembly, air inlet pipe 4 through burner, directly go into type pipeline 9 or oblique type pipeline 10 enters burner cavity 5, and after inclined hole 13 on bell skew wall 11 or the straight wall 12 or skewed slot 14 ejections, form the poly-swingfire flame of a powerful and sufficient combustion when lighting, firepower is concentrated, the flame temperature height, particularly oblique type pipeline 10 quickened combustion gas in burner cavity 5 rotation and in inclined hole 13 or the skewed slot 14 impulse force during ejection, make air distribution more even, the firepower of rotation fire is more fierce, and it is more abundant to burn, the thermal efficiency is higher, so medium pressure furnace deep rotary burner has firing rate fast, the characteristics that energy-saving effect is high.

The utility model modern design, simple in structure, with low cost, flame is fierce, and impulse force is big, the temperature height, heating is fast, and energy-saving effect is very remarkable, and it can replace present general medium pressure furnace burner and be widely used in hotel, restaurant, dining room, industrial baking processing and enter family's use.
