Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 to 7, the household combustion burner with the improved rectifying plate comprises a circular burner 1, an outer ring air mixing cavity 2 is arranged in the burner 1, two mixing cavities 3 communicated with the outer ring air mixing cavity 2 are symmetrically arranged at the bottom of the burner 1, two outer ring ejector pipes 4 are transversely connected to one ends of the two mixing cavities 3, a nozzle 5 facing the air inlet end of the outer ring ejector pipe 4 is installed outside the outer ring ejector pipe 4, a circular rectifying plate 6 is horizontally arranged in the outer ring air mixing cavity 2, the circular rectifying plate 6 is arranged above the two mixing cavities 3 and divides the outer ring air mixing cavity 2 into an upper layer air mixing cavity 201 and a lower layer air mixing cavity 202, an air inlet gap 201 is formed between the inner edge of the circular rectifying plate 6 and the inner cavity wall 21 of the outer ring air mixing cavity 2, an air inlet gap 601 is arranged at one side of the circular rectifying plate 6, and the upper layer air mixing cavity and the lower layer air mixing cavity 202 are communicated with the air inlet gap 7 through the air inlet gap 601, the structure effectively solves the problems that the uniformity of the flame size of the fire cover is poor and the gas mixing is unsatisfactory to cause poor combustion effect when the internal pressure of the furnace end is uneven to cause combustion.
A second air inlet gap 8 (as shown in fig. 4) is formed between the outer edge of the annular rectifying plate 6 and the outer cavity wall 22 of the outer annular air mixing cavity 2, and the upper air mixing cavity 201 and the lower air mixing cavity 20 are communicated through the air inlet notch 601, the air inlet gap 7 and the second air inlet gap 8, so that the inner side and the outer side of the upper air mixing cavity 201 above the annular rectifying plate 6 can uniformly intake air.
The combustor 1 comprises an injection seat 11, a fire cover seat 12 and an outer ring fire dividing cover 13, wherein the fire cover seat 12 is arranged above the injection seat 11, the outer ring fire dividing cover 13 is covered on the fire cover seat 12 to form an outer ring mixed gas cavity 2, a plurality of fire outlet holes 131 are formed in the outer ring fire dividing cover 13, two gas inlets 121 are symmetrically formed in the bottom of the fire cover seat 12, two mixing cavities 3 are concavely arranged in positions of the injection seat 11 corresponding to the two gas inlets 121, and arc-shaped flow guide surfaces 301 are arranged on cavity walls of the mixing cavities 3 corresponding to the gas outlet ends of the outer ring injection pipes 4; arc water conservancy diversion face 301 is drawn the ejector tube 4 blowout back by the outer loop at the gas, flows through in arc water conservancy diversion face 301 channels into outer loop gas mixing chamber 2 fast, makes the mist flow process more smooth and orderly, reduces because the mist hits to straight chamber wall, makes outer loop gas mixing chamber 2 form the turbulent flow, makes the combustion effect unstable.
The fire lid seat 12 bottom between two air inlets 121 is provided with the different interlude 122 of two sections length, and shorter interlude 122 both ends link up with arc water conservancy diversion face 301, and the middle part setting of annular cowling panel 6 is in shorter interlude 122 top, and the both ends of annular cowling panel 6 are then kept off and are established in two air inlets 121 tops, and annular cowling panel 6 corresponds longer interlude 122 department and is provided with air inlet notch 601.
Because the length of outer loop ejector pipe 4 needs to be reserved, therefore the position symmetry that two air inlets 121 set up is not equal but the interval between the head and the tail end, consequently when the gas enters into outer loop gas mixing chamber 2 through mixing chamber 3, because the gas sprays from the one end of mixing chamber 3 toward other end direction, consequently when the gas enters into outer loop gas mixing chamber 2 through mixing chamber 3, the gas can rush to shorter interlude 122 position, lead to the local gas concentration of shorter interlude 122 great, lead to the uniformity of burner's fire lid flame size poor, the burning is unstable, consequently annular cowling panel 6 can transversely flow into the upper strata gas mixing chamber 201 to the gas inlet gap position that corresponds longer interlude 122 (this regional gas concentration is lower) with partial gas mixture of lower floor gas mixing chamber 202, and then pass through the fire hole and discharge the burning from upper strata gas mixing chamber 201 through gas inlet gap 7 (the gas circulation of gas inlet gap 601 is greater than and is greater than the gas circulation of gas inlet gap 601 Air inlet gap 7), the uniformity of burner cap flame size is poor and the gas mixing is unsatisfactory when the uneven burner head internal pressure that leads to burning can effectively be solved to this mode and the not good scheduling problem of combustion effect is caused.
In the above case, the mixed gas may be branched in accordance with the following embodiments:
one embodiment is as follows: a plurality of air inlets 602 are arranged on the annular rectifying plate 6, and the gas flow cross-sectional areas of the air inlets 602 gradually increase from the positions of the annular rectifying plate 6 corresponding to the arc-shaped flow guide surfaces 301 to the two sides (as shown in fig. 5); because the gas concentration and the gas pressure of the lower-layer gas mixing cavity 202 corresponding to the arc-shaped flow guide surface 301 are the maximum, the gas flow rate of the gas inlet gap 7 corresponding to the arc-shaped flow guide surface 301 is the fastest, and the internal pressure of the upper-layer gas mixing cavity 201 can be kept uniform by matching with the gas inlet hole 602 with the structure.
The second embodiment is as follows: the width of the air inlet gap 7 gradually increases from the position of the air inlet gap 7 corresponding to the arc-shaped flow guide surface 301 to the directions of two sides (as shown in fig. 6); the advantageous effects of this embodiment are the same as those of the above embodiment.
The inner cavity wall 21 of the outer ring gas mixing cavity 2 is obliquely arranged from bottom to top towards the outer cavity wall 22 of the outer ring gas mixing cavity 2; the outer cavity wall 22 of outer ring gas mixing chamber 2 is actually to dividing the play fire hole direction slope of fire lid, and when the mist flowed into upper strata gas mixing chamber 201 from lower floor gas mixing chamber 202, the outer cavity wall 22 of the outer ring gas mixing chamber 2 that the slope set up had the guide effect, made near mist can flow the position of going out the fire hole fast, improved mist from the speed that goes out the fire hole and spray.
The outer ring injection pipe 4 and the mixing cavity 3 are symmetrically arranged below the combustor 1 on the same horizontal plane, and the straight tubular outer ring injection pipe 4 is obliquely connected to one end part of the mixing cavity 3; the outer ring draws and penetrates pipe 4 and 3 integral types of mixing chamber to be connected, can reduce the height of combustor, is convenient for assemble the transportation.
A plurality of supporting bosses 23 extend into the outer ring air mixing cavity 2 at equal intervals, lower connecting holes 23-1 are formed in the supporting bosses 23, upper connecting holes 603 are formed in the annular rectifying plate 6 corresponding to the lower connecting holes 23-1, the annular rectifying plate 6 is fixedly arranged in the outer ring air mixing cavity 2 through the upper connecting holes 603 and the lower connecting holes 23-1 through screws A, and the annular rectifying plate 6 can be erected through the supporting bosses 23 and is arranged in the outer ring air mixing cavity 2 in a suspended mode.
The included angle between the two end parts of the annular rectifying plate 6 is alpha, and alpha is more than or equal to 60 degrees and less than or equal to 160 degrees.
The foregoing is a preferred embodiment of the present invention showing and describing the basic principles, main features and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to illustrate the principles of the invention, but rather that various changes and modifications may be made without departing from the spirit and scope of the invention, the scope of which is defined by the appended claims and their equivalents.
