The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Example 1
The present embodiment provides an infrared metallic honeycomb body which is an annular layered structure formed by winding a metal strip 1, and between adjacent two layers of the coils, honeycomb holes 2 for gas flow are formed, as shown in fig. 1. When the infrared metal honeycomb body is applied to an infrared metal burner, mixed gas of fuel gas and air enters from the gas inlet of the honeycomb holes 2 and flows axially upwards along the honeycomb holes 2, and the mixed gas is ignited and combusted in the honeycomb holes 2, so that the mixed gas has a slow flow velocity and has a risk of backfire; and the heat reflected by the pot bottom enters the combustor through the honeycomb holes 2, so that the internal temperature and the tempering probability of the combustor are improved, and potential safety hazards exist.
In order to solve the above problems, the infrared metal honeycomb of the present embodiment further includes a plurality of blocking members 3, each blocking member 3 being connected to each layer of the coils for blocking heat radiation from the outlet direction of the honeycomb holes 2; each barrier component 3 also forms a gas flow channel 31 with the adjacent coiled coil for conveying gas to the honeycomb holes 2; the cross-sectional area of the airflow passage 31 is smaller than the cross-sectional area of the honeycomb holes 2 in the intake direction.
Because every blocks subassembly 3 and is connected with every layer of coiling circle and can reflect the gas outlet of honeycomb holes 2 with the heat radiation from honeycomb holes 2 gas outlet direction back, so can avoid inside the heat radiation enters into the combustor, and then reduce the inside temperature of combustor, reduce the probability of tempering.
Also because each baffle member 3 also forms with the adjacent coil a gas flow channel 31 for delivering gas to the honeycomb cells 2; in the air inlet direction, the area of the cross section of the airflow channel 31 is smaller than that of the cross section of the honeycomb holes 2, so that the flow velocity of the mixed gas is increased after the mixed gas passes through the airflow channel 31, the tempering probability is effectively reduced, and the problem that the existing infrared metal honeycomb body has high tempering probability is solved.
Further, the blocking component 3 is arranged at the air inlet of the honeycomb hole 2; the mixed gas is accelerated after passing through the gas flow passage 31 and then enters the honeycomb holes 2, and moves in the honeycomb holes 2 at a faster flow rate, so that the possibility of backfire is further reduced.
Further, the barrier member 3 includes a reflection portion; the reflecting surface of the reflecting part faces the direction of the air outlets of the honeycomb holes 2 and is used for reflecting heat radiation from the direction of the air outlets of the honeycomb holes 2; the reflecting part can reflect heat from the air outlets of the honeycomb holes 2 back to the air outlets, so that part of heat is effectively prevented from entering the combustor, and the temperature inside the combustor is reduced; the heat emitted by the reflecting part heats the bottom of the pan, so that the utilization rate of the heat is improved. The reflective portion is a metal, such as a foil strip.
Further, since the infrared metal honeycomb body of the present embodiment is an annular layered structure formed by winding the metal strips 1, in order to reduce the production cost and further improve the production efficiency, the edge of each coil which is adjacent to the cell holes 2 to be ported is sequentially turned up toward the adjacent coil to form the barrier assembly 3.
The blocking component 3 is positioned at the air inlet of the honeycomb hole 2, and because the blocking component 3 is formed by flanging the metal belt 1, additional parts in the infrared metal honeycomb body are avoided, and the production cost is further reduced. Still because the stop component 3 is the reason of metal material, so stop component 3 itself at this moment just has the function of reflection heat, and it can reflect the heat that comes from the bottom of a boiler back to the bottom of a boiler, reduces the inside temperature of combustor, reduces the probability of tempering.
In the specific production process, the metal belt 1 needs to be flanged in the extending direction, and then the flanged metal belt 1 is coiled to form an annular layered structure, so that the infrared metal honeycomb body is obtained.
By "in sequence" is meant that the edges of all of the coils are turned up toward the central axis of the infrared metal honeycomb body, or the edges of all of the coils are turned up toward the central axis away from the infrared metal honeycomb body. The purpose of this is, on the one hand, to make aesthetic sense and, on the other hand, to ensure a reduction in the air intake of each honeycomb cell 2.
Further, in order to increase the stability of the honeycomb holes 2, each layer of the coiled ring is provided with the protrusions 11, and the protrusions 11 of the two adjacent layers of the coiled rings are arranged in a staggered manner.
Preferably, in order to increase the porosity of the infrared metal honeycomb body to improve the ventilation efficiency, the protrusions 11 are hollow protrusions, and the hollow parts of the hollow protrusions are all communicated with the honeycomb holes 2.
The hollow parts of the hollow bulges are communicated with the honeycomb holes 2, and the hollow parts of the hollow bulges are communicated with the honeycomb holes 2 where the hollow bulges are located and the honeycomb holes 2 adjacent to the hollow bulges.
Preferably, the protrusions 11 are cylindrical, triangular-cylindrical, or semi-cylindrical, which can increase the contact area between the protrusions 11 and the metal band 1, thereby increasing the stability of the honeycomb holes 2.
Furthermore, the number of the metal strips 1 is one, and the metal strips 1 are provided with protrusions 11. When the metal strip 1 is wound to form an infrared metal honeycomb body having an annular layered structure, the protrusions 11 of the two adjacent coils are arranged to be offset from each other.
Further, the number of the metal strips 1 is at least two; each metal belt 1 is provided with a bulge 11; when a plurality of metal strips 1 are overlapped, the bulges 11 on any two adjacent metal strips 1 are arranged in a staggered way; the infrared metal honeycomb body is formed by coiling a plurality of metal strips 1 which are stacked.
Preferably, at least n rows of protrusions 11 are arranged on one metal strip of the two adjacent metal strips 11 at intervals, and at least n +1 rows of protrusions 11 are arranged on the other metal strip at intervals, where n is a positive integer not less than 1.
Preferably, the rows of projections 11 on each strip 1 are arranged parallel to each other.
For example, as shown in fig. 2-4, the metal strip 1 has four strips, and the first metal strip has three rows of protrusions 11 at intervals, and the three rows of protrusions 11 are parallel to each other; two rows of bulges 11 are arranged on the second metal strip at intervals, and the two rows of bulges 11 are parallel to each other; three rows of bulges 11 are arranged on the third metal strip at intervals, and the three rows of bulges 11 are mutually parallel; two rows of protrusions 11 are arranged on the fourth metal strip at intervals, and the two rows of protrusions 11 are parallel to each other. When the four metal strips are stacked together, the projections 11 of the four metal strips are arranged offset from each other.
And coiling the overlapped four metal strips to form a ring-shaped structure, thus obtaining the infrared metal honeycomb body.
Example 2
The present embodiment provides an infrared metal burner comprising a burner body, and the infrared metal honeycomb of embodiment 1; an infrared metal honeycomb is positioned within the burner body.
Since the infrared metal burner of this embodiment employs the infrared metal honeycomb of embodiment 1, the infrared metal burner of this embodiment can at least reduce the possibility of backfire.
