Description

Technical Field

[0001] The present invention relates to the technical field of burners, and in particular to a honeycomb body and a manufacturing method thereof. Background Art

[0002] Honeycomb is an important component of infrared burners. Currently, metal honeycomb bodies on the market are mainly divided into two types: a flat belt and a wavy belt, which are superimposed and wound together. However, the two belts will warp due to thermal expansion and contraction. Severe warping will cause tempering. Since the air outlet channel is vertical, the heat exchange effect of the honeycomb is poor. Especially during stir-frying and ignition, tempering is prone to occur due to poor fire transfer effect. Summary of the Invention

[0003] The object of the present invention is to provide a honeycomb body, which is formed by winding a metal thin strip having both the planar section and the corrugated section. The honeycomb body does not have the problem of local bulging (emerging) or downward movement, is not prone to warping, is not prone to causing tempering, has a simple structure and is low in cost. By setting different air outlet channels, the air outlet concentration / velocity around the inner periphery of the honeycomb body can be increased and gradually decreased outward, making it easier to ignite and transfer fire and avoiding deflagration.

[0004] The object of the present invention is to provide a method for manufacturing a honeycomb body.

[0005] To achieve the purpose of the present invention, the present invention adopts the following technical solutions:

The honeycomb body is connected to the top of a furnace head, the furnace head having at least two gas supply channels, and the honeycomb body has at least two annular gas outlet areas corresponding to the gas supply channels, each of the annular gas outlet areas being provided with a plurality of gas outlet channels.

[0007] According to one embodiment of the present invention, the honeycomb body includes a metal strip, which includes multiple planar segments and multiple corrugated segments. The metal strip is coiled to form a honeycomb body, wherein the planar segments and the corrugated segments cooperate to form the air outlet channel.

[0008] According to one embodiment of the present invention, the metal strip is wound to form a plurality of coils, and the coils include the planar section and the corrugated section. The outer side of the corrugated section is the planar section of the adjacent coil, and the outer side of the planar section is the corrugated section of the adjacent coil.

[0009] According to one embodiment of the present invention, there is at least one planar segment and at least one corrugated segment in each of the coils.

[0010] According to one embodiment of the present invention, the cross section of the corrugated section is an arc wave, the wavelength of the arc wave is 0.2 mm to 3 mm, and the wave height of the arc wave is 0.1 mm to 2 mm.

[0011] According to one embodiment of the present invention, the corrugated segments are corrugations inclined to the overall extending direction of the metal strip.

[0012] According to an embodiment of the present invention, the inclination angle of the air outlet channel is α, wherein 5°≤α≤45°.

[0013] According to one embodiment of the present invention, there are two annular air outlet areas, namely an inner ring air outlet area and an outer ring air outlet area located outside the inner ring air outlet area, and the inclination angle of the air outlet channel located inside the outer ring air outlet area is equal to the inclination angle of the air outlet channel located in the inner ring air outlet area.

[0014] According to one embodiment of the present invention, the inclination angle of the air outlet channel located in the outer ring area is α1, 30°≤α1≤45°;

[0015] The inclination angle of the air outlet channel located in the inner ring area is α2, 5°≤α2≤30°;

[0020] According to the pressing parameters, a plurality of the planar segments and a plurality of the corrugated segments are pressed out of the metal strip, wherein the corrugated segments are corrugations inclined to the overall extension direction of the metal strip;

[0021] The pressed metal strip is wound multiple times to form a honeycomb body.

[0028] By setting different gas outlet channels, the gas outlet concentration / speed inside the honeycomb body can be increased and gradually decreased outwards, making it easier to ignite and transmit fire. This can avoid temporary ignition due to insufficient concentration in the inner ring. The outer ring nozzle is larger and releases more gas to the outside of the pot. If the ignition is suddenly successful at this time, it will ignite the surrounding gas and scare the user.

[0036] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be embodied in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art. Like reference numerals in the figures represent like or similar structures, and thus their detailed description will be omitted.

[0037] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusive meaning and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.

[0038] A honeycomb body according to an embodiment of the present invention includes: a honeycomb body connected to the top of a furnace head, the furnace head having at least two air supply channels, the honeycomb body having at least two annular air outlet areas corresponding to the air supply channels, and each annular air outlet area being provided with a plurality of air outlet channels.

[0039] Among them, in the burner, a flame distribution plate is installed on the top of the burner, and a honeycomb body is installed on the top of the flame distribution plate. When the burner has two air supply channels, the inner ring area corresponds to the air supply channel on the inner side of the burner, and the outer ring area and the transition area are located on the air supply channel on the outer side of the burner; when the burner has three air supply channels, the inner ring area, the transition area and the outer ring area can respectively correspond to the three air supply channels from the inside to the outside on the burner. For correspondence, a partition can be installed between the honeycomb body and the flame distribution plate, and the partition divides the flame distribution plate into multiple chambers to correspond to the air supply channels on the burner. The partition part can be an annular partition, a cylinder, etc. For the convenience of illustration, this application takes a double ring as an example, and sets the partition part as follows Figure 2 The dividing line shown as P1 is such that the honeycomb body forms inner and outer ring regions.

[0040] The outlet direction of the air outlet channel is inclined to the plane where the top surface of the honeycomb body is located. Therefore, the angle between the outlet direction of the air outlet channel and the plane where the top surface of the honeycomb body is located is called the inclination angle of the air outlet channel. Due to the different inclination angles of the air outlet channel, the resistance to the gas will also be different, and the gas outlet speed at the fire hole will also be different. Among them, the smaller the inclination angle, the greater the outlet gas concentration / speed. Among any two adjacent annular air outlet areas, the inclination angle of the air outlet channel of the outer annular air outlet area is greater than or equal to the inclination angle of the air outlet channel of the inner annular air outlet area. This can increase the outlet gas concentration / speed around the honeycomb body and gradually decrease it outward, making it easier to ignite and transfer fire. This can avoid temporary ignition due to insufficient concentration in the inner ring during ignition. The outer ring nozzle is larger and releases more gas to the outside of the pot. If ignition is successful at this time, it will ignite the surrounding gas and scare the user.

[0041] In a preferred embodiment of the present invention, a metal strip 1 is provided, the metal strip 1 includes a plurality of planar segments 11 and a plurality of corrugated segments 12, the planar segments 11 and the corrugated segments 12 are alternately connected, and the metal strip 1 is formed into a honeycomb body by winding, wherein the planar segments 11 and the corrugated segments 12 cooperate to form an air outlet channel.

[0042] The present application uses a single-layer metal strip having both a flat section 11 and a corrugated section 12, which is formed into a regular corrugated shape by rolling or stamping. The flat section 11 and the corrugated section 12 surround each other to form an air outlet channel, wherein each wave segment of the corrugated section 12 can serve as an air outlet hole in the air outlet channel.

[0043] In the first case, the flat segment 11 and the corrugated segment 12 are connected alternately. The flat segment 11 can be located at the initial end of the metal strip 1. In this way, the end of the flat segment 11 is connected to the initial end of the corrugated segment 12. The initial end of the corrugated segment 12 is connected to the initial end of the next flat segment 11. The end of the next flat segment 11 is connected to the initial end of the next corrugated segment 12, and so on. Alternatively, the corrugated segment 12 can be located at the initial end of the metal strip 1 and then the flat segment 11 is provided. As long as the flat segment 11 and the corrugated segment 12 are provided alternately, it can be sufficient. It should be noted that the initial end of the metal strip 1 of this application is the side where the metal strip 1 is coiled, and the end corresponds to the initial end.

[0044] The second situation is that the flat segments 11 and the corrugated segments 12 are not alternately connected. For example, the first segment at the initial end of the metal strip 1 may be a flat segment 11, the second segment may be a corrugated segment 12, the third segment may also be a corrugated segment 12, the fourth segment may be a flat segment 11, and the fifth segment may also be a flat segment 11. This situation applies to the case where one coil 100 is provided with one flat segment 11 and one corrugated segment 12. Alternatively, the first segment at the initial end of the metal strip 1 may be a flat segment 11, the second segment may be a corrugated segment 12, the third segment may also be a flat segment 11, the fourth segment may be a corrugated segment 12, the fifth segment may also be a corrugated segment 12, the sixth segment may be a flat segment 11, the seventh segment may be a corrugated segment 12, the eighth segment may be a flat segment 11, the ninth segment may be a flat segment 11, and so on. Each coil 100 has two flat segments 11 and two corrugated segments 12. Of course, when there are multiple planar segments 11 and multiple corrugated segments 12 on the winding coil 100, the connection between two adjacent winding coils 100 is not that the planar segments 11 and the corrugated segments 12 are alternately connected, but rather that they are two identical shapes, either both are corrugated segments 12 or both are planar segments 11.

[0045] pass Figure 1 It can be seen from the honeycomb body shown that the honeycomb body also has multiple air outlet rings. In this application, the corrugated section 12 and the flat section 11 are used in conjunction with each other so that the waves on the corrugated section 12 serve as air outlet channels. Multiple corrugated sections 12 are evenly distributed along the honeycomb body, which ensures uniform air outlet while also stabilizing and evenly distributing the airflow and reducing the generation of smoke.

[0046] The metal strip 1 is coiled multiple times to form a honeycomb body. After the metal strip 1 is coiled, multiple coils 100 are formed. Therefore, the honeycomb body of the present application is composed of multiple mutually constrained coils 100. In addition, the flat section 11 and the corrugated section 12 are constrained to each other, and there will be no problem of local bulging (popping out) or downward movement. The honeycomb body is not easy to warp or cause tempering, and has a simple structure and low cost.

[0047] In addition, the cross-section of the honeycomb body can be in various shapes such as circle, ellipse, triangle, rectangle, hexagon, octagon, dodecagon, etc.

[0048] In a preferred embodiment of the present invention, the metal strip 1 is coiled to form a plurality of coils 100. The coils 100 include two types: a first coil 100a formed by coiling the flat section 11, and a second coil 100b formed by coiling the corrugated section 12.

[0049] The first winding coils 100a and the second winding coils 100b are alternately arranged.

[0050] Figure 1As shown, in the present application, the planar segment 11 can be coiled once to form a first coil 100a, and the corrugated segment 12 can be coiled once to form a second coil 100b. The second coil 100b is arranged outside the first coil 100a, and the first coil 100a is arranged outside the second coil 100b, and so on. Multiple first coils 100a and second coils 100b are alternately arranged to form a honeycomb body. In other words, each coil 100 in the honeycomb body represents a separate planar segment 11 or corrugated segment 12.

[0051] The innermost side of the honeycomb body may be the first coil 100a or the second coil 100b. Figure 1 The planar segment 11 is shown as the starting end of the metal strip 1, and after being wound once, a first winding circle 100a is formed, and then the corrugated segment 12 is wound around the outer periphery of the first winding circle 100a to form a second winding circle 100b. Then, the next planar segment 11 is wound around the outer periphery of the second winding circle 100b, and so on to form a honeycomb body.

[0052] Furthermore, the planar segment 11 can be wound multiple times as needed. Simply setting the length of the planar segment 11 and the number of turns required before pressing is sufficient. The lengths of the different planar segments 11 and corrugated segments 1212 can be calculated based on parameters such as the predetermined inner and outer diameters of the honeycomb, the thickness of the metal strip 1, and the wave height of the corrugated segment 12.

[0053] The first coils 100a and the second coils 100b of the present application are alternately arranged, and the multiple waves on the corrugated section 12 can separate the space between two adjacent first coils 100a into multiple uniform air outlet channels, which can play a role in stabilizing and evenly distributing the airflow.

[0054] In a preferred embodiment of the present invention, the metal strip 1 is wound to form a plurality of coils 100, and the coils 100 include a planar section 11 and a corrugated section 12. The outer side of the corrugated section 12 is the planar section 11 of the adjacent coil 100, and the outer side of the planar section 11 is the corrugated section 12 of the adjacent coil 100.

[0055] In a preferred embodiment of the present invention, each coil 100 includes at least one flat section 11 and at least one corrugated section 12 .

[0056] After the metal strip 1 is coiled, a plurality of coils 100 are formed. Each coil 100 can include a flat segment 11 and a corrugated segment 12 at the same time. No corresponding drawings are added to the specification. Each coil 100 has one flat segment 11 and one corrugated segment 12. Of course, two flat segments 11 and two corrugated segments 12 can also be set in each coil 100. Of course, the number of flat segments 11 and corrugated segments 12 on each coil 100 can also be 3, 4, 5, 6, 8, 9, 10, 12 or even more, and this application does not impose any restrictions on this.

[0057] As long as the outer ring of the flat section 11 on adjacent coils 100 is a corrugated section 12, and the outer ring of the corrugated section 12 is a flat section 11, that is, the flat section 11 and the corrugated section 12 are arranged alternately from the inner ring to the outer ring, the outlet holes are evenly distributed on the outlet surface, ensuring uniform air outlet. Here, the outlet holes are the wave segments on the corrugated section 12, and each wave can serve as an outlet hole, ensuring uniform air outlet, stable flame, and less smoke.

[0058] In a preferred embodiment of the present invention, an annular body is further included, wherein the metal strip 1 is coiled around the outer circumference of the annular body 2 .

[0059] The initial end of the planar segment 11 can be connected to the outer periphery of the annular body, that is, a circle or a section of the planar segment 11 is wrapped around the annular body, or the corrugated segment 1212 can be directly coiled around the outer periphery of the annular body, which can increase the overall strength of the entire metal honeycomb body.

[0060] In a preferred embodiment of the present invention, the corrugated section 12 includes a plurality of wave crests 121 and a plurality of wave troughs 122 ; and a transition section 101 is provided between two adjacent coils 100 .

[0061] like Figure 1 As shown, the corrugation section 12 includes multiple peaks 121 and multiple troughs 122, wherein the peak near the starting end of the corrugation section 12 is the first peak, the trough near the starting end of the corrugation section 12 is the first trough, the peak near the end of the corrugation section 12 is the Nth peak, and the trough near the end of the corrugation section 12 is the Nth trough.

[0062] In such Figure 1 In the honeycomb body shown, part of the transition section 101 is connected between the first crest and the Nth crest on the same corrugated section 12, and the remaining part of the transition section 101 is connected between the first trough and the Nth trough. An irregular quadrilateral is formed by connecting the adjacent first winding coil 100a and the second winding coil 100b through two transitions, the first crest and the Nth crest, and the first trough and the Nth trough. The quadrilateral can be used to coil the corrugated section 12 into a whole, and the corrugated section 12 and the planar section 11 can be tightly connected to form a whole, thereby avoiding the problem of warping of the honeycomb body.

[0063] exist Figure 1In the honeycomb body shown, a transition section 101 is provided between two adjacent coils 100. Because the inner side of the coiled planar section 11 is in close contact with the outer periphery of the corrugated section 12 located on the inner circle, the first coiled coil 100 located on the inner side has the corrugated section 12 at the initial end and the planar section 11 at the end. When the planar section 11 is coiled toward the outer circle, it needs to coil from the trough 122 of the corrugated section 12 at the initial end to its crest 121, and continue to coil against the outer periphery of the corrugated section 12 to form the second coiled coil 100. Generally, the initial end of the second winding coil 100 is a flat section 11, and the end is a corrugated section 12. When the corrugated section 12 at the end of the winding coil 100 is wound to the third winding coil 100, the transition section 101 will be connected from the Nth wave peak of the second corrugated section 12 at the end of the second winding coil 100 to the first wave valley of the corrugated section 12 at the initial end of the third winding coil 100. At the same time, the inner side of the transition section 101 will abut against the first wave peak of the second corrugated section 12 at the initial end of the second winding coil 100. This cycle is repeated to form a tightly connected honeycomb body, thereby avoiding the problem of honeycomb body warping caused by local upward bulging (emerging) or downward movement.

[0064] In a preferred embodiment of the present invention, the cross section of the corrugated section 12 is an arc wave, the wavelength of the arc wave is 0.2 mm to 3 mm, and the wave height of the triangular wave is 0.1 mm to 2 mm.

[0065] like Figure 1 As shown, whether the corrugated segments 12 form a single coil 100 or are a regular band, each wave is triangular in shape, and adjacent waves are of the same size and shape, exhibiting central symmetry. This results in an aesthetically pleasing honeycomb structure, simplified manufacturing, and uniform air outlet pores. Generally, the waves of the corrugated segments 12 on the same outlet ring are of uniform size. The cross-section of the corrugated segments 12 can be triangular, rectangular, trapezoidal, hexagonal, or other shapes.

[0066] Of course, the wave sizes on the corrugated section 12 may also be different, especially the corrugated section 12 located on the inner circle and the corrugated section 12 located on its outer circle. The wave sizes may be different. For example, the air outlet of the outer circle may be larger than the air outlet of the inner circle. In some cases, the air outlet of the inner circle may be larger than the air outlet of the outer circle to increase the central firepower.

[0067] In a preferred embodiment of the present invention, the corrugated section 12 is a corrugation inclined to the overall extension direction of the metal strip 1 .

[0068] like Figure 1As shown, the outlet channel of the corrugated section 12 is inclined relative to the overall extension direction of the metal strip 1. In other words, the outlet channel of the corrugated section 12 is tilted. Compared with conventional vertical outlet channels, this provides a longer channel, which increases the flow time of the gas or mixed gas and improves the heat exchange effect of the gas or mixed gas. Furthermore, the inclined shape of the corrugated section 12 increases the cross-sectional area of ​​the channel, which improves the heat radiation effect.

[0069] In a preferred embodiment of the present invention, the inclination angle of the air outlet channel is α, wherein 5°≤α≤45°.

[0070] like Figure 1 and 3 As shown, the inclination angle of the gas outlet channel in this application is the angle between the inclination direction of the corrugated section 12 and the overall extension direction of the metal strip 1. The inclination direction of the gas outlet channel is set from bottom to top. When the angle is 5°≤α≤45°, the gas encounters less resistance, which can increase heat exchange and improve heat radiation effect.

[0071] In a preferred embodiment of the present invention, there are two annular air outlet areas, namely an inner ring air outlet area and an outer ring air outlet area located on the periphery of the inner ring air outlet area, and the inclination angle of the air outlet channel located on the inner side of the outer ring air outlet area is equal to the inclination angle of the air outlet channel located in the inner ring air outlet area.

[0072] Among them, this application is aimed at the double-ring burner, which divides the honeycomb body into the inner ring gas outlet area and the outer ring gas outlet area, which is more in line with the requirements of production and installation. Figure 2 As shown, line P1 is the dividing line between the inner ring area and the outer ring air outlet area, and the area between line P1 and line P2 is the transition area, that is, line P2 is the dividing line between the transition area and the outer ring area. Figure 2 It is not difficult to see that in the two adjacent annular areas, the inclination angle of the air outlet channel in the transition area is equal to that of the air outlet channel in the inner annular area. This facilitates smooth fire transmission through the inner air outlet channel and improves fire transmission efficiency. The inclination angle of the air outlet channel outside the outer annular area is greater than or equal to that of the air outlet channel in the inner annular area. This can avoid deflagration caused by excessive air outlet velocity in the outer ring of the honeycomb body and improve the user experience.

[0073] In a preferred embodiment of the present invention, the inclination angle of the gas outlet channel located in the outer ring gas outlet area is α1, 30°≤α1≤45°;

[0074] The inclination angle of the air outlet channel located in the inner ring air outlet area is α2, 5°≤α2≤30°;

[0075] Among them, α2≤α1.

[0076] like Figure 2As shown, the different inclination angles of the gas outlet channel will result in different resistances to the gas passing through the gas outlet channel, and the gas outlet velocity at the fire hole will also be different. When the inclination angle α2 of the gas outlet channel in the inner ring area is greater than or equal to 5° and less than or equal to 30°, the gas outlet velocity and gas concentration will increase, which is conducive to ignition.

[0077] The inclination angle of the gas outlet channel in the outer ring area is greater than or equal to the inclination angle of the gas outlet channel in the inner ring area, so α2≤α1. This design can avoid temporary ignition due to insufficient concentration in the inner ring during ignition. The outer ring nozzle is larger and releases more gas to the outside of the pot. If the ignition is suddenly successful at this time, it will ignite the surrounding gas, including the gas overflowing outside the pot, which will scare the user.

[0078] A method for manufacturing a honeycomb body according to an embodiment of the present invention includes:

[0079] Selecting a metal thin strip 1 and determining basic parameters of a prefabricated honeycomb body;

[0080] Calculate the lengths of the flat section 11 and the corrugated section 12 based on the basic parameters of the honeycomb body;

[0081] According to the obtained lengths of the flat segments 11 and the corrugated segments 12, multiple flat segments 11 and multiple corrugated segments 12 are pressed out on the metal strip 1, and the corrugated segments 12 are corrugations inclined to the overall extension direction of the metal strip 1; then the metal strip 1 is coiled multiple times to form a honeycomb body.

[0082] The pressing method of the present application can be rolling, stamping, etc., as long as the flat section 11 and the corrugated section 12 can be formed on the metal strip 1 at the same time, wherein the corrugated section 12 is a corrugation inclined to the overall extension direction of the metal strip 1, so that the gas outlet channel is inclined. By controlling the inclination angle of the gas outlet channel on different corrugated sections 12, the inclination angle of the gas outlet channel in the outer annular gas outlet area of ​​two adjacent annular gas outlet areas can be greater than or equal to the inclination angle of the gas outlet channel in the inner annular gas outlet area. By increasing the gas outlet concentration / speed around the honeycomb body, ignition and fire transmission are easier, and temporary ignition due to insufficient concentration in the inner ring can be avoided. The outer ring nozzle is larger and releases more gas to the outside of the pot. If ignition is suddenly successful at this time, it will ignite the surrounding gas and scare the user.

[0083] The specific coiling structure of the honeycomb body is as follows: In the first case, the flat segment 11 and the corrugated segment 12 are connected alternately. For example, the flat segment 11 is located at the initial end of the metal strip 1, and the end of the flat segment 11 is connected to the initial end of the corrugated segment 12. The initial end of the corrugated segment is connected to the initial end of the next flat segment 11, and the end of the next flat segment 11 is connected to the initial end of the next corrugated segment 12, and so on. At the same time, the corrugated segment 12 can also be located at the initial end of the metal strip 1 and then the flat segment 11 is set, as long as the flat segment 11 and the corrugated segment 12 are arranged alternately. It should be noted that the initial end of the metal strip 1 of this application is the side where the metal strip 1 is coiled, and the end corresponds to the initial end. The second situation is that the flat segments 11 and the corrugated segments 12 are not alternately connected. For example, the first segment at the initial end of the metal strip 1 may be a flat segment 11, the second segment may be a corrugated segment 12, the third segment may also be a corrugated segment 12, the fourth segment may be a flat segment 11, and the fifth segment may also be a flat segment 11. This situation applies to the case where one coil 100 is provided with one flat segment 11 and one corrugated segment 12. Alternatively, the first segment at the initial end of the metal strip 1 may be a flat segment 11, the second segment may be a corrugated segment 12, the third segment may also be a flat segment 11, the fourth segment may be a corrugated segment 12, the fifth segment may also be a corrugated segment 12, the sixth segment may be a flat segment 11, the seventh segment may be a corrugated segment 12, the eighth segment may be a flat segment 11, the ninth segment may be a flat segment 11, and so on. Each coil 100 has two flat segments 11 and two corrugated segments 12. Of course, when there are multiple planar segments 11 and multiple corrugated segments 12 on the winding coil 100, the connection between two adjacent winding coils 100 is not that the planar segments 11 and the corrugated segments 12 are alternately connected, but rather that they are two identical shapes, either both are corrugated segments 12 or both are planar segments 11.

[0084] The metal strip 1 is wound multiple times by the equipment to form a honeycomb body. After being wound, the metal strip 1 is formed into multiple coils 100. Therefore, the honeycomb body of the present application is composed of multiple mutually constrained coils 100, and the flat sections 11 and the corrugated sections 12 are alternately connected, so that the honeycomb body will not have the problem of local bulging (popping) upward or moving downward, and it is not easy to warp or cause tempering. It has a simple structure and low cost.

[0085] In a preferred embodiment of the present invention, the basic parameters of the honeycomb body include the inner diameter of the honeycomb body, the size of the air outlet 10, and the air outlet direction. The pressing parameters include the length of the flat section 11, the length of the corrugated section 12, the inclination angle of the corrugated section 12, and the size of each wave in the corrugated section 12. The inclination angle of the corrugated section 12 and the size of each wave in the corrugated section 12 are determined based on the basic parameters of the honeycomb body and the thickness of the metal strip 1.

[0086] The basic parameters of the honeycomb body can be the inner diameter of the honeycomb body a, the circumference of the coil 100 S, the size of the outlet hole. Since the outlet hole of the present application is equivalent to each wave of the corrugated section 12, the size of the outlet hole is the wave height d and the wavelength c of the corrugated section 12. In addition, assuming that the thickness of the metal strip 1 is b, the circumference of the i-th coil 100 is S i ,but:

[0087] S i =π[a+(i-1)(b+d)].

[0088] Here, i represents the number from the inside to the outside, and the wave height is the height from the inner side of the wave crest 121 to the lowest point of the wave trough 122, that is, the distance from the highest point on the inner side of a wave crest 121 to the outer periphery of the plane segment 11 located on the inner side of the wave.

[0089] The lengths of different coils 100 can be calculated through the above process. When the flat section 11 and the corrugated section 12 are each wound around once to form a coil, the lengths of different coils 100 are the lengths of the flat section 11 and the corrugated section 12. If the coil 100 has m flat sections 11 and m corrugated sections 12, then the lengths of the flat section 11 and the corrugated section 12 are S. i / 2n, if the corrugated segment 12 is the initial end of the i-th winding circle, then the initial position of the first corrugated segment 12 of the i-th winding circle is S i-1 , the end position is S i-1 +S i / 2m, the initial position of the second corrugated section 12 of the next i-th circle is an S i-1 +S i / m, the end position is S i-1 +S i 3 / 2m, and so on. Therefore, the initial positions of the different corrugated segments 12 can be determined. The size of each wave in the honeycomb can then be determined based on the size of the outlet holes 10. The inclination angle of the corrugated segments 12 can be calculated based on the outlet direction of the outlet holes in the honeycomb. The size of each wave in the honeycomb can then be determined based on the size of the outlet holes 10.

[0090] Therefore, by inputting the above information into the control system, the control system can calculate and convert it into the pressing parameters of the pressing equipment, that is, the system can match the lengths of different plane segments 11 and corrugated segments 12, and can also calculate the shape and size of the waves in the corrugated segments 12 and the inclination angle of the corrugated segments 12, and then press the metal strip 1 according to these parameters.

[0091] In this application, the corrugated section 12 and the flat section 11 cooperate with each other, so that the waves on the corrugated section 12 serve as the air outlet channel. Multiple corrugated sections 12 are evenly distributed along the honeycomb body, which ensures uniform air outlet while also stabilizing the airflow pressure and evenly distributing it, thereby reducing the generation of smoke.

[0092] In addition, the cross-section of the honeycomb body can be in various shapes such as circle, ellipse, triangle, rectangle, hexagon, octagon, dodecagon, etc., and this application does not impose any limitation thereto.

[0093] In a preferred embodiment of the present invention, the planar section 11 is coiled once to form a first coil 100a, and the corrugated section 12 is coiled once to form a second coil 100b. The second coil 100b is arranged outside the first coil 100a, and the first coil 100a is arranged outside the second coil 100b. A honeycomb body is formed by alternating a plurality of first coils 100a and second coils 100b.

[0094] In a preferred embodiment of the present invention, one of the first coil 100a or the second coil 100b is disposed at the innermost side of the honeycomb body.

[0095] Figure 1 As shown, in the present application, the planar segment 11 can be coiled once to form a first coil 100a, and the corrugated segment 12 can be coiled once to form a second coil 100b. The second coil 100b is arranged outside the first coil 100a, and the first coil 100a is arranged outside the second coil 100b, and so on. Multiple first coils 100a and second coils 100b are alternately arranged to form a honeycomb body. In other words, each coil 100 in the honeycomb body represents a separate planar segment 11 or corrugated segment 12.

[0096] The innermost side of the honeycomb body may be the first coil 100a or the second coil 100b. Figure 1 The planar segment 11 is shown as the starting end of the metal strip 1, and after being wound once, a first winding circle 100a is formed, and then the corrugated segment 12 is wound around the outer periphery of the first winding circle 100a to form a second winding circle 100b. Then, the next planar segment 11 is wound around the outer periphery of the second winding circle 100b, and so on to form a honeycomb body.

[0097] Furthermore, the planar segment 11 can be wound multiple times as needed. Simply setting the length of the planar segment 11 and the number of turns required before pressing is sufficient. The lengths of the different planar segments 11 and corrugated segments 12 can be calculated based on parameters such as the predetermined inner and outer diameters of the honeycomb, the thickness of the metal strip 1, and the wave height of the corrugated segments 12.

[0098] The first coils 100a and the second coils 100b of the present application are alternately arranged, and the multiple waves on the corrugated section 12 can separate the space between two adjacent first coils 100a into multiple uniform air outlet channels, which can play a role in stabilizing and evenly distributing the airflow.

[0099] In a preferred embodiment of the present invention, the lengths of the flat section 11 and the corrugated section 12 are adjusted so that each winding coil 100 has both a flat section 11 and a corrugated section 12, and the outer side of the corrugated section 12 is the flat section 11 of the adjacent winding coil 100, and the outer side of the flat section 11 is the corrugated section 12 of the adjacent winding coil 100.

[0100] Each coil 100 may be composed of one flat segment 11 and one corrugated segment 12, or may be composed of two flat segments 11 and two corrugated segments 12. Of course, the number of flat segments 11 and corrugated segments 12 on each coil 100 may also be 3, 4, 5, 6, 8, 9, 10, 12, or even more. This application does not impose any limitation on this.

[0101] When pressing the metal strip 1, it is only necessary to calculate the length of each flat segment 11 and corrugated segment 12 based on the inner and outer diameters of the honeycomb body, the number of flat segments 11 and corrugated segments 12 on each winding ring 100, the thickness of the metal strip 1, the wave height and wavelength of the corrugated segment 12. The system calculates the length of each flat segment 11 and corrugated segment 12 according to the relationship between the different inner and outer diameters, and then inputs it into the control system. The control system controls, for example, a roller press to perform rolling according to the set program, and then outputs the flat segment 11 and corrugated segment 12 on a metal strip 1.

[0102] In this application, the outer ring of the flat section 11 on adjacent coils 100 is the corrugated section 12, and the outer ring of the corrugated section 12 is the flat section 11. That is, the flat section 11 and the corrugated section 12 are arranged alternately from the inner ring to the outer ring, ensuring that the outlet holes are evenly distributed on the outlet surface, ensuring uniform air outlet. Here, the outlet holes are the wave segments on the corrugated section 12, and each wave can serve as an outlet hole, ensuring uniform air outlet, stable flame, and less smoke.

[0103] In a preferred embodiment of the present invention, the planar segment 11 is coiled around the outer circumference of the annular body; alternatively, the corrugated segment 12 is coiled around the outer circumference of the annular body. The planar segment 11 can be coiled one or more times to increase the thickness of the honeycomb inner wall and improve the overall compressive strength. The corrugated segment 12 can also be coiled around the outer circumference of the annular body. The annular body in this application can be a steel ring or other annular object.

[0104] The specific operation is: use a small flat segment 11 to connect with the annular body, or directly use a corrugated belt to connect with the annular body, and then wind it to form a honeycomb body. You can also use an annular body to replace the first flat segment 11, connect the corrugated segment 12 to the outer periphery of the steel ring, and then wind the flat segment 11 connected to the corrugated segment 12 around the outer periphery of the corrugated segment 12 to finally form a honeycomb body.
