Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to an energy-concentrating disc and burner. Background Technology

[0002] A concentrating plate is installed on the burner to improve combustion thermal efficiency. This plate has an exhaust port for discharging the flue gas produced during combustion. Currently, the exhaust ports of concentrating plates on the market are all located on the same plane with a uniform exhaust height. As the requirements for improving the thermal efficiency of the concentrating plate increase, this is often achieved by lowering the height of the exhaust port. However, this method also leads to a significant increase in the height of the flue gas produced during combustion, limiting the improvement of burner performance. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of low thermal efficiency and high flue gas content of the energy-concentrating disc in the existing burner, and to provide an energy-concentrating disc and burner.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This utility model provides an energy-concentrating plate, which includes a plate body and corner pieces. The corner pieces are spaced apart along the circumference of the plate body. The energy-concentrating plate also includes a flow-dividing platform, which is disposed on the plate body and protrudes upward from the top surface of the plate body. The corner pieces are connected to the flow-dividing platform and are used to support the bottom of the pot. A gap is formed between the multiple flow-dividing platforms, which is used to form a main exhaust port with the bottom of the pot, and a secondary exhaust port is formed between the flow-dividing platform and the bottom of the pot.

[0006] In this design, the energy-concentrating plate includes a plate body, corner plates, and a distribution platform. The distribution platform is located on the plate body, and the corner plates are connected to the distribution platform and support the bottom of the pot. The distribution platform protrudes upward from the top surface of the plate body, forming gaps between multiple distribution platforms. The gaps and the bottom of the pot form the main exhaust port, from which most of the flue gas is discharged. A secondary exhaust port is formed between the distribution platform and the bottom of the pot. The flue gas generated during combustion flows radially from the inner side to the outer side of the energy-concentrating plate. Due to the obstruction of the corner plates, the amount of flue gas flowing near the corner plates is relatively small. The distribution platform at the corner plates results in a lower height for the secondary exhaust port, allowing the flue gas to be closer to the bottom of the pot, making it easier for heat to transfer to the bottom. This results in more heat radiated from the energy-concentrating plate to the bottom of the pot, and the space between the bottom of the pot and the energy-concentrating plate reduces the heat dissipation area, significantly improving thermal efficiency. Although the secondary exhaust port is lower in height, the amount of flue gas there is also smaller, preventing high flue gas levels. This achieves both improved thermal efficiency and avoids the generation of high flue gas volumes.

[0007] Preferably, the flow divider includes a first part and a second part, which are respectively disposed on both sides of the corner piece.

[0008] In this scheme, by placing the first part and the second part on both sides of the corner plate, the corner plate can split the flue gas into two parts of flue gas flow, and the two parts of flue gas flow flow through the auxiliary exhaust ports above the first part and the second part respectively, thereby reducing the amount of flue gas in each part and avoiding the generation of high flue gas.

[0009] Preferably, the angle between the two ends of the first part and the line connecting the center of the energy-concentrating disk is α, and the angle between the two ends of the second part and the line connecting the center of the energy-concentrating disk is β, where |ab|≤25° and a+b≤45°.

[0010] In this scheme, by setting the range of a and b within |ab|≤25°, the difference between the first part and the second part is avoided to be too large, so that the effect of reducing smoke on both sides of the corner plate is more balanced. Furthermore, by setting a+b≤45°, the size of the secondary exhaust port is kept within a suitable range, thereby avoiding the secondary exhaust port being too large and the main exhaust port being too small, ensuring that the smoke can be fully discharged.

[0011] Preferably, the height of the diverter protruding from the disk body is H1, 0.3mm≤H1≤5mm, and the height of the corner plate protruding from the disk body is H2, H1-H2≥6mm.

[0012] In this scheme, by setting the height H1 of the diversion platform protruding from the disc body within the range of 0.3mm≤H1≤5mm, and setting the height H2 of the corner plate protruding from the disc body within the range of H1-H2≥6mm, the heights of the main exhaust port and the auxiliary exhaust port can be within a suitable range, which can effectively improve thermal efficiency and ensure that the flue gas can be effectively discharged while avoiding excessive flue gas height.

[0013] Preferably, the diversion platform is located at one end of the corner plate near the radially outer side of the energy-concentrating disk.

[0014] In this scheme, by placing the diversion platform at one end of the corner plate near the radial outer side of the energy-concentrating plate, the auxiliary exhaust port can be located at one end of the radial outer side of the energy-concentrating plate, so that the flue gas on the radial inner side of the energy-concentrating plate can fully pass through the auxiliary exhaust port, thereby improving the effect of reducing flue gas.

[0015] Preferably, the diversion platform extends along the circumferential direction of the energy-concentrating disk.

[0016] In this solution, by setting the diversion platform to extend along the circumferential direction of the energy-concentrating plate, the secondary exhaust port formed between the diversion platform and the bottom of the pot can also extend along the circumferential direction of the energy-concentrating plate. This is more conducive to the exhaust gas flowing out radially inward from the energy-concentrating plate passing through the secondary exhaust port, further improving the effect of reducing exhaust gas.

[0017] Preferably, the disc body is a shell, and the shell has a cavity inside.

[0018] In this design, the plate is a shell with an internal cavity. The cavity enhances the heat concentration effect of the energy-concentrating plate and improves its thermal efficiency.

[0019] Preferably, the flow divider has a hollow structure, and the interior of the flow divider is connected to the cavity.

[0020] In this solution, by setting the distribution platform as a hollow structure and connecting the interior of the distribution platform with the cavity, the internal cavity volume of the disk is increased, thereby further improving the thermal efficiency of the energy-concentrating disk.

[0021] Preferably, the disc body includes an inclined guide section and a planar smoke exhaust section. One end of the planar smoke exhaust section is connected to the top of the inclined guide section, and the other end of the planar smoke exhaust section extends horizontally outward along the radial direction of the energy-concentrating disc. The flow distribution platform is disposed on the planar smoke exhaust section and protrudes upward.

[0022] In this design, the disc body includes an inclined guide section and a planar exhaust section. The inclined guide section guides the flue gas to the planar exhaust section. The diversion platform is set on the planar exhaust section and protrudes upward, thereby forming a main exhaust port and a secondary exhaust port on the planar exhaust section. The flue gas guided by the inclined guide section reaches the planar exhaust section and is then discharged from the main exhaust port and the secondary exhaust port. By setting the inclined guide section and the planar exhaust section, it is more conducive to guiding the flow direction of the flue gas, so that the energy-concentrating disc can better reduce the flue gas effect.

[0023] This utility model also provides a burner, which includes the above-mentioned energy-concentrating disc.

[0024] The positive and progressive effects of this utility model are as follows:

[0025] The energy-concentrating plate includes a plate body, corner plates, and flow-diverting platforms. The flow-diverting platforms are located on the plate body, and the corner plates are connected to the flow-diverting platforms and support the bottom of the pot. The flow-diverting platforms protrude upwards from the top surface of the plate body, forming gaps between multiple flow-diverting platforms. These gaps, along with the bottom of the pot, form the main exhaust port, from which most of the flue gas is discharged. A secondary exhaust port is formed between the flow-diverting platforms and the bottom of the pot. The flue gas generated during combustion flows radially from the inner to the outer side of the energy-concentrating plate. Due to the obstruction of the corner plates, the amount of flue gas flowing near the corner plates is relatively small. The flow-diverting platforms at the corner plates result in a lower height for the secondary exhaust port, allowing the flue gas to be closer to the bottom of the pot, making heat transfer easier. This results in more heat radiated from the energy-concentrating plate to the bottom of the pot, and the space between the pot bottom and the energy-concentrating plate reduces the heat dissipation area, significantly improving thermal efficiency. Although the secondary exhaust port is lower in height, the amount of flue gas there is also smaller, preventing high flue gas levels. This approach improves thermal efficiency while avoiding the generation of high flue gas volumes. Attached Figure Description

[0045] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0046] This embodiment provides a burner, which includes a concentrating disk 100.

[0047] like Figure 1As shown, the energy-concentrating plate 100 includes a plate body 200 and corner pieces 300. The corner pieces 300 are spaced apart circumferentially along the plate body 200. The energy-concentrating plate 100 also includes a flow-diverting platform 400, which is disposed on the plate body 200 and protrudes upward from the top surface of the plate body 200. The corner pieces 300 are connected to the flow-diverting platform 400 and are used to support the bottom of the pot. Gaps are formed between the multiple flow-diverting platforms 400, which are used to form the main exhaust port 500 between the platform and the bottom of the pot. Figure 1 As shown in the first flue gas flow diagram, most of the flue gas is discharged from the main exhaust port 500. A secondary exhaust port 600 is formed between the diversion platform 400 and the bottom of the pot, as shown... Figure 1 As shown in the second flue gas flow diagram, the flue gas generated by combustion flows out radially from the inner side to the outer side of the energy-concentrating plate 100. Due to the obstruction of the corner plate 300, the amount of flue gas flowing near the corner plate 300 is relatively small. A diversion platform 400 is set at the corner plate 300, which makes the height of the secondary exhaust port 600 lower. The flue gas here is closer to the bottom of the pot, and the heat is more easily transferred to the bottom of the pot. The energy-concentrating plate 100 radiates more heat to the bottom of the pot, and the space between the bottom of the pot and the energy-concentrating plate 100 and the external heat dissipation area are reduced, which significantly improves the thermal efficiency. Although the height of the secondary exhaust port 600 is small, the amount of flue gas here is also small, which will not lead to the problem of high flue gas volume. Thus, while improving thermal efficiency, high flue gas volume is avoided.

[0048] The diversion platform 400 includes a first part 410 and a second part 420. The first part 410 and the second part 420 are respectively located on both sides of the corner plate 300. The corner plate 300 can divert the flue gas into two parts of flue gas flow, and the two parts of flue gas flow flow through the auxiliary exhaust port 600 above the first part 410 and the second part 420 respectively, thereby reducing the amount of flue gas in each part and avoiding the generation of high flue gas.

[0049] The angle between the two ends of the first part 410 and the center of the energy-concentrating disk 100 is 'a', and the angle between the two ends of the second part 420 and the center of the energy-concentrating disk 100 is 'b', where |ab|≤25° and a+b≤45°. By setting the range of a and b within |ab|≤25°, the difference between the first part 410 and the second part 420 is avoided from being too large, resulting in a more balanced smoke reduction effect on both sides of the corner plate 300. Furthermore, setting a+b≤45° ensures that the size of the secondary exhaust port 600 is within a suitable range, preventing the secondary exhaust port 600 from being too large and the main exhaust port 500 from being too small, thus ensuring that the smoke can be fully discharged. Those skilled in the art can fine-tune the size of the first part 410 and the second part 420 according to the layout of the outer ring burner cap, thereby improving the smoke reduction effect.

[0050] like Figure 2 and Figure 3As shown, the height of the diversion platform 400 protruding from the disc 200 is H1, where 0.3mm ≤ H1 ≤ 5mm, and the height of the corner piece 300 protruding from the disc 200 is H2, where H1 - H2 ≥ 6mm. By setting the height H1 of the diversion platform 400 protruding from the disc 200 within the range of 0.3mm ≤ H1 ≤ 5mm, and setting the height H2 of the corner piece 300 protruding from the disc 200 within the range of H1 - H2 ≥ 6mm, the heights of the main exhaust port 500 and the auxiliary exhaust port 600 can be kept within a suitable range, which can effectively improve thermal efficiency and ensure that the flue gas is effectively discharged while avoiding excessive flue gas height.

[0051] In this embodiment, the diversion platform 400 is located at the radially outer end of the corner plate 300 near the energy-concentrating disk 100, thereby allowing the secondary exhaust port 600 to be located at the radially outer end of the energy-concentrating disk 100. This ensures that the flue gas radially inner to the energy-concentrating disk 100 can fully pass through the secondary exhaust port 600, resulting in better flue gas reduction. In other embodiments, the diversion platform 400 may also extend to the middle of the energy-concentrating disk 100. Those skilled in the art can set the specific position of the diversion platform 400 according to actual needs.

[0052] In this embodiment, the diversion platform 400 extends along the circumferential direction of the energy-concentrating plate 100, thereby enabling the secondary exhaust port 600 formed between the diversion platform 400 and the bottom of the pot to also extend along the circumferential direction of the energy-concentrating plate 100. This facilitates the passage of flue gas flowing radially inward from the energy-concentrating plate 100 through the secondary exhaust port 600, further enhancing the flue gas reduction effect. In other embodiments, those skilled in the art can select a suitable extension direction of the diversion platform 400 according to actual needs.

[0053] like Figure 4 As shown, the disk body 200 is a shell 210, and the interior of the shell 210 is provided with a cavity 220. By setting the cavity 220, the heat gathering effect of the energy-concentrating disk 100 can be enhanced and the thermal efficiency of the energy-concentrating disk 100 can be improved.

[0054] The flow distribution platform 400 has a hollow structure, and its interior is connected to the cavity 220, which makes the cavity 220 inside the disk 200 larger and further improves the thermal efficiency of the energy-concentrating disk 100.

[0055] The disc body 200 includes an inclined guide section 230 and a flat exhaust section 240. One end of the flat exhaust section 240 is connected to the top of the inclined guide section 230, and the other end of the flat exhaust section 240 extends horizontally outward along the radial direction of the energy-concentrating disc 100. A diversion platform 400 is disposed on the flat exhaust section 240 and protrudes upward, thereby forming a main exhaust port 500 and a secondary exhaust port 600 on the flat exhaust section 240. The flue gas guided by the inclined guide section 230 reaches the flat exhaust section 240 and is then discharged from the main exhaust port 500 and the secondary exhaust port 600. By setting the inclined guide section 230 and the flat exhaust section 240, it is more conducive to guiding the flow direction of the flue gas, so that the energy-concentrating disc 100 can reduce the flue gas effect better.
