In addition, the terms "first" and "second" are merely used to distinguish in description and have no special meaning.
[0035] The embodiment provides an inner ring fire cover 10, so that the inner ring fire is more fully combusted, energy saving and cost reduction. As shown in Figure 1 and Figure 2As shown, an independent first gas chamber 1 and a first gas supply chamber 2 are formed on the lower side of the inner ring burner cap 10. The first gas chamber 1 and the first gas supply chamber 2 are concentrically arranged, with the first gas chamber 1 located outside the first gas supply chamber 2. A ring of first flame holes 31 is opened at the top of the inner ring burner cap 10. Each first flame hole 31 is connected to the first gas chamber 1 so that the gas overflowing from the ring of first flame holes 31 is ignited to form a first inner ring flame. A ring of first air holes 52 is opened in the inner ring burner cap 10. The ring of first air holes 52 is located inside the ring of first flame holes 31. Each first air hole 52 is connected to the first gas supply chamber 2. The first air holes 52 are inclined from bottom to top in a direction away from the center of the inner ring burner cap 10 to form a first tilt angle α so that the air overflowing from the first air holes 52 is directed toward the root of the first inner ring flame.
[0036] The aforementioned inner ring burner cap 10 tilts the outlet of the first vent 52 away from the center of the inner ring burner cap 10, making the outlet of the first vent 52 closer to the first inner ring flame formed by multiple first flame holes 31. When the gas is burning, the air overflowing from the first vent 52 directly acts on the root of the first inner ring flame. Because the oxygen content at the root of the first inner ring flame increases, the gas overflowing from the first flame hole 31 burns more completely, resulting in energy saving and cost reduction.
[0037] Optionally, such as Figure 1 As shown, a first annular groove 3 is formed at the top of the inner ring flame cap 10, and a ring of first flame holes 31 are formed at the bottom of the first annular groove 3. Figure 1 The cross-section does not reach the position of the first flame hole 31; a portion of the first flame hole 31 can be seen on the right side of the cross-section. The cross-sections of the first annular groove 3 and the first flame hole 31 are inclined from bottom to top in a direction away from the inner annular flame cap 10, forming a second inclination angle β, where α > β. Through the above arrangement, the first annular groove 3 can uniformly distribute the overflowing gas from the multiple first flame holes 31 and guide the overflowing gas, ensuring that α > β. That is, when the outlet of the first gas hole 52 is a certain distance from the top of the first annular groove 3, the air overflowing from the first gas hole 52 is closer to the root of the first inner annular flame. Wherein, 40° ≤ α ≤ 60°, and in this embodiment, α = 50°, β = 20°.
[0038] It should be noted that the opening area of the first flame hole 31 at the bottom of the first ring groove 3 is relatively large. Only a part of the connecting section is left at the bottom of the first ring groove 3 to ensure the overall connection of the inner ring flame cover 10. This setting can ensure that the overflow area of the gas is larger.
[0039] Optionally, see Figure 1 and Figure 2The inner ring fire cover 10 is further provided with a third ring groove 4 located outside the first ring groove 3, and a fourth fire hole 41 is formed in the groove bottom of the third ring groove 4, each fourth fire hole 41 is communicated with the first gas cavity 1, so that the gas outlet area of the gas is further increased, and the fourth fire hole 41 forms a second inner ring fire, and the oxygen of the second inner ring fire is supplied from the outside.
[0040] Optionally, referring to Figure 1 and Figure 2 , the inner ring fire cover 10 is further provided with a second fire hole 53, at least one first gas hole 52 is arranged between two adjacent second fire holes 53, and the second fire hole 53 and the first gas hole 52 are arranged in a staggered manner in the circumferential direction. In the embodiment, a convex portion 5 is formed in the inner side of the first ring groove 3, the gas outlets of the second fire hole 53 and the first gas hole 52 are located on the top of the convex portion 5, and are arranged alternately at the top of the convex portion 5, and the gas overflowing from the second fire hole 53 forms a third inner ring fire, so that the gas overflowing from the first gas hole 52 simultaneously supplies oxygen to the first inner ring fire and the third inner ring fire (because the first gas hole 52 is arranged on both sides of each second fire hole 53), which improves the gas overflow efficiency and ensures the oxygen supply of the two layers of inner ring fires, and ensures sufficient combustion. In another embodiment, two or more first gas holes 52 can be arranged between two adjacent second fire holes 53, which is not limited herein.
[0041] Optionally, because the first gas hole 52 simultaneously supplies oxygen to two layers of inner ring fires, the required oxygen supply amount is large, and the outlet area of the first gas hole 52 is larger than that of the first fire hole 31, so that the first inner ring fire and the third inner ring fire can be combusted sufficiently.
[0042] Optionally, as shown in Figure 1 , the inner side of the convex portion 5 is a slope 51, and a third fire hole 54 is formed in the convex portion 5, each third fire hole 54 is communicated with the first gas cavity 2, and the outlet of the third fire hole 54 is located on the slope 51. Through the above arrangement, a plurality of third fire holes 54 are arranged at the innermost side of the inner ring fire cover 10, and the third fire hole 54 is arranged from bottom to top towards the center of the inner ring fire cover 10 due to the arrangement of the slope 51, which improves the heating efficiency of the bottom center position of the to-be-heated vessel on the one hand, and the gas overflowing from the third fire hole 54 forms a fourth inner ring fire on the other hand, that is, there are four layers of inner ring fires from the outside to the inside in the embodiment, which greatly increases the gas overflow efficiency and improves the heating uniformity of the to-be-heated vessel.
[0043] Optionally, referring to Figures 1-3The inner ring fire cover 10 is provided with a circle of second air holes 61. The second air holes 61 are located on the side of the convex part 5 close to the center of the inner ring fire cover, and a circle of second air holes 61 are in communication with the first air supplementing cavity 2. The second air holes 61 are inclined from the bottom to the top away from the center of the inner ring fire cover 10. Through the above arrangement, the circle of second air holes 61 supply oxygen to the fourth inner ring fire. Since the top of the third fire hole 54 is inclined towards the center of the inner ring fire cover 10, and the top of the second air hole 61 is inclined away from the center of the inner ring fire cover 10, the top of the two is close to the trend, so that the gas overflowed from the second air hole 61 can be directly supplied to the root of the fourth inner ring fire, and the gas combustion is more sufficient.
[0044] Optionally, as shown in Figure 1 and Figure 2 , the inner side of the convex part 5 forms a second ring groove 6, and a circle of second air holes 61 are arranged on the groove bottom of the second ring groove 6. The second ring groove 6 and the second air hole 61 are inclined from the bottom to the top away from the center of the inner ring fire cover 10 to form a third inclination angle γ. The second ring groove 6 can play a uniform flow role for the overflow air of the plurality of second air holes 61, and play a guiding role for the overflow of the air.
[0045] Wherein, 10°≤γ≤30°, in the embodiment, γ=20°.
[0046] It can be understood that the outer side of the first inner ring fire formed by a circle of first fire holes 31 has the shielding of the second inner ring fire and the fourth inner ring fire on the inner side. In the prior art, the middle layer inner ring fire is not provided with an air supplement scheme, which leads to insufficient combustion of the middle layer inner ring fire. In the embodiment, the first inner ring fire is directly supplemented with air to the root of the first inner ring fire through the arrangement of a circle of first air holes 52, which ensures the sufficiency of the combustion of the middle layer inner ring fire in the multi-layer inner ring fire design scheme.
[0047] Optionally, as shown in Figure 1 , the second fire hole 53 and the third fire hole 54 are arranged one by one and share an air inlet. The open area of the top of the first gas cavity 1 can be reasonably utilized to avoid insufficient strength caused by too close spacing of the top openings of the first gas cavity 1.
[0048] Further, referring to Figure 3 , a plurality of thickened protrusions 9 are protruded on the lower side of the inner ring fire cover 10. The plurality of thickened protrusions 9 are arranged circumferentially in the first gas cavity 1. The second fire hole 53 and the third fire hole 54 are arranged on the thickened protrusions 9. Through the above arrangement, on the one hand, the support strength of the inner ring fire cover 10 can be improved, and on the other hand, when the second fire hole 53 and the third fire hole 54 are arranged, it is ensured that there is sufficient wall thickness outside the hole, and the open area of the top of the first gas cavity 1 is increased.
[0049] The embodiment provides a burner, as shown in Figure 4As shown, the burner comprises the inner ring fire cover 10 and the gas distribution disc 20; the gas distribution disc 20 is provided with the second gas cavity 21 and the second air supplement cavity 22 which are independent of each other, the second gas cavity 21 is located at the outer periphery of the second air supplement cavity 22, the inner ring fire cover 10 is buckled on the gas distribution disc 20, so that the first gas cavity 1 and the second gas cavity 21 form a gas cavity, and the first air supplement cavity 2 and the second air supplement cavity 22 form an air supplement cavity. The burner can make the gas combustion more sufficient, save energy and reduce cost, and improve safety by adopting the above-mentioned inner ring fire cover 10.
[0050] It can be understood that, in combination with Figure 1 and Figure 4 , the outer wall of the first gas cavity 1 is the first peripheral wall 7, the second peripheral wall 8 separates the first gas cavity 1 and the first air supplement cavity 2, the first peripheral wall 7 and the second peripheral wall 8 are buckled with the corresponding side walls of the gas distribution disc 20 respectively, so as to form the overall gas cavity and air supplement cavity.
