Description

Technical Field

[0001] This application relates to the field of stoves, and more specifically, to a combustion furnace inner liner structure. Background Technology

[0002] The furnace shell of existing combustion furnaces usually adopts an inverted cone-shaped structure at the top to concentrate the flame. At the same time, the inverted cone-shaped structure usually has multiple through holes for air intake. Because the furnace shell wall is thin, the air cannot be guided when it enters directly through the through holes, resulting in turbulence that blows the flame and causes unstable flame combustion.

[0003] Therefore, a combustion furnace inner liner structure is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a combustion furnace inner liner structure, including: a cylindrical portion and an inverted funnel portion. The funnel portion has an opening at the upper end of the cylindrical portion and a funnel portion axis. Circumferentially distributed strip-shaped reinforcing ribs are provided on the inner side of the funnel portion. Through holes are formed on the strip-shaped reinforcing ribs, and the through holes have through hole axes. Adjacent strip-shaped reinforcing ribs cooperate with the inner wall of the funnel to form a flow channel, which is used for guidance, allowing the flame to rotate and escape from the opening. The through holes penetrate the strip-shaped reinforcing ribs and extend to the outer side of the funnel portion at one end. A circle is drawn on a horizontal plane with the point projected onto the funnel portion axis as the center, and the projection of the through hole axis onto the horizontal plane is tangent to this circle. The flow direction of air entering the inner liner through multiple through holes is the same as the flow direction of the flame escaping from the opening of the funnel portion.

[0006] By incorporating reinforcing ribs and through holes, the reinforcing ribs enhance the overall strength of the inner liner while ensuring the length of the through holes. This allows air to flow within the through holes in a guided manner, ensuring that the airflow into the inner liner is directed in a specific direction and preventing turbulence. Furthermore, the formation of flow channels guides the flame, which then rotates and bursts out from the opening of the cylindrical section.

[0007] Furthermore, multiple sets of boss structures are provided on the outer wall of the funnel section. One end of the through hole forms an opening on the strip reinforcing rib, and the other end extends to the boss and forms an opening on the surface of the boss structure. Air passes through the through hole, through the boss and the strip reinforcing rib, and enters the inner liner.

[0008] By setting up a boss structure, the through hole forms an opening on the surface of the boss, allowing air to enter the inner liner through the opening on the boss. The boss ensures the length of the through hole and guides the air.

[0009] Furthermore, the strip-shaped reinforcing ribs extend spirally upward along the inner wall of the funnel, so that the flow channel formed by two adjacent strip-shaped reinforcing ribs and the inner wall of the funnel also extends spirally upward. The spiral direction of the flow channel is the same as the spiral direction of the air entering the inner liner through the through hole.

[0010] By extending the reinforcing ribs along a spiral, the flame inside the liner is ejected from the opening at the funnel in a rotating manner under the action of the flow channel, ensuring the stability of the flame combustion. At the same time, the air introduced through the through hole further propels the flame to rotate.

[0011] Furthermore, the strip-shaped reinforcing rib is provided with multiple through holes, which are arranged along the extension direction of the strip-shaped reinforcing rib.

[0012] Furthermore, the through-hole axis is arranged at an angle, pointing towards the upper opening of the funnel section.

[0013] The opening, with its axis pointing upwards towards the top of the funnel, allows air to enter the inner liner and propel the flame upwards, ensuring optimal combustion.

[0014] Furthermore, the number of bosses is the same as the number of through holes.

[0015] The beneficial effects of this application are as follows:

[0016] 1. By setting reinforcing ribs and through holes, the reinforcing ribs improve the overall strength of the inner liner while ensuring the length of the through holes, so that the air can be guided during the flow of the through holes, and thus the air flowing into the inner liner can flow in a certain direction to avoid turbulence.

[0017] 2. By setting reinforcing ribs and bosses, the traditional furnace core cannot be machined with through holes at a certain angle due to its thin wall thickness and smooth surface.

[0018] 3. Air enters the furnace chamber through the through hole, which in turn blows the flame, causing it to rotate and burn, thus improving combustion stability.

[0019] 4. By extending the reinforcing ribs along a spiral, the flame in the inner liner is made to rotate under the action of the flow channel, further ensuring the stability of the flame combustion. At the same time, the air introduced through the through hole further propels the flame to rotate. Attached Figure Description

[0034] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Reference Figures 1-5 A combustion furnace inner liner structure includes: a cylindrical portion 100, a funnel portion 101, strip-shaped reinforcing ribs 102, a through hole 103, a through hole axis 104, a funnel portion axis 105, and a boss 106. The inner liner body is composed of the cylindrical portion 100 and the funnel portion 101. The inverted funnel portion 101 is located at the upper end of the cylindrical portion 100 and has an opening at the center of the upper end. The strip-shaped reinforcing ribs 102 are fixedly disposed on the inner wall of the funnel portion 101. The through hole 103 is disposed on the strip-shaped reinforcing ribs 102 and penetrates the strip-shaped reinforcing ribs 102 and the side wall of the funnel portion 101. Multiple strip-shaped reinforcing ribs 102 are provided and arranged circumferentially on the inner wall of the funnel portion 101. The boss 106 is disposed on the outer wall of the funnel portion 101. One end of the through hole 103 forms an opening in the strip-shaped reinforcing rib 102, and the other end extends to the boss 106 and forms an opening on the structural surface. The number of bosses 106 is the same as the number of through holes 103.

[0036] Reference Figures 1-2 In one embodiment, the reinforcing ribs 102 extend spirally along the inner wall of the funnel portion 101. Two adjacent reinforcing ribs 102 form a flow channel with the inner wall of the funnel portion 101. Because the reinforcing ribs 102 are spirally arranged, the flow channel is also spirally arranged, causing the flame to rotate after being guided by the flow channel and then spirally exit from the opening of the funnel portion 101. In another embodiment, the reinforcing ribs 102 are inclinedly arranged on the inner wall of the funnel portion 101. In this case, the flow channel is also inclined, causing the flame to rotate after being guided by the flow channel.

[0037] Reference Figure 2 In one embodiment, a strip-shaped reinforcing rib 102 has multiple through holes 103. A circle is drawn on a horizontal plane with the point projected onto the axis 105 of the funnel portion as its center, and the projection of the through hole axis 104 onto the horizontal plane is tangent to this circle. This causes the air entering the furnace through the through holes 103 to rotate and flow within the furnace under the action of the inner wall of the furnace, thus driving the flame to rotate.

[0038] Reference Figure 3In one embodiment of this invention, the through-hole axes 104 on the same strip-shaped reinforcing rib 102 are parallel to each other and are arranged horizontally.

[0039] Reference Figure 4 In one embodiment of this invention, the through-hole axes 104 on the same reinforcing rib 102 are parallel to each other, and the through-hole axes 104 are arranged at an angle, pointing towards the upper opening of the funnel portion 101. At this time, when air enters the furnace, it can both rotate and flow upward, thereby driving the flame to rotate and rise upward, ensuring the combustion effect.

[0040] Reference Figure 5 In one embodiment, the boss 106 is configured as a frustum structure coaxial with the through hole 103, and the openings formed on the boss 106 by the through hole 103 are radially distributed around the axis 105 of the funnel portion.

[0041] In one embodiment, the boss 106 is configured as a square platform, and the opening formed by the through hole 103 on the boss 106 is located on one side of the square platform.

[0042] Working process or usage method:

[0043] When the flame burns inside the furnace, guided by the strip-shaped reinforcing rib 102, the flame burns and rotates upward along the flow channel. Air enters the furnace from the opening at the upper end of the boss 106 and is guided by the through hole 103, causing the air flow to drive the flame to rotate.

[0044] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
