Description

Technical Field

[0001] This utility model belongs to the field of furnace core technology, specifically relating to an environmentally friendly furnace core for burning bio-alcohol oil. Background Technology

[0002] Environmentally friendly bio-ethanol oil is a new type of energy-saving and environmentally friendly fuel. It represents a new technological achievement in my country. Produced by fertilizer plants manufacturing nitrogen and ammonia using state-mandated methanol-exchange equipment, it is a flammable liquid produced by adding calorific value enhancers, modifiers, combustion improvers, oxidizers, stabilizers, smoke suppressants, and flavoring agents in specific proportions. It features no pressure, non-explosiveness, non-toxicity, an auto-ignition point of 385℃, and safe and reliable use. Currently, environmentally friendly bio-ethanol oil is mainly suitable for hot pot heating, fast food heat preservation, and grilled fish heat preservation.

[0003] In the field of environmentally friendly bio-ethanol combustion equipment, the furnace core, as a core functional component, directly determines the combustion efficiency, stability, and overall performance of the equipment through its structural design. Environmentally friendly bio-ethanol, as an environmentally friendly fuel, has been widely used in catering, industrial heating, and other fields in recent years due to its clean and renewable combustion products. However, its combustion characteristics differ significantly from traditional fuels, placing higher demands on the structural design of the furnace core. In existing technologies, the furnace core typically employs a structure combining a metal mesh and an outer shell, with the fuel supply and ignition functions separated through a partitioned design of the outer shell. While this design meets basic combustion requirements to some extent, it still reveals several technical bottlenecks in practical applications, urgently requiring solutions through innovative design. Existing environmentally friendly bio-ethanol fuel combustion furnace cores have significant defects in their fuel inlet structure. Many existing furnace cores have a sealed connection between the bottom surface of the outer shell and the bottom of the fuel chamber, severely hindering fuel from entering the furnace core. For example, in an environmentally friendly bio-ethanol fuel combustion furnace core disclosed in patent number CN115962495A, the bottom of the fuel inlet end forms a sealed structure with the bottom of the fuel chamber, preventing fuel from smoothly entering the furnace core. This results in the furnace core failing to burn properly due to insufficient fuel, affecting the normal operation of the environmentally friendly bio-ethanol fuel combustion equipment. In actual use, as fuel is consumed, the fuel level in the fuel chamber gradually decreases. However, due to the limitations of the fuel inlet structure, fuel at low levels cannot enter the furnace core to participate in combustion, resulting in fuel waste. This not only increases operating costs but also contradicts the development concept of energy conservation and emission reduction. Furthermore, to ensure the normal operation of the furnace core, users need to frequently add fuel, reducing the convenience and continuity of equipment use.

[0004] In summary, existing furnace cores for environmentally friendly bio-ethanol combustion have many problems in terms of oil inlet structure, and a new design is urgently needed to solve these technical problems in order to improve the performance and practicality of environmentally friendly bio-ethanol combustion equipment. Utility Model Content

[0005] The purpose of this utility model is to provide an environmentally friendly bio-alcohol fuel combustion furnace core to solve the problems of defects in the existing furnace core oil inlet structure, which lead to fuel not being able to enter the furnace core smoothly, not being able to fully utilize low-liquid-level fuel, and causing fuel waste.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An environmentally friendly bio-alcohol fuel combustion core is disposed in the fuel chamber of a combustion furnace. It includes an outer shell and a metal mesh attached to the inner wall of the outer shell. The bottom surface of the outer shell abuts against the bottom surface of the fuel chamber. The outer shell is vertically spaced with: an upper fuel inlet hole configured as an annular opening; and a lower fuel inlet hole configured as an open slot facing the bottom surface of the fuel chamber. The lower fuel inlet hole is positioned below the upper fuel inlet hole to prevent fuel accumulation in the fuel chamber. Furthermore, the lower and upper fuel inlets are staggered along the axial direction of the outer shell to prevent deformation during combustion. This fuel inlet structure ensures that fuel enters the combustion core smoothly regardless of fuel level, effectively avoiding combustion failure due to fuel shortage, improving fuel utilization, reducing operating costs, and enhancing the convenience and continuity of equipment use. The vertical staggered arrangement of the lower and upper fuel inlets prevents excessive fuel concentration upon entering the combustion core, thus avoiding damage to the structural strength of the outer shell during combustion.

[0007] Furthermore, at least one lower oil inlet hole is provided.

[0008] Furthermore, the metal mesh is fixed to the inner wall of the outer casing by welding and blocks the upper and lower oil inlet holes, which can filter impurities in the fuel.

[0009] Furthermore, the metal mesh is fixed to the inner wall of the outer casing by spot welding.

[0010] Furthermore, the metal mesh is attached to the inner wall of the outer casing by tension.

[0011] Furthermore, the metal mesh extends to the outside of the housing at the end furthest from the fuel chamber.

[0012] Furthermore, the metal mesh extends 1-3 cm beyond the outer shell.

[0013] Furthermore, at least one ignition port is provided at the end of the housing away from the fuel chamber.

[0014] Furthermore, the ignition port is configured to be opposite to the lower oil inlet port.

[0015] Furthermore, the housing is provided with at least one vent, which is located below the ignition port.

[0016] By adopting the above technical solution, the following beneficial effects can be achieved: This invention, by providing upper and lower oil inlets on the outer casing, ensures that fuel can smoothly enter the furnace core regardless of the fuel level. This design effectively avoids the problem of the furnace core failing to burn properly due to insufficient fuel, fully utilizes the fuel in the fuel chamber, especially fuel at low levels, thereby significantly improving fuel utilization and reducing operating costs.

[0017] Because the furnace core of this invention can fully utilize the fuel in the fuel chamber, it reduces the need for frequent refueling due to insufficient fuel, thereby improving the convenience and continuity of equipment use. This is especially important for environmentally friendly bio-alcohol combustion equipment that requires long-term continuous operation, as it can greatly improve work efficiency and user experience.

[0018] By positioning the lower oil inlet hole offset from the upper oil inlet hole, excessive concentration of fuel upon entering the furnace core is avoided, promoting more uniform fuel distribution within the furnace core. This uniform distribution allows for more thorough mixing of fuel with air, thereby improving combustion efficiency, reducing unburned fuel emissions, further enhancing the environmental performance of the environmentally friendly bio-alcohol combustion equipment, and preventing damage to the structural strength of the outer shell.

The components of the embodiments of this utility model described and shown in the accompanying drawings can be arranged and designed in various different configurations. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0027] Example 1: See Figures 1-4 This embodiment provides an environmentally friendly bio-ethanol oil combustion furnace core. The furnace core has a compact overall structure and a reasonable design, which can effectively solve the defects of the existing furnace core oil inlet structure and improve the performance and practicality of the environmentally friendly bio-ethanol oil combustion equipment.

[0028] See Figures 2-3 This embodiment of an environmentally friendly bio-ethanol fuel combustion furnace core mainly includes an outer shell 1 and a metal mesh 2 bonded to the inner wall of the outer shell 1. The outer shell 1 is the main structure of the furnace core, made of metal, with good thermal conductivity and structural strength, capable of withstanding the high temperatures generated during the combustion of environmentally friendly bio-ethanol fuel. The outer shell 1 is made of high-strength, high-temperature resistant alloy steel, which has good corrosion resistance and oxidation resistance, enabling it to work stably for a long time in high-temperature environments, thus extending the service life of the furnace core. The metal mesh 2 serves to filter and disperse fuel oil and assist combustion; its material is typically woven from high-temperature resistant and corrosion-resistant metal wires.

[0029] The outer casing 1 has an upper oil inlet hole 11 and a lower oil inlet hole 12 arranged vertically at intervals. The upper oil inlet hole 11 is configured as an annular opening. This annular opening design can increase the channel area for fuel to enter the furnace core, so that the fuel can enter the furnace core more smoothly when the liquid level is high.

[0030] The lower oil inlet 12 is configured as an open slot facing the bottom of the fuel chamber 3. The design of the open slot allows fuel to enter the furnace core smoothly even when the fuel level is low. When the fuel level in the fuel chamber 3 drops below the upper oil inlet 11, the open slot can contact the fuel at the low level, ensuring a continuous supply of fuel to the furnace core and effectively preventing liquid accumulation in the fuel chamber 3.

[0031] The lower oil inlet 12 is positioned below the upper oil inlet 11. This vertical arrangement fully utilizes the space within the fuel chamber 3 and can accommodate fuel supply needs at different liquid levels. Furthermore, the lower oil inlet 12 and the upper oil inlet 11 are staggered along the axial direction of the outer shell 1. This staggered arrangement has several important implications. Firstly, it prevents fuel from concentrating too much when entering the furnace core, allowing for a relatively uniform distribution of fuel within the furnace core. If the oil inlets are concentrated, the fuel may form a higher concentration in localized areas after entering the furnace core, leading to uneven combustion and reducing the structural strength of the outer shell 1. In some cases, excessively high local temperatures could even damage the structural strength of the outer shell 1. Through this staggered arrangement, the fuel mixes better with air after entering the furnace core, improving combustion efficiency, reducing unburned fuel emissions, and further enhancing the environmental performance of the environmentally friendly bio-ethanol combustion equipment. Secondly, the staggered arrangement also helps reduce deformation of the outer shell 1 during combustion due to uneven heating in certain areas, extending the service life of the furnace core.

[0032] In this embodiment, two lower oil inlet holes 12 are configured, evenly distributed on the side of the outer shell 1. The design of two lower oil inlet holes 12 further increases the number of channels for fuel to enter the furnace core, improving the stability and reliability of fuel supply. Even if one of the lower oil inlet holes 12 fails for some reason (such as blockage by impurities), the other lower oil inlet hole 12 can still ensure the normal supply of fuel and ensure the normal operation of the furnace core.

[0033] The upper oil inlet 11 and the lower oil inlet 12 are not in the same vertical direction to avoid damaging the structural strength of the outer shell 1 during combustion. A fuel passage is formed between the lower oil inlet 12 and the bottom of the fuel chamber 3, and this fuel passage is located below the upper oil inlet 11. Regardless of the fuel level, fuel can be smoothly introduced into the furnace core. When the fuel level is higher than the upper oil inlet 11, fuel can enter the furnace core through both the upper oil inlet 11 and the lower oil inlet 12; when the fuel level is lower than the upper oil inlet 11, fuel can enter the furnace core through the lower oil inlet 12. The bottom surface of the outer shell 1 is not blocked from entering the furnace core by contact with the bottom of the fuel chamber 3, thus making full use of the fuel in the fuel chamber 3, especially the fuel at low levels.

[0034] In this embodiment, the end of the metal mesh 2 furthest from the fuel chamber 3 extends outside the outer casing 1, exceeding the casing 1 by 3 cm. Ignition can be performed directly on the metal mesh extending beyond the casing 1. This design helps increase the contact area with air, thus improving the ignition success rate.

[0035] See Figure 4Alternatively, an ignition port 13 can be provided at the end of the outer casing 1 away from the fuel chamber 3. The outer casing 1 is provided with at least one ignition port 13, which is configured to be opposite to the lower oil inlet port 12. This configuration allows the fuel to quickly come into contact with the flame generated by the ignition port 13 after entering the furnace core, achieving rapid ignition.

[0036] Multiple vents 14 are provided on the side wall of the outer casing 1, located below the ignition port 13. The vents 14 are circular or similar and are evenly distributed on the outer casing 1. The function of the vents 14 is to provide sufficient air for combustion, ensuring that the environmentally friendly bio-ethanol oil can burn completely, improving combustion efficiency, and reducing the emission of harmful gases.

[0037] The metal mesh 2 is fixed to the inner wall of the outer shell 1 by spot welding. Spot welding is an efficient and reliable welding method that ensures a tight bond between the metal mesh 2 and the outer shell 1, preventing it from easily falling off. During the welding process, specialized spot welding equipment is used to control the welding current and welding time, ensuring welding quality. The number and distribution of spot welds are rationally designed based on the size and material of the metal mesh 2. Through spot welding, the metal mesh 2 is not only firmly bonded to the inner wall of the outer shell 1, but also effectively blocks the upper oil inlet 11 and the lower oil inlet 12, filtering impurities in the fuel oil, preventing pollution from the combustion of impurities, ensuring the cleanliness of the fuel oil entering the furnace core, and improving combustion quality.

[0038] Alternatively, the metal mesh 2 can also be attached to the inner wall of the outer casing 1 using tension bonding. When installing the metal mesh 2, it is first cut to a suitable size, then fitted onto the inner wall of the outer casing 1. The tension of the metal mesh 2 itself ensures a tight fit to the inner wall of the outer casing 1. This fixing method eliminates the need for welding, avoiding potential thermal deformation and damage to the metal mesh 2 material during welding, thus guaranteeing the integrity and performance of the metal mesh 2. Tension bonding makes the metal mesh 2 adhere more tightly to the outer casing 1 and facilitates disassembly and replacement.

[0039] See Figures 1-4 When using the environmentally friendly bio-ethanol oil combustion furnace core of this embodiment, the furnace core is installed inside the fuel chamber 3 of the environmentally friendly bio-ethanol oil combustion device. When the level of the environmentally friendly bio-ethanol oil in the fuel chamber 3 is higher than the upper fuel inlet 11, fuel enters the furnace core through the upper fuel inlet 11 and the lower fuel inlet 12. The metal mesh 2 extends 1-3 cm beyond the outer shell, allowing the fuel and air to mix thoroughly. The ignition device generates a flame, igniting the mixed fuel and air to achieve combustion. When the fuel level is lower than the upper fuel inlet 11, fuel enters the furnace core through the lower fuel inlet 12, continuing to provide fuel for combustion.

[0040] In another embodiment, an ignition port 13 is provided at the end of the outer casing 1 furthest from the fuel chamber 3. Since the lower fuel inlet 12 is positioned opposite the ignition port 13, the fuel can quickly come into contact with the flame, ensuring continuous combustion. Simultaneously, air enters the furnace core through the vent 14 on the side wall of the outer casing 1, where it mixes thoroughly with the fuel. The ignition device generates a flame, igniting the mixed fuel and air to achieve combustion.

[0041] This embodiment of an environmentally friendly bio-ethanol fuel combustion furnace core utilizes a unique fuel inlet structure design to ensure smooth fuel entry into the furnace core regardless of fuel level, effectively preventing combustion failure due to insufficient fuel. Simultaneously, it fully utilizes the fuel in the fuel chamber 3, especially at low levels, significantly improving fuel efficiency and reducing operating costs. By reducing the need for frequent fuel replenishment, it enhances the convenience and continuity of equipment use, which is particularly important for environmentally friendly bio-ethanol fuel combustion equipment requiring long-term continuous operation. Furthermore, by spaced the lower fuel inlet 12 and the upper fuel inlet 11, it prevents excessive concentration of fuel upon entering the furnace core, promoting uniform fuel distribution, improving combustion efficiency, reducing unburned fuel emissions, and further enhancing the environmental performance of the bio-ethanol fuel combustion equipment.

[0042] In summary, the environmentally friendly bio-ethanol fuel cell core of this utility model, through the design and improvement of various embodiments, effectively solves the defects of the fuel cell inlet structure in the prior art, improves the utilization rate of fuel, the convenience and continuity of the equipment, the combustion efficiency and environmental performance, and has significant technical advantages and market application prospects.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
