Description

Technical Field

[0001] This utility model relates to the field of burner equipment technology, and more specifically, to a burner nozzle for a hopper-type open furnace. Background Technology

[0002] The ring-type open furnace is a widely used industrial furnace type for metal heat treatment (such as quenching, tempering, and annealing). Its key feature is that the furnace body is movable or open, facilitating the transfer of workpieces (placed in a specially designed hopper) into or out of the furnace for heating via hoisting equipment. In this type of furnace, the burner nozzle is the core heating element, and its performance directly determines the uniformity of the temperature field within the furnace, heating efficiency, and the final product quality.

[0003] However, existing burner nozzles have some drawbacks: 1. Conventional nozzles mostly use direct injection or simple conical diffusion structures, resulting in insufficient mixing of fuel and air, which easily leads to incomplete combustion, poor flame rigidity, and instability. This not only reduces combustion efficiency and wastes fuel, but also causes uneven heating of the fuel tank due to the formation of local high or low temperature zones, affecting the quality of heat treatment. Incomplete combustion also produces a large amount of pollutants such as carbon deposits and nitrogen oxides, making it difficult to meet the increasingly stringent environmental protection requirements. 2. Since the nozzles work in a high-temperature, carbon-deposited environment for a long time, they need to be cleaned or replaced regularly. However, traditional nozzles mostly use bolt fastening and other fixing methods, which makes the disassembly and assembly process cumbersome, time-consuming, and labor-intensive, resulting in long equipment maintenance downtime, which seriously affects the continuity of industrial production and economic benefits.

[0004] Therefore, there is an urgent need for a burner nozzle for a ring-shaped open furnace to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a burner nozzle for a hopper-type open furnace to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: A burner nozzle for a hopper-type open furnace includes a mounting base and further includes: An air intake seat is disposed on the top of the mounting base, and a fire channel cover is disposed on the top of the air intake seat. The fire channel cover, the air intake seat, and the mounting base are interconnected. The fixed sleeve is installed on the top of the fire duct cover via a quick-release assembly; A tapered sleeve is mounted on the inner wall of a fixed sleeve via a sliding assembly, and an adjusting seat B is fixedly connected to the side wall of the tapered sleeve. Traffic diversion components, including: The outer spiral connecting plate is uniformly and fixedly connected to the inner wall of the tapered sleeve; A spiral hollow tube is fixedly connected to the side wall of the outer spiral connecting plate; The inner spiral connecting plate is fixedly connected to the side of the spiral hollow tube away from the outer spiral connecting plate; A conical guide tube is fixedly connected to the side wall of the inner spiral connecting plate, and both the conical guide tube and the spiral hollow tube have a bottom inlet larger than the top outlet.

[0007] As a preferred technical solution of this application, the quick-release component includes: Guide blocks are evenly and fixedly connected to the top wall of the fire duct cover; The ferrule is slidably connected to the outer wall of the guide block; A strong tension spring, one end of which is fixedly connected to the top wall of the guide block, and the other end is fixedly connected to the sleeve, and the strong tension spring is symmetrically arranged about the guide block; The card holder is slidably connected to the outer wall of the card sleeve through a card slot formed on the side wall of the card holder.

[0008] As a preferred technical solution of this application, the sliding component includes: Adjustment grooves are evenly distributed on the inner wall of the fixed sleeve; A sliding block is slidably connected to the inner wall of the adjusting groove, and the sliding block is fixedly connected to the tapered sleeve.

[0009] As a preferred technical solution of this application, the tapered sleeve sidewall is fixedly connected to an adjusting seat A, the outer wall of the adjusting seat A is rotatably connected to an adjusting screw, and the adjusting screw is threadedly connected to the adjusting seat B.

[0010] As a preferred technical solution of this application, a combustion nozzle is fixedly connected to the top of the conical sleeve, and the combustion nozzle is connected to the conical guide tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By using a spiral tapering guide assembly to force gas rotation and centrifugal action, the fuel and air are fully and uniformly mixed at the molecular level, resulting in more complete combustion, significantly improving combustion efficiency, saving fuel, and reducing carbon deposits or harmful gas emissions caused by uneven mixing. At the same time, the spiral structure of the inner and outer spiral connecting plates allows the high-speed rotating airflow to form a stable central recirculation zone at the nozzle, anchoring the flame root, preventing flameout or pulsation, and giving the flame extremely strong rigidity and penetrating power, so that it is not disturbed by turbulence in the furnace and can penetrate deep into the furnace, ensuring uniform heating of the fuel box. This solves the problems of poor combustion performance, uneven fuel-air mixing, incomplete combustion, high energy consumption, high pollution, and insufficient flame stability affecting heating uniformity in existing technologies. 2. The quick-release components make the disassembly and installation of core components exceptionally fast, greatly reducing downtime for maintenance, cleaning, or nozzle replacement. For industrial furnaces that require frequent maintenance, this significantly improves equipment utilization and production efficiency, solving the problems of poor maintenance convenience, low disassembly efficiency of traditional connection methods, long maintenance cycles, and serious impact on equipment utilization and economic benefits in existing technologies.

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0015] like Figure 1-5 As shown, the burner nozzle for a hopper-type open furnace proposed in this embodiment includes a mounting base 1, and further includes: Air intake seat 2 is located on top of mounting base 1, and fire channel cover 3 is provided on top of air intake seat 2. Fire channel cover 3, air intake seat 2 and mounting base 1 are interconnected. The fixed sleeve 4 is installed on the top of the fire channel cover 3 via a quick-release assembly; The tapered sleeve 7 is mounted on the inner wall of the fixed sleeve 4 via a sliding assembly, and an adjusting seat B19 is fixedly connected to the side wall of the tapered sleeve 7. Traffic diversion components, including: The outer spiral connecting plate 17 is uniformly and fixedly connected to the inner wall of the tapered sleeve 7; The spiral hollow tube 16 is fixedly connected to the side wall of the outer spiral connecting plate 17; The inner spiral connecting plate 15 is fixedly connected to the side of the spiral hollow tube 16 away from the outer spiral connecting plate 17; The conical guide tube 14 is fixedly connected to the side wall of the inner spiral connecting plate 15. Both the conical guide tube 14 and the spiral hollow tube 16 have a bottom inlet larger than the top outlet. The mixed gas then enters the core guide assembly composed of the conical guide tube 14, the inner spiral connecting plate 15, the spiral hollow tube 16, and the outer spiral connecting plate 17. This assembly forms a spiral converging channel with a large inlet and a small outlet. The gas is forced to rotate and move forward at high speed along this channel, generating a strong centrifugal effect to achieve the ultimate uniform mixing of fuel and air. At the same time, the converging structure of the channel compresses the airflow, further increasing its velocity. The fully mixed and accelerated airflow is ejected from the top outlet of the conical guide tube 14 and enters the combustion nozzle 13. At this time, the airflow has extremely high kinetic energy and rotational speed. After being ignited at the nozzle, it forms a rotating flame with strong rigidity, stable shape, and sufficient penetrating power.

[0016] like Figure 2-3 As shown, in a preferred embodiment, based on the above method, the quick-release component further includes: Guide blocks 8 are evenly and fixedly connected to the top wall of the fire channel cover 3; The sleeve 10 is slidably connected to the outer wall of the guide block 8; A strong tension spring 9 is fixedly connected at one end to the top wall of the guide block 8 and at the other end to the sleeve 10. The strong tension spring 9 is symmetrically arranged about the guide block 8. The card holder 11 is slidably connected to the outer wall of the sleeve 10 through the card slot 12 opened on the side wall of the card holder 11. When maintenance is required, the sleeve 10 can be moved by overcoming the pulling force of the strong tension spring 9, so that it is disengaged from the card slot 12 of the card holder 11. The entire fixed sleeve 4 and above components can be quickly removed from the fire channel cover 3 for easy cleaning or replacement of internal components.

[0017] like Figure 2 As shown, in a preferred embodiment, based on the above method, the sliding component further includes: Adjustment grooves 5 are evenly distributed on the inner wall of the fixed sleeve 4; The sliding block 6 is slidably connected to the inner wall of the adjusting groove 5, and the sliding block 6 is fixedly connected to the tapered sleeve 7. The flow guiding component slides up and down along the sliding block 6 in the adjusting groove 5.

[0018] like Figure 1 As shown, in a preferred embodiment, based on the above method, an adjusting seat A18 is fixedly connected to the side wall of the conical sleeve 7. An adjusting screw 20 is rotatably connected to the outer wall of the adjusting seat A18, and the adjusting screw 20 is threadedly connected to the adjusting seat B19. By rotating the adjusting screw 20, the adjusting seat B19 can be driven, thereby causing the entire conical sleeve 7 and its internal flow guiding assembly to slide up and down along the sliding block 6 in the adjusting groove 5. This changes the relative position and gap between the top of the conical flow guiding tube 14 and the combustion nozzle 13, which is equivalent to adjusting the size of the final nozzle, thereby achieving precise control of the flame shape, length and spray speed.

[0019] like Figure 2 As shown, in a preferred embodiment, based on the above method, a combustion nozzle 13 is fixedly connected to the top of the conical sleeve 7, and the combustion nozzle 13 is connected to the conical guide tube 14, so that flames are sprayed into the box through the combustion nozzle 13.

[0020] Specifically, in use, the burner nozzle of this ring-type open furnace operates as follows: the fuel-air mixture enters from the bottom, flows through the mounting base 1 and the air inlet seat 2, and finally reaches the fire channel cover 3 area, completing the initial mixing; the mixed gas then enters the core guiding assembly composed of a conical guide tube 14, an inner spiral connecting plate 15, a spiral hollow tube 16, and an outer spiral connecting plate 17. This assembly forms a spirally converging channel with a large inlet and a small outlet. The gas is forced to rotate at high speed along this channel, generating a strong centrifugal effect, achieving the ultimate uniform mixing of fuel and air. At the same time, the converging structure of the channel compresses the airflow, further increasing its velocity. After being fully mixed and accelerated, the airflow exits from the top outlet of the conical guide tube 14 and enters the combustion nozzle 13. At this time, the airflow has extremely high kinetic energy and rotation speed. After being ignited at the nozzle, it forms a rotating flame with strong rigidity, stable shape, and sufficient penetrating power. By rotating the adjusting screw 20, the adjusting seat B19 can be driven, thereby causing the entire conical sleeve 7 and its internal flow guiding components to slide up and down in the adjusting groove 5 along the sliding block 6. This changes the relative position and gap between the top of the conical flow guiding tube 14 and the combustion nozzle 13, which is equivalent to adjusting the size of the final nozzle, thus achieving precise control over the flame shape, length, and spray speed. When maintenance is required, by operating the strong tension spring 9 to move the clamp 10, it can be disengaged from the clamp groove 12 of the clamp seat 11, allowing the entire fixed sleeve 4 and the components above it to be quickly removed from the fire channel cover 3 for easy cleaning or replacement of internal components.

[0021] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
