Description

Technical Field

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

[0002] A burner is a key device that precisely controls the injection and mixing of fuel and air in a specific manner for combustion. During operation, fuel and air are introduced into the combustion zone according to a predetermined path and ratio to achieve efficient and stable combustion. Structurally, a burner mainly consists of a burner head, combustion chamber, ignition device, and air regulator. The burner head is responsible for precisely injecting fuel and air to ensure their full mixing; the combustion chamber provides a stable combustion space, helping to improve combustion efficiency; the ignition device releases energy to ignite the mixture; and the air regulator flexibly adjusts the air intake as needed, precisely controlling the combustion intensity and stability. Burners are classified in many ways; according to fuel type, they can be divided into... Oil, gas, and biomass burners; based on combustion control methods, there are proportional control, two-stage, and pulse burners; based on fuel atomization methods, there are pressure atomization and medium atomization burners; based on structural form, there are integrated and split burners. When burners are used in boilers, vegetable oil fuel has significant advantages. Vegetable oil fuel is liquid under normal conditions, is not easily combustible, and is not prone to leakage during storage and transportation, greatly reducing the risk of explosion. The combustion process is stable, easy to extinguish, and has high safety. Due to its high oxygen content, it can burn completely, has excellent thermal efficiency, and can achieve good heating effect with less fuel, reducing energy consumption and operating costs. In addition, vegetable oil fuel has a flash point between 160℃ and 300℃, and is difficult to ignite at room temperature, greatly reducing the risk of fire and reducing special protection costs, thus balancing safety and economic benefits.

[0003] When a burner is in use, the burner head is inserted into the boiler, and then the burner is started to heat the boiler. However, when the burner head is inserted into the boiler, there is a gap between the burner head and the boiler. As a result, some heat will leak out from the gap during use, causing some heat waste. Therefore, this application provides an energy-saving burner to meet this need. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an energy-saving burner to solve the problem of heat waste caused by the gap between the burner head and the boiler.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An energy-saving burner includes a burner body and a burner head installed at the end of the burner body, and further includes:

[0007] A sealing mechanism includes a retaining ring, which is detachably connected to the outer circumferential surface of the burner head. A sealing ring is fixed on the side of the retaining ring away from the burner body, and the sealing ring is movably sleeved on the outer circumferential surface of the burner head.

[0008] Preferably, the outer circumferential surface of the sealing ring is provided with a groove, and a horizontal part is provided in the groove near the combustion head.

[0009] Preferably, a plurality of circular tubes are embedded in the side of the sealing ring near the retaining ring. The circular tubes are fixed to the side of the retaining ring. An expansion cavity is opened inside the sealing ring and is connected to the circular tubes. A heat-conducting tube is fixedly inserted through the end of the circular tube. A part of the heat-conducting tube is located inside the sealing ring and a part extends out of the sealing ring and is located in the groove. A thermal expansion tube is fixed to the side of the inner wall of the circular tube near the heat-conducting tube. The heat-conducting tube is fixed to the end of the thermal expansion tube. A piston is fixed to the end of the thermal expansion tube. The space in the circular tube on the side of the piston away from the thermal expansion tube is filled with hydraulic oil.

[0010] Preferably, the surface of the circular tube is fixed with a plurality of circular rings, the circular rings being spaced at the same intervals, and the circular rings being disposed inside a sealing ring.

[0011] Preferably, the ring has a fixing hole on its side to improve the connection strength with the sealing ring.

[0012] Preferably, a control assembly is provided at the piston. The control assembly includes an L-shaped connecting rod fixed to the end of the piston. The surface of the L-shaped connecting rod is movably connected to the inner wall of the thermal expansion tube and the inner wall of the heat conduction tube. A first circular hole is provided at the horizontal part, and a second circular hole is provided on the burner head. The first and second circular holes are connected. A sealing plate is fixed to the bottom of the short side of the L-shaped connecting rod. The sealing plate is attached to the horizontal part to block the first circular hole.

[0013] Preferably, the end of the sealing ring near the retaining ring is provided with a protrusion.

[0014] Preferably, the sealing plate is a rubber plate, and the edges of the sealing plate are provided with arc-shaped chamfers.

[0015] Preferably, a barrier ring is fixed to the end of the sealing ring, and the barrier ring is sleeved on the outer circumferential surface of the burner head.

[0016] Preferably, the end of the barrier ring is provided with a guide surface.

[0017] Compared with the prior art, this utility model has at least the following beneficial effects:

[0018] In the above scheme, by setting a retaining ring and a sealing ring, after the burner head is inserted into the boiler, the sealing ring can fill the gap between the burner head and the boiler, thereby preventing heat from flowing out from the gap.

[0019] By setting a groove, when some hot air flows in from the sealing ring, the hot air will fill the groove. When the pressure inside the groove increases, the hot air will be unable to enter the groove, further preventing heat from flowing out.

[0020] By setting up a thermal expansion tube, piston, heat conduction tube, and expansion chamber, when hot gas is stored in the groove, the hot gas can heat the heat conduction tube, which can then conduct heat to the thermal expansion tube. After being heated, the thermal expansion tube can expand and deform, which will drive the piston to move. After the piston moves, the hydraulic oil in the round tube will enter the expansion chamber, increasing the pressure in the expansion chamber and causing the sealing ring to expand, thus improving the sealing performance between the sealing ring and the filter and preventing heat from being dissipated.

[0021] By setting up control components, the piston can drive the L-shaped connecting rod to move during its movement. The L-shaped connecting rod will then drive the sealing plate to move. The sealing plate will move away from one of the round holes. Since the burner body is in use, there is high-speed gas flowing through the burner head. At this time, the pressure of the burner head is lower than the pressure at the groove. Therefore, the hot gas in the groove will flow out from round holes one and two, and the hot gas will re-enter the burner head to mix with the gas, further avoiding heat waste.

[0030] The present invention provides an energy-saving burner in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0032] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense.

[0033] like Figures 1-5 As shown, an embodiment of this utility model provides an energy-saving burner, including a burner body 1 and a burner head 2 installed at the end of the burner body 1, and further including:

[0034] The sealing mechanism 3 includes a retaining ring 4, which is detachably connected to the outer circumferential surface of the burner head 2. A sealing ring 5 is fixed on the side of the retaining ring 4 away from the burner body 1. The sealing ring 5 is movably sleeved on the outer circumferential surface of the burner head 2. In boiler applications, there is often a gap between the burner head 2 and the boiler, which leads to heat loss. The detachable connection of the retaining ring 4 to the outer circumferential surface of the burner head 2 facilitates installation and subsequent maintenance and replacement. The movable sleeve of the sealing ring 5 on the burner head 2 allows it to flexibly adapt to the shape of the boiler interface when the burner head 2 is inserted into the boiler, filling the gap and effectively preventing heat loss from the gap between the burner head 2 and the boiler, thereby improving the thermal efficiency of the burner and reducing energy waste.

[0035] like Figure 3 As shown, in this embodiment, a groove 8 is provided on the outer circumferential surface of the sealing ring 5. A horizontal part 9 is provided near the burner head 2 in the groove 8. When hot gas leaks from the gap between the burner head 2 and the boiler to the sealing ring 5, the groove 8 can serve as a temporary storage space for the hot gas. As the hot gas continues to flow in, the pressure inside the groove 8 gradually increases, creating resistance to the entry of subsequent hot gas and further preventing heat leakage. The horizontal part 9 provides a stable distribution area for the hot gas in the groove 8, preventing the hot gas from running around randomly. On the other hand, the horizontal part 9 provides a basic structure for the installation and operation of the subsequent control component 17, which helps to realize the function of heat recovery.

[0036] like Figures 3-5 As shown, in this embodiment, a plurality of circular tubes 10 are embedded in the side of the sealing ring 5 near the retaining ring 4. The circular tubes 10 are fixed to the side of the retaining ring 4. An expansion cavity 15 is provided inside the sealing ring 5, and the expansion cavity 15 is connected to the circular tubes 10. A heat-conducting tube 14 is fixedly inserted through the end of the circular tube 10. A part of the heat-conducting tube 14 is located inside the sealing ring 5, and a part extends out of the sealing ring 5 and is located in the groove 8. A thermal expansion tube 12 is fixed to the inner wall of the circular tube 10 near the heat-conducting tube 14. The heat-conducting tube 14 is fixed to the end of the thermal expansion tube 12. A piston 13 is fixed to the end of the thermal expansion tube 12. The piston 13 is away from the thermal expansion tube 12. The space within the circular tube 10 on one side of tube 12 is filled with hydraulic oil. The hot air accumulated in the groove 8 has a high temperature. The heat conduction tube 14 can conduct this heat to the thermal expansion tube 12. After being heated, the thermal expansion tube 12 expands and deforms, pushing the piston 13 to move. The movement of the piston 13 causes the hydraulic oil in the circular tube 10 to flow into the expansion chamber 15, causing the sealing ring 5 to expand. In this way, the seal between the sealing ring 5 and the boiler is tighter, further reducing heat leakage to the outside. This design utilizes the heat of the hot air to achieve automatic adjustment of the sealing effect, enhances the sealing performance of the burner under different operating conditions, and improves the energy-saving effect.

[0037] like Figure 5As shown, in this embodiment, a plurality of rings 11 are fixed on the surface of the circular tube 10. The spacing between the rings 11 is the same. The rings 11 are set inside the sealing ring 5. Because the sealing ring 5 is provided with annular grooves, the rings 11 are engaged in the annular grooves, which improves the tightness and stability of the circular tube 10 and the sealing ring 5, making the fixing of the circular tube 10 in the sealing ring 5 more stable. During the process of the sealing ring 5 expanding due to the flow of hydraulic oil into the expansion chamber 15, the rings 11 help to evenly distribute the pressure, ensuring the uniformity of the expansion of the sealing ring 5, thereby improving the sealing performance when the sealing ring 5 contacts the boiler, and avoiding heat leakage problems caused by poor local sealing.

[0038] like Figure 5 As shown in this embodiment, a fixing hole is provided on the side of the ring 11 to improve the connection strength between it and the sealing ring 5. The fixing hole further enhances the connection between the ring 11 and the sealing ring 5. During the operation of the burner, especially under complex conditions such as high temperature and high pressure, the sealing ring 5 will be subjected to certain pressure and vibration. The presence of the fixing hole allows the material of the sealing ring 5 to be embedded in it, forming a stronger anchoring effect, preventing the ring 11 from shifting or loosening within the sealing ring 5, ensuring a stable connection between the circular tube 10 and the sealing ring 5, and ensuring the reliable operation of the entire thermal response sealing adjustment system.

[0039] like Figure 4 As shown, in this embodiment, a control component 17 is provided at the piston 13. The control component 17 includes an L-shaped connecting rod 18 fixed to the end of the piston 13. The surface of the L-shaped connecting rod 18 is movably connected to the inner wall of the thermal expansion tube 12 and the inner wall of the heat conduction tube 14. A circular hole 20 is provided at the horizontal part 9, and a circular hole 21 is provided on the burner head 2. The circular hole 20 and the circular hole 21 are connected. A sealing plate 19 is fixed to the bottom of the short side of the L-shaped connecting rod 18. The sealing plate 19 is attached to the horizontal part 9 and is used to... When hole 20 is blocked, as piston 13 moves due to the push of thermal expansion tube 12, it drives L-shaped connecting rod 18 to move synchronously. The movement of L-shaped connecting rod 18 causes sealing plate 19 to move away from hole 20. Due to the high gas flow rate inside burner head 2, a local negative pressure is formed, and hot gas in groove 8 will flow out through hole 20 and hole 21, returning to burner head 2 to mix with newly entered gas. This process realizes heat recovery and utilization, further improves the energy utilization rate of burner, reduces heat waste, and enhances the energy-saving performance of burner.

[0040] like Figure 4As shown in this embodiment, a protrusion 16 is provided at the end of the sealing ring 5 near the retaining ring 4. The protrusion 16 increases the contact area and the tightness of the connection between the sealing ring 5 and the retaining ring 4. When the sealing ring 5 is installed, the protrusion 16 can better cooperate with the retaining ring 4 to prevent the sealing ring 5 from axially displacing on the burner head 2. At the same time, when the sealing ring 5 deforms due to thermal expansion, the protrusion 16 helps to stabilize the position of the sealing ring 5, so that the sealing ring 5 maintains the correct orientation during the expansion process, thereby more effectively filling the gap between the burner head 2 and the boiler and improving the sealing effect.

[0041] like Figure 4 As shown, in this embodiment, the sealing plate 19 is a rubber plate with an arc-shaped chamfer at its edge. The rubber plate has good elasticity and sealing properties, and can fit tightly against the horizontal part 9, effectively blocking the round hole 20 and preventing the hot air in the groove 8 from leaking out prematurely. The arc-shaped chamfer design reduces the friction between the sealing plate 19 and the horizontal part 9 when the sealing plate 19 moves under the drive of the L-shaped connecting rod 18, making the movement smoother. At the same time, the arc-shaped chamfer can prevent the sealing plate 19 from scratching and damaging the horizontal part 9 during the movement, ensuring the integrity of the structure and extending the service life of the equipment.

[0042] like Figure 3 As shown, in this embodiment, a barrier ring 6 is fixed to the end of the sealing ring 5. The barrier ring 6 is sleeved on the outer circumferential surface of the burner head 2. The barrier ring 6 can initially block the hot gas leaking to the sealing ring 5, slowing down the rate at which the hot gas diffuses into the surrounding environment. During the process of inserting the burner head 2 into the boiler, the barrier ring 6 can also protect the sealing ring 5 from scratches and collisions at the boiler interface, extending the service life of the sealing ring 5. In addition, the barrier ring 6 provides an additional support structure for the sealing ring 5, enhancing the stability of the sealing ring 5 on the burner head 2 and helping to improve the overall sealing performance.

[0043] like Figure 3 As shown, in this embodiment, the end of the barrier ring 6 is provided with a guide surface 7. The guide surface 7 facilitates the accurate insertion of the burner head 2 into the boiler interface. During the insertion process, the guide surface 7 can guide the burner head 2 to smoothly enter the boiler, reducing the risk of damage to the sealing ring 5 due to insertion deviation. At the same time, the guide surface 7 can make the connection between the burner head 2 and the boiler interface tighter, creating better conditions for the subsequent filling of gaps by the sealing ring 5, improving the sealing performance of the connection between the burner head 2 and the boiler, and further reducing the possibility of heat leakage.

[0044] Working principle: Vegetable oil fuel is stored in a special storage tank and connected to the burner body 1 through a delivery pipeline. Since vegetable oil is liquid at normal temperature and pressure, it has stable fluidity and can be safely and efficiently delivered to the combustion part.

[0045] When the burner power is turned on, the ignition device starts working, providing an initial ignition source for combustion. At the same time, the preheating system inside the burner starts, preheating the burner head 2 and the surrounding area, so that the vegetable oil fuel can reach a good combustion state more quickly and improve the start-up efficiency.

[0046] Before the burner head 2 is inserted into the boiler, the sealing mechanism 3 is installed in place, the retaining ring 4 is firmly installed on the outer circumference of the burner head 2, and the sealing ring 5 is fitted onto the burner head 2 and is in a movable state. During the insertion into the boiler, the guide surface 7 of the barrier ring 6 assists the burner head 2 to be inserted accurately. Then, the sealing ring 5 initially fills the gap between the burner head 2 and the boiler with its own elasticity, initially blocking the heat loss.

[0047] Vegetable oil fuel is mixed with air in proportion at the burner head 2 and then starts to burn, releasing a large amount of heat to heat the boiler. During the combustion process, if the hot air generated by the combustion flows into the groove 8 on the outer circumference of the sealing ring 5, the heat conduction pipe 14 in the groove 8 absorbs the heat of the hot air.

[0048] The heat pipe 14 transfers heat to the thermal expansion pipe 12. The thermal expansion pipe 12 expands due to heat and pushes the piston 13, causing the hydraulic oil in the round pipe 10 to flow into the expansion chamber 15. As a result, the sealing ring 5 expands, further enhancing the sealing effect with the boiler.

[0049] At the same time, the movement of piston 13 drives L-shaped connecting rod 18, causing sealing plate 19 to move away from round hole 20. High-pressure hot gas in groove 8 flows back to combustion head 2 through round hole 20 and round hole 21, mixing with newly entered fuel and air to achieve heat recovery and utilization, improve combustion efficiency, and reduce energy consumption.

[0050] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
