Description

Technical Field

[0001] This utility model relates to the field of fuel nozzle technology, and in particular to a fuel fine atomization device. Background Technology

[0002] A fuel atomization device is a specialized piece of equipment that uses a specific structure to deliver fuel and atomizing gas in a specific ratio to a nozzle, and then uses the nozzle's atomization function to break the fuel into fine droplets. Its core function is to improve the atomization quality of the fuel, increasing the contact area between the fuel and air, thereby promoting complete combustion. This not only effectively improves fuel utilization and reduces energy consumption, but also reduces the emission of incomplete combustion products. It is widely used in industrial boilers, internal combustion engines, burners, and other equipment requiring efficient fuel combustion. However, existing fuel atomization devices still have many shortcomings, making it difficult to meet the diverse needs of practical applications. These shortcomings are mainly reflected in the following two aspects: First, the nozzle angle adjustment is limited. Most existing devices have fixed nozzle installation structures. Once assembled, the spray angle cannot be flexibly adjusted according to combustion conditions, furnace structure, or heating requirements. This results in the atomized fuel droplets failing to accurately cover the target combustion area, easily leading to incomplete combustion and uneven temperature distribution, affecting combustion efficiency and equipment operational stability. Second, the spray gun length is not adjustable. The main body length of existing spray guns is usually fixed and cannot be adapted to parameters such as furnace depth and burner installation position in actual application scenarios. When applied to different specifications of combustion equipment, either the spray gun is too short, resulting in insufficient fuel injection distance, or the spray gun is too long, causing installation interference or the fuel atomization area deviating from the ideal position, reducing the device's versatility and adaptability. Therefore, it is necessary to provide a new fuel atomization device to solve the above-mentioned technical problems. Utility Model Content

A limiting block is connected to the first support plate. A limiting groove is opened inside the limiting block, and a limiting ball is slidably connected inside the limiting groove. One end of the limiting ball is fixedly connected to a first connecting rod. By horizontally pushing and pulling the first connecting rod, the limiting ball slides in the limiting groove, thereby driving the limiting block, the rotating block, and the nozzle to rotate. A driven gear is symmetrically rotatably connected inside the first support plate. The inner wall of the driven gear is threadedly connected to the outer wall of the oil hose and the air hose. The first support plate is slidably connected to the oil hose and the air hose via a spline. By rotating the driven gear, the oil hose and the air hose slide relative to the first support plate.

[0006] Preferably, one end of the second connecting rod is rotatably connected to three sets of insert rods, and one end of the first connecting rod has a slot on its outer wall. The slot is an arc-shaped groove, and the bottom end of the insert rod has an arc-shaped rounded corner design. The bottom end of the insert rod is inserted into the slot.

[0007] Preferably, a fixing ring is fixedly connected to the outer wall of the second connecting rod near the first connecting rod, and a retaining ring is slidably connected to the outer wall of the second connecting rod. One end of the retaining ring is sleeved on the outside of the fixing ring, and the retaining ring is used to compress the insert rod.

[0009] Preferably, a motor is fixedly connected inside the first tray, and the output end of the motor is fixedly connected to the drive gear.

[0010] Compared with related technologies, the fuel fine atomization device provided by this utility model has the following beneficial effects: Achieve flexible adjustment of nozzle angle to improve combustion adaptability This invention utilizes a linkage structure consisting of an electric push rod, a second connecting rod, a first connecting rod, a limiting ball, a limiting block, and a rotating block. By simply activating the electric push rod, the limiting ball slides within the limiting groove of the limiting block, thereby causing the rotating block and the nozzle to rotate around the axis between the mounting blocks, achieving precise adjustment of the nozzle angle. This design effectively solves the problems of fixed nozzle settings and inability to adapt to different combustion conditions and furnace structures in existing devices. It allows atomized fuel droplets to accurately cover the target combustion area, reducing incomplete combustion and significantly improving combustion efficiency and equipment operational stability. Supports spray gun length adjustment to enhance equipment versatility. The device utilizes a motor, driving gear, driven gear, and spline sliding connection structure. After the motor is started, the driven gear is driven to rotate via gear transmission. With the spline restricting the rotation of the oil and air hoses, the rotational motion of the driven gear is converted into linear sliding of the oil and air hoses along the spline direction, thereby moving the nozzle back and forth to adjust the effective length of the spray gun. Simultaneously, the synchronously activated electric push rod drives the second connecting rod to slide synchronously, ensuring the nozzle angle remains stable during length adjustment. This design overcomes the limitation of fixed spray gun length in existing devices, allowing for flexible adjustment of the spray gun length based on parameters such as furnace depth and burner installation position. It effectively avoids installation interference and mismatched spray distances, significantly improving the device's versatility and adaptability to different scenarios. This facilitates quick connection and disconnection of components, improving maintenance efficiency. The first and second connecting rods employ a combination structure of a plug, slot, retaining ring, and spring. The rounded corner design at the bottom of the plug reduces frictional resistance during insertion. The 45° angled engagement between the retaining ring and the top of the plug allows for quick clamping and release. Disassembly is achieved by simply pulling the retaining ring towards the fixing ring to release the plug. Connection is achieved by pushing the retaining ring, utilizing the inclined plane force to press the plug into the slot for fixation. This design enables rapid connection and disconnection of the first and second connecting rods, facilitating the inspection, replacement, and maintenance of components such as the nozzle and hose. It significantly reduces operational difficulty and improves the convenience and efficiency of equipment maintenance. Attached Figure Description

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0014] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0015] Please see Figures 1 to 5 A fuel atomization device includes: a first support plate 1; a second support plate 2 fixedly connected to one side of the first support plate 1; an oil hose 3 and an air hose 4 slidably connected to the second support plate 2, the oil hose 3 and the air hose 4 being symmetrically arranged; mounting blocks 5 symmetrically arranged on the side of the second support plate 2 away from the first support plate 1, the two mounting blocks 5 being fixedly connected to the oil hose 3 and the air hose 4 respectively; a rotating block 6 rotatably connected between the two mounting blocks 5; a nozzle 7 fixedly connected to the end of the rotating block 6 away from the oil hose 3, the nozzle 7 being connected to the oil hose 3 and the air hose 4 via a pipe; and the top of the rotating block 6... A limiting block 8 is fixedly connected, with a limiting groove inside the limiting block 8. A limiting ball 9 is slidably connected within the limiting groove, and a first connecting rod 10 is fixedly connected to one end of the limiting ball 9. By horizontally pushing and pulling the first connecting rod 10, the limiting ball 9 slides within the limiting groove, thereby driving the limiting block 8, the rotating block 6, and the nozzle 7 to rotate. A driven gear 11 is symmetrically rotatably connected inside the first support plate 1. The inner wall of the driven gear is threadedly connected to the outer wall of the oil hose 3 and the air hose 4. The first support plate 1 is slidably connected to the oil hose 3 and the air hose 4 via splines. Rotating the driven gear causes the oil hose 3 and the air hose 4 to slide relative to the first support plate 1. A driving gear 18 is rotatably connected inside the first support plate 1, and the driving gear 18 meshes with the two driven gears. A motor 19 is fixedly connected inside the first support plate 1, and the output end of the motor 19 is fixedly connected to the driving gear 18.

[0016] It should be noted that: the nozzle 7 is the nozzle 7 commonly used in existing atomizing oil guns, which is existing technology; the first support plate 1 is slidably connected to the oil hose 3 and the air hose 4 by a spline, and the spline restricts the rotational movement of the oil hose 3 and the air hose 4. When the driven gear rotates, the driven gear drives the oil hose 3 and the air hose 4 to slide along the spline direction through the thread.

[0017] Please see Figure 1 , Figure 4 and Figure 5 An electric push rod 12 is fixedly connected to the top of both the first tray 1 and the second tray 2. A second connecting rod 13 is fixedly connected to the output end of the electric push rod 12. A connecting groove is provided at the end of the second connecting rod 13 away from the electric push rod 12, and the first connecting rod 10 is inserted into the connecting groove. Three sets of insert rods 14 are rotatably connected inside one end of the second connecting rod 13. A slot is provided on the outer wall of one end of the first connecting rod 10. The slot is an arc-shaped slot, and the bottom end of the insert rod 14 is designed with an arc-shaped rounded corner. The bottom end of the insert rod 14 is inserted into the slot. A fixing ring 15 is fixedly connected to the outer wall of the second connecting rod 13 near the first connecting rod 10. A retaining ring 16 is slidably connected to the outer wall of the second connecting rod 13. One end of the retaining ring 16 is sleeved on the outside of the fixing ring 15 and is used to press the insertion rod 14. A spring 17 is sleeved on the outer wall of one end of the second connecting rod 13. One end of the spring 17 is fixedly connected to the fixing ring 15, and the other end of the spring 17 is fixedly connected to the inner wall of the retaining ring 16. The top of the insertion rod 14 is provided with a 45° bevel angle, and the end of the retaining ring 16 away from the fixing ring 15 is also provided with a 45° bevel angle.

[0018] It should be noted that when the oil hose 3 and air hose 4 slide, the electric push rod 12 needs to be started simultaneously. The electric push rod 12 drives the second connecting rod 13 to slide simultaneously, so as to avoid the change of nozzle 7 angle due to the sliding of the oil hose 3 and air hose 4. When it is necessary to adjust the nozzle 7 angle, only the electric push rod 12 needs to be started. The electric push rod 12 pushes or pulls the second connecting rod 13 horizontally, thereby driving the first connecting rod 10 to move horizontally. Through the limit ball 9, the limit block 8 is pushed to drive the rotating block 6 to rotate, and the limit ball 9 slides in the limit groove. The design of the insertion rod 14 and the slot allows the first connecting rod 10 and the second connecting rod 13 to be quickly connected and disconnected.

[0019] The working principle of the fuel fine atomization device provided by this utility model is as follows: Fuel delivery basic status: When the device is in its initial working state, the oil hose 3 is used to transport fuel, and the gas hose 4 is used to transport the gas required for atomization. Both are connected to the nozzle 7 (the nozzle 7 is commonly used in existing atomizing oil guns) through pipes, providing the material basis for the nozzle 7 to achieve fine fuel atomization. The first support plate 1 is connected to the oil hose 3 and the gas hose 4 by a spline sliding connection. The spline structure restricts the rotational movement of the oil hose 3 and the gas hose 4, allowing them to slide linearly along the spline direction only. The end of the oil hose 3 and the gas hose 4 away from the nozzle 7 is threaded to the inner wall of the driven gear in the first support plate 1. Both driven gears mesh with the driving gear 18, which is fixedly connected to the output end of the motor 19 fixed inside the first support plate 1. Meanwhile, the ends of the oil hose 3 and the air hose 4 near the nozzle 7 are respectively fixedly connected to two symmetrically arranged mounting blocks 5. A rotating block 6 is rotatably connected between the two mounting blocks 5. The end of the rotating block 6 away from the oil hose 3 is fixedly connected to the nozzle 7. A limiting block 8 fixedly connected to the top of the rotating block 6 has a limiting groove inside. One end of the limiting ball 9 slidably connected in the limiting groove is fixedly connected to the first connecting rod 10. The first connecting rod 10 and the second connecting rod 13 are inserted into the slot through the insert rod 14. The end of the second connecting rod 13 away from the first connecting rod 10 is fixedly connected to the output end of the electric push rod 12 fixed on the top of the first support plate 1 and the second support plate 2.

[0020] The process of adjusting the nozzle angle (7): When the nozzle 7 angle needs to be adjusted individually, only the electric push rod 12 is activated. The output end of the electric push rod 12 horizontally pushes or pulls the second connecting rod 13. The second connecting rod 13, through the cooperation of the insert rod 14 and the slot, drives the first connecting rod 10 to move horizontally synchronously. The first connecting rod 10 drives the limiting ball 9 to slide within the limiting groove of the limiting block 8. The sliding of the limiting ball 9 generates a pushing or pulling force on the limiting block 8. Since the rotating block 6 is rotatably connected to the mounting block 5, the force on the limiting block 8 drives the rotating block 6 to rotate around the rotation axis between the mounting blocks 5. The rotating block 6 then drives the nozzle 7, which is fixedly connected to it, to achieve angle adjustment to meet different atomization spray requirements.

[0021] Nozzle 7 position adjustment process: When the front and rear positions of the nozzle 7 need to be adjusted, the motor 19 is started. The output end of the motor 19 drives the drive gear 18 to rotate, and the drive gear 18 drives the two driven gears meshing with it to rotate synchronously. Since the driven gears are threadedly connected to the oil hose 3 and the air hose 4, and the spline structure restricts the rotation of the oil hose 3 and the air hose 4, the rotation of the driven gears is converted into linear sliding of the oil hose 3 and the air hose 4 along the spline direction through threaded transmission. The sliding of the oil hose 3 and the air hose 4 causes the mounting block 5, which is fixedly connected to it, to slide synchronously, and then drives the nozzle 7 to move in position through the rotating block 6. During this process, in order to prevent the angle of the nozzle 7 from changing due to the sliding of the oil hose 3 and the air hose 4, the electric push rod 12 needs to be started synchronously. The output end of the electric push rod 12 drives the second connecting rod 13 to slide in the same direction and speed as the oil hose 3 and the air hose 4. Through the linkage of the first connecting rod 10, the limiting ball 9, the limiting block 8 and the rotating block 6, it is ensured that the angle of the nozzle 7 remains unchanged when the position is moved.

[0022] The process of connecting and disconnecting the first connecting rod 10 and the second connecting rod 13: When it is necessary to disassemble the first connecting rod 10 and the second connecting rod 13, pull the retaining ring 16 towards the fixing ring 15. The retaining ring 16 slides on the outer wall of the second connecting rod 13 and compresses the spring 17. At this time, the squeezing effect of the retaining ring 16 on the insertion rod 14 is released. Since the slot is an arc-shaped groove and the bottom end of the insertion rod 14 is arc-shaped, the first connecting rod 10 can be easily pulled out from the connecting groove of the second connecting rod 13, thus achieving the disassembly of the two. When connection is required, the first connecting rod 10 is inserted into the connecting groove of the second connecting rod 13. The end of the first connecting rod 10 presses the insertion rod 14 at a 45° angle, causing the insertion rod 14 to rotate inward into the second connecting rod 13. When the slot on the first connecting rod 10 corresponds to the position of the insertion rod 14, under the elastic force of the spring 17, the retaining ring 16 slides towards the fixing ring 15. The 45° angle at the end of the retaining ring 16 away from the fixing ring 15 presses the insertion rod 14, causing the insertion rod 14 to be inserted into the slot, thus completing the quick connection between the first connecting rod 10 and the second connecting rod 13.

[0023] The process of connecting and disconnecting the first connecting rod 10 and the second connecting rod 13: Disassembly process: When it is necessary to disassemble the two, pull the retaining ring 16 towards the fixing ring 15. The retaining ring 16 slides on the outer wall of the second connecting rod 13 and compresses the spring 17. As the retaining ring 16 moves, the 45° angled fit between its inner wall and the top of the insertion rod 14 is released, and the insertion rod 14 loses its squeezing force. Since the bottom end of the insertion rod 14 has a rounded corner design, the frictional resistance with the inner wall of the slot is reduced, and the first connecting rod 10 can be easily pulled out from the connecting groove of the second connecting rod 13. The insertion rod 14 disengages from the slot along with the first connecting rod 10, thus achieving the disassembly of the two. Connection Process: When connecting the two, insert the first connecting rod 10 into the connecting groove of the second connecting rod 13. At this time, push the retaining ring 16 away from the fixing ring 15. The 45° angle of the end of the retaining ring 16 away from the fixing ring 15 cooperates with the 45° angle of the top of the insertion rod 14. Through the inclined plane, the force of the retaining ring 16 is converted into a force that causes the insertion rod 14 to rotate inward towards the second connecting rod 13. As the retaining ring 16 continues to move, the insertion rod 14 is gradually pressed into the slot of the first connecting rod 10, and the rounded corner at the bottom of the insertion rod 14 fits against the inner wall of the slot, ensuring a stable connection. When the retaining ring 16 moves to fit against the fixing ring 15, the spring 17 is in a naturally extended state, limiting the retaining ring 16. At this point, the insertion rod 14 is fully inserted into the slot, completing the rapid connection between the first connecting rod 10 and the second connecting rod 13.
