Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a natural gas burner nozzle. Background Technology

[0002] Natural gas burners are efficient and clean energy conversion devices that produce a high-temperature flame by precisely mixing natural gas and air and then igniting it for heating and industrial applications. Their design prioritizes combustion efficiency and safety, and they are typically equipped with automatic ignition, flame monitoring, and automatic adjustment systems to ensure a stable and easily controllable combustion process. Natural gas burners not only reduce harmful emissions from the combustion of traditional fuels but are also widely used in residential, commercial, and industrial settings due to their ease of operation and low maintenance costs.

[0003] Most natural gas burner nozzles currently in use employ a fixed-diameter orifice design. While this structure operates stably under specific conditions, its limitations become apparent when faced with varying fuel flow demands. Because the orifice size cannot be adjusted, the fuel supply cannot be precisely matched to changes in operating conditions, leading to uneven fuel supply and consequently, decreased combustion efficiency. Utility Model Content

[0004] One objective of this invention is to provide a natural gas burner nozzle that addresses the problem mentioned in the background that most currently used natural gas burner nozzles employ a fixed-diameter orifice design. While this structure operates stably under specific conditions, its limitations become apparent when faced with varying fuel flow demands. Because the orifice size cannot be adjusted, the fuel supply cannot be precisely matched to changes in operating conditions, leading to uneven fuel supply and consequently, a decrease in combustion efficiency.

[0005] A natural gas burner nozzle according to an embodiment of the present invention includes:

[0006] An adjustable mechanism includes a nozzle connected to a pipeline. The nozzle has an outer folding plate rotatably mounted on its outer front end in a circular shape, and an inner folding plate rotatably mounted on its inner front end in a circular shape. An outer guide plate and an inner guide plate are rotatably mounted on the front ends of the outer and inner guide plates, respectively. A first positioning rod and a second positioning rod are fixedly mounted on the front ends of the outer and inner guide plates, respectively. A waist-shaped arc plate is sleeved on the outer side of the second positioning rod. The first positioning rod is movably mounted inside the waist-shaped arc plate. The outer guide plate is connected to the nozzle via a drive assembly to adjust the nozzle diameter.

[0007] The fixing mechanism, installed inside the nozzle in the adjustable mechanism, is used to enhance the stability of the internal piping of the nozzle.

[0008] Preferably, the inner folding plate is arranged crosswise between the two outer folding plates.

[0009] Preferably, the outer and inner folding plates, which are circular in shape, intersect to form a cylindrical structure.

[0010] Preferably, both the first positioning rod and the second positioning rod have a positioning nut threaded onto their tops.

[0011] Preferably, the drive assembly includes a rotary cylinder threaded to the tail of the nozzle and a fixed seat fixed to the outside of the outer guide plate. A rotating ring is rotatably provided at the front end of the rotary cylinder, a push-pull rod is fixedly provided at the front end of the rotating ring, a push-pull ring is fixedly provided at the front end of the push-pull rod, a first rotating seat is fixedly provided at one end of the push-pull ring corresponding to the fixed seat, a first connecting rod is rotatably provided at the front end of the first rotating seat, a second rotating seat is fixedly provided at the front end of the first connecting rod, and a second connecting rod is rotatably provided between the second rotating seat and the fixed seat.

[0012] Preferably, there are several circular push-pull rods, and a reinforcing rib is fixedly provided between the fixed base and the outer guide plate.

[0013] Preferably, the fixing mechanism includes a fixing box fixed to the upper and lower ends of the inner side of the nozzle, a first magnetic stone fixedly installed on the top of the fixing box, a movable seat movably arranged inside the fixing box by a spring, a support arm symmetrically rotated on one side of the top of the movable seat, a pressure column fixedly installed at the center of the top of the movable seat, a positioning plate fixedly installed on the top of the support arm, a support base fixedly installed on the top of the pressure column, and a second magnetic stone installed on the top of the support base.

[0014] Preferably, the support arm and the positioning plate both extend through the interior of the fixing box, so that the positioning plate can tighten and position the pipe when the support seat is pressed down. The first magnetic stone and the second magnetic stone are magnetically connected to achieve pipe clamping and positioning when they are in contact and pipe loosening when they are released.

[0015] The beneficial effects of this utility model are:

[0016] This invention effectively avoids the problem of reduced combustion efficiency caused by uneven fuel supply through an adjustable mechanism. When the nozzle diameter needs to be adjusted, the rotating cylinder is rotated. Since the rotating cylinder is threadedly connected to the nozzle, and the rotating ring is rotatably connected to the rotating cylinder, the rotating ring can push the push-pull rod to the front end under the threaded rotation of the rotating cylinder and the nozzle. At this time, the movement of the push-pull ring is transmitted to the fixed seat fixed on the outer guide plate through the connecting rod assembly composed of the first rotating seat, the first connecting rod, the second rotating seat, and the second connecting rod. Since the outer guide plate and the inner guide plate are connected to the waist-shaped arc plate through the positioning rod, and the outer folding plate and the inner folding plate are rotatably connected to the outer guide plate and the inner guide plate respectively and cross to form a cylindrical structure, the radial movement of the outer guide plate will synchronously drive the inner guide plate and all the outer folding plates and the inner folding plates to change angles. Finally, the nozzle diameter of the entire nozzle front end can be changed. Therefore, this mechanism can adjust the nozzle size according to different fuel flow requirements, ensure that the fuel supply matches the changes in operating conditions, and improve combustion efficiency.

[0017] This invention effectively avoids the problem of unstable pipe connections affecting the normal operation of the burner through its fixing mechanism. When installing the pipe, simply press the pipe down on the support base, causing the pressure column to move down and compress the spring. At this time, the second magnetic stone on the support base is tightly attached to the first magnetic stone on the top of the fixing box, achieving self-locking through magnetic attraction. The pipe is firmly held in a clamped state by the cooperation of the positioning plate and the support base. Conversely, by using the upper support base, the second magnetic stone can be disengaged from the first magnetic stone, losing its magnetic constraint, and the pipe can then be quickly removed. Therefore, this fixing mechanism can enhance the stability of the pipe inside the nozzle, ensuring that the pipe will not loosen or shift during combustion, thus guaranteeing the normal operation of the burner.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] refer to Figure 1-4 A natural gas burner nozzle, comprising:

[0026] Adjustable mechanism 1 includes a nozzle 101 connected to a pipe. An outer folding plate 103 is rotatably mounted on the outer side of the nozzle 101's front end in a circular shape. An inner folding plate 106 is rotatably mounted on the inner side of the nozzle 101's front end in a circular shape. An outer guide plate 104 and an inner guide plate 107 are rotatably mounted on the front ends of the outer guide plate 104 and the inner guide plate 107, respectively. A first positioning rod 105 and a second positioning rod 108 are fixedly mounted on the front ends of the outer guide plate 104 and the inner guide plate 107, respectively. A waist-shaped arc plate 109 is sleeved on the outer side of the second positioning rod 108. The first positioning rod 105 is positioned... The outer guide plate 104 is movably arranged inside the waist-shaped arc plate 109. It is connected to the nozzle 101 via a drive assembly to adjust the nozzle diameter. The drive assembly includes a rotary cylinder 111 threaded to the tail of the nozzle 101 and a fixed seat 119 fixed to the outside of the outer guide plate 104. A rotating ring 112 is rotatably mounted at the front end of the rotary cylinder 111. A push-pull rod 113 is fixedly mounted at the front end of the rotating ring 112. A push-pull ring 114 is fixedly mounted at the front end of the push-pull rod 113. A first rotating seat 115 is fixedly mounted at one end of the push-pull ring 114 corresponding to one end of the fixed seat 119. A first connecting rod 116 is rotatably mounted on the front end of the first rotating seat 115, and a second rotating seat 117 is fixedly mounted on the front end of the first connecting rod 116. A second connecting rod 118 is rotatably mounted between the second rotating seat 117 and the fixed seat 119. When the nozzle diameter needs to be adjusted, the rotating cylinder is rotated. Since the rotating cylinder is threadedly connected to the nozzle, and the rotating ring is rotatably connected to the rotating cylinder, the rotating ring can push the push-pull rod to move forward under the threaded rotation of the rotating cylinder and the nozzle. At this time, the movement of the push-pull ring is transmitted through the first rotating seat, the first connecting rod, the second rotating seat, and the... The connecting rod assembly formed by the second connecting rod transmits the power to the fixed seat fixed on the outer guide plate. Since the outer guide plate and the inner guide plate are connected to the waist-shaped arc plate through the positioning rod, and the outer folding plate and the inner folding plate are rotatably connected to the outer guide plate and the inner guide plate respectively and cross to form a cylindrical structure, the radial movement of the outer guide plate will synchronously drive the inner guide plate and all the outer folding plates and the inner folding plates to change angles. Ultimately, the nozzle diameter can be changed at the front end of the entire nozzle. Therefore, the mechanism can adjust the nozzle size according to different fuel flow requirements to ensure that the fuel supply matches the changes in working conditions.

[0027] The fixing mechanism 2 is installed inside the nozzle 101 in the adjustable mechanism 1 to enhance the stability of the internal pipes of the nozzle 101. The fixing mechanism 2 includes a fixing box 201 fixed to the upper and lower ends of the inner side of the nozzle 101. A first magnetic stone 202 is fixedly installed on the top of the fixing box 201. A movable seat 203 is movably arranged inside the fixing box 201 via a spring 204. A support arm 205 is symmetrically rotated on one side of the top of the movable seat 203. A pressure column 206 is fixedly installed at the center of the top of the movable seat 203. A positioning plate 207 is fixedly installed on the top of the support arm 205. A support base 208 is fixedly installed on the top of the pressure column 206. The top of the support base 208 is equipped with a second magnetic stone 209. When installing the pipe, simply press the support base down with the pipe to move the pressure column down and compress the spring. At this time, the second magnetic stone on the support base is tightly attached to the first magnetic stone on the top of the fixing box. The magnetic attraction achieves self-locking, keeping the pipe firmly clamped in the position with the cooperation of the positioning plate and the support base. Conversely, by using the upper support base, the second magnetic stone can be disengaged from the first magnetic stone and lose the magnetic attraction constraint. At this time, the pipe can be quickly removed. Therefore, this fixing mechanism can enhance the stability of the pipe inside the nozzle and ensure that the pipe will not loosen or shift during combustion.

[0028] Example 1: The inner folding plate 106 is intersected between the two outer folding plates 103. The circular outer folding plates 103 and inner folding plates 106 intersect to form a cylindrical structure, which not only enhances the overall stability of the nozzle, but also makes the nozzle adjustment more precise. The top of the first positioning rod 105 and the second positioning rod 108 are both threaded with positioning nuts 110, which ensures the reliability and stability of the nozzle when adjusting the nozzle diameter, and provides a strong guarantee for fuel supply under different working conditions.

[0029] Example 2: Several circular push-pull rods 113 are provided, making the drive assembly move the outer guide plate 104 more evenly and stably, improving the accuracy of nozzle diameter adjustment. A reinforcing rib 102 is fixedly provided between the fixed seat 119 and the outer guide plate 104, enhancing the strength and rigidity of the structure and preventing deformation during adjustment. The support arm 205 and the positioning plate 207 both penetrate the interior of the fixed box 201, and are used to clamp and position the pipe when the support seat 208 is pressed down. The first magnetic stone 202 and the second magnetic stone 209 are magnetically connected to achieve pipe clamping and positioning when they are in contact and pipe release when they are released, realizing rapid clamping and releasing of the pipe, convenient operation, and effectively ensuring the stability and reliability of the pipe connection.

[0030] Working principle: During pipe installation, the pipe presses down on the support base 208, causing the pressure column 206 to move down and compress the spring 204. At this time, the second magnetic stone 209 on the support base 208 is tightly attached to the first magnetic stone 202 on the top of the fixing box 201, achieving self-locking through magnetic attraction. The pipe is firmly held in a clamped state by the cooperation of the positioning plate 207 and the support base 208. When the pipe needs to be released, the support base 208 is released. Under the action of the spring 204, the moving base 203 returns to its original position, the positioning plate 207 releases the pipe, and the magnetic connection between the first magnetic stone 202 and the second magnetic stone 209 disappears, allowing the pipe to be quickly removed. When the nozzle diameter needs to be adjusted, the operator rotates the rotary cylinder 111. Since the rotary cylinder 111 is threadedly connected to the nozzle 101, and the rotating ring 112 is rotatably connected to the rotary cylinder 111, the rotating ring 112 can be adjusted between the rotary cylinder 111 and the nozzle. The screw rotation of 101 pushes the push-pull rod 113 to move towards the front end. The movement of the push-pull rod 113 is transmitted to the fixed seat 119 fixed on the outer guide plate 104 through the linkage assembly composed of the first rotating seat 115, the first connecting rod 116, the second rotating seat 117, and the second connecting rod 118. Since the outer guide plate 104 and the inner guide plate 107 are connected to the waist-shaped arc plate 109 through the first positioning rod 105 and the second positioning rod 108, and the outer folding plate 103 and the inner folding plate 106 are rotatably connected to the outer guide plate 104 and the inner guide plate 107 respectively and cross to form a cylindrical structure, the radial movement of the outer guide plate 104 will synchronously drive the inner guide plate 107 and all the outer folding plates 103 and the inner folding plates 106 to change angles. Finally, the nozzle front end can change the nozzle diameter. This mechanism can adjust the nozzle size according to different fuel flow requirements to ensure that the fuel supply matches the changes in working conditions.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
