[0002] In the field of combustion device technology, the performance of gas-liquid burners directly depends on the mixing ratio of fuel and gas. Traditional burners typically use a single mechanical valve or electronic control system to regulate the flow of gas and liquid. However, these methods suffer from problems such as insufficient adjustment accuracy, slow response speed, and complex maintenance. Especially under different operating conditions, traditional burners have difficulty achieving rapid and accurate ratio adjustment, resulting in low combustion efficiency and even potential safety hazards.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Example: Reference Figure 1-Figure 7 A burner with high-precision regulation of gas-liquid entry ratio includes an air supply pipe 101, on which a velocity regulating tube 102, an atomizing nozzle 103, and a combustion cone 104 are provided. The two ends of the velocity regulating tube 102 are fixedly connected to the air supply pipe 101 and the combustion cone 104 respectively, and the atomizing nozzle 103 is fixedly connected to the combustion cone 104.

The inner diameters of the air supply pipe 101 and the combustion cone 104 are equal, and the inner diameter of the air supply pipe 101 is larger than the inner diameter of the velocity regulating tube 102. A Venturi tube is formed between the air supply pipe 101, the velocity regulating tube 102, and the combustion cone 104.

[0024] An air intake assembly is provided on the air supply pipe 101, and the air intake assembly includes an air supply shell 105. A plurality of diversion air pipes 110 are fixedly provided in a circular array between the air supply shell 105 and the air supply pipe 101. A centrifugal impeller 111 is rotatably installed on the inner side of the air supply shell 105. An air intake motor 109 is fixedly installed on the air supply shell 105. The output shaft of the air intake motor 109 is fixedly connected to the centrifugal impeller 111. An air intake pipe 106 is fixedly provided on the air supply shell 105. The axes of the air supply shell 105, the air intake pipe 106, the centrifugal impeller 111 and the air supply pipe 101 are in the same straight line. One end of the diversion air pipe 110 is connected to the air supply shell 105, and the other end of the diversion air pipe 110 is connected to the air supply pipe 101.

[0025] A liquid inlet assembly is provided on the speed regulating tube 102, and the liquid inlet assembly includes an annular liquid feeding chamber 107. A plurality of diversion liquid pipes 112 are fixedly provided in a circular array between the annular liquid feeding chamber 107 and the speed regulating tube 102. A liquid inlet pipe 108 is symmetrically fixedly provided on the annular liquid feeding chamber 107. The axes of the annular liquid feeding chamber 107 and the speed regulating tube 102 are on the same straight line. One end of the diversion liquid pipe 112 is connected to the annular liquid feeding chamber 107, and the other end of the diversion liquid pipe 112 is connected to the speed regulating tube 102.

[0026] Start the air intake motor 109 to drive the centrifugal impeller 111 to rotate, and the gas enters the air supply housing 105 along the air intake pipe 106. Under the action of the centrifugal impeller 111, the gas enters the air supply pipe 101 along the bypass pipe 110. The gas entering the air supply pipe 101 passes through the speed regulating pipe 102 and is ejected from the combustion cone 104. The gas flowing through the speed regulating pipe 102 causes the fuel in the annular liquid feeding tank 107 to enter the speed regulating pipe 102 along the bypass liquid pipe 112. When the gas and fuel move to the position of the combustion cone 104, they are atomized and mixed, and then burned in the atomizing nozzle 103. An igniter is provided on the atomizing nozzle 103, and the fuel in the annular liquid feeding tank 107 enters the annular liquid feeding tank 107 through the liquid inlet pipe 108.

[0027] A mechanical valve 114 is fixedly installed on the diversion air pipe 110, and a linkage unit 1 is provided between the mechanical valve 114 and the air supply pipe 101. The linkage unit 1 includes a limiting circular plate 122. An auxiliary circular plate 113 is fixedly installed on the end of the air supply pipe 101 farthest from the atomizing nozzle 103. The limiting circular plate 122 is rotatably installed on the auxiliary circular plate 113. A bevel gear 2 116 is fixedly installed on the limiting circular plate 122. A bevel gear 115 is fixedly installed on the valve stem of the mechanical valve 114. The bevel gear 115 and the corresponding bevel gear 2 116 are engaged to form a gear pair. Under the action of the bevel gear 115 and the bevel gear 2 116, when the limiting circular plate 122 rotates 180 degrees, the valve stem of the mechanical valve 114 rotates 90 degrees.

[0028] A mechanical valve 2 127 is fixedly installed on the shunt liquid pipe 112, and a linkage unit 2 is provided between the shunt liquid pipe 112 and the speed regulating pipe 102. The linkage unit 2 includes a limiting circular plate 2 130, which is fixedly installed on the valve stem of the mechanical valve 2 127.

[0029] The air supply pipe 101 and the speed regulating pipe 102 are both provided with a positioning assembly, and the positioning assembly includes a sector rack 119 and a sector limiting strip plate 121. The sector rack 119 and the sector limiting strip plate 121 are respectively used to adjust and limit the positions of the limiting circular plate 1 122 and the limiting circular plate 2 130. The limiting circular plate 1 122 is fixedly mounted with a linkage gear 1 117. When the linkage gear 1 117 and the corresponding sector rack 119 are engaged, a gear rack pair is formed. The limiting circular plate 2 130 is fixedly mounted with a linkage gear 2 129. When the linkage gear 2 129 and the corresponding sector rack 119 are engaged, a gear rack pair is formed.

[0030] A positioning ring plate 118 is rotatably mounted on both the auxiliary circular plate 113 and the auxiliary circular plate 2 128, and the sector rack 119 and the sector limiting strip plate 121 are fixedly mounted on the corresponding positioning ring plate 118. The circumferential directions of the positioning ring plate 118, the sector rack 119 and the sector limiting strip plate 121 are the same, and a positioning gear ring 120 is fixedly mounted on the positioning ring plate 118. An L-shaped support seat 126 is fixedly mounted on both the auxiliary circular plate 113 and the auxiliary circular plate 2 128, and a positioning motor 124 is fixedly mounted on the L-shaped support seat 126. A positioning gear 125 is fixedly mounted on the output shaft of the positioning motor 124, and the positioning gear 125 is meshed with the corresponding positioning gear ring 120 to form a gear pair.

[0031] Start the positioning motor 124 to drive the positioning gear 125 to rotate, so that the positioning gear ring 120 rotates, and the positioning ring plate 118, the sector rack 119, and the sector limit strip plate 121 corresponding to the positioning gear ring 120 rotate synchronously. When the sector rack 119 on the auxiliary circular plate 113 rotates to contact a certain linkage gear 117, at this time, the other linkage gears 117 are not engaged with the sector rack 119, and the sector rack 119 continues to rotate. The linkage gear 117 rotates, and the corresponding limit circular plate 122 rotates. Under the action of bevel gear 1 115 and bevel gear 2 116, the valve stem of mechanical valve 114 rotates, thereby controlling the opening and closing of mechanical valve 114.

[0032] When the sector rack 119 on the auxiliary circular plate 2 128 rotates to contact a certain linkage gear 2 129, at this time, the other linkage gears 2 129 are not engaged with the sector rack 119, and the sector rack 119 continues to rotate, and the linkage gear 2 129 rotates, which causes the corresponding limit circular plate 2 130 to rotate, and then causes the valve stem of the mechanical valve 2 127 to rotate, thereby controlling the opening and closing of the mechanical valve 2 127.

[0033] The limiting circular plate 122 is symmetrically provided with an arc-shaped slide groove 123 that cooperates with the fan-shaped limiting strip 121. The fan-shaped limiting strip 121 and the arc-shaped slide groove 123 are used to limit the rotation of the limiting circular plate 122. The limiting circular plate 2 130 is provided with two arc-shaped slide grooves 131 that cooperate with the fan-shaped limiting strip 121. The two arc-shaped slide grooves 131 are oriented vertically. The arc-shaped slide grooves 131 and the corresponding fan-shaped limiting strip 121 are used to limit the rotation of the limiting circular plate 2 130.

[0034] In the initial position, the mechanical valve 114 on the auxiliary circular plate 113 is in a closed state. At this time, the arc-shaped sliding groove 123 on the limiting circular plate 122 corresponding to the mechanical valve 114 is engaged with the fan-shaped limiting strip plate 121. At this time, the fan-shaped rack 119 is not in contact with the linkage gear 117. Under the action of the fan-shaped limiting strip plate 121, the limiting circular plate 122 cannot rotate freely, that is, the valve stem of the mechanical valve 114 is locked, thereby locking the closed state of the mechanical valve 114.

[0035] Start the adjustment motor 124 on the auxiliary circular plate 113 to drive the corresponding adjustment gear ring 120 to rotate, so that the sector rack 119 and the sector limiting strip plate 121 rotate synchronously, and the sector limiting strip plate 121 rotates relative to the arc chute 123, so that the sector limiting strip plate 121 is disengaged from the limiting circular plate 122 in the rotation direction. At this time, the sector rack 119 is engaged with the linkage gear 117 corresponding to the limiting circular plate 122, and the other limiting circular plates 122 are all in engagement with the sector limiting strip plate 121 and cannot rotate. The sector rack 119 continues to rotate, and the linkage gear 117 rotates, thereby realizing the control of the mechanical valve 114 corresponding to the limiting circular plate 122. When the sector rack 119 makes the linkage gear When 117 rotates 180 degrees, the valve stem of the mechanical valve 114 rotates 90 degrees, that is, the mechanical valve 114 is in a fully open state, and the other arc-shaped slide groove 123 on the limiting circular plate 122 corresponding to the mechanical valve 114 moves to the position closest to the axis of the air supply pipe 101. The arc-shaped slide groove 123 and the circumferential direction of the air supply pipe 101 are the same. At this time, the sector rack 119 disengages from the linkage gear 117, and the sector limiting strip plate 121 re-engages with the other arc-shaped slide groove 123 on the limiting circular plate 122. Repeat the above steps to realize the opening of each mechanical valve 114 in turn, thereby realizing the control of the amount of gas entering the air supply pipe 101. Perform the above steps in reverse to close each mechanical valve 114 in turn.

[0036] The adjusting motor 124 on the auxiliary circular plate 128 is started to drive the corresponding adjusting gear ring 120 to rotate, so that the sector rack 119 and the sector limiting strip plate 121 rotate synchronously, and the sector limiting strip plate 121 rotates relative to the arc chute 131, so that the sector limiting strip plate 121 is disengaged from the limiting circular plate 130 in the rotation direction. At this time, the linkage gear 1 117 is engaged with the linkage gear 2 129 corresponding to the limiting circular plate 130, and the other limiting circular plates 130 are all in engagement with the sector limiting strip plate 121 and cannot rotate. The sector rack 119 continues to rotate, and the linkage gear 2 129 rotates, thereby realizing the control of the mechanical valve 2 127 corresponding to the limiting circular plate 130. When the sector rack 119 makes the sector limiting strip plate 130 When the linkage gear 2 129 rotates 90 degrees, the valve stem of the mechanical valve 2 127 rotates 90 degrees, that is, the mechanical valve 2 127 is in a fully open state, and the other arc-shaped slide groove 2 131 on the limiting circular plate 2 130 corresponding to the mechanical valve 2 127 moves to the position closest to the axis 100. The circumferential direction of the arc-shaped slide groove 2 131 is the same as that of 100. At this time, the sector rack 119 disengages from the linkage gear 2 129, and the sector limiting strip plate 121 re-engages with the other arc-shaped slide groove 2 131 on the limiting circular plate 2 130. Repeat the above steps to realize the opening of each mechanical valve 2 127 in turn, thereby realizing the control of the amount of fuel entering the speed regulating tube 102. Perform the above steps in reverse to close each mechanical valve 2 127 in turn.

[0037] Flow sensors are fixedly installed inside the air supply pipe 101 and the speed regulating pipe 102 , and the flow rates of the air supply pipe 101 and the speed regulating pipe 102 are monitored by the flow sensors.

[0038] Working principle: According to the fuel and gas ratio requirements, the two position adjustment motors 124 are started to open the required mechanical valve 114 and mechanical valve 2 127. By controlling the valve stem rotation angle of the last mechanical valve 114 and mechanical valve 2 127 that need to be opened, the flow rate of mechanical valve 114 and mechanical valve 2 127 can be precisely controlled. After completing the adjustment of mechanical valve 114 and mechanical valve 2 127, the air intake motor 109 is started to drive the centrifugal impeller 111 to rotate. The gas enters the air supply pipe 101 along the air supply shell 105 through the bypass air pipe 110. After the air flow enters the speed regulating pipe 102, the fuel enters the speed regulating pipe 102 along the bypass liquid pipe 112. Finally, atomization and mixing occur when entering the combustion cone 104, and the atomized and mixed fuel is burned in the atomizing nozzle 103.

[0039] The present invention is not limited to the above-mentioned specific embodiments. Various modifications made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
