Description

Technical Field

[0001] The utility model relates to the technical field of gas furnace air supply, in particular to an efficient air supply device for a gas boiler. Background Technique

[0002] In large gas boilers, it is often necessary to send a large amount of air into the boiler to ensure the normal progress of the oxidation reaction in the boiler. Among them, the publication number is: CN 111810426 B, which discloses an efficient air supply device for a gas boiler, including a machine shell, an acceleration component and a cleaning component. An acceleration chamber and a storage chamber are arranged in the machine shell. The acceleration chamber is communicated with the storage chamber. The acceleration component is rotatably arranged in the acceleration chamber. The cleaning component is movably arranged between the acceleration chamber and the storage chamber. And an air inlet, an air outlet one and an air outlet two communicated with the acceleration chamber are arranged on the machine shell. Valves are respectively arranged in the air outlet one and the air outlet two. When the device is in the shutdown and cleaning state, the air outlet one is closed and the air outlet two is opened. The cleaning component moves from the storage chamber to the acceleration chamber, and the cleaning component performs a cleaning operation on the acceleration component. When the device is in the sewage discharge state, the air outlet one is closed and the air outlet two is opened. The cleaning component moves to the storage chamber again. The acceleration component sends the residual dust in the acceleration chamber out through the air outlet two through the air flow, achieving the purpose of rapid ash cleaning.

[0003] The following deficiencies exist in the above scheme: (1) After the external air enters the machine shell through the air inlet, some dust will adhere to the inner cavity of the machine shell, but most of the dust will enter the gas furnace along with the air, affecting the combustion efficiency of the gas; (2) After the air accelerates and enters the inner cavity of the gas furnace, because it contains other components that cannot support combustion, it cannot immediately play the role of supporting combustion, but will instead affect gas combustion and the combustion efficiency. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides an efficient air supply device for a gas boiler, which has the advantages of being convenient for filtering and cleaning dust and mixing air and gas for combustion support, and avoids the problem that dust and air directly enter the gas furnace and affect the combustion efficiency.

[0005] To achieve the purpose of being convenient for filtering and cleaning dust and mixing air and gas for combustion support, the utility model provides the following technical scheme:

[0006] An efficient air supply device for a gas boiler, including a barrel body. Air inlet pipes and gas inlet pipes are respectively fixedly connected to the side walls on both sides of the barrel body. An air outlet pipe is fixedly connected to the side wall of the barrel body below the gas inlet pipe. A filtering component is fixedly connected to the end of the air inlet pipe. The filtering component is used for filtering dust in the air. A mixing component is installed on the inner wall of the barrel body. The mixing component is used for mixing the air entering from the air inlet pipe and the gas entering from the gas inlet pipe. It also includes:

[0007] The filtering component includes a filtering box, which is clamped at the end of the air inlet pipe. A filter plate is slidably connected to the inner wall of the filtering box, and a spring is fixedly connected between the filter plate and the filtering box. An installation plate is fixedly connected to the inner wall of the air inlet pipe, and a first servo motor is fixedly connected to the side wall of the installation plate. The output end of the first servo motor is fixedly connected to a first rotating shaft, and a fan blade is fixedly connected to the side wall of the first rotating shaft. A collision block is fixedly connected to the side wall of the filter plate on one side of the fan blade, and a rotating column is fixedly connected to the side wall of the first rotating shaft, and the rotating column can be attached to the collision block. The dust existing in the air will be filtered by the filter plate, thus preventing the dust from entering the gas furnace and affecting the gas combustion efficiency. And when the first rotating shaft drives the rotating column to rotate, the rotating column squeezes the filter plate through the collision block when rotating, thus causing the spring to be squeezed and forming a rebounding force, making the filter plate vibrate and shaking off the dust adsorbed on the surface of the filter plate, preventing the dust from blocking the filter plate and reducing the air intake volume, which affects the combustion.

[0008] According to some embodiments, the mixing component includes a second servo motor, which is fixedly installed on the top of the barrel. The output end of the second servo motor in the inner cavity of the barrel is fixedly connected to a second rotating shaft. A pressing plate is threadedly connected to the side wall of the second rotating shaft above the gas inlet pipe. A stirring plate is fixedly connected to the side wall of the second rotating shaft below the pressing plate, and a limiting column penetrates through the top of the barrel. Check valves are arranged in the inner cavities of the air inlet pipe, the gas inlet pipe and the outlet pipe. The second servo motor drives the second rotating shaft and the stirring plate to rotate to stir and mix the air and gas in the inner cavity of the barrel. And because the second rotating shaft and the pressing plate are threadedly connected, the pressing plate can slide on the side wall of the second rotating shaft. When the pressing plate slides downward, it squeezes the mixed gas in the inner cavity of the barrel to reach the furnace body through the outlet pipe to accelerate combustion support. When the pressing plate slides upward, it accelerates the intake of the air inlet pipe and the gas inlet pipe.

[0009] According to some embodiments, a first connecting plate is fixedly connected to the end of the air inlet pipe, and a second connecting plate is fixedly connected to the end of the filtering box. A threaded bolt is threadedly connected to the side wall of the first connecting plate, and the first connecting plate and the second connecting plate are fixedly connected by the threaded bolt. A collecting box is clamped at the bottom of the filtering box below the filter plate. The collision block is hemispherical. The air inlet pipe and the filtering box are fixedly connected by the first connecting plate and the second connecting plate using the threaded bolt. Rotating the threaded bolt can detach the filtering box from the side wall of the air inlet pipe, which is convenient for cleaning it.

[0010] Beneficial effects

[0011] The utility model provides a high-efficiency gas supply device for a gas boiler, which has the following beneficial effects:

[0012] (1) The high-efficiency gas supply device of the gas boiler drives the first rotating shaft and the fan blades to rotate by the first servo motor to form wind force, sucking air into the air inlet pipe. The dust existing inside it will be filtered by the filter plate, thus preventing dust from entering the gas furnace and affecting the gas combustion efficiency. And during the rotation of the first rotating shaft, it will also drive the rotating column to rotate. When the rotating column rotates, it squeezes the filter plate through the collision block, thus causing the spring to be squeezed and forming a rebound force, making the filter plate vibrate and shaking off the dust adsorbed on the surface of the filter plate, preventing the filter plate from being blocked by dust and reducing the air intake volume, which affects combustion.

[0013] (2) The high-efficiency gas supply device of the gas boiler drives the second rotating shaft and the stirring plate to rotate by the second servo motor to stir and mix the air and gas in the inner cavity of the barrel. And since the second rotating shaft and the pressing plate are threadedly connected, the pressing plate can slide on the side wall of the second rotating shaft. When the pressing plate slides downward, it squeezes the mixed gas in the inner cavity of the barrel to reach the furnace body through the air outlet pipe, accelerating combustion support. When the pressing plate slides upward, it accelerates the intake of the air inlet pipe and the gas inlet pipe. Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0020] Referring to Figures 1 - 4 , a high-efficiency gas delivery device for a gas boiler, includes a barrel body 1. Air inlet pipes 101 and gas inlet pipes 102 are respectively fixedly connected to the side walls on both sides of the barrel body 1. An air outlet pipe 103 is fixedly connected to the side wall of the barrel body 1 below the gas inlet pipe 102. A filtering component 2 is fixedly connected to the end of the air inlet pipe 101. The filtering component 2 is used for filtering dust in the air. A mixing component 3 is installed on the inner wall of the barrel body 1. The mixing component 3 is used for mixing the air entering from the air inlet pipe 101 and the gas entering from the gas inlet pipe 102. It further includes:

[0021] The filtering component 2 includes a filtering box 201. The filtering box 201 is clamped at the end of the air inlet pipe 101. A filtering plate 202 is slidably connected to the inner wall of the filtering box 201. A spring 203 is fixedly connected between the filtering plate 202 and the filtering box 201. A mounting plate 204 is fixedly connected to the inner wall of the air inlet pipe 101. A first servo motor 205 is fixedly connected to the side wall of the mounting plate 204. A first rotating shaft 206 is fixedly connected to the output end of the first servo motor 205. A fan blade 207 is fixedly connected to the side wall of the first rotating shaft 206;

[0022] A collision block 208 is fixedly connected to the side wall of the filtering plate 202 on one side of the fan blade 207. A rotating column 209 is fixedly connected to the side wall of the first rotating shaft 206, and the rotating column 209 can be attached to the collision block 208;

[0023] It should be noted that: When the first servo motor 205 on the side wall of the mounting plate 204 is turned on, the first servo motor 205 drives the first rotating shaft 206 to rotate, and the first rotating shaft 206 drives the fan blade 207 to rotate to form wind power, sucking air from the outside of the filter box 201 through the air inlet pipe 101, and then entering the inner cavity of the barrel 1. And when the air passes through the filter box 201, the dust existing inside it will be filtered by the filter plate 202, preventing the dust from entering the barrel 1 through the air inlet pipe 101 and then entering the furnace body, causing pollution. And during the rotation of the first rotating shaft 206, it will also drive the rotating column 209 to rotate. When the rotating column 209 rotates, it squeezes the filter plate 202 to slide through the collision block 208, thereby causing the spring 203 between the filter plate 202 and the filter box 201 to be squeezed, forming a rebound force. Through the rebound force of the spring 203, the filter plate 202 vibrates, shaking off the dust adsorbed on the surface of the filter plate 202, preventing the dust from blocking the filter plate 202 and reducing the air intake, affecting combustion. Among them, the air enters the barrel 1, and the gas enters the barrel 1 through the gas inlet pipe 102. The mixing component 3 is used to mix the two, facilitating sufficient subsequent combustion.

[0024] Refer to Figures 1 - 4 , the mixing component 3 includes a second servo motor 301. The second servo motor 301 is fixedly installed on the top of the barrel 1. At the output end of the second servo motor 301 located in the inner cavity of the barrel 1, a second rotating shaft 302 is fixedly connected;

[0025] On the side wall of the second rotating shaft 302 above the gas inlet pipe 102, a pressing plate 303 is threadedly connected. On the side wall of the second rotating shaft 302 below the pressing plate 303, a stirring plate 304 is fixedly connected;

[0026] On the top of the pressing plate 303, a limiting column 305 is fixedly connected, and the limiting column 305 penetrates through the top of the barrel 1. One-way valves are arranged in the inner cavities of the air inlet pipe 101, the gas inlet pipe 102, and the outlet pipe 103;

[0027] It should be noted that: When the second servo motor 301 is turned on, the second servo motor 301 drives the second rotating shaft 302 to rotate, and the second rotating shaft 302 drives the stirring plate 304 to rotate, thereby stirring and mixing the air and gas in the inner cavity of the barrel 1. And because the second rotating shaft 302 and the pressing plate 303 are threadedly connected, and with the limiting effect of the limiting column 305 on the top of the pressing plate 303, the pressing plate 303 can slide on the side wall of the second rotating shaft 302. Due to the setting of the one-way valve, when the pressing plate 303 slides downward, it squeezes the mixed gas in the inner cavity of the barrel 1 to reach the furnace body through the outlet pipe 103. When the pressing plate 303 slides upward, it accelerates the intake of the air inlet pipe 101 and the gas inlet pipe 102.

[0028] Refer to Figures 1 - 4, a first connecting plate 4 is fixedly connected to the end of the air inlet pipe 101, and a second connecting plate 401 is fixedly connected to the end of the filter box 201;

[0029] A threaded bolt 402 is threadedly connected to the side wall of the first connecting plate 4, and the first connecting plate 4 and the second connecting plate 401 are fixedly connected by the threaded bolt 402;

[0030] A collection box 403 is clamped to the bottom of the filter box 201 below the filter plate 202, and the collision block 208 is hemispherical;

[0031] It should be noted that: the air inlet pipe 101 and the filter box 201 are fixedly connected by the first connecting plate 4 and the second connecting plate 401 using the threaded bolt 402. Thus, by rotating the threaded bolt 402, the filter box 201 can be detached from the side wall of the air inlet pipe 101 for easy cleaning. Among them, the setting of the collision block 208 facilitates the rotation column 209 to collide with it, shaking the dust into the inner cavity of the collection box 403.

[0032] Operation method: Turn on the first servo motor 205 on the side wall of the mounting plate 204. The first servo motor 205 drives the first rotating shaft 206 to rotate, and the first rotating shaft 206 drives the fan blade 207 to rotate to form wind power, sucking air from outside the filter box 201 through the air inlet pipe 101 and then entering the barrel 1 cavity. And during the process of the air passing through the filter box 201, the dust existing inside it will be filtered by the filter plate 202, preventing the dust from entering the barrel 1 through the air inlet pipe 101 and then entering the furnace body, causing pollution. And during the rotation of the first rotating shaft 206, it will also drive the rotation column 209 to rotate. When the rotation column 209 rotates, it squeezes the filter plate 202 to slide through the collision block 208, thus causing the spring 203 between the filter plate 202 and the filter box 201 to be squeezed, forming a rebounding force. Through the rebounding force of the spring 203, the filter plate 202 vibrates, shaking the dust adsorbed on the surface of the filter plate 202 into the inner cavity of the collection box 403, preventing the dust from blocking the filter plate 202 and reducing the air intake, affecting combustion. Among them, rotating the threaded bolt 402 can detach the filter box 201 from the side wall of the air inlet pipe 101 for easy cleaning;

[0033] Turn on the second servo motor 301, and the second servo motor 301 drives the second rotating shaft 302 to rotate. The rotation of the second rotating shaft 302 drives the stirring plate 304 to rotate, thereby stirring and mixing the air and gas in the inner cavity of the barrel 1. And because the second rotating shaft 302 is threadedly connected to the pressing plate 303, and there is a limiting effect of the limiting column 305 on the top of the pressing plate 303, the pressing plate 303 can slide on the side wall of the second rotating shaft 302. Due to the setting of the one-way valve, when the pressing plate 303 slides downward, it squeezes the mixed gas in the inner cavity of the barrel 1 to reach the furnace body through the air outlet pipe 103. When the pressing plate 303 slides upward, it accelerates the intake of the air inlet pipe 101 and the gas inlet pipe 102.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
