[0001] The invention relates to the technical field of particle burners, in particular to an integrated electronically controlled burner. Background Art

[0002] Burner is a general term for devices that make fuel and air spray out in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, special burners according to their types and application fields, and burners that use biomass pellets as fuel are called pellet burners.

[0004] Although the above patents have proposed a technical solution to solve the dust cleaning problem, the following defects still exist:

[0005] The burner uses straw pellets as fuel, and the granular fuel is easy to accumulate at the bottom, resulting in incomplete combustion and insufficient contact with air, which ultimately leads to poor combustion effect.

[0006] Therefore, an integrated electronically controlled burner is proposed. Summary of the invention

[0007] The object of the present invention is to provide an integrated electronically controlled burner. By using an air intake drive mechanism, the combustion disk can be blown by air from bottom to top, and the combustion disk can be driven to rotate under the action of the airflow, so that the material on the combustion disk is scattered and supplemented with oxygen by sufficient airflow from below, so that it can burn better and effectively improve the combustion efficiency. By using a discharging mechanism, the ashes near the edge of the combustion disk can be discharged, and by using hinged doors and blocks arranged at intervals, the ashes can be discharged periodically, so that the ashes will not be piled up in the combustion disk, further improving the combustion efficiency, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solutions:

[0009] An integrated electronically controlled burner comprises a shell, a first connecting frame is fixedly connected in the shell, a second connecting frame is fixedly connected to the first connecting frame through a vertical plate, a combustion disk is installed on the top of the second connecting frame, a feed pipe is installed through one side of the shell, and an air intake drive mechanism is arranged in the second connecting frame;

[0010] The air intake drive mechanism includes an air inlet pipe, which is fixedly installed in a second connecting frame, and the air outlet of the air inlet pipe faces upward. Two mounting frames are fixedly connected to the inner wall of the second connecting frame, and shaft sleeves are fixedly installed on the two mounting frames. A connecting rod is fixedly connected between the two shaft sleeves. A combustion disk is fixedly connected to the top of the connecting rod, and the combustion disk is recessed downward. Vortex fan blades are fixedly sleeved on the connecting rod, and through holes are evenly opened on the bottom of the combustion disk. Discharging mechanisms are arranged around the top of the combustion disk, and a fly ash collection mechanism is arranged on the top of the inner wall of the shell.

[0011] The granular fuel is introduced into the shell through the feed pipe from the outside, and falls onto the combustion disk and rolls toward the center of the combustion disk. The air inlet pipe is connected to the external air source to generate wind force upwards. The wind force blows the vortex fan blades to rotate and drive the combustion disk to rotate together, so that the fuel that falls on the combustion disk is dispersed. By controlling the wind force of the wind blowing upwards from the through hole 8, the fuel on the combustion disk is subjected to the effect of downward air intake, which causes the fuel to have a flame spraying effect, thereby making it difficult for the granular fuel to accumulate. In addition, air intake from below can effectively increase the height of the flame and the combustion efficiency. The ashes brought out through the hinged door will fall into the gap between the first connecting frame and the second connecting frame and be caught by the receiving box. When there are too many ashes in the receiving box, the receiving box can be pulled out using the handle to take out the ashes.

[0012] Preferably, the discharging mechanism includes four blocks, which are evenly spaced on the shell. An annular frame is fixedly connected to the top of the combustion disk, and four hinged doors are evenly rotatably hinged on the annular frame, and the hinged doors are in contact with the blocks.

[0013] The fuel on the combustion disk continuously moves to the surroundings of the combustion disk as the combustion disk rotates. The closer the fuel is to the edge of the combustion disk, the higher the degree of combustion. As the combustion disk continuously rotates, the annular frame also rotates together with the combustion disk. The hinged door hinged on the annular frame opens outward under the action of centrifugal force, and the fuel that is burned out near the edge of the combustion disk can leave the combustion disk through the hinged door. During the rotation, the hinged door will contact the block and be blocked back into the annular frame by the block. As a result, the hinged door will open and close periodically under the action of the block, causing the fuel on the combustion disk to be discharged periodically, thereby reducing the adverse effects of ash accumulation on fuel combustion.

[0014] Preferably, the fly ash collection mechanism includes a blocking ring, which is fixedly mounted on the top of the inner wall of the shell, and an exhaust outlet is obliquely opened on the top of the shell, the port of the exhaust outlet is close to the blocking ring and the inclination angle of the exhaust outlet is consistent with that of the blocking ring, and an ash box is fixedly connected to the outer wall of the shell, a curved blocking portion is provided on the top of the ash box, and the bottom end of the curved blocking portion is close to the port of the exhaust outlet, and a filter is embedded in the outer plate of the ash box.

[0015] The fuel on the combustion disk continuously moves to the surroundings of the combustion disk as the combustion disk rotates. The closer the fuel is to the edge of the combustion disk, the higher the degree of combustion. The fuel with a high degree of combustion will produce a lot of debris or fragments during the movement, forming fly ash under the action of wind. These fly ashes are more close to the edge of the combustion disk. The wind below blows the fly ash upward and blows it to the angle between the blocking ring and the shell, and flies to the ash collecting box along the exhaust port. When the wind reaches the ash collecting box, it is changed in direction by the bent blocking part, making it downward and quickly reducing the wind speed to make the debris fall downward. In order to prevent the wind from generating turbulence in the ash collecting box, a filter is installed on the outer plate of the ash collecting box so that the wind can overflow from the filter to prevent debris from flying around in the ash collecting box.

[0016] Preferably, a soft cloth is fixedly installed in the dust collecting box near the bottom end of the air outlet, and one end of the soft cloth is fixedly connected to a brush.

[0017] Under the wind force flowing from the exhaust port, the soft cloth swings back and forth, causing the brush to continuously brush the surface of the filter to prevent fly ash from sticking to the filter and causing blockage.

[0018] Preferably, an outer plate of the ash collecting box is rotatably hinged with a rotating door, a second magnet is fixedly installed on the top of the filter screen of the ash collecting box, and a first magnet is fixedly connected to the bottom end of the rotating door.

[0019] When there is too much fly ash accumulated in the ash box, fold it upwards and adsorb the first magnet onto the second magnet. The rotating door will block the air outlet of the filter, and the airflow from the ash box will be blown out through the gap of the rotating door. At this time, you only need to use a bag to catch the blown fly ash.

[0020] Preferably, the air outlet is obliquely opened on the shell, and the edge of the air outlet faces the bottom end of the curved blocking portion.

[0021] The wind from below flies toward the ash collecting box along the exhaust port. When the wind reaches the ash collecting box, it is changed in direction by the curved blocking part, directed downward, and the wind speed is quickly reduced, causing the debris to fall downward, thereby improving the collection effect of the debris.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention uses an air intake drive mechanism to allow the combustion disk to be blown by air from bottom to top, and the combustion disk is driven to rotate under the action of the airflow, so that the material on the combustion disk is scattered and supplemented with oxygen by sufficient airflow from below, so that it can burn better and effectively improve the combustion efficiency.

[0024] 2. The present invention can discharge the ashes near the edge of the combustion tray by using a discharge mechanism, and can discharge the ashes periodically by using hinged doors and blocks arranged at intervals, so that the ashes will not be piled up in the combustion tray, further improving the combustion efficiency.

[0025] 3. The present invention uses a fly ash collection mechanism to collect the debris generated by the rolling of the burnt-out fuel near the edge of the combustion disk, so that it is blown to the ash box through the exhaust port, and uses soft cloth and rotating door mechanisms to keep the ash box clean and discharge dust.

[0035] See also Figures 1 to 5 The present invention provides an integrated electronically controlled burner, and the technical solution is as follows:

[0036] An integrated electronically controlled burner comprises a shell 1, a first connecting frame 2 is fixedly connected inside the shell 1, a second connecting frame 3 is fixedly connected to the first connecting frame 2 through a vertical plate, a combustion disk 7 is installed on the top of the second connecting frame 3, a feed pipe 10 is installed through one side of the shell 1, and an air intake drive mechanism is arranged inside the second connecting frame 3;

[0037] The air intake drive mechanism includes an air intake pipe 9, which is fixedly installed in the second connecting frame 3, with the air outlet of the air intake pipe 9 facing upward. Two mounting frames 4 are fixedly connected to the inner wall of the second connecting frame 3, and shaft sleeves 5 are fixedly installed on the two mounting frames 4. A connecting rod 24 is fixedly connected between the two shaft sleeves 5. The top of the connecting rod 24 is fixedly connected to a combustion disk 7, and the combustion disk 7 is recessed downward. Vortex fan blades 6 are fixedly sleeved on the connecting rod 24. Through holes 8 are evenly opened on the bottom of the combustion disk 7. Discharging mechanisms are arranged around the top of the combustion disk 7, and a fly ash collection mechanism is arranged on the top of the inner wall of the shell 1.

[0038] The granular fuel is introduced into the shell 1 through the feed pipe 10 from the outside, and falls onto the combustion disk 7 and rolls toward the center of the combustion disk 7. The air inlet pipe 9 is connected to the external air source to generate wind force upwards. The wind force blows the vortex fan blades 6 to rotate and drive the combustion disk 7 to rotate together, so that the fuel falling on the combustion disk 7 is dispersed, and by controlling the wind force of the wind blowing upwards from the through hole 8, the fuel on the combustion disk 7 is subjected to the effect of downward air intake, so that it produces the effect of flame spraying, so that the granular fuel is not easy to accumulate, and the air intake from below can effectively increase the height of the flame and the combustion efficiency. The ashes that fall out through the hinged door 11 will fall into the gap between the first connecting frame 2 and the second connecting frame 3, and be received by the receiving box 13. When there are too many ashes in the receiving box 13, the handle 14 is used to pull out the receiving box 13 to take out the ashes.

[0039] As an embodiment of the present invention, refer to Figure 1 and Figure 4 The discharging mechanism includes a stopper 12, the number of which is four. The stoppers 12 are evenly spaced on the shell 1. An annular frame 25 is fixedly connected to the top of the combustion disk 7. Four hinged doors 11 are evenly rotatably hinged on the annular frame 25, and the hinged doors 11 are in contact with the stoppers 12.

[0040] The fuel on the combustion disk 7 continuously moves to the surroundings of the combustion disk 7 as the combustion disk 7 rotates. The closer the fuel is to the edge of the combustion disk 7, the higher the degree of combustion. During the continuous rotation of the combustion disk 7, the annular frame 25 also rotates together with the combustion disk 7. The hinged door 11 hinged on the annular frame 25 opens outward under the action of centrifugal force, and the fuel that is burned out near the edge of the combustion disk 7 can leave the combustion disk 7 through the hinged door 11. During the rotation, the hinged door 11 will contact the block 12 and be blocked back into the annular frame 25 by the block 12, so that the hinged door 11 will periodically open and close under the action of the block 12, so that the fuel on the combustion disk 7 will be discharged periodically, reducing the adverse effect of ash accumulation on fuel combustion.

[0041] As an embodiment of the present invention, refer to Figure 1 and Figure 5 The fly ash collection mechanism includes a blocking ring 15, which is fixedly installed on the top of the inner wall of the shell 1. An exhaust port 16 is obliquely opened on the top of the shell 1. The port of the exhaust port 16 is close to the blocking ring 15 and the inclination angle of the exhaust port 16 is consistent with that of the blocking ring 15. An ash collecting box 17 is fixedly connected to the outer wall of the shell 1. A curved blocking portion 1701 is provided on the top of the ash collecting box 17. The bottom end of the curved blocking portion 1701 is close to the port of the exhaust port 16. A filter screen 18 is embedded in the outer plate of the ash collecting box 17.

[0042] The fuel on the combustion disk 7 is continuously moved to the surroundings of the combustion disk 7 under the rotation of the combustion disk 7. The closer the fuel is to the edge of the combustion disk 7, the higher the degree of combustion. The fuel with a high degree of combustion will produce a lot of debris or fragments during the movement, forming fly ash under the action of wind. These fly ashes are more close to the edge of the combustion disk 7. The wind below blows the fly ash upward and blows it to the angle between the blocking ring 15 and the shell 1, and flies to the ash collecting box 17 along the exhaust port 16. In order to prevent the wind from generating turbulence in the ash collecting box 17, a filter screen 18 is installed on the outer plate of the ash collecting box 17, so that the wind can overflow from the filter screen 18 to prevent debris from flying around in the ash collecting box 17.

[0043] As an embodiment of the present invention, refer to Figure 5 A soft cloth 22 is fixedly installed in the dust box 17 near the bottom of the air outlet 16, and a brush 23 is fixedly connected to one end of the soft cloth 22.

[0044] Under the force of wind flowing through the exhaust port 16 , the soft cloth 22 swings back and forth, causing the brush 23 to continuously brush the surface of the filter screen 18 , thereby preventing fly ash from adhering to the filter screen 18 and causing blockage.

[0045] As an embodiment of the present invention, refer to Figure 5The outer side plate of the ash box 17 is rotatably hinged with a rotating door 19, the ash box 17 is located on the top of the filter screen 18 and is fixedly installed with a second magnet 21, and the bottom end of the rotating door 19 is fixedly connected with a first magnet 20.

[0046] When too much fly ash accumulates in the ash box 17, it is folded upward to adsorb the first magnet 20 onto the second magnet 21, so that the rotating door 19 blocks the air outlet of the filter 18, and the airflow of the ash box 17 will be blown out along the gap of the rotating door 19. At this time, you only need to use a bag to catch the blown fly ash.

[0047] As an embodiment of the present invention, refer to Figure 5 The air outlet 16 is obliquely opened on the housing 1 , and the edge of the air outlet 16 faces the bottom end of the curved blocking portion 1701 .

[0048] The wind from below flies along the exhaust port 16 toward the ash collecting box 17. When the wind reaches the ash collecting box 17, it is changed in direction by the curved blocking portion 1701, directed downward, and the wind speed is quickly reduced, causing the debris to fall downward, thereby improving the collection effect of the debris.

[0049] Working principle: the granular fuel is introduced into the shell 1 through the feed pipe 10 from the outside, and falls onto the combustion disk 7, rolling toward the center of the combustion disk 7. The air inlet pipe 9 is connected to the external air source to generate wind force upwards. The wind force blows the vortex fan blades 6 to rotate, and drives the combustion disk 7 to rotate together, so that the fuel that falls on the combustion disk 7 is dispersed, and by controlling the wind force of the wind blowing upwards from the through hole 8, the fuel on the combustion disk 7 is subjected to the effect of downward air intake, so that it produces the effect of spraying fire, so that the granular fuel is not easy to accumulate, and the air intake from below can effectively increase the height of the flame and the combustion efficiency.

[0050] The fuel on the combustion disk 7 continuously moves to the surroundings of the combustion disk 7 as the combustion disk 7 rotates. The closer the fuel is to the edge of the combustion disk 7, the higher the degree of combustion. During the continuous rotation of the combustion disk 7, the annular frame 25 also rotates together with the combustion disk 7. The hinged door 11 hinged on the annular frame 25 opens outward under the action of centrifugal force, and the fuel that is burned out near the edge of the combustion disk 7 can leave the combustion disk 7 through the hinged door 11. During the rotation, the hinged door 11 will contact the block 12 and be blocked back into the annular frame 25 by the block 12, so that the hinged door 11 will periodically open and close under the action of the block 12, so that the fuel on the combustion disk 7 will be discharged periodically, reducing the adverse effect of ash accumulation on fuel combustion.
