Description

Technical Field

[0001] The utility model relates to the technical field of combustion furnaces, in particular to a burner and a particle combustion furnace. Background Art

[0002] The combustion barrel in a pellet stove has ventilation holes. An electronic control unit controls the feeding mechanism to deliver biomass pellets into the barrel. Biomass fuel is a granular fuel made from processed straw and rice stalks. A fan blows air into the barrel through the ventilation holes, ensuring full combustion of the biomass pellets and meeting residential heating and living energy needs.

[0003] Existing pellet stoves cannot precisely adjust the air flow rate by adjusting the fan speed alone, making it difficult to accurately control the combustion conditions within the combustion barrel. For example, when used as a barbecue, the pellet stove cannot precisely control the combustion of biomass pellets within the combustion barrel, making it impossible to precisely adjust the amount of smoke produced, making it difficult to meet the user's demand for a smoky flavor. Furthermore, the pellet stove will not extinguish until all the biomass pellets remaining in the combustion barrel are completely burned, resulting in a prolonged extinguishing time. Utility Model Content

[0004] One of the technical problems solved by the present invention is to provide a burner that can effectively solve the technical problems existing in the prior art of being unable to accurately control the combustion condition of the burner and having a burner extinguishing time that is too long.

[0005] The second technical problem solved by the present invention is to provide a particle combustion stove, which can effectively solve the technical problems existing in the prior art of being unable to accurately control the combustion condition of the burner and the burner extinguishing time being too long.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] Burner, including:

[0008] an inner barrel, wherein a first air hole is formed on a side wall of the inner barrel;

[0009] An outer barrel, wherein a second air hole is provided on the side wall of the outer barrel, and the outer barrel is coaxially sleeved on the outer side of the inner barrel; one of the inner barrel and the outer barrel can be axially rotated relative to the other to adjust the overlapping area of the first air hole and the corresponding second air hole, thereby adjusting the ventilation area of the inner barrel.

[0010] Compared with the background technology, the burner of the present invention has the following beneficial effects:

[0011] In the burner, an outer barrel is coaxially sleeved onto the outer side of an inner barrel. The inner barrel's sidewall is provided with a first air hole, and the outer barrel's sidewall is provided with a second air hole. When one of the inner and outer barrels rotates axially relative to the other, the overlap area between the first and second air holes can be adjusted, thereby adjusting the ventilation area of the inner barrel. This allows for precise control of the air flow entering the inner barrel for combustion, allowing for flexible control of combustion conditions to meet diverse user needs. When the overlap area between the first and second air holes is zero (i.e., when the first and second air holes do not overlap), no air enters the inner barrel, enabling rapid burnout and shortening the time it takes for the burner to completely extinguish.

[0012] In one embodiment, the burner further comprises a bellows for conveying air to the inner barrel, and the inner barrel is fixedly mounted in the bellows;

[0013] The bottom wall of the bellows is provided with a through hole coaxial with the outer barrel, the inner side of the through hole is provided with a limiting flange extending toward the interior of the bellows, and the bottom of the outer barrel is rotatably provided on the inner side surface of the limiting flange.

[0014] In one embodiment, the burner further includes a rotating assembly, which is transmission-connected to the outer barrel via the through hole to drive the outer barrel to rotate axially relative to the inner barrel and has a closed position in which the first air hole and the corresponding second air hole do not overlap and a fully open position in which the first air hole and the corresponding second air hole completely overlap.

[0015] In one embodiment, the rotating assembly includes:

[0016] A support plate, part of which extends into the through hole and is connected to the bottom of the outer barrel,

[0017] A swing rod, another part of the support plate extends out of the through hole and is connected to the swing rod, and the swing rod drives the support plate and the outer barrel to rotate synchronously between the closed position and the fully open position.

[0018] In one embodiment, the support plate includes a supporting portion, a guiding portion and a connecting portion which are connected in sequence at an angle, the supporting portion is connected to the bottom of the outer barrel, the guiding portion abuts against the inner side of the through hole and can rotate along the inner side of the through hole, and the connecting portion is located outside the bellows and is connected to the rocker arm.

[0019] In one embodiment, the connecting portion is installed with a fixing plate, the fixing plate is provided with a slot, and one end of the rocker arm is mounted in the slot.

[0020] In one embodiment, the support portion is provided with at least two guide portions spaced apart along the circumferential direction.

[0021] The second technical problem mentioned above is solved by the following technical solution:

[0022] The particle combustion furnace comprises a furnace body and the above-mentioned burner installed in the furnace body.

[0023] Compared with the background technology, the particle combustion stove described in the utility model has the following beneficial effects:

[0024] In the burner, an outer barrel is coaxially sleeved onto the outer side of an inner barrel, with a first air hole formed in the sidewall of the inner barrel and a second air hole formed in the sidewall of the outer barrel. When one of the inner and outer barrels rotates axially relative to the other, the overlap area between the first and second air holes can be adjusted, thereby adjusting the ventilation area of the inner barrel. This allows for precise control of the air flow entering the inner barrel for combustion, allowing for flexible control of combustion conditions according to user needs. When the overlap area between the first and second air holes is zero (i.e., when the first and second air holes do not overlap), no air enters the inner barrel, enabling rapid burnout and shortening the time it takes for the burner to completely extinguish.

[0025] In one embodiment, a limiting groove is provided on the furnace body, and a handle is formed at one end of the rocker arm of the burner away from the support plate of the burner. The handle passes through the limiting groove and extends out of the furnace body.

[0026] In one embodiment, the handle swings along the length direction of the limit slot, and when the handle swings to one end of the length direction of the limit slot, it is in a closed position, and the first air hole and the corresponding second air hole do not overlap; when the handle swings to the other end of the length direction of the limit slot, it is in a fully open position, and the first air hole and the corresponding second air hole completely overlap.

[0034] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the present invention are further described below with reference to the accompanying drawings and through specific embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of it.

[0035] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0036] In the description of this embodiment, terms such as "upper," "lower," "right," and "left" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1 As shown, this embodiment proposes a pellet combustion furnace, which includes a furnace body 6 and a burner installed in the furnace body 6, an electronic control device and a feeding mechanism 9 (generally a spiral feeding device), and the electronic control device controls the feeding mechanism 9 to transport biomass particles into the burner.

[0039] Existing burners contain a combustion barrel with ventilation holes, through which air enters the barrel, allowing biomass fuel to burn, thereby meeting civilian heating and household energy needs. Existing burners struggle to precisely control the combustion within the barrel. For example, when a pellet stove is used as a barbecue, it's impossible to precisely control the combustion of the biomass pellets within the barrel, making it impossible to precisely adjust the amount of smoke produced, making it difficult to satisfy users' desire for a smoky flavor. Furthermore, the remaining biomass pellets in the barrel need to be completely burned before the stove gradually extinguishes, resulting in a prolonged extinguishing time for the pellet stove.

[0040] To solve the above problems, Figure 1 and Figure 2 As shown, this embodiment also provides a burner comprising an inner barrel 1 and an outer barrel 2. The inner barrel 1 has a first air hole 11 defined in its sidewall. The outer barrel 2 has a second air hole 21 defined in its sidewall. The outer barrel 2 is coaxially sleeved on the outer side of the inner barrel 1. One of the inner barrel 1 and the outer barrel 2 can rotate axially relative to the other to adjust the overlap between the first air hole 11 and the corresponding second air hole 21, thereby adjusting the ventilation area of the inner barrel 1. Axial rotation of either the inner barrel 1 or the outer barrel 2 adjusts the overlap between the first air hole 11 and the corresponding second air hole 21, thereby adjusting the ventilation area of the inner barrel 1. This allows for precise control of the air flow entering the inner barrel 1 for combustion, allowing for flexible control of the combustion conditions of the inner barrel 1 to meet the diverse needs of users. When the overlapping area of the first air hole 11 and the corresponding second air hole 21 is zero, that is, when the first air hole 11 and the corresponding second air hole 21 do not overlap, no air enters the inner barrel 1, so that the burner can be extinguished quickly, shortening the time for the burner to be completely extinguished.

[0041] It should be noted that the sidewall of the inner tub 1 is uniformly distributed with a plurality of first air holes 11. The sidewall of the outer tub 2 is uniformly distributed with a plurality of second air holes 21. The number of first air holes 11 and second air holes 21 is the same, and both are circular holes. The diameters of the first air holes 11 and the second air holes 21 are equal, that is, the opening areas of the first air holes 11 and the second air holes 21 are equal. In other embodiments, the first air holes 11 and the second air holes 21 can also have other shapes, such as square, oval, etc.

[0042] In this embodiment, the inner barrel 1 is fixedly mounted within the furnace body 6, while the outer barrel 2 is axially rotatable relative to the inner barrel 1. The burner also includes a bellows 3 for supplying air to the inner barrel 1, with the inner barrel 1 fixedly mounted within the bellows 3. A blower 8 is mounted externally to the bellows 3, conveying external air into the inner barrel 1 through the bellows 3. In other embodiments, the outer barrel 2 is fixedly mounted within the furnace body 6, while the inner barrel 1 is axially rotatable relative to the outer barrel 2. Depending on the rotation angle of the outer barrel 2, the first air holes 11 and the second air holes 21 may completely overlap, partially overlap, or not overlap at all. When the first air holes 11 and the second air holes 21 completely overlap, they correspond to each other and are coaxially arranged. At this point, the first air holes 11 are fully open, and the ventilation area of the inner barrel 1 is equal to the sum of the opening areas of all the first air holes 11. At this point, the air flow rate entering the inner barrel 1 is maximized. When the first air holes 11 and the second air holes 21 partially overlap, they are eccentrically positioned. In this case, the first air holes 11 are partially open, and the ventilation area of the inner tub 1 is the sum of the overlapping areas of all first air holes 11 and second air holes 21. When the first air holes 11 and the second air holes 21 do not overlap at all, the sidewalls of the outer tub 2 completely block the first air holes 11. In this case, the first air holes 11 are closed, the ventilation area of the inner tub 1 is zero, and no air enters the inner tub 1.

[0043] like Figure 1 and Figure 2 As shown, the bottom wall of the bellows 3 is provided with a through hole 31 coaxial with the outer tub 2. A limiting flange 32 extends from the inner side of the through hole 31 toward the interior of the bellows 3. The bottom of the outer tub 2 is pivotally mounted on the inner side of the limiting flange 32. The outer tub 2 is supported and mounted on the inner side of the limiting flange 32, ensuring stable support and circumferential positioning of the outer tub 2, preventing displacement during axial rotation of the outer tub 2.

[0044] It should be noted that if Figure 2 and Figure 3 As shown, the through hole 31 is provided with multiple limiting flanges 32 spaced circumferentially. These flanges 32 define a space for accommodating the outer tub 2, ensuring stable rotation of the outer tub 2. The spaced arrangement of the multiple limiting flanges 32 reduces the difficulty of manufacturing them and reduces the contact area between the flanges 32 and the bottom of the outer tub 2, thereby reducing friction between the flanges 32 and the outer tub 2 and facilitating smooth rotation of the outer tub 2. Furthermore, the circular arc structure of the bottom edge of the outer tub 2 reduces the contact area between the flanges 32 and the bottom of the outer tub 2, further reducing friction between the flanges 32 and the outer tub 2 and ensuring smooth rotation of the outer tub 2.

[0045] like Figure 3As shown, the burner also includes a rotating assembly, which is transmission-connected to the outer barrel 2 via a through-hole 31. This assembly drives the outer barrel 2 to rotate axially relative to the inner barrel 1, with the outer barrel 2 having a closed position in which the first air holes 11 and the corresponding second air holes 21 do not overlap, and a fully open position in which the first air holes 11 and the corresponding second air holes 21 completely overlap. The rotating assembly drives the outer barrel 2 to rotate, making it easy and flexible to rotate the outer barrel 2, allowing for quick adjustment of the overlap area between the first air holes 11 and the corresponding second air holes 21 to precisely control the air flow entering the inner barrel 1. It should be noted that the outer barrel 2 can be rotated to a closed position, a fully open position, or any position between the closed and fully open positions to adjust the air flow within the inner barrel 1.

[0046] Specifically, the rotating assembly includes a support plate 4 and a rocker arm 5. A portion of the support plate 4 extends into the through-hole 31 and connects to the bottom of the outer tub 2. The remaining portion of the support plate 4 extends out of the through-hole 31 and connects to the rocker arm 5, which drives the support plate 4 and the outer tub 2 to rotate synchronously between a closed position and a fully open position. Manually shifting the rocker arm 5 drives the support plate 4 and the outer tub 2 to rotate synchronously between the closed and fully open positions, allowing the first air hole 11 and the second air hole 21 to be in any of a variety of states: fully overlapped, partially overlapped, or completely non-overlapped. Manually shifting the rocker arm 5 is simple and easy, allowing users to flexibly and quickly adjust the air flow in the inner tub 1 according to their needs. This eliminates the need for an additional drive mechanism and simplifies the structure of the rotating assembly.

[0047] like Figure 3 As shown, the support plate 4 includes a support portion 41, a guide portion 42, and a connecting portion 43, which are connected at an angle. The support portion 41 is connected to the bottom of the outer tub 2, the guide portion 42 abuts the inner side of the through-hole 31 and can rotate along the inner side of the through-hole 31, and the connecting portion 43 is located outside the bellows 3 and connected to the rocker arm 5. In this embodiment, the support portion 41, the guide portion 42, and the connecting portion 43 are all plate-shaped structures. The support portion 41 is welded to the bottom of the outer tub 2, and the guide portion 42 contacts the inner side of the through-hole 31 (and part of the limiting flange 32). When the support plate 4 rotates synchronously with the outer tub 2, the guide portion 42 rotates along the inner side of the through-hole 31, so that the through-hole 31 guides and limits the rotation of the support plate 4 and the outer tub 2, ensuring the stability and reliability of the outer tub 2 during rotation.

[0048] In one embodiment, the support portion 41 is provided with at least two guide portions 42 spaced apart along the circumference. The provision of multiple guide portions 42 further enhances the guiding and retaining effect of the guide portions 42 on the outer tub 2, ensuring more stable rotation of the outer tub 2. In this embodiment, the support portion 41 is provided with two guide portions 42 symmetrically distributed along the circumference. Each guide portion 42 is connected to a connecting portion 43 at an angle at one end distal from the support portion 41. Because the angles between each of the support portion 41, the guide portions 42, and the connecting portion 43 are all right angles, the support plate 4 forms a "J" shape. The support portion 41 and the two guide portions 42 extend into the through hole 31. The two connecting portions 43 are located outside the bellows 3, with a gap between them to prevent friction between the connecting portions 43 and the bellows 3, which could hinder normal rotation of the outer tub 2.

[0049] like Figure 3 As shown, one of the connecting portions 43 is detachably connected to the rocker arm 5, facilitating assembly and disassembly of the rotating assembly and improving the efficiency of assembly and disassembly of the rotating assembly. Specifically, the connecting portion 43 is mounted with a fixing plate 44, which defines a slot 441 into which one end of the rocker arm 5 is snap-fitted. The snap-fit connection between the rocker arm 5 and the fixing plate 44 improves the efficiency and strength of the installation of the rocker arm 5 and the connecting portion 43. The support portion 41, guide portion 42, connecting portion 43, and fixing plate 44 are integrally formed by bending, making the support plate 4 a single, integral component, thereby improving the structural strength of the support plate 4.

[0050] In this embodiment, a fixing plate 44 is provided at each end of the connecting portion 43 in the width direction. Both fixing plates 44 are provided with a slot 441, and one side of the fixing plate 44 has an opening for the slot 441. The swing arm 5 extends through the opening of the slot 441 into the slot 441, so that the swing arm 5 is simultaneously engaged with both slots 441, further improving the installation strength of the swing arm 5 and the connecting portion 43. Specifically, the end of the swing arm 5 that engages the fixing plate 44 is a screw, which engages with the two slots 441 and then extends out of the two slots 441, and finally engages with a nut to lock the swing arm 5 in the two slots 441.

[0051] like Figure 4 and Figure 5 As shown, the furnace body 6 is provided with a limit slot 61. The end of the burner's swing arm 5, away from the burner's support plate 4, forms a handle 51. The handle 51 passes through the limit slot 61 and extends out of the furnace body 6. The handle 51 formed at one end of the swing arm 5 facilitates the user's grip when adjusting the rotational position of the outer barrel 2, enhancing the user experience. Furthermore, since the handle 51 extends outside the furnace body 6, the user can operate the swing arm 5 without opening the furnace body 6, preventing burns and other injuries caused by the high temperature of the furnace body 6. This improves the efficiency of regulating the air flow in the inner barrel 1 and the safety of the pellet burner.

[0052] Specifically, the handle 51 swings along the length of the limit slot 61. When the handle 51 swings to one end of the limit slot 61, it is in the closed position, and the first air hole 11 does not overlap with the corresponding second air hole 21. When the handle 51 swings to the other end of the limit slot 61, it is in the fully open position, and the first air hole 11 completely overlaps with the corresponding second air hole 21. The limit slot 61 limits and guides the swing position of the handle 51, allowing the handle 51 to stay in the closed position, the fully open position, and any position between the closed and fully open positions. This achieves flexible adjustment of the air flow in the inner barrel 1, while ensuring that the handle 51 moves accurately to the closed and fully open positions, improving the adjustment precision and accuracy.

[0053] In this embodiment, along Figure 4 In the direction indicated by the middle arrow, when the grip handle 51 is moved to one end of the limiting groove 61, the first air hole 11 does not overlap with the corresponding second air hole 21, and the side wall of the outer barrel 2 completely blocks the first air hole 11. The first air hole 11 is closed, and no air enters the inner barrel 1 at this time. Figure 5 When the handle 51 is moved to the other end of the limiting slot 61 in the direction indicated by the middle arrow, the first air hole 11 completely overlaps with the second air hole 21, and the first air hole 11 is fully open. At this time, the air flow rate entering the inner tub 1 is maximized. When the handle 51 is positioned between the two ends of the limiting slot 61 in the longitudinal direction, the first air hole 11 partially overlaps with the second air hole 21, and the first air hole 11 is partially open. The air flow rate entering the inner tub 1 is between zero and the maximum air flow rate.

[0054] It should be noted that if Figures 1 to 5 As shown, the inner barrel 1 and the outer barrel 2 are also equipped with a heating rod 7. When the heating rod 7 is powered on, it heats and ignites the biomass pellets entering the inner barrel 1 to achieve normal combustion of the pellet burner. The heating rod 7 is fixedly installed at the bottom center of the inner barrel 1, and the outer barrel 2 and the support portion 41 are both provided with a clearance hole. The heating portion of the heating rod extends into the interior of the inner barrel 1, and the rest of the heating rod passes through the clearance holes of the outer barrel 2 and the support portion 41 in turn and is connected to the power supply wire. The power supply provides stable power to the heating rod 7 through the wire.

[0055] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments. Various changes and modifications are possible without departing from the spirit and scope of the present invention. Such changes and modifications are within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
