DETAILED DESCRIPTION

[0040] The principles and characteristics of the utility model are described below in combination with the drawings, and the examples are only used to explain the utility model and not used to limit the scope of the utility model.

[0041] Embodiment 1

[0042] As Figures 1-10As shown, the embodiment provides a wood-burning gasifier assembly, which comprises a grate 11, a bushing 12 and a hearth 13, the grate 11 is in the shape of a groove, the bushing 12 and the hearth 13 are both in the shape of a ring cylinder, the bushing 12 is placed on the upper end of the grate 11, the hearth 13 is placed on the upper end of the bushing 12, and the grate 11, the bushing 12 and the hearth 13 jointly form a combustion chamber 14, the combustion chamber 14 is provided with a wood inlet 15 on the side wall, the outer wall of the grate 11 is provided with a plurality of first air supply channels for air supply from bottom to top in a ring direction, the outer wall of the bushing 12 is provided with a plurality of second air supply channels for air supply from bottom to top in a ring direction, and the hearth 13 and the bushing 12 are provided with a plurality of third air supply channels in a ring direction, which are in communication with the combustion chamber 14, the first air supply channels, the second air supply channels and the third air supply channels are one-to-one corresponding, the upper end of each first air supply channel is in communication with the lower end of the corresponding second air supply channel, and the upper end of each second air supply channel is in communication with the outer end of the corresponding third air supply channel, so that wood can be put into the combustion chamber through the wood inlet, and pyrolysis gasification of the wood can be carried out in the grate to form combustible gas, and the combustible gas can be mixed with secondary air in the hearth and burn in the form of open fire, which has good combustion effect, wherein the first air supply channels, the second air supply channels and the third air supply channels are used to supply secondary air into the hearth, and the secondary air is supplied from the outside of the grate and the bushing, so that the effect of wood pyrolysis gasification can not be affected by excessive primary air supplied in the grate.

[0043] Specifically, as Figure 2 and Figure 3As shown, the grate 11 includes a grate cylinder 111 and a grate base plate 112. The grate cylinder 111 is vertically arranged, and its lower end is turned inward to form a support ring 1111. The grate base plate 112 rests on the grate cylinder 111. The upper end of the side wall of the grate cylinder 111 is recessed with a first fuel inlet notch 1112. Multiple air inlet grooves A1113, with their lower ends penetrating through the grate cylinder 11, are recessed circumferentially on the outer side of the grate body at intervals. The air inlet grooves A1113 penetrate the interior of the grate cylinder 111. The air inlet groove A1113 corresponding to the first fuel inlet notch 1112 is the first air inlet groove A1113a, and the remaining air inlet grooves A1113 are the second air inlet grooves A1113b. The top of 13b is provided with an air supply hole 1114 that penetrates the upper end of the grate cylinder 111. The air supply hole 1114 and the corresponding second air inlet groove A1113b together constitute the first air supply channel, so that the air volume is supplied upward through the air inlet groove A from bottom to top. A part of the air volume enters the grate from the side wall of the grate through the air inlet groove A to supply the combustible gas produced by the pyrolysis and gasification of the firewood for combustion (another part of the air volume enters the furnace surface through the first air supply channel, the second air supply channel and the third air supply channel). In addition, some primary air also enters the grate from the bottom plate of the grate. However, as the ash accumulation in the grate increases, this part of the primary air will gradually decrease in the later stage. This is also conducive to the pyrolysis and gasification of firewood in a high temperature and oxygen-deficient environment to produce combustible gas.

[0044] In this embodiment, the upper end of the second air inlet groove A is connected to the upper end of the grate cylinder through the corresponding air supply hole. As for the first air inlet groove A, the airflow it enters will enter the grate and will not continue to flow upward.

[0045] like Figure 4 As shown in the above technical solution, multiple cleaning scrapers 1121 are arranged circumferentially at the upper edge of the grate bottom plate 112. The grate bottom plate 112 is placed in the hole of the support ring 1111 and supported on the support ring 1111 by the multiple cleaning scrapers 1121. By setting multiple cleaning scrapers, the grate bottom plate can be hooked on the support ring by the multiple cleaning scrapers. At the same time, when the grate bottom plate rotates relative to the grate cylinder, the cleaning scrapers can push the ash from the inner edge of the grate to the lower end of the air inlet slot A and discharge it to the outside of the grate.

[0046] The grate provided by the embodiment can be improved on the basis of the pot-shaped biomass gasification grate disclosed in the document CN 219995349 U "A pot-shaped biomass gasification grate, a heating stove and a heating dining table". In addition, the grate bottom plate in the embodiment is uniformly provided with straight strip-shaped ash falling holes 1122 (which helps the wood to be quickly ignited, and after the wood is burned for a period of time, the falling ash covers the ash falling holes to block them, thereby reducing the air volume of the primary air), and the lower end of the grate bottom plate can be provided with a protruding block 1123. The protruding block can be used to drive the grate bottom plate to rotate in a small range by means of a tool (a special ash cleaning rod can be provided for use) from below the grate bottom plate to accelerate the ash removal. Specifically, the lower end of the air inlet groove A can extend to the edge of the supporting ring (as shown in Figure 5 , that is, the lower end of the air inlet groove A is bent to gather at the supporting ring, and penetrates the upper and lower ends of the supporting ring), and the grate bottom plate is hung on the supporting ring by the ash cleaning scraper. When the grate bottom plate is rotated at a small angle relative to the grate cylinder, the ash on the grate bottom plate is mainly removed through the ash falling holes, and the ash at the inner edge of the grate (that is, the ash on the supporting ring) is mainly removed through the lower end of the air inlet groove A under the driving of the ash cleaning scraper. The ash removal effect is good (wherein, when the grate bottom plate rotates, the ash cleaning scraper thereon has a tangential pushing action on the ash on the supporting ring to push the ash to the lower end of the air inlet groove A, and the ash cleaning scraper can exert a shearing force on the ash at this position to extrude the ash downward through the lower end of the air inlet groove A, thereby achieving ash removal. When the grate bottom plate rotates, the ash at the middle part of the upper end thereof can also be better removed through the ash falling holes).

[0047] As shown in Figure 2 and Figure 6 , the upper end face of the grate cylinder 111 in the above technical solution is a first inclined face 1115, the lower end of the bushing 12 is a second inclined face 121, and the first inclined face 1115 and the second inclined face 121 are embedded in each other (that is, they are inserted into each other). In this way, the grate and the bushing can be embedded in each other, thereby avoiding displacement of the grate and the bushing.

[0048] As shown in Figure 6 , the lower end of the bushing 12 in the above technical solution is provided with a second wood feeding gap 122, and the second wood feeding gap 122 and the first wood feeding gap 1112 are aligned with each other and jointly constitute the wood feeding port 15. The structure is simple, which makes the opening of the entire wood feeding port larger, and is beneficial to the wood feeding into the grate.

[0049] As shown in Figure 6 and Figure 7As shown in the technical scheme, the outer wall of the liner 12 is vertically provided with air inlet grooves B123, the air inlet grooves B123 at the second wood gap are first air inlet grooves B123a, the remaining air inlet grooves B123 are second air inlet grooves B123b, the second air inlet grooves B123b and the air supply holes 1114 one-to-one correspond, the lower end of each second air inlet groove B123b is aligned with the corresponding air supply hole 1114, and each second air inlet groove B123b forms a second air supply channel. The structure is simple, and the second air inlet grooves B on the outer wall of the liner form the second air supply channel, which is relatively simple to process. When the distance between the upper end of the second wood gap and the top of the liner is too small, the first air inlet grooves B can not be provided.

[0050] As shown in the technical scheme, Figure 8 and Figure 9 As shown in the technical scheme, the furnace surface 13 includes a furnace surface upper portion 131 and a furnace surface lower portion 132, the furnace surface upper portion 131 and the furnace surface lower portion 132 are both in a trumpet shape, the smaller opening end of the furnace surface upper portion 131 is butted with the smaller opening end of the furnace surface lower portion 132, the side wall of the furnace surface upper portion 131 is provided with an exhaust hole 1311, the inner wall of the furnace surface lower portion 132 is circumferentially and spacedly provided with a plurality of same-direction inclined guide vanes 1321, the upper end of the liner 12 is circumferentially and spacedly recessed with a plurality of same-direction inclined guide grooves 124, each air inlet groove B123 is aligned with a guide groove 124, the furnace surface 13 is placed on the upper end of the liner 12, and each guide vane 1321 extends into a guide groove 124, and each guide groove 124 aligned with the second air inlet groove B123b forms a third air supply channel. In this way, the furnace surface lower portion can be engaged with the guide grooves at the upper end of the liner through the guide vanes, so as to avoid displacement and misalignment of the two, in addition, the secondary air can enter the inner upper portion of the combustion chamber (i.e., the furnace surface) through the guide grooves, and the secondary air is in a rotational flow state under the action of the guide vanes, so that the secondary air can be fully mixed with the combustible gas generated by the wood pyrolysis, so that the combustible gas is in a rotational flow state and burns violently and sufficiently in the furnace surface.

[0051] In the embodiment, the exhaust hole 1311 at the side wall of the furnace surface upper portion 131 is a straight strip-shaped hole and is circumferentially and spacedly distributed.

[0052] In the embodiment, the guide vanes and the guide grooves do not need to one-to-one correspond, but each guide vane needs to correspond to a guide groove, and each guide groove can correspond to at most one guide vane, so that some guide grooves can not correspond to guide vanes.

[0053] In the embodiment, the fuel can be wood, carbon blocks or compressed biomass granules, and is not limited thereto.

[0054] The function of the bushing in this embodiment is mainly as a secondary air inlet channel and isolates the flame in the furnace body to prevent high temperature from damaging the furnace body.

[0055] The ash falling hole in this embodiment can adopt a narrow strip-shaped hole, so that after the wood is ignited, the ash produced will gradually block the ash falling hole, at this time the air volume of the primary air is reduced, and the fuel is pyrolyzed and gasified in a high temperature and oxygen deficient state, the combustible gas produced is mixed and burned with the air introduced into the grate through the air inlet channel A, thereby realizing gasification combustion.

[0056] As shown in Figure 11 The wood gasification heating stove (which can be used as a heating stove) provided in this embodiment includes a furnace body 2 and a wood gasification baffle assembly 1 as described in Embodiment 1, the wood gasification baffle assembly 1 is arranged above in the furnace body 2, the lower part of the furnace body 2 below the wood gasification baffle assembly 1 is an ash falling chamber 21, a dust removal port 22 in communication with the ash falling chamber 21 is arranged on the side wall of the furnace body 2, an annular flue gas discharge chamber 23 is formed by the surrounding of the furnace body 2 and the furnace surface 13, a chimney 24 in communication with the flue gas discharge chamber 23 is arranged at the upper end of the furnace body 2, a wood delivery port 25 is arranged at the position corresponding to the wood delivery port 15 of the furnace body 2, and a first opening and closing door 26 is arranged at the wood delivery port 25, which has a simple structure, the first opening and closing door can be closed after the wood is delivered, so that the air enters the ash falling chamber through the dust removal port and flows upward to form primary air and secondary air. The chimney 24 in this embodiment can be arranged on the side wall of the furnace body.

[0057] The dust removal port 22 in the above technical solution is provided with a second opening and closing door 28 which can be opened or closed, the second opening and closing door 28 is provided with an air volume adjusting member 29, the air volume adjusting member 29 can adjust the air inlet volume when the second opening and closing door is in a closed state, so that the second opening and closing door can be closed, and the air volume entering the ash falling chamber is adjusted through the air volume adjusting member.

[0058] The air volume adjusting member in this embodiment includes a sliding plate 291 and a pushing tooth 292, the second opening and closing door is provided with a breathable hole 281 (the breathable hole can be a strip-shaped hole, and multiple breathable holes can be arranged side by side), the sliding plate is slidingly arranged on the second opening and closing door, the pushing tooth is arranged on the sliding plate, the pushing tooth is manually pushed to drive the sliding plate to slide on the second opening and closing door to adjust the air permeability of the breathable hole (mainly the part of the sliding plate covers the breathable hole or completely covers the breathable hole, the air permeability of the breathable hole depends on the area size of the position where the breathable hole is not covered by the sliding plate), the pushing tooth is arranged on the side of the sliding plate corresponding to the outside of the furnace body.

[0059] The wood-fired gasification heating furnace provided in this embodiment, for easier operation, only has a vent hole (as an air inlet) on the second opening and closing door, and an air volume regulating component 29 for adjusting the opening and closing of the vent hole is provided above the second opening and closing door (that is, for the entire furnace body, it has only one air inlet). At this time, the combustion speed of the fuel in the furnace body can be easily controlled. The air volume entering the furnace body can be divided into primary air and secondary air under the action of the grate. When the fuel is burning normally, the proportion of primary air is larger and the proportion of secondary air is smaller. When there is more fuel or ash in the grate, the primary air will gradually decrease and the secondary air will gradually increase. The total air volume will not decrease, thereby ensuring that there is sufficient oxygen to enter the combustion chamber, so that the combustible gas produced by fuel pyrolysis can be fully burned in the combustion chamber.

[0060] Example 3

[0061] Same as Example 2, except that, as Figure 12 As shown, this embodiment provides a cooking stove, which expands the stove opening at the upper end of the stove body outward to form a trumpet-shaped pot opening 210 (with the larger opening facing upward).
