Description

Technical Field

[0001] The utility model relates to the technical field of biomass particle stoves, in particular to a stove core of a biomass particle stove. Background Art

[0002] Biomass pellet stove is an efficient and environmentally friendly heating device that uses biomass energy (such as pellet fuel formed by compression of agricultural and forestry waste such as wood chips, straw, and rice husks) as a heat source. It is suitable for a variety of scenarios such as home heating, hot water supply, and commercial heating.

[0003] The biomass pellet stove has an ignition device installed at the bottom of the stove core, and a feeding mechanism for adding fuel is installed in the middle of the stove core. When in use, fuel is added in the stove core, and the ignition is performed through the igniter when the fuel is added. After the ignition is successful, the biomass pellet stove starts to burn normally. However, there are two problems with the current biomass pellet stoves. First, the biomass pellet stove may fail to ignite during use. If the ignition fails, the biomass pellet fuel added to the stove core by the feeding mechanism will accumulate in the stove core. The accumulated biomass pellet fuel will affect the effect of the next ignition because it occupies too much space. Therefore, in order to ensure that the next ignition can be successful, it is necessary to manually take out the biomass pellets in the stove core and then ignite them. This method of taking out biomass pellet fuel is not only inefficient, but also the dust in the stove core is easy to dirty the arms and clothes.

[0004] Second, during the combustion process of biomass pellet fuel, since biomass fuel contains relatively high potassium, sodium, silicon and other elements, these elements make the melting point of ash relatively low. When the combustion temperature reaches 500-600℃, the ash begins to melt and stick. Above this temperature range, especially in the local high temperature area in the furnace core, the molten ash will form a eutectic. After cooling, the fuel ash hardens into a glassy hard block, which is the so-called coking or agglomeration. However, the furnace bridge of the existing biomass pellet furnace is mainly as follows: Figure 1 As shown in the fence shape, the coked or agglomerated fuel ash cannot be discharged from the furnace core through the gap of the furnace bridge due to its size, resulting in difficulty in ash discharge. In order to make the coked or agglomerated fuel ash fall from the furnace bridge, it is necessary to use a tool to break the agglomerated fuel ash and let it fall from the gap of the furnace bridge. The whole operation and breaking process is not only troublesome, but also the tool may cause damage to the furnace core. Utility Model Content

[0005] The utility model aims to provide a furnace core of a biomass particle stove, so as to solve the problem that fuel ash in the furnace core of the existing biomass particle stove is difficult to discharge after being agglomerated.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a furnace core of a biomass pellet stove, comprising a furnace core body, a base and an ash discharge mechanism;

[0007] The furnace core body is installed on the base, and a discharge port is provided at the bottom of the furnace core body, and the discharge port is communicated with the interior of the base;

[0008] The ash discharge mechanism is installed at the bottom end of the furnace core body in a transverse sliding manner. When the fuel in the furnace core is burning, the ash discharge mechanism is located directly below the discharge port to cover the discharge port. The fuel in the furnace core is supported and supported by the ash discharge mechanism to allow the fuel in the furnace core to stay and burn in the furnace core. When biomass particles or agglomerated fuel ash needs to be discharged, the ash discharge mechanism is slid transversely to expose the discharge port, and the biomass particles in the furnace core fall into the base through the discharge port under the action of gravity, or the agglomerated fuel ash is tapped with a tool, and then the fuel ash falls into the base through the discharge port under the action of gravity.

[0009] The working principle of the utility model is as follows: initially, the ash discharge mechanism is located directly below the discharge port to block the discharge port. After the ignition fails and a large number of biomass particles are piled in the furnace core, the ash discharge mechanism is pulled and the ash discharge mechanism slides horizontally. At this time, the ash discharge mechanism no longer blocks the discharge port. At this time, the biomass particles in the furnace core are discharged from the furnace core through the discharge port under the action of gravity and fall into the base, completing the discharge of the biomass particles in the furnace core when the ignition fails. After the biomass particle fuel in the furnace core is burned and used, the fuel ash generated by the biomass particle fuel in the furnace core is fused into a mass due to the high temperature. The massed fuel ash cannot be discharged normally through the ash discharge because of its large volume. At this time, the ash discharge mechanism is pulled horizontally to expose the discharge port. At this time, a tool is used to poke the massed fuel ash downward, and the fuel ash is broken into relatively small fuel ash. At this time, the volume of the fuel ash is reduced, and then it falls into the base through the discharge port under the action of gravity.

[0010] Beneficial effects of the utility model:

[0011] 1. After the furnace core fails to ignite, this solution can use the horizontally sliding ash discharge mechanism to expose the discharge port connected to the inside of the furnace core, so that the unburned biomass particles can be quickly discharged from the furnace core through the discharge port, providing convenience for secondary ignition. Not only does it improve the efficiency of secondary ignition, but it also does not require manual hands to reach into the furnace core to take out the biomass particles, avoiding the situation where the arms and clothes are dirty when manually taking out the biomass particles.

[0012] 2. When discharging the agglomerated fuel ash from the furnace core, you only need to poke the fuel ash to split it into relatively small fuel ash, and then it can be quickly and effectively discharged through the discharge port exposed by the ash discharge mechanism sliding horizontally. Compared with the existing furnace bridge, there will be no agglomerated fuel ash that cannot pass through the gap of the furnace bridge because the gap is too small, and it will not need to be broken up many times until it can pass through the gap of the furnace bridge, which greatly reduces the workload of the user when discharging the fuel ash, and also improves the convenience of discharging the agglomerated fuel ash.

[0013] Furthermore, the ash discharge mechanism includes an "E"-shaped furnace bridge, which is slidably connected to the bottom end of the furnace core in a transverse direction, and is located directly below the discharge port. A crossbar is fixedly connected to the furnace bridge, and one end of the crossbar away from the furnace bridge passes through the base and is located outside the base. The purpose is that by setting the "E"-shaped furnace bridge, the fine fuel ash will naturally pass through the gap in the furnace bridge under the action of gravity during the use of the furnace bridge, and when the discharge port needs to be exposed, the crossbar is pulled, and the furnace bridge is pulled by the crossbar to move horizontally to expose the discharge port.

[0014] Furthermore, a rectangular ash-pulling plate is slidably connected to the bottom end of the furnace core body, one end of the ash-pulling plate is fixedly connected to a lateral pull rod, one end of the pull rod away from the ash-pulling plate passes through the base and is located outside the base, the size of the ash-pulling plate is the same as the size of the furnace bridge, the ash-pulling plate is in sliding contact with the lower surface of the furnace bridge, and the sliding direction of the ash-pulling plate is opposite to the sliding direction of the furnace bridge. The purpose is that, firstly, when the ash-pulling plate overlaps with the furnace bridge, the ash-pulling plate closes the gap in the "E"-shaped furnace bridge, so that the smoke generated by the biomass particles during the combustion process can be effectively prevented from flowing into the base through the gap of the furnace bridge, and then discharged into the surrounding environment through the base, causing pollution to the surrounding air; secondly, the size of the shielding of the gap of the furnace bridge can be adjusted by moving the ash-pulling plate, thereby achieving the purpose of controlling the amount of oxygen entering the furnace core through the gap of the furnace bridge, so as to achieve the purpose of controlling the size of the firepower; and when the furnace bridge and the ash-pulling plate slide in two different directions at the same time, the discharge port can be exposed.

[0015] Furthermore, the sliding direction of the ash pulling plate is the direction of the gap of the furnace bridge, and two vertical ash pulling rods are fixedly connected to the upper surface of the ash pulling plate, and the two ash pulling rods pass through the two gaps of the furnace bridge respectively and extend to the top of the furnace bridge. The purpose is that through this arrangement, when the pull rod pulls the ash pulling plate back and forth, the ash pulling plate drives the two ash pulling rods to move back and forth in the gap of the furnace bridge, and the ash pulling rods squeeze and crush the fuel ash in the furnace core, so that part of the fuel ash can fall out of the furnace core through the gap of the furnace bridge.

[0016] Furthermore, the two ash pulling rods are close to the end of the ash pulling plate away from the pulling rod. The purpose is that through this arrangement, the ash pulling rods are close to the end away from the pulling rod, so that when the ash pulling rods move to the limit in the gap when the ash pulling plate is pulled, the ash pulling plate can effectively reduce the obstruction of the discharge port of the furnace core.

[0017] Furthermore, two limiting rings are fixedly connected to the bottom end of the furnace core, and two stabilizing shafts are fixedly connected to the end of the furnace bridge away from the crossbar. The two stabilizing shafts are respectively inserted into the two limiting rings and slidably connected to the limiting rings. The purpose is to limit the sliding direction of the furnace bridge so that it will not deviate during the sliding process through the sliding connection of the two limiting rings and the two stabilizing shafts, and to provide support for the furnace bridge through the limiting rings and the stabilizing shafts to prevent the furnace bridge from tilting downward due to the pressure of the fuel after long-term use.

[0024] The embodiment is basically as shown in the attached Figure 2 ~Attached Figure 4 As shown:

[0025] A furnace core of a biomass pellet stove, comprising a furnace core body 1, a base 2 and an ash removal mechanism; the furnace core body 1 can be selected from but not limited to a multifunctional furnace core with application number 202310840769.3, a smoke reduction furnace core of a return air furnace with application number 202321800751.2, or a furnace core for reducing temperature loss with application number 202321800727.9.

[0026] The furnace core body 1 is installed on the base 2. The bottom of the furnace core body 1 is provided with a discharge port, which is communicated with the inside of the base 2. The base 2 is provided with an ash box port 4.

[0027] The ash discharging mechanism includes an ash pulling plate 5 and an "E"-shaped furnace bridge 6, which is laterally slidably connected to the bottom end of the furnace core and is located directly below the discharge port. A crossbar 3 is welded to the closed end of the furnace bridge 6, and one end of the crossbar 3 away from the furnace bridge 6 passes through the base 2 and is located outside the base 2. Two limit rings 7 are welded to the bottom end of the furnace core body 1, and two stabilizing shafts 8 are welded to the open end of the furnace bridge 6. The ends of the two stabilizing shafts 8 away from the furnace bridge 6 are respectively inserted into the two limit rings 7 and slidably connected to the limit rings 7.

[0028] Two "L"-shaped limit plates 11 are fixedly connected to the bottom end of the furnace core body 1. The horizontal plate of the limit plate 11 is located directly below the furnace bridge 6 and the two horizontal plates are opposite to each other. The ash pulling plate 5 is slidably installed on the horizontal plate, and the upper surface of the ash pulling plate 5 is in sliding contact with the furnace bridge 6. A horizontal pull rod 9 is welded on the ash pulling plate 5. The end of the pull rod 9 away from the ash pulling plate 5 passes through the base 2 and is located outside the base 2, and the sliding direction of the ash pulling plate 5 is opposite to the sliding direction of the furnace bridge 6. Two vertical ash pulling rods 10 are fixedly connected to the upper surface of the ash pulling plate 5. The two ash pulling rods 10 are close to the end of the ash pulling plate 5 away from the pull rod 9. The two ash pulling rods 10 respectively pass through the two gaps of the furnace bridge 6 and extend to the top of the furnace bridge 6.

[0029] The specific implementation process is as follows:

[0030] Initially, the ash discharge mechanism is located directly below the discharge port to block the discharge port. After a large amount of biomass particles are piled up in the furnace core after ignition fails, the cross bar 3 and the pull rod 9 are pulled in opposite directions. The cross bar 3 pulls the furnace bridge 6 to move horizontally, and the pull rod 9 pulls the ash pulling plate 5 to move in the opposite direction of the furnace bridge 6. At this time, the furnace bridge 6 and the ash pulling plate 5 no longer block the discharge port. At this time, the biomass particles in the furnace core are discharged from the furnace core through the discharge port under the action of gravity and fall into the base 2, completing the discharge of the biomass particles in the furnace core when ignition fails. After the biomass pellet fuel in the furnace core is burned and used, the fuel ash generated by the biomass pellet fuel in the furnace core is fused into a mass due to the high temperature. The massed fuel ash cannot be discharged normally through the ash discharge because of its large volume. The cross bar 3 and the pull rod 9 are pulled in opposite directions. At this time, the furnace bridge 6 and the ash pulling plate 5 expose the discharge port. At this time, a tool is used to poke the massed fuel ash downward, and the fuel ash is broken into relatively small fuel ash. At this time, the volume of the fuel ash is reduced, and then it falls into the base 2 through the discharge port under the action of gravity. During the normal use of the furnace core, when the ash pulling plate 5 is pulled back and forth by the pull rod 9, the ash pulling plate 5 is used to drive the two ash pulling rods 10 to move back and forth in the gap of the furnace bridge 6, and the fuel ash of the furnace core is squeezed and crushed by the ash pulling rods 10, so that part of the fuel ash can fall out of the furnace core through the gap of the furnace bridge 6.
