Description

Technical Field

[0001] This application relates to the technical field of biomass pellet fireplaces, and in particular to a biomass pellet fireplace ash removal device. Background Technology

[0002] Biomass pellet fireplaces are widely used due to their environmentally friendly fuel and high thermal efficiency. The secret to the heating effect of biomass pellet fireplaces lies in their internal combustion process. First, biomass pellets are put into the furnace and then ignited. During the combustion process, the hydrocarbons in the pellets react with oxygen to release heat energy and carbon dioxide. The heat energy is conducted through the furnace wall to warm the surrounding air, while the carbon dioxide produced by combustion is discharged outdoors, reducing indoor air pollution.

[0003] In existing biomass pellet fireplaces, ash produced during the combustion of biomass pellets tends to accumulate on the surface of the biomass pellets and in the gaps of the grate, leading to obstructed ventilation, reduced combustion efficiency, and incomplete combustion of fuel due to the accumulation of ash hindering airflow.

[0004] Therefore, those skilled in the art have provided a biomass pellet fireplace ash removal device to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a biomass pellet fireplace ash removal device.

[0006] The biomass pellet fireplace ash removal device provided in this application adopts the following technical solution:

[0007] A biomass pellet fireplace ash removal device includes a housing, a grate assembly installed inside the housing, and an ash removal assembly installed inside the grate assembly. The ash removal assembly includes two annular mounting plates, and a plurality of annularly arranged equidistant flipping plates are fixedly connected between the two annular mounting plates. A discharge hood is fixedly connected to the rear end of the rear annular mounting plate, and a connecting rod is fixedly connected to the inner side of the discharge hood. The rear end of the connecting rod is fixedly connected to the screw rod of the screw conveying mechanism in the biomass pellet fireplace.

[0008] Preferably, the grate assembly includes several semi-circularly arranged crossbars, and several arc-shaped rods are welded to the inner side of the crossbars.

[0009] Preferably, the feeding hood is a hollow frustum-shaped design.

[0010] Preferably, three reinforcing rings are fixedly connected to the outer side of several of the flipping plates, the three reinforcing rings are arranged at equal intervals, and steel wire brush bristles are fixedly connected to one of the flipping plates.

[0011] Preferably, a baffle is installed on the inner side of the housing near the front end.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. The screw conveyor mechanism's screw drives the connecting rod, annular mounting plate, tilting plate, reinforcing ring, and discharge hood to rotate. The tilting plate continuously agitates the fuel as it rotates, cleaning the ash and slag from the fuel surface. The tilting plate works in conjunction with the wire brush to achieve dynamic fuel agitation and simultaneous cleaning of ash and slag on the grate surface, preventing poor ventilation caused by ash and slag accumulation. The semi-circular grate assembly increases the air contact area at the bottom of the fuel, improving combustion efficiency and reducing unburned carbon residue. The reinforcing ring and arc-shaped rod enhance the rigidity of the tilting plate and crossbar, preventing high-temperature deformation. This mechanism effectively cleans ash and slag from the surface of biomass pellet fuel and from ash and slag in the grate gaps, preventing ash and slag accumulation from obstructing airflow and causing incomplete fuel combustion.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1 ,4 As shown in Figure 5, this application discloses a biomass pellet fireplace ash removal device, including a housing 1, a grate assembly installed on the inner side of the housing 1, an ash removal assembly installed on the inner side of the grate assembly, the ash removal assembly including two annular mounting plates 5, a plurality of annularly arranged flipping plates 6 installed between the two annular mounting plates 5, a discharge hood 8 installed at the rear end of the annular mounting plate 5, a connecting rod 9 installed on the inner side of the discharge hood 8, and the rear end of the connecting rod 9 being fixedly connected to the screw rod of the screw conveying mechanism in the biomass pellet fireplace.

[0024] When the screw of the screw conveyor rotates, the biomass pellet fuel is fed along the inner wall of the feeding hood 8. The connecting rod 9 drives the annular mounting plate 5, the flipping plate 6, the reinforcing ring 7 and the feeding hood 8 to rotate. When the flipping plate 6 rotates, it flips the accumulated biomass pellet fuel and performs ash removal.

[0025] like Figure 3 , 5 As shown, the grate assembly includes several semi-circularly arranged crossbars 3, and several arc-shaped rods 4 are welded to the inner side of the crossbars 3. By arranging the crossbars 3 in a semi-circular shape, the contact area between the bottom of the biomass pellet fuel and the air can be increased. The crossbars 3 can be reinforced by setting the arc-shaped rods 4.

[0026] like Figure 1 , 4 As shown in Figure 5, the feeding hood 8 is a hollow frustum-shaped design. By setting the feeding hood 8 with a hollow frustum-shaped design, it is convenient to feed biomass pellet fuel.

[0027] like Figure 1 , 4 As shown in Figures 5 and 6, three reinforcing rings 7 are installed on the outer side of several flipping plates 6. The three reinforcing rings 7 are arranged at equal intervals. A steel wire brush 10 is installed on one of the flipping plates 6. The flipping plate 6 can be reinforced by setting the reinforcing rings 7. The grate assembly can be cleaned by setting the steel wire brush 10 on the flipping plate 6.

[0028] like Figure 1 , 2 As shown, a baffle 2 is installed on the inner side of the housing 1 near the front end. By setting the baffle 2, it is convenient to maintain the dust removal component after disassembly.

[0029] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0030] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0031] The implementation principle of a biomass pellet fireplace ash removal device according to an embodiment of this application is as follows:

[0032] During operation, as the screw of the screw conveyor rotates, biomass pellet fuel falls evenly into the furnace along the inner wall of the hollow frustum-shaped discharge hood 8. The frustum-shaped design 8 guides fuel distribution through a gradually narrowing cross-section, preventing local accumulation. One end of the connecting rod 9 is fixed to the screw, and the other end is connected to the annular mounting plate 5 located at the rear, synchronously transmitting the rotational power of the screw to the ash removal assembly, causing the annular mounting plate 5, the flipping plate 6, the reinforcing ring 7, and the discharge hood 8 to rotate as a whole. The annularly spaced flipping plates 6 continuously agitate the fuel as they rotate. The material is broken up by ash and slag clumping and promotes fuel tumbling, enhancing contact with air. A steel wire brush 10 mounted on the outer side of one of the turning plates 6 scrapes against the crossbars 3 and arc-shaped bars 4 of the grate assembly during rotation, removing attached ash and slag and preventing blockage. Three equidistant reinforcing rings 7 provide multi-point reinforcement to the turning plate 6, ensuring its structural stability under high-temperature conditions. The grate assembly consists of semi-circularly arranged crossbars 3 and welded arc-shaped bars 4, forming a porous arc-shaped support surface, increasing the bottom ventilation area of ​​the fuel and promoting uniform combustion. The arc-shaped bars 4 also enhance the rigidity of the crossbars 3, preventing deformation. The removable baffle 2 at the front end of the shell 1 can be removed for maintenance, allowing direct maintenance of the ash removal assembly and shortening downtime.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
