[0014] Preferably, observation windows are also provided on the side walls of the second combustion chamber.

[0015] Compared with the prior art, this utility model has the following advantages and effects:

[0016] This utility model relates to a wood chip burner. Compared to traditional burner structures, this wood chip burner features a material guiding channel formed by multiple sets of guide plates and guide screens located below the feed inlet inside the combustion chamber. This channel effectively confines the space for wood chips and other biomass raw materials during combustion. Simultaneously, the arrangement of the blower through the first exhaust channels and their first exhaust vents on both sides of the combustion chamber, and the second exhaust channel and its multiple sets of second exhaust vents located above the material guiding channel, along with the way the blower disperses the wood chips and other biomass raw materials within the material guiding channel, reduces the likelihood of material blockage. Furthermore, the combustion process of the coal and other fuels below the guide screens and above the second guide screens located in the storage chamber, along with the structure of the guide screens with corresponding aperture sizes according to combustion requirements, ensures that the wood chips and other biomass raw materials within the material guiding channel, once they reach the combustion standard, can be discharged through the outlet via the guide screens at the corresponding positions within the material guiding channel. This further improves the stability, completeness, and uniformity of the combustion of the wood chips and other biomass raw materials within the material guiding channel. This design effectively improves the combustion rate and completeness of coal and other fuels above the second guide screen plate in the storage chamber, enhancing the combustion effect and working efficiency of this wood chip burner. The second guide screen plate is detachably connected within the storage chamber via a sliding rail inside the combustion chamber and a first baffle on its side, facilitating the addition of coal and other fuels. A baffle plate sliding on the feed inlet within a groove at the top of the combustion chamber allows for easy adjustment of the opening size according to feeding requirements. The complete closure of the feed inlet by the baffle further improves the combustion effect of wood chips and other biomass raw materials in the guide channel. An ash outlet at the bottom of the combustion chamber facilitates timely discharge and cleaning of waste residue and ash generated during combustion, meeting various usage needs. Furthermore, the feed inlet and outlet of the combustion chamber can be connected to a conveying device for wood chips and other biomass raw materials, as well as subsequent processing equipment such as secondary combustion or drying equipment, depending on usage requirements. This design, combined with the above, allows for convenient addition of fuels and other fuels. Figure 3 The detachable design of the combustion chamber structure further enhances the flexibility, ease of maintenance, applicability, and practicality of this wood chip burner. Combined with the overall structural design of this wood chip burner, it also offers certain operational convenience and energy-saving and environmental benefits. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in detail with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0027] See Figure 1-6This embodiment relates to a wood chip burner, including a frame 1, a combustion chamber 1 mounted on the frame, and a fan 2 connected to the combustion chamber 1. The top of the combustion chamber 1 has a feed inlet 11, and a baffle 111 is slidably mounted on the feed inlet 11. Inside the combustion chamber 1, below the feed inlet 11, a guide channel 12 is formed by multiple sets of guide plates 121 and guide screen plates 122. A discharge outlet 13 is opened on the side of the combustion chamber 1 along the discharge direction of the guide channel 12. The fan 2 exhausts air through first exhaust fans located on both sides of the combustion chamber 1. The channel 14 and the first exhaust port 141 provided thereon are connected to the second exhaust channel 15 provided above the material guide channel 12. The second exhaust channel 15 has multiple sets of second exhaust ports 151 arranged along the discharge direction of the discharge port 13. The combustion chamber 1 located below the material guide channel 12 is provided with a material storage chamber 16 and a second material guide screen plate 161 is slidably provided inside the material storage chamber 16. An ash outlet 17 is provided at the bottom of the combustion chamber 1 located below the material guide screen plate 122 and the second material guide screen plate 161 in the material guide channel 12.

[0028] Specifically in this embodiment, such as Figure 1 The overall structure of this type of wood chip burner shown can be combined with... Figure 2-6 As shown, the second guide screen plate 161 is slidably disposed in the storage chamber 16 via a slide rail 160 provided inside the combustion chamber 1 and a first baffle 1223 covering its side. This allows for the feeding and ignition of coal and other combustion agents above the second guide screen plate 161 within the storage chamber 16. Furthermore, biomass raw materials such as wood chips can be fed into the combustion chamber 1 through the feed inlet 11. The wood chips and other biomass raw materials entering the combustion chamber 1 through the feed inlet 11 can accumulate in the guide channel 12. Specifically, from... Figure 2-6As can be seen, the arrangement of multiple sets of guide plates 121 and guide screen plates 122 in the material guide channel 12 allows biomass raw materials such as wood chips to slide down along the guide plates 121 onto the guide screen plates 122 located below the second exhaust port 151 on the second exhaust channel 15. Furthermore, the guide screen plates 122 and 161 can be configured according to the specific specifications and corresponding particle sizes of the biomass raw materials such as wood chips and the combustion agent such as coal, ensuring that no material falls off during the early stages of combustion. This process is carried out when the biomass raw materials such as wood chips enter the combustion chamber 1. Simultaneously with the feeding at the inlet 11, the blower 2, located at the bottom of the combustion chamber 1 and mounted on the frame 1, operates. Air is then exhausted through the first exhaust channels 14 and their first exhaust ports 141 on both sides of the combustion chamber 1 into the second exhaust channel 15 above the guide channel 12. Simultaneously, air is discharged through multiple sets of second exhaust ports 151 on the second exhaust channel 15, thus dispersing the wood chips and other biomass raw materials within the guide channel 12. Simultaneously, the dispersed material is discharged from the storage chamber 16 below the guide screen plate 122 within the guide channel 12. The coal and other fuel ignited on the feed sieve plate 161 burns through the feed guide sieve plate 122. Once the biomass raw materials, such as wood chips, have burned completely and reached the size of the sieve holes on the feed guide sieve plate 122, the blower 2, through the second exhaust port 151, continuously blows the fuel through the feed guide sieve plate 122 positioned at the corresponding location in the feed guide channel 12 and discharges it through the outlet 13. Specifically, the feed guide sieve plate 122, positioned along the discharge direction of the outlet 13 on the feed guide channel 12, can have its sieve holes sized according to the combustion requirements of the biomass fuel, such as wood chips. In the initial setup process, the blower 2, through the second exhaust port 151, continuously disperses the biomass raw materials such as wood chips that do not meet the combustion standard within the feed channel 12. Combined with the continuous combustion of the combustion agent, the biomass raw materials such as wood chips that meet the combustion standard can be discharged through the feed screen 122 and the discharge port 13. During the combustion process, the waste residue produced by the biomass raw materials such as wood chips and the combustion agent such as coal can be discharged through the feed screen 122 and the second feed screen 161 to the ash outlet 17 opened at the corresponding position at the bottom of the combustion chamber 1 for subsequent discharge.Compared to traditional burner structures, this type of wood chip burner features a material guiding channel 12 formed by multiple sets of guide plates 121 and guide screen plates 122 located below the feed inlet 11 inside the combustion chamber 1. This channel effectively confines the space for biomass raw materials such as wood chips during combustion. Furthermore, the arrangement of the blower 2 through the first exhaust channels 14 on both sides of the combustion chamber 1 and the first exhaust ports 141 thereon, and the second exhaust channel 15 above the material guiding channel 12 and its multiple sets of second exhaust ports 151, along with the way the blower disperses the biomass raw materials within the material guiding channel 12, reduces the likelihood of… Simultaneously with material blockage, the combustion process of coal and other fuels located below the guide screen 122 and above the second guide screen 161 within the storage chamber 16, along with the structure of the guide screen 122 with corresponding aperture sizes according to combustion requirements, ensures that biomass raw materials such as wood chips in the guide channel 12, after reaching the combustion standard, can be discharged through the outlet 13 via the guide screen 122 at the corresponding position in the guide channel 12. This further improves the stability, completeness, and uniformity of combustion of biomass raw materials such as wood chips in the guide channel 12, and also effectively improves the storage capacity. The combustion rate and completeness of the coal and other fuels above the second guide screen plate 161 in the material chamber 16 improve the combustion effect and working efficiency of this wood chip burner. Furthermore, the second guide screen plate 161 is detachably connected to the storage chamber 16 via a slide rail 160 inside the combustion chamber 1 and a first baffle 1223 on its side, facilitating the addition of coal and other fuels. The baffle 111, slidably mounted on the feed inlet 11 within the chute 110 at the top of the combustion chamber 1, also allows for adjustments to the opening size according to feeding requirements. Small adjustments, combined with the operation of completely sealing the feed inlet 11 by the baffle 111, can further improve the combustion effect of biomass raw materials such as wood chips in the feed channel 12. The ash outlet 17 opened at the corresponding position at the bottom of the combustion chamber 1 also facilitates the timely discharge and cleaning of waste residue and furnace ash generated during the combustion process, meeting different usage needs. In addition, the feed inlet 11 and the discharge outlet 13 on the combustion chamber 1 can be connected to the conveying device of biomass raw materials such as wood chips and subsequent processing equipment such as secondary combustion or drying, respectively, according to usage needs, and in combination with 2 and . Figure 3 The detachable overall structure of the combustion chamber 1 shown further improves the flexibility, ease of maintenance, applicability, and practicality of this wood chip burner. Combined with the overall structural design of this wood chip burner, it also offers certain operational convenience and energy-saving and environmental protection benefits.

[0029] The material guiding screen plate 122 includes a first plate 1221 with a plurality of screen holes and respectively located above the second material guiding screen plate 161, and a second plate 1222 located above the first plate 1221, mounted on the material guiding plate 121 and inclined at a certain angle along the discharge port 13. The material guiding channel 12 is slidably disposed in the combustion chamber 1, and multiple sets of material guiding plates 121 and material guiding screen plates 122 thereon are connected by a detachable structure. A locking member 18 is rotatably disposed on the side of the combustion chamber 1 located in the sliding direction of the material guiding channel 12. The feed sieve plate 122, which is arranged in this manner on the feed channel 12, allows biomass raw materials such as wood chips to accumulate on the first plate 1221 when entering the feed channel 12 through the feed inlet 11 at the top of the combustion chamber 1 and multiple sets of feed sieve plates 121. Simultaneously, as the blower 2 disperses the biomass raw materials on the first plate 1221 through the second exhaust port 151 along the discharge port 13, the second plate 1222, which is inclined at a certain angle on the first plate 1221, allows the biomass raw materials such as wood chips that have not met the combustion standard to move downwards along the second plate 1222 onto the first plate 1221. This effectively reduces the phenomenon of unburned blocky biomass raw materials remaining on the second plate 1222, causing sieve blockage, thus improving the discharge effect and discharge stability. Furthermore, combined with the storage material below the first plate 1221... The continuous combustion process of the propellant above the second guide screen plate 161 in the cavity 16 can further improve the combustion effect and stability of biomass raw materials such as wood chips in the guide channel 12. In addition, the first plate 1221 and the second plate 1222 of the multiple sets of guide plates 121 and guide screen plates 122 are detachably connected by bolts. At the same time, the formed guide channel 12 is detachably installed in the combustion chamber 1 through the second baffle 162 set on the side of the burner and slidably installed in the cavity of the combustion chamber 1. Combined with the locking member 18 rotatably set on one side of the combustion chamber 1, the guide channel 12 is locked in position and slidable around the second baffle 162 on the guide channel 12. This facilitates the observation, cleaning and structural disassembly of the guide channel 12, improving the combustion stability of the combustion chamber 1 and the overall detachability, disassembly flexibility and working efficiency of this wood chip burner.

[0030] A gap is left between the second plate 1222 and the second exhaust duct 15, and a roller 19 is rotatably installed in the combustion chamber 1 at the corresponding gap, from... Figure 3 or Figure 4As can be seen, the roller 19 is designed and added in a corresponding size to ensure that biomass raw materials such as wood chips that do not meet the combustion standard will not be discharged through the gaps formed by the second exhaust channel 15 and the second plate 1222 on the upper and lower sides of the roller 19, respectively. Thus, the addition of the roller 19 structure can further improve the material guiding effect of the material guiding channel 12, and at the same time, it can further improve the ventilation effect inside the combustion chamber 1 and the operation speed of the sliding adjustment process of the material guiding channel 12 in the combustion chamber 1 cavity.

[0031] The multiple sets of second exhaust vents 151 on the second exhaust duct 15 are set at the same tilt angle as the second plate 1222, and filter plates 152 can be detachably installed on each of the second exhaust vents 151. Specifically, from Figure 4 As can be seen, the multiple sets of second exhaust ports 151 set at the same inclination angle as the second plate 1222 on the second exhaust channel 15 can further improve the guiding effect of biomass raw materials such as wood chips in the guiding channel 12, reduce the phenomenon of blockage, and improve the stability of the discharge of biomass raw materials such as wood chips. In addition, the filter plate 152 installed by the detachable connection method of being locked in the slot 1511 set on the second exhaust port 151 can also effectively prevent biomass raw materials such as wood chips from entering the second exhaust channel 15 through the second exhaust port 151, thereby improving the exhaust stability and effect of the fan 2.

[0032] A second baffle 112 is slidably disposed on the top of the combustion chamber 1 located between the material guide channel 12 and the feed inlet 11 to block the material guide channel 12. Figure 3 and Figure 4 As can be seen, the addition of the second baffle 112 structure can adjust or close the material guide channel 12 located below the second exhaust channel 15 according to the usage requirements through the sliding process of the second slide groove 110 provided at the top of the combustion chamber 1. Combined with the adjustment of the baffle 111 on the feed inlet 11, it can further improve the stability and uniformity of biomass raw materials such as wood chips entering the material guide channel 12, and improve the flexibility of use.

[0033] See Figure 7 The combustion chamber 1 located below the ash outlet 17 is also slidably equipped with an ash storage box 3. The ash storage box 3 is slidably equipped on the combustion chamber 1 through a detachable connection between its outer edge 31 on the top and a second slide rail 171 located below the ash outlet 17 on the top of the combustion chamber 1. This facilitates the unified collection and subsequent cleaning of the waste residue and furnace ash discharged from the ash outlet 17 during the combustion process, improving the flexibility of use and the convenience of operation.

[0034] like Figure 1As shown, a feed hopper 4 is also installed on the feed inlet 11. The feed hopper 4 can be installed on the feed inlet 11 at the top of the combustion chamber 1 according to the usage requirements, so as to improve the stability and efficiency of feeding biomass raw materials such as wood chips and meet different usage requirements.

[0035] The bottom of the frame 1 is also equipped with a wheel set 101. The addition of the wheel set 101 can facilitate the adjustment of the frame 1 and the combustion chamber 1 on it to different positions. It can also facilitate the connection of the discharge port 13 on the combustion chamber 1 with subsequent discharge equipment such as secondary combustion or drying, in combination with different usage requirements, thereby improving the flexibility and applicability of use.

[0036] It also includes a second frame 5 and a second combustion chamber 6 connected to the combustion chamber 1. The second combustion chamber 6 has a second inlet 61 connected to the outlet 13 and a second outlet 62 with a rotating door assembly 621 at both ends. A second storage chamber 631 formed by a third guide screen 63 is provided inside the second combustion chamber 6. Third exhaust channels 64, connected by multiple sets of first exhaust pipes 65, are provided at the upper and lower ends of the second combustion chamber 6. The third exhaust channel 64 located above the second combustion chamber 6 is connected to the internal cavity of the second combustion chamber 6 through several third exhaust ports 641. The third exhaust channel 64 located below the second combustion chamber 6 is connected to a second exhaust pipe 66 installed at the bottom of the second combustion chamber 6. Figure 1 The wood chip burner shown can also be equipped with a second frame 5 and a second combustion chamber 6 connected to the discharge port 13 of the combustion chamber 1 via a second feed inlet 61, depending on usage requirements and combustion needs. See [link to documentation] for details. Figure 8 and Figure 9As shown, after combustion in combustion chamber 1, the powdery wood chips and other biomass raw materials discharged through discharge port 13 can enter the cavity of the second combustion chamber 6 through the second feed port 61. During use, the second combustion chamber 6, combined with the second discharge port 62 on which a door assembly 621 is rotatably installed, adds and ignites coal and other combustion agents into the second storage cavity 631 formed by the third guide screen plate 63. This allows the powdery wood chips and other biomass raw materials in the cavity of the second combustion chamber 6 to undergo a secondary combustion process. Simultaneously, the gas generated during the secondary combustion process enters the third exhaust channel 64 at the top of the cavity of the second combustion chamber 6 through the third exhaust port 641, and then passes through multiple sets of first... The exhaust pipe 65 enters the third exhaust channel 64 formed between the bottom of the second combustion chamber 6 and the second frame 5, and then is discharged through the second exhaust pipe 66 installed on the second frame 5. In combination with the secondary combustion process of the second combustion chamber 6 on the second frame 5, the wood chips and other biomass raw materials located above the third guide screen plate 63 in the second combustion chamber 6 can be conveniently discharged through the second discharge port 62 and the rotating door group 621 on it. At the same time, this can further improve the functional versatility and combustion effect of this wood chip burner, improve the combustion stability and combustion completeness of wood chips and other biomass raw materials, and improve the flexibility of use, ease of operation and applicability.

[0037] The second combustion chamber 6 is also provided with observation windows 67 on both side walls. The addition of the observation windows 67 can facilitate real-time observation of the combustion situation in the second combustion chamber 6, and facilitate timely adjustment of any abnormalities that occur during the combustion process, thereby improving the combustion stability of the second combustion chamber 6.

[0038] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
