Description

Technical Field

[0001] This utility model relates to the field of fuel burner technology, and in particular to biomass pellet fuel burners. Background Technology

[0002] Biomass pellet fuel burners, also known as biomass pellet burners, biomass gasification combustion furnaces, or biomass high-temperature pyrolysis burners, are devices that use biomass pellets as the main fuel to generate heat energy for industrial production and heating. They use biomass agricultural and forestry waste (straw, branches, bark, fruit shells, etc.) and wood processing scraps (wood chips, wood powder, sawdust, etc.) as fuel sources, and have significant advantages in energy utilization and environmental protection.

[0003] Patent document CN101793391B discloses a biomass pellet fuel burner, belonging to the field of renewable energy technology. The technical solution includes a slag-breaking and ash-removing mechanism and a combustion inner cylinder. The slag-breaking and ash-removing mechanism, connected to a motor via a movable interface, is installed in the combustion inner cylinder and consists of three parts: a fuel propulsion screw, a combustion agitation screw, and an ash discharge screw. Different air inlets are opened at three positions on the cylinder corresponding to the slag-breaking and ash-removing mechanism. This invention effectively solves the slag formation problem during pellet fuel combustion, realizing pellet conveying, stirring, slag breaking, and ash removal, thus improving combustion efficiency. It is suitable for different types of pellet fuels such as crop straw and forestry residues. This invention provides a guarantee for promoting the development of my country's biomass solid briquette fuel industry.

[0004] While the aforementioned application effectively solves the slagging problem during pellet fuel combustion, it is inconvenient to control the feed rate and flame size during actual application, thus reducing the ease of use of the burner. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] Reference Figures 1-5 A biomass pellet fuel burner includes a base 1, a combustion component 2 and a feed adjustment component 3 on the upper surface of the base 1, and a moving component 4 on the bottom of the base 1.

[0033] The combustion assembly 2 includes a cylinder 200 fixedly installed on a base 1. A positioning ring 201 is provided inside the cylinder 200. A support leg 202 is fixedly installed at the bottom of the positioning ring 201. A mesh plate 203 is fixedly installed inside the positioning ring 201. An ignition rod 204 is inserted into one side of the cylinder 200. A fan 205 is fixedly installed on one side of the upper surface of the base 1.

A cover 209 is threadedly connected to the top of the vertical pipe 208.

[0034] Specifically, the combustion component 2 allows for secondary air intake during use, ensuring more complete fuel combustion and preventing incomplete combustion that could produce smoke. It also facilitates internal cleaning. A mechanical valve 210 is connected to the bottom of the cylinder 200, extending through the base 1 and beyond it. This valve allows for easy cleaning of ash that has settled on the inner wall of the cylinder 200 after combustion. One side of the vertical pipe 208 connects to one side of the cylinder 200 via an air intake pipe 211, with a second one-way valve 212 connected to its surface. This second one-way valve 212 prevents gas from flowing back into the vertical pipe 208 from below the mesh plate 203 inside the cylinder 200 via the air intake pipe 211, allowing only the combusted gas to enter below the mesh plate 203 from inside the vertical pipe 208.

[0035] The feeding adjustment assembly 3 includes a positioning frame 300 fixedly installed on one side of the upper surface of the base 1. A box 301 is fixedly installed on the top of the positioning frame 300. A transmission pipe 302 is connected to one side of the box 301.

One side of the gate 305 penetrates the box 301 and extends to the outside of the box 301. A housing 306 is fixedly installed on one side of the housing 306. A sliding plate 307 is slidably connected inside the housing 306. A sliding rod 308 is fixedly installed on the top of the sliding plate 307. The top of the sliding rod 308 passes through the top of the housing 306 and extends to the outside of the housing 306. The top of the sliding rod 308 is fixedly connected to one side of the gate 305. A stepper motor 309 is fixedly installed on one side of the inner wall of the housing 306. A lead screw 310 is fixedly installed on the output shaft of the stepper motor 309. One end of the lead screw 310 passes through the sliding plate 307 and extends to the outside of the sliding plate 307.

[0036] Specifically, the feed adjustment component 3 can control the fuel output according to the combustion situation during use, thereby controlling the flame size and improving the ease of use of the burner. The transmission pipe 302 is set in an inclined state, and the side of the transmission pipe 302 near the vertical pipe 208 is connected to the first one-way valve 311. The transmission pipe 302 facilitates fuel transmission during use, and the first one-way valve 311 is set to allow fuel to be fed only from the transmission pipe 302 into the cylinder 200. The upper surface of the housing 306 has rod grooves on both sides for the slide rod 308 to pass through, and the inner wall of the rod groove is slidably connected to the surface of the slide rod 308. One side of the box 301 is opened A groove is provided for the gate plate 305 to pass through, and the inner wall of the groove is slidably connected to the surface of the gate plate 305. A rod groove is provided to facilitate the limiting of the sliding rod 308 during use, and also to facilitate the movement of the sliding rod 308 inside the rod groove. The groove is designed to facilitate the passage of the gate plate 305. A threaded hole is provided on the slide plate 307 for the lead screw 310 to pass through, and the threaded hole is threadedly connected to the lead screw 310. A sleeve is fitted on one end of the lead screw 310 and rotatably connected to one end of the lead screw 310. One end of the sleeve is fixedly connected to one side of the inner wall of the housing 306. The sleeve is provided to facilitate the limiting of one end of the lead screw 310 during use, and to prevent the one end of the lead screw 310 from shaking during the rotation of the lead screw 310.

[0037] Reference Figure 1 In a preferred embodiment, the moving component 4 includes support rods 400 fixedly installed at the four corners of the bottom of the base 1. The bottom of the support rods 400 is rotatably connected to a bracket 401 via a bearing. The inside of the bracket 401 is rotatably connected to a roller 402 via a rotating shaft. The bracket 401 and the roller 402 are provided to facilitate the support of the burner during use and also facilitate the movement of the burner.

[0038] Working principle: The burner is placed in the designated location. When heat is needed for the drying equipment, the burner pipe 207 is connected to the air inlet of the drying equipment. Fuel is then added into the hopper 303. The stepper motor 309 is controlled to operate, and its rotation drives the slide plate 307 on the lead screw 310 to move. This causes one side of the gate plate 305 on the slide rod 308 to separate from one side of the inner wall of the box 301, allowing fuel to enter the box 301. When the feed rate needs to be controlled, the stepper motor 309 drives the slide rod 308 on the slide plate 307 to move, thereby adjusting the size of the gate plate 305 on the slide rod 308 relative to the inner wall of the box 301. The fuel is then transferred through the transmission pipe 302 into the interior of the vertical pipe 208 and falls above the mesh plate 203. The ignition rod 204 is controlled to ignite the fuel on the mesh plate 203, while the fan 205 is controlled to operate. The fan 205 delivers air into the interior of the cylinder 200 through the air inlet pipe 211, accelerating the combustion of the fuel inside the cylinder 200. The incompletely combusted gas will enter the area below the mesh plate 203 through the air inlet pipe 211 and undergo secondary combustion when passing over the flame on the mesh plate 203. When it is necessary to clean the ash inside the cylinder 200, the mechanical valve 210 is opened and the cover 209 is loosened to remove the ash from the mechanical valve 210.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
