[0002] Biomass fuel is a renewable energy source with advantages such as being environmentally friendly, renewable, and low-carbon. In recent years, it has been widely used in the energy sector. In the process of biomass fuel production, it is necessary to first collect various biomass raw materials, such as crop straw, forestry waste, and specific energy crops. These raw materials undergo pretreatment, such as cutting and grinding, to adapt to the subsequent conversion process. The converted biomass raw materials are then processed into pellets according to the usage requirements using a pelletizing device.

[0003] In existing pelleting equipment, during the feeding process, the pelleted biomass pellets tend to accumulate inside the receiving bin. The existing pelleting equipment cannot smoothly discharge the accumulated biomass pellets inside the receiving bin, causing blockage and affecting the discharge efficiency of the pelleting equipment.

The bottom end of the granulation mesh bin is fixedly installed inside the receiving bin. One side of the drive motor is fixedly installed on the inner side of the support frame via a mounting plate. The output end of the drive motor is fixedly connected to a first rotating rod via a shaft. A first rotating wheel is fixedly fitted onto the surface of the first rotating rod near the drive motor.

[0008] As a further preferred embodiment of this technical solution, the top end of the first rotating rod extends through the interior of the receiving chamber and into the interior of the granulation mesh chamber.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, a pelletizing device for biomass fuel production includes a receiving bin 1. A support frame 101 is fixedly installed at the bottom of the receiving bin 1, and a feed inlet 102 is connected to the top of the support frame 101. A discharge outlet 103 is connected to one side of the outer wall of the receiving bin 1, allowing the pelletized biomass fuel inside the receiving bin 1 to be discharged through the discharge outlet 103. The receiving bin 1 is equipped with a pelletizing mechanism 2 for forming biomass fuel into pellets. The pelletizing mechanism 2 includes a pelletizing mesh bin 201 and a drive motor 202. The bottom end of bin 201 is fixedly installed inside the bottom end of receiving bin 1. One side of drive motor 202 is fixedly installed inside support frame 101 via mounting plate. The output end of drive motor 202 is fixedly connected to a first rotating rod 203 via a shaft. A first rotating wheel 204 is fixedly fitted onto the surface of the first rotating rod 203 near the drive motor 202. The top end of the first rotating rod 203 extends through the interior of receiving bin 1 into the interior of granulation mesh bin 201. A mounting bracket 205 is fixedly fitted onto the end of the first rotating rod 203 near the interior of granulation mesh bin 201. Extrusion rollers 206 are equidistantly mounted at the bottom of the mounting frame 205. The surfaces of several sets of extrusion rollers 206 are in contact with the inner wall of the pelleting mesh bin 201. An installation sleeve 207 is fixedly fitted onto the top of the outer wall of the pelleting mesh bin 201. The installation sleeve 207 has a guide groove 208 inside. First, the top of the feed inlet 102 is connected to the discharge pipe of the biomass fuel raw material conveying equipment, so that the raw material in the conveying equipment can enter the interior of the pelleting mesh bin 201 from the feed inlet 102. When the raw material has completely entered the interior of the pelleting mesh bin 201, it is activated by starting... The drive motor 202 drives the first rotating rod 203 to rotate. The rotating first rotating rod 203 drives several sets of extrusion rollers 206 to rotate inside the pelletizing mesh bin 201 through the mounting frame 205. During the rotation, the extrusion rollers 206 squeeze the raw material inside the pelletizing mesh bin 201 and stick it to the inner wall of the pelletizing mesh bin 201. Through the force of the several sets of continuously rotating extrusion rollers 206, the raw material is squeezed out from the mesh of the pelletizing mesh bin 201 to form pellet biomass fuel, thus realizing the function of pelletizing biomass fuel.

[0021] like Figure 1 and Figure 2 as well as Figure 4As shown, a feeding mechanism 3 for cleaning up the accumulated particles inside the receiving bin 1 is provided on the outer side near the granulation mechanism 2. The feeding mechanism 3 includes a guide ring 301, one end of which is snapped into the inside of the guide groove 208. A first gear 302 is fixedly mounted on the surface of the guide ring 301. Scrapers 303 are equidistantly mounted on the bottom end of the first gear 302. One side of several sets of scrapers 303 is in contact with the outer wall of the granulation mesh bin 201. A second gear 304 is meshed with the surface of the first gear 302. A second rotating rod 305 is fixedly inserted into the inside of the second gear 304. A second rotating wheel 306 is fixedly mounted on the surface of the second rotating rod 305 away from the second gear 304. A belt 307 is wrapped around the surface of the second rotating wheel 306. The end of the belt 307 away from the second rotating wheel 306 is wrapped around the surface of the first rotating wheel 204. The first rotating rod 203 drives several... As the extrusion roller 206 rotates, the first rotating wheel 204 mounted on the first rotating rod 203 also rotates. The rotating first rotating wheel 204 drives the second rotating wheel 306 to rotate via the belt 307. The rotating second rotating wheel 306 drives the second gear 304 to rotate via the second rotating rod 305. The rotating second gear 304 drives the first gear 302 to rotate. The rotating first gear 302 rotates at the top of the pelletizing mesh bin 201 via the rotation of the guide ring 301 inside the guide groove 208. The rotating first gear 302 drives several sets of scrapers 303 to rotate on the outer wall of the pelletizing mesh bin 201. The rotating scrapers 303 scrape the extruded pellets from the mesh of the pelletizing mesh bin 201. The scraped-off pellets of biomass fuel fall along the outer wall of the pelletizing mesh bin 201 into the receiving bin 1, thus completing the pelletizing process of biomass fuel.

[0022] This utility model provides a pelletizing device for biomass fuel production. The specific working principle is as follows: When using this pelletizing device, the top of the feed inlet 102 is first connected to the discharge pipe of the biomass fuel raw material conveying equipment, so that the raw material in the conveying equipment can enter the interior of the pelletizing mesh bin 201 from the feed inlet 102. When the raw material has completely entered the interior of the pelletizing mesh bin 201, the drive motor 202 is started to drive the first rotating rod 203 to rotate. The rotating first rotating rod 203 drives several sets of extrusion rollers 206 to rotate inside the pelletizing mesh bin 201 through the mounting frame 205. During the rotation, the several sets of extrusion rollers 206 will squeeze the raw material inside the pelletizing mesh bin 201 to adhere to the inner wall of the pelletizing mesh bin 201. Through the force of the several sets of continuously rotating extrusion rollers 206, the raw material is squeezed out from the mesh of the pelletizing mesh bin 201 to form granular biomass fuel, thus performing the function of pelletizing biomass fuel.

[0023] While the first rotating rod 203 drives several sets of extrusion rollers 206 to rotate, the first rotating wheel 204 mounted on the first rotating rod 203 rotates accordingly. The rotating first rotating wheel 204 drives the second rotating wheel 306 to rotate via the belt 307. The rotating second rotating wheel 306 drives the second gear 304 to rotate via the second rotating rod 305. The rotating second gear 304 drives the first gear 302 to rotate. The rotating first gear 302 rotates at the top of the pelletizing mesh bin 201 by rotating the guide ring 301 inside the guide groove 208. The rotating first gear 302 drives several sets of scrapers 303 to rotate on the outer wall of the pelletizing mesh bin 201. The rotating scrapers 303 scrape the extruded pellets on the mesh of the pelletizing mesh bin 201 off. The scraped-off pellet biomass fuel falls along the outer wall of the pelletizing mesh bin 201 into the interior of the receiving bin 1, thus completing the pelletizing process of biomass fuel.

[0024] While scraping off the pellets extruded and formed on the mesh of the pelletizing bin 201, several sets of scrapers 303 rotate and push the pellet biomass fuel falling into the receiving bin 1 to rotate, so that the pellet biomass fuel inside the receiving bin 1 is in a flowing state. When the flowing pellet biomass fuel passes through the discharge port 103, it is discharged from the discharge port 103 by its own gravity, which facilitates the smooth discharge of the pellet biomass fuel accumulated inside the receiving bin 1.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
