The present invention provides a straw bale drying device for biomass power generation, which has the following beneficial effects:

1. The straw bale drying device for biomass power generation places the straw bale in the middle of the fixed ring when in use, and the external air supply device is connected to the lower side of the connecting hole.

2. The straw bale drying device for biomass power generation drives the fan blades to rotate the rotating rod while the airflow is discharged through the slide cylinder, and the rotating rod drives the threaded plate to rotate the wire. Due to the presence of two magnets, an electric potential is generated while the wire rotates, so that the current passes through the wire to heat the resistance heating block, thereby heating the airflow and the outer wall of the slide cylinder, thereby accelerating the drying speed of the straw bale.

3. In the straw bale drying device for biomass power generation, when the slide drum is venting air, if there is a lot of water vapor inside the straw bale, making it difficult for the slide drum to vent air, the rotation speed of the fan blade will decrease, causing the first spring to pull the surface of the threaded plate to clamp the threaded ring. Since the threaded plate is threadedly connected to the outer wall of the threaded ring, the threaded ring will drive the sealing plate to rise, causing the sealing plate to block the exhaust port at the rear side, thereby reducing the number of exhaust ports, increasing the wind pressure at other exhaust ports, and allowing the airflow to quickly penetrate the straw bale for rapid drying.

4. In the straw bale drying device for biomass power generation, after reducing the exhaust from the exhaust holes on the rear side to increase the wind pressure, if the airflow penetration efficiency is still insufficient and the airflow cannot be discharged, the internal pressure of the slide cylinder will increase, causing the magnet to move toward the inside of the magnet slot, so that the gas inside the magnet slot squeezes the sealing sheet, causing the sealing sheet to rise and block the exhaust port on the side, leaving only the exhaust port on the front side, and concentrating the wind pressure to penetrate and blow the straw bale, so that it can be quickly dried bit by bit, thereby achieving the purpose of accelerating deep drying.

After reducing the exhaust of the exhaust holes on the rear side and increasing the wind pressure, when the airflow penetration efficiency is still insufficient and the airflow cannot be discharged, the internal pressure of the slide 301 will increase, causing the magnet 903 to move toward the inside of the magnet slot, so that the gas inside the magnet slot squeezes the sealing sheet 907, causing the sealing sheet 907 to rise and block the exhaust port on the side, leaving only the exhaust port on the front side, and concentrating the wind pressure to penetrate and blow the straw bag, so that it is quickly dried bit by bit, so as to achieve the purpose of accelerating deep drying.
