Description

Technical Field

[0001] The present invention relates to the application field of biomass fuel, in particular to a novel biomass powder continuous drying device. Background Art

[0002] Biomass refers to various organisms produced through photosynthesis using the atmosphere, water, land, etc., that is, all living organic matter that can grow is collectively called biomass. Biomass includes plants, animals and microorganisms. Biomass energy is a renewable energy source. By converting these biomass resources into powder form, they can be more conveniently stored, transported and further processed and utilized.

[0003] Biomass powder usually contains a high amount of moisture, which affects its combustion performance and utilization efficiency. Therefore, drying is an indispensable part of the biomass powder processing process. Drying can reduce the moisture content of biomass powder and improve its calorific value and combustion performance. Biomass powder is usually dried using a drum dryer, which uses electric heating and drum stirring to quickly dry the biomass powder and reduce the moisture content in the biomass material.

[0004] The drum dryer has the advantages of large processing capacity and high efficiency, and is suitable for large-scale production in factories. However, when using biomass fuel for household use, it will be directly crushed and then burned. Then the drying equipment and combustion furnace of biomass powder will be used in combination. The amount of biomass fuel required for combustion is small, and quantitative control is required when adding it. Therefore, the traditional drum dryer is not suitable for household use and cannot quantitatively add the dried biomass fuel into the combustion furnace. Summary of the Invention

[0017] By adopting the above technical solution, a through groove is set inside the cylinder, so that when the roller feeding assembly moves into the drying hood, the second heating rod can be inserted into the cylinder, and then the biomass is dried from the inside of the cylinder, thereby improving the drying efficiency.

The drying hood 7 can dry the biomass powder stored in the roller feeding assembly 2, and a feeding pipe 10 is provided on the side of the drying hood 7. A first heating rod 8 and a second heating rod 9 are installed inside the drying hood 7, and a magnetic attraction assembly 11 is movably installed inside the drying hood 7. The magnetic attraction assembly 11 is an electromagnetic attraction device, which can generate a strong electromagnetic force when the power is turned on, and one end of the magnetic attraction assembly 11 is connected to the second telescopic assembly 12, which can drive the magnetic attraction assembly 11 to move.

[0043] See also Figure 3 and Figure 4 The roller feeding assembly 2 includes a cylinder 201, and a storage bin 202 is provided inside the cylinder 201, and mounting holes 203 are provided on both sides of the storage bin 202 inside the cylinder 201, a spring 204 is installed inside the mounting hole 203, and a cover plate 3 is movably installed inside the mounting hole 203. By arranging the storage bin 202 outside the cylinder 201, it can be used to store biomass powder, and the storage bin 202 is sealed by arranging the spring 204 and the cover plate 3 to prevent the biomass powder from scattering during the drying process.

[0044] See also Figure 4 There are multiple groups of storage bins 202, and the multiple groups of storage bins 202 are evenly distributed on the radial side of the cylinder 201. By setting the multiple groups of storage bins 202 outside the cylinder 201, the cylinder 201 can be rotated to load and unload materials.

[0045] See also Figure 6The cover plate 3 includes a ceramic filter membrane 301, and a metal plate 302 is provided at one end of the ceramic filter membrane 301, and a linkage plate 303 is provided on the top of the metal plate 302. The linkage plate 303 is inserted into the interior of the mounting hole 203, and the linkage plate 303 fits tightly with the spring 204. By setting the cover plate 3, the storage bin 202 can be blocked to prevent the biomass powder of the roller feeding assembly 2 from falling during the movement or drying process, and the cover plate 3 can be opened during loading and unloading to ensure normal operation.

[0046] See also Figure 6 The ceramic filter membrane 301 is made of a high-temperature sintered ceramic material, and its pore size is usually between 0.2-0.5 microns, which can effectively filter water vapor. By setting the ceramic filter membrane 301, water vapor can be effectively filtered so that the water vapor evaporated from the drying of the wet biomass powder can be discharged from the storage bin 202.

[0047] See also Figure 4 A through groove 205 is provided inside the cylinder 201, and the through groove 205 matches the second heating rod 9. By providing the through groove 205 inside the cylinder 201, when the roller feeding assembly 2 moves into the drying hood 7, the second heating rod 9 can be inserted into the inside of the cylinder 201, and then the biomass is dried from the inside of the cylinder 201, thereby improving the drying efficiency.

[0048] See also Figure 2 A push rod 6 is installed on the inner wall of the protective cabin 1, and the push rod 6 can push the cover plate 3 to move. By setting the push rod 6, when the roller feeding assembly 2 moves, the push rod 6 can squeeze the cover plate 3 to realize the opening of the cover plate 3.

[0049] See also Figure 2 A loader 14 is provided on one side of the protective cabin 1, and one end of the loader 14 is located above the feed port 13. The loader 14 is a material elevator. By setting up the loader 14, the biomass powder can be transported to the feed port 13.

[0050] See also Figure 1 An air circulation device 15 is installed on the top of the protection cabin 1. The air circulation device 15 can promote the exchange of water vapor inside the protection cabin 1 and external air. By setting up the air circulation device 15, the water vapor in the protection cabin 1 can be discharged, while reducing the internal pressure of the protection cabin 1 and improving the drying effect of the biomass powder.

[0051] See also Figure 10 The discharge pipe 10 is installed at the bottom of the drying hood 7, and the discharge pipe 10 extends to the outside of the protective cabin 1, and the end of the protective cabin 1 is connected to the combustion furnace. By setting the discharge pipe 10 to connect the combustion furnace, the dried biomass powder can be directly put into the combustion furnace for use.

[0052] The working principle of the present invention is as follows: the biomass powder is transported by the feeder 14 and added into the protective cabin 1 from the feed port 13. The first telescopic component 5 contracts to drive the roller feeding component 2 to move to the bottom of the feed port 13. During the movement of the roller feeding component 2, the push rod 6 squeezes the cover plate 3. The linkage plate 303 in the cover plate 3 slides inside the mounting hole 203 and squeezes the spring 204, causing the spring 204 to contract. The roller feeding component 2 moves to the storage bin 202 below the feed port 13. The feed port 13 is opened. The control valve is opened, and the biomass powder fills the storage bin 202. Then the first telescopic component 5 extends to push the roller feeding component 2 to reset its position, and the cover plate 3 will reclose the storage bin 202 under the reset action of the spring 204. Then the driving component 4 works to drive the roller feeding component 2 to rotate a certain angle, so that the other group of storage bins 202 rotates to the bottom of the feed port 13. According to the above steps, the storage bin 202 is filled with biomass powder until all the storage bins 202 in the cylinder 201 are filled.

[0053] Next, the first telescopic component 5 extends to push the roller loading component 2 into the interior of the drying hood 7, and the power of the first heating rod 8 and the second heating rod 9 is turned on. The first heating rod 8 and the second heating rod 9 generate heat to dry the roller loading component 2. At the same time, the driving component 4 drives the roller loading component 2 to rotate slowly, so that the biomass powder can be dried more evenly and quickly. The second heating rod 9 will be inserted into the interior of the through groove 205 to dry the biomass powder from the inside and outside of the cylinder 201.

[0054] After a period of drying, the dried biomass powder needs to be put into the combustion furnace for use. The power of the magnetic component 11 is turned on, and the electromagnetic attraction force is used to make the magnetic component 11 firmly adsorb the corresponding metal plate 302. Then the second telescopic component 12 is started. The second telescopic component 12 drives the magnetic component 11 to contract, so that the cover 3 is opened, so that the biomass powder inside the storage bin 202 falls into the inside of the discharge pipe 10, and the negative pressure inside the combustion furnace connected to the discharge pipe 10 will suck the biomass powder into the combustion chamber for combustion. Similarly, the driving component 4 drives the roller feeding component 2 to rotate so that all the biomass powder inside can be put into the discharge pipe 10 according to the amount.

[0055] The ceramic filter membrane 301 is made of a high-temperature sintered ceramic material, and its pore size is usually between 0.2-0.5 microns. It can effectively filter water vapor and improve the drying efficiency of the drying hood 7 for biomass powder. Since the drying hood 7 is provided with an opening, a large amount of water vapor in the drying chamber will pass through the ceramic filter membrane and the opening of the drying hood 7 into the interior of the protective cabin 1. Starting the air circulation device 15 can discharge the water vapor inside the protective cabin 1.
