Description

Technical Field

[0001] This utility model relates to the field of biomass pellet production technology, specifically to a drying device for biomass pellet production. Background Technology

[0002] Biomass pellets are a type of solid fuel made from organic raw materials such as agricultural waste (e.g., straw, bagasse), forestry residues (wood chips, bark), and livestock manure through processes including crushing, drying, and high-temperature pressing. They typically have a diameter of 6-10 mm, high density, and stable calorific value, releasing over 35.9 MJ / kg of heat during combustion. During the production process, biomass pellets need to be dried to remove moisture.

[0003] The double-sided drying oven for processing health tea, as described in publication number CN214426348U, uses a motor to drive a rotating rod, which in turn rotates the oven. Simultaneously, a second gear on the outer wall of the rotating rod meshes with a first gear, causing the first gear to drive a stirring rod. This allows the stirring rod to evenly stir the tea leaves while the oven rotates, ensuring sufficient contact between the tea leaves and the stirring rod. Through vents, a fan, an electric heating device, and air holes, the drying efficiency of the tea leaves is effectively improved. However, the existing technology still has shortcomings:

[0004] In existing technologies, biomass pellets are mostly directly piled inside the drying equipment during the drying process. This prevents the biomass pellets at the bottom from making sufficient contact with the hot air. The pellets are piled together with a high density, resulting in low drying efficiency and inconsistent drying quality.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

[0043] Combined with appendix Figure 1-5 This utility model includes a support frame 1, which is a square placement frame. Fixing blocks 2 are fixedly connected to the four corners of the upper part of the support frame 1. A drying drum 5 is installed on the upper part of the support frame 1. The front end of the drying drum 5 is tapered for easy feeding and discharging. A flipping mechanism 3 is installed at the lower end of the support frame 1, and a base plate 4 is installed at the lower end of the flipping mechanism 3. The flipping mechanism 3 includes a first support rod 301, a second support rod 302, and a cylinder 303. The first support rod 301 is fixedly connected to both ends of the upper front side of the base plate 4, and the upper end of the first support rod 301 is rotated relative to the support frame 1.

Air is blown into the through groove 1002 through the blower 1001 and the air inlet pipe 1003, and then blown into the inside of the drying drum 5 through the through hole 1005, increasing the flow of hot air inside the drum. This makes the biomass pellets heat more evenly, and the drying efficiency is higher and the quality is better.

[0048] In specific implementation of this utility model, as shown in the figure, the sealing cover 7 is opened, biomass pellets are put into the drying drum 5, the sealing cover 7 is closed again, the electric heating tube 1007 is turned on to evenly heat the inner wall of the drying drum 5, increasing the temperature inside the drum to bake the biomass pellets, the blower 1001 and the air inlet pipe 1003 are turned on to blow air into the through groove 1002, and then blown into the drying drum 5 through the through hole 1005 to increase the flow of hot air inside the drum and improve the drying efficiency, the motor 607 is turned on to drive the drying drum 5 to rotate through the rotating mechanism 6, so that the biomass pellets inside the drying drum 5 are evenly heated. The pellets are constantly tumbling, and as the drying drum 5 rotates, they move to a high position and then fall under gravity, making the biomass pellets heat more evenly. The motor 903 is started, which drives the scraper 905 and the stirring rod 906 to rotate through the mixer 9, stirring the biomass pellets in the drum, making the biomass pellets more dispersed, increasing the gaps between the pellets, and facilitating even heating.
