Description

Technical Field

[0001] This utility model relates to the field of straw drying technology, and in particular to a straw drying device for biofuel preparation. Background Technology

[0002] Biofuels are produced using solid waste from agricultural crops such as corn stalks, wheat straw, rice straw, peanut shells, corn cobs, cotton stalks, soybean stalks, weeds, branches, leaves, sawdust, and bark as raw materials. These materials are crushed, compressed, densified, and shaped into small rod-shaped solid pellet fuels. Pellet fuel is produced by extruding raw materials such as sawdust and straw using rollers and ring dies at room temperature, making transportation and storage extremely convenient. Simultaneously, its combustion performance is greatly improved. The preparation of straw fuel must involve drying. If it is compressed while still moist, not only will the compression effect be poor, but the compressed straw fuel will also be difficult to store, has a short storage time, and is prone to mold, which is detrimental to its subsequent use as biofuel. Therefore, we propose a straw drying device for biofuel preparation. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a straw drying device for biofuel preparation. This invention solves the problem that pressing straw while it still contains moisture not only results in poor pressing efficiency but also makes the pressed straw fuel difficult to store, prone to mold growth during short storage periods, and detrimental to subsequent biofuel use.

[0004] This utility model discloses a straw drying device for biofuel preparation, comprising a workbench, an active shaft on one side of the upper end of the workbench, a driven shaft on the other side of the workbench, gears at both ends of the active and driven shafts, transmission wheels on the side of the active and driven shafts near the gears on the workbench, two transmission wheels on the same side of the workbench being connected by a transmission belt, multiple equally spaced support rods between the two transmission belts, a housing in the middle of the upper part of the workbench, a drying chamber in the upper part of the housing, an electric heating tube in the upper part of the drying chamber, and multiple matrix-arranged air outlets in the lower part of the drying chamber.

[0005] In the above scheme, a support frame is provided on one side of the shell, and a fan is fixedly installed on the support frame. The air outlet of the fan is connected to the drying box through an air inlet pipe.

[0006] In the above scheme, the air inlet end of the fan is equipped with a filter screen.

[0007] In the above scheme, the worktable is provided with a mounting bracket on the side near the drive shaft, and a motor is fixedly mounted on the mounting bracket. The motor's rotating shaft passes through the mounting bracket and is fixedly connected to the first pulley. The drive shaft passes through the worktable and is fixedly connected to the second pulley. The first pulley and the second pulley are connected by belt drive.

[0008] In the above scheme, through grooves are provided on both sides of the housing.

[0009] The advantages and beneficial effects of this utility model are as follows: This utility model provides a straw drying device for biofuel preparation. A motor drives a first pulley to rotate, and through belt transmission, a second pulley drives a drive shaft to rotate. When the drive shaft rotates, the gears and transmission wheels at both ends of the drive shaft also rotate. Through the transmission belt, the driven shaft drives the gears and transmission wheels on the driven shaft to rotate. When the gears rotate, they push the support rod, thus transporting the straw to be dried. Airflow enters the drying chamber through the air inlet pipe. When the airflow passes through the electric heating tube, the electric heating tube heats the airflow. The heated airflow is then blown directly onto the straw to be dried through the air outlet, thereby achieving the purpose of drying the straw. This drying device has a simple structure, facilitates the loading and unloading of straw, has a good drying effect, and effectively improves the quality of the subsequent biomass fuel product.

Two transmission wheels 5 on the same side of the workbench 1 are connected by a transmission belt 6. Multiple equally spaced support rods 7 are provided between the two transmission belts 6. When the drive shaft 2 rotates, the two support rods 7... The gear 4 and transmission wheel 5 at the end also rotate. Through the transmission belt 6, the driven shaft 3 can drive the gear 4 and transmission wheel 5 on the driven shaft 3 to rotate. When the gear 4 rotates, the gear 4 can push the support rod 7, so that the support rod 7 can transport the straw to be dried. The upper middle part of the workbench 1 is provided with a shell 8. The upper end of the shell 8 is provided with a drying box 9. The upper end of the drying box 9 is provided with an electric heating tube 10.

[0021] Both sides of the shell 8 are provided with through grooves 21, through which the straw to be dried can enter the interior of the shell 8.

[0022] Specifically, in this utility model, when drying straw, the straw is laid flat on the support rod 7. When the motor 17 is working, the motor 17 drives the first pulley 18 to rotate. Through the transmission of the belt 20, the second pulley 19 can drive the drive shaft 2 to rotate. When the drive shaft 2 rotates, the gears 4 and transmission wheels 5 at both ends of the drive shaft 2 also rotate. Through the transmission of the transmission belt 6, the driven shaft 3 can drive the gears 4 and transmission wheels 5 on the driven shaft 3 to rotate. When the gears 4 rotate, the gears 4 can push the support rod 7, so that the support rod 7 can transport the straw to be dried. When the fan 13 is working, the fan 13 can drive the airflow, so that the airflow enters the drying chamber 9 through the air inlet pipe 14. When the airflow passes through the electric heating tube 10, the electric heating tube 10 heats the airflow. The heated airflow blows directly onto the straw to be dried through the air outlet 11, thereby achieving the purpose of drying the straw.
