Description

Technical Field

[0001] This invention relates to the technical field of biomass liquid fuel feedstock pretreatment equipment, and particularly to an integrated drying and pelletizing machine for biomass liquid fuel feedstock. Background Technology

[0002] Biomass liquid fuel is a liquid fuel produced from biomass such as agricultural and forestry waste, energy crops, or organic waste through physical, chemical, or biological conversion technologies. During processing, the dried raw materials undergo crushing, extrusion, and molding. Larger raw materials are first initially crushed to approximately 5-10 cm in size by a crusher, then evenly fed to the drying unit by a feeder. In the drying unit, the raw materials are in full contact with the heat medium, and moisture escapes from the surface and interior through heat conduction, heat convection, or microwave action until the moisture content drops to below the target value of 10%-15%. The dried raw materials then enter the crushing stage, where they are further refined into 1-2 mm powder by a crusher, and subsequently conveyed to the pelleting unit. In the pelleting unit, the powdered raw materials are extruded by the pressure rollers of the pellet mill, forming particles with a diameter of 3-10 mm and a length of 5-20 mm through die holes.

[0003] The present invention, CN111330515B, discloses a biomass pelletizing machine, including a frame, a feeding cylinder, a rotating shaft, and a motor for driving the rotating shaft. The feeding cylinder is vertically fixed in the middle of the frame, with a bearing seat at its top. A feed hopper communicating with the internal cavity of the feeding cylinder is provided on the upper side wall of the feeding cylinder, and multiple pelleting holes are provided on the lower side wall of the feeding cylinder. The upper end of the rotating shaft is fixed to the bearing seat, and its lower end extends into the feeding cylinder. Spiral blades are provided on the rotating shaft located inside the feeding cylinder. A cutting-off cylinder is sleeved on the outside of the feeding cylinder, and an outlet corresponding to the pelleting holes is opened on the side of the cutting-off cylinder. A cutting-off plate is provided above the outlet. The cutting-off plate gradually slopes downward from the center of the cutting-off cylinder outward. This invention is beneficial for reducing energy consumption, reducing pelleting costs, and improving product quality. It is also simple to operate and facilitates adjustment of the length of the biomass pellet fuel.

[0004] However, during the operation of a flat die pellet mill, due to the design gap between its pelleting roller and the inner wall of the material cylinder, it is difficult to directly contact the cylinder wall. As a result, the material gradually accumulates towards the edge of the cylinder wall under the action of centrifugal force and friction. Especially when processing high-fiber, low-flow-ability materials such as biomass raw materials, these edge-accumulated materials are not only difficult to be effectively compressed, but also form stubborn lumps as the running time increases. As the volume of the lumps continues to increase, the pelleting roller needs to overcome additional resistance when rotating, causing the transmission system to be in an overloaded state for a long time, which seriously affects the service life of the flat die pellet mill. Summary of the Invention

[0005] In view of this, the present invention provides an integrated drying and pelletizing machine for biomass liquid fuel feedstock. It first utilizes a drum dryer to precisely control the moisture content of the raw material to 10%-15%, laying a solid foundation for subsequent pelleting, ensuring the physical properties of the raw material are compatible with the process, reducing transportation losses and time costs, and constructing a continuous and efficient pre-treatment-pelleting chain. Then, a material spreading component and a trumpet-shaped dispersing guide work together to precisely guide the material to the center of the pelleting cylinder, optimizing distribution and ensuring uniform force on the pelleting rollers. This improves the consistency of pellet density and reduces the transmission load on the equipment, breaking the vicious cycle of edge accumulation and overload damage, enhancing equipment stability and pelleting quality. The linkage structure of the pellet adjusting nut-screw-cutting blade allows for flexible adjustment of the cutting blade displacement simply by rotating the nut, precisely controlling the pellet length, breaking through the single length limitation, adapting to the pellet shape requirements of multiple industries, and expanding the equipment's application scenarios. Utilizing the rotational kinetic energy of the pelleting rollers, the push plate is driven to periodically reciprocate inwards and outwards, dynamically clearing accumulated material from the cylinder wall edges without additional power, preventing equipment jamming and wear, reducing manual maintenance costs, and ensuring long-term equipment operation.

Beneficial effects

[0016] This invention utilizes a discharge auxiliary mechanism. The guide drive opens, causing a push rod to move backward. This backward movement of the push rod drives a guide transmission component to move backward, which in turn rotates a guide limiter. The rotation of the guide limiter then rotates a guide plate. At this point, the guide plate guides the first batch of granular material, preventing defective granules from flowing into the next process. After uniform discharge, the timer in the guide drive controls the push rod to reset. This reset of the guide plate guides subsequent granular material, improving the processing quality of the raw material granulation.

[0017] This invention utilizes a material anti-blocking mechanism. Raw materials first enter the drum dryer, where the heat flow dries them, reducing the moisture content to below 10%–15%. The dried material then enters the granulation cylinder. The granulation drive motor is activated, driving the granulation transmission shaft to rotate. This rotation of the transmission shaft causes the material distributor to rotate, evenly dispersing the material onto the top surface of the dispersing guide. Through the funnel-shaped structure of the dispersing guide, the material is added to the center of the granulation cylinder, reducing material accumulation at the inner edge and precisely guiding it to the center. This optimized distribution ensures uniform force on the granulation rollers, improving granule density consistency and reducing equipment transmission load. This breaks the vicious cycle of edge accumulation and overload damage, enhancing equipment stability and granulation quality.

[0018] This invention utilizes a material anti-blocking mechanism. The granulation drive shaft rotates, driving the granulation roller to rotate. The rotating granulation roller extrudes the material through the die holes of the granulation cylinder into strips, which are then granulated by a particle cutter. When it is necessary to produce raw material particles of different lengths, the particle adjusting nut is rotated. The rotation of the particle adjusting nut causes the particle adjusting screw to move up and down, which in turn causes the particle cutter to move up and down. This up-and-down movement of the particle cutter allows for adjustment of the raw material particle length, increasing the applicability of the entire device.

[0019] This invention utilizes a material anti-blocking mechanism. The rotation of the granulation roller also drives the material pusher connector to rotate, which in turn drives the first material pusher trigger to rotate. The first material pusher trigger and the contact surface of the second material pusher trigger come into frictional contact, causing the second material pusher trigger to be squeezed outward. This outward squeezing of the second material pusher trigger causes the anti-accumulation pusher plate to move outward, which in turn causes the material pusher guide rod to move outward. The outward movement of the material pusher guide rod charges the material pusher spring. When the first material pusher trigger rotates to the retraction surface of the second material pusher trigger, the anti-accumulation pusher plate moves inward under the action of the material pusher spring, thus pushing the edge material and preventing edge material accumulation. The pusher plate is driven to periodically reciprocate inward and outward, dynamically clearing the material accumulated on the edge of the cylinder wall without the need for additional power. This prevents equipment jamming and wear, reduces manual maintenance costs, and ensures long-term operation of the equipment. Attached Figure Description

[0049] The specific usage and function of this embodiment are as follows: When granulating raw materials, the raw materials first enter the interior of the drum dryer 4. The heat flow inside the drum dryer 4 dries the raw materials, reducing the moisture content to below 10%~15%. The dried raw materials then enter the granulation cylinder 3. The granulation drive motor 7 is turned on, driving the granulation drive shaft 5 to rotate.
