Description

Technical Field

[0001] The present invention relates to the technical field of liquid fuel raw material preparation, in particular to a biomass liquid fuel raw material molding and preparation device. Background Art

[0002] The pretreated biomass raw materials need to be prepared into high-density blocks through a stamping machine to facilitate the raw materials to adapt to conversion processes such as pyrolysis and gasification. During the preparation process, the raw materials need to be added to the molding mold first. When adding raw materials to the mold cavity, the materials are often accumulated in the middle of the mold at the beginning, and then gradually roll and diffuse to the surrounding areas as the amount added increases. When the raw materials are added, the punch will reciprocate at high speed driven by the power device to apply instantaneous high pressure to the material. The pressure applied by the punch will cause the material to roll faster, thereby making the surface smooth. After the raw materials are subjected to high pressure, the cellulose, hemicellulose and other components in them are interlocked with each other through intermolecular forces or a small amount of added adhesives. The compacted block material is pushed out through the mold outlet to form a high-density block of regular shape.

[0003] For example, CN118834710B discloses a ring die pelletizing and briquetting multifunctional all-in-one machine, which relates to the technical field of pelletizing and briquetting. The all-in-one machine includes a hopper, a distribution box, a discharge box, and a pelletizing and briquetting box. A hopper is installed above the distribution box, and discharge boxes are installed on both sides below the distribution box. The two discharge boxes are respectively connected to the pelletizing and briquetting boxes, and one side of the two pelletizing and briquetting boxes is commonly connected to a transmission box. The input end of the transmission box is connected to a driving motor. When the driving motor rotates forward or reverse, only one pelletizing and briquetting box works. The pelletizing and briquetting box in the working state granulates or briquettes the raw materials, and the distribution box cooperates with the work of the driving motor to distribute the raw materials to the corresponding pelletizing and briquetting boxes. The present invention integrates the two processes of pelletizing and briquetting into one device, which solves the problem that multiple devices occupy a large space. At the same time, the present invention can directly switch the pelletizing process and the briquetting process without stopping the machine, thereby improving work efficiency and reducing the problems of low work efficiency and low production capacity caused by shutdown.

[0004] However, when the middle material is piled too thick, the resistance to the flow of material to the surrounding areas during the compression process is relatively large, making it difficult to fully fill the gaps at the edge of the mold. During stamping, the middle material will preferentially contact the punch and bear the main pressure, while the surrounding material cannot be sufficiently compacted due to insufficient filling, which ultimately leads to the phenomenon of high density in the middle area and low density around the molding raw material, affecting the effects of subsequent pyrolysis and gasification processes, and thus affecting the processing quality of liquid fuel. Summary of the Invention

[0005] In view of this, the present invention provides a biomass liquid fuel raw material molding and preparation device, which effectively improves the raw material taking efficiency, reduces the device downtime, improves the production continuity of the raw material preparation device, avoids the inconvenience of the staff putting their hands into the mold to take the material, reduces the safety hazard, and avoids the problem of damage to the raw materials after molding due to manual operation errors, and avoids the situation where the raw material particles are too large to affect the molding effect. At the same time, the rotation and vibration of the raw material screening mesh can improve the screening efficiency of the raw material, can make the raw material dispersed evenly, and can automatically shake off the fine powder adhering to the mesh, avoids the situation where the raw material screening mesh is blocked due to material accumulation, reduces the frequency of manual cleaning, and avoids the problem of raw material being blocked. The material enters the meshing of the driven drive gear and the active drive gear and causes mechanical jamming, which significantly improves the reliability of the device operation and the service life of the device, reduces the frequency of maintenance of the device, and can make the raw materials accumulated in the middle spread evenly to the edge of the mold, and simultaneously eliminate the height difference of the raw material surface, ensuring that the raw materials can fully fill the gaps at the edge of the mold, further improving the uniformity of the laying of the raw materials, making the raw materials evenly compressed, ensuring that the raw materials can be fully compacted, ensuring that the raw materials after molding can obtain consistent density, improving the molding effect of the raw materials, avoiding the situation where the molding raw materials have high density in the middle area and low density around, ensuring the effect of subsequent pyrolysis and gasification processes, and thus improving the processing quality of liquid fuel.
