[0002] In the biomass pellet industry, as one of the most important equipment, the horizontal granulator is used for pressing and forming the die (ring die), which is the most important functional part of the granulator. During use, the production cost is high due to the important and easily damaged part. The conventional ring die for horizontal granulator adopts a single working surface. During use, when the single working surface is worn to a certain extent, the die is scrapped. The production cost is high due to the single output.
[0003] According to the above situation, through the upgrading and improvement of the structure, the double-sided ring die for horizontal granulator is obtained, that is, one ring die has two symmetrical working surfaces. After one working surface is used up, the other working surface is exchanged for continuous use, which effectively reduces the production cost. The design idea of the ring die for horizontal granulator is that due to the adoption of double working surfaces, the overall length is slightly longer than that of the original ordinary ring die. The installation strength needs to be considered. For this installation structure, the company adopts the bolt tensioning and inclined surface block type fixing method, which effectively improves the defect of insufficient connection strength of the original ring die.

An inclined pressure block 5 is fixedly connected inside the ring die drive wheel 2 for interconnecting with a first fixed inclined surface 10 and a second fixed inclined surface 12, thereby pressing the ring die 3 with radial pressure. Multiple sets of inclined pressure blocks 5 are provided, each connected to a first fixed inclined surface 10 and a second fixed inclined surface 12. The ring mold drive wheel 2 is detachably connected to the ring mold 3 for processing biological pellets. The outer surface of the ring mold drive wheel 2 is fixedly connected to the main shaft 15, which is rotatably connected to the inside of the gearbox 1.
[0027] The outer surface of the ring die 3 is detachably connected to a clamp 6 to prevent powder leakage, reinforce the ring die 3, and protect the unused working surface of the ring die 3. A pressure mold cover 7 is fixedly connected to the outer surface of the ring die 3 to protect the pressure film. A fixing keyway 8 is provided on the outer surface of the ring die 3 for radial torque. Tension bolt holes 9 are provided on the outer surface of the ring die 3 for connecting bolts, making the ring die 3 easy to install and fix.

The two working surfaces on the ring die 3 enable double-sided use of the ring die 3, greatly improving its service life. The outer surface of the ring die 3 is provided with fixing inclined surface one 10 and fixing inclined surface two 12 for interconnection with the inclined surface pressure block 5, making the ring die 3 easy to fix and switch between working surface one 11 and working surface two 13. The ring die drive wheel 2 has an internal threaded connection with a tension bolt 4, which is used to fix the ring die 3 to make its connection with the ring die drive wheel 2 more stable and to apply axial tension to the ring die. The tension bolt 4 is fixedly connected to the ring die 3 through the tension bolt hole 9.
[0028] The gearbox 1 has a large gear 17 connected to its internal shaft, which connects to the gear shaft 19 for transmission. The large gear 17 meshes with the gear shaft 19, which connects to the main shaft 15 for power transmission. A sealing cover 21 is fixedly connected inside the gearbox 1, serving a sealing function to protect the internal steel sleeve 20 and prevent the grease inside from leaking out. The steel sleeve 20 is located inside the sealing cover 21, positioning the main shaft 15 and making its rotation smoother, reducing the friction generated during rotation. The steel sleeve 20 is slidably connected to the outer surface of the main shaft 15. A stainless steel disc 23 is fixedly connected to the outer surface of the gearbox 1 to protect the ring die drive wheel 2.

[0029] Working principle: In use, the fixed inclined surface 10 on the ring die 3 is installed on the inclined pressure block 5 on the ring die drive wheel 2. The fixed inclined surface 10 is pressed and fixed by the inclined pressure block 5. The ring die 3 is fixed on the ring die drive wheel 2 by the tension bolt 4 through the tension bolt hole 9. The compression mold cover 7 is installed on the ring die 3. The ring die drive wheel 2 and the main shaft 15 inside the gearbox 1 are installed together to achieve synchronous rotation. The large gear 17 and the gear shaft 19 installed inside the gearbox 1 mesh to achieve internal transmission. The ring die 3 is rotated by the ring die drive wheel 2 installed on the main shaft 15. Under the power input of the gearbox 1, the ring die 3 is driven to rotate clockwise. The material is squeezed into granules through the compression hole of the ring die 3 by the rotation of the internal pressure roller.
[0030] When the service life of working surface 11 on ring die 3 reaches its limit, the fixed inclined surface 10 pressed by the inclined surface pressure block 5 is released from ring die 3, and the connecting parts on ring die 3 are removed. Then, the fixed inclined surface 12 and the inclined surface pressure block 5 on ring die 3 are connected and fixed to each other, so that working surface 11 can be switched to working surface 13 for use. Working surface 11 and working surface 13 are arranged symmetrically, and fixed inclined surface 10 and fixed inclined surface 12 are also arranged symmetrically.
