Description

Technical Field

[0001] This utility model relates to the field of pulverization technology, and more specifically, to a raw material pulverizing device for biochar processing. Background Technology

[0002] In existing raw material crushing devices for biochar processing, there is a common problem that the installation and disassembly of the screen plate are inconvenient, which causes a lot of trouble in actual production.

[0003] First, the screen plate structure is relatively fixed but lacks flexibility. In existing devices, the screen plate is mostly fixed inside the crushing chamber by bolts, slots, or welding. Although this method can ensure that the screen plate is not easily loosened during operation, the operation process is often cumbersome when the screen plate needs to be replaced or cleaned. The staff must use tools to disassemble the fixing parts one by one, which consumes a lot of time and energy and affects production efficiency.

[0004] Secondly, the screen plate is prone to clogging and wear, requiring frequent maintenance. Due to the varying sizes of the crushed raw material particles, some larger particles can easily clog the screen holes, resulting in reduced screening efficiency and potentially affecting the normal discharge of materials. Therefore, the screen plate needs to be cleaned or replaced regularly. However, due to the inconvenience of installation and disassembly, each maintenance operation requires a long downtime, leading to a decrease in equipment utilization and increased production costs.

A ratchet paddle 12 is installed at the outer end of the longitudinal sliding ring 11. The rotation of the limiting rotating ring 101 causes the embedded plate 9 to extend into or away from the locking rod 7.

[0023] In this embodiment, the feeding hopper 18 is connected to the crushing box 1. The raw material is fed into the crushing box 1 from the top. The crushing shaft assembly 4 rotates within the crushing box 1, and the drive wheel 5 installed at one end is connected to an external drive system to provide crushing power. After the raw material is crushed by the crushing shaft assembly 4, the crushed material is discharged through the discharge hopper 2 installed at the bottom of the crushing box 1. The screen plate 3 is detachably installed at the outlet end of the discharge hopper 2 to screen and classify the crushed material to ensure that the output particle size meets the requirements. The frame 17 is installed at the bottom end of the crushing box 1 and contacts the ground for support, providing a stable support platform for the entire device. The clamping pipe 6 is fixedly installed on the mounting plate 19 of the screen plate 3, and the clamping rod 7 is installed on the discharge hopper 2. On bucket 2, one end passes through discharge bucket 2 and mounting plate 19 and engages with locking pipe 6. Limiting ring 101 is installed on the outer wall of locking pipe 6 to limit rotation.

Embedded plate 9 extends into or away from locking rod 7 to achieve quick locking or release of screen plate 3 and discharge bucket 2.

[0024] The snap-fit ​​auxiliary mechanism includes an outer rotating ring 13 and a rotating plate 14. The outer rotating ring 13 is rotatably mounted on the outer wall of the snap-fit ​​tube 6. The outer rotating ring 13 is threadedly connected to the longitudinal moving ring 11. The rotation of the outer rotating ring 13 causes the longitudinal moving ring 11 to move longitudinally. Multiple sets of rotating plates 14 are mounted on the top end of the outer rotating ring 13. An outer retaining ring 15 is fixedly mounted on the outer wall of the snap-fit ​​tube 6. A positioning spring 16 is mounted on the outer retaining ring 15. The positioning spring 16 extends into different rotating plates 14 in stages to make the outer rotating ring 13 rotate stably.

[0025] In this embodiment, the outer rotating ring 13 is rotatably limited and mounted on the outer wall of the clamping tube 6, and is threadedly connected to the longitudinal moving ring 11.

When the rotation limiting ring 101 locks the clamping rod 7, the outer rotating ring 13 is rotated, and the threaded connection causes the longitudinal moving ring 11 to move longitudinally, adjusting the contact state between the ratchet pawl 12 and the ratchet ring 10. The positioning spring 16 and the rotating plate 14 cooperate to ensure that the outer rotating ring 13 rotates stably and is positioned. When the ratchet pawl 12 contacts and supports the ratchet ring 10, it prevents the rotation limiting ring 101 from rotating in the opposite direction, forming a double safety locking mechanism.

[0026] Please see Figures 1-5 As a supplementary embodiment of a raw material crushing device for biochar processing, which includes a crushing and discharge mechanism, a sieve plate replacement mechanism, and a clamping auxiliary mechanism: A frame 17 is installed at the bottom of the crushing box 1, and the frame 17 is supported in contact with the ground. An adding hopper 18 is installed at the top of the crushing box 1, and the adding hopper 18 is connected to the crushing box 1. An installation plate 19 is installed on the sieve plate 3, and a clamping pipe 6 is fixedly installed on the installation plate 19. A connecting plate 20 is installed at the bottom of the side wall of the clamping pipe 6, and the connecting plate 20 is fixedly installed on the installation plate 19. A clamping rod 7 is installed on the discharge hopper 2, and one end of the clamping rod 7 passes through the discharge hopper 2 and the installation plate 19 to engage with the clamping pipe 6. A centripetal rail 21 is installed on one end face of the connecting plate 20, and an embedded plate 9 is slidably arranged in a centripetal manner with the centripetal rail 21. A guide block 22 is installed at the top of the embedded plate 9, and the guide block 22 is slidably connected with the arc groove 8.

[0027] More specifically, biochar processing raw materials are fed into the crushing box 1 by adding bucket 18. Frame 17 provides stable support. The external drive setting is activated, driving wheel 5 to drive the crushing shaft assembly 4 to rotate in the crushing box 1, crushing the raw materials. The crushed material is discharged through discharge bucket 2. Screen plate 3 screens and grades the material to ensure that the output particle size meets the standard. Rotating the limiting ring 101 drives the embedded plate 9 to slide centripetally through the arc groove 8. The embedded plate 9 moves away from the locking rod 7, releasing the connection between the screen plate 3 and the discharge bucket 2. Screen plates 3 of different specifications can be quickly replaced. After installing the new screen plate 3, the limiting ring 101 is rotated in the opposite direction, and the embedded plate 9 extends into the locking rod 7 to achieve a quick locking connection. Rotating the outer rotating ring 13 adjusts the position of the longitudinal moving ring 11, so that the ratchet paddle 12 contacts and supports the ratchet ring 10, preventing the limiting ring 101 from loosening accidentally. The positioning spring 16 cooperates with the rotating plate 14 to ensure that the outer rotating ring 13 is stably positioned. After locking, the crushing operation continues to achieve the processing of biochar raw materials with different particle size requirements.

[0028] In summary, during the use or operation of the overall equipment: when the crushing and discharge mechanism is in operation, the adding hopper 18 is connected to the crushing box 1, and the raw material is fed into the crushing box 1 from the top. The crushing shaft assembly 4 rotates within the crushing box 1, and the drive wheel 5 installed at one end is connected to an external drive system to provide crushing power. After the raw material is crushed by the crushing shaft assembly 4, the crushed material is discharged through the discharge hopper 2 installed at the bottom of the crushing box 1. The screen plate 3 is detachably installed at the outlet end of the discharge hopper 2 to screen and classify the crushed material to ensure that the output particle size meets the requirements. The frame 17 is installed at the bottom of the crushing box 1 and contacts the ground for support, providing a stable support platform for the entire device.

[0029] When the screen plate replacement mechanism is in operation, the clamping pipe 6 is fixedly installed on the mounting plate 19 of the screen plate 3, and the clamping rod 7 is installed on the discharge hopper 2. One end of the rod passes through the discharge hopper 2 and the mounting plate 19 and engages with the clamping pipe 6. The limiting ring 101 is installed on the outer wall of the clamping pipe 6 to limit rotation, and a ratchet ring 10 is installed at the top end. The embedded plate 9 is slidably installed on the side wall of the clamping pipe 6 and is slidably connected with the arc groove 8 on the limiting ring 101. The guide block 22 installed at the top end of the embedded plate 9 is slidably connected with the arc groove 8. The connecting plate 20 is equipped with a centripetal rail 21 and is slidably connected with the embedded plate 9. When the screen plate 3 needs to be replaced, the limiting ring 101 is rotated, and the arc groove 8 drives the embedded plate 9 to slide centripetally through the centripetal rail 21. The embedded plate 9 extends into or away from the clamping rod 7, realizing the quick locking or release of the screen plate 3 and the discharge hopper 2.

[0030] When the locking auxiliary mechanism is required to operate, the outer rotating ring 13 is limited to rotate and installed on the outer wall of the locking tube 6, and is threadedly connected to the longitudinal moving ring 11. The longitudinal moving ring 11 is longitudinally slidably installed on the outer wall of the locking tube 6, and a ratchet pawl 12 is installed at its outer end. Multiple sets of rotating plates 14 are installed at the top end of the outer rotating ring 13, and the outer fixing ring 15 is fixedly installed on the outer wall of the locking tube 6. The installed positioning springs 16 extend into different rotating plates 14 in stages. After the limiting ring 101 locks the locking rod 7, the outer rotating ring 13 is rotated, and the threaded connection causes the longitudinal moving ring 11 to move longitudinally, adjusting the contact state between the ratchet pawl 12 and the ratchet ring 10. The positioning spring 16 and the rotating plate 14 cooperate to ensure that the outer rotating ring 13 rotates and is positioned stably. When the ratchet pawl 12 contacts and supports the ratchet ring 10, it prevents the limiting ring 101 from rotating in the opposite direction, forming a double safety locking mechanism.

[0031] The raw materials for biochar processing are fed into the crushing chamber 1 through the addition hopper 18. The frame 17 provides stable support. The external drive setting is activated, which drives the wheel 5 to drive the crushing shaft assembly 4 to rotate in the crushing chamber 1 to crush the raw materials. The crushed material is discharged through the discharge hopper 2. The screen plate 3 screens and grades the material to ensure that the output particle size meets the standard. The rotation limiting ring 101 is rotated, and the embedded plate 9 is driven to slide centripetally through the arc groove 8. The embedded plate 9 moves away from the locking rod 7, releasing the connection between the screen plate 3 and the discharge hopper 2. The screen plate 3 of different specifications can be quickly replaced. After installing the new screen plate 3, the rotation limiting ring 101 is rotated in the opposite direction, and the embedded plate 9 extends into the locking rod 7 to achieve a quick locking connection. The outer rotating ring 13 is rotated, and the position of the longitudinal moving ring 11 is adjusted so that the ratchet pawl 12 contacts the ratchet ring 10 for support, preventing the rotation limiting ring 101 from loosening accidentally. The positioning spring 16 cooperates with the rotating plate 14 to ensure that the outer rotating ring 13 is stably positioned. After locking, the crushing operation continues to achieve the processing of biochar raw materials with different particle size requirements.
