[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5One embodiment shown is as follows: A biocarbon source storage tank 1 with anti-crystallization stirring device includes a storage tank 1. In this embodiment, the storage tank 1 serves as the basic supporting component of the entire device and is used to store biocarbon sources. A rotatable main stirring shaft 2 is rotatably connected inside the storage tank 1. The main stirring shaft 2 is connected to the storage tank 1 via bearings and other rotatable connecting parts. This connection method allows the main stirring shaft 2 to rotate smoothly inside the storage tank 1, providing the power basis for subsequent stirring and crystal collection. Several horizontal stirring components 3 are respectively arranged on both sides of the main stirring shaft 2. These horizontal stirring components 3 are evenly distributed around the circumference of the main stirring shaft 2. When the main stirring shaft 2 rotates, the horizontal stirring components 3 can rotate synchronously, expanding the range of stirring and crystal collection. A closed cavity 4 is opened inside the main stirring shaft 2. The closed cavity 4 is a relatively sealed space, providing conditions for subsequent adjustment of the position of the sliding rod 6. A connecting cavity 5 is respectively arranged on both sides of the main stirring shaft 2, communicating with the closed cavity 4. The connecting cavity 5 is connected to the closed cavity 4 through a channel, allowing pressure changes in the closed cavity 4 to be transmitted to the connecting cavity 5. The horizontal stirring assembly 3 includes a sliding rod 6 that can slide within the connecting cavity 5. The sliding rod 6 and the connecting cavity 5 are fitted with a clearance fit, ensuring smooth sliding of the sliding rod 6 within the connecting cavity 5 while preventing excessive leakage of the biochar source. A collection housing 7 is located at the end of the sliding rod 6 furthest from the main stirring shaft 2. The collection housing 7 is fixed to the sliding rod 6 by welding or bolting. When the main stirring shaft 2 rotates, it drives the sliding rod 6, which in turn drives the collection housing 7 to rotate. A collection hopper 8 is provided at the inlet end of the collection housing 7. The collection hopper 8 is integrally formed with the collection housing 7 or connected by welding or other methods. A filter hole 9 is provided on the collection hopper 8 to filter impurities in the biochar source, allowing only crystals and a portion of the liquid to enter the collection housing 7.

[0023] The implementation principle of the above embodiment is as follows: the main stirring shaft 2 rotates, and the main stirring shaft 2 drives the horizontal stirring component 3 to rotate. During the rotation of the collection shell 7 with the main stirring shaft 2, the biological carbon source containing crystals is brought into the collection shell 7 from the collection hopper 8 by using centrifugal force and fluid inertia, so as to collect the crystals.

[0024] Reference Figure 3 , Figure 4One embodiment is shown: a crushing assembly 10 for crushing crystals is provided inside the collection housing 7. In this embodiment, the crushing assembly 10 is used to crush the crystals entering the collection housing 7. The crushing assembly 10 includes a first crushing roller 11 and a second crushing roller 12. Both the first crushing roller 11 and the second crushing roller 12 are rotatably connected to the collection housing 7 via bearings. This rotatable connection allows the first crushing roller 11 and the second crushing roller 12 to rotate freely within the collection housing 7. Crushing teeth are fixed to both the first crushing roller 11 and the second crushing roller 12. The crushing teeth are fixed to the roller body by welding or embedding. The crushing teeth on the first crushing roller 11 and the second crushing roller 12 are staggered for crushing the crystals. Gears 13 are coaxially arranged on both the first crushing roller 11 and the second crushing roller 12. The gears 13 are connected to the roller body by key connection or interference fit to ensure synchronous rotation between the gears 13 and the roller body. The two gears 13 mesh with each other, enabling the first crushing roller 11 and the second crushing roller 12 to rotate relative to each other. A micro motor 14 is fixedly installed inside the collection housing 7. The micro motor 14 is fixed inside the collection housing 7 by bolts or welding. The output end of the micro motor 14 is connected to one of the gears 13, and power is transmitted through couplings and other connecting parts.

[0025] The implementation principle of the above embodiment is as follows: the micro motor 14 starts and drives the gear 13 connected to it to rotate. Through the meshing action between the gears 13, the first crushing roller 11 and the second crushing roller 12 rotate relative to each other, and the crushing teeth on them crush the crystals that enter the collection shell 7.

[0026] Reference Figure 2 One embodiment shown is as follows: A plurality of filter screens 15 are provided at the outlet end inside the collecting housing 7. In this embodiment, the filter screens 15 are fixed to the outlet end inside the collecting housing 7 by means of slots or bolts, and are used to filter the crushed crystals. A plurality of heating blocks 16 are also provided at the outlet end inside the collecting housing 7. The heating blocks 16 are fixed inside the collecting housing 7 by bolts or welding. The filter screens 15 and the heating blocks 16 are staggered, which allows the crushed crystals to fully contact the heating blocks 16 while being filtered by the filter screens 15.

[0027] The implementation principle of the above embodiment is as follows: the crushed crystals move to the outlet end of the collection shell 7, the filter screen 15 filters them to remove larger particles, and the heating block 16 heats the filtered crystals to make them re-dissolve into liquid biocarbon source.

[0028] Reference Figure 2One embodiment shown is as follows: the collecting shell 7 is arc-shaped, with its inlet end along the tangential direction of the main stirring shaft 2 and its outlet end along the radial direction of the main stirring shaft 2. In this embodiment, this structural design allows the inlet end of the collecting shell 7 to better utilize the inertia of the fluid to draw the biochar source containing crystals into the collecting shell 7 when it rotates with the main stirring shaft 2. The radial direction of the outlet end facilitates the smooth discharge of the treated biochar source from the collecting shell 7 and also helps to redisperse the treated biochar source within the storage tank 1.

[0029] The implementation principle of the above embodiment is as follows: when the main stirring shaft 2 rotates, the arc-shaped collecting shell 7 can collect crystals more efficiently at the inlet end in the tangential direction, while the outlet end in the radial direction facilitates the return of the processed biocarbon source to the storage tank 1.

[0030] Reference Figure 3 , Figure 5 One embodiment is shown as follows: A drive motor 17 is installed inside the storage tank 1. In this embodiment, the drive motor 17 is fixed inside the storage tank 1 by bolts or other connecting parts. The output end of the drive motor 17 is coaxially and fixedly connected to the main stirring shaft 2, and power transmission is achieved through a coupling or other means, enabling the drive motor 17 to drive the main stirring shaft 2 to rotate. A sliding shaft 18 is movably connected inside the enclosed cavity 4 of the main stirring shaft 2. The sliding shaft 18 and the enclosed cavity 4 are fitted with a clearance fit to ensure that the sliding shaft 18 can slide smoothly within the enclosed cavity 4. An electric telescopic rod 19 is provided at the other end of the main stirring shaft 2. The electric telescopic rod 19 is fixed to the main stirring shaft 2 by bolts or welding. The output end of the electric telescopic rod 19 is fixedly connected to the sliding shaft 18 by bolts or welding. A sliding plug 20 is provided on the sliding shaft 18. The sliding plug 20 is connected to the sliding shaft 18 by welding or integral molding, and the sliding plug 20 is sealed to the inner wall of the enclosed cavity 4 to prevent leakage of the bio-carbon source. Two connecting cavities 5 are respectively provided with compression springs 21. One end of the compression spring 21 is fixed to the inner wall of the connecting cavity 5, and the other end is fixedly connected to the sliding rod 6 on the corresponding side. The connection is achieved by welding or hooking.

[0031] The implementation principle of the above embodiment is as follows: the electric telescopic rod 19 pushes the sliding shaft 18 to slide within the closed cavity 4, and the sliding shaft 18 drives the sliding plug 20 to move, changing the size of the space within the closed cavity 4, thereby changing the pressure within the connecting cavity 5. When the pressure within the connecting cavity 5 increases, the compression spring 21 is compressed, and the sliding rod 6 slides outward within the connecting cavity 5; when the pressure within the connecting cavity 5 decreases, the compression spring 21 extends, and the sliding rod 6 slides inward within the connecting cavity 5, thereby adjusting the position of the collecting housing 7.

[0032] The working principle of this device is as follows: The drive motor 17 starts, and its output drives the main stirring shaft 2 to rotate. The main stirring shaft 2, through a fixed connection, drives the horizontal stirring components 3 on both sides to rotate synchronously. The collection shell 7 moves with the horizontal stirring components 3, and its inlet end is arranged tangentially along the main stirring shaft 2. Utilizing fluid inertia, the bio-carbon source containing crystals enters the collection shell 7 through the collection hopper 8. The filter holes 9 on the collection hopper 8 block impurities, allowing only the crystals to enter. Inside the collection shell 7, the micro motor 14 starts, and its output drives the connected gear 13 to rotate. Due to the meshing of the two gears 13, the first crushing roller 11 and the second crushing roller 12 rotate relative to each other, and the crushing teeth on the rollers crush the crystals. The crushed crystals move towards the outlet end of the collection shell 7, where the staggered filter screen 15 and heating block 16 play their role. The filter screen 15 filters out large particles, and the heating block 16 heats the crystals, causing them to redissolve into bio-carbon source. The electric telescopic rod 19 extends and retracts, pushing the sliding shaft 18 to slide within the closed cavity 4. The sliding shaft 18 drives the sliding plug 20 to change the size of the closed cavity 4, and the pressure in the connecting cavity 5 changes accordingly. When the pressure in the connecting cavity 5 changes, the compression spring 21 pushes the sliding rod 6 to slide within the connecting cavity 5, adjusting the position of the collecting shell 7 radially on the main stirring shaft 2 to accommodate the collection of crystals at different locations.

[0033] The working principle of this device has been explained through the above embodiments. These embodiments only illustrate several implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
