[0035] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0036] Example 1

[0037] like Figure 8 - Fig.11As shown: This embodiment provides a technical solution: a biochar preparation device with an auxiliary blanking component, which is used for biochar pulverization processing, and includes a main shell 1 and a pulverizing roller 26, wherein a pulverizing mold 21 is installed inside the main shell 1, and the pulverizing mold 21 adopts a cylindrical structure with one side closed and the other side open. A plurality of discharge through holes 211 are opened on the surface of the pulverizing mold 21, and the pulverizing roller 26 is installed in the pulverizing mold 21. A pulverizing blade 25 is provided on the surface of the pulverizing roller 26 for pulverizing the material in the pulverizing mold 21. A front spacer ring 22 is provided at the outer edge of the open side of the pulverizing mold 21 inside the main shell 1, and the internal space of the main shell 1 is divided into: a pulverizing chamber 29 located in the internal area of ​​the pulverizing mold 21, a discharge chamber 27 located in the outer area of ​​the edge of the pulverizing mold 21, and a feeding chamber 27 located in the outer area of ​​the open side of the pulverizing mold 21, and a spiral pusher 20 is provided inside the feeding chamber 27, and the spiral pusher 20 is linked to the pulverizing roller 26.

[0038] Working principle: When the device is in use, the biomass charcoal raw material to be crushed is first added to the feeding chamber 27 through a conveying device or a material elevator, and then enters the crushing chamber 29 from the feeding chamber 27 to be crushed by the crushing roller 26, and then enters the discharging chamber 28 through the discharging hole 211 and is discharged.

[0039] It should be noted that: since the biochar raw materials are of different lengths and sizes, they are prone to accumulation in the feeding chamber 27 and are difficult to enter the crushing chamber 29. Therefore, a spiral pusher 20 is installed inside the feeding chamber 27. Through the auxiliary feeding of the spiral pusher 20, the biochar raw materials in the feeding chamber 27 can be smoothly dropped into the crushing chamber 29 for crushing processing, thereby ensuring smooth processing and preparation of the biochar. The spiral pusher 20 in the feeding chamber 27 is linked to the crushing roller 26, so that the spiral pusher 20 does not need to be controlled by an additional motor, which not only saves the cost of the equipment, but also enables the synchronization rate of the spiral pusher 20 and the crushing roller 26 to be higher.

[0040] This embodiment provides a biochar preparation device with an auxiliary material dropping component, specifically, Figure 8 - Fig.11 As shown, in order to improve the crushing efficiency of the crushing roller 26 on the material, thereby improving the processing rate of the entire equipment, in this embodiment, a core turntable 9 is rotatably installed in the middle of the closed side of the crushing mold 21, and a triangular plate 24 is provided in the middle of the open side of the crushing mold 21. The core turntable 9 and the triangular plate 24 are connected by an active core shaft 19;

[0041] There are a plurality of crushing rollers 26 installed between the triangular plate 24 and the core turntable 9. When the active core shaft 19 rotates, the triangular plate 24 and the crushing rollers 26 installed between the triangular plate 24 and the core turntable 9 rotate synchronously to crush the material in the crushing chamber 29.

[0042] This embodiment provides a biochar preparation device with an auxiliary material dropping component, specifically, Figure 8 - Fig.11 As shown, in order to increase the speed of the crushing roller 26 and further improve the crushing efficiency of the crushing roller 26 on the material, in this embodiment, the crushing roller 26 is rotatably installed between the triangular plate 24 and the core turntable 9 through a bearing, and a planetary gear 23 is installed at one end of the crushing roller 26 located on the open side of the crushing mold 21, and a step opening 210 is provided on the inner wall of the open side of the crushing mold 21, and a gear ring structure 213 is provided on the inner wall of the step opening 210, and the planetary gear 23 is meshed with the gear ring structure 213. Therefore, when the triangular plate 24 and the core turntable 9 rotate synchronously, under the meshing action of the planetary gear 23 and the gear ring structure 213, each crushing roller 26 rotates about its own axis, thereby achieving the effect of increasing the rotation speed and further improving the crushing efficiency of the crushing roller 26 on the material.

[0043] This embodiment provides a biochar preparation device with an auxiliary material dropping component, specifically, Figure 4 - Figure 6 and Fig.10 As shown, in order to realize the drive control of the crushing roller 26 and ensure that the driving device is not affected by the crushed materials, in this embodiment, a front cover 6 is installed at the front of the main shell 1, one end of the core turntable 9 extends to the front cover 6, and a driving gear ring 10 is sleeved and installed on the outside of one end of the front cover 6, and a gear cover 12 is installed on the edge of the driving gear ring 10 inside the front cover 6, and a driving motor 11 is installed on the gear cover 12, and the output shaft of the driving motor 11 extends into the gear cover 12 and is installed with a driving gear 13, and the driving gear 13 is meshed and connected with the driving gear ring 10, and the surface of the front cover 6 is fixed with a front shell plate 5 by bolt fixing, threaded screwing or snap-fitting, so that the driving structure of the crushing roller 26 is located in a closed space, which improves the safety of the device. When the driving motor 11 is running, the driving gear 13 is driven to rotate by the output shaft, and under the meshing action of the driving gear 13 and the driving gear ring 10, the driving gear ring 10 drives the core turntable 9 to rotate, thereby realizing the drive control of the crushing roller 26.

[0044] This embodiment provides a biochar preparation device with an auxiliary material dropping component, specifically, Fig. 9 and Fig.12As shown, in order to ensure that the material can be discharged smoothly after the crushing mold 21 crushes the material, in this embodiment, a fixing plate 7 is provided on one side of the front cover 6 of the main shell 1, and an eaves plate 212 is provided on the outer edge of the closed side of the crushing mold 21. The eaves plate 212 is fixed to the fixing plate 7 by bolts, so that an independent discharge chamber 27 is formed between the eaves plate 212 and the front spacer ring 22 and located outside the crushing mold 21. Such a structural arrangement enables the material to automatically enter any position of the discharge chamber 27 through the discharge through hole 211 without being blocked after being crushed in the crushing chamber 29, and automatically fall down after entering the discharge chamber 27, so that the discharge is convenient.

[0045] Example 2

[0046] like Figure 7 - Fig. 9 As shown: In order to improve the efficiency of materials entering the crushing chamber 29 from the feeding chamber 27 and achieve the effect of assisting material dropping, on the basis of Example 1, in this embodiment, a plurality of spiral pushers 20 are provided, and the plurality of spiral pushers 20 are distributed in a circular array with the center of the crushing chamber 29, and the plurality of spiral pushers 20 are installed in a plane perpendicular to the triangular plate 24. The action range of the plurality of spiral pushers 20 is located between the edge of the triangular plate 24 and the inner side of the crushing chamber 29, so that the rotation of the triangular plate 24 will not block the spiral pusher 20 from pushing materials, thereby ensuring its pushing effect. It should be noted that when the triangular plate 24 rotates, when its end position rotates to the axial position of the spiral pusher 20, although it will block the spiral pusher 20 from pushing materials, as the triangular plate 24 continues to rotate, it will not affect the pushing of materials.

[0047] This embodiment provides a biochar preparation device with an auxiliary material dropping component, specifically, Figure 7 - Fig. 9As shown, in order to realize the linkage connection between multiple spiral pushers 20 and the crushing roller 26, in this embodiment, a rear partition 14 is installed inside the main shell 1, and the rear partition 14 separates an independent linkage chamber 15 from the inside of the main shell 1. One end of the spiral pusher 20 is rotatably mounted on the rear partition 14 through a bearing, and the shaft of the spiral pusher 20 extends into the linkage chamber 15. The center position between the triangular plate 24 and the core turntable 9 is connected through a core shaft 19, and one end of the core shaft 19 extends into the linkage chamber 15. The end of the axis of the spiral pusher 20 located in the linkage chamber 15 and the end of the core shaft 19 extending into the linkage chamber 15 are both sleeved with a linkage wheel 18. All the linkage wheels with the spiral pushers The interlocking wheel 18 sleeved on the shaft of the device 20 and the interlocking wheel 18 sleeved on the core shaft 19 are connected through the interlocking belt 17. Therefore, when the triangular plate 24 and the core turntable 9 rotate, the crushing roller 26 is driven to rotate and crush the material. Under the transmission action of the interlocking wheel 18 and the interlocking belt 17, all the spiral pushers 20 can start to rotate and feed materials at the same time, so that the device has a high synchronization rate when processing materials and the equipment cost is low. Therefore, the setting of the rear partition 14 not only provides a mounting structure for the spiral pusher 20, but also provides an independent space for the interlocking structure of the spiral pusher 20, thereby achieving the effect of protecting the interlocking structure and preventing the material from affecting the operation of the interlocking structure.

[0048] It should be noted that the linkage between the spiral pushers 20 here does not use a sprocket and a chain belt, because when the spiral pusher 20 is pushing the material, if the material in the crushing chamber 29 is too large, the use of the sprocket and the chain belt linkage will easily lead to excessive pressure on the spiral pusher 20 at this time, causing the spiral pusher 20 to deviate or be damaged, affecting the operation of subsequent equipment, and this problem can be well solved by the linkage wheel 18 and the linkage belt 17. When the material in the crushing chamber 29 is too large, the pressure transmitted from the spiral pusher 20 to the linkage belt 17 in the reverse direction will cause the linkage belt 17 and the linkage wheel 18 to produce "beating". The screw pusher 20 will not continue to push the material, thereby preventing the screw pusher 20 from being deflected or damaged due to continuous excessive force. When the material in the crushing chamber 29 is crushed and the pressure is reduced, the linkage belt 17 and the linkage wheel 18 resume the transmission effect, so that the screw pusher 20 continues to push the material, thereby protecting the equipment. Furthermore, the linkage belt 17 is a wearing part and needs to be replaced regularly. Therefore, the linkage chamber 15 is fixed with the rear shell plate 4 by bolts, threaded engagement, or snap-on engagement. When the rear shell plate 4 is disassembled, the linkage belt 17 can be disassembled and replaced.

[0049] This embodiment provides a biochar preparation device with an auxiliary material dropping component, specifically, Figure 7 , Figure 8As shown, in order to facilitate the transportation of materials into the crushing chamber 29, in this embodiment, a guide plate 16 is installed at the lower part of the feeding chamber 28. The guide plate 16 adopts an arc-shaped structure, and the lowest position of the upper surface of the guide plate 16 is not lower than the bottom position of the opening of the crushing chamber 29. In this way, the materials can be concentrated to the middle of the crushing chamber 29 under the guidance of the guide plate 16, and under the push of the spiral pusher 20, there will be no dead corners in the feeding chamber 28, ensuring that all the materials can eventually be fed into the crushing chamber 29 for crushing processing (if the guide plate 16 is not provided, there will be a dead corner for feeding at the bottom of the feeding chamber 28, and some materials will remain at the bottom of the feeding chamber 28 each time the feeding chamber 28 is processed, affecting the processing).

[0050] This embodiment provides a biochar preparation device with an auxiliary material dropping component, specifically, Fig.12 , Fig.13 As shown, in order to facilitate the material to smoothly pass through the discharge hole 211 into the discharge chamber 28 after being crushed, in this embodiment, an angle α is set between the axial direction of the discharge hole 211 and the radial direction of the crushing mold 21, and the value range of the angle α is 30°≤α<60°, so that the discharge hole 211 is inclined (such as Fig.13 In the direction 2), facing the rotation direction of the crushing roller 26 (such as Fig.13 In the direction 1 in the figure, the discharge efficiency of the material after being crushed can be improved, and when the material is partially stuck in the discharge through hole 211, the crushing effect of the material can be improved by squeezing by the crushing roller 26. Specifically, the value of the angle α is 45°.

[0051] Furthermore, if Figure 1 - Figure 4 As shown, a loading bin 2 is installed on the top of the main shell 1, and the loading bin 2 is connected to the feeding chamber 27 for loading materials into the feeding chamber 27. A lower hopper 3 is installed on the bottom of the main shell 1, and the lower hopper 3 is connected to the discharging chamber 28 for discharging materials.

[0052] Furthermore, for the installation and support of the entire equipment, such as Figure 3 As shown, a mounting bracket 8 is provided at the bottom of the main housing 1, and the device can be mounted on a pre-installed equipment bracket through the mounting bracket 8. This split installation structure can facilitate the transportation of the device.

However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
