Description

Technical Field

[0001] The present invention relates to the field of biomass charcoal preparation, and particularly relates to a biomass charcoal preparation device with an auxiliary blanking component. Background Art

[0002] As is well known, biomass charcoal is a solid carbon material obtained by pyrolyzing or carbonizing biomass (such as crop residues, wood waste, etc.). Its preparation process can effectively convert biomass into high-value charcoal products, and has broad application potential, such as soil improvement, carbon capture and storage, energy storage, etc.

[0003] For example, the authorized announcement number is CN114106902B, the authorized announcement date is August 2, 2022, and the name is a biomass charcoal preparation device, including a chassis, a processing box, a feeding funnel, and a discharging port. The feeding funnel and the discharging port are both arranged on the chassis. The processing box is arranged inside the chassis and is communicated with the feeding funnel. A filter screen is also arranged on the processing box. It further includes: a set of crushing rollers, symmetrically and movably arranged inside the processing box; power components, having the same number as the crushing rollers, the power components are arranged on the chassis and are connected to the crushing rollers; a discharging pipe, arranged on the chassis and communicated with the discharging port; a drying system, arranged inside the chassis, used for drying the produced materials obtained after crushing; and a driving system...

[0004] Similar to the above application, during the biomass charcoal preparation process, it needs to be crushed. In existing processing equipment, the material adding device is generally installed above the crushing chamber, so that the material "falls into" the crushing chamber by its own rotation. However, biomass charcoal often has different sizes, and during the falling process, the material often accumulates and jams, affecting the processing efficiency. Moreover, this structure with the feeding hopper installed above the crushing chamber makes there be a certain space above the crushing chamber, and this space easily affects the crushing effect.

[0035] The following description is essentially exemplary only and is not intended to limit the present disclosure, its application, and uses. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. Each drawing only schematically shows the concept and principle of the embodiments of the present disclosure, and does not necessarily show the specific dimensions and their ratios of the embodiments of the present disclosure. In a specific part of a specific drawing, the relevant details or structures of the embodiments of the present disclosure may be illustrated in an exaggerated manner. Embodiment

[0036] As Figure 8 - Figure 11As shown: This embodiment provides a technical solution: a biomass carbon preparation device with an auxiliary blanking component, which is applied to the crushing and processing of biomass carbon. It includes a main body housing 1 and a crushing roller 26. Among them, a crushing die 21 is installed inside the main body housing 1. The crushing die 21 adopts a cylindrical structure with one side closed and the other side open. A number of discharge through holes 211 are opened on the surface of the crushing die 21. The crushing roller 26 is installed inside the crushing die 21, and crushing blades 25 are provided on the surface of the crushing roller 26 for crushing the materials in the crushing die 21. A front spacer ring 22 is provided at the outer edge of the open side of the crushing die 21 inside the main body housing 1. Through the front spacer ring 22, the internal space of the main body housing 1 is divided into: a crushing chamber 29 within the internal area range of the crushing die 21, a discharge chamber 28 in the outer area at the edge of the crushing die 21, and a feeding chamber 27 in the outer area on the open side of the crushing die 21. A spiral pusher 20 is provided inside the feeding chamber 27, and the spiral pusher 20 is linked and connected to the crushing roller 26.

[0037] Working principle: When the device is in use, first, the biomass carbon raw materials to be crushed and processed are added to the feeding chamber 27 through a conveying device or a material hoist, and then enter the crushing chamber 29 from the feeding chamber 27. After being crushed by the crushing roller 26, they enter the discharge chamber 28 through the discharge through holes 211 and are discharged.

[0038] It should be noted that: Since the lengths and sizes of the biomass carbon raw materials are different, it is easy to accumulate in the feeding chamber 27 and 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 biomass carbon raw materials in the feeding chamber 27 can smoothly fall into the crushing chamber 29 for crushing and processing, thus ensuring the smooth processing and preparation of biomass carbon. Moreover, the spiral pusher 20 in the feeding chamber 27 is linked and connected to the crushing roller 26, so that the spiral pusher 20 does not require an additional motor control, which not only saves the cost of the equipment, but also enables the spiral pusher 20 and the crushing roller 26 to have a higher synchronization rate.

[0039] This embodiment provides a biomass carbon preparation device with an auxiliary blanking component. Specifically, as Figure 8 - Figure 11 shown, in order to improve the crushing efficiency of the crushing roller 26 on the materials and thus improve 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 die 21, and a triangular plate 24 is provided in the middle of the open side of the crushing die 21. The core turntable 9 and the triangular plate 24 are connected by a driving core shaft 19;

[0040] A plurality of crushing rollers 26 are provided. The plurality of crushing rollers 26 are installed between the triangular plate 24 and the core turntable 9. When the driving 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, and material crushing is carried out in the crushing chamber 29.

[0041] This embodiment provides a biomass carbon preparation device with an auxiliary blanking assembly. Specifically, as Figure 8 - Figure 11 shown, in order to increase the speed of the crushing roller 26 and further improve the crushing efficiency of the crushing roller 26 for the material, in this embodiment, the crushing roller 26 is rotatably installed between the triangular plate 24 and the core turntable 9 through bearings. A planetary gear 23 is installed at one end of the crushing roller 26 located on the open side of the crushing die 21. A stepped opening 210 is provided at the inner wall position of the open side of the crushing die 21, and a toothed ring structure 213 is provided at the inner wall position of the stepped opening 210. The planetary gear 23 is meshed and connected with the toothed 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 toothed ring structure 213, each crushing roller 26 rotates around its own axis, so as to achieve the effect of speed-increasing rotation and further improve the crushing efficiency of the crushing roller 26 for the material.

[0042] This embodiment provides a biomass carbon preparation device with an auxiliary blanking assembly. Specifically, as Figure 4 - Figure 6 and Figure 10 shown, in order to realize the drive control of the crushing roller 26 and ensure that the drive device is not affected by the crushed material, in this embodiment, a front cover 6 is installed at the front part of the main body housing 1. One end of the core turntable 9 extends to the front cover 6, and a drive toothed ring 10 is sleeved and installed outside one end of the front cover 6. A gear cover 12 is installed at the edge of the drive toothed ring 10 inside the front cover 6. A drive motor 11 is installed on the gear cover 12. The output shaft of the drive motor 11 extends into the gear cover 12 and is installed with a drive gear 13. The drive gear 13 is meshed and connected with the drive toothed ring 10. The front shell plate 5 is fixedly installed on the surface of the front cover 6 by bolts or screw threads or snap fasteners, so that the drive structure of the crushing roller 26 is located in a closed space, improving the safety of the device. When the drive motor 11 is running, the drive gear 13 is driven to rotate through the output shaft. Under the meshing action of the drive gear 13 and the drive toothed ring 10, the drive toothed ring 10 drives the core turntable 9 to rotate, so as to realize the drive control of the crushing roller 26.

[0043] This embodiment provides a biomass carbon preparation device with an auxiliary blanking assembly. Specifically, as Figure 9 and Figure 12As shown in the figure, in order to ensure that the material can be smoothly discharged after being crushed by the crushing die 21, in this embodiment, a fixing plate 7 is provided on one side of the main body housing 1 for installing the front cover 6. An eaves plate 212 is provided on the outer edge of the closed side of the crushing die 21. The eaves plate 212 is fixedly installed on the fixing plate 7 by bolts, so that an independent discharge chamber 28 is formed between the eaves plate 212 and the front spacer ring 22 in the area outside the crushing die 21. Such a structural setting enables the material to freely and automatically enter any position of the discharge chamber 28 through the discharge through hole 211 without obstruction after being crushed in the crushing chamber 29, and then automatically fall after entering the discharge chamber 28, facilitating the discharge of the material. Embodiment

[0044] As Figure 7 - Figure 9 shown: In order to improve the efficiency of the material entering the crushing chamber 29 from the feeding chamber 27 and achieve the effect of assisting in the falling of the material, on the basis of Embodiment 1, in this embodiment, a plurality of screw feeders 20 are provided. The plurality of screw feeders 20 are arranged in a circular array centered on the center of the crushing chamber 29. The plurality of screw feeders 20 are installed in a plane perpendicular to the triangular plate 24. The action range of the plurality of screw feeders 20 is located between the edge of the triangular plate 24 and the inner side of the crushing chamber 29. In this way, the rotation of the triangular plate 24 will not block the screw feeder 20 from pushing the material, thereby ensuring its pushing effect. It should be noted that when the triangular plate 24 rotates, although its end position rotates to the axis position of the screw feeder 20, it will block the screw feeder 20 from pushing the material, but with the continuous rotation of the triangular plate 24, it will not cause an impact on the pushing of the material.

[0045] This embodiment provides a biomass carbon preparation device with an auxiliary blanking component. Specifically, as Figure 7 - Figure 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.

[0046] 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.

[0047] This embodiment provides a biochar preparation device with an auxiliary material dropping component, specifically, Figure 7 , Figure 8As shown, in order to facilitate the conveyance of materials into the pulverizing chamber 29, in this embodiment, a guiding plate 16 is installed below the interior of the feeding chamber 27. The guiding plate 16 adopts an arc-shaped structure, and the lowest position of the upper surface of the guiding plate 16 is not lower than the bottom position of the opening of the pulverizing chamber 29. In this way, under the guiding action of the guiding plate 16, the materials can be concentrated towards the middle of the pulverizing chamber 29. And under the pushing of the spiral feeder 20, there will be no dead corners for the materials in the feeding chamber 27, ensuring that all the materials can finally be fed into the pulverizing chamber 29 for pulverizing processing (if the guiding plate 16 is not provided, there will be a feeding dead corner at the bottom of the feeding chamber 27, and part of the materials will remain at the bottom of the feeding chamber 27 during each processing, affecting the processing).

[0048] This embodiment provides a biomass carbon preparation device with an auxiliary blanking assembly. Specifically, as Figure 12 , Figure 13 shown, in order to facilitate the materials to smoothly enter the discharge chamber 28 through the discharge through-hole 211 after being pulverized, in this embodiment, an included angle α is provided between the axial direction of the discharge through-hole 211 and the radial direction of the pulverizing die 21. The value range of the included angle α is 30° ≤ α < 60°, making the discharge through-hole 211 inclined (such as the direction two in Figure 13 ), facing the rotation direction of the pulverizing roller 26 (such as the direction one in Figure 13 ). In this way, the discharge efficiency of the materials after being pulverized can be improved, and when part of the materials is stuck in the discharge through-hole 211, the pulverizing effect of the materials can be improved by the extrusion of the pulverizing roller 26. Specifically, the value of the included angle α is 45°.

[0049] Furthermore, as Figure 1 - Figure 4 shown, a feeding hopper 2 is installed at the top of the main body housing 1. The feeding hopper 2 is communicated with the feeding chamber 27 for feeding materials into the feeding chamber 27. A discharging hopper 3 is installed at the bottom of the main body housing 1. The discharging hopper 3 is communicated with the discharge chamber 28 for discharging materials.

[0050] Furthermore, for the installation and support of the entire device, as Figure 3 shown, an installation bracket 8 is provided at the bottom of the main body housing 1. Through the installation bracket 8, the device can be mounted on a pre-installed equipment bracket. This split-type installation structure can facilitate the transportation of the device.

However, those skilled in the art can understand that without departing from the concept of the present disclosure, various modifications and variations can be made to the above specific embodiments, and various combinations of the technical features and structures proposed in the present disclosure can be made without exceeding the protection scope of the present disclosure.
