Description

Technical Field

[0001] This utility model relates to wood biomass pellet production equipment, and more particularly to a wood biomass pellet raw material crusher with high-efficiency crushing function. Background Technology

[0002] Wood biomass pellets are a type of solid fuel processed from wood or wood fiber materials. They offer advantages such as high calorific value, low moisture content, and environmental friendliness, and are widely used in heating, power generation, and industrial boilers. The raw materials for wood biomass pellets mainly include: sawdust, wood chips, branches, bark, wood processing waste, straw, fruit shells (such as coconut shells and walnut shells), bagasse, timber from trees specifically planted for biomass energy such as willow, poplar, and eucalyptus, construction waste, and discarded furniture (after removing glue, paint, and other contaminants).

[0003] The production of wood biomass pellets first requires crushing the raw materials. Currently, most wood biomass pellet crushers are prone to problems during crushing, such as raw materials getting stuck between the two crushing rollers, which leads to a decrease in crushing efficiency over time. Therefore, this invention proposes a wood biomass pellet crusher with high-efficiency crushing function to overcome the shortcomings of the existing technology. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a wood biomass pellet raw material crusher with high-efficiency crushing function. By setting an anti-clogging mechanism inside the casing on one side of the multi-stage crushing mechanism, the anti-clogging mechanism, composed of a rectangular air trough, an L-shaped air outlet pipe, and an air inlet pipe, can meet the requirement of high-pressure blowing between the two first crushing rollers and the two second crushing rollers of the multi-stage crushing mechanism after movement, blowing the raw material blocked between the two first crushing rollers and the two second crushing rollers downward, thereby avoiding the problem of crushing efficiency affected by clogging.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The rectangular air duct is slidably connected to the through groove. A connecting plate is provided on the outer wall of the outer end of the rectangular air duct located outside the casing. The output end of the movement control cylinder is connected to the connecting plate. An L-shaped outlet pipe is provided at the inner end of the rectangular air duct located inside the casing. Multiple sets of L-shaped outlet pipes are provided. An inlet pipe is provided inside the outer end of the rectangular air duct located outside the casing, and one end of the inlet pipe extends outward from the outer side of the rectangular air duct.

[0007] A further improvement is that the multi-stage crushing mechanism comprises two first crushing rollers and two second crushing rollers. The two first crushing rollers are rotatably disposed above the inside of the machine casing, and the two second crushing rollers are rotatably disposed below the two first crushing rollers. The crushing teeth of the two first crushing rollers are engaged, and the crushing teeth of the two second crushing rollers are engaged.

[0008] A further improvement is that a first drive motor and a second drive motor are provided on the outer wall of the housing, the two first crushing rollers are driven by the first drive motor, and the two second crushing rollers are driven by the second drive motor.

[0011] A further improvement is that baffles are provided at both ends of the base plate and the upright plate.

[0012] The beneficial effects of this utility model are as follows: This utility model sets an anti-blocking mechanism inside the casing on one side of the multi-stage crushing mechanism. The anti-blocking mechanism, which consists of a rectangular air trough, an L-shaped air outlet pipe and an air inlet pipe, can meet the requirement of high-pressure blowing between the two first crushing rollers and between the two second crushing rollers of the multi-stage crushing mechanism after movement, blowing the raw material that is blocked between the two first crushing rollers and between the two second crushing rollers downward, thereby avoiding the problem of crushing efficiency affected by blockage.

[0013] This invention features a protective feeding mechanism inside the feeding box. Raw materials are fed onto an L-shaped seat formed by the bottom plate and the vertical plate. The main shaft is then driven to rotate, causing the raw materials on the L-shaped seat to be flipped into the machine casing for crushing. The bottom plate and the vertical plate can alternately block the feeding port during the feeding process, preventing the raw materials from splashing out of the feeding port during crushing and thus preventing material loss.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1-2 As shown in the figure, this embodiment proposes a wood biomass pellet raw material crusher with high-efficiency crushing function, including a casing 1, a multi-stage crushing mechanism, an anti-clogging mechanism, and a protective feeding mechanism. The multi-stage crushing mechanism is located inside the casing 1. A feeding box 2 is located on one side of the top of the casing 1. The feeding box 2 contains a protective feeding mechanism. An anti-clogging mechanism is located inside the casing 1 on one side of the multi-stage crushing mechanism. A through groove 3 is provided on one side wall of the casing 1. A movement control cylinder 4 is provided on the side wall of the feeding box 2. The anti-clogging mechanism... The plugging mechanism includes a rectangular air duct 5, an L-shaped air outlet pipe 6, and an air inlet pipe 7. The rectangular air duct 5 is slidably connected to the through groove 3. A connecting plate 8 is provided on the outer wall of one end of the rectangular air duct 5 located on the outside of the housing 1. The output end of the moving control cylinder 4 is connected to the connecting plate 8. An L-shaped air outlet pipe 6 is provided at one end of the rectangular air duct 5 located inside the housing 1. Multiple sets of L-shaped air outlet pipes 6 are provided. An air inlet pipe 7 is provided inside one end of the rectangular air duct 5 located on the outside of the housing 1. One end of the air inlet pipe 7 extends out of the outer side of the rectangular air duct 5.

[0019] When the crusher of this utility model is working, the raw material is transferred into the machine casing 1 by the protective feeding mechanism. Then the raw material is crushed in multiple stages by the multi-stage crushing mechanism and finally discharged from the bottom of the machine casing 1. This process can be periodically controlled by the moving control cylinder 4 to move the rectangular air channel 5 into the machine casing 1, so that the L-shaped air outlet pipe 6 at one end of the rectangular air channel 5 moves to the crushing area of ​​the multi-stage crushing mechanism and then blows downward to avoid the raw material from clogging and affecting the crushing efficiency.

[0020] The multi-stage crushing mechanism comprises two first crushing rollers 9 and two second crushing rollers 10. The two first crushing rollers 9 are rotatably disposed above the inside of the housing 1, and the two second crushing rollers 10 are rotatably disposed below the two first crushing rollers 9. The crushing teeth of the two first crushing rollers 9 and the two second crushing rollers 10 are engaged. A first drive motor 11 and a second drive motor 12 are provided on the outer wall of the housing 1. The two first crushing rollers 9 are driven by the first drive motor 11, and the two second crushing rollers 10 are driven by the second drive motor 12. In this invention, the two crushing rollers driven by the same motor move in opposite directions, thereby crushing the raw material. The raw material undergoes first-stage crushing when it enters the crushing zone of the two first crushing rollers 9, and second-stage crushing when it passes through the crushing zone of the two second crushing rollers 10. This two-stage crushing improves crushing efficiency.

[0021] The protective feeding mechanism includes a main shaft 13, a base plate 14, and a vertical plate 15. The feeding box 2 has a feeding port 16, inside which the main shaft 13 is rotatably mounted. The main shaft 13 is driven by a tilting motor 17. The base plate 14 is mounted on the main shaft 13, and a vertical plate 15 is located on one side of the top of the base plate 14. The top of the base plate 14 is a ramp mechanism, and the vertical plate 15 has a right-angled triangular cross-section. Baffles 18 are located at both ends of the base plate 14 and the vertical plate 15. During protective feeding, the raw material is placed onto the base plate 14, and then the main shaft 13 is rotated by driving the tilting motor 17, causing the base plate 14 to tilt. Simultaneously, the vertical plate 15 connected to the base plate 14 tilts, and the raw material quickly slides down the inclined surfaces of the base plate 14 and the vertical plate 15, falling into the crushing zones of the two first crushing rollers 9 for crushing.

[0022] This invention features an anti-clogging mechanism inside the casing 1 on one side of the multi-stage crushing mechanism. This mechanism, composed of a rectangular air duct 5, an L-shaped outlet pipe 6, and an inlet pipe 7, allows for high-pressure blowing between the two first crushing rollers 9 and the two second crushing rollers 10 of the multi-stage crushing mechanism after movement. This blows downwards the material blocking the area between the two first crushing rollers 9 and the two second crushing rollers 10, thus avoiding the impact of clogging on crushing efficiency. Furthermore, this invention includes a protective feeding mechanism inside the feed box 2. The raw material is fed onto the L-shaped seat formed by the bottom plate 14 and the vertical plate 15. The main shaft is then driven to rotate, turning the material from the L-shaped seat into the casing 1 for crushing. During the feeding process, the bottom plate 14 and the vertical plate 15 alternately block the feed inlet 16, preventing splashed material from exiting through the feed inlet 16 and thus preventing material loss.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
