Description

Technical Field

[0001] This utility model relates to the field of fuel crushing technology, and in particular to a biomass pellet fuel feedstock crushing and impurity removal device. Background Technology

[0002] Biomass pellet fuel, as a renewable energy source, primarily uses agricultural waste such as rice husks, straw, and sawdust as raw materials. Crushing and removing impurities from these materials is a crucial step in the production process, directly impacting pellet quality and combustion efficiency. Currently, common crushing and impurity removal devices are typically equipped with filter screens to separate impurities from usable materials during the crushing process. However, the filters in existing devices are mostly fixed installations, requiring the disassembly of multiple connecting parts for cleaning and maintenance. This is cumbersome, time-consuming, and labor-intensive, severely impacting production efficiency. In addition, after prolonged operation, the crushing mechanism is prone to accumulating debris. If not cleaned in time, this not only reduces crushing efficiency but may also cause equipment failure. Therefore, there is an urgent need for a biomass pellet fuel feedstock crushing and impurity removal device that is structurally sound, easy to clean and maintain, and capable of continuous and efficient operation. To address this, we propose a biomass pellet fuel feedstock crushing and impurity removal device to solve the aforementioned problems. Utility Model Content

The top of the guide seat is inclined downward from the center to both sides, and the two sides of the guide seat correspond to the feeding ports.

[0008] Preferably, a crushing mechanism is installed inside the rectangular frame, and the crushing mechanism includes a crushing shaft, a motor, a movable rod, and gears. Two sets of crushing shafts and two sets of movable rods are provided. The front and rear ends of the two sets of movable rods are connected to the bearings on the inner wall of the rectangular frame. One end of one set of movable rods is fixedly connected to the port of the motor. Two sets of gears are provided, and the two sets of gears are symmetrically fixedly sleeved on the surface of the movable rods and mesh with each other.

[0009] Preferably, two sets of third guide plates are provided above the two sets of crushing shafts, and the two sets of third guide plates are respectively fixed to the inner walls of the two sides of the rectangular frame.

[0020] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the rectangular frame 1 has symmetrical feeding ports on both sides at the bottom. The inner bottom of the rectangular frame 1 is fixedly installed with a guide seat 12, and the top of the guide seat 12 is inclined downward from the center to both sides. The two sides of the guide seat 12 correspond to the feeding ports, which facilitates the discharge of the crushed raw materials during use.

[0021] Furthermore, refer to Figure 4 It can be seen that a crushing mechanism is installed inside the rectangular frame 1, and the crushing mechanism includes a crushing shaft 11, a motor 13, a movable rod 14, and gears 15. There are two sets of crushing shafts 11 and two sets of movable rods 14. The front and rear ends of the two sets of movable rods 14 are connected to the bearings on the inner wall of the rectangular frame 1. One end of one set of movable rods 14 is fixedly connected to the port of the motor 13. There are two sets of gears 15. The two sets of gears 15 are symmetrically fixedly sleeved on the surface of the movable rods 14 and mesh with each other. During use, the meshing of the gears 15 drives the two sets of crushing shafts 11 to rotate in opposite directions, which facilitates the crushing operation.

[0022] Furthermore, refer to Figure 4 It can be seen that two sets of third guide plates 10 are set above the two sets of crushing shafts 11. The two sets of third guide plates 10 are fixed to the inner walls of the two sides of the rectangular frame 1 respectively. During use, the third guide plates 10 can play a guiding role, so that the rice husks are concentrated between the two sets of crushing shafts 11 and the crushing is assisted.

[0023] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a support arm 16 is fixedly installed at the bottom of the third guide plate 10, and a movable sleeve 17 is fixedly installed at the bottom of the support arm 16. A guide rod 18 is inserted inside the movable sleeve 17, and a scraper 20 is fixed at one end of the guide rod 18. Brushes are evenly arranged on the side of the scraper 20 that is in contact with the crushing shaft 11, which serves to clean the outer wall of the crushing shaft 11 during use.

[0024] Furthermore, refer to Figure 3 and Figure 4 It can be seen that a spring 19 is sleeved on the surface of the guide rod 18, and one end of the spring 19 is fixedly connected to the side wall of the scraper 20, and the other end of the spring 19 is fixedly connected to the side wall of the movable sleeve 17. During use, the spring 19 itself can push the scraper 20 to always be in contact with the side wall of the crushing shaft 11, so as to achieve the cleaning function.

[0025] Working principle: When using this utility model, according to the appendix Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 and attached Figure 5As shown, first, the motor 13 is powered on. The output end of the motor 13 rotates, driving the movable rod 14 to rotate. The movable rod 14 rotates simultaneously through the meshing of the gear 15, which facilitates the rotation of the two sets of crushing shafts 11. After starting, the rice husk bag containing rice husks is placed into the inner top of the rectangular frame 1 and opened. It is limited by the support frame 3 and the support rod 4. At this time, the rice husks enter the interior of the rectangular frame 1 and are filtered by the filter plate 6. The filtered rice husks are guided by the filter plate 6 into the surface of the third guide plate 10 and then guided by the third guide plate 10 into the space between the crushing shafts 11. The crushing is achieved by the crushing shafts 11. The crushed rice husk raw material is guided out through the guide seat 12, while the dust filtered out of the rice husks enters the interior of the collection tank 5 and is guided out through the second guide plate 9. When the crushing shaft 11 rotates, it can come into contact with the surface of the scraper 20, which facilitates cleaning and prevents a large amount of debris from adhering to the crushing shaft 11. After the work is completed, the staff manually pulls the filter plate 6 outward. The top of the filter plate 6 comes into contact with the brush to achieve cleaning. Then the filter plate 6 is reinserted and fixed by the magnetic strip 8. The operation is complete. The above is the complete working principle of this utility model.
