Description

Technical Field

[0001] The utility model provides a biomass particle screening device, which relates to the technical field of biomass particle screening. Background Art

[0002] Biomass pellets are made by cold-forming and compacting crushed biomass straw, forestry waste and other raw materials using rollers and ring dies at room temperature. They are convenient for storage and transportation, and greatly improve the combustion performance of biomass. They are often used as feed for livestock in large farms, for civil heating and living energy, as fuel for industrial boilers and kilns, and as fuel for gasification power generation and thermal power generation.

[0003] The patent with the patent authorization announcement number CN220991732U discloses a biomass fuel particle screening and grading device. The patent adds biomass fuel particles into a hopper, and the biomass fuel particles flow from the hopper to the top screen in the top screen frame. At the same time, the motor drives the rotating shaft to rotate through the belt drive, causing the eccentric wheel to rotate synchronously. The wheel rim shakes along the outer edge trajectory generated by the rotation of the eccentric wheel. The wheel rim pushes and pulls the power rod and drives the support column to swing through the shaft rod, thereby causing the front end of the multi-stage screen to swing, so as to screen and grade the biomass fuel through each screen. However, the screening and grading device provided by this patent still has shortcomings during actual use. The device directly lowers the biomass fuel particles in the hopper to flow onto the top screen. When the material unloading speed is fast, it is easy for the biomass particles to accumulate on the top screen, causing material accumulation and screening difficulties, and it is also easy for the material to fall from the top screen to the ground.

[0004] Therefore, it is necessary to provide a biomass particle screening device with uniform feeding. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: A biomass particle screening device, see Figures 1-4As shown, it includes a base 1, a guide plate I2, a guide plate II3, a mounting frame 4, a collecting frame I5, a collecting frame II6, a placement frame 7, a collecting frame III8, a dual-axis motor 9, an eccentric wheel 901, a connecting rod 10, a fixed block 11, a guide rod 12, a support plate I13 and a screen plate 14. The base 1 is provided with a guide plate I2 for guiding biomass particles by bolt connection, and a guide plate II3 is fixedly connected to one side of the guide plate I2 by welding. A mounting frame 4 is mounted on one side of the base 1 by bolt connection, and a collecting frame I5 and a collecting frame II6 for classifying and collecting biomass particles are arranged in a transverse sliding manner in the mounting frame 4. A placement frame 7 is mounted on the other side of the base 1 by bolt connection, and a collecting frame III8 for collecting fine biomass particles is arranged in a transverse sliding manner in the placement frame 7. Two fixing blocks 11 are mounted on both sides of the base 1 and the screen plate 14 by bolt connection, and each fixing block 11 is welded. The guide rod 12 is fixedly connected in a manner, and a support plate I 13 is slidingly provided on the guide rod 12 on the fixed block 11 on the base 1 and the screen plate 14. A plurality of first sieve holes 15 and second sieve holes 16 are provided on the screen plate 14. The aperture of the first sieve hole 15 is smaller than the aperture of the second sieve hole 16. The first sieve hole 15 is located directly above the guide plate II 3, and the second sieve hole 16 is located directly above the guide plate I 2. A dual-axis motor 9 is installed on the base 1 by means of bolts, and an eccentric wheel 901 is fixedly connected to the output shafts on both sides of the dual-axis motor 9 by means of a key connection. The two eccentric wheels 901 and the two sides of the screen plate 14 are rotatably connected with a connecting rod 10, which also includes a support rod 17, a mounting seat 18 and a swing blanking assembly. The support rod 17 is installed on the placement frame 7 by means of bolts, and a mounting seat 18 is installed on the support rod 17 by welding. A swing blanking assembly for uniform blanking is provided on the mounting seat 18.

[0025] See Figure 4 As shown, the swing blanking assembly includes a support column I 19 fixedly connected to the mounting seat 18 by welding, a servo motor 20 is installed on the support column I 19 by bolt connection, a rotating disk 21 is fixedly connected to the output shaft of the servo motor 20 by key connection, a connecting rod 22 is fixedly connected to the eccentric part of the rotating disk 21 by welding, a traction frame 23 is hingedly connected to the connecting rod 22, a support plate II 24 is rotatably provided on the support column I 19, a support column II 25 is rotatably provided on the support plate II 24, the traction frame 23 is rotatably connected to the support column II 25, and a blanking hopper 26 is installed on the support column II 25 by welding.

[0026] When biomass particles need to be screened, the biomass particles are poured into the lower hopper 26, and then the servo motor 20 is started to drive the rotating disk 21 to rotate, so that the rotating disk 21 drives the traction frame 23 to make a circular motion through the connecting rod 22, and the traction frame 23 drives the support column II 25 to rotate on the support plate II 24. At the same time, the support column II 25 on the traction frame 23 swings up and down, so that the biomass particles are discharged with the swing of the lower hopper 26, so that the biomass particles are evenly sprinkled on the screen plate 14. At this time, the dual-axis motor 9 is started at the same time to drive the eccentric wheels 901 on both sides to rotate, and the eccentric wheels 901 pull the screen plate 14 to move through the connecting rod 10. At this time, the screen plate 14 passes through the guide rod on the fixed block 11. 12 makes the support plate I13 swing, and the support plate I13 slides back and forth on the guide rod 12, causing the screen plate 14 to vibrate, so that smaller biomass particles fall from the first sieve hole 15 onto the guide plate II3 and roll into the collection frame III8 for collection. Medium-sized biomass particles fall from the second sieve hole 16 onto the guide plate I2 and roll into the collection frame I5 for collection. Larger biomass particles roll from the guide plate I2 into the collection frame II6 for collection. By sliding and pulling the collection frame III8 out of the placement frame 7, and sliding and pulling the collection frame I5 and the collection frame II6 out of the installation frame 4, biomass particles of different sizes can be packaged and classified for application in different fields.

[0027] Example 2: Based on Example 1, refer to Figure 5 As shown, it also includes electric slide rails 27 symmetrically installed on both sides of the screen plate 14 by bolt connection, and electric sliders 28 are slidably provided on the two electric slide rails 27. The electric sliders 28 on both sides are jointly installed with scrapers 29 for scraping off biomass particles blocking the first screen hole 15 and the second screen hole 16 by bolt connection.

[0028] When the two ends of a single biomass particle are of different sizes, the biomass particle will be stuck in the first sieve hole 15 or the second sieve hole 16, making screening difficult. At this time, the material is stopped and the electric slide rail 27 is started to make the electric slider 28 drive the scraper 29 to slide. The scraper 29 cuts off the biomass particles stuck in the first sieve hole 15 and the second sieve hole 16 on the guide plate I2, so that the biomass particles fall, avoiding difficulties in screening the biomass particles.

[0029] See Figure 6 As shown, it also includes a collecting box 30 installed on the side of the placement frame 7 by means of bolt connection, a dust collecting frame 31 for collecting dust and impurities is provided in a horizontally sliding manner in the collecting box 30, an air intake channel 32 is fixed to the collecting box 30 by welding, and a mounting plate 33 is installed on the air intake channel 32 by means of bolt connection, two dust suction fans 34 are rotatably provided on the mounting plate 33, and a guardrail 35 is installed on the side of the mounting plate 33 by means of bolt connection.

[0030] When smaller biomass particles are sieved through the first sieve hole 15, fine impurities and dust are also likely to follow the biomass particles and roll from the guide plate II3 into the collection frame III8. At this time, the dust suction fan 34 is started to suck the dust and impurities into the air inlet channel 32 and gather and collect in the dust collecting frame 31. The biomass particles are intercepted by the guardrail 35 to prevent them from being sucked in. The dust collecting frame 31 is slid and pulled out to the outside of the collection box 30 to remove the collected dust and impurities.

[0031] See Figure 2 、 Figure 4 and Figure 6 As shown, a limit plate 36 is rotatably provided on one side of the placement frame 7; an elastic member 37 is wound around each guide rod 12; and a cover plate 38 is provided on the top of the lower hopper 26.

[0032] The collecting frame III8 is limited by the limiting plate 36 to prevent the collecting frame III8 from sliding out due to the vibration generated when the device is screening the biomass particles. When the collecting frame III8 needs to be slid and pulled out from the placement frame 7, the limiting plate 36 is rotated to a certain angle to disengage the limiting plate 36 from the limit on the collecting frame III8, and the collecting frame III8 can be slid and pulled out from the placement frame 7; the elastic member 37 pushes the supporting plate I13 close to the fixed block 11, so that the supporting plate I13 supports the screening plate 14 more stably and prevents the screening plate 14 from shaking easily; the cover plate 38 is used to prevent impurities from falling into the lower hopper 26, thereby preventing dust and impurities from mixing into the biomass particles.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
