Description

Technical Field

[0001] The utility model relates to the technical field of biomass material screening equipment, in particular to a biomass particle screening device. Background Art

[0002] Biomass pellets are formed by cold compaction using rollers and ring dies under normal temperature conditions on crushed biomass straw, forestry waste and other raw materials. After the production of biomass pellets is completed, in order to improve the quality of the pellets, screening equipment is usually used to screen the biomass pellets and impurities. The feed port in the existing screening equipment is mostly opened at a fixed position on the upper end of the equipment. For example, the existing application number CN202223327170.X discloses an impurity screening device for biomass pellet production, including a body, grooves are provided on both side walls of the body, telescopic rods are fixedly provided on the top of the two grooves, the lower ends of the two telescopic rods are jointly fixedly connected to the first filter plate, support plates are fixedly provided on both side walls of the body, vibration motors are fixedly provided on the upper ends of the two support plates, and the output ends of the two vibration motors are fixedly connected to the top plate, a hopper is fixedly provided on the lower end of the inner wall of the body, a vibrator is fixedly provided on both sides of the lower end of the hopper, and a fixed seat is fixedly provided on both side walls of the hopper. Based on the above, during the feeding process of biomass pellets, it is very easy to cause the pellets to accumulate below the feed port, affecting the screening effect of biomass pellets and impurities. At the same time, during the long-term use of the screening equipment, it is also very easy to cause the impurities to block the screen, making it difficult to effectively screen the biomass pellets, affecting the working efficiency when screening the biomass pellets. To this end, we propose a biomass pellet screening device. Utility Model Content

[0017] In the above solution, the limiting ring 11 is fixed on the supporting column 12 , and a base 13 is provided at the bottom of the supporting column 12 .

[0018] In the above scheme, the rotary drive mechanism includes a ring gear 15 fixed to the outside of a fixed ring 14. The bottom of the ring gear 15 is meshed with a gear 16, and the side of the gear 16 is connected to a motor 17. By rotatably and tilting the cylinder 1 above the support column 12, the motor 17, gear 16, ring gear 15 and other structures cooperate to drive the cylinder 1 to rotate, causing the material to continuously turn inside the cylinder 1, thereby ensuring continuous contact with the screening mechanism. During this process, the first cylindrical filter 19 and the second cylindrical filter 2 cooperate to filter the material according to particle size, thereby improving the material screening efficiency.

[0019] In the above solution, the motor 17 is electrically connected to the switch 18 .

[0020] In the above scheme, the inner sides of the ends of the cylinder 1, the first cylindrical filter screen 19 and the second cylindrical filter screen 2 are provided with internal threaded portions 21, and the ends of the first material receiving cylinder 22, the second material receiving cylinder 23 and the third material receiving cylinder 24 are provided with external threaded portions that cooperate with the internal threaded portions 21.

[0021] By arranging the first material receiving barrel 22, the second material receiving barrel 23 and the third material receiving barrel 24 which are connected in a spiral manner at the end of the barrel body 1, the materials which have passed the double screening can be automatically classified and collected, thereby achieving the effect of fine screening of the material particles and facilitating the subsequent processing of the collected materials, thereby achieving the purpose of quickly classifying and collecting the particulate materials.

[0022] In the above scheme, a plugging cover 26 is inserted into the feed port 25. When adding materials, the plugging cover 26 is removed, and then the plugging cover 26 is clamped again after the materials are added into the cylinder 1.

[0023] In the above solution, the hair blowing mechanism includes a fan 27 , the air outlet of the fan 27 is connected to a diversion pipe 29 through a hose 28 , the end of the diversion pipe 29 is connected to an air outlet pipe 3 , and the air outlet pipe 3 is connected to a plurality of nozzles 31 .

[0025] Working principle:

[0026] When using this biomass particle screening device, the plug cover 26 is removed, and then the material is added to the cylinder 1. At this time, the gear 16 is driven to rotate under the action of the motor 17, and the gear 16 drives the ring gear 15 to rotate, so that the cylinder 1 continues to rotate in the limit ring 11, so that the material continues to turn over inside the cylinder 1, so that the material can be continuously in contact with the screening mechanism. In this process, the first cylindrical filter 19 and the second cylindrical filter 2 cooperate to filter the material according to the particle size (the mesh diameter of the first cylindrical filter 19 is larger than the mesh diameter of the second cylindrical filter 2). , which improves the screening and processing efficiency of the material. The materials that have been screened enter the first material receiving barrel 22, the second material receiving barrel 23 and the third material receiving barrel 24 at the end of the cylinder 1. In this process, the airflow generated by the fan 27 can be used to blow the biomass material particles from the cylinder 1. On the one hand, it can accelerate the movement rate of the particles, and on the other hand, it can blow the particles up, further increase the contact range between the particles and the screening mechanism, and improve the quality of the screening process. After that, the first material receiving barrel 22, the second material receiving barrel 23 and the third material receiving barrel 24 can be removed to obtain granular materials classified according to size.
