Description

Technical Field

[0001] This invention relates to the field of pellet processing, and more particularly to a biomass fuel pellet processing apparatus. Background Technology

[0002] Biomass combustion pellets are block or pellet fuels made from agricultural waste or forestry residues through physical compression. Their core component is biomass energy, which is softened and bound by lignin under high temperature and pressure to form a high-density, low-moisture solid fuel.

[0003] A search revealed Chinese patent application CN110791349B, which discloses a type of biomass fuel pellets and its processing apparatus and method. The biomass fuel pellets are composed of: 15 parts rice husks, 25 parts straw, 10 parts wood scraps, 3 parts corn cobs, 35 parts rice and wheat straw, 5 parts tree roots, 35 parts sawdust, 10 parts sugarcane bagasse, 5 parts cottonseed hulls, 3 parts dehydrating agent, 1 part walnut shell, and 1 part bamboo shavings. The method includes the following steps: Step 1: Input biomass fuel into the fuel processing cylinder; Step 2: Start the reciprocating drive assembly to drive the stirring plate and spiral stirring blades to move up and down reciprocally, and stir the biomass fuel by reciprocating rotation; Step 3: Start the pellet processing drive to drive the two pressure rollers to rotate, and the two pressure rollers, through cooperation with the circular hole seat plate, extrude the biomass fuel from the circular through hole; Step 4: The pellet processing drive drives the cutting blade mechanism to rotate, and the rotating cutting blade mechanism cuts the extruded columnar biomass fuel into pellets; Step 5: The biomass fuel pellets fall into the receiving box for collection.

[0009] Preferably, the granulation assembly includes a connecting sleeve, two extrusion rollers, two scrapers, and two crushing rollers. The connecting sleeve is fixedly sleeved on the outer wall of the rotating rod. The connecting sleeve has a hexagonal cross-section. Support shafts are rotatably connected to both outer walls of the connecting sleeve via bearings. The two extrusion rollers are fixedly sleeved on the outer walls of the two support shafts.

[0010] Preferably, a vibration mechanism is provided on both sides of the bottom of the support plate, and the vibration mechanism cooperates with the granulation mechanism.

[0011] Preferably, the vibration mechanism includes a gear set, a lifting assembly, an impact plate, a fixed shaft, and an impact ball.

[0013] The beneficial effects of this invention are as follows: 1. This invention, through its granulation mechanism and granulation components, processes biomass fuel pellets by loading raw materials onto a granulation plate. Upon activation of the granulation mechanism, a rotating rod drives a connecting sleeve to rotate, and an extrusion roller extrudes the raw materials. After extrusion, the raw materials are discharged through granulation holes. A turntable drives a cutter to rotate synchronously with the rotating rod, cutting the discharged raw materials. The cut pellets fall onto a conveying mechanism for transport. During granulation, as the extrusion roller extrudes the raw materials, some of the raw materials are laid on the granulation plate. A scraper then scrapes the raw materials off the granulation plate. The meshing between gears and a toothed ring causes a crushing roller to rotate, which in turn crushes the scraped raw materials, making them loose and facilitating extrusion roller processing. This prevents the extrusion roller from compressing the raw materials, thus avoiding any impact on biomass fuel pellet processing. 2. The present invention, through the pelletizing mechanism and the vibration mechanism, allows the driving wheel to rotate synchronously with the rotating rod when processing biomass fuel pellets. At this time, the driven wheel drives one of the top blocks to rotate through meshing, while the other top block drives the impact plate to move downward under the cooperation of the lifting end. At this time, the impact ball will impact the top of the fixed seat. The vibration generated during the impact can process the debris adhering to the inner wall of the opening, thereby facilitating the extrusion of the raw material. At the same time, the vibration generated during the impact can process the debris adhering to the pelletizing component, preventing the debris from adhering to the pelletizing component and interfering with the processing of biomass fuel pellets.

During pelleting, as the extrusion roller 26 extrudes the raw material, some of the raw material is laid on the pelletizing plate 18 under the action of the extrusion roller 26. At this time, through... The scraper 27 scrapes the raw material from the pelletizing plate 18. At this time, the meshing between the gear 32 and the toothed ring 31 causes the crushing roller 29 to drive the crushing tooth 30 to rotate.
