Description

Technical Field

[0002] Biomass pellets are a type of granular fuel made from biomass materials such as agricultural and forestry waste through processes such as crushing, mixing, and extrusion. These biomass materials usually include wood, crop straw, etc. When processing biomass pellets, the crushing, drying, and mixing of raw materials will generate a large amount of dust. Therefore, a dust removal device is required to remove the dust generated during the crushing process.

[0003] A Chinese patent with announcement number CN211159141U discloses a dust reduction device for biomass pellet fuel processing, which relates to the field of biomass pellet fuel processing. In view of the problem that the existing raw materials of biomass pellet fuel are prone to air pollution during processing, the following solution is proposed, which includes a rotating base, a lifting platform is fixedly installed at the middle position of the top of the rotating base, and a dust removal pipe is welded to the top of the lifting platform, a dust collecting box and a liquid collecting box are welded to the top of the rotating base, and the dust collecting box and the liquid collecting box are respectively located on both sides of the lifting platform; the utility model has a novel structure, and the device can effectively reduce dust and purify the air within different ranges, and can perform dust removal operations on the filter plate at any time, thereby improving the dust reduction efficiency of the device.

[0004] In the existing biomass pellet processing dust removal device, during the material crushing process, although a dust removal device is used for dust removal, dust will still overflow from the feed port. Moreover, the dust suction port of the dust removal device is far away from the feed port, and the dust overflowing from the feed port cannot be sucked away in a timely and effective manner, thereby reducing the dust removal effect and affecting the air environment of the working surface. Therefore, a biomass pellet processing dust reduction device is proposed to address the above problems. Utility Model Content
