Description

Technical Field

[0001] The utility model belongs to the field of biomass crushing, and specifically relates to a biomass raw material crushing device. Background Art

[0002] Biomass power generation is the power generation using the biomass energy possessed by biomass, which is a kind of renewable energy power generation, including direct combustion power generation of agricultural and forestry waste, gasification power generation of agricultural and forestry waste, waste incineration power generation, landfill gas power generation, and biogas power generation. The crushing device for biomass raw materials belongs to biomass power generation equipment.

[0003] The patent application with the publication number CN218393849U discloses a crushing device for biomass raw materials, including: a feeding mechanism and a crushing mechanism connected to the feeding mechanism; the crushing mechanism includes a group of driving motors penetrating and connecting to the upper end of one side of the feeding mechanism, a screw rod connected to the front output end of the driving motor, a group of shaft seats penetrating and connecting to the upper end of the other side of the feeding mechanism, and a plurality of crushing parts equidistantly threadedly connected to the screw rod. By setting the crushing mechanism, the utility model solves the problems of the existing crushing device that generally a single device can only crush a single type of biomass, with insufficient applicability and inability to meet the requirements. At the same time, the crushing structure is generally a structure design of multiple crushing blocks welded on a ring block, and for the integral structure forming process, the overall replacement cost is high after damage.

[0004] However, the above technology has the following drawbacks when in use:

[0005] As described in paragraph 0040 of the above document, "When using the crushing mechanism, first adjust the distance between multiple crushing parts according to the usage requirements. At this time, apply a rotational force to the appropriate crushing parts. Under the rotation of the thread, until the distance between the crushing parts is in a suitable position. Then, under the external control end, drive the screw rod by one of the driving motors in a group of driving motors. The screw rod is fixedly connected to the output end of the driving motor. At this time, multiple meshing front and rear crushing parts can perform the crushing process on the biomass raw materials." And in combination with the attached Figure 1 It can be seen that since there is no shielding mechanism on the upper side of the crushing parts, it is easy for the biomass raw materials to fall between the crushing parts and the side wall of the feeding box, resulting in waste of the biomass raw materials.

[0006] Therefore, a biomass raw material crushing device is proposed to solve the above drawbacks. Utility Model Content
