Description

Technical Field

[0001] The utility model relates to the technical field of bio-based raw material processing, in particular to a bio-based raw material crushing device. Background Art

[0002] Bio-based raw materials refer to raw materials derived from biomass resources, including plants, animals, microorganisms, etc. Bio-based raw materials are widely used in chemical industry, materials science, energy and other fields, and can be used to produce bioplastics, biofuels, biofibers and other products. The use of bio-based raw materials helps reduce dependence on fossil resources, reduce environmental pollution and promote sustainable development.

[0003] Existing bio-based raw material crushing devices usually use a mutual collision and extrusion method to complete the crushing of bio-based raw materials. However, existing bio-based raw material crushing devices usually have certain dead angles, which result in some bio-based raw materials being unable to contact the crushing device, thereby reducing the efficiency of the crushing device in crushing the bio-based raw materials, and at the same time affecting the crushing effect of the bio-based raw materials, and failing to meet the demand for uniform crushing of the bio-based raw materials. Based on these problems, Chinese patent CN220634574U discloses a bio-based raw material crushing device, which uses a crushing mechanism component to achieve contact with the screen barrel through a rotation adjustment combined with a telescopic adjustment method to complete the crushing of the bio-based raw materials, thereby facilitating the uniform crushing of the bio-based raw materials by the staff and ensuring the crushing effect of the bio-based raw materials by the staff. At the same time, it prevents some bio-based raw materials from being unable to contact the crushing device, thereby improving the quality of the overall device in crushing the bio-based raw materials and ensuring the effect of the subsequent use of the bio-based raw materials.

[0004] First, there are still dead corners in the screen barrel of the crushing device, such as the area between the turntable and the screen barrel. Bio-based raw materials accumulate in this area, and some areas are also dead corners for the rotation of the crushing plate, making it impossible to completely crush the bio-based raw materials. Secondly, the rotating crushing plate can only scrape off the bio-based raw materials accumulated and attached to the inner wall of the screen barrel, and cannot play a good crushing role.
