Description

Technical Field

[0001] The utility model relates to the technical field of material processing equipment, in particular to a crushing and filtering device. Background Art

[0002] At present, with the increasing demand for renewable energy and environmentally friendly materials, the utilization of biomass resources has received widespread attention. Biomass materials, such as agricultural waste, forestry residues, energy crops, etc., have great potential and can be converted into biofuels, chemicals, building materials and other products. However, in the pretreatment process of biomass, a crushing and filtering device is needed to achieve the pretreatment of biomass fuel.

[0003] After searching, the Chinese patent application number 202122068593.3 discloses a new type of biomass crushing device with high crushing efficiency, including an outer shell, a crushing mechanism, an active feeding mechanism and a sorting mechanism. An active feeding mechanism is arranged at the feed port of the outer shell, and the external biomass is fed into the outer shell for crushing through the active feeding mechanism. The bottom of the crushing mechanism is the sorting mechanism, and the crushed biomass is sorted by the sorting mechanism. The small-particle biomass after sorting comes out through the discharge port, and the large-particle biomass is returned to the crushing mechanism for re-crushing; the biomass is fed into the crushing device by active feeding, and the biomass is squeezed toward the crushing roller by the feeding mechanism.

[0004] The above patents have the following deficiencies: 1. Since the sizes of biomass particles after crushing are different, larger or clumping materials may block the sieve holes of the sorting mechanism, which will not only reduce the screening efficiency, but also may cause uneven particle size distribution of the screened products, affecting the quality and stability of subsequent processing; 2. When adding biomass raw materials, if too much material is added at one time, the crushing mechanism will not be able to process the biomass in time, which will lead to an incomplete crushing process, thereby affecting the efficiency of the entire processing flow.

[0005] Therefore, a crushing and filtering device is urgently needed to solve the above problems. Utility Model Content
