Biological granulation filtering and separating device

Abstract

The invention discloses a biological granulation filtering and separating device. The biological granulation filtering and separating device comprises a housing. A feeding opening is formed in the middle of the top of the housing. A support rod is arranged on one side of the inner wall of a bottom plate of the housing. A through hole is formed in the top of the support rod. A fixed rod is movablymounted in the through hole. A sieving device is arranged at the bottom of the fixed rod. Springs are mounted on the side wall, away from the support rod, of the housing. A filtering box is connectedbetween the fixed rod and the springs. The filtering box is located under the feeding opening. A moving device is arranged at the bottom of the filtering box. According to the biological granulation filtering and separating device, pressed biomass shells can be filtered and separated quickly and effectively, and the biomass shells with the appropriate size are obtained; the operation is simple andconvenient, the time can be saved, the production efficiency is improved, and the product quality can be improved greatly; and in conclusion, the device is simple in structure, novel in design and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of filtration and separation devices, in particular to a biological granulation filtration and separation device. Background technique [0002] Biomass pellets are processed by cold-state compaction of pulverized biomass straw, forestry waste and other raw materials by using pressing rollers and ring dies under normal temperature conditions. The density of raw materials is generally 0.1-0.13t / m3, and the particle density after molding is 1.1-1.3t / m3, which is convenient for storage and transportation, and greatly improves the combustion performance of biomass. my country is a big energy-consuming country, so adjusting the energy structure and using biomass energy is an inevitable choice. After the biomass is compressed and molded, its volume is greatly reduced, which makes it easier to transport, store and use, and solves the key problem of large-scale utilization of biomass. Therefore, this technology and ...

Problems solved by technology

[0003] In the Chinese patent whose patent number is CN204208788U, a medical particle filter device is mentioned. When filtering materials, the filtering process can be observed, but in the existing filtering and splitting process, the filtering and separating steps take a long time, and the effect is not good, reducing the The production efficiency of biomass pellets makes the biomass pellets used in packaging and transportation ineffective, which affects product quality
