Bark shredding machine

Abstract

The invention discloses a bark shredding machine, which is provided with a conveying mechanism and a cut-off device. The bark shredding machine is characterized in that: the conveying mechanism is a rolling and conveying mechanism, and consists of an upper conveying chain (4), a lower conveying chain (3) and a hydraulic cylinder (5), wherein the upper conveying chain (4) of the conveying mechanism is controlled by the hydraulic cylinder (5), can lift freely and can play a role in rolling a material; and the cut-off device consists of a machine shell (9) and a knife roll set (6), wherein 3 to 6 fly knives (8) are distributed on the knife roll and the machine shell is provided with a row of fixed dead knives (7). The bark shredding machine replaces an unordered striking mode by using a mode of combining rolling and cut-off, and has the advantages of uniform and reliable feeding, good cut-off effect and energy conservation; and meanwhile, because the material is cut into fine powder, winding or clasping blockage is not produced during burning.

Description

technical field [0001] The invention relates to a poplar bark chopping device, which belongs to special equipment for processing biomass raw materials, is applied in the field of recycling biomass raw materials, and is one of the necessary equipment for the biomass power generation process. Background technique [0002] The development and utilization of biomass energy is of great significance for enterprises to save energy, reduce consumption, protect the ecological environment, and achieve sustainable development. Although the utilization of biomass energy has broad development prospects, the development of domestic biomass ginseng power generation technology is relatively late, and there is a lack of special equipment for the treatment of various biomass raw materials. Bark crushing equipment generally uses impact straw crushers, and the crushing effect Not ideal, especially not suitable for tough bark such as fresh poplar and eucalyptus. This kind of bark is characteriz...

Although the utilization of biomass energy has broad development prospects, the development of domestic biomass ginseng power generation technology is relatively late, and there is a lack of special equipment for the treatment of various biomass raw materials. Bark crushing equipment generally uses impact straw crushers, and the crushing effect Not ideal, especially for tough bark such as fresh poplar and eucalyptus

This kind of bark is characterized by strong toughness, not easy to break, and easy to break into filaments. After being hit by a crusher, the filaments cannot be broken, forming cotton and hemp-like flocs, which seriously block the process and affect the effect of ginseng.
