Description

Technical Field

[0001] The utility model relates to the technical field of material distribution devices, in particular to a material distribution device of a biomass pellet machine. Background Art

[0002] In the current biomass energy utilization and related industries, the demand for precise screening and sorting of biomass pellets is increasing. Traditional biomass pellet sorting devices often have the problem of unadjustable particle screening range, which limits their flexibility and applicability in different application scenarios. With the continuous advancement of science and technology and the diversification of production needs, the development of a biomass pellet sorting device with adjustable range screening has become an inevitable trend. This new device is designed to meet the specific requirements of different production tasks for particle size, improve the utilization efficiency and production quality of biomass pellets, and adapt to a wider range of applications, such as biomass fuel production, fine chemicals, etc., providing more advanced technical support for promoting the development of the biomass energy industry.

[0003] The existing patent publication number is CN218260963U, which discloses a biomass pellet machine dispensing device with good screening effect, including an installation shell and a dispensing mechanism arranged above the installation shell, the dispensing mechanism including a rotating assembly and a discharging assembly; the rotating assembly includes a first motor, a connecting turntable, a stirring shaft, a feed port and a filter barrel. The utility model pours the biomass particles to be dispensed into the filter barrel at the feed port by setting a stirring shaft, and then quickly stirs the installed stirring shaft inside the filter barrel, and the installed filter barrel is a porous structure. When the stirring shaft quickly stirs the inside of the filter barrel, we can shake the biomass particles inside to a certain extent, so that the internal particles pass through the filter barrel and the filtered particles fall into the collection tank, and the stirring of the stirring shaft facilitates the separation of the mutual connections between the particles, which is convenient for dispensing through the filter barrel.

[0004] The existing biomass pellet machine dividing device has a single dividing method, which mainly relies on the porous structure of the filter barrel for dividing the materials. It can only screen the overall size of the particles, and cannot distinguish other characteristics such as the length and shape of the particles. The dividing method is relatively limited. Especially in terms of distinguishing the length of the particles, the device is completely unable to achieve this, which will bring great inconvenience in some application scenarios that have specific requirements for the length of the particles. For example, in the production process of some biomass fuels, the combustion performance and efficiency of particles of different lengths may vary greatly. If the particles cannot be accurately divided according to their length, it will be difficult to meet production needs. To this end, we propose a dividing device for a biomass pellet machine to solve the above-mentioned problems. Utility Model Content
