Biomass materials, which are biomass materials mainly including plant materials or plant recycled materials, and biomass products with a certain particle size can be obtained by granulating the biomass materials as raw materials, in order to screen the large and small particles of the biomass products, a product classification device for processing the biomass materials is provided, as shown in fig. 1-14, and comprises a first screening cylinder 110 and a second screening cylinder 120, wherein the number of the second screening cylinders 120 is multiple, as shown in fig. 2, and the number of the second screening cylinders 120 is two, so that products in the first screening cylinder 110 can be separated when the first screening cylinder 110 inclines to any side. As shown in fig. 2 and 3, the first sieving cylinder 110 and the second sieving cylinder 120 can both rotate around a first axis, the first axis is an axis of the first sieving cylinder 110, the first sieving cylinder 110 and the second sieving cylinder 120 are coaxially arranged, the first sieving cylinder 110 and the second sieving cylinder 120 have the same outer diameter, two ends of the two second sieving cylinders 120 are provided with end cover parts 600, the end cover parts 600 comprise a left end cover 610 and a right end cover 620, the left end cover 610 is rotationally connected with the second sieving cylinder 120 at the left end, the right end cover 620 is rotationally connected with the second sieving cylinder 120 at the right end, a sieving motor 640 is arranged at the outer part of the right end cover 620, and an output shaft of the sieving motor 640 is fixedly connected with the center of the end part of the second sieving cylinder 120, so that the second sieving cylinder 120 is driven to rotate by the sieving motor 640.

As shown in fig. 3 and 6, a blocking assembly 200 is disposed between the first and second sieving barrels 110 and 120, and the blocking assembly 200 has a first region and a second region, and the first region is a region near the edge of the blocking assembly 200 and the second region is a region near the center of the blocking assembly 200 in the present utility model. The barrier assembly 200 has a semi-screening state and a fully screening state, and when the barrier assembly 200 is in the semi-screening state, the second region communicates with the first screen drum 110 and the second screen drum 120, at which time the central region of the barrier assembly 200 is capable of allowing product to pass, i.e. enabling product to flow from the first screen drum 110 to the second screen drum 120. When the blocking assembly 200 is in the fully shielded condition, the second region isolates the first screen cylinder 110 from the second screen cylinder 120, and the central region of the blocking assembly 200 no longer allows product to pass through, i.e., product particles within the second screen cylinder 120 cannot flow back into the first screen cylinder 110.

As shown in fig. 2, 3 and 14, the second sieving cylinder 120 is externally provided with a height adjusting assembly 400, the height adjusting assembly 400 is used for adjusting the included angle between the second sieving cylinder 120 and the horizontal plane, the inclination change of the first sieving cylinder 110 and the second sieving cylinder 120 is an essential technical feature for separating large particle products from the first sieving cylinder 110, when the first sieving cylinder 110 and the second sieving cylinder 120 are inclined, the height of the products on one side of the downward inclination is increased, at this time, the large particle products on the upper layer of the mixed products can contact the blocking assembly 200, and at the same time, after the first sieving cylinder 110 and the second sieving cylinder 120 are inclined, the products can be forced to move to the position of the blocking assembly 200 on the higher side of the product height, so that the large particle products can be separated from the mixed products, and when the first sieving cylinder 110 and the second sieving cylinder 120 change the inclination direction, the large particle products on the upper layer of the first sieving cylinder 110 move to the blocking assembly 200 on the other side, and the large particle products are separated into the corresponding second sieving cylinder 120.

As shown in fig. 14, for the mixed product to be layered inside the first sieving cylinder 110, the large-sized product is located at the upper layer, and the small-sized product is located at the lower layer, it is necessary to explain that this phenomenon is a physical phenomenon generated by shaking objects with different sizes in one container, which is called the brazil effect, and is also a granulation principle of the disk granulator, and the layering phenomenon of the particles occurs during the rotation of the first sieving cylinder 110 and the second sieving cylinder 120 when the first sieving cylinder 110 and the second sieving cylinder 120 are in the horizontal state.

In one embodiment, as shown in fig. 6 and 10, the blocking assembly 200 includes two fixed screens 220, the fixed screens 220 having a first communication hole in a central region having a solid structure in an edge region for satisfying the passing of large-sized products, and the edge region being capable of preventing the passing of large-sized products as well as small-sized products.

The iris mechanism 211 is an implementation manner of a proportional adjusting element, and in other embodiments, other conventional technical means in the art may be adopted to change the area of the first area, for example, an electric telescopic rod and a foldable baffle are arranged at equal intervals in the circumferential direction of the fixed screen 220, the folded end of the baffle is driven by the electric telescopic rod to move to change the area of the first area, when the area of the first area needs to be reduced, the folded end of the baffle is driven by the electric telescopic rod to extend outwards, and at the moment, the area where the first communication hole is located is shielded by the baffle, so that the area of the first area is reduced.

In one embodiment, as shown in fig. 13, the inclined plates 2113 have three sides, which are connected end to end and are all arc surfaces, so that the benefit of the appearance structure is that large particulate matters cannot be clamped between two adjacent inclined plates 2113 when the inclined plates 2113 rotate inwards, and the arc surface structure can push the large particulate matters to the middle area, so that the operation is smoother in actual use.
