Background
The biomass fuel is fuel produced by burning biomass material, mainly agricultural and forestry waste (such as straw, sawdust, bagasse and rice chaff), and is mainly different from fossil fuel. In the current national policy and environmental protection standard, the direct combustion biomass belongs to a high-pollution fuel, is only used in a rural large stove and is not allowed to be used in a city. The biomass fuel is a novel clean fuel which is formed (such as block and particle) and can be directly combusted by using agriculture and forestry wastes as raw materials and carrying out processes of crushing, mixing, extruding, drying and the like.
The manufacturing process of the biomass fuel is to make wastes into various shapes through processes of crushing, mixing, extruding, drying and the like, and the wastes are generally made into long-strip cylindrical shapes in China; but there are a lot of biofuel powder, spherical particles or impurities in the manufacturing process, and it is necessary to screen out all of them.
In the prior art, most of the devices use a screen to screen out powder, round particles and impurities of cylindrical biomass fuel, but in the screening process, if fuel particles falling into a platform are too many or have a large impact speed, the fuel particles roll down in an oblique direction in a disordered manner, if the cylindrical biomass fuel is just in a vertical state and passes through the screen, the biomass fuel in the vertical state can be screened out through screening holes on the screen, and the screening effect is affected, patent application No. 201810291754.5 describes that when the cylindrical particles incline downwards along a first slideway, the lower ends of the cylindrical particles touch a bullet block and push the bullet block inwards for a certain distance, the bullet block can drive a rotating disc to rotate, the rotating disc drives a first push plate to move towards the direction of the first slideway, a second push plate pushes the lower end of the first push plate, because the middle part of first slurcam rotates to be connected in the frame, so the upper end of first slurcam can make curved removal and upwards stir the cylinder granule to the direction of second slide, makes the cylinder granule enter into in the first slide. When spherical particles, powder or impurities are separated from the first slide way, the motion trail is parabolic, and the gravity center can be quickly separated from the first slide way due to the short length of the spherical particles, the powder or the impurities can directly fall on the second push plate, slide to the first push plate from the second push plate, and finally fall out from the first push plate, the problems are solved by the technical scheme that the spherical particles, the powder or the impurities are pushed by the cylindrical particles to touch the elastic block to trigger screening work, the practical execution is ideal, the screening reliability is low, and after the spherical particles, the screening structure is distributed in a large quantity and is extremely complex; therefore, the biomass fuel screening device is designed, the problem that the biomass fuel in a vertical state passes through the screening holes in the screen can be solved, and the design problem of the above patent can be overcome.
