Biomass fuel particle treatment equipment

Abstract

The invention belongs to the technical field of biomass fuel screening, and particularly relates to a biomass fuel particle treatment equipment which comprises a base, a feeding hopper and a screening platform. According to the biomass fuel particle treatment equipment, a crank, a driving pin shaft, a swing pin shaft and a fork-shaped structure are designed to form a swing mechanism, the swing mechanism can achieve quick-return movement, it is achieved that a waste conveying plate can move rapidly in a obliquely-upward mode, and qualified biomass fuel clamped between the waste conveying plate and the screening platform bears sudden upward push force to be separated from screening holes in the screening platform through the rapid obliquely-upward movement of the waste conveying plate; for the unqualified fuel particles, after the lower ends of the unqualified fuel particles pass through the screening holes and fall onto the upper end face of the working face of the waste conveying plate, the upper ends of the unqualified fuel particles are quite easy to be separated from the screening holes due to the small size, and then the unqualified fuel particles completely fall onto the working face of the waste conveying plate and then obliquely slide down along the working face of the waste conveying plate; and since the unqualified fuel particles are completely located on the working face of the waste conveying plate, almost no influence is generated on smooth downward sliding of the unqualified fuel particles when the working face of the waste conveying plate conducts reciprocating motion.

Description

[0001] Technical field [0002] The invention belongs to the technical field of biomass fuel screening, and in particular relates to processing equipment for biomass fuel particles. Background technique [0003] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels. In the current national policy and environmental protection standards, direct combustion of biomass is a highly polluting fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly that biomass briquette fuel is made of agricultural and forestry waste as raw materials, through crushing, mixing, extrusion, drying and other processes, and made into various shapes (such as block, granular, etc.), which can be A new type of clean fuel for direct combustion.

Problems solved by technology

[0005] In the prior art, most of the screens are used to screen out the powder, round particles and impurities of the cylindrical biomass fuel. However, during the screening process, if there are too many fuel particles falling into the platform or have large In the case of a high impact speed, the fuel particles will roll down in a chaotic direction in an inclined direction. If the cylindrical biomass fuel happens to be in a vertical state and passes through the screen, the vertical biomass fuel may pass through the screen. The screening holes on the net are screened out together, which affects the screening effect. The patent application number of the prior art patent is 201810291754.5. The bullet will push the bullet inward for a certain distance, the bullet will drive the rotating disk to rotate, and the rotating disk will drive the first push plate to move in the direction of the first slideway, and the second push plate will push the lower end of the first push plate, Since the middle part of the first push plate is rotatably connected to the frame, the upper end of the first push plate will move in an arc toward the direction of the second slideway and move the cylindrical particles upward so that the cylindrical particles can enter the first in the slide

When spherical particles, powder or impurities leave the first chute, their trajectory is a parabola. Because of their short length, the center of gravity will quickly leave the first chute, and will directly fall on the second push plate, and from the first The technical scheme that slides from the second push plate to the first push plate and finally falls out from the first push plate solves the above problems. It triggers the screening work through the push of cylindrical particles touching the bullet block. The actual execution is relatively ideal, and the screening reliability is relatively good. It is relatively low, and after commercialization, the screening structure is arranged in a large number, and the structure is extremely complicated; therefore, a biomass fuel screening equipment is designed, which can not only solve the problem that the biomass fuel in the vertical state passes through the screening holes on the screen, but also can Overcoming the Design Problems of the Patents Above
