Description

Sickle-shaped straight-edge blade set for crushing biomass fuel

Technical Field

The utility model belongs to the mechanical field of biomass fuel processing relates to a blade, especially a smash biomass fuel's hook type straight sword blade group.

Background

The crushing processing is one of the very important processes in the biomass fuel particle process, the biomass fuel body is generally straws, the compressive strength of the straws is small, the fibers are long, the probability of collision and self-crushing among the materials is small, and therefore in order to ensure that the materials can be crushed fully in the crushing process and can pass through the conveying mechanism, the crushing is most effective by adopting the shearing force and the grinding force. At present, the existing straw crushing process generally adopts a straight-edge knife to cut up, and the final crushed particle fineness is not ideal.

The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a smash biomass fuel's straight sword blade group of hook type, includes the pivot, its characterized in that, the pivot on from last down all welded in proper order blade disc one, blade disc two, blade disc three and blade disc four, blade disc one go up the equidistant a plurality of blades that are fixed with of circumference, blade disc two goes up the equidistant a plurality of blades two that are fixed with of circumference, the equidistant a plurality of blades three of circumference are fixed with on the blade disc three, the equidistant a plurality of blades four of circumference are fixed with on the blade disc four, blade one, blade two, blade three, blade four be the hook type.

Specifically, the number of the first blades is four, the number of the first blades is six, the number of the first blades is eight, and the number of the first blades is ten.

Specifically, the diameters of the first cutter head, the second cutter head, the third cutter head and the fourth cutter head are all 500 mm.

Specifically, the distance between the top of the first blade and the central axis of the first cutter head is 700 mm; the distance between the top of the second blade and the central axis of the second cutter head is 700 mm; the distance between the top of the third blade and the central axis of the third cutter head is 700 mm; the distance between the top of the blade IV and the central axis of the cutter head IV is 700 mm.

Compared with the prior art, this biomass fuel's hook type straight edge blade group has following advantage:

the sickle-shaped straight-edge blade group for crushing the biomass fuel comprises four layers of blades, the number of the blades on each layer is gradually increased, after materials to be crushed are added from the upper part, the first cutter head, the second cutter head, the third cutter head and the fourth cutter head synchronously rotate along with the rotating shaft, the materials are crushed in a grading mode in the crushing process, the number of the blades from top to bottom is increased, the distance between the blades is reduced, the processed materials are fine in particles, and meanwhile the loss of the blades is reduced.
