Embodiment Construction

[0019] like figure 1 A stepped mold straw granulation device shown includes a feeding chamber 21, a forming die 22 arranged at the bottom of the feeding chamber 21, a rotating shaft 24 driven by a power mechanism that vertically penetrates the forming die 22, and is symmetrical to the rotating shaft 24. The two transmission rods 26 extending outward, and the pressure rollers 25 connected to the transmission rods 26 are coaxially rotated respectively. The upper surface is in the shape of three layers of steps descending from the center of the circle to the edge, and each layer is respectively provided with a forming hole 23. The pressure roller 25 is in the shape of a boss whose diameter increases along the extension direction of the transmission rod 26. The pressure roller 25 and the forming die 22 to match the shape of the upper surface.

[0020] It also includes a rubbing and breaking machine whose discharge port communicates with the charging chamber 21 feed ports. The rub...

Abstract

The invention discloses a stepped mold straw granulation device. The device comprises a charging chamber, a molding mold located at the bottom of the charging chamber, a rotation shaft which vertically goes through the molding mold and is driven by a power mechanism, a transmission bar extending from the rotation shaft to outside, and a compression roller rotatingly connected to the transmission bar. The molding mold circumference where the compression roller carries out revolution along with the rotation shaft is provided with a molding hole. The upper surface of the molding mold is in a shape of a declining ladder from the circle center to the edge. The shape of the compression roller matches with the shape of the upper surface of the molding mold. The upper surface of the molding mold is in a shape of a declining ladder from the circle center to the edge and the shape of the compression roller matches with the shape of the upper surface of the molding mold so that the diameter of the outer side of the compression roller is increased. Under the condition of an invariant angular velocity, a compression roller outer side linear velocity is increased, sliding friction between the compression roller and the molding mold is greatly reduced, roller compression effects are ensured, a straw crushing degree is reduced, straw crushing energy consumption is reduced and a straw granulation cost is reduced.

Description

technical field [0001] The invention relates to the field of straw processing equipment, in particular to a stepped die straw granulation device. Background technique [0002] Extrusion molding is currently a major way of processing straw nearby. It refers to crushing the straw and pressing it into granules without adding any additives and binders. Extrusion molding technology includes screw extrusion, piston compression, two hot-press forming technologies, and roll-forming cold-press forming technology; the two hot-press forming technologies require high processing precision and good wear resistance of materials, and the equipment purchase and use The high cost will increase the cost of straw extrusion molding, which is not conducive to the economic rationality of straw resource utilization; the working principle of roll forming is: a number of forming holes are opened on the forming die, and the crushed straw scraps are crushed by pressing rollers. Squeeze into the feed p...
