Granulator and cutter device thereof

Abstract

The invention provides a cutter device of a granulator. The cutter device comprises a sector disc. A plurality of cutter bars which extend along the axial direction of the sector disc are fixed onto the peripheral direction of the sector disc, cutters which radially extend along the sector disc are arranged on the cutter bars, and all the cutters are positioned on different locations in the axialdirection of the sector disc. The invention further provides the granulator. The granulator comprises a bed, two gear ring dies, a power mechanism and the cutter device. The gear ring dies mesh with each other; die holes are formed in the gear ring dies; a feed channel is arranged on the bed, and an outlet of the feed channel is formed in meshing portions of outer rings of the two gear ring dies;the sector disc which is arranged on the bed is coaxial with the gear ring dies, and the periphery of the sector disc peripherally extends along the inner rings of the gear ring dies; the cutter barsare fixed onto the periphery of the sector disc, and the cutters are arranged at the inner rings of the gear ring dies. The cutter device and the granulator have the advantages that the cutter deviceof the granulator is low in stress, convenient to replace, difficult to abrade and long in service life; stable load is applied to the granulator, the granulator is long in service life, low in energyconsumption and high in yield and production efficiency, and the cutters are convenient to replace.

Description

technical field [0001] The technology relates to a granulator, which is used to press crushed feed, biomass particles, etc. into high-density material rods, and also relates to a cutter device of the granulator, which is used to cut the material rods. Background technique [0002] Existing pressure roller ring die pellet mill, see figure 1 , including a ring die 1 fixed on the machine base, and a die hole is opened radially on the ring die; a rotating main shaft 2 is arranged in the ring die, and a pressure roller shaft 3 is fixedly arranged on both sides of the main shaft, and two pressure rollers 4 They are respectively arranged on the pressure roller shaft 3 through bearing rotation. There are lubricating oil holes for lubricating the bearings on the pressure roller shaft. The outer peripheral surface of the pressure roller is inscribed with the inner peripheral surface of the ring die. When the main shaft rotates, the pressure roller always moves along the inner perip...

AI Technical Summary

Problems solved by technology

Its disadvantages: the two pressure rollers of the pressure roller ring die granulator are pressed from the inside to the outside at the same time, and the ring mold is stressed from the inside to the outside, which is easy to crack and damage; the pressure roller and the ring mold slide relatively, and the material is easy to be blocked in the pressure roller Between the ring die and the ring die, the load is heavy, and the main parts such as the pressure roller, the pressure roller shaft, and the ring die are under great stress, and the temperature rises, and they will be damaged after a period of use; the power consumption of the motor is high, the output is low, and the energy consumption is high; because The pressure roller should be sealed in a cavity including the ring die, etc., and the lubricating oil hole is on the pressure roller shaft. It is very inconvenient to open the cavity when adding lubricating oil; at the same time, because the temperature of the parts is high, it is necessary to When adding lubricating oil, it needs to stop when adding lubricating oil, so the production efficiency is low

The integral cutter simultaneously cuts off the rods coming out from the outer ring of the ring die and located in the same axial direction of the ring die. The force on the cutter is increased, and the impact load received is also large, and the cutter is easy to wear and damage
