The beneficial effects of the utility model are:
The ring mould life-span of the utility model granulator is long, output is big, and raising product quality and output, cut down the consumption of energy (the moulding energy consumption accounts for whole workshop total energy consumption 50%-70%), the aspects such as (expense of ring mode loss account for more than the maintenance cost 40%-75% in whole production workshop) that reduces production costs are all had great importance.
Below in conjunction with drawings and Examples; further specify the utility model; but the utility model is not limited to these embodiment, any on the utility model essence spirit improvement or substitute, still belong to scope required for protection in the utility model claims.
Description of drawings
Fig. 1 is used for the schematic diagram of ring mould of the granulator of biomass molding fuel for the utility model.
The specific embodiment
Followingly the granulator that is used to prepare biomass molding fuel of the present utility model is described with reference to Fig. 1.Granulator of the present utility model comprises body, rotates the ring mould 10 of installation and be arranged on two pressure rollers (granulator is the technology of knowing in the prior art, so meaning not shown in the figures illustrates its detailed construction) that encircle mould inside with the pivot center of ring mould with paralleling with respect to body.
Effective compacting width W of ring mould 10: 80-160mm (such as selecting 120mm for use), the design power of granulator and ring die worker are directly proportional as area.
The nib of ring mould 10 is by equilateral triangle principle arrange (see among Fig. 1 shown in the label A).Particularly, each nib of ring mould 10 is divided into six groups on the direction of the pivot center Y of ring mould, each organizes that the residing plane of nib is parallel to each other and perpendicular to the pivot center Y of ring mould, wherein one of them nib of one group with last one group in or two the most contiguous nibs formation equilateral triangle layouts in next group.
The compression ratio 5-8 (such as selecting 6 for use) of ring mould selects different apertures and different compression ratios according to the requirement of property of raw material and shaped fuel.
The percent opening of ring mould is 20%-50% (such as selecting 30% for use), and die throat diameter d is big more, and ring mould percent opening is high more.Percent opening is high more, and discharging is unobstructed more, but the nib wall thickness reduced, and ring mould intensity reduces, and product strength is big.Under the certain situation of die throat diameter, improve the percent opening of ring mould, the wall thickness between the nib reduces, but minimum wall thickness (MINI W.) must satisfy the needs of ring mould intensity.Guarantee ring mould intensity, anti-stop ring mould cracking.
The nib of ring mould 10 comprises (this are the technology of knowing in the prior art, so meaning not shown in the figures illustrates) such as straight hole, vent, male-tapered hole and internal tapered holes.Vent claims release aperture again, and different nib forms is fit to different raw materials.In the same ring mould, the straight hole length on the surpassed distance trough rim is also all different with the straight hole length in ring mould centre.The same with resistance down to the pressure of pressing mold at nip roll, the material of surpassed distance trough rim is extruded grinding undercut easily, and does not enter nib.So generally two rows have vent on the surpassed distance trough rim.
The roughness value of suitable nib is should be between 0.7--1.5 (such as selecting 1.0 for use).Roughness also is to weigh the important indicator of ring mould quality.Under same compression ratio, roughness value is big more, and it is big more that material is extruded resistance, and discharging is difficult more, and excessive roughness also influences the quality of particle surface.
The speed setting of ring mould is 60-110 rev/min (such as selecting 80 rev/mins for use).The height of rotating speed of ring mould has influence on thickness of feed layer in the crush zone and the material time by nib, and then influences granulator output and granular mass.When speed is too high, the power consumption height, ring mould revolution output particle is few under the identical output condition, the bed of material is thin in the crush zone, axial bed of material skewness, and the particle of making is soft, it is irregular axially to extrude particle length, powder is many, and also easily skids for the higher material of moisture, even can not granulate at all; Though the granular mass that lower ring mould speed is made is good, and is bigger to yield effect.
The pressure roller diameter is 0.42-0.48 (such as selecting 0.475 for use) with the ratio of the internal diameter R of ring mould.Under the identical ring mould, the nip roll diameter is big more, and the triangle extruding scope that forms between ring mould and the nip roll is big more, is beneficial to extruding more, but will consider extruding force balance on main tapping between two pressure rollers of twin pressure roller granulator, the reaction on the pressing mold; So suitable pressure roller diameter is crucial.
The profile of tooth of pressure roller can adopt teeth groove shape, the honeycombed of edge sealing.This pressure roller coiled strip performance is good, is not easy sliding toward both sides during the material extruding.
