Abstract
A circular mould formed by extruding biomass briquette fuel comprises a flange and a circular mould ring provided with a mould hole, wherein two ends of the circular mould ring are provided with connectors, and the flange is fixedly connected with one of the connectors through a fastening element. The circular mould is characterized in that the front end of the flange is provided with a tapered chamfer, and the angle of the tapered chamfer is 15 degrees to 30 degrees. The flange is provided with the tapered chamfer, so mechanical strength of the flange is enhanced, operation reliability of equipment is improved, and service life of the equipment is prolonged.
Description
Technical field
The utility model relates to the Biomass Energy Technology field, especially relates to a kind of parts of biomass molding fuel ring model extrusion equipment, specifically is applied to encircle on the die forming machine ring mould that pushes, seizes material.
Background technology
China has abundant agricultural straw resource and the forest reserves, and the crops annual production is annual about 600,000,000 tons according to statistics, amounts to approximately 300,000,000 tons of standard coals, about 1.5 hundred million tons of forestry residue.In recent years, along with improving constantly of agricultural economy level, life in the countryside increases gradually with high-grade commercial energy in the energy, the shared ratio of stalk is also increasing, a large amount of discarded stalks are burned in the field, this phenomenon is not only wasted a large amount of biomass energies, and environment is caused severe contamination.Biomass solid forming machine is under uniform temperature and pressure-acting, originally living beings drying that disperse, that do not have definite shape and pulverizing is pressed into have various shaped fuels definite shape, that density is larger.Biomass granule fuel has efficiently, clean, igniting easily, CO
2The advantages such as zero-emission, the fossil fuels such as alternative coal are applied to civil area and the industrial circles such as boiler combustion, generating such as cooking, heating, more and more get more and more people's extensive concerning in recent years.
Biomass molding fuel forms by the forming machine extruding, and at present, biomass solid forming machine mainly contains three kinds of forms such as screw extrusion, piston punching press, mould rod formula.Wherein mould rod formula forming machine has the advantages such as high productivity, forming, is to produce biomass solid fuel enterprise preferred equipment.At mould rod formula forming machine; ring mould and pressure roller are the key working parts of forming machine; in the compacting chamber; material is shaped by nib under pressing mold and pressure roller extruding, is mainly used in particle or block shaped fuel production, and raw material accommodation is extensive; can be used for processing the long raw material of the fibers such as wood chip, stalk, rice husk; generally need not heat, granular fuel is the cylindric of diameter 6～12mm, and patch fuel is the bulk about 32 * 32mm.Can adjust as required mold hole dimension, change shape and the size of shaped article.The ring mould comprises flange and is provided with the ring mould circle of nib, and ring mould circle two ends are provided with interface, flange and one of them interface be fixedly connected with securing member, flange is provided with flange hole, for cylindrical.Since pressure roller long-term with ring mould friction and extruding, large to the active force of ring mould, in service in reality flange often occurs and burns out, and easily loosening and fracture of flange screw, causes equipment not move, the serious damage that causes equipment.
The utility model content
The utility model provides a kind of ring mode structure of biomass molding fuel extrusion modling for the problem that prior art exists, and mechanical strength is high, is not easy to damage, and improves the service life of equipment.
The technical scheme that the technical problem that the utility model solves adopts is:
A kind of ring mould of biomass molding fuel extrusion modling, comprise reinforcing flange and the ring mould circle that is provided with nib, ring mould circle two ends are provided with interface, and reinforcing flange is fixedly connected with securing member with one of them interface, it is characterized in that the front end of reinforcing flange is provided with conical chamfering.The front end of reinforcing flange is provided with conical chamfering, and its mechanical strength obviously improves.
During implementation, the chamfer angle of above-mentioned conical chamfering is 15 degree-30 degree.
The beneficial effects of the utility model are: owing to be provided with conical chamfering at flange, strengthened the mechanical strength of flange, improved equipment operational reliability and service life.
Description of drawings
Below in conjunction with drawings and Examples utility model is further specified.
Fig. 1 is the utility model example structure schematic diagram.
Among the figure: 1, ring mould circle 2, reinforcing flange 11, interface 12, nib 22, conical chamfering.
The specific embodiment
In Fig. 1, a kind of ring mould of biomass molding fuel extrusion modling, comprise reinforcing flange 2 and the ring mould circle 1 that is provided with nib 12, ring mould circle 1 two ends are provided with interface 11, and reinforcing flange 2 is fixedly connected with one of them interface 11 usefulness screw rod securing member, and the front end of reinforcing flange 2 is provided with conical chamfering 21, the chamfer angle of conical chamfering 21 is 20 degree, the front end of reinforcing flange 2 is provided with conical chamfering 21, and its mechanical strength obviously improves, and has improved equipment operational reliability and service life.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from disclosed content of the present utility model all should be thought protection domain of the present utility model.
Claims (2)
