Abstract
The invention discloses a flat mould net mould disc biomass molding machine which comprises a machine frame, a material inlet bin arranged on the upper portion of the machine frame and a material receiving bin arranged under the material inlet bin. A compression roller is arranged in the material inlet bin, a net disc face type mould disc is arranged in the material receiving bin, the compression roller is in clearance fit with the net disc face type mould disc, and a material outlet is arranged on the material receiving bin. At least one ring of molding holes are arranged on the disc face of the net disc face type mould disc. Each molding hole is formed by a hopper-shaped material inlet section on the upper portion, a conical transition section on the middle portion and a cylindrical molding section on the lower portion, and an upper end opening of the hopper-shaped material inlet section is fan-shaped. The compression roller or the net disc face type mould disc is in transmission connection with a power mechanism. The molding machine is simple in structure, and a triangle area does not exist on the disc face of the net disc face type mould disc to enable the material inlet area duty ratio of the net disc face type mould disc to approach 100%. The molding machine overcomes the shortcoming that a traditional mould is apt to grind biomass raw materials into casings, and can effectively improve production efficiency and reduce unit production power consumption of equipment.
Description
Technical field
The invention belongs to biomass molding fuel production equipment technical field, the netted mould biomass forming machine of particularly a kind of flat-die.
Background technology
The natural form of biomass material is loose unordered, and volume is big, proportion is little, and the weight of unit volume is about 50-110 kg/m
3If biomass material directly as fuel, then requires stove to have bigger burner hearth, the biomass material firing duration is short simultaneously, and fuel adds frequent, and efficiency of combustion is lower.Biomass molding fuel then is to form through the biomass material compacting of former to natural form, and the bulk density that it has changed living beings has improved energy density, has application value widely.
Biomass forming machine comprises the flat-die biomass forming machine; Its operation principle is: rely on the pressure roller of make-up machine and a large amount of frictional heat that the violent rubbing action between biomass material produces; Make that the lignin that contains in the biomass material is softening, cohesive force increases; Intrinsic cellulose synergy in lignin after softening and the biomass material makes living beings be transformed into biomass molding fuel gradually.The characteristics of existing flat-die biomass forming machine are: simple in structure, and volume compact, with low cost.But the moulding mould of flat-die biomass forming machine and moulding hole are wear-out part, and wearing and tearing fast very easily take place, and need regularly process the moulding hole during use, to guarantee its forming ability.The existing monoblock type mould of moulding mould also has sectional die, and in order to prolong the service life of moulding mould, the material of moulding mould often adopts wear-resisting alloy steel.But; Because biomass materials such as stalk tend to carry secretly many silts, dust in collection process; The more important thing is that the alkali metal content in the biomass materials such as stalk is higher; The wearing and tearing of the moulding mould that silt, dust and alkali metal are processed wear-resisting alloy steel in the extrusion modling process are still very serious, cause be difficult to above 500 hours the service life of moulding mould.In addition, adopt wear-resisting alloy steel machine-shaping mould not only to improve difficulty of processing, also increased its manufacturing cost and maintenance cost.Therefore,, be lowered into the manufacturing cost of pattern dish and biomass forming machine simultaneously, adopt suitable moulding mould to become the technical bottleneck that the restriction biomass forming machine is promoted the use of for the rate of wear of slowing down the moulding mould and the service life of improving the moulding mould.
At present, the netted card formula mould moulding hole of flat-die biomass forming machine generally is made up of circular cone pan feeding section and cylinder profiled section, between the circular feeding mouth in the moulding hole that distributes on the netted card formula mould, exists the zone of handing-over, generally is referred to as the trigonum.When pressure roller rolls through the trigonum; Can cause the invalid of biomass material between pressure roller and the netted card formula mould rolled; Cause make-up machine ineffective power consumption to occur; Also causing effective pan feeding area of make-up machine to reduce, is that the moulding hole of 30mm is an example with the diameter, and general dutycycle can only reach 30%～50%.In addition,, have a strong impact on the operating efficiency of make-up machine because biomass material is rolled into hard shell in the trigonum, and very responsive to the gap of pressure roller and netted card formula mould, quickened the wearing and tearing on netted card formula mould surface greatly.In a word; Not only dutycycle is low for the structure of existing mold, inefficiency and service life short, and the mechanical power of significant proportion is arranged because the extrusion friction conversion for frictional heat, makes the unit power consumption of production equipment high; Production cost is too high, has seriously hindered applying of forming technique.
