Abstract

The utility model discloses a biomass fuel particle granulator which comprises a feeding port and two ring molds. The two ring molds are two cylinders which are externally tangent with each other and rotate oppositely. The feeding port is positioned right above the site where the two ring molds are tangent, a plurality of pressed through holes are evenly distributed on each ring mold, all the pressed through holes on the same section face the circle center of each ring mold, and the pressed through holes are alternately distributed where the two ring molds are tangent with each other. The biomass fuel particle granulator reduces the energy consumption effectively and the total specific energy consumption in the granulation production process is 25 to 60 KWh per ton with a fall of over 70 percent compared with the traditional processing; simultaneously, a one-time granulation can be achieved when the humidity is 10 to 35 percent, thereby saving the process of drying; moreover, the temperature only needs increasing by 10 to 15 DEG after the granulation. The pressed particles have a general temperature of 55 to 60 DEG and can be packed directly without being cooled off, thereby saving the process of cooling off and improving the work efficiency.

Description

A kind of biomass granule fuel granulator

Technical field

The utility model relates to the biomass fuel producing equipment, is specifically related to a kind of press-forming machine of biomass granule fuel.

Background technology

Fossil fuel such as coal, oil, natural gas are the core energy of industrial society, but they are non-renewable resources, and reserves are limited.According to International Energy Agency statistics, coal, oil, natural gas can have only 240 years respectively for the time limit of exploitation, 40 years and 50 years.Along with the develop rapidly of human economic society, the speed of energy resource consumption is more and more faster, and especially the continuous increase of fossil fuel consumption has caused the exhaustive exploitation to them, makes price go up day by day and gradually exhaustion; Simultaneously, high-intensity utilization discharges unnecessary energy and carbon element in a large number, has broken natural energy and Carbon balance, causes catastrophic effects such as depletion of the ozone layer, global warming, acid rain, has caused the very big worry of international community.If there is not the new energy to replace the leading position of conventional energy resource in energy resource structure, serious, the catastrophic energy and environmental crisis will take place in 21 century.

People focus on sight line on one's body the regenerative resource for this reason.Though solar energy, wind energy, small power station etc. are regenerative resources, can not carry out material production, and living beings can be contributed energy, can as coal and oil, produce 1,100 kinds of chemical products again.Compare with automobile-used regular gasoline as alcohol fuel, the discharging of carbon monoxide can reduce by 7%, and hydrocarbon can reduce 48%; Biodiesel is rich in oxygen, mixes use with ordinary diesel oil, can make burning more abundant, and according to detection, biodiesel is nontoxic, the energy biodegrade, and the biodiesel of interpolation 20% can reduce discharging sulfur dioxide 70%, reduces air toxicity 90%; Use biological plastics can solve white pollution problems.Biomass energy is a raw material with crop material, feces of livestock and poultry, agriculture and forestry organic waste material, organic garbage of city etc. simultaneously, makes it innoxious and resource, with luminous energy and the physical resources deep development and recycling that plant stores, meets the theory of developing a circular economy.Therefore, biomass energy can satisfy the needs of alleviating energy crisis, meets the requirement of protection environment, realization sustainable development again, is the inevitable choice that China carries out the regenerative resource development and use.

Traditional biomass granule fuel producing equipment comprises charging aperture, pressure roller, main shaft and pressing mold, raw material enters from charging aperture and falls on the pressing mold, rotating band dynamic pressure roller by main shaft rolls, under the squeezing action of pressure roller, raw material enters compression forming in the moulding hole of pressing mold, extrudes from the moulding hole other end.Adopt that above-mentioned producing equipment need consume a large amount of electric energy, equipment loss is big, production cost is high, usually specific energy consumption is 80～180kWh/t, under the bigger situation of humidity, need earlier raw material to be carried out drying and just can enter the producing equipment moulding, and particle heats up big after moulding, need again to cool off just and can pack, operating efficiency is low.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of biomass granule fuel granulator; it is big effectively to solve traditional producing equipment energy consumption; the production cost height; under the bigger situation of humidity, need to carry out drying earlier and can't a granulating, need to cool off earlier to pack behind the granulating simultaneously and cause ineffective problem.

In order to solve the problems of the technologies described above; the utility model adopts following technical scheme: a kind of biomass granule fuel granulator; it is characterized in that: comprise two ring moulds, two ring moulds are circumcircle cylinder and rotation in opposite directions, are evenly distributed with some compacting through holes on each ring mould.

Further, the compacting through hole on the same vertical section is all towards the ring mould center of circle in cross section, place.

Further, the compacting through hole distributes alternately at the tangent place of two ring moulds.

The utility model is owing to adopted technique scheme, effectively reduce energy consumption, the specific energy consumption of whole production pelletization is 25～60kWh/t, reduces more than 70% than tradition processing, simultaneously humidity be 10～35% o'clock can a granulating, save drying process, and after the granulating, only heated up 10～15 ℃, the particle temperature that compacting is come out generally has only 55～60 ℃, need not cooling can directly pack, and has saved refrigerating work procedure again, has improved operating efficiency.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the structural representation of ring mould in a kind of biomass granule fuel granulator of the utility model;

Fig. 2 is the transmission schematic diagram of ring mould in a kind of biomass granule fuel granulator of the utility model.

The specific embodiment

As shown in Figure 1; the embodiment of a kind of biomass granule fuel granulator of the utility model; comprise feeding mouth 3 and two ring moulds 1; two ring moulds 1 are circumcircle cylinder and rotation in opposite directions; feeding mouth 3 be positioned at two ring mould 1 tangent places directly over; be evenly distributed with some compacting through holes 2 on each ring mould 1; compacting through hole 2 on the same vertical section is all towards ring mould 1 center of circle in cross section, place; promptly suppress through hole 2 and be entad through hole; compacting through hole 2 distributes alternately at the tangent place of two ring moulds 1; promptly in tangent place's compacting through hole 2 asymmetric distributions of two ring moulds 1, it is out-of-level relative at tangent place that each suppresses through hole 2.Raw material need not to carry out drying and directly falls into from feeding mouth 3 between two ring moulds 1, driving rotating shaft 5 by motor 4 rotates, thereby rotating shaft 5 drives two external gear pumps 6 and rotates the rotation in opposite directions that realizes ring mould 1, the rotation in opposite directions of ring mould 1 is pressed into moulding in the compacting through hole 2 with raw material, particle after the moulding enters baling press from the end discharging of ring mould 1, need not cooling and directly packs.
