Technical field
The present invention relates to a kind of bimodulus vertical type biomass stalk extrusion formation equipment, be applicable to biomass material, the equipment of especially stalk preliminary treatment, material forming is particularly useful for making stalk compact formed for bar-shaped, to adapt to the requirement to its density and intensity of subsequent combustion and gasification.
Background technology
Fossil energy such as coal and oil is exhausted day by day, and living beings are subjected to the pay attention to day by day of countries in the world as a kind of regenerative resource.China is large agricultural country, and exploitation biomass combustion and gasification technology are very important.Yet with respect to fossil energy, living beings are widely distributed and disperse, and its very light in weight, cause direct cost of transportation higher.The biomass energy metric density is low in addition, can not adapt to the requirement of existing burning and gasification installation.Exploitation biomass moulding technology is the effective behave that addresses these problems.
Prior biological matter forming technique is based on the horizontal spiral pressurizing unit, its equipment bulky complex, and floor space is big, and produces severe noise and pollute.The said equipment is easy to cause faults such as sticking machine obstruction when raw material humidity is big in addition, and production efficiency is reduced, and has increased cost such as maintenance cost.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned reaction unit, provide a kind of floor space little, production capacity is big, and the low biomass moulding equipment of noise.
The present invention is achieved through the following technical solutions:
A kind of vertical type biomass stalk extrusion formation equipment comprises hopper, plain grinding dish, and wherein the plain grinding dish is positioned at the bottom of hopper.
According to former of the present invention, also comprise rotating shaft and discharging opening.
According to the preferred embodiments of the invention, described equipment comprises that the hopper of at least two series connection (is positioned at be called " the one-level hopper " of its upper side; The hopper that is positioned at the bottom is called " secondary hopper "), evenly inlay some die orifices by circumference on the plain grinding dish of feed hopper bottom.The die orifice that is arranged in the one-level hopper is called the one-level die orifice, and the die orifice that is arranged in the secondary hopper is called the secondary die orifice.
According to the present invention, more highdensity if desired living beings can increase the number of series connection hopper, as 3 or 4, or more.
According to the preferred embodiments of the invention, in two hoppers, be symmetrical arranged two squeegee rollers, connect by the central rotating shaft that runs through two hoppers.With the die orifice correspondence position, described squeegee roller side is provided with the engaging tooth that can be adapted to the die orifice correspondence position above the plain grinding dish.Two squeegee rollers in the series connection hopper are installed in the two ends of same horizontally disposed crossbeam respectively, and described crossbeam is installed on the through hole that passes on the plain grinding dish, and connects by central rotating shaft.The discharging opening bottom is provided with unloads charging tray (centering on central rotating shaft but non-one), can be driven by low-power machine.Described central rotating shaft extends to the bottom big belt pulley by the hopper through hole, and it runs up by motor-driven.Thereby make the biomass straw extrusion modling of pulverizing.
According to technical scheme of the present invention, the die orifice of described plain grinding dish is cylindric, round table-like, is preferably the inverted round table shape.The shape of the plain grinding dish of series connection can be identical or different.
According to embodiment of the present invention, suitable humidity need be pulverized and keep to raw material in advance.Preferably biomass material is crushed to 40-120mm in advance, preferred 50-100mm, the feed bin volume in two hoppers is 0.3-1m
3, preferred feed bin volume is 0.5-0.8m
3, more preferably 0.6m
3, firsts and seconds die orifice diameter is 20-60mm, preferred 30-40mm, and the tapering of inverted round table is 1-5 °, be preferably 1-3 °, the total specified power of motor is 35kW, and treating capacity can reach 500t/h at least, preferred 600t/h, more preferably 650t/h, the biomass density after the moulding can reach 1-1.5kg/m
3, preferred 1.1-1.2kg/m
3
Former of the present invention has reduced floor space owing to adopted vertical structure, effectively utilizes the factory building space; Because die orifice is arranged to the inverted round table shape, its with the squeegee roller engagement in the effective compression forming of living beings; Owing to be provided with two hoppers and the supporting extruding facility of series connection, can make the double compression of living beings powder, effectively increase the density behind the biomass moulding, and can reduce the discharging opening dust emission, improve raw material availability and reduce the loss of relevant device, increase the service life; Because die orifice is embedded on the plain grinding dish, can be convenient for changing according to the requirement of raw material and moulding, and helps saving the repair time.Can prevent effectively that material from splashing by the device for discharging of low-power machine drive owing to adopted, avoid the material group, and reduced vibration and noise.
The present invention can enhance productivity, save floor occupying area, realizes continuous production, is applicable to that biomass straw is compact formed.
