Description
Technical field
The invention belongs to field of biological energy source, be specifically related to a kind of speed changing type stalk block making machine and the shaping method of stalk briquette.
Background technology
China is just being devoted to allow discarded agricultural crop straw be converted into high-grade biomass energy, with fossil fuels such as Substitute For Partial coal, oil, alleviates the situation of rural energy anxiety, and improves the income of peasant, realize the sustainable development of rural energy.Stalk is as a kind of important bioenergy resource, and amount is sufficient greatly and cheap.After straw compressing and forming, its density increases
8 ~ 10 times, fuel value increases, and after burning, the discharge of dust and other indexs is lower than coal, can realize CO2, SO2 and fall row, reduces greenhouse effects, and environmental benefit is obvious, can be used as high-grade energy product.
At present, on domestic market, the forming machine for straw of various structure just arises at the historic moment, corollary equipment is collected stalk from field, dry, pulverize, dry, shaping after burn again, the high efficiency striving for stalk utilizes.Its forming principle of straw briquetting machine is by after crushed stalk, send into forming machine, under external force, be compressed into the shape of needs, become for ease of transport, the energy being adapted to combustion of industrial boiler, Substitute For Partial coal as fuel, and then realizes stalk resource substantially, industrialization utilizes, and solves crop straw burning problem.
Found by market survey, various forming machine for straw is different according to structure, is roughly divided into 3 kinds, and spiral squeezing type, piston punching type and roller die grind stalk block making machine.Roller die grind stalk block making machine because generally not needing external heat during its work, raw aqueous rate good to adaptability to raw material can produce at 10%-30%, be therefore current test, use wider stalk briquette equipment.But in the prior art, roller die stone roller stalk block making machine has following weak point: one, owing to being that therefore its power is large, energy consumption is high by arbor wheel driven type technology-forcing extruded material, yielding poorly; Two, extrude dynamics wayward, extruding force is spent senior general and is caused traffic congestion, take a lot of work, require great effort while affect operating efficiency, extruding force spend young pathbreaker cause stalk not granulate or to granulate after easily fragmentation; Three, owing to adopting butter lubrication, cause axle easily broken, bearing, mould, accessory etc. are fragile, and constantly maintenance of equipment, therefore delays production, belong to highly energy-consuming, inefficient equipment; Four, due to the mechanical friction of whole process, cause the module temperature of cuber to raise gradually, high temperature causes stalk cannot be shaping, and therefore the stalk block making machine of this structure cannot long time running, affects operating efficiency.
Summary of the invention
For solving the problem, an object of the present invention be to provide a kind of can the stalk block making machine of speed change, two of object of the present invention is to provide the compound stalk forming method that stalk block making machine of the present invention is applicable to various stalk.
