Description
Technical field
The invention belongs to the bioenergy field, be specifically related to the method for a kind of speed changing type stalk block making machine and stalk briquette moulding.
Background technology
China just is 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 peasant's income, realizes the sustainable development of rural energy.Stalk is as a kind of important bioenergy resource, and amount is large sufficient and cheap.Behind straw compressing and forming, its density increases
8 ~ 10 times, fuel value increases, and the discharging of the rear dust of burning and other indexs is lower than coal, can realize that row falls in CO2, SO2, reduces greenhouse effects, and environmental benefit is obvious, can be used as the high-grade energy product and is used.
At present, the forming machine for straw of various structures just arises at the historic moment on the domestic market, corollary equipment stalk collect from the field, dry, pulverize, dry, again burning after the moulding, strive for the high efficiency utilization of stalk.Its forming principle of straw briquetting machine is with after the crushed stalk, send into forming machine, under external force, be compressed into the shape that needs, one-tenth is for ease of transporting, be adapted to the energy of combustion of industrial boiler, Substitute For Partial coal acts as a fuel, so substantially realize stalk resource, the industrialization utilization, solve the crop straw burning problem.
Find by market survey, various forming machine for straw are different according to structure, roughly are divided into 3 kinds, and spiral squeezing type, piston punching type and roller die grind stalk block making machine.Roller die does not generally need external heat when grinding stalk block making machine because of its work, good to adaptability to raw material, the raw material moisture content can be produced at 10%-30%, is the wide stalk briquette equipment of current test, usage comparison therefore.But in the prior art, roller die grinds stalk block making machine and has following weak point: one, owing to being by arbor wheel driven type technology-forcing extruded material, so its power is large, energy consumption is high, yield poorly; Two, extruding dynamics is wayward, and extruding force is spent senior general and caused traffic congestion, takes a lot of work, affects when requiring great effort operating efficiency, and extruding force is spent the young pathbreaker and caused the stalk rear easy fragmentation of can not granulating or granulate; Three, owing to adopting butter lubricated, cause axle easily broken, bearing, mould, accessory etc. are fragile, and often therefore maintenance of equipment delays production, belongs to highly energy-consuming, inefficient equipment; Four, because omnidistance mechanical friction causes the module temperature of cuber to raise gradually, high temperature causes the stalk can't moulding, and therefore the stalk block making machine of this structure can't long time running, affects operating efficiency.
