A kind of living beings multitower single lead screw ex truding briquetting machine
Technical field
The utility model relates to a kind of extrusion formation equipment, particularly relates to a kind of living beings multitower single lead screw ex truding briquetting machine.
Background technology
The processing and forming of living beings is main paties of the refuse efficiency utilization such as wooden industrial wood waste, crop stalk, papery waste material.For extrusion formation equipment, wish the work that energy is energy-conservation, efficient and reliable and stable.At present both at home and abroad conventional extruder structure comprises die cavity, be located at filler briquetting above described die cavity and pusher oil cylinder, makes material compression shaping, and send product crushing block by pusher oil cylinder with coordinating of clamp cylinder by the extruding of filler briquetting.For improving the production capacity of extruder, generally there are two kinds of approach:
One is the cross section increasing crushing block, and machine increases the height and width of crushing block, increases the weight of crushing block.Increase equipment capacity in this way, the problem brought is: when the cross section of crushing block increases, for meeting necessary typed pressure, extruded oil cylinder must strengthen, under identical discharging frequency, the discharge capacity of Hydraulic Station must strengthen, and complete machine power must increase a lot.Such device fabrication cost, equipment operating cost will significantly increase.Simultaneously for increasing the cross section of crushing block, corresponding feed system also must strengthen.But feed system is when increasing to a certain degree, can bring the unstability of charging, so the increase of the cross section of crushing block has certain restriction; In addition, the size of crushing block own also has specification to limit, and is inconvenient to be only increase yield and change.
Two is the discharging frequencies by improving equipment, increases the quantity of crushing block in the unit interval, thus increasing device production capacity.But increase equipment capacity by this method, must increase the discharge capacity of Hydraulic Station, such complete machine power must increase a lot.This method causes device fabrication cost equally, equipment operating cost significantly increases, and while frequency raising, easily causes equipment to cross quick-wearing, and then affect the life-span.
Can find out and increase production capacity by said method, all good fortune can increase device fabrication cost and equipment operating cost greatly, and affect the job stability of equipment.For above-mentioned technical problem, current industry does not also have better solution, can only improve in above-mentioned thinking.
If do not increase the cross section of crushing block, and increase the length of crushing block, be also conducive to improving production capacity.In addition, increase the length of product, generally can not affect product and use, also help the accumulating of product.But the length increasing product must increase the width of packed tower, and can bring two problems when packed tower is widened: after 1, packed tower is widened, corresponding feed system also must strengthen.But feed system is when increasing to a certain degree, can bring the unstability of charging, so the increase of crushing block length has certain restriction.2, after packed tower is widened, shaping mold cavity also must be widened, and this brings a difficult problem to the manufacture of die cavity.In addition, when packed tower lengthens, because filler can not ensure evenly, filler briquetting will be caused large at length direction force difference, long-term work is also unstable.
Can find out, if above-mentioned two difficult problems can be broken through, by increasing the length of crushing block, increase production capacity, by the effect obtained be: equipment capacity is multiplied, and the manufacturing cost of equipment and equipment operating cost slightly increase.
