Description
Technical field
The present invention relates to stalk fuel curing molding equipment technical field, more particularly, relate to a kind of improvement of plunger type straw fuel forming machine structure.
Background technology
All kinds of stalk (as corn, Chinese sorghum, beanstalk, wheat straw, peanut skin, wood chip, bamboo bits, the dregs of a decoction, chaste tree grass etc.) can be compressed into the moulding stick with certain density by straw fuel molding machine, are commonly called as " straw coal ", as industry or civilian fuel.
Stalk is that a kind of storage is huge, and the reproducible environment-friendly type energy.According to statistics, on the earth, the annual production of stalk green bio raw material is about 1,170 hundred million tons, China's stalk annual production about 700,000,000 tons, but its utilization rate is very low.The stalk that China rural area consumes every year only accounts for the sub-fraction of total output, and directly the thermal efficiency of burning is extremely low.The stalk of most area is burnt in field by as discarded object, not only wastes resource, also causes new public hazards.The best use way of stalk biomass raw material is curing molding, is compressed into the fuel rod with certain density by it, and its calorific value can match in excellence or beauty with coal facies, and its burning is free from environmental pollution, and lime-ash also can be made into fertilizer.Current domestic and international existing several stalk fuel curing molding equipment all has certain shortcoming: such as, spiral squeezing type forming machine big energy-consuming, and spiral wear is serious; Hydraulic drive piston formula forming machine productivity ratio is low, and energy consumption is higher; The forming machine changed a social system by the roller machinery producing feed, maximum shortcoming is that stalk need be compressing through certain hour " modification " process ability, and the forming blocks be pressed into (rod) density is low, can not as high-grade fuel.Domestic and international existing crank plunger type forming machine plunger number mostly is one (individual other has two), and productivity ratio is on the low side, and energy consumption is higher, and noise and vibration larger.
The patent No. of being declared by the applicant is the utility model patent of 200720011651.6 and 200820012310.5, quantitatively traditional design is breached at plunger, forming machine performance is had significantly improve, but these two kinds of forming machines and domestic and international existing plunger type forming machine same, still there are some shortcomings: the bronze slip lining tile frictional power loss that (1) is loaded on crank and eccentric disc is very large, and very easily grind watt (gummed) damage; (2) feed bin (space temporary before material press-in material mould) shape is arbitrary cuboid, has the dead band can accumulating material, can be produced huge bounce in dead band by the material compressed in feed bin, produces destruction to plunger and support.
Summary of the invention
The present invention is exactly for the problems referred to above, provides that a kind of energy consumption is low, production efficiency is high, non-damageable plunger type straw fuel forming machine.
For reaching above-mentioned purpose of the present invention, the present invention adopts following technical scheme, the present invention includes casing, main shaft in casing is provided with eccentric disc, eccentric disc is connected with one end of plunger case inner plunger, and the other end of plunger stretches out plunger case and is arranged in feed bin, and the end of feed bin is provided with material mould corresponding to plunger, be feed hopper above feed bin, the pressure feeding spiral with uni-drive gear box is set corresponding to feed bin in feed hopper; Pressure feeding spiral is positioned at the helical duct being communicated with feed hopper and feed bin, and it is characterized in that: described helical duct is set to up big and down small truncated cone-shaped channel, described pressure feeding spiral is that its external diameter corresponding to the shape of helical duct is up big and down small; The shape of described feed bin inner chamber is corresponding with the shape of plunger.
Beneficial effect of the present invention: 1, because the internal diameter of helical duct of the present invention is set to up big and down small truncated cone-shaped, pressure feeding spiral is the Reducing screw corresponding to the shape of helical duct; Therefore, in the process of feed, in helical duct, achieve the precommpression to material, add the feeding coal of spiral, substantially increase operating efficiency of the present invention.
2, because the shape of feed bin of the present invention is corresponding with the shape of plunger, and the inwall of feed bin fits with the outer wall of plunger; Can ensure that the material transported through pressure feeding spiral is kept in it, all be squeezed into pan feeding mould by plunger subsequently, avoid the destruction of material dead band and generation thereof.
