Description
Technical field
The utility model relates to stalk granular fuel production equipment, particularly relates to a kind of Novel grinding being applicable to flat-die rolling former and rushes roller.
Background technology
Living beings are widely distributed on earth, inexhaustible.China's agricultural crop straw annual production about 7.2 hundred million tons, this is a huge energy reserves, but its effective rate of utilization is less than 30%, living beings are as the energy, there is energy density little, come in every shape, transport inconvenience, use procedure can not facilitate, cleanly realize power conversion, to store and use takes up room and the shortcoming such as to have greatly, become " bottleneck " that the scale of restriction living beings utilizes, biomass moulding technology is the effective ways solving this " bottleneck ", biomass moulding is exactly become to have certain density by loose biomass processing, the goods of shape, goods are used as fuel, the controllability of its burning and the convenience of use, fuel oil can be reached, the level of combustion gas, be used for warming oneself as coal, cooking, direct combustion power generation etc., there is the heat of medium moulded coal.
The research and development of biomass solid shaping technology and equipment mainly contains both at home and abroad at present: the bar-shaped forming technique that the screw extrusion mode that Japan develops is produced; The piston-type extrusion strip forming technique of European Countries exploitation; The interior pressure roller graininess forming technique of American R & D.Spiral squeezing type and crank piston punch forming thing density slightly low, easily loose, and can not continuous seepage, it is large all to there is energy consumption in above-mentioned two kinds of equipment, and main part is easy to wear, and the life-span is lower, and average life span 60 ~ 80 hours, considerably increases the cost of biomass solid shaping.
China's many employings ring mould roller rolls and flat-die rolling production method.These two kinds of method continuitys are extruded, and the rate that comes into force is higher, because living beings are primarily of fiber and lignin composition, its mobile performance is poor, so living beings are easily by the taper hole blocking on flat-die in roller compaction process, particle cannot be extruded from taper hole, causes milling roller to skid, produce amount of heat, whole equipment failure, on the basis of original milling roller, designs a kind of Novel grinding and rushes roller, improve the mobility of living beings, enhance productivity.
Utility model content
The utility model is poor for living beings mobile performance, so the taper hole on flat-die easily blocks by living beings in roller compaction process, particle cannot be extruded from taper hole, milling roller is caused to skid, produce amount of heat, the problem of whole equipment failure, proposes a kind of Novel grinding being applicable to flat-die rolling former and rushes roller.
In order to solve the problem, the utility model adopts following technical scheme:
A kind of Novel grinding being applicable to flat-die rolling former rushes roller, comprise flat-die, round roller is overall, the periphery of described round roller is provided with body cover, described body cover dimidiation, protruding round platform is established on body cover surface, the shape of described protruding round platform and position is corresponding with the forming hole on flat-die arranges, the central through hole of round roller penetrates axle, and the surrounding at the center of round roller is provided with screw.
Further, in order to have good elasticity and wearability, higher mechanical strength and hardness, described body cover is polyurethane elastomer cover.
Further, after being convenient to production loss, more ring keeps in repair, and described body cover is fixed by screws in round roller.
Further, described round roller adopts metal material.
Compared with prior art, the utility model tool has the following advantages: the coated polyurethane elastomer of punching press roller circumference, alleviates the protruding stamping press produced when colliding with shaping taper hole, decrease to flat-die wearing and tearing; Destroy in forming process and be rolled into sheet obstruction taper hole, promote the flowing of living beings; Ensure that particle is adequately compressed, enhance productivity, reduce energy consumption.

Fig. 2 is the left view of punch roll.
Fig. 3 is that punch roll circumference launches schematic diagram.
Fig. 4 is protruding round platform enlarged drawing.
Detailed description of the invention
Below in conjunction with accompanying drawing, further concrete implementation is done to the utility model:
As Fig. 1,2, shown in 3 and 4, a kind of Novel grinding being applicable to flat-die rolling former rushes roller, comprise flat-die, round roller 1 is overall, and the periphery of described round roller 1 is provided with body cover 2, and described body overlaps 2 dimidiations, body overlaps 2 surfaces and establishes protruding round platform 3, the shape of described protruding round platform 3 and position is corresponding with the forming hole on flat-die arranges, the central through hole of round roller 1 penetrates axle, and the surrounding at the center of round roller 1 is provided with screw 4; Described body cover 2 is polyurethane elastomer cover; Described body cover 2 is fixed by screws in round roller 1; Described round roller 1 adopts metal material.
Stone roller rushes roller entirety for cylindric, the coated polyurethane elastomer cover 2 of circumference, it is by necessarily regularly arranged protruding round platform 3 that polyurethane elastomer overlaps 2 surface design, the size of these protruding round platforms 3 is identical with the conical through-hole on flat-die, location dimension is identical with the shaping taper hole on flat-die, revolve round the sun and spinning motion under the drive of feathering axis, the shaping taper hole ensured on protruding round platform 3 insert continually flat-die is calculated through rotating speed and size design, insert taper hole by protruding round platform 3 to realize carrying out punching press to the living beings of the preliminary bonding rolled, accelerate stalk to be extruded further by the forming hole on flat-die, destroy milling roller above simultaneously and roll the covering of caused stalk to taper hole, increase the mobility of stalk, prevent taper hole blocked, polyurethane elastomer cover 2 has good elasticity and wearability, higher mechanical strength and hardness, protruding little with impulsive force in forming hole punching course, reduce the vibratory impulse of whole equipment, reduce the wearing and tearing to flat-die forming hole simultaneously, polyurethane elastomer cover 2 is split into two halves, be fixed by screws in metal round roller, after being convenient to production loss, more ring keeps in repair.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
