Description
Technical field
The utility model relates to a kind of module, relates in particular to a kind of single lead screw ex truding briquetting machine module that is used for the band nib of biomass compact forming.
Background technology
At present, energy scarcity is on the rise, and meanwhile, contain the idle waste of biomass resources such as stalk, branch of big energy, and on-site incineration causes environmental pollution, influences traffic safety, has serious disaster hidden-trouble.Single lead screw ex truding briquetting machine is born under this background, and from present situation both domestic and external, research is set about early in the European and American areas, technology is ripe relatively, but apparatus expensive, the operating cost height, cause the briquetting product price height produced, introducing overseas equipment does not have the market advantage.Simultaneously, the crop of different regions is because of geographical environment, weather difference, the growth cycle difference, cause the extrusion performance of zones of different crop material widely different, especially as straw, wheat straw etc., and the material of the Northeast is difficult to extrusion modling, and main cause is that present single lead screw ex truding briquetting machine compression ratio is not enough, squeezing effect is undesirable, and this has just limited the scope of application of single lead screw ex truding briquetting machine greatly.
The utility model content
In order to overcome the above-mentioned defective of prior art, the utility model provides a kind of single lead screw ex truding briquetting machine module, described module compression ratio is big, simple in structure, be convenient to make and installing/dismounting, adopt the single lead screw ex truding briquetting machine of this module, good to squeezing effects such as straw, wheat straws, also can well push the stalk of the Northeast.
The technical solution adopted in the utility model: a kind of single lead screw ex truding briquetting machine module, be block, modular structure left-right symmetry and symmetrical up and down, its cross section outer contour shape is the fan annular, is provided with the groove along sidewall of symmetry at the middle part of its thickness direction.
The cross sectional shape of described module groove is along the change in radius of fan annular, and the full-size of each cross section of groove on thickness direction equates, this size all with fan annular side wall surface coplane.The groove cross sectional shape is divided into three parts, and its leading portion is the square-section for the through hole about connecting.The centre of groove excessively section cross section is a rectangle, and internal face leaves the processing fillet.The back segment cross section of groove is vertical semicircle, and section radius equates.
The center of circle of described fan annular overlaps with the corresponding mould center of circle, its central angle is 360 ° of angles that divide exactly or is the 360 ° of angle that divides exactly ± 5 °, thus, a plurality of described modules closely can be arranged on the circumference of mould, form annular, make the squeegee roller of winding mold dish revolution can just be installed in the inner chamber of the annular that surrounds; After module was closely arranged, groove on each module and the groove on the adjacent block were spliced to form extrusion die orifice, and front end forms the bigger charging aperture in space, and the rear end forms circular nib.Running by squeegee roller is pressed into material in the nib.
Can be provided with a vertical through hole through integral body on the thickness direction of described module, so that module is fixedly mounted between the upper and lower die cap of mould, this through hole does not penetrate groove, in order to avoid influence the discharge of pressing materials.
The beneficial effects of the utility model: it is the rectangle charging aperture that the utility model adopts the nib leading portion, back segment is circular extruded segment, its compression ratio is big, effective to present conventional material forming, to material such as the also extrusion mo(u)ldings preferably such as straw, wheat straw and the Northeast's material that are difficult to push, strengthened the adaptability of equipment; This utility model volume is little, simple in structure, is easy to make, in case be damaged, only needs the dismounting and change single-piece to get final product; In addition, when needs change the nib shape, only need to change a whole set of module, other structures all need not to change and just can continue to use.

The specific embodiment
Referring to Fig. 1～6, the utility model provides a kind of single lead screw ex truding briquetting machine module, is block, modular structure left-right symmetry and symmetrical up and down, and module cross section outer contour shape is the fan annular, is provided with the groove along sidewall of symmetry at the middle part of its thickness direction.Thickness direction can be provided with one and runs through whole vertical through hole 1 on module, is used for module is fixedly mounted between the upper and lower die cap of mould of extrusion modling, and this through hole 1 does not penetrate nib, in order to avoid influence the discharge of pressing materials.
In order to make the module close arrangement between upper and lower die cap, form circular nib, and during the squeegee roller revolution material is squeezed into each nib uniformly, after assembly unit is finished, the center of circle of the fan annular of module cross section outer contour shape overlaps with the center of circle of mould, central angle can or be the 360 ° of angle that divides exactly ± 5 ° for 360 ° of angles that divide exactly, and whether according to needs gap and gap length are determined.
The size of the central angle of module and mold hole dimension size can guaranteeing under module strength, the prerequisite in life-span nib to be set as much as possible, improve efficiency of equipment according to the size adjustment module of required briquetting and the size of groove.
The utility model is simple in structure, and volume is little, is easy to make, and interchangeability is strong, and easy accessibility when having only a certain or certain several module wear and/or when destroying, need only be changed corresponding module and just can continue to use, and has improved the utilization rate of equipment.When needing the briquetting product of higher density, this module more has superiority.
