Description
Technical field
The utility model relates to a kind of aperture gradual change type comminutor discharging orifice plate, and in particular, the aperture that relates in particular to a kind of discharge end is greater than the aperture gradual change type comminutor discharging orifice plate in feed end aperture.
Background technology
Screw extruding granulator is the common forming machine that powder material can be manufactured to given shape, is widely used in the fields such as petrochemical industry, pharmacy, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, pottery, rubber, plastics.Comminutor can be divided into again front extruded type and side extruded type by extrusion way; wherein front extruded type has the advantages that the intensity extruded is high; discharging orifice plate is installed on this equipment discharging opening place; it is one of essential elements; perforate size, the shape of discharging orifice plate have directly determined material forming shape; in the situation that perforate size and number is certain, the thickness of discharging orifice plate directly affects the hardness of extruded material, affects the power consumption of comminutor simultaneously.Material is by orifice plate extrusion, and plate body must bear certain thrust, if plate body is blocked up, long-term use easily causes the problem such as bulk deformation, discharge opening obstruction, crosses the thin power of extruding that will cause inadequate, extrudes grain forming bad, and after orifice plate attenuation, intensity also can reduce, thereby cause modification.
Summary of the invention
The utility model, in order to overcome the shortcoming of above-mentioned technical problem, provides a kind of aperture gradual change type comminutor discharging orifice plate.
Gradual change type comminutor discharging orifice plate in aperture of the present utility model, comprises the plate body that is arranged at comminutor discharging opening place, evenly offers discharge opening on described plate body; Its special feature is: described discharge opening is greater than the aperture near feed end near the aperture of discharge end.
Discharge opening is set to be greater than the shape near feed end near discharge end aperture, reduce the contact area in material extrusion and between hole wall, also just reduced the frictional force between material particles and discharge opening, both be conducive to grain forming, be difficult for stopping up, and avoided again discharging orifice plate due to stressed excessive distortion.
Gradual change type comminutor discharging orifice plate in aperture of the present utility model, described discharge opening becomes equilateral triangle or square profile on plate body.
Gradual change type comminutor discharging orifice plate in aperture of the present utility model, described discharge opening is by 1.0～1.5 times through feed end aperture near the aperture of discharge end.The aperture of discharge end and feed end differs and is difficult for excessively, in order to avoid reduce the number of certain area discharge opening, affects discharging efficiency.
The beneficial effects of the utility model are: comminutor discharging orifice plate of the present utility model; by the discharge opening on plate body is designed to the shape that discharge end aperture is greater than feed end aperture; effectively reduce the contact area between material and hole wall; reduce the active force between material particles and discharging orifice plate; both be conducive to the moulding of particle; particle is difficult for stopping up, and has avoided again material excessive and be out of shape to the active force of discharging orifice plate, has extended the service life of discharging orifice plate.Gradual change type discharging orifice plate in aperture of the present utility model, application is given prominence to, is suitable for to simple in structure, beneficial effect.
Brief description of the drawings
Fig. 1 is the structural representation of existing comminutor discharging orifice plate;
In Fig. 2, figure a is the structural representation of the discharge opening on existing discharging orifice plate, and figure b is the structural representation of gradual change type comminutor discharging orifice plate in aperture of the present utility model.
In figure: 1 plate body, 2 discharge openings.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1; provide the structural representation of existing comminutor discharging orifice plate; on shown plate body 1, evenly offer the discharge opening 2 of some; remain consistent from feed end to the aperture of discharge end discharge opening 2; in the process process of comminutor extruded material; the material being positioned among discharge opening 2 can produce friction force f to hole wall, can produce again directed force F at feed end one side material to the region that discharge opening 2 is not set.Under the effect of frictional force f and thrust F, material can general performance be outside thrust to discharging orifice plate.
Under actual conditions, in order to make discharging orifice plate there is longer service life, be difficult for flexural deformation, discharging orifice plate generally has larger thickness, will increase like this contact area and frictional force between material particles and discharge opening 2, also easily cause material particles to stop up simultaneously.
In Fig. 2, figure a is the structural representation of the discharge opening on existing discharging orifice plate, figure b is the structural representation of gradual change type comminutor discharging orifice plate in aperture of the present utility model, because material particles frictional force size and contact area between them to inwall when locating discharge opening is directly proportional, figure a is existing discharging orifice plate, figure b is discharging orifice plate of the present utility model, in figure b, discharge opening 2 has feed end inwardly to start to become large in approximately 1/2 aperture, place, becoming large section in aperture material particles is molded can not have very strong pressure to inwall, make material particles approximately reduce half at the compression area of whole discharge opening 2, frictional force also reduces thereupon greatly, reduce the chance that material stops up in hole, but also can keep the existing thickness of discharging orifice plate constant, ensure the intensity of discharging orifice plate, extend the service life of discharging orifice plate.For non-resilient dried material, final molding effect is unaffected.
Discharge opening 2 distributes and can be designed as circle (single screw pelletizer), 8-shaped (dual-screw pelletizer) according to discharging opening shape, is equilateral triangle and distributes or square profile, and keep certain intervals to arrange between Kong Yukong.It is unsuitable excessive that the aperture size of discharge opening discharge end and feed end differs, and is 1.0～1.5 times that lean on through feed end aperture as adopted discharge opening 2 near the aperture of discharge end, in order to avoid reduce the number of certain area endoporus, affects discharging efficiency.Plate body 1 should be selected the material corrosion-resistant, tough is strong, prevents from causing brittle fracture between two holes in the time beating macropore.
Although the utility model is described in conjunction with figure above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; instead of restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; in the situation that not departing from the utility model aim, can also make a lot of distortion, within these all belong to protection domain of the present utility model.
