Background technology
Powder metallurgy be produce metal or with metal dust (or mixture of metal dust and non-metal powder) as raw material, through being shaped and sintering, manufacture the technology of metal material, composite and all kinds goods.Powder metallurgic method has similar place to production pottery, and therefore, a series of New Technologies In Powder Metallu Rgy also can be used for the preparation of ceramic material.Due to the advantage of PM technique, it has become the key solving new material problem, plays a part very important in the development of new material.
In the preceding working procedure of powder metallurgy, after with the addition of the materials such as paraffin, rubber, machine oil and plasticizer, fully be uniformly mixed into the powder ball of similar plasticine, then carry out extruding slivering to it to be granulated by cutting, eventually pass hot blast etc. to blow, dry, so that follow-up, the pellet of multiple batches is carried out mixed batch, mass discrepancy between checkmating batch, pellet conveniently can enter mould and carries out shaping simultaneously.In prior art, the production efficiency of prilling granulator is too low, can not meet the needs of large-scale production.
Summary of the invention
The utility model overcomes the deficiencies in the prior art, provides a kind of structure simple taper direct-insert powder compacting prilling granulator.
For achieving the above object, the technical solution adopted in the utility model is: a kind of taper direct-insert powder compacting prilling granulator, comprise: material extrusion tank, and the cover cone be arranged in material extrusion tank, described cover cone comprises being arranged on outer fieldly extrudes cone and the cutting cone of internal layer, the major part downwardly facing opening of described cover cone is arranged, it is characterized in that, described extruding on cone is placed with extrusion cavities, described extrusion cavities is arranged into several horizontal casts described extruding on cone, cutting cone is provided with several grid circles, the corresponding horizontal loop in the equal position of each described grid circle, described cutting cone can relatively be extruded coning along its axis and turn.
In the utility model preferred embodiment, described grid circle is provided with the alternate grid hole that is provided with and grid bar, and the grid hole quantity on each grid circle is all identical with the extrusion cavities quantity on corresponding horizontal loop.
In the utility model preferred embodiment, described material extrusion tank is provided with binder mouth, and described binder mouth is tightly connected screw extruder.
In the utility model preferred embodiment, described cutting cone top connecting drive device, described drive unit can drive cutting cone relatively described in extrude coning and turn.
In the utility model preferred embodiment, described in extrude cone together with described cutting cone squeezed tight.
In the utility model preferred embodiment, described extrusion cavities is square or circular.
In the utility model preferred embodiment, described material extrusion tank and describedly extrude between cone except extrusion cavities, other position seals are arranged.
The utility model solves the defect existed in background technology, and the utility model material extrusion tank passes through the material constantly clamp-oned, and makes the interior pressure that its inner generation is larger, expects to be extruded into strips by from extrusion cavities, is cut into granular at cutting tank and the relative motion of extruding tank generation; Because grid circle is corresponding with horizontal loop position, the strip material entered in grid hole just can be periodically cut-off, and granular length can regulate; Drive unit is provided with up and can not has influence on granulation work.

Detailed description of the invention
Be described in further detail the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As Figure 1-4, a kind of taper direct-insert powder compacting prilling granulator, comprise: material extrusion tank 1, and the cover cone 3 be arranged in material extrusion tank 1, cover cone 3 comprises and is arranged on the outer field cutting cone 7 extruding cone 4 and internal layer, the major part downwardly facing opening of cover cone 3 is arranged, extrude on cone 4 and be placed with extrusion cavities 5, extrusion cavities 5 is arranged into several horizontal casts extruding on cone 4, cutting cone 7 is provided with several grid circles, the corresponding horizontal loop in the equal position of each grid circle, cutting cone 7 can rotate along its axis relative to extruding cone 4.
Material extrusion tank 1 passes through the material constantly clamp-oned, and makes the interior pressure that its inner generation is larger, expects to be extruded into strips by from extrusion cavities 5, is cut into granular at cutting tank and the relative motion of extruding tank generation; Because grid circle is corresponding with horizontal loop position, the strip material entered in grid hole 8 just can be periodically cut-off, and granular length can regulate; Drive unit 10 is provided with up and can not has influence on granulation work.
Grid circle is provided with the alternate grid hole 8 that is provided with and grid bar 9, and grid hole 8 quantity on each grid circle is all identical with extrusion cavities 5 quantity on corresponding horizontal loop, and such design makes the material of strip can be cut into pellet uniformly, and granulation is more even.The interval of grid bar 9 and grid hole 8 is arranged and the lateral length of each grid hole 8 can specify the length of pellet.
Material extrusion tank 1 is provided with binder mouth 2, and binder mouth 2 is tightly connected screw extruder 11.Material can mix by screw extruder 11 fully, then for extruding tank provides sufficient pressure, ensures the smooth of material slivering.
Cutting cone 7 top connecting drive device 10, drive unit 10 can drive cutting cone 7 to rotate relative to extruding cone 4, cutting cone 7 active rotation, can cut into granular to extruding the billot that cone 4 extrudes.
Extrude cone 4 together with cutting cone 7 squeezed tight, such working angles does not have material and is mixed into and extrudes between cone 4 and cutting cone 7, and impact rotates relatively, and it is more accurate to make to cut simultaneously.
Extrusion cavities 5 is square or circular, and the pellet shape of cross section cut out like this can be controlled, and pellet that is square or circular cross sectional shape can be applicable to the billot density forming requirements of different die molding machines.
Material extrusion tank 1 and extrude between cone 4 except extrusion cavities 5, other position seals are arranged, and such extruding force all can focus on extrusion cavities 5 place.
Above according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related personnel in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine technical scope according to right.
