Abstract
A kind of silicon carbide micro-powder shredder assemblies, including rotary grinding disk and fixed millstone are the utility model is related to, processing material chamber is equipped with rotary grinding disk and fixed millstone, the processing material intracavitary of rotary grinding disk has an annular convex platform；Material casting groove is equipped with annular convex platform；There is gap between the processing material chamber for the rotary grinding disk being oppositely arranged and the processing material chamber of fixed millstone；Wherein positioned at the processing material chamber triangle cavity type structure in a ring of the annular convex platform side.The utility model can be rotated therewith all materials into mill by the design of rotary grinding disk upthrow hopper；By the material casting effect of material casting groove and the constraint pressurization of annular convex platform, laminated grinding function of the material in processing material intracavitary circumferentially normal direction is realized；By to processing material chamber structure design, increase the compactness between material particles, pressure it is big, generate shear action and shearing stress in the faying face of storeroom so that material can be crushed thinner.
Description
Technical field
It the utility model is related to a kind of shredder assemblies, and in particular to a kind of silicon carbide micro-powder shredder assemblies, belong to carborundum
Micro-powder graded technical field.
Background technology
Carborundum has stable chemical performance, and thermal conductivity factor is high, and thermal coefficient of expansion is low, and hardness is high, wearability and self-sharpening
The features such as strong, be widely used in the processing industry such as hard alloy and optical glass.In recent years, with the hair of world semiconductor industry
Exhibition, carborundum are used widely in monocrystalline silicon, polysilicon, the multi-wire saw of piezoelectric quartz crystal and grinding, especially exist
It is even more so in the photovoltaic industry of high speed development.Its quality is not only related with its purity, but also related with its grain fineness, its is pure
Degree is higher, its thinner application quality of particle is higher, and application range is wider.And traditional production method can only produce 10 μm or so
Product, and particle diameter distribution is too big, and particle is uneven, and impurity is more.
Utility model content
In view of the shortcomings of the prior art and problem, the utility model provide a kind of essence that can improve silicon carbide micro-powder
The silicon carbide micro-powder shredder assemblies of fineness and quality.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of silicon carbide micro-powder shredder assemblies, including
Rotary grinding disk and the fixed millstone being oppositely arranged with the rotary grinding disk, are equipped with processing material chamber on rotary grinding disk and fixed millstone,
The processing material intracavitary of the rotary grinding disk has an annular convex platform；It is equipped with the annular convex platform and is communicated with the processing material chamber
Material casting groove；The processing material chamber of the rotary grinding disk and fixed millstone is oppositely arranged, in adding for the rotary grinding disk being oppositely arranged
There is gap between labor and materials chamber and the processing material chamber of fixed millstone；Wherein it is located at the processing material chamber of the annular convex platform side in a ring
Triangle cavity type structure.
Further improved as the utility model, the processing material chamber for the fixed millstone being oppositely arranged with the annular convex platform is
Conical bores；The annular convex platform upper surface is equipped with the slope to match with the conical bores.
It is further improved as the utility model, the mill face formed between the rotary grinding disk and fixed millstone perpendicular to
Horizontal plane.
It is further improved as the utility model, the end face angle of the annular triangle cavity type structure is 30 °~
45°。
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
The silicon carbide micro-powder shredder assemblies of the utility model, by the design of rotary grinding disk upthrow hopper, can incite somebody to action
All materials into mill rotate therewith；It is real by the material casting effect of material casting groove and the constraint pressurization of annular convex platform
Laminated grinding function of the material in processing material intracavitary circumferentially normal direction is showed；By the structure design to processing material chamber, make
Compactness between material particles increases, pressure is big, generates shear action and shearing stress in the faying face of storeroom so that material
It can be crushed thinner.
Brief description of the drawings
Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：
Attached drawing 1 is the structure diagram of the silicon carbide micro-powder shredder assemblies of the utility model；
In figure：1- rotary grinding disks；2- fixed millstones；3- processing material chambers；4- annular convex platform；5- material casting grooves；6- gaps；7- annulars
Triangle cavity type structure；8- slopes.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of silicon carbide micro-powder shredder assemblies described in the utility model as shown in Figure 1, including rotary grinding disk 1 and with
The fixed millstone 2 that rotary grinding disk 1 is oppositely arranged, is equipped with processing material chamber 3 on rotary grinding disk 1 and fixed millstone 2, rotary grinding disk 1
Processing material intracavitary has an annular convex platform 4；The material casting groove 5 communicated with the processing material chamber 3 is equipped with annular convex platform 4；Material casting
The design of groove 5, can rotate therewith all materials into mill；Pass through the material casting effect of material casting groove and annular convex platform
Pressurization is constrained, realizes laminated grinding function of the material in processing material intracavitary circumferentially normal direction.
The processing material chamber of rotary grinding disk 1 and fixed millstone 2 is oppositely arranged, in the processing material chamber for the rotary grinding disk 1 being oppositely arranged
There is gap 6 between the processing material chamber of fixed millstone 2；Wherein positioned at the processing material chamber in a ring three of 4 side of annular convex platform
Angle cavity type structure 7；The processing material chamber for the fixed millstone 2 being oppositely arranged with annular convex platform 4 is conical bores；The annular convex platform
Upper surface is equipped with the slope 8 to match with the conical bores.By the structure design of above-mentioned processing material chamber, make material
The compactness of intergranular increases, pressure is big, and shear action and shearing stress are generated in the faying face of storeroom so that material can be by
Crush thinner.
The mill face formed between rotary grinding disk 1 and fixed millstone 2 is perpendicular to horizontal plane, the end of annular triangle cavity type structure
Face angle is 35 °, obtains the fineness and quality of optimal silicon carbide micro-powder.
It the above is only the concrete application example of the utility model, do not form any limit to the scope of protection of the utility model
System.All technical solutions formed using equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
