Abstract
The invention discloses a screw grinder, which comprises a grinding pole and a body, wherein, the body is a cavity which is provided with an interlayer and a sealing cover on the top; the grinding ball takes the shape of a screw, the teeth shape along the normal direction of which is formed by straight lines and arcs or elliptic arcs, and the bottom end is planar; the grinding pole is positioned in the body, and the top end of the grinding pole is connected with a connecting pole which protrudes out of a sealing cover; and the interlayer is a cooling water cover. When the grinding pole of the invention rotates, the arc face of the teeth exerts axial force and vertical force on the materials and the inner wall of the grinding cavity exerts fricative force on the material, therefore, the material and the grinding pole arc, the materials, and the material and the inner wall of the grinding cavity crush, press, cut and rub to finish the following work: rough particles are crushed into nanometer powder body; multiply compound powder body mixes and combines evenly; the powder body and organism or polymer media mix and combine; and the powder body undergoes solid state reaction under the function of mechanical force.
Description
Technical field
The present invention relates to grinder, particularly a kind of being used for: coarse granule is pulverized and is nano-powder; The even mixing and the combination of multicomponent powder; Powder mixes with organism or macromolecule medium and combines; Solid state reaction under the effect of powder machinery power; The screw abrasive machine of the mechanical alloying of metal-powder.
Background technology
Mechanochemical reaction is to adopt mechanical energy to activate raw material, causes the change and the new thing formation mutually of raw material structure, and the material that grinding is obtained is nano particle often.Mechanochemical reaction not only has advantages such as technology is simple, cost is low, the preparation process temperature is low, and be different from wet chemical technologies such as co-precipitation, sol-gel process, be a dry process process fully, thus little to the pollution of environment, belong to the environmental protection synthesis technique.Yet traditional high-energy ball milling machinery chemical method synthesis technique comes from mechanical alloying method, design based on shattering, mainly transmit energy by collision, exist the mechanical force time short, efficient is low, energy consumption height, shortcoming such as productive rate is low, shortcomings such as the rate of recovery is low have had a strong impact on the application of these class methods in material is synthetic.
Summary of the invention
A kind of screw abrasive machine of providing at the deficiencies in the prior art is provided, it relatively rotates by screw rod and grinding chamber, produce two kinds of extruding, increased the frictional force that reaches between the abrasive particle between abrasive and the grinding chamber wall, the abrasive particle is produced lasting powerful shearing force, with the crystal structure or the surface texture of reconstruct abrasive particle.
The object of the present invention is achieved like this:
A kind of screw abrasive machine, it comprises grinding rod, body, body which is provided with capping for the body body is provided with the cavity of interlayer; Grinding rod is a screw shaped, and its normal direction profile of tooth is straight line and circular arc or elliptic arc formation, and the bottom is the plane; Grinding rod is located in the body, its top is connected with connecting rod, and connecting rod stretches out capping.
The pitch of described grinding rod is 0.2～5: 1 with the screw diameter ratio.
Described body body body one side is provided with water inlet, delivery port, and the slit is 0.5～2.0 millimeter between cavity in the body and the grinding rod; Described interlayer is a cooling jacket.
Described capping is provided with air inlet, gas outlet.
When grinding rod of the present invention rotates, axial thrust load, radial component and grinding chamber inwall that the cambered surface of its tooth produces material are to the frictional resistance that material produces, and make between material and grinding rod cambered surface, material and material and material and the grinding chamber inwall to bump, push, shear, rub and finish following work: the coarse granule pulverizing is a nano-powder; The even mixing and the combination of multicomponent powder; Powder mixes with organism or macromolecule medium and combines; Solid state reaction under the effect of powder machinery power.
Owing to can produce a large amount of heat in process of lapping, the present invention to absorb the heat that wherein produces, avoids high temperature to the additional cooling jacket of grinding chamber.
Grinding chamber of the present invention is a ventilated atmosphere of bringing pore and venthole into, and the obturator of vacuum-pumping helps the solid state reaction to needing controlled atmospher to carry out, as nitrogenize, oxidation, reduction, decompose, can promote the carrying out that react by feeding corresponding atmosphere or vacuumizing.
