Abstract
The utility model discloses a screw grinder, which consists of a grinding rod and a grinder body. The body of the grinder body is provided with an interlining cavity, on which a seal cap is arranged; the grinding rod is screw-shaped, the normal direction tooth form of which is composed of straight lines and circular arcs or elliptic arcs and the bottom end of which is a plane; the grinding rod is arranged in the grinder body, the top end of which is connected with a connecting bar; the connecting bar extends out of the seal cap; the interlining is a cooling jacket. When the grinding rod of the utility model rotates, the axial thrust load, the radial thrust load generated on the material by the arc surface of the teeth and the friction drag generated on the material by the inner wall of a grinding cavity lead the material and the grinding rod arc surface, the material and the material, the material and the grinding cavity inner wall to impact, extrude, cut and scrub, thus completing the following operations: coarse granules are ground to be nano powder; powder of a plurality of components are evenly mixed and combined; powder and organism or macromolecular media are mixed and combined; solid phase chemical reaction is carried out under the effect of powder mechanical force.
Description
Technical field
The utility model 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
The purpose of this utility model is a kind of screw abrasive machine that provides at the deficiencies in the prior art, 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 purpose of this utility model is achieved in that
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 the utility model grinding rod 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 utility model to absorb the heat that wherein produces, is avoided high temperature to the additional cooling jacket of grinding chamber.
Grinding chamber of the present utility model 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.
