Description
Technical field
The utility model relates to the improvement of mortar, is specifically related to a kind of mortar.
Background technology
Mortar is to grind the container commonly used of solid material in experiment, is furnished with alms bowl pestle (or claiming the alms bowl hammer), is used for the abrasive solid material or carries out the mixed of pulverulent solids, and its specification represents with the size of bore.Commonly used is ceramic products, and mortar also has the goods of glass, agate, aluminium oxide, iron, and these mortars used of a specified duration, easily damaged, makes and produces impurity in material.
The mortar of commonly using in the market, because alms bowl body bottom is more smooth, make the alms bowl body contact defective tightness with the alms bowl hammer, normally on alms bowl hammer a bit with the inner surface of alms bowl body between point and the contacting of face, the contact area of alms bowl body and alms bowl hammer is less, material will grind for a long time and just can produce a desired effect, and grinding efficiency is low.
Summary of the invention
Low in order to solve existing mortar grinding efficiency, labour intensity is large, and process of lapping produces the shortcoming of impurity, the invention provides a kind of mortar.Mortar shape provided by the invention and structure are ingenious, and grinding efficiency is high, and is time saving and energy saving, is applicable to abrasive solid powder or slurry.In addition, mortar provided by the invention adopts highly purified corundum material, and process of lapping can not produce impurity, contaminated material.
In order to solve the problems of the technologies described above, the present invention adopts following technical proposals:
A kind of mortar, described mortar comprise alms bowl body and alms bowl hammer, and described alms bowl hammer comprises tup and hammer handle; Described tup is spherical tup, and the bottom surface of described tup is hemispherical; Described alms bowl body comprises the alms bowl body wall, described alms bowl body middle part is provided with projection, described projection is cylindrical, the outer surface of the bottom of described projection is level and smooth curved surface, the inner surface of the bottom of described alms bowl body wall is level and smooth curved surface, forms circular orbit (i.e. two curved surfaces be connected form the bottom of described circular orbit) between described alms bowl body wall inner surface and described projection outer surface; The bottom of described circular orbit is the curved surface to lower recess, and described circular orbit is round circular orbit, and the curved surface cross section of the bottom of described round circular orbit is semicircle, makes half sphere of the bottom of described round circular orbit and described spherical tup suitable.
Lower half sphere of the spherical tup of above-mentioned alms bowl hammer matches with the semicircular base shape of described round circular orbit.Utilize diamond dust to grind in preparation process, make the semicircle curved surface of high-precision leakproof fit spherical tup and round circular orbit bottom, in process of lapping, fill full with substance between the semicircle curved surface of lower half sphere of tup and the bottom of round circular orbit, lower half sphere of tup has played abrasive action entirely.
Preferably, the semicircular radius of the cross section bottom described circular orbit is R
2, the radius of described spherical tup is R
1, R
2-R
1Scope be 0.01-0.5mm.R
2-R

The projection at alms bowl body middle part can be avoided in process of lapping, and material concentrates on the middle part of alms bowl body, affects grinding efficiency.The curved surface cross section of the bottom of described round circular orbit is semicircle, make the bottom of described round circular orbit suitable with half sphere of described spherical tup, has increased the contact probability of alms bowl hammer and alms bowl body inner surface in the process of lapping.The gap of described curved surface and described spherical tup is less, has further improved the contact probability of alms bowl hammer with alms bowl body inner surface.Therefore, the curved surface of alms bowl body bottom has increased the contact area of alms bowl hammer with the alms bowl body, and then has increased milling area, has improved grinding efficiency.The gap inner stuffing material of the curved surface of the bottom of round circular orbit described in process of lapping and described spherical tup, the alms bowl hammer is larger with the contact area of alms bowl body, and milling area is larger, and grinding efficiency is higher.R is determined in the requirement that can will reach according to the particle diameter of the material that grinds
2With R
1Poor.The particle diameter of the material after grinding is less, R
2With R
1Difference less.
Preferably, the cross section of described circular orbit is U-shaped.
Further preferred, described cylindrical projections and alms bowl body wall are contour.
Described alms bowl body and alms bowl hammer are made by high-abrasive material.High-abrasive material comprises high-purity corundum (claiming again wear-resistant ceramic), carborundum, abrasion-resistant stee etc.
Further, the material of described alms bowl body and alms bowl hammer is corundum, and described corundum is the high-purity corundum; Al in described corundum
