Description
Technical field
The present invention relates to the improvement of mortar, be specifically related to a kind of mortar.
Background technology
Mortar is the conventional container of milled solids material in experiment, is furnished with alms bowl pestle (or claiming alms bowl hammer), and for abrasive solid material or carry out the mixed of pulverulent solids, the size of its specification bore represents.Conventional is ceramic products, and mortar also has the goods of glass, Achates, aluminium oxide, ferrum, and these mortars used of a specified duration, it is easy to damaged so that produce impurity in material.
Mortar conventional in the market, due to flatter bottom bowl, bowl is made to contact defective tightness with alms bowl hammer, contacting of the some dough-making powder a bit and between the inner surface of bowl that usually alms bowl is hammered into shape, bowl is less with the contact area of alms bowl hammer, material to grind and to be lot more time to produce a desired effect, and grinding efficiency is low.
Summary of the invention
Low in order to solve existing mortar grinder efficiency, labor intensity is big, and process of lapping produces the shortcoming of impurity, and the present invention provides a kind of mortar.Mortar shape provided by the invention and structure are ingenious, and grinding efficiency is high, time saving and energy saving, it is adaptable to abrasive solid powder or slurry.It addition, mortar provided by the invention adopts highly purified corundum material, process of lapping will not produce impurity, contaminated material.
In order to solve above-mentioned technical problem, the present invention adopts following technical proposals:
A kind of mortar, described mortar includes bowl and alms bowl hammer, and described alms bowl hammer includes tup and hammer handle, and the bottom surface of described tup is hemispherical；Described bowl comprises circular orbit, and the cross section of the bottom of described circular orbit is semicircle；This rail base semi circular surface coordinates with the semi circular surface of tup bottom surface.
Described circular orbit is round circular orbit.
Further, described bowl includes bowl wall, is conformed with in the middle part of described bowl, forms described circular orbit between described bowl wall inner surface and described projection outer surface；Described tup is spherical；The bottom of described round circular orbit is the curved surface of concave downward, and the cross section of described curved surface is semicircle.
Lower half sphere of spherical tup of above-mentioned alms bowl hammer closes with the semicircular base matching form of described round circular orbit.Preparation process utilize corundum grind, prepare the semicircle curved surface bottom high-precision leakproof fit spherical tup and round circular orbit, in process of lapping, filling 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 serves abrasive action entirely.
Preferably, the semicircular radius of the cross section bottom described circular orbit is R2, the radius of described spherical tup is R1, R2-R1Range for 0.01-0.5mm.R2-R1Difference be 0.01mm, 0.05mm, 0.1mm, 0.2mm, 0.3mm, 0.4mm, 0.5mm.Preferably, R2-R1=0.1-0.5mm。
Projection in the middle part of bowl can be avoided in process of lapping, and material concentrates on the middle part of bowl, affects grinding efficiency.The curved cross section of the bottom of described round circular orbit is semicircle so that the bottom of described round circular orbit is suitable with half sphere of described spherical tup, increases the contact probability of alms bowl hammer and bowl inner surface in process of lapping.Described curved surface is less with the gap of described spherical tup, further increases the contact probability of alms bowl hammer and bowl inner surface.Therefore, the curved surface bottom bowl increases the contact area of alms bowl hammer and bowl, and then increases milling area, improves 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, alms bowl hammer is more big with the contact area of bowl, and milling area is more big, and grinding efficiency is more high.The requirement that can reach according to the particle diameter of the material ground, determines R2With R1Difference.The particle diameter of the material after grinding is more little, R2With R1Difference more little.
Preferably, the cross section of described circular orbit is U-shaped.
Preferably, described projection is cylindrical, and the outer surface of the bottom of described projection is smooth curved surface, and the inner surface of the bottom of described bowl wall is smooth curved surface, and two curved surfaces are connected and form the bottom of described round circular orbit.
It is further preferred that described projection is cylindrical, described cylindrical projections is contour with bowl wall.
Described bowl and alms bowl hammer are made up of high-abrasive material.High-abrasive material includes high-purity corundum (also known as wear-resistant ceramic), carborundum, abrasion-resistant stee etc..
Further, the material of described bowl and alms bowl hammer is corundum, and described corundum is high-purity corundum；Al in described corundum2O3Content be 86-100%.Preferably, Al in described corundum2O3Content be 90%, 95%, 98%, 99%, it is most preferred that, Al in described corundum2O3Content be more than 99%.
Compared with prior art, mortar provided by the invention adopts corundum material, and process of lapping will not produce impurity, pollutes the material of processing；And mortar shape and structure are ingenious, coordinating between bowl with alms bowl hammer is accurate, make alms bowl hammer and contact, between material, the way of contact being become face dough-making powder from the way of contact originally putting dough-making powder, the area being used for grinding between alms bowl hammer and material increases, and then improve grinding efficiency, time saving and energy saving, and, the fineness of the pressed powder being ground reaches 1-50um, even higher fineness.On the other hand, mortar provided by the invention can coordinate motor drive mechanism to carry out mechanical lapping.
