Description
Technical field
The present invention relates to the milling apparatus of medicine, be specially a kind of stagewise lapping device.
Background technology
In pharmaceutical industry, re-use after the needs that the raw material producing medicine have grind.Existing lapping device is all generally directly raw material are ground to pulverulence from graininess; when raw-material grain diameter has multiple specification; if ground simultaneously; the particle that particle diameter is large can be played a supporting role to lapping device; the little particle of particle diameter can pass from the gap formed between the large particle of particle diameter; thus the particulate abrasive making particle diameter little is insufficient, needs repeatedly to repeat grinding and just can meet the demands, make production efficiency low.
Summary of the invention
The object of this invention is to provide a kind of stagewise lapping device, easily produce the insufficient problem of grinding to solve when the material particles of different-grain diameter grinds together in prior art.
To achieve these goals, a kind of stagewise lapping device provided by the invention, comprise the rotating cylinder vertically arranged, the inside of rotating cylinder is provided with the fixed axis of coaxial line, grinding mechanism is provided with between fixed axis and rotating cylinder, grinding mechanism comprises dynamic mill part and surely grinds part, the shape of surely grinding part is tapered, surely mill part and fixed axis are coaxially arranged, surely grind part to be sheathed on fixed axis and to be fixedly connected with fixed axis, surely grind between part and rotating cylinder and be provided with material channel, the shape of dynamic mill part is tapered, the inside of dynamic mill part is provided with and the conical cavity determined mill part and match, dynamic mill part is fixedly connected with rotating cylinder, the top of dynamic mill part is provided with charging aperture, the top of dynamic mill part is provided with funnelform material guiding hopper, the vertical projection face of material guiding hopper is greater than the vertical projection face of determining mill part, material guiding hopper is provided with sieve aperture, described grinding mechanism is provided with multiple, dynamic mill part and the grinding gap of surely grinding between part reduce gradually from top to bottom.
Multiple grinding mechanism comprising dynamic mill part and surely grind part is set; the top of surely grinding part is stretched in the conical cavity of dynamic mill part; by the rotation of dynamic mill part; make mill part and surely grind between part to produce frictional force; and the grinding gap of grinding mechanism reduces gradually from top to bottom; during use; the particle diameter of the material particles meeting less than grinding gap enters next layer of grinding mechanism by this layer of grinding mechanism rapidly; the particle that particle diameter is larger than grinding gap can be polished the particle that mechanism grinds to form small particle diameter, and grinding mechanism can be ground the particle of different-grain diameter simultaneously.The mill part of determining of grinding mechanism is arranged to taper with dynamic mill part, and be convenient to after material particles grinding, material particles moves down under the effect of deadweight.At the top of dynamic mill part, funnelform material guiding hopper is set; and the vertical projection face of material guiding hopper is greater than the vertical projection face of determining mill part; the particle ground through upper strata grinding mechanism can fall into material guiding hopper, is imported in this layer of grinding mechanism by material guiding hopper, thus realizes automatically turning material.
Operation principle: start drum rotation, material particles is put into the material guiding hopper at top, enter the grinding mechanism of the superiors, the meeting that the particle diameter of material particles is less than grinding gap passes through this layer of grinding mechanism rapidly, and drop in the material guiding hopper of lower one deck grinding mechanism, the particle that particle diameter is larger than grinding gap can be ground into the particle of small particle diameter under dynamic mill part and the rubbing action in relative rotation of surely grinding part, then drop to the material guiding hopper of lower one deck grinding mechanism from the surrounding determining mill part, the grinding gap of lower one deck grinding mechanism is less than the grinding gap of upper strata grinding mechanism, from and can grind than self large material in grinding gap the particle diameter of material particles, repeat said process, to the last obtain the qualified material of particle diameter.
Compared with prior art, the advantage of this programme is: by once feeding in raw material, and lapping device carries out screening grinding to grain diameter voluntarily, and the particle of different-grain diameter to there being different grinding mechanisms, thus avoids material particles and grinds insufficient problem.
Further, described material guiding hopper is provided with sieve aperture, and the aperture size of sieve aperture is identical with the width in the grinding gap of the grinding mechanism that the material guiding hopper at its place is connected.When material particles is through material guiding hopper, the particle that particle diameter is less than grinding mechanism grinding gap can directly enter the grinding mechanism of lower one deck through sieve aperture, thus decrease small size particle by during grinding mechanism to the inhibition that large-size particles is formed.
Further, the suitable for reading of described material guiding hopper is fixedly connected with rotating cylinder.Be conducive to material guiding hopper and better bear the impulsive force that top material particles falls down, strengthen the stability of material guiding hopper.
Further, support bar is provided with between the top of described dynamic mill part and rotating cylinder.When grinding material, material can produce thrust to dynamic mill part, and by arranging support bar, the thrust of material is better born on the top being conducive to dynamic mill part, makes the structure of grinding part more stable.
Further, the outer wall of described rotating cylinder is provided with reinforcement.Rotating cylinder is when rotating, and cylindrical shell can bear larger torsion, by arranging reinforcement on barrel, being conducive to the anti-twisting property strengthening rotating cylinder, improving the stability of rotating cylinder.
Further, the below of described rotating cylinder is provided with spiral feeder, and feeder is fixedly connected with fixed axis.Be convenient to material be led one and export discharging.
