Abstract
The invention discloses a secondary air inlet ultrafine grinding device for grinding traditional Chinese medicines. In the grinding process, when coarse particles fall, secondary inlet air is led in for conducting further elutriation, microparticles mixed into the coarse particles rise along with the secondary inlet air again, classification operation is carried out again, and therefore the classification efficiency is improved. The coarse particles obtained after elutriation fall back to a grinding machine along a barrel wall for re-grinding.
Description
Technical field
The present invention relates to ultrafine grinding device, specifically, it relates to a kind of secondary air ultrafine grinding device for pulverizing Chinese medicine.
Background technology
At present, superfine grinding is the new material industry grown up with modern high technology, the milling product of superfine grinding has fine size, good evenness, added value of product advantages of higher, product application is in field of medicaments, research shows, medicine super-refinement after, external application or for oral administration time can improve specific absorption, curative effect and utilization ratio, also can change formulation under suitable condition, use as micron, submicron and nanometer medicinal powder can be made into injection. In medical diagnosis, related ultra fine powder body can be injected or takes after suitably process and in human body, carry out various pathological diagnosis. Although high-purity superfine powder body can be prepared by chemical synthesis, but cost is too high, fail for suitability for industrialized production so far. The main means obtaining superfine powder are still mechanical disintegration modes, and the difficulty mechanically producing superfine grinding that superfine powder relies on and classification technique constantly increases. By the research and development of nearly 30 years, some countries by representative of the U.S., Germany, Japan and USSR (Union of Soviet Socialist Republics) have developed shredder respectively, rotate the superfine grinding equipment of tens of types such as pan mill, liquid stream pulverizer, high-speed impact type pulverizer, freezing crusher. Mechanical process is adopted by crushing material to micron or submicron, but to be difficult to obtain nanometer grade powder typically by mechanical crushing method at present. Having the different pulverizing limit for different equipment, the limit of general comminution by gas stream is in submicron order.
Summary of the invention
It is an object of the present invention to for the problems referred to above, it is proposed to a kind of secondary air ultrafine grinding device for pulverizing Chinese medicine, low with implementation cost, the advantage that efficiency is high.
For achieving the above object, the technical solution used in the present invention is: a kind of secondary air ultrafine grinding device for pulverizing Chinese medicine, comprise support, mill transmission device, housing, rotor, stepped transmission device, turning device, fine powder exports, feeding mouth, mill, main air inlet and pneumatic sealing device, support is the bottom of whole device, base is built with mill transmission device, one end connects rotor, rotor is in the inside of housing, the shape of housing is two trapezoidal docking, the top of housing is connected with stepped transmission device, the stepped transmission device the other end connects auxiliary power set, below stepped transmission device, turning device is equipped with in the inside of housing, turning device bottom connects the fine powder outlet outwards stretched out from enclosure interior, fine powder outlet is streamlined circle pipe, exit is horizontal direction, in fine powder outlet lower section, the lower outside of housing has the feeding mouth upwards tiltedly stretched out, below feeding mouth, what housing bottom was connected with rotor is mill, there is main air inlet the lower section of mill, in addition, also arranging secondary air inlet on the top of fine powder outlet, apparatus body internal surface is pottery surfacing.
The technical scheme of the present invention has following useful effect:
The ultrafine grinding device of various embodiments of the present invention, owing to comprising secondary air inlet, it is possible to improves crush efficiency; Such that it is able to overcome the defect being difficult to obtain nanometer grade powder in prior art, to realize the advantage that ultra-fine precision is pulverized.
Below by drawings and Examples, the technical scheme of the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the super-fine classified mill structure iron described in the embodiment of the present invention;
Wherein Reference numeral is as follows: 1 support, 2 mill transmission devices, 3 secondary air inlets, 4 housings, 5 stepped transmission devices, 6 turning devices, 7 startup tightness systems, 8 fine powder outlets, 9 feeding mouths, 10 mills, 11 main air inlets.
Fig. 2 is powder body motion track sketch;
Powder body motion track after 21-powder mill, 22-meal motion track, 23-fine powder motion track.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, it will be appreciated that preferred embodiment described herein, only for instruction and explanation of the present invention, is not intended to limit the present invention.
As shown in Figure 1, a kind of secondary air ultrafine grinding device for pulverizing Chinese medicine, comprises support, mill driving part, housing parts, rotor, stepped transmission part, rotating part, fine powder exports, feeding mouth, mill, main air inlet, in addition, also arranges secondary air inlet on the top of fine powder outlet.
Wherein support 1 is the bottom of whole device, the material selecting density higher is made, the metals such as such as iron copper, base is built with mill transmission device, connecting power device and rotor, power parts can be motor, diesel engine or petrol motor etc., the inside of rotor housing 4 in the drawings, the top of housing 4 is connected with stepped transmission device 5, the stepped transmission device the other end connects another power set, below stepped transmission device, below stepped transmission device 5, rotating part 6 is equipped with in the inside of housing 4, turning device 6 bottom connects the fine powder outlet 8 outwards stretched out from housing 4 inside, fine powder outlet 8 is streamlined circle pipe, exit is horizontal direction, export below 8 at fine powder, the lower outside of housing 4 has the feeding mouth 9 upwards tiltedly stretched out, below feeding mouth 9, what be connected with rotor bottom housing 4 is mill 10, there is main air inlet 11 lower section of mill 10, it it is support 1 below it, the top exporting 8 at fine powder arranges secondary air inlet 3, and the opening direction that its opening exports 8 with fine powder is contrary.
It should be noted that because disintegrating apparatus certainly exists power set; the type of power set and link etc. are not the major portions that the present invention pays close attention to; arranging according to different situations, power set and mode of connection in the present embodiment do not limit protection domain of the present invention.
Owing to introducing secondary air inlet, in crushing process, when coarse particles falls, introduce the further elutriation of secondary air, make the microparticle being mixed into again increase with secondary air, again carry out graded operation, to improve fractional efficiency. Coarse grain material after elutriation falls back in pulverizer under barrel to be pulverized again.
As shown in Figure 2, after installing secondary air inlet, will there is rising track at discharge port descending phase to the inner powder body motion track of common grinder again in meal track.
Further, preventing drug contamination for adapting to the feature of Chinese medicine own, the body internal surface of this pulverizer is all pottery surfacing. Thickness the best of pottery surfacing is 0.5mm, and due to craft precision relation, effect and the 0.5mm of 0.8mm thickness are close.
