Description
Technical field
The present invention relates to a kind of vibromill micron ultra shifter, particularly a kind of have a nanometer Al
2O
3With ZrO
2Mix and obtain the micron ultra shifter of high tenacity ceramic material as vibromill cylindrical shell lining and abrasive body.
Background technology
The Chinese medicine ultramicron is pulverized and internationalization of tcm is heat subject of Modern Manufacturing Technology.Be applied to the mechanized equipment in this field, as ultra-fine grinding, micro mist is broken, devices such as ultramicro grinding arise at the historic moment, by strong extruding, shear, impact, bump, collision, grind, friction, cut stranding, the hole blast, mechanical crushing such as turbulence, though can reach the purpose that makes the material ultramicro grinding, but also cause material accepting the fierce impact of metal material percussion grinding component simultaneously, bump, collision, grind, cut stranding, heating reduces mechanical performance and influence and reduction by the biologically active of ultramicro grinding material in the ultramicro grinding processes such as friction, appearance heavy metal break flour particulate in various degree peels off and disengages simultaneously, as chromium, nickel, cadmium, titanium, iron, copper, zinc, plumbous, heavy metals such as arsenic, make ultramicro grinding process Chinese traditional medicine raw material be subjected to severe contamination, lose original medical value.With the Reishi sporule is example, usually micron ultra shifter is pulverized Reishi sporule, though sporoderm-broken rate is not quite similar, but because the breaking trachytectum of glossy ganoderma difficulty is big, cause in the broken wall process micron ultra shifter metal material percussion grinding component with in the bump of fierceness and wearing and tearing, disengaged plurality of heavy metal break flour particulate by comminuting matter inevitably.Discover, Reishi sporule is the extremely fine avette spore of brown (5-7 * 10-12 μ m), the prestressing force that has wonderful workmanship excelling nature on the spore structure is learned structure, particularly the sporoderm main component is chitin, silicon, calcium composition, also contain cellulose, resin, polysaccharide, protein etc., give diameter and had only several microns extremely strong toughness and the fastness of Reishi sporule, caused Reishi sporule pollution-free high-efficient rate broken wall to become the ultramicro grinding a great problem.
Summary of the invention
The purpose of this invention is to provide a kind of micron ultra shifter, utilize this device ultramicro grinding material can reach 0.1～2 μ m, and keep high bioactivity with nano material making high tenacity ceramic component.
The structure of apparatus of the present invention is similar to common industrial micron ultra shifter vibromill, it is characterized in that having with nanometer Al
2O
3With ZrO
2Carry out mixed vibromill cylindrical shell lining and the abrasive body that the high tenacity ceramic material makes that get, before ultramicro grinding or the ultramicro grinding process spray into the cooled with liquid nitrogen agent, realize that the heating of continuous flow procedure percussion grinding component can obtain cooling in time, makes micron ultra shifter be suitable as the continuous process units of industrialization of the ultramicro grinding broken wall of Chinese medicine or Reishi sporule.
Described nanometer Al

3With ZrO
2Carrying out mixed high tenacity ceramic material cylindrical shell lining and abrasive body and be with purity is that 90～99.6% (being generally 91～99.4%), granularity are the monocline pure zirconia (ZrO mutually of 0.5～1.6 μ m (being generally 0.7～1 μ m)
2) or chemical co-precipitation method technology zirconia (ZrO
2) raw material, mixing purity is the flexibilizer nano aluminium oxide (Al of 90～99.6% (being generally 91～99.4%)
2O
3), also can add yittrium oxide (Y
2O
3), in the magnesia (MgO), calcium oxide (CaO) one or more, addition is that 0.2～20%wt (is generally 0.5～5%wt); According to the required specification prefabricated molds base of device, form at 1200～1620 ℃ of (being generally 1400～1600 ℃) temperature sintering.
Described high tenacity ceramic material can be the high tenacity zirconia ceramics, zirconia toughening silicon nitride ceramics, toughening composition zirconia ceramics.
The specification of the high tenacity ceramic cylinder lining of described vibromill: the different model specification according to cylindrical shell determines that high tenacity ceramic cylinder lining gauge thickness generally is 20～100mm, is generally 35～70mm.
The high tenacity ceramic grinding body of described vibromill can be ball milling body, short column body or cylinder; Ball milling body format diameter is that 10～70mm (is generally 18～42mm); Short column body format diameter is that (be generally 18～32mm), length is that 20～120mm (is generally 25～70mm) to 10～40mm; The cylinder format diameter is that (be generally 18～32mm), length is that 120～850mm (is generally 150～500mm) to 10～45mm.
The placement amount of the high tenacity ceramic grinding body of described vibromill is decided on its cylindrical shell model specification and abrasive body size specification, is generally 180～800, is generally 250～500.
The common industrial vibration mill that the present invention relates to can be the inertial oscillation mill and revolve vibromill partially.
When device of the present invention uses, can be according to pulverizing of the requirement of thermal sensitivity biomaterial to temperature, before pulverizing or crushing process in cylindrical shell, spray into liquid nitrogen as cooling agent, straying quatity is 0.05～1 times by the pulverize and break cellular wall weight of material, is generally 0.1～0.3 times.
Device of the present invention is by control zirconia (ZrO
2) material purity, granularity and sintering temperature, mix flexibilizer nano aluminium oxide (Al
2O
3), also can add yittrium oxide (Y
2O
3), magnesia (MgO), in the calcium oxide (CaO) one or more, obtain the high tenacity ceramic material grinding component of anti-percussion of high rigidity, fine and close tough and tensile, wear-resistant, erosion resistance, anti-thermal shock, and be applied to the cylindrical shell and the abrasive body of common industrial micron ultra shifter vibromill, as be embedded in vibromill cylindrical shell lining and as abrasive body, the biomaterial ultramicro grinding effect of strict crushing process not being had metallic pollution is very good.Fierce high impact forces percussion of vibromill and abrasive action cause very easily frictional heating of abrasive body, the cooling-cycle device that is equipped with is not obvious to the high tenacity ceramic grinding body cooling effect of heating, therefore, the present invention proposes for pulverizing the thermal sensitivity biomaterial, can be before pulverizing or crushing process in cylindrical shell, spray into liquid nitrogen as cooling agent, abrasive body can obtain effective cooling at the utmost point in the short time, makes by the Chinese medicine of pulverize and break cellular wall or Reishi sporule to reach the effect of ultramicro grinding broken wall in the short time at the utmost point.The high tenacity pottery of the present invention's preparation is as the micron ultra shifter of vibromill cylindrical shell lining and abrasive body, the ultramicro grinding material can reach 0.1～2 μ m, and the maintenance high bioactivity, according to detection, sporoderm-broken rate reaches 99.9% Reishi sporule or Chinese medicine ultra micro powder after crushed.Because contact vibromill cylindrical shell of material and abrasive body are the high tenacity ceramic material of high rigidity, wear-resistant, erosion resistance, anti-thermal shock, by pollution-free in the Chinese medicine of ultramicro grinding broken wall or the Ganoderma spore micropowder, heavy metal break flour particulates such as Chrome-free, nickel, cadmium, titanium, iron, copper, zinc, lead, arsenic peel off and disengage, heavy metal free pollutes, can Chinese medicine or the Reishi sporule medical value after ultramicro grinding be more widely used through further being processed into medicine, health food.
