Abstract
The present invention relates to a double-barrel circular nanometer sand mill or a stirring mill, which comprises a sand cylinder, wherein the upper part of the sand cylinder is provided with a material discharging pipe, and the lower part is provided with a material feeding pipe. The present invention is characterized in that two circular barrels are additionally arranged, the top parts of the two circular barrels are respectively connected with the material discharging pipe of the sand cylinder, and the bottom parts are respectively connected with the material feeding pipe of the sand cylinder through connecting pipes; the connecting pipes are respectively provided with material discharging valves, and a material feeding pump is arranged on the material feeding pipe. The present invention uses the two circular barrels as intermissive circular tools. Compared with a device with no circular barrel or a device with one circular barrel, the present invention can obtain the same granularity as the devices and has 60% to 80 % shortened milling time, and the granularity is reduced from original maximum 500 nanometers to 200 nanometers even below 100 nanometers.
Description
Technical field
The invention belongs to the superfine powder milling apparatus.
Background technology
The structure of existing sand mill or stirring mill mainly comprises sand cylinder, stirs in the sand cylinder that grinds to have stirring rod, has abrasive disk in the sand cylinder of sand mill, all fills to grind in the sand cylinder to be situated between.Be mainly used in the grinding of liquid-solid mixture material or material oar.Motor drives stirring rod or abrasive disk work by transmission system, and work mainly contains following several situation:
1, do not circulate after the material in sand cylinder is ground, the effect of simple grinding and dispersion is only played in the discharging over there of charging here;
2, do not circulate one pot one pot mill;
3, the monotubular circulation is carried out in monotubular circulation, mill body and circulating tank.
Sand mill or the material that stirs the barreling mill are liquid-solid mixture material or material oar, general percentage meter by weight, and solid material is 10～60%, water accounts for 40～90%.Can be ground to about 1 micron for heavy material, and size distribution is inhomogeneous, for the little material of proportion can only be ground to several micron, size distribution is very inhomogeneous.Because granularity acquires a certain degree, can not sink at the aqueous phase material at once, the material that has is put several days and also can not sunk, so the grinder of these several forms is when abrasive product, because after material reached certain particle size, gravity was inoperative, mill is situated between can't fully grind all materials, cause merit in vain, the granularity of product no longer diminish and size distribution inhomogeneous.
Summary of the invention
It is little that technical problem to be solved by this invention provides a kind of grind size, the double-barrel circular nanometer sand mill of even particle size distribution or stirring mill.
Double-barrel circular nanometer sand mill of the present invention or stirring mill, comprise sand cylinder, sand cylinder top has discharge nozzle, the bottom has feed pipe, it is characterized in that setting up two circulating barrel, the top of two circulating barrel is connected with the discharge nozzle of sand cylinder respectively, and the bottom is connected with the feed pipe of sand cylinder by tube connector respectively, have the discharging valve on the tube connector respectively, feed pump is set on feed pipe.
The present invention does not change the working method of sand cylinder, and sand cylinder still adopts the milling apparatus of prior art, just adopts two to disperse circulating barrel to carry out the intermittent cycle grinding.
Operation principle of the present invention is:
When raw meal particle size is thick, start monotubular circulation (only adopting a circulating barrel), when granularity reaches the 1500 order left and right sides, start bitubular circulation.With two circulating barrel differences is No. 1 circulating barrel and No. 2 circulating barrel, when wherein No. 1 circulating barrel is equipped with material, the discharging valve open of No. 1 circulating barrel, the thing grain enters sand cylinder by the lower end of sand cylinder, grind, through behind the certain hour from the upper end discharging of sand cylinder flow into No. 2 circulating barrel, material in No. 1 circulation circulating barrel is finished by grinding, close the discharging valve of No. 1 circulating barrel, open the discharging valve of No. 2 circulating barrel, and the discharge nozzle of sand cylinder upper end is connected No. 1 circulating barrel, and grinding material flow in No. 1 circulating barrel, when the material in No. 2 circulating barrel is finished by grinding, close the discharging valve of No. 2 circulating barrel, open the discharging valve of No. 1 circulating barrel again, material in the sand cylinder flows into No. 2 circulating barrel, so again and again material is carried out each grinding, effect was very obvious when particularly material reached certain particle size and grinds light material, granularity obviously reduces, and size distribution is very even also very narrow, is reaching breakthrough aspect the grinding superfine powder.
Advantage of the present invention:
The present invention be with two circulating barrel as the intermittent cyclic instrument, the equipment than a no circulating barrel or a circulating barrel reaches same particle sizes, milling time can shorten 60-80%, granularity also drops to 200 nanometers by the original limit 500 nanometers even below 100 nanometers.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, sand cylinder 2, discharge nozzle 3, charging valve 4,6, No. 2 circulating barrel 7 tube connectors 8 of 5, No. 1 circulating barrel of charging valve, discharging valve 9, discharging valve 10 feed pumps 11 feed pipes
The specific embodiment
Fig. 1 is an embodiment of the invention structural representation, below in conjunction with description of drawings.
When wherein No. 1 circulating barrel 5 was equipped with material, the discharging valve 8 of No. 1 circulating barrel was opened, and the thing grain enters sand cylinder 1 by the lower end of sand cylinder, ground, and ground behind the certain hour from the upper end discharging of sand cylinder flow into No. 2 circulating barrel 6; Material in No. 1 circulating barrel is finished by grinding, close the discharging valve 8 of No. 1 circulating barrel, open the discharging valve 9 of No. 2 circulating barrel 6, and the discharge nozzle 2 of sand cylinder upper end is connected No. 1 circulating barrel, and grinding material flow in No. 1 circulating barrel, when the material in No. 2 circulating barrel is finished by grinding, close the discharging valve of No. 2 circulating barrel, open the discharging valve of No. 1 circulating barrel again, material in the sand cylinder flows into No. 2 circulating barrel, so again and again material is carried out each grinding.
The operation of discharging valve 8 and discharging valve 9 and the discharging of sand cylinder top flow into No. 1 circulating barrel and No. 2 circulating barrel respectively both can manually-operated (charging valve or alternate manner are set), also can adopt automatic control or other frame for movement mode.
