The specific embodiment
Referring to Fig. 1 to Fig. 3; A kind of optimal way of nanoscale high-flow pin-type sand mill of the present invention is shown; Comprise frame 1 and be arranged on the sand cylinder 2 that seals by left and right end cap 21,22 on the frame; Rotating shaft 5 is passed said left end cap 21 and is stretched in the sand cylinder, is installed with a rotor 6 in the rotating shaft 5, and the rotor perisporium is equipped with number row rod pin 61 vertically.Material gets in the sand cylinder 2 from the feed pipe 3 of sand cylinder left end; Material in sand cylinder and abrasive media are under the effect of epitrochanterian rod pin 61 rotations; Constantly bump and produce centrifugal force; Make the abundant dispersion grinding of material, utilize dynamic centrifugation principle that the material after the grinding is flowed out from discharge nozzle 4 through separator 7 then.One end of said rotor 6 is installed in the rotating shaft 5, and the other end of said rotor is provided with groove 62 vertically, and an end of said separator 7 is fixed on the right end cap 22, and the other end of said separator passes right end cap and extend in the said groove 62.So just, can shorten the length of sand cylinder effectively and increase diameter, thus rotating shaft can design very short very thick, thereby improve the rotary speed of rotating shaft, increase material and the linear velocity of abrasive media in sand cylinder, to the abundant dispersion grinding of material, the assurance grinding precision; And the diameter of increase sand cylinder, can make the percent of pass of material higher, charging and discharging speed is faster, improves grinding efficiency.Separator described in the present invention is dynamically big flow cyclone, and its gap minimum can reach 30 microns, and the abrasive media filling rate in the sand cylinder can reach more than 96.5%, and rotor also can increase with the diameter of rod pin, and this all helps to improve grinding effect.
In the course of the work, like the sand mill of a 20L, its root diameter is 312mm, and the rotary speed of rotating shaft is 757rpm, is about 12.5m/s through calculating the linear velocity that can obtain rotor.Rotary speed as with rotating shaft increases to 1600rpm, and then the linear velocity of rotor can reach more than the 25m/s, the energy that this is produced in the time of can improving the sand mill dispersion grinding greatly, thus reach dispersion grinding effect rapidly and efficiently.
In the present embodiment, a said end of said rotor 6 is formed with inserting groove 63, and said rotating shaft 5 one is end formed to have the Plug Division 51 that cooperates with inserting groove, and said Plug Division 51 is passed left end cap 21 and inserted in the inserting grooves 63.Said inserting groove is an annular groove, and said Plug Division is an annular protrusion.In implementation process, interference fit that can be through annular protrusion and annular groove is installed in an end of rotor in the rotating shaft, also can connect the end that rotor one end is installed in rotating shaft with screw vertically, and other connected mode can also be arranged.
Be provided with the cooling duct 8 that is interconnected between said rotating shaft 5 and the rotor 6; Be provided with the cooling duct 8 that is interconnected between said sand cylinder 2 and the right end cap 22.Can design two cooling recirculation systems through above-mentioned cooling duct; One of them cooling recirculation system is: cooling water or other cooling fluid get into the cooling duct of rotor from the cooling duct 8 of rotating shaft; Flow out from rotor then, like this can be simultaneously to rotor and rotating shaft cooling.Its implementation has multiple, such as: bearing can be set on rotor, the cooling duct that is interconnected with rotor is set in the bearing, thereby water or other cooling fluid after the circulation are flowed out from bearing; Another cooling recirculation system is: cooling water or other cooling fluid get into the cooling duct 8 in the sand cylinder through coolant pump from the sand cylinder downside; Flow out from the sand cylinder upside cooling duct through right end cap again; Can guarantee like this to be full of cooling water in the cooling duct of whole sand cylinder; Simultaneously, can increase chilled water unit at the right end cap place, and below the right end cap discharging opening, set up relief valve 23 and discharge gate for better temperature control when satisfying discharging; The inconvenience that is brought when avoiding equipment to shut down in the running or suddenly, also available certainly have other mode to realize this cooling recirculation system.The realization of these two cooling recirculation systems not only can be lowered the temperature to sand cylinder; Also can cool off rotating shaft and rotor, make the mechanical temperature of entire machine reduce the heat energy that is produced in the time of also can controlling the rotary speed that improves rotating shaft; Further improve grinding efficiency, guarantee product with stable quality.
In implementation process; Can sand cylinder be designed to very short very thick; Rotor is designed to hollow shape and opens the strip through-hole 64 that groove communicates last, makes the time of staying of material in sand cylinder short, and the material circular flow is big; Perfect heat-dissipating can be used the dynamically big flow cyclone that length is long, diameter is thick, the gap is little, precision is high simultaneously.The length of ordinary circumstance separator is about 1/2 of sand cylinder length; Diameter is about 1/3 of sand cylinder internal diameter; Can guarantee better grinding effect like this, also can select thinner abrasive media, improve the filling rate of abrasive media in sand cylinder; Can make the precision of abrasive product reach nanoscale in this way, and product the particle diameter detecting instrument following show that the particle diameter distributions is narrow.In implementation process; It is better to be used the automatic control system effect, as the product energy consumption value parameter can be imported setting in advance, when guaranteeing that the sand mill energy consumption reaches setting value; The expression product has reached estimates to grind the fineness that requires; This moment, the sand mill autostop both guaranteed the stability of product quality, had practiced thrift energy consumption again.
In the present invention, open the strip through-hole 64 that communicates with said groove between adjacent two row's rod pins 61 of said rotor 6.Not only alleviated the weight of whole rotor, cut down the consumption of energy, and can let material and abrasive media accumulate in around the separator fast; Under action of centrifugal force, abrasive media is by dynamic separator separates, and material is got rid of into and flows out from discharge nozzle in the separator simultaneously; So just, separation and circulation rate have been improved; Thereby make that charging and discharging speed is quicker, further improve grinding efficiency, guarantee product quality.
The foregoing description only supplies to explain the present invention's usefulness; And be not to be limitation of the present invention; The those of ordinary skill in relevant technologies field under the situation that does not break away from the spirit and scope of the present invention, can also be made various variations and modification; Therefore all technical schemes that are equal to also should belong to category of the present invention, and scope of patent protection of the present invention should be limited each claim.
