Between dispersion axle 2 and declutch shaft 3, be also provided with cooling solvent delivery device, this cooling solvent delivery device is arranged between two the second hermetically-sealed constructions 5, and this cooling solvent delivery device comprises is located at ring-type conveyor screw outside declutch shaft 3, as shown in Figure 2.Matched in clearance between this conveyor screw 14 and dispersion axle 2.
Drive declutch shaft and declutch shaft to be ground to example respectively with two motors and its course of work is described.
When two motors drive dispersion axle and declutch shaft grinding respectively, the disperser be connected with declutch shaft drives grinding material to rotate both sides inside and outside phase radial dispersion device, from pressure at both sides inside and outside disperser must be made under the effect of power uneven in rotation process, now part grinding material moves from inside to outside along pilot hole, forms the circulation along pilot hole circulation.Because the quality of material ground is little, under separator effect at a high speed, around separator, form the descending inside distribution of radial material diameter, axial material diameter is descending upwards to distribute, what namely quality was large is distributed in outside, and what quality was little is distributed in inner side.
Owing to producing a large amount of heats between the first hermetically-sealed construction and the second hermetically-sealed construction in process of lapping.By suitable configuration, cooling solvent can disperse spindle guide hole 21, second to disperse the channel flow of spindle guide hole 22 and the formation of the second cover guide hole 12 from the first cover guide hole 11, first, and contact with two the second hermetically-sealed constructions with two the first hermetically-sealed constructions respectively, and then the heat produced is taken out of from inside, reduce the operating temperature of hermetically-sealed construction, increase the service life.
In the present embodiment, described twin shaft grinding system comprises heat-exchange device, this heat-exchange device comprises the container 10 containing cooling solvent, be provided with cylindrical coil shape conduit 16 in this container 10, this container 10 is provided with two container joints 15 and container joint 16 be communicated with the second cover guide hole 12 with the first cover guide hole 11 respectively.The temperature of cooling solvent can better reduce by this heat-exchange device, improves cooling effect, makes hermetically-sealed construction have more stable operating temperature.
As required, can be provided with between described first cover guide hole 11 and container joint 15 and cool solvent booster pump (accompanying drawing does not indicate), the flowing velocity of cooling solvent can be increased, and then make hermetically-sealed construction have lower stable temperature.
In the present embodiment, described declutch shaft 3 cavity wall is provided with helical structure, and the ascent direction of this helical structure is identical with declutch shaft rotation direction, because helical structure is when existing rotation, material can be made more easily to export, improving discharging speed.
Described circular spiral body 14 can be one-body molded with declutch shaft 3, also can adopt isolating construction.When adopting circular spiral body 14 and declutch shaft 3 to be isolating construction, there is sheath 13 at described circular spiral body 14 overcoat, this sheath 13 and the contact internal walls disperseing axle 2.Described circular spiral body 14 also can be located at the inwall of dispersion axle 2 as required, circular spiral body 14 and dispersion axle 2 synchronous axial system during work, equally also can realize that cooling solvent is transported to position second from the first dispersion spindle guide hole 21 of lower position and disperse position, spindle guide hole 22, realize the flowing of cooling solvent, and then the cooling to hermetically-sealed construction.
Described declutch shaft 3 is provided with the connecting hole 31 connecting disengagement chamber C, is axially arranged with at separator 3 and disperser 1 the gap B being connected grinding chamber D and disengagement chamber C.Due to the existence of gap B, when described separator and disperser High Rotation Speed, under being formed in grinding chamber D, surface density is large, the state that upper surface density is little, and the pressure in disengagement chamber C is less than grinding chamber D, material ground under the effect of pressure differential like this speed can enter tapping channel output by connecting hole 31, and then also can improve the speed of discharging.
On described disperser 6, annular is evenly distributed with multiple pilot hole 61, under the effect of this pilot hole 61, the interior outside pressure of the disperser 6 during rotation is uneven, and then partial material can be flowed from pilot hole 61, thus material and mill ball can form multiple directions in grinding chamber flows fast, improve grinding efficiency.
Described first cylindrical shell 8 inwall is mountain font cavity, can better coordinate with disperser, improves grinding efficiency.Be provided with the annular protrusion 62 fixing with disperseing axle 2 inside tubular disperser, the top of this projection 62 contacts with the O-ring seal of the first hermetically-sealed construction 4, and its underpart is provided with annular and is evenly distributed with multiple pilot hole 61.Because the first cylindrical shell 8 of this structure coordinates with disperser 6 and separator 7, grinding void space is limited, makes the material of each position and mill ball can have larger speed, and then can improve grinding efficiency, the top of protruding 62 contacts with O-ring seal simultaneously, can improve sealing.
Be provided with the second cylindrical shell 9 outside described first cylindrical shell 8, the cooling cavity formed by gap between this second cylindrical shell 9 and first cylindrical shell 8 or pipeline, this second cylindrical shell 9 be respectively equipped with and the cooling liquid inlet 91 and the cooling liquid outlet 92 that cool cavity or pipeline connection.The temperature of cylindrical shell can be reduced, the service life of extension device.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
