Embodiment
The utility model is described in more detail for scheme below in conjunction with the accompanying drawings and preferably.
This specific embodiment is only that it is not to limitation of the present utility model, ability to explanation of the present utility model
Field technique personnel can make the modification of no creative contribution to the present embodiment as needed after this specification is read, but
As long as all protected in right of the present utility model by Patent Law.
Embodiment：As shown in Figure 1, 2, 3, a kind of compact grinder, including frame 1, drive system 2, sand cylinder, grinding
Cylinder includes the cylinder 10 being fixed in frame 1, and axle is connected to the rotor 20 on the output shaft of drive system 2.Thus, in cylinder 10
Annular gap is formed between surface and the outer surface of rotor 20, ink and abrasive media are injected separately into the annular gap, by turning
Son 20 drives abrasive media, and because annular gap is narrow, the rotating speed of rotor 20 is big, and the crush force of sand cylinder, impulsive force are big, crush,
Shear, grind particle in ink and the effect of dough is good.
Further, the outer surface of rotor 20 is covered with the kick 21 being ground for assisted milling medium and ink；
The diamondwise of kick 21, there are a pair of parallel straight edges 211 consistent with the direction of rotor axis 201, a pair and rotor axis 201
Direction formed certain angle angle parallel hypotenuse 212；And any kick 21 with along on the direction of rotor axis 201
Adjacent kick 21 parallel be equidistantly spaced from；Any kick 21 and the adjacent kick 21 along rotor 20 in the radial direction
Dislocation is equidistantly spaced from, further, the parallel hypotenuse 212 of any kick 21 is with being located at the parallel hypotenuse 212 along the kick
The parallel hypotenuse 212 of kick 21 in direction be on same circular helix.Thus, in the extruding of each kick 21
Under, abrasive media is moved by the gradually regular gap arrived between kick 21, and under the high-speed rotation of rotor 20, grinding medium
Matter can be threadingly advanced along the same circular helix being formed between adjacent kick 21, drive ink to be formed close to bolt stream
Flowing, be totally different from scattered dish-type sand cylinder or column type sand cylinder, the wireless speed difference of flowing of ink, can avoid undesirable
Flowing, dead point is few, while avoids local temperature skewness caused by undesirable flowing, ensures the uniformity of ink quality.
In addition, because the annular gap formed between cylinder 10 and rotor 20 is narrow, the loading of abrasive media also significantly subtracts
Few, the material remained in sand cylinder is few, beneficial to switching ink kind, is especially suitable for carrying out Multi-varieties and Small-batch Production, overall
Formula rotor also makes the structure of sand cylinder become very simple, is easily installed, overhauls and cleans.
Further, rotor axis 201 are located at the top of the tubular axis 101 of cylinder 10 so that the top of rotor 20 is with
The gap in portion is inconsistent, specifically, the external surface top of rotor 20 is less than the appearance of rotor 20 with the gap at the top of the inner surface of cylinder 10
The gap of face bottom and the inner surface bottom of cylinder 10.Ink and abrasive media have the trend trickled downwards under gravity,
Ink and abrasive media i.e. at the top of sand cylinder is all fewer than the ink and abrasive media of bottom, the up-narrow and down-wide arrangement in gap, subtracts
Lack the whereabouts trend of the ink at upper gap, maintained the viscosity between ink, reduce vertical undesirable flowing, together
When give more activity spaces of ink at underclearance, prevent excessive ink run on a bank to be formed the uncontrolled type of flow and
The energy expenditure that the type of flow is brought, make ink more smooth in vertical flowing, the distributed number of abrasive media also more rationally, is sent out
Hot degree is low, and grinding effect is more preferable.
Further, grinder also includes being used for the cooling system 30 for cooling down sand cylinder, cooling system 30 includes being located at cylinder 10
Interior outer cooling structure 31 and the interior cooling structure 32 in rotor 20.Outer cooling structure 31 includes outer cooling import 311, outer
The cavity volume of coolant outlet 312, the outer cooling import 311 of connection and outer coolant outlet 312；Interior cooling structure 32 includes interior cooling import
321st, the pipeline of interior coolant outlet 322, the interior cooling import 321 of connection and interior coolant outlet 322.Thus, grinder has cylinder
The double cooling mode of the special cooling structure of 10 special cooling structures and rotor 20, makes ink and abrasive media in cylinder 10
Effectively cooled under the cooling of the two cylindrical surface of surface and the outer surface of rotor 20.
Further, interior cooling import 321 is located at includes pressing close to kick 21 close to the outer side of coolant outlet 312, pipeline
Effect pipeline 323, collect effect pipeline in cooling medium and send out the return line 324 outside rotor 20, thus, outer cooling
It is relatively low to can obtain coolant temperature in interior cooling structure 32 for the higher side of outer coolant outlet 312 of coolant temperature in structure 31
Interior cooling import 321 at effective temperature-reducing, the higher side of effect pipeline 323 of coolant temperature can obtain in interior cooling structure 32
Effective temperature-reducing into outer cooling structure 31 at the relatively low outer cooling import 311 of coolant temperature, reduces whole cooling system
The programming rate and amplitude of cooling medium, make cooling medium more robust in system, reduce the supply of cooling medium unit interval,
Energy consumption is reduced, also just reduces cost.
Further, the annulus barrel of the face rotor 20 of cylinder 10 is hollow structure, and hollow structure forms cavity volume, cavity volume
Interior to be provided with the guiding piece 313 for being used for guiding cooling medium to flow, guiding piece 313 is along cylinder radially by the outer wall of cavity volume and inwall phase
Connection, cavity volume is set to form one along the axially extending helical flow path 314 of cylinder.Thus, same cooling medium is considerably increased with holding
The contact length of chamber, on the premise of keeping cooling medium transporting velocity, the action time of same cooling medium is considerably increased, and
Cooling medium flowing is regular strong, and interfering between cooling medium is few, reduces unnecessary and unfavorable additional energy and heat
Exchange, effective action time greatly increases, good cooling results.
