Fig. 2 is the sectional structure schematic diagram of the utility model preferred embodiment.
Detailed description of the invention
Below in conjunction with Fig. 1, Fig. 2 introduces horizontal sand mill of the present utility model (PHE SuperMaxFlow) in detail, it comprises the sand cylinder 2 be arranged in frame 1, rack-mounted motor 3 and by motor-driven main shaft 4, this main shaft stretches in this sand cylinder from sand cylinder one end, the end face of sand cylinder one end is provided with the feed pipe 21 entered for material, several CbRM(Conicai BeateR Micro be arranged on described main shaft is arranged at intervals with vertically in sand cylinder) abrasive disk 5, the version of abrasive disk can be multiple, as three eccentricity shape, oval or circular etc., and between the abrasive disk of two-phase neighbour, spacer is provided with on main shaft, the effect increasing spacer is: the wearing and tearing of abrasive disk working face are with institute's grind materials distribution situation, abrasive media running orbit, instantaneous sliding speed three is closely related.But the running orbit of abrasive media and instantaneous sliding speed are just determined when the design of sand mill, can not arbitrarily adjustment and change.The gap size distribution situation and the linear velocity that have spacer only can change in order to try.If the arrangement of two adjacent abrasive disk spacing and track density and working face radius thereof set up certain linear relationship, make the adjacent disc spacing apart from working face is far away narrower, the abrasive media be detained increases, shear ability is accelerated, and temperature of charge is higher, more difficult control extra-fine grinding; Otherwise, in track density, larger and instantaneous sliding speed is also larger strengthens adjacent spacing nearby from abrasive disk center, abrasive media in its unit are is suitably reduced, thus reduce abrasive media shear ability herein, slow down the abrasive disk rate of wear, so namely, the situation of that abrasive material skewness of adjustable equidistant abrasive disk, realizes the constant speed abrasive material of working face each point.The calculating of track density is quite complicated, and this section replaces with the distance on tracks'circumcircle, track inscribed circle between adjacent point of contact respectively, i.e. spacer.This was both consistent with objective reality, made again calculating simple and easy.The end cap of the described sand cylinder other end is provided with SCS (Super Centrifugal Separation) large discharge dynamic separator 6, this separator is connected with discharge nozzle 7, when material to be ground enters sand cylinder abrasive areas by the effect of pumping 22 from feed pipe 21, open main motor and drive main axis, the continuous agitation grinding medium of abrasive disk on main shaft, abrasive media is made to clash into material, thus by material refinement, material after refinement under pressure and centrifugal action to the regular movement in separating end region, after material enters separator separation by dynamic classification wheel rotor, the abrasive areas that abrasive media is back under the effect of return port continues to participate in grinding, thus abrasive media can not be deposited in outlet, affect discharging speed and separator blocking, material after refinement then enters its separator, then flow out from discharge nozzle.
As preferably, the end stretching into one end of sand cylinder at main shaft is provided with the DCA(Dynamic Classifier Accelerator of a hollow) dynamic classification wheel rotor 8, arrange described separator in this dynamic classification wheel rotor, this dynamic classification wheel rotor can carry out initial gross separation to material.Specifically, dynamic classification wheel rotor 8 comprises the rotating disk 81 being fixedly installed on described distal end faces and the several connecting rods 82 distributed along rotating disk circumference, one end of each connecting rod is connected with rotating disk, the other end of each connecting rod is connected with a ring plate 83, described separator stretches in the cavity that several connecting rod surrounds from the inner ring of ring plate, cavity is entered by the sorting hole 84 of rotating disk at a part of material of separating end, simultaneously, another part material enters cavity from the gap between several connecting rod, thus initial gross separation is carried out to material, gap between several connecting rod is decided with spindle operation speed speed.
Through hole 51 opened vertically by abrasive disk 5 described in each of the present utility model, a part of material can be made in process of lapping under the effect of feed pressure, to flow to separator from through hole, improved separative efficiency, also can alleviate the weight of abrasive disk, reduced energy consumption.The abrasive disk of this sand mill is or/and rotating disk is provided with accelerator, accelerator has done further research and development on the grinding system " MoliNex " that the whole world is well-known, make whole grinding cavity radial force, major diameter abrasive disk prepares to produce high density energy in efficient volume having, be used for transmitting the energy needing grinding, quote German gradient mechanics design principle and drive abrasive media effective exercise, reduce resistance.Meanwhile, be also provided with extra feeding engine, it is used for convey materials in grinding drum of sand grinder; The abrasive disk of this sand mill and dynamic classification wheel rotor are arranged on same main shaft, can pass on abrasive media by the energy needed for wet lapping and dispersion, reduce the kinetic energy that heat energy is taken away; The energy balance standard material that abrasive media produces on grinding material can be special abrasion-resistant stee, ceramic material or the special material triple IPN net structure high polymer alloy elastomers etc. as PU, PE, specific rubber, these are applicable to water-soluble, oil-soluble, solvent borne, alcoholic product large discharge lapping mode and produce, as batch, continous way, series multistage combined type or circulating.
In implementation process, described motor 3 drives main axis by belt 31, makes stable drive, noise little; Main shaft can be designed to hollow-core construction, and interior logical cooling water reduces operating temperature in grinding chamber, and the speed of mainshaft is adjusted by motor and belt pulley ratio, determines machine rotors end operation line speed with this.Main shaft is arranged on the bearing block 23 of one end described in sand cylinder 2 by bearing, adopts double mechanical seal to seal between main shaft and bearing block end face, improves sealing property, ensures machine stable operation; Be provided with the supporting seat 11 of supports main shaft near described end cap, the end of the main shaft other end is arranged in frame by bearing simultaneously, and this end is provided with another supporting seat 12 supports main shaft, ensures the steady of spindle drive; And described supporting seat and another supporting seat link together, improve stationarity and the noise decrease of transmission further
;described frame is provided with the guide rail 9 for sand cylinder movement
,be convenient to machine dismounting, care and maintenance.
Above-mentioned embodiment is only for illustration of the utility model, and be not to restriction of the present utility model, the those of ordinary skill of relevant technical field, when not departing from the utility model spirit and scope, can also make various change and modification, therefore all equivalent technical schemes also should belong to category of the present utility model.
