Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of preferred embodiment of the utility model;
Fig. 2 is the perspective view of ring plate in the utility model.
Detailed description of the invention
Below in conjunction with Fig. 1, Fig. 2, the utility model is described in further detail:
Sand mill of the present utility model comprises an outer barrel 1 and the horizontal spindle 2 by motor-driven rotation, the interior bucket 3 with grinding chamber 31 is provided with in described outer barrel, discharging chamber 4 is formed between outer barrel inwall and interior bucket outer wall, described main shaft penetrates interior bucket side and is connected with the rotor 5 be arranged in grinding chamber, interior bucket opposite side is provided with the charging aperture 6 being communicated with grinding chamber, this grinding chamber is communicated with discharging chamber by the several points of gaps 7 be arranged on interior bucket, and outer barrel is opened the discharging opening 8 be communicated with discharging chamber.In implementation process, be provided with interlayer 10 in outer barrel 1, in interlayer, be connected with recirculated cooling water, to reduce grinding temperature, take away heat energy, to convert kinetic energy to.When after bucket in material to be ground flows into from charging aperture, point gap that material through grinding passes interior bucket enters discharging chamber, then flows out from discharging through discharging opening, and result design of the present utility model is ingenious, save the grinding space of installing separately separator, be applicable to large discharge grinding process flow.
Specifically, described interior bucket 3 comprises the staving 33 that is made up of several stacked ring plate 32 and is arranged at this staving one end and is positioned at the connecting ring 34 of the described side of bucket, the inner ring of this several ring plate forms described grinding chamber, and the gap between two adjacent ring plates is described point of gap; Described connecting ring side is connected with outer barrel inner wall sealing, leaves described point gap between opposite side and eseparation ring; Be positioned at the described opposite side of bucket be provided with sealing outer barrel and the gland 9 compressing connecting ring and ring plate at the described staving other end, this gland and adjacent ring plate are tightly connected, and gland have been opened described charging aperture, also can open the opening adding abrasive media.After material grinds in grinding chamber, under the effect of feed pressure and centrifugal force, flow into a discharging chamber from point gap.
Further, on another side described in connecting ring 34, described in each ring plate a side on be all circumferentially evenly equipped with at least three grooves 35, the another side of each ring plate circumferentially correspondence is provided with at least three boss 36, each boss snaps in corresponding groove, the groove depth of each groove is less than the length of boss, thus makes to leave gap between adjacent two ring plates; A side described in connecting ring is circumferentially provided with several shank 37, outer barrel inwall correspondence has opened several hole 11, and shank described in each inserts in corresponding hole, can ensure that separator is stablized and gap uniformity like this, abrasive media is avoided to flow out from gap location, contaminated material.When mounted, first by corresponding for connecting rod patchhole, then the boss of the ring plate of slices is snapped in groove, finally compress with gland.This structure need not without the need to using extra connection fastener, and the gap between ring plate is by the length adjustment of boss, can reach the object of collecting and specifying fineness product.In implementation process, no matter boss adopts three, four or five etc., all should keep being distributed in ring plate, the pressure bearing gland so is when mounted comparatively even, and then ensure the uniformity in gap, to improve the uniformity of product granularity, abrasive media is avoided to flow out from gap location, contaminated material.
Alternatively, only boss need be set in ring plate, without the need to opening groove, the length of boss is the width of point gap, so also realizes separation object of the present utility model, when adopting in this way, preferably each ring plate is fixedly connected with, to keep the stability of interior bucket.
In the utility model, be provided with sealing ring 12, sealing ring offer several circumference and divide other through hole 13 described in described outer barrel 1 inwall and connecting ring between side, shank described in each inserts in described hole through corresponding through hole, the sealing property of bucket in improving; Described gland has been opened an annular groove 91, when gland compresses described ring plate, the ring plate adjacent with this gland embeds described annular groove, bottom this annular groove and between ring plate side, be provided with sealing gasket 92, the sealing property of bucket in improving further.
In implementation process, described rotor 5 comprises and is arranged on disk body 51 on described main shaft and along the axially extended sidewall 52 of disk body perisporium, also can installs armature accelerator, and described wall outer surface is circumferentially provided with a grinding block 53, and material is fully ground; Described disk body and sidewall are all opened several material path 54, has improved discharging efficiency; Described outer barrel axial length and its diameter ratio are about 13:9, short/thick type grinding cavity of this ratio and turbine rotor accelerator DSE-Accelerator design element, allow body reach best linear velocity and the input of high-energy-density energy; Meanwhile, the abrasive media scope of application of this sand mill is for reaching 0.05 ~ 1.0mm.
As can be known from the above technical solutions, the utility model adopts bucket separation of material in brand new ideas structure, and turbine rotor accelerator is directly installed in separator, not only saves space, and improves discharging speed.Meanwhile, traditional sand mill and the outer barrel axial length of this sand mill are with the ratio of its diameter dimension because cylindrical shell is elongated, and its volume is comparatively large, so abrasive media loading is more, easily cause material heating in process of lapping, and the abrasive media of lost motion are also many; Tradition sand mill is only just installing discharging separator mesh near barrel discharge hole place, and make the area ratio rate of screen separators area and cylinder inboard wall too small, overcurrent efficiency is low; And this sand mill provides a kind of brand-new discharge method, can realize full-scale discharging, substantially increase discharging efficiency, reduce temperature of charge faster, be kinetic energy by thermal power transfer.
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.
