Detailed description of the invention
Below in conjunction with Fig. 1, Fig. 2, Fig. 3, the utility model is described in further detail:
Sand mill of the present utility model comprises frame 1, rack-mounted staving 2 and is driven the vertical principal axis 4 of rotation by motor 3, and motor is arranged in frame, and motor is rotated by drive shaft such as belt, chain, reductors, charging aperture 21 is provided with on the upside of staving, and have pressure sensor, described main shaft drives the grinding rotor 5 be arranged in staving grinding chamber 22 to rotate, described rotor is by a lower surface upwards shaping inner chamber 51, this interior cavity inner sleeve establishes a stator 6, material passing passage 7 is provided with between this stator and rotor, dynamic centrifugal separator 8 is provided with on the upside of described stator, described material passing passage is by the material guiding separator after grinding in staving, the discharge nozzle 9 be communicated with separator is provided with in stator, and have temperature sensor, described staving upper end is closed by mechanical seal, lower end is sealed by end cap 10, described stator lower end is fixed on end cap, described discharge nozzle stretches out end cap.In implementation process, after material flows to from charging aperture, on rotor top along with rotor balancing rotation uniformly dispersing, moving downward along staving, now in the cylindric gap that rotor centrifugal field and inner wall of barrel are formed, product obtains pretreatment thoroughly; Again by material passing passage guiding grinding rotor inwall, again grind material between stator and grinding rotor inwall, now material is moved from bottom to top by pressure, finally flows out from the separator of upside; Visible, the structure of this sand mill makes material ceaselessly grind in process from top to bottom, from bottom to top, substantially increases the quality of product.
In the utility model, be provided with a stepped hole 53 bottom described inner chamber 51, described dynamic centrifugal separator stretches in this stepped hole, leaves gap between stepped hole inwall and separator outer wall.The structure of sand mill can be made so compacter.Gap between the step surface of the gap between described armature accelerator lower surface and described end cap upper surface, the gap between rotor internal cavity inwall and stator outer wall, described stepped hole and stator upper surface forms described material passing passage, this material passing passage is communicated with grinding chamber and described gap, thus by material passing passage by the material guiding separator after grinding in staving.
In the utility model abrasive media be separated near separator, i.e. the top of armature accelerator, abrasive media accelerates to maximum peripheral speed by interior deflector of establishing.As preferably, several open slot 54 has radially been opened on described rotor 5 top, each open slot and described gap area, because abrasive media is different from the density of material, abrasive media is by centrifugal force separate and turn back in the cylindric gap that initial rotor centrifugal field and inner wall of barrel formed by epitrochanterian described open slot; Along with the inflow of new material, separated abrasive media participates in again grinding, and so, in the grinding chamber closed, abrasive media forms circulation.
Described stator 6 is in hollow form, top in this stator cavity 61 is installed with a cylinder 62, this cylinder outer wall and cavity inner wall are tightly connected, described separator is installed in cylinder upper end, cylinder is opened conical cavity 63 vertically that be communicated with separator discharging chamber, bottom this conical cavity, is communicated with described discharge nozzle.After the material after grinding flows out from the discharging chamber of separator, material to be led discharge nozzle by the guide functions of conical cavity, to improve discharging efficiency, better distinguish grinding material and non-grinding material region simultaneously.
In the utility model, described inner wall of barrel, rotor outer wall and stator outer wall are provided with the design of excellent pin 11, three layers pin rod not only allows material grind fully, milling area is increased, and the diameter of abrasive media can be used less; Because the many and abrasive media of rod pin quantity does relative motion between three layers of rod pin, material is under equal conditions subject to, and frequency that abrasive media clashes into is eager to excel more than 10 times, improves product quality further, guarantees that the fineness of grinding material reaches Nano Particle distribution; And improve grinding efficiency; Reduce energy consumption.The described rod pin of described inner wall of barrel and stator outer wall is all in spiral distribution, and make the grinding of material more abundant, running orbit meets equation principle more; Interlayer 23 is equipped with in described staving and sleeve rotor, recirculated cooling water is connected with in interlayer, be convenient to the heat produced when taking away the macro-energy grinding of high specific energy consumption, quick cooling temperature of charge makes material under ultralow temperature, carry out the grinding of more low energy consumption, to guarantee that material can not destroy its original chemical characteristic because temperature is too high; As preferably, described separator is threaded with stator, and being threaded connection can be for convenience detach.
As preferably, described main shaft 4 lower end edge has axially opened inserting groove 41, and described armature accelerator 5 upper end is provided with shank 52, and main shaft inserts inserting groove rotor driven by shank and rotates, and as when grafting, key can be adopted to be connected with the mode of groove.This structure, for brand new design vertical grinding machine, not only can be avoided main shaft long, affect transmission effect; And, the height of sand mill can be done more, specifications and models do more comprehensively, meet large batch of industrial production demand, be applicable to the grinding of large discharge; Moreover the shank of this rotor stretches out the inserting mode of staving, be conducive to adopting mechanical seal to seal to staving, thus raising sealing effectiveness, ensure that the permanent stable operation of machine is wanted, can realize disperseing continuously material online and grinding to have possessed more efficient advantage easily.
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.
