Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, this ball grinder 100 comprises tank body 10, is located at the cover 20 on this tank body 10 and is located at the valve 30 on this cover 20 top.
This tank body 10 is cylindric, it Damping material layer 13 comprising inner core 11, be sheathed on the urceolus 12 outside this inner core 11 and be located between this inner core 11 and urceolus 12.Described inner core 11 is straight-cylindrical silicon nitride inner core, is formed with the inner chamber 110 of upper end open in it.
Two corners of this inner core 11 in inner chamber 110 bottom form the chamfering 112 of a circular arc respectively, i.e. its inner inner chamber forming a U-shaped.The diameter of the chamfering 112 of this circular arc is the 30%-50% of inner core 11 internal diameter.The setting of this chamfering 112, can eliminate 10 dead angles that cannot grind in tank body and cause the insufficient problem of grinding.The top of described inner core 11 is provided with a cannelure (figure does not mark), is provided with sealing ring 114 in this cannelure.Also be provided with a screen cloth 15 in this inner core 11, the wire side of this screen cloth 15 along the axis of inner core 11 extend and with its dead in line.Described screen cloth 15 is wire netting or polyurethane net, and the inner chamber 110 of inner core 11 is divided into grinding chamber 115 and storage cavity 116 by it.During use, abrasive material polished ball and its chamber wall in grinding chamber of shaping to be broken collide to be pulverized, and qualified abrasive material enters in storage cavity through screen cloth 15, and underproof material then continues in grinding chamber broken, thus improves Grinding Quality.
This urceolus 12 is sheathed on the outside of inner core 11, and its shape is corresponding with inner core 11 shape, and external diameter is greater than the external diameter of inner core 11.A slit is formed between the inwall of described urceolus 12 and the outer wall of inner core 11.The both sides, top of described urceolus 12 form a step 120 respectively.The external diameter of this urceolus 12 above step 120 is less than its external diameter below step 120, and the sidewall of urceolus 12 above step 120 is provided with external screw thread 121.Described Damping material layer 13 is filled in described slit, its effect having abatement vibration and absorb noise, in ball grinder 100 use procedure, can be cut down the vibration of inner canister by the damping action of this damping material 13, absorb the noise of tank body 10 inside.
Described cover 20 is covered on this tank body 10, it Damping material layer 23 comprising inner cap 21, be covered on the enclosing cover 22 on inner cap 21 and be located between this inner cap 21 and enclosing cover 22.The bottom of described cover 20 forms the step 25 corresponding with tank body 10 top, and wall is provided with the internal thread 211 for screwing togather with the external screw thread 121 of tank body 10 in the inner, thus makes cover 20 be covered on formation one complete hermetic structure after on tank body 10.The interior corners place of this cover 20 forms the chamfering 212 of circular arc, the setting of this chamfering 212, can eliminate the dead angle cannot ground in tank body 10 and the problem causing grinding insufficient.
This cover 20 top is provided with valve seat 31, this valve 30 is fixed by screw on valve seat 30, be provided with sealing ring between described valve 30 and valve seat 31, and be provided with a filter 33 in valve 30 and valve seat 31 junction, to prevent powder blocking gas access hole during ball milling.
During use, first unload cover 20, load material to grinding chamber, remove the pollutant on cover 20 and Jar opening sealer face, tighten after building cover 20.Valve 30 is connected with vacuum machine by an intermediate conversion valve, valve-off 30 after vacuum will be exhausted in ball grinder 100 by vacuum machine, again grinding pot is unloaded to be contained on ball mill and carry out ball milling, qualified material after grinding is entered in storage cavity by screen cloth 15 and stores, and underproof material and material to be ground still proceed to pulverize at grinding pot.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
