Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As Fig. 1, grinding rotor of the present invention comprise one end be connected with main shaft 1 and by main shaft drive rotate turn core 2, the described core other end that turns is installed with hollow grinding frame 3, in grinding frame, separator is set, turn the rotary body 4 that core and grinding frame form concentric same diameter, turn core ribbon and move grinding frame rotation, be circumferentially provided with dismountable number row grinding block 5 at this rotating body peripheral wall, each is arranged between two adjacent grinding blocks and is provided with dismountable spacing block 6; Be formed with punishment in advance mouth, the inner space of punishment in advance mouth and grinding frame between two row's grinding blocks often adjacent on described grinding frame, material enters grinding frame inner chamber by punishment in advance mouth, then enters separator by inner chamber.Owing to adopting dismountable grinding block and spacing block, when after the wearing and tearing of one of them grinding block, change another new grinding block after only need being dismantled, it changes convenient, and cost is lower.At present, for the grinder of large discharge or super-flow, whole grinding rotor is made monoblock type or ring plate superposing type, not only rigidity is inadequate, affects grinding effect; And difficulty of processing is large, substantially cannot realize; And adopt split-type structure of the present invention, not only can realize the grinding of large discharge or super-flow, and processing is simple, changes substituting stronger.Cannot process due to special material and exceed the rotor that diameter is 1000MM, if adopt erection method of the present invention, larger also can completing.
In the present invention, described core 2 periphery wall that turns forms several horizontal bar (not shown)s vertically, described grinding frame 3 comprises and turns the holder 31 that described in core, other end end face is affixed and the several cross bars 32 be axially connected on this holder, horizontal bar is identical with the cross sectional shape of cross bar, each described horizontal bar forms the boss of rotating body peripheral wall with corresponding described cross bar, and described grinding block and spacing block are set on boss respectively by the draw-in groove 8 opened thereon is alternate; Described boss is being less than the circumferential width away from this perisporium side near the circumferential width of rotating body peripheral wall side, the described draw-in groove on grinding block and spacing block is less than the groove width away from this perisporium side, as dovetail groove etc. in the groove width near rotating body peripheral wall side.So just grinding block can be disassembled from rotor, realize the object changing a certain appointment grinding block.
As Fig. 4, Fig. 5, Fig. 6, the draw-in groove of described each grinding block turned on core 2 radially has opening 21, turn spacing block core being in same radial position and connect into circular ring plate 9, each circular ring plate is circumferentially provided with several described draw-in groove with radial opening, the position of each circular ring plate between adjacent two row's grinding blocks extends extension 91 vertically, is formed with the breach 92 of clamping grinding block between often adjacent extension; Can ensure that grinding block and shading ring are inserted in from boss like this to turn outside core.As Fig. 2, Fig. 3, the axially extending bore that each grinding block on described grinding frame and spacing block are opened is described draw-in groove, and the through hole hole wall of grinding block laterally radial direction extends ground section 51, and the grinding block mainly playing abrasive action can be made like this to connect more firm.
The present invention, by the improvement to rotor shapes and size, adds and realizes conveying and the effect being separated high sticky material.High viscosity conveying rotor, the grinding block of its outside can be arranged to double wedge, and double wedge is equally spaced on rotor outer surface, has arcwall face or concave surface between described adjacent tooth.The present invention is by hydrodynamics, the mechanics of materials, the theoretical research of molecular bond energy and actual tests, confirm double wedge structure, shape and dynamic balancing size, the applicable material viscosity of nanometer sand mill is made to rise to 3000Mpas, solid content can reach more than 70%, and do not have other to ask to grinding technics, substantially covers the powder body material needing fine of more than 85%.
Further, described rotary body two ends are respectively arranged with a gland 10, and described grinding block and spacing block are pressed between two glands, make whole grinding rotor more firm, wherein a gland is axially affixed by screw and described horizontal bar, and another gland is affixed with described cross bar axis by screw.When mounted, first with screw, a gland is fixed on one end of rotary body, again the draw-in groove of grinding block or spacing block is inserted in from the boss of the rotary body other end, then grinding block or spacing block are moved along boss, after all grinding blocks or spacing block are regularly inserted in, another gland is fixed on the described other end of rotary body, thus completes installation.When after some grinding block wearing and tearing, disassemble a gland, then the grinding block be associated with the grinding block of wearing and tearing or spacing block are skidded off along boss, then the grinding block after wearing and tearing is skidded off, then the grinding block more renewed, and stationary gland after being inserted in the grinding block or spacing block be associated.
As can be known from the above technical solutions, the grinding block of large scale lapping device of the present invention and spacing block all adopt the mode of socket to be connected in runing rest main body, when after some grinding block wearing and tearing, the grinding block of these wearing and tearing is changed after only need dismantling rotor gland, its replacement cost is lower, maintenance time is short, specially for large-batch industrial not compartment Production design; The present invention is covered with grinding block at the whole axial direction of rotary body, in order to meet the application of different industries development, avoid again totally reforming the wasting of resources brought, grinding block can be designed to a series of difform module, have the grinding block structure of this series of different profile module, the nano-milled processing step flow process of different industries can be realized, and grinding block is by compressions such as glands, not only sound construction, and grinding effect is better, is also a kind of very economical solution.
Above-mentioned embodiment is used for illustrative purposes only, and be not limitation of the present invention, the those of ordinary skill of relevant technical field, without departing from the spirit and scope of the present invention, can also make various change and modification, therefore all equivalent technical schemes also should belong to category of the present invention.
