Description
One, technical field:
The utility model relates to a kind of ultrafine powder grinding device, belongs to a kind of ball mill grinding machinery device.
Two, background technology
Along with high-tech sectors such as coating, functional form ceramic material, multi-element metal and non-metal alloyization, fuel, printing ink, magnetic material, cosmetics, powder metallurgy, bioengineering are broken at many micro mists to the becoming more meticulous of product requirement, ball mill grinding technology, the ultramicro grinding field is applied.For many years around the power consumption height of ball mill, the steel consumption is high, capacity usage ratio is low etc., and problem has been done number of research projects.But never fundamentally solve, its structure is still prolonged with ancient for many years ball mill grinding machinery, and material in promptly drive is packed into by a rotary cylinder body and abrasive media impact mutually with abrasive action material is pulverized, and its structure was not done material alterations so far.For this ball mill grinding machinery, but D
50During＜10 μ m, along with D
50Minimizing, the power consumption that compares sharply increases, it is a lot of that this shows when ball mill is used for ultra-fine grinding that its crush efficiency reduces.For addressing this problem, increase various difform stiffeners in inner barrel, perhaps change ball milling barrel diameter and length ratio, change the interior material ratio of cylindrical shell etc., but effect not clearly.Seek out thinner product and have only the ball milling time of prolongation, so not only increase cost, also reduced the quality of product, the particularly mechanical alloying of multi-element metal or ceramic material, require powder to be ground together by even dispersion ground, the prolongation ball milling time reaches metallurgical binding between phase and phase, even can not obtain meeting the requirements of the effect of the uniform alloying of composition.In 200420079766.5 patents, a kind of Two-Way Rotary Ultra-Fine Grinding Milling Device is disclosed, it is to install one to make the axle of rightabout rotation with cylindrical shell in cylindrical shell, and the whirligig that spool is provided with the pin clavate of this rotation also is provided with rectangular wear-resistant block in the cylindrical shell.Because what this device used is the whirligig of pin clavate, cylindrical shell is done direction rotation mutually with the axle of rotation during ore grinding, makes energy consumption raise and grinding efficiency increase not in direct ratio.Particularly, require powder to be ground together, reach the material of metallurgical binding between phase and phase, be difficult to reach the product quality requirement by even dispersion ground for the mechanical alloying of multi-element metal or ceramic material.
Three, summary of the invention
The purpose of this utility model is to provide a kind of ultrafine powder grinding device, by the rotating shaft of a band agitating device is set in cylindrical shell, improve the movement velocity and the collision dynamics of ball, the grinding charge material is ground together by even dispersion ground, reach the requirement of metallurgical binding between phase and phase, shorten ball mill and pulverize the time, improve grinding efficiency, cut down the consumption of energy, reduce grinding machine and grind cost.
Fig. 1 is the utility model composition structure chart of the present utility model, and it comprises cylindrical shell 1, rotating shaft 2, transmission device 3, stirring vane 4, support member 5, swivel bearing 6, seal 7, rearmounted cover plate 8.Rotating shaft 2 is arranged in the cylindrical shell 1, rotating shaft is a quill shaft, there is through hole at the axle center, stirring vane 4 is arranged on the rotating shaft 2, rotating vane is the obvolvent activity, the distance of blade and barrel wall is adjustable, rearmounted cover plate 8 is connected with cylindrical shell, the barrel support part 5 that is connected with rearmounted cover plate is provided with on the rotating shaft 2 symmetrically, rotating shaft passes rearmounted cover plate 8 and is supported on the support member 5, end outside barrel support part 5 and rotating shaft 2 place cylindrical shells is provided with swivel bearing 6 and rotation shaft drive 3, and seal 7 is arranged on rotating shaft 2 and cylindrical shell 1 interface.
When starting transmission device, the driven rotary axle rotates, and cylindrical shell maintains static, and drives the agitating device high speed rotating by rotating shaft, and material and abrasive media move in the drive grinding machine.
The utility model advantage and good effect compared with prior art
1, by the rotating shaft of a band agitating device is set in cylindrical shell, improve the movement velocity and the collision dynamics of ball, the grinding charge material is ground together by even dispersion ground, reaches the requirement of metallurgical binding between phase and phase, and the ball milling probability reduces, and has guaranteed the formation of crushing efficiency and mechanical alloying.
2, this equipment is that cylindrical shell maintains static, and drives the agitating device high speed rotating and homogenising is stirred by rotating shaft, thereby drives the motion of material and abrasive media in the grinding machine, has both guaranteed to grind and the efficient of mechanical alloying, saves the energy again.
3, the time of pulverizing the general horizontal ball mill pulverizing of time ratio shortens 10-20 doubly, and production cost is low, the production efficiency height.
Four, description of drawings:
Fig. 1 is a composition structure master cutaway view of the present utility model.1 is cylindrical shell among the figure, and 2 is rotating shaft, and 3 is transmission device, and 4 is stirring vane, and 5 is support member, and 6 is swivel bearing, and 7 is seal, and 8 is rearmounted cover plate.
