Description

Rotary cylinder vibrating grinding machine for preparng altra-micro-powder

The utility model relates to powder technology, belong to a kind of equipment for preparing superfine powder, this grinding machine can be widely used in aspects such as fine ceramics, powder metallurgy, mining industry, fine chemistry industry, electronics, building materials, optics, medicine, bioengineering, food, coating and printing and dyeing.

The equipment that is used for material fine grinding and ultra-fine mill at present mainly contains: based on ball mill, vibromill and the jet mill of impact mode and centrifugal mill, tower mill and the ring-roller mill etc. that adopt lapping mode.It is strong and disposal ability is bigger wherein to belong to the adaptability of rotating cylinder grinding machine, it is prevailing a kind of common equipment in the fine grinding operation, but this class grinding machine medium loadings little (φ＜35%), impact grinding stripping effect frequency is low, the grinding active force a little less than, limited further superfine grinding, as the fine grinding and the superfine grinding of material, the energy consumption height, efficient is low.The inventor once was called the utility model application file of " the planet vibrating mill of preparation superfine powder " to Patent Office of the People's Republic of China's submit applications name on December 7th, 1987, obtained patent right, the patent No. is 87216245, it discloses a kind of planet vibrating mill, its purpose is when making this grinding machine work, mill tube had both been done planetary motion, make oscillating movement again, under the acting in conjunction of these two kinds of motions, impulsive force and mill stripping power that the powder grinding medium increasing is applied material, thus make material grinding to ultra-fine grain, and weak point is that planetary mill tube dischargeable capacity is less, the raising of output is restricted, is difficult to satisfy industrialized needs.

The objective of the invention is to avoid above-mentioned weak point of the prior art and a kind of advantage that makes up ball mill, centrifugal mill and vibromill is provided, adopt high-frequency percussion---centrifugal grinding (pushing the double mill stripping of executing) mode, the rotating cylinder vibrating mill of working down in the Centrifugal vibration field of force that makes powder grinding medium be in expansion.This grinding machine output is bigger, widely applicable, but intermittently also continued operation; But but also wet grinding of dry method; Can be vertical also can be horizontal; But single-drum also can many rotating cylinders, and the user can select for use as required, can satisfy scientific research and industrial needs.

The rotating cylinder vibrating mill of preparation superfine powder Combination Design on rotation grinding machine and vibrating mill action principle basis.It is based on the rotating cylinder grinder system, and its operation conditions and vibrating mill are similar.The inventor is designed to cylindrical shape grinding chamber the grinding machine of rotary vibration, cylindrical shell not only rotates but also vibrate, medium is in dither after the match, frictional force weakens and the increase of sliding between medium and barrel or the dielectric layer, therefore the rotating cylinder vibrating mill can be in higher revolutions, so that under overcritical revolution, work, thereby obtain the bigger inertial centrifugal field of force.When grinding machine was worked, mill tube was not only done gyration but also make oscillating movement, and under the superposition of these two kinds of motions, powder grinding medium imposes on high-frequency percussion and abrasive action to material, makes material be able to superfine grinding.

The rotating cylinder vibrating mill of the preparation superfine powder that the utility model provides is made up of drive unit, rotating cylinder mechanism and vibration executing agency three parts.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the structural representation of rotating cylinder vibrating mill, wherein 1, motor; 2, flexible coupling; 3, vibration frame; 4, eccentric activator; 5, gyroaxis; 6, travelling gear; 7, rotating cylinder; 8, support spring; 9, retainer spring; 10, support.

Drive unit is made up of motor 1 and flexible coupling 2.Flexible coupling directly connects motor rotary shaft with gyroaxis 5.

Rotating cylinder mechanism is made up of rotating cylinder 7 and travelling gear 6.Revolving drum requires to be designed to monotubular or many according to demanding party.The driving gear drive driven gear that is installed on the gyroaxis 5 makes the cylindrical shell revolution through double reduction.

Vibration executing agency is made up of gyroaxis 5, eccentric activator 4, vibration frame 3, support spring 8 and retainer spring 9.Gyroaxis 5.Travelling gear 6 and rotating cylinder 7 are installed on the vibration frame 3, and vibration frame 3 places on the support spring 8, constitute a vibratile framework.The eccentric activator 4 that is installed in gyroaxis 5 two ends is directly driven by motor with gyroaxis 5, does rotation at a high speed, produces centrifugal inertial force and makes whole frame vibration.The vibration frequency f=1500 of grinding machine～2000 time/minute; Amplitude λ=5～10 millimeter; Medium filling rate φ=20～50%; Rotating cylinder rotation speed n 〉=42.4/ (D) rev/min, wherein D is the rotating cylinder diameter, optimum valuing range is 0.5 meter of 0.1 meter～φ of φ.In addition, because grinding machine starting and when shutting down moment resonance can cause and come off the strong swing of framework that ad hoc have two registration springs 9 in order to prevent support spring.

According to inventor's design philosophy, rotating cylinder mechanism to be done suitably to change, the rotating cylinder vibrating mill can be expanded and derive many vibrating mills.The rotating cylinder vibrating mill can be made batch (-type) or continous way.The rotating cylinder mechanism of batch (-type) rotating cylinder vibrating mill can be fixed on the vibration frame revolution or live splint and be contained on the vibration frame and turn round; The rotating cylinder mechanism of continous way rotating cylinder vibrating mill is installed on the vibration frame, adopts the hollow shaft system of common rotating cylinder grinding machine, realizes the continuous flow rate and the discharging of rotating cylinder.The number of the rotating cylinder of continous way rotating cylinder vibrating mill is 1～13, and rotating cylinder can independently be provided with or be provided with in succession or be the mutual superimposed setting of falcate, the rotating cylinder number with single, 4 and 6 be the best.The cylindrical shell of many vibrating mills is provided with preferred plan as shown in Figure 2, wherein A is single rotating cylinder, B is that 4 rotating cylinders are provided with schematic diagram in succession, C is that 4 rotating cylinders are the falcate superimposed schematic diagram that is provided with mutually, D is that 6 rotating cylinders are provided with schematic diagram in succession, and E is that 6 rotating cylinders are the falcate superimposed schematic diagram that is provided with mutually.
