Description

Ultrafine crusher

The utility model relates to a kind of powder processing equipment that can carry out ultra-fine grinding to the material of various hardness.

Because the needs of modern industry, superfine powder more and more is applied among the basic material of industries such as chemical products, beverage, food additives, cosmetics, microelectronic material, pottery, building materials.Yet the cost of the airslide disintegrating mill of domestic a large amount of uses is too high, equipment is complicated, energy-consuming consumptive material is serious, floor space is big, be difficult for installation and maintenance, makes some enterprises not dare to inquire.At these situations, some ultrafine crushers are developed in various places, though each has something to recommend him, also there are a lot of unsatisfactory parts.Disclose a kind of " circular motion vibrating mill " as Chinese patent 89100422.X, it has four air springs, is connected with the rigidity Hooke's joint between motor and the grinding machine, and two pulverization cylinders are horizontal parallel and arrange.Air spring structure in this grinding machine is complicated, will inflate in advance before using, and also will support with its thing after the use.Hooke's joint is prone to rigidity and damages in operation process, and cost is higher.This grinding machine can only once grind owing to adopt the operating type of bitubular parallel connection, and it is also big to be equipped with power.

The purpose of this utility model is exactly for overcoming the deficiency described in the background technology, and provide that a kind of volume is little, cost is low, output is high, regrind and the big ultrafine crusher of levigate ratio.

Above-mentioned purpose solves by following technical solution:

This ultrafine crusher comprises base and the pulverization cylinder of abrasive media is housed that the vibrator polyphone is fixed in the rotating shaft.It mainly is with three triangular in shape being separately fixed on the support of pulverization cylinder, the pulverization cylinder that has charging aperture communicates with the pulverization cylinder that has discharging opening by isocon respectively, be connected by soft connection device between motor shaft and the rotating shaft, also connect between two rotating shafts by soft connection device.Said soft connection device is to be linked to each other with ring flange by the flexible material that takes the shape of the letter U to form.Axle of spring between base plate and the base and the angle between the horizontal line are 85 °～90 °.Angle between three pulverization cylinders respectively is 50 °～70 °, and support and base plate are connected as a single entity.

The B-B profile of Fig. 2: Fig. 1.

Fig. 3: the structure for amplifying schematic diagram of soft connection device.

The A-A profile of Fig. 4: Fig. 3.

Now in conjunction with the accompanying drawings the utility model is done an explanation.

As shown in Figure 1 and Figure 2, between base plate 14 and base 10, be fixed with two row's cylindrically coiled springs 9 along the length direction of pulverization cylinder 4, on the section of vertical pulverization cylinder 4 axial lines, the axis of each spring 9 and angle β=85 between the horizontal line °～90 °.Support 5 is fixed on the base plate 14, in be equipped with abrasive media as the rod, ball three pulverization cylinders, 4 triangular in shape being fixed on the support 5.Wherein, the pulverization cylinder 4 that has a charging aperture 6 is positioned at the upper end, and is communicated with the pulverization cylinder 4 that is positioned at the bottom and has two arranged parallel of discharging opening 8 respectively by isocon 11, and the angle of α shown in the figure is 55 °～65 °.Rotating shaft 12 and support 5 concentric fits, the eccentric block that is provided with vibrator 3 in rotating shaft 12 side by side is same direction, also can adjust its relative angle on demand.Be connected by soft connection device 2 between rotating shaft 12 and the motor shaft 13, between two sections rotating shafts 12, also be equipped with soft connection device 7.

Shown in Fig. 3,4, said soft connection device the 2, the 7th is made of ring flange 17, flexible material 16 and screw 15.Wherein, two ring flanges 17 are fixed on rotating shaft 12 and the motor shaft 13 by bolt 18 respectively and between two rotating shafts 12, and the flexible material of being made by rubber, nylon etc. 16 is the U font and is connected with ring flange 17 by screw 15.

This machine in the running, rotate by the flexible material 16 driving rotating shafts 12 of soft connection device 2 by motor 1 and motor shaft 13, drive vibrator 3 again and produce the vibration effect, thereby make the support 5, pulverization cylinder 4, isocon 11, rotating shaft 12 and the base plate 14 relative springs 9 that are fixed together make whole dither.The soft connection device of installing between two sections rotating shafts 12 7 identical with soft connection device 2 structures its objective is in order to coordinate the vibration relation between motor shaft 13 and the two sections rotating shafts 12, and more a step strengthened vibrating effect and raising pulverizing speed.

The object of need pulverizing continuously or be interrupted and enter pulverization cylinder 4 from charging aperture 6 carries out secondary in two pulverization cylinders 4 below isocon 11 branches to again and pulverizes after pulverizing for the first time, again through discharging opening 8 continuously or be interrupted and discharge, finish whole crushing process after the pulverizing.Can also charging and discharging mouth and abrasive media be adjusted accordingly according to the requirement of output and fineness.

The utility model is owing to adopt soft connection device to cooperate the dither of generation and the unique texture that secondary is pulverized with vibrator, average fineness after material is pulverized is 5 microns, and between the 5-50 micron, can adjust its required fineness, to also reaching above-mentioned fineness after the pulverizing such as higher material of Mohs' hardness such as quartz.This machine does not need supporting classifying equipoment, so simplified technological process and reduced equipment cost, compares power consumption with airslide disintegrating mill, ball mill etc. and can reduce by 30～4%.This machine compact conformation can whole Transporting and installation, and floor space is little, in light weight, no dust pollution and noise are lower.Can be widely used in industries such as refractory material, construction material, electronic material, industrial chemicals, metallurgy, pottery, papermaking, medicine, glass, food, magnetic material, pigment, cosmetic material, coating and abrasive material are carried out ultra-fine grinding to material needs.
