Description

A kind of magnesium chips pulverizer

The utility model relates to a kind of special mechanical equipment of producing pure magnesium powder, magnesium aluminum-alloy powder.

At present; generally adopt ball mill to produce magnesium powder and magnesium aluminum-alloy powder both at home and abroad; promptly at first the raw material milling is become bits to add in the ball mill; feed nitrogen protection simultaneously; become powder under in steel ball, hitting; domestic representative Harbin 101 factories of magnesium powder factory promptly adopt this equipment, and its weak point is: granularity is big, purity difference, material yield rate is low, the amount of labour is big, air pollution is serious.

The purpose of this utility model is to overcome shortcoming of the prior art, provides a kind of and can improve magnesium powder purity, increases the magnesium powder yield, reduces the amount of labour, the magnesium chips pulverizer that granularity is little.

The utility model is achieved in that the magnesium chips pulverizer is made up of charging aperture, reducing mechanism, cooling water runner and discharging opening, reducing mechanism is the housing that is provided with pulverizing chamber, filter chamber, three chambers that communicate of air inducing discharge chamber, charging aperture communicates with pulverizing chamber, and the air inducing discharge chamber communicates with discharging opening.In pulverizing chamber, the filter chamber, on the center of circle line of air inducing discharge chamber a turning cylinder is arranged, pass through driven by motor, in three chambers, on axle, be equipped with respectively on the corresponding position and re-pack, filter and air inducing flabellum, the raw material milling is become bits, add in the magnesium chips pulverizer by charging aperture, magnesium chips is cut into powder by the stranding that re-packs of high speed rotating in pulverizing chamber, in the filter chamber, control magnesium powder degree by the slit of regulating between filter and the body, the air inducing discharge chamber is under the effect of air inducing flabellum, with the magnesium powder by sucking the filter chamber in the pulverizing chamber, raise up away by filter chamber's suction air inducing discharge chamber and by discharging opening again, thereby realize the purpose of this utility model.

The utlity model has following advantage: this magnesium chips is pulverized function and is improved magnesium powder purity, increases the magnesium powder yield, reduces the amount of labour, is the little magnesium chips pulverizer of granularity.Advantages such as the magnesium powder purity of producing reaches 99.4%, and granularity is by 50～140 orders, 100～260 orders till now, and utilization rate of raw materials brings up to 95% by existing 60%, and it is little that the utility model also has investment simultaneously, easy and simple to handle.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a magnesium chips mill structure schematic diagram;

Among the figure: 1-charging aperture, 2-reflecting plate, 3-cooling water runner, 4-reducing mechanism, 5-air inducing flabellum, 6-filter, the 7-bearing block, the 8-axle, the 9-belt pulley, the 10-support, 11-re-packs, the 12-liner plate, 13-air inducing discharge chamber, 14-filter chamber, 15-pulverizing chamber, 16-key or pin, 17-discharging opening.

The magnesium chips pulverizer is by charging aperture 1, reducing mechanism 4, cooling water runner 3 and discharging opening 17 are formed, reducing mechanism 4 is provided with three chambers, they are respectively pulverizing chamber 15, filter chamber 14, air inducing discharge chamber 13, along a turning cylinder 8 is housed on the center of circle line of three chambers, pulverizing chamber 15 re-pack 11, air inducing flabellum 5 in filter 6 in the filter chamber 14 and the air inducing discharge chamber 13 connects with axle 8 by pin or key 16 respectively, axle 8 is driven by belt pulley 9 by motor, charging aperture 1 is the magnetic charging aperture, main effect is a de-iron, on charging aperture 1, be provided with simultaneously reflecting plate 2, prevent that pulverizer from getting the magnesium powder from charging aperture 1 in operation process, around reducing mechanism 4 and discharging opening 17, be provided with cooling water runner 3, produce a large amount of heat when taking away machine run by recirculated cooling water.With raw material (when producing the magnesium powder, raw material is a pure magnesium ingot) mill into bits after, add by magnetic charging aperture 1, iron in the charging aperture 1 adsorbable magnesium chips, avoid producing spark, powder is cut in 11 strandings that re-pack that magnesium chips is rotated at a high speed in pulverizing chamber, be provided with liner plate 12 at the pulverizing inwall, in filter chamber 14, control magnesium powder degree with the slit of housing by regulating filter 6, at a high speed the air inducing flabellum 5 of rotation produces powerful suction, and the magnesium powder is sucked filter chambers 14 by pulverizing chamber 15, is filtered by filter chamber 14 to enter air inducing discharge chamber 13 and raised up away by discharging opening 17 again, the magnesium powder packs after reclaiming immediately, promptly finishes magnesium chips and pulverizes.
