Abstract
The utility model discloses an iron or steel cake crushing device, which is composed of a motor 1 and a crusher 2, wherein, the rotating speed of the crusher 2 is 3000 revolutions per minute; the upper part of the crusher is provided with a crusher 2'; the rotating speed of the crusher 2' is 30 to 40 revolutions per minute. When powder cakes are crushed into powder satisfying requirements, the work hardening and the reoxidation can not occur. The utility model can be used for the processing of steel powder.
Description
The utility model relates to the improvement of steel powder production equipment in the metallurgy industry, specifically a kind of iron and steel muffin breaker.
In the production process of steel powder, muffin through high temperature reduction will just can become the powder that meets granularity requirements through broken, in shattering process, require powder can not produce work hardening and reoxidize, and should keep the physical property of similar spongelike structure of powder particle pattern and requirement.At present, the disintegrating apparatus of the steel powder of using is mining disintegrating machine, constitute by motor, housing, screen cloth, broken tup, division board, the shortcoming that the muffin disintegrating machine of this structure exists is: if when the rotating speed of disintegrating machine is higher than 2400 rev/mins, because the internal stress effect between powder, muffin will produce work hardening in shattering process, when if the rotating speed of disintegrating machine is lower than 100 rev/mins, reach the performance of powder requirement, just must take repeatedly broken method, powder will produce in shattering process repeatedly and reoxidize like this.
The purpose of this utility model is to provide the iron and steel muffin breaker that can make muffin not produce work hardening and reoxidize that a kind of broken number of times is few, motor speed is suitable in shattering process.
The utility model is achieved in that this iron and steel muffin breaker is made of motor and disintegrating machine, disintegrating machine comprises housing, tup, separator, rotating shaft and screen cloth, above disintegrating machine, establish a low speed disintegrating machine, the low speed disintegrating machine comprises housing, rotating shaft and reamer, and the low speed disintegrating machine is connected with motor by decelerator.Low speed disintegrating machine rotating speed is 30-40 rev/min, and high speed disintegrator is 3000 rev/mins, and after muffin at first carried out the one-level fragmentation through 30-40 rev/min low speed disintegrating machine, the high speed disintegrator that enters 3000 rev/mins again carried out two-stage crushing.Thereby reduced broken number of times, preferred disintegrating machine rotating speed has overcome broken and has broken once in the journey sclerosis and reoxidize problem.
The utility model has the advantages that muffin when being broken into satisfactory powder, can not produce work hardening and reoxidize.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Accompanying drawing 1 is looked schematic diagram for the utility model master.
Accompanying drawing 2 is that the utility model is along the A-A cross-sectional schematic.
Accompanying drawing 3 is the utility model reamer cross-sectional schematic.
Accompanying drawing 4 is the profile of the utility model tup along vertical axis.
With reference to accompanying drawing 1,2,3,4.This iron and steel muffin breaker, constitute by motor 1 and disintegrating machine 2, disintegrating machine 2 comprises housing 3, tup 4, separator 5, rotating shaft 6 and screen cloth 7, above disintegrating machine 2, establish a disintegrating machine 2 ', disintegrating machine 2 ' comprises housing 3 ', rotating shaft 6 ' and reamer 8, and disintegrating machine 2 ' is connected with motor 1 by decelerator 9.Low speed disintegrating machine rotating speed is 3040 rev/mins, and the high speed disintegrator rotating speed is 3000 rev/mins, and muffin at first passes through 30-40 rev/min after disintegrating machine 2 ' carries out the one-level fragmentation, and the disintegrating machine 2 that enters 3000 rev/mins again carries out two-stage crushing.
As shown in Figure 2, the separator 5 of disintegrating machine 2 and rotating shaft 6 be cast into holistic.
As shown in Figure 4, the tup of disintegrating machine 24 is along being circular-arc perpendicular to a jiao of the cross section of axis, when tup 4 when turning clockwise shown in Fig. 4, the powder that fragmentation goes out is high loose ratio, when being rotated counterclockwise, the powder that fragmentation goes out is for low loose ratio.
