Description
Technical field
A kind of multilayer planet roller mill of the utility model belongs to powder attrition process apparatus field.
Technical background
More representational mill types has following several kinds at present:
1 Raymond mill class: mill tube (dish) is fixing, and individual layer roller frame drives the grinding roller rotation, simultaneously grinding roller own because of with mill tube (dish) rubbing action autobiography.Material is rolled fragmentation.The levigate difficulty of its core powder.
2, MPS (middling speed) grinding machine class: individual layer grinding roller frame is fixed, and mill tube (dish) rotation friction simultaneously drives the grinding roller rotation.Material rolls fragmentation because of centrifugal action motion from inside to outside in mill tube (dish) through grinding roller.
3, ball mill class: fall after the cylindrical shell rotation is taken steel ball to certain altitude, object is produced the effect of impacting and grinding.Critical speed of mill is low, can't improve rotating speed.
Existing above-mentioned all types of grinding machines exist abrasive dust efficient low, and power consumption is big, capacity usage ratio is low, and problem such as build heaviness.
The utility model content
The purpose of the utility model provides a kind of multilayer planet roller mill, to improve the abrasive dust operating efficiency of grinding machine, reduces the material escapement ratio, saves power consumption, and compact conformation.
The purpose of the utility model realizes through following technical scheme:
A kind of multilayer planet roller mill of the utility model comprises frame, central rotating shaft, hollow rotating shaft, mill tube, grinding roller frame and grinding roller, and characteristics are that mill tube is fixedly connected with hollow rotating shaft; The grinding roller frame is the multilayer link through space collar or direct axially spaced-apart setting; The multilayer link radially evenly is arranged at intervals with connection chain and grinding roller active link, and central rotating shaft passes grinding roller frame central axis and is fixedly connected with it, and its central rotating shaft is inserted in the hollow rotating shaft; Overall co-ordination is arranged in the mill tube; And the central lines of two rotating shafts, central rotating shaft, hollow rotating shaft are installed on the frame through bearing respectively, are connected with power set respectively; Make relative backward rotation; Be that central rotating shaft drive grinding roller frame rotates with mill tube in mill tube in opposite directions, grinding roller rotates in mill tube with the grinding roller frame, and under centrifugal action and between the mill tube inwall, material is rolled fragmentation.
Above-mentioned multilayer link is two-layer at least.
At least two of the connection chains that above-mentioned multilayer link radially evenly is provided with at interval.
The spaced radial angle of the connection chain of adjacent two layers link is by formula confirmed n in the formula in 360 degree/(2 * 4) under on the above-mentioned multilayer frame
1Be the link number of plies, n
2Number for the activity chain of every layer of link.
Above-mentioned through the rack-mounted hollow rotating shaft of bearing and its interior central rotating shaft level of suit or vertically setting.
The design's grinding roller rotates in mill tube with the grinding roller frame through active link, i.e. revolution, and under centrifugal action, form outward pressure and act on the mill tube wall, because of with the frictional force effect rotation of reverse rotation mill tube wall, and formation planetary structure; On the one hand material with its rotation, makes material be evenly distributed on the mill tube inwall in mill tube, grinding roller the grinding roller frame drive down and with the frictional force effect of reverse rotation mill tube under the higher speed of the relative mill tube of acquisition, help improving the grinding efficiency of material; The multi-level grinding working face that the grinding roller of layer link institute active link and mill tube form more than the grinding roller frame on the other hand improves the improved grinding operating efficiency comprehensively; Simultaneously, because of each layer link grinding roller distribution angle is different, thereby reduced the escapement ratio of material.Therefore the utility model design grinding efficiency is high, and the powder escapement ratio is low, and energy consumption is low, and compact integral structure, effectively utilizes the usage space of production scene more.

The specific embodiment
Combine accompanying drawing at present, further specify the utility model and how to implement:
The utility model multilayer planet roller mill comprises frame, central rotating shaft, hollow rotating shaft, mill tube, grinding roller frame and grinding roller.
The design's grinding roller frame is the multilayer link that axially spaced-apart is provided with, and every layer of link spaced radial can be provided with a plurality of connection chains, each connection chain respectively with the grinding roller active link.
It is example that existing grinding roller frame with two-layer link, every layer of link are provided with the grinding roller that four connection chains connect through spaced radial respectively, further specifies the enforcement of the utility model.(like Fig. 1,2,3)
When the utility model multilayer planet roller mill is worked; This mechanomotive force transmission system F is transferred to central rotating shaft 1 and hollow rotating shaft 2 with counter-rotational power respectively; Make central rotating shaft 1 and hollow rotating shaft 2 make rightabout and rotate, mill tube 3, grinding roller frame 4 are promptly made backward rotation with hollow rotating shaft 2, central rotating shaft 1 respectively, and grinding roller 5 rotates with grinding roller frame 4 through active link 4-a; I.e. revolution; And under centrifugal action, produce outside pressure and act on mill tube 3, with the frictional force effect of mill tube 3 under rotation, form planetary structure; Because grinding roller frame 4 is opposite with the rotation direction of mill tube 3, grinding roller 5 obtains high rotational velocity under the frictional force effect, forms multiple layer high speed jointly with mill tube 3 inwalls and grinds working face.Simultaneously; Material gets in the mill tube 3 from charging aperture I; Rotate under the action of centrifugal force that produces owing to mill tube 3 and to be evenly distributed on mill tube 3 inwalls, it is levigate in the separate working face of the multilayer of grinding roller 5 and 3 formation of mill tube, to be broken, and the finished product materials after levigate is discharged from discharging opening II.This design make improved grinding more evenly, to grind operating efficiency higher.
The utility model is used for producing when implementing; Can select different roller mill parameters with the powder processing request based on the raw material situation; Can select to use grinding roller frame and grinding roller to cooperate installation with mill tube, form the multiple layer high speed that conforms with demand between grinding roller and the mill tube of its active link and grind working face and grind operating efficiency thereby make by the different numbers of plies, different connection chain numbers.
