Abstract
The utility model discloses a centre round pipe type vibromill, which is a mechanical device used for milling materials and preparing material granules. Because an 'insert zone ' is formed in the center of a milling cylinder during the vibration of the milling cylinder, the efficiency of milling is low. A horizontal center circular tube is arranged at the position of the 'insert zone', thus reaching the goal of eliminating the center 'inert zone', and besides, because the limit and the bounce of the center circular tube to grinding mediums, the grinding mediums are subjected to the impact more than once in a vibration period, activating the motion state of the mediums, and enlarging the impact energy of the mediums to milled materials, thus reaching the goal of increasing the fitness of milling, increasing the efficiency, and decreasing the energy consumption.
Description
Center circle tubular type vibromill.Relate to the material grinding technology, carry out a kind of plant equipment of material granule preparation.
The mill tube of existing vibromill, the grinding dimensional energy distribution is inhomogeneous, and this is the not high main cause of existing vibromill mill efficiency.When mill tube produced vibration under the eccentric activator effect, mill tube was that the equilbrium position is done circular or the vibration of ellipse garden shape track with the mill tube center.Mill is situated between and presses the circular concentric hierarchal arrangement on the mill tube cross section, and it is except that doing also to make spinning motion the revolution along garden week; In addition, the mill spring repeatedly that is situated between makes the mill group that is situated between be " boiling " state, by grind material granule ground Jie mutual impact, grind and shell and pulverize.But.This percussion is to decay gradually to the mill tube center from the mill tube wall, thereby the impact strength of mill between interlayer also reduce to the mill tube center gradually by the mill tube wall, forms in " central inertia district ", has weakened the effect of pulverizing, and has reduced the efficient of grinding.
The purpose of this utility model is to cancel or to dwindle " the central inertia district " that the mill tube center produces when vibration, activates the grinding media movement state, and the grinding dimensional energy distribution is reached unanimity, and is situated between to being ground the mill efficiency of material to improve mill.
In order to achieve the above object, designed a kind of vibromill that is used for the center circle tubular type of material granule grinding, it is to constitute like this: at the mill tube central authorities installing one horizontal center pipe of vibromill, to replace the position in " central inertia district ".Center pipe diameter and mill tube diameter ratio are 1/3～1/4.
Advantage of the present utility model is: at mill tube central authorities installing one horizontal center pipe, and " the central inertia district " that occurs in the tube when it can not only cancel the mill tube vibration, and can also activate the motion state that mill is situated between, increase the impact energy that mill is situated between in the mill tube.When producing vibration under the effect of mill tube at eccentric activator, the mill course tube wall skin in the mill tube that is situated between respectively transmits energy by the outer course barrel internal layer of tube wall simultaneously, has realized the bi-directional energy, makes the grinding dimensional energy distribution be tending towards even.Because the center pipe is to the restriction and the bounce-back of grinding media movement, make and grind the impact that is situated between more than in a vibration period, being subjected to once, so just activated the motion state that mill is situated between, increased mill and be situated between, thereby reached the purpose that improves grinding fineness and efficient the impact energy and the mill stripping effect of quilt mill material.
With 30 liters of vibromills, grinding standard quartz sand is example, and it is 18000cm that common mill tube vibratory milling obtained specific area value (Bo Shi value) in 200 minutes
2/ g generally is no more than 20000cm
2/ g; And adopting vibromill of the present utility model, grinding 160 minutes can reach 24263cm
2/ g.
Accompanying drawing is the utility model embodiment schematic diagram, in conjunction with the accompanying drawings the utility model is further described.

Fig. 2 the utility model schematic diagram
The utility model organic frame 1, support spring 2, discharging opening 3, charging aperture 4, mill tube 5, shaft coupling 6, motor 7, eccentric activator 8. At mill tube 5 central authorities installing one horizontal center pipes, and the ratio of the diameter d in garden, center 9 and mill tube diameter D is 1/3～1/4. The length of center pipe is identical with the length of mill tube.
