Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
Manufacture of cement raw material vertical-grinding, main working parts are mill and grinding roller.Motor passes through decelerator band movable grinding disc
Rotate, grinding roller rolls on mill around Pivot Point Center.Material falls on mill center by lock feeding device through emission of baiting chute, by
Annular material bed is formed in the effect of centrifugal force, and is entered by pincers between grinding roller and mill, effect is squeezed and is crushed, and due to
Relative slide produces shearing force, makes material levigate.
Vertical Mill top is passed through hot-air from lower side, material is dried with powder equipment is selected.In the inertia of mill
Under centrifugal action, overflowed by the material of grinding from mill edge, kicked up to separator and be classified by high velocity air, coarse powder returns
Mill is returned again by grinding（Referred to as interior circulation）, it is outer that fine powder then takes mill to by air-flow.The coarse granule not taken up by hot-air
Material, powder concentrator fed by bucket elevator again after overflowing mill, extrudes grinding again（Referred to as outer circulation）.
Manufacture of cement raw material vertical-grinding of the present utility model, there is the Vertical Mill similar or identical with above-mentioned entirety routinely to tie
Structure.Though not illustrating the overall structure of Vertical Mill in Fig. 1 and Fig. 2 completely, those skilled in the art are used as, understanding can't be produced
On puzzlement.
Raw material vertical-grinding of the present utility model is with traditional structure difference：Rotatable mill 1 and on mill 1
Grinding roller 2, be additionally provided with the flitch 3 for the bed of material on mill to be stirred, its structure such as Fig. 1 in the milling zone of mill 1
Shown in shown and Fig. 2.Flitch 3 can be the single plate body structure for being stirred the bed of material by the rotary course of mill 1, also may be used
Think that be driven by drive device can driving structure and what is stirred to the bed of material.
In the present embodiment, as depicted in figs. 1 and 2, flitch 3 is the grinding for being radially arranged and covering mill 1 along mill 1
Area so that the bed of material of milling zone can be stirred in the length of whole flitch 3, improve the operating efficiency of flitch 3.
In the present embodiment, flitch 3 is fixed setting, is so advantageous to simplify global design, avoids in raw material vertical-grinding
It is upper to introduce excessive complicated mounting structure.
In a specific embodiment, flitch 3 is the outer rim entrance from mill 1, is radially arranged along mill 1 and covers mill 1
Milling zone, such design method can at utmost avoid flitch 3 from producing shadow to this body structure and drive mechanism of Vertical Mill
Ring or interfere, also allow for the assembling and fixation of flitch 3, there is the advantages of simple for structure, cost is cheap.
As the further design of above-mentioned embodiment, the outer end of flitch 3 is fixed on outside mill 1 in another embodiment
On the grinding machine shell 4 of side so that Vertical Mill does not design the special fixed structure of flitch 3 in itself, and is fixed using grinding machine shell 4, tool
There is the advantages of simple for structure.
As the further design of middle flitch 3, flitch 3 is divided into the first plate body along its length in another embodiment
31 and second plate body 32, first plate body 31 be fixedly installed on vertical mill casing 4, the plate body 31 of the second plate body 32 and first
Between detachably link, second plate body 32 covers the milling zone of mill 1.The design of first plate body 31 and the second plate body 32 is favourable
In carrying out independent selection and manufacture to support section and stirring part, while design for disassembly can easily carry out the second plate body
32 replacing, improve flexibility and the convenience of maintenance.
Under the structure design of the first plate body 31 and the second plate body 32, the first plate body 31 and the second plate in another embodiment
Body 32 is detachably connected the outer fringe position for being a little located at mill 1, such optimization being designed with beneficial to stress, turn avoid removable
Tie point is unloaded to be located in milling zone and impact process of lapping and stirring process.
On the circumference of whole mill 1, multiple flitch 3 are distributed with as shown in Figure 2, its objects and advantages is improved to material
The efficiency that layer stirs.The flitch 3 is distributed between two grinding rollers 2, is so advantageous to avoid flitch 3 from producing interference to grinding roller 2, is protected
Demonstrate,prove the safety that flitch 3 designs.
Specifically, in the design of flitch 3 of plate body structure, the bottom of flitch 3 is adapted with the shape of mill 1, i.e. flitch 3
The arc of bottom be to be adapted with the arc of the bottom of mill 1.After flitch 3 installs, flitch 3 not with the bottom phase of mill 1
Contact, that is, the structure that whole flitch 3 is suspended on mill 1 is showed, flitch 3 has 5-15mm spacing with mill 1, to ensure
The effect that the bed of material stirs, while avoid flitch 3, mill 1 and the bed of material in real work from producing interference and produce larger resistance
Power, so that hindering the grinding of the bed of material and making flitch 3 bear excessive power and reduce its reliability.
In another embodiment, the height of flitch 3 is 50-150mm, and actual experiment shows, the flitch under the height,
It stirs that effect is more excellent to the bed of material, and the reasonable stress of flitch 3 and the rotary course of mill 1 is influenceed relatively low.
The steel that flitch 3 can use 30-70mm thick are made, and make it have preferable durability.
After the structural materials of traditional Vertical Mill form stable, the thicker bed of material on mill, part fine granular materials can ground
Cushion is formed on disk, causes grinding roller to reduce the mechanical efficiency of material, also mill load is increased, electric current is higher.Pass through
In the flitch that the milling zone of mill is provided for being stirred the bed of material on mill so that material is secondary to be stirred and kick up, energy
Effectively avoid fine granular materials from forming cushion on mill, avoid the formation of " backing strap ", reach increase grinding machine grinding efficiency,
Strengthen grinding machine acting, reduce the effect of mill load.
In actual experiment, the electric current 85-110A of grinding machine before improvement, unit power consumption 8.3kw.h/t, platform yield 145t/h, this
Grinding machine electric current 67-85A, unit power consumption 6.5kw.h/t, platform yield 165t/h after utility model patent improves.It can be seen that the flitch
Design the raising to grinding machine grinding efficiency, enhancing, the reduction of mill load of grinding machine acting serve positive and significant effect.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
