Refer to Fig. 3 and Fig. 4, the structural representation of the ring-roller mill that Fig. 3 provides for the utility model embodiment; Another structural representation of the ring-roller mill that Fig. 4 provides for the utility model embodiment.
The ring-roller mill that the utility model embodiment provides, comprises grinding machine shell 106, drive unit 101, grinding roller 115, the mill 104 being driven by this drive unit 101, and the flour milling of the liner plate 105 of the roll surface of grinding roller 115 and mill 104 forms break-in face.Of the present utility modelly focus on also comprising the scraper 103 being arranged on grinding machine shell 106, on scraper 103, comprise the material scraping plate 102 with horizontal plane with angle.The outline line of the flour milling of liner plate 105 and the angle of vertical curve are 40 °～90 °.As preferably, the outline line of the flour milling of liner plate 105 and the angle of vertical curve are 40 °～75 °, and in the time that this angle is less than 40 °, the production capacity of grinding machine and crush efficiency can decline to a great extent on the contrary.
Scraper 103 can be contained on cover plate 110 by mandrel 107, cover plate 110 is contained on a hole of grinding machine shell 106, pressue device 108 is equipped with in one end of scraper 103, this pressue device 108 can be spring assembly or oil cylinder etc., the left end of pressue device 108 is equipped with cushion block 109, be to be provided with cushion block 109, the gap between capable of regulating material scraping plate 102 and liner plate 105 between the installation end of scraper 103 and cover plate 110.
When drive unit 101 is with after movable grinding disc 104 rotations, material feeds from material inlet 111, material falls into after mill 104, pressue device 116 drives grinding roller 116 to press to corresponding liner plate 105 by rocking arm 112, material drops on mill 104 from material inlet 111 feeds, material moves to the outward flange of mill 104 surroundings under the effect of centrifugal force, mobile material impels grinding roller 115 to be driven rotation by the mill 104 of rotation under the effect of frictional force, determine the angle of material scraping plate 102 according to the character of the angle of liner plate 105 and material, the oblique still right side, a left side of the direction of the angle of material scraping plate 102 tiltedly can determine that quickening material is to mill 104 outward flange translational speeds, or the speed that moves of the material that slows down, in the time that material scraping plate 102 runs into too large material or too thick material and exceedes the precompression of pressue device 108, pressue device 108 will be compressed, at this moment material scraping plate 102 will upwards lift, thereby scraper 103 is protected, after abnormal conditions are got rid of, scraper 103 can be returned to again normal position.
Material constantly rolls under interacting being subject to grinding roller 115 and mill 104, be subject to again the continuous water conservancy diversion of material scraping plate 102 simultaneously, loosen and stir, crossed at the edge of mill 104 by the material after pulverizing, and fall into the annular gap of mill 104 and grinding machine shell 106, there is compressed-air actuated air inlet 120 in the bottom of grinding machine shell 106, a large amount of compressed air is fast rise after entering grinding machine shell 106, zooming air meets after the material after pulverizing, part small particles is brought in mill 104 refaces, too thick particle falls into grinding machine bottom and discharges from coarse fodder outlet 117, granular material is brought into territory, powder-separating area, top 18 by ascending air and is selected powder, qualified fine powder is discharged and is become product from the fine powder outlet 119 of topmost after by territory, powder-separating area 118 together with air, meal falls into mill 104 and regrinds.Because changing, the angle by material scraping plate 102 can regulate and control the translational speed of material on mill 104, so the rotating speed of mill can be increased substantially, having changed Vertical Mill of the prior art so completely all can only move with the slow-speed of revolution, significantly improve like this production efficiency of roller mill etc., the water conservancy diversion of angled material scraping plate 102 to material, the better effects if of loosening and stirring in addition, further improve the crushing effect of grinding roller 115, stirred in addition the fine powder of kicking up in loose process and can be taken away in time by the high velocity air with negative pressure and become product.
It should be noted that, the utility model can not have the territory, powder-separating area 18 on top etc. yet, can join external powder concentrator and carry out fine grinding, also can be applicable in small, broken bits, corase grind etc., be that material is pulverized from the material inlet 111 on top enters mill 104, material after pulverizing is discharged from bottom coarse grain outlet 117, and wherein coarse grain can be regrinded etc. by returning after external classification.
For example, for the angle mill 104 of large (being greater than 80 ° with the angle of vertical curve), material scraping plate 102 can be by the effect of angular transformation (being the angle of the tangent line of the flour milling of the liner plate of scraper plate and mill) by material to mill 104 center water conservancy diversion, with the speed of service of the material that slows down, increase material thickness and increase grinding roller and roll number of times; Also can allow the material of compacting be loosened and stir simultaneously, make the better effects if rolling, and stir and loose process in brought grinding machine top with the high velocity air of negative pressure when a part of fine powder that kick up in more ahead of time by mill and become in advance product, the effect of pulverizing has been drained and further improved to fine powder in time, can make like this material each time by mill time, its fineness is higher, thereby output is also high.
For example, for the angle mill 104 of little (being less than 45 ° with the angle of vertical curve), because the centrifugal force component producing is less, material is difficult to leave mill 104, thereby therefore can material be left to mill as early as possible by the angle of conversion material scraping plate 102, be material scraping plate 102 by himself angle by material to the outside water conservancy diversion of mill 104, that is to say and increase the movement velocity of material on mill 104, the angle of the material scraping plate 102 that therefore now the angle of the angle of material scraping plate 102 and the liner plate of mill is large is contrary, its movement velocity of material in the little liner of mill 104 upper angles is slower, this is just need to accelerate its movement velocity by material scraping plate, thereby controlling artificially it moves in the most rational scope, in controlling translational speed, the material being compacted is obtained repeatedly loose and stirs, such crushing effect can be better.
For the mill 104 of same angle, in the time that its rotating speed is higher because its centrifugal speed can strengthen, the angle of material scraping plate 102 also should have big or small variation or even angle direction have anti-and suitable change.Different materials, different granularities or different water content, its movement velocity on mill 104 all can change, this will have influence on its output, energy consumption and product granularity, adopt different angles material scraping plate can to its movement velocity and pulverize time situation adjust significantly and improve.
Refer to Fig. 9 and Figure 10, the structural representation of the scraper that Fig. 9 provides for the utility model embodiment; The structural representation of the scraper that Figure 10 provides for another embodiment of the utility model.
In the utility model one specific embodiment, the angle of inclination of each material scraping plate 102 on same scraper 103 is identical.Fig. 9 and Figure 10 are the structural representations of two kinds of scrapers 103, other are all consistent for this two kinds of scrapers 103, only have the angle of its material scraping plate 102 contrary, two groups of material scraping plates 102 all have the angle of different angles with the tangent line of the flour milling of the liner plate 105 of mill 104, and the angle of the inclination of the material scraping plate 102 of every kind of scraper 103 is all towards two different directions.According to mill 104 turn to or clockwise turns or when anticlockwise turning, same material scraping plate 102 in use, can be on mill 104, to promote material to move to mill 104 center, slow down the outer speed of moving of material, in the time changing the rotation direction of mill 104, this same material scraping plate 102 is transformed into again accelerates the speed that material moves to outer rim at mill 104.
Refer to Figure 11, Figure 11 is the structural representation of the utility model scraper that an embodiment provides again.
The direction of the angle of each material scraping plate 102 on same scraper 103 is all different.Material scraping plate 102 on this kind of material scraping plate device 3 is that with the difference of Fig. 9 and Figure 10 its material scraping plate 102 and the angle direction of the tangent line of the flour milling of the liner plate 105 of mill 104 are not directions, but there are two kinds of directions, for example, in the time that mill 104 rotates, on this scraper 103, the material scraping plate 102 of different directions angle can promote the edge to mill 104 in a segment distance of the material on mill 104, to accelerate the translational speed of material; And in a rear segment distance, be that material promotes material while leaving mill soon to mill 104 center, with the translational speed of material on mill 104 that slow down.Can control better so best translational speed and the thickness of feed layer of material, can play the effect of better loosening and stirring to the bed of material in addition, thereby improve crushing process.
