Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the thin flour mill of this centrifugal superelevation, comprise the upper machine body 17 that links to each other successively from top to bottom, middle body 18 and lower body 4, lower body 4 is provided with equally distributed fresh air inlet, on the base plate 3 of lower body 4 main shaft 2 is housed, the belt pulley 1 of main shaft 2 lower ends is positioned at base plate 3 belows, columnar mill 5 is positioned at lower body 4, on mill 5 inwalls wear ring 27 is housed, on the middle body 18 hopper 6 is housed, in the middle body disintegrating mechanism is housed, comprise at least three grinding roller assemblies in the disintegrating mechanism, classification mechanism is housed in the upper machine body, and the exhausting hole 10 on the upper machine body communicates with the fine powder trapping system, and mill 5 is contained in main shaft 2 upper ends, grinding roller 28 is contained on the grinding roller axle 23 in each grinding roller assembly, have grinding roller frame 22, grinding roller frame 22 to be hinged on the middle body outside the grinding roller axle 23, pressing mechanism is packed on the middle body, pressing mechanism is hinged by pressuring shaft 26 and grinding roller frame 22, in middle body upper support 7 is housed, pressure limiting mechanism one end and support 7 are hinged, and the other end is hinged by pressure limiting axle and grinding roller frame 22.
Pressure limiting mechanism comprises pressure limiting axle 21, and pressure limiting axle 21 is positioned at pressure limiting axle sleeve 19, and extension spring 20 is housed in the pressure limiting axle sleeve 19, and pressure limiting axle 21 links to each other with extension spring 20, and pressure limiting axle sleeve 19 is hinged with support 7; Pressing mechanism comprises pressuring shaft 26, and pressurization axle sleeve 24 is arranged outside the pressuring shaft 26, on the body 18, in the pressurization axle sleeve 24 spring 25 is housed during pressurization axle sleeve 24 is contained in, and pressuring shaft 26 links to each other with spring 25.
Classification mechanism comprises grading wheel 9, grading wheel 9 is packed on the classification axle 8, classification axle 8 is fixing by upper support frame 11 and lower support frame 16, classification axle 8 upper ends link to each other with motor, grading wheel 9 comprises superposed ventilative dish 12 and is positioned at the positioning disk 15 of bottom, the diameter of ventilative dish 12 is greater than the diameter of positioning disk 15, graded blade 14 two ends are contained in the edge of ventilative dish 12 and positioning disk 15 respectively, the number of graded blade is no less than 60, and the blade 13 that keeps out the wind that is the level of state is housed in the upper end of each graded blade.
Because classification axle 8 is fixing by upper support frame 11 and lower support frame 16, this just can guarantee the stability of its rotation, and makes grading wheel 9 can reach high rotational speed, thereby improves the fineness of product.
Operation principle of the present utility model is: the mill 5 of motor drives main shaft 2 upper ends rotates, grinding roller 28 is being close under the effect of pressing mechanism on the wear ring 4, and do passive rotation, when material enters mill by hopper 6, because action of centrifugal force, material outwards throws away and enters between grinding roller 28 and the wear ring 27, by the pulling force of pressing mechanism to grinding roller, finishes material grinding.Because the material size is inhomogeneous, grinding roller 28 can be that swing in perpendicular in the center of circle with the jointed shaft of grinding roller frame 22 and middle body, when grinding roller breaks away from wear ring, pressuring shaft 26 can be returned to the state of being close to wear ring by the pulling grinding roller under the effect of spring 25, and because the effect of extension spring 20 in the pressure limiting mechanism, can slow down the bump dynamics of grinding roller to wear ring, thus the vibrations that alleviate complete machine, and can prolong service life of grinding roller and wear ring.
Meanwhile, driven by motor classification axle 8 and and then drive grading wheel 9 high speed rotating, dust under the effect in exhausting hole 10 therefrom body 18 enter upper machine body 17, and be adsorbed on the graded blade of high speed rotating, because action of centrifugal force, big particle is thrown on the sidewall of upper machine body, and little dust granules passes the air-permeating hole on the slit between graded blade and the dish that lets in air, and enters the fine powder trapping system by exhausting hole 10 at last.The blade 13 that keeps out the wind that rotates in horizontal plane can produce downward wind-force, stops that dust granules enters the exhausting hole from the space between ventilative plate edge and upper machine body, thus the fineness of the product that assurance is collected.
