Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Embodiment
As Fig. 1, 2, shown in 3, a kind of Novel hammer piece crusher rotor, it includes main shaft 1, bearing 2, end face hammer leaf dividing plate 11, middle hammer leaf dividing plate 10, hammer leaf 9, 1# bearing pin 8, 2# bearing pin 14, 1# spacer 6, 2# spacer 7, 3# spacer 15, main shaft 1 is fixed on pulverizer bearing plate by bearing 2, pulverizer bearing plate welds with pulverizer wallboard 12, end face hammer leaf dividing plate 11 and middle hammer leaf dividing plate 10 are by 2# spacer 7, 3# spacer 15, 2# bearing pin 14 affixed one-tenth entirety, wherein: end face hammer leaf dividing plate 11 is positioned near pulverizer wallboard side, namely, end face hammer leaf dividing plate 11 is positioned at the main shaft two ends of pulverizing chamber, middle hammer leaf dividing plate 10 is between end face hammer leaf dividing plate 11, that is, middle hammer leaf dividing plate 10 is positioned in the middle of the main shaft of pulverizing chamber.Above-mentioned securing member can but be not limited to holding screw 13.Be provided with flat key 16 between above-mentioned entirety and main shaft 1, so, main shaft 1 can drive above-mentioned integral-rotation.Above-mentioned overall two ends can be fixed on main shaft 1 with round nut 3 and floor clip 4, and hammer leaf 9 is arranged between hammer leaf dividing plate by 1# bearing pin 8,1# spacer 6 and sleeve 5.Main shaft 1 one end is connected with pulverizer motor by shaft coupling or belt transmission.Above-mentioned middle hammer leaf dividing plate 10 is selected has protuberance and axisymmetric middle hammer leaf dividing plate, and as shown in Figure 1, middle hammer leaf dividing plate 10 is the middle hammer leaf dividing plate of square preferably, and it has multiple 1# protuberance 17a.Separately, middle hammer leaf dividing plate 10 preferentially adopts 45# steel, middle hammer leaf dividing plate 10 preferred thickness >=6mm.Above-mentioned end face hammer leaf dividing plate 11 is also selected has protuberance and axisymmetric end face hammer leaf dividing plate, and as shown in Figure 1, end face hammer leaf dividing plate 11 is preferred square end faces hammer leaf dividing plate also, and it also has multiple 1# protuberance.Separately, end face hammer leaf dividing plate 11 also preferentially adopts 45# steel, end face hammer leaf dividing plate 11 preferred thickness >=8mm.Separately, end face hammer leaf dividing plate 11 and middle hammer leaf dividing plate 10 are installed the internal surface of hole heat treatment of 1# bearing pin 8, hardness HRC50-55.
In actual use procedure, as shown in Figure 3, middle hammer leaf dividing plate 10 also can adopt the middle hammer leaf dividing plate of the polygon with multiple 2# protuberance 17b, and it has axially symmetric structure.End face hammer leaf dividing plate 11 also can adopt end face hammer leaf dividing plate in the polygon with multiple 2# protuberance, and it has axially symmetric structure.
During normal work, pulverizer motor drives rotor mill High Rotation Speed by shaft coupling or belt transmission, the arrangement diameter of bearing pin on hammer leaf dividing plate is φ c, so, hammer leaf 9 synchronous high-speed under the effect of hammer leaf dividing plate and 1# bearing pin 8 rotates, the top linear velocity of hammer leaf 9 can reach 80-115m/s, crashed under the effect of hammer leaf 9 after material enters pulverizing chamber, split into the less particle that differs in size, reach the particle of fineness through screen cloth, the particle not reaching fineness is again clashed into by hammer leaf 9 in screen cloth, along with the continual charging of pulverizer, the material not reaching fineness in screen cloth in pulverizing chamber gathers together, form circulation layer.End face hammer dividing plate 11 of the present utility model and middle hammer dividing plate 10 are designed to have protuberance and axisymmetric shape.For square, as shown in Figure 1, in the middle of square, the catercorner length of hammer leaf dividing plate is L, L is generally equal to or less than original circular hammer leaf dividing plate diameter, foursquare four protuberances are High Rotation Speed in the scope of middle hammer leaf dividing plate drift angle rotating diameter or end face hammer leaf dividing plate drift angle rotating diameter φ b, under the effect of dividing plate 10 4 protuberances hammered into shape by end face hammer dividing plate 11 and centre, stirring is played to material, the effect stirred, the circulation layer formed in screen cloth is broken ring to a certain extent, increase the probability that material is smashed again by hammer leaf 9, the material hit externally flies, to rub further, the effects such as shearing, and further breaking material circulation layer, improve crush efficiency, reduce energy consumption.In actual use procedure, use after the utility model, hammer leaf 9 also can lengthen, the volume of pulverizing chamber in corresponding increase screen cloth, is more conducive to penetrating of negative-pressure air-flow in pulverizing chamber, improves the probability of the material in screen cloth through screen cloth, improve pulverizer output.
The utility model is not limited to above-described embodiment, and the technical scheme that all employings are equal to or equivalence replacement is formed all falls into the protection domain that the utility model requires.
