Abstract
The utility model relates to a novel centrifugal impact crusher rotor, comprising an upper and a lower cover plates. Blades and hard blocks are arranged between the upper and the lower cover plates, wherein, the hard block is arranged at the external port of the blades. A hub and a distribution cone are respectively connected with the lower cover plate. The number of the material channels made of the blades and hard alloy is 4-6. The utility model has the advantages that the optimum value of obtaining the rotor passage is 4-6, resulting in uniform material distribution without shock; the rotor adopt an integral cast structure; the material is made of wear resistant alloy, and therefore, the wear resistance and the integral rigidity is high, which ensures long service life and stable operation.
Description
The utility model relates to a kind of novel centrifugal impact grinding machine rotor.
Existing centrifugal impact crusher rotor structure is seen Fig. 3, and this rotor is made up of upper cover plate 1, lower cover 2, material distributing cone 3, blade 4, side plate 5, and it has three material channels, adopts common broken steel welded-steel plate construction, brings following point thus:
1, because of adopting triple channel, its passage distributes and too becomes estranged, and causes material inequality between the passage easily and the generation vibration, and this kind vibration can't normally move machine even as big as destroying Equipment Foundations;
2, adopt the general steel plate welding, though manufacturing process is simple, general steel plate can't bear high speed impact and wearing and tearing, and rotor life is extremely short.
3, when design, the restraining factors of the rotary inertia of rotor had not been considered to the material skewness.
The purpose of this utility model is the problem at above-mentioned existence, proposes a kind of novel centrifugal impact grinding machine rotor, thereby can effectively overcome the defective that prior art exists.
Technical solution of the present utility model:
It includes upper and lower cover plate 2,6, between upper and lower cover plate 2,6, blade 5 and hard block 1 are arranged, hard block 1 wherein is located at the external port of blade 5, and wheel hub 3 is connected with lower cover 6 respectively with material distributing cone 4, and blade 5 and the material channel that is made of the hard block 1 that carbide alloy is made are the 4-6 bar.
Upper cover plate 2, blade 5, lower cover 6 are whole antifriction alloy cast structure.
The integral thickness of lower cover 6 or edge thickness all are 2-6 times of upper cover plate 2.
The external port of blade 5 is hard alloy blocks.
Advantage of the present utility model:
1, according to the scope of material handling size and the diameter of rotor, by calculating and test, the optimum value that obtains rotor channel is 4-6, in this scope, can not become estranged, and cause the material skewness because of channel arrangement, produce vibration, also not can because of passage by the overstocked putty that causes of row;
2, rotor adopts the monoblock cast structure, and material is an antifriction alloy, and its wearability and integral rigidity are considerably beyond the general steel plate Welding Structure;
3, because the linear velocity maximum of blade outer end, so material is also maximum to the impact and the wearing and tearing at this position, so increased especially in the rotor punching outer end than blade material hard the hard alloy blocks of Duoing, make increase substantially the service life of rotor;
4, rotor lower cover thickness or its edge thickness are multiplied, its purpose is to increase the rotary inertia of rotor, play the effect of flywheel, thereby the eccentric moment that produces of material skewness compares with the rotary inertia of rotor integral body then insignificantly, guaranteed that equipment operation is steady.
In sum, novel rotor solved centrifugal in the past impact crusher vibration equipment greatly can't operate as normal and this two large problems of rotor quick abrasion.Make this kind equipment can give full play in the disintegrating process of cement pottery chemistry and metallurgical mine that its ability is big, the steel consumption is little, characteristic of low energy consumption.
Accompanying drawing 1 is an example structure schematic diagram of the present utility model, is 4 passages among the figure;
Accompanying drawing 2 is that cuing open of Fig. 1 shown structural representation;
Accompanying drawing 3 is prior art structural representations;
Contrast Fig. 1, Fig. 2 further describe major technique solution of the present utility model:
Centrifugal impact grinding machine rotor described in the utility model is used to pulverize the following hard ware material of diameter 100mm.Its structure as shown in Figure 1, it is made up of hard block 1, upper cover plate 2, wheel hub 3, material distributing cone 4, blade 5, lower cover 6, upper cover plate, blade and lower cover are overall structure, all the other are all by bolt or be welded to connect.
The space that is constituted between the upper and lower cover plate is divided into some passages by blade, material enters rotor by in the middle of the upper cover plate, and along blade movement, material passes through passage rapidly under centrifugal action under the guide effect of material distributing cone, throw away with high speed, realize the purpose of impact grinding.
