Description

一种单板翻击式破碎机及其破碎方法Single-plate tumbling crusher and crushing method thereof 技术领域Technical field
本发明属于破碎机技术领域，具体涉及一种单板翻击式破碎机及其破碎方法。The invention belongs to the technical field of crushers, and particularly relates to a single-plate tumble crusher and a crushing method thereof.
背景技术Background technique
反击式破碎机是中细碎设备，是对破碎的成品粒径具有整形功能的机型；即破碎后的成品颗粒接近圆颗粒体，且菱角削除。就其“破碎兼整形功能”这一综合性能而言，远优于同类破碎功能的圆锥破碎机或颚式破碎机。The impact crusher is a medium-fine crushing device, which is a model that has a shaping function for the particle size of the crushed product; that is, the crushed product particles are close to round particles and the rhomboids are removed. As far as its comprehensive performance of "crushing and shaping function" is concerned, it is far superior to cone crushers or jaw crushers with similar crushing functions.
反击式破碎机的板锤和转子刚性连接，板锤一般设有多个，大小相同，各板锤的两端均对齐，反击式破碎机内设有反击板，反击板组合形成破碎腔，物料在重力作用下从进料口落入破碎腔内并落向板锤，板锤随转子高速转动通过其侧部的撞击面撞击物料，将物料抛射到反击板上进行破碎，随后物料受到重力和反弹力再次撞击板锤，板锤对其进行再次抛射破碎，重复多次，物料最后达到所需的粒径厚从出料口落出。The hammer of the impact crusher is rigidly connected to the rotor. There are generally multiple hammers of the same size. The two ends of each hammer are aligned. The impact crusher is equipped with impact plates. The impact plates are combined to form a crushing cavity. Under the action of gravity, it falls from the feed port into the crushing cavity and falls to the hammer. The hammer is rotated at high speed through the impact surface on the side to hit the material, and the material is thrown on the impact plate for crushing. Then the material is subjected to gravity and The rebound force hits the plate hammer again, and the plate hammer throws and crushes it again and again, and the material finally reaches the required particle size and falls out of the discharge port.
转子速度越快，破碎效率越高，但是当转子在高速转动的时候，由于多个板锤的转动空间重合，因此在相同转速情况下，板锤越多，相邻两个板锤经过同一个位置的时间越短，而随着转子速度的提高，这个时间会越来越短，最终会造成物料来不及落到板锤的撞击面上，只能与板锤外周发生摩擦接触后被带走，从而无法与板锤的撞击面的产生撞击，板锤与转子组合形成类似一高速运转的“砂轮”，对物料形成“磨”的作用，不仅对物料没有击打作用，造成物料没有足够有效的撞向反击板的速度，大大影响破碎效果，且板锤外周受长期的磨削作用，磨损严重；如果降低板锤速度，虽然物料有足够的时间落地板锤的撞击面上，但如果板锤速度太慢，不能与物料进行高速撞击，同样不能使物料具有足够有效的撞向反击板的速度。The faster the rotor speed, the higher the crushing efficiency, but when the rotor is rotating at high speed, because the rotation spaces of multiple plate hammers coincide, the more plate hammers are at the same speed, the two adjacent plate hammers pass the same The shorter the position, the shorter the time as the rotor speed increases. Eventually, the material will not fall on the impact surface of the hammer and can only be taken away after frictional contact with the periphery of the hammer. As a result, the impact with the impact surface of the hammer cannot be caused. The combination of the hammer and the rotor forms a high-speed "grinding wheel", which forms a "grinding" effect on the material, not only does it not impact the material, but the material is not sufficiently effective. The speed of impacting the impact plate greatly affects the crushing effect, and the outer periphery of the plate hammer is subject to long-term grinding, causing severe wear; if the speed of the plate hammer is reduced, although the material has enough time to fall on the impact surface of the floor hammer, if the plate hammer The speed is too slow to hit the material at high speed, nor can it make the material have sufficient speed to hit the impact plate.

发明的有益效果The beneficial effects of the invention
有益效果Beneficial effect
与现有技术相比，本发明的有益效果在于每个旋转盘有且只有一个板锤，即各板锤的转动空间不重合，各旋转盘一个转动周期内有且只有一个板锤对物料进行击打，可以在保证板锤转速的同时使物料具有足够的时间落在板锤的撞击面上与其进行高速撞击，且转子总成的转速还可以得到大幅提高；当板锤设置多个时，板锤的尺寸相对现有的板锤大幅缩小，击打力更强，破碎效果更好。Compared with the prior art, the present invention has the beneficial effect that each rotating disk has one and only one plate hammer, that is, the rotation spaces of the respective plate hammers do not coincide, and there is only one and one plate hammer for each rotating disk to perform material processing. Hitting, while ensuring the speed of the hammer, allows the material to have enough time to fall on the impact surface of the hammer for high-speed impact with it, and the speed of the rotor assembly can also be greatly increased; when multiple hammers are installed, Compared with the existing hammer, the size of the hammer is greatly reduced, the impact force is stronger, and the crushing effect is better.

When there are at least two rotating disks 2, the rotating disk 2 may be a split structure or an integrated structure. The rotating shaft 4 rotates at a high speed under the driving of the driving mechanism.
旋转盘2的数量可以根据实际需求设置，但需同时要保证转子总成的平衡，即转子总成的重心位于其转动中心线上，即转轴4的轴线上，这样设置的目的是为了保证转子总成运动的平稳。The number of rotating disks 2 can be set according to actual needs, but at the same time, it is necessary to ensure the balance of the rotor assembly, that is, the center of gravity of the rotor assembly is located on the center line of its rotation, that is, the axis of the rotating shaft 4. The purpose of this setting is to ensure the rotor The smooth movement of the assembly.
实施例1：Example 1:
如图2所示，旋转盘2设有一个，相对的板锤3也只设有一个，为保证转子总成的转动平衡，使转子总成的重心位于转轴4的轴线上，可以在旋转盘2或转轴4上设置配重，当结构有限制时，也可以两者都设置配重相配合，可以在转轴4上的飞轮上设置配重。As shown in FIG. 2, the rotating disk 2 is provided with one and the opposite hammer 3 is also provided with only one.
