To ensure stable feed and optimum separation.
进一步地，所述多级旋风涡流研磨机整体还包括传动装置，所述传动装置的组成方式为，电动机(2)依次通过动力输出轴、联轴器(3)和主轴传动部件(4)(也称轴承座)将驱动动力传递至多级旋风涡流磨装置。Further, the multi-stage cyclone eddy current grinding machine as a whole further comprises a transmission device, the transmission device is composed of the motor (2) sequentially passing through the power output shaft, the coupling (3) and the spindle transmission component (4) ( Also known as a bearing housing) transmits drive power to a multi-stage cyclone eddy current mill.
进一步地，所述多级旋风涡流研磨机整体还包括多级旋风涡流磨装置，所述多级旋风涡流磨装置由一级转子(9)、二级转子(10)、三级转子(11)和研磨腔构成。所述的一级转子(9)、二级转子(10)、三级转子(11)分别具有直径大小阶梯设计的分三个磨盘，三级转子的间距为1-3mm，优选为2mm。其中，三个磨盘的直径梯度差为100mm，优选地从小到大各级直径的范围依次分别为300-500mm、400-600mm和500-700mm。更加优选地，三个磨盘直径分别为450mm、550mm、650mm。Further, the multi-stage cyclone eddy current grinding machine as a whole further comprises a multi-stage cyclone eddy current grinding device, wherein the multi-stage cyclone eddy current grinding device comprises a first-stage rotor (9), a second-stage rotor (10), and a third-stage rotor (11) It is composed of a grinding chamber. The first-stage rotor (9), the second-stage rotor (10), and the third-stage rotor (11) respectively have three grinding discs with a diameter and a step design, and the third-stage rotor has a spacing of 1-3 mm, preferably 2 mm. Wherein, the diameter difference of the three grinding discs is 100 mm, preferably ranging from small to large, respectively, in the range of 300-500 mm, 400-600 mm and 500-700 mm. More preferably, the three disc diameters are 450 mm, 550 mm, and 650 mm, respectively.
进一步地，所述多级旋风涡流磨装置的核心部分是粉碎装置,该粉碎装置主要包括磨机、磨盘和研磨腔。磨机具有与所述的一级转子(9)、二级转子(10)、三级转子(11)共有呈阶梯设计的三级磨盘，三级磨盘圆周均匀分布的36片转子叶片，一级磨盘、二级磨盘、三级磨盘构成三磨盘的转子叶片数目差为4片。具体地，其中一级磨盘具有16片转子叶片，二级磨盘具有12片转子叶片，三级磨盘具有8片转子叶片。某些情形下，各个磨盘可根据实际需要，增加或减少转子叶片，转子叶片的材质可采用耐磨陶瓷制成。所述各个转子叶片为高速冲击型转子叶片,物料在强离心场中获得很大的动力加速度,在冲击力、碰撞力、剪切力和摩擦力等多种粉碎机理的联合作用下被剥离粉碎。为了提高研磨物料的粉碎效率,在腔体内增加磨壁。磨壁的作用是物料颗粒受到转子叶片的冲击粉碎加速后,在与磨壁的碰撞作用下,使物料再次受到粉碎。针对磨壁结构形式对粉碎效果的显著影响,将磨壁做成耳廓形的特殊齿形。Further, the core portion of the multi-stage cyclone vortex milling device is a pulverizing device, which mainly includes a mill, a grinding disc and a grinding chamber. The mill has a three-stage grinding disc with a stepped design in common with the first-stage rotor (9), the second-stage rotor (10) and the third-stage rotor (11), and 36 rotor blades uniformly distributed on the circumference of the third-stage grinding disc, one stage The number of rotor blades of the three grinding discs consisting of a grinding disc, a secondary grinding disc and a three-stage grinding disc is 4 pieces. Specifically, wherein the primary grinding disc has 16 rotor blades, the secondary grinding disc has 12 rotor blades, and the tertiary grinding disc has 8 rotor blades. In some cases, each disc can be added or reduced according to actual needs, and the rotor blades can be made of wear-resistant ceramic. Each of the rotor blades is a high-speed impact type rotor blade, and the material obtains a large dynamic acceleration in a strong centrifugal field, and is peeled and crushed under the combined action of various crushing mechanisms such as impact force, collision force, shear force and friction force. . In order to increase the pulverization efficiency of the abrasive material, the grinding wall is increased in the cavity. The function of the grinding wall is that after the material particles are accelerated by the impact pulverization of the rotor blades, the material is again pulverized under the collision with the grinding wall. Aiming at the significant influence of the wall structure on the pulverization effect, the grinding wall is made into a special tooth shape of the auricle shape.
具体地，如图2所示，所述的一级转子(9)、二级转子(10)、三级转子(11)对应一级磨盘、二级磨盘、三级磨盘，各级转子(磨盘)组成的有间距的、同轴向的三盘逆向旋转的转盘结构，使得物料经三盘逆向旋转加速后的碰撞速度高达3000转/分钟，其碰撞速度接近气流磨的水平，较大的冲击能量加剧了细胞壁的破碎及机械活化的速度，较高的碰撞速度也增加了植物细胞相互碰撞的几率，更有利于物料的破碎， 使得设备的破碎效能显著地提高。Specifically, as shown in FIG. 2, the first-stage rotor (9), the second-stage rotor (10), and the third-stage rotor (11) correspond to a primary grinding disc, a secondary grinding disc, a third-stage grinding disc, and various stages of rotors (grinding discs). The composition of the three-disc rotating rotating disc structure with the spacing and the axial direction makes the collision speed of the material after the reverse rotation of the three plates up to 3000 rpm, and the collision speed is close to the level of the airflow grinding, and the impact is large. Energy increases the speed of cell wall fragmentation and mechanical activation. The higher collision speed also increases the probability of plant cells colliding with each other, which is more conducive to material fragmentation. This makes the crushing performance of the equipment significantly improved.
进一步具体地，所述的多级旋风涡流磨装置的三级转子结构构成特殊的阶梯研磨腔结构，使得多级旋风涡流磨装置形成分离的、顺序破碎的三个破碎区结构。独特的阶梯研磨腔使得物料在腔内得以较快地提速，进而在相向对撞中产生巨大的破碎能量，并形成设备的第1破碎区；阶梯腔内侧密集锤头的高速冲击，形成设备的第2破碎区和第3破碎区，使得粉体破碎进一步细化。物料经第1破碎区、第2破碎区和第3破碎区的逐腔多段冲击、打击、劈碎相结合，提高了破碎效能。这是其他冲击磨如钉盘磨、横流磨、搅拌磨等所不具备的。这是因为所述的多级旋风涡流磨装置在采用第1破碎区、第2破碎区和第3破碎区合理的破碎顺序后，在转盘的第1破碎区大颗粒物料相互碰撞，碰撞速度能够大于100m/s。粉碎后的物料在负压气流的带动下从转盘的第1破碎区进入第2破碎区和第3破碎区，再对细化后的物料进行冲击。在第2破碎区和第3破碎区的物料受多层冲击元件的逐层剧烈打击，植物的细胞被进一步破碎。这种破碎顺序更有利于延长冲击元件、耐磨件的使用寿命。经过相关权威检验部门的相关数据证明，在同样工艺条件下，该机单位产量的功耗与气流磨、横流磨等相比可以节能50％以上。Further specifically, the three-stage rotor structure of the multi-stage cyclone eddy current grinding device constitutes a special step-grinding cavity structure, so that the multi-stage cyclone eddy current grinding device forms a separate, sequentially broken three crushing zone structure. The unique step grinding chamber enables the material to accelerate faster in the cavity, thereby generating huge crushing energy in the phase collision and forming the first crushing zone of the equipment; the high-speed impact of the dense hammerhead inside the step cavity forms the equipment The second crushing zone and the third crushing zone cause the powder to be broken and further refined. The material is combined with the multi-stage impact, striking and mashing of the first crushing zone, the second crushing zone and the third crushing zone to improve the crushing efficiency. This is not available in other impact mills such as nail disc grinding, cross flow grinding, and agitating grinding. This is because the multi-stage cyclone vortex flow device has a reasonable crushing sequence in the first crushing zone, the second crushing zone and the third crushing zone, and the large particle materials collide with each other in the first crushing zone of the turntable, and the collision speed can be More than 100m/s. The pulverized material enters the second crushing zone and the third crushing zone from the first crushing zone of the turntable under the driving of the negative pressure airflow, and then impacts the refined material. The material in the second crushing zone and the third crushing zone is struck sharply by the layered impact element, and the cells of the plant are further broken. This breaking sequence is more conducive to prolonging the service life of the impact element and the wear part. According to the relevant data of the relevant authoritative inspection department, under the same process conditions, the power consumption per unit of the machine can be more than 50% energy-saving compared with airflow grinding and crossflow grinding.
进一步地，所述的多级旋风涡流磨装置的定子(7)上还具有气流粉碎机，所述气流粉碎机的粉碎室四周一般都设有相向排列的特殊高压进气喷嘴，经过净化和干燥的压缩空气自喷嘴射出，形成超声速气流，物料在高速气流焦点中心发生碰撞，瞬间内被粉碎。经粉碎的粒子随气流上升至分级室，合格的粒子随气流进入旋风分离器，最终获得所需产品，尾气进入除尘器排出。在分级室内设置的涡轮式分级***，可获得数微米甚至更微细的粉体。当粉碎室内被粉碎的物料受上升气流的推动时，在涡轮旋转断面边缘处的同一颗粒将受到离心力场两种不同力的作用(即由涡轮旋转而产生的离心惯性力和气流阻力)。当颗粒较大时，所受离心力大于阻力，大颗粒沿涡轮切线方向飞向分级室器壁，然后返回粉碎室重新被粉碎。当颗粒较小时，此时离心力小于阻力，小颗粒随上升气流进入涡轮内部，经旋风分离器收集为合格产品。本申请中所述的装置正是结合了涡轮粉碎机和气流粉碎机的原理，同时又克服了气流粉碎机存在的不足(完全粉碎)，使设备从立式改为卧式，即可以根据物料各组分特性，在部分粉碎后，形成混合物被高压引风机输送至下一分离环节，在此处，高压引风机不但起到输送的作用，其风量、风压对最终产品的组分及占整个物料的比例，都起着重要 作用。经过大量实验数据证明，风机风量、风压及设备转速三者决定着产品质量，而本申请中的装置能够很好地对所述三者很好地协调。Further, the stator (7) of the multi-stage cyclone vortex milling device further has a jet mill, and the crushing chamber of the jet mill generally has a special high-pressure inlet nozzle arranged to face each other, which is purified and dried. The compressed air is ejected from the nozzle to form a supersonic flow, and the material collides at the center of the high-speed airflow and is pulverized in an instant. The pulverized particles rise to the classification chamber with the gas flow, and the qualified particles enter the cyclone with the gas flow, and finally the desired product is obtained, and the exhaust gas is discharged into the dust remover. A turbo grading system installed in the grading chamber can obtain powders of several micrometers or even finer. When the pulverized material in the pulverizing chamber is pushed by the updraft, the same granule at the edge of the rotating section of the turbine will be subjected to two different forces of the centrifugal force field (i.e., centrifugal inertial force and airflow resistance generated by the rotation of the turbine). When the particles are large, the centrifugal force is greater than the resistance, and the large particles fly toward the wall of the classifying chamber along the tangential direction of the turbine, and then return to the crushing chamber to be pulverized again. When the particles are small, the centrifugal force is less than the resistance at this time, and the small particles enter the inside of the turbine with the rising gas flow, and are collected as qualified products by the cyclone separator. The device described in the present application combines the principles of a turbopulverizer and a jet mill, and at the same time overcomes the shortcomings of the jet mill (complete crushing), so that the device can be changed from vertical to horizontal, that is, according to the material. The characteristics of each component, after partial pulverization, the mixture is transported by the high pressure induced draft fan to the next separation step. Here, the high pressure induced draft fan not only plays the role of transportation, but also the air volume and wind pressure on the components of the final product and The proportion of the entire material plays an important role effect. A large number of experimental data prove that the wind volume, wind pressure and equipment speed determine the product quality, and the device in this application can coordinate well with the three.

Collected by a vacuum suction fan for collection, the cover (8) integral with the discharge port allows the grinding chamber to form a certain volume of space to facilitate the formation of airflow during operation, while also protecting the multi-stage cyclone eddy current mill The device prevents the entry of impurities such as dust.

进一步具体地，所述磨腔内磨壁采用耐磨陶瓷制成，耐磨性好，耐腐蚀，发热量小，且在研磨过程中无金属废料产生，保证物料的食用安全性。Further specifically, the grinding wall in the grinding chamber is made of wear-resistant ceramic, has good wear resistance, corrosion resistance, low heat generation, and no metal scrap is generated during the grinding process to ensure the food safety of the material.
经过多次试验证明，旋风涡流磨电流控制在27A-29A，转速控制在2800转/分钟，能够保证分离效果达到最佳，在磨体冷却装置的配合下，能够散逸磨机的热量，保证连续工作的同时防止物料纤维卷曲、糊化。After many tests, the cyclone eddy current is controlled at 27A-29A, and the rotation speed is controlled at 2800 rpm. This ensures the best separation effect.
