Description
技术领域：Technical field:
本实用新型属于物料研磨设备领域，特别是涉及一种行星高能球磨机。The utility model belongs to the field of material grinding equipment, in particular to a planetary high-energy ball mill.
背景技术：Background technique:
球磨机作为将固定物料细化制粉的重要设备，广泛应用到冶金、化工、水泥、陶瓷、建筑、电力、医药以及国防工业等部分，对各种矿石和其他可磨性物料进行干式或湿式磨粉。球磨机既可以用于工业化生产中，也可以应用到研发部门或者实验室使用。Ball mill, as an important equipment for finely milling fixed materials, is widely used in metallurgy, chemical industry, cement, ceramics, construction, electric power, medicine and national defense industries, etc., to conduct dry or wet grinding of various ores and other grindable materials. Grinding. Ball mills can be used not only in industrial production, but also in research and development departments or laboratories.
随着现代工业对超细物料需求量的日益增加，对品质要求的不断提高，传统的球磨机在能耗和效率等方面均不能够满足现代化工业以及精细实验的要求。With the increasing demand for ultra-fine materials in modern industry and the continuous improvement of quality requirements, traditional ball mills cannot meet the requirements of modern industry and fine experiments in terms of energy consumption and efficiency.
现有的球磨机在使用时还存在以下几个问题：1、是磨料结底，如果磨料不干燥，在球磨时，由于重力等的作用在极短时间内粉体就会在球磨罐底部大量沉积，而球磨罐内的磨球在离心作用下甩向球磨罐的中部或中上部，致使磨球不能对已沉积在罐底的粉体产生有效作用，纳米组份无法与沉积在底部的粉体接触，从而极大地影响了研磨效果。2、球磨效率低下，球磨时主要研磨面是只有罐壁及罐底，没有充分利用所有面积，降低了球磨效率。3、能耗高，小型球磨机中通常为三个或四个罐体，但是这些罐体只能够同时工作，不能够单独工作，增加了球磨机的能耗。The existing ball mill still has the following problems in use: 1. It is the bottom of the abrasive material. If the abrasive material is not dry, during ball milling, a large amount of powder will be deposited on the bottom of the ball mill tank in a very short time due to the effect of gravity, etc. , and the balls in the ball milling tank are thrown towards the middle or upper middle part of the ball milling tank under centrifugal action, so that the balls cannot effectively act on the powder deposited at the bottom of the tank, and the nano-components cannot be mixed with the powder deposited at the bottom Contact, which greatly affects the grinding effect. 2. The efficiency of ball milling is low. During ball milling, the main grinding surface is only the tank wall and the bottom of the tank. All areas are not fully utilized, which reduces the ball milling efficiency. 3. High energy consumption. There are usually three or four tanks in a small ball mill, but these tanks can only work at the same time, not individually, which increases the energy consumption of the ball mill.

具体实施方式：detailed description:
为使本实用新型的目的、特征和优点能够更为明显易懂，下面结合附图对本实用新型的具体实施方式做详细的说明。In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings.
请参考图1、图2，图1为本实用新型所提供的行星高能球磨机的一种具体实施方式的示意图。Please refer to Fig. 1 and Fig. 2. Fig. 1 is a schematic diagram of a specific embodiment of the planetary high-energy ball mill provided by the present invention.
在这一种具体实施方式中，本实用新型所述的行星高能球磨机，包括机架1，机架1内固定设置有电机2，电机2的主轴上安装有主动皮带轮3，主动皮带轮3通过皮带4连接有从动皮带轮5，从动皮带轮5上方安装有行星齿轮传动机构6，所述行星齿轮传动机构6包括与从动皮带轮5固定连接且随从动皮带轮5转动的太阳齿轮轴61，太阳齿轮轴61上固定连接随太阳齿轮轴61转动的太阳齿轮62，太阳齿轮62的外圈设置有外齿圈63，外齿圈63与机架1固定设置且外齿圈63与太阳齿轮62同心设置，太阳齿轮62与外齿圈63之间设置有多个行星齿轮64，行星齿轮64与太阳齿轮62、外齿圈63均啮合，行星齿轮64的中部均固定设置有行星齿轮轴65，所述行星齿轮轴65上均固定安装有随其转动的球磨罐固定架7，所述球磨罐固定架7内倾斜固定安装有球磨罐8。In this specific embodiment, the planetary high-energy ball mill described in the utility model includes a frame 1, a motor 2 is fixedly arranged in the frame 1, a driving pulley 3 is installed on the main shaft of the motor 2, and the driving pulley 3 passes through the belt 4 is connected with a driven pulley 5, and a planetary gear transmission mechanism 6 is installed above the driven pulley 5, and the planetary gear transmission mechanism 6 includes a sun gear shaft 61 that is fixedly connected with the driven pulley 5 and rotates with the driven pulley 5, and the sun gear The shaft 61 is fixedly connected with the sun gear 62 that rotates with the sun gear shaft 61. The outer ring of the sun gear 62 is provided with an outer ring gear 63. A plurality of planetary gears 64 are arranged between the sun gear 62 and the outer ring gear 63, and the planetary gears 64 mesh with the sun gear 62 and the outer ring gear 63, and the planetary gear shafts 65 are fixedly arranged in the middle of the planetary gears 64. The planetary gear shafts 65 are all fixedly installed with a ball milling pot holder 7 that rotates with it, and the ball milling pot holder 7 is obliquely fixedly equipped with a ball milling pot 8 .
本实用新型的工作过程为：电机2带动主动皮带轮3转动，主动皮带轮3通过皮带4带动从动皮带轮5转动，太阳齿轮轴61随从动皮带轮5转动，太阳齿轮轴61转动的过程带动与其键连接的太阳齿轮62转动，太阳齿轮62转动从而带动与其啮合行星齿轮64转动，行星齿轮64既绕太阳齿轮62公转同时也绕行星齿轮轴65自转，球磨罐固定架7跟随行星齿轮64运动。球磨罐8与水平面呈一定角度倾斜设置，这样球磨罐8在转动过程中没有固定底面，能够有效解决粉体结底的问题。另外，倾斜设置的球磨罐8能够使磨球的运动轨迹复杂化，增加球磨效率。The working process of the utility model is: the motor 2 drives the driving pulley 3 to rotate, the driving pulley 3 drives the driven pulley 5 to rotate through the belt 4, the sun gear shaft 61 rotates with the driven pulley 5, and the process of the sun gear shaft 61 rotating drives its key connection The sun gear 62 rotates, and the sun gear 62 rotates to drive the planetary gear 64 meshed with it to rotate. The planetary gear 64 both revolves around the sun gear 62 and also rotates around the planetary gear shaft 65. The ball milling pot holder 7 follows the planetary gear 64 motion. The ball milling pot 8 is inclined at a certain angle to the horizontal plane, so that the ball milling pot 8 does not have a fixed bottom surface during rotation, which can effectively solve the problem of powder bottoming. In addition, the inclined ball milling pot 8 can complicate the movement track of the balls and increase the ball milling efficiency.
需要说明的是，本实施例中采用的是行星齿轮64传动系统来实现电机2带动球磨罐8的运动。当然也可以采用其他行星传动机构来实现此功能，比如皮带4行星传动机构。另外，球磨罐8的数量可以根据球磨机的使用环境进行选择，可以为两个，也可以为三个，或四个。然后根据球磨罐8的数量选择相同数量的行星齿轮64。It should be noted that, in this embodiment, the planetary gear 64 transmission system is used to realize the movement of the ball mill jar 8 driven by the motor 2 . Certainly also can adopt other planetary transmission mechanism to realize this function, such as belt 4 planetary transmission mechanism. In addition, the number of ball mill tanks 8 can be selected according to the use environment of the ball mill, and can be two, three, or four. Then select the same number of planetary gears 64 according to the number of ball mill jars 8 .
请参图4，在上述实施例的基础上，在本实用新型的另一种具体实施方式中，具体描述一种球磨罐固定架7的具体结构：包括与行星齿轮轴65固定连接的底座71，底座71的上表面为倾斜面72，底座71上方设置有用于放置球磨罐8的固定架筒体73，固定架筒体73的顶部设置有球磨罐压紧盖74，球磨罐压紧盖74的上方设置有压紧螺杆螺母75，压紧螺杆螺母75的上方固定设置有转动把手76。Please refer to Fig. 4, on the basis of the above-mentioned embodiment, in another specific embodiment of the present utility model, a specific structure of a ball milling pot fixing frame 7 is described in detail: it includes a base 71 fixedly connected to the planetary gear shaft 65 , the upper surface of the base 71 is an inclined surface 72, the top of the base 71 is provided with a fixed frame cylinder 73 for placing the ball milling tank 8, the top of the fixed frame cylinder 73 is provided with a ball milling tank compression cover 74, and the ball milling tank compression cover 74 A compression screw nut 75 is arranged above the top of the compression screw nut 75, and a rotating handle 76 is fixedly arranged above the compression screw nut 75.
采用这种结构的球磨罐固定架7，可以不改变传统球磨罐8的结构，能够与现有球磨罐8通用。只需要将球磨罐8安装到球磨罐固定架7上就能够实现球磨罐8的倾斜安装。球磨罐8安装到球磨罐固定架7后，转动把手76利用压紧螺杆螺母75和球磨罐压紧盖74将球磨罐8固定。球磨罐8固定后，在转动时，除了跟随行星齿轮64产生的公转和自转，增加了球磨罐8绕中心轴的圆锥形摆动，使球磨罐8内磨球的运动轨迹更加复杂、无规律，增加磨球与磨料、球磨罐8的内壁碰撞的机率，大大改善球磨效率。The ball milling pot fixing frame 7 adopting this structure can be used in common with the existing ball milling pot 8 without changing the structure of the traditional ball milling pot 8 . The oblique installation of the ball milling pot 8 can be realized only by installing the ball milling pot 8 on the ball milling pot fixing frame 7 . After ball milling pot 8 is installed in ball milling pot holder 7, turning handle 76 utilizes compression screw nut 75 and ball milling pot compression cover 74 to fix ball milling pot 8. After the ball mill pot 8 is fixed, when rotating, in addition to following the revolution and rotation generated by the planetary gear 64, the conical swing of the ball mill pot 8 around the central axis is increased, making the trajectory of the balls in the ball mill pot 8 more complicated and irregular. The probability of collision between the grinding ball and the abrasive material and the inner wall of the ball milling tank 8 is increased, and the ball milling efficiency is greatly improved.
为了同时满足磨球运动轨迹复杂化和球磨机运动稳定性的要求，将倾斜面72与水平面的夹角限制在5-10度。倾斜角度增大后，会增加整个行星高能球磨机的体积，而且会降低整个球磨机运动的稳定性。倾斜角度太小不对于磨球运动轨迹的变化贡献不大，而且还会存在粉体结底的问题。In order to simultaneously meet the requirements of the complicated motion trajectory of the ball mill and the motion stability of the ball mill, the included angle between the inclined surface 72 and the horizontal plane is limited to 5-10 degrees. When the inclination angle increases, the volume of the entire planetary high-energy ball mill will be increased, and the stability of the entire ball mill movement will be reduced. If the inclination angle is too small, it will not contribute much to the change of the trajectory of the ball, and there will be a problem of powder bottoming.
为了从根本上解决球磨罐8内粉体结底的问题，在上述实施例的基础上，在本实用新型的另一种具体实施方式中，采用下面球磨罐8的结构：包括罐体81，罐体81的顶部安装有用于密封的罐盖82，罐体81的底部固定设置有搅拌电机83，搅拌电机83的输出轴上连接有搅拌轴84，搅拌轴84穿过罐体81底部延伸到罐体81内部，延伸到罐体81内部的搅拌轴84上安装有多个搅拌叶片85，所述搅拌叶片85上方安装有防护罩86。In order to fundamentally solve the problem of powder bottoming in the ball milling tank 8, on the basis of the above-mentioned embodiments, in another specific embodiment of the present utility model, the following structure of the ball milling tank 8 is adopted: comprising a tank body 81, The top of the tank body 81 is equipped with a tank cover 82 for sealing, the bottom of the tank body 81 is fixedly provided with a stirring motor 83, the output shaft of the stirring motor 83 is connected with a stirring shaft 84, and the stirring shaft 84 extends through the bottom of the tank body 81 to Inside the tank body 81 , a plurality of stirring blades 85 are installed on the stirring shaft 84 extending to the inside of the tank body 81 , and a protective cover 86 is installed above the stirring blades 85 .
工作时，球磨罐8除了上述两个实施例中描述的运动以外，在搅拌电机83的作用下，带动搅拌轴84和搅拌叶片85运动，从根本上解决了采用常规球磨罐8制备粉体时，由于重力等作用引起的粉体在罐底沉积问题。另外，搅拌叶片85增加了磨球介质在球磨罐8中的运动速度，同时使其运动轨迹更加复杂化和无规律化，极大地提升球磨效率，减少制作成粉体的时间，提升了粉体品质。During work, in addition to the movement described in the above two embodiments, the ball milling pot 8 drives the stirring shaft 84 and the stirring blade 85 to move under the action of the stirring motor 83, which fundamentally solves the problem of using the conventional ball milling pot 8 to prepare powder. , The problem of powder deposition at the bottom of the tank due to gravity and other effects. In addition, the stirring blade 85 increases the movement speed of the grinding ball medium in the ball milling tank 8, and at the same time makes its trajectory more complicated and irregular, which greatly improves the ball milling efficiency, reduces the time for making powder, and improves the quality of the powder. quality.
为了增加搅拌轴84与罐体81处的密封性能，所述搅拌轴84与罐体81的连接处设置有密封套和密封圈。另外，在所述防护罩86的四周和顶部包裹有镂空的铁丝网。防止罐中的磨球对搅拌叶片85造成损伤。In order to increase the sealing performance between the stirring shaft 84 and the tank body 81 , a sealing sleeve and a sealing ring are provided at the connection between the stirring shaft 84 and the tank body 81 . In addition, hollow barbed wire is wrapped around and on the top of the protective cover 86 . Prevent the grinding balls in the tank from causing damage to the stirring blade 85.
如图3所示，在上述实施例的基础上，在本实用新型的另一种具体实施方式中，所述行星齿轮64与行星齿轮轴65之间通过电磁离合器9连接。传统的行星高能球磨机的多个球磨罐8均是同时工作，但是在实验室时或者企业研发部应用的小型球磨机在做实验使用时，通常不需要多个球磨罐8使用。通过在行星齿轮64和行星齿轮轴65之间增加电磁离合器9，利用电磁离合器9断开行星齿轮64与行星齿轮轴65，这时球磨罐8只有公转没有自转，降低电机2能耗。As shown in FIG. 3 , on the basis of the above embodiments, in another embodiment of the present utility model, the planetary gear 64 is connected to the planetary gear shaft 65 through an electromagnetic clutch 9 . Multiple ball milling tanks 8 of a traditional planetary high-energy ball mill work at the same time, but when using a small ball mill in a laboratory or in an enterprise R&D department for experiments, multiple ball milling tanks 8 are usually not needed. By increasing the electromagnetic clutch 9 between the planetary gear 64 and the planetary gear shaft 65, utilizing the electromagnetic clutch 9 to disconnect the planetary gear 64 and the planetary gear shaft 65, at this moment, the ball mill jar 8 only revolves without rotation, reducing the energy consumption of the motor 2.
而且为了提升增加行星球磨机的自动化程度，可以增加控制单元，控制单元通过变频器与电机2连接，电磁离合器9以及搅拌电机83也均与控制单元电连接由控制单元控制运动。And in order to increase the degree of automation of the planetary ball mill, a control unit can be added, the control unit is connected to the motor 2 through a frequency converter, the electromagnetic clutch 9 and the stirring motor 83 are also electrically connected to the control unit, and the control unit controls the movement.
综上所述，本实用新型提供的行星高能球磨机能够从根本上解决球磨罐8结底的问题，而且通过增肌磨球的运动速率，使磨球的运动轨迹复杂化、无序化，从而降低球磨机能耗、提升球磨机效率。In summary, the planetary high-energy ball mill provided by the utility model can fundamentally solve the problem of the bottom of the ball mill tank 8, and by increasing the movement speed of the balls, the trajectory of the balls is complicated and disordered, thereby Reduce the energy consumption of the ball mill and improve the efficiency of the ball mill.
上面结合附图对本实用新型的实施例作了详细说明，但是本实用新型并不限于上述实施例，在本领域普通技术人员所具备的知识范围内，还可以在不脱离本实用新型宗旨的前提下作出各种变化。The above embodiments of the utility model have been described in detail in conjunction with the accompanying drawings, but the utility model is not limited to the above-mentioned embodiments.
