技术领域technical field
本发明涉及选矿设备技术领域，特别是涉及一种实验室超声浮选机。The invention relates to the technical field of mineral processing equipment, in particular to a laboratory ultrasonic flotation machine.
背景技术Background technique
浮选是当前有效且常用的选矿方法，尤其是难选矿石，要想矿物颗粒实现有效的浮选，首先矿物颗粒必须要得到有效分散，因此提高浮选机性能成为关键。针对我国矿物资源贫、细、杂等特点，开发适应当前矿物特性的高效实验室浮选机成为研发重点，进而实现工业化。Flotation is an effective and commonly used mineral processing method, especially for refractory ores. In order to achieve effective flotation of mineral particles, the mineral particles must be effectively dispersed first, so improving the performance of the flotation machine becomes the key. In view of the characteristics of poor, fine and miscellaneous mineral resources in my country, the development of high-efficiency laboratory flotation machines adapted to the current mineral characteristics has become the focus of research and development, and then realizes industrialization.
目前实验室采用的浮选机多半是自吸气机械搅拌式浮选机，浮选槽体中搅拌不均匀，因而细颗粒矿物团聚严重，不能充分使矿物颗粒有效分散，进而影响选别指标；还有一部分为充气式机械搅拌浮选机，但是充气式机械搅拌浮选机产生气泡尺寸大小不一。鉴于实验室浮选机有上述缺点，发明了一种新型实验室超声浮选机。At present, most of the flotation machines used in the laboratory are self-aspirating mechanical stirring flotation machines, and the stirring in the flotation tank body is uneven, so the fine-grained minerals are seriously agglomerated, and the mineral particles cannot be fully dispersed effectively, thereby affecting the sorting index; There is also a part of the inflatable mechanical stirring flotation machine, but the size of the bubbles produced by the inflatable mechanical stirring flotation machine is different. In view of the above shortcomings of the laboratory flotation machine, a new type of laboratory ultrasonic flotation machine was invented.
发明内容SUMMARY OF THE INVENTION
本发明的目的是提供一种实验室超声浮选机，以解决上述现有技术存在的问题，有利于细粒矿物在浮选机中分散，进而减少矿物颗粒浮选的机械夹杂，提高精矿品位。The purpose of the present invention is to provide a laboratory ultrasonic flotation machine, so as to solve the problems existing in the above-mentioned prior art, which is conducive to the dispersion of fine-grained minerals in the flotation machine, thereby reducing the mechanical inclusion of mineral particles in flotation, and improving the concentration of concentrates. grade.
为实现上述目的，本发明提供了如下方案：本发明提供一种实验室超声浮选机，包括底座、机架、浮选槽和超声波发生器，所述机架设置于所述底座上，所述浮选槽安装在所述机架上，所述超声波发生器的超声波用于作用到所述浮选槽上，所述浮选槽内设置有电机驱动的搅拌轴。In order to achieve the above purpose, the present invention provides the following solutions: the present invention provides a laboratory ultrasonic flotation machine, comprising a base, a frame, a flotation cell and an ultrasonic generator, the frame is arranged on the base, and the The flotation cell is installed on the frame, the ultrasonic waves of the ultrasonic generator are used to act on the flotation cell, and a motor-driven stirring shaft is arranged in the flotation cell.
优选地，所述超声波发生器设置在所述浮选槽的底部，且所述超声波发生器包围在所述浮选槽的底部和四周。Preferably, the ultrasonic generator is arranged at the bottom of the flotation cell, and the ultrasonic generator is surrounded by the bottom and the periphery of the flotation cell.

优选地，所述机架的顶部安装有顶板，所述电机安装在所述顶板上，所述电机的传动轴穿过所述顶板与所述搅拌轴的顶部传动连接，所述搅拌轴的底部位于所述浮选槽内。Preferably, a top plate is installed on the top of the frame, the motor is installed on the top plate, the drive shaft of the motor passes through the top plate and is connected to the top of the stirring shaft in a driving manner, and the bottom of the stirring shaft is connected to the top of the stirring shaft. in the flotation cell.
优选地，还包括有刮板，所述刮板的一端铰接在所述机架上，另一端用于对所述浮选槽内进行刮料。Preferably, it also includes a scraper, one end of the scraper is hinged on the frame, and the other end is used for scraping the flotation tank.
本发明相对于现有技术取得了以下有益技术效果：The present invention has achieved the following beneficial technical effects with respect to the prior art:
本发明的实验室超声浮选机，可以根据需要调整超声波强度，随着原矿结晶粒度越来越细，矿物颗粒的分散也需要改进，本发明的浮选机可以使矿物颗粒分散更好，且有利于破除细颗粒矿泥对矿物的罩盖，由于超声作用使浮选槽底部产生微尺寸气泡，从整个槽体底部发生并向上运动，可以更有效的增加细粒级矿物与气泡的碰撞几率。颗粒的分散效果是充气机械搅拌式浮选机大无法比拟的，故微泡浮选机可以提高微细粒有用矿物回收率及品位，同时减少浮选药剂用量。现有浮选机的搅拌方式为搅拌轴机械式搅拌，受搅拌强度和浮选槽空间等限制，很难达到矿物颗粒的充分分散，尤其是细颗粒矿泥罩盖在粗颗粒上的颗粒之间分散基本不能实现。从而影响矿粒的分选与回收，造成资源浪费。本发明的实验室超声浮选机解决了充气式机械搅拌浮选机的矿物颗粒分散缺陷，能够使颗粒更好的分散，尤其是矿泥罩盖现象。且伴随分散还产生微尺寸气泡，更加有利于浮选进行，提高浮选机的功效。The laboratory ultrasonic flotation machine of the present invention can adjust the ultrasonic intensity according to the needs. As the crystal size of the raw ore becomes finer and finer, the dispersion of the mineral particles also needs to be improved. The flotation machine of the present invention can make the mineral particles disperse better, and It is beneficial to break the cover of the fine-grained sludge on the minerals. Due to the ultrasonic action, micro-sized bubbles are generated at the bottom of the flotation tank, which occur from the bottom of the entire tank and move upwards, which can more effectively increase the collision probability between fine-grained minerals and bubbles. . The dispersion effect of particles is incomparable with the inflatable mechanical stirring flotation machine, so the microbubble flotation machine can improve the recovery rate and grade of useful minerals of fine particles, and reduce the dosage of flotation reagents. The stirring method of the existing flotation machine is the mechanical stirring of the stirring shaft, which is limited by the stirring strength and the space of the flotation tank, and it is difficult to achieve the full dispersion of the mineral particles, especially the fine-grained sludge is covered on the coarse particles. Inter-distribution is basically impossible to achieve. This affects the sorting and recycling of ore particles, resulting in waste of resources. The laboratory ultrasonic flotation machine of the invention solves the mineral particle dispersion defect of the inflatable mechanical stirring flotation machine, and can better disperse the particles, especially the phenomenon of mud capping. And with the dispersion, micro-sized bubbles are also generated, which is more conducive to the flotation and improves the efficiency of the flotation machine.

如图1所示，本实施例提供一种实验室超声浮选机，包括底座1、机架2、浮选槽6和超声波发生器7，机架2设置于底座1上，浮选槽6安装在机架2上，超声波发生器7的超声波用于作用到浮选槽6上，浮选槽6内设置有电机3驱动的搅拌轴5。As shown in FIG. 1 , this embodiment provides a laboratory ultrasonic flotation machine, which includes a
具体地，超声波发生器7设置在浮选槽6的底部，且超声波发生器7包围在浮选槽6的底部和四周。超声波发生器7上设置有调节开关8，调节开关8可以是强度开关和温度开关，根据浮选需要控制强度开关和温度开关的开度。Specifically, the ultrasonic generator 7 is arranged at the bottom of the
进一步地，机架2的顶部安装有顶板，电机3安装在顶板上，电机3的传动轴穿过顶板与搅拌轴5的顶部传动连接，搅拌轴5的底部位于浮选槽6内。Further, a top plate is installed on the top of the
还包括有刮板4，刮板4的一端铰接在机架2上，另一端用于对浮选槽6内进行刮料。It also includes a
本发明中的实验室超声浮选机在浮选机上引入超声波，一方面超声会产生微尺寸气泡，更加有利于微细粒矿物浮选，同时减少药剂用量。另一方面在超声作用下矿浆会被加热，从而增强药剂与矿物作用效果。上述优势都将增强浮选效果，比充气机械搅拌式浮选机精矿品位提高1.5％且回收率提高1％以上。In the laboratory ultrasonic flotation machine in the present invention, ultrasonic waves are introduced into the flotation machine. On the one hand, ultrasonic waves will generate micro-sized bubbles, which is more conducive to the flotation of fine-grained minerals, and at the same time reduces the dosage of chemicals. On the other hand, under the action of ultrasound, the pulp will be heated, thereby enhancing the effect of the chemical and minerals. The above advantages will enhance the flotation effect, and the concentrate grade will be increased by 1.5% and the recovery rate will be increased by more than 1% compared with the pneumatic mechanical stirring flotation machine.
浮选槽6底部加装超声发生器7或类似部件，超声发生器7有调节开关8以便根据浮选需要设置超声发生器7，进而提高浮选槽6中矿物的分散及产生微尺寸气泡与合适的矿浆温度等。在浮选槽6底部设置超声发生器7，在超声波的剪切作用下，会产生微尺寸气泡，利用这种原理增加气泡与矿物碰撞几率。An ultrasonic generator 7 or similar components are installed at the bottom of the
随着原矿结晶粒度越来越细，如何使矿物颗粒有效分散是浮选的关键。由于本发明在槽体底部超声发生器7，利用超声波的震荡洗涤作用可以实现浮选槽6中矿物颗粒的更佳有效分散。超声强度可以根据矿物特性及浮选需要调节，进而提高浮选机效率。As the crystal size of raw ore becomes finer and finer, how to effectively disperse the mineral particles is the key to flotation. Because of the ultrasonic generator 7 at the bottom of the tank in the present invention, better and effective dispersion of the mineral particles in the
本发明的浮选机利用机械搅拌与超声波震荡洗涤协同作用对浮选槽6中矿物颗粒进行分散，将大大降低浮选工程中矿泥罩盖与机械夹杂，从而提高浮选泡沫的品位，同时在超声破的剪切作用下，浮选槽中会产生微尺寸气泡，颗粒与气泡碰撞机会大大增加，因此可以提高微细粒有用矿物回收率。在超声作用下，浮选槽中矿浆温度会增加，这将有利于浮选药剂与矿物作用，且减少药剂用量。此发明可以对现场浮选机进行改造，将为企业带来巨大经济效益且减少环境污染。与现有充气机械搅拌式浮选机相比，有着无可比拟的优点，首先分散方式不同，超声波震荡洗涤要比机械搅拌分散的更加有效，其次超声的剪切作用产生的微尺寸气泡和加热功效是机械搅拌式浮选机所不具备的。The flotation machine of the present invention utilizes the synergistic effect of mechanical stirring and ultrasonic vibration washing to disperse the mineral particles in the
