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.

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.

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.

Preferably, the ultrasonic generator is provided with an intensity switch and a temperature switch, and the opening degrees of the intensity switch and the temperature switch are controlled according to the needs of flotation.

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.

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.

The present invention has achieved the following beneficial technical effects with respect to the prior art:

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.

As shown in FIG. 1 , this embodiment provides a laboratory ultrasonic flotation machine, which includes a base 1, a frame 2, a flotation cell 6 and an ultrasonic generator 7. The frame 2 is arranged on the base 1, and the flotation cell 6 Installed on the frame 2, the ultrasonic waves of the ultrasonic generator 7 are used to act on the flotation cell 6, and a stirring shaft 5 driven by the motor 3 is arranged in the flotation cell 6.

Specifically, the ultrasonic generator 7 is arranged at the bottom of the flotation cell 6 , and the ultrasonic generator 7 is surrounded by the bottom and the periphery of the flotation cell 6 . The ultrasonic generator 7 is provided with an adjustment switch 8. The adjustment switch 8 can be an intensity switch and a temperature switch, and the opening degrees of the intensity switch and the temperature switch are controlled according to the needs of flotation.

Further, a top plate is installed on the top of the frame 2, the motor 3 is installed on the top plate, the transmission shaft of the motor 3 is connected to the top of the stirring shaft 5 through the top plate, and the bottom of the stirring shaft 5 is located in the flotation tank 6.

It also includes a scraper 4 . One end of the scraper 4 is hinged on the frame 2 , and the other end is used for scraping the flotation tank 6 .

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.

An ultrasonic generator 7 or similar components are installed at the bottom of the flotation tank 6. The ultrasonic generator 7 has an adjustment switch 8 so that the ultrasonic generator 7 can be set according to the needs of flotation, thereby improving the dispersion of minerals in the flotation tank 6 and the generation of micro-sized bubbles. Appropriate pulp temperature, etc. An ultrasonic generator 7 is arranged at the bottom of the flotation tank 6. Under the shearing action of ultrasonic waves, micro-sized bubbles will be generated, and the collision probability between the bubbles and the minerals will be increased by using this principle.

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 flotation tank 6 can be achieved by using the vibration and washing action of ultrasonic waves. Ultrasonic intensity can be adjusted according to mineral properties and flotation needs, thereby improving the efficiency of the flotation machine.

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 flotation tank 6, which will greatly reduce the inclusion of the sludge cover and the mechanical inclusion in the flotation process, thereby improving the quality of the flotation foam, and at the same time Under the shearing action of ultrasonic breaking, micro-sized bubbles will be generated in the flotation cell, and the chance of collision between particles and bubbles is greatly increased, so the recovery rate of fine-grained useful minerals can be improved. Under the action of ultrasound, the temperature of the pulp in the flotation tank will increase, which will facilitate the interaction between the flotation reagent and the minerals, and reduce the dosage of the reagent. The invention can transform the on-site flotation machine, which will bring huge economic benefits to enterprises and reduce environmental pollution. Compared with the existing inflatable mechanical stirring flotation machine, it has incomparable advantages. First, the dispersion method is different. Ultrasonic vibration washing is more effective than mechanical stirring and dispersion. Second, the micro-sized bubbles and heating generated by the shearing action of ultrasonic The effect is that the mechanical stirring flotation machine does not have.
