Description

Technical Field

[0001] The utility model relates to the technical field of flotation machine devices, in particular to an automatic grading flotation machine. Background Art

[0002] Minerals are natural compounds with a certain chemical composition in nature, with stable phase interfaces and crystallization habits. These minerals are formed by geological actions, including volcanic action, magmatic action, weathering, sedimentation, etc. Usually, multiple steps are used to process minerals, such as flotation. Through multiple steps, the target metal or non-metal can be separated from the ore, and the desired final product can be obtained through refining and processing. Mineral processing involves knowledge and technology in multiple fields, which is of great significance for improving the utilization rate of mineral resources and protecting the environment.

[0003] Among them, flotation is an important ore beneficiation technology, which is mainly used to separate useful minerals from useless minerals in ores. Its basic principle is to utilize the differences in the physical and chemical properties of the mineral surface. By adding flotation agents and introducing air into the slurry to form bubbles, useful mineral particles are attached to the bubbles and float out, while useless minerals sink to the bottom, thereby realizing the separation of useful minerals from gangue. In short, flotation is an important ore beneficiation technology with broad application prospects and important economic value.

[0004] At present, when using a flotation machine to separate useful minerals from non-useful minerals in an ore, it is usually necessary to open the water valve so that the water level inside the device is within an appropriate range, and then the slurry is evenly fed into the device. At the same time, air needs to be fed into the device to maintain appropriate air pressure and bubble size. Finally, the stirring device can be turned on to inject air or other gases into the slurry to generate a large number of fine bubbles, which is convenient for better separation of useful minerals and non-useful minerals in the ore.

[0005] However, when the flotation machine is used, since the bubble removal device installed in the existing flotation machine is fixedly connected to both sides of the flotation machine, its position is fixed. Therefore, when the device is used, the water level inside and the amount of slurry added are both quantitative, thereby reducing the flexibility of the device and reducing the utilization efficiency of the device. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide an automatic grading flotation machine to solve the technical problem that the bubble removal device is fixedly connected to both sides of the flotation machine when installed in the existing flotation machine, so that its position is fixed. Therefore, when the device is used, the water level inside and the amount of ore pulp added are both quantitative, thereby reducing the flexibility of the device and reducing the utilization efficiency of the device.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic grading flotation machine, comprising a box body, the four bottom corners of the box body are fixedly connected with supporting legs, grooves are arranged at both ends of the box body, protrusions are slidably connected at both ends of the box body, and the protrusions are matched with the grooves, a floating plate is fixedly connected to the top of the protrusion, a group of limit grooves are arranged on both sides of the box body, and limit blocks matching with the limit grooves are slidably connected in the limit grooves, the limit blocks are fixedly connected to the corresponding two sides of the floating plate, and the limit blocks are arranged as a "T"-shaped structure, and a stirring device is arranged in the box body.
