Description

Technical Field

[0001] The utility model relates to the technical field of fluorite flotation, in particular to a precise weighing device for fluorite flotation. Background Technique

[0002] In the prior art, during the processing of fluorite, the flotation method is usually adopted to separate and purify the minerals in the raw materials.

[0003] However, the existing flotation machines need to carry out the diversion of minerals after flotation to realize the independent treatment of different separated substances. However, during the fluorite flotation process, due to the influence of factors such as concentration and temperature, the flotation efficiency is different in each time period, and complete separation cannot be achieved. Therefore, in the actual processing process, it is necessary to select the time period with the highest separation efficiency. After this time period, the efficiency of continuous flotation is difficult to correspond to the cost, so it is necessary to stop or replace the raw materials in time to avoid continuous flotation caused by reduced efficiency and affect the processing cost.

[0004] During the fluorite flotation treatment process, it is necessary to conduct a flotation experiment on the raw materials first, and judge the change of the separation speed during the whole flotation process through the experiment, so as to facilitate the subsequent flotation processing. However, the existing flotation equipment can only realize the recovery of the separated substances, and it is necessary to continuously weigh the recovered substances, so it is difficult to clearly monitor the real-time weight of the separated substances, and it is difficult to timely understand the recovery rate, resulting in an increase in the error of the flotation experiment and the recovery treatment.

[0023] By arranging the weighing sensor 10, the materials recovered in the measuring tool 7 are weighed in real time.

[0024] A rotating frame assembly is arranged outside the tray 9, a display screen 14 with an adjustable angle is rotatably installed on the rotating frame assembly, the display screen 14 is electrically connected to the weighing sensor 10, a positioning column 3 is arranged on the side wall of the flotation machine 1, a telescopic arm assembly is arranged at the lower end of the tray 9, and the end of the telescopic arm assembly is rotatably installed on the positioning column 3.

[0025] By arranging the rotating frame assembly, the angle of the display screen 14 can be adjusted, so as to facilitate timely understanding of the weight of the recovered materials during the flotation process. By using the telescopic arm assembly, the position of the tray 9 can be adjusted, so as to adapt it to the discharge ports on the flotation cells 2 at different positions.

[0026] Working principle: First, place the raw materials in the flotation machine 1, and use the flotation cell 2 for flotation processing and separation, so that the raw materials separated by flotation fall into the measuring tool 7. By arranging the tray 9, the measuring tool 7 is supported, and the telescopic arm assembly is used to adjust the position of the tray 9, so as to adapt to the discharge ports at different positions in the flotation cell 2.

[0027] During the flotation process, by arranging the weighing sensor 10, the materials recovered in the measuring tool 7 are weighed in real time. By arranging the rotating frame assembly, the angle of the display screen 14 can be adjusted, so as to facilitate timely understanding of the weight of the recovered materials during the flotation process. According to the real-time weight change, a change curve of the weight of the recovered materials during the flotation process is generated, so as to obtain a change curve of the flotation efficiency, which is convenient for subsequent parameter adjustment in the fluorite flotation processing process, thereby reducing costs and improving flotation efficiency.
