Description

Technical Field

[0001] This utility model belongs to the field of chemical process machinery technology, and in particular relates to a multi-functional flotation machine. Background Technology

[0002] With the increasing demand for metals at present, the resources of coarse lead, zinc and copper sulfide ores that can be processed by gravity separation are decreasing. Flotation has been proposed as a method for separating fine-grained ores. Flotation is applied in the pharmaceutical and metallurgical industries, such as using the natural hydrophobicity of mineral surfaces to purify mineral medicines such as cinnabar and talc, and using goose feathers dipped in oil to scrape gold powder floating on the water surface during gold and silver washing, so as to separate it from hydrophilic impurities.

[0003] The agitator motor in the flotation machine operates at a fixed speed, and the aeration volume only has two states: on and off. This cannot effectively cope with the complex changes during flotation, affecting the recovery rate. In addition, the scraper motor in the froth separator operates at a fixed speed, and cannot be adjusted according to changes in froth thickness and concentrate grade at different stages of closed-circuit flotation, making it difficult to balance flotation speed and concentrate grade. Summary of the Invention

[0004] In response to the above situation, in order to overcome the shortcomings of existing technologies that cannot adjust the flotation process.

[0005] The technical solution adopted by this utility model is as follows: a multi-functional flotation machine includes a tank and a partition. The partition is fixed to the inside of the tank and divides the tank into a flotation chamber and a collection chamber. A stirring assembly is provided at the bottom of the flotation chamber. The stirring assembly is used to realize mineral beneficiation operation. A toggle assembly is provided between the upper ends of the partition.

[0006] Furthermore, the stirring assembly includes an annular shell, a baffle, a bubble generator 1, and a bubble generator 2. The annular shell is fixed to the bottom end of the flotation chamber. A closed pressurization chamber is formed inside the annular shell. A plurality of liquid outlets are spaced apart on the inner side of the pressurization chamber. One end of the pressurization chamber is connected to the liquid outlet of a pressure pump through a conduit. The pressure pump is fixed to the bottom end of the flotation chamber. The baffle is fixed to the upper end of the annular shell. A closed gas storage chamber 1 and a gas storage chamber 2 are formed inside the baffle. A plurality of bubble generators 1 are spaced apart and fixed to the inner side of the baffle along the central axis. A plurality of bubble generators 2 are spaced apart and fixed to the inner side of the baffle along the central axis. The gas storage chambers 1 and 2 are respectively connected to the gas outlet of an air pump through conduits. The air pump is located outside the tank. A solenoid valve is provided between the air pump and the conduit. A plurality of through holes are spaced apart on the lower end of the annular shell.

[0007] Furthermore, the actuation assembly includes a power rod, brackets, and actuation plates. The power rod is rotatably mounted on both sides of the cabinet at the upper end of the partition. Several brackets are fixedly connected to the outside of the power rod at intervals along the central axis of the power rod. The actuation plates are fixedly connected to the brackets through a rotating shaft. The extended end of the power rod is poweredly connected to the power shaft of a rotary motor.

[0008] Furthermore, a microprocessor is provided on the outside of the tank. The microprocessor is electrically connected to the display via wires. The air pump is electrically connected to the microprocessor via wires. The pressurizing pump is electrically connected to the microprocessor via wires. The solenoid valve is electrically connected to the microprocessor via wires. The rotary motor is electrically connected to the microprocessor via wires.

[0009] Furthermore, the aperture of bubble generator one is larger than that of bubble generator two, and bubble generator one and bubble generator two respectively connect gas storage chamber one and gas storage chamber two to flotation chamber.

[0010] Furthermore, the actuating plate is arc-shaped and is matched with the upper end of the partition.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows:

[0012] (1) Based on the complex situation during flotation, the solenoid valve controlled by the microprocessor is used to change the air passage of gas storage chamber one and gas storage chamber two, thereby carrying coarse minerals and capturing fine minerals. The linkage between the booster chamber and the booster pump is used to enhance the mixing of bubbles in the liquid and improve the mineralization efficiency.

[0013] (2) Adjust the angle of the arc-shaped actuating plate between the supports according to the changes in foam thickness and concentrate grade, thereby changing the actuating depth of the actuating plate, ensuring flotation speed while improving concentrate grade. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0023] like Figure 1-2 As shown, a multi-functional flotation machine includes a tank 1 and a partition 2. The partition 2 is fixed to the inside of the tank 1 and divides the tank 1 into a flotation chamber 3 and a collection chamber 4. A stirring assembly is provided at the bottom of the flotation chamber 3. The stirring assembly is used to realize mineral beneficiation operation. A toggle assembly is provided at the upper end of the partition 2.

[0024] like Figure 3-5As shown, the stirring assembly includes an annular shell 5, a baffle 6, a bubble generator 1 7, and a bubble generator 2 8. The annular shell 5 is fixed to the bottom of the flotation chamber 3. A closed pressurization chamber 9 is provided inside the annular shell 5. Several liquid outlets 10 are provided at intervals on the inner side of the pressurization chamber 9. One end of the pressurization chamber 9 is connected to the liquid outlet of the pressurization pump 14 through a conduit. The pressurization pump 14 is fixed to the bottom of the flotation chamber 3. The baffle 6 is fixed to the upper end of the annular shell 5. A closed gas storage chamber 1 11 and a gas storage chamber 2 12 are provided inside the baffle 6. Several bubble generators 1 7 are fixed at intervals on the inner side of the baffle 6 along the central axis of the baffle 6. Several bubble generators 2 8 are fixed at intervals on the inner side of the baffle 6 along the central axis of the baffle 6. The gas storage chambers 1 11 and 2 12 are respectively connected to the gas outlet of the air pump through conduits. The air pump is located outside the tank 1. A solenoid valve is provided between the air pump and the conduit. Several through holes 13 are provided at intervals on the lower end of the annular shell 5.

[0025] Among them, the aperture of bubble generator 7 is larger than that of bubble generator 8. Bubble generator 7 and bubble generator 8 connect gas storage chamber 11 and gas storage chamber 22 to flotation chamber 3, respectively. The microprocessor controls the solenoid valve to enter the bubble generator 7, which is arranged in a ring inside the gas storage chamber 11, to generate large bubbles that carry coarse minerals. The microprocessor controls the solenoid valve to enter the bubble generator 8, which is arranged in a ring inside the gas storage chamber 22, to generate microbubbles, such as microbubbles generated by porous ceramics to capture fine minerals. The microprocessor controls the pressurization pump 14 to draw the liquid in flotation chamber 3 into the pressurization chamber for pressurization, and then spray the pressurized liquid out through the spaced liquid outlets 10. The flow velocity at the upper end of the enclosure 6 increases and the pressure decreases, so that the liquid in flotation chamber 3 is forced into the enclosure of the enclosure 6 through the through hole 13 for sequential circulation. During the circulation process, the bubbles generated by bubble generator 7 and bubble generator 8 mix with the circulating liquid flow, increasing the uniform mixing of airflow and liquid and improving mineralization efficiency.

[0026] like Figure 2-4 As shown, the actuation assembly includes a power rod 15, a bracket 16, and an actuation plate 17. The power rod 15 is rotatably mounted on both sides of the cabinet at the upper end of the partition 2. Several brackets 16 are fixedly connected to the outside of the power rod 15 at intervals along the central axis of the power rod 15. The actuation plate 17 is fixedly connected to the brackets 16 through a rotating shaft. The extended end of the power rod 15 is poweredly connected to the power shaft of the rotary motor 18.

[0027] The tank 1 is equipped with a microprocessor on its outer side. The microprocessor is electrically connected to the display via wires. The air pump, the pressurizing pump 14, the solenoid valve, and the rotary motor 18 are all electrically connected to the microprocessor via wires. The actuating plate 17 is arc-shaped and is matched with the upper end of the partition 2. The microprocessor controls the rotary motor 18 to drive the actuating plate 17 on the power rod 15 to scrape the bubble layer on the surface of the liquid during flotation. The angle of the arc-shaped actuating plate 17 between the supports 16 is adjusted according to the changes in foam thickness and concentrate grade, thereby changing the adjustment of the actuating depth of the actuating plate 17, ensuring the flotation speed while improving the concentrate grade.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
