Description

Technical Field

[0001] This utility model relates to the field of flotation machine technology, and in particular to an automatic dosing device for flotation machines. Background Technology

[0002] Flotation is a commonly used ore beneficiation method that separates valuable minerals from waste rock by utilizing the differences in their physical and chemical properties. In flotation, the ore is first crushed and ground, then certain reagents are added to create differences in hydrophilicity and hydrophobicity between the valuable minerals and the waste rock. The valuable minerals are then floated to the surface in a stirred tank by air bubbles, forming scum, while the waste rock settles to the bottom, thus achieving the separation and purification of the valuable minerals.

[0003] In existing technologies, flotation machines require reagent addition within the flotation cells during operation. However, the lack of automated reagent addition mechanisms means that the reagent dosage cannot be precisely controlled, relying on manual operation and prone to fluctuations and instability. This can lead to uneven reagent concentration, affecting flotation efficiency and ore recovery. Furthermore, the inability to automate the reagent addition process hinders seamless integration with other automated equipment, reducing the overall automation level of the flotation process.

[0025] Example 1

[0026] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic dosing device for a flotation machine, comprising: a dosing mechanism 1, a buffer mechanism 2 at the bottom of the dosing mechanism 1, the dosing mechanism 1 including a flotation cell 11, a rotating roller 12 disposed inside the flotation cell 11, the interior of the flotation cell 11 being rotatably connected to one end of the rotating roller 12, the other end of the rotating roller 12 being movably connected through the interior of the flotation cell 11, a gear 13 disposed at one end of the rotating roller 12, one end of the rotating roller 12 being fixedly connected to one side of the gear 13, a tooth 14 disposed on the outer side of the gear 13, the outer side of the gear 13 being meshed with the interior of the tooth 14, and an electric... The other side of the gear 13 is fixedly connected to the output end of the motor 15. The bottom side of the motor 15 is fixedly connected to one side of the flotation cell 11. The interior of the flotation cell 11 is fixedly connected to one end of the pump body 16. The other end of the pump body 16 is provided with a connecting pipe 17, which is fixedly connected to the interior of the connecting pipe 17. One side of the connecting pipe 17 is fixedly connected to the interior of the hollow box 18. A reagent tank 19 is provided on the top of the hollow box 18. The top of the hollow box 18 is fixedly connected to the bottom of the reagent tank 19. A solenoid valve 113 is provided on the bottom of the reagent tank 19, and the bottom of the reagent tank 19 is fixedly connected to the outer side of one end of the solenoid valve 113. The connection is as follows: an actuator 112 is installed on one side of the solenoid valve 113, and the interface between the solenoid valve 113 and the actuator 112 is connected by a wire. A controller 110 is installed at the interface of the actuator 112, and the interface between the actuator 112 and the controller 110 is connected by a wire. A concentration sensor 111 is installed at the interface of the controller 110, and the interface between the controller 110 and the concentration sensor 111 is connected by a wire. One end of the concentration sensor 111 is in contact with the interior of the flotation cell 11. A CNC table 114 is installed on one side of the flotation cell 11, and the interface between the flotation cell 11 and the CNC table 114 is connected by a wire. 4 is fixedly connected to one side of the flotation cell. An overflow trough 115 is provided on one side of the flotation cell. One side of the flotation cell is fixedly connected to one side of the overflow trough 115. A telescopic rod 116 is provided on the inner wall of the overflow trough 115. One end of the telescopic rod 116 is fixedly connected to the inner wall of the overflow trough 115. A scraper 117 is provided on the other end of the telescopic rod 116. One side of the scraper 117 is fixedly connected to the other end of the telescopic rod 116. An air inlet pipe 118 is provided on the inner wall of the flotation cell. One end of the air inlet pipe 118 is fixedly connected to the inner wall of the flotation cell. A booster pump 119 is provided on one end of the air inlet pipe 118. One end of the air inlet pipe 118 is fixedly connected to one end of the booster pump 119.

[0027] In this embodiment, when the device is in use, different reagents are introduced into the reagent tank 19. At this time, the controller 110 sends a command to the actuator 112 to open the solenoid valve 113, allowing the liquid in the reagent tank 19 to enter the hollow tank 18. Subsequently, the pump body 16 is started, which transports the liquid in the hollow tank 18 to the flotation cell 11 through the connecting pipe 17. After entering the flotation cell 11, the motor 15 is started, causing the gear 13 to start rotating. As the gear 13 rotates, the rubber gear 14 is affected, driving the other gears 13 to rotate as well. This causes the roller 12 to mix and stir the liquid in the flotation cell 11, ensuring that the reagents are evenly dispersed in the flotation cell 11. Therefore, by sending a command to the actuator 112 through the controller 110, the entire device is automated.

[0028] Secondly, if the liquid concentration is insufficient, the concentration sensor 111 will send a command to the controller 110, which will then transmit the command to the actuator 112 to open the electronic valve and allow the liquid to flow out. The liquid will then be introduced into the flotation cell 11 in the same way. Therefore, since the system can monitor the liquid concentration in real time, it can respond promptly and take adjustment measures quickly without manual intervention. Furthermore, the controller 110 accurately controls the amount of reagent added based on the data provided by the concentration sensor 111 to ensure that the liquid concentration is within the appropriate range. In addition, through the CNC console 114 installed on one side of the flotation cell 11, the operator can easily perform parameter settings, equipment adjustments, and other operations through the touch screen. This simplifies the operation process and reduces the operator's workload.

[0029] In addition, during the stirring process of the liquid in the flotation cell 11, the booster pump 119 is started, and gas is transported into the flotation cell 11 through the air inlet pipe 118, which will form a large number of fine bubbles. These bubbles will come into contact with the hydrophobic mineral particles in the slurry and cause these particles to adhere to the surface of the bubbles. Then, the telescopic rod 116 is retracted, so that the scraper 117 hangs these bubbles into the overflow tank 115, thereby realizing the separation and collection of mineral particles.

[0030] Example 2

[0031] like Figures 1-4 As shown, the buffer mechanism 2 includes a base 21, an elastic plate 22 is provided inside the base 21, the bottom side of the elastic plate 22 is fixedly connected to the inside of the base 21, a fixing plate 23 is provided at one end of the elastic plate 22, the bottom of the elastic plate 22 is fixedly connected to the bottom of the fixing plate 23, the outer side of the bottom end of the fixing plate 23 slides perpendicularly to the inner wall of the base 21, and a hollow box 18 is provided at the top of the fixing plate 23, the top of the fixing plate 23 is fixedly connected to the bottom of the hollow box 18.

[0032] In this embodiment, a fixed plate 23 is installed at the bottom of the hollow box 18, and the bottom of the fixed plate 23 has a spring plate 22. Since the hollow box 18 is equipped with a medicine tank 19 and contains liquid with fluidity, the spring plate 22 can alleviate the impact and vibration, thereby increasing the risk of wear and damage to the equipment and protecting the safety and stability of the medicine tank 19 and pipeline. During the mitigation process, the fixed plate 23 will slide up and down in the base 21. This ensures that the fixed plate 23 always moves along the predetermined track when mitigating impact and vibration, without causing unnecessary jamming, and makes the impact and vibration force evenly distributed in the base 21.

[0033] Working principle:

[0034] like Figures 1-4 As shown, by introducing different reagents into the reagent tank 19, the controller 110 sends a command to the actuator 112 to open the solenoid valve 113, allowing the liquid in the reagent tank 19 to enter the hollow tank 18. Subsequently, by starting the pump body 16, the liquid in the hollow tank 18 is transported to the flotation cell 11 through the connecting pipe 17. After entering the flotation cell 11, the motor 15 is started, causing the gear 13 to start rotating. Then, the roller 12 mixes and stirs the liquid during flotation, ensuring that the reagents are evenly dispersed in the flotation cell 11. If the liquid concentration is insufficient, the concentration sensor 111 will send a command to the controller 110, which will then transmit a command to the actuator 112 to open the electronic valve and allow the liquid to flow out. The liquid is then introduced into the flotation cell 11 in the same way. Therefore, since the system can monitor the liquid concentration in real time, it can respond promptly and take adjustment measures quickly.

[0035] By installing a fixed plate 23 at the bottom of the hollow box 18, and having a spring plate 22 at the bottom of the fixed plate 23, the impact and vibration can be mitigated, thereby increasing the risk of wear and damage to the equipment and protecting the safety and stability of the medicine tank 19 and pipelines. During the mitigation process, the fixed plate 23 will slide up and down within the base 21, which ensures that the fixed plate 23 always moves along the predetermined track when mitigating impact and vibration.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
