Technical Field

[0001] This utility model belongs to the field of flotation reagent proportioning technology, and in particular relates to a quantitative proportioning device for flotation reagents. Background Technology

[0002] Flotation reagents are chemical agents used in the mineral flotation process. They achieve effective separation of minerals by changing the physicochemical properties of the mineral surface. They play a crucial role in mineral processing. When producing flotation reagents, it is necessary to use a quantitative proportioning device to accurately control the proportion of raw materials such as capture agents, frothers, and modifiers to ensure the quality of production.

[0003] However, existing flotation reagent mixing devices typically use a single stirring rack or stirring blade to mix the raw materials for flotation reagent preparation. This results in low stirring efficiency and an inability to effectively solve the agglomeration problem of the mixed raw materials, leading to low preparation efficiency and poor results. There is a technical problem that the raw materials for flotation reagent preparation cannot be stirred sufficiently and efficiently to improve mixing and efficiency. Utility Model Content

[0017] Please see Figure 1-4 As shown, this utility model is a flotation reagent quantitative proportioning device, including a preparation tank 2, a base frame 1 disposed at the bottom of the outer side of the preparation tank 2, and a top frame 4 disposed at the top of the preparation tank 2, and further including: A liquid feeding hopper 5 is installed inside the top of the top frame 4 on one side. A solenoid valve 14 is installed at the bottom of the liquid feeding hopper 5 to control its opening and closing. A powder feeding hopper 6 is installed inside the top of the top frame 4 on the other side. Through-sleeves 8 are installed on both sides of the top of the preparation tank 2. The bottom ends of the liquid feeding hopper 5 and the powder feeding hopper 6 pass through the interior of the through-sleeves 8, and the bottom diameter of the liquid feeding hopper 5 and the powder feeding hopper 6 is smaller than the inner diameter of the through-sleeves 8. A control valve 9 is installed at the bottom of the preparation tank 2 to control the opening and closing of the material discharge port at the bottom of the preparation tank 2. The powder feeding hopper 6 is equipped with a feeding mechanism, which includes a screw conveyor shaft 12 and a drive motor 7. The drive motor 7 is located at the middle position of the top of the powder feeding hopper 6. The screw conveyor shaft 12 is rotatably connected to the middle position of the top of the powder feeding hopper 6. The top of the screw conveyor shaft 12 is fixed to the output end of the drive motor 7. The bottom end of the screw conveyor shaft 12 extends to the bottom end of the powder feeding hopper 6. When it is necessary to transport solid material to the preparation tank 2, the drive motor 7 is started to drive the screw conveyor shaft 12 to rotate at the bottom end of the powder feeding hopper 6, thereby uniformly transporting the powder to the inside of the preparation tank 2. As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a rotating shaft 10 is rotatably connected to the middle position of the top of the preparation tank 2. A stirring blade 16 is provided on the outer side of the rotating shaft 10. A fixing frame 15 is provided near both ends of the outer side of the rotating shaft 10. A stirring motor 3 is provided at the middle position of the top of the preparation tank 2. The top of the rotating shaft 10 and the output end of the stirring motor 3 are fixed together. The stirring motor 3 drives the rotating shaft 10 to drive the stirring blade 16 to stir and mix the flotation reagent preparation raw materials. The stirring blade 16 is provided with a through hole 18. When the stirring blade 16 stirs and mixes the flotation reagent, the through hole 18 increases the contact surface between the stirring blade 16 and the mixed raw materials, thereby shearing and breaking up the agglomerated mixed raw materials. A scraper 11 is provided between the two sides of the fixing frame 15. A polyethylene scraper 17 is provided on the outer side of the scraper 11. The outer side of the polyethylene scraper 17 is in contact with the inner side wall of the preparation tank 2. When the rotating shaft 10 rotates, the fixing frame 15 drives the scraper 11 and the polyethylene scraper 17 to scrape off the reagent attached to the inner side wall of the preparation tank 2. When the raw materials for flotation reagent preparation are quantitatively fed into the preparation tank 2, the stirring motor 3 located at the top center of the tank is started to drive the rotating shaft 10 fixed to its output end to rotate inside the preparation tank 2. When the rotating shaft 10 rotates, it drives the stirring blade 16 on its outer side to rotate. The stirring blade 16 with through holes 18 shears and breaks up the agglomerated mixed raw materials when stirring and mixing the flotation reagent, improving the agglomeration phenomenon of the mixed raw materials and thus accelerating the mixing rate. When the rotating shaft 10 rotates, it can also drive the scraper 11 and the polyethylene scraper 17 attached to the inner side wall of the preparation tank 2 through the fixed frame 15 on its outer side to scrape off the powder and liquid material attached to the inner wall of the preparation tank 2 to ensure the mixing quality and facilitate the cleaning of the device after the quantitative mixing of flotation reagent is completed. As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the weighing and metering component is located between the outside of the liquid feeding hopper 5 and the powder feeding hopper 6 and the top of the top frame 4. The weighing and metering component includes an "L"-shaped connecting seat 21, an upper stabilizing seat 19, a weighing sensor 13, and a lower stabilizing seat 20. The connecting seat 21 is located on the outside of the liquid feeding hopper 5 and the powder feeding hopper 6, and the connecting seats 21 are arranged at equal intervals on the outside of the liquid feeding hopper 5 and the powder feeding hopper 6. The position of the component is positioned by the connecting seat 21 to ensure the accuracy of weighing and metering. The upper stabilizing seat 19 is provided at the bottom of the connecting seat 21, and the lower stabilizing seat 20 is provided on both sides of the top of the top frame 4 at positions corresponding to the upper stabilizing seat 19. The weighing sensor 13 is provided between the upper stabilizing seat 19 and the lower stabilizing seat 20. The weighing sensor 13 is used to accurately weigh the liquid feeding hopper 5 and the powder feeding hopper 6 to accurately control the amount of flotation reagent raw materials added. The upper stabilizing seat 19 and the lower stabilizing seat 20 are used to limit and stabilize the weighing sensor 13. In use, the upper stabilizing seat 19 is positioned by the L-shaped connecting seat 21 located on the outside of the liquid feeding hopper 5 and the powder feeding hopper 6. The weighing sensor 13 is stably installed by the upper stabilizing seat 19 and the corresponding lower stabilizing seat 20 installed on the top frame 4. When quantitatively mixing flotation reagents, the weighing sensor 13 located between the inner sides of the upper stabilizing seat 19 and the lower stabilizing seat 20 is used to weigh and measure the liquid feeding hopper 5 and the powder feeding hopper 6 as a whole, so as to accurately measure the amount of flotation reagent mixed raw materials fed into the preparation tank 2. Working Principle: When using the flotation reagent quantitative proportioning device, the liquid and solid raw materials for flotation reagent proportioning are first loaded into the liquid feeding hopper 5 and the powder feeding hopper 6 respectively. The weighing sensor 13 weighs both materials and saves the data. During quantitative proportioning of flotation reagents, the solenoid valve 14 controls the opening of the liquid feeding hopper 5, allowing the proportioning liquid to flow from the hopper 5 into the preparation tank 2. Simultaneously, the weighing sensor 13 converts the mass or force of the material into a measurable electrical signal output to measure the total weight of the liquid feeding hopper 5 in real time. When the liquid reaches the quantitative amount, the weighing sensor 13 controls the solenoid valve 14 to close via the electrical signal output. Similarly, the weighing sensor 13... The weight of the powder feeding hopper 6 is weighed and the drive motor 7 drives the screw conveyor shaft 12 to deliver the quantitative flotation reagent powder downwards. After the flotation reagent raw materials are quantitatively fed into the preparation tank 2, the stirring motor 3 is started to drive the rotating shaft 10 to rotate the stirring blade 16. The stirring blade 16 with through holes 18 inside is used to shear and break up the agglomerated mixed raw materials, improving the agglomeration phenomenon of the mixed raw materials. At the same time, the fixed frame 15 drives the scraper 11 and the polyethylene scraper 17 attached to the inner side wall of the preparation tank 2 to scrape off the powder and liquid material attached to the inner wall of the preparation tank 2 to ensure the mixing quality. After the quantitative flotation reagent is quantitatively proportioned, the control valve 9 can be opened to discharge it, thus performing the quantitative flotation reagent proportioning operation accurately and efficiently.
